Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leather processing, in particular to a leather processing tool. Background Art
[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processing such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster and feels comfortable. The leather industry covers main industries such as leather making, shoemaking, leather clothing, leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. It has a high degree of correlation between upstream and downstream, relies on market pull, has evergreen products, and integrates the characteristics of earning foreign exchange, enriching the people, and providing employment.
[0003] The leather processing method is a method of processing animal skins into mature skins for making leather products. The raw animal skins not only contain oil and hair fibers, but also become hard after drying. Therefore, in order to turn animal skins into leather that can be used by people, it is necessary to first carry out preparatory processes such as scraping fat and fleshing, dehairing, liming, deliming, softening, and pickling. Then the bare skins are tanned with tannic acid. During the tanning process, tannic acid not only replaces the moisture in the raw skins, but also combines with the collagen fibers of the raw skins to become leather that is heat-resistant, resistant to hydrolysis, and anti-microbial.
[0004] Currently, leather processing equipment on the market needs to dye the leather, and tanning operations are required before and after the leather is dyed. However, the machine tanning of the leather is basically one-way tanning, which causes the leather to warp after drying, affecting the quality of the leather. After the leather is dyed and kneaded, it needs to be cut. The efficiency of manual cutting is very slow. Machine cutting cannot adjust the size at any time and is prone to burrs, requiring manual subsequent adjustments. Utility Model Content
