[0033] The automatic discharging compression component is arranged on the inner wall of the extrusion box 1.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The vibrating unloading assembly includes a motor 5 fixedly connected to the inner wall of the feed box 2, and a rotating block 6 is fixedly connected to the output end of the motor 5. The outer wall of the rotating block 6 is rotatably connected to an L-shaped rod 7.

Two groups of short sliders 8 are symmetrically arranged. The outer wall of the short slider 8 is fixedly connected to a vibration box 9. The rotating block 6 is driven to rotate by the output end of the motor 5, and then the end of the L-shaped rod 7 is driven to follow the rotation and then pull the short slider 8 to slide up and down in the feed box 2, thereby driving the vibration box 9 to shake up and down, so that the unloading box unloads and enters the inside of the extrusion box 1 through the guide box 15. The inner wall of the vibration box 9 is fixedly connected with staggered inclined plates 11. The inclined plates 11 extend the moving distance of the raw materials, so that there is sufficient time for heating and drying.
