[0035] First Embodiment

[0036] The molding device provided by the embodiments of the present application is used to prepare the buffer structure 100, and the buffer structure 100 is composed of Figure 1The cardboard structure 1000 shown is formed by bending. The cardboard structure 1000 includes opposite first side S1 and second side S2. The cardboard structure 1000 includes a first plate member 110 and second plate members 120 disposed on opposite sides of the first plate member 110. As Figure 2 shown, the two second plate members 120 are bent relative to the first plate member 110 towards the first side S1 at least twice, so that the two second plate members 120 partially overlap to form Figure 3 the buffer structure 100 shown. It can be understood that the buffer structure 100 may include a top wall, a bottom wall disposed opposite to each other, and two side walls connecting the top wall and the bottom wall. Among them, the first plate member 110 of the cardboard structure 1000 forms the bottom wall of the buffer structure 100, and the two second plate members 120 respectively form the two side walls and the top wall of the buffer structure 100. The top wall thereof is formed by the partial overlap of a part of the two second plate members 120. The top wall, the bottom wall and the two side walls of the buffer structure 100 can enclose a buffer cavity. When the buffer structure 100 is placed in a packaging box, it can play a buffering role for the products in the packaging box.

[0037] As Figure 4 shown, the forming device includes a forming structure 10. The forming structure 10 includes two forming members 11 spaced apart from each other along the first direction Y. The two forming members 11 are movably disposed along the first direction Y and the second direction X. The two forming members 11 are respectively used to push the two second plate members 120 from the second side S2 of the two second plate members 120 towards the first side S1 along the second direction X and the first direction Y at least twice, so that the two second plate members 120 partially overlap. The first direction Y is perpendicular to the second direction X.

[0038] The first direction Y may be the direction in which the two forming members 11 approach or separate from each other, that is, the arrangement direction of the two forming members 11. The second direction X may be the thickness direction when the cardboard structure 1000 is placed between the two forming members 11. When the forming device is placed on a flat surface, the first direction Y may be the horizontal direction, and the second direction X may be the vertical direction.

[0039] In the forming device, two forming members 11 are arranged at a relative interval. Before the forming buffer structure 100, the cardboard structure 1000 can be placed between the two forming members 11, and the two second plate members 120 of the cardboard structure 1000 are respectively located above the two forming members 11 along the second direction X. That is, the two forming members 11 are respectively located on the second side S2 of the two second plate members 120. Therefore, when the forming member 11 moves along the second direction X, it can push the second plate member 120 to bend relative to the first plate member 110 toward the first side S1 from the second side S2 of the corresponding second plate member 120, so that the second plate member 120 is approximately in an upright state. Subsequently, the two forming members 11 move toward each other along the first direction Y, and the forming member 11 can continue to push the second plate member 120 to bend toward the first side S1 from the second side S2 of the corresponding second plate member 120 until the two second plate members 120 partially overlap, that is, the forming of the buffer structure 100 is realized. It can be understood that before the cardboard structure 1000 is placed between the two forming members 11, a colloid can be provided on at least one of the two second plate members 120 in advance. The colloid can be double-sided tape or glue applied by a dispensing machine, etc. Therefore, when the two forming members 11 respectively push the two second plate members 120 to bend until they partially overlap, the two second plate members 120 can be adhered to each other to improve the structural reliability of the buffer structure 100. It should be clear that the two forming members 11 are movably arranged along the first direction Y and the second direction X, which means that at least part of the forming member 11 is movably arranged along the above directions. That is to say, the forming member 11 can move as a whole, or part of the forming member 11 can move relative to the rest of the forming member 11. This embodiment does not make a limitation.

[0040] In the embodiment of the present application, the forming device includes a forming structure 10. The forming structure 10 includes two relatively arranged forming members 11. The two forming members 11 are movably arranged along the first direction Y and the second direction X. Therefore, the cardboard structure 1000 is placed between the two forming members 11. The two forming members 11 respectively push the two second plate members 120 to bend relative to the first plate member 110 toward the first side S1 from the second side S2 of the two second plate members 120 along the second direction X first, so that the two second plate members 120 are both approximately in an upright state relative to the first plate member 110. Subsequently, the two forming members 11 push the two second plate members 120 toward each other along the first direction Y from the second side S2 of the two second plate members 120, so that the two second plate members 120 continue to bend toward the first side S1 until they partially overlap to form the buffer structure 100, realizing the automatic forming of the buffer structure 100, which can improve the production efficiency of the buffer structure 100 and reduce the labor and material costs in the production process of the buffer structure 100 at the same time.

