The raw material roller I and the raw material roller II are exchanged, so that the position of a running path of the raw material film can be kept unchanged when the raw material film is spliced, and the position of a cutting-off knife can be well set. The positions of the first raw material roller and the second raw material roller are exchanged by the aid of the transposition frame 9 after splicing, so that the splicing positions of the first raw material film and the second raw material film are unchanged during next splicing, the raw material film below is always in an about-to-use state, the raw material film above is always in a running starting state, and the cutting position of the cutting-off knife is unchanged.

As shown in fig. 3, the cutting blade 5 includes an upper cutting blade 51 and a lower cutting blade 52, the bodies of the upper cutting blade 51 and the lower cutting blade 52 are both strip-shaped, one edge of the body is a cutting edge, the left end of the upper cutting blade is fixedly connected with a first guide plate 511 downwards, the first guide plate 511 is provided with a first guide surface 515, the first guide plate 511 is perpendicular to the upper cutting edge 512 of the upper cutting blade 51, and the first guide surface of the first guide plate 511 is perpendicular to the first raw material film 31. The upper cutting blade 51 is vertically hinged on a hinge column 56 on the wall panel 1 of the film cutting machine through a hinge hole 513, a stop flap 514 is further arranged on the upper cutting blade 51, a stop plate 55 matched with the stop flap 514 is correspondingly arranged on the wall panel 1, and the stop flap can be a stop block or other components capable of stopping the continuous rotation of the upper cutting blade. The upper cutting blade 512 is hinged to the wall panel and is rotatable about the hinge axis to be defined by the stop plate at a position perpendicular to the wall panel.

The left end of the lower cutting blade 52 is fixedly connected with a second guide plate 521 in an upward direction, the second guide plate 521 is provided with a second guide surface 523, the second guide plate 521 is perpendicular to the lower cutting blade 522, and the upper cutting blade 512 and the lower cutting blade 522 are parallel and are arranged in opposite directions. Still include cylinder 53, fixed the setting lower cutting knife support 54 on the wallboard, cylinder 53 is fixed to be set up on lower cutting knife support 54, lower cutting knife 52 is fixed to be set up on the piston rod of cylinder 53, and cylinder 53 of this embodiment is the double-stroke cylinder, has first stroke and second stroke. When the material needs to be changed, the upper cutting blade 51 is opened, the raw material film I31 is positioned below the upper cutting blade 51 and above the lower cutting blade 52, so that the cutting is more reliable, before the raw material film I31 is spliced with the raw material film II 41, the first stroke of the opening air cylinder 53 pushes the lower cutting blade 52 to enable the tail end of the guide surface I515 to be attached to the starting end of the guide surface II 523 for preparatory guidance, and when the splicing roller I61 and the splicing roller II 62 move towards each other to perform splicing operation, the second stroke of the opening air cylinder 53 pushes the lower cutting blade 52 to enable the guide plate II 521 to move along the guide plate I511, so that the lower cutting blade 522 moves towards the upper cutting blade 512 to cut the raw material film I31. Of course, as a more complicated alternative, the upper and lower cutting blades 51 and 31 may be set to move toward each other to cut the raw material film. After the raw material film is replaced, the piston rod of the air cylinder is in a retraction initial state, the upper cutting knife 51 is not in contact with the lower cutting knife 52, and the upper cutting knife 51 can rotate around the hinge column 56 to be folded close to the wall plate 1, so that the operation of the raw material film is prevented from being influenced.
