Description

Technical Field

[0001] The invention relates to the technical field of packaging box processing equipment, in particular to a packaging box feeding and folding mechanism. Background Art

[0002] Before leaving the factory, products need to be packaged in boxes to improve the appearance of the goods and attract customers to buy. The packaging box is generally a hollow cubic structure with openings at both ends. The openings at both ends are respectively provided with a front cover and a back cover to seal the openings at both ends.

[0003] The box body of the packaging box is generally composed of an upper side panel, a lower side panel, a left side panel and a right side panel, and the back cover of the packaging box is generally composed of an upper cover, a lower cover, a left cover and a right cover folded together. When folding the back cover, the incoming material is generally a flat packaging box, that is, there is no obvious crease between the lower side panel and the left side panel and between the upper side panel and the right side panel of the packaging box (or between the upper side panel and the left side panel and between the lower side panel and the right side panel of the packaging box). If the packaging box is made of a harder material (such as kraft paper), the back cover will rebound after being folded in a normal box folding method, making it impossible for the packaging box to maintain a stable hollow cube shape, which will not only affect the folding of the back cover, but also affect the performance and aesthetics of the packaging box.

[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequence or order.

[0032] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the present invention are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed in the present invention.

[0033] The packaging box feeding and folding mechanism provided in the embodiment of the present invention is used to feed, load, open (opening means turning the flat packaging box 9 into a three-dimensional structure), fold, and perform other operations on the packaging box 9. For ease of understanding, before describing the packaging box feeding and folding mechanism, the structure of the packaging box 9 and its form before, during, and after folding are first introduced below: like Figure 10 to Figure 11c As shown, the box body of the packaging box 9 includes an upper side plate 9A, a lower side plate 9B, a left side plate 9C and a right side plate 9D. The upper side plate 9A and the lower side plate 9B are arranged opposite to each other in vertical direction, the upper side plate 9A is located above the lower side plate 9B, and the left side plate 9C and the right side plate 9D are arranged opposite to each other in horizontal direction. The box body of the packaging box 9 is provided with openings on the front and back sides. The front opening is provided with a front cover (not numbered in the figure. The present invention does not involve the folding of the front cover, so it will not be described in detail), and the rear opening is provided with a rear cover 91. The rear cover 91 is formed by folding an upper cover 912, a lower cover 911, a left cover 913 and a right cover 914. The upper cover 912 and the lower cover 911 are arranged opposite to each other in vertical direction, the upper cover 912 is located above the lower cover 911, and the left cover 913 and the right cover 914 are arranged opposite to each other in horizontal direction. As shown Fig.11b and Fig.11c As shown, when the back cover 91 is folded into shape, the lower cover 911 is generally folded upward first, and then the left cover 913 is folded to the right and the right cover 914 is folded to the left, so that the left cover 913 and the right cover 914 are placed on the lower cover 911, and then the upper cover 912 is folded downward so that the left and right sides of the upper cover 912 are placed on the left cover 913 and the right cover 914 respectively, and finally the upper cover 912 (specifically the lower end of the upper cover 912) is pressed and folded to (inserted into) between the lower cover 911, the left cover 913 and the right cover 914, thereby completing the folding of the back cover 91.

[0034] Among them, Fig.11a and Fig.10 As shown in state 1 in the figure, before the back cover 91 is folded, since the incoming packaging box 9 (that is, the packaging box 9 to be processed described below) is a flat structure, that is, at this time, the upper side plate 9A and the lower side plate 9B of the packaging box 9 are close to or abut against each other, and an obvious crease 90 is formed between the upper side plate 9A and the left side plate 9C of the packaging box 9 and between the lower side plate 9B and the right side plate 9D (that is, the crease 90 is deeper), and no obvious crease 90 is formed between the lower side plate 9B and the left side plate 9C of the packaging box 9 and between the upper side plate 9A and the right side plate 9D (that is, the crease 90 is shallow or even no crease 90 is formed. In other embodiments, obvious creases 90 may be formed between the lower side plate 9B and the left side plate 9C of the packaging box 9 and between the upper side plate 9A and the right side plate 9D, while no obvious crease 90 is formed between the upper side plate 9A and the left side plate 9C of the packaging box 9 and between the lower side plate 9B and the right side plate 9D). If the packaging box 9 is made of a harder material (such as kraft paper), according to the conventional box folding method, after the packaging box 9 is opened (that is, the packaging box 9 is opened into a cubic shape), the back cover 91 is directly folded, then the packaging box 9 will return to a flat state under the elastic force of its own material, which not only makes it impossible for the packaging box 9 to maintain a stable hollow cubic shape, but also affects the folding of the back cover 91, that is, the back cover 91 automatically opens after being folded, affecting the production efficiency and yield.

[0035] Therefore, if Fig.10 As shown, in this embodiment, when the packaging box 9 is opened, the packaging box 9 is also reversed and pressed, that is, the packaging box 9 is reversed to a folded state (that is, the packaging box 9 is Fig.10 The left folded state shown in the middle state 1 is turned over to the right folded state shown in the state 2) and then pressed together, so that obvious folds 90 are also formed between the lower side plate 9B and the left side plate 9C of the packaging box 9 and between the upper side plate 9A and the right side plate 9D. When the pressure on the packaging box 9 is removed, the packaging box 9 can bounce up under the elastic force of its own material and form a hollow cube shape (that is, the packaging box 9 is formed by the hollow cube shape). Fig.10The state 2 in the packaging box is changed into the state 3), so as to facilitate the subsequent folding of the rear cover 91. After the packaging box 9 is turned over and pressed into shape, the packaging box 9 can be Fig.11a The state shown changes to Fig.11b Status shown.

