DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-13 A hollow plate buffer box structure and a preparation method thereof, comprising a box body hollow plate 1 and a box body 2 and nails 19 formed by the box body hollow plate 1, wherein the box body hollow plate 1 is an inner and outer double-wall hollow structure, the inner wall 11 of the box body hollow plate 1 is covered with arched grooves 111 in the depth direction, and the outer wall 12 of the box body hollow plate 1 is a plane. When the box body hollow plate 1 is processed and formed, the strength of the box body hollow plate 1 is increased by increasing the wall thickness of the inner wall 11 and the outer wall 12, which can replace the traditional complex packaging methods of wooden boxes, wooden frames, and wooden pallets, and bring convenience to the normal express logistics transportation packaging of super-heavy and super-large products.

[0038] The inner wall 11 of the box hollow plate 1 is divided into a plurality of main folds 112 by a crease line 13, and the two ends of the main fold 112 are divided into two secondary folds 113 by a crease line 13. The box hollow plate 1 is folded inwardly by the crease line 13 to form a box body 2, and the box body 2 is fixed with staples 19.

[0039] Compared with the packaging method of using packaging materials and cartons on the market, the box body 2 folded from the hollow board 1 of the box body greatly simplifies the packaging process. At the same time, it is moisture-proof, waterproof and mildew-proof. Compared with cartons, it has the advantage of good resistance to harsh environments, simplifies packaging, eliminates the use of environmentally unfriendly materials such as foam, and protects the environment. At the same time, it has good strength and can be used as a packaging box for heavy and large products. The strength is increased by increasing the wall thickness of the inner wall 11 and the outer wall 12. It can replace the traditional complex packaging methods of wooden boxes, wooden frames, and wooden pallets, and brings convenience to the normal express logistics transportation packaging of super-heavy and super-large products. It has a simple and compact structure, meets economic benefits, and has broad application prospects.

[0040] As a specific technical solution of this embodiment, the cross-section of the groove 111 is V-shaped, U-shaped or arc-shaped, and the groove 111 deepens in an arch shape in the depth direction, and the intersection of the grooves 111 is the deepest.

[0041] In this embodiment, the groove 111 divides the entire large area of ​​the wall into a large number of small units, thereby greatly increasing the wall strength. The cross-section of the groove 111 is one of V-shaped, U-shaped or arc-shaped. This design allows the groove 111 to support the cavity between the inner wall 11 and the outer wall 12.

[0042] As a specific technical solution of this embodiment, the intersection of two adjacent grooves 111 is the deepest and is connected to the outer wall 12 at the deepest point of the groove.

[0043] In this embodiment, this structural design enables multiple support points to be provided between the inner wall 11 and the outer wall 12. The intersections of numerous grooves 111 are connected into numerous support points to support the entire inner wall 11 and the outer wall 12, thereby strengthening the support between the inner wall 11 and the outer wall 12, greatly improving the cushioning performance of the hollow plate 1 of the box body, making it more impact-resistant and less likely to damage items protected inside the box body 2.

[0044] As a specific technical solution of the present embodiment, the positions corresponding to the main hinges 112 at both ends of the pre-connected hollow plate 1 of the box body are respectively provided with an extension plate 14 and a fixing hole 15, and the interior of the extension plate 14 is provided with a fixing hole 2 16 corresponding to the fixing hole 15; the positions corresponding to the auxiliary hinges 113 on the hollow plate 1 of the box body are respectively provided with corresponding fixing holes 3 17 and 4 18; it also includes a nail 19, one end of the nail 19 is provided with an inclined surface buckle 191, and a gap is provided in the middle of the shaft. When the nail 19 is pressed into the hole, the inclined surface is subjected to force and the inclined surface buckle 191 becomes smaller toward the inside of the shaft diameter. After it is fully pressed in, the external force on the inclined surface disappears, and the inclined surface buckle 191 pops open and locks to fix it. After the hollow plate 1 of the box body is folded into a box, the nails 19 are buckled in between the fixing hole 15 and the fixing hole 2 16 and between the fixing hole 3 17 and the fixing hole 4 18.

[0045] In this implementation plan, refer to Figure 7-12 When the hollow board 1 of the box body is folded into a box, there are four main hinges 112. The main hinges 112 at the head and tail ends of the hollow board 1 of the box body are connected, so that the four main hinges 112 are folded into the four sides of the box body 2, and the extension plate 14 on the main hinge 112 at the head end of the hollow board 1 of the box body is buckled into the inner side of the main hinge 112 at the tail end of the hollow board 1 of the box body, so that the second fixing hole 16 and the first fixing hole 15 are opposite to each other, and the nails 19 are buckled into the outside of the box body 2. The nails 19 pass through the first fixing hole 15 and the second fixing hole 16 and enter the inside of the box body 2 to complete the connection of the hollow board 1 of the box body, so that the box body 2 is initially formed. The hollow board 1 of the box body is made of tough plastic materials such as PE, PP, nylon, etc. The hollow board 1 of the box body is tough, so it has the property of being locally compressible.

