Description

technical field [0001] The invention relates to the field of tire equipment, in particular to a non-powered adjustable grinding wheel device for grinding tire cutting belts. Background technique [0002] The rubber slicer uses a circular belt-shaped knife belt to slice the leather. After long-term use, the blade of the knife belt will be worn or attached to the leather, resulting in a decrease in cutting efficiency and cutting accuracy. On the traditional rubber slicer, a sharpening wheel is set at a certain position of the knife belt's movement track, and the grinding wheel is driven by a motor to grind the cutting edge of the knife belt during the working process of the knife belt. The disadvantages of this grinding wheel are: 1. It needs to be driven by a motor, and the grinding force is large, and the knife belt is forcibly ground, which is easy to damage the knife belt; 2. When grinding the upper and lower surfaces of the knife belt simultaneously, two grinding wheels a...
