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

Embodiment Construction

[0042] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0043] Such as Figure 1 to Figure 14 Shown is a process for processing leather trimmed stitches for leather products, which uses a device for processing leather trimmed stitches for leather products. The device includes a workbench 1 and a clamping mechanism 2. The specific processing technology of the finished leather cutting and sewing thread processing device for leather product leather cutting and sewing thread processing is as follows:

[0044] S1. Leather laying: Lay the leather and the lower part of the pressing plate 23 and the clamping group 26 on the workbench 1 manually, and make the left end of the leather just below the pressing plate 23;

[0045] S2. Leather unilateral pressing: drive the vertical plate 22 to move downward through...

Abstract

The invention relates to a leather product leather cutting and sewing processing technology which uses a leather product leather cutting and sewing processing device. The leather product leather cutting and sewing processing device comprises a working table and a clamping and fixing mechanism, the working table is installed on the existing ground, and the clamping and fixing mechanism is arranged at the upper end of the working table. According to the leather product leather cutting and sewing processing technology, the multi-adjustment design concept is adopted for leather product leather cutting and sewing processing; the arranged clamping and fixing mechanism can clamp and fix the two side ends of leather and can also play a role in smoothing the leather to keep the optimal flatness of the leather, and then the overall cutting quality of the leather is improved; meanwhile, a rolling smoothing structure is adopted so that the probability of motion clamping stagnation of the structure can be reduced by generating rolling friction; and the whole device can also realize switching between a vertical leather cutting mode and a transverse leather cutting mode, so that the adaptation degree of the device to the leather cutting requirement is greatly improved.

Description

technical field [0001] The invention relates to the field of leather processing, in particular to a leather cutting and sewing thread processing technology for leather products. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain. The leather production process mainly includes waterworks operation, tanning process, leather blank production process, coating process, finished product cutting and sewing process, etc. The leather industry covers tanning, shoemaking, leather clothing, Main industries such as leather goods, fur and its products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories, have a high degree of upstream and downstream correlation,...
