The two ends of the two limiting rods 12 are respectively connected to the inner sides of different tool fixing plates 9, a connecting rod 14 is provided at the bottom center of the sliding block 13, and the bottom of the connecting rod 14 is connected to the top center of the second connecting plate 15. A second sliding groove 18 is opened in the horizontal direction at the bottom of the second connecting plate 15, and a sliding rod 20 is slidably connected in the second sliding groove 18, and a cutting knife 19 is provided at the bottom of the sliding rod 20.

[0022] Furthermore, a first slide groove 7 is provided at both longitudinal ends of the inner center of the first connecting plate 4 , and a slider 8 is slidably engaged with the first slide groove 7 , and the inner side surface of the slider 8 is connected to both sides of the tool top plate 10 .

[0023] Specifically, after the telescopic cylinder 6 is started, the slide block 8 will slide along the first slide groove 7, and the sliding here will limit the tool top plate 10 to a certain extent, making the movement of the cutting body more stable.

[0024] Furthermore, an inner cavity 24 is opened inside one of the tool fixing plates 9 , and a driving motor 25 is fixedly connected to the outer side of the inner cavity 24 . A rotating shaft is provided at the output end of the driving motor 25 , and the other end of the rotating shaft is connected to one end of the screw rod 11 .

[0025] Furthermore, first fixing plates 16 are provided at the top of both sides of the second connecting plate 15, and first fixing openings 17 are opened through the top and bottom centers of the first fixing plate 16. Third connecting plates 21 are provided at the bottom of both sides of the sliding rod 20, and second fixing openings 22 are opened through the top and bottom centers of the third connecting plate 21. The first fixing opening 17 and the second fixing opening 22 are connected by a pin 23.

[0026] Furthermore, a control device 3 is provided at the front center of one of the side panels 2. The utility model can control the extension and retraction of the telescopic cylinder 6 and the rotation of the driving motor 25 through the control device 3, and can also control the operation of the conveyor belt 1. How to control the extension and retraction of the telescopic cylinder 6 and the rotation of the driving motor 25 through the control device 3 is the existing technology for the operation of the conveyor belt 1, and its specific connection structure and principle will not be described in detail again.

[0027] Working principle: When in use, first place the color-changing film at the starting end of the conveyor belt 1, and then the conveyor belt 1 will work through the control device 3. The operation of the conveyor belt 1 will move the color-changing film to the cutting body. After waiting for a period of time, when the size of the color-changing film here and the end of the color-changing film reaches the requirements, first close the conveyor belt 1 through the control device 3, and then start the drive motor 25 through the controller. The rotation of the drive motor 25 will cause the rotating shaft to rotate, and the rotation of the rotating shaft will cause the screw rod 11 to rotate. The rotation of the screw rod 11 will cause the sliding block 13 to slide quickly from one side to the other side. During the sliding process, the cutting knife 19 will also slide, so that the rolled color-changing film can be cut into a suitable size.

[0028] During the cutting process, it is sometimes necessary to replace the cutting knife 19. When the cutting knife 19 needs to be replaced, the conveyor belt 1 is first closed by the control device 3. After the conveyor belt 1 is closed, the telescopic cylinder 6 is retracted again by the control device 3. After the telescopic cylinder 6 is retracted, the height between the cutting knife 19 and the surface of the conveyor belt 1 will become higher, thereby facilitating the removal of the cutting knife 19. After removal, the latch 23 is first pulled out. After the latch 23 is pulled out, the staff holds it through one of the second connecting plates 21, and then pulls the second connecting plate 21 outward. During the pulling process, the sliding bar 20 will slide out of the second sliding groove 18, thereby removing the old cutting knife 19. After removal, the staff holds the second connecting plate 21 again, aligns the sliding bar 20 with the second sliding groove 18, and then pulls it in the opposite direction, thereby sliding the new cutting knife 19 in. After it cannot slide again, it is fixed again by the latch 23.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
