[0003] During the film laminating process, since the cardboard exists independently, it is necessary to cut the film. The current cutting structure often drives a horizontally arranged cutting knife to move through a cylinder to perform the cutting operation on the film. However, since the film is not clamped and fixed during the cutting process and has a certain toughness itself, the problem of incomplete cutting is likely to occur during cutting, affecting the quality of the product. Summary of the Utility Model

The outer surfaces of both cross frames are fixedly connected with mounting collar rings. Vertically fixed electric telescopic rods are fixedly connected inside both mounting collar rings. The tops of both electric telescopic rods are horizontally fixedly connected with connecting seats. A device frame with a hollow interior and an open bottom is horizontally fixedly connected between both connecting seats. Slide grooves are respectively arranged along the length direction on the inner surfaces of both sides of the device frame. Transversely sliding blocks are respectively connected inside both slide grooves. A sliding bar is horizontally fixedly connected between multiple sliding blocks on both sides. A cutting blade is fixedly connected to the bottom of the sliding bar, and the bottom of the cutting blade extends downward through the open bottom of the device frame.

[0006] Preferably, a rack is fixedly connected to the upper surface of the sliding bar along the length direction thereof. Half gears are respectively rotatably connected horizontally on both sides of the upper part of the inner cavity of the device frame, and the two half gears are alternately engaged with the rack.

[0007] Preferably, servo motors are respectively horizontally fixedly connected to both sides of the outer surface of the device frame. The output shafts of both servo motors rotatably penetrate through the device frame and are respectively fixedly connected to one side surface of the two half gears.

[0017] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Please refer to Figures 1-3, the utility model provides a film cutting structure for cardboard film covering processing, which includes two horizontally arranged cross frames 1. The outer surfaces of the two cross frames 1 are fixedly connected with mounting collar rings 2. Vertically fixedly connected inside the two mounting collar rings 2 are electric control telescopic rods 3. The tops of the two electric control telescopic rods 3 are horizontally fixedly connected with connecting seats 4. Horizontally fixedly connected between the two connecting seats 4 is a device frame 5 with a hollow interior and an open bottom. The inner surfaces on both sides of the device frame 5 are provided with sliding grooves 6 along its length direction. Horizontally slidably connected inside the two sliding grooves 6 are sliding blocks 7. Horizontally fixedly connected between the multiple sliding blocks 7 on both sides is a sliding bar 8. The bottom end of the sliding bar 8 is fixedly connected with a slitting blade 9. The bottom end of the slitting blade 9 extends downward through the open bottom of the device frame 5.

[0019] The upper surface of the sliding bar 8 is fixedly connected with a rack 10 along its length direction. Horizontally rotatably connected on both sides in the upper part of the inner cavity of the device frame 5 are semi-gears 11. The two semi-gears 11 are alternately engaged with the rack 10.

[0020] In this embodiment, the device is provided with a device frame 5 with an open bottom. Horizontally slidably connected inside it is a sliding bar 8. The bottom end of the sliding bar 8 is fixedly connected with a slitting blade 9. At the same time, the top end of the sliding bar 8 is fixedly connected with a rack 10. Above the rack 10 are provided two semi-gears 11. The two semi-gears 11 are alternately engaged with the rack 10, and the rotation directions of the two semi-gears 11 are opposite, causing the rack 10 to perform repeated horizontal movements, thereby synchronously driving the sliding bar 8 and the slitting blade 9 to perform the same horizontal repeated movements. When the slitting blade 9 descends to slit the film, the film can be completely cut, ensuring the slitting effect.

[0021] Furthermore, horizontally fixedly connected to both sides of the outer surface of the device frame 5 are servo motors 13. The output shafts of the two servo motors 13 can rotatably penetrate the device frame 5 and are respectively fixedly connected to one side surface of the two semi-gears 11.

[0022] In this embodiment, the output shafts of the two servo motors 13 rotate in opposite directions, respectively driving the two semi-gears 11 to rotate, so as to realize the horizontal reciprocating movement of the slitting blade 9.

[0023] Furthermore, fixedly connected between the outer surfaces of the two connecting seats 4 and the device frame 5 are reinforcing ribs 12.

[0024] In this embodiment, the reinforcing ribs 12 play an effect of strengthening the connection, ensuring the stability of the connection between the device frame 5 and the connecting seats 4.

[0025] Furthermore, the length of the slitting blade 9 is adapted to the length of the sliding bar 8.

[0026] In this embodiment, the length of the sliding bar 8 is slightly less than the length of the device frame 5, and the length of the slitting blade 9 is adapted to the length of the sliding bar 8.

[0027] Furthermore, the bottom end of the slitting blade 9 is serrated.

[0028] In this embodiment, the serrated slitting blade 9 makes it easier to cut the film during its lateral movement.

[0029] The working principle and usage process of the present utility model: After the present utility model is installed, the device is provided with a device frame 5 with an open bottom end, inside which a sliding bar 8 is slidably connected horizontally. The bottom end of the sliding bar 8 is fixedly connected with a slitting blade 9. At the same time, the top end of the sliding bar 8 is fixedly connected with a rack 10. Above the rack 10, there are two half gears 11. The two half gears 11 alternately engage with the rack 10, and the rotation directions of the two half gears 11 are opposite, causing the rack 10 to perform repeated lateral movements, thereby synchronously driving the sliding bar 8 and the slitting blade 9 to perform the same repeated lateral movements. When the slitting blade 9 descends to slit the film, the film can be completely cut, ensuring the slitting effect.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
