To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0036] When implementing, follow these steps:

[0037] 1) First, start the output shaft of the reduction motor 405 to rotate, and use the transmission of the belt ring to make the two pulleys 404 rotate synchronously, so as to convey the film material into the gap between the pressure roller 402 and the conveying roller 403;

[0038] 2) Then, the film material is moved by the rotating conveying roller 403, and the rotation of the left conveying roller 403 drives the driving wheel 410 located in front of the front limiting plate 401;

At the same time, the design of the pulley 404 and the belt loop allows the two conveying rollers 403 to rotate synchronously, further improving the power of the film material movement and reducing the resistance during movement. The pressure roller 402 located above the two conveying rollers 403 can ensure the pressing of the film material, thereby preventing the problem of film material deviation during the cutting process, and further facilitating the use of the operator.

[0041] Moreover, by utilizing the design of the conveying wheel 408 and the connecting rod 407, a pressing type conveying structure is formed inside the cutting seat 2, which can not only drive the film material to continue to move toward the cutting direction of the cutting seat 2, but also achieve a certain pressing effect on the film material, thereby ensuring the stability of feeding and further facilitating the use of the staff. At the same time, by utilizing the design of the driven wheel 409 and the driving wheel 410, the connecting rod 407 is affected by the rotation of the output shaft of the reduction motor 405 with the cooperation of the quick-change transmission belt, thereby reducing the power loss in the fixed-length film cutting operation, and the quick-change transmission belt can replace quick-change transmission belts of different sizes according to the distance between the cutting seat 2 and the limiting plate 401 in the batch film cutting operation for transmission, thereby avoiding interference with the distance adjustment between the cutting seat 2 and the limiting plate 401, further facilitating the operation of the staff, and solving the problem of reduced film forward efficiency and large forward resistance in the comparative text, which affects the stability and efficiency of the cutting operation.
