Description

Technical Field

[0001] This invention relates to the field of heavy-duty pallet technology, and in particular to a recyclable heavy-duty pallet and a recycling method thereof. Background Technology

[0002] Currently, the mainstream pallets on the market are mainly divided into four categories, each with obvious defects, making it difficult to meet the requirements of environmental protection, load-bearing capacity, turnover, cost, and other aspects: 1. Wooden pallets: Made using traditional wood board nailing techniques, they have high costs for long-distance transport and maintenance, and cannot be recycled. Their large-scale use will consume forest resources and cause ecological waste. This type of pallet occupies the "mainstream market", but it is not environmentally friendly or economical.

[0003] 2. Plastic pallets: Made from petroleum resources, they have high mold costs and large carbon emissions. They are not suitable for production of irregular shapes and small batch orders, and are difficult to recycle and remanufacture, resulting in poor environmental performance. This type of pallet belongs to the "secondary mainstream market" and faces prominent problems in resource consumption and recycling.

[0004] 3. Paper pallets: Paper pallets replace wood and plastic, and can meet export standards without fumigation. However, most countries currently use honeycomb corrugated technology for manufacturing, with 80% of the production process being manual. This results in high production costs and low load-bearing capacity (both moisture-proof and load-bearing capacity are below 500kg). They can only be used once and cannot meet customers' core needs for environmental protection, moisture-proof, high load-bearing capacity, low cost, and reusability. The market share is as low as 6.5%, making it a "prospect market".

[0005] 4. Metal and composite material pallets: While they have high initial investment costs and are reusable, they are only suitable for short-distance and in-plant use, failing to meet long-distance transport needs, thus representing a "supplementary market." In summary, existing pallets all have varying degrees of shortcomings, necessitating a heavy-duty pallet that is environmentally friendly, has high load-bearing capacity, low cost, and is recyclable, along with corresponding recycling methods to fill this market gap. Summary of the Invention

[0006] The purpose of this invention is to provide a recyclable heavy-duty pallet and its recycling method, which solves the technical problems of existing pallets, such as poor environmental performance, low load capacity, difficulty in recycling, high cost, and inconvenience in turnover.

[0007] To achieve the above objectives, the present invention provides a recyclable heavy-duty pallet, comprising a pallet body, pallet crossbeams and pallet longitudinal beams. The pallet body includes a plurality of support legs arranged evenly in the transverse and longitudinal directions, and the support legs are arranged in a rectangular array. Several pallet crossbeams are provided, which are arranged laterally along the pallet body and support the pallet body. Several pallet longitudinal beams are provided, which are arranged longitudinally along the pallet body and support the pallet crossbeams. The pallet crossbeams are perpendicular to the pallet longitudinal beams. The pallet crossbeam includes a support crossbeam and a fork support crossbeam, with the fork support crossbeams fitted onto the support crossbeam and evenly distributed. The pallet longitudinal beams include support longitudinal beams and fork support longitudinal beams, with the fork support longitudinal beams fitted onto the support longitudinal beams and evenly distributed.

[0008] Preferably, all connections of the support legs, support beams, fork support beams, support longitudinal beams, and fork support longitudinal beams are made using hot melt adhesive.

[0009] Preferably, the support legs are arranged in an n×m array, where n represents the number of rows of horizontally arranged support legs and m represents the number of columns of vertically arranged support legs. A total of n×m support legs are arranged, where n≥2 and m≥2.

[0010] Preferably, the number of pallet crossbeams is the same as the number of rows of horizontally arranged support legs, and the number of pallet longitudinal beams is twice the number of columns of vertically arranged support legs.

[0011] Preferably, the support legs, support beams, and fork support beams are all made of paper tubes with openings on both sides and hollow interiors. The support beams are inserted into and pass through the horizontally arranged support legs, and the fork support beams are distributed between two adjacent horizontally arranged support legs.

[0012] Preferably, the top of the fork support beam is flush with the top of the support leg.

[0013] Preferably, both the support longitudinal beam and the fork support longitudinal beam are made of paper tubes that are open at both ends and hollow. The support longitudinal beams are distributed on both sides of the longitudinally arranged support legs. The support longitudinal beams are located at the bottom of the support crossbeams and support the support crossbeams. The fork support crossbeams are distributed between adjacent support crossbeams.

