At the same time, the screening mechanism 7 can drive the screening frame 4 to move back and forth to screen impurities from the crushed plastic, thereby facilitating the subsequent cleaning of the plastic blocks;

[0038] The driving mechanism can drive the two squeezing rollers 3 to rotate relative to each other, thereby squeezing the plastic bottles to make them flatter, thereby reducing the hollowing of the plastic bottles, and thus better crushing the plastic bottles in a regular manner. The screened impurities can be collected by the collecting mechanism, and the generation of dust during the crushing process can be reduced.
