The position of the pressure strip plate 43 is arranged corresponding to the center position of the crusher 3, and the horizontal height of the pressure strip plate 43 is higher than the horizontal height of the crusher 3. The belt pressure plate 42 is driven downward by the telescopic motor 41 so that the pressure strip plate 43 moves downward synchronously, that is, the pressure strip plate 43 presses down the waste plastic located on the crusher 3.

[0030] like Figure 3 and Figure 4 As shown, the two sides of the pressure plate 42 are respectively hinged with a dial plate 44, and the two dial plates 44 are symmetrically arranged. The horizontal height of the two dial plates 44 is higher than the horizontal height of the pressure plate 42. When the pressure plate 42 moves downward, the dial plates 44 on both sides move downward synchronously to approach the waste plastics on both sides.
