Description

Technical Field

[0001] The utility model relates to the technical field of packaging color box laminating, in particular to a packaging laminating machine. Background Art

[0002] In the modern packaging industry, color boxes, as a crucial outer layer of a product, must not only provide excellent protection but also enhance brand image and consumer experience through exquisite surface treatment. Laminating machines, a key piece of equipment in color box production, apply a transparent film to the surface of printed materials, imparting enhanced wear resistance, moisture resistance, and gloss, making the product more visually appealing on the shelf. As consumer demand for packaging quality continues to rise, laminating has become widely used in the production of color boxes for a wide range of products, including food, cosmetics, and electronics, becoming an essential process for high-end packaging.

[0003] After searching, the utility model patent with the authorization announcement number CN222203031U is a laminating machine for packaging box processing, which includes a workbench, a laminating execution component is arranged above the workbench, and a feeding and rewinding mechanism is arranged on both sides of the laminating execution component. The laminating execution component is set to effectively guide and position the packaging box for lamination. The front and rear side movable frames and the telescopic plate set above the conveyor belt drive the guide wheels to guide the packaging box, and the electric telescopic rod drives the telescopic plate and the guide wheels to clamp and position the packaging box. At the same time, the packaging box is softly guided and protected by the soft protection component. The lifting hydraulic cylinder is opened to drive the sealing pressure plate to preheat and press, and the cutting knife is used to cut the film. It is automatically aligned with the packaging box and laminated. At the same time, the film is cut and preheated and pressed on the laminated packaging box. It is easy to use, has good automatic consistency, and high production efficiency.

[0038] Reference Figure 7-8 Specifically, the bottom of the support block 12 is set to be L-shaped, and the top of the support block 12 is set to be hollow.

[0039] Reference Figure 2 、 Figure 4-6 Specifically: the cutting assembly includes a fixed rod 23 fixedly mounted on the frame 1, a mounting plate 24 fixedly mounted on the lower surface of the fixed rod 23, a motor 25 fixedly mounted on one side of the mounting plate 24, and two symmetrical synchronous wheels 26 rotatably mounted on the other side of the mounting plate 24, the output end of the motor 25 is fixedly connected to one of the synchronous wheels 26, a synchronous belt 27 is transmission-connected between the synchronous wheels 26, a clamping block 28 is sleeved on the synchronous belt 27, a knife seat 29 is fixedly mounted on the lower surface of the clamping block 28, a blade 30 is fixedly mounted on the knife seat 29, a slide rail 31 is fixedly mounted on the other side of the mounting plate 24, a slider 32 is slidably mounted on the slide rail 31, and the slider 32 is fixedly connected to the clamping block 28;

[0040] When the printing material is transported to the bottom of the cutting component, the motor 25 drives the synchronous wheel 26 to rotate, and the clamping block 28 is driven by the synchronous belt 27 to cut the excess film through the blade 30 connected below it. When the clamping block 28 moves, the slider 32 and the slide rail 31 accurately guide it to ensure the accuracy of cutting.

[0041] Reference Figure 2-3 Specifically, the housing 2 is provided with a rectangular slot 33 for accommodating the movement of the blade 30 .

Two support rods 36 are fixedly installed on the frame 1. One end of the connecting rod 35 passes through the support rod 36 and is slidably connected thereto. A fixing sleeve 37 is fixedly installed on the outside of the connecting rod 35, and a second spring 38 is fixedly installed between the fixing sleeve 37 and the support rod 36;

[0043] In order to avoid the problem of wrinkles when cutting the film, the two sets of pressure wheels 34 on both sides of the blade 30 can press the laminated substrate in real time, and through the elastic deformation of the second spring 38 and the sliding characteristics of the connecting rod 35, they can adapt to substrates of different thicknesses to ensure the flatness of the film cutting.

[0044] Reference Figure 2 Specifically: a guide rod 39 is fixedly installed on the upper surface of the cross bar 8, and one end of the guide rod 39 passes through the lifting block 7 and is slidably connected thereto.

[0045] Working Principle: After the film is unwound from the barrel 10, it first passes through the electrostatic dust removal roller 11. High-voltage electrostatic adsorption and physical contact thoroughly remove dust and paper powder on the film surface to ensure the cleanliness of the laminating surface. The film then enters the area of ​​the first electric heating roller 4. Under the adjustment of the lifting block 7 controlled by the cylinder 9, the first electric heating roller 4 accurately preheats the upper surface of the film. The preheated film and the substrate on the belt conveyor 3 form a laminated structure under the action of the pressing force. The laminated substrate is then conveyed to the area of ​​the second electric heating roller 5 to remove excess solvent and formaldehyde residues. Finally, it is quickly shaped by the cooling roller 6.

[0046] When the printed material is conveyed to the bottom of the cutting assembly, the motor 25 drives the synchronous wheel 26 to rotate, and the clamping block 28, driven by the synchronous belt 27, cuts the excess film through the blade 30 connected below it. When the clamping block 28 moves, the slider 32 and the slide rail 31 accurately guide it to ensure the accuracy of cutting. In order to avoid the problem of wrinkles when cutting the film, the two sets of pressure wheels 34 on both sides of the blade 30 can press the laminated printed material in real time. The elastic deformation of the second spring 38 and the sliding characteristics of the connecting rod 35 can adapt to substrates of different thicknesses to ensure the flatness of the film cutting.

[0047] When the second gear 15 on the material roller 14 is meshed with the first gear 13, the roller 18 is now in the upper half area of ​​the material roller 14, and the first spring 21 is reset and drives the roller 18 to press the outer side of the material roller 14. When the material roller 14 is unwinding and rotating, the roller 18 can rotate synchronously along its outer surface and cooperate with the first gear 13 to limit the material roller 14 up and down. Through the setting of the annular groove 22, the roller 18 can move into it, thereby limiting the material roller 14 left and right, ensuring the unwinding stability of the material roller 10 while also meeting the purpose of quick installation of the material roller 10. When removing the material roller 10, you only need to lift the material roller 10 upward.