[0036] like Figures 1 to 11c As shown, the packaging box feeding and folding mechanism provided in the embodiment of the present invention is used to open the packaging box 9 and fold the back cover 91 of the packaging box 9. The packaging box 9 is not limited to an inner box, an outer box, etc., and the material of the packaging box 9 includes but is not limited to kraft paper, etc. The packaging box feeding and folding mechanism has a left-right direction X and a front-back direction Y that are perpendicular to each other, and includes a base 1, a feeding mechanism 2, a feeding mechanism 3, a transplanting mechanism 4, a pressure protection mechanism 5, a box opening mechanism 6 and a cover folding mechanism 7. The feeding mechanism 2, the feeding mechanism 3, the transplanting mechanism 4, the pressure protection mechanism 5, the box opening mechanism 6 and the cover folding mechanism 7 are all arranged on the base 1; the feeding mechanism 2 is used to temporarily store the packaging box 9 to be processed (the packaging box 9 is in a flat state at this time).

[0037] The transplanting mechanism 4 is provided with a plurality of workstations, including a loading station 4A, a box opening station 4B and a box folding station 4C which are sequentially arranged along the left-right direction X. The loading mechanism 3 is used to transfer the packaging box 9 on the feeding mechanism 2 to the loading station 4A of the transplanting mechanism 4; the transplanting mechanism 4 is used to transfer the packaging box 9 from the loading station 4A to the box opening station 4B, and to transfer the packaging box 9 from the box opening station 4B to the box folding station 4C.

[0038] The pressure protection mechanism 5 is located above the transplanting mechanism 4, and the pressure protection mechanism 5 includes a pressing mechanism 52 and a folding cover mechanism 53. The pressing mechanism 52 and the box opening mechanism 6 are both arranged corresponding to the box opening station 4B, and the folding cover mechanism 53 is arranged corresponding to the box folding station 4C; the box opening mechanism 6 is used to open and flip the flat packaging box 9 (in this embodiment, the packaging box 9 is specifically flipped 180°), and the pressing mechanism 52 is used to press (press) the flipped packaging box 9 from top to bottom so that the flat packaging box 9 can be flipped and pressed into a three-dimensional structure (i.e., a hollow cubic structure).

[0039] A folding cover member 41 is provided on the transplanting mechanism 4; the folding cover mechanism 7 is provided corresponding to the box folding station 4C, and the folding cover mechanism 7 includes a left cover folding mechanism 71, a right cover folding mechanism 72 and a cover pressing mechanism 73; the folding cover member 41 is used to fold the lower cover 911 of the packaging box 9 upwards, the left cover folding mechanism 71 is used to fold the left cover 913 of the packaging box 9 to the right, the right cover folding mechanism 72 is used to fold the right cover 914 of the packaging box 9 to the left, the folding cover mechanism 53 is used to fold the upper cover 912 of the packaging box 9 downwards, and the cover pressing mechanism 73 is used to press the upper cover 912 to between the lower cover 911, the left cover 913 and the right cover 914, so as to fold the rear cover 91.

[0040] The packaging box feeding and folding mechanism provided in the embodiment of the present invention is provided with a feeding mechanism 2, a feeding mechanism 3, a transplanting mechanism 4, a pressure protection mechanism 5, a box opening mechanism 6 and a cover folding mechanism 7. The pressure protection mechanism 5 includes a pressing mechanism 52 and a cover folding mechanism 53. The transplanting mechanism 4 is provided with a folding cover 41. The cover folding mechanism 7 includes a left cover folding mechanism 71, a right cover folding mechanism 72 and a cover pressing mechanism 73. Among them, the feeding mechanism 2 and the feeding mechanism 3 can realize the feeding and loading of the packaging box 9, and the transplanting mechanism 4 can realize the packaging box 9 at the feeding station 4A and the box opening station The box opening mechanism 6 can be switched between the box opening station 4B and the box folding station 4C, and the box opening mechanism 6 can cooperate with the pressing mechanism 52 to turn and press the box 9, so that the box 9 can maintain a stable hollow cube shape, which solves the problem of the box 9 made of a harder material rebounding after opening, which is not only convenient for the subsequent folding and forming of the rear cover 91, but also conducive to improving the use performance and aesthetics of the box 9; the folding cover 41, the folding cover mechanism 53, the folding left cover mechanism 71, the folding right cover mechanism 72 and the pressing cover mechanism 73 can cooperate to fold the rear cover 91. The box feeding and folding mechanism can stably and reliably feed and fold the box 9, thereby improving the production yield and production efficiency of the box 9.

[0041] like Figure 1 and Figure 2 As shown, as an embodiment, the feeding mechanism 2 is located on one side of the transplanting mechanism 4 along the front-to-back direction Y, and the feeding mechanism 2 includes a plurality of independent storage mechanisms 20 (i.e., the plurality of storage mechanisms 20 can be fed separately without affecting each other), and the plurality of storage mechanisms 20 are arranged in sequence along the left-right direction X. Each storage mechanism 20 includes a trough 21, a tray 22 and a lifting mechanism 23, the tray 22 is arranged in the trough 21, the trough 21 is used to place the packaging box 9 to be processed, and the tray 22 is used to push the packaging box 9 in the trough 21 upward.

