[0046] When in use, the operator drags the two baffle lugs 224 to slide in the baffle limiting groove 225, the two baffle lugs 224 drive the corresponding cylindrical dust suction port baffles 223 to slide towards each other inside the dust removal shaft 221, the two cylindrical dust suction port baffles 223 block a part of the dust suction port 222, thereby adjusting the effective dust suction part of the dust suction port 222 to the width of the plastic film, so that the dust removal effect of the dust removal shaft 221 is better; then the discharging mechanism 3 is started, the plastic film passes above the static electricity eliminating rod 21, the static electricity eliminating rod 21 performs the static electricity eliminating treatment on the plastic film, the plastic film has no adsorption force on the adsorbed dust and debris after eliminating static electricity, then the plastic film passes through the film rotating shaft 9, the inner side of the plastic film to be folded is attached to the dust removal shaft 221, the dust suction port 222 provided on the dust removal shaft 221 generates suction under the driving of the dust suction fan 23, the dust and debris carried by the inner side of the plastic film to be folded are sucked into the dust suction port 222, and then are discharged through the dust suction pipe 24 and the dust suction fan 23.

[0047] The dust removal shaft 221 and the dust suction fan 23 can cooperate to adsorb the dust and attachments on the inner side of the plastic film before folding, so that the dust and attachments are prevented from being folded into the inner side of the plastic film and affecting the quality of the finished product.

[0050] The rotation shaft limiting and fixing assembly comprises a buckle 43 and a buckle shaft 44, an avoiding opening I is formed on the right side surface of the folding roller support I 75, the avoiding opening I penetrates through the front and back sides of the folding roller support I 75, the front end of the folding roller I 71 is arranged in the avoiding opening I to limit the sliding connection, the buckle shaft 44 is fixedly connected with the top of the right side surface of the folding roller support I 75, the top of the buckle 43 is rotationally connected with the buckle shaft 44, a clamping groove is formed on the inner bottom wall of the avoiding opening I, and the bottom end of the buckle 43 can be rotationally inserted into the clamping groove.

[0051] In use, the operator rotates the buckle 43 when first feeding, so that the buckle 43 no longer limits the front end of the folding roller I 71, then the operator moves the sliding block 41 to slide in the sliding block limiting groove 45, so that the distance between the folding roller I 71 and the folding roller II 73 is increased, then the operator passes the plastic film between the folding roller I 71 and the folding roller II 73, at this time, the plastic film passes between the roller I 72 and the roller II 74 after being folded, then the front end of the folding roller I 71 is reset, the buckle 43 is pushed back to the clamping groove to limit the folding roller I 71 again, so that the front end of the folding roller I 71 cannot move left and right, at the same time, the sliding block 41 is moved to reset, then the screw is screwed into the screw hole through the slot 42 to fix the sliding block 41.

[0052] The experiment can solve the problem that the operator is difficult to feed due to the too close distance between the folding roller I 71 and the folding roller II 73 under the triangular plate 5 when first feeding through the folding roller opening mechanism 4.
