Technical Field

The invention belongs to the field of leather processing, and particularly relates to a double-roller leather processing system.

Background

The leather is animal skin which is obtained by physical and chemical processing such as unhairing, tanning and the like and is denatured and not easy to rot, and is widely used in daily life appliances of people due to good physical and chemical properties such as air permeability, corrosion resistance, softness, tear resistance, bending resistance and the like.

In the production process of leather, in order to facilitate the operation of later processes and prevent the oil stain phenomenon of the finished leather, the fat in the hypodermis layer, epidermis layer and dermis layer of the raw leather is generally removed.

Rawhide degrease generally divide into mechanical method and chemical method, wherein, the mechanical method generally destroys free fat and sebaceous gland through the mode of rolling, at present, mostly adopt the extruded mode of compression roller to go on, however, because the fat is more in the raw skin, at the extruded in-process of compression roller, a large amount of fat is piled up easily in the front side of compression roller, bring great resistance for the extrusion of compression roller, if the pressure that the compression roller was applyed is too big, again easily with the fat compaction, be unfavorable for the discharge of fat more, thereby lead to whole degreasing process inefficiency, the degreasing effect is not good.

To this end, we propose a two-roll leather processing system to solve the above problems.

Disclosure of Invention

The invention aims to provide a double-roller leather processing system with high degreasing efficiency and good effect, aiming at the problems of low fat removal efficiency and poor effect of the existing leather processing device.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a two roller leather processing system, includes the base, the upper end fixedly connected with mount of base, the lower extreme of mount is through a plurality of pneumatic cylinder fixedly connected with limiting plates, the limiting plate lower extreme passes through connecting strip fixedly connected with fixed plate, sliding connection has two sliding plates between limiting plate and the fixed plate, two fixedly connected with elastic component between the sliding plate, the both sides of fixed plate are all rotated and are connected with the pivot, the equal fixedly connected with dwang in both ends of pivot is connected at same root rotate between two dwang of pivot upper end and be connected with the compression roller, the upper end of dwang is rotated and is connected with the guide pulley, the guide pulley contacts with the lateral wall.

In the above-mentioned two-roll leather processing system, the elastic member is a plurality of return springs, and the plurality of return springs are fixedly connected between the two sliding plates in parallel.

In foretell two roller leather processing systems, the lower extreme fixedly connected with permanent magnetism board of fixed plate, be equipped with the cavity in the base, the upper end array of cavity has a plurality of hitting holes, hit the downthehole magnetic batting that is equipped with, the homopolar repulsion between batting and the permanent magnetism board, the batting passes through vibrating spring and the bottom fixed connection of cavity.

In the above two-roll leather processing system, the elastic member is an elastic air bag, the elastic air bag is fixed between the two sliding plates, and the elastic air bag stretches along the sliding direction of the sliding plates.

In the above-mentioned two roller leather processing system, the last one-way feed liquor pipe and the one-way fluid-discharge tube of being connected with of elasticity gasbag, one-way feed liquor pipe is used for supplementing the degreaser, the lower extreme of fixed plate is fixed with the hydrojet pipe through the connecting rod, the lower extreme fixedly connected with one row of nozzles of hydrojet pipe, one-way fluid-discharge tube and hydrojet pipe intercommunication.

Compared with the prior art, the double-roller leather processing system has the advantages that:

1. according to the invention, the two compression rollers are arranged, and when the grease-removing machine is used, the two compression rollers are respectively extruded towards two sides, so that on one hand, the accumulation of fat can be reduced, the resistance of the compression rollers in the rolling process can be reduced, on the other hand, the grease-removing efficiency can be exponentially improved, and the processing period can be shortened.

2. According to the invention, the elastic potential energy is stored by arranging the vibration spring, and after rolling operation is completed, the vibration spring can release the elastic potential energy, so that the hitting ball can continuously vibrate in the vertical direction, the raw skin can be knocked at multiple points, and the discharge of free fat can be accelerated.

3. According to the invention, by arranging the elastic air bag, the degreasing agent can be automatically sprayed while the raw hide is rolled, and the degreasing of the raw hide can be better realized by utilizing a chemical and mechanical combination mode.