[0042] The trough 21 is slidably connected to the base 1 (specifically, it can be connected through a slide rail), and a handle 211 is provided on one side of the trough 21. Pulling the handle 211 can drive the trough 21 to move forward and backward relative to the base 1. The lifting mechanism 23 is provided on the base 1 (the lifting mechanism 23 is fixedly connected to the base 1) and is located below the trough 21. The lifting mechanism 23 is connected to the tray 22. The lifting mechanism 23 is used to drive the tray 22 to move up and down in the trough 21, so that the tray 22 can push the packaging box 9 in the trough 21 upward, and the lifting mechanism 23 can drive the tray 22 to move below the trough 21.

[0043] Specifically, in this embodiment, there are two storage mechanisms 20, which are arranged side by side along the left-right direction X (of course, in other embodiments, there may be more storage mechanisms 20). The lifting mechanism 23 is a motor screw assembly, the motor is fixedly connected to the base 1, and the screw is fixedly connected to the tray 22; when the lifting mechanism 23 drives the tray 22 to move upward, the packaging box 9 in the trough 21 will fall on the tray 22 and be pushed upward by the tray 22, so as to facilitate the feeding mechanism 3 to absorb the packaging box 9 on the tray 22. Among them, the upper and lower sides of the trough 21 are provided with openings, the upper opening is used for the feeding mechanism 3 to absorb the packaging box 9 on the tray 22, and the lower opening is used for the tray 22 to move below the trough 21. During operation, when all the packaging boxes 9 in the trough 21 are taken out, the lifting mechanism 23 drives the tray 22 to move to the bottom of the trough 21 (to avoid interference with the trough 21 when the trough 21 slides), and then pulls the handle 211 to pull out the entire trough 21 for feeding, and pushes the trough 21 back to its original position after feeding. Since the embodiment is provided with a plurality of mutually independent storage mechanisms 20, and the storage mechanisms 20 are fed by pulling out the trough 21, the equipment does not need to be stopped when feeding the storage mechanisms 20, which is conducive to improving production efficiency.

[0044] like Figure 1 and Figure 2 As shown, as an embodiment, the feeding mechanism 3 includes a lateral movement module 31 arranged on the base 1, a left and right telescopic module 32 connected to the lateral movement module 31, an upper and lower telescopic module 33 connected to the left and right telescopic module 32, and a first suction cup 34 arranged on the upper and lower telescopic module 33, the first suction cup 34 is used to suck the packaging box 9 on the tray 22, and the upper and lower telescopic module 33 is used to drive the first suction cup 34 to move up and down so that the first suction cup 34 can suck the packaging box 9 on the tray 22; the left and right telescopic module 32 is used to drive the upper and lower telescopic module 33 to move along the upper and lower telescopic module 33. The lateral movement module 31 is used to drive the left and right telescopic modules 32 to move along the front-to-back direction Y, thereby driving the left and right telescopic modules 32, the upper and lower telescopic modules 33 and the first suction cup 34 to move along the front-to-back direction Y, so that the first suction cup 34 can reach the loading station 4A and place the packaging box 9 sucked by the first suction cup 34 at the loading station 4A.

[0045] Specifically, in this embodiment, the lateral movement module 31 is a linear guide module, and the lateral movement module 31 is fixed to the base 1 through the first leg 35; the left and right telescopic modules 32 and the upper and lower telescopic modules 33 are cylinders. When working, the upper and lower telescopic modules 33 drive the first suction cup 34 to suck the packaging box 9 in one of the storage mechanisms 20 (multiple packaging boxes 9 will be stacked in the storage mechanism 20, and the first suction cup 34 sucks the packaging box 9 on the top layer in the storage mechanism 20), and the lateral movement module 31 drives the first suction cup 34 to transfer the packaging box 9 to the loading station 4A; when the packaging boxes 9 in the storage mechanism 20 are sucked, the left and right telescopic modules 32 drive the first suction cup 34 to another storage mechanism 20 to take the packaging box 9 in the other storage mechanism 20, and at the same time, the system issues a feeding prompt (for example, through an audible and visual alarm or a display screen), and the empty trough 21 is manually pulled out to add materials, thereby avoiding the equipment from stopping during feeding.

[0046] like Figure 1 , Figures 3 to 5 and Fig. 9 As shown, as an embodiment, the packaging box feeding and folding mechanism also includes a detection mechanism 81, a control module 82 and an alarm module 83. The detection mechanism 81 is arranged at the loading station 4A and is connected to the base 1. The detection mechanism 81 is used to scan the material information on the packaging box 9; the control module 82 is respectively connected to the detection mechanism 81 and the alarm module 83. The control module 82 is used to compare the material information obtained by the detection mechanism 81 with the preset material information, and when the two are inconsistent, control the alarm module 83 to send out corresponding alarm information, and control the equipment to shut down (when the two are consistent, no alarm and shutdown action will be performed).

[0047] Specifically, in the actual production process, sometimes there will be a situation of mixed incoming materials, that is, the currently produced packaging box 9 is mixed with other types of packaging boxes 9 (other packaging boxes 9 have the same size but different types), and the prior art does not detect whether the type of packaging box 9 is correct, which leads to the problem of using the wrong material. In this embodiment, by setting a detection mechanism 81, the detection mechanism 81 is used to scan the material information on the packaging box 9. When the material information obtained by the detection mechanism 81 is inconsistent with the preset material information, the control module 82 controls the alarm module 83 to issue a corresponding alarm message and control the equipment to stop, thereby avoiding the problem of using the wrong material. In this embodiment, the detection mechanism 81 includes but is not limited to a code scanning device, a CCD camera, etc.; the material information on the packaging box 9 includes but is not limited to image information or text information such as a barcode 92 and a two-dimensional code, etc., and the material information can be set on the surface of the packaging box 9 by pasting or engraving (the material information is specifically set on the surface of the upper side plate 9A of the packaging box 9); the control module 82 can be specifically a PLC controller, etc.; the alarm module 83 can be specifically an audible and visual alarm, a display screen, etc. In this embodiment, the detection mechanism 81 is located above the loading station 4A, and the detection mechanism 81 is fixed to the base 1 through a support frame 811 .

