Description

Technical Field

[0001] This utility model belongs to the field of leather processing technology, specifically, it relates to a device for softening cowhide. Background Technology

[0002] After wet treatment or high-pressure embossing and ironing, the leather becomes hard to the touch. Before proceeding to the next process, the leather needs to be softened by tumbling, squeezing, and kneading in a tumbling drum. This process usually takes several hours. Rubber balls or soap pods are often added to the drum to help soften the leather. Sometimes, some wax is added to increase the shine of the leather surface. Tumbling can promote the softening of the leather or give the grain a unique tumbling pattern. This method is suitable for processing soft leather. During this process, it is inconvenient to observe the condition of the leather inside, and it is also impossible to adjust and add chemicals in time according to the condition of the leather.
