The automatic filling machine can observe the weighing data through the meter head, in addition the profibus-DP bus transmits the weighing data to the PLC, which reduces the errors caused by interfering signals, transmission or conversion, and ensures the filling accuracy in production. Communicate with PLC through MPI interface, give all kinds of control parameters, control instructions, control the action of PLC; read the status information of PLC for the screen real-time dynamic display of the process of equipment status, weighing data, alarm information. The computer also has the functions of system security setting, filling management, production report inquiry and printing, scale zero calibration and scale parameter setting.

The liquid filling machine will send the empty barrel to the filling position and align the barrel mouth with the spray gun mouth. When the detection spray gun is in place, the bottom valve will be opened and the nitrogen filling valve will start to fill the dry nitrogen into the barrel through the filling mouth, so that the air in the barrel will be replaced by nitrogen, and the drying of the inner wall of the barrel can be accelerated to ensure the safety of filling. When filling with nitrogen, it should be ensured that the air in the container is completely replaced, and the specific amount of nitrogen can be adjusted by the controller time.

The weighing and filling machine is mainly composed of four main parts: transfer device, filling device, suction and sealing device and detection electronic scale device. Integrate informationization accessory equipment, such as printers, scanning guns, RFID and other information identification equipment, to give the material into the weighing and dispensing process of identifiable information. Adopt CS control management server as the server to manage the whole filling. The industrial Ethernet is used as a network to connect the operating stations of each process. An operator station is placed at each process and connected to each process equipment. Functions of each station are realized by the operator station.

Weighing Liquid Filling Machine provides filling throughput by gravity or by using a pump to fill, moving continuously through different filling, capping, etc. It is a complete set of automated equipment for weighing and filling control by using high-precision electronic scale measuring device, electrical control management and visualization man-machine software configuration. The weight and filling control of the material loaded into the container is carried out through the monitoring system and the PLC program, thus realizing precise metering and filling.

Liquid filling machine all by the full computer filling, feeding, discharging, replenishment control touch screen control, control system can control multiple weighing and filling machine filling operations at the same time, the reaction tank can be formulated several to dozens of materials, can be displayed at the same time the dosage process and print the name of each material, quality, total mass, cycle time, formulas, daily reports, monthly reports and so on.

The automatic filling machine adopts Siemens S7300 series and ET200 module to control the filling according to a certain ratio, and at the same time, it gives the discharging system according to the information of the material level of each material reaction tank. According to the weight and chemical composition of the raw materials for proportion filling control. Adopting two-stage adjustable filling methods for large and small materials, the filling machine improves the accuracy and production capacity; equipped with top barrel automatic protection function for automatic lifting of the filling gun when the gun is not inserted into the barrel and not performing filling; the filling gun is professionally designed for ink, and it is easy to dismantle and install it quickly with bare hands and convenient for maintenance.

The weighing and filling machine adopts computerized automatic control of weighing, double-speed filling (fast filling at the beginning and slow filling when the electronic scale is close to the target amount) to ensure the filling accuracy, and adopts automatic quantitative filling to control the filling operation of raw materials in barrels. The automatic filling machine is a comprehensive automatic filling control system integrating computerized production process control and data management with weighing and filling, filling control and discharge. Air source interface: User provides 12mm gas pipe connector for quick connector connection

The explosion-proof gas cylinder scale receives weighing data, cylinder numbers and skin weight values from the upper computer, and based on these data, it sends signals allowing for filling, target filling volume, tolerance value and early alarm value to the PLC controller. The PLC controller, upon receiving the signal allowing for filling, automatically performs operations such as removing the skin and filling. Before filling, the empty chlorine gas cylinders are placed horizontally on the cylinder scale, the position of the cylinder valve is adjusted, and copper tubes are used to connect the upper and lower bottle valves of the cylinders to the exhaust pipes for discharging waste gas from the storage tank and the liquid chlorine outlet pipe of the storage tank. During the operation, the exhaust valve at the top of the cylinder is opened first to exhaust, and then the liquid chlorine outlet valve of the storage tank is opened to carry out the filling process. After the cylinder is filled, it is lifted away by a crane, and then the second cylinder is filled according to the procedure. After the liquid chlorine in the liquid chlorine storage tank is emptied, the liquid chlorine is switched back to the empty tank, and the production and filling processes are alternated.
