DETAILED DESCRIPTION

[0039] 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.

[0040] like Figure 1-2 As shown, the specific structure of the present invention is: a vacuum aluminum foil bag packaging and shaping equipment, including a frame, a liftable material tray module 2 is provided on the frame 1, and it is characterized in that the material tray module 2 is matched with a pressing module 1, and the material tray module 2 drives the vacuum aluminum foil bag thereon to descend, and in the process of descending, it is matched with a four-side folding module 3, a corner folding module 4, a short bag edge folding and shaping module 6 and a long bag edge folding and shaping module 7 in sequence, the short bag edge folding and shaping module 6 is used for corner folding and short bag edge folding and shaping, the long bag edge folding and shaping module 7 is used for corner folding and long bag edge folding and shaping, the short bag edge folding and shaping module 6 and the long bag edge folding and shaping module 7 are respectively matched with a short bag edge circular sticker feeding module 5 and a long bag edge circular sticker feeding module 8.

[0041] The specific work is as follows: the aluminum foil bag filled with material and vacuumed is placed on the material tray module 2, and then the aluminum foil bag is pressed by the pressing module 1. Then the aluminum foil bag is driven by the material tray module 2 to move to the four-side folding station, and the four sides are folded by the four-side folding module 3 to obtain the following Figure 1 b, and then continue to descend to the folding station, and fold the four corners through the folding module 4 to obtain the following Figure 1 c state, then enter the bag edge folding and shaping station, through the short bag edge folding and shaping module 6 to perform 90-degree folding and short bag edge folding and shaping, through the long bag edge folding and shaping module 7 to perform 90-degree folding, such as Figure 1 d, and then the short bag edge folding and shaping module 6 is used to adhere the round stickers sucked from the short bag edge round sticker feeding module 5, as shown in FIG. Figure 1 As shown in FIGe, the long bag edge is then folded and fitted with the absorbed circular sticker to achieve the state shown in FIG1g. This completes the shaping of the vacuum aluminum foil bag, so that its edges and corners are well folded and shaped, almost like a rectangular parallelepiped, and then when it is placed in a foam cotton packaging box, it can reduce squeezing and interference, thereby reducing damage to the packaging box.

[0042] like Figure 3-5 As shown, the pressing module includes a pressing fixed frame 12, on which a pressing transverse movement cylinder 14 is provided, and the pressing transverse movement cylinder 14 is connected to a pressing lifting structure 13, and the pressing lifting structure is connected to a pressing plate 15; the four-side folding module includes a long bag edge folding plate assembly 16, a short bag edge folding plate assembly 17, a short bag edge folding plate assembly 2 18 and a long bag edge folding plate assembly 2 19 which are arranged below the pressing fixed frame 12 and are located on the four sides of the material tray module 2, and the four bag edge folding plate assemblies are all telescopic structures equipped with a folding pressure plate, and the material tray module 2 includes a tray lifting fixed seat 22, on which a tray lifting fixed seat 22 is installed a tray lifting screw rod 25, and the tray lifting screw rod 25 is equipped with a lifting drive motor 26, and the tray lifting screw rod 25 is sleeved with a tray lifting movable plate 24, and the tray lifting movable plate is connected to the material tray 20 through a tray lifting guide rod 23 that passes through the tray lifting fixed seat 22.

[0043] The vertical movement of materials is mainly completed by the cooperation of the above-mentioned pressing module and tray module; first, the pressing transverse movement cylinder 14 drives the pressing plate 15 and the pressing lifting structure 13 to move outward; then, the vacuum-packed aluminum foil bag is moved to the material tray 20. In order to accurately detect whether there is material on the material tray 20, a material detection sensor 21 will be installed on it, and then the pressing transverse movement cylinder 14 drives the pressing plate 15 and the pressing lifting structure 13 to move inward; so that the pressing plate 15 is above the aluminum foil bag, and then the pressing lifting structure 13 drives the pressing plate 15 to descend to press the aluminum foil bag, and the state is as follows Figure 5 As shown, the tray lifting screw 25 is then driven to rotate by the lifting drive motor 26, which can drive the tray lifting movable plate 24 to descend, and then drive the material tray 20 to descend. In order to better control the descent range, a lifting positioning sensor 27 can be installed to sense the range of the tray lifting movable plate 24; while the material tray 20 descends, the pressing lifting structure 13 drives the pressing plate 15 to descend synchronously. When it descends to the folding station, the four sides of the aluminum foil bag are folded through the long bag along folding plate assembly 16; the short bag along folding plate assembly 17; the short bag along folding plate assembly 2 18 and the long bag along folding plate assembly 2 19.

