    Descriptive Report of the Invention Patent for DOUBLE-BELT PRESS AND PROCESS TO PRODUCE A PRODUCT IN THE FORM OF A PLATE, USING A DOUBLE-BELT PRESS.
    [0001] The present invention relates to a double-belt press with a first, revolving plastic strap and a second, revolving plastic strap, the plastic straps having a first low flexural strength and a slit being formed. product between the sections facing, in relation to each other, of the plastic straps for the formation of a product in the form of a plate. The invention also encompasses a process for producing a plate-shaped product with a double-belt press.
    [0002] From the European patent EP 1 045 751 B1 a double-belt press has become known with a product slit between the two plastic straps, arranged in parallel by segments. A basic thermoplastic product is spread over an application area on a lower elastic band and then a plate-shaped product is formed between the two plastic bands. A connection of the thermoplastic basic product with a stable plate-shaped product is verified by an almost pressure-free solder of the thermoplastic basic product, using a maximum pressure of 20 kPa (0.2 bar). This well-known double-belt press has disadvantages when it comes to producing thicker plate products and / or when it comes to processing basic fibrous products, for example, in processing natural fibers.
    [0003] With the present invention, an improved double belt press and an improved process to produce a plate product with a double belt press should be offered.
    [0004] According to the invention, a
    Petition 870190106054, of 10/21/2019, p. 6/30
    2/16 double belt press with a lower, revolvable first plastic strap and a second, higher revolving plastic strap, with the plastic straps having a first resistance to reduced pressure and a product slit being formed between the sections facing one in relation to the other of the plastic straps, aiming at the formation of a product in the form of a plate, in which a first revolving lower steel strap and a second revolving upper steel strap are provided, and said steel straps present a second resistance flexural strength, high compared to the flexural strength of cable ties, a forming segment is formed between the sections facing each other in relation to the steel belts, and the forming segment is part of the product slit and in the forming segment , during operation, the first lower steel band extends in parallel and against a dorsal side of the first plastic strap, spaced in relation to the product slit, and in the forming segment, in operation, the second upper steel strap protrudes in parallel and adjacent to a dorsal side of the second plastic strap, spaced in relation to the slit products.
    [0005] By predicting the steel straps that form a forming segment, leaning against a dorsal side of the plastic straps, in segments, the advantages of a double strap press with plastic straps can be surprisingly simple with those of a double belt press with steel belts, without having to accept the respective disadvantages. With steel straps, in the forming segment, a significantly higher pressure can be exerted on the product crack and the basic product there, than this would be possible with plastic straps. In particular, the greater flexural strength of steel belts allows to preserve a markedly uniform pressure, compared to
    Petition 870190106054, of 10/21/2019, p. 7/30
    3/16 cable ties, also covering greater length of the forming segment. The basic product is also specifically integrated in the forming segment, however it is always in exclusive contact with cable ties, so that one should not fear adherence of the basic product to steel belts. Also from an energetic point of view, the double belt press according to the invention has advantages. Therefore, in the forming segment, a constant temperature can be maintained throughout the process. Based on the greater heat preservation capacity of steel belts, compared to cable ties, this is feasible with reduced losses and also by heating devices that are not immediately located in the formation area. The disadvantages that are present in the specific steel belt presses, due to the necessary cooling of the steel belt, in different segments of a product slit, do not appear in the double belt press according to the invention, because the steel belts form - only in the forming segment - part of the product slit. A cooling of the product in the product slot may then occur, for example, downstream of the forming segment, between the plastic straps. Based on the poor thermal conductivity of plastic material, the heat losses of the double belt press according to the invention, thus being considered lower rates than in the specific steel belt presses. With the double-belt press according to the invention, very thick plate-shaped products can also be produced without problems, as well as basic products can be formed for plate-shaped products that require a high compression pressure in the slit. product. Even so, the double belt press according to the invention, compared with specific steel belt presses, can be made at a more advantageous cost, because steel belts are only necessary in the shape segment

    4/16 pain and in relation to the production process of the product in the form of a plate can be operated in the same way, free from problems such as conventional double-belt presses with plastic straps. According to the invention, heating and / or cooling devices are also provided to heat or cool the first and second plastic bands, being provided outside the forming segment. For example, the plastic strap can be heated in a place of adduction and also in a part of the product slit, upstream of the forming segment. Downstream of the forming segment, the plastic straps can then be cooled down without any problems. Energy losses are, in this case, reduced, because cable ties in view of their reduced heat accumulation capacity and accumulate less thermal energy, transmitting it along the product crack. Already outside the forming segment, with the steel straps, the product can be pre-molded in the form of a plate.
