[0033] In some embodiments, the second pulley 82 is fixedly connected to the transmission shaft 7 .

[0034] Specifically, the driving motor 8 drives the first pulley 81 to rotate, thereby synchronously transmitting the second pulley 82 to drive the transmission shaft 7 to rotate. The transmission shaft 7 and the driving motor 8 are coordinated to transport materials. The setting of the eccentric block 71 improves the transportation efficiency, and the feeding amount is increased by utilizing the movement coordination of the two eccentric blocks 71 at an angle to each other.
