[0009] Preferably, a sealing plate is fixed on the push rod at a position corresponding to the chute, and the sealing plate slides on the surface of the chute to seal the chute, thereby preventing the PE material from being discharged from the chute.

[0010] Preferably, baffles are fixed in the crushing kettle on both sides above the driven shaft to block the PE waste from passing between the two knife rollers.

[0011] Preferably, a vibration motor is fixed on the crushing kettle below the support plate, and a cam is fixed on the output end of the vibration motor. The vibration motor drives the cam to rotate, and the cam collides with the support plate to ensure that the PE material slides on the guide plate and avoids clogging the through hole.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The device can realize multiple crushing of PE waste, and the crushed PE material is discharged and collected through the through hole after the particle size reaches the requirement. BRIEF DESCRIPTION OF THE DRAWINGS
