Leather liming device

Abstract

The invention discloses a leather liming device. The device is characterized in that supporting frames are arranged at the two ends of a base, shaft holes are formed in the supporting frames, a limingbarrel is a cylindrical barrel, a rotating shaft is arranged at the two end faces of the liming barrel, the axis of the rotating shaft coincides with the axis of the liming barrel, the liming barrelis arranged on the supporting frames through cooperation of the rotating shaft and a shaft hole, the axis of the liming barrel is parallel to the base, a feeding gate, a liming barrel and a drug inletare formed in the side face of the liming barrel, a drive motor is connected to the rotating shaft, a water removal clamp is arranged on the feeding gate of the liming barrel, and comprises a lower supporting plate and an upper clamping plate, one side of the lower supporting plate is connected with the edge of a feeding opening, baffles are arranged on the other sides of the lower supporting plate, and the upper clamping plate can be arranged on the lower supporting plate in a lifting manner. The leather liming device can automatically rotate and stir, putting in and taking out of raw material leather can be facilitated, drug can be conveniently added, sewage can be conveniently drained, the consumed time of the liming procedure can be shortened, manpower is saved, and environment sanitation is ensured.

Description

technical field [0001] The invention belongs to the field of leather manufacturing devices, and more specifically relates to a leather liming device. Background technique [0002] Liming is an important process in the leather manufacturing process. It is an operation that uses a certain concentration of lime water emulsion to increase the weight, thicken, and slightly shorten the length of the tanning raw hide after soaking in water, but the area hardly changes. The purpose of liming is to remove the fibrous interstitium in the skin, weaken the connection between the hair, epidermis and dermis, modify the elastic fiber, destroy the muscle tissue, and facilitate the effect of other materials on the skin in the subsequent process, and at the same time saponify the oil in the bare skin and remove the skin. Part of the oil in the skin can degrease to a certain extent, and can open the secondary bonds of the collagen part, so that the collagen fibers can be properly loosened and ...

AI Technical Summary

Problems solved by technology

The traditional liming process uses a concrete tank or other large container as a carrying device, puts the raw skin and corresponding chemicals into it together, and uses manual stirring for liming. This liming method is inefficient, time-consuming, and wastes manpower. , and the sewage is difficult to discharge, and the sanitation environment is poor
