The stirring rod 5 stirs the chemical fiber oil agent raw material, which can evenly mix the oil agents of different components, ensure full contact between them, prevent precipitation and stratification, and ensure the uniformity and stability of the chemical fiber oil agent.

The staff sets the stirring time of the first stage, the stirring time of the second stage and the stirring time of the third stage on the timer 9. In the first stage, the driving motor 4 mixes at a low speed for 5 minutes to ensure that all batches of raw materials are evenly mixed.
