Switch in the switch power supply, and turn the switch power switch according to the requirement, i.e. the switch power indicator is on. The switch switch of switching power supply is vacuum sealed when it is biased to vacuum and vacuum inflated when it is biased to vacuum.
Place the packing bag equipped with the object in the vacuum room, and place the sealing bag on the heat sealing strip in an orderly manner (for inflatable packaging, at least one nozzle shall be inserted into the sealing bag).
The speed of the press is very high, and the air extraction (vacuum) indicator light on the control panel is on. When the vacuum pump starts to draw air, the engine hood is automatically drawn up. The vacuum screw can adjust the height of the vacuum according to the packaging regulations. When adjusting, the visual scale is from low to top and the force is small.
Seal the goods that must be vacuum packed, then put the opening end on the sealing strip and pay attention to keep the packing bag upright. If it is a small package, it can be packed in several other packages in parallel.
When the pumping time is set (i.e. the specified vacuum degree), the pumping is completed, the pumping indicator light is blown out, and the inflation indicator light is on, so that the inflation of the meter is just started. The inflation button can adjust the inflation time length (i.e. how much is the inflation volume), in the same way as above. If there is no need to inflate, turn the main switch of the power supply to the vacuum position, the program flow will automatically enter the vacuum packaging, and the inflation indicator will blow out.
At the end of air extraction or inflation, the indicator light will blow out and the indicator light of heat seal will be on, i.e. enter into the sealing procedure flow. The control panel will be equipped with a heat seal time and temperature adjustment knob to integrate different thin and thick raw materials. When adjusting the time and temperature, the rotation force should be small to avoid sudden increase of heat seal temperature and burning of heat seal parts.
When the heat sealing time is set, the heat sealing indicator light will blow out to see that the heat sealing is completed, that is, the vacuum chamber will enter the air through the relay until the engine cover is lifted automatically, and the whole process of vacuum inflation packaging is completed, and the next packaging cycle system will be prepared in advance.
