Description

Technical Field

[0001] This utility model relates to the field of roll product packaging, specifically to a packaging structure for roll products. Background Technology

[0002] Currently, the common packaging method for film rolls and other roll products is to wrap stretch film around both ends of the roll, which effectively prevents the roll from unraveling. This packaging method is simple and quick, but it has revealed many problems in practical applications. For example, stretch film has poor abrasion resistance and is easily damaged by friction during transportation and storage, causing the roll to unravel. This not only affects the appearance quality of the roll but may also have an adverse effect on its performance.

[0003] Therefore, there is a need to provide a packaging structure for roll products to replace the above-mentioned packaging methods, so as to improve the protection of roll products and prevent the appearance quality and performance of roll products from being affected. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides a packaging structure for roll products, and at least solves the technical problem of how to improve the protection of roll products.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a packaging structure for a roll product, the roll product being cylindrical, the packaging structure comprising two corrugated cardboard sheets, the corrugated cardboard sheets comprising:

[0008] The main board has the same shape and area as the end face of the roll product and is used to attach to the end face of the roll product.

[0009] Several side plates are arranged in a ring and integrally connected to the circular periphery of the main board;

[0010] In this process, when a corrugated cardboard is folded into shape, each side panel is bent towards the same surface of the main board and connected sequentially around the main board to form a ring-shaped wrapping part. The wrapping parts of the two corrugated cardboard sheets are respectively wrapped around the outer peripheral walls of both ends of the roll product.

[0011] Furthermore, the packaging structure of the roll product also includes a wrapping layer, which is wrapped around the outside of the packaged part after the corrugated cardboard is folded and formed to wrap the roll product.

[0012] Further, the aforementioned wrapping layer includes, but is not limited to, one or a combination of PE wrapping film, PP strapping, and PP cable ties.

[0013] Furthermore, the size of the aforementioned wrapping portion is no greater than half the size of the roll product along its axial direction.

[0014] Furthermore, when the aforementioned corrugated cardboard is folded into shape, the two wrapping sections are seamlessly joined.

[0015] Furthermore, the packaging structure of the roll product also includes a sealing layer, which covers the outside of the roll product and is located inside the packaged portion.

[0016] Furthermore, the aforementioned roll product has a mounting hole on its axis, and the main board has a clearance hole that is opposite to and communicates with the mounting hole. The diameter of the clearance hole is not less than the diameter of the mounting hole.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the packaging structure for roll products provided by this utility model has the following beneficial effects:

[0019] The packaging structure for roll products provided by this utility model involves first placing the main board of a corrugated cardboard against one end of the roll product, then folding the side panels of the corrugated cardboard so that each side panel is sequentially connected around the main board to form a wrapping section to wrap that end of the roll product. Then, the above steps are repeated to fold another corrugated cardboard, wrapping it around the other end of the roll product, thus completing the packaging. It can be seen that this packaging structure for roll products completes the packaging of the roll product by folding and wrapping two corrugated cardboard sheets around both ends of the roll product, replacing stretch film. The corrugated cardboard has significantly better abrasion resistance than stretch film, effectively improving the protection of the roll product and preventing it from unraveling during packaging, transportation, and storage, thus avoiding any impact on the appearance quality and performance of the roll product.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a packaging structure for roll products, which solves the problem of how to improve the protection of roll products 1.

[0032] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a perspective view of the folding and forming of the packaging structure of the roll product in the embodiment. Figure 2 This is a three-dimensional view of the packaging structure of the roll product in the embodiment, laid flat. Figure 3 The image shown is a perspective view of the folding process of the packaging structure of the roll product in the embodiment. The packaging structure of the roll product includes two corrugated cardboard sheets 2, and the corrugated cardboard sheets 2 include a main board 3 and several side panels 4.

[0033] The roll product 1 is cylindrical, and the shape of the main board 3 is consistent with the shape of the end face of the roll product 1. The area of ​​the main board 3 is consistent with the area of ​​the end face of the roll product 1. The main board 3 is used to adhere to the end face of the roll product 1.

[0034] Each side plate 4 is arranged in a ring around the main board 3 and is integrally connected to the periphery of the main board 3.

[0035] When a corrugated cardboard 2 is folded, each side plate 4 is bent toward the same surface of the main board 3 and connected in sequence around the main board 3 to form a ring-shaped wrapping part 5. The wrapping parts 5 of the two corrugated cardboard 2 are respectively wrapped around the outer peripheral walls of both ends of the roll product 1.

[0036] The above technical solutions provide packaging structures for roll products, such as... Figure 2 As shown, first, place the main board 3 of a corrugated cardboard 2 against one end face of the roll product 1; then, as... Figure 3As shown, the side panels 4 of the corrugated cardboard 2 are folded over so that the side panels 4 are sequentially connected around the main board 3 to form a wrapping section 5, which wraps the end of the roll product 1, as shown. Figure 1 As shown; repeat the above steps, fold another corrugated cardboard 2 so that it wraps around the other end of the roll product 1, thus completing the packaging of the roll product 1. It can be seen that this packaging structure of the roll product completes the packaging of the roll product 1 by folding and wrapping two corrugated cardboard 2 around both ends of the roll product 1, replacing stretch film. The corrugated cardboard 2 has significantly better abrasion resistance than stretch film, effectively improving the protection of the roll product 1 and preventing it from unraveling during packaging, transportation, and storage, thus avoiding any impact on the appearance quality and performance of the roll product 1.

