First, the working principle
Loss-in-weight weighing mechanism
The equipment monitors the weight change of the hopper in real time through the load cell, calculates the actual feeding amount according to the weight reduction rate per unit time, compares it with the preset target flow, and adjusts the belt speed through PID closed-loop control to ensure the feeding accuracy.
Belt conveyor structure
The material is conveyed to the downstream equipment at a constant speed through the belt, and the belt speed is dynamically adjusted by the inverter to achieve precise control of the flow.Second, the structure of the compositionCore componentsWeighing system: high-precision sensors (such as Ronan brand) provide real-time feedback of weight data.
Belt conveyor: The belt structure can adjust the speed to adapt to the characteristics of different materials.Control system: controller with integrated PID algorithm, support automatic/manual switching.
Accessibility
Hopper design: strong sealing to prevent dust leakage, some models are equipped with agitation device to improve fluidity.Feeding mechanism: automatically detects the material level and triggers the feeding signal to ensure continuous feeding
