    In an ink baffle in an ink reservoir of a rotary printing machine, a profile body is arranged within an ink distribution channel to prevent turbulence within the ink. To alter the ink pressure between the profile body and the screen roller, the profile body is arranged to be able to pivot or to rotate, depending on its design.

    专利说明:

    The invention relates to the equipment of rotary printing machines, in particular, to a knurling device of a rotary printing press which interacts with a knurling roller.
    The purpose of the invention is to increase the degree of uniformity of paint application to the knurling roller.
    FIG. 1 shows the proposed rolling device, in which the figured body (streamlined shape) is made with the possibility of rotation; in fig. 2 - the same one in which the mechanism for moving the figured body is depicted; FIG. 3 is a section A-A in FIG. 2; in fig. 4 shows a rolling device in which the shaped body is rotatable; in fig. 5-7-shapes of figure body, cross sections.
    Roll roller 1 with a mesh surface is installed with the possibility of rotation in the bed (not shown). Parallel to the axis of rotation of the roller 1, a knurling means 2, designed in the form of a bar and interacting with the roller 1, is installed, provided along the length of the roller with a recess 3 and upper 4 and lower 5 squeegees. Serving as the paint-distributing chamber, the recess 3 has smooth rounded inner walls 6. In the middle of the recess 3, there is an ink supply port 7 adapted to be connected to an ink supply source (not shown). The squeegee 4 is outside screwed to the upper inclined surface 8, and the squeegee 5 to the lower inclined surface 9 of the knurling means 2. The notch 3 on the face sides 10 and 11 is covered by side sheets 12 and 13, which partially protrude beyond the end surfaces 14 and 15 of the roller 1. In the recess 3 is placed free-flowing figured body 16. installed with the possibility of rotation through attached to the front sides 10 and 11 of the pins 17 and 18 in the side flaps 19 and 20. The latter are screwed sideways to the rolling means 2 so that the side sheets 12 and 13 are installed between
    sh
    with
    Che
    H
    rolling means 2 and side flaps 19 and 20.
    In the direction of the axis, the figured body 16 has almost the same length as the tire b of roller 1, Figured body 16 has an elliptical cross section.
    Thus, rotation of the shaped body 16 around the axis of rotation 21 leads to a change in the minimum width Zmin of the gap 3 formed by the roller 1 and the side surface 22 of the figure body 16 facing the roller 1. In the direction of rotation of the roller 1, the paint force F in the gap S is the largest immediately before wide
    5Min of gap S. Bearing capacity of the t-printing ink and thus the ink strength on the roller 1 can be calculated by the following equation (see also VDI-Forschungsheft, 391.82-85):
    F-1,225.b., Y1 + V2) 4jVir-Ј
    where the viscosity of the paint;
    P is the radius of the roller 1;
    G2 is the radius facing the roller 1 of the side surface 22;
    Vi is the circumferential speed of the roller 1;
    V2 - circumferential speed of the figured body 16 (for example, equal to 0, since the figured body 16 is fixed stationary) b - the length of the figured body 16.
    Thus, a change in the very minimum width of SMUH leads to a direct change in the strength of the paint on the roller 1.
    The rotation of the figure body 16 is carried out by means of mounting devices 23 mounted externally on the side flaps 19 and 20, consisting of a setting spindle 24, passed through a threaded through hole 25 attached to the side plates 19 and 20 of the holder 26. The setting spindle 24 has a ball at the end 27 28, extending into the vertical groove 29 of the lever 30. The latter is firmly fixed to twisting on the passage through the side sheets 12 and 13 and the side flaps 19 and 20 of the pins 17 and 18. The setting spindle 24 is controlled by Static preparation head 31 which may be provided, e.g., knurling, so that it may easily serve manually. For the purpose of possible further control, it is also possible to provide a servomotor.
    By means of the installed tools 23, the figured body 16 can be rotated from the middle position (shown by hatching in Fig. 2) depending on the direction of rotation of the roller 1 and the required paint force F to the side of the roller 1 by an angle (p, for example ± 20 °). In Fig. 1 the solid line represents the position
    rotation of the figured body 16 in the case of rotation of the roller clockwise, and bar-chart shows the possible position of the figured body 16 in the case of rotation of the roller 1 counterclockwise. FIG. 4 notch
    3 is circular and a cylindrical figured body 16 is installed therein, which is rotatably mounted in the side flaps 19 and 20 and is adjacent to the roller 1. Figured body 16 is driven in
    action from roller 1 by friction. It is also possible to drive the figure body 16 by means of passing aids. In addition, it is also possible to provide means (for example, installation
    figure body 16 in eccentric sleeves) to change the distance of the axes of the figure body 16 and roller 1, resulting in greater slippage between the roller 1 and the figure body 16. This leads to a decrease in the circumferential speed (V2) of the figure body 16 and at the same time expanding the minimum width Zmin, so that the paint pressure on the roller 1 is reduced. Figured body 16 may also be configured according to FIG. 5-7.
    FIG. 5 shows a cross section of the profile body 16 having a convex shape on the side facing the roller 1 and a concave shape on the side of the reverse flow of paint. The ends of the figure body 16 are rounded, and the rounding has a larger radius than the other rounding (along the profile of the blade). The figured body 16 in FIG. 6 mainly corresponds to the profile body 16 in FIG. 5, however, has the same end radii. The figured body 16 in FIG. 7 has two concave side surfaces.
    In order to reliably prevent possible hydrodynamic disturbances or eddies of the ink, it is advisable to make the surfaces of the figure body 16 smooth.
