摘　　要：根据提花机的工作原理以及纺织织物形成的原理,指出提花机开口机构是织机的主运动机构之一,强调了开口机构的作用。通过对目前凸轮式开口机构提刀的位移曲线、速度曲线、加速度曲线和跃度曲线的运动规律进行分析,研究凸轮式开口机构不能满足高速运转的缺点及其原因,并在满足相同的织机主轴转速条件和满足相同的开口量条件下,提出另一种开口机构——连杆机构式开口机构。建立组合连杆机构的运动模型,采用复数矢量分析法计算该连杆机构式开口机构提刀位移曲线、速度曲线、加速度曲线和跃度曲线的变化规律,并把此运动规律与凸轮式开口机构的运动规律进行对比分析,得到了连杆机构式开口机构能满足高速运转的结论,并确定以连杆机构式开口机构代替凸轮式开口机构的传动机构。According to the operational principle of jacquard machine and forming theory of the woven fabric, it points out that shedding mechanism of the jacquard machine is one of the main mechanisms in primary motion with an emphasis on the role of the shedding mechanism. By an analyses on the regular pattern of the movements involving the displacement curve, velocity curve, acceleration curve and jump curves of the cutter in current cam-type shedding mechanism, we try to explore the shortcoming and reasons causing the cam-type shedding mechanism fails to satisfy high-speed operation. And put forward an alternative shedding mechanism-shedding mechanism with linkage assembly while the conditions of same loom spindle speed and same amount of shedding are satisfied. The established motion model for the combined link-rod mechanism adopts complex vector analysis to calculate the regular pattern of the variations of displacement curve, velocity curve, acceleration curve and saltus curve of the cutter in the shedding mechanism with linkage assembly. With a comparative analysis of the regular patterns between its motion and the motion of cam-type shedding mechanism. Finally we obtain the conclusion that the shedding mechanism with link-rod assembly can satisfy high-speed operation and decide to replace the transmission mechanism of the cam-type shedding mechanism with the shedding mechanism with linkage assembly.
