Description

Technical Field

[0001] The utility model relates to the technical field of leather product production, and particularly relates to a cutting device for leather product production. Background Technique

[0002] Leather is the animal skin that has been denatured and is not easily decayed through physical and chemical processes such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space, with a special grain layer on its surface, having natural grain patterns and luster, and a comfortable feel.

[0003] However, the existing leather cutting devices have obvious inconveniences in pressing and positioning the leather to be cut, which has become one of the key factors restricting the improvement of the production efficiency and quality of leather products. During the cutting process, the leather may move or deform because it is not fully pressed, which will not only lead to a decrease in cutting accuracy but also may cause waste of leather. Therefore, we need to propose a cutting device for leather product production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cutting device for leather product production, aiming to solve the problem that during the cutting process in the prior art, the leather may move or deform because it is not fully pressed, which will not only lead to a decrease in cutting accuracy but also may cause waste of leather.
