The explosion-proof weighing and Filling machine integrates computer technology, automatic control, communication technology, and weighing technology. The Filling system uses programming software and on-site equipment libraries that comply with the IEC-1131 international standard, providing continuous control, sequential control, and high-level language. The on-site equipment library provides a large amount of commonly used on-site equipment information and functional blocks, which can greatly simplify configuration work and shorten engineering cycles. The Liquid filling machine is equipped with configuration software to complete data acquisition and process control. It supports multiple communication protocols, provides users with various device support, rich and colorful dynamic images, and powerful system functions, making it easy to operate. It has strong scalability and is easier to integrate with other systems, effectively protecting users' investments. The redundant station utilizes two redundant CPUs to improve higher availability and security. According to the principle of choosing between two, the switch automatically switches from the running system to another system when a fault occurs, providing dual power or industrial Ethernet communication modules for each subsystem and combining them. The safe, reliable, and advanced practical system design has chosen a mature and advanced distributed computer control system. Under the premise of centralized information management and scientific operation in the production process, the danger is dispersed and the reliability of the system is improved. Various data on site is collected by PLC and transmitted to the central control room for centralized monitoring and management through high-speed network. The central control room host also transmits control commands to PLC measurement and control terminals through high-speed network to implement decentralized management of each unit.

The automatic filling machine is connected to a stand and a fixed kettle. An explosion-proof control box and a two-stage speed control valve are installed at one end of the stand, and an electronic weighing scale is installed on the stand; A weighing sensor is installed at the lower end of the weighing scale, and the fixed kettle is connected to the control valve through a pipeline; A filter is installed on the pipeline on one side of the fixed kettle, and a cleaning device is installed on the pipeline on the control valve side; There is a weighing instrument installed on the control box, which is a field programmable gate array. The required weight value is set through the human-machine interface, and the human-machine interface module stores the weight value in the synchronous dynamic random storage module through the central processing PLC. The worker places the container on the weighing scale, and the position sensor senses the signal of the container. The signal is transmitted to the central processing PLC through the programmable logic module. The central processing PLC sends instructions to the programmable logic module to control the opening of the control valve. The liquid flows from the fixed kettle through the pipeline through the filter to the control valve and is filled into the container. The weighing sensor transmits the weight value of the container in real time to the central processing PLC through the digital/analog conversion module, and compares it with the set weight value. When the weight value of the container is equal to the set weight value, the central processing PLC sends instructions, and the programmable logic module closes the control valve. After filling is completed, the worker takes out the container filled with materials. Filters can filter impurities in liquids to prevent them from being loaded into containers. Cleaning devices can clean pipelines, and two-stage speed control valves can control the flow rate of liquids at fast or slow speeds.
