[0030] like Figures 1 to 3 As shown, the first embodiment of the present application provides a packaging box 10 molding device for molding the packaging box 10, the packaging box 10 includes a side portion 20 and a bottom 30 connected to one end of the side portion 20, and the molding device includes: a silo 100, a material picking mechanism 200 and a molding mechanism 300; the silo 100 includes a accommodating cavity 110 for accommodating the packaging box 10 and an opening 120 connected to the accommodating cavity 110; the material picking mechanism 200 includes a grasping portion 210 for grasping the packaging box 10 through the opening 120; the molding mechanism 300 is arranged on a side of the opening 120 away from the accommodating cavity 110, and the molding mechanism 300 includes a plurality of movable arms, and the arms are used to fold and mold the bottom 30 of the packaging box 10.

[0031] The packaging box 10 includes a side portion 20 and a bent edge of a bottom 30 connected to one end of the side portion 20, and the bent edge is bent and overlapped to form the bottom 30 of the packaging box 10. In this embodiment, the packaging box 10 is arranged in the accommodating cavity 110, and the gripping portion 210 takes the packaging box 10 out of the accommodating cavity 110 through the opening 120 to the side of the opening 120 away from the accommodating cavity 110. The forming mechanism 300 includes a plurality of movable arms, and the arms are used to abut against the bent edges to overlap the bent edges to form the bottom 30 of the packaging box 10. The bottom 30 of the packaging box 10 is formed by a plurality of arms, which improves the forming efficiency of the packaging box 10 compared to the manual forming of the packaging box 10.

[0032] like Figure 2 and Figure 4 As shown, in some optional embodiments, the packaging box 10 molding device also includes an opening assembly 400, which is arranged between the opening 120 and the molding mechanism 300, and the opening assembly 400 includes a first guide portion 410 and a second guide portion 420 arranged relatively to each other; in the direction away from the opening 120, the distance between at least part of the first guide portion 410 and at least part of the second guide portion 420 gradually decreases.

[0033] In these optional embodiments, in the foldable storage and accommodating cavity 110 of the packaging box 10, the packaging box 10 may include four side portions 20 connected end to end in sequence, wherein the angle between the adjacent first side portion and the second side portion facing the opening 120 is 180 degrees, and the angle between the two adjacent side portions 20 away from the opening 120 is 180 degrees. After the grasping portion 210 grasps the first side portion, the grasping portion 210 drives the packaging box 10 to pass between the first guide portion 410 and the second guide portion 420 in a direction away from the opening 120, and the spacing between at least part of the first guide portion 410 and at least part of the second guide portion 420 gradually decreases, and one of the first guide portion 410 and the second guide portion 420 pushes the second side portion to reduce the angle between the second side portion and the first side portion from 180 degrees to 90 degrees. In the process, the two adjacent side walls away from the opening 120 are also reduced from 180 degrees to 90 degrees, and the packaging box 10 changes from a folded state to a three-dimensional state. By providing the forming mechanism 300 , the packaging box 10 can be stored in the accommodating cavity 110 in a folded state, so that the accommodating cavity 110 can accommodate more packaging boxes 10 .

[0034] Optionally, the first guide portion 410 and the second guide portion 420 are arranged opposite to each other along the first direction X, and the minimum spacing between the first guide portion 410 and the second guide portion 420 can be equal to the dimension of the first side portion along the first direction X, or the minimum spacing between the first guide portion 410 and the second guide portion 420 can be greater than the dimension of the first side portion along the first direction X and less than the sum of the dimensions of the first side portion and the second side portion along the first direction X.

[0035] like Figure 2 and Figure 4 As shown, in some optional embodiments, at least one of the first guide portion 410 and the second guide portion 420 is movably disposed in a direction approaching or moving away from the other.

[0036] In these optional embodiments, at least one of the first guide portion 410 and the second guide portion 420 is slidably connected to a light rod or a lead screw, or may be other forms of components capable of moving the guide portion, so that at least one of the first guide portion 410 and the second guide portion 420 can move in a direction closer to or away from the other to accommodate packaging boxes 10 of different specifications.

[0037] like Figure 4 As shown, in some optional embodiments, at least a portion of the first guide portion 410 and at least a portion of the second guide portion 420 are arc-shaped, and the arc-shaped first guide portion 410 and the arc-shaped second guide portion 420 both include relatively arranged convex side surfaces and concave side surfaces, and the convex side surfaces of the first guide portion 410 and the second guide portion 420 are arranged facing each other so that the distance between the first guide portion 410 and the second guide portion 420 gradually decreases in the direction away from the opening 120.

[0038] In these optional embodiments, at least part of the first guide portion 410 and at least part of the second guide portion 420 are arc-shaped structures, the convex side surfaces of the first guide portion 410 and the second guide portion 420 are arranged facing each other, and the spacing between the first guide portion 410 of the arc-shaped part and the second guide portion 420 of the arc-shaped part transitions from large to small in an arc shape, so that the packaging box 10 can be smoother when abutting against the guide portion. In addition, since the material of the packaging box 10 is relatively soft, the side portion 20 of the packaging box 10 is a plane, when the convex side surface abuts against the side portion 20 of the plane structure, the first guide portion 410 and the second guide portion 420 of the arc-shaped structure can reduce the probability of scratching the packaging box 10, which is conducive to increasing the product yield.

