摘　　要：随着纱线生产自动化的不断提高,电子牵伸型细纱机以其调整的便捷、工艺的上限突破以及品种的多适应性等优点,逐步被更多的纱线生产厂家所认可。电子牵伸系统在采用伺服控制方案后,针对传统的细纱机锭带传动造成的捻度波动、重负载的扭震的开停车粗细节以及低捻纱的留尾差控制等多个难题有较大的突破,在全流程自动化控制方案下,对捻度和牵伸倍数的稳定性也有着较好的均调控制。With the continuous improvement of yarn production automation,electronic drafting spinning frame with its convenient adjustment,eakthrough of the upper limit of technology,and the multiple adaptability of varieties,gradually recognized by more right yarn manufacturers.When electronic draft system use adopting servo control scheme,twist fluctuation caused by traditional spinning frame,heavy load torsional vibration starting and stopping details and there are great breakthroughs in the tail keeping control of low twist yarn.Under the whole process automation control scheme,it also has a good uniform control over the stability of twist and draft multiple.
