Description

Technical Field

[0001] The utility model relates to the technical field of medicine production equipment, in particular to a heat sealing mechanism for a medicine packaging bottle. Background Art

[0002] The heat sealing process of drug packaging bottles is to first place a sealing film on the bottle mouth, and then heat the bottle mouth or the hot melt adhesive adhered to it by various means to melt part of the plastic or hot melt adhesive at the bottle mouth. After the bottle mouth leaves the electric heating area, the melted plastic or hot melt adhesive will cool down, so that the sealing film and the bottle mouth are bonded together to achieve the effect of sealing the bottle mouth.

[0003] When the existing round-mouth bottles pass through the heating area, the gas in the bottle will expand, thereby breaking the sealing film, resulting in incomplete sealing at the air flow escape site. At this time, the bottles need to be recycled and reworked, which seriously affects production efficiency. Utility Model Content
