What Is The Use Of Transformer In Vacuum Skin Packaging Machine?

Semi Automatic Tray Sealing Machine is divided into two types: external pumping and internal pumping, which are used for vacuum packaging of different products. The internal vacuum packaging machine is mainly used to package food, so it is also called food vacuum packaging machine. The external vacuum packaging machine is mainly used to package large goods and products with special shapes. If we distinguish from the shape of the product, we can package granular powder products without pumping, while the external pumping is to package solid and metal parts that are not easy to pump.

The principle of the food vacuum packaging machine is to vacuum first and then seal. The sealed thermal bonding is achieved by short-circuit instantaneous heating. However, we all know that except for a few small vacuum packaging machines, all vacuum packaging machines use 380V industrial power supply, so how to convert it to heat sealing. Use a transformer to convert industrial electricity into 40V power supply to supply the heating system, and use a heating strip to bond and seal the bag by short-circuit heating.

Since the transformer will be damaged after long-term short-circuit operation, the damage is irreversible. With the growth of our export business, the food vacuum packaging machine is also welcomed by many foreign customers. In order to be suitable for external voltage, a transformer can also be used to change the voltage. When we encounter some minor faults in the food vacuum packaging machine, if we cannot handle it ourselves, we can contact after-sales service in time and we will handle it for you as soon as possible.