The support plate 42 is fixedly connected to the base 1, and the support plate 42 extends along the left-right direction X. The support plate 42 is used to carry the packaging box 9 (that is, the packaging box 9 is placed on the support plate 42); the guard plate assembly 45 is used to abut against the packaging box 9 (specifically, the left side plate 9C and / or the right side plate 9D of the packaging box 9); the folded cover 41 is located on one side of the guard plate assembly 45 along the front-to-back direction Y; The horizontal driving device 43 and the first up-and-down driving device 44 are both located below the support plate 42; the first up-and-down driving device 44 is connected to the guard plate assembly 45 and the fold-down cover 41 at the same time, and the first up-and-down driving device 44 is used to drive the guard plate assembly 45 and the fold-down cover 41 to move up and down synchronously, so that the guard plate assembly 45 and the fold-down cover 41 can be simultaneously exposed upward to the support plate 42 or simultaneously retracted downward to the support plate 42, so that the guard plate assembly 45 can abut against the packaging box 9, and the fold-down cover 41 can fold the lower cover 911 of the packaging box 9 upward; The horizontal driving device 43 is connected to the first up-and-down driving device 44. The horizontal driving device 43 can be fixed to the base 1 or the support plate 42. The horizontal driving device 43 is used to drive the first up-and-down driving device 44 to move along the left-right direction X, thereby driving the guard plate assembly 45 and the folded cover 41 to move along the left-right direction X, and then the guard plate assembly 45 can drive the packaging box 9 to move along the left-right direction X and switch positions between various stations, thereby realizing the transplanting function of the transplanting mechanism 4. In this embodiment, the horizontal driving device 43 and the first up-and-down driving device 44 are both cylinders.

[0049] like Figure 1 and Figures 3 to 5 As shown, as an embodiment, the number of the guard plate assembly 45 is multiple, and the multiple guard plate assemblies 45 are arranged in sequence along the left-right direction X. Each guard plate assembly 45 includes at least one group of left guard plate 451 and right guard plate 452, and the left guard plate 451 and the right guard plate 452 are arranged at intervals from left to right. The left guard plate 451 and the right guard plate 452 are respectively used to abut against the left side plate 9C and the right side plate 9D of the packaging box 9, that is, the packaging box 9 is located between the left guard plate 451 and the right guard plate 452; when the horizontal driving device 43 drives the guard plate assembly 45 to move along the left-right direction X, the packaging box 9 can drive the packaging box 9 to move along the left-right direction X under the limit of the left guard plate 451 and the right guard plate 452. Multiple guard plate assemblies 45 are all connected to the first up and down driving device 44. The multiple guard plate assemblies 45 correspond to different workstation settings respectively. The horizontal driving device 43 can drive each guard plate assembly 45 to switch positions between two adjacent workstations, and drive the folded cover 41 to switch positions between the box opening station 4B and the box folding station 4C.

[0050] Specifically, in the present embodiment, the transplanting mechanism 4 is further provided with a lining installation station 4D, which is located on the side of the box folding station 4C away from the box folding station 4B. At the lining installation station 4D, a lining installation device (not shown) can load the lining into the packaging box 9 through the front opening of the packaging box 9 (the present invention does not involve the lining installation step, so it will not be introduced in detail). In this embodiment, there are three support plates 42, and the three support plates 42 are arranged at intervals along the front-to-back direction Y; each guard plate assembly 45 includes two groups of left guard plates 451 and right guard plates 452, one group of left guard plates 451 and right guard plates 452 is located between the first support plate 42 and the second support plate 42, and the other group of left guard plates 451 and right guard plates 452 is located between the second support plate 42 and the third support plate 42; when the first up and down drive device 44 drives the guard plate assembly 45 to move upward, the packaging box 9 is located between the two groups of left guard plates 451 and right guard plates 452, so that the packaging box 9 can move more stably under the limitation of the two groups of left guard plates 451 and right guard plates 452. In this embodiment, the number of the guard plate assemblies 45 is three, and the three guard plate assemblies 45 can be synchronously moved left and right under the drive of the horizontal driving device 43, so that the packaging boxes 9 at the feeding station 4A, the box opening station 4B and the box folding station 4C are synchronously moved to the left by one station respectively, so as to realize continuous operation. Specifically, in the direction from the feeding station 4A to the box opening station 4B, the three guard plate assemblies 45 are respectively the first guard plate assembly 45, the second guard plate assembly 45 and the third guard plate assembly 45, and the folded cover 41 is located on one side of the second guard plate assembly 45 along the front-back direction Y (in other embodiments, when the transplanting mechanism 4 is not provided with the lining station 4D, only the first guard plate assembly 45 and the second guard plate assembly 45 can be provided).During operation, after the loading mechanism 3 transfers the packaging box 9 from the feeding mechanism 2 to the loading station 4A, the horizontal drive device 43 drives the three guard plate assemblies 45 to move to the right synchronously (at this time, the guard plate assembly 45 and the folded cover 41 are both retracted downward to under the support plate 42), so that the first guard plate assembly 45 moves to the loading station 4A, the folded cover 41 and the second guard plate assembly 45 move to the box opening station 4B, and the third guard plate assembly 45 moves to the box folding station 4C, and then the first up and down drive device 44 drives the three guard plate assemblies 45 and the folded cover 41 upward to expose above the support plate 42. At this time, the three guard plate assemblies 45 are respectively It is abutted against the three packaging boxes 9 at the loading station 4A, the box opening station 4B and the box folding station 4C, and at the same time, the cover 41 is folded down to fold the lower cover 911 of the packaging box 9 at the box opening station 4B upwards, and then the horizontal driving device 43 drives the three guard plate assemblies 45 to move one station to the left synchronously, so that the packaging boxes 9 at the loading station 4A, the box opening station 4B and the box folding station 4C are respectively moved one station to the left synchronously, and the folded cover 41 will always hold the lower cover 911 of the packaging box 9 and move from the box opening station 4B to the box folding station 4C; after the folding of the rear cover 91 of the packaging box 9 is completed, the transplanting mechanism 4 repeats the above operation.

