Problems solved by technology

[0005] However, most of the shoes made by the bonding process have limited strength. During the long-term wearing process, especially after being disturbed by non-vertical forces, the bonding strength will decrease significantly, and the phenomenon of glue opening or cracking will easily occur, which will affect the The normal use of shoes, and cracks in the early stage, including the bonding process and the later wearing process, are prone to cracks. Once the cracks cannot be detected in time, the cracks will gradually become larger until the shoes are completely scrapped

Embodiment 1

[0047] see figure 1 , a cracking self-reminder type shoe-making process, comprising the following steps:

[0048] S1. Use a grinding wheel to sand the surface of the sole to be bonded to make the surface rough, and then remove the sanding dust;

[0049] S2. Brush the adhesive onto the joint between the sole and the upper, and then take multiple prompt balls and bury them evenly in the adhesive on the sole in an oxygen-free environment, and wait for the adhesive to dry naturally;

[0050] S3. Apply pressure to the sole through the upper, and heat until the adhesive becomes sticky during the pressure application process, and continue to apply pressure until the upper and the sole are bonded;

[0051] S4. After the pressing is completed, observe whether the prompt ball has a crack prompt. If there is a crack prompt, separate the upper and sole to replace the prompt ball and then bond the second time. If there is no crack prompt, the bonding is qualified;

[0052] S5. After pass...

Abstract

The invention discloses a cracking self-prompting type shoemaking process, and belongs to the technical field of shoemaking. A plurality of prompting balls can be embedded in an adhesive in advance in a bonding process. The prompting balls can be directly embedded in a joint between a sole and an upper to improve the non-vertical deformation resistance of the joint. Meanwhile, in the bonding process, as a standard for firm bonding, defective products can be directly found in the bonding process, and after the shoes are formed, once glue failure or cracking occurs in the daily wearing process, external air can enter and make contact with the prompting balls. After the prompting balls make contact with oxygen in the air and trigger a self-heating reaction, the prompting balls release liquid with a prompting effect. On one hand, the liquid can be temporarily used as an adhesive substitute to avoid further cracking; and on the other hand, a user is prompted to take measures in time, so that the service life of the shoes is prolonged.

Description

technical field [0001] The invention relates to the technical field of shoemaking, and more specifically relates to a cracking self-reminder type shoemaking process. Background technique [0002] Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. In order to overcome special conditions and prevent feet from being uncomfortable or injured, people first invented fur shoes. Shoes have developed to the present, and they have formed what they are now. Shoes of various styles and functions can be seen everywhere. [0003] Shoe-making process: China's shoe-making process has been using hand-stitched molding process for a long time. Since the 20th century, advanced technology and special equipment have been introduced from abroad, and the shoemaking process has developed rapidly, which can be roughly divided into sew...
