Description

Technical Field

[0001] This invention relates to the field of industrial packaging technology, and in particular to a recyclable iron-wood combination packaging chassis and a boxing method. Background Technology

[0002] Traditional packaging for large industrial equipment primarily relies on disposable wooden crates. This existing technology has the following significant drawbacks: First, material costs are high and specifications are inconsistent. There is a lack of standardized inventory for main materials, and long-sized materials often need to be purchased on an ad-hoc basis. The existing wooden crate chassis materials come in a wide variety of specifications, resulting in high procurement and management costs.

[0003] Secondly, on-site operation efficiency is low. The installation of dunnage and skids requires manual measurement, drilling, and screw installation, which is not only labor-intensive but also causes serious wood dust pollution on site and takes a long time to install equipment.

[0004] Furthermore, storage, transportation, and safety hazards are prominent. Large containers need to be pre-stitched, are prone to deformation and impact, and require large storage areas; on-site lifting and installation require multiple people to work together, and there are safety risks associated with the chassis flipping operation.

[0005] Finally, traditional packaging is not recyclable. The nailed structure is difficult to disassemble, and almost all wooden components are destroyed, making them unusable and resulting in serious waste of wood and solid waste.

[0006] Therefore, there is an urgent need for a recyclable iron-wood combination packaging chassis and boxing method that is economical, highly safe, highly adaptable to working conditions, and reusable. Summary of the Invention

[0007] The present invention aims to overcome the above-mentioned defects and provide a recyclable, modular, quick-assembly and disassembly on-site iron-wood combination packaging chassis and box assembly method that can adapt to various handling conditions, so as to solve the problems of traditional packaging being non-recyclable, having low efficiency in on-site drilling, difficulty in switching bottom working conditions, and cumbersome box wall fixing.

[0008] This invention provides the following technical solution: A recyclable iron-wood combination packaging chassis includes at least two parallel and spaced skids. The skids are made of metal square tubes, and their bottoms are detachably connected to auxiliary skids or pads via bolts. The auxiliary skids have a smaller cross section and a height adapted to container rails for container pushing operations. The pads have a larger cross section for forklift handling operations. By changing the bottom components, one chassis can be used in different logistics scenarios, greatly improving versatility. Multiple sets of guide slots are opened along the axial direction on the top side of the skid; It also includes several wooden components and detachable metal connectors. The metal connectors are L-shaped iron pieces, with one side plate locked to the wooden component by fasteners, and the other side plate having slots at both ends. During installation, the slots engage with the sides of the guide slot. Rotating the L-shaped iron piece within the guide slot switches between the locked and released states, allowing the wooden component to be detachably fixed to the skid without nails. Compared to traditional nailing, this structure achieves truly non-destructive disassembly.

[0009] Furthermore, a through hole is provided on the side wall of the skid, which is used to connect the iron plate reinforcement through bolts to improve the overall load-bearing capacity of the chassis.

[0010] Furthermore, the wooden components include transverse top timbers and longitudinal bottom timbers connected in a grid pattern. The transverse top timbers are vertically distributed above the longitudinal bottom timbers, and the longitudinal bottom timbers are arranged parallel to the skids and are positioned between the two sets of skids. This grid structure increases the contact area and prevents the goods from sinking. Since the transverse top timbers are pressed together by L-shaped iron parts, their spacing and quantity can be flexibly adjusted according to the position of the bottom support point of the goods, without the need for on-site drilling, and can adapt to the center of gravity distribution of different specifications of equipment.

[0011] Furthermore, rectangular panel modules are arranged on the wooden components and laid on top of the wooden components. The panel modules can be made of solid wood boards, plywood, or modular boards that combine both. Users can flexibly choose materials according to their needs for moisture protection, cost, etc., thus realizing customized configuration of packaging.

[0012] Furthermore, to limit the displacement of the panel module, two sets of end pieces are installed at both ends of the skid, perpendicular to the skid. These end pieces, combined with L-shaped iron components, form a limiting frame around the panel module. Specifically, a through hole is provided within each end piece, and a nut block is fixed to a slider plate that slides within a guide slot. Bolts pass through the through hole and lock the nut block. This slider-nut block structure allows the end pieces to be adjusted arbitrarily along the length of the skid, accommodating panel modules of different widths, and provides a secure connection.

