[0035] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0036] Paper packaging boxes and their internal paper components are usually formed by bending and bonding cardboard. Currently, the forming methods are usually manual operation methods or semi-automatic production line methods, and manual operation is required during the cardboard forming process. However, the adhesive required for bonding causes damage to the operator's body.

[0037] As Figures 1 to 14 shown, an embodiment of the present application provides a forming device, which is used to form a to-be-formed structure 100. The forming device includes: a pre-bending assembly 200, which is used to bend the to-be-formed structure 100 multiple times to form a bent structure 300, so that the bent structure 300 has at least one bent portion 120 connected in multiple segments by bending. The bent structure 300 further includes a mounting portion 110, and the bent portion 120 can enclose an assembly portion 130 with a part of the mounting portion 110; an adhesive application assembly 20, which is used to apply an adhesive on the surface of the mounting portion 110 to form an adhesive portion 140; a forming assembly 40, which is arranged downstream of the pre-bending assembly 200 and the adhesive application assembly 20, and includes at least one rotatable flipping member 42. The flipping member 42 is movably arranged along a direction perpendicular to its own rotation direction, and is used to insert into the assembly portion 130 and rotate the assembly portion 130, so that the assembly portion 130 is bonded to the adhesive portion 140 to form a formed structure 400. Wherein, the moving direction of the flipping member 42 is the inserting direction when it inserts into the assembly portion 130, which is the third direction Z in the present application; the rotation direction of the flipping member 42 is the direction in which it drives the assembly portion 130 to rotate, and in the present application, the rotation direction is perpendicular to the third direction Z.

[0038] It should be noted that the to-be-formed structure 100 is a cardboard structure. After the assembly portion 130 is bonded to the adhesive portion 140, the overall structure is formed to form a formed structure 400, that is, a buffer member arranged inside the packaging box. After an object is placed in the packaging box, it can be blocked from the side wall of the packaging box through the formed cardboard structure, avoiding damage to the internal object due to collision during transportation of the packaging box. In the embodiment of the present application, the to-be-formed structure 100 is bent to form a bent structure 300. The bent structure 300 has a mounting portion 110 and two bent portions 120, and the two bent portions 120 are respectively connected to opposite sides of the mounting portion 110.

[0039] In specific implementation, the forming device of the embodiment of the present application includes a pre-bending assembly 200, an adhesive bonding assembly 20, and a forming assembly 40. The forming assembly 40 includes at least one rotatable flipping member 42. The pre-bending assembly 200 can bend the to-be-formed structure 100 to form a bent portion 120. After the bent portion 120 is bent and formed, it can enclose an assembly portion 130 with the mounting portion 110. During the bending process, the adhesive bonding assembly 20 will also apply an adhesive on the surface of the mounting portion 110 at the same time, so that a part of the mounting portion 110 forms an adhesive bonding portion 140. The flipping member 42 is arranged behind the adhesive bonding assembly 20 and can insert into the assembly portion 130 and drive the assembly portion 130 to flip, so that the side of the flipped assembly portion 130 facing the adhesive bonding portion 140 is bonded to the adhesive bonding portion 140, forming a formed structure 400 with integral forming as shown in Figure 13 shown, and completing the full-automatic forming of the to-be-formed structure 100. Therefore, the forming device of the present application adopts the cooperation of the pre-bending assembly 200, the adhesive bonding assembly 20, and the forming assembly 40, realizes the cooperation of the bending, glue application, and flipping and bonding processes of the to-be-formed structure 100, enables the to-be-formed structure 100 to be fully automatically formed, improves the production efficiency and production yield, and can also reduce manual operations and avoid physical injuries to operators.

[0040] For the forming device of the embodiment of the present application, among them, the pre-bending assembly 200 includes a plurality of pre-bending mechanisms arranged in sequence. The plurality of pre-bending mechanisms are used to respectively bend the to-be-formed structure 100 during the movement of the to-be-formed structure 100 and form a bent portion 120 with multi-segment bending connection; the adhesive bonding assembly 20 is arranged between two adjacent pre-bending mechanisms and is used to apply an adhesive during the bending process of the to-be-formed structure 100.

[0041] In specific implementation, the plurality of pre-bending mechanisms can sequentially bend the to-be-formed structure 100 to form a bent portion 120, so that the bent portion 120 can enclose an assembly portion 130 with a part of the mounting portion 110, and the assembly portion 130 forms a structure with a hollow interior. After the to-be-formed structure 100 is formed and the formed structure 400 is installed inside the packaging box, the assembly portion 130 can have a buffering effect on the items placed inside the packaging box to protect the items; the adhesive bonding assembly 20 is arranged between any two adjacent pre-bending mechanisms, and applies an adhesive on the mounting portion 110 during the bending process of the assembly portion 130, so that the assembly portion 130 can be bonded to the adhesive bonding portion 140 of the mounting portion 110 after being completely bent and formed, so as to achieve integral assembly and ensure the coherence and automation of each process.