[0041] It should be clear that the cardboard structure 1000 can be a pre-folded cardboard structure 1000 with creases. For example, a first crease can be formed between the first plate member 110 and the second plate member 120 to facilitate the forming member 11 to push the second plate member 120 to bend. Of course, the cardboard structure 1000 can also be a cardboard structure 1000 without pre-folding operation, which is not limited in this embodiment.

[0042] Please refer to Figure 5 , according to the first aspect of the present application, the forming device further includes a fixing structure 41. The fixing structure 41 is provided with negative pressure holes along the second direction X, and the fixing structure 41 is used to be arranged on the first side S1 of the first plate member 110 to limit the first plate member 110.

[0043] The fixing structure 41 is provided with negative pressure holes along the second direction X, and the negative pressure holes can be communicated with a negative pressure device. Therefore, by arranging the fixing structure 41 on the first side S1 of the first plate member 110, the negative pressure holes of the fixing structure 41 can suck the first plate member 110 to limit the first plate member 110, so as to facilitate the forming member 11 to push the second plate member 120 to bend relative to the first plate member 110.

[0044] Moreover, the shape of the fixing structure 41 can be adapted to the shape of the buffer cavity of the buffer structure 100. For example, when the buffer cavity is square, the outer shape of the fixing structure 41 can be square, and when the buffer cavity is cylindrical, the outer shape of the fixing structure 41 can be cylindrical. Therefore, during the forming process of the buffer structure 100, the fixing structure 41 can also serve as an inner forming mold of the buffer structure 100 to shape the second plate member 120 during the bending process of the second plate member 120, so that the second plate member 120 can be bent to form a buffer structure 100 with a corresponding shape.

[0045] It can be understood that the fixing structure 41 is arranged on the first side S1 of the first plate member 110. Therefore, when the second plate member 120 bends relative to the first plate member 110 towards the first side S1 and forms the buffer structure 100, the fixing structure 41 is located in the buffer cavity of the buffer structure 100.

[0046] As Figure 5 shown, according to the first aspect of the present application, the forming device further includes at least one of a defoaming structure 20 and a blanking structure 30 and a first transportation structure 40. The first transportation structure 40 is rotatably arranged around a first axis extending along the second direction X and is connected to the fixing structure 41. At least one of the defoaming structure 20 and the blanking structure 30 and the forming structure 10 are arranged at intervals on the outer peripheral side of the first transportation structure 40. The first transportation structure 40 is used to drive the fixing structure 41 to move between at least one of the defoaming structure 20 and the blanking structure 30 and the forming structure 10.

[0047] As Figure 6As shown, the defoaming structure 20 may include two pressing plates 21 oppositely arranged along the first direction Y. The two pressing plates 21 are movably arranged along the first direction Y. Therefore, by placing the buffer structure 100 between the two pressing plates 21 and moving the two pressing plates 21 towards each other, the buffer structure 100 can be squeezed to remove the bubbles in the colloid used to bond the two second plate members 120 in the buffer structure 100. The blanking structure 30 is used to transport the buffer structure 100 to the corresponding storage member or to the downstream equipment. The first transportation structure 40 is used to transport the buffer structure 100 to the defoaming structure 20 and / or the blanking structure 30. Specifically, the first transportation structure 40 is connected to the fixing structure 41. Therefore, during the rotation of the first transportation structure 40 around the first axis extending in the second direction X, it can drive the fixing structure 41 and the buffer structure 100 on the fixing structure 41 to rotate around the first axis together. At least one of the defoaming structure 20 and the blanking structure 30 and the forming structure 10 are arranged at intervals on the outer peripheral side of the first transportation structure 40. Therefore, after the buffer structure 100 is formed at the forming structure 10, the first transportation structure 40 can drive the fixing structure 41 and the buffer structure 100 on the fixing structure 41 to move to the defoaming structure 20 and / or the blanking structure 30 around the first axis for defoaming operation and / or blanking operation, so as to realize the automatic transportation, automatic defoaming and automatic blanking of the buffer structure 100, which can further improve the production efficiency of the buffer structure 100. At the same time, it can also make the structure between at least one of the defoaming structure 20 and the blanking structure 30 and the forming structure 10 more compact, so as to reduce the overall volume of the forming equipment.

[0048] It can be understood that since the fixing structure 41 and the buffer structure 100 are transported to the defoaming structure 20 and / or the blanking structure 30 together by the first transportation structure 40, during the defoaming process, the buffer structure 100 can be supported in the buffer cavity of the buffer structure 100 through the fixing structure 41 to prevent the buffer structure 100 from deforming under the extrusion of the pressing plates 21.

