Description

Technical Field

[0001] This application relates to the field of cardboard box technology, and more specifically to an irregularly shaped cardboard box and its processing method and equipment. Background Technology

[0002] Cardboard boxes are commonly used to wrap items to protect them and facilitate storage or transportation.

[0003] like Figure 1 As shown, a hot and cold water faucet 90 includes a housing 91. One end of the housing 91 has two extension pipes 92, one for connecting to a hot water pipe and the other for connecting to a cold water pipe. The other end of the housing 91 has an outlet pipe. The two extension pipes 92 are interconnected and connected to the outlet pipe. A valve 93 is rotatably installed at the connection between the extension pipe 92 and the outlet pipe. When the valve 93 is rotated, one extension pipe 92 opens and the other extension pipe 92 closes. Currently, when packaging and transporting the hot and cold water faucet 90, it is usually placed in a rectangular or cubic cardboard box and sealed before transport. However, it is evident that when the hot and cold water faucet 90 is placed in the cardboard box, there is a lot of empty space inside, resulting in low space utilization. When using containers for large-scale transportation, a large amount of unused space within a container leads to high transportation costs.

[0004] In addition, existing methods and equipment for processing cartons often involve folding the cartons into cardboard shapes before stapled assembly. After stapled assembly, the folded cartons are manually propped up into a three-dimensional shape before sealing the bottom, placing the product inside, and sealing the top. The advantage of this method is that folded cardboard cartons are easy to staple automatically. However, the step of propping up the cartons into a three-dimensional shape after stapled assembly is difficult to replace mechanically, and it still has certain limitations in large-scale, high-intensity production.

[0005] Therefore, there is a need for a space-efficient and easily transportable irregularly shaped cardboard box, as well as a processing method and equipment for processing irregularly shaped cardboard boxes that facilitates automated production and is suitable for mass production and high-intensity manufacturing.

[0048] Application Overview

[0049] Existing cardboard boxes have low space utilization when packing products of specific shapes. When using containers for large-volume transportation, there is a lot of unused space in a container, resulting in high transportation costs. In the existing cardboard box processing methods and equipment, it is difficult to mechanically replace the step of supporting the cardboard box into a three-dimensional shape after nailing. Therefore, there are still certain limitations in large-scale, high-intensity production.

[0050] Based on the above-mentioned technical problems, this application proposes an irregularly shaped cardboard box, a processing method and equipment thereof, wherein the irregularly shaped cardboard box, the processing method and equipment thereof have a simple structure, do not involve complex manufacturing processes and expensive materials, and have high economic efficiency. At the same time, for manufacturers, the irregularly shaped cardboard box, the processing method and equipment thereof provided by this application are easy to produce and have low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0051] Illustrative irregular-shaped cardboard boxes and their processing methods and equipment,

[0052] refer to Figures 2 to 5 According to a preferred embodiment of the present invention, an irregularly shaped cardboard box is used for packaging such as... Figure 1 The hot and cold water faucet 90 shown includes a housing 91 with an oblong horizontal cross-section. One end of the housing 91 has two extending pipes 92, such as... Figure 2 As shown, the irregularly shaped cardboard box includes a cardboard box body 10. The top surface of the cardboard box body 10 has two protrusions 101 and two bonding portions 102. The cross-sectional shape of each of the protrusions 101 is square. The two protrusions 101 are arranged opposite each other and one side overlaps. Each bonding portion 102 is located between the two protrusions 101 and is arranged opposite each other. The cross-sectional shape of each bonding portion 102 is an isosceles triangle, and the sum of the cross-sectional areas of the isosceles triangles of the two bonding portions 102 is equal to the sum of the cross-sectional areas of the square of one of the protrusions 101.

