Vacuum packing machine common problems and solutions

The vacuum packaging machine may have many problems in packaging the articles, and these problems may appear from time to time, and any manufacturer's equipment will appear. These are common problems of vacuum packaging machines, also known as vacuum packaging machines. Common failures, although these common failures are not major problems, but it will affect the normal production, so not timely and effective solution is to cause major problems, the common failures of vacuum packaging machines are mainly manifested in the following aspects:
    1, do not vacuum. If the vacuum packaging machine used for the first time is not evacuated, the greatest possibility is that the electrical connection is reversed, and the reverse rotation of the vacuum pump will cause no vacuum. If it is used for a period of time and suddenly does not vacuum, then it may be due to a vacuum pump failure or a circuit board failure. Another possibility is that the vacuum chamber is deformed, and the vacuum lid cannot fully pull in and cause no vacuum. appear.
    2, do not seal. If the vacuum packaging machine does not seal the first case, you must first observe whether the bag has burned traces, if there is, then it shows that the heating temperature is not enough, just need to adjust the heating temperature. If the bag has not been burned, it means that there is no temperature at all in the heated bar. This may be caused by two conditions. One is that the heated bar is broken or burned, and the other is that the heating transformer is burned. Users only need to step by step check one by one to solve.
   3, sealing is not smooth. The appearance of seals in bags is generally indicated by the fact that there are folds in the seals and no obvious patterns in the seals. The folds at the sealing area are mainly caused by short bags. In general, the length of the vacuum bag should be 3-4 cm longer than the package, so as to fully ensure that no air leakage occurs during the package process. There is no obvious pattern in the sealing area. This is mostly caused by too long heating time. The heating time is too long. The heating belt will completely heat the vacuum packaging bag and lose the beautiful appearance of the sealing. Therefore, the sealing unevenness may also occur.
   4, vacuum is getting lower and lower. Theoretically speaking, the degree of vacuum can only be known through professional instrument measurement, but some of the more obvious low vacuum levels can still be seen by the naked eye. For example, it takes 10 s for a bag to be pumped, but as the machine is used, vacuum is used. It takes more and more time to reach the initial effect, which is the performance of the vacuum is getting lower and lower. In this case, it is mostly because the vacuum pump has entered a large amount of moisture, which causes the oil in the vacuum pump to be diluted and lose its original function. The reason why the vacuum pump enters moisture is because the packaged items contain a lot of moisture, or the package is directly a liquid. If this happens, the user should promptly replace the vacuum pump oil to resolve.
       In fact, all the common faults that occur during the use of the equipment can be quickly resolved by the operator. There is no need to wait for the professional after-sales service of the supplier. This not only wastes time but also costs more. The operator only needs to learn the instruction manual for simple learning. Many problems will be solved.
