[0002] Injection molding waste refers to the plastic that is not completely injected into the mold during the injection molding production process. These plastics are usually caused by problems such as unqualified plastic quality, unstable production process, improper injection volume setting or unreasonable mold design. Injection molding waste is usually plastic with defects such as bubbles, shrinkage holes, black spots, etc., which cannot be directly used to produce qualified products, so it needs to be processed. However, injection molding waste is not completely worthless. Through recycling, production costs can be reduced, waste can be reduced, and environmental protection concepts can be met.

The reciprocating swinging screen can swing and screen the injection molding residues after crushing that fall thereon, so that it is convenient to screen out the particles with smaller volume, which is helpful for the subsequent utilization of the injection molding particles. The screened injection molding particles with smaller volume will fall onto the discharging plate and move to the discharging frame along the inclined surface on the discharging plate, which is convenient for the staff to collect them in a centralized manner. When it is necessary to remove the particles with larger volume, the movable door is rotated outward to open the back of the shell, so that the particles with larger volume remaining on the swinging screen can be collected, which is convenient for the continuous screening of the swinging screen and improves the practicality of the device.
