If the packaging bag is a zipper bag, after the packaging bag is taken down from the storage tank of the bag storage device 20 by the bag taking sucker 302 of the bag taking device 30, the pre-opening sucker 8013 of the zipper opening device 80 extends to the pre-opening position, the bag taking sucker 302 moves upwards for a section and then moves downwards, the pre-opening of the mouth of the zipper bag is realized by matching with the pre-opening sucker 8013, and then the zipper opening device 80 continues to move, namely, the zipper on the mouth of the bag is directly opened after two ends of the mouth of the bag are clamped.

After the zipper opening device 80 is reset, the bag taking sucker 302 continues to rotate by 90 degrees, if the bag clamping position waits, the empty bag is directly supplied to the position, and the bag opening is completely opened by the auxiliary bag opening device 110 arranged at the rear position and the bag clamping device 40. If the bag is flat, the step of opening the zipper is omitted, and the bag-taking sucker 302 is directly rotated by 90 degrees and the empty bag is fed into place.

After the bag mouth of the empty bag is completely opened, the discharging hopper 501 of the discharging device 50 firstly goes downwards, and the lower end of the discharging hopper 501 is inserted into the bag.

After the discharging hopper 501 descends to the position, the sub-packaging weighing device 90 performs discharging action, the materials enter the bag through the discharging hopper 501, and if the drying agents need to be added, the drying agent supplying device 120 supplies the drying agents at the same time. Then the lower material beating device 130 carries out bag beating action to make the materials enter the bag bottom as far as possible.

For materials which are difficult to fall into the bag freely, the poking and pushing head 505 moves downwards to push the materials into the bag.

The poking material pushing head 505 and the blanking hopper 501 respectively move upwards and retreat to the right, the clamping jaw structure on the bag clamping device 40 moves leftwards or rightwards to realize station conversion, namely, the filled material is moved to the sealing device 70, and the empty jaw is moved to the middle position to take the bag for filling.

After the packaging bag is moved to the sealing position, a suction pipe 601 of the vacuumizing device 60 on the packaging bag is inserted into the packaging bag downwards, then a clamping jaw on the bag clamping device 40 is pulled outwards, the bag opening is firstly pulled flat, then a vacuum sealing strip on the sealing device 70 is pressed, external vacuumizing is started, and if nitrogen charging is needed, vacuumizing is completed and then nitrogen charging is converted; and after the vacuumizing is finished, the sealing strip is continuously pressed, so that the sealing action is realized.

After the above-mentioned actions are completed, the clamping jaws on the bag clamping device 40 are loosened, and the finished product packaging bags are fed out after sliding into the finished product output device 100 in the middle through the chutes on both sides.

The whole structure of the machine is integrated and combined, the integrated type is to integrate the subpackaging and weighing device 90 into the whole machine, the combined type is to separate the subpackaging and weighing device 90 from the packaging machine, the packaging machine is universal, and the machine can be used for different subpackaging and weighing requirements, such as filling and the like.

And the bag clamping device of the machine is of a horizontal double-station type, so that the packaging speed is improved.
