Vehicle tire polishing device

Abstract

The invention belongs to the technical field of grinding equipment, and discloses a vehicle tire grinding device which comprises a base, the middle of the upper portion of the base is movably sleeved with a rotating shaft, the upper portion of the base extends rightwards to penetrate through the rotating shaft to be fixedly provided with a first fixing shaft, and second fixing shafts are fixedly installed on the right end face of the rotating shaft in the circumferential direction in an array mode. A belt motor is fixedly installed on the lower portion of the base, the belt motor is connected with the rotating shaft through a belt, and the right end of the first fixing shaft is movably sleeved with a supporting rim. According to the device, the first fixing shaft and the base are fixedly installed, after the supporting rim rotates, the first fixing shaft rotates relative to the supporting rim, so that transmission teeth are driven to rotate, a rotating sleeve is driven to rotate, a supporting plate slides on the inner surface of a tire, and the supporting plate is always kept at the original position for supporting, that is, in the rotating and grinding process of the tire through a first grinding block and a second grinding block; and the ground part of the tire is always supported by the supporting plate, so that the ground flatness of the surface of the tire is ensured.

Description

technical field [0001] The invention belongs to the technical field of grinding equipment, in particular to a vehicle tire grinding device. Background technique [0002] There are two situations involved in the tire grinding process, one is the retreading of the tire, by grinding the tire surface clean, removing the oil stains and damaged parts, etc., the other is grinding some corners and excess parts of the new tire, and after grinding and cutting The new part of the new crop, tire retreading is a positive way to recycle waste tires, and it is an extension and processing and reuse of the tire industry. It is of positive significance for promoting resource conservation and comprehensive utilization, stimulating economic growth mode transformation and sustainable development. [0003] Tire retreading refers to a process of partially repairing old tires, polishing them, reattaching tread rubber, and then vulcanizing to restore their use value.

Problems solved by technology

[0003] Tire retreading refers to a process of partially repairing old tires, polishing them, reattaching tread rubber, and then vulcanizing to restore their use value. After a long-term use of automobile tires, the tread pattern is worn out. Flat, the reduction of the adhesion between the tire and the road surface will affect the traction and passing performance of the car, and increase fuel consumption. When grinding to a certain limit, tire retreading should be carried out in time. The existing application number is 201410161153.4, which is a patent named retreaded tire grinding and clamping device. When clamping the tire before grinding, it only uses the claws that expand outwards To clamp the tire, the inner surface of the tire contacted by the outwardly expanding claws will support the tire, deform the tire, and cause the tire to be non-circular. When the claws drive the tire to rotate, the claws hold the position of the tire Unchanged, which in turn leads to uneven thickness of tread grinding during the grinding process