[0039] like Figure 4 As shown, in some optional embodiments, the box opening assembly 400 also includes a fixing portion 430, and an avoidance groove 440 is provided on the first guide portion 410, the avoidance groove 440 is provided on the side of the first guide portion 410 away from the opening 120, and the fixing portion 430 is provided in the avoidance groove 440, and the fixing portion 430 is movably provided in a direction close to or away from the second guide portion 420.

[0040] In these optional embodiments, the avoidance groove 440 is arranged on the side of the first guide portion 410 away from the opening 120. The purpose is to set the avoidance groove 440 at the position after the four side portions 20 of the packaging box 10 are formed. After the side portions 20 of the packaging box 10 are formed, the bottom 30 forming process is carried out. The fixing portion 430 is movable in a direction close to the second guide portion 420, and the packaging box 10 is pressed against the convex side surface of the second guide portion 420 to fix the packaging box 10 to prevent the packaging box 10 from falling off from the gripping portion 210 when the bottom 30 is formed.

[0041] like Figure 4 As shown, in some optional embodiments, the first guide portion 410 and the second guide portion 420 include a first section 450 and a second section 460 along a direction away from the opening 120, and the spacing between the first guide portion 410 and the second guide portion 420 in the first section 450 gradually decreases along a direction away from the opening 120; the spacing between the first guide portion 410 and the second guide portion 420 in the second section 460 along a direction away from the opening 120 is equal, and the avoidance groove 440 is arranged in the second section 460.

[0042] In these optional embodiments, when the packaging box 10 passes through the first section 450, the spacing between the first guide portion 410 and the second guide portion 420 in the first section 450 is gradually reduced in the direction away from the opening 120 to shape the side portion 20 of the packaging box 10. When the packaging box 10 enters the second section 460, the avoidance groove 440 is provided in the second section 460, and the fixing portion 430 is located in the avoidance groove 440 and can move and fix the packaging box 10 in the direction close to the second guide portion 420. Optionally, a first lead screw 480 is connected to the side of the fixing portion 430 away from the second guide portion 420, and the first lead screw 480 drives the fixing portion 430 to move in the direction close to or away from the second guide portion 420.

[0043] It can be understood that the first section 450 can be an arc-shaped structure to gradually reduce the distance between the first guide portion 410 and the second guide portion 420, and the second section 460 is a planar structure. Since the side portion 20 of the packaging box 10 is a plane, when the fixing portion 430 pushes the packaging box 10 to the second guide portion 420 of the planar structure, the contact area between the second guide portion 420 and the side portion 20 of the packaging box 10 is larger, which is conducive to increasing static friction, thereby fixing the packaging box 10 more firmly.

[0044] like Figure 2 and Figure 4 As shown, in some optional embodiments, a first channel 470 is formed between the first guide portion 410 and the second guide portion 420 , and the first channel 470 is configured so that the grasping portion 210 grasps the packaging box 10 through the opening 120 and passes through the first channel 470 .

[0045] In these optional embodiments, a spacing is left between the first guide portion 410 and the second guide portion 420 to form a first channel 470, and the first channel 470 corresponds to the position of the opening 120. The grasping portion 210 moves in a direction close to the opening 120 through the first channel 470. After the grasping portion 210 grasps the packaging box 10, it moves in a direction away from the opening 120 through the first channel 470. The grasping portion 210 and the packaging box 10 both pass through the first channel 470. The movement of the grasping portion 210 in the first channel 470 between the guide portions is conducive to making the components of the packaging box 10 molding equipment more compact.

[0046] Optional, such as Figure 1 As shown, the material picking mechanism 200 includes a third driving motor 220, which is connected to a swing arm 240 via a connecting rod 230. The end of the swing arm 240 is connected to the grabbing part 210. The third driving motor 220 rotates through the connecting rod 230 to drive the swing arm 240 to swing so that the grabbing part 210 is close to or away from the opening 120.

[0047] like Figure 1 As shown, in some optional embodiments, the gripping portion 210 includes a suction cup, and the suction cup is used to suck the side portion 20 of the packaging box 10.

[0048] In these optional embodiments, the suction cup can be connected to a negative pressure mechanism, which is connected to the suction cup and absorbs the air between the suction cup and the side portion 20 to form negative pressure adsorption, so that the suction cup absorbs the side portion 20 of the packaging box 10, and a vacuum is formed between the suction cup and the side portion 20 through the negative pressure mechanism, so that the suction cup grasps the packaging box 10 more firmly, reducing the probability of the packaging box 10 falling off the suction cup.

[0049] Optionally, the gripping portion 210 may also include an adhesive portion to adhere to the side portion 20 of the packaging box 10 , or the gripping portion 210 may also include other structures capable of gripping the side portion 20 of the packaging box 10 .

