The servo motor 8 drives the threaded rod 9 to rotate in the opposite direction. The threaded rod 9 drives the movable plate 11 and the sliders 28 on both sides of the movable plate 11 to move downward along the track of the slide groove 29 through the threaded cylinder 10. While the movable plate 11 moves downward, on the one hand, it drives the stirring rod 15 and the hollow sleeve 26 to gradually move downward, and on the other hand, it drives the connecting rod 21 to move downward. The connecting rod 21 drives the rotating rod 18 to rotate on the limit shaft 17 through the connecting plate 20 and the rotating plate 19. The rotating plate 19 rotates within a certain range to gradually release the raw materials in the mixing box 5, so that it enters the extruder body 2 through the feed hopper 3, so as to achieve the effect of discharging while stirring, thereby improving work efficiency.
