[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A paint mixing device for preparing epoxy paint includes a paint mixing tank 1 and a sealing cover 2 that can be detachably installed above the paint mixing tank 1. A paint discharge port 4 is provided at the bottom of the paint mixing tank 1, and an evenly distributed chute 3 is opened in a ring shape on the inner surface. A mounting ring 5 is slidably connected to the inside of the chute 3. An evenly distributed float 6 is embedded and connected to the outer surface of the mounting ring 5 near the chute 3, and a scraper assembly is provided between the outer side and the inner wall of the paint mixing tank 1 for cleaning the residual epoxy paint on the inner wall of the paint mixing tank 1. A servo motor is installed on the top of the sealing cover 2, and the output end of the servo motor is connected to the stirring shaft 7. One end of the stirring shaft 7 passes through the sealing cover 2 and extends to the outside of the sealing cover 2. A first stirring plate 8 and a second stirring plate 9 for stirring and mixing are sequentially installed on the outside of the stirring shaft 7.

[0020] When mixing paint, first add paint and curing agent into the paint mixing tank 1, seal the paint mixing tank 1 through the sealing cover 2, and then start the servo motor to drive the first stirring plate 8 and the second stirring plate 9 to rotate for stirring and mixing. After stirring, open the paint discharge port 4 to discharge the mixed paint. When discharging the paint, as the paint liquid level drops, the mounting ring 5 is always above the liquid level of the paint due to the floating effect of the float 6, and when the paint liquid level drops, the mounting ring 5 is driven to move downward, thereby driving the scraper assembly to move. The scraper assembly can be used to scrape off the paint remaining on the inner wall of the paint mixing tank 1, reducing paint residue, thereby bringing convenience to cleaning. When cleaning, the sealing cover 2 can be removed and cleaned separately. In the process of introducing water into the paint mixing tank 1 and discharging water for cleaning, due to the floating effect of the float 6, the scraper assembly can be driven up and down to repeatedly scrape off the paint on the inner wall of the paint mixing tank 1, thereby improving the cleaning effect.

[0021] The outsides of the paint mixing tank 1 and the sealing cover 2 are symmetrically installed with fixing blocks 10, and threaded holes are opened inside the fixing blocks 10. The threaded holes are threadedly connected with threaded rods 11. When installing, the fixing blocks 10 on the outsides of the paint mixing tank 1 and the sealing cover 2 are aligned, and the threaded rods 11 are inserted into the threaded holes for fixing, which facilitates installation and disassembly.

[0022] The first stirring plate 8 and the second stirring plate 9 are both spiral plates, and the spiral directions of the two spiral plates are opposite.

[0023] A plurality of evenly distributed hexagonal through holes 12 are formed on the surfaces of the first stirring plate 8 and the second stirring plate 9 .

[0024] During stirring, the servo motor will drive the first stirring plate 4 to rotate in a counterclockwise direction. At this time, the upper surface of the first stirring plate 8 pushes the paint, causing the sediment in the paint to move upward, and at the same time drives the second stirring plate 9 to rotate in a clockwise direction, so that the lower surface of the second stirring plate 9 pushes the paint, causing the paint to rotate downward, forming a reverse vortex in the paint mixing tank 1, colliding with the paint rotating upward at the bottom, avoiding the phenomenon that the paint is always rotating in the same direction, forming a large vortex inside the paint, alleviating the sedimentation phenomenon, and part of the paint will pass through the position of the hexagonal through hole 12, so that the paint forms a small vortex near the hexagonal through hole 12, thereby improving the stirring effect, avoiding the sediment from gathering at the bottom of the paint mixing tank 1, and making the mixing more uniform.

[0025] The scraper assembly includes a fixed ring 13 connected to the mounting ring 5 and a scraper 14 installed on the outside of the fixed ring 13. A number of evenly distributed springs 15 are fixedly connected to the outer surface of the mounting ring 5. The other ends of the springs 15 are connected to the fixed ring 13. The scraper 14 is used to scrape off the paint remaining on the inner wall of the paint mixing tank 1. The spring 15 pushes the scraper 14 to make the scraper 14 in close contact with the inner wall of the paint mixing tank 1, thereby improving the cleaning effect.

[0026] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
