Beschreibung
Zusammenfassung:	The invention provides an automatic plastic bag production line comprising a plastic bag sealing-cutting machine and a plastic bag punching machine. The plastic bag sealing-cutting machine comprises a rear feeding mechanism, sealing mechanisms, a front feeding portion and a film squeezing mechanism. Each sealing mechanism comprises a sealing cutter beam. Sealing cutter pressing plates are parallelly arranged under the sealing cutter beams. Two ends of each sealing cutter pressing plate are both provided with connecting blocks. Sealing cutter guide rods penetrate the connecting blocks. One end of each sealing cutter guide rod penetrates the connecting block to be connected to two ends of the sealing cutter beam, and the other end of each sealing cutter guide rod is connected with a first power mechanism. The sealing cutter pressing plates are provided with sealing cutters and arranged parallelly upon the sealing rollers. The automatic plastic bag production line is high in operating efficiency and processing precision, low in error rate and labor cost and applicable to large-scale promotion and application.
