Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a mixer for coating production. Background Art

[0002] Paints are usually composed of multiple ingredients, including solvents, resins, pigments, additives, etc. However, the uniformity of the paint is crucial to the quality of the coated surface. The mixer can ensure that the various ingredients in the paint are fully mixed to avoid problems such as pigment precipitation and solvent stratification. In general, the mixer plays a key role in the paint production process, ensuring the uniformity, stability and quality of the paint formula, improving production efficiency and reducing costs, thereby meeting the market demand for high-quality paints;

[0003] Traditional paint production mixers use one or more rotating stirring paddles or stirring blades to mix the paint formula through electric drive;

[0004] Conventional mixers for paint production have the following problems: although the stirring paddle or stirring blade can rotate in the paint, it may not be possible to completely achieve uniform mixing in some cases, especially when the paint formula contains a variety of viscous or difficult-to-mix ingredients. For this reason, we propose a mixer for paint production. Utility Model Content

The worm wheel 306 is fixedly sleeved on the bottom end of the rotating cylinder 301. The worm wheel 306 is meshed with the worm 307. The stirring mechanism 3 also includes a motor 305. The motor 305 is mounted on the right side of the housing 2 by bolts. The left end of the output shaft of the motor 305 is fixedly connected to the right end of the worm 307. The input end of the motor 305 is electrically connected to the output end of the single-chip microcomputer 5. Then, the single-chip microcomputer 5 is used to control the operation of the motor 305. The output shaft of the motor 305 drives the worm 307 to rotate. The worm 307 is meshed with the worm wheel 306, which makes the worm wheel 306 rotate with the rotation of the single-chip microcomputer 5. The rotation of the worm gear further drives the rotating cylinder 301 to rotate clockwise. The clockwise rotation of the rotating cylinder 301 drives the protective shell 302 to rotate clockwise.

Thus, the efficiency of coating mixing can be increased by combining clockwise stirring and counterclockwise stirring, making the stirring more thorough, and being able to better dissolve and mix a variety of viscous mixed materials. When the stirring blade 315 stirs, the avoidance port 314 reduces the resistance of the stirring blade 315 during the stirring process, making the stirring smoother and more efficient.

[0025] The working principle of a paint production mixer provided by the utility model is as follows: unmixed paint and mixed materials are poured into the interior of the mixing barrel 4, and then the single-chip microcomputer 5 is used to control the operation of the motor 305, and the output shaft of the motor 305 drives the worm 307 to rotate, and the worm 307 is meshed and connected with the worm wheel 306, which makes the worm wheel 306 rotate accordingly, and the rotation of the worm wheel further drives the rotating drum 301 to rotate clockwise. The clockwise rotation of the rotating drum 301 drives the protective shell 302 to rotate clockwise, and the rotation of the protective shell 302 finally drives the evenly distributed stirring rods 303 and stirring blades 315 to rotate clockwise, thereby realizing the process of preliminary stirring and mixing the paint, ensuring that the paint can be fully mixed to achieve the required uniformity and stability. At the same time, during the rotation of the rotating drum 301, the bevel gear 308 at the bottom also rotates accordingly, but during the rotation process The bevel gear 1 308 is meshed with the bevel gear 2 309, thereby driving the bevel gear 2 309 to rotate. The rotation of the bevel gear 2 309 drives the meshed bevel gear 3 310 to rotate together. The rotation of the bevel gear 310 drives the rotating shaft 312 to rotate counterclockwise between the inner wall of the rotating cylinder 301 and the bottom wall of the protective shell 302 through the bearing. The counterclockwise rotation of the rotating shaft 312 drives the evenly distributed stirring rod 2 304 and the stirring blade 315 fixed on the bottom fixing ring 311 to rotate counterclockwise for sufficient stirring and mixing. Therefore, the combination of clockwise stirring and counterclockwise stirring can increase the efficiency of coating mixing, make the stirring more thorough, and better dissolve and mix a variety of viscous mixed materials. However, when the stirring blade 315 is stirring, the avoidance port 314 is used to reduce the resistance of the stirring blade 315 during the stirring process, making the stirring smoother and more efficient.
