Description

Technical Field

[0001] The utility model relates to the technical field of shoe upper processing, and specifically relates to a hot pressing and forming machine for drip glue shoe upper processing. Background Art

[0002] In the footwear manufacturing industry, the aesthetics, durability, and comfort of shoe uppers are important indicators for measuring product quality. With the diversification of consumer demands, shoe upper processing technologies have been continuously innovated. Among them, drip glue shoe uppers (i.e., KPU shoe uppers) have been widely used in the fields of sports shoes, casual shoes, etc. KPU shoe uppers also have good elasticity and tensile properties, can keep the shape of the shoe upper stable during wearing, are not easy to deform, and can effectively wrap the feet, providing good support and protection for the feet.

[0003] The drip glue shoe upper uses a process of heating and softening the material with high temperature and pressure and then shaping it into a specific shape through a mold. In the production process of KPU shoe uppers, it is usually processed by hot pressing and forming technology. First, the KPU material needs to be heated and softened, and then shaped into the required shoe upper shape in the mold. Then, the heating plate of the hot pressing and forming machine heats the shoe upper material to make it in a plastic state, and then pressure is applied to make the material form in the mold, and drip glue reinforcement is carried out during this process to improve the structural strength and aesthetics of the shoe upper.

[0004] The structure of the current forming machine for drip glue shoe uppers is generally similar to that of a drip molding shoe material machine disclosed in the patent application number "CN202120917147.2", including: a machine frame, a circular workbench is installed on the top of the machine frame, and a motor is arranged below the circular workbench, and the motor is fixedly connected to the machine frame; a locking template, which is installed inside the machine frame, and the locking template is connected to the mounting plate through machine columns and machine column nuts. Through the mutual cooperation of the machine frame, the motor and the circular workbench, the circular workbench can rotate. The circular workbench is equally divided into six workstations, so that the processing procedures are integrated on the surface of the circular workbench. Driven by the motor, the circular workbench can be driven into each working area for processing to realize the automation of processing. And the circular workbench can place 6 molds at the same time, and each mold can work simultaneously at different functional stations. However, this utility model can only transfer the shoe upper mold to the oven for drying, and the subsequent work of fusing and integrating the formed drip glue and the shoe upper material sheet still needs to be operated manually. The operation steps are complex, and the working environment is in a high-temperature state, reducing the working efficiency.

[0005] Therefore, the utility model provides a hot pressing and forming machine for drip glue shoe upper processing to solve the above problems. Summary of the Utility Model
