Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of furniture board painting, in particular to a roller coating device for furniture boards that can be painted evenly. Background Art
[0002] Furniture panels, especially solid wood panels, are hard, but they are easily scratched or worn by sharp objects when exposed to the outside for a long time, affecting their appearance and service life. Therefore, they need to be painted, which is equivalent to putting a protective layer on the panels to effectively prevent these physical damages.
[0003] The industry generally uses spray painting to apply paint to panels. However, due to the limited spray range and angle of the spray gun or nozzle, as well as the diffusion and dispersion of the paint in the air, spraying accuracy is relatively difficult to control. This can result in uneven distribution of paint on the panel surface, with areas of paint being too thick or too thin. Utility Model Content
[0004] Based on this, the utility model provides a roller coating device for evenly painting furniture panels. It has a simple structure and is easy to use. Coating rollers are installed in parallel and at intervals below each driving roller. The coating rollers are driven by tension springs to always approach the driving rollers. The coating rollers can always be in close contact with the surface of the panel, and the paint is evenly exuded and coated on the surface of the panel, ensuring the uniformity of the coating.

[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.
[0027] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] See also Figures 1 to 7 , which is a roller coating device for evenly painting furniture panels according to one embodiment of the present invention, includes a frame 10, a transmission assembly 20 installed on the top of the frame 10, and a roller coating assembly 30 installed inside the frame 10.
[0030] The conveying assembly 20 includes a transmission roller 21 rotatably mounted on opposite sides of the top of the frame 10, a reduction gearbox 22 mounted on the top of one side of the frame 10, and a motor 23 mounted on the bottom of one side of the frame 10; the motor 23 is used to connect to the input end of the reduction gearbox 22, and the output end of the reduction gearbox 22 is connected to the transmission roller 21, and the transmission roller 21 is used to abut against and convey the plate.
[0031] Specifically, if Figure 1As shown, the input end of the reduction box 22 is coaxially connected to the driven wheel 220, and the rotor of the motor 23 is coaxially connected to the driving wheel 230. The driving wheel 230 and the driven wheel 220 are connected through a synchronous belt 24 to realize the connection between the motor 23 and the reduction box 22.
[0032] The roller coating assembly 30 includes a paint container 31 mounted at the bottom end of the frame 10, a supply pump 32 mounted within the paint container 31, coating rollers 33 mounted parallel and spaced apart below each drive roller 21, deflection levers 34 hinged to opposite ends of each coating roller 33, tension springs 35 connecting each deflection lever 34 to the frame 10, and a rotary joint 36 rotatably connected to one end of each coating roller 33. The rotary joint 36 is downwardly connected to the supply pump 32 via a hose (not shown). Each deflection lever 34 is hinged to the frame 10 at one end away from the coating roller 33.
[0033] In this embodiment, if Figure 5 As shown, the spacing between the two coating rollers 33 is smaller than the spacing between the two drive rollers 21; the space between the coating rollers 33 and the drive rollers 21 allows the sheet material to pass through. The coating rollers 33 are in contact with the sheet material's surface, and the tension spring 35 forces the coating rollers 33 toward the drive rollers 21 to better conform to the sheet material's surface. The tension spring 35 continuously applies a force toward the drive rollers 21. This ensures that, regardless of the sheet material's thickness, the coating rollers 33 maintain close contact with the sheet material's surface, ensuring uniform coating.
[0034] In actual operation, when the supply pump 32 is activated, it draws paint from the paint container 31 and pumps it through the hose and rotary joint 36 to the interior of the coating roller 33. Once the paint is pumped into the coating roller 33, the rotating coating roller 33 comes into contact with the surface of the sheet material, causing the paint to evenly seep out and be applied to the surface of the sheet material, completing the painting process.
[0035] like Figure 6 and Figure 7 As shown, in this embodiment, the coating roller 33 includes a hollow inner roller body 331 and a coating cotton 332 coaxially sleeved on the outside of the inner roller body 331; a plurality of openings 333 are evenly spaced on the surface of the inner roller body 331, and the openings 333 are connected to the interior of the inner roller body 331, so that the paint can penetrate into the coating cotton 332 after passing through the openings 333, and the coating cotton 332 is used to contact the surface of the plate to achieve painting.
[0036] The above-mentioned roller coating equipment for evenly painting furniture panels has a simple structure and is easy to use. Coating rollers 33 are installed in parallel and at intervals below each driving roller 21. The coating rollers 33 are driven by tension springs 35 to always approach the driving rollers 21. The coating rollers 33 can always be in close contact with the surface of the panel, and the paint is evenly exuded and applied to the surface of the panel, ensuring the uniformity of the coating.
[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
