Preferably, the second alignment device 18 has the same structure as the first alignment device 14.
The working principle of the invention is shown in connection with fig. 3-4:
after the die-cut and creased paper blanks are loaded into the stock bin 13 (the bag mouth reinforcing sheet 1 and the alignment guide strip 1404 are positioned on the same side) in the step 000, the paper blanks in the stock bin are sent out in a single Zhang Shu mode by the paper conveying component 1301, wherein the paper conveying component 1301 can adopt a similar structure of the existing box pasting machine;
The blank then enters the first alignment device 14 in the direction shown as 001 where the downward facing side of the blank contacts the surface of the guide roller 1403 and the upward facing side is adjacent to a portion of the alignment bar 1404 that enters under the platen 1401 and contacts the steel ball 1402. Because the guide roller 1403 is all inclined in the direction of advance of the blank, the blank is always forced against the alignment bar 1404 by a force that pushes the blank forward as the guide roller rotates, causing the pocket reinforcement sheet 1 of the blank to always contact the sides of the alignment bar 1404, i.e., to abut against the sides of the alignment bar 1404 and advance along the alignment bar 1404, and the bottom surface of the plug sheet 12 is coated with glue by the first glue applicator 15 before the blank enters the pocket reinforcement sheet device 16;
as shown in 002, the bag mouth reinforcing sheet device 16 is used for folding the bag mouth reinforcing sheet 1 upwards and forming a double-layer structure at the bag mouth, at this time, the glue-coated surface of the inserting sheet 12 faces upwards, and when the paper blank is conveyed to the bag mouth reinforcing sheet device 16 due to the alignment effect of the first alignment device 14, the position of the bag mouth reinforcing sheet 1 is accurately consistent, the uniformity of the bag mouth reinforcing sheet 1 after being folded inwards is good, and the bag mouth reinforcing sheet device 16 can be used as a folding device similar to a box pasting machine;
as shown in 003, the paper blank is output from the bag opening reinforcing sheet device 16 into the pressing reinforcing sheet device 17, so that a double-layer structure at the bag opening enters between the upper edge pressing conveyor 1701 and the lower edge pressing conveyor 1702, and the double-layer structure is pressed to be more fit and compact in the conveying process, thereby facilitating the subsequent forming of the paper bag;
As shown in 004, the paper blank is output by the compaction reinforcing sheet device 17 and enters the second alignment device 18 under the inertia effect, wherein the second alignment device 18 and the first alignment device 14 have the same structure, and the alignment working principle is the same, namely, along with the rotation of the guide roller 1403 of the second alignment device 18, the outer side edge of the connecting sheet 11 contacts with the side surface of the alignment guide bar 1404 of the second alignment device 18, so that the position of the paper blank entering the cylinder forming device 21 is kept accurate, the placement direction of the paper blank is unchanged, but the conveying direction of the paper blank forms 90 degrees with the conveying direction of the compaction reinforcing sheet device 17, and the paper conveying is stable and the position is accurate;
As shown in 005, the paper blank is glued on the corresponding surfaces of the first side sheet 2 and the connecting sheet 11 by the second gluing device 19 and the third gluing device 20 respectively, and then the paper blank is further advanced to be adhered into a paper cylinder by the cylinder forming device 21 and the adhered part is compressed in the process of further advancing, wherein the cylinder forming device 21 can be a cylinder forming device of a box pasting machine.
As shown in 006, the paper tube continues to advance into the bag side inward folding device 22, and the first side piece 2 and the first side piece 7 are folded inwards to form an organ-shaped fold, so that the work of the subsequent process is convenient, wherein the bag side inward folding device 22 adopts the rims of two rows of guide wheels 2201 symmetrically arranged along the advancing direction of the paper tube to press the indentation positions of the first side piece 2 and the first side piece 7 on the bag tube inwards, so that the first side piece 2 and the first side piece 7 are folded inwards from the indentation positions to form the organ-shaped fold;
As shown in 007, the bag barrel after being folded by the organ enters a bag bottom opening device 23 to open the first side bottom sheet 3, the first side bottom sheet 6, the second side bottom sheet 8 and the second side bottom sheet 10 to form a bag blank, wherein the bag bottom opening device 23 can adopt a bottom hooking device of a box pasting machine;
the first side bottom sheet 3 and the second side bottom sheet 8 of the bag blank are folded inwards by the bag bottom folding device 24 as shown at 008, and the surfaces of the first side bottom sheet 3 and the second side bottom sheet 8 are respectively glued by the fourth gluing device 27 and the fifth gluing device 28 as shown at 009; turning the bag blank by 90 degrees by a turning device 25 to enable the indentation direction of the opened first surface bottom sheet 6 and the opened second surface bottom sheet 10 to be consistent with the travelling direction of the bag blank, and conveniently and inwards folding the first surface bottom sheet 6 and the second surface bottom sheet 10 to be bonded at a folding surface bottom device 26 to form a bag bottom until the paper stopping bag is formed as shown in 011, wherein a sixth gluing device 29 is further arranged before the folding surface bottom device 26 to glue the first surface bottom sheet 6 and the second surface bottom sheet 10, and the bag bottom folding device 24, the turning device 25 and the folding surface bottom device 26 can all adopt similar devices or mechanisms of a box pasting machine; the first glue applicator 15, the second glue applicator 19, the third glue applicator 20, the fourth glue applicator 27, the fifth glue applicator 28 and the sixth glue applicator 29 may all be gun or roller type glue applicators.