[0051] like Figure 1 and Figure 7 As shown, as an embodiment, the box opening mechanism 6 is located on one side of the transplanting mechanism 4 along the front-to-back direction Y. The box opening mechanism 6 includes a horizontal driving mechanism 61, a flip driving mechanism 62, a flipping member 63 and a fixed pressing member 64. The horizontal driving mechanism 61 is fixed to the base 1 through a third leg 66, and the flipping member 63 is located on one side of the fixed pressing member 64 along the left-right direction X; the flip driving mechanism 62 and the fixed pressing member 64 are both connected to the horizontal driving mechanism 61, and the flipping member 63 is connected to the flip driving mechanism 62; the horizontal driving mechanism 61 is used to drive the flipping member 63 and the fixed pressing member 64 to move along the front-to-back direction Y, so that the flipping member 63 and the fixed pressing member 64 can extend from the front opening of the packaging box 9 into the packaging box 9 or be pulled out of the packaging box 9; the fixed pressing member 64 is used to press the lower side plate 9B of the packaging box 9; the flip driving mechanism 62 is used to drive the flipping member 63 to rotate, thereby driving the left side plate 9C and the right side plate 9D of the packaging box 9 to rotate, thereby opening and flipping the packaging box 9. In this embodiment, the horizontal driving mechanism 61 can be a linear guide module, a motor belt assembly, etc., and the flip driving mechanism 62 can be a rotary cylinder, a rotary motor, etc. The flip member 63 and the fixed pressing member 64 are both plate-shaped structures, and the flip member 63 and the fixed pressing member 64 are both on the same plane (or approximately on the same plane).

[0052] The box opening mechanism 6 further includes a second up-down driving device 65, which is connected to the horizontal driving mechanism 61, and the fixed pressing member 64 is connected to the second up-down driving device 65 (i.e., the fixed pressing member 64 is connected to the horizontal driving mechanism 61 through the second up-down driving device 65); the second up-down driving device 65 is used to drive the fixed pressing member 64 to move up and down, so that the fixed pressing member 64 is in contact with or separated from the lower side plate 9B of the packaging box 9, thereby preventing the fixed pressing member 64 from causing the position of the packaging box 9 to shift when being drawn out of the packaging box 9. In this embodiment, the second up-down driving device 65 can be a cylinder or the like.

[0053] like Figures 3 to 6 As shown, the pressing mechanism 52 includes a first telescopic module 521 and a pressing plate 522, the pressing plate 522 is used to press the flipped packaging box 9 from top to bottom; the first telescopic module 521 is connected to the pressing plate 522, and the first telescopic module 521 is used to drive the pressing plate 522 to telescopically move up and down, so that the pressing plate 522 can press the packaging box 9. The first telescopic module 521 can be specifically a cylinder.

[0054] like Figures 3 to 6As shown, the pressure protection mechanism 5 also includes an opening mechanism 54, and the opening mechanism 54 includes a third up-and-down driving device 541 and a second suction cup 542, and the second suction cup 542 is arranged on the third up-and-down driving device 541; the second suction cup 542 is used to adsorb the upper side plate 9A of the packaging box 9, and the third up-and-down driving device 541 is used to drive the second suction cup 542 to move up and down, so that the second suction cup 542 can pull the upper side plate 9A of the packaging box 9 upwards, thereby expanding the opening of the packaging box 9 close to the side of the opening mechanism 6 (that is, the front opening of the packaging box 9), so as to facilitate the flipping member 63 and the fixed pressure member 64 to extend into the packaging box 9. In this embodiment, the third up-and-down driving device 541 includes a first cylinder 5411 and a second cylinder 5412, the second suction cup 542 is arranged on the second cylinder 5412, and the first cylinder 5411 is connected to the second cylinder 5412; wherein the second cylinder 5412 is used to directly drive the second suction cup 542 to move up and down to expand the front opening of the packaging box 9; the first cylinder 5411 is used to drive the second cylinder 5412 and the second suction cup 542 to move up and down to avoid the interference between the flip member 63 and the second cylinder 5412 and the second suction cup 542 during the rotation process (that is, the second cylinder 5412 is used to realize the opening function of the opening mechanism 54). Yes, the first cylinder 5411 is used to avoid interference between the opening mechanism 54 and the flip member 63. Since the cylinder generally has only one stroke when extending and retracting up and down, in order to avoid interference between the opening mechanism 54 and the flip member 63, if only one cylinder is provided, the upward stroke of the cylinder needs to be set larger, so that the cylinder and the second suction cup 542 can pull the upper side plate 9A of the packaging box 9 upward by a greater distance; and in actual use, it is only necessary to pull the upper side plate 9A of the packaging box 9 upward by a short distance to expand the front opening of the packaging box 9 a little bit, and at this time the flip member 63 and the fixed pressing member 64 can extend into the packaging box 9).

