一种基于变频器PID控制的卷料匀拉力输送装置的应用

A kind of coil uniform tension conveying installation based on inverter PID control

通过对卷料输送能力和材料拉伸强度的分析,应用变频器内置的PID控制功能,设计了一种卷料匀拉力输送装置,该装置采用变频器PID控制、卷心驱动的方式,实时跟踪主驱动线速度,同步精度高,同时保证材料不会因拉伸变形、拉断,图案不失真.该装置已在烟草包装机械上验证,使用方便,性能可靠.

By the analysis of coil conveying capacity and material tensile strength,using the inverter PID control function,a kind of coil uniform tension conveying installation was designed,which concluded inverter PID control and cabbage drive,can track the coil speed real-time of the main drive with high synchronization accuracy,and has no tensile deformation,pattern distortion.The equipment has been verified in tobacco packaging machinery,which shows that it is easily operated,high reliabilabe.
