Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a paper pallet and a paper pallet group. Background Art

[0002] At present, most of the existing pallet structures are formed incoming material pallets, which occupy a large space for logistics and transportation. To solve this problem, a paper pallet is provided in the prior art. Patent CN202022117710.6 proposes a corrugated paper composite pallet, which is formed by plugging a plug-in plate body with a plug-in attached plate and a socket plate body with a socket attached plate. The plug-in attached plate and the socket attached plate are joined to form a fork-shaped bracket, and the plug-in plate body and the socket plate body form a cargo bearing surface, which is supported by the fork-shaped bracket. The processing process saves time and labor and is easy to disassemble and transport.

[0003] However, for the above-mentioned paper pallet, since the plug-in attachment plate and the plug-in plate body are formed by folding the same corrugated cardboard, and the socket attachment plate and the socket plate body are formed by folding the same corrugated cardboard, the maximum size of the paper pallet is limited by the corrugated cardboard. When it is used for overly narrow and high carton packaging such as commercial display large-screen cartons, in order to avoid the tipping of the paper pallet structure, it is necessary to use a paper pallet larger than the carton size, but this will lead to a higher processing cost of the paper pallet and easily cause the paper pallet to occupy too much area. Utility Model Content

[0010] Furthermore, a limit plate section is formed in the cross block area between the two first clamping grooves respectively clamped with the two second clamping grooves located on the same folding plate. The limit plate section passes into the frame structure from the avoidance opening and cooperates with the inner wall of the frame structure to limit the rotation of the cross block relative to the folding plate and the movement of the cross block along the width direction of the folding plate.

[0011] According to another aspect of the utility model, a paper pallet group is provided, which includes a plurality of the above-mentioned paper pallets, and the plurality of paper pallets are arranged sequentially along the width direction of the paper pallets. When the plurality of paper pallets are in use, any two adjacent paper pallets are connected by a plurality of cross bars of the two paper pallets. When the plurality of paper pallets of the paper pallet group are connected, any one of the paper pallets is in use.

[0012] Furthermore, when multiple paper pallets of the paper pallet group are connected, multiple cross bars of the same paper pallet protrude from one side of the paper pallet along the width direction of the paper pallet, and the protruding parts of the multiple cross bars are connected one-to-one with the multiple support groups of adjacent paper pallets.

On the other hand, the length of the cross bar in this solution is greater than the width of the main board and protrudes from at least one side of the main board when in use, which increases the bottom support width of the paper pallet, which helps prevent the paper pallet from tipping over when used in overly narrow and high carton packaging such as commercial display large-screen cartons. Furthermore, the frame structure in this solution is formed by folding a folding board and supports the frame structure through the cross bar. Compared with the prior art where the maximum size of the paper pallet is limited by the folding of the corrugated cardboard, this solution can increase the bottom support width of the paper pallet by adjusting the length of the cross bar or replacing cross bars of different lengths to be suitable for cartons of different sizes, which helps to improve the applicability of the paper pallet and reduce the floor space of the paper pallet.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 7 As shown, an embodiment of the utility model provides a paper pallet 1, which includes a main board 10 and a plurality of support groups 20 arranged at intervals along the length direction of the main board 10, any one of the support groups 20 includes a detachable cross bar 21 and folding plates 22 respectively arranged on both sides of the main board 10 along the width direction of the main board 10, the folding plates 22 are composed of a plurality of sub-boards, and the paper pallet 1 has a transport state and a use state; when the paper pallet 1 is in the transport state, the cross bar 21 is disassembled, and the folding plates 22 are folded to a flat state in which the plurality of sub-boards are parallel to the main board 10; when the paper pallet 1 is in the use state, the folding plates 22 are unfolded to form a frame structure surrounded by the plurality of sub-boards, the cross bar 21 is inserted on two folding plates 22 of the same support group 20 to support the frame structure, and the two ends of the cross bar 21 along the width direction of the main board 10 protrude from the two frame structures and protrude from at least one side of the main board 10.

[0035] In this embodiment, the paper pallet 1 is retracted and released by folding, and the convenience of disassembling, assembling and transporting the paper pallet 1 is improved on the basis of ensuring the supporting effect of the paper pallet 1 on the carton 2. On the other hand, the length of the cross bar 21 in this embodiment is greater than the width of the main board and protrudes from at least one side of the main board when in use, which increases the bottom support width of the paper pallet 1, which is beneficial to prevent the paper pallet 1 from tipping over when used for packaging of too narrow and high cartons 2 such as commercial display large-screen cartons 2. Furthermore, the frame structure in this embodiment is formed by folding the folding plate 22 and the support of the frame structure is achieved by the cross bar 21. Compared with the situation in the prior art where the maximum size of the paper pallet 1 is limited by the folding of the corrugated cardboard, this embodiment can increase the bottom support width of the paper pallet 1 by adjusting the length of the cross bar 21 or replacing the cross bar 21 of different lengths, so as to be suitable for cartons 2 of different sizes, which is beneficial to improve the applicability of the paper pallet 1 and reduce the floor space of the paper pallet 1.

