The laminating process is very common in packaging design, which can improve the grade and color performance of products, and has the functions of waterproofing and moistureproofing.
[0003] At present, the surface of the packing paperboard often adheres to a large amount of dust and debris impurities during production and transportation, and the surface of some packing paperboard is uneven, which affects the adhesion of the plastic film on the surface of the packing paperboard, thereby reducing the laminating quality. Therefore, we propose a moistureproof packing paperboard production laminating device. UTILITY MODEL CONTENTS

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by setting up a conveyor frame, exhaust pipe, dust removal hood, brush plate, upper pressure roller, and lower pressure roller, achieves the leveling treatment and removal of dust and debris adhering to the surface of the packaging cardboard before lamination. This results in a smooth and clean surface of the packaging cardboard before lamination, which improves the adhesion of the plastic film to the surface of the packaging cardboard and thus improves the lamination quality. Before entering the laminating machine, the packaging cardboard first passes through the first dust removal hood through the through-hole. The brush plate brushes away the dust and debris adhering to the surface of the cardboard, while the exhaust pipe draws air into the dust removal hood, sucking away the brushed dust and debris. The cleaned cardboard enters between the upper and lower pressure rollers, where the upper and lower pressure rollers flatten the surface of the cardboard. The flattened cardboard then passes through the second dust removal hood through the through-hole, where the surface debris generated during the cardboard leveling is removed. Finally, the clean and flattened cardboard enters the laminating machine for lamination.
[0012] 2. By setting up a gear cover, this utility model can enclose the transmission gear A and transmission gear B to prevent dust and impurities from adhering to the outer surface of the gears, effectively preventing gear wear, and also preventing accidental contact with the gears and causing damage during disassembly.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1-4 As shown, the present invention proposes a moisture-proof packaging cardboard production laminating device, including a conveyor frame 1, a laminating machine 2, and an exhaust pipe 5. The conveyor frame 1 is fixedly installed on one side of the outer surface of the laminating machine 2. The conveyor frame 1 is located near the inlet of the laminating machine 2. The packaging cardboard conveyed by the conveyor frame 1 enters the laminating machine 2 for lamination. Dust removal hoods 8 are fixedly installed on both sides inside the conveyor frame 1. Each dust removal hood 8 has a through-hole 17 on its outer surface. The dust removal hood 8 is passed through both sides of the through-hole 17. Brush plates 16 are fixedly installed on the top and bottom of the inner wall of each dust removal hood 8. When the packaging cardboard passes through the through-hole 17 into the dust removal hood 8, the two brush plates 16 inside the dust removal hood 8 contact the upper and lower surfaces of the packaging cardboard respectively to brush away the dust, impurities, and debris adhering to the surface of the packaging cardboard.
[0020] One end of the exhaust pipe 5 is fixedly connected to a connecting pipe 6, and both ends of the connecting pipe 6 are fixedly connected to branch pipes 7. The two ends of the two branch pipes 7 are respectively fixedly connected to the upper and lower surfaces of the two dust removal hoods 8. An exhaust fan 4 is fixedly installed on the upper surface of the laminating machine 2. A filter 3 is fixedly connected to the input end of the exhaust fan 4, and the end of the filter 3 is fixedly connected to the end of the exhaust pipe 5. The exhaust fan 4 draws away the air inside the dust removal hood 8, and the dust and debris removed by the brush enter the filter 3 with the airflow. The dust and debris are filtered out by the filter 3.
[0021] Inside the conveyor frame 1, several upper pressure rollers 10 and lower pressure rollers 14 are rotatably mounted at equal intervals near the upper and lower surfaces, respectively. Each upper pressure roller 10 and lower pressure roller 14 corresponds to another upper pressure roller 10 and is located between two dust collector hoods 8. A transmission gear A11 is fixedly connected to one end of each upper pressure roller 10 and lower pressure roller 14 near the front surface of the conveyor frame 1. A transmission gear B13 is rotatably mounted on the front surface of the conveyor frame 1 between two adjacent transmission gears A11. The transmission gear B13 is connected to the transmission gear... Gear A11 meshes with each other, and the two adjacent upper pressure rollers 10 and the two adjacent lower pressure rollers 14 are all driven by transmission gear A11 and transmission gear B13. A gear cover 12 is fixedly installed on the front surface of the conveyor frame 1, and the transmission gears A11 and B13 are both located inside the gear cover 12. The gear cover 12 can enclose the transmission gears A11 and B13 to prevent dust and impurities from adhering to the outer surface of the gears, effectively preventing gear wear, and also preventing accidental contact with the gears and causing damage during disassembly.
[0022] A transmission box 9 is fixedly installed on the rear surface of the conveyor frame 1. Rotary gears 19 are fixedly connected to one end of the upper pressure roller 10 and the lower pressure roller 14 located inside the transmission box 9, and the two rotary gears 19 mesh with each other. A rotary motor 15 is fixedly installed on the front surface of the transmission box 9. A motor gear 18 is fixedly connected to the end of the output shaft of the rotary motor 15, and the motor gear 18 meshes with one of the rotary gears 19. The rotary motor 15 drives one of the rotary gears 19 to rotate through the motor gear 18, and the upper pressure roller 10 and the lower pressure roller 14 are transmitted through the meshing rotary gears 19.
[0023] Before the packaging cardboard enters the laminating machine 2 for lamination, it first passes through the through-hole 17 into the first dust removal hood 8. The brush plate 16 brushes away the dust and debris adhering to the surface of the cardboard. At the same time, the exhaust pipe 5 draws air into the dust removal hood 8, and the brushed dust and debris are sucked away. The cleaned cardboard enters between the upper pressure roller 10 and the lower pressure roller 14. The upper pressure roller 10 and the lower pressure roller 14 flatten the surface of the cardboard. The flattened cardboard then passes through the through-hole 17 into the second dust removal hood 8. The second dust removal hood 8 removes the surface impurities generated during the cardboard flattening process. Then, the clean and flattened cardboard enters the laminating machine 2 for lamination, which improves the adhesion of the plastic film to the surface of the packaging cardboard, thereby improving the lamination quality.
