Description

Machines for capturing bristles from pigskins pretreated by chemical means, equipped with a spring-loaded roller, interacting with a moving surface, used for breaking the bristles by friction, and pulling off the cheekbone belt conveyor, are already known.

The proposed mask has the peculiarity that the surface interacting with the spring-loaded roller is made in the form of a shaft, which is pressed against the roller by an eccentric and lifted to fill the cheek pads.

In the drawings of FIG. 1 shows a front view of a machine in an exemplary form of its implementation; FIG. 2 is a top view of the machine of FIG. 1, and FIG. 13 is a cross-section of the machine of FIG. one.

The machine consists of a lower horizontal roller / supplied with a grooved notch and interacting with it, oppositely from the middle of the corrugated upper shaft 2. The roller bearings / are passed through their vertical slots of frames 3, 4, 5. The roller U is made spring-loaded and supported along length using three half-bearings 6, 7.8.

Each of these semi-fittings has a socket for the stem 5 with a cup 10 at the bottom end, an open bottom and an embracing rubber shock-absorbing washer 11 supported in the cup by a chanboy 12 with a jack for the pressure screw 13, wrapped in the beam of the traverse 14 mounted on the columns 16 to link to m 15 frames, 4 cars. The stem of each of the half bearings passes between the connections 15.

To transmit the rotation, the roller / from the electric motor 17 serves as a leather with a brush 18, coupled with the gear 19 of the intermediate roller 20, the gear 21 of which is coupled with the gear 22 of the roller 1.

The shaft 2, which interconnects from above with the bristles of the skin, filled with bakhtarma on the roller /, is provided at the ends with pins mounted in movable bearings guided by the vertical cuts of the frames 4. It rotates in the direction opposite to the direction of rotation of the roller /, ery niecTepCH 23, 24. Rings 28 of shaft 2 are cruelly connected

with a flat 25, which has a slot for the roller 26 on top, the bearings of which are rigidly fixed in the frames 3, 4, 5. The roller 26 is equipped with two eccentrics 27, pressing the shaft 2 against the roller / through the rings 55, worn loosely on the axle shaft 2. Each slot of the plates 25 on top is blocked by a jumper 29 with a roller 30 lying in the plane of eccentrics 27. Gear 31 is loosely seated on a roller 26 with a cam 32 at the end of the sleeve allowing clutch 33, sliding along the key of the roller 26 from the fork 34, switching handle 35 roller 26. This knob is rotated. It is mounted on The shaft 36 of the rod 37 connecting the frames 4, 5. The gear 3 / is engaged with the gear 38 of the lower roller /, the insignificant movements of which within the deformations of the rubber washers 11 of the semi-bearings 6, 7, 8 do not exceed 5 mm, which does not affect the gears 38 and 31.

The number of revolutions of the roller / shaft 2 is the same, but the diameter of the shaft 2 is somewhat larger. The grooved notch of the roller 1 prevents the skins from slipping over it when the bristles of the billows 2 are pulled from it.

The interaction of the eccentrics 27 of the roller 26 with the rollers 30 of the lintels 29 of the plates 25 causes the latter to be lifted by the rings 28 for dressing the skin, i.e. its bristles over the roller.

Subject and title

A machine for shooting bristles from pigskins, chemically pretreated, provided with a spring-loaded roller, interacting with a moving surface, used for breaking the bristles by friction, and taking off the skin with a conveyor belt, characterized in that the surface interacting with the spring-loaded roller is in the shape of a shaft pressed to the roller with an eccentric and lifted to fill the hides.
