Therefore, the eccentric device is widely used in transmission systems requiring eccentric motion.

[0003] At present, the use of eccentric mechanism still has optimization space. When the traditional eccentric device is used, the initial set working posture is adopted, which makes it difficult to adjust the eccentricity of the roller in the subsequent operation, thereby affecting the stable operation of the mechanism. It is very important to control the size of the eccentricity when the eccentric device is used.

When the traditional eccentric roller adjusts the motion posture of the eccentric wheel, the eccentricity of the roller is difficult to control. With the increase of working time, the set deviation between the working surfaces of the motion will become larger, which will affect the stable state set by the motion mechanism. The inaccuracy of the eccentricity leads to low work efficiency, and the insufficient contact between the motion surfaces increases the wear of the mechanism, thereby shortening the service life of each component.

[0005] Therefore, it is necessary to provide a device for adjusting the eccentricity to solve the above technical problems. SUMMARY
