Description

The proposed skin treatment machine with the use of knife rolls, rollers pulling in and pressing the skin, is characterized in that the rollers pressing the skin are performed. Each, in the form of two sectors, for alternately pressing the skin to be treated to the blades. In order to obtain different thicknesses in different places of a single piece of leather, the working surface of the pressure rolls is made in the form of spiral segments. The working surface of the clamping rolls can also be made in the form of semi-circles. In order to feed the skin, a carousel of stele is installed in the machine, which can be lifted as it is removed from its skin by toothed racks from the shaft and descend along an inclined arc, and a pusher conveyor is used to push the skin to the skin shaft. The treated leather enters the lattice, and its transfer to the carrying conveyor is carried out by a shaft with knitting needles. Electromagnets are used for automatic switching on the conveyor.

In FIG. 1 is a food cut of the machine; FIG. 2 is a side view; FIG. 3 is a plan view; FIG. 4-lower part of the feeder; FIG. 5 is a view of the middle half from the side of the transverse vertical.: A cut along the line between the knife shafts; FIG. 6-movable bearing; FIG. 7-shaped clamp. 1st shafts. The machine is driven by a pulley 2 (Fig. 1), mounted on a transverse shaft 7. On the same shaft near the wall of the machine, a gear wheel is attached, coupled with a gear wheel sitting on the shaft 5, thanks to which the shaft. rotates in the opposite direction of the shaft. At the ends of the shaft 7, two pulleys 4 (FIG. 3) are attached, connected by passes with small pulleys 3 sitting on the shaft of the knife shaft 6. At the ends of shaft 3 sit D1 of pulley 7 connected with passes of smaller pulleys 8 sitting on the ends of the knife shaft 9 (Fig. 3). The direction of movement of the knife shafts 6 to 9 9 coincides with the movement of the shafts 7 and, and had) -, o: shaft 6 rotates in the direction opposite to the clockwise direction, and shaft 9 is clockwise. At one end of the shaft 3 (Fig. 3) sits a small gear 10, coupled with a large gear 11, on a common roller with which a bevel gear 72 (Fig. 1 and 3) is attached, coupled with a gear 75 and shaft 14. At the other end shaft 7 is reinforced with conical gear 15, coupled with

stubble 16, sitting on the cross roller 17 (ig. 1 and 3). The roller 77 rotates clockwise and rotates counterclockwise to the fnium roller 75 by means of gears 19. Both etiquer 77. and 18 are covered with rubber and skin coming in between them. At the ends of the roller 77, two gears 20 are reinforced (FIU. 3). Above the blade shafts 6 and 9 (Fig. 1) in bearings there are two two-suction rollers 27 and 22 serving to press the skin against the knives. At one end of the shaft 27, a gear 23 is fastened, coupled with a wedge 20 on the roller 77. At the opposite end of the roller 22 there is a gear 24 which is engaged with the second gear 29 of the roller 77. If the shaft 77 rotates clockwise, then both two-sector rollers 27 and 22 rotate counterclockwise. Both of these rollers make one revolution in 3-4 seconds.

The planing of the skin on the machine is as follows. The skin is fed from the left side between the rollers 17 w. 18 to that mommelt when the two-sector drum 22 buzt is turned by an empty quarter downwards, i.e. when the passage will be the most wide. As soon as the skin enters between the rollers 77 and J8, the angle of one sector of the roller 22 will press it against the knives, as a result, the planing process will immediately begin. Knives planing the skin, pull it back - while rollers 77 and 18 pull it forward; Thanks to this, all the second half is cut off with a knife shaft 6. The first half of the skin, which has entered the unprojected cushions, is pulled out by the knife shaft 9 under the pressure of a two-roll drum 27. At that moment, when the front end of the skin reaches the top of the knife shaft P, the sector of the roller 27 | 5net down and press it against the knives.

In view of the fact that the parts of the circle with which the sector shafts press the skin to the knives are not of the same radius, then where the radius is smaller, part of the skin goes thicker, and where the radius is large, it is vice versa. Prostrated leather from rollers 77 and 18 enters (FIG. 1) into rollers 25, which are selected, ascribed to the grille 26, from where it is pulled onto the conveyor with the spokes 27 (FIG. 3) attached to the shaft 2, which is rotated through Zubchatudo couple 2P from the shaft 7-.

The feeding mechanism has the following device. In the hollow column 30, the shaft I rotates (F.-ir. 1), to the upper end of which two triangular plates 32 and 33 are connected, connected at the corners with each other rod 3 and 34. Trill is worn on these rods (Fig. 3) site 35, one for each hundred of the triangle. These platforms can walk m rods 5 m up and down. Each of the pads is covered with 36 leather. On the platform 35, leather 7 is applied with piles. All this carousel: 1a, the system rotates around the shaft 31 counterclockwise and alternately feeds each platform to ours. To the branches of column 5 (9 an arc 3 is attached ((Fig. 4)), which delays the upper parts of the row; d (ok 36). To feed the skin into the machine, the comb 36 alternately engages with the hour; trenches that, rotating, raise the comb up, and with them, and the platform (Fig. 1 and 5). Above the carousel, along four gears 41, there are two chains 42 (Fig. 1) with rods 43 fixed in equal places in three places, on each of which the basement of the t6dkat # (flanges 1 and 3) are strengthened. The gears 41 rotate to the left, so that each pusher, below, goes to the car, on its way to 1 tom, closes one skin and directs it through the shaft 6 to the rollers 77 and 75. The reverse pushers 44 go through the top of those that go forward forward. On the shaft 3, a screw is fastened to the gear shaft 45, which sits on the vertical shaft 6 (flg. 1) , of which 4ipe3 serrated pair 47.48 slowly drives shaft 49.

