[0002] In the powder coating industry, the performance of the mixer is directly related to the uniformity, dispersion effect and production efficiency of the coating. Most of the common powder coating mixers on the market at present adopt traditional stirring methods, such as single-axis or multi-axis stirrers. Although they can achieve basic mixing functions, when dealing with high-viscosity and high-solid-content powder coatings, there are often problems such as uneven mixing, low dispersion efficiency, high energy consumption and serious dust pollution. In addition, the speed control of traditional mixers is relatively single, and it is difficult to flexibly adjust according to the coating characteristics and process requirements, resulting in unstable mixing quality and affecting the final quality of the coating.

[0018] The following will further elaborate on this application in conjunction with the attached drawings. Figures 1 - 3 A further detailed description of this application will be given.

[0019] An embodiment of this application discloses a highly dispersed high-speed powder coating mixer. Referring to Figures 1 - 3 , it includes a mobile frame 1. A column 2 is fixed on the mobile frame 1. A motor is installed inside the column 2. The output end of the motor is drivingly connected to a lead screw 3. A slider 15 is slidably arranged on the outer wall of the lead screw 3. One end of the slider 15 extends outside the column 2 and is fixed to a drive gearbox 4. Therefore, as the lead screw 3 rotates to drive the slider 15 to move, the drive gearbox 4 can be driven to lift, thus facilitating the adjustment of the height of the stirred powder coating. And an activity port 8 is opened inside one side of the mobile frame 1 to facilitate the movement and placement of the powder coating bucket for the stirring work.

[0020] As Figure 2 shown, an engine 10 is installed on one side of the bottom of the drive gearbox 4. A turntable 5 is arranged on one side of the bottom of the drive gearbox 4. When the engine 10 works to drive the transmission components inside the drive gearbox 4 to rotate, the turntable 5 can be driven to rotate. And electric push rods 16 are arranged on both sides of the bottom of the turntable 5. Both ends of the two electric push rods 16 are rotatably connected to a connecting member 17. One of the connecting members 17 is fixed to the bottom of the turntable 5, and the bottom end of the other connecting member 17 is fixed to a connecting seat 11. A rotating rod 6 is fixed at the center of the connecting seat 11. Therefore, as the turntable 5 rotates, the connecting seat 11 can be driven to rotate synchronously. And since a U-shaped stirring tube 7 is installed at the bottom end of the rotating rod 6, a plurality of air holes 20 are equidistantly arranged on the outer wall of the U-shaped stirring tube 7. And a hose 9 is connected to one side of the top of the drive gearbox 4. The hose 9 is used to connect an external high-pressure gas pump. And a connecting pipe 19 is connected inside the drive gearbox 4. One end of the hose 9 extends into the drive gearbox 4 and is connected to the connecting pipe 19. And the other end of the connecting pipe 19 extends into the rotating rod 6. Therefore, high-pressure gas can be conveyed into the U-shaped stirring tube 7 to facilitate the promotion of the dispersion of the powder coating through the blowing action of the high-pressure gas.

[0021] Combined with Figure 3 shown, a pneumatic motor 12 is connected to the bottom of the U-shaped stirring tube 7. The output end of the pneumatic motor 12 is connected to a stirring impeller 18. Strong shearing and collision effects are generated through the rotation of the stirring impeller 18 to further improve the mixing efficiency. A positioning sleeve 13 for support is fixed on the side wall of the column 2. An activity rod 14 adapted to it is movably arranged inside the positioning sleeve 13. One end of the activity rod 14 is fixed to the outer wall of the drive gearbox 4. Therefore, as the drive gearbox 4 is adjusted, the activity rod 14 will slide and be positioned inside the positioning sleeve 13 to further ensure the stability of the overall structure.

[0022] The implementation principle of a high-dispersion high-speed powder coating mixer in an embodiment of this application is as follows: During use, first move the material bucket containing the powder coating into the movable opening 8 inside the movable rack 1. Then, drive the lead screw 3 to rotate through the motor. Subsequently, the slider 15 drives the transmission case 4 to perform a lifting motion inside the column 2, driving the U-shaped stirring tube 7 into the material bucket to mix the powder coating. Then, drive the transmission components inside the transmission case 4 by the engine 10 to drive the turntable 5 to rotate. Subsequently, drive the connecting seat 11 to rotate synchronously through the electric push rod 16. At this time, the powder coating in the material bucket can be stirred through the U-shaped stirring tube 7. At the same time, connect an external high-pressure gas pump through the hose 9, and the gas is pumped into the inside of the rotating rod 6 through the connecting pipe 19. Subsequently, the high-pressure gas is ejected from the air holes 20 inside the U-shaped stirring tube 7 to promote the dispersion of the powder coating. Also, drive the stirring impeller 18 to rotate through the pneumatic motor 12 to generate a strong shearing and collision effect, further improving the mixing efficiency, enabling the powder coating to be more fully dispersed and uniformly mixed during the mixing process, improving the coating quality. According to the mixing situation, the electric push rod 16 can be started. As the electric push rod 16 expands and contracts, the connecting seat 11 changes its angle along with the connecting member 17. At this time, the connecting seat 11 can be driven to tilt at an angle, that is, the mixing angle of the stirring impeller 18 can be adjusted, further enhancing the mixing effect of the powder coating, and being able to be flexibly adjusted according to the coating characteristics and process requirements.
