[0026] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 5 As shown, a water-based paint concentration regulating device includes a loading component 1 which can make the device run stably and can accelerate the speed at which the finished paint product flows out of the device. A stirring tank 2 which can accommodate the paint to be stirred and mixed is arranged in the loading component 1, and a stirring component 3 which can contact the paint at multiple points to stir it and prevent the paint from continuously adhering to the inner wall of the stirring tank 2 is arranged on the stirring tank 2.

[0028] In this embodiment: the loading assembly 1 includes a frame 101, a frame 102 is movably installed in the frame 101, a hydraulic rod 103 is arranged between the frame 101 and the frame 102, and a limit clamp 104 is fixedly installed in the frame 102; the frame 101 is rotatably connected to the frame 102, and the frame 101 and the frame 102 are rotatably connected to the hydraulic rod 103; the frame 102 on which the stirring tank 2 is installed is installed through the frame 101, and the frame 102 can be rotated a certain angle in the device with the connection between the frame 101 and the frame 102 as the center, and the frame 102 is driven to rotate relative to the frame 101 by the hydraulic rod 103, so that the stirring tank 2 can be properly tilted during unloading so that the paint can flow out quickly, and the limit clamp 104 further limits the movable range of the stirring tank 2 on the frame 102, thereby improving the stability of the stirring tank 2.

[0029] In this embodiment: the stirring tank 2 includes a main tank body 201 fixedly installed in the frame 102, a sub-tank body 202 is fixedly connected above the main tank body 201, a feed valve 203 is fixedly connected to the feed end of the main tank body 201, and a discharge valve 204 is fixedly connected to the discharge end of the main tank body 201; the sub-tank body 202 cooperates with the main tank body 201 to form a complete tank body to accommodate paint, and the setting of the sub-tank body 202 can facilitate the installation of some parts of the stirring assembly 3 into the main tank body 201, and the feed valve 203 is used to control the opening and closing of the channel for the paint to enter the stirring tank 2, and the discharge valve 204 is used to control the opening and closing of the channel for the paint to flow out of the stirring tank 2.

[0030] In this embodiment: the stirring assembly 3 includes a stirring member that can stir the paint in the stirring tank 2, a driving member that can make the stirring member rotate at a certain speed, and a scraping member that can stir the paint at a position different from the stirring member and gradually scrape off the paint adhering to the inner wall of the stirring tank 2. The driving member includes a shaft seat 301 fixedly connected to the stirring tank 2, a rotating shaft 302 is arranged along the axis line in the shaft seat 301, and a motor 303 is fixedly connected to the upper end of the rotating shaft 302. The stirring member includes a stirring rod 304 fixedly connected to the lower end of the rotating shaft 302, and a stirring paddle 305 is fixedly connected to the lower end of the stirring rod 304. The scraping member includes a U-shaped frame 306 movably connected to the stirring rod 304, a connecting rod 307 is movably connected to one side of the U-shaped frame 306, and a spring 308 is movably connected to the outer side of the connecting rod 307. A limiting ring 309 is fixedly connected to one end of the connecting rod 307, and an arc scraper 310 is arranged between the stirring paddle 305 and the connecting rod 307.

[0031] The shaft seat 301 is rotatably connected to the rotating shaft 302, the stirring rod 304 is rotatably connected to the U-shaped frame 306, the U-shaped frame 306 is slidably connected to the connecting rod 307, and the stirring paddle 305 and the connecting rod 307 are both rotatably connected to the arc scraper 310;

[0032] The shaft seat 301 is used to seal the upper opening of the auxiliary tank body 202, and the movable range of the rotating shaft 302 in the device is limited. The rotating shaft 302 is driven to rotate relative to the shaft seat 301 by the motor 303, and the rotation of the rotating shaft 302 is transmitted to the stirring paddle 305 and the U-shaped frame 306 by the stirring rod 304. The arc scraper 310 is driven to rotate by the stirring paddle 305, and the position of the lower end of the arc scraper 310 in the main tank body 201 is limited. The connecting rod 307 connected to the U-shaped frame 306 is used to improve the stability of the arc scraper 310 rotating with the stirring paddle 305. The connecting rod 307, which can slide relative to the U-shaped frame 306, can make the arc scraper 310 rotate relative to the stirring paddle 305, and prevent the spring 308 from falling off the connecting rod 307 through the limiting ring 309. The movable range of the connecting rod 307 relative to the U-shaped frame 306 is limited by the spring 308. The stirring assembly 3 is in contact with the paint with a larger area through the arc scraper 310, and the arc scraper 310 after contacting the inner wall of the main tank body 201 can stir the paint when rotating with the stirring paddle 305, and scrape off the paint adhering to the inner wall of the main tank body 201.

[0033] Working principle: When the device is installed and used for concentration adjustment of water-based paint production, it is connected to the quantitative injection device through the feed valve 203 and connected to the paint outlet device through the discharge valve 204. When the paint is injected into the main tank 201 after the feed valve 203 is opened, the motor 303 can be driven to drive the rotating shaft 302 to rotate at a certain speed;

[0034] During the rotation of the rotating shaft 302, after its rotation is transmitted to the stirring paddle 305 through the stirring rod 304, the stirring paddle 305 will continue to rotate to stir the paint, and the arc scraper 310 driven by other components to rotate will be subjected to the centrifugal force, so that the arc scraper 310 rotating around the axis of the rotating shaft 302 can gradually approach the inner wall of the main tank 201 and pull the connecting rod 307 until the spring 308 is compressed to the extent that the force on the connecting rod 307 is balanced;

[0035] Therefore, the position of the arc scraper 310 in the main tank body 201 can be changed by adjusting the rotation speed of the rotating shaft 302, so that it can stir the paint at a certain distance relative to the inner wall of the main tank body 201, or stir the paint after contacting the inner wall of the main tank body 201 and scrape off the paint adhering to the inner wall of the main tank body 201. In this way, on the basis of continuous stirring of the paint by the stirring paddle 305, the paint in the stirring tank 2 can be evenly mixed in a short time and the concentration can be consistent everywhere through the rotation of the arc scraper 310 with variable position.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
