The invention provides a bag making machine which comprises a heat sealing device 1. When the heat sealing device 1 works, the heat sealing cutter head 20 performs heat sealing work at a near point and stays at the near point for a period of time and then goes to a far point, so that the heat sealing time of a semi-finished product packaging bag formed by plastic films is prolonged, and the effect of the heat sealing device is remarkably improved compared with that of the conventional equipment in the same industry. Therefore, the heat sealing device 1 provided by the invention solves the technical problems that the heat sealing device 1 of the existing bag making machine only depends on short buffer time to carry out heat sealing on the plastic packaging bag, and the heat sealing time is too short, so that the heat sealing is not completed, and the production and use requirements cannot be met.
