[0002] Wood products are mainly divided into the following categories: furniture wood products, office wood products, handicraft wood products, gardening wood products, and daily wood products. After wood is made into various wooden boards, it needs to be painted. After the paint is applied, it needs to be sent to a paint drying room to dry the paint. Usually, manual control of the spray head is required for painting, resulting in a relatively high labor intensity, low work efficiency, and uneven painting caused by manual painting, which affects the quality of the finished product. Currently, there is no reliable technical solution. Content of the Utility Model

[0020] Example: Refer to Figures 1-4 A sheet painting device as shown, including a main housing 1. Coaxial feed inlets 2 and discharge outlets 3 are respectively arranged at opposite ends of the main housing 1. Conveying rollers 10 for guiding and conveying the sheet 11 are installed at the bottom ends of the inner cavities of the feed inlet 2 and the discharge outlet 3. A painting chamber 4 is arranged at the center inside the main housing 1. The painting chamber 4 is communicated with the feed inlet 2 and the discharge outlet 3. Inside the painting chamber 4, a painting pipe 5, a coating roller group 6, and an air spraying pipe 7 are fixedly installed in sequence along the conveying direction of the sheet 11 to paint, coat, and dry the sheet in sequence;

[0021] The number of the painting pipes 5 is two and they are communicated through pipes. The two painting pipes 5 are symmetrically distributed outside the upper and lower ends of the sheet 11. The number of the coating roller groups 6 is two. The two coating roller groups 6 are symmetrically distributed outside the upper and lower ends of the sheet 11, and the coating rollers of the coating roller group 6 are in contact with the outer wall of the sheet 11 to scrape off the excess paint on the upper and lower end faces after painting the sheet, and at the same time ensure the uniform distribution of the surface paint to avoid painting dead angles. The number of the air spraying pipes 7 is two and they are communicated through pipes. The two air spraying pipes 7 are symmetrically distributed outside the upper and lower ends of the sheet 11 to dry the upper and lower ends of the sheet 11.

[0022] Through the above technical solution of the present invention, a paint tank 8 is fixedly installed at the top end of the main housing 1. A first pump body 9 with an input end leading into the paint tank 8 is fixedly installed at the top of the inner cavity of the main housing 1. The output end of the first pump body 9 is communicated with the painting pipe 5 to supply paint to the painting pipe 5.

[0023] Through the above technical solution of the present utility model, a hot air box 12 is fixedly installed on one side of the main machine case 1. An electric heating pipe 16 and a fan 17 are fixedly installed inside the hot air box 12. The fan 17 is located between the electric heating pipe 16 and the air inlet in the hot air box 12. The fan 17 sends the heat generated by the electric heating pipe 16 to the spray air pipe to be sprayed out, thereby drying the board.

[0024] Through the above technical solution of the present utility model, a filter plate 18 is fixedly installed at the air inlet of the hot air box 12 to facilitate filtering dust in the air and ensure the quality of painting.

[0025] Through the above technical solution of the present utility model, a retaining table 13 is fixedly installed inside the main machine case 1 below the board 11. A paint collection area 14 is provided below the retaining table 13. A second pump body 15 is fixedly installed inside the paint collection area 14. The output end of the second pump body 15 is communicated with the paint tank 8 through a pipeline. The paint scraped off the board 11 by the coating roller group 6 enters the paint collection area 14 under the guidance of the retaining table 13 and is pumped back into the paint tank 8 by the second pump body 15 for reuse.

[0026] The working principle of this utility model:

[0027] The motor drives the conveying roller 10 to rotate, and the board 11 is fed into the inside of the main machine case 1 from the feed port 2. The conveying roller 10 inputs the board 11. The first pump body 9 extracts the paint inside the paint tank 8 and sends it into the inside of the spray paint pipe 5. After the board 11 is fed from the feed port 2, it is first sprayed by the upper and lower groups of spray paint pipes 5, and both the upper and lower surfaces are evenly sprayed. Then it is coated on the surface by the coating roller group 6 driven by the motor to rotate. The coating roller group 6 has two groups and can reliably coat the upper and lower ends of the board 11, evenly coat the paint, and at the same time scrape off the excess paint. The scraped paint enters the paint collection area 14 under the guidance of the retaining table 13 and is pumped back into the paint tank 8 by the second pump body 15 for reuse. After the paint coating on the board is completed, it is conveyed to the drying area. The hot air box 12 sends hot air into the spray air pipe 7. The upper and lower groups of spray air pipes 7 will evenly dry the upper and lower surfaces of the board, and then it is conveyed out from the discharge port 3, and the spray painting operation of the board 11 can be completed. The efficiency is high and no manual operation is required.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
