摘要
重型板式给料机是进行物料输送的机械装置。为了能确保生产量,有效提高作业效率,设计了一种在输送物料的同时能测得物料重量的机械装置。本设计通过在给料机链板立柱上安装电阻应变片,采用全臂电桥进行温度补偿,测得桥式电阻应变片输出电压值。基于LabVIEW软件开发虚拟在线动态测量称重系统,实现全时段在线监测,并进行预警、报警及启、停机保护操作。
Heavy plate type feeder is a mechanical device for material transportation. In order to determine the production capacity and improve the efficiency, an online dynamic weighing system that can weight the material during the transportation process is designed. In this design, the resistance strain gauge is installed on the chain plate pillars of feeder, and full--arm electric bridge is used for temperature compensation, finally, the voltage value of bridge type resistance strain gauge is measured. Base on LabVIEW software, the online dynamic weighing system is developed, and the full--time online monitoring, early warning, alarm and the protection operation of turn on or off can be realized.
