Bobbin assembly capable of realizing peripheral unwinding

Abstract

The invention discloses a bobbin assembly capable of realizing peripheral unwinding. The bobbin assembly comprises a bobbin, wherein a rotating shaft is arranged in the bobbin; a rotary elastic component is arranged between the rotating shaft and the bobbin; one end of the rotary elastic component is connected with the rotating shaft; the other end of the rotary elastic component is connected with the bobbin. The rotary elastic component is a coil spring, a torsional spring, a corrugated telescopic spring or a rubber band. The rotating shaft and the bobbin are rotatably connected through a bearing. The bearing is adjacent to the rotary elastic component, and an isolation retainer ring is arranged between the bearing and the rotary elastic component. According to the bobbin assembly disclosed by the invention, cheese is fixedly arranged on the bobbin of the bobbin assembly in a sleeving manner and used as warp yarns for 3D weaving, the unwound warp yarns are always at a tensioned state, are not easily entwined per se and are further not easily twined with other yarns, and therefore normal proceeding of 3D weaving can be ensured and the quality of a 3D fabric is greatly improved.

Description

technical field [0001] The invention relates to a winding component used in the textile industry for filaments, yarns and threads, in particular to a bobbin assembly for circumferentially unwinding. Background technique [0002] Cylindrical packages (slender) or disc packages (stubby) of the prior art are usually unwound circumferentially. The bobbin is fixedly placed on the bobbin, and the bobbin is rotatably set on the spindle. There is sufficient friction between the bobbin and the spindle. When unwinding in the circumferential direction, the unwound yarn drives the bobbin to rotate, and the bobbin The yarn drives the bobbins to rotate. Since the yarn tension of the package is difficult to maintain evenly during the winding process, it is also difficult to maintain uniform tightness of the package yarn. Furthermore, since the package yarn is used as the warp yarn in 3D weaving, the warp yarn tension changes greatly due to the change of the shed size during the unwinding...

AI Technical Summary

Problems solved by technology

Since the yarn tension of the package is difficult to maintain evenly during the winding process, it is also difficult to maintain uniform tightness of the package yarn

Furthermore, since the package yarn is used as the warp yarn in 3D weaving, the warp yarn tension changes greatly due to the change of the shed size during the unwinding process, and the unwound yarn is often in a loose state, and the loose yarn is easy to cause its own Tangling, or entanglement with other warp yarns, will eventually affect the normal progress of 3D weaving and reduce the quality of 3D fabrics
