AI Technical Summary
During the mixing operation, existing paint mixers need to align the center position of the material barrel with the stirring shaft, which is prone to collision and wear, and it is difficult to fully mix the materials on the barrel wall and bottom, resulting in uneven distribution of the paint and affecting the quality and efficiency of the protective layer.
The positioning ring and lifting mechanism are used to cooperate with the mixing mechanism, and the material barrel is positioned by itself. The brush body below the stirring wheel is designed as an annular array to tilt the barrel wall material to avoid collision and improve stirring uniformity.
Self-positioning stirring without alignment is achieved, avoiding wear, improving stirring uniformity and production efficiency, and shortening stirring time.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paint mixers, and more particularly to a paint mixer for metal surface treatment. Background Art
[0002] The Dacromet process is an advanced metal surface treatment technology that forms a dense protective layer with excellent corrosion and heat resistance and high adhesion by coating the metal surface with a mixed coating containing zinc flakes, aluminum flakes, an organic binder, and special additives. This protective layer significantly enhances the corrosion resistance of metal parts and extends their service life. It is widely used in the automotive, home appliance, and construction industries.
[0003] The preparation and application of Dacromet coatings also presents the problem of coating sedimentation. Due to differences in density and shape, metal particles such as zinc and aluminum flakes in Dacromet coatings tend to settle within the coating after prolonged standing, resulting in uneven coating concentration distribution. This not only affects the coating's application performance but can also adversely affect the formation and quality of the Dacromet protective layer.
[0004] Therefore, in the Dacromet process, ensuring the coating is in a uniform and stable state before application is crucial. Existing mixers have the following issues: During mixing, the material barrel must be placed directly below the agitator shaft. If this placement is off, the agitator wheel on the agitator shaft can easily contact the barrel, causing wear and tear. Furthermore, the agitator wheel must maintain a certain distance from the bottom and side walls of the barrel during operation. Material easily accumulates in these areas, making it difficult to fully mix, making it difficult to achieve a good mixing effect and resulting in low mixing efficiency. Utility Model Content

[0029] See also Figure 1-4The lifting mechanism includes a mounting base 2 provided on the base 1. The lifting mechanism in this scheme is a screw lifting mechanism commonly used in the prior art. A driving motor 3 is installed on the mounting base 2. The output end of the driving motor 3 is fixedly connected to a driving shaft 4. The end of the driving shaft 4 away from the driving motor 3 is fixedly connected to a driving gear 5. The side of the driving gear 5 is meshed and connected to a driven gear 6. A screw lifting assembly 7 is provided on the base 1. The screw in the screw lifting assembly 7 is fixedly connected to the driven gear 6. The outer end of the screw in the screw lifting assembly 7 is screwed with a lifting block 8. Starting the driving motor 3 for forward and reverse rotation can make the lifting block 8 perform corresponding lifting. A limiting rod 9 is provided on the base 1. The screw lifting assembly 7 and the limiting rod 9 are fixedly connected to the connecting rod 10. The rear end of the lifting block 8 is fixedly connected to the limiting block 11 A hole is provided on the limit block 11, and the limit rod 9 is arranged at the inner end of the limit block 11 and is slidably connected thereto. A number of spherical grooves are provided on the hole body, and a ball 1101 is rotatably connected in the spherical groove, thereby reducing the friction between the limit block 11 and the limit rod 9, so that the lifting block 8 fixedly connected thereto can move more smoothly when sliding up and down along the screw. The front end of the lifting block 8 is fixedly connected to a driven lifting platform 12, and a pair of reinforcement strips 19 are fixedly connected between the lifting block 8 and the driven lifting platform 12. A pair of reinforcement strips 19 are symmetrically distributed at the left and right ends of the lifting block 8.

[0030] See also Figure 1 、 Figure 2 as well as Figure 5 The stirring mechanism includes a stirring motor 13 mounted on a driven lifting platform 12, the output end of the stirring motor 13 is fixedly connected to a rotating shaft 14, and the end of the rotating shaft 14 away from the stirring motor 13 is fixedly connected to a stirring wheel 15, and the outer edges of the upper and lower ends of the stirring wheel 15 are provided with stirring blades 16 distributed in a ring array with their geometric center. The lower end of the stirring wheel 15 is fixedly connected to a brush body 17. Starting the stirring motor 13 can make the rotating shaft 14 drive the stirring wheel 15, the stirring blades 16 and the brush body 17 to rotate accordingly to stir the paint in the material barrel 18. The other end of the brush body 17 is closely fitted with the bottom and side wall of the material barrel 18. The brush body 17 is obliquely arranged below the stirring wheel 15 in the form of a ring array and is closely unfolded around the central axis of the stirring wheel 15. The brush body 17 is inclined at a 45° angle in the vertical direction, as shown in FIG. Figure 5As shown, one end of the brush body 17 is connected to the lower end of the stirring wheel 15 and rotates with the rotating shaft 14, using the power generated by the rotation to stir the material. The other end is cleverly designed to fit closely with the bottom and side walls of the material barrel 18, but not directly in contact, so as to maintain an appropriate gap to avoid friction and wear. This design ensures that the brush body 17 can fully contact and stir the material, and avoids direct collision with the inner wall of the material barrel 18, thereby extending the service life of the brush body 17 and the material barrel 18. The spacing between each brush body 17 is consistent, which can ensure that a uniform and continuous stirring effect can be formed during the rotation process, thereby improving the uniformity and efficiency of material mixing. The stirring wheel 15, the stirring blade 16 and the brush body 17 are all made of stainless steel with excellent corrosion resistance, and their surface is smooth and not easy to adhere to materials, so they are easy to clean and maintain.
[0031] Before the mixing operation, when the material barrel 18 is placed at the positioning ring 101, the lifting block 8 moves along the screw lifting assembly 7 to the position as shown in FIG. Figure 1 In the mixing process, when the bottom of the material barrel 18 is stirred, the lifting block 8 moves along the screw lifting assembly 7 to the position shown. Figure 2 shown.
[0032] This solution can achieve the goal of stirring materials without the need to deliberately align the center of the material barrel with the stirring shaft. After placement, it can position itself, thereby effectively avoiding collision and wear between the stirring wheel and the material barrel during operation. At the same time, the brush body under the stirring wheel can more effectively scrape off the material attached to the barrel wall and bottom, reducing dead angles, thereby improving the uniformity of stirring, shortening the stirring time, and improving production efficiency.
[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