[0049] It should be clear that when the defoaming structure 20 is provided in the forming equipment, the first transportation structure 40 can transport the formed buffer structure 100 in the forming structure 10 to the defoaming structure 20. When the blanking structure 30 is provided in the forming equipment, the first transportation structure 40 can transport the formed buffer structure 100 in the forming structure 10 to the blanking structure 30. When both the defoaming structure 20 and the blanking structure 30 are provided in the forming equipment, the first transportation structure 40 first transports the formed buffer structure 100 in the forming structure 10 to the defoaming structure 20 for defoaming treatment, and then transports the defoamed buffer structure 100 to the blanking structure 30.

[0050] Optionally, the number of the fixing structures 41 can be multiple. The multiple fixing structures 41 are respectively connected to the first transportation structure 40. When the first transportation structure 40 moves the fixing structure 41 at the forming structure 10 to the defoaming structure 20 and / or the blanking structure 30, another fixing structure 41 can be synchronously moved by the first transportation structure 40 to the forming structure 10 to continue to limit the cardboard structure 1000 at the forming structure 10, so that the forming process of the buffer structure 100 can be continuously and uninterruptedly realized.

[0051] Moreover, before the fixing structure 41 is moved to the forming structure 10, it can first suck the cardboard structure 1000 to be formed at a preset loading position, so as to transport the cardboard structure 1000 to the forming structure 10 for forming operation under the drive of the first transportation structure 40. Therefore, there is no need to additionally provide a loading mechanism or manually load by workers, so as to further save costs.

[0052] Please continue to refer to Figure 5 , according to the first aspect of the present application, the first transportation structure 40 includes a driving member 421 and a turntable 422 arranged on the driving member 421. The driving member 421 is used to drive the turntable 422 to rotate around the first axis. The turntable 422 is connected to the fixing structure 41. At least one of the defoaming structure 20 and the blanking structure 30 is arranged downstream of the forming structure 10 along the rotation direction of the first transportation structure 40.

[0053] Optionally, the fixing structure 41 can include a first connecting member and a second connecting member. The first connecting member is provided with a negative pressure hole for connecting to the first plate member 110. The second connecting member is used to connect to the turntable 422. The first connecting member and the second connecting member can be fixedly connected by bolts, with a simple structure and convenient assembly.

[0054] The turntable 422 rotates around the first axis under the drive of the driving member 421. At the same time, the turntable 422 is connected to the fixing structure 41, so it can drive the fixing structure 41 and the buffer structure 100 on the fixing structure 41 to rotate around the first axis, with a simple structure and stable transmission. Since at least one of the defoaming structure 20 and the blanking structure 30 is arranged downstream of the forming structure 10 along the rotation direction of the first transportation structure 40, when the buffer structure 100 at the forming structure 10 is formed, the driving member 421 can drive the fixing structure 41 and the buffer structure 100 on the fixing structure 41 to rotate to the defoaming structure 20 and / or the blanking structure 30 through the turntable 422.

[0055] It should be clear that in this application, upstream and downstream are relative terms. Upstream refers to the end or a section of distance that the buffer structure 100 or the cardboard structure 1000 passes through first during transportation relative to the downstream. Downstream refers to the end or a section of distance that the buffer structure 100 or the cardboard structure 1000 needs to pass through after passing through the upstream. That is to say, during the forming process of the buffer structure 100, the direction from upstream to downstream is the transportation direction of the buffer structure 100 or the cardboard structure 1000.

[0056] Please continue to refer to Figure 6 , optionally, the defoaming structure 20 may further include at least two first displacement members 22, which drive the pressing plate 21 to move along the first direction Y. The first displacement members 22 may include any components capable of linear drive such as cylinders, linear motors, and guide rail assemblies, which are not limited in this embodiment.

[0057] As Figure 7 shown, the blanking structure 30 includes a guiding assembly 31 and a grasping assembly 32 provided on one side of the guiding assembly 31 along the second direction X. A guiding groove 311 is formed on the side of the guiding assembly 31 facing the grasping assembly 32. The grasping assembly 32 is used to grasp the buffer structure 100 into the guiding groove 311, so as to guide the buffer structure 100 through the guiding groove 311 and realize the blanking of the buffer structure 100.

[0058] Optionally, the guiding assembly 31 includes a guiding member and a bracket connected to the guiding member. The bracket is used to support the guiding member, and the guiding member forms the above-mentioned guiding groove 311. Part of the guiding member is inclined along the second direction X relative to the rest of the guiding member, so that the bottom wall of the guiding groove 311 forms an inclined surface to facilitate blanking.

