[0031] Please refer to Figure 3 、 Figure 6 As shown in the figure, the present utility model is an anti-crease film covering device for the production of aluminum foil bags, including a film covering table 1. A mounting frame 2 is fixedly installed on the top of the film covering table 1. A film roller 3 and a rubber roller 4 are respectively arranged on the inner wall of the mounting frame 2. An unwinding assembly 5 is fixedly installed on the outer surface of the film covering table 1. A lifting device 6 is arranged inside the mounting frame 2. A film pressing assembly 7 is rotatably installed at the bottom of the lifting device 6. An inner through groove 8 is opened inside the mounting frame 2. One side of the lifting device 6 is slidably connected to the inner wall of the inner through groove 8. A driving device 9 is arranged inside the inner through groove 8. The output end of the driving device 9 is engaged with one end of the film pressing assembly 7. A flat pressing assembly 10 is rotatably installed on the outer surface of the mounting frame 2.

[0032] When it is necessary to laminate an aluminum foil bag, the film roller 3 and the rubber roller 4 are respectively mounted on the inner wall of the mounting frame 2, and the film on the film roller 3 is drawn above the rubber roller 4 and extends along the bottom of the film pressing assembly 7 to the other side of the laminating table 1. After the film adheres to the surface of the rubber roller 4, the end of the aluminum foil layer on the unwinding assembly 5 is drawn onto the laminating table 1. At this time, the flat pressing assembly 10 is driven to rotate and approach above the side of the aluminum foil layer close to the unwinding assembly 5. At the same time, the lifting device 6 is started to descend inside the mounting frame 2 and drive the film pressing assembly 7 to move downward until the end of the film pressing assembly 7 is close to meshing with the output end of the driving device 9 and then stops. After the film pressing assembly 7 is close to the laminating table 1, the driving device 9 is started to operate and drive the film pressing assembly 7 to operate, so as to drive the film and the aluminum foil layer to move forward and adhere together on the laminating table 1. When the flat pressing assembly 10 operates together at the input end of the aluminum foil layer to roll and press its surface, at the same time, it cooperates with the film pressing assembly 7 to roll and convey the film and the aluminum foil layer after being glued.

[0033] In the utility model, by arranging the lifting device 6 inside the mounting frame 2, when the aluminum foil layer needs to be laminated, the film pressing assembly 7 is driven to descend through the lifting device 6 so that it is close to and adheres to the top of the laminating table 1. At the same time, after the aluminum foil layer is drawn onto the laminating table 1, it can cooperate with the flat pressing assembly 10 to roll and flatten the aluminum foil layer, so that when it is conveyed in the direction of the film pressing assembly 7, its top has a certain pressing effect and maintains flatness. Furthermore, when it is compounded with the film below the film pressing assembly 7, it can cooperate with the film pressing assembly 7 to roll and compound it again and drive the conveying effect, preventing wrinkles from occurring on its surface during the lamination operation and affecting the lamination production quality.

[0035] The top roller 11 is located above the rubber roller 4. When the film is output from the film roller 3, it passes between the rubber roller 4 and the top roller 11. The top roller 11 can extrude the passing film so that the film can adhere sufficient colloid on the surface of the rubber roller 4. By arranging the winding roller 14 on one side of the mounting frame 2, when the film and the aluminum foil layer are compounded and output, the driving motor 13 drives the winding roller 14 to operate on the inner wall of the side bracket 12, so as to quickly wind up the compounded aluminum foil layer.

[0036] In one embodiment, for the above-mentioned lifting device 6, the lifting device 6 includes a driving gear 601. One side of the driving gear 601 is engaged with a lifting toothed plate 602, and one end of the driving gear 601 is fixedly installed with a driving rotating rod 603.

[0037] The driving rotating rod 603 extends to the outside of the mounting frame 2. By rotating the driving rotating rod 603, the driving gear 601 is operated to drive the lifting toothed plate 602 to slide and displace along the inside of the inner through groove 8, thereby driving the film pressing assembly 7 at its bottom to descend.

[0038] In one embodiment, for the above-mentioned film pressing assembly 7, the film pressing assembly 7 includes a film pressing roller 701. One end of the film pressing roller 701 is fixedly installed with a connecting shaft 702, and one end of the connecting shaft 702 is fixedly installed with a transmission gear 703. The transmission gear 703 is engaged with the output end of the driving device 9.

