[0018] Please refer to Figures 1-3 As shown, this utility model is a double-helix fluid mixing device, including a mixing tank 1, an outer ring 2, and a spiral stirring rod 3. The outer ring 2 is installed on the upper surface of the mixing tank 1. The inner wall of the outer ring 2 is provided with a toothed groove 13. Two sets of driven wheels 10 are meshed inside the toothed groove 13. The inner sides of the two sets of driven wheels 10 are meshed with a transmission wheel 14. The upper surface of the transmission wheel 14 is connected to a transmission shaft 11. The upper end of the transmission shaft 11 extends upward through the outer ring 2 and is connected to a servo motor 8. A connecting plate 18 is installed on the outer side of the transmission shaft 11. The two ends of the connecting plate 18 are rotatably installed on the upper ends of the two sets of driven wheels 10. Two sets of spiral stirring rods 3 are provided and are respectively installed on the lower surfaces of the two sets of driven wheels 10.

[0019] In use, the driven wheel 10 is driven to rotate around the outer ring 2 by the connecting plate 18, which in turn drives the spiral stirring rod 3 to stir around the inside of the mixing box 1. The driven wheel 10 is driven to rotate by the transmission wheel 14, which in turn drives the connected spiral stirring rod 3 to rotate, so that the fluid in the mixing box 1 can be driven to roll upward, which greatly improves the mixing efficiency.

[0020] Please refer to Figure 3 A connecting rod 15 is connected to the lower surface of the transmission wheel 14. A horizontal plate 16 is connected to the lower end of the connecting rod 15. Scrapers 17 are connected to both ends of the horizontal plate 16. The scrapers 17 are located inside the mixing box 1. When the transmission wheel 14 rotates, it can drive the connecting rod 15 to rotate. The rotation of the connecting rod 15 drives the horizontal plate 16 and the scrapers 17 to rotate, thereby scraping off the fluid adhering to the inner wall of the mixing box 1, which greatly improves the mixing uniformity.

[0021] Please refer to Figure 1 A mounting bracket 9 is installed on the upper surface of the outer ring 2. The servo motor 8 is mounted on the upper surface of the mounting bracket 9. The mounting bracket 9 is used to fix the servo motor 8 in place to prevent shaking during operation.

[0025] Working Principle: This utility model is a double-helix fluid mixing device. First, the fluid to be mixed is put into the mixing tank 1 through the feed port 7. Then, the servo motor 8 is started to drive the transmission shaft 11 to rotate. The rotation of the transmission shaft 11 drives the transmission wheel 14 and the connecting plate 18 to rotate. The rotation of the connecting plate 18 and the transmission wheel 14 can simultaneously drive the two sets of driven wheels 10 to rotate around the toothed grooves 13 opened on the inner wall of the outer ring 2. The connecting plate 18 drives the driven wheels 10 to rotate around the outer ring 2, thereby driving the spiral stirring rod 3 to stir around the inside of the mixing tank 1. The transmission wheel 14 drives the driven wheels 10 to rotate, thereby driving the connected spiral stirring rod 3 to rotate, which can drive the fluid in the mixing tank 1 to roll upward.