[0059] Optionally, the grasping assembly 32 includes a second displacement member 321 and a clamping jaw 322. The second displacement member 321 is used to drive the clamping jaw 322 to move. The clamping jaw 322 includes a cylinder and two clamping blocks. The cylinder includes a cylinder body and two pistons arranged on opposite sides of the cylinder body. The two clamping blocks are respectively arranged on the two pistons to approach or separate from each other through the two pistons, so as to be able to clamp the buffer structure 100.

[0060] Please continue to refer to Figure 4 , according to the first aspect of this application, one of the two forming members 11 includes a first bracket 111 and a roller 112 provided on the first bracket 111. The roller 112 is located on one side of the first bracket 111 close to the other forming member 11 along the first direction Y. The axis of the roller 112 extends along the third direction Z, and the third direction Z is perpendicular to the first direction and the second direction respectively.

[0061] It can be understood that when the cardboard structure 1000 is placed between the two forming members 11, the first direction Y can be one of the length direction or the width direction of the cardboard structure 1000, and the third direction Z can be the other one.

[0062] In this embodiment, the roller 112 pushes the second plate member 120 from the second side S2 of the second plate member 120. Rolling friction occurs between the forming member 11 and the second plate member 120, which can reduce the damage of the forming member 11 to the second plate member 120.

[0063] Please continue to refer to Figure 4 , and / or, one of the two forming members 11 includes a second bracket 113 and a pushing plate 114 arranged on the second bracket 113. The pushing plate 114 is arranged close to the other forming member 11 along the first direction Y. The thickness of the pushing plate 114 along the second direction X gradually decreases from the side away from the other forming member 11 to the side close to the other forming member 11.

[0064] It can be understood that during the forming process of the buffer structure 100, the pushing plate 114 can first push the corresponding second plate member 120 to bend to a preset forming position, and then the other forming member 11 pushes the corresponding second plate member 120 to bend to the preset forming position. During the process of the other forming member 11 pushing the second plate member 120, the pushing plate 114 can perform a reset action synchronously, so as to avoid affecting the overlapping effect of the two second plate members 120. The thickness of the pushing plate 114 along the second direction X gradually decreases from the side away from the other forming member 11 to the side close to the other forming member 11. Therefore, when the pushing plate 114 performs a reset action and the other forming member 11 pushes its corresponding second plate member 120 to bend to the preset forming position, the risk of positional interference between the pushing plate 114 and the other forming member 11 can be reduced, and the collision between the two can be avoided, thus affecting the service life.

[0065] Please continue to refer to Figure 4 , optionally, the forming structure 10 further includes a driving module 12. The driving module 12 includes a support plate 121, a first cylinder 122 and two second cylinders 123. The piston of the first cylinder 122 extends along the first direction Y. The support plate 121 is connected to the piston of the first cylinder 122. The two forming members 11 and the two second cylinders 123 are both arranged on the support plate 121. Among them, the two second cylinders 123 are connected to the two forming members 11 in a one-to-one correspondence. The piston of the second cylinder 123 extends along the second direction X to drive the corresponding forming member 11 to move along the second direction X. And through the first cylinder 122, the support plate 121 and the forming members 11 and the second cylinders 123 located on the support plate 121 can be integrally driven to move along the first direction Y. Compared with setting two cylinders to drive the two second cylinders 123 and the two forming members 11 to move along the first direction Y in a one-to-one correspondence, the number of cylinders can be reduced and the cost can be saved.

[0066] Please continue to refer to Figure 1 According to the first aspect of the present application, the second plate member 120 includes a first sub-plate 130 and a second sub-plate 140 sequentially arranged in a direction away from the first plate member 110. The first sub-plate 130 is bent at least once relative to the first plate member 110 toward the first side S1, and the second sub-plate 140 is bent at least once relative to the first sub-plate 130 toward the first side S1. At least a part of the second sub-plates 140 of the two second plate members 120 overlap to form a buffer structure 100.

[0067] A first crease may be formed between the first sub-plate 130 and the first plate member 110, and a second crease may be formed between the second sub-plate 140 and the first sub-plate 130. During the forming process of the buffer structure 100, the two forming members 11 first push the corresponding first sub-plates 130 along the second direction X from the second side S2 of the two first sub-plates 130, so that the first sub-plates 130 are bent relative to the first plate member 110 toward the first side S1 until they are approximately in an upright state. Subsequently, the two forming members 11 push the corresponding second sub-plates 140 along the first direction Y from the second side S2 of the two second sub-plates 140 toward the side close to each other, so that the second sub-plates 140 are bent relative to the first sub-plates 130 toward the first side S1 until they are approximately in a horizontal state. At this time, at least a part of the two second sub-plates 140 may overlap. It can be understood that when a colloid is provided on at least one of the two second plate members 120, the colloid may be located on the second sub-plate 140, so that the two second sub-plates 140 can be bonded by the colloid when they at least partially overlap.

