The patent uses a press to press the inflatable bag onto the mold for heat sealing. The wavy protrusions on the inflatable bag form an air column that heat-seals the upper and lower layers of the film together to form the gourd bubble inflatable bag. The straight protrusions heat-seal the edges on both sides of the inflatable bag. The bag can be formed in one process, which is convenient, fast and time-saving.

When the electric heating knife 17 fixed on the upper mold 20 contacts the lower mold 21, the electric heating knife 17 performs heat sealing operation on the position of the packaging bag that needs to be heat sealed. At this time, the spring damper 18 is driven to move downward during the downward movement of the upper mold 20. At the same time, the spring damper 18 contacts the contact switch 24 during the downward movement, so that the contact switch 24 controls the start of the condenser 22 to condense the cooling water inside the condensation tube 23. The cold air generated during the condensation process is conducted to the heat sealing position through the lower mold 21, thereby increasing the cooling speed after the heat sealing is completed.
