The pusher block 171 is movable at the top opening of the extruder body 2.

[0040] Specifically, when the filter shell 5 swings up and down relative to the feeding box 4, the filter shell 5 drives the pusher block 171 to move up and down through the connecting rod 17, so that the pusher block 171 pushes down the material at the top opening of the extruder body 2, avoiding the accumulation of material at the connection port between the extruder body 2 and the feeding box 4, ensuring that the material distribution in the granulation equipment is uniform, thereby improving the uniformity of material melting and the continuity of material extrusion.

[0041] Working principle: Recycled plastic material containing polytetrafluoroethylene propylene is fed into the filter housing 5 through the feed pipe 501. Large particles of material are intercepted by the filter plate at the bottom of the filter housing 5, while small particles of material enter the extruder body 2. By controlling the operation of the drive motor 8, the output shaft of the drive motor 8 drives the drive shaft 801 to rotate. When the drive shaft 801 rotates, it drives the first connecting plate 802 to rotate. The first connecting plate 802 drives the second connecting plate 803 to move. The lower side of the second connecting plate 803 moves around the fixed shaft 804 as the center point, causing the second connecting plate 803 to push the filter shell 5 to shake up and down relative to the feeding box 4, thereby causing the small particles of material that fall on the filter plate at the bottom of the filter shell 5 to fall quickly. When the filter housing 5 swings up and down relative to the feeding box 4, the filter housing 5 drives the pusher block 171 to move up and down through the connecting rod 17, so that the pusher block 171 pushes down the material at the top opening of the extruder body 2, avoiding the accumulation of material at the connection port between the extruder body 2 and the feeding box 4. When the driving shaft 801 rotates, the main gear 16 meshes with the pinion 132 at one end of the rotating pipe 13 to drive the rotating pipe 13, so that the stirring filter plate 131 moves between the outer wall of the feeding pipe 6 and the inner wall of the filter shell 5, and the stirring filter plate 131 stirs the large particle materials accumulated on the lower side of the filter shell 5 upward. When the stirring filter plate 131 rotates and approaches one end of the feeding pipe 6, the large particle materials stirred by the stirring filter plate 131 slide down along the inclined surface of the stirring filter plate 131, and then enter the feeding pipe 6 through the feeding port 601. When the rotating pipe 13 rotates, the pinion 132 at the other end meshes with the main gear 16 on the rotating shaft 11 to drive the rotating shaft 11 to rotate through the synchronous wheel 12 and the synchronous belt, so that the conveying shaft 10 rotates to drive the spiral conveying blade 1001 to rotate in the feeding pipe 6, and the spiral conveying blade 1001 conveys the large particle plastic materials entering the feeding pipe 6; The materials falling from the opening of the feeding pipe 6 enter the crushing box 7. When the filter shell 5 reciprocates up and down relative to the feeding box 4, the upper shell body 701 and the lower shell body 702 move away from each other, and the flexible connecting piece 703 is automatically stretched to adapt to the change in distance between the upper shell body 701 and the lower shell body 702. When the second connecting plate 803 swings, the crushing block 8031 swings left and right in the lower shell body 702 to crush the large particle materials passing through the lower shell body 702, and the small particle materials after the crushing process are poured into the filter shell 5 again through the feeding pipe 501. The extrusion motor 3 drives the speed reducer 301 to rotate, so that the speed reducer 301 drives the double-screw extrusion structure in the extrusion body 2 to work to convey and extrude the materials entering the extrusion body 2.

[0042] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
