SU20254A1 - Machine for cutting wool from the skins - Google Patents

Description

The invention relates to combers used in hair clippers of comb knives with detachable grooved combs driven by a mechanical drive. In the proposed machine, the skin intended for cutting the wool is provided with the help of the spring table and the cushion under the detachable comb knives, driven by separate drives, giving one of the knives the possibility of longitudinal movement through the connecting rod and the fist washer from the main shaft installed perpendicularly to its movement and the other is transverse displacement from a washer with a fist cutout mounted on the same shaft.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2- shaft view with rear end; FIG. 3 is a side view of the shaft in FIG. 2; FIG. 4-cross-section of a modified machine; FIG. 5 is a side view of the cutting part of the machine shown in FIG. four; FIG. 6 shows the arrangement of the shafts of the machine shown in FIG. four.

In the proposed machine, the maintenance and stretching of the skins to be cut are done by means of the table II, which is installed

on the spring HI, and the H and H rollers driven by the transmission from the transmission. The H roller, the axis of which is mounted in the stationary bearings C of the bed, has a grooved surface that contributes to a better capture of the skins. The axis of the roller K is installed in the movable bearings C2, pressed by the spring Cs in the direction of the roller and for better pressing to the last roller K. A cutting comb knives 1 and BI are located above the table I. Above the knives, a quick rotary brush L {, whose purpose is to comb and stretch the hair of a skin, setting the latter in a strained position and dropping the cut wool, is established. In order to set the sandpaper in the machine, the brush and the cutting knives are retracted to the right of the one shown in FIG. 1 working position The lower comb knife 5j consists of separate teeth, plates, screwed to the bar B. Above the lower knife BI is placed the upper comb knife 1 attached with screws to the bar A, the contact of the flat blades with each other occurs only with the edges of their surfaces, due to being in the middle part

recess knives to reduce friction when working and intended to accumulate dirt released from the skins, removed through the corresponding holes in the knives. The plates Ld and 2 with the knives L and D fixed on them are attached to the rods Lz and Bz, located above and below B, connecting the beds P and A of the machine, respectively. The adjustment of the installation of the bars Lo and B on the connecting rods is carried out by means of stop screws (not shown in the drawing). In frame B, there are guide slots for the respective tides of the connecting rods. On frame B, set the sleeve for the drive shaft O with a pulley rotated by the transmission. Drive shafts are placed on the shaft, transmitting the movement to the connecting rods. The cam washer Oi with the ring O put on it rotates in the slot of the lower connecting rod B, together with the longitudinal movement of the lower knife Sj. The washer Oz has a cam recess 0 (Fig. 2), in which the rollers of the rod Lz enter the transverse movement of the upper knife AI. The frame B and the connecting rod C are moved in the slots of the frame G. The pressure adjustment of the cutting knives is made by means of abutting the springs a, b on the connecting rods attached to the bolts b and tightened with c. The bolts are passed through the corresponding slots in the connecting rods and frame B. The position of the frame Г, Г is adjusted by height with screws Z), / 2B to the modified machine (Fig. 4-6) from the drive shaft, rotation is transmitted to shaft C and eccentric E mounted on it, which transverse movement a connecting rod PI, to which the upper cutting knives are attached. The lower knives are fixed on the connecting rod P, which receives a longitudinal movement from the eccentric 9i, which is on the shaft Zf ,, rotating from the drive shaft by means of the shaft C and a pair of bevel gears W and W, the cutting knives are made of separate plates into several teeth each . The plates I of the lower knives are attached directly to the connecting rod p. The blades HI of the upper blades are inserted into the corresponding sockets in the connecting rod PI by means of springs n placed in special sockets above the upper blades and used to press the latter against the lower shearing blades. The amount of pressure that presses the knives is adjusted by screws in, in, passed through the upper part of the bed C into the plates of the upper knives, the springs HI are inserted, protecting the plates from escaping in the event of a foreign body.

The subject of the patent.

1.Mashchina for cutting wool from skins using comb-shaped knives, driven from a mechanical drive, characterized in that, in addition to drive Oz, in the form of a washer for the upper comb-knife, the driving washer Oi for the lower knife is used.

2. The form of execution of the machine mentioned in p. 1, characterized in that in order to give the lower knife a longitudinal movement, the drive shaft O is installed perpendicular to this movement and coupled to the connecting rod. With this knife, the fist washer Oj, while for the upper the knife of transverse movement to the movement of the lower knife, the upper knife is articulated with the shaft O by means of a washer Oz with a fist notch O.

3.When marked in p.p. 1 and 2, the use of the spring table I and the adjustable roller I.

4. The form of implementation of the above in pp. 1 and 2 machines, characterized with the use for driving comb-blades of two separate valoses C, C with eccentric washers E, 9i. jointed with the help of connecting rods with knives. l Fig Q, ..... i-i у4 -, -.- hh .. „±; h | ;,: -: -:, -: ,, .. ..-- h -.
