摘　　要：为了加快实现转杯纺纱加工工艺柔性化、加工过程数字化、控制模式智能化的目标,介绍了自主构建和研发的数控三通道转杯纺纱系统的组成及其机械系统、驱动系统和伺服控制系统的工作原理;柔性调控成纱结构参数的机制与方法;运用优选的系统运行参数与成纱工艺参数进行验证型纺纱试验;对纱线的结构、力学性能和外观质量进行了测试分析。结果表明:纤维混合比为0.3∶0.35∶0.35、牵伸倍数为1.15、卷绕罗拉与引纱罗拉的速比为1.01时,混纺纱线的强度为9.53 cN/tex、单纱断裂强力变异系数为8.76%、4 mm以上毛羽数量为17.5根/(10 m),具有良好的力学性能和条干均匀性,毛羽较少,强力、单纱断裂强力变异系数和条干均匀度变异系数均达到FZ/T 12001—2015《转杯纺棉本色纱》的二级质量标准。数控三通道转杯纺纱系统不仅能对纱线结构参数进行可控性调控,还能够有效提高成纱质量。In order to accelerate the realization of the goals of flexible rotor spinning process,digitalization of processing process,and intelligent control mode,the CNC three-channel rotary spinning system was constructed and developed independently.The composition of the system was introduced.The working principle of its mechanical system,drive system and servo control system,and the mechanism and method of flexible control of yarn structure parameters were presented.Then,the verified spinning test was carried out by using the optimal system operating parameters and yarn forming process parameters.The structure,mechanical properties and appearance quality of the yarn were tested and analyzed.The results show that when the fiber mixing ratio is 0.3∶0.35∶0.35,the draft ratio is 1.15,and the speed ratio of the winding roller to the guide roller is 1.01,the strength of the blended yarn is 9.53 cN/tex,the coefficient of variation of single yarn breaking strength is 8.76%,and the number of hairiness above 4 mm is 17.5 pieces/(10 m).It has good mechanical properties and evenness,with less hairiness,and the coefficient of variation of strength,single yarn breaking strength and strip evenness all reaches the second-class quality standard of FZ/T 12001-2015"Spinning Cup spun Cotton Grey Yarn".Therefore,the CNC three channel rotor spinning system can not only control the yarn structure parameters,but also effectively improve the yarn quality.