[0053] It should be noted that the extension pipes 92 correspond one-to-one with the protrusions 101. The protrusions 101 provide space for the extension pipes 92. When the hot and cold water faucets 90 are placed inside the carton body 10, the extension pipes 92 extend into the corresponding internal spaces formed by the protrusions 101. It should also be noted that when transporting the irregularly shaped carton, refer to... Figure 3 Multiple irregularly shaped cardboard boxes are arranged in a honeycomb pattern as shown in the figure, forming a first layer. It is evident that the fitting portions 102 of two adjacent cardboard box bodies 10 are joined to form a square cavity 103. The protrusions 101 of the irregularly shaped cardboard boxes placed in the second layer can precisely extend into this square cavity. Assuming the first layer of irregularly shaped cardboard boxes is arranged vertically, then... Figure 4 As shown, the second layer of irregularly shaped cardboard boxes placed above the first layer are arranged horizontally, while the third layer is arranged in the same direction as the first layer, and the fourth layer is arranged in the same direction as the second layer. That is, the irregularly shaped cardboard boxes are arranged in an alternating horizontal and vertical manner in the height direction, which will not be elaborated further. It is evident that, compared to the prior art where rectangular cardboard boxes are stacked vertically, this embodiment fully utilizes the structural features of the two extension pipes 92 of the hot and cold water faucet 90, making use of the space between the two extension pipes 92. When the protrusion 101 of the second layer of irregularly shaped cardboard boxes is embedded in the square cavity formed by splicing the first layer of irregularly shaped cardboard boxes, the overall height of the two layers of irregularly shaped cardboard boxes is lower than the overall height of the two layers of rectangular cardboard boxes, resulting in higher space utilization. More products can be loaded into the same space of the transport container, which helps to reduce transportation costs and achieve the advantage of convenient transportation.

[0054] Specifically, to form the carton body 10, the unfolded view of the carton body 10 is as follows: Figure 5As shown, the carton body 10 includes two side panel assemblies 103. Each side panel assembly 103 includes a first side panel 1031, a second side panel 1032, and a third side panel 1033. The first side panel 1031, the second side panel 1032, and the third side panel 1033 are connected sequentially. The first side panel 1031 in one side panel assembly 103 is connected to the third side panel 1033 in another side panel assembly 103. Each first side panel 1031 has a bottom surface 1034 and a facing assembly at both ends. (Not shown in the figure) The veneer assembly includes a first top surface 1035 and two fourth side surfaces 1036. The two fourth side surfaces 1036 are located on both sides of the first top surface 1035. Each fourth side surface 1036 has a slot 10361. The end of the second side surface 1032 facing away from the bottom surface 1034 has a second top surface 1037. The second top surface 1037 has two oppositely arranged insertion ends 10371. One side of the first side surface 1031 in the side surface assembly 103 has a nailing part 1038.

[0055] It should be noted that after the stapled part 1038 is stapled with the other third side 1033, a hexagon that runs vertically through it is formed. That is, the first side 1031, the second side 1032, and the third side 1033 are all sides of the carton body 10. By making the two bottom surfaces 1034 fit together, the bottom surface of the hexagon is closed. That is, the two bottom surfaces 1034 constitute the bottom surface of the carton body 10. The first top surface 1035 is the top surface of the protrusion 101, and the two fourth side surfaces 1036 are all sides of the protrusion 101. By making the insertion end 10371 insert into the corresponding slot 10361, the top surface of the hexagon is closed.

[0056] Figure 6 The illustration shows a preferred embodiment of a method for processing an irregularly shaped cardboard box according to the present invention. The method is used to add the irregularly shaped cardboard box. Specifically:

[0057] S1: Die-cut cardboard;

[0058] A cardboard die-cutting machine is used to die-cut cardboard into a predetermined shape. The die-cut cardboard is then... Figure 5 The cardboard box body 10 shown is in an unfolded state;

[0059] S2: Cardboard splicing and stapling;

[0060] For the unfolded carton body 10, the first side 1031 in one side assembly 103 of the carton body 10 is brought into contact and connected with the third side 1033 in another side assembly 103 by the stapler, forming a three-dimensional carton with neither the top nor the bottom closed.

