Method for dividing leather to strips

Abstract

This invention relates to leather cutting method, particular for cutting leather into belt as long as possible. The etechincal scheme is the use of spiral of Archimedes edge which is fixed on a base-plate to form an edge mould. The mould is equipped on a puncher. During operation, the cutting machine (the puncher) pressure the leather to finish the cutting operation for belt as long as possible. It has advantages of: high efficiency, high quality, and less waste.

Description

Technical field: [0001] The invention relates to the technical field of leather cutting technology, in particular to a method for slitting leather. Background technique: [0002] In the tanning industry, there are usually several ways to cut leather strips as follows: the first is to use a disc-type slitting machine to slit, see the attached figure 1 , which is a structural schematic diagram of a disc type slitting machine, wherein: including a feed shaft 62, a knife shaft 63 and a blade 64 evenly distributed and fixed on the knife shaft 63, the leather 61 is formed by the knife shaft 62 and the feed shaft 62, the leather 61 is cut into strips according to the distance between the blades 64 by the circular blade 64. This kind of equipment can cut and shape many strips of leather at the same time, and is currently the most commonly used leather stripping equipment. The patent No. is: also disclose a kind of utility model patent of " leather cutting machine " in the Chinese ...

AI Technical Summary

Problems solved by technology

Although this equipment can cut many strips of leather at one time, because it cuts a piece of leather into several strips at the same time, the length of the strips of leather it cuts is limited by the diameter of the leather, and it cannot cut longer strips. shaped leather

The second method is to use single-knife or multi-knife cutting. This method also cannot form relatively long strips of leather, and cutting leather in this way will result in a lot of leftovers, resulting in great waste.

The third way is as attached figure 2 As shown, its concrete method is that leather 71 rotates at a constant speed on the one hand, and on the other hand does a linear motion from the center point to the direction of the knife edge. When passing through the blade 72, the leather is cut into strips by the blade 72. Although this method can cut long Strips of leather material, but its efficiency is too low, and the quality of processing is not stable

[0003] It can be seen from the above that although the existing leather slitting methods all use knives, the knives only play the role of simple cutting, and the quality of the formed products is not only difficult to guarantee, but also the production efficiency is low and the cost is expensive
