Claim:
1. A belt transmission device, comprising: a grinding stand; a plurality of rotation wheels mounted on the grinding stand, including a driver wheel and driven wheels; a grinding belt supported by the plurality of rotation wheels; a first sensor fixedly provided on the grinding stand and configured to detect a rotation speed of any one of the driven wheels; and a controller configured to control a rotation speed of the driver wheel and connected with a driving motor of the driver wheel, wherein the controller is further connected with the first sensor, receives rotation speed signals representing the rotation speed of the one driven wheel detected by the first sensor, calculates a difference between the rotation speed of the driver wheel and the rotation speed of the one driven wheel detected by the first sensor, compares the difference with a predetermined difference range in the controller, and initiates provision of an alarm when the difference is beyond the predetermined difference range.