[0014] Preferably, the top of the fork support beam is flush with the top of the support leg.

[0015] Preferably, the forklift laterally or longitudinally forks into and supports the entire recyclable heavy-duty pallet, with the forklift crossbeam and forklift longitudinal beam serving as the forklift forking and support components.

[0016] The present invention also provides a method for recycling heavy-duty pallets, comprising the following steps: Step 1, Recycling and Collection: Collect scrapped, idle or used recyclable heavy pallets and transport them to the designated recycling and processing area. Step 2, Non-destructive disassembly: After the hot melt adhesive has deteriorated, disassemble using a room temperature physical peeling method. Use a special tool to tap the joints of each component to allow them to separate naturally. First, remove the entire pallet longitudinal beam and pallet cross beam from the support legs in sequence. Then, remove the fork support longitudinal beam and fork support cross beam from the support longitudinal beam and support cross beam respectively. Step 3, Classification and Testing: All disassembled components are classified and collected according to type, and each component is transported to the target factory for reuse. After arriving at the destination, each component is subjected to appearance and performance testing. Step 4, Cleaning and Repair Steps: Clean the reusable components that have passed the inspection. Use compressed air to blow away debris inside the paper tube, wipe the surface stains with a damp cloth, and then wipe it dry with a dry cloth. Step 5, Reassembly: Reassemble according to the original pallet structure design requirements; First, arrange the support legs neatly in an n×m rectangular array, then fit the fork support beams onto the support beams to complete the pallet beam assembly. Insert the assembled pallet beams into and through the horizontally arranged support legs, ensuring that the fork support beams are evenly distributed between adjacent horizontal support legs, with the top of the fork support beams flush with the top of the support legs; Next, fit the fork support longitudinal beams onto the support longitudinal beams to complete the pallet longitudinal beam assembly. Set the assembled pallet longitudinal beams according to the longitudinally arranged support legs, placing the support longitudinal beams at the bottom of the support beams to support the support beams. The fork support longitudinal beams are evenly distributed between adjacent support beams, with the top of the fork support longitudinal beams flush with the top of the support legs; During the assembly process, the joints of each component are sequentially bonded and fixed with hot melt adhesive; Step Six, Re-inspection: Conduct a comprehensive inspection on the reassembled recyclable heavy-duty pallet, checking the regularity of the support leg array, the firmness of the connections of each component, the positional accuracy of the fork support crossbeam and fork support longitudinal beam, and the overall load-bearing stability; after passing the inspection, it can be put into secondary and multiple cycles of use; for reassembled pallets that fail the inspection, disassemble them, re-inspect the components, replace the unqualified parts, and reassemble and inspect them again until they pass the inspection.

[0017] The advantages and positive effects of the recyclable heavy-duty pallet and its recycling method described in this invention are as follows: 1. Using paper tubes as the core component, paper replaces wood and plastic, effectively reducing the consumption of forest resources and dependence on oil resources, lowering carbon emissions, and exempting them from fumigation for export, which aligns with environmental protection policies and export requirements; at the same time, it is equipped with a dedicated recycling method, relying on the detachable characteristics of hot melt adhesive to achieve component recycling and reuse, damaged components can be cut and reused, and waste can be sorted and disposed of, greatly reducing resource waste and solving the pain points of existing pallets being difficult to recycle and disposable; 2. Through the rectangular array design of the support legs, combined with the cooperation of the support beams, fork support beams, support longitudinal beams, and fork support longitudinal beams, the defects of existing paper pallets, such as low load capacity and insufficient moisture resistance, are overcome. It can meet the load-bearing requirements of heavy goods. The fork support beams and fork support longitudinal beams support forklifts to fork in both the horizontal and vertical directions, making it suitable for long-distance disassembly and turnover as well as various usage scenarios. It solves the problem that metal and composite material pallets cannot be turnovered over long distances, and centralized shipping greatly reduces transportation costs. 3. The components are made of standardized paper tubes, eliminating the need for high mold investment. Compared with plastic and metal pallets, the production threshold is low, and it avoids the drawback of 80% manual production of existing paper pallets. Mass production can be achieved, and it is also suitable for irregular shapes and small batch orders, which greatly reduces production and usage costs. Recycling and reuse further reduce long-term usage costs, taking into account both economy and practicality. 4. All components are connected with hot melt adhesive, which provides a strong bond and high stability, meeting the load-bearing requirements of heavy-duty pallets. At the same time, the hot melt adhesive can be disassembled after failure, and the disassembly process does not require sharp tools, achieving non-destructive disassembly. This facilitates the recycling, transportation, and reassembly of components, solving the problems of inconvenient repair of wooden pallets and difficulty in recycling and remanufacturing plastic pallets. 5. Taking into account multiple requirements such as environmental protection, high load capacity, low cost, reusability, and easy recycling, it can replace existing mainstream and secondary mainstream pallets, fill the existing market gap, and is suitable for long-distance turnover and short-distance use in various industrial and logistics scenarios. It effectively increases the market share of paper pallets and has extremely high practical value and promotion significance.

Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] Example: like Figure 1 , Figure 2 As shown, this invention provides a recyclable heavy-duty pallet, including a pallet body 1, pallet crossbeams 2, and pallet longitudinal beams 3. The pallet body 1 includes a plurality of support legs 101 arranged uniformly in the horizontal and vertical directions, and the support legs 101 are arranged in a rectangular array. The support legs 101 are arranged in an n×m array, where n represents the number of rows of horizontally arranged support legs 101, and m represents the number of columns of vertically arranged support legs 101. A total of n×m support legs 101 are provided, where n≥2 and m≥2.

[0025] Several pallet crossbeams 2 are provided, which are arranged laterally along the pallet body 1 and support the pallet body 1. Several pallet longitudinal beams 3 are provided, which are arranged longitudinally along the pallet body 1 and support the pallet crossbeams 2. The pallet crossbeams 2 are arranged perpendicular to the pallet longitudinal beams 3. The number of pallet crossbeams 2 is the same as the number of rows of the laterally arranged support legs 101, and the number of pallet longitudinal beams 3 is twice the number of columns of the longitudinally arranged support legs 101.

[0026] like Figure 3As shown, the pallet crossbeam 2 includes a support crossbeam 201 and a fork support crossbeam 202. The fork support crossbeam 202 is fitted onto the support crossbeam 201 and is evenly distributed. The support legs 101, support crossbeam 201, and fork support crossbeam 202 are all made of hollow paper tubes with openings on both sides. The support crossbeam 201 is inserted entirely into and passes through the horizontally arranged support legs 101. The fork support crossbeam 202 is distributed between two adjacent horizontally arranged support legs 101. The top of the fork support crossbeam 202 is flush with the top of the support leg 101.

[0027] like Figure 4 As shown, the pallet longitudinal beam 3 includes a support longitudinal beam 301 and a fork support longitudinal beam 302. The fork support longitudinal beam 302 is fitted onto the support longitudinal beam 301 and is evenly distributed. Both the support longitudinal beam 301 and the fork support longitudinal beam 302 are made of paper tubes that are open at both ends and hollow. The support longitudinal beam 301 is distributed on both sides of the longitudinally arranged support legs 101. The support longitudinal beam 301 is located at the bottom of the support crossbeam 201 and supports the support crossbeam 201. The fork support crossbeam 202 is distributed between adjacent support crossbeams 201. The top of the fork support longitudinal beam 302 is flush with the top of the support leg 101.

[0028] like Figure 5 As shown, the forklift can fork into and support the entire recyclable heavy-duty pallet in the horizontal or vertical direction. The fork support crossbeam 202 and the fork support longitudinal beam 302 are the forklift fork entry and support parts.

[0029] All connections of the support leg 101, support beam 201, fork support beam 202, support longitudinal beam 301, and fork support longitudinal beam 302 are made using hot melt adhesive. Any specifications of each component of the heavy-duty pallet used in this invention, including the support leg 101, support beam 201, fork support beam 202, support longitudinal beam 301, and fork support longitudinal beam 302, can be manufactured.

[0030] In this embodiment, a 100×100 recyclable heavy-duty pallet was used for dynamic testing of 1.71 tons and static testing of 2.6 tons. Both tests were normal and the heavy-duty pallet load-bearing requirements can be met.

[0031] The present invention discloses a method for recycling heavy-duty pallets, comprising the following steps: Step 1, Recycling and Collection: Collect all scrapped, idle, or used recyclable heavy-duty pallets and transport them to the designated recycling area. Handle with care during transport to avoid damage to the paper tube components (support legs 101, pallet crossbeams 2, pallet longitudinal beams 3) due to collisions or squeezing, and ensure the integrity of the components.

