The Structure Of Vacuum Skin Packaging Machine

In industrial enterprises, the products that need to be packaged are particularly large and heavy. Therefore, most of the indicators of the packaging bags will also be made of composite films. And the sealing width is required to be wider than that of ordinary food bags. The sealing principle of Automatic Tray Sealing Machine is to heat the heating strip by instantaneous heating current, and then place imported heat insulation cloth on it to separate it, but the packaging bag can be heated and bonded.

If the heating belt is too wide, the entire heating belt will be heated unevenly, resulting in failure to seal normally. The narrower the ideal heating belt, the better the instantaneous heating effect and the better the sealing effect. If you are worried about air leakage, you can choose to seal multiple times. We are now using imported nickel alloy with a width of 8mm and a thickness of 0.5mm. Although the common heating belts on the market are all 8mm wide, the thickness is basically 0.1mm.

When the heating belt is heated instantly, the heating is uneven, so the sealing is generally not ideal. It is a multi-station continuous production equipment for belt conveyors. It is simple to operate, simple to maintain, widely used, low cost, high efficiency, and is also unmatched by other equipment. Because its design is relatively simple, light in size, and easy to transport. Not only that, its performance is relatively stable and its running speed is relatively fast.

Its structure consists of an electrical system, a vacuum system, a heat sealing system and a conveyor belt system. During operation, the packaged items are placed on the conveyor belt after bagging. The pneumatic-electrical control system is used to move the conveyor belt forward to the working position, and then exhaust the oxygen in the bag and seal the vacuum chamber. Therefore, the effect of vacuum packaging is achieved.
