Description

Technical Field

[0001] The utility model relates to the technical field of production auxiliary devices for ring spinning frames, in particular to a yarn tube head-feeding winding device for a spinning frame. Background Art

[0002] A spinning frame is a spinning machine that drafts, twists, and winds semi-finished roving or sliver into yarn tubes during the spinning process. The sliver is drafted and twisted into roving on a roving frame, the fiber is carded into combed sliver on a comber, the sliver is combined on a gill box, and the needle bar drafts to improve the sliver structure. The roving is further twisted into yarn on a ring spinning frame. The spinning frame is the main machine for spinning.

[0003] During the operation of the spinning frame station, the problem of yarn breakage often occurs. Currently, when the yarn breaks at the spinning frame station, usually a robotic arm places the broken end of the yarn on one side of the yarn tube, and through the suction force generated by the rotation of the yarn tube, the broken end of the yarn is adsorbed onto the yarn tube and continues to be wound. In this way, local protrusions are likely to appear on the yarn tube after head-feeding, and the outer diameter of the yarn tube is likely to exceed the set value. Summary of the Utility Model