[0032] Step 2, Non-destructive disassembly: After the hot melt adhesive has deteriorated, disassemble using a physical peeling method at room temperature. Use special tools (such as plastic pry bar or rubber hammer) to gently tap the joints of each component to allow them to separate naturally. Do not use sharp tools to cut or pry, as this may damage the inner wall and surface structure of the paper tube.

[0033] During disassembly, first remove the entire pallet longitudinal beam 3 and the entire pallet crossbeam 2 from the support leg 101 in sequence, and then remove the fork support longitudinal beam 302 and the fork support crossbeam 202 from the support longitudinal beam 301 and the support crossbeam 201 respectively, to ensure that all reusable components are free from structural damage.

[0034] Step 3, Classification and Testing: All disassembled components are classified and collected according to type (support leg 101, support beam 201, fork support beam 202, support longitudinal beam 301, and fork support longitudinal beam 302 are stored separately), and each component is transported to the target factory area for reuse. After arriving at the destination, each component is subjected to appearance and performance testing.

[0035] The key points of the inspection include: whether the paper tube is damaged, cracked, or deformed; whether there are serious stains or corrosion on the surface; and whether there is too much hot melt adhesive residue. Simple load-bearing tests are conducted on the support leg 101, pallet crossbeam 2, and pallet longitudinal beam 3. Damaged, deformed, substandard load-bearing capacity, and irreparable components are removed, while intact components that meet the original design load-bearing requirements are retained.

[0036] Step 4, Cleaning and Repair: Clean the reusable components that have passed the inspection. Use compressed air to blow away debris inside the paper tube, wipe the surface stains with a damp cloth, and then wipe it dry with a dry cloth to ensure that the surface of the component is free of dust, residual hot melt adhesive debris, and oil stains.

[0037] For components with a small amount of hot melt adhesive residue on the surface, use low-temperature heating (temperature not exceeding 80℃) to soften the residual adhesive layer, and then gently scrape it off with a plastic scraper to avoid damaging the surface of the paper tube; for slightly deformed paper tube components, use special clamps to correct them and restore their standard dimensions.

[0038] Step 5, Reassembly: Reassemble according to the original pallet structure design requirements; First, arrange the support legs 101 neatly in an n×m rectangular array to ensure accurate positioning; then, fit the fork support beam 202 onto the support beam 201 to complete the pallet beam 2 assembly. Insert the assembled pallet beam 2 into and through the horizontally arranged support legs 101, so that the fork support beam 202 is evenly distributed between two adjacent horizontal support legs 101, and the top of the fork support beam 202 is flush with the top of the support leg 101; then, fit the fork support longitudinal beam 302 onto the support longitudinal beam 301 to complete the pallet longitudinal beam 3 assembly. Set the assembled pallet longitudinal beam 3 according to the longitudinally arranged support legs 101. Place the support longitudinal beam 301 at the bottom of the support beam 201 to support the support beam 201. The fork support longitudinal beam 302 is evenly distributed between adjacent support beams 201, and the top of the fork support longitudinal beam 302 is flush with the top of the support leg 101.

[0039] During the assembly process, hot melt adhesive is used to bond and fix the joints of each component in sequence. When applying hot melt adhesive, ensure that the adhesive layer is uniform and of appropriate thickness. After bonding, press and fix until the adhesive layer solidifies to ensure that the connection is firm and there is no looseness.

[0040] Step Six, Re-inspection: Conduct a comprehensive inspection of the reassembled recyclable heavy-duty pallet, focusing on the regularity of the support leg 101 array, the firmness of the connections between components, the positional accuracy of the fork support crossbeam 202 and fork support longitudinal beam 302, and the overall load-bearing stability, ensuring compliance with all requirements of the original technical solution. After passing the inspection, mark the pallet with a recycling symbol, and it can be used for secondary and multiple cycles. For reassembled pallets that fail the inspection, disassemble them, re-inspect the components, replace the defective parts, and reassemble and inspect them again until they pass.

[0041] For damaged paper tube components that cannot be directly reused, they can be cut and repaired to be processed into suitable auxiliary support components, further improving resource utilization. Waste such as hot melt adhesive debris and damaged paper tubes generated during the recycling process are sorted and recycled to avoid environmental pollution.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
