[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The limit members 32 are threadedly connected to the bidirectional screw rod 31 through the threaded hole at the upper end. The lower end of the limit member 32 is in contact with the base 1. Before cutting the medical film, the film is placed between the advancing roller 22 and the pressing roller 12 from one end of the base 1. Then the advancing motor 21 drives the advancing roller 22 to rotate, so that the film above the advancing roller 22 moves toward the other end of the base 1. At the same time, the motor 3 is adjusted to drive the bidirectional screw rod 31 to rotate, so as to adjust the distance between the limit members 32 at both ends of the bidirectional screw rod 31 according to the width of the film. The two limit members 32 are against the internal film, so that the film keeps moving horizontally;

[0023] Combined with attachment Figure 1 、 2 3. A U-shaped connecting frame 4 is provided on the other side of the upper end of the base 1. A cylinder 1 41 is provided at the lower end of the connecting frame 4. Cylinder 1 41 is fixedly connected to a pressure plate 42 via a telescopic rod. A non-slip pad is provided at the lower end of the pressure plate 42. A cutting mechanism 5 is provided on the connecting frame 4 on one side of the cylinder 1 41.

Cylinder 2 51 is fixedly connected to the knife holder via a telescopic rod. The cutting blade 52 is provided at the lower end of the knife holder. A cutting plate 13 is provided on the base 1 at the lower end of the connecting frame 4. When cutting, cylinder 1 41 first drives the pressure plate 42 downward, causing the non-slip pad to squeeze and fix the film below, effectively preventing wrinkles and deformation of the film during the cutting process. Then, cylinder 2 51 drives the knife holder downward, and the cutting blade 52 cuts the film on the cutting plate 13.

[0024] The working principle of this application is:

[0025] Before cutting the medical film, the film is placed between the pushing roller 22 and the pressure roller 12 from one end of the base 1, and then the pushing motor 21 drives the pushing roller 22 to rotate, so that the film above the pushing roller 22 moves to the other end of the base 1, and at the same time, the adjustment motor 3 drives the bidirectional screw rod 31 to rotate, so as to adjust the spacing between the limit members 32 at both ends of the bidirectional screw rod 31 according to the width of the film. The two limit members 32 are against the internal film, so that the film maintains horizontal movement; when cutting, the cylinder 1 41 first drives the pressure plate 42 to descend, so that the anti-slip pad squeezes and fixes the film below, effectively avoiding wrinkles and deformation of the film during the cutting process, and then the cylinder 2 51 drives the knife holder to descend, and the cutting blade 52 shears the film on the cutting plate 13. This patent sets an adjustment motor 3 to control the rotation of the bidirectional screw rod 31, so that the limiter 32 limits the internal medical film, so that the film keeps moving horizontally, and the medical film below is fixed by the cylinder 141 in conjunction with the fixed plate 11, and the medical film is flattened, avoiding the medical film being easily deformed and shifted by the force of the cutter during the shearing process, thereby affecting the shearing effect.

In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