[0046] After the hollow board 1 of the box body is folded into a box, the corresponding hole positions on the hollow board 1 of the box body are opposite to each other, and the hollow board 1 of the box body corresponding to the auxiliary hinge 113 is partially overlapped together. When the nail 19 is pressed into the second hollow board 1 through the first hollow board 1, the first hollow board 1 of the box body is partially flattened, and the expanded head of the nail 19 is compressed small and can pass through the fixing hole. When the nail 19 is pressed into the inside of the second hollow board 1 of the box body and then released, the first hollow board 1 of the box body rebounds, so that the inclined surface buckle 191 of the nail 19 is tightly buckled on the inner wall 11 of the second hollow board 1 of the box body, so that the two stacked hollow boards 1 of the box body can be firmly connected together. This connection method is simple and convenient. Because there is tension, the outer diameter of the inclined surface buckle 191 in the free state is larger than the aperture of the fixing hole. Not only is the connection firm but also it is not easy to fall off or be damaged. This connection method can be completed without the aid of other tools and has wide versatility and usability.

[0047] A method for preparing a hollow plate buffer box structure comprises the following steps:

[0048] S1. The hollow plate is processed and formed. The hollow plate 1 of the box body is formed by blow molding or rotational molding, and the wall surface is covered with arched grooves 111. The arched grooves 111 on the inner wall 11 strengthen the wall surface. The arched grooves 111 are arc-shapedly deepened toward the inside of the cavity until they intersect at the intersection. Many intersections support the entire inner and outer wall 12 structure. The arched structure not only enables the intersection to support the inner and outer walls, but also has a good buffering effect. The arched structure allows the blowing gas to pass through the arc-shaped cavity, so that good blow molding can be performed.

[0049] S2, hollow board cutting and forming, according to the unfolded size of the box 2, use laser cutting or cutting die to cut the required box hollow board 1 size, including fixing holes, including connection holes or hand-lifting holes required to be set up inside and outside the box 2;

[0050] S3, setting a crease line 13, using laser cutting to cut out the crease line 13 on the inner wall 11 that needs to be folded, or hot pressing a V-shaped crease line 13 on the inner wall 11 that needs to be folded;

[0051] S4, folding the box body hollow plate 1 into a box according to the crease line 13, folding inward along the crease line 13, and folding the box body hollow plate 1 into a box;

[0052] S5, sealing the box. After the hollow board 1 of the box body is folded into a box, the fixing hole 15 and the fixing hole 2 16 are positioned opposite to each other, and the fixing hole 3 17 and the fixing hole 4 18 are positioned opposite to each other. Finally, the nails 19 are buckled in to complete the fixing of the box body 2.

[0053] As a specific technical solution of this embodiment, the box body hollow plate 1 constituting the box body 2 can be obtained by connecting one whole piece end to end, or by connecting and fixing multiple separate pieces.

[0054] As a specific technical solution of this embodiment, in S3, the crease line 13 formed by laser cutting is a narrow stripe rectangular type or a dotted line type.

[0055] In this embodiment, the crease line 13 is cut by laser cutting or blade cutting, and the inner wall 11 at the place where folding is required is cut into a narrow rectangle or dotted line. The outer wall 12 is still retained without being damaged and the appearance is not affected. In this way, when the folding box is formed, the force hindering the folding at the hollowed-out inner wall 11 is minimal. The material of the outer wall 12 is PE, PP, nylon and other tough plastic materials, which can be bent. In this way, it can be conveniently folded into a box along the predetermined crease line 13. The crease line 13 of the inner wall 11 can also destroy the strength of the inner wall 11 in the crease line 13 area by pressure or hot pressing, so as to facilitate the folding into a box along the crease line 13.

[0056] As a specific technical solution of this embodiment, in S5, after the hollow board 1 of the box is folded into a box, in addition to the nails 19, the box 2 can also be fixed by using one or a combination of two or more of plastic expansion nails, Velcro, carton nails, glue, and high-temperature welding.

[0057] In this embodiment, after the head and tail ends of the hollow plate 1 of the box body are connected, the items that need to be protected can be loaded into the box body 2, and then the secondary fold 113 can be folded in half so that the fixing hole three 17 and the fixing hole four 18 are positioned opposite each other, and the staples 19 can be used to buckle into the fixing holes three 17 and the fixing holes four 18 to complete the sealing of the box. The box body 2 can also be sealed or reinforced for a second time by using one or a combination of two or more of Velcro, carton staples, glue, and high-temperature welding, which is more convenient to use.

[0058] To sum up, compared with the packaging method of using packaging auxiliary materials and cartons on the market, the hollow board buffer box structure and its preparation method use a box body 2 folded from a box hollow board 1, which greatly simplifies the packaging process. At the same time, it has the properties of moisture-proof, waterproof and mildew-proof. Compared with cartons, it has the advantage of good resistance to harsh environments, simplifies packaging, eliminates the use of environmentally unfriendly materials such as foam, and protects the environment. At the same time, it has good strength and can be used as a packaging box for heavy and large products. The strength is increased by increasing the wall thickness of the inner wall 11 and the outer wall 12. It can replace the traditional complex packaging methods of wooden boxes, wooden frames, and wooden pallets, and brings convenience to the normal express logistics transportation packaging of super-heavy and super-large products. The structure is simple and compact, in line with economic benefits, and has broad application prospects.
