The left and right sides of the outer wall of the drum screen 8 are fixedly connected to the ring gear 13, and the bottom end of the outer edge of the ring gear 13 is meshed with the top end of the outer edge of the first gear 14. The front and rear sides of the inner wall of the equipment casing 1 are rotatably connected to the support gear 12, and the left and right sides of the outer wall of the drum screen 8 are fixedly connected to the ring gear 13, and the front and rear sides of the outer edge of the ring gear 13 are respectively meshed with the opposite end of the outer edge of the support gear 12. An observation window 4 is fixedly connected to the front end of the equipment casing 1, and the four corners of the bottom end of the equipment casing 1 are fixedly connected to the support legs 5.

[0029] Specifically, a controller is provided at the front end of the equipment housing 1. The controller can independently control the operation of the motor 6, the fan 11 and the hydraulic rod 21. The guide rail can guide the waste plastic into the drum screen 8 without spilling it out. The speed limit plate 16 is in the shape of a semicircle and is arranged in such a way that it rotates at a certain angle, so that the incoming waste plastic will be discharged into the next groove. Before the waste plastic enters the drum screen 8 from the pounding trough, the motor 6 is turned on.

The top of the left end of the first support plate 19 is rotatably connected to a hydraulic rod 21, and the driving end of the hydraulic rod 21 is rotatably connected to the connecting rod 20. The right end of the connecting rod 20 is rotatably connected to the bottom end of the first support plate 19, and the top of the first support plate 19 is rotatably connected to the second support plate 22. The driving end of the hydraulic rod 21 is slidably installed on the inner wall of the second support plate 22, and the weighing plates 10 are fixedly connected to the top of the second support plate 22

[0031] Specifically, the display screen of the controller is connected to the weighing plate 10, so that the waste plastic on the weighing plate 10 can be weighed. The waste plastic is added from the feed port 2 and falls onto the weighing plate 10 for weighing. After the weighing is completed, the controller is used to start the hydraulic rod 21. The hydraulic rod 21 will extend and then flip the second support plate 22 downward, thereby driving the weighing plate 10 to flip. The flipping directions of the weighing plates 10 on both sides are different, so that a channel will be opened in the middle, and the waste plastic will be discharged into the equipment housing 1 for air separation.

[0032] Working principle: Add waste plastic from the feed port 2 and let it fall onto the weighing plate 10. The weighing plate 10 will weigh it and display it on the controller. When it reaches the appropriate weight, use the controller to start the hydraulic rod 21. The hydraulic rod 21 will extend and push the connecting rod 20 to move, thereby flipping the connecting rod 20 downward, thereby driving the second support plate 22 to flip downward, and then opening the weighing plate 10 and allowing the waste plastic to enter the equipment housing 1. When the hydraulic rod 21 is opened, the motor 6 is turned on at the same time. The motor 6 will drive the second roller 17 and the drive gear 7 to rotate, so that the second roller 17 drives the speed limit plate 16 to rotate, and the drive gear 7 drives the second gear 18 to rotate. The second gear 18 will also drive the first roller 15 to rotate, and the first roller 15 drives the first gear 1 4 rotates, thereby driving the gear ring 13 to rotate, and the gear ring 13 will drive the drum screen 8 to rotate. At this time, the drum screen 8 will rotate with the speed limit plate 16. At this time, the waste plastics will enter the drum screen 8 under the action of the material guide trough, and will pass through each speed limit plate 16, thereby slowing down the passing speed, and will be flipped under the rotation of the drum screen 8, thereby increasing the contact time and effective contact area with the drum screen 8, thereby improving the quality of air separation. The materials that have passed through the drum screen 8 and been screened will be discharged from the discharge port 9 at the bottom of the equipment housing 1, thereby completing the classification, and the fan 11 will be turned on together with the motor 6 to provide wind power, which can enable the waste plastics to smoothly enter the drum screen 8 to complete the air separation, and again through the action of the weighing plate 10, new waste plastics will enter the drum screen 8 for air separation, and this cycle will be repeated.