[0055] Specifically, in the present embodiment, after the packaging box 9 is moved from the loading station 4A to the box opening station 4B, the first cylinder 5411 and the second cylinder 5412 in the opening mechanism 54 are simultaneously actuated to move the second suction cup 542 downward, and then the second suction cup 542 sucks the upper side plate 9A of the packaging box 9; the second cylinder 5412 is actuated to drive the second suction cup 542 to move upward and pull the upper side plate 9A of the packaging box 9 upward, thereby expanding the front opening of the packaging box 9 (since the packaging box 9 is flat, its front opening is small, which makes it inconvenient for the flipping member 63 and the fixed pressing member 64 to extend into the packaging box 9. When the second suction cup 542 pulls the upper side plate 9A upward, the front opening of the packaging box 9 will expand under the action of its own gravity; of course, a suction cup can also be provided at the box opening station 4B of the transplanting mechanism 4 to suck the lower side plate 9B of the packaging box 9 for a better opening). Then the horizontal driving mechanism 61 in the box opening mechanism 6 is actuated, driving the flipping member 63 and the fixed pressing member 64 to extend from the front opening of the packaging box 9 into the packaging box 9, at which time the fixed pressing member 64 presses against the lower side plate 9B of the packaging box 9; then the first cylinder 5411 in the opening mechanism 54 is actuated, causing the second cylinder 5412 and the second suction cup 542 to move upward and retract (at which time the second suction cup 542 releases the upper side plate 9A of the packaging box 9) to avoid interference between the opening mechanism 54 and the flipping member 63. Fig.10 , and then the flip driving mechanism 62 in the box opening mechanism 6 is actuated to drive the flip member 63 to rotate and drive the left side plate 9C and the right side plate 9D of the packaging box 9 to rotate (in the present embodiment, when the flip member 63 rotates, the flip member 63 will abut against the right side plate 9D and directly drive the right side plate 9D to rotate. At the same time, since the fixed pressing member 64 abuts against the lower side plate 9B of the packaging box 9, the right side plate 9D will drive the left side plate 9C to rotate together when rotating), thereby opening the packaging box 9 and flipping it 180° (i.e., by Fig.10 Then the first telescopic module 521 in the pressing mechanism 52 drives the pressing plate 522 to move downward, so that the pressing plate 522 presses the flipped packaging box 9 from top to bottom to prevent the packaging box 9 from rebounding after opening; then the first telescopic module 521 drives the pressing plate 522 to move upward and retract, and the flip driving mechanism 62 drives the flip member 63 to rotate in the opposite direction and reset. At this time, the packaging box 9 can bounce up under the elastic force of its own material and form a hollow cube shape (that is, the packaging box 9 is formed by the flipping member 63). Fig.10The state 2 in the box 9 is changed to the state 3). Then the first up-down driving device 44 in the transplanting mechanism 4 is actuated to drive the guard plate assembly 45 and the folded cover 41 to move upward and expose above the support plate 42. At this time, the folded cover 41 folds the lower cover 911 of the packaging box 9 upward with the cooperation of the fixed pressing member 64. Then the second up-down driving device 65 in the box opening mechanism 6 drives the fixed pressing member 64 to move upward a short distance, so that the fixed pressing member 64 is separated from the lower side plate 9B of the packaging box 9 (to prevent the fixed pressing member 64 from driving the packaging box 9 to move when it is pulled out of the packaging box 9, causing the position of the packaging box 9 to shift). Then the horizontal driving mechanism 61 in the box opening mechanism 6 is actuated to drive the flipping member 63 and the fixed pressing member 64 to be pulled out of the packaging box 9 from the front opening of the packaging box 9. Then the horizontal driving device 43 in the transplanting mechanism 4 is activated to drive the guard plate assembly 45 to move the packaging box 9 from the box opening station 4B to the box folding station 4C (Note: since the folded cover 41 will move from the box opening station 4B to the box folding station 4C, the lower cover 911 of the packaging box 9 will always be in an upward folded state at this time).

[0056] Since the folded cover 41 in this embodiment is arranged on the transplanting mechanism 4, the folded cover 41 can move up and down with the transplanting mechanism 4 to fold the lower cover 911 of the packaging box 9, thereby eliminating the driving device that separately drives the folded cover 41 to move up and down, thereby saving costs and helping to reduce the space occupied by the equipment.

[0057] like Figures 1 to 6 As shown, as an embodiment, the pressure protection mechanism 5 also includes a fixing mechanism 55, and the fixing mechanism 55 is arranged corresponding to the folding box station 4C. The fixing mechanism 55 includes a fourth up and down driving device 551, a third suction cup 552 and a pressure protection assembly 553, and the third suction cup 552 and the pressure protection assembly 553 are both connected to the fourth up and down driving device 551, and the fourth up and down driving device 551 is used to drive the third suction cup 552 and the pressure protection assembly 553 to move up and down. The transplanting mechanism 4 is provided with a fourth suction cup 46, and the fourth suction cup 46 is arranged at the folding box station 4C. The third suction cup 552 is used to absorb the upper side plate 9A of the packaging box 9, the pressure protection assembly 553 is used to abut against the left side plate 9C and the right side plate 9D of the packaging box 9, and the fourth suction cup 46 is used to absorb the lower side plate 9B of the packaging box 9, and then the four side plates of the packaging box 9 are fixed, so as to realize the fixing and limiting of the packaging box 9 when the rear cover of the packaging box 9 is folded, avoid the position of the packaging box 9 from being offset, and improve the accuracy and efficiency of the rear cover of the packaging box 9.

