As a vacuum packaging machines supplier, I will introduce it to you.
The vacuum packaging machine may have some common problems in the process of vacuum packaging articles. If it is not solved in time, it will affect the normal production and even cause bigger problems.
Vacuum Packing Machine
The reason why the vacuum packaging machine is not vacuumed for the first time may be that the electrical connection is reversed, and the vacuum pump cannot be vacuumed due to the reversal of the vacuum pump. In this case, just pick it back. However, if the vacuum suddenly stops after a period of use, it may be caused by a vacuum pump failure or a circuit board failure. In this case, you need to troubleshoot the cause and perform maintenance. Another possibility is that the vacuum chamber is deformed, and the upper cover of the vacuum machine cannot be completely closed, resulting in a situation where the vacuum cannot be drawn. This is more complicated and requires dedicated maintenance.
First of all, observe whether the bag has any traces of ironing. If there is, it means that the heating temperature is not enough. Just adjust the heating temperature. If the bag has no traces of being burned, it means that the heating strip has no temperature at all, and it must be discussed separately. One is that the heating bar is broken or burned, and the other is that the heating transformer is burned. In this case, check it out step by step and then replace or repair it.
Uneven seals are generally manifested as wrinkles in the seal and no obvious patterns at the seal. The wrinkles at the seal are mainly caused by the bag being too short, just adjust the length of the bag. Generally speaking, the length of the vacuum packaging bag should be 3-4cm longer than the packaging, so as to fully ensure that there will be no air leakage during the packaging process; if there is no obvious pattern at the sealing part, the heating time is mostly too long, and the vacuum packaging bag is completely If it is caused by scalding, shorten the heating time.
Generally, the naked eye cannot see the change of the vacuum degree, but it can be judged by the vacuum time. For example, originally it takes 10s to draw a bag of items, but the vacuuming time will need to be longer and longer to achieve the initial effect, which is the performance of the lower and lower vacuum. Generally, this situation is caused by the vacuum pump entering a large amount of water, which causes the oil in the vacuum pump to be diluted. You can solve this problem by replacing the vacuum pump oil in time.
Pay attention to the maintenance and maintenance of the vacuum packaging machine during daily use to eliminate the fault in the bud.
Schedule regular shutdowns for maintenance in accordance with the vacuum packaging machine equipment wear cycle plan.
Monitor the equipment status of the vacuum packaging machine, find hidden troubles or potential failures, and arrange timely maintenance in time.
Regular maintenance can keep the vacuum packaging machine in good working condition, thereby prolonging the service life of the machine.
