Description

Technical Field

[0001] This utility model relates to the field of factory cargo transportation technology, and in particular to an interlocking paper pallet. Background Technology

[0002] A pallet is a horizontal platform device used for the containerization, stacking, handling, and transportation of goods and products as unit loads. Pallets can be classified by material into wooden pallets, paper pallets, bamboo pallets, and plastic pallets, etc. Paper pallets typically use high-strength, high-grammage kraft paperboard and corrugated cardboard as the base material, which are then laminated and bonded to create a composite board with excellent compression, bending, and puncture resistance. For load-bearing structures, honeycomb paper cores, paper tubes, or profiles are commonly used as support legs. Existing paper pallets are usually assembled using a large amount of glue. This glued method not only wastes materials and increases production costs, but also makes the glued joints prone to detachment after a period of time, requiring re-gluing and increasing subsequent rework. Furthermore, paper pallets have relatively poor stability. Summary of the Invention

[0003] This invention provides an interlocking paper pallet, which aims to solve the problem of poor stability caused by the use of a large amount of glue for bonding in existing paper pallets.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] This utility model provides an interlocking paper pallet, including a base plate 1, a first combined plate 3, a second combined plate 4, and a crossbeam plate 5. The first combined plate 3 is adhered to the bottom of the base plate 1, the second combined plate 4 is inserted into the bottom of the first combined plate 3, and the crossbeam plate 5 is disposed between the base plate 1 and the first combined plate 3. The first combined plate 3 and the second combined plate 4 are arranged perpendicularly.

[0019] The base plate 1 is the support plate of the paper pallet, used to support items. The first combined plate 3 and the second combined plate 4 are inserted to form the support part at the bottom of the base plate 1. The crossbeam plate 5 spans between the first combined plate 3 and the base plate 1, filling the gap between them and improving the lateral structural stability. This paper pallet abandons the traditional assembly method of extensive gluing. Except for the first combined plate 3 and the base plate 1, which are connected by glue, the rest are physically locked using precision die-cut insertion slots and grooves, achieving quick tool-free assembly.

[0020] As an embodiment of the present utility model, the first combined plate 3 is provided with a first insertion groove 30, the first insertion groove 30 is provided near the end edge of the first combined plate 3, and at least two crossbeam plates 5 are provided in the first insertion groove 30.

[0021] In another embodiment of this utility model, the first insertion slot 30 is square in shape.

[0022] The first insertion slot 30 is used to place the crossbeam plate 5. The crossbeam plate 5 extends along the short axis of the paper pallet. The crossbeam plate 5 provides support for the base plate 1 and, through its engagement with the first insertion slot 30, reduces relative movement at the bottom of the paper pallet, thus improving the stability of the paper pallet. In this embodiment of the invention, three first combination plates 3 are provided, horizontally distributed on both sides and the middle of the bottom of the base plate 1. The crossbeam plate 5 connects the three first combination plates 3 in series. The insertion structure of the crossbeam plate 5 stabilizes the paper pallet, and the process is simple, easy to install, and reduces labor costs.

[0023] In another embodiment of the present invention, the first combined plate 3 is provided with a second insertion groove 31 in the middle, and a partition plate 32 is provided in the middle of the second insertion groove 31. A crossbeam plate 5 is placed on each side of the partition plate 32.

[0024] In another embodiment of this utility model, the second insertion slot 31 is square in shape.

[0025] The second insertion groove 31 has the same function as the first insertion groove 30, and is also used for placing the cross beam plate 5. However, since the second insertion groove 31 is located in the middle and needs to bear a part of the structure for adhesive bonding with the seat plate 1, the separation plate 32 is arranged in the second insertion groove 31, and the separation plate 32 serves as an adhesive bonding position in the middle of the seat plate 1. The separation plate 32 divides the second insertion groove 31 into two parts, and at least one cross beam plate 5 is arranged in each part. Designing the first insertion groove 30 and the second insertion groove 31 as square shapes is, on one hand, to adapt to the outer shape of the cross beam plate 5, and on the other hand, the square structures can be perfectly matched with each other, which reduces the gap between the plates and the grooves and improves stability.

[0026] As another embodiment of the utility model, third insertion grooves 40 are respectively provided at the position close to the end edge and in the middle of the second combination plate 4, and the first combination plate 3 is clamped in cooperation with the third insertion grooves 40.

[0027] As another embodiment of the utility model, a fourth insertion groove 33 is provided at the bottom of the first combination plate 3, and the fourth insertion groove 33 is inserted and matched with the third insertion groove 40.

[0028] As another embodiment of the utility model, the third insertion groove 40 and the fourth insertion groove 33 are square in shape.

[0029] The fourth insertion groove 33 at the bottom of the first combination plate 3 is inserted and combined with the third insertion groove 40 of the second combination plate 4, so as to realize the combination of the first combination plate 3 and the second combination plate 4. In the embodiment of the utility model, three second combination plates 4 are provided, the second combination plates 4 are perpendicular to the first combination plates 3, and a "grid-shaped" structure is formed at the bottom of the seat plate 1. Three third insertion grooves 40 are provided, which are used for matching connection with three first combination plates 3. The insertion fit of the square grooves of the third insertion groove 40 and the fourth insertion groove 33 constructs a stable mortise and tenon structure, and the mutual clamping of the two can also restrict displacement from each other. Both the first combination plate 3 and the second combination plate 4 are made of corrugated paperboard and fixed through the insertion structure, which is nail-free and glue-free, convenient for recycling and reusing, more environmentally friendly, and has high weight-bearing strength.

[0030] As another embodiment of the utility model, it further comprises corner guard plates 2, and the corner guard plates 2 are arranged along the edge of the seat plate 1. The corner guard plate 2 is composed of two L-shaped corner guards, which protect the edge of the seat plate 1. It prevents the paperboard from warping, enhances protection, improves wear resistance, and has a longer service life.

[0031] In another embodiment of this utility model, both the first combined plate 3 and the second combined plate 4 are provided with avoidance grooves 6. When the paper pallets are stacked, the avoidance grooves 6 can prevent interference with other paper pallets, and the avoidance grooves 6 can also reduce the weight of the paper pallets.

[0032] The paper pallet assembly process is as follows: The fourth insertion slot 33 of the first combination plate 3 is inserted into the third insertion slot 40 of the second combination plate 4, and the two are interlocked. A corresponding number of the crossbeam plates 5 are placed in the first insertion slot 30 and the second insertion slot 31. The corner guards 2 are pasted along the edge of the seat plate 1. Finally, the seat plate 1 and the first combination plate 3 are glued together, and the paper pallet assembly is completed.

[0033] This paper pallet uses only a small amount of environmentally friendly adhesive at key stress points, reducing adhesive usage by over 70% compared to traditional fully adhesive-bonded paper pallets. This reduction in adhesive use simplifies the production process and directly lowers the raw material and production costs per unit. The intuitive interlocking structure design allows workers to quickly assemble the pallets without training, significantly improving warehousing and pre-shipment preparation efficiency. The significantly reduced adhesive content makes the pallets easier to break down and pulp, increasing the recycling value and degradation efficiency of waste materials. Compared to wooden pallets, paper pallets are lighter, providing greater effective load-bearing capacity for logistics and saving on freight costs. Damaged individual components can be replaced locally, extending the overall lifespan and aligning with the circular economy concept. The precise interlocking structure design ensures more even stress distribution and overall structural stability, preventing delamination caused by glue aging.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
