And a third step of: the sliding bag clamping mechanism slides upwards to lift the packaging bag to a set position, the set position enables clamping jaws opened by the bag straightening mechanical arm to be just placed on two sides of the lower end of the packaging bag, the standing bag straightening clamping jaws smooth the folded packaging bag along with lifting of the packaging bag, and then the clamping jaws are closed to clamp the two sides of the bottom end of the packaging bag;
Fourth step: starting a rotary driving mechanism to drive a clamping jaw combination mechanism to rotate by 90 degrees so as to enable the bottom end of a packaging bag to face a bag opening platform, starting the driving mechanism to drive a bag straightening manipulator to move above the bag opening platform in the direction of the bag opening platform on a guide rail, and sliding a clamping jaw mechanism to slide down to an initial position in order to loosen a clamping jaw for clamping a lifting handle at the upper end of the packaging bag while the clamping jaw combination mechanism rotates by 90 degrees and starts to move in the direction of the bag opening platform;
Fifth step: starting a bag opening mechanism, extending out of a bag opening arm to open the bottom port of the packaging bag through a bag opening sucker, and entering the next process;
sixth step: loosening the bag straightening clamping jaw and the clamping jaw, driving the clamping jaw combination mechanism to reversely rotate by 90 degrees by the rotation driving mechanism, and starting the driving mechanism to drive the bag straightening mechanical arm to return to the initial position.
7. The method according to claim 6, wherein when the bag stroking manipulator is placed at the initial positions on both sides of the bag extracting mechanism, the bag stroking clamping jaws are arranged at the upper part and the lower part, and the front ends of the bag stroking clamping jaws extend out of the front ends of the clamping jaws by at least 50mm.
8. The method according to claim 6, wherein a silica gel jaw pad is respectively arranged on the closing contact side of two jaw arms of the bag-stroking jaw, tooth-shaped grooves along the running direction of the bag stroking are formed in the surface of the silica gel jaw pad, the tooth-shaped grooves of the two jaw arm silica gel jaw pads are oppositely staggered, the two jaw arm silica gel jaw pads clamp the bag edge, the oppositely arranged tooth-shaped grooves are mutually meshed and pressed to clamp the bag edge, the silica gel jaw pad is a silica gel jaw pad containing lubricant, the tooth top width of the tooth-shaped grooves is not more than half of the tooth bottom width of the tooth-shaped grooves, and the groove depth is at least 2mm.
