The electronic canned Filling machine is coordinated and controlled by a programmable controller (PLC) for the tasks of bucket positioning, roller conveyor operation, weighing and filling, and material storage. It is controlled in various modes such as manual and automatic through a human-machine interface, eliminating the need for numerous buttons and switches on the panel, which simplifies the operation. At the same time, there are many status displays on the touch screen, facilitating the operator's understanding of the system's operation status. The Liquid filling machine selects high-precision Weighing modules and highly stable weighing instruments to control the filling process, fully meeting the system's accuracy and speed requirements. The Filling system control methods include manual and automatic. In manual mode, it can achieve single-unit filling, separate operation of the roller conveyor, and movement of the spray gun. The filling system is also an integrated high-tech product combining machinery, electricity, optics, and gas, forming a machine that cooperates with each other to automatically complete drying, disinfection, cooling, as well as bottle sorting, cap sorting, cap insertion, filling, and capping processes. Comprehensive monitoring of the operation status of related equipment improves the safety operation coefficient, and collects and processes various data and exchanges them with the server to achieve data sharing. The monitoring management layer is processed centrally by computer technology, network technology, database management system, and software technology, concentrating the filling data and monitoring information.

The liquid filling machine includes a machine base, fixedly installed on the machine, a movable frame that slides up and down on the base, a handwheel cylinder fixedly installed on the movable frame, the filling head is clamped with the moving part of the cylinder, the valve is fixedly installed on the base, the connecting pipe and weighing mechanism are used to weigh the filling quality, the liquid level sensor is located on both sides of the transparent container and fixedly connected to the machine base to detect the liquid level in the container. By adjusting the height of the movable frame with the handwheel, the cylinder drives the filling head to move downward, the material passes through the valve and the connecting pipe into the filling head, then enters the container, drips onto the support net, passes through the support net into the box, and is guided by the guide block and flows into the pipeline, and enters the collection box, reducing the detection error of the weighing instrument. At the same time, the liquid level sensor detects the highest liquid level in the container.

The weighing filling machine is controlled by the PLC programmable controller. When the container is fed in, the motor-driven roller conveyor operates simultaneously. The photoelectric sensor detects the signal when passing through a container and stops the motor. The photoelectric sensor detects the signal when the container reaches the filling position and controls the cylinder to stop. The Electronic scale senses the empty bucket reaching the electronic scale platform and is controlled by the PLC to stop the motor-driven roller and automatically zero the scale. The filling valve is driven by the stepper motor to descend to the lower limit position and sends a signal from the travel switch. The PLC controls the filling valve to fully open for filling. When the set value is reached, the electromagnetic valve acts, the filling valve partially opens for filling, and the filling process is carried out while the stepper motor drives the filling valve to rise at a pre-set speed through the screw; when the filling requirements are met, the filling valve closes, reaches the upper limit position of the travel switch, stops, and sends a signal. The PLC simultaneously controls the motor and the scale body roller conveyor to operate, and the finished product is output, the empty container is fed in, completing one filling process.