[0068] As Figure 8 shown, the forming device further includes a pre-folding structure 50 spaced apart from the forming structure 10. The pre-folding structure 50 includes a first pre-folding assembly 51 and a second pre-folding assembly 52. The first pre-folding assembly 51 includes two first pre-folding members 511 spaced apart relatively. The two first pre-folding members 511 are respectively used to drive the two first sub-plates 130 to be bent relative to the first plate member 110 toward the first side S1. The second pre-folding assembly 52 includes two second pre-folding members 521 spaced apart relatively. The two second pre-folding members 521 are respectively used to drive the two second sub-plates 140 to be bent relative to the first sub-plates 130 toward the first side S1.

[0069] The pre-folding structure 50 is arranged at an interval from the forming structure 10, and it can be located upstream of the forming structure 10. After being pre-folded by the pre-folding structure 50, the cardboard structure 1000 is transported to the forming structure 10 for forming to form the corresponding buffer structure 100. Specifically, the first pre-folding assembly 51 is used to pre-fold the first sub-board 130 so as to form a first crease between the first sub-board 130 and the first board member 110, and the second pre-folding assembly 52 is used to pre-fold the second sub-board 140 so as to form a second crease between the second sub-board 140 and the first sub-board 130, thereby reducing the difficulty of the forming member 11 pushing the corresponding board member to bend and improving the forming efficiency.

[0070] In the first pre-folding assembly 51, two first pre-folding members 511 respectively correspond to two first sub-boards 130, and are respectively used to push the two first sub-boards 130 to bend relative to the first board member 110 to form a first crease. In the second pre-folding assembly 52, two second pre-folding members 521 respectively correspond to two second sub-boards 140, and are respectively used to push the two second sub-boards 140 to bend relative to the first sub-board 130 to form a second crease.

[0071] Optionally, the first pre-folding member 511 and the second pre-folding member 521 can include any components capable of driving the board member to bend, such as clamping jaws, push plates, rollers, etc. The first pre-folding member 511 and the second pre-folding member 521 can have the same structure or different structures, which is not limited in this embodiment.

[0072] Please continue to refer to Figure 8 , according to the first aspect of the present application, the first pre-folding member 511 includes a push rod 512 rotatably arranged around a second axis and a pre-folding plate 513 rotatably arranged around a third axis. The extending direction of the second axis is parallel to the extending direction of the third axis. The pre-folding plate 513 is connected to the push rod 512. The push rod 512 is used to push the pre-folding plate 513 to rotate around the third axis, and the pre-folding plate 513 is used to push the first sub-board 130 to flip from the second side S2 of the corresponding first sub-board 130, so that the first sub-board 130 bends relative to the first board member 110 toward the first side S1.

[0073] Specifically, during pre-folding, the cardboard structure 1000 is placed between two first pre-folding members 511, and the two first sub-boards 130 are respectively located above the pre-folding plates 513 of the two first pre-folding members 511, that is, the pre-folding plates 513 of the two first pre-folding members 511 are respectively located on the second side S2 of the two first sub-boards 130. When the push rod 512 pushes the pre-folding plate 513 to flip, the pre-folding plate 513 can drive the corresponding first sub-board 130 to flip relative to the first board member 110 to form a first crease between the first sub-board 130 and the first board member 110, realizing the pre-folding of the first sub-board 130. The structure is simple and the operation is convenient.

[0074] Optionally, the first pre-folding member 511 may further include a rotational drive mechanism such as a rotational motor to drive the push rod 512 to rotate.

[0075] Please continue to refer to Figure 8 , and / or, the second pre-folding assembly 52 is disposed downstream of the first pre-folding assembly 51. The second pre-folding member 521 includes a linear drive member 522 and a roller 523 connected to the linear drive member 522. The rollers 523 of the two second pre-folding members 521 are movably disposed in a direction approaching or separating from each other. The roller 523 is configured to push the second sub-board 140 to flip from the second side S2 of the corresponding second sub-board 140, so that the second sub-board 140 is bent relative to the first sub-board 130 toward the first side S1.