[0061] More specifically, the die-cut cardboard from step S1 is fed into the stapling equipment via the feeding device. The unfolded die-cut cardboard is then bent at a predetermined angle and assembled into a three-dimensional shape via the bending device in the stapling equipment. This three-dimensional shape is formed by the stapling part 1038 in one side assembly 103 of the carton body 10 contacting the third side 1033 in the other side assembly 103, forming a hexagonal three-dimensional carton with an open top and bottom surface. The stapling part 1038 is then stapled to the third side 1033 via the stapling device in the stapling equipment. It should be noted that pre-assembling the cardboard is not only for easy stapling but also to obtain a three-dimensional carton directly after stapling, so that subsequent processes can directly seal the edges and pack the products. Secondly, the purpose of pre-assembling the cardboard is that this process of assembling flat cardboard into a three-dimensional carton is easy to achieve mechanically, which helps to automate the entire carton processing process and has application potential in mass production with high intensity.

[0062] S3: Package;

[0063] For a three-dimensional cardboard box that is not closed on the top and bottom surfaces, the two bottom surfaces 1034 of the cardboard box body 10 are glued together with tape, and the insertion end 10371 is inserted into the corresponding slot 10361 to obtain a sealed cardboard box body 10.

[0064] It should be noted that in the actual production process, after sealing the bottom surface of the three-dimensional cardboard box with tape, the product is first placed into the irregularly shaped cardboard box, and then the insertion end 10371 is inserted into the corresponding slot 10361 to achieve product packaging; in addition, the implementation method of bonding the two bottom surfaces 1034 of the cardboard box body 10 with tape includes, but is not limited to, using a carton sealing machine to bond the two bottom surfaces 1034; and the implementation method of placing the product into the irregularly shaped cardboard box includes, but is not limited to, using a robotic arm to place the product into the corresponding irregularly shaped cardboard box.

[0065] Figures 7 to 13 The illustration shows a processing device for irregularly shaped cartons according to a preferred embodiment of the present invention. The processing device for irregularly shaped cartons is used to complete step S2 of the above-mentioned processing method for irregularly shaped cartons, and includes a frame 20, a contour table 30, a pressing device 40, a bending assembly 50, and a nailing device 60.

[0066] Specifically, such as Figure 8As shown, the contouring table 30 is fixedly connected to the frame 20, and the fixed connection method includes but is not limited to welding. The cross-sectional shape of the contouring table 30 is hexagonal. The hexagonal cross-section of the contouring table 30 is only proportionally scaled to the hexagonal cross-section of the carton body 10. Each interior angle of the hexagonal cross-section of the contouring table 30 is the same as each interior angle of the hexagonal cross-section of the carton body 10. Further, the contouring table 30 has a stapling surface 301 and a pressing surface 302. In the height direction of the contouring table 30, the stapling surface 301 and the pressing surface 302 are adjacent to each other and arranged perpendicularly.

[0067] It should be noted that after the die-cut cardboard in its unfolded form is fed into the equipment for the irregularly shaped carton, the side assembly 103 with the stapled part 1038 is attached to the pressing surface 302, and the stapled part 1038 is located on the side of the pressing surface 302 close to the stapled surface 301.

[0068] In addition, such as Figure 8 and Figure 9 As shown, the pressing device 40 includes a first pressing member 401, which is movably mounted on the frame 20. The first side 1031 connected to the nailing part 1038 is located between the pressing surface 302 and the first pressing member 401. The first pressing member 401 presses the first side 1031 connected to the nailing part 1038 onto the pressing surface 302, thus preparing for the bending assembly 50.

[0069] In addition, such as Figure 8 As shown, the bending assembly 50 includes three bending devices (not shown in the figure). All three bending devices are located outside the contouring table 30 and arranged in a ring. Each bending device includes a bending element 5011. The bending element 5011 has a contouring surface (not shown in the figure). The contouring surface is directly opposite the side of the contouring table 30, and the included angle of each surface on the contouring surface is the same as the included angle of the side corresponding to the side of the contouring table 30. The bending element 5011 is movably mounted on the frame 20, and the contouring surface is close to or separate from the side of the contouring table 30.

[0070] In addition, the nailing device 60 is movably mounted on the frame 20 and close to or away from the nailing surface 301. The nailing device 60 includes a nailing machine (not shown in the figure), which nails the die-cut cardboard into three-dimensional shapes. Since the nailing machine technology is mature and widely used in the market, the specific structure of the nailing machine will not be described in detail here. The nailing machine includes, but is not limited to, the nailing machine disclosed in the patent document (CN201911394568.5).

