With the improvement of the degree of automation, the operation, maintenance and daily maintenance of the packaging machine are more convenient and simple, and the professional skills requirements of the operators are reduced. The quality of product packaging is directly related to the temperature system, the speed accuracy of the host, and the stability of the tracking system.
Working principle of vacuum packaging machine
After the product is contained in the packaging container, the air in the container is evacuated to reach a predetermined degree of vacuum, and the machine that completes the sealing process is called a vacuum packaging machine.
The vacuum packaging machine is mainly used for packaging products that are prone to oxidation, mildew or moisture deterioration, in order to prolong the use time of the product or prevent the rust of precision parts or instruments, such as the packaging of mustard, sausage, etc.
The films or composite materials commonly used in vacuum packaging should have certain air tightness, pressure resistance and mechanical adaptability.
There are relatively many varieties of vacuum packaging machines, which are usually divided into: mechanical extrusion type, intubation type, etc.
The principle of vacuum packaging of mechanical extrusion vacuum packaging machine is as follows:
After the packaging bag is filled, the air in the bag is mainly removed by elastic items such as sponges on both sides of the bag, and then sealed and packaged, which is called mechanical extrusion. This method is the simplest, but the vacuum degree is low, and it is used in occasions requiring different vacuum degrees.
The vacuum packaging principle of the intubation vacuum packaging machine is: insert the exhaust pipe from the opening of the bag, open the exhaust valve, the vacuum pump will vacuumize, and the packaging method of sealing after reaching the predetermined degree of vacuum is called intubation vacuum packaging. . If inflated, close the exhaust valve after evacuation, and open the inflation valve to inflate.
