摘要
为解决高速打印过程中纸张张力波动影响打印质量的问题,设计并实现一种高精度张力控制机构。该机构采用电阻应变式传感器监测纸张张力变化,通过比例-积分(Proportion Integration,PI)控制算法处理张力偏差数据,驱动无刷直流电机调整卷纸轴转速,形成闭环控制系统。实验表明,该张力控制机构在2.0 m·s^(-1)的打印速度下,张力稳定度为0.94 N,控制精度为±1.42 N,系统响应时间为13.5 ms,每小时张力漂移为1.87%,可满足高速打印工况需求,有效提升打印质量。
To address the issue of paper tension fluctuations during high-speed printing that affect print quality,this article designs and implements a high-precision tension control mechanism.This mechanism uses resistive strain sensors to monitor changes in paper tension,processes tension deviation data through a Proportion Integration(PI)control algorithm,and drives a brushless Direct Current motor to adjust the rotational speed of the paper reel shaft,forming a closed-loop control system.Experiments show that at a printing speed of 2.0 m·s^(-1),the tension stability of this tension control mechanism is 0.94 N,the control accuracy is±1.42 N,the system response time is 13.5 ms,and the tension drift per hour is 1.87%,meeting the requirements of high-speed printing conditions and effectively improving print quality.
