Common faults and treatment methods of vacuum packaging machines

1. Do not pump vacuum. If the vacuum packaging machine that is used for the first time is not vacuumed, the possibility of the vacuum packaging is that the electric pump is reversed, and the vacuum pump is reversed to make it impossible to evacuate. If it is suddenly not used after a period of use, then there may be a vacuum pump failure or a circuit board failure, and there may be a case where the vacuum chamber is deformed, and the vacuum cover cannot be completely sucked to cause vacuuming. appear.

2, do not seal. If the vacuum packaging machine does not seal, first observe whether the bag has hot marks. If there is, it means that the heating temperature is not enough, just adjust the heating temperature. If the bag does not have a hot mark, then the heating bar has no temperature at all, which may be caused by two conditions, one is that the heating bar is broken or burned, and the other is that the heating transformer is burnt. Users only need to step by step to solve them one by one.

3. The seal is not smooth. The bag appears unevenly in the seal. The seal is wrinkled and there is no obvious pattern at the seal. The wrinkles at the seal are mainly caused by the bag being too short. Generally, the length of the vacuum bag should be 3-4 cm longer than the package, so as to ensure that there is no air leakage during the packaging process. There is no obvious pattern at the seal. This is mostly caused by the heating time being too long. The heating time is too long. The heating belt completely burns the vacuum packaging bag and loses the beauty of the sealing. Therefore, the sealing is not flat.

4. The vacuum is getting lower and lower. In theory, the degree of vacuum can only be known by professional instrument measurement, but some of the more obvious low vacuum can still be seen by the naked eye. For example, it takes 10s to draw a bag of items, but with the use of the machine, vacuuming Time needs to be longer and longer to achieve the initial effect of Zui, which is the performance of the vacuum is getting lower and lower. This happens, mostly because the vacuum pump enters a lot of water, causing the oil in the vacuum pump to be diluted and losing its original function. The vacuum pump enters moisture because the packaged item contains a lot of water, or the package is directly liquid. If such a situation occurs, the user should promptly replace the vacuum pump oil to solve it.

In fact, all the common faults that occur during the use of the equipment can be solved quickly by the operator. There is no need to wait for the professional after-sales service of the supplier to come to the door. This is not only a waste of time, but also a high cost. The operator only needs to carry out simple learning according to the instruction manual, and many problems will be solved.
