Automatic sealing machine is not tightly sealed

It is very common for the sealing machine to be insecure. When the sealing is not strong, it should be kept as calm as possible. At this time, you need to be able to master some solutions to the sealing machine failure. Then what if the sealing machine is not tight ?

Sealing machine seals are not one of the common failures that occur in sealing opportunities. First, the packaging bag can not be sealed; second, the bag mouth is sealed under the pressure of the sealing knife, but it is opened with a little force to peel or squeeze the sealing; third, the sealing is half sealed and half separated, so The quality of the seal is still unqualified. This situation occurs when the composite lining is OPP and blown PE. These three situations are caused by the lack of sealing.

Briefly analyze the problems and solutions for the sealing of the sealing machine:

The heat sealing temperature is not enough: just raise the heat sealing temperature to solve the problem.

The heat sealing speed is too fast: the speed of the sealing machine will also affect the sealing effect. If the sealing speed is too fast, the sealing part will be transferred to the cold pressing place for cooling in the future, and the sealing will be weak.

The quality of the heat sealing film is not good: if the sealing film composite lining corona is not uniform and the effect is not good, it happens to be in the sealing place, and it certainly cannot be sealed. This situation is rare, but once it appears, the product is definitely scrapped. Therefore, the choice of sealing machine film is also very important.

The pressure of the cold-pressing rubber wheel is not suitable: there is one upper and lower of the cold-pressing rubber wheel, and the pressure between them should be moderate. When adjusting, the spring should be adjusted to adjust the pressure.
