The batching system is based on the existing measurement and control equipment such as electronic belt scales, screw reamer pumps, nuclear scales, etc. The corresponding Lon Works nodes are connected to the inputs of these existing batching control equipment, and the non-LonWorks fieldbus equipment is integrated into the fieldbus to form a fieldbus-based control system. The nodes used here mainly include: PCLTA-10 adapter card and PC and connect to form the Lon Works network management and monitoring node; Lon Works/4-20mA conversion node will comply with the DDZ-Ⅲ standard analog signal 4-20mA control equipment integrated into the fieldbus; Lon Works/485/232 conversion node will be the digital interface control equipment integrated into the fieldbus; Lon Works/485/232 conversion node will be the digital interface control equipment integrated into the fieldbus; Lon Works/485/232 conversion node will be the digital interface control equipment integrated into the fieldbus. The Lon Works/485/232 converter node integrates digital interface control devices into the fieldbus; the monitoring and control of switching quantities is accomplished by the I/O modules of the Lon Works control node.

The automatic filling machine production line uses SCADA filling as the platform and integrates computer identification technology, printing technology, automatic control technology, and information technology to form intelligent filling to meet customers' requirements for automation, informatization, and intelligence in the filling process.

The weighing management system uses barcode/RFID electronic label technology, combined with ERP visual database software, to form an all-round tracking system from production, warehousing, inventory, transfer, and outbound delivery.The system consists of two parts: ERP barcode data management and handheld client management.

The automatic batching system is equipped with an automation system with MODBUS as the core and weighing batching as the main means to achieve fully automated control of the liquid preparation and mixing processes.

The automatic filling machine automatically completes six major processes of feeding, weighing, bag supply, bag clamping, filling and sewing, and the working process is mainly divided into two parallel routes to complete. Adopting self-weight feeding method, the device has simple structure, safe and reliable action, good versatility, high feeding precision and high speed. The three-stroke feeding mechanism is located at the top of the upper frame, and the vibrating feeder is located at the appropriate position between the three-stroke feeding mechanism and the weighing part, the joint use of the two mechanisms will ensure the feeding accuracy and improve the filling accuracy. The weighing part is mainly composed of weighing hopper body, movable door body, opening and closing door cylinder, load cell and metering module support.

Feeding system through the negative pressure in turn the raw materials into the hopper scale, weighing and transferred to the hopper, to be timed to time, the PLC gives a control signal to close the feeding motor, open the hopper scale discharge port, the raw materials will be sent to the high mixing tank, at this time, the high mixing motor to start. Raw materials in the high mixing tank through the stirring temperature, until the purpose of mixing (synthesis).