[0039] When the lifting toothed plate 602 is driven to displace, the film pressing roller 701 at its bottom gradually descends and approaches the top surface of the film covering table 1. Until the film pressing roller 701 is close to fitting the top of the film covering table 1, the lifting toothed plate 602 stops displacing. At this time, after the driving device 9 is started, it drives the transmission gear 703 to rotate to drive the connecting shaft 702 and the film pressing roller 701 to rotate. When the aluminum foil layer and the film pass through its bottom surface, the film pressing roller 701 has a certain pressure on the film so that the aluminum foil layer and the film are adhered together.

[0040] In one embodiment, for the above-mentioned driving device 9, the driving device 9 includes a driving motor 901. The output end of the driving motor 901 is fixedly installed with a second driving gear 902. The second driving gear 902 is engaged with the transmission gear 703.

[0041] When the lifting toothed plate 602 is driven to displace by the driving gear 601 and drives the film pressing roller 701 to descend onto the film covering table 1, after the second driving gear 902 approaches the transmission gear 703, by starting the driving motor 901, the second driving gear 902 rotates to drive the transmission gear 703 to rotate, and further drives the film pressing roller 701 to operate on the top of the film covering table 1.

[0042] By placing the driving gear 601 and the lifting toothed plate 602 inside the inner through groove 8 and extending the film pressing roller 701 outside the inner through groove 8, this cooperation can provide a lifting driving force for the film pressing roller 701. When laminating the aluminum foil bag, it can be lowered to a position close to the top surface of the film covering table 1. And in cooperation with the driving motor 901 and the second driving gear 902, it can provide a running driving force for the film pressing roller 701, so that the film pressing roller 701 can provide a pressing and flattening effect during the laminating process of the aluminum foil bag, reducing the occurrence of wrinkles when the aluminum foil bag is laminated.

[0043] In one embodiment, for the above-mentioned film pressing roller 701, a rotating shaft 704 is fixedly installed at the other end of the film pressing roller 701. A guide slider 705 is arranged on the outer surface of the rotating shaft 704. A guide chute 15 is formed on one side of the inner wall of the mounting frame 2. The guide slider 705 is slidably connected to the inner wall of the guide chute 15.

[0044] The rotating shaft 704 at the other end of the film pressing roller 701 extends into the interior of the guide chute 15 and is connected to the guide slider 705. When one end of it is driven to descend by the lifting rack 602, the other end can slide along with the displacement path on the inner wall of the guide chute 15.

[0045] In one embodiment, for the above-mentioned unwinding assembly 5, the unwinding assembly 5 includes an unwinding frame 501, and an unwinding roller 502 is rotatably installed on the inner wall of the unwinding frame 501.

[0046] By arranging the unwinding frame 501 in front of the film laminating table 1, a certain support height can be provided for the unwinding roller 502, so that the aluminum foil bag has a certain support tension during film lamination.

[0047] In one embodiment, for the above-mentioned flat pressing assembly 10, the flat pressing assembly 10 includes a fixing plate 1011, and a flat pressing rod 1012 is rotatably installed on the inner wall of the fixing plate 1011. A rotating motor 1013 is fixedly installed at one end of the flat pressing rod 1012.

[0048] The flat pressing rod 1012 is composed of multiple groups of thin rods to form a surrounding flat pressing rod 1012. When the aluminum foil layer passes over the top of the film laminating table 1, its rotating motor 1013 drives the flat pressing rod 1012 to rotate, so that each group of rods in it operates alternately to roll and flatten the aluminum foil layer without interfering with its conveying speed.

[0049] Through the above technical solutions: 1. By arranging the lifting device 6 inside the mounting frame 2, when the aluminum foil layer needs to be laminated, the pressing film assembly 7 is driven by the lifting device 6 to descend so as to be close to the top of the laminating table 1. At the same time, after the aluminum foil layer is drawn onto the laminating table 1, the flat pressing assembly 10 can be used to roll and flatten the aluminum foil layer, so that when it is conveyed towards the pressing film assembly 7, its top has a certain pressing effect and remains flat. Furthermore, when it is compounded with the film below the pressing film assembly 7, the pressing film assembly 7 can be used to roll and compound it again and drive the conveying effect, preventing wrinkles from occurring on its surface during the lamination operation and affecting the lamination production quality; 2.
