Technical Field

The invention relates to a shoe production process, in particular to a cold-bond thread shoe forming process.

Background

The leather shoes are made of leather, cloth and rubber, have a long development history, are the most primitive shoes sewn by animal skins in the Yangshao culture period of more than 5000 years ago, are a tool for protecting feet from being injured by people, and are invented for overcoming special conditions and preventing the feet from being difficult or injured by people at first.

The variety of shoes on the market is various, but most of the existing shoes are improved on the structure and the performance of a sole or an upper surface, the quality stability and the foot fitting comfort of the combination of the upper and the lower are rarely carried out around the upper and the lower, the quality stability and the foot fitting comfort of a product are closely related to the whole process of shoe making, each step has certain influence on the quality of the shoes, the glue consumption is large in the existing upper and the lower joint, and the upper and the lower sewing are easy to break.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a cold-bond stitch line shoe forming process which is mature, firstly, the lasting upper body is subjected to steaming, drying, brushing and drying again to ensure that the lasting upper body is stably formed, secondly, the sole is subjected to the pretreatment of brushing, drying, brushing and drying again to ensure that the sole is convenient to be bonded subsequently, then the lasting upper body and the sole are sequentially subjected to two bonding treatments of fixed-point manual pressure bonding and mechanical bonding to improve the bonding effect, then the upper and sole connected body is placed in a freezing box to be frozen and stabilized, the bonding stability of the upper and sole connected body is improved, finally, last removing, stitching and finishing are carried out, and a plurality of needles extend at the superposition position of stitch line running pins to improve the firmness of stitches, the whole processing process is compared with the prior art, the upper and sole are sewn firmly and connected tightly, the condition of fracture can not appear easily, and only carry out the brush and glue the processing under the prerequisite that does not influence adhesive strength, reduce the glue quantity, promote production technology's feature of environmental protection, adopt the high-elastic EVA sole of light, wear merrily and lightheartedly, comfortable.
