The output end of the second servo motor 19 is connected to the first rotating shaft 4. The movement of the device is realized by the operation of the first servo motor 17 and the second servo motor 19. The transmission efficiency is high through the cooperation of the synchronous wheel 18 and the synchronous belt, and chainless transmission is realized. The first servo motor 17 works to realize the rotation of the transmission roller 2, and the second servo motor 19 works to realize the rotation of the first rotating shaft 4.

[0025] Working principle: The first servo motor 17 drives one of the synchronous wheels 18 to rotate, and the synchronous belt drive realizes the rotation of the two synchronous wheels 18, which in turn drives one of the transmission rollers 2 to rotate, and drives the conveyor belt 3 to transmit on several transmission rollers 2, so as to facilitate the transportation of the paper on the conveyor belt 3. The second servo motor 19 drives the first rotating shaft 4 to rotate, and the first rotating shaft 4 realizes the rotation of the first cam 5 and the second cam 6.
