Abstract

The invention relates to the field of leather processing and discloses an automatic leather tightening device. The automatic leather tightening device comprises a leather tightening moving component, a leather edge position identifying component, a leather pressing assembly and a leather horizontal moving and positioning component. The leather horizontal moving and positioning component is mounted on a rack and is guided through a guide rail. The leather edge position identifying component is arranged across the rack. The leather pressing assembly is composed of a power-losing electromagnet, clamping iron and double-arm mechanical hands. By the adoption of the automatic leather tightening device, it is guaranteed that the leather can be tightened and also can be conveyed to the next working unit. Compared with the prior art, the automatic leather tightening device has the beneficial effects that fast, uniform and automatic tightening of the leather is achieved, the labor cost is saved, and the leather processing quality is improved.

Description

technical field [0001] The invention relates to the field of leather manufacturing and processing, in particular to a leather stretching device. Background technique [0002] With the development of science and technology and the expansion of the leather market, leather technology has also developed rapidly. The stretcher drying process in the tanning process is a key link in the tanning process. The current stretching equipment is mainly to manually pave the leather and manually install clips on the edge of the leather. The clips are fixed on two plates that can move relatively, and the plates move relatively to stretch the leather. [0003] The current stretching device mainly has the following defects: [0004] The current stretching device requires 5-6 workers to spread the leather on the stretching board, and manually install 80-100 clips on the edge of the leather. The production efficiency is low, the labor intensity is high, and the quality of the leather The qual...
