[0009] This utility model discloses a painting device for processing wooden handicrafts, which has the following advantages: A worktable is rotatably mounted on a support frame. When painting wooden handicrafts, the handicrafts are placed on the worktable, and the spray nozzles at the ends of the spray bars on both sides and top of the gantry frame facing the worktable spray the handicrafts. The spray nozzles on both sides and top of the handicrafts spray simultaneously, increasing the efficiency of the painting process. Simultaneously, a third motor drives the worktable to rotate on the support frame, causing the wooden handicrafts to rotate as well. Multiple spray nozzles spray the handicrafts from multiple angles, achieving uniform painting and reducing missed areas due to spray angle issues. For painting the interior of hollow or complex wooden handicrafts, a first motor drives the mounting platform to slide on a first slide rail, causing a second slide rail to move vertically. A second motor drives the spray bar to extend the spray nozzles to the hollow areas inside the wooden handicrafts. This spray painting device is suitable for painting various types of wooden handicrafts, especially those with openwork interiors. It offers higher efficiency and more even coating compared to manual painting, while preventing harm to workers from volatile organic compounds in the paint. Multiple nozzles are mounted at the end of the spray bar, angled upwards, horizontally, and downwards. Magnetic valves connected to branch pipes allow the device to control the opening and closing of these nozzles based on the structure of the wooden handicraft. This enables simultaneous painting of the top and bottom of the openwork interiors, further increasing efficiency and the range of areas that can be painted. It also provides good coating results for complex surfaces that are difficult to reach with horizontal spraying, making it suitable for wooden handicrafts with various openwork and complex surface structures.

[0013] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a spray painting device for processing wooden handicrafts.
[0014] like Figure 1-2 As shown, this utility model discloses a painting device for processing wooden handicrafts, including a support frame 1; a workbench 2 is provided on the upper side of the support frame 1; gantry frames 3 are provided on both sides of the workbench 2; a first slide rail 4 is provided on the uprights on both sides and the top crossbeam of the gantry frame 3 relative to the workbench 2; a mounting platform 5 is slidably provided on the first slide rail 4; a first motor 6 is fixedly provided at one end of the first slide rail 4 to drive the mounting platform 5 to slide on the first slide rail 4; a second slide rail 7 is fixedly provided on the mounting platform 5 facing the workbench 2; a spray bar 8 is slidably provided on the second slide rail 7; a second motor 9 is provided at one end of the second slide rail 7 to drive the spray bar 8 to slide on the second slide rail 7; a spray head 10 is provided at the end of the spray bar 8 facing the workbench 2; a paint conveying pipe 11 is provided on the upper side of the spray bar 8; and a branch pipe 12 is provided on the spray head 10 to communicate with the paint conveying pipe 11.
[0015] Combination Figure 1-2 As shown, when painting the interior of hollow or complex wooden handicrafts, the first motor 6 drives the mounting platform 5 to slide on the first slide rail 4, which in turn moves the second slide rail 7 vertically. The second motor 9 drives the spray bar 8 to extend the spray nozzle 10 to the hollowed-out area inside the wooden handicraft, thus painting the hollowed-out area. This avoids the difficulty of external painting in reaching the hollowed-out area inside the wooden handicraft, making this painting device more suitable for painting different wooden handicrafts.
