The metering control system of the liquid Filling machine is Siemens S7-200 PLC, mainly responsible for data reading and display, and issuing relevant operation instructions and parameter settings. For example, when the detection unit discovers a defective bottle, it will immediately start counting with the PLC to accurately calculate the position of the defective bottle at the end of the detection machine, and send a rejection command to control the rejection mechanism to push the defective bottle into the bypass. The Filling system consists of FASH and SDRAM. FLASH is mainly used for storing system program code, and the system reads the system program from FLASH every time it is powered on. SDRAM is a synchronous dynamic random access memory that operates at 3.3V with a bandwidth of 64 bits. SDRAM locks the CPU and RAM together on the same clock, allowing both to share clock cycles simultaneously. SDRAM is based on a dual bank structure, containing two interleaved storage arrays. When the CPU accesses data from one bank or array, the other is prepared for data reading and writing. Through the tight switching of the two storage arrays, the reading efficiency is doubled. The display unit is mainly composed of LCD and LCD controller (S3C2400) touch screen. LCD can display image processing structures in real-time, while touch screens are mainly responsible for controlling PLC systems. The I/O unit is mainly used for input and output control of the system. The system controls the actions of the separation mechanism through the output and input of I/O digital quantities.

The automatic filling scale includes a base. The top left side of the base is fixedly connected to the scale body, and the top center of the scale body is fixedly connected to a fixed seat. The front and rear ends of the fixed seat are both slidably connected to two fixed rods. The fixed rod is located inside the fixed seat and is fixedly connected to an arc-shaped plate at one end. A spring is set on the outer diameter of the fixed rod between the fixed seat and the arc-shaped plate. The other end of the fixed rod is fixedly connected to an installation plate. The side of the installation plate away from the fixed rod is connected to a threaded rod in the middle through hole. The end of the threaded rod away from the installation plate is fixedly connected to a handle ring. The top right side of the base is fixedly connected to a liquid storage tank, and the top of the liquid storage tank is fixedly connected to a support plate. The top right side of the support plate is fixedly connected to The inlet of the pump body is fixedly connected to an outlet pipe, and the outlet of the pump body is fixedly connected to an infusion pipe, The end of the infusion tube far away from the pump body is fixedly connected with an electromagnetic valve. The filling machine machinery uses an electromagnetic valve, and the bottom is fixedly connected with an electronic weighing scale. The liquid outlet on the electronic weighing scale is fixedly connected with a filling gun. The top center of the support plate is fixedly connected with a motor, and the driving end of the motor is fixedly connected with the top of the screw. The outer diameter of the screw is threaded with a slider, and the left side of the slider is fixedly connected with a connecting rod. The left end of the connecting rod is fixedly connected with the right side of the filling gun.
