In the production line, a feeding mechanism, a puncture hole breaking mechanism, a bottom pulling mechanism 3, a conveying mechanism, a bottom pasting mechanism 9, a bag pressing mechanism and a bag collecting mechanism are all the prior art of a bag making machine; the drum forming mechanism is a structural improvement based on the prior art, one outer ring of a clamping roller of the film-coated roll paper is provided with a circle of protrusions, the outer ring of the other roller of the clamping roller is provided with a circle of grooves matched with the protrusions, the protrusions extend into the grooves, when the film-coated roll paper which is not rolled into a paper drum shape passes through the clamping roller, small edges (like the turned small edges in the figure 3) are pressed out under the matching of the protrusions and the grooves, and then the film-coated roll paper is pressed into a drum; each mechanism behind the bag separating mechanism 4 is respectively arranged along two sides of the bag separating mechanism 4, and each mechanism is symmetrically arranged.
As shown in fig. 3, the edge ironing mechanism 2 includes: the device comprises an air cylinder 21, a first ironing row 22 and a temperature controller 23, wherein the air cylinder 21 drives the first ironing row 22 to vertically move up and down through a connecting piece, and the temperature controller 23 is fixed on the side edge of the first ironing row 22;
in this embodiment, the laminated web is first formed into a web shape through two processes of a feeding mechanism and a drum forming mechanism, then flows to this process, and is ironed to form a first 22 heating the overlapping edge of the laminated web, so that the film of the laminated web in the overlapping edge is melted (the inner films on the two overlapping edges where the web is not adhered after the small edge is pressed out correspond to each other, and the adhesive effect after the edge is ironed is better), the laminated webs on the overlapping edge are adhered together to form the web shape shown by drum forming and edge ironing in fig. 3, and then the pulling roll is pressed and adhered again through the puncturing and breaking process;
the temperature controller 23 of the present embodiment controls the temperature of the ironing line 22 according to the thickness and the material difference of different papers and the moving speed of the papers so as to achieve the best bonding effect; the first ironing row 22 continuously presses the overlapping edge of the paper, and the paper which is subjected to ironing adhesion is pulled by the paper pulling roller to enter the puncturing stretch breaking mechanism.
Preferably, as an alternative embodiment, the distance between the temperature controller 23 and the ironing bank 22 is preferably within 0.5-2 meters. In this embodiment, the temperature controller 23 is not too far away from the first ironing device 22, so that operators can observe the adhesion effect of paper, and is not too close, and operators can be scalded easily.

in this embodiment, the paper bag completed by blowing air to open the bottom is conveyed to the process, the front bag bottom pulling claw 62 firstly pushes and pulls the upper vertex angle of the hexagonal corner of the paper bag, then the rear bag bottom pulling claw 61 pushes and pulls the lower vertex angle of the hexagonal corner, after the two pulling claws pull the paper bag tightly, the paper bag is conveyed into the forming plate 64 at the bottom of the pulling claw sliding rail 63, the forming plate 64 shapes and folds the bottom of the paper bag, the shape blown by the previous bottom opening process is pressed to be more fit, and meanwhile, the bottom of the bag is folded to form a folded part (the folded part is the shape pressed out by the bottom opening of the paper bag in the folded bottom state of fig. 3, but the folded part pressed out by the bottom is not folded at this time, so that the state in the open bottom pressing and hot stamping is still observed in the figure).
As shown in fig. 8, the bag bottom hot stamping and forming mechanism 7 includes: a second ironing bar 71 perpendicular to the moving direction of the paper bag, and a welding wheel 72 arranged behind the second ironing bar 71;
