摘要
为减少纺纱断头,提高环锭纺纺纱生产效率,研发了一种面向环锭纺系统的纺纱张力在线检测装置,将力传感器和位移传感器嵌入导纱板,再通过计算机信号数据采集处理系统,对导纱钩处的动态受力情况进行在线检测,将即时动态监测与物理-数学方程求解相结合,以牵伸-加捻-卷绕等纺纱机构的力学模型和数学方程即时求解纺纱张力的动态变化规律。结果表明:纲领板一次升降过程中,加捻段纺纱张力、气圈顶部和底部张力、卷绕张力均呈现由小到大再到小的周期性变化;小纱张力最大值比中纱增加了12.6%,大纱张力最大值比中纱增加了10.6%。
In order to reduce the yarn breakage and improve the ring spinning production efficiency,an online detecting device for detection on spinning tension of ring spinning was developed with the force sensor and displacement sensor embedded in the guide plate.The dynamic stress at the guide wire was detected by the computer signal data acquisition and processing system.Combined with physical-mathematical equations,the dynamic variation of spinning tension was solved according to the drawing-twisting-winding mechanical models and mathematical equations.The results show that when program board is lifted and droped once,spinning tension of twisting area,the top and bottom ballooning tension and the winding tension periodically vary from small to large and then to small.Compared with the maximum tension of middle yarn,that of small yarn increases by 12.6%,and big yarn increases by 10.6%.
