Abstract

Usage: the invention relates to light industry, and more particularly to the processing and dressing of hides, and can be used to process fur skins. SUMMARY OF THE INVENTION: A fur skin breaking machine comprises a conveying device, knife drums mounted perpendicular to the conveying device, support plates, each of which is located under the respective knife drum to form a gap, and means for changing this gap. The transporting device is made in the form of supply and discharge conveyors and a conveyor for holding and moving the skins during processing. The latter is made in the form of a wheel with a drive and a wedge groove on the outer surface of the volume and a clamping mechanism, consisting of a block with axes located on it equidistant to the wheel rim, on which spring-loaded rocking units are movably mounted with rollers placed in the wedge groove of the wheel. The inlet and outlet conveyors are pivotally mounted on the uprights and contact the moving part with the wheel. Knife center drums are located in one plane. 1 s.p. f-ly, 4 ill. cl

Description

The invention relates to light industry, and more particularly to the processing and dressing of hides, and can be used to process fur skins.

The aim of the present invention is to maintain the quality of fur hides during the breaking process and to increase the percentage of yield of suitable hides.

Figure 1 is a kinematic diagram of a fur-skin breaking machine; figure 2 is a General view of the conveying device; Fig. 3 - presses the skins with rollers and transfers motion from the conveyor wheel to the inlet and outlet conveyors (section AA in Fig. 2); Fig. 4 is a schematic diagram of a skinning machine.

The machine consists of a welded metal frame (not shown), two centering knife drums 1, 2, an inlet conveyor 3, a conveyor 4 for holding and moving the skins during processing, an outlet conveyor 5, a supporting web 6. Inlet and outlet conveyors made in the form of V-belt drives.

A flexible inextensible support web 6 oscillates from the drive 7 in the direction of the breaker drum to press the skin during the breaking process. The required clamping force is set

by means of a spring-loaded link linking the flexible support web and the drive.

Knife drums 1, 2 receive rotation from individual electric motors 8, 9 with a power of 3 kW by means of V-belt drives 10, 11.

The conveyor drive for holding and moving the skins during processing is carried out from an individual planetary gear motor 12 with a power of 0.55 kW, using a chain transmission.

The conveyor for holding and moving the skins during processing 5 consists of a conveyor wheel 13 and a clamping mechanism 14. The clamping mechanism 14, in turn, consists of a block 15 with axles 16 located on it equidistant to the wheel rim, on which spring-loaded rocking chairs 17 with rollers are movably mounted eighteen.

The conveyors 3 leading and 5 leading 5 are rotatably mounted on the posts 19 and the spring 20 presses the moving part of the conveyor (pulley) 21 to the wheel rim 13.

The fur skin 22 is laid on the feed conveyor 3 with the skin cloth up and as it approaches the working area, the skin 22 is sandwiched between the conveyor wheel 13 and the rollers 18 of the pressure mechanism 14.

The skin is treated with knife drums. In the zone of impact of the knife drums, a flexible, inextensible support web is applied, which performs oscillatory motion to provide the necessary clamping of the skin during the breaking process. After leaving the working area, the skins are freed from snapping between the conveyor wheel 13 and the rollers 18 of the presser mechanism 14 and are removed from the machine via the discharge conveyor 5.

The feed and discharge conveyors are driven from the inner rim of the conveyor wheel, and the pulley diameters are designed so that the linear speed of the feed conveyor 3 is slightly less than the linear speed of the conveyor wheel 13, and

the linear velocity of the discharge conveyor is slightly higher than the linear velocity

transporting wheel, which allows

avoid skin retardation and formation

folds on it.

Thus, the use of the proposed machine for breaking fur hides allows you to maintain the quality of the fur in the process of breaking and increase the percentage of yield of suitable hides, because the pressure conveyor wheel provides better skin retention due to the rigidity of the structure and the creation of a reliable labyrinth, and the location of the knife alignment drums in one plane reduced the lateral force on the conveyor device, which prevents the skin from being pulled out of pinching due to balancing the forces acting on

skin during processing.

Claims (2)

SUMMARY OF THE INVENTION 1. A fur skin breaking machine comprising a conveying device, spring-loaded rocking chairs with rollers, knife drums mounted perpendicular to the conveying device, support plates, each of which is located under the corresponding knife drum to form a gap, and means for changing this gap, characterized in that. that, in order to maintain the quality of the fur hides during the breaking process and increase the percentage of yield of suitable hides, the conveying device is made in the form of a conveyor for holding and moving the skins during processing, which is made in the form of a wheel with a drive and a wedge groove on the outer surface the rim and the equidistant wheel rim of the movably mounted spring-loaded rocking chairs with rollers located in the wedge groove of the wheel, and the feed and discharge conveyors. 2. The machine according to claim 1, with the proviso that the feed and discharge conveyors are pivotally mounted on the bed and are mounted so that the movable part contacts the wheel.
