Abstract

The inventive machine contains a skeleton, knife, grooved and clamping shafts, a gearbox of grooved and clamping shafts, the gearbox being differential and having cylindrical wheels with internal and external gears, satellites, a carrier, while one of the shafts (grooved or clamping) engaged with a carrier, and the other with an internal gear. 3 ill.

Description

The invention relates to mechanical processing and skinning technology, and in particular to machines for processing semi-finished leather in leather and fur production.

The aim of the invention is to expand technological capabilities by increasing the range of processed semi-finished products.

Figure 1 is a kinematic diagram of a mezdril machine; Fig. 2 is the same for chain coupling of a gearbox with grooved and pinch shafts; Fig. 3 is a transportation diagram of a semi-finished product.

The machine comprises a grooved shaft 1, a rubberized pressure shaft 2 mounted on a swinging frame 3, a differential gear 4, including a spur gear 5 with external gearing, a spur gear 6 with internal gearing and an associated gear gear or sprocket 7, gears 8, drove 9 and its associated gear or sprocket 10 to drive the grooved shaft through gear 11. Gear 4 through the output gear 7 and gear or sprocket 12 is connected to the pressure shaft 2. The grooved shaft 1, the pressure shaft 2 and the half ikat 13 through the drive pinion shafts and gear form a closed gear at fleshing knife Ba .lom 14. All parts of the machine are positioned on the frame 15, on the grooved shaft presser spring 16 is mounted.

Mezdrilna machine operates as follows.

In the initial position, the swinging frame is in the retracted position (the drive for bringing the frame in and out is not shown). Semi-finished product 13 is laid on the clamping shaft 2, the swinging frame 3 brings the clamping shaft 2 to the corrugated shaft 1, the knife shaft 14 and the process of mesentery begins.

In this case, the spring 16 provides the necessary force to press the shaft 1 against the shaft 2. According to the scheme shown in Fig. 1, the movement of the shafts 1 and 2 begins when the gear 12 engages with the gear 7 and when the gear drive 4 is turned on. shown in Fig. 2, the movement of the shafts 1 and 2 begins when one shaft approaches the other.

After processing the semifinished product 13, the frame 3 is retracted, the semifinished product is rotated or removed, and the curing process is repeated.

During operation of the machine, the wear of the clamping shaft 2 occurs to a greater extent than the wear of the corrugated shaft 1, and this leads to a change in the ratio of the angular velocities of the shafts 1 and 2 or to the appearance of slippage. The slip reduction is ensured by differential gear 4 by means of spur gears 5, 6 and carrier 9.
