定量给料机的工作原理
螺旋给料机把经过的物料通过称重桥架进行检测重量，以确定胶带上的物料重量，装在尾部的数字式测速传感器，连续测量给料机的运行速度，该速度传感器的脉冲输出正比于给料机的速度，速度信号和重量信号一起送入给料机控制器，控制器中的微处理器进行处理，产生并显示累计量/瞬时流量.该流量与设定流量进行比较，由控制仪表输出信号控制变频器改变给料机的驱动速度，使给料机上的物料流量发生变化，接近并保持在所设定的给料流量，从而实现定量给料的要求。Working principles
Screw feeder through the material by weighing bridge test weight, to determine material weight on the tape, in a digital speed measuring sensor, at the end of the continuous measurement of feeder speed, the speed sensor pulse output is proportional to the speed of the feeder, speed signals and weight together into the feeder controller, the controller of the microprocessor for processing, producing and displays a cumulative amount/instantaneous flow. Compared with the traffic and set up flow, is controlled by a control instrument output signal frequency converter to change feeder driving speed, the feeding machine of material flow changes, close to set and maintain in feed flow, so as to realize the quantitative feeding requirements.