    [0006] In extension of the invention, heating and / or cooling devices are provided to heat and cool the first and second steel belts.
    [0007] By heating and / or cooling the steel band, the forming segment, as part of the product slit, can be maintained smoothly at an approximately constant temperature. This is because the high heat accumulation capacity of the steel belts allows uniform temperature throughout the length of the forming segment.
    [0008] In extension of the invention, compression devices are provided in order to apply a compression pressure in the forming segment on a product, disposed between the plastic straps, this pressure being exerted by the steel straps.
    [0009] Such compression devices may be, for example, roller chains, compression cylinders, compression plates or
    Petition 870190106054, of 10/21/2019, p. 9/30
    5/16 similar units, which move on a dorsal side of the respective steel strap. For that, one can use compression devices already approved and known in steel belt presses. If, for example, compression cylinders that are reciprocally spaced in the longitudinal direction, due to the high flexural strength of the steel belt, despite the essentially linear contact of the compression cylinder, the uniformized compression pressure path can be achieved. The compression pressure path is essentially more uniform than when a plastic belt with reduced flexural strength is compressed by several compressing cylinders, arranged sequentially.
    [00010] Advantageously, the compression pressure will be in the range of 10 kPa up to 5000 kPa (0.1 bar up to 50 bars).
    [00011] Through a pressure range of this type, products with difficult processing or thick plate products can be worked well. Even so, the costs of the double belt press are kept in a reduced range, because compression pressures above 5000 kPa (50 bars), as they can be achieved without difficulties with conventional double steel belt presses, are not necessary.
    [00012] In an extension of the invention, the compression devices are shaped, so that through the steel straps apply to the forming segment an essentially uniform compression pressure throughout the forming segment.
    [00013] The prediction of a so-called isobaric compression pressure in the forming segment, due to the greater flexural strength of the steel straps and their mechanical load capacity, which is generally greater compared to plastic straps, can be achieved without problems. For example, compression devices are
    Petition 870190106054, of 10/21/2019, p. 10/30
    6/16 formed to hold a dorsal side of the steel band with pressurized fluid, away from the product gap.
    [00014] In extension of the invention, the plastic straps at least on their side facing the product slot have a non-stick coating.
    [00015] A non-stick coating of this type may consist, for example, of Teflon and is conveniently adjusted to the type of product in the shape of a plate to be produced. By predicting a non-stick coating of this type, the product in the form of a plate produced can be easily separated at the end of the product slit, being removed from the plastic straps and, for example, the product in the shape of a plate can still be removed in a very product crack. A non-stick coating can, for example, also be made by continuously spraying a liquid upstream of the product slit. A non-stick coating can also be shaped like a so-called nano-coating that produces a considerably smaller contact angle in the plastic straps of a product to be processed. Such a nano-coating can, for example, produce the so-called lotus effect, in which a contact angle between a drop of product and the plastic band occupies a very high value of about 160 °. This corresponds to extremely low wettability. Preferably, contact angles of 90 ° or greater than 90 ° are used. The angle of contact between the edge of a product drop and a surface on which the product drop rests will also be referred to as a marginal angle or wetting angle.
    [00016] In extension of the invention, at least in the forming segment, lateral limitations for the lateral limitation of the product slit are provided.
    [00017] In this way, it can be avoided that due to an event
    Petition 870190106054, of 10/21/2019, p. 11/30
    7/16 tual pressure exerted on the forming segment, the basic product to be processed flows laterally between the cable ties.
    [00018] In extension of the invention, a double belt press machine chassis has a modular construction and, seen in the longitudinal direction of the product slot, is formed of several modules interconnected separately. Conveniently, the two revolving steel straps, as well as the deviations for the steel straps are arranged within a modular segment of the machine chassis.
    [00019] Through a modular construction, with reduced additional construction effort, double belt presses of variable length and of variable construction can also be realized, which will then be specially adjusted to a plate-shaped product to be produced. Also, retrofitting the double belt press for another product to be produced will be considerably easier. The arrangement of the two revolving steel straps within a module, as well as additionally, possibly also heating devices and compressing rollers within this modular segment, allows the retrofitting of a double belt press with revolving steel straps for the forming of the press. double strap according to the invention. The heating devices, integrated directly into the module, can be specially adapted to the requirements of revolving steel straps.
