Troubleshooting of sealing machine
Fault 1: The machine is not powered on, because the switch is damaged and the power cord needs to be checked.
Fault 2: The seal is not clear, because the heating blocks are not parallel and the heating wires are uneven. It is necessary to adjust the parallelism of the heating blocks and the flatness of the heating wires.
Fault 3: The two ends of the lacquered cloth are black, and the heating wire is easy to break. The reason is that the sealing time is too long, and the circuit board is damaged. It is necessary to reduce the sealing time and replace the circuit board.
Fault: the plastic bag is stuck at the seal, because the temperature is too high and the lacquer cloth is damaged. It is necessary to adjust the temperature and replace the lacquer cloth.
Fault: The machine is not working, because the microswitch is abnormal and the circuit board is damaged. It is necessary to check the position of the swing arm of the microswitch and replace the circuit board.
Fault: The sealing time is out of control, and the circuit board is damaged, so the circuit board needs to be replaced.
