Embodiment 1

[0015] After the tire carcass is inspected and polished, it is put into the vulcanization equipment. After inflation and mold closing, the rubber material is injected into the gap between the inner wall of the vulcanization mold and the tread through the injection device. The rubber material is filled in the mold cavity, and the control device senses After reaching the filling level, proceed to vulcanization.

Embodiment 2

[0017] After the tire carcass is inspected and polished, it is put into the vulcanization equipment;

[0018] Mix the rubber compound with the reinforcing short fiber in the injection device;

[0019] After the vulcanization equipment is inflated and the mold is closed, the mixture of rubber and short fibers is injected into the gap between the inner wall of the vulcanization mold and the tread through the injection device, and the mixture is filled in the mold cavity. After the control device senses the filling amount, vulcanization is carried out.

[0020] The tire vulcanization equipment in Embodiment 1 and Embodiment 2 includes a heating device, a vulcanization chamber 5, a control device, an upper mold 2 and a lower mold 4, the lower mold 4 is arranged in the vulcanization chamber 5, and the upper mold 2 passes through the supporting device 1 is connected to the vulcanization equipment 6 and cooperates with the lower mold 4, and the upper mold 2 and the lower mold 4 are b...

Abstract

The invention relates to a tire retreading method and vulcanizing equipment for implementing the retreading method. The tire retreading method comprises a tire body checking step, a tire body grinding step and a vulcanizing step, and comprises the following specific steps: grinding the checked tire body; after grinding, arranging the ground tire body into the vulcanizing equipment; inflating and performing die assembly; injecting a sizing material into a gap between the inner wall of a vulcanizing mold and a tire tread through an injection device; filling a mold cavity with the sizing material for vulcanizing. Compared with the prior art, the technical scheme has the advantages that rubber cement does not need to be painted, environmental protection is facilitated, rubber cement, petroleum and labor force are saved, the production efficiency is improved, the labor condition is improved, the health of workers is protected, the influence on a tire caused by few or excessive sizing material is eliminated, and the product quality is improved.

Description

technical field [0001] The invention relates to a tire retreading method and vulcanization equipment for realizing the retreading method. Background technique [0002] The traditional tire retreading process includes: carcass inspection, carcass grinding, carcass repair, carcass brushing with glue, carcass with tread rubber, vulcanization, and edge trimming inspection. [0003] In the original traditional process, after the carcass is pasted with tread rubber, there may be insufficient or excess glue. Although it can be repaired manually after grinding and pasting, some inevitable problems will still occur, which may lead to Lack of rubber in the vulcanization process will cause tire defects or excessive rubber will block the air holes, which will cause air bubbles in the tire, and seriously cause the tire to become a waste product. Contents of the invention [0004] In order to solve the problem in the prior art that lack of glue causes tire defects and excess glue cause...
