First of all, you need to check if the seal is not sealed. If the seal is not good, then it may be the reason for the heating strip and the airbag. Replace the heating strip and the airbag, and then try to seal the product.
Secondly, check the configuration of the vacuum pump for the automatic packaging bag vacuum packaging machine. For the automatic bag vacuum packaging machine, it is necessary to equip two sets of 100 imported German vacuum pumps for one rough vacuum and two fine vacuum vacuum. After vacuum pumping twice, the vacuum of the product will not be bad;
Whether the third vacuum pump is reversed, this will also be one of the reasons that affect the vacuum degree of the product. It is well known that the fully automatic bag vacuum packaging machine belongs to large vacuum packaging equipment, and needs to use three-phase power, so when the equipment is just started to use, If the electrical phase of the vacuum pump line and the power line are inconsistent, the noise will be large, and the vacuum pump will reverse. If the vacuum pump reverses, it will not work properly and will not be vacuumed.
Fourth, whether the vacuum pump oil is in the 2/3 or 3/4 position of the oil window. If the vacuum pump oil is lower than this oil level, the power of the vacuum pump is lowered, the start of the vacuum pump or the slow start is also the cause of the poor vacuum of the product.
