【摘要】 胶印印刷中水量供应的多少对印刷质量影响巨大,如何保证供给印版足够而均匀的水量,使印刷质量达到最佳效果的同时且把供水量控制在最小程度,是胶印技术中的一个关键问题。针对此问题,文章设计了红外水量检测装置来对印版表面水量进行数据采集,并设计了水量调节机械执行机构和调节的控制模块,经微控制芯片处理后,控制步进电机驱动并改变水斗辊的转速,从而实现了胶印水量在线自动调节,弥补了印刷工人凭经验调节带来的各种不稳定因素。更多还原

【Abstract】 The damping feed setting does vital influence on the prints’ quality in offset prints.At present,the key problem in printing techniques is how to ensure the damping feed enough and uniformed,at meantime make the print quality perfect with the least quantity of damping.According to this problem,design the infrared damping feed testing structure to collect dates of damping feed on the form surface,and design the mechanical setting and operating module.These dates are treated by microcomputer and passed to control the step motor to drive and change the rotational speed of the water fountain roller,so that it can set the damping feed automatically with real-time testing.This system in the thesis can make up recover the instable factors from the man-made setting by experiences.更多还原
