Currently, my country's waste plastics primarily include plastic film, plastic yarn and woven fabrics, foam plastics, plastic packaging and containers, household plastic products, plastic bags, and agricultural mulch. As the consumption of plastic products continues to grow, so too does the amount of waste plastic. Furthermore, my country's annual consumption of plastics for automobiles has reached 400,000 tons, and that for electronic and electrical appliances has reached over 1 million tons. These discarded products have become a significant source of plastic waste.

[0020] Through the cooperation of the isolation plate 401 and the water trough 402, when the device is in use, the interior of the cleaning tank body 101 can be divided into two inner and outer areas through the isolation plate 401. When the device pours the crushed waste plastic into the cleaning tank body 101 through the feed port 112, the waste plastic will be cleaned in the outer area of the cleaning tank body 101. Then, the cleaned waste plastic will enter the inner area of the cleaning tank body 101 through the water trough 402 and be discharged from the device through the drain port 103. At this time, the water trough 402 will be blocked by the telescopic baffle 501, thereby preventing the waste plastic in the outer area from entering the inner area, so that the device can avoid discharging the uncleaned waste plastic when cleaning the waste plastic, thereby improving the cleaning efficiency.

[0021] The cleaning mechanism 1 includes a cleaning tank body 101, a cleaning tank cover 102, a circulating water inlet 104, a motor mounting bracket 105, a servo motor 106, a support bracket 107 and a feed port 112.

At this time, the water in the inner area will be discharged into the interior of the circulating water tank 201 through the drain port 103, and due to the obstruction of the filter plate 109, the solenoid valve 205 controls the discharge pipe 203 to discharge the dirty water through the discharge pipe 203, so that the waste plastic will not enter The interior of the circulating water tank 201 is used to realize the water change operation inside the cleaning tank body 101, thereby avoiding affecting the cleaning of waste plastics during water change or discharging waste plastics together. At the same time, when the waste plastics are cleaned, the movable telescopic block 404 at the bottom of the lever 403 can be used to push the pushing arc plate 110 on the surface of the filter plate 109, so that the filter plate 109 moves to the other side position inside the arc groove 108, so that the filter plate 109 no longer blocks the drain outlet 103. At this time, water and waste plastics will be discharged into the interior of the circulating water tank 201 at the same time, so that the waste plastics and water can be discharged at the same time through the discharge pipe 203, thereby facilitating the subsequent processing of the waste plastics.

[0025] The scraping mechanism 3 includes a piston cylinder 301, an outer scraper 302, an inner ring scraper 303 and a connecting plate 304. Four piston cylinders 301 are fixedly installed on the top of the cleaning tank cover 102. The output ends of the piston cylinders 301 are fixedly connected to the connecting plate 304. The outer scraper 302 is fixedly installed on one side of the connecting plate 304, and the inner ring scraper 303 is fixedly installed on the other side of the connecting plate 304.

[0026] The adjusting mechanism 5 includes a telescopic baffle 501, an L-shaped connecting rod 502, a telescopic groove 503, a spring groove 504 and an extrusion spring 505. The inner wall surface of the water trough 402 is provided with a telescopic groove 503. The inside of the telescopic groove 503 is slidably installed with a telescopic baffle 501. The end of the telescopic baffle 501 is fixedly installed with an L-shaped connecting rod 502. The inner side of the telescopic groove 503 is provided with a spring groove 504. The telescopic groove 503 is slidably inserted into the inside of the spring groove 504. An extrusion spring 505 is movably installed between the telescopic groove 503 and the inside of the spring groove 504. One end of the extrusion spring 505 is connected to the inner wall of the spring groove 504, and the other end of the extrusion spring 505 is connected to the telescopic groove 503.

[0027] The adjusting mechanism 5 also includes a pushing slot 506, a pushing electromagnet 507, a pushing rod 508 and a mounting rod 509. The telescopic slots 503 are all provided with pushing slots 506. The pushing electromagnets 507 are fixedly installed inside the pushing slots 506. The output ends of the pushing electromagnets 507 are fixedly connected to the mounting rods 509. The ends of the mounting rods 509 are all fixedly installed with pushing rods 508. The pushing rods 508 are all in contact with the surface of the telescopic baffle 501.

[0028] The surfaces of the movable telescopic block 404 , the telescopic baffle 501 and the push rod 508 are all provided with inclined surfaces 6 , and the outer ends of the telescopic baffle 501 are all movably inserted into the interior of the water trough 402 .

[0029] The bottom surface of the lever 403 is provided with a plurality of flexible brushes, which are all in contact with the top surface of the filter plate 109 . The output end of the servo motor 106 is connected to the rotating shaft 406 via a coupling.

