Introduction of electromagnetic induction aluminum foil sealing
Electromagnetic induction aluminum foil sealing machine is widely used in the sealing of containers of medicines, liquid medicines, spices, detergents, milk, beverages, food, chemical products, etc., and plays the role of sealing, anti-counterfeiting and anti-theft. The equipment uses the principle of electromagnetic induction to instantly generate high temperature on the aluminum foil on the bottle mouth, and then fuse the aluminum foil on the bottle mouth to achieve the function of sealing. It has good moisture-proof, mildew-proof and anti-counterfeiting effects, thereby prolonging the storage time of items.
1, Definition of electromagnetic induction sealing.
Electromagnetic induction sealing, that is, using an aluminum foil sealing machine to heat the aluminum foil sealing pad, so that the heat sealing layer of the aluminum foil sealing pad is heated and melted, and the heat sealing is made under a certain pressure. The layer is bonded to the bottle mouth, so as to achieve the function of sealing the bottle mouth.
The working principle of the electromagnetic induction sealing machine used in the packaging process is the same as the working principle of the induction cooker that people use every day.
It applies the “eddy current effect” of physics, that is, alternating The magnetic field generates an electric field, and the conductor in the electric field generates an electric current.
When the electric current passes through the foreign body, the electric energy is converted into heat.
This sealing process is suitable for most items that need to be protected from contamination.
For example, chemicals such as medicines, food, beverages, pesticides, and petroleum oils can not only effectively protect the products, but also avoid the accident of being overturned, spilled, squeezed and spilled, or maliciously put into other items and damaged.
In addition, electromagnetic induction has the advantages of reducing costs and management costs for sealing machines.
