The rotating disk 6012, in turn, drives the rotating plate 603 and the rotating shaft 602 to rotate via the fixed ring block 6013, the drive plate 6014, and the connecting ring block 6015. The rotating plate 603 reciprocates due to the eccentric rotation of the fixed ring block 6013. The rotation of the rotating plate 603 drives the two connecting plates 604 and 605. The connecting rods 606 reciprocate. When one connecting rod 606 moves to one side, the other connecting rod 606 moves in the opposite direction. While the two connecting rods 606 are moving, they can smoothly drive the first screening plate 607 and the second screening plate 608 to move together. The raw material particles screened by the first screening plate 607 will fall into the interior of the second screening plate 608 and be further screened by the second screening plate 608. Finally, particles that meet the size requirements will fall into the interior of the feed hopper 2 for injection molding, while larger particles will be rejected by the first screening plate 607 or the second screening plate 608. This reduces the impact of larger raw material particles on the injection molding machine body 1, thereby saving energy consumption during the use of the injection molding machine body 1.