[0044] like Figure 6-8 As shown, there are two groups of corner folding modules 4, which are located on both sides of the short side of the aluminum foil bag carried by the material tray module 2. The corner folding module 4 includes a corner folding mounting seat 35, and a corner folding movable cylinder 36 is provided on the corner folding mounting seat 35. The corner folding movable cylinder 36 is connected to the corner folding movable seat, and the corner folding movable seat is provided with a finger clamping cylinder 1 30 and a finger clamping cylinder 2 32. The finger clamping cylinder 1 30 drives the two finger clamps 1 31 to move together and apart, and the finger clamping cylinder 2 32 drives the two finger clamps 2 33 to move together and apart.

[0045] Corner folding process: First, the corner folding movable seat is driven to move by the corner folding movable cylinder 36, and the clamping fingers are withdrawn from the corner folding area; when the vacuum packaging material enters the corner folding area, the corner folding movable cylinder 36 will drive the corner folding movable seat to move, and then the clamping fingers enter the corner folding area; then the clamping finger cylinder 30 and the clamping finger cylinder 2 32 respectively drive the clamping fingers 1 31 and 2 33 to tighten, and then clamp the bag body; finally, the corner folding movable seat is driven to move by the corner folding movable cylinder 36, and then the clamping fingers are pulled out to complete the folding forming of the corner (such as Figure 8 shown).

[0046] The short bag edge folding and shaping module 6 and the long bag edge folding and shaping module 7 both include a shaping movable structure 41, a flipping and shaping movable seat 42 is provided on the shaping movable structure 41, and 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; wherein the corner folding structure of the short bag edge folding and shaping module 6 cooperates with the short bag edge circular sticker feeding module 5 to absorb the circular sticker; the side folding structure of the long bag edge folding and shaping module 7 cooperates with the long bag edge circular sticker feeding module 9 to absorb the circular sticker.

[0047] The specific steps of folding and shaping the bag edge are as follows: first, the shaping movable structure 41 drives the folded and shaped seat 42 to move, and then drives the shaping pressing block 40 to press the side of the aluminum foil bag, and then the corner folding structure is used to fold the corner 90 degrees, and then the edge folding structure is used to fold the edge that exceeds the aluminum foil bag body to the bottom of the aluminum foil bag, and then the round sticker is absorbed and pasted.

[0048] 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, and 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 of the short bag edge folding shaping module 6 is provided with an adsorption structure for adsorbing circular stickers, and 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, and an adsorption structure for adsorbing circular stickers is provided on the folding plate 44 of the long bag edge folding shaping module 7.

[0049] When the above structure is subjected to short bag edge folding and shaping, the short 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 short 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 short 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 the short bag edge folding and shaping, 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 short bag edge exceeding the aluminum foil bag can be folded to the bottom of the aluminum foil bag (such as Figure 12 As shown); the fourth step is to fit the short bag along the corners to the long side of the vacuum packaging. Specifically, this step involves attaching the round sticker 50 sucked by the shaping turn block 39 to the long side of the vacuum aluminum foil bag after the corners are folded 90 degrees.

[0050] like Figure 9 As shown, the short 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.

[0051] 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 short bag edge.

[0052] When the long bag edge is folded and formed by the above structure, it is also necessary to cooperate with the long bag edge folding and shaping module 7. The long bag edge folding and shaping module 7 is coordinated with the long bag edge inner folding module 8. The long bag edge inner folding module 8 folds the long bag edge after the corner folding structure completes the 90-degree folding of the corner. The long bag edge inner folding module 8 includes a horizontally arranged long bag edge folding cylinder 57, and the long bag edge folding cylinder 57 is connected to a folding push rod 58.

[0053] The specific steps are as follows Figure 13-16 As shown, the folding shaping of the long bag is divided into 5 steps: the first step is to absorb the sticker by the folding plate, specifically, the folding motor 46 drives the folding transmission structure 45 to operate, and then drives the folding shaft 43 to rotate to keep it vertical, and then the adsorption structure on it adsorbs the round sticker 50 on the long bag round sticker feeding module 8 (as shown in FIG. Figure 13 As shown); the second step is to fold the long bag 90 degrees along the corners, specifically by driving the shaping movable block 48 to move through the shaping movable cylinder 47, 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 corners (as shown in FIG. Figure 14 As shown), the third step is the inner folding, specifically, the long bag along the folding cylinder 57 drives the folding push rod 58 to extend toward the inner side of the long bag, and the long bag along the folding is a triangular bag edge (as shown in FIG. Figure 15 As shown), the folded effect is as follows Figure 1 f shown; The fourth step is to fold and shape the long bag edge and stick the sticker, 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 long bag edge that exceeds the aluminum foil bag and is folded inward can be folded to the bottom of the aluminum foil bag, and the round sticker absorbed by the adsorption structure on the folding plate 44 is stuck to the bottom of the vacuum aluminum foil bag (such as Figure 16 shown).

[0054] The general structure of the long bag round sticker feeding module 8 is consistent with that of the short bag round sticker feeding module 5. The conveying angle of the round stickers can be adjusted according to specific needs.