[0058] Specifically, in this embodiment, the fourth up-and-down driving device 551 can be a cylinder, etc. The pressure protection assembly 553 includes a first pressure protection portion 5531 and a second pressure protection portion 5532 that are spaced apart from each other. The first pressure protection portion 5531 and the second pressure protection portion 5532 are used to abut against the left side plate 9C and the right side plate 9D of the packaging box 9, respectively.

[0059] like Figure 1 and Figure 6 As shown, as an embodiment, the folding cover mechanism 53 includes a second telescopic module 531 and a folding cover member 532. The folding cover member 532 is connected to the second telescopic module 531. The second telescopic module 531 is used to drive the folding cover member 532 to move up and down, so that the folding cover member 532 can fold the upper cover 912 of the packaging box 9 downward. The second telescopic module 531 can be specifically a cylinder or the like.

[0060] like Figures 1 to 6 As shown, as an embodiment, the pressure protection mechanism 5 also includes a mounting plate 51, the mounting plate 51 is located above the transplanting mechanism 4, the mounting plate 51 is fixedly connected to the base 1 through the second leg 511, and the pressing mechanism 52, the folding cover mechanism 53, the opening mechanism 54 and the fixing mechanism 55 are all connected to the mounting plate 51. Specifically, the first telescopic module 521 in the pressing mechanism 52, the second telescopic module 531 in the folding cover mechanism 53, the third up-and-down driving device 541 (specifically the first cylinder 5411) in the opening mechanism 54 and the fourth up-and-down driving device 551 in the fixing mechanism 55 are all fixedly connected to the mounting plate 51.

[0061] like Figure 1 and Figure 8 As shown, as an embodiment, the folding left cover mechanism 71 includes a first telescopic driving device 711, a folding left cover member 712 and a first bracket 713, wherein the first telescopic driving device 711 is fixedly connected to the base 1 through the first bracket 713; the folding left cover member 712 is connected to the first telescopic driving device 711, and the first telescopic driving device 711 is used to drive the folding left cover member 712 to telescopically move along a first direction (not numbered in the figure), so that the folding left cover member 712 can fold the left cover 913 of the packaging box 9 to the right (when the first telescopic driving device 711 drives the folding left cover member 712 to move toward the left cover 913, the folding left cover member 712 can abut against the left cover 913 and fold the left cover 913 to the right). Among them, the angle between the first direction and the right direction of the left-right direction X is greater than 0° and less than 90°. The first telescopic driving device 711 can specifically be a cylinder or the like.

[0062] The right cover folding mechanism 72 includes a second telescopic drive device 721, a right cover folding member 722 and a second bracket 723. The second telescopic drive device 721 is fixedly connected to the base 1 through the second bracket 723; the right cover folding member 722 is connected to the second telescopic drive device 721, and the second telescopic drive device 721 is used to drive the right cover folding member 722 to telescopically move along the second direction (not numbered in the figure), so that the right cover folding member 722 can fold the right cover 914 of the packaging box 9 to the left (when the second telescopic drive device 721 drives the right cover folding member 722 to move toward the right cover 914, the right cover folding member 722 can abut against the right cover 914 and fold the right cover 914 to the left). Among them, the angle between the second direction and the left direction of the left-right direction X is greater than 0° and less than 90°. The second telescopic drive device 721 can specifically be a cylinder or the like.

[0063] The cover pressing mechanism 73 includes a third telescopic driving device 731, a cover pressing member 732 and a third bracket 733. The third telescopic driving device 731 is fixedly connected to the base 1 through the third bracket 733; the cover pressing member 732 is connected to the third telescopic driving device 731, and the third telescopic driving device 731 is used to drive the cover pressing member 732 to move telescopically along a third direction (not numbered in the figure), so that the cover pressing member 732 can press the upper cover 912 of the packaging box 9 to the lower cover 911, the left cover 913 and the left cover 914. The upper cover 912 of the packaging box 9 is folded downward by the folding cover mechanism 53, but the folding cover mechanism 53 cannot fold the upper cover 912 between the lower cover 911, the left cover 913 and the right cover 914. When the third telescopic drive device 731 drives the pressing cover member 732 to move toward the upper cover 912, the pressing cover member 732 can abut against the end of the upper cover 912 and fold the end of the upper cover 912 inward to between the lower cover 911, the left cover 913 and the right cover 914. Among them, the angle between the third direction and the left-right direction X is 90°, that is, the third direction is parallel to the front-back direction Y. The third telescopic drive device 731 can specifically be a cylinder or the like.

[0064] As an implementation method, the working steps of the packaging box feeding and folding mechanism are as follows: (1) Manually load two stacks of flat packaging boxes 9 into the two storage mechanisms 20 of the feeding mechanism 2, and scan the barcode 92 on the packaging box 9 into the device (that is, enter the preset material information into the control module 82) for subsequent detection and comparison (specifically, a scanner can be set to scan the barcode 92).

[0065] (2) The equipment is started, and the feeding mechanism 3 first takes materials from one of the storage mechanisms 20, and places the sucked packaging boxes 9 at the feeding station 4A of the transplanting mechanism 4. When the packaging boxes 9 in the storage mechanism 20 are sucked out, the feeding mechanism 3 takes materials from another storage mechanism 20, and the system issues a reminder to add materials (for example, by sound and light alarm or display on the display screen), and then the empty material trough 21 is manually pulled out to add materials, thereby avoiding the equipment from stopping during the addition of materials.

