SU29222A1 - Sheepskin combing machine - Google Patents

Description

The proposed machine for combing sheepskins is stoning out of the frame, in the guides of which there is a slider carrying a comb and driven backwards by a crank from a flywheel. For raising and lowering the requirement, the latter is located in the slider rockingly on the axis. In order to retain the skin, a clip, driven by an aid of a system of levers, against an eccentric on the drive shaft is used.

In FIG. 1 is a side view of the machine; figure 2 - view of its top; FIG. 3 is a front view of it; FIG. side slider and comb; FIG. 5 - the same, top view.

In the front part of the bed, 5P (f. 1-3), a table was strengthened, in the middle of which steel strings 43 were pulled to impose a sheepskin combed by a comb 22 with teeth 24 connected to a slider 21, the latter being driven by a crank 10 Of the flywheel 28a.,

The comb moves back and forth along the table, whereby during the forward stroke the comb rises 6-10 cm upwards, and during the return stroke it drops onto the sheepskin. In order that the comb could not move the sheepskin from the table, per cm 42, which is clamped and retracted by the eccentric 33 using the levers 31, 34, 38, 40, 41 and 44.

The tooth 24 and the comb 22 have a rectangular cross section and are sharpened at an angle on all sides; the profile of the teeth is curved. The teeth are inserted from above into the comb 22 and secured by the bar 25 with the aid of four screws, so that, in the case of a broken tooth, it can be replaced with a new one. The teeth are arranged in two rows in a checkerboard pattern and must be ground in order to be easily cleaned from dust and hair. When combing cohesive sheepskins, it is necessary to adjust the teeth at different heights from the table, for which a tightening screw 20 is arranged, which, when screwed, rotates the comb 22 on axis 3, and consequently raises it to some

height.-,

The spring 2 located on the screw J serves to prevent the sheepskin from puncturing the teeth. The screw should be bent along a radius equal to the distance from the center of axis 3 to the center of the screw. Detail J9, together with the mechanism described above, is automatically raised and lowered, and at the same time the shooting of the wool from the teeth takes place, since the latter are

go through the holes located in the slider.

During the rotation of the flywheel 28, the crank 10 moves the rod 15 along the cast-iron sleeve 9, as a result of which the earring 5 draws one end of the lever 19 downwards; but since the latter rotates freely on the axis 18, the front end of the lever 9 rises upward with the comb fixed on it, and when the shoulder 16 reaches the rubber 12, the slider 21 begins to move forward. In the same way, the comb is lowered and the slide stroke (working) moves. Tube 8 serves for lubrication and at the same time for inserting the insert. Rubber rings 12 serve for the purpose that there was no strong knock when the machine is running. 30 and the eccentric 33, which, at the working stroke of the slide, with its convex part presses the roller 32, which is fixed to the lever at the end 31; the other end 5 of the lever moves the lever JS forward, which rotates the axis 47 and at the same time the lever 41, which by the lever 44 presses the sheepskin to the table. One side of the clamp, leather-trimmed, attached to the table. During the entire working stroke, the clamp is nahog

hold down; when idling (forward), the spring 36 returns the lever to its original position, and zazhm 42 also retreats from the table

The slider guides are strips 46, flattened at the bottom, and frame 39. The strips are bolted to the frame; the lubrication is made through the holes made in the halves 46. At the country of mission, the movement is transmitted through the pulley 28, the transfer of the belt from which to the idler pulley is made according to the principle of variable machines.

The subject matter of the invention.

Claims (2)

1. A machine for combing sheepskins, is different from the fact that the comb 24 is mounted on the axis 18 connected to the slide 21 and is brought into reciprocating and swinging motion with the help of the lever 19 of the earrings 5, the rod 15 in the slide 13 and connecting rod 10 from the flywheel 25. 2. In machines: e according to claim 1, applying a hide-holding clip 42, driven by means of levers 44, 40, 38 and 34 from an eccentric 30 on the drive shaft. with with - 22 21 Sv 1 "124e Yu.
