The invention discloses a novel coiled plastic bag packaging machine. The novel coiled plastic bag packaging machine structurally comprises a rack, an upper working chamber, a packaging bag pressing bar, a control panel, a sealing supporting groove, vacuum pumps and a packaging bag supplement prompt device. The upper working chamber is movably connected to the left portion of the upper end surfaceof the rack. The packaging bag pressing bar is mechanically connected to the right portion of the upper end surface of the rack. The sealing supporting groove is fixedly connected to the right portion of the upper end surface of the packaging bag pressing bar. The vacuum pumps are fixedly connected to the lower right portion of an internal cavity of the rack. The packaging bag supplement prompt device is movably connected to the left portion of the internal cavity of the rack. The novel coiled plastic bag packaging machine can achieve continuous packaging in the independent packaging processof plastic bags and can conduct induction on the margins of packaging bags on the packaging bag pressing bar of the machine and give a certain prompt when the margins are insufficient to prevent machine idling due to the fact that packaging bags cannot be implemented in time. The packaging efficiency and quality are guaranteed. The stability of the machine is effectively improved.
