Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Example 1

[0030] This utility model provides a packaging box paper laminating device to reduce dust problems during the laminating process.

[0031] Please see Figure 1The packaging box paper sheet laminating device provided in this utility model embodiment includes: a conveyor belt 111, with limiting plates 112 symmetrically arranged on both sides of the conveyor belt 111. The limiting plates 112 and the conveyor belt 111 enclose a U-shaped channel for accommodating the packaging box. The conveyor belt 111 is used to carry and transport the packaging box paper sheet to be laminated, ensuring that the paper sheet can move smoothly along the set direction. The conveyor belt 111 is provided with a support member to ensure that it is stably supported on the ground. The limiting plates 112 are arranged on both sides of the conveyor belt 111, and together with the conveyor belt 111, they enclose a U-shaped channel to help position the paper sheet and prevent it from shifting during the transport process.

[0032] A coating roller 121 is located directly above the conveyor belt 111, with its axis perpendicular to the direction of travel of the conveyor belt 111. It is used to fix one end of the rolled film and provide a fixed position for the film.

[0033] The extrusion rollers 1221 are arranged vertically above the conveyor belt 111 and are located in front of the coating rollers 121 along the conveying direction of the conveyor belt 111. The drive motor is connected to the extrusion rollers 1221 and is provided with a support base fixed to the ground. The drive motor drives the extrusion rollers 1221 to rotate, thereby completing the coating work of the paper sheet and ensuring that the film is evenly covered on the paper sheet to avoid the generation of bubbles or wrinkles.

[0034] The heating assembly includes a heating air pipe 131 located above the conveyor belt 111. The vertical height of the heating assembly is higher than the height of the coating roller 121. The heating assembly is located between the extrusion roller 1221 and the coating roller 121. By heating the film, the film reaches a suitable temperature before coating, which facilitates subsequent operations.

[0035] The dust removal assembly includes a dust removal pipe disposed inside the limiting plate 112. The dust removal pipe extends along the length of the limiting plate 112 and has a dust removal port 1411 facing the paper sheet of the packaging box. It can effectively absorb dust and other small particles on the surface of the paper sheet to ensure the quality of the coating. The dust removal pipe is connected to a blower.

[0036] In this embodiment, a cooling component is also included. The cooling component includes a cooling air pipe 151 located in front of the extrusion roller along the conveyor belt 111 conveying direction. The cooling air pipe 151 is set at an angle to the conveyor belt 111 to quickly cool the coated paper sheet, which helps the film to be quickly fixed on the paper sheet, reduces the risk of deformation, and improves the durability of the product. The cooling air pipe 151 is connected to a cold air source.

[0037] In this embodiment, the extrusion roller 1221 is connected to a drive motor, which drives the extrusion roller 1221 to rotate around its own axis through a gear transmission mechanism. The drive motor is provided with a support for supporting the ground.

[0038] In this embodiment, the coating roller 121 and the extrusion roller 1221 are respectively installed by an adjustable support frame 1211. The adjustable support frame 1211 is provided with a height adjustment support rod and a locking nut. Specifically, the height adjustment support rod of the adjustable support frame includes an upper sleeve rod and a lower sleeve rod. The two sleeve rods have multiple locking threaded holes spaced apart in the vertical direction at corresponding positions. The locking nut can be selectively installed in the locking threaded holes to realize the installation of the upper sleeve rod and the lower sleeve rod, and realize the height adjustment operation of the height adjustment support rod.

[0039] In this embodiment, the dust removal ports 1411 are arranged in an alternating pattern on the dust removal pipe.

[0040] In this embodiment, the inner surface of the limiting plate 112 is provided with a wear-resistant ceramic layer.

[0041] In this embodiment, a dust collection component is also included, including a dust collection pipe disposed inside the limiting plate 112 on the other side. The dust collection pipe extends along the length of the limiting plate 112 and is provided with a dust collection port facing the paper of the packaging box. The dust collection pipe is connected to an exhaust fan.

[0042] The following is a detailed description of the usage process of the packaging box paper laminating device of Embodiment 1 of this utility model:

[0043] The paper sheet to be laminated is placed on the conveyor belt 111. The paper sheet moves smoothly along the U-shaped channel formed by the limiting plate 112. The limiting plate 112 helps to position the paper sheet and prevent it from shifting during the conveying process. When the paper sheet passes through the dust removal component, the staggered dust removal ports 1411 blow away the dust and other small particles on the surface of the paper sheet. The dust suction component picks up the dust to ensure that the surface of the paper sheet is clean before lamination. One end of the rolled film is fixed on the laminating roller 121, and the other end is stretched to the extrusion roller 1221, passing between the two extrusion rollers 1221. Since the heating component is arranged vertically above the laminating roller 121 and horizontally between the extrusion roller 1221 and the laminating roller 1221, the heating component is also positioned. During the process, the film located between the extrusion roller 1221 and the coating roller 121 is heated to prepare for subsequent coating. The conveyor belt 111 carries the paper sheet into the two extrusion rollers 1221 in the extrusion assembly. The extrusion action completes the coating of the paper sheet, ensuring that the film can be evenly covered on the paper sheet and avoiding the formation of bubbles or wrinkles. The drive motor drives the extrusion roller 1221 to rotate through the gear transmission mechanism, ensuring the continuity and stability of the coating process. After the coating is completed, the paper sheet passes through the cooling assembly area. The cooling air pipe 151 quickly cools the coated paper sheet, which helps the film to be quickly fixed on the paper sheet, reduces the risk of deformation, and improves the durability of the final product.
