[0002] Furniture manufacturing board painting equipment is a specialized device used to uniformly spray paint onto the surface of furniture boards, improving the appearance and protective performance of the boards, ensuring spraying efficiency and quality, and meeting the needs of furniture production processes.

[0003] Traditional panel painting relies heavily on manual handling of panels in and out of the painting equipment, which is labor-intensive, inefficient, and prone to errors, disrupting production schedules. Furthermore, the coordination between panel movement and paint application is insufficient in traditional methods, often resulting in uneven paint coverage and inconsistent coating quality. This affects product appearance, prolongs painting time for individual panels, and limits overall production efficiency.

[0004] In view of this, this application proposes a panel painting device for furniture manufacturing. Utility Model Content

[0005] The purpose of this application is to provide a furniture manufacturing board painting device, which solves the technical problems mentioned in the background art.

[0006] This application provides a painting device for furniture manufacturing boards, including an inclined paint spraying box with a through-hole on the upper surface of the spraying box. The paint spraying box contains a painting assembly. The painting assembly includes a grid plate fixedly connected to the inside of the paint spraying box, a placement plate on the upper part of the inside of the paint spraying box, a support strip fixedly connected to one side of the lower end of the placement plate, a threaded rod and a limiting rod respectively on one side of the upper part of the inside of the paint spraying box, a painting strip fixedly connected to the other side of the upper inner wall of the paint spraying box, a feeding pump fixedly connected to one side of the lower surface of the grid plate, a suction pipe fixedly inserted into the lower end of the feeding pump, and a counterweight head fixedly connected to one end of the suction pipe.

[0007] Optionally, the two ends of the threaded rod are rotatably connected to the upper part of the paint spray box and the grid plate, respectively, and the two ends of the limiting rod are fixedly connected to the upper part of the paint spray box and the grid plate, respectively.

[0008] Optionally, the outer wall of the threaded rod is rotatably connected to a movable block via a thread, and the outer wall of the limiting rod is slidably connected to a sliding block. One end of the movable block and the sliding block are fixedly connected to the lower part of the outer wall of the placement plate, and the other end of the movable block and the sliding block are in contact with one side of the inner wall of the paint spray box.

[0009] Optionally, a connecting pipe is fixedly inserted into the upper end of the feed pump, and the upper end of the connecting pipe passes through the grid plate and is fixedly connected to the paint spraying strip.

[0010] Optionally, a servo motor is fixedly connected to the other side of the lower end face of the grid plate, and the output end of the servo motor is fixedly connected to the threaded rod.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 This application provides a furniture manufacturing board painting device, including an inclined paint spraying box 1. A connecting opening 2 is provided through the upper surface of the paint spraying box 1. A paint spraying assembly 5 is provided inside the paint spraying box 1. The paint spraying assembly 5 includes a grid plate 501 fixedly connected inside the paint spraying box 1. A placement plate 502 is provided at the top inside the paint spraying box 1. A support strip 503 is fixedly connected to one side of the lower end of the placement plate 502. A threaded rod 504 and a limiting rod 506 are respectively provided on one side of the upper part of the paint spraying box 1. The other side of the upper part of the inner wall of the paint spraying box 1... A paint spraying strip 508 is fixedly connected to the paint spraying system. A feed pump 509 is fixedly connected to one side of the lower end of the grid plate 501. A suction pipe 510 is fixedly inserted into the lower end of the feed pump 509. One end of the suction pipe 510 is fixedly connected to a counterweight head 511. The counterweight head 511 ensures that one end of the suction pipe 510 is always at the bottom, allowing the paint to be smoothly extracted. During the spraying process, splashed paint falls through the grid plate 501 and flows back to the bottom of the paint spraying box 1, where it is recycled through the feed pump 509, suction pipe 510, and other components. This design greatly reduces paint waste and lowers the company's paint procurement costs.