[0037] The aforementioned side panels 4 are joined together in sequence and then fixed by adhesive extension plates or by wrapping, thereby maintaining the corrugated cardboard 2 in its formed state. Furthermore, there can be a small gap between adjacent side panels 4 of the same corrugated cardboard 2 to facilitate folding of the side panels 4, prevent adjacent side panels 4 from overlapping and affecting the packaging appearance, and also allow for seamless connection.

[0038] See Figure 1 and Figure 4 As shown, Figure 4 This is a perspective view of the packaging structure with the winding layer 6 in the embodiment. The packaging structure of the roll product also includes the winding layer 6, which surrounds the outside of the wrapping part 5 after the corrugated cardboard 2 is folded and formed and wraps the roll product 1. In this way, the winding layer 6 makes the side panels 4 contact the outer peripheral wall of the roll product 1 by winding and fixing, and keeps the corrugated cardboard 2 in its formed state. This can improve the structural strength and structural stability of the connection between adjacent side panels 4, thereby further enhancing the stability of the packaging, making the connection between adjacent side panels 4 less prone to cracking, and replacing adhesive. It is not only convenient for disassembly and assembly, and switching between the unfolded and formed states of the corrugated cardboard 2, but also convenient for recycling and reuse of the corrugated cardboard 2, which meets environmental protection requirements.

[0039] Based on the above embodiments, the wrapping layer 6 includes, but is not limited to, one or a combination of PE stretch film, PP strapping, and PP cable ties. PE stretch film has good tensile strength, flexibility, and self-adhesion, allowing it to adhere tightly to the outside of the wrapping portion 5, resulting in a larger packaging area. PP strapping has high strength and abrasion resistance, further enhancing the packaging's binding force and preventing it from unraveling during handling. PP cable ties are easier to handle, quickly securing the side panels 4, and their binding force is greater than that of PE stretch film but less than that of PP strapping. It can be seen that PE stretch film, PP strapping, and PP cable ties all enhance the stability of the packaging. Furthermore, PE stretch film, PP strapping, and PP cable ties can be used individually or in combination. For example, adding PP strapping or PP cable ties outside the PE stretch film creates a wrapping layer 6 that combines the effects of both PE stretch film and PP strapping (or PP cable ties). Thus, the effects of one or more of these three materials, when used individually or in combination, result in different effects for the wrapping layer 6. Different packaging needs and cost considerations can be accommodated by selecting one or more of these materials for individual use.

[0040] In one embodiment of the wrapping section 5, the size of the wrapping section 5 is no greater than half the size of the roll product 1 in the axial direction. This prevents the two wrapping sections 5 from overlapping after the corrugated cardboard 2 is folded, which would result in gaps between adjacent side panels 4 of the same corrugated cardboard 2, affecting the packaging effect and appearance quality.

[0041] See Figure 5 As shown, Figure 5 This is a perspective view showing the seamless connection of the two wrapping parts 5 in the embodiment. Based on the above embodiment, when the corrugated cardboard 2 is folded and formed, the two wrapping parts 5 are seamlessly connected. In this way, the combination of the two wrapping parts 5 can protect the entire outer peripheral wall of the roll product 1 from being exposed to the external environment, effectively preventing problems such as dirt and wear on the outer peripheral wall of the roll product 1, and further improving the protection of the roll product 1.

[0042] See Figure 5 As shown, based on the above embodiments, the packaging structure of the roll product further includes a sealing layer 7, which covers the outside of the roll product 1 and is located inside the wrapping part 5. Thus, the sealing layer 7 can seal the roll product 1, providing waterproof and dustproof protection. Combined with the two seamlessly connected wrapping parts 5, it effectively improves the sealing performance of the packaging, thereby further enhancing the protection of the roll product 1.

[0043] See Figure 1As shown, in one embodiment of the main board 3, a mounting hole 11 is formed on the axis of the roll product 1. The main board 3 has a clearance hole 31 that is opposite to and communicates with the mounting hole 11. The diameter of the clearance hole 31 is not smaller than the diameter of the mounting hole 11. Thus, the mounting hole 11 facilitates the hoisting and transport of the roll product 1, or the installation of the roll product 1 onto the roller of a machine tool. The clearance hole 31 ensures that the mounting hole 11 is fully exposed, allowing the roll product 1 to be transported or installed without disassembling the packaging. The packaging is only removed when the roll product 1 is needed. This effectively prevents the roll product 1 from unraveling during transport or installation, thus avoiding its subsequent use.

[0044] The aforementioned sealing layer 7 can be formed using existing plastic bags or plastic films, which is low-cost and convenient for packaging. Furthermore, plastic bags or films are easily torn, so they will not affect workers' ability to transport or install the roll product 1 without disassembling the packaging. Alternatively, the sealing layer 7 can be coated with a waterproof material onto the inner surfaces of the main board 3 and side panels 4. In this way, after the corrugated cardboard 2 is folded, the sealing layer 7 can automatically cover the outside of the roll product 1, improving the sealing of the packaging. During disassembly, the sealing layer 7 can be automatically removed, which is very convenient.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
