Upper conveying mechanism

Abstract

The invention discloses an upper conveying mechanism, which comprises a pair of transmission chains, a seat body and a support frame, wherein the seat body is fixedly arranged on the transmission chains; the support frame comprises a connecting block and two pairs of cylindrical clamping rods; the connecting block is fixedly arranged on the seat body; the two pairs of cylindrical clamping rings are arranged on the connecting block; a bump is arranged on the end part of at least one clamping rod of each pair of clamping rods; external threads are formed at the positions, close to the end parts with the bumps, of the clamping rods; grooves are formed in the lateral surfaces of the connecting block; one end of each groove penetrates through the adjacent lateral surface; the cross section of each groove is shaped like a Chinese character Tu; the bumps are clamped into the grooves; nuts are screwed to the external threads of the clamping rods; the walls of the grooves are clamped between the bumps and the nuts. According to the technical scheme, the distance between the two clamping rods of each pair can be adjusted, and when the distance between the two clamping rods is suitable for clamping an upper to be dried, an operator can tighten the nuts to fix the distance between the two clamping rods; therefore, uppers with different sizes can be clamped by each pair of clamping rods, and the upper conveying mechanism is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of shoemaking machinery, in particular to a shoe upper conveying mechanism. Background technique [0002] It is generally known that in the shoemaking process, the bonding of the sole and the vamp requires glue. In actual production, before the sole and upper are bonded, glue is first applied to the part to be bonded, and then the glue is moderately dried to enhance the bonding effect. [0003] The invention of Patent No. 97222379.7 discloses a shoe-making laminating machine, which is used by producers to process drying glue. The shoe-making laminating machine is divided into upper and lower layers, and the bottom surface of the lower drying chamber There is a chain conveyor, which is specially used to transport the shoe upper, and the shoe upper can be reversed and reversed between two clamping bars. [0004] However, the distance between the above-mentioned two clamping bars is a fixed value, but the siz...

Problems solved by technology

[0004] However, the distance between the above-mentioned two clamping bars is a fixed value, but the size of the upper is different. For example, the size difference between children's shoes and adult shoes is very large. In this way, two clamping bars can place larger size shoes. However, the smaller size uppers cannot be placed on the upper, and on the contrary, the pair of clamp bars that can be placed on the smaller size uppers cannot be placed on the larger size uppers
