Description

Shoe press

This new type refers to a shoe printing technology that can be used to quantify production and elasticity in response to a small amount of processing capacity.

According to the current manufacturing process of the footwear industry, it can reduce the unnecessary cost waste, ensure the smooth progress of the process, and the fine product after the product is manufactured. Therefore, the combination of the midsole or the sole and the upper is adopted first. The gluing method combines the midsole or the sole of the shoe with the upper, and then sewn into one body, and in order to make the artificial coating adhesive can be positioned to be sure, the screen printing method is generally adopted, and the midsole or the sole is in the shoe. The glued area is printed with the glue marking line, so that the artificial glue can be based and followed, and the combination of the upper and the shoe midsole can be optimized to facilitate the subsequent sewing operation. This has caused a heavy burden on the production work, because the shoes of the same shoes, whether it is men's shoes or women's shoes, without the size of the shoes, the minimum standard size is at least 12 specifications, and at the same time The left and right shoe body points, so each time you open the printing plate, you need at least 24 plates to facilitate the printing operation. Because the shape of each shoe is different, and the glue range is different, it must be produced from time to time. Plate In order to facilitate the production operation, and in response to the customer's order and avoid waste, the printed plate after use is not discarded, which causes the plate to pile up, which is quite troublesome for the manufacturer.

In addition, traditional shoe materials, such as the insole or the upper printed surface, are still screen printed, but it is well known that the specifications of the shoe material are quite numerous, and for each specification or specific manufacturer. The drawings must be prepared with a corresponding set of printing plates. If it is simply combined with the marking line, it can be used for mass production operations, and it is economically beneficial because it can be used to share the printing plate production cost. When a small number of different shoe materials are printed, or when the customer requests to add their own special symbols, imprints, or special marks, the screen printing method is rather economically uneconomical, making the cost prohibitive and difficult to achieve fast delivery.
