Three-point mutual wrapping and winding type spun yarn evening and ordering device and method

The invention provides a three-point mutual wrapping and winding type spun yarn evening and ordering device and method. The three-point mutual wrapping and winding type spun yarn evening and ordering device comprises a three-point mutual wrapping and winding mechanism. The three-point mutual wrapping and winding mechanism comprises a fixing frame, a stepping motor, a worm, a drive gear, a first transmission gear, a first winding and pasting roller, a second transmission gear, a second winding and pasting roller, a third transmission gear, a third winding and pasting roller and a first yarn guiding hook. The worm on the stepping motor is coupled with the drive gear, and the first winding and pasting roller is sleeved with the first transmission gear. The second winding and pasting roller is sleeved with the second transmission gear. The third winding and pasting roller is sleeved with the third transmission gear. The drive gear drives the first transmission gear, the second transmission gear and the third transmission gear to rotate. The three-point mutual wrapping and winding mechanism is additionally arranged on a ring spinning frame, the fluctuation of an air ring is effectively controlled, a spun yarn is stabilized to be evenly output, the silver evenness is improved, and the yarn quality is improved.
