[0001] This utility model belongs to the field of transport packaging technology, specifically relating to a compact packaging structure for multiple laser devices. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] With the changing global economic environment, the demand for laser cutting machines is increasing. However, laser cutting machines are typically large and complex, presenting numerous challenges when loading them into containers. These challenges include low space utilization, cumbersome loading and unloading processes that can easily damage the equipment, and the need to disassemble a large number of parts before containerization. Currently, the most common transportation method is to load single units or a small number of units into containers, which is inefficient, costly, and requires disassembling and packaging a large number of parts separately. Furthermore, the equipment cannot be used immediately upon arrival at the customer's site, failing to meet the market demands for large-scale production and rapid delivery. Utility Model Content

[0004] The purpose of this invention is to provide a compact packaging structure for multiple laser devices, which can at least solve one of the above-mentioned technical problems.

[0005] To achieve the above objectives, embodiments of this utility model provide a compact packaging structure for multiple laser cutting machines, including a multi-layer support frame adapted to the internal dimensions of a container and fastening components. The support frame consists of multiple sets of crisscrossing support beams, and a support base is fixedly connected to the bottom of the support frame. The fastening components include auxiliary supports, adjustable fastening straps, and auxiliary feet. The auxiliary feet are set on the support base to stabilize the bottom laser cutting machines. The auxiliary supports connect the laser cutting machines between adjacent layers within the support frame. The two ends of the adjustable fastening straps are respectively connected to the laser cutting machines and the support base or support beams, and the fastening force is changed by adjusting the length of the adjustable fastening straps.

[0006] Furthermore, at least two sets of auxiliary supports are provided, with the upper end of the auxiliary support fixed to the anchor bolts of the upper laser cutting machine and the lower end fixed to the bed bolts of the lower laser cutting machine.

[0007] Furthermore, the auxiliary support is provided with elongated holes for adjusting the position of bolts, so that the equipment does not need to be moved to align with the holes when stacking, and the auxiliary support is fixed to the equipment from both the top and bottom.

[0008] Furthermore, auxiliary supports are installed between two adjacent laser cutting machines, respectively on both sides of the laser cutting machine.

[0009] Furthermore, the support beams are arranged in a crisscross pattern to form a grid-like support structure for positioning the laser cutting machine.

[0010] Furthermore, the adjustable fastening band is made of high-strength nylon and is equipped with adjustment components to adjust the fastening force according to the size of the laser cutting machine.

[0011] Furthermore, both the support beam and the support base are equipped with fasteners that connect to the adjustable fastening straps.

[0012] Furthermore, the fastener is welded to the support beam and the support base.

[0013] Furthermore, the auxiliary feet are made of metal and are welded and fixed to the supporting base.

[0014] Furthermore, the support base is connected to the bottom of the support frame by bolts.

[0015] The beneficial effects of the above technical solutions are as follows: This invention utilizes a multi-layered support frame and fastening components adapted to the size of a container to enable compact stacking of multiple laser devices without disassembly, solving the problem of low space utilization in traditional single-unit transportation. The grid-like support beams precisely position the equipment, and the auxiliary feet and adjustable fastening straps form a three-dimensional constraint to prevent damage from shaking during transportation.

[0016] The auxiliary support achieves quick alignment through elongated holes, with anchor bolts at the top and bottom connecting to bed bolts respectively. Symmetrical arrangement on both sides forms a rigid connection, eliminating the need for parts disassembly and improving inter-layer stability. The longitudinal and transverse support beam grid structure matches the equipment base, ensuring stacking accuracy.

[0019] In the diagram, 1 is the auxiliary support; 2 is the support base; 3 is the fixing component; and 4 is the auxiliary foot. Detailed Implementation

[0020] like Figures 1 to 6 As shown, this embodiment provides a compact packaging structure for multiple laser devices, including a multi-layer support frame adapted to the internal dimensions of a container and fastening components. The support frame consists of multiple sets of crisscrossing support beams, and a support base 2 is fixedly connected to the bottom of the support frame. The fastening components include auxiliary supports 1, adjustable fastening straps, and auxiliary feet 4. The auxiliary feet 4 are set on the support base 2 to stabilize the bottom laser cutting machine. The auxiliary supports 1 connect the laser cutting machines between adjacent layers within the support frame. The two ends of the adjustable fastening straps are respectively connected to the laser cutting machine and the support base 2 or the laser cutting machine and the support beams. The fastening force can be changed by adjusting the length of the adjustable fastening straps.