[0066] (3) After the packaging box 9 is transferred to the loading station 4A, the detection mechanism 81 automatically scans the barcode 92 on the packaging box 9, and the control module 82 compares the barcode 92 obtained by the detection mechanism 81 with the pre-entered barcode 92. When the two are inconsistent, the control module 82 controls the alarm module 83 to issue a corresponding alarm message and control the equipment to stop; when the two are consistent, it is determined to be OK and continue to the next process.

[0067] (4) The transfer mechanism 4 moves the packaging box 9 at the loading station 4A to the box opening station 4B (at the same time, the transfer mechanism 4 moves the packaging box 9 at the box opening station 4B to the box folding station 4C, and moves the packaging box 9 at the box folding station 4C to the lining station 4D).

[0068] (5) After the packaging box 9 is transferred to the box opening station 4B, the first cylinder 5411 and the second cylinder 5412 in the opening mechanism 54 are simultaneously actuated to move the second suction cup 542 downward, and then the second suction cup 542 sucks the upper side plate 9A of the packaging box 9; the second cylinder 5412 is actuated to drive the second suction cup 542 to move upward and pull the upper side plate 9A of the packaging box 9 upward, thereby expanding the front opening of the packaging box 9 (to facilitate the turning member 63 and the fixed pressing member 64 to extend into the packaging box 9).

[0069] (6) The horizontal driving mechanism 61 in the box opening mechanism 6 is actuated to drive the flipping member 63 and the fixed pressing member 64 to extend from the front opening of the packaging box 9 into the packaging box 9. At this time, the fixed pressing member 64 presses against the lower side plate 9B of the packaging box 9. Then, the first cylinder 5411 in the opening mechanism 54 is actuated to cause the second cylinder 5412 and the second suction cup 542 to move upward and retract (at this time, the second suction cup 542 releases the upper side plate 9A of the packaging box 9) to prevent the opening mechanism 54 from interfering with the flipping member 63 during the rotation process.

[0070] (7) The flipping driving mechanism 62 in the box opening mechanism 6 is actuated to drive the flipping member 63 to rotate and drive the left side plate 9C and the right side plate 9D of the packaging box 9 to rotate (in the present embodiment, when the flipping member 63 rotates, the flipping member 63 will abut against the right side plate 9D and directly drive the right side plate 9D to rotate. At the same time, since the fixed pressing member 64 abuts against the lower side plate 9B of the packaging box 9, the right side plate 9D will drive the left side plate 9C to rotate together through the upper side plate 9A when rotating), thereby opening the packaging box 9 and flipping it 180° (i.e., the packaging box 9 is opened and flipped 180° by Fig.10 State 1 in the process changes to state 2).

[0071] Then, the first telescopic module 521 in the pressing mechanism 52 drives the pressing plate 522 to move downward, so that the pressing plate 522 presses the flipped packaging box 9 from top to bottom to shape the packaging box 9 and prevent the packaging box 9 from rebounding after opening the box; then, the first telescopic module 521 drives the pressing plate 522 to move upward and retract, and the flip driving mechanism 62 drives the flip member 63 to rotate in the opposite direction and reset. At this time, the packaging box 9 can bounce up under the elastic force of its own material and form a hollow cube shape (i.e., the packaging box 9 is formed by the hollow cube shape). Fig.10 Note: During the box opening process, the guard plate assembly 45 and the fold-down cover 41 are located below the support plate 42 to avoid the packaging box 9 from abutting and interfering with the guard plate assembly 45 and the fold-down cover 41 during the box opening process.

[0072] (8) The first up-down driving device 44 in the transplanting mechanism 4 is actuated, driving the guard plate assembly 45 and the folded cover member 41 to move upward and expose above the support plate 42. At this time, the folded cover member 41, in cooperation with the fixed pressing member 64, folds the lower cover 911 of the packaging box 9 upward. Then the second up-down driving device 65 in the box opening mechanism 6 drives the fixed pressing member 64 to move upward a short distance, so that the fixed pressing member 64 is separated from the lower side plate 9B of the packaging box 9 (to prevent the fixed pressing member 64 from driving the packaging box 9 to move when it is pulled out of the packaging box 9, causing the position of the packaging box 9 to shift).

At the same time, the third suction cup 552 sucks the upper side plate 9A of the packaging box 9, thereby fixing the four side plates of the packaging box 9 to prevent the position of the packaging box 9 from shifting.

[0074] (10) The left cover folding mechanism 71 and the right cover folding mechanism 72 are simultaneously operated to fold the left cover 913 of the packaging box 9 to the right and the right cover 914 of the packaging box 9 to the left, respectively, so that the left cover 913 and the right cover 914 are placed on the lower cover 911; then the second telescopic module 531 in the upper cover folding mechanism 53 is operated to fold the upper cover 912 of the packaging box 9 downward, so that the left and right sides of the upper cover 912 are placed on the left cover 913 and the right cover 914 respectively. Then the fourth suction cup 46 stops working, and the first up-and-down driving device 44 in the transfer mechanism 4 is operated to drive the guard plate assembly 45 and the folded-down cover member 41 to move downward and retract, so that the folded-down cover member 41 is pulled out downward, and then the upper cover pressing mechanism 73 is operated to press and fold the end of the upper cover 912 inward to between the lower cover 911, the left cover 913 and the right cover 914, thereby completing the folding of the lower cover 91.
