Description

Technical Field

[0001] This utility model relates to the field of corrugated paper pallet technology, specifically a multi-layer composite reinforced corrugated paper pallet. Background Technology

[0002] Currently, paper pallets on the market mainly use corrugated cardboard or honeycomb cardboard as the base material. They are mainly divided into assembled pallets and one-piece molded pallets. Assembled pallets are assembled from pre-die-cut and crimped panels and feet by means of interlocking, locking tongues, adhesive bonding or metal nail reinforcement, etc., which have high utilization of transportation and storage space. One-piece molded pallets are made by pressing multiple layers of paper base materials directly into an integral structure with feet and panels through hot pressing, molding and other processes, which has better integrity.

[0003] Existing corrugated paper pallets lack structural strength and stability, and their overall edge crush strength and stacking strength are insufficient to meet the requirements of heavy or high stacking scenarios. The connection between the foot block and the panel of the assembled pallet is a typical weak point in mechanical structure. Under repeated forklift insertion and removal, long-distance transportation bumps, or high stacking pressure, it is very easy to crack, separate, or collapse, leading to load-bearing failure. The foot block area of ​​the integrated pallet is also often crushed or deformed during centralized transportation. Therefore, a corrugated paper pallet with multi-layer composite reinforcing ribs is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated paper pallet with multi-layer composite reinforcing ribs to solve the problem that some existing corrugated paper pallets have insufficient structural strength and stability, and the overall edge crush strength and stacking strength are difficult to meet the needs of heavy or high stacking scenarios.

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

[0006] A multi-layer composite reinforced corrugated paper pallet includes a pallet body, vertical reinforcing ribs, horizontal reinforcing ribs, and pallet bases. The pallet body includes a pallet panel, with three pallet feet on the upper side of the panel and four limiting feet on the upper side of each foot. Adhesive edges are provided on both the left and right sides of the pallet panel. Three pairs of vertical reinforcing ribs are provided on the upper side of the pallet body, each including a first vertical reinforcing rib. The opposing sides of each pair of first vertical reinforcing ribs are respectively bonded to the left and right sides of the pallet feet. Three second vertical reinforcing ribs are bonded to the upper side of each first vertical reinforcing rib and connected to the pallet feet. Four horizontal reinforcing ribs are provided on the upper side of the pallet body, each including a thickened horizontal reinforcing rib. Three engaging grooves are provided on the lower side of each thickened horizontal reinforcing rib, engaging with the paired first vertical reinforcing ribs. Three pallet bases are provided on the upper side of the pallet body, each including a stabilizing base bonded to the adhesive edges. Multiple gripping grooves are provided on the upper side of each stabilizing base.

[0007] Preferably, the pallet feet are all of the "mountain" shaped structure, and the pallet feet are all formed by folding two layers of corrugated paper after die-cutting and pressing.

[0008] Preferably, the distance between the protrusions of the limiting foot block and the pallet foot block is equal to the thickness of the thickened transverse reinforcing rib, and the thickened transverse reinforcing rib passes through the gap between the protrusions of the limiting foot block and the pallet foot block.

[0009] Preferably, both the first and second vertical reinforcing ribs are formed by folding several layers of corrugated paper after die-cutting and creasing, and the shape of the second vertical reinforcing rib is consistent with the shape of the protrusion of the pallet foot block.

[0010] Preferably, the thickened transverse reinforcing ribs are formed by folding several layers of corrugated paper after die-cutting and pressing, and a pair of rectangular corrugated paper are glued to both the front and rear sides of the thickened transverse reinforcing ribs.

[0011] Preferably, the width of the locking groove in the left and right directions is equal to the sum of the thickness of the pallet foot block and the two first vertical reinforcing ribs, and the locking groove is located at the lower middle position, the lower left end, and the lower right end of the thickened transverse reinforcing rib, respectively.

[0012] Preferably, the stabilizing bases are all U-shaped structures, and the left inner wall and right inner wall of the stabilizing base are respectively bonded to the second vertical reinforcing rib located on the far left and the second vertical reinforcing rib located on the far right.

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

[0014] In this invention, by setting pallet feet, limiting feet, first vertical reinforcing ribs, second vertical reinforcing ribs, thickened horizontal reinforcing ribs, and a stable base, the device can form a foot base by folding pallet feet and limiting feet. The first and second vertical reinforcing ribs reinforce the foot base, which can effectively improve the structural strength of the device. At the same time, the thickened horizontal reinforcing ribs, together with the first vertical reinforcing ribs, form a grid support structure. The stable base forms a bottom support plane, which can effectively improve the stability of the device. This allows the device to meet the needs of heavy or high stacking scenarios and effectively avoid the problems of cracking, separation, collapse, crushing, or deformation of the foot base.