On the very basis where the column 30 stands, there are two racks 50 (. 1 and 5) with bearings ,. in which the shaft 57 is rotated by the shaft 57, which, in turn, rotates the rollers 52, in turn, the screws 40 and 5P. Shaft 57 with pads 35 is set in motion as follows; on shaft 49 next to column 30 there is a worm to 53 (flg. 4) coupled to gear 54, sitting on a shaft with lower gear 55. Gear 55 clutch with gear 56, Ukeepl ZINA on the shaft 5 / EXT; the columns are not tight, but by means of elastic springs 57 (flg. 4) like a clock, so that gear 56 lays down to make some part of the revolution on the shaft, tensioning the spring. During the operation of the machine, the gear wheel 56 continuously rotates to the side counterclockwise. The shaft 31 is in place while the platform combs are held up by the ends of the arc 38, moreover: the spring 57 is twisted at this time. When the paddle rises above the ends of the arc, the pad, due to the elasticity of the spring 57, will rotate the carousel by one third of the range, and the spaced platform will move to the side and its place will be loaded. The elevated empty platform will lower - down along two inclined planes 58 and 59 of the arc 38 (Fig. 4), into which the canl and the comb are supported.

For the Tego to np: i turn the pad 5 n; There are two fixed walls of 6C above the pushers 44, above the carousel, and in order for pieces of skin to move the area do not fall, the intersection bars are filled with rigid platforms 57. The conveyor for transporting simple leather consists of two chains 62, running four teeth 63, mounted on shafts 64 and 65. H; a cut of the opposite chain links skipped rod 66, at the ends of which there are rollers moving along the rails 67 (Fig. 3); The conveyor belt is driven by gear 68 via a serrated sleeve 69, which is switched on and off at the right time by an electromagnetic: 1 tons a, c. The knife point is carried out by a rotating grinding stone with automatic feed. Below the knife 6, P (flg. 1 and 5) on square shafts 70, clamped in square sleeves, rotating their (the round part in the holes of the brackets 77 rotate the grinding stones 72. In the back of the bracket, the fork is fastened, entering into the thread channel, a lot of worm 73. Square shaft 70 rotates with chain 74 (fig. 2) thrown over small gear on shaft / and large gear 75 on shaft 70. Shaft 70 is connected with worm gear 73, 77 with gears 76, 77 so that np: i rotates the shaft 70 stone 72 and rotates and walks to both sides along the length of the shaft, Podsh picnikl sector rollers 27 and 22 are installed directly When the knives on shafts 6p9 are worn out, the skin will get thicker, in order to avoid what the knife shafts, and with them sharpened as the knives are stitched, are automatically and continuously fed upwards. frame 78 is reinforced (fig. 6), at the top of which there is a bearing 79, In this frame there is a smaller frame 80 with two bearings 81 and 82..-,

A screw 83 passes through the holes in their lower walls of both frames, and in the frame 78 there is an opening without cutting, and in the frame 80 with a cutter. The lower part of the screw 83 is screwed into the nut 84, ex: 1 the screw on both halves of the screw is opposite, so that when they turn the screen 83 to unscrew it from the nut 84, the screw shoulder lifts the frame 78, which at the same time rises in the frame 78 and frame 80. In the bearing 79, one end of the blade shaft rotates, in the bearing 81 is the shaft 70 of the sharpener, and in the bearing the 82 end of the screw is 73. Each wall has two such bearings on the inner side. During operation, the screw 83 rotates very slowly, so that the knife shafts will always be at the same distance from the sector.

Disturbance of distance could occur from a reduction in the sharpening itself, as a result of which the diameter of the blade shaft would increase. To eliminate this, the nut 5 is imad the outside of speech and is screwed into the gear 5. The nut 84 cannot rotate due to the protrusion 86 entering the longitudinal channel; when turning the gear 85, the nut 84 with its bearing system is equally raised or lowered.

The screws S3 rotate as follows: their: square ends go deeper down and fit into gears 87 (Fig. 1), driven by worms attached to shaft 88 (Fig. 5); the latter is rotated by gear 89, driven, in its center, by a worm 90, sitting on the shaft 49 (Fig. 1).

A characteristic feature of the proposed machine is the possibility of a simple ezhok on it from 5 inches to vershoks in a dll. When skinning leather from 5 to the tops, all parts of the machine are not changed. In the case of prodrozhka skin to the length of the tops, the following parts of it change:

1) other knife shafts with one compartment are inserted.

2) other pressure shafts are inserted (Fig. 7),

3) spacing 1n areas 35,

4) the entire feeder is pulled to the edge with a screw 9J,

5) the elevation speed of the platform 35 varies.

6) the role of the driver 53 goes to the screw 92, -7) the speed of rotation of the shaft 28 changes and the foot 93 is actuated, which serves to periodically delay the rotation of the shaft 2 (Fig. 3). The end of the foot 93 holds pin 95 on the shaft. The gear on the shaft 28 is worn in the same way as the gear 56 on the shaft 31 (Fig. 1). The eccentric PT periodically pushes off the foot 93, and the shaft 28, after turning, is again delayed. Shaft 28 stops are necessary. in order for larger skins to fit over the entire grille 26. Raised BEARINGS for inserting a knife shaft with new knives are lowered when the gears with handles 96 are attached. Shafts 6 VL 9 for insertion of new knives are removed — one through the pro, cut 97 , another through slot 98, the shavings fall into the cash registers 99, which, rotating, take them out.
