塑料包装物撕带自动供给控制系统的设计

Design of Automatic Provision Control System for Plastic Wrapper

介绍了一种电气传动方式的包装物撕带自动供给控制系统,该系统采用永磁式直流伺服电机为驱动源,驱动撕带轮的轴转动,向包装机供给撕带.运用脉冲宽度调制(PWM)技术设计了高效率的电机驱动电路,驱动伺服机转动.采用单片机为核心芯片,运用闭环控制技术,实现了对伺服机运行的控制,从而保证了撕带按机器包装的适时需求平稳供应.

The paper introduces the design of wrapper automatic provision control system using electric transmission mode.The system provides wrapper to the machine with the permanent magnetic DC servo electromotor used as drive source to make the wrapper axis running.The PWM technology is applied to design high efficient drive current.With the single chip processor as the core,the system in the closed-loop technology is used to control the servo electromotor to assure the wrapper is provided placidly according to the...
