摘　　要：针对我国地毯织造技术基础研究相对薄弱的现状,为给平割平圈地毯织机设计提供更多的理论指导,首先参考时间圆图设计方法和一般割绒地毯织机的工艺要求,提出平割平圈地毯织机簇绒针和成圈钩组件的运动时序关系。然后通过对连续圈绒、割绒和圈割绒交替簇绒时的成圈工艺分析,指出成圈绒时簧片的动作稍超前于成圈钩的远止点时刻,成割绒时簧片动作最晚时刻在成圈钩的远止点时刻,得出平割平圈地毯织机的运动时序关系图。由于平割平圈地毯织机的簧片运动由电气控制实现,独立于由主轴驱动的针、钩、刀的运动体系,因此,运动时序的分析和设计可为成圈机构的机械设计、电气控制系统的设计提供理论参考。The basic research on carpet tufting technology is relativelly weak in China, and the guiding ideology and basic theory of tufting machine design were provided. The sequential relation of needle and looper in level-cut-loop （LCL） tufting machine was proposed according to the design method of phase circle and the technological requirements of general cut carpet tufting machine. The sequence chart of LCL carpet tufting machine was acquired by studying the loop-forming process under the circumstances in continuous loop pile, continuous cut pile and alternating loop and cut pile. It is showed that the latch should close upon the looper at the time which is slightly ahead the looper’s far stop time when a loop pile is tufted, and separate from the looper at leastbefore the looper’s far stop time when a cut pile is tufted. Owing to the motion of latch in the LCL carpet tufting machine is electrically controlled, and it is independent from the spindle drive movement system of needle, looper and knife, and the time sequence analysis and design provides the foundation for the machine design of loop-forming mechanism and the electrical design of control system.