[0021] Both ends of the threaded rod 504 are rotatably connected to the upper interior of the paint spray box 1 and the grid plate 501, respectively. Both ends of the limiting rod 506 are fixedly connected to the upper interior of the paint spray box 1 and the grid plate 501, respectively. The outer wall of the threaded rod 504 is rotatably connected to a moving block 505 by a thread. The outer wall of the limiting rod 506 is slidably connected to a sliding block 507. One end of the moving block 505 and the sliding block 507 are fixedly connected to the lower part of the outer wall of the placement plate 502, and the other end of the moving block 505 and the sliding block 507 are in contact with one side of the inner wall of the paint spray box 1. The other side of the lower end face of the grid plate 501 is fixedly connected to a servo motor 513, and the output end of the servo motor 513 is fixedly connected to the threaded rod 504. A sealing box 514 is provided around the servo motor 513, and the sealing box 514 is fixedly connected to the grid plate 501. The servo motor 513 drives the threaded rod 504 to rotate, thereby driving the moving block 505, the placement plate 502 and the support bar 503 to achieve automatic lifting and lowering. Workers only need to place or remove the board when the placement plate 502 is raised and lowered to the connection port 2, without having to manually carry the board in and out of the paint spray box 1, thus reducing labor intensity.

[0022] The moving block 505 moves against the inner wall of the paint spraying box 1, and the sliding block 507 slides on the limiting rod 506, providing a stable guiding structure for the lifting and lowering of the placement plate 502. This design effectively prevents the placement plate 502 from shifting or shaking during the lifting and lowering process, ensuring that the plate remains stable during the spraying process, thereby ensuring that the paint can be accurately and evenly sprayed on the surface of the plate, improving spraying accuracy and product qualification rate.

[0023] A connecting pipe 512 is fixedly inserted into the upper end of the feed pump 509, and the upper end of the connecting pipe 512 passes through the grid plate 501 and is fixedly connected to the spray paint strip 508. A connected feed pipe 3 is fixedly connected to one side of the outer wall of the spray paint box 1, and a connected discharge pipe 4 is fixedly connected to one side of the lower end face of the spray paint box 1. As the placement plate 502 moves the board upward, the spray paint strip 508 continuously and evenly sprays paint. The movement of the board and the paint spraying are synchronized, so that the paint can evenly cover the surface of the board and avoid problems such as excessively thick or thin paint in some areas or missed spraying. This spraying method effectively improves the uniformity and consistency of the paint spraying, ensures the stable quality of the coating on the surface of the board, and meets high standards of appearance and protection requirements.

[0024] Working principle: The worker pours paint into the lower part of the paint spraying box 1 through the feed pipe 3. When it is necessary to spray paint the board, the servo motor 513 is started. The servo motor 513 drives the output end to rotate, which drives the threaded rod 504 to rotate. The rotation of the threaded rod 504 drives the moving block 505, which is attached to the inner wall of the paint spraying box 1, to move upward. The movement of the moving block 505 drives the placement plate 502 and the support bar 503 to move upward. The movement of the placement plate 502 drives the sliding block 507 to move on the limit rod 506 until the placement plate 502 moves out of the communication port 2.

[0025] The worker places the board to be painted onto the support bar 503 on the placement plate 502, starts the servo motor 513, and the output end of the servo motor 513 moves in the opposite direction. The placement plate 502, support bar 503, and board enter the paint spraying box 1. The worker starts the feed pump 509, and the paint pump 509 delivers paint through the counterweight head 511 and the extraction pipe 510 into the connecting pipe 512. The connecting pipe 512 delivers the paint into the spray bar 508, and the spray bar 508 sprays paint evenly. The servo motor 513 is started again, and the placement plate 502 and support bar 503 move upward, causing the board to move upward. The spray bar 508 sprays paint onto the upward-moving board. As the board moves upward, the paint is evenly sprayed onto the surface of the board until the board moves out of the connecting port 2 and the surface of the board is evenly covered with paint. The worker then removes the board. During the paint spraying process, the splashed paint falls and passes through the grid plate 501 into the lower part of the paint spraying box 1, thus achieving recycling and reducing waste.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
