The particle collecting component includes a bottom collecting box 6 installed on the inner wall of the bottom side of the plastic particle screening box 1, and a removal hole 7 is opened on one side of the plastic particle screening box 1. One side of the bottom collecting box 6 extends to the outside of the removal hole 7. After screening by the vibrating screening plate 3, qualified ones will fall into the bottom collecting box 6 below for collection.

[0023] Specifically, both sides of the vibrating screening plate 3 are rotatably mounted with a middle rotating shaft 5, and the two middle rotating shafts 5 are rotatably mounted on the inner walls of the two sides of the plastic particle screening box 1, and a tilting movable column 8 is provided on one side of the vibrating screening plate 3. The tilting movable column 8 and the plastic particle screening box 1 are installed through a connecting component, and the connecting component includes an arc hole 9 opened on one side of the plastic particle screening box 1, and one end of the tilting movable column 8 movably passes through the arc hole 9, and the tilting movable column 8 is located at one side of the middle rotating shaft 5. A rotating seat 10 is fixedly mounted on one side of the plastic particle screening box 1, and a position positioning rod 11 is rotatably mounted on one side of the rotating seat 10. A positioning hole 12 is opened on one side of the position positioning rod 11, and one end of the tilting movable column 8 is movable. A fixing bolt 13 is installed on one side of the position positioning rod 11 through the positioning hole 12, and a bolt groove 14 is opened on one side of the plastic particle screening box 1. One end of the fixing bolt 13 is threadedly installed in the bolt groove 14. After a period of screening, larger particles will fall on the vibration screening plate 3 and need to be cleaned. At this time, the staff takes out the fixing bolt 13 and then rotates to open the position positioning rod 11. At this time, the tilting moving column 8 will not be restricted by the position. The tilting moving column 8 is lifted, moved in the arc hole 9, and rotated around the middle rotating shaft 5, driving the vibration screening plate 3 to rotate and tilt, so that the unqualified plastic particles on the vibration screening plate 3 can automatically slide to one side, thereby achieving the purpose of automatic sliding cleaning.

After screening by the vibrating screening plate 3, qualified particles will fall into the bottom collection box 6 below for collection. After a period of screening, larger particles will fall on the vibrating screening plate 3 and need to be sorted. For cleaning, the staff takes out the fixing bolt 13, and then rotates the open position positioning rod 11. At this time, the tilting movable column 8 will not be restricted by the position. The tilting movable column 8 is lifted, moved in the arc hole 9, and rotated around the middle rotating shaft 5, driving the vibrating screening plate 3 to rotate and tilt, so that the unqualified plastic particles on the vibrating screening plate 3 can automatically slide to one side, achieving the purpose of automatic sliding cleaning.
