Description

Technical Field

[0001] This application relates to the field of hydrophobic corrugated paper processing technology, and more specifically, to a surface coating device for hydrophobic corrugated paper processing. Background Technology

[0002] In packaging, logistics, and warehousing, corrugated paper remains one of the most widely used packaging materials due to its advantages such as lightweight, high strength, and recyclability. As market demands for the functionality of corrugated paper continue to upgrade, hydrophobic corrugated paper, with its ability to resist humid environments and prevent moisture damage to packaged contents, is increasingly used in food packaging, fresh produce transportation, and outdoor warehousing—scenarios with high moisture-proof requirements. The hydrophobic properties of hydrophobic corrugated paper are primarily achieved through surface coating, where a hydrophobic film is tightly bonded to the corrugated paper substrate using a specific device to form a stable hydrophobic protective layer.

[0003] In related technologies, for example, patent CN213767621U provides a corrugated paper laminating device to prevent corrugated paperboard from shifting. This device includes a conveying base, a limiting mechanism fixedly connected to the front of the conveying base, a laminating mechanism positioned above the limiting mechanism, and a cavity roller on the back of the limiting mechanism. This corrugated paper laminating device, by incorporating springs, bearings, a cavity roller, side rollers, and a connecting frame, and through the coordinated connection of the cavity block, springs, bearings, and cavity rollers, elastically compresses the corrugated paper before laminating, preventing surface wrinkles that could affect the laminating process. Simultaneously, the side rollers and connecting frame limit the sides of the corrugated paper, ensuring stable conveying to the laminating mechanism. This prevents wrinkles and effectively prevents positional shift, thus guaranteeing accurate laminating of the corrugated paper.

[0004] Although the existing technical solutions described above have solved the problems in the background technology, there is a situation where the corrugated paper adheres to the surface of the conveying mechanism during the conveying process. If the impurities on the surface of the corrugated paper are not effectively removed, the impurities will remain on the surface of the corrugated paper during the lamination process, thereby affecting the lamination quality of the corrugated paper.

[0005] In view of this, we propose a surface coating device for hydrophobic corrugated paper processing. Utility Model Content

If the impurities on the surface of the corrugated paper are not effectively removed, the impurities will remain on the surface of the corrugated paper during coating, thus affecting the coating quality. This application achieves the effect of cleaning the debris on the surface of the corrugated paper in advance before coating, so as to avoid the debris affecting the coating quality of the corrugated paper.

[0007] This application provides a surface coating device for hydrophobic corrugated paper processing, comprising a conveyor and a mounting plate; the mounting plate is disposed at one end of the conveyor; a debris cleaning mechanism is provided on the conveyor; a pressure roller mechanism and a film winding mechanism are provided on the mounting plate; support columns are provided on both the conveyor and the mounting plate; the number of support columns is four and they are symmetrically arranged; an anti-slip pad is provided at the lower end of each support column.

[0009] As an optional solution to the technical solution of this application, the pressure roller mechanism includes fixed columns; the fixed columns are disposed on a mounting plate; there are two fixed columns arranged symmetrically; a sliding groove is formed on the fixed column; a fixed block is fixedly disposed at the lower end of the sliding groove; a first rotating roller is rotatably connected to the fixed block; a sliding block is disposed in the sliding groove; a second rotating roller is disposed on the sliding block; a first lead screw is rotatably connected to the fixed block; the first lead screw extends to the outside of the fixed column; the sliding block is threadedly rotatably connected to the first lead screw.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] This application effectively solves the problem of impurities adhering to the surface of the conveying mechanism during corrugated paper conveying due to the adoption of a debris cleaning mechanism, a pressure roller mechanism, and a film winding mechanism. If the impurities on the surface of the corrugated paper are not effectively removed, they will remain on the surface of the corrugated paper during lamination, thus affecting the lamination quality. This application achieves the effect of cleaning the debris on the surface of the corrugated paper in advance before lamination, avoiding the impact of debris on the lamination quality of the corrugated paper.