[0071] The processing equipment for the aforementioned irregularly shaped cardboard boxes will now be briefly described: For example... Figure 8 As shown, when the die-cut cardboard is fed into the processing equipment for the irregularly shaped carton, one end of the die-cut cardboard with the stapled portion 1038 is pressed against the pressing surface 302 by the pressing device 40, and the die-cut cardboard is not bent. It should be emphasized that at this time, one of the bending devices is located on the side of the die-cut cardboard close to the pressing device 40. For ease of description, it is assumed that this bending device is the first bending assembly 501, and the other two bending devices are located on the side of the die-cut cardboard away from the pressing device 40. It is assumed that these two bending devices are the second bending assembly 502 and the third bending assembly 503, wherein the third bending assembly 503 is located between the second bending assembly 502 and the stapled device 60, and to avoid interference with the movement of the second bending assembly 502 during the cardboard flipping process, the second bending assembly 502 is liftable. The die-cut cardboard is mounted on the frame 20. When the pressing device 40 presses the die-cut cardboard, the first bending assembly 501 operates. At a certain moment, the bending element 5011 in the first bending assembly 501 contacts the end of the die-cut cardboard away from the pressing device 40, and drives the end of the die-cut cardboard away from the pressing device 40 to rotate by a predetermined angle until the first side 1031 and the second side 1032 of the side assembly 103 with the stapled part 1038 in the die-cut cardboard are completely in contact with the side of the contour table 30, while the third side 1033 of this side assembly 103 is partially in contact with the contour table 30, and the other side assembly 103 is still not in contact with the side of the contour table 30 and is in a suspended state. At this time, the first bending assembly 501 stops operating. Figure 10As shown; subsequently, the second bending assembly 502 actuates and contacts the carton body 10 at a certain moment until the third side 1033 of the side assembly 103 with the stapled portion 1038 is completely in contact with the side of the contouring table 30, and the first side 1031 of the other side assembly 103 is partially in contact with the side of the contouring table 30. At this time, only the second side 1032 and the third side 1033 of the other side assembly 103 are not in contact with the side of the contouring table 30. Then the third bending assembly 503 actuates and causes the third side 1033 to be in contact with the stapled surface 301. It should also be emphasized that when the When the pressing device 40 presses the first side 1031 with the stapled part 1038, the stapled part 1038 is also pressed by the pressing device 40 onto the stapled surface 301. When the third side 1033 in another side assembly 103 is pressed onto the stapled surface 301 by the third bending assembly 503, this third side 1033 partially overlaps with the stapled part 1038. Then the nailing device 60 approaches the stapled surface 301 and nails the stapled part 1038 and the third side 1033 together. At this time, the die-cut cardboard forms a hexagonal three-dimensional carton with both the top and bottom surfaces open, completing step S2.

[0072] Specifically, to enable the pressing device 40 to be movably mounted on the frame 20, such as... Figure 8 As shown, the pressing device 40 further includes a first linear drive device 402. The first pressing member 401 is fixedly connected to the push rod of the first linear drive device 402. The fixed connection method includes, but is not limited to, threaded connection. The first linear drive device 402 is fixedly installed on the frame 20.

