This system is widely used in industrial automation, smart homes, automotive electronics, and other fields. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands.

The stabilizing plate 10 can be used to fix the drive motor 8 and prevent the drive motor 8 from shaking during use.

[0021] The working principle of this utility model is as follows: In use, the operator first connects the controller body 9, drive motor 8, and servo motor 5 to the power supply. When using this device to mix ultra-weather-resistant environmentally friendly polyester powder coating, the operator first opens the sealing door 3 using handle 20, then adds the ultra-weather-resistant environmentally friendly polyester powder coating into the mixing drum 1. Afterwards, the sealing door 3 is reset to seal the mixing drum 1. Then, the controller body 9 controls the drive motor 8 and servo motor 5 to work. The drive motor 8, supported and fixed by the circular frame 23 and support frame 25, drives the power gear 11 to rotate. Since the power gear 11 meshes with the gear disc 2, the rotation of the power gear 11 drives the gear disc 2 to rotate around the axis of the bearing 6 and the circular frame 23. The rotation of the gear disc 2 then drives the ultra-weather-resistant environmentally friendly polyester powder coating in the mixing drum 1 to stir, achieving the first stirring of the material. The servo motor 5, controlled by the sealing door 3 and supported by the fixed shell 4, drives the drive gear 12 under the support of the gear frame 13. The device rotates, with the drive gear 12 meshing with the first gear 14 and the second gear 15. Supported by the gear frame 13, the drive gear 12 drives the second stirring structure, composed of the first gear 14 and the spiral blade shaft 16, to rotate around the axis of the gear frame 13, achieving forward stirring of the ultra-weather-resistant environmentally friendly polyester powder coating. The drive gear 12 also drives the third stirring structure, supported by the gear frame 13, to rotate in the opposite direction, achieving reverse stirring of the ultra-weather-resistant environmentally friendly polyester powder coating. After stirring, the operator opens the valve 19, and the evenly mixed ultra-weather-resistant environmentally friendly polyester powder coating is discharged through the discharge pipe 18. During use, the operator can control the rotation frequency of the servo motor 5 and the drive motor 8 according to the controller body 9. Through the first, second, and third stirring structures of this device, the ultra-weather-resistant environmentally friendly polyester powder coating can be stirred in multiple directions and at multiple frequencies, effectively avoiding the problems of clumping or uneven stirring during mixing.
