[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, the specific structure of the utility model is: an aluminum foil bag edge folding and shaping mechanism, including a liftable material tray module 2, the material tray module 2 drives the vacuum aluminum foil bag thereon to descend, and is coordinated with a bag edge folding and shaping module 6, the bag edge folding and shaping module 6 is coordinated with a bag edge circular sticker feeding module 5, the bag edge folding and shaping module 6 includes a shaping movable structure 41, the shaping movable structure 41 is provided with a flipping and shaping movable seat 42, the flipping and shaping movable seat 42 is provided with a shaping pressing block 40 for pressing the side of the aluminum foil bag, a corner folding structure for folding the corners 90 degrees, and a side folding structure for folding the bag edge beyond the bottom of the aluminum foil bag to the bottom of the aluminum foil bag; the corner folding structure cooperates with the bag edge circular sticker feeding module 5 to absorb the circular sticker.

[0019] The specific steps of bag edge folding and shaping are as follows: First, Figure 1 The aluminum foil bag in step c is placed on the material tray module 2, and then the material tray module 2 drives the aluminum foil bag to descend to the bag edge folding station, and the folded and shaped seat 42 is driven to move by the shaping movable structure 41, thereby driving the shaping pressing block 40 to press the side of the aluminum foil bag, and then the corner is folded 90 degrees by the corner folding structure, and then the edge that exceeds the aluminum foil bag body is folded to the bottom of the aluminum foil bag by the edge folding structure, and then the round sticker is absorbed and pasted.

[0020] The corner folding structure includes a shaping rotating block 39 hinged on both sides of the shaping pressing block 40 and a shaping movable cylinder 47 arranged on the folding shaping movable seat 42, the shaping movable cylinder 47 is connected to the shaping movable block 48, the two shaping rotating blocks 39 are hinged with a shaping connecting arc rod 49, the other ends of the two shaping connecting arc rods 49 are hinged on the shaping movable block 48, and the shaping rotating block 39 is provided with an adsorption structure for adsorbing round stickers. The edge folding structure includes a folding shaft 43 and a folding motor 46 arranged on the folding shaping movable seat 42, the folding shaft 43 is connected to the folding motor 46 through a folding transmission structure 45, and a folding plate 44 is provided on the folding shaft 43.

[0021] When the above structure is subjected to bag edge folding and shaping, the bag edge folding and shaping is divided into 4 steps: the first step is that the shaping rotating block absorbs the sticker, specifically, the circular sticker 50 on the bag edge circular sticker feeding module 5 is absorbed by the adsorption structure on the shaping rotating block 39; the second step is that the bag edge corner is folded 90°, specifically, the shaping movable cylinder 47 drives the shaping movable block 48 to move, so that the shaping connecting arc rod 49 can drive the shaping rotating block 39 to rotate 90 degrees, thereby completing the 90-degree folding of the corner, The third step is to fold and shape the bag edge. Specifically, the folding motor 46 drives the folding transmission structure 45 to operate, and then drives the folding shaft 43 to rotate, so that the folding plate 44 can be driven to rotate accordingly, so that the bag edge that exceeds the aluminum foil bag can be folded to the bottom of the aluminum foil bag; the fourth step is to fit the bag edge corners to the long side of the vacuum packaging. This step specifically involves sticking the round sticker 50 sucked by the shaping rotating block 39 to the long side of the vacuum aluminum foil bag after completing the 90-degree folding of the corners.

[0022] like Figure 4 As shown, the bag along the circular sticker feeding module 5 includes a feeding module feeding cylinder 54, the feeding module feeding cylinder 54 is connected to the feeding module feeding seat, the feeding module feeding seat is provided with a sticker feeding roll 51, a waste paper tape recovery roll 52 and a guide cylinder, and the waste paper tape recovery roll 52 is equipped with a waste material rewinding motor 53, and the guide cylinder makes part of the paper tape with the circular sticker 50 in a vertical state.

[0023] Feeding process: The feeding cylinder 54 of the feeding module pushes the feeding module into the adsorption area, and the waste rewinding motor 53 drives the waste paper tape recovery roll 52 to rotate, so that the sticker feeding roll 51 can be unwound, and the paper tape with the round sticker 50 is in a vertical state. Then, the round sticker 50 is sucked up by the adsorption structure on the shaping rotary block 39, and then the feeding cylinder 54 pushes the feeding module out of the adsorption area to avoid interfering with the folding and shaping of the bag edge.
