Anti-winding structure during leather cleaning treatment

Abstract

The invention provides an anti-winding structure during leather cleaning treatment, and aims at solving the problem of how to improve the adequate contact between leather and a cleaning liquid. The anti-winding structure is used for a drum body, wherein the drum body comprises an inner drum body. The anti-winding structure comprises a plurality of pile heads sand a plurality of drum balls which are arranged in the inner drum body; the pile heads are fixed to the inner wall of the inner drum body; the pile heads are different in length and thickness, and the pile heads define an undulant impactsurface; the drum balls and the leather are mixed together and capable of moving in the inner drum body; the pile heads are vertical to the inner wall of the inner drum body, the transversal sectionof the inner drum body is octagonal, a support plate is arranged on each surface of the inner drum body, each support plate is connected with the inner wall of the inner drum body through an elastic element, a through hole enabling the corresponding pile head to penetrate through is formed in each support plate, and each support plate is capable of longitudinally sliding on the corresponding pilehead; and when the elastic elements are not compressed, the impact surface is located between the support plates and the inner wall of the inner drum body, and when the elastic elements are compressed, the support plates are located between the impact surface and the inner wall of the inner drum body.

Description

technical field [0001] The invention belongs to the technical field of leather processing and relates to an anti-winding structure during leather cleaning. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tannin. It has natural grain and luster, and feels comfortable. It is used in leather applications such as household leather. [0003] A drum is a rotary device in which raw hides are turned inside (such as for washing, pickling, tanning, dyeing) or for cleaning furs inside (by turning together with fine sawdust) during the tanning process. It is an important equipment widely used in tanneries , when driven by the motor, the leather in the drum is subject to mechanical actions such as bending, stretching, smashing, stirring, etc., which speeds up the chemical reaction process and changes the physical properties of the leather. The application range of the drum covers mo...
