Packaging machine companies share the reasons why vacuum packaging machines do not suck
If the vacuum packaging machine is divided into the form of vacuuming, it can be divided into internal pumping type and external pumping type. The external vacuum packaging machine does not have a vacuum chamber, only one suction nozzle extends into the bag for vacuuming, while the internal vacuum packaging machine has a vacuum chamber, the items can be placed in the vacuum chamber, and the vacuum is closed. A closed space is formed after the upper cover of the chamber, so it can be evacuated, but in the process of work, it often happens that the upper cover of the vacuum machine cannot be closed. How to solve this? The wire is reversed. The vacuum packaging machine using 380v power supply If the power supply wiring is reversed, the vacuum pump will be reversed, and the upper cover of the vacuum chamber will not be able to be sucked and closed, and finally it will not be possible to vacuumize. 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 is necessary 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 cannot be A pull-in situation occurs. 3. Vacuum chamber deformation The quality of vacuum packaging machines on the market is uneven. Many vacuum machines look okay when they are just purchased, but they will be deformed after using for a period of time. At this time, the upper cover of the vacuum packaging machine cannot be pulled together of. To sum up, there are many reasons why the upper cover of the vacuum packaging machine cannot be closed. Users only need to compare and solve them one by one, and they can solve the fault of the vacuum packaging machine very quickly.
