[0039] In this embodiment, a limiting rod is fixedly connected to the right side of the slide plate 5. The limiting rod passes through the contact plate 7. The limiting rod is used to limit the contact plate 7 so that the contact plate 7 can move laterally stably.

[0044] Working principle: In actual use, by feeding materials into the barrel 1, during the material conveying process, preheating, stirring, mixing, and before plasticization, part of the moisture and small molecular volatiles in the material are removed through the exhaust port 2. After passing through the exhaust port 2, the material is partially melted. On this basis, the pre-treated wood powder is fed into the feed hopper 3, and then continued to be stirred, mixed, and melted. The moisture contained in the molten material and other volatile components are forcibly pumped out by the vacuum pump 27. Excessive moisture and volatile content will affect the mechanical properties and appearance of the product. When the feed amount of the feed hopper 3 needs to be adjusted, first push the contact plate 7 to move left. When the contact plate 7 moves, it will compress the push spring 8. At the same time, when the contact plate 7 moves, it will push the push rod 9. When the push rod 9 moves, it will push the positioning rod 10 upward. At this time, the positioning rod 10 moves out of contact with the positioning groove to unlock the slide plate 5. At this time, the slide plate 5 can be pushed to move horizontally, thereby driving the baffle 4 to move horizontally and the feed hopper 3 to gradually lose the restriction, so that the material in the feed hopper 3 enters the barrel. 1. When the baffle plate 4 moves to a suitable position, the contact plate 7 is released, and the push spring 8 loses its restriction and pushes the contact plate 7 to move right and reset. The contact plate 7 pulls the push rod 9 to make the positioning rod 10 move down and reset to engage with the positioning groove. At this time, the slide plate 5 and the baffle plate 4 can be fixed at the current position, and the processed material will be discharged from the discharge tray 13. The inner wall of the discharge tray 13 is provided with a plurality of discharge holes at equal intervals. The material will be squeezed out from the discharge holes. At this time, the motor 15 is started, and the rotation of the output shaft of the motor 15 will drive the cutting knife 16 to rotate to cut the material, and the material is cut into particles. The material will fall onto the discharge hopper 14, and the material will be cooled by starting the fan 17. When the discharge tray 13 needs to be replaced, the push plate 18 is first pushed to move left. When the push plate 18 moves, it will drive the cross plate 19 to move left. At this time, the movement of the cross plate 19 will compress the reset spring 20, and at the same time, the cross plate 19 drives the cross bar 22 to move left. When the cross bar 22 moves, it will pull the pull rod 23. At this time, the movement of the pull rod 23 will pull the lifting plate 24 upward. The upward movement of the lifting plate 24 will compress the positioning spring 25, and at the same time, the movement of the lifting plate 24 will drive the card block 26 to move up and disengage from the card slot. At this time, the fixing buckle 12 can be unlocked, and the discharge tray 13 can be removed. The appropriate discharge tray 13 is placed on the right side of the barrel 1, and the fixing buckle 12 is inserted into the fixing box 11. At this time, the push plate 18 is released, and the reset spring 20 loses its restriction and pushes the cross plate 19 to move horizontally and reset. The reset of the cross plate 19 will drive the push plate 18 and the cross bar 22 to move left and reset. The positioning spring 25 loses its restriction and pushes the lifting plate 24 downward. At this time, the card block 26 engages with the card slot to fix the fixing buckle 12, thereby fixing the discharge tray 13 and achieving the effect of replacing the discharge tray 13.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
