You mean the emitter rotates around the axis when the particle is launched?

In this case, emitter K should be given a rotating key frame during particle emission.

Click the set key, and then give the rotation key frame on the transmitter K through the button of this key.

If the center of the axis to be circled is outside the transmitter, the position of the axis can be adjusted first, and then the rotation animation of the transmitter can be K-tuned.

I don't know if you want the above effect. If not, you can clearly describe the effect you want.

I hope my answer is useful to you.
