Description

Technical Field

[0001] The utility model relates to the technical field of contact lens manufacturing, in particular to a heating and sealing device of a contact lens packaging machine. Background Art

[0002] Contact lenses, also known as corneal contact lenses, are used to correct vision and enhance beauty. In order to protect the lenses, they need to be packaged. The traditional packaging method is to place the contact lenses in a PP cup filled with a special preservation liquid, and then adhere the aluminum foil firmly to the mouth of the PP cup through a heating and sealing process to form a tightly sealed environment to prevent liquid leakage and protect the lenses from contamination or damage. Existing packaging methods make it difficult to accurately control the pressure during the sealing process. Excessive pressure may cause the PP cup structure to be damaged and deformed, while insufficient pressure will cause the risk of poor sealing and liquid leakage, resulting in leakage at the PP cup seal.
