[0033] In this embodiment, the feeding mounting frame 11 and the feeding support frame 12 are fixed to the ground or the production line base through bolts, ensuring that the feeding mounting frame 11 is vertical and the feeding support frame 12 is at an inclined support angle. The feeding assembly is installed by embedding the feeding hopper 21 into the feeding mounting frame 11 and welding it, the cover 22 is installed on the top of the feeding hopper 21 through a hinge, and the discharge cylinder 24 is welded to the bottom of the feeding hopper 21.

[0034] In this embodiment, the connection pipe 31 is connected with the discharge cylinder 24 through a flange, and then the feeding pipe 32 is assembled in sections: the butt joint block 43 of each section of the feeding pipe 32 is inserted into the butt joint groove 42 of the next section to form axial positioning, and then the fixing sleeve 38 is tightened to complete the thread fastening. The end of the feeding pipe 32 is connected with the head pipe 33 in the same way, the head pipe 33 is installed with a rotating sleeve 34 at the top, and the discharge pipe 36 is welded to the side of the head pipe 33.

[0035] Specifically, the spiral feeding rod 35 is inserted from the discharge cylinder 24 of the feeding hopper 21, sequentially passes through the connection pipe 31, the multi-section feeding pipe 32, and finally is inserted into the rotating sleeve 34 of the head pipe 33, and is connected with the feeding motor 37 through a shaft coupling.

[0038] Referring to Figures 1-2 , the top of the feeding hopper 21 is provided with a cover 22, one side of the cover 22 is fixed to one side of the top of the feeding mounting frame 11 through a hinge, and a handle 23 is further arranged on the cover 22, the bottom of the feeding hopper 21 extends with a discharge cylinder 24, one side of the discharge cylinder 24 is connected with a connection pipe 31, and the end of a spiral feeding rod 35 is placed in the discharge cylinder 24, and a feeding motor 37 drives the spiral feeding rod 35 to rotate.

[0039] Specifically, the feeding support frame 12 is connected to one side of the feeding mounting frame 11, and the outer wall of the feeding pipe 32 leans against the feeding support frame 12 and is arranged at an inclined angle.

[0040] In this embodiment, the cover 22 is opened, and the recycled plastic particles are put into the hopper 21, and the cover is closed to prevent dust. The feeding motor 37 is started, and the spiral feeding rod 35 is driven to rotate.

[0043] Specifically, the inclined support of the feeding support frame 12 allows the conveying inclination to be adjusted to match different heights of processing equipment.

[0044] In this embodiment, the axial positioning of the butt joint assembly 4 + the radial locking of the fixed pipe sleeve 38 reduces the running vibration and prolongs the service life of the motor. Only the damaged section of the feeding pipe 32 needs to be replaced or the specific area needs to be cleaned, so the maintenance time is shortened and the cost is reduced.

[0045] In this embodiment, the sealing design of the hopper cover 22 and the pipe connection part reduces the amount of dust escaping, meeting the environmental protection requirements. The anti-slip pattern 39 of the fixed pipe sleeve 38 provides high friction to prevent the risk of slipping during disassembly and assembly, causing work injury. Impurities or uneven humidity containing recycled plastics can be conveyed, and the rotation speed of the spiral feeding rod 35 is adjusted to adapt to the flowability of different materials.