[0013] Furthermore, it also includes a hook assembly, which comprises an integrally connected U-shaped support and a hanging body. The hanging body is attached to the skid, with a hook at one end engaging in a guide slot, and the other end vertically connected to the end of the U-shaped support. The U-shaped support is used to support the bottom edge of the vertical box wall panel. Compared to traditional nailing, this assembly enables rapid positioning and suspension of the bottom of the box wall.

[0014] Furthermore, to enhance the stability of the hook, side holes are provided on both sides of the U-shaped support. One set of side holes is secured to the skid with a first screw to prevent the hook from sliding horizontally; the other set of side holes is secured to the vertical box wall panel with a second screw to prevent the box wall from tipping over or shifting laterally. This double securing ensures safe transportation.

[0015] Furthermore, to facilitate the connection of the bottom components, a second through hole is provided on the bottom of the skid. The bolted fitting is screwed onto the auxiliary skid or padding through the second through hole. Specifically, the second through hole aligns with a guide slot, allowing the operator to reach a tool through the guide slot from above the chassis, insert the bolted fitting through the inside of the square tube, and lock the bottom component via the second through hole. This design avoids blindly tightening bolts inside the enclosed square tube, greatly reducing assembly difficulty.

[0016] The present invention also provides a method for assembling a box using the above-mentioned chassis, comprising the following steps: S1 chassis assembly: Select the skid spacing according to the equipment width, fix the auxiliary skids or pads to the bottom of the skids with screws, arrange the wooden components according to the support point position of the bottom of the equipment, fix the wooden components with metal connectors and snap them into the guide grooves of the skids to realize the connection between the wooden components and the skids; S2 Laying and Positioning: Lay the panel modules on the wooden structure and hoist the equipment onto the wooden structure and panel modules; S3 vertical wall enclosure: Install hook assemblies on the side of the skid, fix the bottom of the two sets of vertical box wall panels to the U-shaped support of the hook assembly, and place the two sets of horizontal box wall panels on the skid and connect them to the two sets of vertical box wall panels to form a packaging box; S4 Top Cover Packaging and Disassembly: Install the top cover on the packaging box to complete the packaging; during disassembly, loosen the top cover, box wall panel, remove the L-shaped iron piece and rotate 90° to disengage the slot from the guide slot, achieving non-destructive disassembly, and classify and recycle each component for reuse.

[0017] The beneficial effects of this invention are: 1. After the optimization of the metal connector structure, the cost per set has been significantly reduced. After multiple rounds of amortization, the cost per use is lower than that of disposable packaging. 2: Completely eliminates on-site drilling and extensive nailing operations. The slot rotation locking mechanism of the L-shaped iron parts and the hook assembly mechanism greatly shorten on-site assembly time and eliminate sawdust pollution. 3: By replacing the auxiliary skids or pads at the bottom of the skid, the same chassis can adapt to both the sliding rail propulsion of containers and the forklift handling in the warehouse, solving the pain point of difficulty in adapting large packaging logistics. 4. The spacing between wooden components is adjustable, the position of the end pieces is adjustable, and the panel material is optional, which can perfectly adapt to the packaging needs of equipment of different sizes and weights. 5. The metal square tube frame, reinforced with optional connecting iron plates, enhances load-bearing capacity; all components are disassembled and recyclable, greatly reducing the consumption of forest resources and the generation of solid waste.

Detailed Implementation

[0019] Example 1: like Figure 1-10 As shown, a recyclable iron and wood combination packaging chassis, in this embodiment, firstly, two skids 1 as the main load-bearing structure are prepared. The skids 1 are, for example, carbon steel square tubes of 100mm×100mm. A set of guide slots 11 are opened on the top side of the skids 1 along the axial direction at intervals of, for example, 200mm. At the same time, through holes 2 13 are opened on the bottom of the skids 1, which are aligned with the guide slots 11, and through holes 12 are opened on the side wall. For forklift handling operations, a hardwood pad 8 with a large cross-sectional dimension is selected. During assembly, the pad 8 is attached to the bottom surface of the skid 1. The operator inserts a socket wrench through the guide slot 11 at the top of the skid 1, passes it through the inside of the square tube, and screws the bolt into the pre-embedded nut of the pad 8 through the through hole 13, thereby firmly locking the pad 8 under the skid 1. This structure increases the ground contact area, making it easier for the forklift forks to insert.

