Research on gravure wallpaper printing machine reduce error volatility and synchronous control

针对凹版壁纸印刷过程中由于纸张在烘干和冷却时伸缩产生的误差累积,而传统同步控制系统在消除该误差时由于机械波动及检测误差容易引起速度较大的波动,通过对误差变化规律的分析和对误差补偿方法的算法设计,设计了一种以DSP芯片TMS320F2812为核心的套准系统。利用均值误差和脉冲补偿的方法来减小由于机械波动及检测误差带来的影响,进而减小误差调整时印刷速度波动大引起的套准精度降低,并用MATLAB进行了仿真,通过对同步控制系统的改进,减小了误差调整时引起的波动,提高了凹版壁纸印刷同步控制系统的稳定性和印刷精度,有较高的实用价值。

In the process of the gravure wallpaper, the errors accumulated due to the paper tension when drying, but the traditional synchronous control system to eliminate the errors due to the mechanical wave and the measurement error is easy to cause the velocity fluctuations. In this paper, the errors accumulated are analyzed and the synchronization control system are improved by algorithm design, design a quasi system based on the DSP chip TMS320F2812 as the core set. Using mean error and pulse compensation to reduce the impact of mechanical wave and the detection error, and then reduce the reduced printing registration caused by printing speed fluctuation when error adjustment, and simulation with MATLAB, Through the improvement of the synchronous control system, reduce the fluctuation caused by error adjustment and improves the stability of the system,have high practical value.