    [00020] In extension of the invention, a length of the forming segment is less than half the length of the product slit, especially less than a tenth of the length of the product slit.
    [00021] In this way, the double-belt press according to the invention can be realized at an advantageous cost. Steel belts are comparatively expensive and also the necessary compression devices contribute to the high costs. As a competition 870190106054, of 10/21/2019, p. 12/30
    8/16 length of the forming segment represents only a fraction of the length of the product slit, the additional costs caused by the steel belt can be kept to a small extent. Even so, the disadvantages of higher compression pressure in the forming segment that can be applied by means of steel straps can be used.
    [00022] The underlying problem of the invention will also be solved by a process to produce a product in the form of a plate with a double belt press with the following steps: application of at least one basic product in an application region on a first plastic belt , introduction of at least one basic product in a product slit between the first and the second plastic band, tempering and / or compressing at least one basic product in the product slot, introduction of at least one basic product in a forming segment, being that the forming segment forms part of the product slit and the temple and / or protection of at least one basic product in the forming segment by means of two steel straps that abut the forming segment on a dorsal side of the plastic straps, remote from the to the product crack.
    [00023] The quenching and / or compression of at least one basic product in the forming segment by means of two steel straps allows the production of very thick plate products as well as plate products from basic products that require comparatively intense pressure on their production. Here, in this case, one can deal, for example, with plate products that contain natural fibers or that, in order to combine different particles of the basic products in a homogeneous mass, require a slightly higher pressure. Even when greater pressure should not be applied to the forming segment, steel straps allow - seen by the length of the forming segment - to be applied
    Petition 870190106054, of 10/21/2019, p. 13/30
    9/16 simple a uniform thermal current within the basic product. Based on the intense heat accumulation capacity of steel belts, a uniform temperature distribution across the forming segment can be achieved in this way, with simple means. Unlike what happens when using double-belt presses with continuous steel belts over the entire length, heat losses are considerably reduced, because steel belts can remain at a constant temperature throughout the length of the forming segment and do not need be heated in different segments and then cooled again.
    [00024] In extension of the invention, the application, especially the distribution, of at least one basic thermoplastic product is provided for in the adduction area. Advantageously, the basic product will be heated in the area of the adduction and / or in the product slit, in order to achieve particle welding of at least one thermoplastic basic product between them.
    [00025] In extension of the invention, it is provided for the quenching and / or compression of at least one basic product in the product slit, outside the forming area.
    [00026] In extension of the invention, it is provided to coat at least one layer in the product slit.
    [00027] The coating can be made, for example, with decorative layers or also thin laminates or similar materials that protect products in the form of a plate against environmental influences. The coating can be carried out with the process according to the invention without any problems and can make even sticky products, difficult to process, processable, because there is no longer a need for direct contact between the product and the cable ties.
    [00028] Other features and advantages of the invention result from the claims and the following description of embodiments
    Petition 870190106054, of 10/21/2019, p. 14/30
    Preferred 10/16 of the invention in connection with the drawings.
    [00029] Individual characteristics of the different modalities presented can in this case be combined at random without going beyond the context of the invention. The figures show:
    Figure 1 schematic presentation of a belt press, according to the invention and
    Figure 2 is a cross-sectional view of a double belt press according to the invention, according to another embodiment.
    [00030] The schematic presentation of a double belt press 10 in figure 1, according to the invention, features a first lower revolving plastic belt and a second upper revolving plastic belt 14. An upper section of the first plastic band 12 defines an application area in a region 16, in which a basic product, for example, a thermoplastic basic product, can be applied on the lower plastic band 12. Above this application area 16 is provided a dispensing device 18 which essentially consists of a funnel for adding the basic product or several components in the form of a granulate or in the form of fibers. At the exit of the funnel, a dispensing cylinder 20 is provided that extends the entire width of the lower plastic strap 12. In its circumference, the dispensing cylinder 20 has bristles, to guarantee a uniform removal of the basic product present in the form of granules, from of the funnel 18 and so that this basic product is then distributed with a uniform layer thickness over the lower plastic strap 12.
    [00031] Downstream of the dispensing device 18, a first heating device 22 is provided which can produce, for example, through infrared radiation, a heating of the basic product distributed.
