[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A paint grinding and mixing device includes a mixing tank 1, a grinding tank 2 rotatably connected to the mixing tank 1, a grinding roller 3 disposed inside the grinding tank 2, the grinding roller 3 being inclinedly disposed inside the grinding tank 2, a protective shell 4 disposed on the grinding tank 2, two side plates of the protective shell 4 being connected to the top of the mixing tank 1, a drive motor 5 disposed on the protective shell 4, a drive shaft 6 being connected to the output shaft of the drive motor 5, the bottom end of the drive shaft 6 extending into the grinding tank 2 and being connected to the grinding roller 3 through a connector, a plurality of filter holes 7 being disposed at the bottom of the grinding tank 2, and an opening being disposed at the top of the mixing tank 1, the plurality of filter holes 7 being coaxial with the opening.

[0023] When using this device, the paint is placed in the grinding barrel 2, the drive motor 5 is started, and the drive shaft 6 drives the grinding roller 3 to rotate, thereby achieving the purpose of grinding the paint. Through this grinding operation, the paint particles are made finer, so that they can meet the production requirements of high-fineness paint. After that, the ground paint is transported to the mixing barrel 1 through several filter holes 7 set at the bottom of the grinding barrel 2, so as to realize the mixing and paint adjustment of various colors of paint.

[0024] Specifically, in this embodiment, a first bevel gear 8 is connected to the upper part of the drive shaft 6, a second bevel gear 9 meshes with the first bevel gear 8, and a third bevel gear 10 meshes with the second bevel gear 9. The third bevel gear 10 is connected to the top of the grinding barrel 2, so that when the drive shaft 6 rotates, it can drive the first bevel gear 8 to rotate synchronously, thereby driving the second bevel gear 8 to rotate. The second bevel gear 9 pushes the third bevel gear 10 to rotate in the opposite direction of the first bevel gear 8, so that the grinding barrel 2 connected to the third bevel gear 10 rotates in the opposite direction of the grinding roller 3, thereby further improving the grinding efficiency of the coating.

[0025] Specifically, in this embodiment, the drive shaft 6 passes through the third bevel gear 10 and extends into the grinding barrel 2, so that the first bevel gear 8 and the third bevel gear 10 are coaxially arranged, which can ensure the normal rotation of the grinding roller 3 driven by the drive shaft 6.

[0026] Specifically, in this embodiment, a gearbox 11 is provided on the protective housing 4. The first bevel gear, the second bevel gear 9, and the third bevel gear 10 are all located inside the gearbox 11. The drive motor 5 is installed on the top of the gearbox 11, and its output shaft passes through the top of the gearbox 11 and is connected to the first bevel gear 8. The gearbox 11 can isolate the first bevel gear, the second bevel gear 9, and the third bevel gear 10 from the outside world, thereby preventing foreign objects from entering the transmission components and affecting the normal operation of the device.

[0027] Specifically, in this embodiment, a toothed ring 12 is provided on the outer curved surface of the bottom of the grinding barrel 2. Several stirring gears 13 are meshed on the toothed ring 12. The stirring gears 13 are located on the top of the mixing barrel 1. The bottom ends of the stirring gears 13 are all connected to stirring rods 14. The stirring rods 14 are located inside the mixing barrel 1, so that when the grinding barrel 2 rotates, it can drive the stirring gears 13 to rotate through the toothed ring 12, thereby driving the stirring rods 14 to rotate, thereby achieving the purpose of stirring the coating in the mixing barrel 1.

[0028] Specifically, in this embodiment, each of the stirring rods 14 is provided with a scraper 15. The scraper 15 can contact the inner wall of the mixing tank 1, so that the stirring rods 14 can rotate while the scraper 15 rotates, thereby achieving the purpose of cleaning the wall of the mixing tank 1 by rotating the scraper 15, which provides convenience for subsequent cleaning work.

[0029] Specifically, in this embodiment, the top of the grinding barrel 2 is provided with a feed inlet 16, and a cover plate 17 is hinged to the feed inlet 16. The protective shell 4 is provided with a connecting groove 18. The coverage area of ​​the connecting groove 18 is larger than that of the feed inlet 16, so that the paint can be put into the grinding barrel 2 through the feed inlet 16. Then, the feed inlet 16 is covered by rotating the cover plate 17, thereby avoiding dust during grinding. The connecting groove 18 makes it easy to control the opening and closing of the feed inlet 16 through the protective shell 4.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
