2. when tires of different types are detected, the distance between the two conveying belts needs to be manually adjusted to be positioned at a proper position, so that the labor intensity of workers is increased, and the working efficiency is reduced;
3. the upper half rim and the lower half rim are fixed on the driven shaft and the power shaft manually, so that the labor intensity of workers is further increased, and the working efficiency is reduced;
4. the transverse clamping mechanism has poor adaptability to different types of tires, can not ensure the same clamping effect on different types of tires, and influences the assembly of the tires and the rim;
