The second cutter 35 is arranged on a cutter seat 34. The cutter seat 34 is connected to a fourth mobile driving assembly. Specifically, the fourth mobile driving assembly includes a second motor 31. The output end of the second motor 31 is connected to a rotating disk 32. One end of a transmission arm 33 is eccentrically hinged to the rotating disk 32. The other end of the transmission arm 33 is hinged to the cutter seat 34. The cutter seat 34 is slidably arranged on the mounting seat 12.

In addition, a slitting component 3 is also arranged between the packaging substrate unwinding rack 1 and the feed tube 6, which can cut the substrate into multiple strips first to meet the structure of the subsequent arrangement of multiple feed tubes 6 and realize multiple groups of synchronous packaging operations. The slitting component 3 is a cooperatively arranged upper vertical cutter and a lower vertical cutter. A shaping roller 37 is provided corresponding to the feeding tube 6, and the shaping roller 37 has a shaping groove 38 that cooperates with the feeding tube 6.

[0017] The working principle of the present invention is as follows: the packaging substrate 2 is unrolled and cut into multiple strips by the slitting assembly 3, and is formed into a cylindrical shape by the feeding tube 6 and the shaping roller 37 and the bag forming guide. Then, by controlling the action of the vertical sealing assembly, the position where the two ends of the cylindrical bag substrate are pressed together is vertically sealed. At this time, the lifting seat 9 is in a high position, and the horizontal sealing assembly on the lifting seat 9 is actuated to clamp the packaging bag substrate for horizontal heat sealing at the bottom position. At the same time, the lifting seat 9 descends, pulling the packaging substrate downward to complete the heat sealing. After it is lowered into place, the transverse sealing assembly releases the packaging substrate, the lifting seat 9 rises and resets, the hopper assembly 4 opens and feeds the filled material into the packaging substrate that has been sealed on three sides through the feeding pipe 6, and then the transverse sealing assembly on the lifting seat 9 clamps and heat-seals the opening at the top of the package, and at the same time, the lifting seat 9 descends again to pull the packaging bag downward, and this cycle is repeated to achieve the heat sealing and feeding operations of the packaging bag. When the packaging bag that has been heat-sealed and fed drops to the cutting assembly, the cutting assembly cuts the packaging bag into a single bag or multiple bags that fall and are fed out.

[0018] This structure of the present invention, by arranging a plastic roller and a bag forming guide to cooperate with the discharge pipe, can realize the forming of a single roll of substrate into a cylindrical bag, effectively reducing the number of unrolled substrates, making its forming more convenient and ensuring the forming quality; by arranging the hopper assembly, the discharge pipe, the vertical sealing assembly, the lifting seat and the cutting assembly in sequence from top to bottom, the packaging substrate can complete the loading, heat sealing and cutting operations in the process of moving vertically downward, which can greatly reduce the occupied area required by the equipment and facilitate its layout in the workshop; in addition, by arranging the transverse sealing assembly on the lifting seat, the transverse sealing assembly can pull the packaging substrate downward for transportation when transversely sealing the packaging substrate, so the equipment does not need to be additionally configured with a traction assembly, making its structure simpler.
