The vacuum packaging machine is a product that we are all familiar with. In order to adapt to more product categories and sizes, there are two types of vacuum packaging machines: internal pumping and external pumping. No matter which type is required to be sealed quickly after the vacuum packaging machine is vacuumed, the principle of their sealing device is the same. Today, the editor of Axiomtek will share the sealing principle with you.
The heating of the vacuum packaging machine is heated by copper blocks on both ends of the heating wire installed on the phenolic board, and then the heating wire is covered with an insulation cloth made of special materials. The plane of the vacuum chamber of the vacuum packaging machine will have a rubber strip pressed by the seal. Ours is made of imported silica gel. After the bag is placed in the vacuum chamber, the pressure strip is put down to fix the bag mouth, the upper cover of the vacuum chamber is closed, and the machine starts to work. The first is to vacuum in a closed vacuum chamber, and then the bag is exhausted. Of course, this process is very fast and only takes 10 seconds. When the vacuum is completed, the sealing device will be short-circuited, and there will be a large current to generate heat. The copper blocks at both ends of the heating rod are introduced into the heating wire to instantly heat up, and the vacuum bag is thermally bonded.Therefore, we can see in the control system of the vacuum packaging machine that there is a parameter of cooling time, which is to cool the heated heating wire. If the heating wire continues to heat, the insulation cloth will be smeared or even burned, or it may be burned. Heating wire. In order to achieve a better sealing effect and prolong the life of these wearing parts, our Axiomtek uses imported materials. The heating wire is also specially customized and thicker than other manufacturers on the market. Generally, the conventional one is 8mm. Width, thickness of 0.1mm. Ours is a custom-made 0.3mm thick nickel complex alloy heating wire that is more durable and seals more smoothly. This is also the reason why our price is slightly higher, and we have done well in many details.
