Description

Machines are known for pulling bristle out of hides using a feed conveyor and bristle-pulling straps. In the proposed machine, for the purpose of dividing the bristles into rows, a plank is used, equipped with oblique cuts, for clamping and pulling out the marked rows another friend is a movable plank located along with the first bar on the slider. The grabbing of the pulled out bristles and its transfer to the discharge conveyor is carried out by means of tongs located above the slats and controlled by a curly lock,

In FIG. 1 shows a front view of a car; FIG. 2 is a view from above; FIG. 3 is a side view of it; FIG. 4, 4-view in two projections of the movable bar; FIG. 5, 5 is a view of two projections of a fixed strap for dividing bristles into rows; FIG. b-forceps for gripping the pulled out bristles; FIG. 7-vertical section of the working body of the machine.

The proposed machine (Figs. 1, 2, 3, and 7) consists of an IG-conveyor 20, 21, 22, 75, on which the shchkur, two ridges 23, 2- / and a pulling device consisting of a slider 2 and located on there are two strips 5 (fig. 4, 4) and 25 (fig. 5, 5). The strap 3 is designed to clamp and pull the bristles, and the strap 25, provided with oblique

cutouts 25, serves to separate the bristles into rows. Above the bars 3 and 25 are located tongs 27 (Fig. 6), driven by a pulley / 2 and controlled by a figured washer 27. These tongs are intended to grip the pulled out bristles and transfer them in rows to the discharge conveyor 28.

A shaft 8 is placed in the middle of the machine (Figs. 1 and 3) mounted on two bearings 9 fixed in frame 7. A working pulley 10, an idler 77 and an additional pulley 72 are mounted on the shaft 8; from the latter, the movement is transmitted to the drum 13, on which, during the operation of the machine, a peeled skin without bristles is rolled. In addition to the pulleys, disks 15 and 16 are mounted on the shaft 8, fitted on the working sides with projections acting by means of levers 77 on the slider 2 and the bar 3 placed in it.

The machine operates as follows. The reeled-on drum 20 is inserted into certain slots of the machine. The end of the web, attached to the skin, is thrown over the intermediate rollers 27 and 22 and fixed on the drum 13.

After skinning the machine, the slider 2 is put into action by the action of the levers 77 begins to move backwards.

in the slot groove and at the same time

The bar 25 is moving with it.

The skin, moving forward, the priest, gives under the combs 23, which ruffle the bristles and put it in an upright position. Next, the bristles fall

under the horizontal comb 24. Last: flood the stubble back and then

collects it in bunches. Thus, the bristles located on the skin in different directions, under the action of

The comb 24 is assembled in parallel rows.

Plank 25, moving back and forth, captures the line of bristle and, under the influence of oblique cuts, 25 raises it. Skipping through the slots in the marked cuts, the bristles become vertical, falling into the space between the bar 25 and the clamping bar 3, which, when the slider 2 moves with its rollers, raises the bar elevations 5. With the further movement of the floor, the zune 2 stitch is clamped in the same direction the bristles are pulled out due to the fact that at this time fists on disks 15, slider 2

makes a pull and the bristles are pulled out of the skin. Then the slider goes back, pulled out, but still clamped by the bar J, the bristles are caught by the forceps 27 and dropped into the conveyor. Thus, the process is repeated again.

The subject matter of the invention.

Claims (2)

1. A machine for pulling bristle out of hides using a feed pelt of a conveyor and two stubble pulling stitches, characterized in that one of the slats 25 is provided with cut out cuts 25 (Fig. 5) designed to divide the bristles into rows, for the purpose of clamping and pulling these rows with the help of the movable bar 3, located together with the bar 25 on the slider 2 (Fig. 2, 4, 5, 7). 2. In the machine according to claim 1, use tongs 27 (Fig. 6) located above the slats 3, 25 and controlled by a figured washer 27 designed to grab the pulled out bristle and transfer it to the bypass rows 28 (Fig. 6, 3).
