Description

Technical Field

[0002] An aluminum foil sealing machine uses the principle of electromagnetic induction. A high-frequency generator generates high-frequency current, which passes through an induction coil to generate a strong high-frequency electromagnetic field, instantaneously generating high heat on the aluminum foil sheet on the bottle mouth, and then fusing it on the bottle mouth to achieve the sealing function. During the production and processing of laundry detergent, it is necessary to use an aluminum foil to seal the laundry detergent bottles after filling them with laundry detergent. However, for most aluminum foil sealing machines on the existing market, the up and down positions of the electromagnetic induction heater are adjusted by a handwheel. The electromagnetic induction heater cannot be automatically adjusted up and down, and the thermal efficiency is not high. When manually adjusting the aluminum foil sealing of products at different heights, the adjusted height is not accurate, resulting in waste of energy and poor user experience. Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to improve the prior art. Content of the Utility Model
