Operation process of folding edges on uppers of leather shoes through machine

Abstract

The invention discloses an operation process of folding edges on uppers of leather shoes through a machine. The operation process includes the steps that a process book is read carefully to learn the structure of the sample uppers, and whether the style number, the color, the size and the serial number of the uppers coincide with the content of a process flow card or not is checked; the temperature of the folding machine is adjusted; the temperature of a presser foot is 150 DEG C+ / -5 DEG C, the temperature of a hot melt glue disc is 160 DEG C+ / -5 DEG C, and only when the temperature meets the requirement, can operation be carried out; the height of the presser foot of the folding machine and the width of needed edge folding are adjusted; according to presser foot profile modeling, close to the folding machine, of the upper face marked lines, operation is performed along the marked line positions; a rolled edge presser foot is replaced in the rolled edge wrapping process, and the tightness degree of the presser foot is adjusted according to the requirement for the width of rolled edges; the sizes of the rolled edges are required to be uniform. According to the process, the edge folding efficiency is improved, the quality can be controlled strictly in batch production of an enterprise, and edge folding of the uppers of the leather shoes is systematized into working procedures.

Description

technical field [0001] The invention relates to a process, in particular to a process based on machine hemming operation of leather uppers. Background technique [0002] Using natural leather as the main raw material to cooperate with other synthetic materials to make shoes is called leather shoes. Thousands of years ago, human ancestors had the habit of wearing shoes, from wrapping their feet with animal skins and making shoes with leather to modern leather shoes. The history of wearing leather shoes is quite long. In China, the production of modern leather shoes has only a history of more than 120 years, but because the shape, style, structure and wearing function of leather shoes are better than other footwear, the production of leather shoes has developed rapidly. Nowadays, leather shoes have become a kind of footwear that people like most, and become one of bulk commodities that beautify people's lives. Leather shoes developed with the appearance of leather.

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned prior hemming process of uppers of leather shoes, in which operators perform hemming according to their own experience, resulting in uneven quality of upper hemming, which is difficult for enterprises to produce in batches. Quality control, and the low efficiency of hemming, resulting in high production costs. A machine hemming operation process based on the upper surface of leather shoes is designed. This process improves the efficiency of hemming, improves the quality of hemming, and reduces The production cost is reduced, and the batch production of the enterprise can strictly control the quality, and the system process is carried out on the hemming of the upper of the leather shoe, which solves the problem that in the existing process of hemming the upper of the leather shoe, all the operators are based on their own requirements. Folding by experience leads to uneven quality of the upper hemming, which cannot control the quality for the mass production of the enterprise, and the efficiency of hemming is low, resulting in high production costs.
