Description

Technical Field

[0001] The utility model belongs to the technical field of bag forming devices, and particularly relates to a bag forming mechanism for an automatic medicine dispensing machine packaging device. Background Art

[0002] At present, when the current packaging paper forms a packaging bag, it mainly uses the hot pressing method. In this way, the sealing efficiency is relatively high. When sealing, it is necessary to ensure that the packaging bag does not move. Since there is a large ductility after heating, if the packaging paper moves during sealing, the packaging paper will be stretched or torn during the sealing process, which will reduce the product qualification rate.

[0003] However, currently, the production of packaging bags usually can only be carried out through a heat sealing device to longitudinally heat seal the two butted edges after the packaging paper is folded, and cannot perform heat sealing along the transverse direction of the packaging paper, which is not conducive to the continuous production efficiency of packaging bags.