[0021] Specifically, the multi-layered support frame is designed according to the internal dimensions of the container. The grid structure formed by the support beams of each layer corresponds to the dimensions of the equipment base, achieving precise positioning. During loading, the bottom layer equipment is fixed to the support base 2 via auxiliary feet 4, the middle layer equipment is rigidly connected to the lower layer equipment via auxiliary supports 1, and the top layer equipment is connected to the support beams via adjustable fastening straps. During transportation, the support frame bears the main vertical load, the auxiliary supports 1 provide interlayer shear resistance, and the adjustable fastening straps absorb lateral vibration energy, forming a three-dimensional constraint system. Each layer of equipment is connected to the support structure through its own mounting holes, allowing for fixation without disassembling the main components.

[0022] like Figure 1 As shown, at least two sets of auxiliary supports 1 are provided. The upper end of the auxiliary support 1 is fixed to the anchor bolts of the upper laser cutting machine, and the lower end is fixed to the bed bolts of the lower laser cutting machine.

[0023] Specifically, two or more sets of auxiliary supports 1 are symmetrically arranged between adjacent layers of equipment to form a spatial truss support system. The upper end of the auxiliary support 1 is connected to the mounting holes of the upper equipment via threaded fastening, directly utilizing the standardized interfaces pre-installed at the factory. The lower end of the auxiliary support 1 is connected to the process screw holes on the side of the lower equipment bed via lock nuts; these screw holes are typically located at the reinforcing ribs of the bed's cast base. Under transport vibration conditions, the auxiliary support 1 converts the relative motion between the upper and lower equipment into its own tensile or compressive deformation, absorbing energy through the elastic deformation of the metal material. Since the anchor bolts and bed bolts are located in different mechanical load-bearing areas of the equipment, the vibration energy is decomposed into two independent force transmission paths: the main structure of the equipment and the mounting base, effectively suppressing resonance.

[0024] like Figure 2 As shown, the auxiliary support 1 has an elongated hole for adjusting the position of the bolt, which makes it convenient to stack the equipment without deliberately moving it to align with the hole. The auxiliary support 1 is fixed to the equipment from both the top and bottom.

[0025] During transportation, auxiliary support 1 forms a symmetrical constraint structure through two or more sets of distribution. When the anchor bolts of the upper laser cutting machine are locked to the upper end of auxiliary support 1, its gravity load is directly transferred to auxiliary support 1 through the anchor bolts; when the bed bolts of the lower laser cutting machine are locked to the lower end of auxiliary support 1, the rigid parts of the main frame of the equipment bear the reaction force from auxiliary support 1. By connecting the fixing points of different equipment at the upper and lower ends respectively, a bidirectional load transfer path is formed, limiting longitudinal displacement and lateral sway. The anchor bolts are part of the original installation structure of the equipment and can be connected without additional disassembly, while the area where the bed bolts are located has high structural strength, which can avoid local deformation.

[0026] like Figure 1 As shown, auxiliary supports 1 are installed between two adjacent laser cutting machines, respectively on both sides of the laser cutting machine. When the two machines are placed vertically side by side, the upper end of the auxiliary support 1 is connected to the anchor bolts of the upper machine, and the lower end is connected to the bed of the lower machine, forming a rigid connection channel through the two machines. The symmetrically arranged support rods on both sides form a triangular stable structure in the transverse direction of the equipment. When transverse vibration occurs during transportation, the supports on both sides simultaneously bear the shear force and convert it into axial tension, which is offset by the tensile strength of the metal rods to counteract the displacement trend. At the same time, the symmetrical layout ensures that the constraint force on both sides of the equipment is evenly distributed, avoiding the torque effect caused by unilateral force and preventing the equipment from tilting or torsional deformation. The support beams are arranged in a crisscross pattern to form a grid-like support structure for positioning the laser cutting machine. The intersecting support beams create continuous grid lines on the horizontal plane, confining the laser cutting machine within individual grid cells. When the equipment is placed, the edges of its base contact and limit movement with the grid beams; the longitudinal beams prevent forward and backward movement, while the transverse beams restrict lateral movement. The grid cell size is slightly larger than the equipment base size, and cushioning material is filled between the equipment base and the beams to create double fixation.