[0076] Specifically, the second pre-folding assembly 52 is disposed downstream of the first pre-folding assembly 51. After the first pre-folding assembly 51 pre-folds the first sub-board 130, the second pre-folding assembly 52 pre-folds the second sub-board 140. It can be understood that after the first sub-board 130 is pre-folded by the first pre-folding assembly 51, it can be bent relative to the first board member 110. During pre-folding, by placing the cardboard structure 1000 between the two second pre-folding members 521 and making the rollers 523 of the two second pre-folding members 521 be respectively located on the second side S2 of the two second sub-boards 140, when the linear drive members 522 of the two second pre-folding members 521 drive the rollers 112 to move in a direction approaching each other, the two rollers 112 can push the corresponding second sub-board 140 from the second side S2 of the two second sub-boards 140 to bend relative to the corresponding first sub-board 130 toward the first side S1, so that a second crease is formed between the second sub-board 140 and the first sub-board 130, realizing the pre-folding of the second sub-board 140. The structure is simple and the operation is convenient.

[0077] Optionally, the second pre-folding member 521 may further include a linear drive mechanism such as a cylinder, a hydraulic cylinder, and a linear motor to drive the corresponding roller 112 to move.

[0078] Please continue to refer to Figure 8 , according to the first aspect of the present application, the forming device further includes a limiting structure. The limiting structure includes a limiting block 53 movably disposed along the second direction X. The limiting block 53 is located between the two first pre-folding members 511 and / or between the two second pre-folding members 521. The limiting block 53 is configured to be disposed on the first side S1 of the first board member 110 to limit the first board member 110.

[0079] Specifically, when the cardboard structure 1000 is placed between the two first pre-folding members 511 or between the two second pre-folding members 521, the limiting block 53 can be moved along the second direction X to the first side S1 of the first board member 110, so that the limiting block 53 limits the first board member 110 along the second direction X to prevent its position from shifting during subsequent pre-folding, thereby improving the pre-folding accuracy.

[0080] Further, the shape of the limiting block 53 can be adapted to the shape of the buffer structure 100 to be formed by the cardboard structure 1000. Therefore, during the pre-folding process, the limiting block 53 can also be used as a supporting inner mold to shape the cardboard structure 1000 during the pre-folding process of the cardboard structure 1000, so that after pre-folding, the first sub-board 130 and the second sub-board 140 can form a buffer structure 100 with a preset shape in the forming structure 10.

[0081] Optionally, the limiting structure may further include linear driving mechanisms such as air cylinders, hydraulic cylinders, and linear motors for driving the limiting block 53 to move along the second direction X.

[0082] Optionally, when limiting blocks 53 are provided between the two first pre-folding members 511 and the two second pre-folding members 521, the two limiting blocks 53 can be an integrally formed structure 10. Therefore, when transporting the cardboard structure 1000 between the first pre-folding assembly 51 and the second pre-folding assembly 52, the cardboard structure 1000 can be guided by the limiting block 53, reducing the risk of its position deviation and improving the pre-folding accuracy.

[0083] As Figure 9 shown, according to the first aspect of the present application, the forming device further includes a second transportation structure 60 for transporting the cardboard structure 1000 along the fourth direction Y'. The first pre-folding assembly 51 and the second pre-folding assembly 52 are arranged at intervals along the fourth direction Y'. The first pre-folding assembly 51 and the second pre-folding assembly 52 are both on opposite sides of the second transportation structure 60. Thus, the second transportation structure 60 can transport the buffer structure 100 to be formed between the first pre-folding assembly 51 and the second pre-folding assembly 52 to improve the pre-folding efficiency.

[0084] It should be clear that the first direction Y is perpendicular to the fourth direction Y'. Among them, the first direction Y can be the height direction of the second transportation structure 60, and the fourth direction Y' can be the length direction of the second transportation structure 60. In the first pre-folding assembly 51, the two first pre-folding members 511 are respectively arranged on opposite sides of the second transportation structure 60. In the second pre-folding assembly 52, the two second pre-folding members 521 are respectively arranged on opposite sides of the second transportation structure 60. Therefore, during the transportation of the cardboard structure 1000 by the second transportation structure 60, the cardboard structure 1000 can be located between the two first pre-folding members 511 and between the two second pre-folding members 521.

[0085] Optionally, the second transportation structure 60 can be driven by any transmission method such as belt drive, chain drive, and roller drive, which is not limited in this embodiment.

[0086] Please continue to refer to Figure 9, according to the first aspect of the present application, the second transportation structure 60 includes a transportation component 61 and a plurality of connection components 62 for connecting the cardboard structure 1000. The plurality of connection components 62 are arranged in sequence along the fourth direction Y', and are movably arranged relative to the transportation component 61 along the fourth direction Y'. The forming device further includes a carrier 70, the pre-folding structure 50 is arranged on the carrier 70, a receiving cavity 71 is formed inside the carrier 70, an opening is formed on one side of the carrier 70 facing the pre-folding structure 50 along the second direction X, the second transportation structure 60 is arranged in the receiving cavity 71, and the opening exposes the second transportation structure 60, wherein the connection component 62 is configured to be telescopically arranged along the second direction X.

