摘要: 为改善梳栉横移运动,减小横移冲击,通过分析梳栉横移运动的工艺特性,运用机械运动学理论,选用适合高速凸轮机构的组合正弦加速度运动规律作为梳栉横移驱动曲线,研究影响横移运动特征值的4个因素:织针针距、横移针距数、经编机主轴转速和横移允许主轴转角。分析结果表明,可通过增大横移允许主轴转角的方法来优化横移运动,即在确保横移安全可靠的条件下导纱针横移提早起始点,延后结束点,增长实际横移时间,从而显著改善高速经编机梳栉横移的运动性能。

Abstract: The goal of this research is to improve shogging motion characteristic of the guide bar and reduce the impaction of shogging. The combined sine acceleration movement rule is chosen as the shogging motion curve of guide bar under the motion theory of machines and mechanisms by analyzing the motion characteristics of shogging movement of guide bar, and it is found that four factors influencing the shogging movement, that is, needle gauge, number of shogging needle space, the main shaft speed of warp knitting machine, and allowed shogging period,that is to say, to extend the shogging time under the condition of ensuring the safety and reliability of shogging movement with making the starting time earlier and postponing the ending time, the shogging movement performance can obviously be improved.
