Description

A kind of waste leather crushing device

Technical field

The utility model relates to the field of leather product recycling, and in particular to a waste leather crushing device.

Background technique

Genuine leather is animal skin that has been denatured and non-perishable through physical and chemical processing such as hair removal and tanning. In order to achieve resource recycling and comply with the international ecological concept of green and environmental protection, recycled leather has been recognized by many companies and widely used in products. Recycled leather is a product obtained by crushing waste genuine leather into leather fibers of a certain size and mixing them with rubber and resin.

Crushing is a very important part of the recycled leather manufacturing process. A crusher is usually used to crush waste leather. During the crushing process, due to the relatively small crushing size requirements, when the feeding amount is too large or the feeding speed is too fast, it will easily cause the crusher to work under a high load. A large amount of materials will be torn and squeezed together by the cutter, which will cause This causes the crusher to have stuffing problems and reduces the crusher's working efficiency.