[0073] Furthermore, in order to achieve the following: when the pressing device 40 presses the first side 1031 with the nailing part 1038 onto the pressing surface 302, it also presses the nailing part 1038 onto the nailing surface 301, such as... Figure 9As shown, the pressing device 40 further includes a second pressing member 403, which is movably mounted on the first pressing member 401. Specifically, the pressing device 40 also includes a second linear drive device (not shown in the figure), which is fixedly mounted on the first pressing member 401. The second pressing member 403 is fixedly connected to the push rod of the second linear drive device by a threaded connection. The movement direction of the push rod of the second linear drive device is perpendicular to the movement direction of the push rod of the first linear drive device 402. In addition, when the die-cut cardboard is fed into the device for the irregularly shaped carton, the stapled part 1038 is coplanar with the first side surface 1031, and the distance between the first pressing member 401 and the first side surface 1031 is less than the distance between the second pressing member 403 and the stapled part 1038. Therefore, when the first linear drive device 402 is activated and causes the first pressing member 401 to move closer to the pressing surface, At time 302, the second pressing member 403, while following the movement of the first pressing member 401, first contacts the stapled part 1038 and causes the stapled part 1038 to bend. It should be noted that, due to the limitation of the feeding device, the overall position of the die-cut cardboard does not shift during the process of the second pressing member 403 contacting and bending the stapled part 1038. For the sake of describing the second pressing member 403, the structure of the feeding device will not be elaborated here. When the stapled part 1038 is subjected to force and bends at a predetermined angle towards the stapled surface 301, the first pressing member 401 presses the first side 1031 against the pressing surface 302. Then the second linear drive device is activated, causing the second pressing member 403 to move closer to the stapled surface 301. At a certain moment, the stapled part 1038, which is bent under force and located between the second pressing member 403 and the stapled surface 301, is pressed against the stapled surface 301.

[0074] Furthermore, to enable the bent component 5011 to be movably mounted on the frame 20, as follows: Figure 8 As shown, each of the bending devices includes a third linear drive device 5012, which is fixedly mounted on the frame 20. The bending member 5011 is fixedly connected to the push rod of the third linear drive device 5012, and the fixed connection method includes, but is not limited to, threaded connection.

[0075] It should also be noted that during the process of the third side 1033 in another side assembly 103 being attached to the nailing surface 301, the nailing device 60 should be kept away from the nailing surface 301 to avoid interference between the third side 1033 and the nailing device 60 during the bending of the third side 1033 toward the nailing surface 301.

[0076] In view of this, such as Figure 9 and Figure 11 As shown, the nailing device 60 includes a bracket 601. The nailing machine is vertically and flexibly mounted on the bracket 601 via a linear module and moves with the bracket 601. The processing equipment for the irregularly shaped cardboard box also includes a first connecting rod 4011. The two ends of the first connecting rod 4011 are rotatably connected to the first pressing member 401 and the bracket 601, respectively. Additionally, as... Figure 8 and Figure 11 As shown, the frame 20 has a slide rail 201, and the end of the bracket 601 facing away from the first connecting rod 4011 is slidably disposed on the slide rail 201. The arrangement direction of the slide rail 201 is perpendicular to the nailing surface 301. When the first pressing member 401 moves toward the pressing surface 302, the nailing device 60 moves a predetermined distance away from the nailing surface 301.

[0077] It should be noted that when the third side 1033 in another side assembly 103 overlaps with the nailing part 1038, the nailing device 60, which was previously away from the nailing surface 301, should move a predetermined distance toward the nailing surface 301 to complete the nailing action.

[0078] In view of this, such as Figure 11 As shown, the top surface of the first pressing member 401 has a first sliding rod 4012, and the two ends of the first connecting rod 4011 respectively have a sleeve 40111 and an insert 40112. The bracket 601 has a moving hole 6011 (see reference). Figure 12 The sleeve 40111 is slidably disposed on the first slide rod 4012 in the height direction of the frame 20. The insert 40112 is slidably disposed in the moving hole 6011 in the height direction of the frame 20. The nailing device 60 also includes a backing member 6012, which is located below the insert 40112. The backing member 6012 is slidably disposed in the moving hole 6011, and one end of the backing member 6012 that is away from the insert 40112 extends out of the moving hole 6011 by a predetermined distance. Figure 9 and Figure 11As shown, a bending device near the nailing device 60 further includes a triggering component. In this invention, the triggering component is provided on the third bending component 503. The triggering component includes a second connecting rod 5031 and a third connecting rod 5032. The two ends of the second connecting rod 5031 are rotatably connected to one end of the bending member 5011 and the third connecting rod 5032, respectively. The middle sections of the second connecting rod 5031 and the third connecting rod 5032 are rotatably mounted on the frame 20. The third connecting rod 5032 is located on the side of the top abutment 6012 away from the nailing surface 301. The end of the top abutment 6012 extending out of the moving hole 6011 has an inclined surface. When it approaches the... When the bending device of the nailing device 60 is activated, the end of the third connecting rod 5032 facing away from the second connecting rod 5031 abuts against or separates from the inclined surface of the top abutment 6012. In addition, to prevent the second connecting rod 5031 from getting stuck when the third bending assembly 503 approaches the contour table 30, the end of the second connecting rod near the third bending assembly 503 has a moving groove. A round rod is welded onto the third bending assembly 503. The round rod passes through the moving groove. When the third bending assembly is activated and the distance between the round rod and the rotating part of the middle section of the second connecting rod 5031 changes, the round rod moves within the moving groove to prevent the second connecting rod from getting stuck.

