[0022] like Figure 1 and Figure 4 As shown, the connecting mechanism 11 includes a vibrating screen 111, a limiting frame 112, a first supporting frame 113, a screw sleeve 114, a limiting screw 115, a first sliding frame 116 and a second telescopic spring 117. The upper part of the vibrating plate 9 is slidably connected to the vibrating screen 111, and the limiting frames 112 are connected to the front and rear sides of the vibrating screen 111. The first supporting frames 113 are connected to the front and rear sides of the vibrating plate 9. The first supporting frames 113 are slidably connected to the adjacent limiting frames 112, and the screw sleeves 114 are connected to the sides of the first supporting frames 113 that are away from each other. 14. The screw sleeve 114 is threadedly connected with the limit screw 115, and the limit screw 115 is provided with a knob to facilitate the rotation of the limit screw 115. The front and rear sides of the vibration screen 111 are connected with multiple first sliding frames 116, and the first sliding frames 116 are slidably connected to the adjacent first supporting frames 113. The first sliding frames 116 are provided with the second telescopic springs 117 between the adjacent first supporting frames 113, and the second telescopic springs 117 can be disassembled.

[0023] like Figure 1 , Figure 5 and Figure 6As shown, the adjusting mechanism 12 includes a second sliding frame 121, a third telescopic spring 122, a second supporting frame 123, a limiting rod 124 and a fourth telescopic spring 125. The second sliding frame 121 is slidably connected to the top of the guide rail 8. Limiting holes are provided on the front and rear sides of the second sliding frame 121. The third telescopic spring 122 is connected between the top of the second sliding frame 121 and the guide rail 8. A plurality of second supporting frames 123 are connected to the front and rear sides of the guide rail 8. The limiting rod 124 is slidably connected to the second supporting frame 123. The fourth telescopic spring 125 is connected between the limiting rod 124 and the adjacent second supporting frame 123.

The connecting frame 6 pulls the pressing frame 7 up and down by rotating, so that the pressing frame 7 reciprocates up and down in the guide rail 8. When the pressing frame 7 moves upward, it lifts the guide rail 8. The guide rail 8 is forced to lift the vibration plate 9 upward, so that the vibration plate 9 moves upward and stretches the first telescopic spring 10. When the first telescopic spring 10 rebounds, it can pull the vibration plate 9 downward. This reciprocating motion makes the vibration plate 9 vibrate. When the vibration amplitude of the vibration plate 9 needs to be adjusted, the second sliding frame 121 is slid up and down and fixed by the limit rod 124 of the corresponding height, which can increase or decrease the stroke of the pressing frame 7 pressing the guide rail 8, thereby controlling the vibration amplitude of the vibration plate 9. According to the screening requirements of different plastic particles, the vibration amplitude of the vibration plate 9 is controlled to improve the adaptability of the screening operation.