[0042] As Figures 1 to 13As shown, the forming device of the first embodiment of the present application, wherein the pre-bending assembly 200 includes a first pre-bending mechanism 10, a second pre-bending mechanism 30, and a third pre-bending mechanism 41 arranged in sequence. The first pre-bending mechanism 10, the second pre-bending mechanism 30, and the third pre-bending mechanism 41 can sequentially perform at least three bends on the to-be-formed structure 100 to form a bent portion 120 with multiple bent connections of the bent structure 300.

[0043] In specific implementation, the pre-bending assembly 200 of the first embodiment of the present application includes a first pre-bending mechanism 10, a second pre-bending mechanism 30, and a third pre-bending mechanism 41 arranged in sequence, which can sequentially perform at least three bends on the to-be-formed structure 100, so that the bent portion 120 after bending and forming can form a prism structure with at least four edges with a part of the mounting portion 110, and can buffer articles of different shapes.

[0044] As Figure 4 shown, the forming device of the first embodiment of the present application, wherein the first pre-bending mechanism 10 includes a first pressing member 11 and a first blocking member 12. In a plane perpendicular to the first direction X, the projection of the first blocking member 12 is located outside the projection range of the first pressing member 11. The first blocking member 12 includes at least one first blocking portion 121 extending along the first direction X. At least one first blocking portion 121 is arranged in one-to-one correspondence with at least one bent portion 120. The first pressing member 11 is movably arranged along the first direction X for pressing the mounting portion 110 to be bent-connected to the bent portion 120.

[0045] It should be noted that the first direction X is the height direction of the whole forming device, and the first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other in pairs.

[0046] In specific implementation, in a plane perpendicular to the first direction X, the projection of the first blocking member 12 is located outside the projection range of the first pressing member 11, so that the first pressing member 11 can be arranged opposite to the mounting portion 110, and the first blocking member 12 can be arranged opposite to the bent portion 120. During the process of the first pressing member 11 driving the to-be-formed structure 100 to move towards the first blocking member 12 along the first direction X, the first blocking portion 121 can block its corresponding bent portion 120, so that the bent portion 120 bends towards the direction opposite to the moving direction of the first pressing member 11. As Figure 11 shown, the bent portion 120 is bent-connected to the mounting portion 110, which can prepare for further bending in the future.

[0047] Specifically, the first pressing member 11 is a plate-like structure perpendicular to the first direction X. The surface of the plate-like structure facing the mounting portion 110 has air holes, which can adsorb the mounting portion 110 and drive the mounting portion 110 to move. The first pre-bending mechanism 10 includes two first blocking members 12 arranged at intervals along the second direction Y. Both of the two first blocking members 12 are plate-like structures perpendicular to the second direction Y. Under the joint clamping of the first blocking member 12 and the first pressing member 11, the mounting portion 110 and the bending portion 120 are perpendicularly connected.

[0048] Optionally, both side surfaces of the first pressing member 11 facing the two first blocking members 12 form an angle with the first direction X, and the angles of each side surface with the corresponding side surface of the first blocking member 12 are the same. The two can cooperate. When the first pressing member 11 presses the to-be-formed structure 100 downward along the first direction X, the to-be-formed structure 100 can be bent, and the bending portion 120 is clamped between the first pressing member 11 and the first blocking member 12. Moreover, the bending angle of the bending portion 120 is the same as the angle of the side surface of the first pressing member 11. Therefore, the structures of the first pressing member 11 and the first blocking member 12 can be designed according to the bending angle required for the to-be-formed structure 100.

[0049] Specifically, the two first blocking members 12 are arranged on the mounting surface of the forming device, and the first pressing member 11 is movably arranged above the mounting surface of the forming device and can move along the first direction X under the driving action of the driving motor. Therefore, the forming device has a moving space along the first direction X.

[0050] As Figure 5 shown, in the forming device of the first embodiment of the present application, the pre-bending assembly 200 further includes a second pre-bending mechanism 30. The second pre-bending mechanism 30 is arranged behind the first pre-bending mechanism 10. The second pre-bending mechanism 30 includes at least one second pressing member 31. At least one second pressing member 31 is arranged in one-to-one correspondence with at least one bending portion 120. The second pressing member 31 is movably arranged along the second direction Y and is used for bending the bending portion 120 to form a first bending section 150 and a second bending section 160 that are bent and connected.