[0079] In addition, such as Figure 9 and Figure 11 As shown, the bracket 601 also has a sliding groove 6014, which communicates with the moving hole 6011, such as... Figure 11 As shown, the processing equipment for the irregularly shaped cardboard box also includes a first elastic element 602, which is a spring. The two ends of the first elastic element 602 are respectively connected to the contour table 30 and the nailing device 60.

[0080] In addition, such as Figure 12 As shown, the movable hole 6011 is a through stepped hole. The top abutment 6012 includes a support portion (not shown in the figure), abutment portion 60121, and contact portion 60122. The abutment portion 60121 is located between the support portion and the contact portion 60122. The support portion abuts against the insert 40112. The abutment portion 60121 is slidably disposed in the cavity of the larger diameter of the stepped hole. The contact portion 60122 extends out of the cavity of the larger diameter of the stepped hole by a predetermined distance. The contact portion 60122 has an inclined surface. The nailing device 60 also includes a second elastic element 6013. The second elastic element 6013 is a spring. The second elastic element 6013 is sleeved on the support portion, and both ends of the second elastic element 6013 abut against the abutment portion 60121 and the bottom wall of the cavity of the larger diameter of the stepped hole, respectively.

[0081] Reference Figure 9 and Figure 11 The movement of the nailing device 60 is now described as follows: When the first linear drive device 402 is activated, causing the first pressing member 401 to move towards the pressing surface 302, the first connecting rod 4011 moves accordingly, and drives the bracket 601 of the nailing device 60 to move away from the nailing surface 301. At this time, the first elastic member 602 is stretched to a predetermined length. When the third bending assembly 503 moves towards the side of the contour table 30, the second connecting rod 5031 rotates by a predetermined angle, and drives the third connecting rod 5032 towards the top member 6012. When the contact portion rotates by a predetermined angle, and the third bending assembly 503 brings the third side surface 1033 close to the nailing surface 301, the third connecting rod 5032 contacts the inclined surface of the contact portion. As the third bending assembly 503 presses the third side surface 1033 against the nailing surface 301, the inclined surface of the contact portion receives an upward component force, causing the abutment member 6012 to move upward as a whole. At this time, the second elastic member 6013 is in a compressed state, and the insert 40112 is pushed out of the moving hole 6011 by the abutment member 6012. When the insert 40112 is pushed out... After the movable hole 6011 is reached, the first elastic element 602 returns to its pre-deformation state and drives the bracket 601 to move a predetermined distance toward the nailing surface 301. At this time, the insert 40112 moves within the slide groove 6014, and the nailing device 60 approaches the third side surface 1033 and nails the overlapping portion of the third side surface 1033 and the nailing part 1038 together. Since the bracket 601 moves a predetermined distance toward the nailing surface 301, the third connecting rod 5032 no longer contacts the inclined surface of the contact part, and the second elastic element 6013 returns to its pre-deformation state. The first pressing member 401 moves away from the pressing surface 302 and drives the first connecting rod 4011 to move. Then, the insert 40112 on the first connecting rod 4011 moves in the groove 6014 along the direction of the nailing surface 301. When the first pressing member 401 returns to the initial position, the insert 40112 on the first connecting rod 4011 falls into the moving hole 6011 again, providing conditions for nailing another die-cut cardboard for the next time.

