Problems solved by technology

[0004] It is obvious that using existing processing methods to sew and trim leather materials has the following disadvantages: 1. The sewing and trimming are carried out in two processes, and the production efficiency is low; 2. The trimming is completed by simple machinery, and some irregular shapes The finished product can only be done by hand, which is labor-intensive and time-consuming, and the production efficiency is low, so it is not suitable for mass production; 3. The quality of trimming cannot be guaranteed, and waste products are prone to occur

Abstract

This invention relates to a industrial stitching scissel equipment. It can do the scissel when stitching leather. It is a kind of stitching scissel frock that includes the industrial solid bowl type sewing machine that can sew the thick material. On the suture of the head of the machine wet big press foot, small presser foot and pins, and pin plate on the bottom. The features are that a cutting knife is fixed on the bottom of the big presser. The cutting knife is parallel to the pin moving route of the pins, and it is at the interior of the pins, the orientation of the knife edge is reverse to the feeding orienation. The cannal of lowering of roll is set on the pin plate, the cannel of lowering of roll is on the right inferior of the cutting knife.

Description

technical field [0001] The invention relates to an industrial stitching and trimming device, which is specially used for processing leather materials, and can complete the trimming process while stitching the leather. Background technique [0002] With the improvement of people's living standards, various leather materials are used more and more widely, and various whole leather or foreskin products have appeared. Generally speaking, the processing of these leather products has to go through processes such as blanking, sewing, and trimming. Among them, the trimming process is often the last process in the entire product manufacturing process, and it is carried out immediately after the sewing process. Therefore, , The quality of trimming is not only directly reflected in the appearance of the product, but also reflects the processing technology level of the enterprise to a certain extent. If the trimming quality does not meet the requirements, it will destroy the beauty of ...
