[0002] Paint filling is a crucial step in the paint production process, involving multiple steps such as paint storage, transportation, metering, and filling. During the filling process, the paint temperature has a significant impact on its fluidity and filling effect. Heating the paint reduces its viscosity and improves its fluidity, thus facilitating filling and subsequent use. Therefore, to ensure the quality and efficiency of paint filling, preheating treatment of the paint is necessary.
[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: Before the paint is filled, the paint is usually preheated by direct heating with heating wire or water bath heating. During heating, the paint is in a static state, and the paint in the center of the paint tank cannot be heated well, resulting in different temperatures on the inner and outer cams. The paint is not heated evenly, which affects the preheating effect. Utility Model Content

[0005] This application provides a paint preheating device for paint filling, including a heating tank, inside which a paint tank is disposed. A water inlet pipe is disposed at the top of the heating tank, and a water outlet pipe is disposed on one side of the bottom of the heating tank. A stirring mechanism is disposed inside both the heating tank and the paint tank. The stirring mechanism includes: a rotating shaft rotatably connected to the interior of the heating tank and the paint tank; a drive motor fixedly installed at the top of the heating tank, with the output shaft of the drive motor fixedly connected to the rotating shaft; multiple stirring rods fixedly disposed at the bottom of the rotating shaft, with the bottommost stirring rod contacting the inner wall of the bottom of the paint tank; and an outer stirring assembly disposed inside the heating tank, which is used to stir the hot water inside the heating tank.
[0006] Furthermore, the outer stirring assembly includes: a fixed plate, fixedly mounted on the rotating shaft inside the heating tank; two vertical rods, respectively fixedly mounted at the bottom of both ends of the fixed plate; and multiple extension rods, fixedly mounted on both sides of the vertical rods, with the multiple extension rods arranged parallel to each other at equal intervals on the outer side of the vertical rods.
[0007] Furthermore, a feed pipe is fixedly installed on one side of the bottom of the paint tank, and a discharge pipe is fixedly installed at the bottom of the paint tank. Both the feed pipe and the discharge pipe extend out of the heating tank, and the vertical rod and multiple extension rods are installed at the top of the feed pipe.
[0008] Furthermore, a scraping assembly is provided on the outer side of the rotating shaft extending into the paint tank. The scraping assembly includes: multiple movable sleeves fixedly disposed in the middle of the rotating shaft, and the multiple movable sleeves are arranged parallel to each other at equal intervals on the outer side of the rotating shaft; an extension rod inserted and connected to the outer side of the movable sleeves; a convex plate fixedly disposed at one end of the multiple extension rods on one side; and a concave plate fixedly disposed at one end of the multiple extension rods on the other side, and both the convex plate and the concave plate are in contact with the inner wall of the paint tank.
[0009] Furthermore, one end of the movable sleeve is provided with a movable groove, the extension rod is slidably connected to the inside of the movable groove, and a spring is provided inside the movable groove, with the two ends of the spring being fixedly connected to the inner wall of the movable groove and the extension rod, respectively.

Detailed Implementation
[0016] This application discloses a paint preheating device for paint filling. The rotation of the rotating shaft 51 causes the stirring rod 53, movable sleeve 541 and extension rod 542 inside the paint tank 20 to rotate, stirring the paint inside the paint tank 20. The elastic force of the spring 543 drives the convex plate 544 and concave plate 545 to stick tightly to the inner wall of the paint tank 20. Together with the stirring rod 53 at the bottom, the paint adhering to the inner wall of the paint tank 20 is scraped off. The rotation of the vertical rod 552 and the extension rod 553 drives the flow of water on the outside of the paint tank 20, so that the water is heated evenly and the preheating effect is improved.
[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0018] Please refer to Figure 1 and Figure 2 This embodiment provides a paint preheating device for paint filling, including a heating tank 10, a paint tank 20 disposed inside the heating tank 10, a water inlet pipe 60 disposed at the top of the heating tank 10, and a water outlet pipe 70 disposed on one side of the bottom of the heating tank 10. A stirring mechanism 50 is disposed inside the heating tank 10 and the paint tank 20. The stirring mechanism 50 includes a rotating shaft 51, a drive motor 52, a stirring rod 53, a scraping assembly 54, and an outer stirring assembly 55. The rotating shaft 51 is rotatably connected to the interior of the heating tank 10 and the paint tank 20. The drive motor 52 is fixedly installed on the top of the heating tank 10, and the output shaft of the drive motor 52 is connected to the rotating shaft. A fixed connection is established at the bottom of the rotating shaft 51, with multiple stirring rods 53 fixedly mounted on the bottom. The bottommost stirring rod 53 is in contact with the inner wall of the bottom of the paint tank 20. The water inside the heating tank 10 is heated by the resistance wire inside the heating tank 10, and the paint inside the paint tank 20 is preheated by the hot water, which reduces the viscosity of the paint, improves its fluidity, and facilitates paint filling and subsequent use. The output shaft of the drive motor 52 drives the rotating shaft 51 to rotate, which in turn drives the multiple stirring rods 53 to rotate, stirring the paint inside the paint tank 20. This ensures that the paint inside the paint tank 20 is heated evenly, thereby improving the preheating effect.
