At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, firstly, the plastic woven bag is put into the machine body 3 through the feed port on the top of the machine body 3, and then the driving motor 622 is started to drive the driving rod 623 and the eccentric block 624 to rotate, and the rotation of the driving rod 623 drives the driving wheel 71 to rotate, and the rotation of the driving wheel 71 drives the transmission wheel 73, the transmission rod 72 and the control bevel gear 625 to rotate synchronously, and the eccentric block 624 installed on the surface of the transmission rod 72 rotates synchronously, and the rotation of the eccentric block 624 makes the connecting plate 616, the connecting rod 615 and the sub-screen frame 611 slide to the left synchronously, and the connecting rod 615 slides inside the cross plate 612, thereby compressing the reset spring 617, and the eccentric block 624 cooperates with the elasticity of the reset spring 617 to make the sub-screen frame 611 slide back and forth left and right, and at the same time, the rotation of the control bevel gear 625 drives the rotating bevel gear 53 and the front rotating gear 52, the support rod and the crushing roller 51 to rotate synchronously, The rotation of the front rotating gear 52 drives the rear rotating gear 52, the support rod and the crushing roller 51 to rotate synchronously in the opposite direction, and the plastic woven bag is crushed by two sets of crushing rollers 51.
