    In a device for the melting and measured discharge of a thermoplastic adhesive, a sealing sleeve conveys the solid thermoplastic adhesive into the inlet end of a melting chamber. The sealing sleeve is formed of a temperature resistant, poor heat conductive material with good sliding properties, such as polytetrafluoroethylene. Further, the sealing sleeve is provided with slots extending in the axial direction of the sleeve from the end more remote from the melting chamber toward the melting chamber.

    (54) DEVICE FOR MELTING AND DOSING THERMOPLASTIC ADHESIVE
    I. ,
    The invention relates to devices for melting and dispensing a thermoplastic adhesive and is used as a hand-held tool for a variety of gluing jobs. :
    A device for melting and metering a thermoplastic adhesive is known, which contains a melting chamber and a sealing collar mounted at the inlet of the melting chamber, made of heat-resistant antifriction one having a low thermal conductivity of the HP material.
    A disadvantage of the known device is the unreliable sealing of the melting chamber, due to the low elasticity of the sealing cuff. The sealing cuff is made of ter) anti-friction resistant, low thermal conductivity material, for example (.teflon), polytetrafluoroethylene, which is characterized by low elasticity. Wherein
    constructive implementation of the sealing cuff in the known device does not contribute to the increase of its elasticity.
    5 The purpose of the invention is to improve the sealing of the melting chamber. The goal is achieved by the fact that in a device for melting and dosing a thermoplastic adhesive,
    10 containing a melting chamber and a sealing collar installed at the inlet of the melting chamber, made of heat-resistant, antifriction and having a low thermal conductivity
    19, the sealing cuff is made with longitudinal slits on its entrance section.
    This seal cuff
    20 is equipped with an elastic element covering its entrance section. ,
    In addition, the elastic e.pement is made in the form of a nozzle from a rubber elastic material.
    In this case, the elastic element is made in the form of a sleeve with slots on the part of the length that are displaced relative to the slots of the sealing cuff.
    FIG. 1 shows the device in partial section, the first embodiment of the payment cuff, general view; in fig. 2 is the same, the second embodiment of the sealing. Mangles, in FIG. 3, section A-A in FIG. 2
    A device for melting and metering a thermoplastic adhesive includes a housing 1 with a handle 2 attached to it from the side. The handle 2 is provided with a button 3 and a tok ammunition TS The housing 1 houses a melting chamber 5 for melting grains 6 of adhesive material. A nozzle 7 is installed in the outlet part of the melting chamber 5. The inlet part of the melting chamber 5 is provided with a sealing lip 8 with longitudinal slots 8a at its inlet portion dividing the cuff into separate elastic tabs. The sealing cuff 8 is provided with an elastic element 9. made in the form of nozzles of rubber elastic material.
    The elastic element can be made in the form of a sleeve 10 with slots 10 o on a part of the length offset from the slots of the sealing cuff 8 (Figures 2 and 3).
    The device works as follows.
    When the button 3 is pressed, the grain 6 of the adhesive material is conveyed to the melting chamber 5 by means of a transport mechanism (not shown). When heated in the melting chamber 5, the grain 6 of the adhesive melts and turns into a liquid compound. At the entrance, the melting chamber 5 is locked with grains 6 of adhesive material that are still in a solid state. As a result of the movement of the particles 6 of the adhesive material into the melting chamber 5, a part of the molten glue is displaced from the chamber 5 and exits the nozzle 7.
    At the same time, the sealing cuff 8 prevents from the leakage of molten glue through the entrance of the melting chamber 5 Longitudinal slots 8a made in the inlet section of the sealing cuff increase the
    its elasticity. But at the same time, the presence of slots creates the danger of penetration through the cuff of liquid glue. Attached to the sealing cuff 8 nozzle 9 (Figure 1), which serves to overlap the longitudinal slots 80, also provides a clamping force acting on the tabs of the sealing cuff 8 in the radial direction.
    Installing the nozzle 9 directly on the sealing chamber 8 makes it easy to replace it if necessary.
    When performing the elastic element
    in the form of a sleeve 10 (Figures 2 and 3) with slots 10 (4 in part of the length, offset from the slots 8ci of the sealing cuff 8, the slots 8c | and the slots lOet mutually overlap
    elastic tabs located between the slits. This prevents the melted glue from escaping through the longitudinal slits 8c of the sealing collar 8. With sufficient elasticity formed by the lOd recesses of the tabs, the sleeve 10 itself is held on the sealing lip 8.
    The use of the present invention allows to increase the elasticity of the sealing cuff, which provides improved sealing. melting chamber.
