The second motor drives the disc to rotate, driving the rotating rod and the second hinged rod to make the screening plate reciprocate left and right in the box to screen the cut particles and separate the particles that do not meet the size requirements. The setting of the screening plate can ensure that only particles that meet the size standards enter the subsequent process, improve product consistency and quality, and meet the precision requirements of insulating plastic particles in different application scenarios.
