Description

Technical Field

[0001] The utility model relates to the technical field of spinning devices, in particular to an air-spinning device. Background Art

[0002] Air-jet spinning is a new type of spinning production method. The working principle of air-jet spinning is completely different from that of ring spinning. It relies on the feeding roller and the feeding plate to actively feed the sliver forward, which is combed into single fibers by the combing roller. Due to the vacuum formed in the spinning cup, the external air flow is forced to be replenished from the air supply port and the yarn guide tube, thereby carrying the combed single fibers into the spinning cup through the cotton tube to form condensed whiskers. When the yarn passes through the yarn guide tube, it is sucked into the condensation groove and connected with the whiskers. The centrifugal force generated by the high-speed rotation of the spinning cup makes the yarn tail adhere to the surface of the condensation groove, which is held and twisted into yarn, and then led out through the twisting disk and the yarn guide tube and rolled into a bobbin.