[0020] Next, install the wooden component 2. The wooden component 2 is made of multiple horizontal top woods 21 and multiple vertical bottom woods 22 nailed together in a grid pattern. Place the wooden component 2 on top of the skid 1, so that the vertical bottom woods 22 are parallel to the skid 1 and are limited and separated between the two skids 1. Take the L-shaped iron metal connector 3, and lock one side of its pressure plate to the vertical bottom wood 22 with fasteners (such as self-tapping screws). Align the slot 31 of the other side pressure plate with the two sides of the guide slot 11 and insert it. Rotate the L-shaped iron part 90 degrees to achieve pressing and locking.

[0021] To further enhance the chassis's load-bearing capacity, an iron plate reinforcement 4 is bolted to the through hole 12 on the side wall of the skid 1. Finally, a panel module 23 made of plywood is laid on top of the wooden component 2. When installing the end pieces 24 at both ends of the skid 1, nut blocks 27 are fixed on the slider plate 26 located in the guide slot 11. After moving it to the appropriate position, the end piece 24 is pressed against the end face of the panel module 23, so that the bolts pass through the through holes 25 on the end piece 24 and are locked with the nut blocks 27, thereby completing the assembly of the entire chassis.

[0022] During the box wall installation phase, hook assembly 5 is used for quick positioning. Hook assembly 5 is integrally formed from U-shaped support 51 and hanging body 52. ​​During installation, the hook at the end of hanging body 52 is engaged into the guide slot 11 of skid 1. At this time, the opening of U-shaped support 51 faces upward, used to support the bottom edge of the vertical box wall panel 6. To prevent the hook assembly 5 from shifting, the hook assembly 5 is secured to the skid 1 by a first screw through the side hole 53 on one side of U-shaped support 51. Subsequently, the vertical box wall panel 6 is placed into U-shaped support 51, and a second screw is passed through the side hole 53 on the other side of U-shaped support 51 to lock the vertical box wall panel 6 and hook assembly 5 together, effectively preventing the box wall from tipping over.

[0023] Example 2: like Figure 8 As shown, in this embodiment, when the equipment needs to be loaded into a shipping container, the pad 8 in Embodiment 1 needs to be replaced with the auxiliary skid 7, and the locking steps in Embodiment 1 are repeated to lock the auxiliary skid 7 to the bottom of the skid 1 through the through hole 13. The height of the auxiliary skid 7 matches the groove of the internal slide rail of the container, so that the resistance is smaller when pushing the container.

[0024] Example 3: A method for packing a recyclable iron-wood combination packaging chassis, based on the aforementioned recyclable iron-wood combination packaging chassis, includes the following in this embodiment: S1 Chassis Assembly: Select the spacing of skids 1 according to the width of the equipment, and choose bottom component pads 8 or auxiliary skids 7 according to the logistics plan. Adjust the arrangement density of the transverse top timbers 21 flexibly according to the position of the support points at the bottom of the equipment, and lock them to the skids 1 using metal connectors 3; S2 Laying and positioning: Lay panel modules 23 on wooden components 2, and adjust the position of end timbers 24 according to the outline of the equipment for limiting. Use lifting equipment to smoothly hoist the equipment onto panel modules 23, ensuring that the center of gravity of the equipment falls within the support range of the horizontal top timber 21. S3 Vertical wall enclosure: Install hook assembly 5 and vertical box wall panel 6 on both sides of skid 1 according to embodiment 1. Then, erect two sets of horizontal box wall panels 9 on skid 1 and fix them to the vertical box wall panel 6 with angle iron or bolts to form a closed box structure. S4 Top Cover Sealing and Non-destructive Disassembly: After sealing the top cover plate and securing it, the equipment arrives at its destination and the disassembly process is reversed: First, the top cover plate and the four sides of the box wall panels are removed; then, the bolts securing the end piece 24 are loosened, and the L-shaped metal connector 3 is removed (it can be disengaged from the guide slot 11 by rotating 90 degrees), and the wooden component 2 and panel module 23 are removed; finally, the bottom bolts are loosened, and the pad 8 or auxiliary skid 7 is separated. All metal parts (skid 1, connector 3, hook 5, etc.) are counted and stored in the warehouse for future reuse, achieving zero waste of packaging materials.