[0036] Specifically, the supporting groups 20 in this embodiment are 3 groups, that is, the paper pallet 1 in this embodiment includes 6 folding plates 22. Preferably, the main board 10 and the folding plates 22 in this embodiment are an integrated structure, and the two are cut and formed from the same corrugated paperboard.

[0037] like Figures 1 to 7 As shown, the projection of the folding plate 22 in the vertical direction is located on the main board 10, the folding plate 22 is folded and formed below the main board 10, the extension length of the cross bar 21 is greater than the length in the width direction of the main board 10, and when the paper pallet 1 is in use, the cross bar 21 protrudes from two frame structures at both ends along the width direction of the main board 10 and protrudes from both sides of the main board 10.

[0038] In this embodiment, multiple folding plates 22 can be foldably arranged on the outer peripheral edge of the main board 10, and such arrangement facilitates the processing of multiple folding plates 22. Further, the cross bar 21 in this embodiment protrudes from the main board 10 at both ends along the width direction of the main board 10, so as to ensure the supporting effect of the paper pallet 1 on the carton 2 as a whole on the basis of ensuring the anti-dumping reinforcement of the paper pallet 1. It can be understood that in other embodiments not shown in the figure, the cross bar 21 can also protrude only from one side of the main board 10 that is prone to dumping, so as to ensure the anti-dumping of the paper pallet 1.

[0039] like Figures 1 to 4 as well as Figure 7As shown, the cross bar 21 has a plurality of first card slots 211 spaced apart and distributed on the same side of the cross bar 21. When the paper pallet 1 is in use, any support group 20 has a plurality of second card slots 2251 distributed on the two folding plates 22 along the width direction of the main board 10. The plurality of first card slots 211 and the plurality of second card slots 2251 are carded one by one to limit the positions of the plurality of sub-plates. This arrangement facilitates the carding of the cross bar 21 while ensuring that the cross bar 21 limits the plurality of sub-plates, avoiding the situation that the sub-plates are prone to self-folding and causing deformation of the frame structure when the paper pallet 1 is in use, thereby reducing the structural strength of the paper pallet 1 itself and making it easy to tip over, thereby ensuring the structural strength of the paper pallet 1 in use and the reliability of supporting the carton 2.

[0040] In this embodiment, the plurality of sub-boards include a first sub-board 221, a second sub-board 222, a third sub-board 223 and a fourth sub-board 224 connected in sequence. When the paper pallet 1 is in use, any two connected sub-boards are perpendicular to each other. The frame structure formed by the plurality of sub-boards is rectangular. The fourth sub-board 224 is arranged on the main board 10 and fits the main board 10. The second sub-board 222 and the fourth sub-board 224 are parallel to each other. This arrangement facilitates the folding and forming of the frame structure while ensuring the supporting effect of the frame structure on the main board 10 and the carton 2 arranged on the main board 10. Specifically, as Figure 5 and Figure 6 As shown, the fourth sub-board 224 is attached to the main board 10 and the attaching position remains unchanged regardless of whether the paper pallet 1 is in the transfer state or the use state. When the paper pallet 1 is in the transfer state, the first sub-board 221 is folded to fit the fourth sub-board 224, and the second sub-board 222 is folded to fit the third sub-board 223, and the four sub-boards are parallel to the main board 10; when the paper pallet 1 is in the use state, the first sub-board 221 and the third sub-board 223 are both arranged perpendicular to the main board 10, the second sub-board 222 is located above the fourth sub-board 224 and is spaced apart from the fourth sub-board 224 in the height direction by the first sub-board 221, the third sub-board 223, and the four sub-boards are surrounded to form a frame structure.

[0041] It should be noted that the shape of the frame structure is not limited to the rectangle in this embodiment, and any other polygon that can ensure the support effect is acceptable. However, compared with a rectangle, there is a risk of increasing the width of the bottom of the paper pallet 1 or increasing the cost.

