Automatic filling machine can be adjusted by changing the speed of the frequency converter gear filling volume size, weighing controller pulse signal through the filling valve to the filling container dispensing liquid, control the solenoid valve switch on and off, drive the implementation of the lever drive to make the filling valve within the conical spool open or close, to achieve the liquid circuit intermittent opening and closing, showing the weighing filling system of the entire filling control process. The automatic filling machine by the stepper motor, gear pump filling head, conveyor belt and electrical control box, the electrical part mainly includes stepper motor drive power supply, positioning solenoid valve, counter, cylinder filling head, conveyor motor and the corresponding control circuit, filling machine mechanism through the variable speed deceleration to stay in the E stepper motor output shaft and the ruler wheel pump drive shaft is connected to the stepper motor can be used as a power source of the filling liquid, but also The stepper motor can be used as a power source for filling liquid, and also can control the number of steps of the stepper motor to achieve precise control of the number of revolutions of the gear pump so as to realize the purpose of precise measurement. Adopting PLC two-stage automatic filling method, the net weight/gross weight two kinds of filling methods are free to choose, and the filling target volume is set freely, which is convenient for various weight packages. Through the microprocessor's calculation and analysis, it is transformed into electric signal or other required form of information output according to a certain law, in order to meet the requirements of information transmission, processing, storage, display, recording and control.

Programmed and controlled according to the process requirements, the weighing system and PLC program control the weight and flow of the material loaded into the weighing drum, thus realizing accurate measurement and batching. With strong stability and high cost performance, it can provide accurate measurement data and control means for production control and management in various industrial sites. Filling through the time and unit time flow rate to determine by the programmable controller (PLC) control to determine, through the human-machine interface - touch screen monitoring of the operating state, can be modified online operating parameters. Through the weight transmitter transformed into 4~20mA current as the input signal for system display and control, the current weight of the raw material barrel as the starting weight setting value, and through the display instrument or DCS system set as the target dosing value, when the weighing module detects the weight in the canned barrel rises to a certain value, at this time, the output current and the weight value is basically a linear relationship, in order to ensure the accuracy of each point, the filling In order to ensure the accuracy of each point, the liquid level signal of the filling barrel is used as the control signal of the feeding valve for the automatic adjustment of the liquid level parameter, so that the whole automatic filling machine realizes the automatic adjustment function of the continuous production process. The weighing system integrates weight information collection, amplification, transformation, transmission, processing and display, and controls the sensors, relays, switches and solenoid valves through PLC program. It draws on the advanced technology and techniques, and combines with its own long-accumulated experience to integrate the inventory management, filling management, filling and weighing, process control and product traceability, etc., and adopts the barcode (two-dimensional code / RFID) Identification, wireless transmission, automatic weighing, PLC control, electromechanical, computer interface and other automation technologies, independent development and completion of intelligent filling weighing and inventory management system, to prevent the filling of wrong materials, to ensure the accuracy of the weighing, to ensure the accuracy of the filling process, so that each batch of filling data are recorded and traceable, and in the raw materials out of the warehouse to follow the principle of first-in, first-out, an effective solution to the waste of raw materials.
