The waste plastic recycling, crushing and collecting device controls the scraper sealing plate to extend outward through an electric telescopic rod, and then starts the servo motor, and drives the loading frame to move upward through the servo motor. During the process of the loading frame rising, the scraper sealing plate abuts against the inner wall of the loading frame, and then the electric telescopic rod is started to recycle the scraper sealing plate. During the process of reclaiming the scraper sealing plate, the waste plastic inside the loading frame is scraped into the inside of the crusher body and crushed, thereby improving the convenience of loading the device and reducing manpower consumption.

[0016] Secondly, the utility model allows the waste plastics that have been initially shredded to enter the crushing box, so that the crushing effect is better and the waste plastics are prevented from being too large in size and affecting the crushing efficiency. Then, the second motor is started to drive the crushing roller to rotate, so that the waste plastics are crushed into particles again. Then, the crushed waste plastics are screened through the screening net, so that qualified waste plastics pass through the screening net, and unqualified waste plastics slide into the interior of the auger, and are re-transmitted to the discharge pipe through the auger, and are discharged into the crushing box again through the discharge pipe until they can pass through the screening net, thereby completing the crushing operation.
