[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] See Figures 1-4A feeding device for spray coating includes a main component 1, which includes: a storage tank 11 with a pipe 12 at its bottom; a conveying pipe 13 at the bottom end of the pipe 12; and a spray gun 14 mounted on the output end of the conveying pipe 13 via a pump body. A cleaning component 2 is provided on the storage tank 11, the pipe 12, and the conveying pipe 13. The cleaning component 2 includes: a rotating shaft 21 passing through and rotatably connected to the storage tank 11; a bracket 22 fixedly connected to the top of the rotating shaft 21; and a motor 23. The storage tank 11 is mounted on the support 22, and the output shaft of the motor 23 is fixedly connected to the top of the rotating shaft 21. A connecting rod 24 is symmetrically and fixedly connected to the outer wall of the rotating shaft 21. A first cleaning plate 25 is fixedly connected to the end of the connecting rod 24 away from the rotating shaft 21, and the first cleaning plate 25 is slidably connected to the inner wall of the storage tank 11. A second cleaning plate 26 is symmetrically and fixedly connected to the outer wall of the rotating shaft 21, and the second cleaning plate 26 is slidably connected to the inner wall of the pipe 12. A discharge mechanism 27 is mounted on the conveying pipe 13. The discharge mechanism 27 includes: a first solenoid valve 271, mounted on the conveying pipe 13; a vertical pipe 272, which is connected through to the bottom of the conveying pipe 13 and is located below the pipe 12; and a second solenoid valve 273, mounted on the vertical pipe 272. The connection between the storage tank 11 and the pipe 12 is an inclined plane.

[0041] During use, the pump body pumps the paint placed inside the storage tank 11 through the pipe 12 and delivery pipe 13 to the spray gun 14, where the spray gun 14 sprays the paint onto the object. After spraying, the operator adds cleaning fluid to the storage tank 11 and starts the motor 23. The motor 23 drives the rotating shaft 21 to rotate. The cleaning plate 25, connected to the rotating shaft 21 by the connecting rod 24, slides on the inner wall of the storage tank 11, while the cleaning plate 26 slides on the inner wall of the pipe 12. The cleaning plates 25 and 26 work together to scrape off the paint adhering to the inner walls of the storage tank 11 and the pipe 12. The storage tank 11 and pipe 12 come into timely contact with the cleaning solution. After cleaning by cleaning plates 25 and 26 for a period of time, the wastewater is discharged through the discharge mechanism 27. When the spray gun 14 is spraying, solenoid valve 271 is open and solenoid valve 273 is closed. Before pouring in the cleaning solution, the operator controls solenoid valve 271 to be closed. After cleaning by cleaning plates 25 and 26, the operator controls solenoid valve 273 to be opened, and the wastewater inside the storage tank 11 and pipe 12 is discharged through the vertical pipe 272 for easy cleaning in the next cycle. The inclined surface of the storage tank 11 facilitates the discharge of paint during use, reducing paint residue on the storage tank 11 and thus reducing the pressure of subsequent cleaning.

[0042] The aforementioned solenoid valve 271 and solenoid valve 273 are equipped with an external power supply. When energized, the electromagnetic coils on solenoid valve 271 and solenoid valve 273 generate electromagnetic force to lift the closing element from the valve seat, thus opening the valve. When de-energized, the electromagnetic force disappears, and the spring force presses the closing element onto the valve seat, thus closing the valve, thereby realizing the control of fluid flow.

[0043] Example 2

[0044] An auxiliary function has been added based on Embodiment 1.

[0045] See Figures 1-4 A scraper 3 is symmetrically and fixedly connected to the cleaning plate 25 and the rotating shaft 21, and the scraper 3 is slidably connected to the inner top surface of the storage tank 11. An inclined surface is provided at one end of the cleaning plate 25 near the inner wall of the storage tank 11. A heating layer 4 is provided outside the storage tank 11 and the pipe 12.

[0046] As the rotating shaft 21 rotates, the scraper 3 connected between the rotating shaft 21 and the cleaning plate 25 cleans the inner top surface of the storage tank 11, avoiding any blind spots and thus enhancing the cleaning effect. The inclined cleaning plate 25 contacts the inner wall of the storage tank 11 on one side as it rotates. The inclined surface increases the scraping force against substances adhering to the inner wall of the storage tank 11, allowing for more effective removal of stubborn stains or thick layers of residual paint, resulting in better cleaning. The heating layer 4 outside the storage tank 11 and pipe 12 includes heating elements and an insulation layer. The heating elements, such as heating wires or heating plates, contact the outer walls of the storage tank 11 and pipe 12. The insulation layer is installed outside the heating elements. The heating layer 4 heats the cleaning fluid, making the paint easier to soften and dissolve during cleaning, thus improving the cleaning effect.

[0047] The embodiments of the present invention have been shown and described. It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
