How does a fully automatic weighing and packaging machine work

The working principle of the automatic weighing and packaging machine: As the name suggests, a packaging machine is a device used for packaging products. Packaging has multiple uses, among which the most important one is to wrap products with packaging film or bags, which have the effects of moisture-proofing, dust-proofing, wear resistance and beauty.

How does an automatic weighing and packaging machine work?

When using the fully automatic packaging machine, the power switch must be turned on. The power selection switch indicates vacuum during vacuum sealing and vacuum filling and sealing during vacuum filling.

2. Put the plastic bag containing the items into the vacuum chamber and neatly place the bag opening on the heat seal strip.

When the lid is pressed, the exhaust light on the panel will light up, the vacuum pump will start, and the lid will be automatically sucked in. The vacuum knob can be adjusted to the vacuum degree according to the packaging requirements. When adjusting, visually scale from low to high, with a small amplitude.

4. When the pumping time reaches the set point, the pumping light goes off and the inflation light comes on, indicating that the inflation has started. The inflation knob can be used to adjust the duration of the inflation. If inflation is not needed, switch the power switch to the vacuum position, and the program will automatically enter vacuum packaging with the inflation light going off.

The weighing and packaging machine is mainly composed of a belt feeder, a self-unloading weighing hopper, a bag collection hopper, an electrical control unit and other components, and has excellent performance. The belt feeder is composed of material layer doors, conveyor belts, open/close doors, etc. It is controlled by using a two-speed motor to control the conveying speed of the conveyor belt and the height of the material layer at the outlet.

The self-unloading weighing bucket is mainly connected to the weighing sensor through connecting bearings or cylindrical pins, so the weight and load of the weighing bucket can be accurately displayed on the weighing machine. The discharge door at the bottom of the hopper of the automatic weighing and packaging machine is usually pushed by a single cylinder, which can maintain the relative balance of the weighing hopper throughout the working process.
