s3, after cutting, gradually rolling the film onto a take-up roll 4;
s4, when the size of the cut film needs to be adjusted, the position of the annular cutter 73 is adjusted through the sliding support cylinder 71, and therefore the gap between the annular cutters 73 is adjusted.
The working principle of the invention is as follows: the lithium battery film 23 is wound up on the unwinding roller 2, the film is passed around the driving roller 3 at the time of slitting, and the film is driven to move by the driving roller 3, when the film passes through between the cutting roller 5 and the backing knife roller 6, the linear speed of the annular cutter 73 is the same as the moving speed of the film, so that the annular cutter 73 gradually cuts the film, after the cutting is finished, the film is gradually wound on the winding roller 4, when the size of the cut film needs to be adjusted, the position of the annular cutter 73 is adjusted through the sliding support cylinder 71, thereby adjusting the gap between the annular cutters 73, when adjusting the position of the annular cutters 73, the locking bolts 74 are firstly unscrewed, then the supporting cylinder 71 is slid, the locking bolt 74 is tightened, and the locking bolt 74 drives the arc-shaped pressing plate 75 to move towards the cutting roller 5 so as to press the cutting roller 5, so that the supporting cylinder 71 is difficult to slide relative to the cutting roller 5; after the position of the annular cutter 73 is adjusted, the position of the annular supporting pad 9 beside the annular cutter 73 needs to be adjusted, so that the knife edge of the annular cutter 73 is located at a gap between the two annular supporting pads 9, when the position of the annular supporting roller is adjusted, the driving component drives the sliding disc 15 to move beside the annular supporting roller, so that the outer gear ring 16 is meshed with the inner gear ring 13, then the sliding disc 15 rotates, the sliding disc 15 drives the outer gear ring 16 to rotate, the outer gear ring 16 drives the inner gear ring 13 to rotate when rotating, so as to drive the arc-shaped push plate 14 to rotate, the arc-shaped push plate 14 gradually pushes the fixing plate 10 to move towards the direction far away from the inner gear ring 13 when being annular, so that the pressure of the fixing plate 10 on the annular supporting pads 9 is improved, and the annular supporting pad 9 is fixed; when the driving sliding disk 15 rotates, the driving motor 22 is started, the output end of the driving motor 22 drives the screw rod 19 to rotate, so that the sliding disk 15 is driven to move, and when the sliding disk 15 needs to be driven to rotate, the driving disk 21 is rotated, and the driving disk 21 drives the sliding disk 15 to rotate through the limiting column 20.
