Description

Technical Field

[0001] This utility model relates to the field of corrugated paper pallet technology, specifically a high load-bearing corrugated paper pallet. Background Technology

[0002] Currently, paper pallets on the market mainly use corrugated cardboard (including single-wall, double-wall, and triple-wall) or honeycomb cardboard as the base material. The mainstream structural forms are divided into two categories: one is the "folding / assembly" pallet, which is usually assembled from pre-die-cut and crimped panels (top and bottom panels) and independent foot blocks (usually block-shaped or column-shaped) through interlocking, locking tongues, adhesive bonding, or metal nail reinforcement. Its advantage is that the empty pallet can be folded, and the utilization rate of transportation and storage space is high. The other is the "one-piece molded" pallet, which uses hot pressing, molding, and other processes to directly press multiple layers of paper base materials into an integral structure with foot blocks and panels. It has strong integrity but requires large equipment investment and has low flexibility. To improve performance, existing technologies often add material layers to key parts (such as foot blocks), attach reinforcing strips, or apply moisture-proof and reinforcing coatings or impregnating agents such as wax or polymers to the surface / inside of the cardboard.

[0003] Despite the widespread use of existing paper pallets, current technologies still face numerous challenges, such as insufficient structural strength and stability. The connection between the foot block and the panel of an assembled pallet is a typical weak point in terms of mechanics. Under repeated forklift insertion and removal, long-distance transportation bumps, or high stacking pressure, it is prone to cracking, separation, or collapse, leading to load-bearing failure. Although integrated pallets have good overall integrity, the foot block area often experiences crushing deformation under concentrated loads. The overall edge crush strength and stacking strength are difficult to meet the requirements of heavy-duty or high-stack scenarios. Therefore, a high-load-bearing corrugated paper pallet is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-load-bearing corrugated paper pallet to solve the problem mentioned in the background art that the existing corrugated paper pallets have poor load-bearing capacity and are prone to cracking.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-load-bearing corrugated paper pallet includes a die-cut corrugated cardboard. The corrugated cardboard is folded upward to form a plurality of pallet feet with a horizontal structure. The top of each pallet foot has a plurality of first slots. A horizontally arranged first corrugated paper reinforcing rib is fixedly connected to the outside of each pallet foot. A second corrugated paper reinforcing rib perpendicular to the first corrugated paper reinforcing rib is fixedly connected to the outside of the first corrugated paper reinforcing rib. The bottom of the second corrugated paper reinforcing rib has a plurality of second slots corresponding to the positions of the first slots.

[0007] Preferably, both the first and second corrugated paper reinforcing ribs are bonded to the corrugated cardboard and pallet feet using environmentally friendly adhesive.

[0008] Preferably, the second slot is disposed on the outside of the first corrugated paper reinforcing rib and the tray foot and forms a mortise and tenon structure with it.

[0009] Preferably, the top of the tray foot and the top of the second corrugated paper reinforcing rib are horizontally aligned.

[0010] Preferably, the tray has three feet, the first corrugated paper reinforcing ribs have four, and the second corrugated paper reinforcing ribs have four.

[0011] Preferably, the first card slot has four slots and the second card slot has three slots.

[0012] Preferably, the first corrugated paper reinforcing rib is formed by folding the corrugated paper three times, and the second corrugated paper reinforcing rib is formed by folding the corrugated paper four times after die-cutting.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, by setting pallet feet, a first corrugated paper reinforcing rib, and a second corrugated paper, the load-bearing capacity of the paper pallet can be improved while reducing the amount of corrugated paper used, thereby reducing equipment and cost investment. Furthermore, the first and second corrugated paper reinforcing ribs are both set at the weak points of the paper pallet's mechanics, thereby increasing the structural stability of the paper pallet and reducing the possibility of cracking, separation, or collapse.

[0025] A high-load-bearing corrugated cardboard pallet includes a die-cut corrugated cardboard 1. The corrugated cardboard 1 is folded upwards to form multiple transverse pallet legs 2. Multiple first slots 3 are formed at the top of each pallet leg 2. A horizontally arranged first corrugated cardboard reinforcing rib 4 is fixedly connected to the outside of each pallet leg 2. A second corrugated cardboard reinforcing rib 5, perpendicular to the first corrugated cardboard reinforcing rib 4, is fixedly connected to the outside of the first corrugated cardboard reinforcing rib 4. Multiple second slots 6, corresponding to the positions of the first slots 3, are formed at the bottom of the second corrugated cardboard reinforcing rib 5. Both the first and second corrugated cardboard reinforcing ribs 4 and 5 are bonded to the corrugated cardboard 1 and pallet legs 2 using environmentally friendly adhesive. The second slots 6 are located on the outside of the first corrugated cardboard reinforcing ribs 4 and pallet legs 2, forming a mortise and tenon structure with them. The tops of the corrugated paper reinforcing ribs 5 are horizontally aligned. There are three tray feet 2, four first corrugated paper reinforcing ribs 4, four second corrugated paper reinforcing ribs 5, four first slots 3, and three second slots 6. The first corrugated paper reinforcing ribs 4 are formed by folding the corrugated paper three times, and the second corrugated paper reinforcing ribs 5 are formed by folding the corrugated paper four times after die-cutting. By setting the tray feet 2, the first corrugated paper reinforcing ribs 4, and the second corrugated paper, the load-bearing capacity of the paper pallet can be improved while reducing the amount of corrugated paper used, thus reducing equipment and cost investment. Furthermore, the first corrugated paper reinforcing ribs 4 and the second corrugated paper reinforcing ribs 5 are both set at the weak points of the paper pallet's mechanics, which can increase the structural stability of the paper pallet and reduce the possibility of cracking, separation, or collapse.

[0026] Workflow: When manufacturing corrugated cardboard pallets, firstly, utilizing the foldable nature of corrugated cardboard, a piece of corrugated cardboard 1 of suitable size is die-cut and creased. Then, it is folded downwards to form three transverse pallet legs 2, creating four first slots 3 on the legs. This portion of the corrugated cardboard 1 serves as the pallet surface structure. Next, four more sheets of corrugated cardboard are taken and folded three times to form the first corrugated cardboard reinforcing ribs 4. Then, four more sheets of corrugated cardboard are taken, die-cut and creased, and folded four times to form the second corrugated cardboard reinforcing ribs 5. Finally, the corrugated cardboard pallet can be assembled. The first corrugated cardboard reinforcing ribs 4 are glued to both sides of the pallet legs 2 using environmentally friendly adhesive. The second corrugated cardboard reinforcing ribs are then... The reinforcing rib 5 is inserted perpendicularly to the direction of the pallet foot 2, so that the second slot 6 is vertically aligned with the first slot 3, until the second slot 6 moves to the outside of the first corrugated paper reinforcing rib 4 and the pallet foot 2 and forms a mortise and tenon structure with them. The joint is then glued with environmentally friendly glue to complete the assembly of the device. The design of the pallet foot 2, the first corrugated paper reinforcing rib 4 and the second corrugated paper reinforcing rib 5 can improve the load-bearing capacity of the paper pallet while reducing the amount of corrugated paper used, thereby reducing the investment in equipment and costs. Furthermore, the first corrugated paper reinforcing rib 4 and the second corrugated paper reinforcing rib 5 are both set at the weak points of the paper pallet's mechanics, which can increase the structural stability of the paper pallet and reduce the possibility of cracking, separation or collapse.
