A kind of processing technology of leather material cutting and sewing thread

Abstract

The invention relates to a process for processing leather trimming stitches for leather products, which uses a leather trimming stitching processing device for leather products. The leather trimming stitching processing device includes a workbench and a clamping mechanism. The workbench is installed on the existing ground, and the upper end of the workbench is provided with a clamping mechanism. The present invention adopts a multi-adjustment design concept for leather cutting and suture processing. The implementation of the clamping treatment can also smooth the leather to maintain the best flatness of the leather, thereby improving the overall cutting quality of the leather. At the same time, the rolling and smoothing structure is adopted to reduce the appearance of the structure by generating rolling friction The probability of motion jamming is reduced, and the device as a whole can also realize the conversion between the dual modes of vertically cutting leather and horizontally cutting leather, thereby greatly improving the adaptability of the device to leather cutting requirements.

Description

technical field [0001] The invention relates to the field of leather processing, in particular to a processing technology for cutting and stitching the leather of leather products. Background technique [0002] Leather is a denatured and non-perishable animal skin obtained by physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Texture and luster and feel comfortable. The production process of leather mainly includes water plant operation, tanning process, leather blank production process, coating process, finished product cutting and sewing process, etc. The leather industry covers leather making, shoe making, leather clothing, Main industries such as leather goods, furs and their products, as well as supporting industries such as leather chemical industry, leather hardware, leather machinery, accessories, etc., have a high degree of upstream and downstream linkages, rely on ...

AI Technical Summary

Problems solved by technology

[0003] 1. The pressing and limiting strength of the leather in the laying state is relatively low, so that it is easy to shift when cutting, and there are uneven laying parts of the leather, and the cutting quality of this part is low. At the same time, the device used Leather can only be cut in one direction;

[0004] 2. The vicinity of the leather cutting point is prone to large depressions due to no external pressure. When using a manual hand-held cutter for cutting work, the inclination angle of the cutter is maintained at a low degree and there is a deviation in the adjustment of the entry angle. At the same time, the cutting knife is also prone to deflection, resulting in reduced cutting quality
