When the machine body 2 tilts upward, the reciprocating frame 29 uses the bracket 30 to drive the roller 31 to move synchronously to the right side, so that the roller 31 squeezes the traction rope 32, further improving the pulling effect of the traction rope 32, so as to expand the tension of the traction rope 32 according to actual needs, to ensure that the sealing plate 23 can tightly seal the material frame 3, so that the sealing plate 23 inside the material frame 3 can swing downward and seal the material frame 3.

During the processing, the transmission motor drives the shaft 16 to rotate continuously, and the shaft 16 drives the wheel 17 to rotate synchronously and uses the rubber rod 18 on the back to repeatedly hit the wave plate 19. The wave plate 19 is hit and hit by the rubber rod 18 and generates vibration force, which is transmitted to the inside of the machine body 2, so that the material attached to The raw materials on the surface of the conveying rod are separated from the sticky state.
