Abstract

The invention discloses a plastic bag strapping machine. The plastic bag strapping machine comprises a machine frame, a vibration disc device and a plastic bag conveying device. The plastic bag strapping machine is characterized in that a U-shaped notch is arranged on the vibration disc device; a rubber band expansion device is arranged at the position corresponding to the U-shaped notch; the rubber band expansion device comprises a bracket; the bracket is provided with an upper side supporting rod, a bottom side supporting rod, two side supporting rods and an expansion cylinder; an insertionmoving mechanism is connected between the bracket and the machine frame; and the plurality of supporting rods penetrate through the U-shaped notch to be inserted into an inner hole of a rubber band under driving of the insertion moving mechanism, so that the rubber band is expanded in one direction and taken out from the U-shaped notch after being narrowed, and then stretched again. Compared withthe prior art, the plastic bag strapping machine omits a rubber band transfer mechanism and a driving device thereof, so that the whole machine is compact in structure, the working procedure is simplified, and the grasping and expansion work of the rubber band is reliable and stable.
