The pulp then undergoes processes such as forming, dewatering, pressing, and drying to form paperboard. Subsequent post-processing, such as coating, embossing, and cutting, may be carried out to enhance its performance and meet specific requirements.

[0003] After the paperboard is produced, in order to improve its moisture-proof performance, a coating device is usually used to apply moisture-proof coating to the surface of the paperboard. However, the existing coating device has a complex structure and is inconvenient to use, which seriously affects the coating efficiency of paperboard moisture-proof coating.

[0004] To address this, a device for applying moisture-proof coating to cardboard production is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0028] Please see Figure 1-4 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A device for applying moisture-proof coating to cardboard, comprising: a base 1; a first connecting ear 2, a second connecting ear 3, a third connecting ear 6, and a fourth connecting ear 7 symmetrically fixed on the top of the base 1; a first roller 4 movably installed between the first connecting ear 2 and the second connecting ear 3, and a second roller 8 movably installed between the third connecting ear 6 and the fourth connecting ear 7; a conveyor belt 9 installed on the outer wall of the first roller 4 and the second roller 8; a motor 5 installed on the outer wall of the first connecting ear 2, the output end of the motor 5... The first connecting ear 2 passes through and is fixed to the first roller column 4; the top of the base 1 is fixed with a first U-shaped frame 10, the top of the first U-shaped frame 10 is provided with a threaded hole 11, the threaded hole 11 is internally threaded with a threaded rod 12, the top of the threaded rod 12 is fixed with a rotating shaft 13, the bottom of the threaded rod 12 is rotatably connected with a second U-shaped frame 14, the second U-shaped frame 14 is movably installed with an installation roller 15 inside, the outer wall of the installation roller 15 is installed with a paint roller 16, the top of the first U-shaped frame 10 is provided with a movable hole 17, the top of the second U-shaped frame 14 is fixed with a connecting rod 18, and the connecting rod 18 is movably disposed inside the movable hole 17.

[0029] Specifically, this invention pre-applies moisture-proof coating to the coating roller 16, then places the cardboard onto the surface of the conveyor belt 9, and then starts the motor 5. The motor 5 drives the first roller 4, the second roller 8, and the conveyor belt 9 to work. Driven by the conveyor belt 9, the cardboard moves and passes through the coating roller 16. When passing through the coating roller 16, the moisture-proof coating on the coating roller 16 is applied to the cardboard, thereby achieving the purpose of applying moisture-proof coating to the cardboard. Compared with the existing inventions, this invention has a simple structure and is easy to use, thus improving the application efficiency of moisture-proof coating on cardboard.

[0030] Furthermore, by rotating the shaft 13, the threaded rod 12 can be moved within the threaded hole 11. When the threaded rod 12 moves, it will drive the coating roller 16 to move, thereby achieving the purpose of adjusting the height of the coating roller 16. This makes the coating roller 16 suitable for paperboards of different thicknesses, and it has high practicality.

[0031] With the movable hole 17 and connecting rod 18 provided, the paint roller 16 can be limited in position by the cooperation of the connecting rod 18 and the movable hole 17, so as to prevent the paint roller 16 from deviating at an angle during operation and ensure the working efficiency of the paint roller 16. Example 2

[0032] Please see Figure 1-4 This utility model provides a technical solution: a device for applying moisture-proof coating to cardboard production. A second U-shaped frame 14 has an installation hole 26 on its outer wall. A bearing 25 is installed inside the installation hole 26. A connecting column 19 is movably connected inside the bearing 25. An abutment plate 20 is fixed to one end of the connecting column 19. A telescopic rod 21 is fixed to one end of the abutment plate 20. One end of the telescopic rod 21 is fixed to an installation roller 15. A spring 22 is provided on the outer wall of the telescopic rod 21. One end of the spring 22 is fixed to the abutment plate 20, and the other end of the spring 22 is fixed to the installation roller 15. An annular groove 23 is provided on the inner wall of the second U-shaped frame 14. A slider 24 is installed inside the annular groove 23, and the abutment plate 20 abuts against the slider 24.

[0033] Specifically, by squeezing the connecting column 19, the spring 22 and the telescopic rod 21 will retract accordingly. After the connecting column 19 is disengaged from the bearing 25, the paint roller 16 can be disassembled, which facilitates the maintenance and cleaning of the paint roller 16 and ensures the working efficiency of the paint roller 16.

[0034] Working principle:

[0035] Workers apply moisture-proof coating to the coating roller 16 beforehand, then place the cardboard onto the conveyor belt 9 and start the motor 5. The motor 5 drives the first roller 4, the second roller 8, and the conveyor belt 9. Driven by the conveyor belt 9, the cardboard moves and passes over the coating roller 16. As it passes over the coating roller 16, the connecting column 19, bearing 25, and coating roller 16 roll accordingly. With the cooperation of the annular groove 23 and the slider 24, friction between the contact plate 20 and the second U-shaped frame 14 is avoided. Subsequently, the moisture-proof coating on the coating roller 16 is applied to the cardboard, thus achieving the purpose of applying moisture-proof coating. Workers can adjust the height of the coating roller 16 according to the thickness of the cardboard by rotating the rotating shaft 13. The movable threaded rod 12 moves within the threaded hole 11, driving the coating roller 16 to move as it moves, thereby adjusting the height of the coating roller 16. This allows the coating roller 16 to be used with cardboard of different thicknesses, making it highly practical. The movable hole 17 and connecting rod 18, in conjunction with each other, limit the movement of the coating roller 16, preventing angular deviation during operation and ensuring its working efficiency. By pressing the connecting column 19, the spring 22 and telescopic rod 21 retract accordingly. Once the connecting column 19 disengages from the bearing 25, the coating roller 16 can be disassembled, facilitating maintenance and cleaning, and ensuring its continued high working efficiency.
