[0025] In an optional embodiment, a positioning vertical rod 8 is fixedly connected to the lower surface of the other connecting block 6 , and a positioning vertical groove 9 matching the positioning vertical rod 8 is formed inside the film roll fixing rod 3 .

[0026] In an optional embodiment, the motor 11 is connected to an external power source.

[0027] In an optional embodiment, the vertical plate 2 is fixedly connected to the upper surface of the packaging machine body 1, the film roll cylinder fixing rod 3 is fixedly connected to the outer surface of the vertical plate 2, the outer surface of the film roll cylinder fixing rod 3 is rotatably sleeved with a film roll 4, and the outer surface of the film roll cylinder 4 is coiled and connected with a card protection film 5.

[0028] In this embodiment, the model of the motor 11 is YSK100-20-4P.

[0029] Working principle: The film roll of the traditional card film wrapping packaging machine needs to guide and limit the film when it is released. However, as the film is released, the thickness of the film on the film roll will decrease. The traditional device for guiding and limiting the film is generally fixedly connected. When the thickness of the film decreases by a certain distance, the limiting effect of the guide and limiting device is greatly reduced. In this embodiment, after the motor 11 is started, the output end of the motor 11 drives the first cam plate 12 to rotate. When the first protrusion on the first cam plate 12 rotates to contact with the first gear 13, it drives the first gear 13 to rotate. The first gear 13 drives the second cam plate 14 to rotate synchronously. When the second protrusion on the second cam plate 14 rotates to contact with the second gear 15, it drives the second gear 15 to rotate. The second gear 15 passes The meshing connection with the rectangular rack 17 drives the rectangular rack 17 to move up and down, and the direction of the up and down movement is determined by the rotation direction of the motor 11. When the rectangular rack 17 moves downward, it drives the connecting cross bar 10, the connecting block 6 and the limiting guide roller 7 to move downward. As the coiling thickness of the card protection film 5 on the film winding drum 4 continues to decrease, the limiting guide roller 7 also continues to decrease, and the guiding and limiting effect on the card protection film 5 can be maintained all the time; during the up and down movement of the limiting guide roller 7, the positioning vertical rod 8 moves in the positioning vertical groove 9, which can provide a positioning effect for the limiting guide roller 7; through the design of the first cam plate 12, the first gear 13, the second cam plate 14 and the second gear 15, the up and down movement frequency of the rectangular rack 17 can be greatly reduced, thereby matching the film discharge speed of the card protection film 5;

[0030] In summary, as the coil thickness of the card protection film 5 on the film winding drum 4 continues to decrease, the device can make the limiting guide roller 7 continue to descend, so as to always maintain the guiding and limiting effect on the card protection film 5; through the design of the first cam plate 12, the first gear 13, the second cam plate 14 and the second gear 15, the up and down movement frequency of the rectangular rack 17 can be greatly reduced, so as to match the film output speed of the card protection film 5; through the design of the limiting guide roller 7 and the positioning vertical rod 8, the limiting guide roller 7 can be provided with a positioning effect.