[0042] like Figures 3 to 7As shown, the cross bar 21 has a plurality of first card slots 211 spaced apart and distributed on the same side of the cross bar 21, and the folding plate 22 has a strip slot 225 extending along the width direction of the main plate 10, and the two ends of the strip slot 225 extend to the first sub-plate 221 and the third sub-plate 223 respectively and penetrate the second sub-plate 222. When the paper pallet 1 is in use, the strip slot 225 on the first sub-plate 221 and the strip slot 225 on the third sub-plate 223 respectively form two second card slots 2251 that are carded with the first card slot 211, and the strip slot 225 on the second sub-plate 222 forms an avoidance opening 2252 to avoid the cross bar 21 area between two adjacent first card slots 211.

[0043] In this embodiment, the strip groove 225 is used to facilitate the formation of the second mounting groove 2251 and the avoidance opening 2252, and the mounting of the cross bar 21 and the folding plate 22 is achieved through the cooperation of the first mounting groove 211 and the second mounting groove 2251. By setting the avoidance opening 2252, it is avoided that during the mounting process of the cross bar 21 and the folding plate 22, the cross bar 21 will be stopped by the third sub-plate 223, making it impossible for the first mounting groove 211 and the second mounting groove 2251 to be mounted, thereby ensuring the reliability of the mounting of the cross bar 21 and the folding plate 22.

[0044] Furthermore, the area of ​​the cross bar 21 between the two first clamping grooves 211 respectively clamped with the two second clamping grooves 2251 located on the same folding plate 22 forms a limiting plate segment 212, and the limiting plate segment 212 penetrates into the frame structure from the avoidance opening 2252 and cooperates with the inner wall of the frame structure to limit the rotation of the cross bar 21 relative to the folding plate 22 and the movement of the cross bar 21 along the width direction of the folding plate 22. In this way, the relative position of the cross bar 21 and the folding plate 22 is further limited by the limiting plate segment 212, thereby ensuring the reliability and stability of the frame structure.

[0045] Specifically, the multiple sub-boards in this embodiment are all square boards, and the two ends of the strip groove 225 extend to the center positions of the first sub-board 221 and the third sub-board 223 respectively. The cross bar 21 has two groups of first card-mounting slots 211, and each group of first card-mounting slots 211 includes two first card-mounting slots 211. When the paper pallet 1 is in use, the two second card-mounting slots 2251 of the same folding plate 22 are respectively arranged on the first sub-board 221 and the third sub-board 223 of the frame structure along the width direction of the main board 10 and the openings are facing the side away from the main board 10. The opening of the first card-mounting slot 211 faces the second card-mounting slot 2251. During the installation of the cross bar, the first card-mounting slot 211 and the corresponding second card-mounting slot 2251 gradually overlap until the bottom walls of the multiple first card-mounting slots 211 are abutted against the bottom walls of the corresponding multiple second card-mounting slots 2251, thereby completing the installation of the cross bar 21. With this arrangement, the cross bar 21 and the sub-board will form a "cross" structure at the clamping position. The plates on both sides of the first clamping slot 211 and the plates on both sides of the second clamping slot 2251 restrict each other, so that the cross bar 21 and the sub-board will not move relative to each other, thereby ensuring that the cross bar 21 supports the frame structure.

[0046] Among them, in this embodiment, the cross bar 21 area on the side where the two first card slots 211 that are farthest apart from each other face away from each other forms a protruding section on one side of the protruding main board 10, and the length of the protruding section can be determined according to actual conditions, so as to reduce the footprint of the paper pallet 1 while ensuring the anti-dumping of the paper pallet 1, ensure the overall structural strength of the paper pallet 1, and the overall supporting effect of the paper pallet 1 on the carton 2.

[0047] like Figures 8 to 10 As shown, another embodiment of the utility model provides a paper pallet group, the paper pallet group includes a plurality of the above-mentioned paper pallets 1, the plurality of paper pallets 1 are arranged in sequence along the width direction of the paper pallet 1, when the plurality of paper pallets 1 are in use, any two adjacent paper pallets 1 are connected by a plurality of cross bars 21 of the two paper pallets 1, when the plurality of paper pallets 1 of the paper pallet group are connected, any paper pallet 1 is in use. With such arrangement, the connection of two adjacent paper pallets 1 can be achieved through a plurality of cross bars 21, which facilitates the molding of the paper pallet group, improves the functionality of the cross bars 21 and improves the applicability of the paper pallet group.

[0048] Specifically, when multiple paper pallets 1 of the paper pallet group are connected, multiple crosspieces 21 of the same paper pallet 1 protrude from one side of the paper pallet 1 along the width direction of the paper pallet 1, and the protruding parts of the multiple crosspieces 21 are connected to the multiple support groups 20 of the adjacent paper pallets 1 in a one-to-one correspondence. In this way, the crosspiece 21 can be used for two purposes. When it is applied to a single paper pallet 1, it plays an anti-dumping support effect. When it is applied to a paper pallet group, it plays a transfer role for two adjacent paper pallets 1, thereby improving the functionality and applicability of the crosspiece 21.

