Tire retreading equipment

Abstract

The invention discloses tire retreading equipment which comprises a frame, a polishing device and a fixing device. The polishing device and the fixing device are arranged on the frame, the polishing device comprises a polishing member, a driving member for driving the polishing member to rotate and a mechanical arm for driving the polishing member to move up and down, the driving member is arranged on the mechanical arm which is connected with the polishing member through a connection structure, and the polishing member can float up and down on the connection structure. By arranging the connection structure, the polishing member can float up and down, contacts with a tread and automatically moves downwards, so that tire polishing efficiency is high; a tire body is ensured to be unchanged in thickness, and the whole tire is ensured to be unchanged in quality and high in safety.

Description

technical field [0001] The invention belongs to the technical field of tire retreading, in particular to tire retreading equipment. Background technique [0002] In the tire retreading process, grinding is a very important process. Its purpose is to grind off the surface pattern of the tire and grind 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 retreaded tires; the existing grinding machine usually uses a motor to drive the grinding head to rotate at a high speed, so that the tread can be quickly wiped off; 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 one la...

[0002] In the tire retreading process, grinding is a very important process. Its purpose is to grind off the tire surface pattern and grind 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 retreaded tires; the existing grinding machine usually uses a motor to drive the grinding head to rotate at a high speed, so that the tread can be quickly wiped off; 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 one layer. Therefore, it is necessary to continuously drive the grinding piece to move downward during grinding, and the grinding efficiency is low; It is easy to grind off a layer of carcass under the tread due to the excessive pressure of the mechanical arm, resulting in a reduction in the thickness of the carcass, resulting in safety hazards such as tire blowouts after retreading
