[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0022] like Figure 1-4 As shown, the utility model proposes a device for processing and recycling plastic waste, comprising:

[0023] A processing tank 1 is provided, wherein a feeding hopper 3 is connected to one side of the top of the processing tank 1, a heating cylinder 2 is sleeved on the outer side of one end of the processing tank 1 connected to the feeding hopper 3, a rotating shaft 4 is passed through the inner side of the processing tank 1, and a circular and equidistantly arranged oblique curved blade 5 is fixed to the outer side of one end of the rotating shaft 4 close to the feeding hopper 3, and a circular equidistantly distributed crushing knife 6 is fixed to the outer wall of the other end of the rotating shaft 4, and the ends of the crushing knife 6 located at both ends of the outer side of the heating cylinder 2 are rotatably connected to a pressing shaft 7, and a discharge pipe 8 is connected to the bottom of the processing tank 1 directly below the pressing shaft 7, and the outer surface of the pressing shaft 7 rolls in contact with the inner wall of the processing tank 1, and rolls on the outer surface of the discharge pipe 8 at the same time.

[0024] A recovery box 9 is provided at the bottom end of the discharge pipe 8 , and the bottom surface of the discharge pipe 8 is connected to the inside of the recovery box 9 .

[0025] The top surface of the recovery box 9 is located just below the heating cylinder 2 and is fixed with two symmetrical groups of support columns, and the top ends of the support columns are fixed to the bottom surface of the heating cylinder 2.

[0026] A heating chamber 10 is provided inside the heating cylinder 2 , and circularly distributed heating tubes 11 are inserted into the heating chamber 10 .

[0027] A driving motor 13 is fixed at the center of one end of the processing tank 1 , and an output end of the driving motor 13 is drivingly connected to the rotating shaft 4 .

[0028] In this embodiment, the heating cylinder 2 can heat the inside of the processing tank 1 to soften the plastic for easy cutting. The inclined blade 5 can use the inclined blade design to transport the plastic during the cutting process, while the curved blade can cut the plastic. The blade design can blow the plastic to accelerate the speed of transporting the plastic to the other side.

[0029] The position design of the crushing knife 6 allows the plastic conveyed to be continuously cut and crushed in this area. When the cut fragments are in a smaller position, they will be discharged through the storage pipe. At the same time, after the large particles are heated and softened, the pressing shaft 7 will slide on the top of the processing tank 1 and the storage pipe driven by the rotating shaft 4, pressing the large particles of plastic to complete the discharge.

[0030] Usage process: the plastic passes through the hopper 3 and enters the inclined blade curved knife area inside the processing tank 1. After being cut by the inclined blade curved knife, the plastic bottles and plastic products become fragments. At this time, the plastic will be scraped to one side by the inclined blade. While the plastic moves, the heating bin 10 will heat and soften the plastic. As the plastic continues to move, it will also be continuously cut and transported by the inclined blade curved knife blade 5 until the plastic is transported to the position of the crushing knife 6. The crushing knife 6 will continuously cut and crush the plastic transported to the inside, and at the same time drive the pressing shaft 7 to transport the plastic particles to the inside of the storage tube, completing the processing and recycling of the plastic. The processed plastic will be recycled to the inside of the recycling box 9 to complete the collection. Example

[0031] like Figure 1-4 As shown, based on the first embodiment, a heat insulating chamber 12 is provided on the outside of the heating chamber 10 , and the heat insulating chamber 12 is located between the inner wall of the heating cylinder 2 and the heating chamber 10 .

[0032] A discharge hole 14 is provided at the position where the top surface of the discharge pipe 8 is connected to the processing tank 1 , and the top surface of the discharge hole 14 is in close contact and sliding connection with the pressing shaft 7 .

[0033] In this embodiment, the heat-insulating chamber 12 can improve the heating efficiency inside the processing tank 1, reduce the heat released to the outside, and also prevent the heating position of the processing tank 1 from overheating.

[0034] The design of the discharge hole 14 can block plastic with larger particles. At the same time, the cooperation between the discharge hole 14 and the pressing shaft 7 can allow the plastic with large particles to be crushed into the discharge hole 14 to form small particles of plastic to complete the discharge.

[0035] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