[0027] The adjustable fastening strap is made of high-strength nylon and features an adjustment mechanism to adjust the fastening force according to the size of the laser cutting machine. When the laser cutting machine is placed on the support frame, the adjustable fastening strap is adjusted to a constraint length that matches the shape of the equipment, forming a closed-loop structure around the machine. The tensile strength of the high-strength nylon material prevents strap deformation due to inertia during transportation, and the segmented locking function of the adjustment mechanism allows operators to precisely control the strap tension according to differences in equipment dimensions. This structure, through the synergy of the material's mechanical properties and the mechanical adjustment function, creates a dynamically balanced constraint system between the equipment and the support frame.

[0028] like Figure 3 and Figure 4 As shown, both the support beam and the support base 2 are equipped with fasteners 3 that connect to the adjustable fastening straps. After the adjustable fastening straps pass through the lifting holes of the laser cutting machine, their two ends connect to the fasteners 3 on the support beam and the support base 2, respectively. The fasteners 3 on the support beam convert the tension of the fastening straps into an overall constraint force on the frame structure, distributing the force throughout the frame through the crisscrossing support beams. The fasteners 3 on the support base 2 rigidly anchor the bottom of the equipment to the load-bearing platform, preventing horizontal slippage during transportation. This dual-fixing mechanism, through the synergistic effect of the three-dimensional frame of the support beam and the planar load-bearing surface of the support base 2, forms a three-dimensional constraint system, effectively eliminating localized stress concentrations caused by uneven surfaces of the support structure in traditional binding methods.

[0029] like Figure 5 As shown, the fastener 3 is welded to the support beam and the support base 2. The fastener 3 is welded to predetermined positions on the support beam and the support base 2, so that both ends of the adjustable fastening band are rigidly connected to the support structure via the fastener 3. During welding, the base of the fastener 3 completely melts and solidifies with the contact surface of the support beam or support base 2, eliminating the risk of connection failure caused by thread clearance or preload decay in traditional bolt connections. This permanent bond ensures the overall structural stability of the support frame and fastening components during transportation when subjected to vibration or impact, preventing equipment displacement or collision due to loose connections. like Figure 6As shown, the auxiliary foot 4 is made of metal and is welded to the support base 2. Utilizing the high elastic modulus of the metal material, the auxiliary foot 4 maintains geometric stability under the weight of the laser cutting machine and transportation vibrations, preventing plastic deformation that could lead to fixation failure. The welded connection eliminates the assembly gaps present in traditional bolted connections. During sudden braking or bumpy conditions of the container, there will be no relative displacement between the auxiliary foot 4 and the support base 2, thus blocking the transmission path of shaking from the underlying equipment. The combination of the metal material and the welding process gives the auxiliary foot 4 both structural strength to resist high-frequency vibrations and an irreversible physical locking relationship.

[0030] The support base 2 is bolted to the bottom of the support frame. During container transport, the support frame aligns with the threaded holes of the support base 2 through its bottom through-holes, and then the bolts are sequentially passed through the through-holes and screwed into the threaded holes to complete the fixation. The axial preload generated by the thread engagement creates a rigid connection between the support frame and the base, bearing the vertical load generated by equipment stacking. When the equipment layout needs to be adjusted, the connection can be released by loosening the bolts, and the support base 2 can be repositioned and then tightened again. This connection method maintains the structural integrity during transportation, and allows for layered loading and unloading of equipment by removing the bolts during loading and unloading, avoiding structural damage caused by cutting weld points.

[0031] The working principle of this utility model: The multi-layered support frame is designed according to the internal dimensions of the container. Intersecting support beams form a grid-like positioning structure. The bottom laser cutting machine is welded and fixed to the support base 2 via metal auxiliary feet 4. The middle layer equipment achieves rigid inter-layer connection through symmetrically arranged auxiliary supports 1 on both sides—the upper end of the auxiliary support 1 is fixed to the upper layer equipment's foot bolts, and the lower end is bolted to the lower layer equipment's bed. The elongated hole design allows for stacking without precise hole alignment. During transportation, the support frame bears vertical loads. The auxiliary supports 1 convert the relative motion of the upper and lower layers of equipment into their own elastic deformation to absorb vibration energy. Adjustable fastening straps form a closed-loop constraint with the frame fixing parts 3 via high-strength nylon straps. The adjustment parts dynamically adjust the tension according to the equipment size to absorb lateral impacts. The support base 2 is bolted to the frame to ensure overall rigidity. The welded auxiliary feet 4 and fastening strap fixing parts 3 eliminate connection gaps. Finally, through a three-dimensional constraint system, multiple pieces of equipment can be compactly stacked without disassembly, improving container space utilization and preventing transportation damage.

[0032] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