[0019] Please refer to Figure 1 , Figure 2 and Figure 3A scraping assembly 54 is provided on the outer side of the rotating shaft 51, which extends into the paint tank 20. The scraping assembly 54 includes a movable sleeve 541, an extension rod 542, a spring 543, and a convex plate 544. Multiple movable sleeves 541 are fixedly disposed in the middle of the rotating shaft 51 and are arranged parallel to each other at equal intervals on the outer side of the rotating shaft 51. One end of each movable sleeve 541 has a movable groove. The extension rod 542 is slidably connected to the inside of the movable groove. The spring 543 is disposed inside the movable groove, and its two ends are fixedly connected to the inner wall of the movable groove and the extension rod 542, respectively. The convex plate 544 is fixedly disposed at one end of one of the multiple extension rods 542 on one side, and the concave plate 545 is fixedly disposed at one end of the multiple extension rods 542 on the other side. Both the convex plate 544 and the concave plate 545 are in contact with the inner wall of the paint tank 20. The elastic force of the spring 543 in the movable groove can drive the extension rod 542 to move towards the inner wall of the paint tank 20, so that the convex plate 544 and the concave plate 545 at one end of the extension rod 542 are in close contact with the inner wall of the paint tank 20. The protrusion in the middle of the convex plate 544 and the protrusions on both sides of the concave plate 545 scrape the inner wall of the paint tank 20 to prevent the paint from adhering to the inner wall of the paint tank 20, thereby affecting the preheating effect of the paint inside the paint tank 20. The movable sleeve 541 and the extension rod 542 can also stir the paint inside the paint tank 20 with the rotation of the rotating shaft 51, improve the fluidity of the paint, and make the paint heat evenly inside the paint tank 20.
[0020] Please refer to Figure 1 , Figure 2 and Figure 3 An outer stirring assembly 55 is disposed inside the heating tank 10 and is used to stir the hot water inside the heating tank 10. The outer stirring assembly 55 includes a fixing plate 551, vertical rods 552, and extension rods 553. The fixing plate 551 is fixedly disposed on the rotating shaft 51 inside the heating tank 10. Two vertical rods 552 are respectively fixedly disposed at the bottom ends of the fixing plate 551. Multiple extension rods 553 are fixedly disposed on both sides of the vertical rods 552, and the multiple extension rods 553 are arranged parallel to each other at equal intervals on the outside of the vertical rods 552. A feed pipe 30 is fixedly disposed on one side of the bottom of the paint tank 20, and a discharge pipe 4 is fixedly disposed on the bottom of the paint tank 20. Both the feed pipe 30 and the discharge pipe 40 extend out of the heating tank 10. The vertical rod 552 and multiple extension rods 553 are located at the top of the feed pipe 30. When the vertical rod 552 and extension rods 553 rotate, they will not contact the feed pipe 30 and will not affect the normal input of the paint. The rotation of the rotating shaft 51 drives the fixing plate 551 inside the heating tank 10 to drive the vertical rod 552 and multiple extension rods 553 to rotate around the paint tank 20. This allows the vertical rod 552 and extension rods 553 to stir the hot water inside the heating tank 10, improve the fluidity of the water flow, and prevent uneven heating of the resistance wire inside the water heating tank 10, which would affect the preheating effect inside the paint tank 20.
[0021] The functional principle of this application can be explained through the following methods:
[0022] In use, the drive motor 52 at the top of the heating tank 10 is started, causing the output shaft of the drive motor 52 to drive the drive motors 52 inside the heating tank 10 and the paint tank 20 to rotate. The resistance wire inside the heating tank 10 heats the water. The drive motor 52 drives the fixed plate 551 to rotate, causing the vertical rod 552 and multiple extension rods 553 at the bottom of the fixed plate 551 to rotate around the paint tank 20, improving the fluidity of the water flow and making the water flow more evenly heated. The rotating shaft 51 drives the stirring rod 53, the movable sleeve 541, and the extension rod 542 inside the paint tank 20 to rotate, thereby stirring the paint. The coating inside the material tank 20 is stirred to improve its fluidity, allowing it to be heated evenly. The spring 543 inside the movable groove of the movable sleeve 541 causes the extension rod 542 to tend to move towards the inner wall of the coating tank 20. This allows the extension rod 542 to bring the convex plate 544 and concave plate 545 into close contact with the inner wall of the coating tank 20. The protruding part in the middle of the convex plate 544 and the protruding parts on both sides of the concave plate 545 scrape the inner wall of the coating tank 20, preventing the coating from adhering to the inner wall of the coating tank 20. This results in more even heating of the coating inside the coating tank 20 and improves the preheating effect.
