What is the Working Principle of Induction Sealer?

The induction sealing machine uses the principle of induction heating to heat the aluminum foil cover through a high-frequency electromagnetic field to fuse it with the plastic film or aluminum foil sealing layer at the mouth of the container to achieve a sealing effect.

What are the parts of induction sealer?

1. Frame

2. Speed-reducing and speed-regulating transmission mechanism

3. Sealing and printing mechanism

4. Conveying device

5. Electrical and electronic control system

How does a seal machine work?

1. When the power is turned on, each mechanism starts to work.

2. After the electric heating element is energized, the upper and lower heating blocks are heated rapidly, and the temperature is adjusted to the required temperature through the temperature control system.

3. The impression wheel rotates, and the cooling system starts to cool as needed, and the conveyor belt transfers. And adjusted to the required speed by the speed regulating device.

4. When the package containing the items is placed on the conveyor belt, the sealing part of the bag is automatically sent between the two sealing belts in operation and brought into the heating zone.

5. The heat of the heating block is transferred to the sealing part of the bag through the sealing belt.

6. The film is heated and melted, and then passed through the cooling zone to make the surface temperature of the film drop appropriately.

7. Then rolled by the knurling wheel (or printing wheel), so that the upper and lower plastic films of the sealing part are glued and pressed into a net pattern (or printed logo) ).

8. Then the sealed packaging bag is sent out of the machine by the guiding rubber belt and the conveyor belt to complete the sealing operation.
