The wall is inserted into the four limiting blocks 55. Each of the two side plates 42 has a slot 43 on one opposite side. A guide plate 44 is provided at one end of each slot 43. The inner walls of the two slots 43 are inserted into the two insert plates 53. A fixing beam 411 is fixedly connected to the middle of the fixing frame 41. Two fixing grooves 412 are provided at the top of the fixing beam 411. The fixing member 56 includes two fixing blocks 566, which are respectively inserted into the inner walls of the two fixing grooves 412. The top of each fixed block 566 is fixedly connected to a movable tube 565. One end of each movable tube 565 is fixedly connected to a tension spring 564. The ends of each tension spring 564 away from the movable tube 565 are fixedly connected to a storage tube 561. A rotating wheel 562 is rotatably connected to the opposite side of the two storage tubes 561. Threaded rods 563 are fixedly connected to both sides of the rotating wheel 562. The threaded rods 563 pass through the outer wall of one end of the storage tube 561 and are threadedly connected to the movable tube 565.

[0018] It should be noted that when disassembling and repairing the screen 5, the operator rotates the rotating wheel 562, causing the threaded rod 563 to rotate and make threaded movement with the movable tube 565. Through the movable tube 565, the fixed block 566 is driven to disengage from the fixed groove 412 and enter the movable groove 410. Then, the motor 46 is started, causing the movable plate 48 to move the screen 5 to one end of the vibrating frame 4. The insert plate 53 disengages from the inner wall of the slot 43, and the operator can then remove the screen 5 for maintenance. After maintenance is completed, the screen body 52 is placed on one end of the top of the fixed frame 41, so that the fixing part 56 is inserted into the movable groove 410. The insertion plate 53 is positioned at the bottom of the guide plate 44. Then, the motor 46 can be started, causing the movable plate 48 to move the screen 5 until the four limit blocks 55 are inserted into the four limit slots 45 respectively, and the insertion plate 53 is fully inserted into the slot 43. Finally, the rotating wheel 562 can be rotated to make the threaded rod 563 and the movable tube 565 make threaded movements. The movable tube 565 slides in the inner wall of the receiving tube 561, causing the fixing block 566 to disengage from the movable slot 410 and insert into the inner wall of the fixing slot 412 for fixation. The tension spring 564 prevents loosening, thus realizing the quick installation of the screen 5 and facilitating the operation of the staff.

[0019] A movable plate 48 is slidably connected to the bottom of the fixed beam 411. A movable groove 410 is provided on the top of the movable plate 48. When the screen 5 needs to be removed, the rotating wheel 562 can be rotated to make the fixed block 566 disengage from the fixed groove 412 and insert into the inner wall of the movable groove 410. A motor 46 is fixedly connected to one end of the fixed frame 41. A threaded rod 47 is fixedly connected to the output end of the motor 46. The outer wall of the threaded rod 47 is threadedly connected to the movable plate 48. A brush bristle 49 is fixedly connected to the top of the movable plate 48.

[0020] It should be noted that the operator starts the vibrator 2 to drive the vibrating frame 4 to vibrate on the support frame 1 through the vibrating components. The vibrating frame 4 drives the screen 5 to vibrate, and plastic particles are put into the screen 5. Smaller plastic particles pass through the screen body 52 and fall into the bottom collection tray 3 for collection and discharge into the recycling device. Larger plastic particles remain on the top of the screen body 52 and are finally collected in the top collection tray 413 and discharged into the recycling device. When plastic particles adhere to the bottom of the screen body 52 or block the inside of the screen body 52 mesh, the motor 46 can be started to drive the threaded rod 47 to rotate. The threaded rod 47 and the movable plate 48 make a threaded movement, which drives the bristles 49 to clean the plastic particles accumulated and blocked on the screen body 52, reducing manpower waste and improving work efficiency.

[0021] In actual use, the operator starts the vibrator 2, which drives the vibrating frame 4 to vibrate on the support frame 1 via the vibrating components. The vibrating frame 4 drives the screen 5 to vibrate, feeding plastic granules into the screen 5. Smaller plastic granules pass through the screen body 52 and fall into the bottom collection tray 3 for collection and discharge into the recycling device. Larger plastic granules remain on the top of the screen body 52 and are eventually collected in the top collection tray 413 and discharged into the recycling device. When plastic granules adhere to the bottom of the screen body 52 or clog the mesh of the screen body 52, the motor 46 can be started to drive the threaded rod 47 to rotate. The threaded rod 47 and the movable plate 48 make a threaded movement, driving the bristles 49 to clean the plastic granules accumulated and clogged on the screen body 52, reducing manpower waste and improving work efficiency. When disassembling and repairing the screen 5, the operator rotates the rotating wheel 562 to drive the threaded rod 563 to rotate and make a threaded movement with the movable tube 565. The movable tube 565 drives the fixed block 566 to detach from the fixed block. Inside the fixed groove 412, the screen 5 enters the movable groove 410. Then, the motor 46 is started, causing the movable plate 48 to move the screen 5 to one end of the vibrating frame 4. The insert plate 53 disengages from the inner wall of the slot 43, allowing the operator to remove the screen 5 for maintenance. After maintenance, the screen body 52 is placed at the top end of the fixed frame 41, and the fixing piece 56 is inserted into the movable groove 410, with the insert plate 53 at the bottom of the guide plate 44. Then, the motor 46 is started, causing the movable plate 48 to move the screen 5 until the four limit blocks 55 are respectively inserted into the four limit slots 45, and the insert plate 53 is fully inserted into the slot 43. Finally, the rotating part 562 is rotated, causing the threaded rod 563 to make threaded movement with the movable tube 565. The movable tube 565 slides in the inner wall of the receiving tube 561, causing the fixing block 566 to disengage from the movable groove 410 and insert into the inner wall of the fixed groove 412 for fixation. The tension spring 564 prevents loosening, achieving quick installation of the screen 5 and facilitating operation by the staff.
