Description

Leather stretching device for leather processing Technical Field The utility model relates to the technical field of stretching equipment, in particular to a leather stretching device for leather processing. Background The leather is an animal skin which is obtained by physical and chemical processing such as dehairing and tanning and is not easy to rot, and various performance tests are required to be carried out on the leather in the production and processing process of the leather, such as tensile performance tests are carried out on the leather by using tensile equipment, and whether the performances such as tensile strength, elongation, tearing strength and the like of the leather are qualified or not is determined. The existing leather stretching equipment is mainly characterized in that leather is fixed on two clamps in the use process, then experimental parameters are set through a controller, a driving column drives the corresponding clamp to move and stretches clamped leather, and a load sensor and a displacement measuring mechanism inside the driving column monitor and record key performance indexes such as deformation, strength, elasticity and the like of a leather sample in real time while stretching. However, the broken leather may be broken in the process of being stretched, so that the broken leather is rebounded and collides with staff, and the staff is injured in the process of being pulled out by the rebounded leather, thereby affecting the working safety of the staff.
