基于PLC控制的壁纸压花装置的改进

Improvement in Wallpaper Embossing Device Based on PLC Control

为提高壁纸压花装置的控制精度,以PLC为控制核心,采用交流伺服电机为驱动,通过气动装置对罗纹辊施加压力,采用高速计数器输入中断实现壁纸压花长度的精确控制,并通过扰动补偿解决压花过程中负载突变带来的转速影响。应用实例表明,改进后的壁纸压花装置有效提高了工作质量,可满足生产线的工艺要求。

In order to upraise the control precision of wallpaper embossing device, efforts have been made to use PLC as the control core, put pressure on watermark roll through pneumatic devices, driven by AC servo motor, and precisely control wallpaper embossing in length by interrupting speed counters, and abolish the effect of sudden loading change on rotation rate by turbulent compensation. The application demonstrates that the improved wallpaper embossing devices effectively raise the working quality and can meet the technical demand in the production line.
