The funnel automatic batching machine is one of the most crucial production stages in industrial production. The quality of the batching will directly affect the production quality of the products. The automatic batching process is a multi-input and multi-output process. Each batching production line cooperates in an orderly and coordinated manner, accurately controlling the material level and quantity. During the entire batching production process, the main material and auxiliary material are combined in proportion, and the material is accurately measured and conveyed by the screw scale and then transported by the screw conveyor. The PLC monitors the entire conveying and batching process and displays and alerts for system faults. The speed of the screw conveyor is achieved by transmitting signals to the frequency converter. 

The feeding system is mainly composed of the storage bin, weighing bin, intermediate bin, mixing bin, bin wall vibrator, feeding vibrator, discharging vibrator, and screw conveyor, as well as the mixer, etc. The motor controls each vibrator and the mixer; the solenoid valve controls the intermediate bin door and the discharging door of the mixing bin. The scale frame is suspended by two Weighing modules. When the material on the screw passes above the scale frame, the weight of the material presses on the weighing module, and the output signal of the weighing module is proportional to the weight of the material. It is converted into the average weight of the material per unit length (kilograms/meter). At the same time, the speed module measures the current screw running speed (meters/second), and thus calculates the instantaneous flow rate of the material on the screw (kilograms/second). These values are accumulated to form the total material conveying volume. 

When the Batching system is powered on, the motor drives the screw to operate, and the microprocessor controls the motor speed. The batching is carried out from the hopper to the discharge area, then conveyed by the screw to the weighing area. The screw scale will weigh the material on the screw. The weighing sensor outputs a voltage signal according to the pressure of the material, which is amplified and converted into a measurement level signal, which is proportional to the weight of the material. Then the signal is sent to the upper computer interface and converted into a flow signal. The flow value is displayed on the current upper computer and sent to the PLC. The PLC compares and calculates with the given batching value set by the upper computer. This control quantity is transmitted to the frequency converter to change the output value of the frequency converter to complete the speed control. Adjust the given quantity to be the same as the set value to complete the batching process.
