Manufacturing method and device for footwear

Abstract

A shoe manufacturing method and its manufacturing device. The shoe manufacturing device includes a last set for pre-positioning a plurality of shoe parts, a device that covers the shoe and defines an airtight space with the last set A diaphragm group, a pressure unit for removing air in the airtight space, and a heating unit for generating heat energy and transferring it to the shoe. The diaphragm group shrinks and deforms under the action of negative pressure, and forces the shoe parts to be bonded to each other during the heating process. In this way, the negative pressure environment constructed by the diaphragm group and the last group is used to achieve the purpose of combining the shoe, which not only simplifies the production process and simplifies the components, but also further improves the production efficiency.

Description

technical field [0001] The invention relates to a shoe, in particular to a shoe manufacturing method and a manufacturing device thereof. Background technique [0002] The finished shoe is mainly composed of shoe uppers, soles and other shoe parts, and further, for reinforcement and decoration, it also includes reinforcement pieces, shoe eyelets, tongues, decorative pieces and other shoe parts. The above-mentioned shoe parts are usually bonded together by hot pressing glue. However, if the aforementioned heat-pressing and gluing process is manual, not only is the quality difficult to stabilize, but the process is time-consuming and increases the cost. [0003] refer to figure 1 , to illustrate an existing system 1 for applying heat and pressure to three-dimensional objects disclosed in Chinese Patent Publication No. 107518525, mainly through an intermediate member 11 and a base member 12 that are combined upper and lower A closed space 13 for accommodating a footwear unit ...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the air in the aforementioned confined space 13 is removed by holes (not shown) on the base member 12, the arrangement position of the footwear unit 2 on the base member 12 cannot cover the aforementioned limited by holes

[0006] 2. Based on the aforementioned processing methods, each system can only proceed to the next manufacturing process after each footwear unit 2 is glued together and removed from the base member 12 during the manufacturing process. Therefore, the manufacturing efficiency is still high. limited

[0007] 3. In addition, in order to construct the aforementioned confined space 13, the base member 12 and the intermediate member 11 must be added, which not only complicates the structure, but also keeps the cost high
