A reducer 9 and a first motor 10 are fixedly connected to the upper surface of the base plate 1. The first motor 10 is fixedly connected to the upper surface of the base plate 1. A drive rod 11 is fixedly connected to the output end of the reducer 9. The drive rod 11 is rotatably connected to the inner wall of the fixed frame 8. A housing 17 is fixedly connected to the upper end of the drive rod 11. A second motor 15 is fixedly connected to the upper surface of the housing 17. A connecting rod 13 is rotatably connected to the inner wall of the housing 17. A vibrating motor 18 is fixedly connected to one end of the connecting rod 13. A vibrating screen 19 is fixedly connected to the output end of the vibrating motor 18. A particle collection frame 2 is provided on the outside of the base plate 1. A first bevel gear 14 is rotatably connected to the inner walls of both sides of the outer shell 17. A second bevel gear 16 is rotatably connected to the inner wall of the upper part of the outer shell 17. The first bevel gear 14 and the second bevel gear 16 mesh. The first bevel gear 14 is fixedly connected to one end of the connecting rod 13. The second bevel gear 16 is fixedly connected to the lower output end of the second motor 15. The output end of the first motor 10... A drive rod 11 is rotatably connected to the inner wall of the fixed frame 8, a support rod 12 is fixedly connected to the outer wall of the drive rod 11, a connecting rod 13 is rotatably connected to the inner wall of the support rod 12, a support foot 3 is fixedly connected to the upper surface of the base plate 1, a bearing platform 4 is fixedly connected to the upper surface of the support foot 3, a movable limiting plate 5 is hinged to the inner wall of the bearing platform 4, and the movable limiting plate 5 is detachably connected to the bearing platform 4 by a buckle, a collection box 6 is slidably connected to the inner wall of the bearing platform 4, and a handle 7 is rotatably connected to the collection box. The outer wall of the collection box 6, the vibrating screen 19, includes a mesh bottom surface and a solid edge. The mesh bottom surface is fixedly connected to the inner wall of the solid edge. In this device, a handle 7 is provided to facilitate the movement of the collection box 6; support feet 3 are provided to increase the height of the supporting platform 4, so that the collection box 6 can easily fit against the lower surface of the vibrating screen 19, effectively preventing material spillage. The supporting platform 4 and the collection box 6 slide against each other through a slide rail groove. The support rod 12 and the connecting rod 13, and the fixed frame 8 and the drive rod 11, all rotate relative to each other through bearings.

[0022] The bottom surface of the vibrating screen 19 is mesh-like and made of copper wire. Copper wire not only has good electrical and thermal conductivity, but also good flexibility and corrosion resistance.

[0023] In addition, the structure has four workstations, which can operate multiple workstations simultaneously or operate one workstation at a time, which greatly facilitates the replacement of the vibrating screen 19.

[0024] Working principle: During use, the feeder continuously feeds polymer plastic granules into the inner wall of the vibrating screen 19, at which time the vibration motor 18 is started. The vibration motor 18 drives the vibrating screen 19 to vibrate, thereby screening the polymer plastic granules. The screened polymer plastic granules fall into the collection box 6, completing the screening of polymer plastic granules.

[0025] When cleaning is required, the drive rod 11 rotates under the rotation of the first motor 10 and the transmission action of the reducer 9, which in turn drives the support rod 12, the outer shell 17, the connecting rod 13, the vibrating motor 18, and the vibrating screen 19 to rotate horizontally. At this time, the second motor 15 drives the second bevel gear 16 to rotate on the inner wall of the outer shell 17, and then the first bevel gear 14 and the connecting rod 13 rotate, thereby causing the vibrating screen 19 to flip. Then, the vibrating motor 18 drives the vibrating screen 19 to vibrate, cleaning the polymer plastic particles inside the vibrating screen 19. These polymer plastic particles are collected through the particle collection frame 2.
