[0032] Reference Figure 6 The inner cavity of the fixed box 508 and both sides of the adjusting block 511 are provided with second springs 516. The two sides of the second springs 516 are fixedly connected to the push plate 509 and the fixed box 508 respectively. By providing the second springs 516, the two push plates 509 can be moved to the middle for reset.

[0033] Working principle: Material is fed into the crushing chamber 4 through the feed shell 13. The motor 9, in conjunction with the rotating rod 10, drives the crushing blade 14 to rotate and crush the material. The crushed material is then screened out through the screen plate 501. Simultaneously, the rotating rod 10 drives the cam 502 to rotate, which in turn pushes two push blocks 510 away from each other. The push blocks 510, through the cooperation of the push plate 509 and the adjusting block 511, cause the tops of the two adjusting frames 512 to move away from each other. The bottom of the adjusting frame 512 moves upward, causing the lifting plate 507 to move upward. The lifting plate 507, through the cooperation of the lifting sleeve 506, the lifting block 505, and the lifting frame 503, moves the screen plate 501 upward. When the cam 502 releases its pressure on the push blocks 510, the screen plate 501 moves downward to reset due to gravity. The cam 502 will move towards the center to reset, and the continuous rotation of the cam 502 will cause the screen plate 501 to vibrate up and down, thereby improving the screening efficiency of the material and enabling the crushed material to be quickly separated from the uncrushed material, thus accelerating the production efficiency of the continuous production line for the preparation of waste plastic recycled granules. The user can rotate the screw 604 by using the handwheel 605. The rotation of the screw 604 can drive the screw sleeve 606 to adjust the height. The screw sleeve 606 can drive the baffle 601 to adjust the height through the connecting frame 607. The baffle 601 can close the discharge shell 11 when it moves downward, and it can release the material when it moves upward. At this time, the material in the crushing box 4 will enter the feed hopper 12 through the discharge shell 11. The material will enter the granulator 2 through the feed hopper 12. The granulated material will move to the right and enter the cooling device 3 for cooling, thus completing the preparation of waste plastic recycled granules.
