Description

A tire retreading equipment based on resource reuse

technical field

The invention belongs to the technical field of tire retreading, and in particular relates to a tire retreading device based on resource reuse.

Background technique

Grinding is a very important process in the tire retreading process. The purpose is to polish the tire surface pattern and polish it into a tread with uniform roughness, which is convenient for replacing the tire with a new tread. The quality of grinding will directly affect the The quality of the retreaded tires; the existing grinder usually uses a motor to drive the grinding head to rotate at a high speed, so that the tread can be quickly wiped off; during the grinding process of the grinder, because the mechanical arm drives the grinder to move downward, the grinding The machine and the tread are in hard contact. During the grinding process, the mechanical arm drives the grinding piece to move downward, and the mechanical arm exerts downward pressure on the grinding piece. After grinding a layer during the grinding process, the mechanical arm needs to drive the grinding piece. Move down once, and then re-grind off a layer. Therefore, when grinding, it is necessary to continuously drive the grinding piece to move downward, and its grinding efficiency is low; and it is not easy for the mechanical arm to control the grinding piece to completely grind off the tread. It is easy to polish off a layer of the carcass under the tread because the pressure of the mechanical arm is too large, resulting in a reduction in the thickness of the carcass, resulting in safety hazards such as puncture of the retreaded tire.
