[0002] The driving roller is the transmission shaft of the lifting belt, which is driven by a DC speed-adjustable motor M9. When working, the motor rotates the driving roller, and the driving roller drives the lifting belt to move upward. The lifting belt is a belt with a width of 770mm, a thickness of 1.5mm, and a circumference of 4366mm. 350 stainless steel tooth plates are evenly installed on the belt. The frame is the support of the lifting belt. By adjusting the adjustment screw, the lifting belt can be effectively tensioned through the action of the tensioning device.

[0003] According to the maintenance records, there were 32 oil smoke incidents due to partial failure of the lifting belt throughout the year, with a total maintenance time of 1,810 minutes. Among them, the coupling (copper gear) was damaged 20 times, and the maintenance time was 700 minutes. Frequent failures in this part and long maintenance time seriously affected the full performance of the equipment. During the production process, the staff found that the connecting shaft could not fully engage with the coupling, causing the coupling to often be half worn (shaved), the lifting belt stopped feeding, the machine stopped, and the display "metering trough empty" was displayed. Summary of the invention

[0004] To solve the above problems, the present application provides a transmission device for the lifting belt of a feeding strip-forming machine, which aims to cause the connecting shaft to move right through the spacer sleeve between the disc accelerator and the bearing sleeve, thereby making the connecting shaft fully engage with the coupling and reducing the wear of the coupling.
