Device for carrying out vulcanization treatment on vamp rubber

Abstract

The invention relates to the technical field of shoemaking, and discloses a device for carrying out vulcanization treatment on vamp rubber. The device for carrying out vulcanization treatment on the vamp rubber comprises a vulcanization treatment device main body, wherein a limiting groove is formed in a vulcanization gas pipeline; a threaded hole is fixedly formed in the top of the vulcanizationgas pipeline; a bolt rod is in threaded connection with the interior of the threaded hole; a rubber elasticity tester is fixedly installed at the top of the bolt rod; a valve is slidably connected into the limiting groove; and a rotary switch is movably connected to the top of the valve. The rubber elasticity tester is installed above a vulcanization gas pipeline, a rotating wheel drives a stop lever to compress the rubber, the rotating wheel stops rotating until compression is subjected to large resistance, and at the moment, due to the fact that the rotating wheel drives the bolt rod to rotate in the threaded hole in the rotating process, the bolt rod goes deep into the limiting groove; and thus, the vulcanization gas pipeline is further blocked, and the effect of determining the amountof introduced vulcanization gas according to the physical and chemical properties of the rubber is achieved.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a device for vulcanizing vamp rubber. Background technique [0002] Vulcanized shoes use rubber, fabric or leather as the upper surface, rubber as the base material, processed by pasting, molding or injection, and then vulcanized under a certain temperature and pressure to endow the upper and sole with high strength and high elasticity. And make the two firmly combined. [0003] There are three influencing factors for the vulcanization treatment of rubber, namely the amount of vulcanization gas, the temperature during vulcanization and the time of vulcanization. The amount of vulcanization gas is related to the elasticity of rubber. When the elastic performance is good, the concentration of vulcanization gas does not need to be too high. The vulcanization time also needs to be accurately grasped. Overdue will cause the loss of some physical and chemical properties of the rubb...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for vulcanizing vulcanization of shoe upper rubber, which has the ability to control the amount of vulcanization gas entering the system through the elasticity of the rubber, and to close the vulcanization gas channel in time after the vulcanization of the rubber and the vulcanization gas in the system The advantage of not spilling into the air solves the problem of uncontrollable vulcanization gas volume and uncontrollable vulcanization time during the vulcanization of vamp rubber, which leads to the transition of vulcanization or unvulcanization of vamp rubber
