Problems solved by technology

Although the principles of the above methods are different, they all condense fiber hairiness by pumping air, which consumes a lot of power and increases energy consumption. It is contrary to the advocated green processing and energy saving and emission reduction, but consumes a lot of energy and increases costs.
Although the above method can improve the quality, the investment in updating equipment and huge energy consumption will lead to an increase in cost, and the short-term profit margin is small. Moreover, the pressure and survival space of the enterprise will be greatly challenged by the replacement of this method.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a high-quality, low energy consumption, less hairiness and high-strength spinning technology for cotton yarn, viscose yarn, polyester yarn, wool yarn and wool-type chemical fiber yarn. Background technique [0002] The evenness of spun yarn is one of the important qualities that determine its quality, and it is also one of the important indicators to measure the price of spun yarn and its products. The main way to improve the evenness of the spun yarn is to transfer the yarn hairiness to the yarn body as much as possible. Therefore, in recent decades, one of the key technologies of the ring spinning system based on cotton spinning and wool spinning is to effectively transfer the hairiness on the surface of the yarn, reduce the protruding length of the hairiness, and improve the utilization rate of fibers. It is also a key problem for scientists and industrialists in the textile ...
