A sealing, cutting and shrinking machine is a device used to package products. It is mainly used to seal and shrink the packaging material so that it is tightly wrapped around the product.

The working principle of the sealing, cutting and shrinking machine is as follows:

Preparation: First, place the product on the workbench of the sealing, cutting and shrinking machine and prepare the packaging material, usually a heat shrink film.

Sealing: Place the product on the sealing area of ​​the sealing, cutting and shrinking machine and start the machine. The sealing, cutting and shrinking machine heats both sides of the packaging material through the heating element and seals it together to form a sealed bag.

Shrinking: After sealing, the sealing, cutting and shrinking machine starts the hot air circulation system to shrink the packaging material by blowing hot air into the bag. This allows the packaging material to fit the surface of the product more closely, providing better protection and display effects.

Cooling: After shrinking is completed, the sealing, cutting and shrinking machine stops heating and cools the bag through the cooling system. This allows the packaging material to solidify and remain in a contracted state.

Dust removal: In addition, the sealing, cutting and shrinking machine may be equipped with a dust removal system to remove dust and impurities on the surface of the packaging material to keep the packaging clean.

In summary, the working principle of the sealing, cutting and shrinking packaging machine includes the steps of sealing, shrinking, cooling and dust removal, through which the product can be packaged and protected.
