The external vacuum packaging machine can be vacuumed, sealed or inflated. How does the external vacuum packaging machine achieve sealing? The external vacuum type vacuum packaging machine draws a vacuum through the suction nozzle into the bag, and on the vacuum packaging machine panel, when the sealing mode is selected, the suction nozzle is recovered and the sealing time is adjusted. Sealing can be achieved by pressing the foot switch. This is the working process of sealing the outer vacuum packaging machine.
From the working principle, when it is adjusted to the sealing mode, the foot switch is pressed, the cylinder control sealing line is pressed down, the externally pumping vacuum packaging machine transformer starts working, and the sealing strip is heated, and the bag is heated by the sealing strip, and the heat is melted. Together, it is worth noting that although only the sealed vacuum packaging machine needs to be connected to the air source.
The external vacuum packaging machine has two modes of operation, manual and automatic. Adjusting the sealing mode of the external vacuum packaging machine allows the vacuum packaging equipment to achieve a good sealing function. After setting the working procedure, the vacuum packaging machine enters the standby state, the suction nozzle and the inflation nozzle are extended, the packaging bag is approached to the air nozzle, the distance between the packaging bag mouth and the sealing line is adjusted, and the sensing switch is reacted, and the external drawing type is adopted. The vacuum packaging machine started working.
1. Pull down the cylinder of the vacuum packaging machine and press the bag opening.
2. In order to achieve a good vacuuming effect, the bag should be as close as possible to the suction nozzle.
3. After setting the pumping time, the vacuum packaging machine runs according to the set program.
4. After vacuuming, go to the next process. If it needs to be inflated, vacuum packaging will enter the inflation mode.
5. After filling the gas, the external vacuum packaging machine is heat sealed.
6. After the heat sealing work is completed, there will be a cooling time until the cooling time is over, and the external vacuum packaging machine returns to the standby state, and one packaging cycle is completed.
