further, a support 4 is arranged on the mounting frame 1, a guide rail 25 is arranged on the support 4, the guide rail 25 is perpendicular to the conveyed raw materials, a cutting piece 26 is arranged on the guide rail 25 in a sliding mode, and a power mechanism is arranged on the cutting piece 26 and used for driving the cutting piece 26 to slide on the guide rail 25; the support 4 is provided with a driving mechanism 22 positioned at two sides of the guide rail 25, the moving end of the driving mechanism 22 is provided with a pressing plate 24, and the support 4 is provided with a guide roller 23 for guiding the conveyed raw materials; the driving mechanism 22 works to make the pressing plate 24 close to the support 4 for pressing the raw material on the support 4 (so that the raw material can not shift in the process of cutting the raw material); then the power mechanism works to move the cutting piece 26 on the guide rail 25 to cut off the raw material for replacing the raw material;
furthermore, a mounting groove 19 is formed at the connecting part of the mounting ring 11 and the rack 20, one end of the rack 20 is inserted into the inner cavity of the mounting groove 19 in a sliding manner, and an elastic element is arranged between the mounting groove 19 and the rack 20 and used for supporting the rack 20; when the arc-shaped lug 21 and the rack 20 are mutually extruded in the process of resetting the driving ring 12 and enabling the arc-shaped lug 21 to cross the rack 20, the rack 20 can move into the inner cavity of the placing groove 19, and the rack 20 cannot influence the resetting of the driving ring 12;
further, a plurality of sensors 8 are arranged on the mounting rack 1, and the sensors 8 comprise a sensor for detecting whether the raw material is broken or not, a sensor for detecting whether the raw material is short of the raw material and a sensor for detecting the tightness of the raw material;
in summary, the working process of the film rolling mechanism is as follows: pulling the raw material on the material roller 2 to rotate the material roller 2, releasing part of the raw material, and enabling the raw material to pass through the guide roller 3 and the pull roller 5; when feeding, the driving piece 9 is electrified to work to drive the pull roll 5 to move downwards, and the raw material is pulled to move downwards (the raw material passes below the pull roll 5), and the raw material is pulled, so that the material roller 2 is driven to rotate to release the raw material on the material roller 2; then the driving piece 9 moves upwards to reset with the pull roll 5 (the released raw material does not contact with the pull roll 5 along with resetting and is in a loose state), the released raw material is transmitted to the next processing area, so that the raw material is tightly attached to the lower part of the pull roll 5, and then the pull roll 5 moves downwards again to perform feeding;
