Description

Technical Field

[0001] The utility model relates to a sealing mechanism for a packaging machine with reciprocating following, belonging to the technical field of packaging machines. Background Art

[0002] During the packaging process of a vertical packaging machine, a packaging film is fed through a film feeding device. The packaging film forms a tube shape through a forming bag mold, the side is heat-sealed through a back-sealing component, and at the same time, the packaging material is injected into the bag, and then the port of the packaging bag is sealed through a sealing mechanism. Since when the sealing mechanism performs hot-press sealing, it is necessary to clamp and heat-seal the bag mouth of the packaging bag through the hot seal heads at both ends for a period of time. At this time, the film feeding device needs to pause the film feeding and wait until the sealing is completed before feeding the film again, resulting in low work efficiency.
