Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a vacuum sealing machine. Background Art

[0002] The existing aerosol can sealing equipment is mainly used for medical 20mm valve aerosols. Since the outer diameter of the 20mm valve of the medical aerosol can is between 21.5-21.6mm, and the aluminum can body is 22.00mm, the size difference is not big, so it is designed in this way. The sealing pressure of the 20mm valve must reach 40 kg, otherwise the valve sealing ring will not expand completely and cause leakage. Some existing medicines must be evacuated before the aerosol can is sealed to avoid moisture in the air affecting the quality of the medicine. Utility Model Content