[0051] During specific implementation, when the second pressing member 31 moves along the second direction Y, it can abut against the surface of the bending portion 120 during the movement process to further bend the bending portion 120, so that the bending portion 120 forms a first bending section 150 and a second bending section 160 as Figure 12 shown, preparing for the final forming of the bending portion 120.

[0052] Specifically, the first bent section 150 and the second bent section 160 are perpendicularly connected. After the bent structure 300 is bent by the second pressing member 31 of the forming device, the first bent section 150 is perpendicular to the second direction Y, and the second bent section 160 is perpendicular to the first direction X.

[0053] Specifically, the second pressing member 31 is a cylindrical structure extending along the third direction Z. Driven by the driving motor, the second pressing member 31 can move along the second direction Y and push the bent portion 120 to be bent. During the contact with the bent portion 120, the second pressing member 31 of the cylindrical structure will rotate, so as to make the bending process smoother.

[0054] As Figure 2 shown, for the forming device of the first embodiment of the present application, the pre-bending assembly 200 further includes a third pre-bending mechanism 41. The third pre-bending mechanism 41 is arranged behind the second pre-bending mechanism 30 and opposite to the flipping member 42. The third pre-bending mechanism 41 includes at least one third pressing member 411 arranged at a preset angle with respect to the second direction Y. At least one third pressing member 411 is arranged in one-to-one correspondence with at least one bent portion 120. Each third pressing member 411 is arranged to be movable along the first direction X. The third pressing member 411 is used to bend the corresponding second bent section 160 to form a first sub-bent section 170 and a second sub-bent section 180 with a bent connection. One end of the second sub-bent section 180 far from the first sub-bent section 170 contacts the mounting portion 110.

[0055] Specifically, in implementation, the third pre-bending mechanism 41 includes two third pressing members 411 arranged at intervals along the second direction Y. The third pressing member 411 can move along the first direction X, so as to re-bend the second bent section 160 perpendicular to the first direction X during the downward movement, forming the first sub-bent section 170 and the second sub-bent section 180 with a bent connection as Figure 3 shown, so that the second sub-bent section 180 can be perpendicular to the second direction Y and contact the mounting portion 110. Finally, an assembled portion 130 surrounded by the first bent section 150, the first sub-bent section 170, the second sub-bent section 180 and a part of the mounting portion 110 is formed. The cross-section of the assembled portion 130 is rectangular and hollow inside.

[0056] Specifically, the third pressing member 411 is a plate-like structure perpendicular to the second direction Y, and the flipping member 42 is a cuboid structure having the same shape as the internal space of the assembling portion 130. Before the bending operation of the third pressing member 411, the flipping member 42 moves along the third direction Z to the bending structure 300 under the drive of the driving motor and abuts against the mounting portion 110, the first bending section 150, and the second bending section 160. Subsequently, the third pressing member 411 moves downward to bend the second bending section 160, so that the first sub-bending section 170 and the second sub-bending section 180 are attached to the adjacent side surfaces of the flipping member 42 to form the assembling portion 130. Finally, the flipping member 42 can drive the assembling portion 130 to be flipped and bonded.

[0057] As Figure 5 shown, the forming device of the first embodiment of the present application, wherein the second pre-bending mechanism 30 further includes at least one second blocking portion 32 that is opposite to the second pressing member 31 in the second direction Y. At least one second blocking portion 32 is provided corresponding to at least one second pressing member 31 one by one. The second blocking portion 32 includes a first connecting portion 321 and a first baffle 322 that are sequentially connected in the second direction Y. The first baffle 322 is used to abut against the first bending section 150, and the first connecting portion 321 is used to separate the second bending section 160 from the mounting portion 110.

[0058] Specifically, during the further bending of the bending portion 120 by the second pressing member 31, the first baffle 322 can abut against a part of the bending portion 120 close to the mounting portion 110 to prevent the second pressing member 31 from pressing on the entire bending portion 120, thereby ensuring that the bending portion 120 can be bent to form the first bending section 150 and the second bending section 160 that are bent and connected. The first connecting portion 321 is disposed between the second bending section 160 and the mounting portion 110 to prevent the second bending section 160 from being attached to the mounting portion 110 under the pressing of the second pressing member 31 and unable to perform the next bending.

