Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging boxes, in particular to a box folding assembly and a folding packaging box. BACKGROUND

[0002] With the rapid development of household appliance manufacturing industry, the packaging and protection technology of parts and components is increasingly valued. At present, when irregular-shaped or high-surface-precision materials such as cross-flow fan blades, motors and filter cartridges of water purifiers are shipped in multiple pieces, a protection scheme of combining a packaging box with a knife card assembly is generally adopted. Specifically, the existing technology mainly relies on a corrugated paper box as an outer packaging container, and an internal knife card partition assembly formed by inserting multiple layers of paperboard longitudinally and transversely is configured, so as to realize the isolation, positioning and buffer protection of the materials in the box by building independent compartments.

[0003] However, this traditional packaging mode has the following significant defects: Firstly, the packing operation process is tedious and inefficient. The operator needs to fold the flat packaging box blank into a box and seal it in advance, then separately assemble the partition assembly by inserting the knife card paperboard, and finally place the knife card assembly into the box before implementing the packing into the box. The process chain is long and synchronous operation cannot be achieved.

[0004] Secondly, the material management is poor. The packaging box and the knife card are usually purchased separately by different suppliers, and after being stored in the warehouse, they need to be matched and sorted according to the material code. The packing personnel must spend extra time to find the corresponding box type and knife card, which is prone to misplacement and misuse, resulting in high warehouse management cost and low response efficiency.

[0005] Thirdly, the production cost of the knife card is high. Each specification of the knife card needs to be customized with a special die-cutting die, which has a long development cycle and high cost. Moreover, the production of the knife card needs to go through multiple processes such as die-cutting, indentation and waste removal, which is complex and not conducive to cost control and rapid changeover. The above problems seriously restrict the optimization of packaging efficiency and cost of household appliance manufacturing enterprises under the small-batch and multi-specification production mode.

[0025] The present application provides a box folding assembly and a folding packaging box which improve processing efficiency and packing efficiency.

[0026] The following will be described in combination with Figures 1-10 The technical solutions provided by the present application are described in more detail.

[0027] The application provides a box folding assembly 100, which comprises: a first main side plate 110, which is provided with a first upper main rocker cover 130 and a first lower main rocker cover 140 on the upper and lower sides respectively; a first auxiliary side plate 120, which is foldably connected to the left side of the first main side plate 110, and is provided with a first upper side rocker cover 150 and a first lower side rocker cover 160; at least one extension plate body 170, which is foldably connected to the right side of the first main side plate 110, and can be folded to be parallel to the first main side plate 110 in the direction of the first auxiliary side plate 120.

[0028] The box folding assembly 100 provided by the application is used for folding into a part of a packaging box, and comprises a first main side plate 110, a first auxiliary side plate 120 and at least one extension plate body 170, the first main side plate 110 is provided with a first upper main rocker cover 130 and a first lower main rocker cover 140 on the upper and lower sides respectively, the first auxiliary side plate 120 is foldably connected to the left side of the first main side plate 110, and is provided with a first upper side rocker cover 150 and a first lower side rocker cover 160, the first main side plate 110 and the first auxiliary side plate 120 are foldably connected, and the first upper main rocker cover 130, the first lower main rocker cover 140, the first upper side rocker cover 150 and the first lower side rocker cover 160 can be folded to form a part of a box structure, the extension plate body 170 is foldably connected to the right side of the first main side plate 110, and can be folded to be parallel to the first main side plate 110 in the direction of the first auxiliary side plate 120, so that a partition is formed in the box structure, and the box structure is divided into at least two cells, the box folding assembly 100 is simple to form, does not need secondary assembly of the partition and assembly with the packaging box, the packaging efficiency is greatly improved, the packaging material processing flow is simplified, only one die cutting process is needed to realize the material forming process of the carton and the partition, and the packaging material production and processing and the packaging flow are obviously improved.

[0029] It can be understood that a conventional packaging box basic structure is formed by alternately connecting two first main side plates 110 and two first auxiliary side plates 120 through score lines, and the four side plates are sequentially connected end to end to form a rectangular cylinder, wherein the first main side plate 110 usually serves as a long side of the box, the first auxiliary side plate 120 serves as a short side, and two pairs of the side plates are arranged opposite to each other to form a stable enclosed space. The closing system of the box type adopts a symmetrical design of upper and lower rocker covers, and each end face is provided with a foldable rocker cover, including a first upper main rocker cover 130 and a first lower main rocker cover 140 connected to the upper and lower edges of the two first main side plates 110 respectively, and a first upper side rocker cover 150 and a first lower side rocker cover 160 connected to the upper and lower edges of the two first auxiliary side plates 120.

[0030] In the packaging operation, the operator first folds the four side panels along the score lines to form a box profile, and then folds the first lower main flap 140 and the first lower side flap 160 of the bottom surface inward in turn, and forms a load-bearing bottom plate through tape sealing or a box nailing machine.

