The top end of the support block 31 is fixedly connected with a feeding box 32. The support block 31 is used to support the feeding box 32.

[0039] The bottom end of the crushing box 1 is fixedly connected with a centralized material conveying pipe 18. The bottom end of the centralized material conveying pipe 18 is fixedly connected with a cleaning device 38. The centralized material conveying pipe 18 is used to convey the crushed plastic to the cleaning device 38. The bottom end of the cleaning device 38 is fixedly connected to the bottom inner wall of the working box 19. The cleaning device 38 is responsible for cleaning the crushed plastic. The right end of the cleaning device 38 is fixedly connected with a material conveying pipe 39. The outside of the material conveying pipe 39 is fixedly connected with a drying device 40.

The discharge pipe 42 is used to discharge the finally processed plastic out of the working box 19. The four corners of the bottom end of the working box 19 are all fixedly connected with support feet 43 to provide stable support for the entire device.

[0040] Working principle: When the plastic is broken by the crushing roller 29, it falls onto the sieve plate 15 under the action of the inclined plate 16. By starting the double-headed motor 3 to generate power and drive the sector circular plate 12 to rotate, due to the unique design of the sector circular plate 12, a centrifugal force will be generated during rotation. Then, this centrifugal force is used to drive the protective shell 4 to perform circular motion in the up, down, left, and right directions. Through the action of the first spring 5 and the second spring 10, most of the motion of the protective shell 4 is transmitted to the connecting plate 13. Through the motion of the connecting plate 13, the motion of the transmission rod 14 is driven, realizing that the motion of the transmission rod 14 drives the sieve plate 15 to move, achieving the vibration transmission of the plastic on the sieve plate 15. Thus, the qualified crushed plastic enters the discharge cylinder 17, and the unqualified crushed plastic enters the material collection box 36 through the discharge cylinder 17. Then, the unqualified crushed plastic collected in the material collection box 36 is put into the feeding box 32. The driving motor arranged at the bottom of the feeding pipe 33 drives the feeding shaft 34 to drive the spiral blade 35 to rotate, realizing the re-transportation of the unqualified crushed plastic to the feeding port 30 for re-crushing. Thereby, the uniformity and quality of the recycled plastic are effectively improved, ensuring that the final product has better physical properties. At the same time, the efficiency of the equipment is also improved and the maintenance cost is reduced.

[0041] By turning on the fan 24 to generate power and drive the gas flow inside the working box 19, the gas in the working box 19 is realized to enter the connecting pipe 20 through the air inlet hood 23, the air inlet pipe 22 and the circular plate 21, and then enter the purification box 26 through the fan 24 and the gas transmission pipe 25. The waste gas is purified by the action of the purification box 26, and the purified gas is discharged through the air outlet pipe 27. The waste gas generated during the plastic processing process includes volatile organic compounds (VOCs), particulate matter and harmful gases. These pollutants can be removed through an effective purification system, reducing their impact on the surrounding environment and protecting the air quality.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