[0059] Specifically, the forming device further has a mounting bracket that is higher than the second pre-bending mechanism 30 in the first direction X, and in the third direction Z, the mounting bracket is disposed opposite to the second pre-bending mechanism 30. The second blocking portion 32 can be suspended and connected to the mounting bracket, thereby preventing the bending structure 300 from being blocked by the second blocking portion 32 during the transmission process and affecting the subsequent bending operation.

[0060] As Figure 2As shown, the forming device of the first embodiment of the present application. The forming device further includes a fixing member 50, and the fixing member 50 is arranged between the second pre-bending mechanism 30 and the forming assembly 40. The fixing member 50 includes at least one second baffle 51, and at least one second baffle 51 is arranged in one-to-one correspondence with at least one bending portion 120. The plane where the second baffle 51 is located is perpendicular to the first direction X, and the fixing member 50 is movably arranged along the first direction X.

[0061] During specific implementation, during the process of transporting the bending structure 300 from the second pre-bending mechanism 30 to the forming assembly 40, the second bending section 160 is parallel to the installation portion 110 as a whole. The plane where the second baffle 51 of the fixing member 50 is located is perpendicular to the first direction X, and can abut against the top surface of the second bending section 160, avoiding the second bending section 160 from rebounding during the transportation state and affecting the further bending at the third pre-bending mechanism 41 and the forming assembly 40.

[0062] The forming device of the second embodiment of the present application. The pre-bending assembly 200 includes a fourth pre-bending mechanism and a fifth pre-bending mechanism arranged in sequence, and the fourth pre-bending mechanism and the fifth pre-bending mechanism can perform at most two bends on the to-be-formed structure 100.

[0063] During specific implementation, the pre-bending assembly 200 of the second embodiment of the present application includes a fourth pre-bending mechanism and a fifth pre-bending mechanism arranged in sequence, which can perform at most two bends on the to-be-formed structure 100 in sequence, so that the bending portion 120 and a part of the installation portion 110 after bending and forming can form a prismatic structure with at most three edges or a columnar structure with an arc-shaped surface, which can buffer different-shaped items, and the columnar structure with an arc-shaped surface does not have protruding sharp corners, which can play a better buffering effect on the items and avoid the assembly portion 130 from damaging the items by itself.

[0064] Specifically, the radian of the arc-shaped surface of the columnar structure with an arc-shaped surface is greater than 0 degrees and less than or equal to 180 degrees. When the radian of the arc-shaped surface is 180 degrees, the pre-bending assembly 200 bends the to-be-formed structure 100 to form the installation portion 110 and the bending portion 120, and the bending portion 120 is an arc-shaped surface structure in a semicircle as a whole. The installation portion 110 and the semicircular bending portion 120 jointly enclose a columnar structure; when the radian of the arc-shaped surface is greater than or equal to 0 degrees and less than or equal to 180 degrees, the pre-bending assembly 200 bends the to-be-formed structure 100 to form the installation portion 110 and the bending portion 120, and bends the bending portion 120 to form a first bending section 150 and a second bending section 160. The first bending section 150 is a planar structure and is bent and connected to the installation portion 110. The second bending section 160 is an arc-shaped surface structure, one end is bent and connected to the first bending section 150, and the other end contacts the installation portion 110 to enclose a columnar structure.

[0065] Such as Figure 6and Figure 7 As shown in Figure 7 , for the forming device according to an embodiment of the present application, the bonding assembly 20 includes a first bonding member 21 and a second bonding member 22 that are spaced apart in the third direction Z. Both the first bonding member 21 and the second bonding member 22 are movably arranged along the first direction X and the third direction Z. The first bonding member 21 is used to apply hot melt adhesive on the surface of the mounting portion 110, and the second bonding member 22 is used to apply white glue on the surface of the mounting portion 110.

[0066] During specific implementation, the first bonding member 21 and the second bonding member 22 sequentially apply hot melt adhesive and white glue on the surface of the mounting portion 110 to form a bonding portion 140. The hot melt adhesive has high bonding strength, while the white glue has a fast curing speed. When the two adhesives are used for bonding simultaneously, the bonding portion 140 can adapt to various environments, ensuring the bonding strength in different environments and preventing the cardboard structure after forming from falling apart.

[0067] Specifically, the bonding assembly 20 is disposed between the second pre-folding mechanism 30 and the first pre-folding mechanism 10. After the first pre-folding mechanism 10 presses the mounting portion 110 to be vertically connected to the bending portion 120, the bonding assembly 20 applies an adhesive on the surface of the mounting portion 110, avoiding the influence of the movement of the bonding assembly 20 after the bending portion 120 is bent again, and enabling the bonding assembly 20 to smoothly apply the adhesive on the surface of the mounting portion 110.

