摘要: 浆叶导纱机构属接力换向导纱机构,采用正、反两个方向转动的浆叶推动纱线做往复运动。在往复动程末端必须实现浆叶对纱线控制的轮换。通过分析几种进口高速卷绕头和精密络筒机浆叶导纱机构的导纱机理,提出了这类机构的设计方法,给出了设计的通用公式,并通过实例证明了设计理论的正确性。该设计方法和推导的公式可为设计同类机构借鉴。

Abstract: The thread guide mechanism of rotary blades belongs to the one of changing direction by relay,(i.e.,) the back and forth motion of yarns is guided by two rotary blades rotating in the opposite directions and as soon as the yarns travel to the end of the stroke,they change their directions through exchanging positions on the rotary blades.The thread guiding mechanism of several kinds of imported high speed take-up machines and precise winders is analyzed,and the design method of this kind of thread guide mechanism is proposed for the first time.General formulas for this design are derived and the design theory has been proven correct by illustrative examples.This design method and formulas may be used for reference in designing the same kind of mechanism.
