[0083] The implementation principle of the power mechanism of a planetary mixing device in the embodiment of the present application is as follows: the first motor 3 is working, the output shaft of the first motor 3 rotates, thereby driving the first driving wheel 5 to rotate, the first driving wheel 5 drives the first driven wheel 6 meshed with it to rotate, and the first driven wheel 6 drives the rotation shaft 1 fixedly connected to it to rotate; the second motor 4 is working, the output shaft of the second motor 4 rotates, thereby driving the second driving wheel 7 to rotate, the second driving wheel 7 drives the second driven wheel 8 meshed with it to rotate, the second driven wheel 8 drives the revolution shaft 2 fixedly connected to it to rotate, and the revolution shaft 2 rotates relative to the rotation shaft 1;

In addition, the first driving wheel 5 and the first driven wheel 6, the second driving wheel 7 and the second driven wheel 8 all adopt bevel gear meshing transmission. The first motor 3 and the second motor 4 are respectively arranged on the sides of the rotation shaft 1 and the revolving shaft 2. The front ends of the output shafts of the first motor 3 and the second motor 4 can be as close to the central axes of the rotation shaft 1 and the revolving shaft 2 as possible. The space occupied by the first motor 3 and the second motor 4 along the radial direction of the rotation shaft 1 can be minimized. At the same time, since the first driving wheel 5 and the first driven wheel 6, the second driving wheel 7 and the second driven wheel 8 all adopt bevel gear meshing transmission, the first motor 3 and the second motor 4 are placed in a bedroom. Therefore, the space occupied by the first motor 3 and the second motor 4 in the axial direction of the rotation shaft 1 can be minimized.
