Description
Technical Field
[0001] The utility model relates to the technical field of paint processing, in particular to a paint mixing tank. Background Art
[0002] A paint mixing tank is a device used to mix and stir chemicals such as coatings, paints, resins, adhesives, etc. It usually consists of a sealed container and an agitator, and the mixing and stirring process can be achieved by an electric motor or manual operation.
[0003] Since paint has a certain viscosity, during the mixing process, the residual paint will adhere to the tank body and the agitator. Therefore, the paint mixing tank is relatively difficult to clean in the subsequent process, and it takes a certain amount of time and effort to clean it thoroughly. At the same time, the residual paint will also be discarded during the cleaning process, which will cause waste. There are also some paint mixing tanks with built-in scraper cleaning function on the market, but the scraper and stirring blade are integrated. Although they can complete the mixing and scraping functions, long-term continuous friction can easily cause wear of the tank body and the scraper, which will not only reduce the service life of the tank body, but also cause incomplete scraping after a certain period of use, thereby affecting the cleaning efficiency.
[0004] Therefore, it is urgent to provide a paint mixing tank to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is that during the stirring process, the residual paint will adhere to the tank body and the agitator. Therefore, the paint mixing tank is relatively difficult to clean in the subsequent cleaning process, and it takes a certain amount of time and effort to clean it thoroughly. At the same time, the residual paint will also be discarded in the cleaning process, which will cause waste. There are also some paint mixing tanks with built-in scraper cleaning function on the market, but the scraper and stirring blade are integrated. Although they can complete the stirring and scraping functions, long-term continuous friction can easily cause wear of the tank body and the scraper, which will not only reduce the service life of the tank body, but also cause incomplete scraping after a certain period of use, thereby affecting the cleaning efficiency.

[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0037] See also Figure 1-Figure 7 A paint mixing tank comprises a mixing tank shell 1, a support frame 2 is fixedly connected to the outer wall of the mixing tank shell 1, a tank cover 3 is fixedly connected to the top of the mixing tank shell 1, an arc groove 4 is opened at the center of the top of the tank cover 3, and a connecting block 5 is fixedly connected to one side of the top of the tank cover 3;
[0038] like Figure 1 As shown, two symmetrically distributed feed pipes 6 are fixedly connected to the outer wall of the mixing tank shell 1 near the top, and one end of the two feed pipes 6 is provided with an external thread. The thread allows the paint pipe connected to the feed pipe 6 to be connected by a threaded connection, so that the feeding process is more stable;
[0039] like Figure 6 or Figure 7As shown, a pressing mechanism 7 is provided on one side of the top of the tank cover 3, and the pressing mechanism 7 includes a track groove 701 fixedly connected to one side of the top of the tank cover 3, and a first limiting column 702 is also fixedly connected between the track groove 701 and the tank cover 3, and a reset spring 703 is sleeved on the outer wall of the first limiting column 702, and a moving block 704 is sleeved on the outer wall of the first limiting column 702, and second limiting columns 705 are fixedly connected on both sides of the moving block 704, and a connecting rod 706 is fixedly connected to the bottom of the moving block 704, and a pushing block 707 is fixedly connected to the bottom of the connecting rod 706, and limiting grooves matching the two second limiting columns 705 are respectively opened on both sides of the inner wall of the track groove 701, and positioning holes matching the first limiting columns 702 are opened on the moving block 704, and the limiting grooves opened on both sides of the inner wall of the track groove 701 can limit The second limiting column 705 moves along the trajectory to prevent the moving block 704 from leaving the track groove 701 during the movement. The positioning hole on the top of the moving block 704 plays a positioning role. By pulling down the moving block 704, the moving block 704 moves downward along the first limiting column 702. During the downward movement, the connecting rod 706 fixedly connected to the moving block 704 moves downward with the moving block 704. At this time, the pushing block 707 fixedly connected to the connecting rod 706 enters the mixing tank shell 1 and contacts the inner wall of the mixing tank shell 1. During the downward movement of the pushing block 707, the residual paint on the inner wall will be pushed to the bottom of the mixing tank shell 1. When the pushing block 707 reaches the bottom, the moving block 704 is released, and the moving block 704 returns to the initial position under the action of the reset spring 703.
[0040] like Figure 4 As shown, a scraper mechanism 8 is rotatably connected in the mixing tank shell 1, and the scraper mechanism 8 includes a first rotating sleeve 801 fixedly connected to the center position of the bottom of the tank cover 3, and a second rotating sleeve 803 fixedly connected to the center position of the inner surface of the bottom of the mixing tank shell 1. A scraper 802 is fixedly connected between the first rotating sleeve 801 and the second rotating sleeve 803, and a rotating handle that penetrates the arc groove 4 is also fixedly connected to one side of the top of the scraper 802. After the discharge is completed, a small amount of paint will remain on the inner wall of the mixing tank shell 1. At this time, the scraper 802 needs to be rotated to scrape the remaining paint on the inner wall of the mixing tank shell 1 to one side, and then the remaining paint on the inner wall is pushed into the trapezoidal groove 10 under the action of the pressing mechanism 7. The rotating handle is provided to manually scrape off the residual paint on the inner wall of the mixing tank shell 1, thereby reducing the wear on the inner wall of the mixing tank shell 1 and increasing the service life of the tank body and the scraper.

[0045] When the utility model is in use, the paint tube is connected to the feed tube 6, and the paint is injected into the stirring tank shell 1. When the paint fills the inside of the stirring tank shell 1, the injection of the paint is stopped, and the stepper motor 13 is turned on. After the stepper motor 13 is started, the output shaft of the stepper motor 13 drives the rotating shaft 901 to rotate, thereby driving the stirring blade 902 on the outer wall of the rotating shaft 901 to stir the paint entering the stirring tank shell 1. After stirring, the stepper motor 13 is turned off, and the valve on the discharge pipe 11 is opened to discharge the mixed paint. After the discharge is completed, a small amount of paint will remain on the inner wall of the stirring tank shell 1. At this time, it is necessary to rotate the rotating handle on the top of the scraper 802 to remove the paint remaining on the inner wall of the stirring tank shell 1. The paint is scraped to one side, and then the moving block 704 is pulled down to move the moving block 704 downward along the first limit column 702. During the downward movement, the connecting rod 706 fixedly connected to the moving block 704 moves downward with the moving block 704. At this time, the pushing block 707 fixedly connected to the connecting rod 706 enters the mixing tank shell 1 and contacts the inner wall of the mixing tank shell 1. During the downward movement of the pushing block 707, the residual paint on the inner wall will be pushed into the trapezoidal groove 10. When the pushing block 707 reaches the bottom, the moving block 704 is released, and the moving block 704 returns to the initial position under the action of the reset spring 703. At this time, the residual paint in the tank will be discharged from the discharge pipe 11 along the trapezoidal groove 10.
