In the solution of the present utility model, the first stirring paddle 21, the second stirring paddle 32, and the third stirring paddle 42 form a triple stirring structure, specifically, as Figure 3 As shown, the first stirring paddle 21 is a rectangular frame, the second stirring paddle 32 and the third stirring paddle 42 are L-shaped, a positioning shaft 23 is provided at the bottom of the first stirring paddle 21, and the second stirring paddle 32 and the third stirring paddle 42 are movably connected to the positioning shaft 23, wherein the first connecting shaft 2 is in the most central position, and the first stirring paddle 21 rotates in the form of self-rotation; the second connecting shaft 31 is connected to the first turntable 13 through the first connecting hole 131, and the second stirring paddle 32 rotates around the positioning shaft 23 as the center; the third connecting shaft 41 is connected to the second turntable 14 through the second connecting hole 141, and the third stirring paddle 42 rotates around the positioning shaft 23 as the center. The first stirring paddle 21, the second stirring paddle 32, and the third stirring paddle 42 form concentric circle motion trajectories when rotating, which can perform triple stirring on the material, and the material mixing quality is high.

[0026] In the driving structure of the first motor 5 and the second motor 6, the central portion of the support 1 is provided with a notch 17 communicating with the through hole 11, and the first connecting shaft 2 is provided with a first transmission gear 22 at a position corresponding to the notch 17. The first connecting shaft 2 can be driven to rotate by gear transmission.

[0027] More specifically, the first motor 5 is a dual-axle motor. A first power gear 51 is provided at one end of the first motor 5 to drive the first transmission gear 22. Two connecting gears 25 are provided between the first power gear 51 and the first transmission gear 22. The first power gear 51 indirectly drives the first transmission gear 22 to rotate via the connecting gears 25. The first transmission gear 22 rotates in opposite directions to the first power gear 51.

[0028] The second connecting plate 4 is provided with a second transmission gear 43 that is sleeved on the outside of the support 1. The other end of the first motor 5 is provided with a second power gear 52 that can mesh with the second transmission gear 43. The second power gear 52 rotates in the same direction as the first power gear 51. The second transmission gear 43, which is directly meshed with the second power gear 52, rotates in the same direction as the first transmission gear 22. In this embodiment, the first motor 5 can drive the first stirring paddle 21 and the third stirring paddle 42 to rotate, and the first stirring paddle 21 and the third stirring paddle 42 rotate in the same direction.

During the stirring process, the first stirring paddle 21, the second stirring paddle 32, and the third stirring paddle 42 can stir the material. The planetary mixer of this utility model is particularly suitable for stirring high-viscosity materials such as silica gel raw materials, and has strong stirring force and high efficiency.

[0030] A fixing frame 7 is provided on the outside of the pillar 1, and the first motor 5 and the second motor 6 are mounted on the fixing frame 7. When the planetary mixer of the present invention is in operation, the pillar 1 is fixed and the fixing frame 7 fixes the first motor 5 and the second motor 6. After the first motor 5 and the second motor 6 are started, the torque force generated will be dispersed to the fixing frame 7 and the pillar 1, thereby improving the stability of the first motor 5 and the second motor 6.

[0032] The first stirring paddle 21 is provided with a plurality of inclined rods 24 in the middle. The first stirring paddle 21 is a rectangular frame. When it rotates, a cylindrical cavity is formed in the middle, which easily accumulates materials and causes uneven stirring. The inclined rods 24 can break up the materials in the first stirring paddle 21 and improve the stirring quality.

[0033] The planetary agitator comprises an outer shell 8 fixedly connected to the support 1. The bottom of the outer shell 8 is provided with a tail plate portion 81 movably connected to the second turntable 14. The second turntable 14, the first turntable 13, and the fixed plate 12 cooperate to separate the planetary agitator into upper and lower sections. The first, second, and third stirring paddles 21, 32, and 42 are located at the lower section, while the support 1 is located at the upper section. The outer shell 8 covers the upper section of the planetary agitator, and the tail plate portion 81 seals the outer edge of the second turntable 14, preventing material from seeping into the interior of the planetary agitator during mixing. The structure is stable, the sealing is high, and the service life is long.
