Analysis Of Tension Strength Of Slippers Shoe Buckle

　　 Garden shoes One of the slippers was originally named for gardeners, but later it was both practical and useful. fashion And light. Comfortable Its characteristics have been rapidly promoted in the European and American markets, and more and more people like garden shoes. The export volume of garden shoes has been increasing year by year, and the export volume of children's shoes has been increasing year by year, making great contributions to the export earning of foreign exchange.

There are many kinds of garden shoes, most of which are used in the design of shoes. Shoe buckle 。 According to the rules for inspection of plastic shoes in footwear inspection regulations (SN1309.3-2003), the small accessory tension project of children's shoes must meet the requirements of 70N, otherwise there will be a safety risk of falling off and easy to be swallowed by children. The shoe buckle of children's shoes is also referenced to this standard. In recent years, while the export volume of garden shoes is increasing, the risk of shoe buckle pulling is increasing. The shoes exported to the adjacent areas have been returned because of the tensile strength of the shoe buckle. In the author's work, many unqualified batches have been detected many times. Combined with years of work experience, the author makes the following analysis of the reasons for the unqualified tensile strength of garden shoe buckle.

Material reason. The shoe buttons needed for garden shoes are mainly nylon or carbon resin. Nylon has the advantages of good toughness and high hardness, but the disadvantage is that it is difficult to process. After the shoe button is formed, it needs to be boiled, and the boiling time is not easy to master. Therefore, most manufacturers usually take polycarbonate resin. Although the polycarbonate resin has the advantages of low cost and easy forming, it has poor hardness and is easy to break. The shoe buckle produced by it is easy to cause breakage. According to statistics, 6 batches of unqualified batches of garden shoes have been detected in this area, of which 5 batches of materials are polycarbonate resins, accounting for about 83.33% of the total.

Design reason. Because of the beauty and good use of shoe buttons often play a role in finishing, so in recent years, the design of shoe buckle also appeared "heavy pattern, light function" characteristics, a wide variety of shoe buckle emerge in an endless stream, but the problem of fastness is rarely included in the designer's vision. In fact, no matter how the design of shoe buckle is refurbished, it is more than 3 kinds of buckle type, button type and slide button type, and the most easily quality problem is the buckle type shoe buckle. This requires that when designing, we should give full consideration to the tightness of the button and the female button. If there is a bad design, there will be a larger gap between the two buckles, which will cause the shoe buttons to fall off and eventually lead to the failure of the small accessory tension project.

Reasons for operation. This is mainly in the buckle type shoe buckle. The buckle shoe buckle is made up of "button" and "female button". In the process of processing, the button should be inserted into the upper, then connected to the EVA shoelace, and finally pressed the female button and the button. The key process is the last step. If the operation is not in place, it may cause the button and the female button to not be pressed tightly, so it is easy to fall off. For some nylon shoe buckles, because of their strong hardness, it is more difficult for them to make the buttons and the female buckle together. Therefore, some "experienced" enterprises or employees have adopted a flexible method, first blowing the shoe buttons with electric hair dryer, then compressing them. Practice has proved that this method is not enough, because hot air easily causes the deformation of shoe buckles, and the shoe buckles are easier to fall off.

How to solve the problem of tension strength of children's shoes is a serious topic. Improper handling may bring immeasurable losses to export enterprises and even affect the export safety of the whole industry. We should fully evaluate the samples provided by customers, do not blindly rely on sample production and processing, and do not blindly rely on production and processing, and do not cut corners and shoddy products, and handle the relationship between "design" and "quality", avoid product design defects, standardize production awareness, strengthen production management, strictly operate according to the work instructions, and pay close attention to the new problems and new situations that arise in the production, strengthen the professional skills training for employees, ensure the quality and safety of export products, and strictly control the awareness: we should pay attention to the purchase of raw and auxiliary materials, ensure that the materials used are in line with the requirements of importing countries, and strengthen the inspection of semi finished products and finished products, so as to ensure that every pair of shoes manufactured does not have hidden dangers. In order to ensure the smooth clearance of export products and earnestly maintain the market position of garden shoes in the international market, I remind enterprises that in the future production, we should strengthen the "three consciousnesses": the sense of good faith management: after receiving orders,
