the fourth step: starting a rotary driving mechanism to drive a clamping jaw combination mechanism to rotate by 90 degrees to enable the bottom end of a packaging bag to face a bag opening platform, starting the driving mechanism to drive a bag smoothing manipulator to move to the direction of the bag opening platform to the upper side of the bag opening platform on a guide rail, and sliding a sliding bag clamping mechanism to slide down to an initial position along the same direction to loosen a clamping jaw for clamping a handle at the upper end of the packaging bag when the clamping jaw combination mechanism rotates by 90 degrees and starts to move to the direction of the bag opening platform;
the fifth step: starting a bag opening mechanism, extending out a bag opening arm, opening a bottom end opening of the packaging bag through a bag opening sucker, and entering the next procedure;
and a sixth step: and loosening the bag smoothing clamping jaw and the clamping jaw, rotating the driving mechanism to drive the clamping jaw combination mechanism to rotate reversely by 90 degrees, and starting the driving mechanism to drive the bag smoothing manipulator to return to the initial position.
9. The method according to claim 8, wherein when the bag smoothing manipulator is placed at the initial positions of the two sides of the bag extracting mechanism, the bag smoothing clamping jaws are arranged on the upper side and the clamping jaws are arranged on the lower side, and the front ends of the bag smoothing clamping jaws extend out of the front ends of the clamping jaws by at least 50 mm.
10. The method as claimed in claim 8, wherein the bag-stroking gripper has two claw-arm closed contact sides respectively provided with a silica gel claw pad, the surface of the silica gel claw pad is provided with a toothed groove along the bag-stroking direction, the toothed grooves of the two claw-arm silica gel claw pads are arranged in a relative staggered manner, the toothed grooves arranged in a relative manner when the two claw-arm silica gel claw pads clamp the bag edge are mutually meshed to press and clamp the bag edge, the silica gel claw pad is a silica gel claw pad containing a lubricant, the tooth top width of the toothed groove is not more than half of the tooth bottom width of the toothed groove, and the groove depth is at least 2 mm.