[0026] Please see Figure 1-7 This utility model provides a technical solution:

[0027] A multi-layer composite reinforced corrugated paper pallet includes a pallet body 1, vertical reinforcing ribs 2, horizontal reinforcing ribs 3, and a pallet base 4. The pallet body 1 includes a pallet panel 11, with three pallet feet 12 on the upper side of the pallet panel 11, and four limiting feet 13 on the upper side of each pallet foot 12. Adhesive edges 14 are provided on both the left and right sides of the pallet panel 11. Three pairs of vertical reinforcing ribs 2 are provided on the upper side of the pallet body 1, each vertical reinforcing rib 2 including a first vertical reinforcing rib 21. The opposing sides of each pair of first vertical reinforcing ribs 21 are respectively connected to the pallet feet 1. The left and right sides of the tray are bonded together. The upper side of the first vertical reinforcing rib 21 is provided with three second vertical reinforcing ribs 22 that are bonded to the tray foot block 12. The upper side of the tray body 1 is provided with four tray horizontal reinforcing ribs 3. Each tray horizontal reinforcing rib 3 includes a thickened horizontal reinforcing rib 31. The lower side of the thickened horizontal reinforcing rib 31 is provided with three engaging grooves 32 that engage with the paired first vertical reinforcing ribs 21. The upper side of the tray body 1 is provided with three tray bases 4. Each tray base 4 includes a stabilizing base 41 that is bonded to the bonding edge 14. The upper side of the stabilizing base 41 is provided with multiple gripping grooves 42.

[0028] All pallet feet 12 are "mountain" shaped structures, formed by folding two layers of corrugated paper after die-cutting and creased. The folded pallet feet 12 and the limiting feet 13 form the foot base. The distance between the protrusions of the limiting feet 13 and the pallet feet 12 is equal to the thickness of the thickened transverse reinforcing ribs 31. The thickened transverse reinforcing ribs 31 pass through the gap between the protrusions of the limiting feet 13 and the pallet feet 12, thus limiting the thickness of the thickened transverse reinforcing ribs 31 through the cooperation of the limiting feet 13 and the pallet feet 12. The first vertical reinforcing rib 21 and the second vertical reinforcing rib 22 are both formed by folding several layers of corrugated paper after die-cutting and creased. The shape of the second vertical reinforcing rib 22 is consistent with the shape of the protrusions of the pallet feet 12, thus reinforcing the foot base. The thickened transverse... The reinforcing ribs 31 are all formed by folding several layers of corrugated paper after die-cutting and pressing. A pair of rectangular corrugated paper are glued to both the front and back sides of the thickened transverse reinforcing ribs 31. The thickened transverse reinforcing ribs 31, together with the first vertical reinforcing ribs 21, can form a grid support structure. The width of the locking grooves 32 in the left and right directions is equal to the sum of the thickness of the tray foot block 12 and the two first vertical reinforcing ribs 21. The locking grooves 32 are located at the lower middle, lower left end, and lower right end of the thickened transverse reinforcing ribs 31, respectively. The thickened transverse reinforcing ribs 31 can be locked onto the pairs of first vertical reinforcing ribs 21 through the locking grooves 32. The stabilizing bases 41 are all "U" shaped structures. The left inner side wall and the right inner side wall of the stabilizing base 41 are glued to the second vertical reinforcing rib 22 located on the leftmost side and the second vertical reinforcing rib 22 located on the rightmost side, respectively. The stabilizing bases 41 can form a bottom support plane.

[0029] Workflow: The entire device is formed by folding and bonding die-cut corrugated paper with environmentally friendly adhesive. During production, the die-cut corrugated paper is first folded to form the pallet body 1, vertical reinforcing ribs 2, horizontal reinforcing ribs 3, and pallet base 4. Then, the first vertical reinforcing rib 21 and the second vertical reinforcing rib 22 are bonded to the pallet foot blocks 12 on the upper side of the pallet panel 11. The engaging groove 32 is engaged with the paired first vertical reinforcing ribs 21, and the limiting foot blocks 13 cooperate with the pallet foot blocks 12. The thickened transverse reinforcing rib 31 can be limited to prevent it from shifting relative to the pallet panel 11 in the front-to-back direction. A pair of rectangular corrugated paper are adhered to both the front and rear sides of the thickened transverse reinforcing rib 31. The rectangular corrugated paper protects the transverse reinforcing rib 31 from forklift tooth impacts. Next, the left and right inner walls of the stabilizing base 41 are adhered to the leftmost and rightmost second vertical reinforcing ribs 22 and 22, respectively, to secure the base. The left and right sides of the base 41 are respectively bonded to the adhesive edges 14 to complete the assembly of the device. The device can be easily picked up through the gripping slot 42 and inverted so that the tray panel 11 faces upward, allowing items to be placed on the upper side of the tray panel 11. The device can form a foot base by folding the tray foot block 12 and limiting foot block 13. The foot block is reinforced by the first vertical reinforcing rib 21 and the second vertical reinforcing rib 22, which can effectively improve the structural strength of the device. At the same time, the thickened horizontal reinforcing rib 31, together with the first vertical reinforcing rib 21, forms a grid support structure. The stable base 41 forms a bottom support plane, which can effectively improve the stability of the device. This allows the device to meet the needs of heavy or high stacking scenarios and effectively avoid the problems of cracking, separation, collapse, crushing or deformation of the foot block. Because the device has the characteristics of high load-bearing capacity, no wood chips, large lifting capacity, environmental protection, shock resistance and easy recycling, it can be widely used in the production and distribution of pharmaceuticals, food and semiconductors.
