DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] Refer to the drawings of the utility model Figs. 1 to 5 According to the double-shaft rotating frame structure of the liquid flow battery electrolyte container of the utility model embodiment, it comprises:

[0030] The mobile base 1 is fixed with the stand 2 on both sides, the outer frame rotating motor 3 and the inner frame rotating motor 4 are fixed on one side of the stand, and two power sources drive the rotation of the outer frame and the inner frame respectively, and they do not interfere with each other;

[0031] The rotating outer frame 5 is located between the two stands, and the rotating outer frame 5 is connected with a rotating shaft 6 and a hollow shaft 7 at the middle of the two side ends, respectively. The rotating shaft 6 and the hollow shaft 7 are rotatably installed on the stand 2 through bearings. Two-point support can provide a more stable rotating foundation for the outer frame and can also improve the load capacity of the outer frame, adapt to the production and manufacturing requirements of super-large workpieces, and the hollow shaft 7 is close to the side stand where the motor is arranged.

The inside of the hollow shaft 7 rotates with a power connection shaft 8. The power connection shaft 8 is in transmission connection with the output end of the inner frame rotating motor 4. It should be noted that the rotation of the power connection shaft does not affect the rotation of the hollow shaft, thereby realizing the independent driving effect of the rotating outer frame 5 and the rotating inner frame 9.

[0032] The rotating inner frame 9 is located inside the rotating outer frame 5. The two ends of the rotating inner frame 9 are rotatably connected with the two ends of the rotating outer frame 5 through support shafts 10. The rotating direction of the rotating inner frame 9 is perpendicular to the rotating direction of the rotating outer frame 5. The purpose is to realize the continuous rotating process of the mold along two perpendicular axes, thereby completing the rotating molding production process. The rotating inner frame 9 is provided with four fixing seats 11 for installing molds 17. These fixing seats realize the fixed assembly of the molds 17 and the rotating inner frame 9.

[0033] The worm gear transmission mechanism 12 is installed on the rotating outer frame 5. The worm gear 121 in the worm gear transmission mechanism 12 rotates synchronously with the support shaft 10.

A sprocket is connected to the other end of the power connection shaft 8. A transmission chain 14 is connected to the sprocket. The transmission chain 14 is in transmission connection with the worm 122. The sprocket chain transmission can reduce the space limitation and adapt to harsh transmission environments.
