The downward movement of the cutting knife 51 will squeeze the film to make it close to the support seat 511, and when the cutting knife 51 is stuck in the inside of the knife groove 512, the cutting of the film can be completed by pressing and cutting.
[0031] Reference Figure 1 - Figure 3 The fixing assembly 5 also includes a connecting rod 52 for driving the rack 53 to move. The connecting rod 52 passes through and is slidably connected to the top of the inner wall of the bracket 3. The bottom end of the connecting rod 52 is fixedly connected to an upper clamping plate 55 for fixing the top of the film. The top of the upper clamping plate 55 is slidably connected to a slide plate 514 for driving the upper clamping plate 55 to move downward. The top of the cutting knife 51 is fixedly connected to a pressing plate 56 for squeezing the slide plate 514. The top of the upper clamping plate 55 is fixedly connected to an extrusion spring 57 for squeezing the upper clamping plate 55. When the cutting knife 51 moves downward, it will drive the pressing plate 56 to squeeze the slide plate 514 downward, and the slide plate 514 will squeeze the film. The spring 57 drives the upper clamping plate 55 to move downward. The top end of the extrusion spring 57 is fixedly connected to the bottom end of the slide plate 514. The use of the extrusion spring 57 to connect the slide plate 514 and the upper clamping plate 55 can prevent the film from being damaged due to excessive extrusion force. The top end of the upper clamping plate 55 is fixedly connected with a block 58 for protecting the extrusion spring 57. The top end of the connecting rod 52 is fixedly connected with a rack 1 53 for driving the rotating wheel 54 to rotate. The inner wall of the bracket 3 is rotatably connected with a rotating wheel 54 for connecting the rack 1 53 and the rack 2 510. The rack 1 53 and the rotating wheel 54 are meshed with each other. When the rack 1 53 moves downward, it will drive the rotating wheel 54 to rotate synchronously.
[0032] Reference Figure 1 - Figure 3 The inner wall of the bracket 3 is slidably connected with a rack 2 510 for driving the lower clamping plate 59 to move. The rack 2 510 and the rotating wheel 54 are meshed with each other. When the rotating wheel 54 rotates driven by the rack 1 53, the rotating wheel 54 will drive the rack 2 510 to move in the opposite direction to the rack 1 53.

The right end of the lower clamping plate 59 is provided with a locking assembly 6 for fixing the lower clamping plate 59. The top of the upper clamping plate 55 is fixedly connected with a reset spring 513 for driving the upper clamping plate 55 to move upward and reset. The top of the reset spring 513 is fixedly connected to the top of the inner wall of the bracket 3. When the pressing plate 56 does not press the sliding plate 514 downward, the reset spring 513 will pull the upper clamping plate 55 upward. To make it move upward and reset, the locking assembly 6 includes a locking block 61 for fixing the lower clamping plate 59, and the right end of the inner wall of the bracket 3 is provided with a locking groove 63 for accommodating the locking block 61. The locking block 61 and the locking groove 63 are adapted to each other. When the locking block 61 is inserted into the locking groove 63, the lower clamping plate 59 will be fixed and cannot move. The left end of the locking block 61 is fixedly connected with a locking spring 62 for pushing the locking block 61 outward. The left end of the locking spring 62 is fixedly connected to the inner wall of the lower clamping plate 59. When the locking block 61 is aligned with the locking groove 63, the locking spring 62 will push the locking block 61 to move outward and insert it into the locking groove 63. The right end of the locking groove 63 passes through and is slidably connected with an unlocking block 64 for facilitating the operator to push the locking block 61.
[0033] Working principle: when cutting is required, the film can be guided through the device first, and then the electric telescopic rod 4 can be started to drive the cutting knife 51 to move downward. The downward movement of the cutting knife 51 will drive the pressure plate 56 to move synchronously, and the pressure plate 56 will squeeze the slide plate 514. The slide plate 514 will drive the upper splint 55 to move downward by squeezing the squeezing spring 57. The downward movement of the upper splint 55 will drive the connecting rod 52 to move synchronously, and the connecting rod 52 will drive the rack 1 53 to move synchronously. The rack 1 53 will drive the rotating wheel 54 to rotate. The rotation of the rotating wheel 54 will drive the rack 2 510 to move upward. The upward movement of the rack 2 510 will drive the lower splint 59 to move upward. At this time, the upper splint 55 and the lower splint 59 will move toward each other until the film is fixed in the middle position between the two. At the same time, the cutting knife 51 will also squeeze the film to cut it.
[0034] When the lower clamping plate 59 rises, it will drive the locking block 61 to move upward synchronously. When the locking block 61 is aligned with the locking groove 63, the locking spring 62 will push the locking block 61 to move to the right and fit into the locking groove 63. Therefore, when the cutting knife 51 moves upward and resets, the lower clamping plate 59 and the upper clamping plate 55 will continue to squeeze the upper and lower ends of the film. This can prevent the film from falling from the cut point and causing contamination, and can facilitate the operator to guide the film to move. When the lower clamping plate 59 and the upper clamping plate 55 need to be reset, just push the unlocking block 64 to the left to drive the locking block 61 to move to the left and disengage from the locking groove 63. Then the reset spring 513 will pull the upper clamping plate 55 upward to move it upward and reset it. The upper clamping plate 55 will also drive the lower clamping plate 59 to move downward and reset it through the rack 1 53, the rotating wheel 54, and the rack 2 510.
