A kind of tire retreading equipment

Abstract

The invention discloses a tire retreading equipment, which comprises a frame body, a grinding device and a fixing device arranged on the frame body; the grinding device includes a grinding part, a driving part for driving the grinding part to rotate, and a A mechanical arm that drives the grinding piece to move up and down, the driving piece is arranged on the mechanical arm; the mechanical arm is connected to the grinding piece through a connecting structure, and the grinding piece can be moved up and down on the connecting structure float. The invention makes the grinding part float up and down by setting the connection structure, the grinding part contacts the tread, the grinding part moves downward automatically, and the grinding efficiency of the tire is high; it also ensures that the thickness of the carcass remains unchanged, the overall quality of the tire does not change, and the safety performance high.

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
