Description

Technical Field

[0001] This utility model relates to the field of decorative paper coating technology, specifically a precision coating device for a furniture board decorative paper coating machine. Background Technology

[0002] Furniture board decorative paper is a type of paper used for decorating the surface of furniture boards. Decorative paper can provide various colors, patterns, and textures to meet different design needs, enhance the appearance and use value of furniture, and at the same time, prevent furniture boards from being corroded by the external environment, such as moisture, sunlight, and wear, thus extending the service life of furniture. It avoids the complex processes of painting and spraying in traditional furniture making, improves production efficiency, and reduces production costs. Coating equipment is a device used to coat liquid or powder materials on the surface of various substrates.

[0003] Coating devices are required in the production of decorative paper. Chinese utility model patent CN213207123U discloses a coating device for release paper, including a coating device, a base, a shock-absorbing plate, a slider, and a shock-absorbing rod. The base is fixedly mounted on the bottom side of the coating device, with an opening at the top. The bottom end of the coating device extends into the inner cavity of the base. The shock-absorbing plate is bolted to the bottom end of the coating device. A slide rail is integrally formed at the bottom end of the inner cavity of the shock-absorbing plate, and a slider is fixedly mounted on the outer wall of the slide rail. This utility model features a base at its bottom end that provides shockproof, moisture-proof, and corrosion-proof functions, ensuring that the bottom of the coating device is not affected by vibration, moisture, corrosion, or other factors. This allows the coating device to operate normally during production without causing shutdowns or production stoppages during the release paper coating process, thus protecting the company's interests and extending the product's lifespan.

[0004] This invention ensures that the bottom of the coating device is unaffected by factors such as vibration, moisture, and corrosion. However, existing coating devices do not have a rolling coating function, which results in the coating material not being able to evenly cover the outer surface of the paper, leading to poor coating effect. Therefore, a precision coating device for furniture board decorative paper coating machine is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 4The precision coating device of the furniture board decorative paper coating machine in this embodiment includes a coating frame 1. A coating mechanism for left-right rolling and uniform coating is provided inside the coating frame 1. The coating mechanism includes a cylinder 2 fixedly connected to the top of the coating frame 1. A mounting frame 3 is fixedly connected to the output shaft of the cylinder 2. A servo motor 4 is fixedly connected to the left side of the mounting frame 3. A lead screw 5 is fixedly connected to the output shaft of the servo motor 4. A moving block 6 is threaded onto the outer surface of the lead screw 5. A moving rod 7 is fixedly connected to the inner side of the mounting frame 3. A rolling frame 8 is fixedly connected to the bottom of the moving block 6. A roller 9 is rotatably connected to the inner side of the rolling frame 8. A heating box 10 is fixedly connected to the inner side of the rolling frame 8. The left and right sides of the inner wall of the heating box 10 are fixedly connected to... An electric heating plate 11 is connected to the heating box 10. Connecting arms 12 are fixedly connected to the left and right sides of the heating box 10. A manifold box 13 is fixedly connected to the bottom of the connecting arms 12. A flow pump 14 is fixedly connected to the top of the manifold box 13. A nozzle 15 is fixedly connected to the bottom of the manifold box 13. The electric heating plate 11 can continuously heat the paint to prevent the paint from solidifying. The flow pump 14 can draw the paint inside the heating box 10 and guide it into the manifold box 13. Then, it is sprayed onto the outer surface of the roller 9 through the nozzle 15 to ensure that the paint can be evenly distributed on the roller 9.

[0026] The servo motor 4 can drive the lead screw 5 to rotate clockwise or counterclockwise, thereby driving the roller 9 inside the rolling frame 8 to roll back and forth on the outer surface of the paper through the moving block 6, so that the coating is evenly covered on the outer surface of the paper and the coating effect is good.

[0027] In this embodiment, a drying box 16 is fixedly connected to the bottom of the coating rack 1. Hot air blowers 17 are installed on both the left and right sides of the inner wall of the drying box 16. A slide rail 18 is fixedly connected to the inner side of the drying box 16. A tray 19 is slidably connected to the inner side of the slide rail 18. The operator can put the coated paper into the tray 19, and then blow hot air out by the hot air blower 17 to dry it with hot air, thereby accelerating the coating coagulation speed and preventing coating loss.

[0028] It should be noted that the front of the drying oven 16 is hinged with a sealing door 20, and the back of the sealing door 20 is glued with a sealing strip. The sealing door 20 can ensure the airtightness of the drying oven 16, thereby reducing heat loss.

[0029] Specifically, there are two moving rods 7, and the moving block 6 is slidably connected to the moving rods 7. The moving rods 7 serve to limit the moving block 6.

[0030] It should be noted that the inlet and outlet pipes of the diversion pump 14 are connected to the heating box 10 and the manifold 13, respectively. The drum 9 has a hollow structure, and the diversion pump 14 plays the role of sucking up the paint and pressurizing it.

[0031] Specifically, feed pipes are fixedly connected to both the left and right sides of the heating box 10, and screw caps are threaded onto the outer surface of the feed pipes.

[0032] It should be noted that a coating platform 21 is fixedly connected to the inner side of the coating rack 1. Limiting plates 22 are fixedly connected to the left and right sides of the top of the coating platform 21. The limiting plates 22 of the coating platform 21 can limit the position of the paper.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the operator first places the paper on top of the coating platform 21, positioning it between the two limiting plates 22. Then, the electric heating plate 11 is activated to continuously heat the coating, preventing it from solidifying. During this process, the diversion pump 14 is turned on to extract the coating from the heating box 10 and guide it into the manifold 13. The coating is then sprayed onto the outer surface of the roller 9 through the nozzle 15, ensuring that the coating is evenly distributed on the roller 9. Finally, the cylinder 2 is activated, which drives the roller 9 to move vertically downwards and closer to the paper via the mounting bracket 3, so that the bottom of the roller 9 is pressed against the top of the paper. At this time, the servo motor 4 is activated, which drives the lead screw 5 to rotate clockwise or counterclockwise. This, in turn, drives the roller 9 inside the rolling frame 8 to roll back and forth on the outer surface of the paper via the moving block 6, thereby ensuring that the coating is evenly covered on the outer surface of the paper.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
