The invention discloses a multi-station full-automatic processing all-in-one machine for woven bags. The multi-station full-automatic processing all-in-one machine for woven bags comprises an outer bag cutting machine, inner film manufacturing machines and inner film pulling machines. The at least two inner film manufacturing machines are arranged on the same side of the outer bag cutting machine, a bag moving mechanism is transversely connected between the output end of each inner film manufacturing machine and the outer bag cutting machine, and the output end of each inner film manufacturing machine is connected with the corresponding inner film pulling machine; each inner film manufacturing machine sequentially comprises a driving roller, an inner film scalding knife device, an adjustment device, a fixed-length conveying device and a bridge-crossing conveying device from the input direction to the output direction. Each inner film scalding knife device comprises an upper rolling rod adjustment mechanism, a lower rolling rod adjustment mechanism, an upper scalding knife component and a lower scalding knife component, the upper scalding knife component is arranged in the middle of the upper rolling rod adjustment mechanism, and the lower scalding knife component is arranged in the middle of the lower rolling rod adjustment mechanism. The multi-station full-automatic processing all-in-one machine for woven bags is beneficial to mechanical structure design, achieves simple and convenient manufacturing and smooth movement, is beneficial to electric independent control, can be started and operate simultaneously on the left and right, can also operate independently on a single side, reduces labor and cost and improves processing efficiency.