[0087] The connection component 62 is arranged on the transportation component 61 and is used to drive the cardboard structure 1000 to move along the second direction X under the transportation of the transportation component 61. In this embodiment, the plurality of connection components 62 are transported simultaneously by the transportation component 61, which can save transportation costs. Moreover, the cardboard structure 1000 can be transported at multiple positions such as between the first pre-folding component 51 and the second pre-folding component 52, and between the second pre-folding component 52 and the forming structure 10 by the plurality of connection components 62, so that the first pre-folding component 51 and the second pre-folding component 52 can pre-fold different cardboard structures 1000 at the same time, that is, the first pre-folding component 51 and the second pre-folding component 52 can continuously pre-fold the cardboard structure 1000 without interruption to improve the pre-folding efficiency. For example, when the pre-folding of the cardboard structure 1000 connected by a connection component 62 is completed at the first pre-folding component 51, the connection component 62 drives the corresponding cardboard structure 1000 to move to the second pre-folding component 52 for pre-folding. At the same time, another connection component 62 drives its corresponding cardboard structure 1000 to move to the first pre-folding component 51 for pre-folding.

[0088] The stage 70 is used to carry the pre-folding assembly and the second transportation structure 60. Specifically, one side of the stage 70 along the first direction Y has a bearing surface, and an accommodation cavity 71 can be formed inside it. The pre-folding structure 50 is arranged on the bearing surface of the stage 70, and the second transportation structure 60 is arranged in the accommodation cavity 71 formed inside the stage 70, thereby improving the space utilization rate on the stage 70 and making the structure of the forming device more compact. It can be understood that when the pre-folding structure 50 is arranged on the bearing surface of the stage 70, the side of the stage 70 facing the pre-folding structure 50 is the side where the bearing surface is located, that is to say, an opening is provided on the bearing surface of the stage 70 to expose the second transportation structure 60 located in the accommodation cavity 71. The connecting component 62 is telescopically arranged along the second direction X. Therefore, when the connecting component 62 is connected to the cardboard structure 1000 and drives the cardboard structure 1000 to move along the fourth direction Y', by extending the connecting component 62 along the second direction X, the cardboard structure 1000 can be spaced from the bearing surface of the stage 70 along the second direction X to avoid rubbing between the cardboard structure 1000 and the bearing surface of the stage 70.

[0089] Optionally, the transportation component 61 may include a slide rail extending along the fourth direction Y' and a slider slidably arranged on the slide rail. The connecting component 62 is connected to the slider, so it can move along the fourth direction Y'. The structure is simple and the transmission is stable.

[0090] The connecting component 62 may include a suction cup body 621 and a telescopic rod 622. The telescopic rod 622 is telescopically arranged along the second direction X. The suction cup body 621 is connected to the transportation component 61 through the telescopic rod 622 to realize the telescopic arrangement of the connecting component 62 along the second direction X. The suction cup body 621 includes a plurality of suction cups, and the plurality of suction cups are respectively used to suck the first plate member 110 of the cardboard structure 1000 to drive the cardboard structure 1000 to move. Of course, the transportation component 61 and the connecting component 62 may also be other structures. For example, the transportation component 61 may further include transportation components such as a conveyor belt, a conveyor chain, and a conveyor roller, and the connecting component 62 may include a grasping component such as a clamping jaw. This embodiment is not limited.

[0091] As Figure 10 shown, according to the first aspect of the present application, the forming device further includes a positioning structure 80 arranged on one side of the second transportation structure 60. The positioning structure 80 is located upstream of the pre-folding structure 50. The positioning structure 80 includes two first positioning members 81 oppositely arranged along the fourth direction Y' and two second positioning members 82 oppositely arranged along the fifth direction Z'. Among them, the distance between the two first positioning members 81 along the fourth direction Y' is adjustable, and the distance between the two second positioning members 82 along the fifth direction Z' is adjustable. The fifth direction Z' is perpendicular to the first direction Y and the fourth direction Y' respectively.

[0092] The fifth direction Z' can be the width direction of the second transportation structure 60. The positioning structure 80 is located upstream of the pre-folding structure 50. Therefore, the cardboard structure 1000 can be positioned at the positioning structure 80 and then transported to the pre-folding structure 50 for pre-folding, which can improve the position accuracy of the cardboard structure 1000, and further improve the pre-folding accuracy and forming accuracy.