[0016] This application, through its debris cleaning mechanism, can blow debris away in the opposite direction of the corrugated paper's movement via an inclined pressurized nozzle before lamination, ensuring that the surface of the corrugated paper is free of debris during lamination and preventing debris from affecting the lamination quality.

[0017] In the application of this pressure roller mechanism, during use, the conveyor transports the corrugated paper to the pressure roller mechanism, and the pressure roller mechanism presses the film onto the corrugated paper. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 5 This application discloses a surface coating device for hydrophobic corrugated paper processing, comprising a conveyor 1 and a mounting plate 2; the mounting plate 2 is disposed at one end of the conveyor 1; the conveyor 1 is provided with a debris cleaning mechanism; the mounting plate 2 is provided with a pressure roller mechanism and a film winding mechanism; both the conveyor 1 and the mounting plate 2 are provided with support columns 3; there are four support columns 3 arranged symmetrically; the lower end of the support column 3 is provided with an anti-slip pad 4.

[0026] By setting up a conveyor 1, mounting plate 2, debris cleaning mechanism, pressure roller mechanism, film winding mechanism, support column 3 and anti-slip pad 4, during use, the debris cleaning mechanism is fixed on the conveyor 1, the conveyor 1 conveys the corrugated paper, and at the same time the debris cleaning mechanism cleans the debris on the corrugated paper. Then the film winding mechanism presses one end of the film onto the lower surface of the corrugated paper. When the corrugated paper enters the pressure roller mechanism, it drives the film winding mechanism to rotate, pressing the film onto the upper surface of the corrugated paper.

[0027] Reference Figure 2 and Figure 3 The debris cleaning mechanism includes an installation frame 5; the installation frame 5 is mounted on the conveyor 1; a fan 6 is mounted on the installation frame 5; a venting pipe 7 is mounted below the fan 6; the fan 6 and the venting pipe 7 are connected by a connecting pipe; a pressurizing nozzle 8 is mounted on the venting pipe 7; the pressurizing nozzle 8 is inclined; the number of pressurizing nozzles 8 is several and evenly distributed.

[0028] By setting up the mounting frame 5, fan 6, air duct 7 and booster nozzle 8, in use, the mounting frame 5 is first fixed on the conveyor 1, the fan 6 sends the airflow into the air duct 7, and then the booster nozzle 8 blows the airflow in the opposite direction to the corrugated paper conveying direction to clean the debris on the corrugated paper.

[0029] Reference Figure 4The pressure roller mechanism includes a fixed column 9; the fixed column 9 is mounted on the mounting plate 2; there are two fixed columns 9 arranged symmetrically; a sliding groove 10 is provided on the fixed column 9; a fixed block 11 is fixedly provided at the lower end of the sliding groove 10; a first rotating roller 12 is rotatably connected to the fixed block 11; a sliding block 13 is provided in the sliding groove 10; a second rotating roller 14 is provided on the sliding block 13; a first lead screw 15 is rotatably connected to the fixed block 11; the first lead screw 15 extends to the outside of the fixed column 9; the sliding block 13 is threadedly rotatably connected to the first lead screw 15.

[0030] By setting up a fixed column 9, a sliding groove 10, a fixed block 11, a first rotating roller 12, a sliding block 13, a second rotating roller 14, and a first lead screw 15, in use, the fixed column 9 is fixed on the mounting plate 2, and then the first lead screw 15 is rotated to drive the sliding block 13 to slide up and down in the sliding groove 10, so that the sliding block 13 drives the second rotating roller 14 to move. The width between the first rotating roller 12 and the second rotating roller 14 is changed according to the thickness of the corrugated paper to avoid the distance between the first rotating roller 12 and the second rotating roller 14 being too short, which would cause damage to the corrugated paper.

