transferring the square bottom bag to a suction bag separating space position, respectively sucking two sides of the bottom bag by a first suction piece (41) and a second suction piece (51), withdrawing, and opening the square bottom bag;
thirdly, after the third suction piece (53) and the fourth suction piece (54) adsorb two sides of the square-bottom bag, the first suction piece (41) and the second suction piece (51) release the square-bottom bag, the vertical moving mechanism (9) moves downwards, the square-bottom bag is sleeved on the bag supporting bracket (52) positioned at the first position, and then the third suction piece (53) and the fourth suction piece (54) release the square-bottom bag;
step four, the bag supporting bracket (52) moves to a second position, and the pressing mechanism (6) acts to press and seal the back cover of the square bottom bag, so that the automatic bottom pressing of the square bottom bag is realized;
and fifthly, after the pressing mechanism (6) is removed, the bag supporting bracket (52) carries the square-bottom bags with the pressed bottoms to continue to move to the third position, and the second bag taking mechanism (7) takes down and removes the square-bottom bags with the pressed bottoms to complete automatic feeding, bottom pressing and discharging cycles of the square-bottom bags.
