精确自动化包装机料斗门的设计

The design of precise automated packaging machine material flood gate

为了解决固体粉末状产品在自动化包装过程中所遇到的重量检测不准确以及由单片机所发出的控制信号不及时等问题,作者将步进电机在自动化包装机料斗门中的应用专门拿出来加以研究。提出了采用BGC技术精确测量和P89C54单片机以及SI-7230M等控制设备驱动步进电机控制料斗门的方案,建立了测量出的数字信号Di与步进电机转动角度θ之间的函数关系。

In order to solve the solid powdery product the weight measured which meets in the automated packing process as well as which sends out the control signal is inferior to wait and the question by the monolithic integrated circuit, The author step machine specially will put out in the automated pack aging machine material flood gate application performs to study. Proposed the plan of uses BGC control device and P89C54 monolithic integrated circuit and SI-7230M act. to control material flood gate, established the functionalrelation between.the digital signal Di and the electrical mach（nery rotation angle θ.
