Description

Technical Field

[0001] This utility model relates to the field of magnetic screening machine processing, and in particular to a magnetic screening machine anti-deviation belt roller mechanism. Background Technology

[0002] Magnetic screening machines are used to remove iron powder and other pollutants from recycled powders and granules. They are also important processing equipment in plastic particle processing, used to screen out metal powder from plastic particles. They are mainly composed of a cylinder, drive rollers, conveyor belts, brush rollers, magnetic system, trough, and transmission parts. Among them, the drive rollers and conveyor belts are the main components for conveying materials. There are two sets of drive rollers, arranged one in front and one behind. The conveyor belt is sleeved on the outside of the two sets of drive rollers. One set of drive rollers is connected to the transmission part, which drives the drive rollers connected to it to rotate. This, together with the other set of drive rollers, causes the conveyor belt to rotate, conveying the screened material.

[0003] However, existing magnetic screening machines ensure that the transmission belt is in the middle position of the transmission rollers during operation by adjusting the parallelism of the two transmission rollers. However, there are errors in the coaxiality of the transmission rollers during the manufacturing process, and there are bound to be errors in the relative parallelism of the two sets of transmission rollers on the magnetic screening machine. In addition, there are length errors in the transmission belt during the manufacturing process. Therefore, simply adjusting the parallelism of the transmission roller shafts cannot ensure that the belt will not deviate. Summary of the Invention
