The folding problem of stretch film packing machine
The sealing problem of the dry vacuum packing machine is one of the common faults in the use of the food vacuum packing machine. In addition to the sealing is not sealed, the folding of the sealing is also a problem that customers often encounter when using the vacuum packing machine. What is the reason for the folding of the sealing of the vacuum packing machine? The reasons are as follows:
1. Heat insulation cloth aging: this is a common phenomenon among these several kinds. The vacuum packing machine is old. Heat insulation cloth has aging will appear lax sealing, there are wrinkles and other conditions. At this time only need to replace the insulation cloth.
2. Uneven air bag inflation: the principle of sealing is to inflate the air bag and press down, so that the heating belt is glued to the vacuum bag, and the bag is glued together. If the air bag inflates unevenly, there will be pleats at the seal of a certain section. The main reason for this phenomenon is that the air bag has a break, so that the air bag is uneven or leakage.
3. Pressure valve put back: if the vacuum packing machine seal is wrinkled after replacing the pressure valve, and the whole sealing line is wrinkled, it may be the pressure valve put back, the pressure valve has two interfaces, one is connected with the air bag, one is according to the outer end. If the two kinds of connection is opposite, the air bag is not inflated, so that the vacuum packing machine seal has a fold.
