Description

A fully automatic laminating machine for gift box production Technical Field

[0001] This utility model relates to the technical field of gift box production equipment, and in particular to a fully automatic laminating machine for gift box production. Background Technology

[0002] The fully automatic laminating machine is a highly efficient and intelligent piece of equipment primarily used for surface lamination of printed materials and packaging materials. By precisely bonding plastic film to the substrate, it enhances the product's waterproofness, abrasion resistance, and aesthetics. Its core processes include automatic feeding, gluing, pressing, and winding, all monitored in real-time by a PLC control system and sensors to ensure uniform lamination without air bubbles. The equipment is compatible with various film materials and paper types, supports both cold and hot lamination modes, and can process tens of thousands of sheets per day. It features a touchscreen interface, automatic fault diagnosis, and energy-saving modes, significantly reducing manual intervention and consumable consumption. Widely used in advertising printing, bookbinding, and gift packaging, it is a key piece of equipment for improving the quality and efficiency of modern printing production lines.

[0003] Research revealed that traditional equipment often employs intermittent conveying, resulting in poor coordination between processes. It relies heavily on manual loading, unloading, and process transfer, leading to low automation. Furthermore, the laminating and pressing mechanisms typically involve single-point pressure application or rigid pressing of boards or rollers before curing, easily causing uneven local pressure. Areas with concentrated pressure are prone to glue extrusion or overpressure, while edge areas suffer from poor adhesion and air bubble residue due to pressure attenuation. After curing, the surface tension of the glue further contributes to poor edge adhesion, requiring manual secondary repairs, severely impacting lamination smoothness and finished product yield. Therefore, a fully automatic laminating machine for gift box production is proposed to address these issues. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0027] Referring to Figures 1 to 4, in this embodiment of the present utility model, a fully automatic laminating machine for gift box production includes: an operating table 1;

[0028] The film laminating mechanism 4 is set above the operating table 1 and is used to tightly bond the film to the gift box cardboard.

[0029] The gift box cardboard dispensing mechanism 8 is set above the operating table 1 and is used to evenly dispense glue onto the surface of the gift box cardboard.

[0030] The laminating mechanism 4 includes an outer shell 41, with a hot air blower 42 mounted on top of the outer shell 41. The outer shell 41 is designed with a sealed top and an open bottom. The air outlet of the hot air blower 42 extends into the inner cavity of the outer shell 41. Four sets of sliding rod grooves 43 are provided on the inner side wall of the outer shell 41. One end of a support spring 44 is fixedly connected to the inner side of the sliding rod groove 43. The other end of the support spring 44 is fixedly connected to a pressure roller bracket 45. A pressure roller 46 is rotatably connected to the inner side of the pressure roller bracket 45. Two sets of sliding rods are provided above each set of pressure roller brackets 45. The sliding rods above each set of pressure roller brackets 45 are fixedly connected to the other end of the support spring 44 on the inner side of a set of sliding rod grooves 43. Fixed plates 47 are symmetrically fixedly connected to both sides of the outer shell 41. A first electric telescopic rod 48 is provided below the fixed plate 47. The first electric telescopic rod 48 is embedded in the inner side of the operating table 1. The movable end of every two sets of the first electric telescopic rods 48 extends through the operating table 1 and is fixedly connected to a set of fixed plates 47.

[0031] Using the above scheme: the support springs 44 in the four sets of slide bar grooves 43 push the pressure roller bracket 45 through the slide bars to form a synchronous elastic pressing at the four corners. The ballast roller 46 achieves dynamic bonding in conjunction with the spring pressure during rotation. The first electric telescopic rod 48 adjusts the overall height of the outer shell 41 through the fixing plate 47, so that the ballast roller 46 can be adapted to gift box cardboard of different thicknesses, and facilitates the initial position installation of the film and gift box cardboard. The hot air blower 42 forms a closed hot air chamber through the outer shell 41 to cure the adhesive between the film and the gift box cardboard.

[0032] The gift box cardboard dispensing mechanism 8 includes a film roller bracket 81, a film-applying roller 82 is provided inside the film roller bracket 81, a glue storage box 83 is fixedly connected to the inside of the film roller bracket 81 below the film-applying roller 82, a second electric telescopic rod 84 is fixedly connected to the bottom of the glue storage box 83, a baffle plate 85 is slidably connected to the bottom of the glue storage box 83 and the inside of the baffle plate 85, and glue leakage holes of appropriate size and position are opened below the glue storage box 83 and inside the baffle plate 85. The movable end of the second electric telescopic rod 84 is fixedly connected to the baffle plate 85.

[0033] Using the above scheme: the glue storage box 83 allows the glue to flow naturally downwards under gravity, the second electric telescopic rod 84 drives the baffle plate 85 to slide laterally, and the glue dispensing amount is controlled by the degree of misalignment of the glue leakage holes. When the baffle plate 85 is fully aligned, the glue holes are fully open, and when misaligned, the glue amount is reduced, thus realizing stepless adjustment of the glue layer thickness. The film-applying roller 82 and the glue storage box 83 maintain a fixed distance to ensure that the glue forms a uniform glue layer when the film is spread out.

[0034] It also includes a conveyor belt 5, which is set above the operating table 1, and a glue storage box 83 is set above the starting section of the conveyor belt 5;

[0035] Using the above scheme: the conveyor belt 5 is set with a conveying plane along the length of the operating table 1. The gift box cardboard first passes through the glue storage box 83 at the beginning of the conveyor belt 5 to complete the glue dispensing process, and then is conveyed to the laminating mechanism 4 for lamination processing, forming a continuous process of glue dispensing, lamination, initial lamination pressure (the first set of pressure rollers 46 ensures the subsequent curing effect), hot air curing, and finally secondary lamination pressure to strengthen the lamination effect. Each process segment is precisely connected by the conveyor belt 5.

[0036] The working principle of this utility model is as follows: After the gift box cardboard is fed into the conveyor belt 5, it first passes through the glue storage box 83 below the glue dispensing mechanism 8. The glue storage box 83 uses gravity to make the glue drip evenly onto the cardboard surface through the glue leakage hole. The second electric telescopic rod 84 drives the baffle plate 85 to slide laterally. By adjusting the misalignment of the glue leakage hole, the thickness of the glue layer is controlled to ensure that the glue is evenly distributed. The cardboard that has completed the glue dispensing moves with the conveyor belt 5 to the underside of the laminating mechanism 4. At this time, the laminating roller 82 simultaneously unfolds and applies the film to cover the surface of the glued cardboard.

[0037] When the cardboard reaches directly below the laminating mechanism 4, the first electric telescopic rod 48 drives the outer shell 41 to descend to the set height. The pressure roller bracket 45 pushes the pressure roller 46 to perform the initial lamination and pressure on the film and cardboard. The support spring 44 ensures that the pressure roller 46 and the film are tightly pressed and the pressure is uniform, ensuring that the film and the adhesive layer are initially bonded. At the same time, the hot air blower 42 delivers hot air into the inner cavity of the closed outer shell 41 to heat-cure the adhesive. Subsequently, the conveyor belt 5 continues to transport the cardboard. The pressure roller 46 inside the outer shell 41 continues to roll and advance to the second set of pressure rollers 46 for secondary lamination and pressure, further eliminating air bubbles and strengthening the lamination effect. Here, the support spring 44 can ensure that the pressure roller 46 can adapt to different adhesive layer thicknesses. Finally, the laminated gift box cardboard is output through the end of the conveyor belt 5, realizing the fully automated production process of glue dripping, lamination, heat curing and double pressure.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
