[0020] The working principle of the utility model is that the roll paper is unwound by the unwinding mechanism 1, conveyed by the first traction mechanism 2 and the second traction mechanism 9, tension adjusted by the tension adjusting mechanism 4 in sequence, sealed flanging, die-cutting of M-shaped inserting edge and indentation of folding part are carried out by the die-cutting and creasing mechanism 5, waste edge produced by die-cutting is removed by the waste edge removing mechanism 6, material storage and buffering are carried out by the material storage mechanism, two folding edges on both sides of the front bag surface and one folding edge on both sides of the rear bag surface are carried out by the folding mechanism 8, the second folding edge of the front bag surface and the folding edge of the rear bag surface are sprayed with glue by the glue spraying mechanism 10, cut by the cutting mechanism 11 to form an independently unfolded bag body, the front bag surface and the rear bag surface are overlapped by the folding mechanism 12, the corresponding folding edges are bonded to form M-shaped inserting edge, and the finished paper bag is conveyed to the bag discharging mechanism 13, and the bag discharging mechanism 13 carries out the delivery of the finished paper bag.

[0021] As a further improved specific implementation, the waste edge removal mechanism 6 includes an upper traction roller, a middle traction roller and a lower traction roller. The upper traction roller and the middle traction roller cooperate with each other to carry out the front traction of the material and the waste edge, and the middle traction roller and the lower traction roller cooperate with each other to carry out the rear traction and removal of the waste edge. During operation, the die-cutting and creasing finished material and waste edge enter between the upper traction roller and the middle traction roller, and the material is then transferred to the next material storage process, while the waste edge rotates and enters between the middle traction roller and the lower traction roller for external discharge and collection. Among them, the waste edge removal mechanism 6 can also be implemented by two groups of traction rollers, which is a similar solution.

[0022] As a further improved specific implementation method, the folding mechanism 8 includes a folding table 81, a positioning frame 82 arranged above the folding table 81, a guide wheel 83 arranged at the entrance end of the folding table 81, a pressure wheel arranged at the exit end of the folding table 81, and folding plates 84 and folding guide rods 85 arranged on both sides of the folding table 81. The folding plates 84 are angle plates, which are arranged along the conveying direction and gradually become lower. The folding guide rods 85 are located on the outside of the folding plates 84, and there is a paper guiding gap between the folding guide rods 85 and the folding table 81.

[0023] When the folding mechanism 8 is working, the material enters between the folding table 81 and the positioning frame 82 under the action of the guide wheel 83, and the side edge of the front bag surface enters between the folding guide rod 85 and the folding table 81 to complete the first folding. The outer edge of the first folding touches the folding plate 84, and the second folding is completed under the continuous action of the folding plate 84. The side edge of the rear bag surface is narrower, and only one folding is completed under the action of the folding guide rod 85.

[0024] As a further improved specific implementation, the hemming guide rod 85 gradually approaches the hemming plate 84 along the conveying direction, further assisting the final folding of the second hem.

The folding plate 125 can be raised and lowered, and preferably the folding plate 125 is set on a lifting seat and driven by a cylinder. When working, the bag body that enters the front material platform 121 and the rear material platform 122 is cut off, and the lowered folding plate 125 acts on the middle part of the bag body, and the bag body is pushed down to between the front traction roller 123 and the rear traction roller 124, and is transported downward under the action of the front traction roller 123 and the rear traction roller 124. During the transportation process, the bag body is squeezed so that the corresponding glued folded edges are bonded to each other to form a finished paper bag.

[0026] As a further improved specific implementation, the front and rear sides of the folding plate 125 are also equipped with guide rollers 126, and the height position of the guide rollers 126 is adjustable, which can be adjusted by a cylinder or a screw. The guide rollers are used to guide the front bag surface and the rear bag surface to enter between the front traction roller and the rear traction roller.

[0027] As a further improved specific implementation, the bag discharging mechanism 13 is a conveying platform, which is located below the folding mechanism 12, receives the finished paper bags conveyed downward by the front traction roller and the rear traction roller, and then delivers the finished paper bags.

[0028] As a further improved specific implementation, the second material storage mechanism 7 is also connected to a photoelectric calibration mechanism 14 for photoelectrically aligning the die-cutting position of the bag body.

[0029] As a further improved specific implementation, the die-cutting and creasing mechanism 5 is also connected with a hot stamping, printing and / or labeling mechanism in front, and is equipped with a calibration photoelectric eye, which is used for the die-cutting and creasing mechanism 5 to perform creasing and die-cutting after calibration.
