Through the action of a screening frame, a screening disc, a vibration motor, a vibration spring and a crushing device, the material size can be screened, thereby achieving the purpose of facilitating crushing and improving work efficiency of the plastic crusher. The material located on the upper end surface of the screening disc is crushed by a crushing block.

[0004] It has the following defects:

[0005] When the material on the upper end surface of the screening plate is crushed by the crushing block, it may not be possible to crush all the material into standard plastic particles in one time. At this time, the crushing block needs to be squeezed and crushed multiple times to crush the material into the standard plastic particle size. If the crushing block continues to put the material into the screening frame while squeezing and crushing the material, the material will fall between the crushing block and the inner wall of the screening frame. The material falling between the crushing block and the inner wall of the screening frame cannot be crushed by the crushing block.
