Graded tanning machine for leather

Abstract

The invention relates to the technical field of leather processing equipment and discloses a graded tanning machine for leather. The graded tanning machine for leather comprises a base, wherein an annular groove is formed in the middle of the top end of the base; four rollers are glidingly connected with the two sides of the bottom end in the annular groove; every two of the four rollers constitute one group and are distributed on the two sides of the bottom end in the annular groove respectively, iron plates are fixedly connected with the top ends of the two groups of the rollers, and short rods are fixedly connected with middles of the top ends of the iron plates respectively. According to the graded tanning machine for leather, under matched usage of annular racks, a gear, an asynchronous motor and structures, animal fur on clamping devices can rotate in a soaking tank with support rods and then is dehydrated, and furthermore, water on the animal fur cannot be spilled out of the soaking tank, so that dehydration of the animal fur can be realized by the graded tanning machine for leather.

Description

technical field [0001] The invention relates to the technical field of leather processing equipment, in particular to a graded tanning machine for leather. Background technique [0002] The physical and chemical process of turning raw hide into leather through tanning agents is called tanning. Tanning is an important process in leather and fur processing. Different tanning agents produce different tanning methods, such as the most commonly used chrome for light leather. Tanning agent tanning is called chrome tanning. [0003] In order to make raw hides into leather, a series of preparatory processes such as soaking, dehairing, liming, softening and pickling are usually used in tanning machines. However, traditional tanning machines cannot dehydrate raw hides after soaking, nor can they Before processing, the required two solutions are adjusted in proportion, and the processed fur cannot be graded, so a leather graded tanning machine is introduced. [0004] Aiming at the de...
