When the sheet conveying device works, a punched and cut sheet 18 is conveyed to the sheet clamping mechanism 7 through the sheet feeding device 3, then the sheet 18 is clamped and conveyed into the limiting groove 8 through the sheet clamping mechanism 7, and as the limiting groove 8 corresponds to the supporting plate 21 passing below the limiting groove 8, the sheet 18 in the limiting groove 8 can be aligned with the supporting plate 21 on the sheet conveying belt 2, so that the sheet 18 can be accurately placed on the supporting plate 21; then, the sheet conveyer belt 2 conveys the sheet 18 on the pallet 21 to the lower part of the sheet suction device 4, and the sheet suction device 4 sucks the sheet 20 (i.e. advertisement page) and places the sheet on the inner side of the lower sheet of the sheet 18; the sheet 18 and the paper 20 thereon are conveyed to the primary heat sealing device 53 along with the sheet conveyer belt 2, the film on the film discharging device 11 is discharged, the film is sequentially clamped by the first film clamping mechanism 12 and the second film clamping mechanism 13, when the film is conveyed to the upper surface of the film bottom plate 27, the piston rod of the film suction cylinder 521 extends downwards to drive the vacuum suction plate 522 to descend and adsorb the film on the film bottom plate 27, at the same time, the cutter device 14 cuts the film into the film 19, the film 19 which is adsorbed and cut off moves through the film suction horizontal reciprocating mechanism 51 to move the film 19 below the primary heat sealing device 53 and above the lower sheet of the sheet 18 and the paper 20 thereon, the vacuum suction plate 522 releases the film 19 to enable the film 19 to cover the inner side surface of the lower sheet of the sheet 18 and wrap the paper 20 between the film 19 and the lower sheet of the sheet 18, after the film sucking cylinder 521 is driven by the film sucking horizontal reciprocating mechanism 51 to reset, the primary heat sealing device 53 descends to seal two continuous side edges of the film 19 on the inner side surface of the lower sheet of the sheet 18 to form a first sealing line and a second sealing line (the first sealing line and the second sealing line form an L-shaped heat sealing line); finally, the sheet 18, the paper sheet 20 thereon and the membrane 19 are conveyed to the lower part of the secondary heat sealing device 6 by the sheet conveyer belt 2, the third side edge of the membrane 19 is sealed on the inner side surface of the lower sheet of the sheet 18 by the secondary heat sealing device 6 to form a third sealing line, so that a page inserting bag with an opening is formed between the fourth side edge of the membrane 19 and the lower sheet, and at the moment, the paper sheet 20 is already in the page inserting bag in advance, and the paper sheet 20 does not need to be manually placed in the page inserting bag. The packaging machine for inserting the advertising page into the file pocket can seal and package the plate 18, the paper sheet 20 and the membrane 19 automatically, simplifies the manufacturing process, improves the production efficiency, and accords with the concepts of automatic production and safety production.
