Tire grinding machine capable of improving grinding efficiency

Abstract

The invention belongs to the technical field of tire machining equipment, and discloses a tire grinding machine capable of improving grinding efficiency, the tire grinding machine comprises a base, the middle of the upper end of the base is fixedly connected with a workbench, and the middle of the workbench is movably sleeved with a supporting ring. Through the arrangement of the cylindrical roller, the double-shaft motor, the sand roller and the supporting ring, in the grinding process, the supporting ring provided with an inner gear ring is decelerated twice through a first gear and a second gear, it is guaranteed that the supporting ring drives a tire to move slowly, and on the other hand, it can be guaranteed that a conveying belt drives the sand roller to rotate rapidly; a large speed difference is provided, the grinding efficiency is improved, meanwhile, the relative position of the cylindrical roller and the emery roll does not change, the cylindrical roller can continuously support the interior of the tire tread in a grinding area, the grinding effect of the emery roll on the tire tread can be further ensured, meanwhile, the cylindrical roller can roll automatically, damage to the tire tread of the tire is avoided, and the service life of the tire tread is prolonged. Therefore, the grinding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tire processing equipment, in particular to a tire sander for improving grinding efficiency. Background technique [0002] Generally, for the grinding of tire treads, the following two situations are mainly involved. One is to grind new tires to remove some edges and corners and excess parts generated during tire production and processing, and to grind and cut new stubble parts to improve tires and improve their smoothness and cleanliness; One is the retreading of old tires. By polishing the tire surface cleanly, the oil stains, impurities, and damaged parts that have been contaminated by the tire tread after long-term use are removed. [0003] The existing grinding method is to fix or locate the tire near the grinding wheel, preferably after the tire is fixed, the tire can be rotated along its axis to grind the circumferential surface of the tire, such as the tension manipulator mentioned in the applica...

AI Technical Summary

Problems solved by technology

However, there are still deficiencies in its specific use process: first, the tire does not have an internal support device, which is easy to cause relative sliding when the tire is polished, and the tire tread is easily deformed under pressure; secondly, when the tire surface is polished, the grinding tool is close to the tire It is difficult to effectively control the adhesion force on the surface. If the adhesion is too tight, it will easily cause the tire to deform, and the tire will be flattened, and the deformed tire will be easily polished excessively and unevenly; if the adhesion is too loose, the grinding effect of the tire is not enough, so a Grinding equipment with good fixing effect and stable tension, which can ensure the degree of grinding and improve the grinding efficiency