[0068] As Figure 8 As shown in Figure 8 , for the forming device according to an embodiment of the present application, it further includes: a defoaming assembly 70, including at least one defoaming plate 71. The plane where the defoaming plate 71 is located is perpendicular to the first direction X. At least one defoaming plate 71 is arranged in one-to-one correspondence with at least one assembling portion 130. The defoaming plate 71 is movably arranged along the third direction Z and is used to insert into the assembling portion 130 and press on the bonding portion between the assembling portion 130 and the bonding portion 140.

[0069] During specific implementation, the defoaming plate 71 is a plate-like structure perpendicular to the first direction X. During the process of its moving along the third direction Z towards and pressing on the bonding portion between the assembling portion 130 and the bonding portion 140, the gap between the assembling portion 130 and the bonding portion 140 becomes smaller, the bonding between the assembling portion 130 and the bonding portion 140 by the adhesive becomes tighter, and the air bubbles in the adhesive will be discharged from the adhesive under the pressure of the defoaming plate 71, making the adhesive have a better bonding effect.

[0070] Specifically, the defoaming plate 71 is driven by a driving cylinder connected thereto, so that it can move along the third direction Z on the guide rail.

[0071] As Figure 10As shown in the figure, the forming device of the embodiment of the present application further includes: a transfer assembly 60, the transfer assembly 60 includes a transfer structure 61 and a plurality of workstations arranged at intervals in sequence. The first pre-folding mechanism 10, the bonding assembly 20, the second pre-folding mechanism 30, the third pre-folding mechanism 41 and the forming assembly 40 are respectively arranged at different workstations. The transfer structure 61 is used to move the to-be-formed structure 100 between different workstations.

[0072] Specifically, the transfer structure 61 is composed of two continuously movable guide rails. Driven by the guide rails, the to-be-formed structure 100 can be moved to different workstations to perform bending and flipping operations in sequence, and finally complete the overall forming.

[0073] As Figure 9 shown in the figure, the forming device of the embodiment of the present application further includes: a loading assembly 80, including a suction cup structure 81, a loading guide rail 82 and a plurality of storage members 83. The plurality of storage members 83 are arranged at intervals and movably along the third direction Z. The suction cup structure 81 is opposite in position to one of the storage members 83 in the third direction Z. The loading guide rail 82 extends along the second direction Y. The suction cup structure 81 is movably arranged on the loading guide rail 82. The suction cup structure 81 is used to transfer the to-be-formed structure 100 in the storage member 83 to the pre-folding assembly 200.

[0074] Specifically, the suction cup structure 81 of the loading assembly 80 can suck the to-be-formed structure 100 stored in the storage member 83, move along the loading guide rail 82 to the pre-folding assembly 200 after sucking, and place the to-be-formed structure 100 on the workstation where the first pre-folding mechanism 10 is located, so that the first pre-folding mechanism 10 can start to bend the to-be-formed structure 100, completing the automatic loading of the loading assembly 80.

[0075] Specifically, the plurality of storage members 83 are all arranged on the same support plate. The support plate is slidably arranged on a guide rail extending along the third direction Z. By moving the support plate along the third direction Z, the storage member 83 storing the to-be-formed structure 100 can be moved to the position where the suction cup structure 81 is located, so that the suction cup structure 81 can suck and transfer the to-be-formed structure 100, and the empty storage member 83 can be moved to a position where it will not interfere with the suction cup structure 81 for filling the to-be-formed structure 100, realizing the free switching effect of the storage member 83.

[0076] As Figure 10As shown in the figure, the molding equipment of the embodiment of the present application further includes: a blanking assembly 90, which includes a push plate structure 91, a blanking guide rail 92, and a conveyor belt structure 93. The conveyor belt structure 93 is sequentially connected to the defoaming assembly 70 and the molding assembly 40 along the second direction Y. Both the blanking guide rail 92 and the conveyor belt structure 93 extend along the second direction Y. The push plate structure 91 is movably arranged on the blanking guide rail 92 and is used to push the molding structure 400 at the molding assembly 40 along the second direction Y to the defoaming assembly 70 and the conveyor belt structure 93.

[0077] During specific implementation, the push plate structure 91 can move along the extension direction of the blanking guide rail 92, so as to push the molding structure 400 along the second direction Y, enabling the molding structure 400 to reach the defoaming assembly 70 from the molding assembly 40 for defoaming operation, and finally reach the conveyor belt structure 93 for conveying, completing the work of automatic blanking.