    [00032] Downstream of adduction area 16 follows a product slit 24 that extends over a product slit area 25,
    Petition 870190106054, of 10/21/2019, p. 15/30
    11/16 from a front deflecting roller 26 for the upper plastic strap 14 to a rear deflecting roller 28 for the upper plastic strap 14. A rear baffle roller 30 for the lower plastic band 12 is located just in front of the rear baffle roller 28. Throughout the region of the product slit 24, the plastic straps 12, 14, using suitable rollers 32, are conducted exactly parallel to each other. Just as an example, here are shown four compression rollers, that is, guide rollers 32. Compressor rollers 32 and possibly other rollers indicate that in the presence of a basic product in product slot 24, the plastic straps 12, 14 are essentially move away from each other. If no basic product is found in the product slot 24, then the upper plastic strap 14, in view of its comparatively reduced tension and reduced flexural resistance, is supported by large segments of the product slot 24 in the lower plastic strap.
    12.
    [00033] The two cable ties 12, 14 revolve in the area of the double belt press 10, at exactly the same speed. Between a basic product at the beginning of product slot 24, that is, a plate-shaped product at the end of product slot 24 and cable ties 12, 14, there is therefore no relative speed.
    [00034] Compression and heating devices 34 are provided in the rear area of the product slit 24, on the rear side of the lower plastic band 12 and on the rear side of the upper plastic band 14. Through these compression and heating devices 34, a height of the product slit will be maintained exactly at the predetermined value and at the same time the plastic straps 12, 14 and with these the basic product existing in the product slit will also be heated. The double-belt press shown 10 is intended for processing thermoplastic materials and heating, using compression and heating devices 34, produces
    Petition 870190106054, of 10/21/2019, p. 16/30
    12/16 in this way a process of welding the different particles of the basic product into the product slot 24. A pressure reigning in the area of the heating compression devices 34 in the product slot is comparatively reduced and is in the order of magnitude between 20 and 200 kPa (0.2 and 2 bar). In the case of higher compression pressures, the plastic straps 12, 14 show very rapid wear and / or unwanted surface structures are formed in the finished plate product, so that the plastic straps 12, 14, due to their reduced flexural strength, are not in a position to distribute pressure applied to a localized point over a large area.
    [00035] Downstream of the compression and heating devices 34, a lower, revolving steel strip 36 is provided, and a second, revolving steel strip 38 is provided. The two revolving steel straps 36, 38 are arranged in such a way that the upper section of the lower steel strap 36 touches a rear side of the lower plastic strap 12, spaced away from the product slot 24. The upper steel strap 38 it is so arranged in its lower section that it leans against a rear side of the upper plastic strap 14, opposite the product slit 24. Through the two steel straps 36, 38 revolving, you can thus, in a forming segment 40 forming a part of the product slit 24, a compression pressure is exerted on the plastic straps 12, 14 and, thus, on the product existing in the product slit 24. In this case, the upper section of the lower steel strap 36 and the lower section of the upper steel band 38 will be pressed against the product slot 24 by means of a revolving roller chain 42, 44. A compression pressure in the product slit 24, within the forming segment 40, is typically located in the range of 1000 to 2000 kPa (10 bars to 20 bars). Such pressure will be necessary in order to
    Petition 870190106054, of 10/21/2019, p. 17/30
    13/16 also provide basic products that are difficult to process in the form of a plate, and in order to obtain a sufficiently high density of the produced plate products. For example, fibers, especially natural fibers with thermoplastic filler material, can be processed to form plate products. The compression pressure in the forming segment 40 will then be sufficient, so that also in the case of comparatively high stiffness of the fibers to be processed, to achieve a flat surface of the plate-shaped product produced.
    [00036] In the region of steel belts 36, 38 heating devices 46 are provided, with heating devices 46 subjecting the lower section of the lower steel belt 36, that is, the upper section of the upper steel belt 38. Based on comparatively high heat accumulation capacity of steel belts 36, 38, heating devices 46 can be arranged in the position shown and therefore comparatively well away from product slit 24, since steel belts 36, 38 can accumulate enough heat. In addition to the heating devices 46, it can also be provided that the respective front deflecting roller 48, that is, 50, for steel belts 36, 38, may be heated. For this purpose, fluid channels 52 may be provided in the inner compartment of the deflector rollers 50, 48.
    [00037] The double belt press 10, according to the invention, can therefore, without problems, also be used in such a way that through the steel belts 36, 38 no pressure is exerted, or almost no compression pressure, over the product slit 24, however the steel straps 36, 38 are held only in their position, in order to limit the product slit and therefore the height of the product in the form of a slab produced. In such a case, steel strips 36, 38 will only be used to introduce heat into the product slit 24.
