Description

An air spinning drawing frame

technical field

The utility model relates to the technical field of textiles, in particular to an air-flow spinning drawing frame.

Background technique

Open-end spinning is a new type of spinning technology that uses air flow to condense, twist and output fibers in a high-speed spinning rotor. He does not use spindles, but mainly relies on opening rollers, spinning rotors, false twisting devices and other components. The opening roller is used to grab and card the fed sliver fibers, and the centrifugal force generated by its high-speed rotation can throw the grabbed fibers out. The spinning rotor is a small metal cup, and its rotation speed is more than 10 times higher than that of the combing roller. The centrifugal action generated by this causes the air in the cup to be discharged outward; according to the principle of fluid pressure, the cotton fibers enter the airflow cup. , and form a fiber flow that continuously moves along the inner wall of the cup. The draw frame is an important equipment in the air spinning process. Its function is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, and at the same time reducing the weight unevenness, so that the fibers in the sliver are straight and parallel, reducing hooks and making The fineness is in compliance with the regulations, so that the raw materials of different types or different qualities can be mixed evenly to achieve the specified mixing ratio. Because cotton wool and long lint often exist on the surface of the sliver, a large amount of dust will be caused during the drawing process, which will affect the surrounding environment and be detrimental to the health of the staff.
