If the vacuum packaging machine is not properly operated, there may be some failures. For example, the heating belt of the vacuum packaging machine is broken, and the upper cover of the vacuum packaging machine is not sucked. It may also appear. If the vacuum packaging machine is divided from the form of vacuuming, it can be divided into internal pumping. And pumping outside. The external vacuum packaging machine has no vacuum chamber, but only one suction nozzle is vacuumed by extending into the bag, and the inner vacuum packaging machine has a vacuum chamber, and the articles can be placed in the vacuum chamber. After closing the upper cover of the vacuum chamber, a closed space is formed to perform vacuuming. However, during the working process, sometimes the vacuum cover cannot be closed. The usual solution is as follows:
1. The wires are reversed. If the vacuum connection of the 380v power supply is reversed, the vacuum pump will reverse, and the upper cover of the vacuum chamber will not be able to be sucked, and finally the vacuum can not be generated. In this case, the user only needs to reconnect the wires of the vacuum machine.
2. The travel switch is damaged. When the upper cover of the vacuum chamber is closed, it needs to touch the travel switch on the machine. However, if the upper cover is not touched or the travel switch is faulty or damaged, the upper cover of the vacuum chamber may not be sucked. .
3. The vacuum chamber is deformed. The quality of vacuum packaging machines on the market is uneven. Many vacuum machines are still available when they are just purchased. If they are used for a period of time, they will not be able to properly absorb.
