Correspondingly, a connecting mechanism for installing into the installation groove 211 is arranged at the lower end of the cup holder 22. At the same time, a driving mechanism for driving the male turntable 21 to rotate is arranged on the mixing chamber 1. In addition, a self-rotating transmission mechanism is arranged in the mixing chamber 1.

[0026] The connecting mechanism includes a bearing 23 and an installation rod 24. Among them, the installation rod 24 is fixedly connected to the lower end of the cup holder 22 and sleeved in the installation groove 211, and the bearing 23 is sleeved between the installation rod 24 and the installation groove 211.

[0027] The driving mechanism includes a motor 31, a first synchronous pulley 32, a second synchronous pulley 33, a synchronous belt 34 and a rotating shaft 35. Among them, the motor 31 is fixedly arranged on the outer side wall of the stirring chamber 1 and its output end is connected with the first synchronous pulley 32. The rotating shaft 35 is fixedly arranged at the lower end of the male turntable 21. The rotating shaft 35 penetrates downward through the stirring chamber 1 and its lower end is fixedly provided with the second synchronous pulley 33. Finally, the synchronous belt 34 is sleeved outside the first synchronous pulley 32 and the second synchronous pulley 33.

[0028] The self-rotation transmission mechanism includes a self-rotating disc 41 fixedly arranged inside the stirring chamber 1. The self-rotating disc 41 is arranged below the male turntable 21. At the same time, an annular transmission groove 42 is formed on the upper end surface of the self-rotating disc 41. The transmission groove 42 is concentric with the male turntable 21. Teeth are arranged on the side wall of the transmission groove 42. In addition, the mounting rod 24 extends downward and penetrates through the male turntable 21. The lower end of the mounting rod 24 is fixedly provided with a gear 43. The gear 43 is meshed in the transmission groove 42.

[0029] A limiting disc 51 is bolted on the male turntable 21. A plurality of through holes 52 are formed on the limiting disc 51 corresponding to the mounting grooves 211. The through holes 52 are used for the mounting rod 24 to pass through. The lower end of the limiting disc 51 is used to abut against the upper end surface of the bearing 23. At the same time, a plurality of limiting posts 53 are arranged along the circumferential direction on the lower end surface of the limiting disc 51.

Then the limiting disc 51 is installed on the male turntable 21. At this time, the corresponding number of cup holders 22 can be installed according to the actual number of containers to be operated. When the motor 31 starts to work, the motor 31 is used to drive the male turntable 21 to rotate, so that the cup holders 22 installed on the male turntable 21 perform a revolution. During the rotation of the cup holders 22, the gear 43 at the lower end of the second connecting rod 242 can revolve in the transmission groove 42 along with the cup holders 22. At this time, affected by the meshing of the gear 43 and the transmission groove 42, the gear 43 will drive the cup holders 22 to rotate while rotating. During the rotation of the cup holders 22, the limiting disc 51 can play a limiting role to prevent the bearing 23 from leaving the male turntable 21 under the influence of centrifugal force.
