经编机成圈主要运动分析及其实现机构

经编机成圈运动装置的设计是研发经编机的关键，故分析槽针型经编机成圈运动中的主要运动——梳栉、槽针和针芯运动的要求，包括每种运动装置末段执行件的运动类型和运动变化规律。探讨在梳栉数较少情况下实现机构的选型，并对实例进行运动分析，获得了实际装置中梳栉和槽针之间的配合以及槽针针钩尖和针芯头端之间闭合的运动关系。根据三者之间的运动配合关系研究梳栉、槽针和针芯运动机构主动件之间的相位关系，从而为梳栉、槽针和针芯运动装置的安装调试和结构设计提供参考。

Analyzing on loop-forming motions and knitting devices of warp knitting machines

The key in the research and development of the warp knitting machine lies in designing its knitting devices.This paper analyzed the primary loop-forming motions of slot needle type warp knitting machine and related requirement concerning the knitting devices such as guide bars,slot needles and tongues,including the types and laws of motions of individual knitting devices at the end.Model selection under the conditions of less guide bars was discussed with practical cases,and the match of guide bars and slot needles of the machine and the motion relations of the slot needle hook and the tongue when closing were determined.The phase relationship between guide bar,slot needle and tongue was studied based on their matching motions,thus laying a foundation for installation,adjusting and structual design of the motional devices including guide bars,slot needles and tongues.
