The quantitative feeder mainly consists of two parts: electrical control and mechanical components. 

I. Composition Structure  quantitative feeder

1. Electrical Control Part Mainly includes: control cabinet (control box), weighing control instrument, frequency converter, load cell, speed sensor, rotary encoder, etc.

  2. Mechanical Part Mainly includes: drive unit, weighing body, weighing base, driving roller, driven roller, endless belt, belt load measurement device, belt speed measurement device, belt tensioning device, cleaning device, carrying idler, distributor, dust hood,etc. https://www.zhitianmeteringequipment.com/product/high-definition-dynamic-checking-weigher

II. Working Principle Material Conveyance:  quantitative feeder

During normal operation, the endless belt continuously pulls material from the distributor. Signal Acquisition: When material passes the belt load detection device, the load cell collects the belt load signal, and the speed sensor collects the belt speed signal, both of which are sent to the weighing control unit. Flow Calculation: The control unit integrates the belt load signal and belt speed signal to calculate the actual material flow rate. Closed-Loop Adjustment: The actual flow rate is compared with the set flow rate to obtain a deviation value; based on the deviation, the frequency converter’s output frequency is adjusted in real time to change the motor speed and belt speed, thereby regulating the material flow rate and ensuring the actual flow rate stably tracks the set value, achieving continuous and precise quantitative feeding. https://www.zhitianmeteringequipment.com/product/high-definition-dynamic-checking-weigher     quantitative feeder
