Yarn guide mechanism of spinning frame

The utility model belongs to the field of spinning equipment, particularly relates to a yarn guide mechanism of a spinning frame, and aims to solve the problem that winding of different yarns may be affected due to the fact that the conventional yarn guide wheel does not have a height adjusting function and is difficult to tension the yarns in the yarn guide process when guiding the yarns with different thicknesses or different requirements. According to the scheme, the yarn guiding device comprises a rotating mechanism arranged on a fixing sleeve seat and used for rotating a yarn guiding wheel; the adjusting mechanism is arranged on the rotating mechanism and used for adjusting the height of the yarn guide wheel. When the yarn guide wheel is used, the yarn guide wheel can be adjusted to different heights, so that the adjusted yarn guide wheel can tighten yarns in the yarn guide process, winding of different yarns is facilitated, and the problem that the yarn guide wheel does not have the height adjusting fun
