Automatic manufacturing process of rubber double-density shoes

Abstract

This invention provides an automated manufacturing process for dual-density rubber footwear, relating to the field of shoemaking technology. The automated manufacturing process includes the following steps: wetting the material and then tightly wrapping and bonding it to a mold; fixing it with a fixing device; drying and shaping with a drying device; keeping the shaped material fixed on the mold; and cutting it at different locations using a cutting device to obtain the toe, lining, tongue, edge, heel counter, and midsole. The outer surface of the shoe is then wrinkle-removed and sanded, and rubber strips are sewn into pre-defined locations. The shoe obtained in step 5 is removed from the mold, holes are drilled using a punching device, and shoelaces are inserted into the shoe for final packaging. This process solves the problems of traditional shoemaking processes, which suffer from insufficient standardization, resulting in poor product quality, low efficiency, and high labor requirements, failing to meet the demands of modern mass production.

Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to an automated manufacturing process for dual-density rubber shoes and boots. Background Technology

[0002] Shoes have a long history of development. The earliest shoes made of animal hides appeared around 5,000 years ago during the Yangshao Culture period. Shoes are a tool for people to protect their feet from injury. In order to overcome special circumstances and prevent their feet from being uncomfortable or injured, people invented fur shoes. Shoes have developed into what they are today, with various styles and functions of shoes everywhere.

[0003] Boots are a type of footwear worn on the feet that at least cover the soles and ankles, extending to the calves and even the knees. Boots can come in various heights, colors, materials, and styles, and most have a prominent heel.

[0004] With the rapid development of the footwear industry, automated production has been adopted by many footwear companies, especially in countries with high levels of automation in Europe and America. Domestically, the use of automated manufacturing is also in a period of rapid development, but most of them use adhesive bonding or PU injection molding processes. Rubber dual-density injection molded footwear products are still almost entirely produced according to traditional footwear manufacturing processes. Due to insufficient standardization, traditional footwear manufacturing processes result in poor product quality, low efficiency, and a large labor requirement, which cannot meet the demands of mass production in modern society. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated manufacturing process for dual-density rubber footwear, which solves the problems of poor product quality, low efficiency, and high labor requirements in traditional shoe manufacturing processes due to insufficient standardization, which cannot meet the demands of mass production in modern society.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated manufacturing process for dual-density rubber footwear, comprising the following steps:

[0019] Preferably, in step S1, the setting time is typically 18-24 hours.

[0020] Working principle: After the material is soaked, it is tightly wrapped and adhered to the mold. It is then fixed by a fixing device and dried and shaped by a drying device. The shaped material is kept fixed on the mold. The cutting device cuts different positions to obtain the toe, lining, tongue, edge, heel counter, and waistband. The sole is fixed to the bottom of the mold by a robotic arm. Then, an automated sewing machine sews the sole to the toe, lining, tongue, edge, heel counter, and waistband. Finally, the sewn shoe is removed from the mold. The lining fabric is wrapped around the mold, and the shoe is put on the mold and sewn by an automated sewing machine. The cutting device cuts off the excess fabric. The shoe obtained in step 4 is removed from the mold. The outer surface of the shoe is wrinkle-removed and sanded. Rubber strips are sewn into the reserved positions. The shoe obtained in step 5 is removed from the mold. Holes are drilled by a punching device. The shoelaces are then put into the shoe for finished product packaging.
