thirdly, when the two ends of the thin film are cut, the movable motor (3261) works to drive the first movable toothed plate (3263) and the second movable toothed plate (3264) to move at the bottom of the mounting rack (321) through the first movable rod (3265) and the second movable rod (3266), the first movable rod (3265) moves to drive the first mounting plate (322) to move, the second movable rod (3266) moves to drive the second mounting plate (323) to move, the first mounting plate (322) and the second mounting plate (323) move to drive the first slitting blade (324) and the second slitting blade (325) to move, the positions of the first slitting blade (324) and the second slitting blade (325) are adjusted to suitable cutting positions, and the thin film moved on the conveying belt (21) is cut;

fourthly, after the two ends of the film are cut, the waste materials on the two sides continuously move forwards, when the waste materials move into the crushing box (71), the crushing motor (72) works to drive the crushing blade (73) to rotate on the crushing box (71), the crushing blade (73) crushes the waste materials, the crushed waste materials are moved into the material collecting cover (74), and the waste materials are collected through the material collecting cover (74);

fifthly, when the length of the film is cut, a driving motor (41) works to drive a first driving rod (43) to rotate on a conveying frame (2), the first driving rod (43) rotates to drive a driving wheel (42) to rotate, the driving wheel (42) rotates to drive a positioning rod (492) to rotate so as to drive a connecting plate (45) to rotate on a second driving rod (44), the connecting plate (45) rotates to drive a connecting rod (46) to rotate so as to drive a connecting frame (47) to move up and down on the conveying frame (2), the connecting frame (47) moves up and down to drive a cutting seat (48) to move up and down through two cutting rods (491), the cutting seat (48) moves up and down to drive a cutting blade (49) to move down to match the conveying frame (2) to cut the film, and the film is cut into films with the same length;

sixthly, after the film is cut, the film moves between an upper flattening roller (52) and a lower flattening roller (53), a flattening motor (54) works to drive a threaded rod (55) to rotate on a flattening frame (51) through a connecting belt, the threaded rod (55) rotates to drive two rotating discs (56) to rotate, the two rotating discs (56) rotate to respectively drive the upper flattening roller (52) to rotate on two sliding blocks, the lower flattening roller (53) is driven to rotate on the two flattening frames (51), and the upper flattening roller (52) and the lower flattening roller (53) rotate to flatten the film;

seventhly, after the film is flattened, the position of the blanking collecting plate (65) is located below the flattening frame (51), the film is moved to the blanking collecting plate (65) after being flattened, the third moving rod (63) is driven to work by the electric cylinder (62) at the moment, the third moving rod (63) moves to drive the two rotating frames (64) to rotate on the two positioning blocks (69), so that the two positioning blocks (69) are driven to rotate on the two sliding rods (66), the two rotating frames (64) rotate to drive the blanking collecting plate (65) to rotate, the position of the blanking collecting plate (65) is moved forward, the blanking collecting plate (65) rotates along with the rotation of the two rotating frames (64) to overturn the position of the blanking collecting plate (65), and the processed film is moved to a storage position.