    Petition 870190106054, of 10/21/2019, p. 18/30
    14/16 [00038] Downstream of the forming element 40, other compression rollers or guide rollers 32 or, for example, other heating sets may be provided.
    [00039] In the end area of the product slot 24, in the double-belt press shown 10, cooling devices are provided in the form of spray nozzles 54 that spray cooling water against the lower side of the upper section of the lower plastic belt 12. A rear side of the upper plastic strap 14, spaced away from the product slot 24, can, for example, be cooled, for example, by means of a fan 33 in a simple way. At the end of the product slot 24, the product in the form of a plate already produced can then be removed.
    [00040] The double belt press 10 also features sets for applying a coating. For this purpose, even before entering the product slit 24, a roller 60 is provided in which a layer 62 is applied to be applied as a coating. This layer 62, for example, a thin laminate will then be introduced together with the basic product, spread in the area of adduction 16, inside the product slit 24 and during the passage through the product slit 24 a union is made with the basic product. In this case, it is also possible, of course, to apply one or more coatings on both the underside and the upper side of the product in the form of a plate.
    [00041] The presentation in figure 2 shows a double belt press 70 according to the invention, according to another embodiment of the invention. The main operating mode of the double belt press 70 is the same as described on the basis of figure 1 and the double belt press 10, so that there is no renewed explanation of this main operating mode. The double belt press 70 has an adduction area 72, in which, by means of devices not shown, for example, dispensing device is applied a
    Petition 870190106054, of 10/21/2019, p. 19/30
    15/16 basic product on a lower plastic band 74. Downstream of the adduction area 72, a product slit area 76 begins, in which a product slit 78 - despite an entry and exit area has a constant height. After passing through the slit of products 78, the finished product can be removed in the form of a plate, already finished.
    [00042] A frame of the double-belt press machine according to invention 70 is modular in constitution and consists of eight modules 80 to 94 in all. The modules 80 to 94 have a closed and self-supporting frame that are joined with the others modules in a separable way. When forming or relocating a double belt press 70, according to the invention, it is therefore possible to insert or extract individual modules, with only the length of the plastic straps 74, 75 having to be adequate.
    [00043] Module 80 has a front deflector unit for the lower plastic strap 74. In the area of module 82, below the lower plastic strap 74, heating sets are provided. Module 84 shows the front deviation for the upper plastic strap 75, as well as heater sets, below the lower plastic strap 74. In module 86 there are heater sets, especially heating fans, in order to heat the lower plastic strap 74 and the upper plastic strap 75 and therefore also the basic product existing inside the product slot 78 and to weld its particles together. In module 88, compression heating devices are provided in the form of plates, as well as in the center of module 88, two compressor cylinders 89 are provided in order to adjust the height of the product within the product slot 78 to a previously defined value. Module 90 includes a lower revolving steel belt 96 and a higher revolving steel belt 98 which, in the area of a forming segment 100, extend parallel to each other.
    Petition 870190106054, of 10/21/2019, p. 20/30
    16/16 ra with the product slit and lean against a dorsal side of the plastic straps 74, 75, spaced from the product slit 78. In module 90, using steel strips 96, 98, it can be used a compression pressure on the product in the product slot 78 and / or heat can be introduced in the product slot 78, with the compression pressure typically being in the range between 1000 and 2000 kPa (10 and 20 bars). Compression and heating devices in the form of plates are also provided in module 92, and alternatively cooling in module 92 can also be performed. In module 94, the rear deflection for the lower plastic strap 74 and plastic strap 75 is provided. higher.
    [00044] Based on the representation of figure 2, it can be recognized that the forming segment 100, in which the two revolving steel straps are provided, is essentially shorter than the slit length of products 78. In this way, the press double belt according to invention 78, can be produced at an advantageous cost, because steel belts 96, 98, compared with plastic belts 74, 75, are expensive. Even so, within the module 90, a comparatively more intense compression pressure can be exerted on the product in the product slot 78, or a large amount of heat can be applied. Based on the high flexural strength of steel strips 96, 98, over the entire length of forming segment 100, a compression pressure with a uniform layout can be applied. The length of the forming segment 100 will be at most half the length of the product slit 78 and therefore can be up to less than one tenth in the length of the product slit 78.
