The working principle of the aluminum foil sealing machine is as follows:

The aluminum foil sealing machine is mainly composed of 4 parts: main box, lifting frame, conveyor and electromagnetic induction head.
The high-frequency current generated by the mainboard oscillation source in the host is fed back, amplified, and reshaped to push the power amplifier module to output to the induction coil of the electromagnetic induction head.
When there is an aluminum foil (metal) close to the induction coil of the electromagnetic induction head (that is, the plane of the aluminum foil is parallel to the plane of the induction coil), the aluminum foil will induce high-frequency eddy currents and generate heat. The degree of heat generation is determined by the intensity of the eddy current and the frequency. , The length of the induction time is determined. The aluminum foil heats up and generates high temperature instantaneously. When the aluminum foil film and the plastic bottle are of the same material, the aluminum foil film and the plastic bottle mouth in contact with it also melt instantaneously to fuse the aluminum foil and the plastic bottle mouth, thereby making the aluminum foil and the plastic bottle Achieve high-efficiency, high-quality and tight sealing effect.