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, in some optional embodiments, the arm includes two first arm portions 310 arranged relatively to each other along a first direction X, and a second arm portion 320 and a third arm portion 330 arranged relatively to each other along a second direction Y, and the first arm portion 310, the second arm portion 320 and the third arm portion 330 are configured to be movable in a direction close to or away from the bottom 30 of the packaging box 10 to fold and form the bottom 30 of the packaging box 10; the first direction X and the second direction Y intersect.

[0051] In these optional embodiments, the bottom 30 of the packaging box 10 is composed of four bending edges, including a first bending edge 31, a second bending edge 32, a third bending edge 33 and a fourth bending edge 34, wherein, before the bottom 30 of the packaging box 10 is formed, the first bending edge 31 and the fourth bending edge 34 are arranged relatively along the second direction Y, and the second bending edge 32 and the third bending edge 33 are arranged relatively along the first direction X. The first bending edge 31, the second bending edge 32, the third bending edge 33 and the fourth bending edge 34 are respectively connected to the four side portions 20 of the packaging box 10 and are coplanar with the side portions 20 of the packaging box 10 or the angle is greater than 90 degrees. It is understandable that before the bottom 30 of the packaging box 10 is formed, the four bending edges can be coplanar with the four side portions 20, and since the packaging box 10 is a soft material, the bending edge may be bent to a certain extent with the side portions 20 under gravity or external force.

[0052] The second arm 320 moves toward the first bent edge 31 to push the first bent edge 31 to the middle area surrounded by the four side portions 20, and then the two first arm portions 310 relatively arranged along the first direction X move toward the second bent edge 32 and the third bent edge 33 to push the second bent edge 32 and the third bent edge 33 to the middle area surrounded by the four side portions 20, so that the second bent edge 32 and the third bent edge 33 are buckled with the first bent edge 31, and finally the third arm portion 330 pushes the fourth bent edge 34 toward the fourth bent edge 34 to the middle area surrounded by the four side portions 20, so that the fourth bent edge 34 is buckled with the first bent edge 31, the second bent edge 32 and the third bent edge 33 to form the bottom 30 of the packaging box 10.

[0053] Optionally, the first arm 310 , the second arm 320 , and the third arm 330 are respectively provided with driving mechanisms to drive the first arm 310 , the second arm 320 , and the third arm 330 to move in a direction approaching or moving away from the packaging box 10 .

[0054] Optionally, the end of the first arm 310 facing away from the packaging box 10 is connected to the rack 311 through the gear 312, the second screw drives the rack 311 to move, and the rack 311 drives the gear 312 to rotate and drive the first arm 310 to rotate, so that the other end of the first arm 310 moves toward the bending edge.

[0055] Optionally, the packaging box 10 forming device also includes a second drive motor 340, which is connected to the main shaft 350 and drives the main shaft 350 to rotate. The main shaft 350 is rotatably connected to the fixed block 360, and the second arm 320 is sleeved on the main shaft 350. The second drive motor 340 drives the main shaft 350 to rotate, and the main shaft 350 drives the second arm 320 to rotate to push the first bending edge 31.

[0056] Optionally, the second arm 320 includes an execution end 321 and a transmission end 322, the main shaft 350 is located between the execution end 321 and the transmission end 322, and the execution end 321 is used to push the first bending edge 31. One end of the two opposite ends of the third arm 330 is rotatably connected to the fixed block 360, and the other end of the two opposite ends of the third arm 330 is used to push the fourth bending edge 34, and the middle between the two ends of the third arm 330 is connected to the transmission end 322 through a transmission rod 331. When the execution end 321 of the second arm 320 moves toward the packaging box 10, the transmission end 322 of the second arm 320 pulls the third arm 330 to move in a direction away from the packaging box 10 through the transmission rod 331. When the execution end 321 of the second arm 320 moves toward the direction away from the packaging box 10, the transmission end 322 of the second arm 320 pushes the third arm 330 to move in a direction close to the fourth bending edge 34 through the transmission rod 331 and pushes the bending edge.

[0057] Optionally, the first direction X and the second direction Y are arranged perpendicular to each other.

[0058] like Figure 2 As shown, in some optional embodiments, the gripping portion 210 is movably disposed along the second direction Y, and the silo 100 is movably disposed along the first direction X, and the first direction X and the second direction Y intersect.

[0059] In these optional embodiments, the silo 100 includes a accommodating cavity 110, which simultaneously accommodates two specifications of packaging boxes 10. The two specifications of packaging boxes 10 are grasped at different positions. The grasping portion 210 moves along the second direction Y close to the opening 120, so that the silo 100 moves along the first direction X, so that the grasping position of the grasping portion 210 can be adjusted to adapt to packaging boxes 10 of different specifications.

[0060] Optionally, the first direction X may be a horizontal direction, and the second direction Y may be a vertical direction perpendicular to the horizontal direction.

[0061] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application.
