This invention discloses a bag-making device with a roll-up function. A secondary flip motor pre-flips the labeling frame downwards, allowing an antistatic arc plate to cover the rolled plastic bags. A metering pump sprays antistatic liquid through a nozzle frame onto the inner surface of the free end of the plastic bag's tail, facilitating anti-curling and rewinding of the wetted tail end. The antistatic liquid further reduces the amount of frictional static electricity on the inner surface of the free end of the plastic bag's tail. The antistatic brush bristles of the antistatic arc plate flatten the free end of the rolled plastic bag's tail while simultaneously transferring static electricity generated on its outer surface to the antistatic brush body via conductive wires. A hot air blower sprays heated air through an air jet box onto the outer surface of the rolled plastic bag, ironing out any curling at the interface and drying any excess antistatic liquid leaking from the outer surface. This allows the bag-making machine to eliminate static electricity at the free end of each roll of plastic bag.
