[0002] Paper aluminum bag is a composite packaging bag composed of base paper, aluminum foil and polyethylene. Its structure includes three layers: base paper layer, aluminum foil layer and polyethylene layer. The main function of the aluminum foil layer is to prevent moisture, gas and light, while the base paper layer reduces the weight of the bag and improves the appearance.

[0044] like Figure 5 and Fig.11 As shown, the discharge assembly 9 includes a side plate 901 fixedly connected to the support plate 2, a third drive motor 902 is fixedly connected to the side plate 901, an output shaft of the third drive motor 902 is fixedly connected to a driving bevel gear 903, an internal movable sleeve of the side plate 901 is provided with a movable shaft 904, an external fixed sleeve of the movable shaft 904 is provided with a driven bevel gear 905, and the driving bevel gear 903 is meshed with the driven bevel gear 905 for transmission, both ends of the movable shaft 904 are fixedly connected with brackets 906, a placement groove 907 is provided on the top of the bracket 906, a bearing 908 is provided inside the movable sleeve of the placement groove 907, and the bearing 908 A discharge roller 909 is sleeved inside the bracket 906, and an electromagnet 910 fixedly sleeved inside the bracket 906 is provided below the placement groove 907. The third drive motor 902 drives the driven bevel gear 905 meshing with it to rotate through the active bevel gear 903, and the driven bevel gear 905 drives the movable shaft 904 to rotate, and the movable shaft 904 drives the bracket 906 to rotate. When the bracket 906 rotates vertically, it is convenient for the paper aluminum bag roll to roll onto the bracket 906, and the electromagnet 910 is used to absorb the bearing 908 for positioning, so that there is no need for lifting or moving, and then the bracket 906 is rotated horizontally, so that the paper aluminum bag roll can be lifted for use.

[0045] like Fig.11 As shown, the bracket 906 is an F-shaped structure, a mounting hole for the bracket 906 is provided below the placement slot 907, and the electromagnet 910 is fixedly sleeved in the mounting hole.

[0046] like Fig. 9 As shown, limiting grooves are provided on both sides of the horizontal plate 702, and the limiting rods 703 are movably sleeved in the limiting grooves, and the limiting rods 703 are lifted and lowered in the limiting grooves.

[0047] like Figure 8 As shown, a lifting groove is provided on one side of the mounting plate 601, and a lifting plate 607 is slidably arranged in the lifting groove, and the lifting plate 607 can be lifted and lowered along the lifting groove.

[0048] like Figure 8As shown, a feeding port is provided on the top of the glue box 613 , and a solenoid valve is provided on the hose 614 . Closing the solenoid valve prevents glue from leaking out, and the feeding port can be used to replenish glue in the glue box 613 .

[0049] Working principle: Roll the uncut wide paper aluminum bag roll onto the vertical bracket 906, and use the electromagnet 910 to absorb the bearing 908 for positioning, so that there is no need for lifting or moving. Then the third drive motor 902 drives the driven bevel gear 905 meshing with it to rotate through the active bevel gear 903, and the driven bevel gear 905 drives the movable shaft 904 to rotate, and the movable shaft 904 will drive the bracket 906 to rotate horizontally, so that the paper aluminum bag roll can be lifted for use. The paper aluminum bag roll is guided by the guide roller 3. At this time, the slitting knife 606 cuts the paper aluminum bag, and the first drive motor 504 drives the material reel 507 to rotate through the plug-in plate 506 and the plug-in slot 508, so that the material reel 507 can rewind the paper aluminum bag that has been cut. After rewinding, the second drive motor 611 drives the gear column 612 to rotate, and the gear column 612 drives the first rack 603 and the second rack 609 meshing therewith to rotate, and the first rack 603 and the second rack 609 are displaced up and down, thereby driving the slitting knife 606 and the first long cutting knife 610 to be displaced up and down, so that the slitting knife 606 rises and the first long cutting knife 610 moves down to work, and the first push rod motor 608 also drives the first long cutting knife 610 to move back and forth, which is convenient for the first long cutting knife 610 to move back and forth to achieve fast cutting, and when the first long cutting knife 610 moves down for cutting, it also drives the spray pipe 615 to move down for glue spraying, and the delivery pump in the glue tank 613 delivers glue into the spray pipe 615 through the hose 614, and the spray pipe 615 glues the incision after cutting the paper aluminum bag to prevent the paper aluminum bag roll from loosening and being scattered.

[0050] When the packaging machine needs an aluminum bag roll for use, the paper aluminum bag roll and the material reel 507 at the first drive motor 504 can be transferred to the double-axis motor 505 together. Since the plug-in slot 508 adopts a U-shaped structure, the material reel 507 can be directly removed from the plug-in plate 506, so there is no need to go to the warehouse to get the paper aluminum bag roll, and it can be cut and used at the same time. When using it, it is necessary to first cut off the part of the end of the paper aluminum bag roll that is stained with glue. Then, the double-axis motor 505 drives the material reel 507 to rotate through the plug-in plate 506 and the plug-in slot 508, so that the paper aluminum bag roll on the material reel 507 can be released for packaging. The use of the installation, and the dual-axis motor 505 also drives the disc 509 to rotate. When the disc 509 rotates, it will always be close to the proximity switch 706, so that the proximity switch 706 controls the output shaft of the second push rod motor 707 to retract. Since a part of one side of the disc 509 is cut off, the cut part of the disc 509 is away from the proximity switch 706. At this time, the proximity switch 706 controls the output shaft of the second push rod motor 707 to extend, and the second push rod motor 707 drives the second long cutting knife 708 to move downward to cut the paper aluminum bag at an equal distance, and the first pressing roller 705 relies on its own gravity to press the paper aluminum bag roll tightly to prevent it from jumping during rotation.
