Sole smoothing device used before adhesion of soles and vamps

Abstract

The invention provides a sole smoothing device used before adhesion of soles and vamps. Shoe racks are installed on the surfaces of the left side and the right side of a supporting plate in a slidingmanner correspondingly. A compression spring is fixedly connected to the bottom of each shoe rack. A variable resistor is arranged at the connection position of each shoe rack and a supporting plate.A metal sheet is arranged on the surface of each variable resistor and in the corresponding shoe rack. A bottom rod is movably installed on the lower surface of each scraping base. While the shoe soles are fixed through the shoe racks and the supporting plate, the positions of the metal sheets and the variable resistors are regulated through movement, in the supporting plate, of the shoe racks, the resistance value, connected into a circuit, of the variable resistors is further regulated, the current in coils connected with the variable resistors in series is regulated, it is ensured that magnets are pushed by magnetic fields generated by the coils, connecting rods are pushed to move outwards in rotating discs, and the diameter of rotation, driven by the rotating discs, of the connecting rods is changed; and the smaller the shoe sole size is, the smaller the vertical amplitude of the scraping bases is, the smoothing range is automatically regulated according to the shoe sole size, andother surfaces of the shoe soles are prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of shoe-making equipment, and in particular relates to a shoe sole grinding device before shoe soles and uppers are adhered. Background technique [0002] Shoes are a tool that is convenient for people to walk and protect feet from injury. Its types include leather shoes, sports shoes, cloth shoes, slippers, rubber shoes, etc., which are mainly divided into two parts: the sole and the upper. It is stitched or glued together with the upper, and before the sole and upper are glued together, the sole and the upper need to be made first, and then the inside of the sole is smoothed before the subsequent process. [0003] In the process of grinding, the grinding effect is not good, and it is easy to produce unevenness, which affects the tightness between the shoes, resulting in air bubbles left inside the sole after molding. In addition, the grinding and smoothing cannot be automatically adjusted according to the ...

Problems solved by technology

[0003] In the process of grinding, the grinding effect is not good, and it is easy to produce unevenness, which affects the tightness between the shoes, resulting in air bubbles left inside the sole after molding. In addition, the grinding and smoothing cannot be automatically adjusted according to the size of the sole. range, the debris after grinding accumulates inside, making it extremely easy to adhere to the surface of the sole, affecting subsequent adhesion