[0031] This kind of structure design has the advantages of simple forming process, high material utilization rate and suitable for high-speed automatic production, and only one die-cutting paperboard is needed to complete the box manufacturing, but its limitation is that the internal space is a single cavity, lacks partitioning function, and therefore when packaging multiple household appliance parts, it must be matched with a knife card lining to avoid material collision damage, which directly leads to problems such as complex packaging material supporting management, scattered and inefficient packing process.

[0032] By providing the extension plate body 170 on the first main side plate 110, the extension plate body 170 can be folded inward when the two first main side plates 110 and the two first auxiliary side plates 120 are enclosed to form a box structure, thereby forming a partition plate in the box structure and dividing the box structure into at least two loading spaces, so that at least two loading spaces can be completed by folding.

[0033] In some embodiments of the present application, the extension plate body 170 includes a foldable transverse partition plate 171 and a connecting plate 172, the transverse partition plate 171 is connected to the first main side plate 110 through the connecting plate 172, so that the transverse partition plate 171 can be folded to the first auxiliary side plate 120 through the connecting plate 172 to be parallel to the first auxiliary side plate 120. When the extension plate body 170 is provided in at least two groups, the transverse partition plate 171 and the connecting plate 172 of the adjacent two extension plate bodies 170 are connected.

[0034] In some embodiments of the present application, the extension plate body 170 includes a foldable transverse partition plate 171 and a connecting plate 172, the transverse partition plate 171 is connected to the first main side plate 110 through the connecting plate 172, and the connecting plate 172 is folded to the inside of the box structure and attached to the inner wall of the box structure, so that the transverse partition plate 171 is parallel to the first main side plate 110, so as to divide the box structure into two loading spaces.

[0035] When the extension plate body 170 is provided in at least two groups, the transverse partition plate 171 and the connecting plate 172 of the adjacent two extension plate bodies 170 are connected, so that at least two groups of the transverse partition plate 171 are folded to be parallel to the first main side plate 110, thereby dividing the box structure into at least three loading spaces.

[0036] It should be noted that the extension plate body 170 adopts a two-stage folding structure design, and the transverse partition plate 171 and the connecting plate 172 are foldably connected through a score line, wherein the other side of the connecting plate 172 is fixedly connected with the inner side surface of the first main side plate 110, forming a cantilevered extension structure. This connection relationship ensures that the transverse partition plate 171 can be folded by 180 degrees along the preset score line through the connecting plate 172 as a transition arm in the direction of the first auxiliary side plate 120, and finally folded to a vertical posture parallel to the first main side plate 110, thereby constructing a transverse partition surface inside the box. The key of this design lies in the "hinged bridge" function of the connecting plate 172, which not only realizes the structural association of the transverse partition plate 171 and the main side plate, but also provides sufficient folding freedom, so that the transverse partition plate 171 is in a planar spreading state during storage and transportation, and can be accurately positioned to the working position during packaging.

[0037] When the length of the box is relatively long or multiple compartments need to be set, at least two groups of the extension plate body 170 can be arranged along the longitudinal direction of the first main side plate 110, forming an array arrangement. At this time, the transverse partition plate 171 of the extension plate body 170 of the previous group and the connecting plate 172 of the extension plate body 170 of the next group are directly connected through a score line in an interlaced connection manner, forming an alternating series structure of "horizontal-connection-horizontal-connection". This layout significantly optimizes the material utilization rate, and the entire extension plate body 170 array can be continuously formed from a die-cut paperboard without additional gluing or nailing processes. When folded, the transverse partition plates 171 and the connecting plates 172 of each group are folded together to form an array of transverse partition plates 171 arranged in parallel at equal intervals, which can quickly construct a matrix-type partition grid in the box after being accurately inserted into the slotted groove 190 of the first longitudinal partition plate 180. This structure not only realizes the synchronous folding formation of multiple partition plates, greatly improving the packaging efficiency, but also enhances the overall rigidity through the continuous connection between the plate bodies, avoiding the shaking or loosening problem of single partition plate under stress, and is particularly suitable for packaging scenes of household appliance parts such as cross-flow fan blades and motors which need to be subdivided into multiple independent protection units.

[0038] In some embodiments of the present application, a first longitudinal partition plate 180 is arranged on the first upper side rocker cover 150 and / or the first lower side rocker cover 160, and a slotted groove 190 is arranged on the first longitudinal partition plate 180, which corresponds to the folded position of the transverse partition plate 171.

[0039] In some embodiments of the present application, the first longitudinal partition 180 is arranged on the first upper side flap 150 and / or the first lower side flap 160, and can be folded inward to form the first longitudinal partition 180 after the first upper side flap 150 and / or the first lower side flap 160 is folded, so as to form a plurality of loading spaces staggered by the transverse partition 171 and the first longitudinal partition 180 in the box structure. The slotted groove 190 can ensure that the transverse partition 171 and the first longitudinal partition 180 are staggered.

[0040] It can be understood that the foldable first longitudinal partition 180 is directly formed on the plate body of the first upper side flap 150 and / or the first lower side flap 160 by die cutting and indentation process, and the first longitudinal partition 180 and the flap are kept with a folding indentation line, so that the first longitudinal partition 180 can be flatly folded in the storage and transportation state without increasing the additional volume.

