摘要: 为了解决传统织针机械编织效率过低,能耗较高的问题,基于提花圆机技术,提出新的磁悬浮式驱动织针原理,通过对磁悬浮驱动织针运动轨迹的分析及仿真,得出织针运动的位移、速度以及加速度曲线,并通过对系统建模,得到电磁、永磁织针之间的作用力关系。设计并完善驱动装置,基于实际E24针织提花机研究对象,验证磁悬浮驱动织针装置的编织效果。实验证明:基于新型磁悬浮方式织针编织,编织效率比传统方式提高近17%左右,同时编织工艺和轨迹得到优化。关键词: 磁悬浮式驱动织针;选针关键技术;编织机构;以电代机;试验模型

Abstract: In order to solve the problem of weaving efficiency is too low, and the energy consumption is too high in traditional knitting machine, based on the technology of jacquard machine, the paper propose the new principle of magnetic suspension driving knitting needle. Through motion trace analysis and simulation of magnetic suspension driving knitting needle, obtain the needle’s movement displacement, velocity and acceleration curves, also, through system modeling, get the force relationship between electromagnetic and permanent needle. Design and improve the driving device, based on actual jacquard machine E24 as research object, verifying the weaving performance of magnetic needle device. Experiment has proved: needle model based on new magnetic driving, the weaving efficiency has improved nearly 17%, at the same time, knitting technology and trajectory is optimized.
