Description

Technical Field

[0001] The utility model relates to the technical field of rubber tire processing equipment, in particular to a rubber tire grinding device. Background Art

[0002] Rubber tires are tires made of rubber. Because rubber tires are relatively soft and have strong shock-absorbing functions, they can prevent internal car parts from being damaged. Rubber tires are also very durable and low in cost, so they are very convenient to use.

[0003] However, after the existing rubber tires are produced, burrs will appear on the outer surface of their side walls, which need to be removed. For this reason, a Chinese utility model patent with authorization announcement number CN213034244U discloses a rubber tire grinding device, which drives the rubber tire on the first rotating shaft to rotate by a motor, so that grinders located on both sides of the rubber tire can grind the burrs on the side walls of the rubber tire. Although the above patent can grind the rubber tire, in the process of adjusting the total length of several support rods and connecting rods to tighten the rubber tire, each support rod and adjusting rod needs to be adjusted, which is very inconvenient to operate. In addition, in the process of adjusting the total length of each support rod and connecting rod, there will be errors in the length, which will cause the total length of several support rods and connecting rods to be inconsistent, which will deform the rubber tire support and affect the grinding effect of the tire.
