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 %。 This paper introduces a kind of automatic control circuit of various parts of film cutting machine commonly used in trademark production, including the design of eye detection circuit, pulse forming and counting circuit, paper feeding motor control circuit, correcting circuit and setting circuit. The performance index of the system is much better than that of the existing domestic equipment, and exceeds the imported equipment on some indexes. The cutting speed of the system is increased by 10% ~ 20% and the rejection rate is reduced by 20%.
