[0022] In this embodiment: The composite film is conveyed into the cutting frame 1 (a frame for winding and unwinding the composite film is arranged on one side of the cutting frame 1, and a conveyor belt is arranged on the other side. The conveyor belt is used to convey the cut composite film. The frame for winding and unwinding the composite film and the conveyor belt are not shown in the figure); The motor 17 is started, the worm 15 and the turbine 14 are engaged, the turbine 14 rotates, the upper shaft 8 drives the upper gear 10 to rotate and engage with the lower gear 11, and when the upper gear 10 and the lower gear 11 rotate, they drive the upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13 to rotate. The upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13 are not in the same direction. The upper semi-circular meshing teeth 12 first engage with the meshing rack 18 on the driving bar 4, so that the meshing rack 18 drives the driving bar 4 and the cutting knife 2 to move downward synchronously to cut the composite film. After cutting, when the lower semi-circular meshing teeth 13 rotate in the reverse direction, they engage with the meshing rack 18 on the driving bar 4, so that the meshing rack 18 drives the driving bar 4 and the cutting knife 2 to move upward synchronously. By repeating this cycle, the composite film can be continuously and automatically cut, and the cutting surface is uniform, and it is not easy to tear the composite film.

[0023] As a technical optimization scheme of the present utility model, the upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13 are not in the same orientation.

[0024] In this embodiment: Through the upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13, the driving bar 4 can be alternately driven to move up and down.

[0025] As a technical optimization scheme of the present utility model, both the sliding bar 5 and the sliding groove 6 are in a dovetail structure.

[0033] Working principle: First, the composite film packaging the galvanized forceps is conveyed into the cutting frame 1 through a conveyor belt; the motor 17 is started, the worm 15 and the turbine 14 are engaged, the turbine 14 rotates, causing the upper shaft 8 to drive the upper gear 10 to rotate and engage with the lower gear 11. When the upper gear 10 and the lower gear 11 rotate, they synchronously drive the upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13 to rotate. The upper semi-circular meshing teeth 12 and the lower semi-circular meshing teeth 13 are not in the same direction. The upper semi-circular meshing teeth 12 first engage with the meshing rack 18 on the driving bar 4, causing the meshing rack 18 to drive the driving bar 4 and the cutting knife 2 to move downward synchronously to cut the composite film. After cutting, when the lower semi-circular meshing teeth 13 rotate in the reverse direction, they engage with the meshing rack 18 on the driving bar 4, causing the meshing rack 18 to drive the driving bar 4 and the cutting knife 2 to move upward synchronously. By repeating this process, continuous automatic cutting operation can be performed on the composite film, and the cutting surface is uniform, and it is not easy to cause the composite film to tear.