[0031] Reference Figure 5 The film winding mechanism includes a mounting column 16; the mounting column 16 is disposed on the mounting plate 2 and located on one side of the fixed column 9; a mounting roller 17 is disposed on the mounting column 16; and a film roll 18 is disposed on the mounting roller 17.

[0032] By setting up mounting posts 16, mounting rollers 17, and film rolls 18, during use, mounting posts 16 are fixed on mounting plates 2, and film rolls 18 are fixed on mounting rollers 17, which can rotate with the mounting rollers 17, placing one end of the film on the lower surface of the corrugated paper. As the corrugated paper moves, the film is pressed onto the corrugated paper.

[0033] Reference Figure 2 The mounting frame 5 is threadedly connected to a second lead screw 19; there are four second lead screws 19 arranged symmetrically; one end of the second lead screw 19 is rotatably connected to a limit block 20; a rotating column 21 is rotatably arranged on the limit block 20; the rotating column 21 is made of rubber.

[0034] By setting a second lead screw 19, a limiting block 20, and a rotating column 21, during use, the rotation of the second lead screw 19 drives the limiting block 20 to move, so that the side wall of the corrugated sheet contacts the rotating column 21. The rotating column 21 limits the position of the corrugated sheet, preventing the position of the corrugated paper from changing when the debris on the corrugated paper is blown away.

[0035] Reference Figure 1 The first rotating roller 12 and the conveyor 1 are located on the same horizontal plane.

[0036] By setting the first rotating roller 12 and the conveyor 1 on the same horizontal plane, after the corrugated paper is conveyed, it directly enters between the first rotating roller 12 and the second rotating roller 14.

[0037] Reference Figure 4 The contact surface between the sliding block 13 and the sliding groove 10 is smoothly configured.

[0038] By smoothly configuring the sliding block 13 and the sliding groove 10, the friction between the sliding block 13 and the sliding groove 10 can be reduced, allowing the sliding block 13 to move better in the sliding groove 10.

[0039] In summary, the surface coating device for hydrophobic corrugated paper processing disclosed in this application involves the following steps: First, a debris removal mechanism is fixed to a conveyor 1. The conveyor 1 transports the corrugated paper while simultaneously cleaning debris from the paper. Then, a film winding mechanism presses one end of the film onto the lower surface of the corrugated paper. When the corrugated paper enters the pressure roller mechanism, it rotates, pressing the film onto the upper surface of the paper. A mounting frame 5 is fixed to the conveyor 1. A fan 6 sends airflow into a ventilation duct 7, and a booster nozzle 8 blows the airflow in the opposite direction to the paper transport direction to clean debris. A fixing column 9 is fixed to a mounting plate 2. Rotating the first lead screw 15 causes the sliding block 13 to slide up and down in the sliding groove 10, moving the second rotating roller 14. The width between the first and second rotating rollers 12 and 14 is adjusted according to the thickness of the corrugated paper to avoid... To prevent damage to the corrugated paper caused by an excessively short distance between the first rotating roller 12 and the second rotating roller 14, the mounting column 16 is fixed on the mounting plate 2, and the film roll 18 is fixed on the mounting roller 17, allowing it to rotate with the mounting roller 17. One end of the film is placed on the lower surface of the corrugated paper, and as the corrugated paper moves, the film is pressed onto it. The rotation of the second lead screw 19 drives the limiting block 20 to move, so that the side wall of the corrugated plate contacts the rotating column 21. The rotating column 21 limits the position of the corrugated plate, preventing the position of the corrugated paper from changing when debris is blown on it. By setting the first rotating roller 12 and the conveyor 1 on the same horizontal plane, the corrugated paper directly enters the space between the first rotating roller 12 and the second rotating roller 14 after the corrugated paper is conveyed. Finally, by smoothly setting the sliding block 13 and the sliding groove 10, the friction between the sliding block 13 and the sliding groove 10 can be reduced, allowing the sliding block 13 to move better in the sliding groove 10.