[0041] One, two or more slotted grooves 190 are accurately arranged on the plate surface of the first longitudinal partition 180, and the slotted position, slot width and depth of the slotted groove 190 are strictly corresponding to the insertion position of the transverse partition 171 after being folded, so as to form an accurate assembly reference. In actual operation, when the side plate of the packaging box is folded to form a three-dimensional box structure, the first longitudinal partition 180 is synchronously folded inward by 90 degrees and vertically suspended with the flap, at this time, the transverse partition 171 is folded and formed along the indentation line thereof, and the edge thereof is inserted into the slotted groove 190 of the first longitudinal partition 180, and a longitudinal and transverse staggered grid-shaped separation system can be quickly constructed through the mortise and tenon type interlocking structure.

[0042] This kind of structure design completely solves the mode of separating the traditional packaging box and the cutter, realizes the integrated manufacturing of the packaging box and the partition, not only greatly simplifies the packaging operation process, avoids the sorting and assembling links of the split cutter, but also significantly reduces the number of material codes and the difficulty of warehouse management, and simultaneously, the cutter die cutting die does not need to be separately opened and manufactured, so that the tooling cost and the production preparation period are effectively saved.

[0043] It should be noted that the first longitudinal partition 180 can be arranged on the first upper side flap 150, or arranged on the first lower side flap 160, or arranged on both the first upper side flap 150 and the first lower side flap 160.

[0044] In some embodiments of the present application, the first longitudinal partition 180 is arranged with two or more, and the two or more first longitudinal partitions 180 are connected through the partition plate.

[0045] In some embodiments of the present application, the first longitudinal partition 180 is provided with two or more, and the two or more first longitudinal partitions 180 are connected by a partition plate, so as to divide the box structure into more loading spaces.

[0046] It can be understood that when the box size is large or needs to be subdivided into more cells, two or more first longitudinal partitions 180 are integrally formed on the first upper rocker cover 150 or the first lower rocker cover 160 by a die-cutting process, and each first longitudinal partition 180 is parallel to each other and has an equal spacing, and together forms a main partition frame.

[0047] In order to ensure the synchronization and structural stability of each first longitudinal partition 180 during folding, the adjacent first longitudinal partitions 180 are transversely connected by a partition plate, which is also integrally formed with the first longitudinal partition 180 by paperboard die-cutting, and a pressure mark transition line is reserved between the two, forming a planar array structure similar to a "lattice". During the storage and transportation stage, the entire partition array is laid on the rocker cover surface, without increasing the additional volume and transportation cost; during the packaging operation, the operator folds the rocker cover inward, and the first longitudinal partition 180 and the partition plate are erected synchronously, and the partition plate forms a horizontal support between the adjacent first longitudinal partitions 180, significantly enhancing the bending rigidity and compressive strength of the overall structure, effectively preventing the first longitudinal partition 180 from tilting or collapsing under stress. At this time, the transverse partition 171 is inserted into the corresponding slotted groove 190 of each first longitudinal partition 180 in sequence, and a stable and reliable three-dimensional grid partition system can be quickly built. Such a connected design not only simplifies the assembly process and avoids the tedious operation of aligning and inserting the split knife, but also greatly improves the overall strength and durability of the inner lining structure through the truss-like connection of the partition plate, and is particularly suitable for packaging and protecting household appliance parts such as cross-flow fan blades and motors, which have a large mass and need to be stacked in multiple layers. Under the premise of ensuring the protection performance, the material utilization rate and production efficiency are optimized.

[0048] In some embodiments of the present application, the first upper rocker cover 150 and the first lower rocker cover 160 are the same size or different sizes.

[0049] In some embodiments of the present application, when the first upper rocker cover 150 and the first lower rocker cover 160 are different in size, the first longitudinal partitions 180 on the first upper rocker cover 150 and the first lower rocker cover 160 can form two partitions, dividing the box structure into more cells.

[0050] In some embodiments of the present application, the transverse partition 171 is provided with an adhesive plate 173 away from the connecting plate 172.

[0051] In some embodiments of the present application, the transverse partition plate 171 is connected to the inner wall of the box structure by the adhesive plate 173, and the adhesive plate 173 is used for positioning and bonding.

[0052] In some embodiments of the present application, the first auxiliary side plate 120 is provided with an adhesive position.

[0053] In some embodiments of the present application, the first auxiliary side plate 120 is provided with an adhesive position, and the adhesive position is used for bonding and fixing the adhesive plate 173 on the transverse partition plate.

[0054] In some embodiments of the present application, the connecting plate 172 is provided with an adhesive position, and the adhesive position is used for bonding the inner wall of the box.

[0055] The present application also provides a folding packaging box comprising the box folding assembly 100 as described above.

[0056] The present application provides a folding packaging box comprising the box folding assembly 100 as described above, which comprises a first main side plate 110, a first auxiliary side plate 120, and at least one extension plate body 170. The first main side plate 110 is provided with a first upper main rocker cover 130 and a first lower main rocker cover 140 on the upper and lower sides, respectively.
