胶辊数字中高机的设计

针对印刷机中普通胶辊由于胶辊扰度造成印制品厚薄不均的问题，以中高度法原理为依据，提出了将中高度曲线方程解析成以时间为变量的函数，用单片机计算和控制中高机运动，设计了以单片机、交流伺服控制器、变频器和磨头等构建的一个数字控制系统为核心的胶辊数字中高机。应用结果表明数字中高机可安装在普通车床上实现中高胶辊的加工，且中高曲线和中高度可任意设置，设计简便实用，便于推广。

Design of Digital Crown Rubber Roller Machine

To solve the deficiency of unequal thickness of printing products caused by the deflection of rubber rollerduring printing, a digital crown rubber roller machine system was designed. The machine employed SCM. AC servocontroller. variable-frequency drive and grinding wheelhead etc. As the core of digital control. Based on the crownmethod principle, parsed crown curve equation with time as the variables of the function was proposed. The crownmachine was controlled and calculated by the single-chip microcomputer. Results show that the digital crown machinecan be installed in the ordinary lathe to produce crown rubber roller. and the crown curve and height can be set freely.The design is simple and practical.