[0082] It should also be noted that when the die-cut cardboard is fed into the processing equipment for the irregularly shaped carton, since the die-cut cardboard is arranged vertically, the first top surface 1035 and the fourth side surface 1036 may both bend downwards under gravity and overlap with the side surface assembly 103. If this overlap occurs, it will affect the stapling quality. To avoid this phenomenon, such as Figure 7 and Figure 9 As shown, the processing equipment for the irregularly shaped cardboard box also includes an inflatable component 70. The inflatable component 70 is in the form of a rod, and its material includes, but is not limited to, polyethylene plastic. The inflatable component 70 has a certain elasticity and includes several deflating zones (not shown in the figure). There are five deflating zones, which correspond to the five bends of the cardboard. Each deflating zone includes an inflation port and a deflation port. One end of the inflatable component 70 is fixedly installed on the top surface of the contouring table 30. When the bending component 5011 is in contact with the side of the contouring table 30, the bending component 5011 contacts the inflatable component 70.

[0083] It should be noted that when the die-cut cardboard is fed into the processing equipment for the irregularly shaped carton, each of the degassing zones is filled with gas. Therefore, the inflator 70 remains straight and upright. Since the inflator 70 is located on the top surface of the contour table 30, when the first top surface 1035 and the fourth side surface 1036 bend downwards under their own weight, they come into contact with the inflator 70 and do not bend further downwards. This avoids the phenomenon of the first top surface 1035 or the fourth side surface 1036 naturally overlapping with the side assembly 103 without lower support. When the first bending assembly 501 moves towards the side of the contour table 30, the corresponding two degassing zones of the inflator 70 discharge pre-gas. A predetermined amount of gas is released, and the corresponding venting zone changes from its original upright state to a partially bendable state to facilitate bending with the cardboard. The venting zones that have not yet been vented continue to support the first top surface 1035 or the fourth side surface 1036 on the side that is still in a suspended state until the side assembly 103 is completely in contact with the side of the contour table 30. At this time, each venting zone releases a predetermined amount of gas. After the cardboard is stapled in step S2, each venting zone is inflated, and the inflator 70 returns to its upright state under the gas filling and provides support for the first top surface 1035 and the fourth side surface 1036 on the next cardboard to be stapled.

[0084] Furthermore, the processing equipment for the irregularly shaped cardboard box also includes a feeding device (not shown in the figure), such as... Figure 13As shown, the feeding device includes a placement rack 80. One side of the placement rack 80 has a plurality of receiving portions 801, a plurality of receiving grooves 802, and a plurality of air holes 803. In this embodiment, each receiving portion 801 has a receiving groove 802 on one side. In addition, the top of each receiving portion 801 and the groove surface of the receiving groove 802 are provided with a plurality of air holes 803. When the die-cut cardboard is placed on the placement rack 80, each receiving groove 802 is provided with a bottom surface 1034, and the receiving portion 801 faces the second side surface 1032 and the third side surface 103. 3. A support is provided, and each of the air holes 803 draws in air and adheres the die-cut cardboard to the placement rack 80. It should be noted that since the side of the receiving groove 802 near the contour table 30 is connected to the outside, the placement rack 80 does not interfere with the movement of the cardboard when the first bending assembly 501 pushes the cardboard toward the contour table 30. In addition, as mentioned above, since the air holes 803, the receiving groove 802 and the receiving part 801 restrict the cardboard, the cardboard does not move as a whole when the second pressing member 403 contacts the nailing part 1038 first.

[0085] In addition, the processing equipment for the irregularly shaped cardboard box also includes a feeding device (not shown in the figure). The feeding device includes several robotic arms (not shown in the figure). Each robotic arm is located directly above the contour table 30. After the die-cut cardboard is stapled into shape, the robotic arm moves and removes the cardboard box fitted on the contour table 30 from above the contour table 30.

[0086] In summary, the irregularly shaped cardboard boxes and their processing methods and equipment based on the embodiments of this application have been clarified, which provide the irregularly shaped cardboard boxes with advantages such as high space utilization and convenient transportation, and provide the processing methods and equipment for irregularly shaped cardboard boxes with advantages such as facilitating automated production and being suitable for mass production and high-intensity production.
