Leather rapid circulating dyeing drum

Abstract

The invention discloses a leather rapid circulating dyeing drum which comprises a bottom plate; a dyeing box and a driving box are fixedly connected to the top of the bottom plate; support columns are fixedly connected to both sides of the dyeing box; the bottom ends of the support columns are fixedly connected to the top of the bottom plate; a liquid injection pipe communicates with the top of the dyeing box; a liquid discharge pipe communicates with the bottom of the dyeing box; a fixing block is fixedly connected to one side on the inner wall of the dyeing box through a support rod; and a central shaft is in sliding connection with one side of the fixing block. According to the leather rapid circulating dyeing drum, the problem that leather dyeing in the prior art usually adopts dyeing barrels or dyeing drums of single structures is solved; the dyeing time is shortened; the work efficiency is improved; later normal use and production of leather are guaranteed; the condition that the conventional dyeing equipment is single in structure is changed; the designability of the dyeing equipment is improved; the structure is simple; the operation is complex; and users can use the leather rapid circulating dyeing drum more conveniently.

Description

technical field [0001] The invention relates to the technical field of leather production, in particular to a leather fast circulation dyeing drum. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] Dyeing is dyeing, also known as coloring, which refers to the use of chemical or other methods to affect the substance itself to make it colored.
