自动膜切机控制电路的研制

Development of Auto Control Circuit of Film Cut Machine

介绍了一种商标生产中常用的膜切机的各部分自动控制电路 ,包括眼点检测电路、脉冲形成及计数电路、走纸电机控制电路、纠偏电路、置位电路等的设计。该系统的性能指标远优于现有的国产设备 ,并且在部分指标上超过了进口设备 ,膜切速度提高了 1 0 %～ 2 0 % ,废品率降低了约 2 0 %。

Various automatic control circuits such as eyespot detection circuit,pulse formation and count circuit,paper feed motor control circuit, bias correction circuit and setting circuit frequently used in trademark production are described.The performance of the system is better than that of the existing domestic devices and even better than the imported equipment in some area,such as 10%~20% faster in speed,20%less in rejected products.
