Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0032] This embodiment is a film laminating device for carton processing that is easy to adjust.

[0033] As Figure 1 and Figure 3 shown, the conveyor belt 1 is fixedly installed inside the connecting plate 2. The connecting plate 2 is symmetric about the central axis of the conveyor belt 1. The lower side of the connecting plate 2 is placed on the ground. Mounting holes 3 are opened inside the connecting plate 2. The connecting plate 2 is threadedly connected to the threaded rod 4 through the mounting holes 3. The rear side of the threaded rod 4 is rotatably connected to the limiting plate 5. Connecting holes 7 are opened inside the connecting plate 2. The connecting holes 7 are symmetric about the vertical central axis of the connecting plate 2. The front side of the limiting plate 5 is fixedly connected to the limiting rod 6. The limiting rod 6 is slidably connected to the connecting holes 7. In addition, the mounting holes 3, the threaded rod 4, the limiting plate 5, the limiting rod 6, and the connecting holes 7 all correspond to the connecting plate 2 one by one. A pressing rod 8 and a heating roller 9 are arranged on the upper left side of the conveyor belt 1, and the pressing rod 8 is located on the right side of the heating roller 9.

[0034] As Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the connecting frame 10 is fixedly installed on the left side of the connecting plate 2, and the connecting frames 10 correspond to the connecting plates 2 one by one. A connecting block 11 is fixedly connected to the inner side of the connecting frame 10. The connecting blocks 11 are arranged in an array. A moving plate 12 is slidably connected inside the connecting block 11. The moving plate 12 is symmetric about the vertical central axis of the connecting block 11. A limiting block 13 is rotatably connected to the lower side of the moving plate 12. A cross bar 15 is rotatably connected inside the moving plate 12. A cross bar 15 is arranged inside the moving plate 12. One end of a side surface of the cross bar 15 is fixedly connected to a spring 16, and the other end of the spring 16 is fixedly connected to the connecting block 11. The moving plate 12, the limiting block 13, the buffer roller 14, the cross bar 15 and the spring 16 are arranged in an array. In addition, a connecting frame 17 is arranged on the upper right side of the connecting plate 2. An electric telescopic rod 18 is arranged on the lower side of the connecting frame 17. A cutting knife 19 is fixedly connected to the lower side of the electric telescopic rod 18.

[0035] It should be noted that before use, the plastic film is passed through the side surface of the buffer roller 14, bypassing all the buffer rollers 14, and then the plastic film is placed above the heating roller 9. When the cardboard box is conveyed, the plastic film is placed on the upper side of the cardboard box, and then the cardboard box and the plastic film are conveyed to the right together from under the pressing rod 8. The pressing rod 8 will soften the plastic film to facilitate the connection between the plastic film and the cardboard box. Specific Embodiment Two

[0037] This embodiment is to solve the problem that the cardboard box may shift during the conveying process.

[0038] As Figure 1 and Figure 3 shown, the lower side of the limiting plate 5 is not in close contact with the upper side of the conveyor belt 1. Since the widths of the cardboard boxes are different, when in use, it is necessary to adjust the distance between the two limiting plates 5 according to the width of the cardboard box, so as to prevent the cardboard box from shifting during the conveying process, resulting in a poor fitting effect between the plastic film and the cardboard box. Rotate the threaded rod 4, and the threaded rod 4 will drive the limiting plate 5 to move. Therefore, the limiting plate 5 will move back and forth on the upper side of the conveyor belt 1. It is also possible to make adjustments to the two limiting plates 5 respectively according to needs, so as to be applicable to different scenarios. Then start the conveyor belt 1 to convey the cardboard box. Specific Embodiment Three

[0040] This embodiment is to solve the problem that the plastic film may break.

[0041] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, during the conveying process of the film laminating, since the film laminating may not be conveyed evenly, but the conveying speed of the conveyor belt 1 for the carton and the film laminating is fixed. When less film laminating is conveyed, the film laminating outside the buffer roller 14 will be squeezed, causing the moving plate 12 inside the connecting block 11, the moving plate 12 facing upward to move downward, and the moving plate 12 facing downward to move upward. In addition, the spring 16 will also undergo elastic deformation due to the movement of the cross bar 15 inside the moving plate 12, which is beneficial to the conveying of the film laminating and achieves the purpose of preventing breakage. When the film laminating is conveyed normally, the spring 16 will recover its elastic deformation and let the buffer roller 14 return to its original position again, which is beneficial to preventing problems from occurring during the next conveying. In addition, the limit block 13 at the other end of the moving plate 12 can prevent the moving plate 12 from falling off the connecting block 11 and plays a protective role.

[0042] In addition, the cutting knife 19 on the upper right side of the connecting plate 2 will cut off the connection body of the carton and the film laminating. Start the electric telescopic rod 18, and the electric telescopic rod 18 will drive the cutting knife 19 to move downward, and the cutting operation can be realized. The operation is simple.