[0093] Specifically, in the positioning structure 80, the two first positioning members 81 are spaced apart along the fourth direction Y'. The two second positioning members 82 are spaced apart along the fifth direction Z'. Thus, a preset placement position for placing the cardboard structure 1000 can be formed between the two first positioning members 81 and the two second positioning members 82. When the cardboard structure 1000 is placed in the aforementioned preset placement position, the two first positioning members 81 can clamp the buffer structure 100 along the fourth direction Y', and the two second positioning members 82 can clamp the buffer structure 100 along the fifth direction Z', thereby realizing the positioning of the buffer structure 100. It can be understood that in this embodiment, the adjustable setting of the distance between the two first positioning members 81 along the fourth direction Y' means that at least one of the two first positioning members 81 can move in a direction approaching or moving away from each other. The adjustable setting of the distance between the two second positioning members 82 along the fifth direction Z' means that at least one of the two second positioning members 82 can move in a direction approaching or moving away from each other.

[0094] In this embodiment, by setting the adjustable distance between the two first positioning members 81 along the fourth direction Y' and the adjustable distance between the two second positioning members 82 along the fifth direction Z', the dimensions of the preset placement position along the fourth direction Y' and the fifth direction Z' can be adjusted, improving the applicable range of the positioning structure 80. At the same time, before positioning the cardboard structure 1000, by increasing the size of the preset placement position, it is also convenient to place the cardboard structure 1000 into the above-mentioned preset placement position, reducing the positioning difficulty.

[0095] It can be understood that when the forming device includes the positioning structure 80, the number of connection components 62 in the second transportation structure 60 can be three. The three connection components 62 are respectively arranged in one-to-one correspondence with the positioning structure 80, the first pre-folding component 51, and the second pre-folding component 52. Therefore, the positioning structure 80, the first pre-folding component 51, and the second pre-folding component 52 can position or pre-fold three cardboard structures 1000 at the same time, which can further improve the production efficiency of the buffer structure 100.

[0096] Optionally, the positioning structure 80 further includes at least one third cylinder and at least one fourth cylinder. The third cylinder is connected to the first positioning member 81 and is used to drive the first positioning member 81 to move along the fourth direction Y'. The fourth cylinder is connected to the second positioning member 82 and is used to drive the second positioning member 82 to move along the fifth direction Z'.

[0097] Optionally, the positioning structure 80 can be arranged on the stage 70. Two second positioning members 82 can be arranged on both sides of the opening of the stage 70 along the fifth direction Z'. One of the two first positioning members 81 can be arranged on the side of the opening away from the pre-folding structure 50 along the fourth direction Y', and the other covers a part of the opening, that is, at least part of the preset placement position is located at the opening, so that the connecting component 62 of the second transportation structure 60 can move to the preset placement position and be connected to the cardboard structure 1000 after the positioning of the cardboard structure 1000 is completed.

[0098] The positioning structure 80 further includes a fifth air cylinder, which is connected to one of the two first positioning members 81 close to the pre-folding structure 50 and the corresponding third air cylinder of this first positioning member 81, and is used to drive this first positioning member 81 and the corresponding third air cylinder to move along the fifth direction Z'. When the positioning of the cardboard structure 1000 is completed, the connecting component 62 can drive the positioned cardboard structure 1000 to move to the pre-folding structure 50 along the fourth direction Y' for pre-folding. At this time, the fifth air cylinder can drive one of the two first positioning members 81 close to the pre-folding mechanism and the corresponding third air cylinder to move along the fifth direction Z' to avoid the first positioning member 81 and the corresponding third air cylinder from blocking the movement of the positioned cardboard structure 1000.

[0099] Please continue to refer to Figure 10 , according to the first aspect of the present application, the forming device further includes a feeding structure 90. The feeding structure 90 includes a suction cup assembly 91. The suction cup assembly 91 is movably arranged along at least one of the fourth direction Y' and the fifth direction Z' and the second direction X, and is used to transport the cardboard structure 1000 to the positioning structure 80, so as to realize the automatic feeding of the cardboard structure 1000 and improve the production efficiency of the buffer structure 100.

[0100] Optionally, the feeding structure 90 can further include at least one of a first slide rail mechanism 92 and a second slide rail mechanism and a third slide rail mechanism 93. The first slide rail mechanism 92 is used to drive the suction cup assembly 91 to move along the fourth direction Y', the second slide rail mechanism is used to drive the suction cup assembly 91 to move along the fifth direction Z', and the third slide rail mechanism 93 is used to drive the suction cup assembly 91 to move along the second direction X. Thus, the suction cup assembly 91 sucks the cardboard structure 1000 and drives the cardboard structure 1000 to move, realizing the automatic feeding of the cardboard structure 1000. The structure is simple and the transmission is stable.

[0101] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
