Description

Technical Field

[0001] This utility model belongs to the field of furniture processing technology, and in particular relates to a wood surface painting device for furniture processing. Background Technology

[0002] Roller coating machines are essential devices in furniture manufacturing for painting wood surfaces. They use rolling rollers to evenly apply paint to the wood surface, achieving efficient and precise coating operations. Roller coating machines are characterized by ease of operation and excellent coating results, effectively improving the efficiency and quality of furniture production. Their unique design ensures a close fit between the rollers and the wood surface, guaranteeing even paint coverage of every corner and preventing missed areas or runs. Furthermore, the roller coating machine allows for adjustment of roller pressure and speed to meet different coating requirements and achieve optimal coating results.

[0003] The problem with existing technology is that most existing roller coating machines do not have the function of aligning and cleaning the boards when painting the wood surface. Without the alignment function, the operator needs to manually align the boards when placing them, which increases the labor intensity of the operator. Furthermore, without the cleaning function, there may be residual debris on the top of the board after processing. During the painting process, the debris will mix into the paint layer. When the paint dries, the debris will cause the paint surface to have bumps and a grainy feel, affecting the smoothness and evenness of the paint surface. Utility Model Content

[0036] The above solution is as follows: by setting the movable plate 301, the positioning frame 303 can be moved; by setting the push plate 302 and the extrusion hole 304, the movable plate 301 can be moved; by setting the positioning frame 303 and the contact roller 305, the positioning frame 303 and the movable roller can contact the plate during the movement and push the plate to straighten it.

[0037] refer to Figure 3 and Figure 4 The bottom of the electric cylinder 401 is fixedly connected to the bracket 2, the output shaft of the electric cylinder 401 is fixedly connected to the lifting plate 402, the lower pressure plate 403 is set on the opposite side of the two push plates 302, and the top is fixedly connected to the lifting plate 402.

[0041] The working principle of this utility model:

[0042] In use, place the board to be painted at a suitable position on the top of the roller coating machine 1, and then start the electric cylinder 401 to retract the output shaft, which drives the lifting plate 402 to move downward. During the downward movement of the lifting plate 402, it will drive the lower pressure plate 403 and the connecting column 503 to move downward synchronously. During the downward movement of the lower pressure plate 403, it will drive the pushing column 404 to move in the inner cavity of the extrusion hole 304. During the movement of the pushing column 404, it will squeeze the pushing plate 302. The extrusion force generated at this time will push the two pushing plates 302 to move closer to the board. The pushing plate 302 will drive the moving plate 301 and the positioning frame 303 to move synchronously. When the positioning frame 303 reaches the appropriate position, the contact roller 305 will contact the board to be processed and push the plate 302 to move, so as to straighten the board to be processed, which is convenient for cleaning and painting the surface of the board. After straightening, start the conveyor belt of the roller coating machine 1 to let the board enter the processing area of ​​the roller coating machine 1 for painting.

[0043] As the connecting column 503 moves downward, it drives the support frame 501, brush roller 502, and motor 504 to move downward synchronously. While the board is being aligned, the brush roller 502 also reaches the appropriate position. At this time, the bristles of the brush roller 502 will come into contact with the surface of the board. At the same time, the motor 504 is started, driving the brush roller 502 to rotate. While the board is being conveyed, the surface of the board that needs to be painted is cleaned, making it easier to paint the board.

[0044] In summary, this wood surface painting device for furniture processing, through the coordinated use of the bracket 2, the leveling device 3, the control device 4, the cleaning component 5, and the limiting through hole 6, solves the problem that most existing roller coating machines lack the function of leveling and cleaning the wood surface during painting. Without leveling, operators need to manually level the wood, increasing their workload. Furthermore, without cleaning, residual debris may remain on the top of the wood after processing. During painting, this debris mixes into the paint layer, causing bumps and a grainy texture on the paint surface after drying, affecting the smoothness and evenness of the finish.
