What is Sealing machine?

The sealing machine refers to the machine that seals the container after the packaging container is filled with the product.

What type of packaging material is a heat sealer used to seal?

There are many materials used to make packaging containers, such as paper, plastic, glass, ceramics, metal, composite materials, etc. The shape and physical properties of packaging containers are also different.

What are the parts of sealing machine?

Generally, the sealing machine is composed of a frame, a speed-reducing and speed-regulating transmission mechanism, a sealing and printing mechanism, a conveying device and an electrical and electronic control system.

What is the working principle of the sealing machine?

1. Power On

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

2. Heating

After the electric heating element is energized, it heats up the upper and lower heating blocks sharply, and adjusts to the required temperature through the temperature control system.

3. Rotation and Cooling

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

4. Package Placement

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. Sealing

The heat of the heating block is transferred to the sealing part of the bag through the sealing belt. The film is heated and melted.

6. Cooling and Printing

Then passed through the cooling zone to make the surface temperature of the film drop appropriately, and 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) )

7. Packaging Completion

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.
