The Electronic scale Filling machine is composed of three cylinders or oil cylinders (upper cylinder, lower cylinder, control cylinder), two one-way filling valves (upper filling valve, lower filling valve), one quantitative cylinder and pipeline, and other accessories. The storage tank is located at a high position and is connected to the upper filling valve through a pipeline. The upper filling valve is divided into upper and lower parts by an elastic membrane, which can separate the material from the moving parts of the upper cylinder to ensure the hygiene of the material. The lower part is the main body of the one-way filling valve with spring reset, which is connected to the storage tank and the quantitative cylinder. The upper part of the filling valve is equipped with an upper cylinder, and the piston rod of the cylinder controls the opening of the upper filling valve through the action of an elastic membrane. There is also a control cylinder installed on the upper part of the upper cylinder, which can determine the stroke of the upper cylinder piston rod in two ways, and then control the opening size of the upper filling valve. The core process of an automatic filling machine lies in two filling steps: pre filling and supplementary filling. The empty cans that have been peeled are sent by the Filling system to the bottom of the pre filling area for pre filling. The amount of pre filling is set in advance in the PLC, and the filling screw is driven by the same service motor according to the pulse command of the PLC for filling. After the pre filling is completed, the filling system sends the can to the pre filling weighing station, where it is weighed by the weighing module (usually leaving about 1% -5% of the target weight space for supplementary filling during pre filling). The actual value of the weight is fed back to the PLC, which calculates the amount that needs to be supplemented (supplementary filling amount=target weight - actual pre filling weighing value). The filling system then sends the can to the supplementary filling position to begin supplementary filling. After the supplementary filling is completed, it is sent by the filling system to the supplementary filling weighing module for testing. If the weight is qualified, the filling is completed and the can is discharged; If there is a significant difference from the target value, the filling system will send it to supplementary filling for a second time until the weight is qualified to complete the filling and release the can.

The Liquid filling machine is fixed and installed on the machine by bolts, and the moving frame slides up and down on bracket 2; The handwheel adopts a combination of a grip and a rod. The grip rotates on the bracket, and the rod passes through the moving frame and is connected to its thread. The grip is integrated with the rod, so that rotating the grip can drive the moving frame up and down through the rod; The cylinder is fixed on the moving frame by bolts; The filling head is connected to the moving part of the cylinder by a buckle, and the cylinder drives it to move up and down; The valve is fixed on the bracket by bolts, and the connecting pipe is connected to one end of the valve and the other end of the filling head; The weighing mechanism is used to weigh the quality of the filling. It adopts a frame support net that is fixed and installed at the upper end of the frame through welding. A transparent container is placed on the support net, which is bonded with a rubber pad to increase the friction between the support net and the container; The aggregate frame is fixedly connected to the machine by bolt connection, and there is a cavity for storing liquid inside. The bottom of the cavity is equipped with an emptying pipe for emptying the liquid inside; The weighing instrument is connected to the gap between its upper end and the frame, and to the gap between its lower end and the aggregate frame. It is fixedly connected to the machine through a bracket to detect the liquid level inside the container. By adjusting the height of the mobile frame through the handwheel, the cylinder drives the filling head to move the material downwards through the valve and connecting pipe into the filling head. After entering the container, the liquid drips onto the support net and enters the frame through the support net. It is on the guide block and flows towards the pipeline under the action of the guide block, entering the aggregate frame to reduce the detection error of the weighing instrument. At the same time, the liquid level sensor detects the highest liquid level in the container.
