c, vertically conveying, wherein the packaging bag 100 subjected to bag opening treatment is pressed and bound at four corners of the bag opening of the packaging bag 100 by a bag hook group 31 at the top of a bag support tool 30, and the packaging bag 100 is conveyed along a preset path in a vertical state with the bag opening facing upwards;

d, blanking, namely conveying the packaging bag 100 to a blanking station 101 through a vertical circulating conveying assembly 3, and quantitatively blanking the packaging bag 100 through a blanking assembly 4 positioned at the blanking station 101;

step e, sealing, namely transferring the discharged packaging bag 100 to a sealing station 102 through a vertical circulating conveying assembly 3, and performing folding and flattening treatment on the bag mouth of the packaging bag 100 by a sealing assembly 5 positioned at the sealing station 102, and then performing sealing treatment on the bag mouth;

and f, weighing and outputting, wherein the packaging bag 100 after being sealed is transferred to a weighing station 103 through the vertical type circulating conveying assembly 3, the packaging bag 100 in the bag support tool 30 is pushed out by the weighing output assembly 6 and then is weighed, and the bag support tool 30 is circularly reset to the position below the bag opening and opening assembly 2.

In step a, after the connected packaging bags 100 in the magazine 12 are completely discharged, the sensor 111 in the bag-out detection mechanism 11 senses that the packaging bags 100 in the magazine 12 are discharged, and the tail end of the packaging bag 100 of the batch is overlapped and bonded with the head end of the packaging bag 100 of the next batch by the bag connecting plate 112, so that the purpose of connecting the packaging bags of the two batches one after the other is achieved.

Further, in the step b, during the bag opening process of the packaging bag 100, after the bag opening process of the packaging bag 100 is completed, the shaping block 214 in the bag opening and bag opening assembly 2 falls into the mouth of the bag, and shapes the mouth of the packaging bag 100, so that the mouth of the packaging bag 100 has a regular shape.

More specifically, in step c, the bag holder assembly 30 conveys the packaging bag 100 along a predetermined path in a vertical state in which the opening of the bag mouth is facing upward, so that the bag mouth of the packaging bag 100 can be smoothly fed and sealed.

In addition, in step e, before the sealing of the packaging bag 100 is performed, the packaging bag 100 needs to be folded and flattened through the flattening transmission mechanism 51, so that the sealing performance of the mouth of the packaging bag 100 is stronger.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