[0049] Furthermore, any supporting group 20 has two groups of second card slots 2251 spaced apart along the length direction of the main board 10, and multiple groups of second card slots 2251 in one paper pallet 1 correspond one-to-one to multiple groups of second card slots 2251 in an adjacent paper pallet 1. When multiple paper pallets 1 in the paper pallet group are connected, a cross bar 21 of one of the paper pallets 1 is inserted into one of the corresponding groups of second card slots 2251, and one end of the cross bar 21 protruding from the main board 10 of the paper pallet 1 is connected to another group of second card slots 2251 of the adjacent paper pallet 1.

[0050] In this embodiment, the multiple support groups 20 in any one paper pallet 1 correspond one-to-one to the multiple support groups 20 of the adjacent paper pallet 1, and the cross bar 21 of one of the paper pallets 1 is inserted into one of the second mounting grooves 2251 of one of the support groups 20, and one end of the cross bar 21 protruding from the paper pallet 1 is mounted on another set of second mounting grooves 2251 of the corresponding support group 20 of another paper pallet 1, and the cross bar 21 of another paper pallet 1 is arranged similarly. This arrangement enables staggered mounting of the cross bars 21 of the two paper pallets 1, and the ends of the two cross bars 21 protruding from each other are used for mounting with the support groups 20 of two different paper pallets 1 that fit each other, thereby ensuring the reliability and stability of the interconnection of the multiple paper pallets 1. Specifically, as Figures 7 to 10 As shown, the paper pallet set in this embodiment is formed by splicing two paper pallets 1.

[0051] like Fig.10 As shown, the cross bar 21 has a plurality of third card slots 213 spaced apart on the same side of the cross bar 21, the plurality of third card slots 213 divide one side of the cross bar 21 into three limiting sections 214 and a transition section 215, two of the three limiting sections 214 are located at both ends of the cross bar 21, and the other limiting section 214 and the transition section 215 are located in the middle area of ​​the cross bar 21, and when a plurality of paper pallets 1 of the paper pallet group are connected, the plurality of third card slots 213 are carded with the plurality of second card slots 2251 of the two paper pallets 1, wherein a limiting section 214 located at the end and a limiting section 214 located in the middle area of ​​the cross bar 21 are respectively arranged in the frame structure formed by the two folding plates 22 of the same paper pallet 1 and the same support group 20, and the other limiting section 214 located at the end is in the frame structure formed by a folding plate 22 of the corresponding support group 20 on the adjacent paper pallet 1.

[0052] In this embodiment, the clamping principle of the third clamping slot 213 and the second clamping slot 2251 is the same as that of the first clamping slot 211 and the second clamping slot 2251. When multiple paper pallets 1 of the paper pallet group are connected, the two limiting sections 214 located on both sides of the transition section 215 of the cross bar 21 of one of the paper pallets 1 are respectively inserted into the two frame structures of the same support group 20, the transition section 215 is located between the two frame structures and respectively cooperates with the side of the two frame structures close to each other, the other limiting section 214 protrudes from the paper pallet 1 and is inserted into the adjacent frame structure of the corresponding support group 20 of the adjacent paper pallet 1, and the cross bar 21 of another paper pallet 1 is arranged in the same manner. Such an arrangement is conducive to ensuring the staggered clamping of the cross bars 21 of the two paper pallets 1, while further ensuring the limitation of the relative position of the cross bar 21 and the folding plate 22, and ensuring the reliability and stability of the paper pallet group when in use.

[0053] It should be noted that the third card slot 213 and the second card slot 2251 of the cross bar 21 can be arranged on the same side or both sides of the cross bar 21. Preferably, a plurality of third card slots 213 are distributed on one side of the cross bar 21, and a plurality of second card slots 2251 are distributed on the other side of the cross bar 21, so as to avoid the situation that it is difficult to process or distinguish when a plurality of third card slots 213 and a plurality of second card slots 2251 are distributed on the same side of the cross bar 21, and the structural strength of the cross bar 21 is easily reduced, which is conducive to the processing of the cross bar 21 and ensures the structural strength of the cross bar 21. Optionally, the depth of the second card slot 2251 or the third card slot 213 is less than or equal to half of the width of the cross bar 21, so as to avoid the situation that the second card slot 2251 and the third card slot 213 overlap too much in the width direction of the cross bar 21, resulting in a reduction in the structural strength of the cross bar 21, and further ensure the structural strength of the cross bar 21.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0056] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0057] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0058] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0059] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
