Background

Shoes, a kind of article that prevents the foot and receive the injury when wearing on the foot, mostly straw sandals, cloth shoes in human civilization history earlier stage, it is more common today with leather shoes, sports shoes, playshoes, high-heeled shoes.

Shoes have a long history of development. Approximately 5000 years ago in the yangshao culture period, the most primitive shoe made of hide appeared. Shoes are a tool for protecting feet of people from being injured. At first, in order to overcome special conditions and prevent feet from being difficult or injured, fur shoes are invented. The development of shoes has now made this look. Shoes with various styles and functions can be seen everywhere.

There are many categories of shoe classification:

1, according to the wearing objects, there are shoes for men, women, children, etc.;

2, dividing according to seasons, and arranging shoes such as single shoes, clip shoes, cotton shoes, sandals and the like;

3, dividing the materials into leather shoes, cloth shoes, rubber shoes and plastic shoes;

4, stitching, injection molding, glue injection, mould pressing, vulcanization, cold bonding, stitch bonding, slush molding, assembly and the like according to the process;

5, dividing the head shape of the shoe according to the style, wherein the head shape of the shoe comprises a square head, a square round head, a pointed round head and a pointed head, and the heel shape comprises a flat heel, a half-high heel, a high heel and a wedge heel; the upper is provided with a high-tube part, a low-tube part, a middle part and a high part;

6, according to the usage, the shoes are divided into daily life shoes, labor protection shoes, sports shoes, travel shoes, negative heel shoes, heightening shoes and the like.

The sole is rather complex in construction and in a broad sense may include all of the materials forming the sole, such as the outsole, midsole and heel. In a narrow sense, only the outsole is referred to, and the common characteristics of the general sole materials should have the characteristics of wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to the foot shape, difficult deformation after shaping, heat preservation, easy moisture absorption and the like, and simultaneously should be matched with the midsole to have the brake function of preventing slipping and easy stopping when the foot is changed during walking. The sole materials are of various types and can be divided into natural base materials and synthetic base materials. The natural bottom materials comprise natural bottom leather, bamboo, wood and the like, and the synthetic bottom materials comprise rubber, plastics, rubber and plastic combined materials, regenerated leather, elastic hardboard and the like.

At present, most soles of shoes are designed in a multi-layer mode, namely the soles are bonded by glue and then pressed. Specifically, an external force is needed in the bonding process to attach the parts to be bonded subjected to the sizing treatment to each other and apply a certain pressure. The existing sole pressing and drying device is complex in operation and low in automation degree, and shoes need to wait for glue to be dried, so that the working efficiency is low, and therefore a sole pressing and drying device based on incomplete gear rotation needs to be designed, and the pressing and drying automation is realized.
