The automatic reduction Filling machine is based on programmable intelligent modules, industrial control computers, and RS485 fieldbus to achieve signal acquisition, processing, control, and output, forming a cost-effective Weighing system; The Filling system uses a local area network to achieve communication between the on-site monitoring computer and the management computer; The software is developed using VC++with a modular approach. The Siemens PLCS7-300 system is adopted, consisting of weighing module, PLC system, touch screen, alarm system, on-site pressure transformer, solenoid valve and other components. The operation station adopts DELL industrial computer WINXP operating system, and programmable controller is designed for process control such as filling scanning and filling management. Based on relevant database information services, the monitoring interface of the automatic filling production line is installed using Kingview software. The operation interface is simple, applicable and easy to modify, achieving a complete human-machine dialogue state. The filling machine realizes the networked centralized visualization of the liquid filling operation system, achieving the expected filling effect. It globally schedules and controls each link, and calls the GPIO module to control the valve switch based on the current status. Responsible for reading analog information of system connections, such as temperature transmitters, pressure transmitters, etc. Through the Mod bus protocol, read the weighing data information connected to the system, provide embedded database access, and be responsible for caching the values of peripherals for the central control module to call.

The Liquid filling machine is equipped with universal wheels under the base for easy movement. There is a groove on the upper surface of the base, and a weighing scale and a conveyor are installed in the groove from left to right. The conveyor includes a conveyor belt and a support frame. The conveyor belt is installed on the rotating shaft at both ends of the support frame, and the support frame is installed in the groove. The rotating shaft is driven by a motor. The upper surface of the electronic weighing scale is equipped with a roller shaft, and the conveyor is closely attached to the roller shaft, allowing objects on the roller shaft to smoothly move onto the conveyor. A filling bucket is placed above roller shaft 5, and a pushing device is installed on the side of the filling bucket away from the conveyor. The pushing device includes a pushing hydraulic cylinder and a blocking frame. The blocking frame is a U-shaped frame, which is connected to the telescopic end of the pushing hydraulic cylinder. The bottom of the pushing hydraulic cylinder is installed on the base through an installation frame, and the telescopic end of the pushing hydraulic cylinder is horizontally directed towards the filling bucket, so that the filling bucket is placed inside the blocking frame. There is a layer of adhesive pad on the inner wall of the blocking frame to prevent damage to the outer surface of the filling bucket when pushing it. There is a filling gun above the filling barrel, which includes a Feeder. The feeder is installed on the base through a fixed frame, and a first solenoid valve is installed on the lower discharge port of the feeder. A weighing module 9 is installed on the fixed frame below the feeder. A hopper scale is installed above the weighing module, and a second solenoid valve is installed on the discharge port of the hopper scale. The liquid flowing out of the feeder is received by the hopper scale, weighed, and the weight is controlled by the first solenoid valve to ensure the accuracy of filling. Then, the liquid in the hopper scale is transported to the filling bucket for weighing again, ensuring the accuracy of filling and improving production quality through two weighings.