[0030] The end of the circulating water pipe 204 is movably connected to the circulating water port 104 , the outer scraper 302 is in contact with the inner wall surface of the cleaning tank 101 , and the inner scraper 303 is in contact with the outer surface of the isolation plate 401 .

[0031] When the waste plastic recycling and processing device is in use, first add an appropriate amount of cleaning water to the inside of the cleaning tank 101 through the feed port 112, and pour the crushed waste plastic into the inside of the cleaning tank 101 through the feed port 112. At this time, the servo motor 106 drives the rotating shaft 406 to rotate forward, and the rotating shaft 406 drives the fixed rod 405 and the isolation plate 401 to rotate, thereby stirring the cleaning water inside the cleaning tank 101, thereby cleaning the waste plastic. When the waste plastic is cleaned, the push electromagnet 507 can be closed to retract the output. The push rod 508 is retracted from the inside of the telescopic groove 503, so that it no longer blocks the telescopic baffle 501. At this time, the telescopic baffle 501 is retracted into the inside of the telescopic groove 503 by the elastic force of the extrusion spring 505, thereby opening the position of the water channel 402. At the same time, the water inside the drain port 103 is sucked in through the circulating water tank 201 and discharged back into the interior of the cleaning tank body 101 through the circulating water pipe 204. The waste plastic is attracted by the water from the drain port 103 in the cleaning tank body 101, so that it passes through the water channel 402 and enters the inner position of the isolation plate 401; When the waste plastic enters the inner side of the isolation plate 401, the push electromagnet 507 is activated to push the push electromagnet 507 out of the output end, thereby causing the push rod 508 to be stuck in the telescopic groove 503, thereby pushing the telescopic baffle 501 outward through the inclined surface 6 on its surface, thereby blocking the water channel 402 through the telescopic baffle 501. At this time, waste plastic can continue to be added to the cleaning tank body 101 through the feed port 112, so that the waste plastic in the two areas inside and outside the cleaning tank body 101 can be cleaned simultaneously; When the waste plastics in the inner area are cleaned, the servo motor 106 can be used to drive the shaft 406 to rotate in the opposite direction. At this time, the lever 403 will drive the movable telescopic block 404 to rotate to the position of the filter plate 109, so that the side of the movable telescopic block 404 without the inclined surface 6 collides with the surface of the pushing arc plate 110, thereby pushing the filter plate 109 to move inside the arc groove 108, so that the filter plate 109 moves from the position of the drain outlet 103 to the innermost position of the arc groove 108. At this time, the filter plate 109 is not Then, the drain port 103 is blocked, so that the water sucked into the circulating water tank 201 from the drain port 103 will discharge the waste plastics in the area inside the cleaning tank body 101 into the interior of the circulating water tank 201 through the drain port 103. At the same time, the solenoid valve 205 controls the circulation water pipe 204 to be closed, so that the discharge pipe 203 is opened, so that the waste plastics after cleaning are discharged through the discharge pipe 203 to the subsequent processing position. At the same time, the water is changed through the feed port 112 to clean the waste plastics outside the cleaning tank body 101. When all the waste plastics in the inner area are discharged through the drain outlet 103, the servo motor 106 drives the rotating shaft 406 to rotate forward again. At this time, the lever 403 drives the movable telescopic block 404 to hit the surface of the pushing arc plate 110 of the filter plate 109. At this time, the movable telescopic block 404 will retract to the inside of the lever bottom groove 407 due to the contact between the inclined surface 6 and the surface of the pushing arc plate 110, so that the lever 403 passes the upper position of the filter plate 109. At the same time, when the movable telescopic block 404 hits the pushing arc plate 110, the pushing arc plate 110 is forced to move in the opposite direction of the drain outlet 103. After repeated impacts by the movable telescopic block 404, the filter plate 109 will return to the position of the drain outlet 103, thereby blocking the position of the drain outlet 103 and preventing the plastic from leaking through the drain outlet 103. When the lever 403 rotates, the flexible brush at its bottom rotates synchronously, thereby brushing away the waste plastic on the surface of the filter plate 109 to prevent it from adhering to the surface of the filter plate 109 and affecting the water circulation. During cleaning, the piston cylinder 301 can be used to drive the output end to perform reciprocating motion, thereby controlling the connecting plate 304 to drive the outer scraper 302 and the inner scraper 303 to perform lifting motion inside the cleaning tank body 101, and then the outer scraper 302 and the inner scraper 303 can be used to scrape the waste plastic attached to the inner wall of the cleaning tank body 101 and the outer surface of the isolation plate 401 respectively, so that it leaves the inner wall of the cleaning tank body 101 and the outer surface of the isolation plate 401.
