Description

Technical Field

[0001] This utility model relates to an aluminum sheet coil structure. Background Technology

[0002] In existing technologies, the main method for fixing aluminum sheet coils is to bind them with woven bags. The woven bags pass through the inner wall of the aluminum sheet coil, the end face of the aluminum sheet coil, and the end position of the aluminum sheet coil, such as CN215096170U designed by the applicant. However, this simple fixing structure is prone to causing the aluminum sheet coil to expand and break the woven strap, which poses a hidden danger to installation. In view of this, this invention is hereby applied for. Utility Model Content

The end caps are fixed to the aluminum sheet coil body by an outer binding strap, and an anodized film is disposed on the surface of the aluminum sheet coil.

[0005] Furthermore, the thickness of the anodic oxide film is 5–15 μm.

[0006] Furthermore, the cardboard includes a double-layer corrugated paper layer, with an elastic polyurethane coating between adjacent corrugated paper layers, and a PE film on its surface.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] like Figure 1-5 As shown, this utility model relates to an aluminum coil structure, including an aluminum coil body 1 and end caps 4 disposed at both ends of the aluminum coil. An inner cylinder 5 is disposed in the middle of the aluminum coil body, and an inner binding strap 21 is disposed on the inner cylinder. The inner binding strap is tightly attached to the inner wall of the inner cylinder and the ends of the aluminum coil. A cardboard 3 is disposed where the inner binding strap contacts the edges of the aluminum coil. The cardboard has a 90° corner structure at the contact point with the edges of the aluminum coil. This design allows the cardboard to better fit the edges of the aluminum coil, protecting the edges from being damaged by the binding strap during the binding process, and also enhancing the friction between the binding strap and the aluminum coil, improving the stability of the binding. The end caps are fixed to the aluminum coil body by an outer binding strap 2, and an anodized film is disposed on the surface of the aluminum coil.

[0020] Furthermore, the thickness of the anodic oxide film is 5–15 μm. This oxide film can improve the corrosion resistance and wear resistance of the aluminum coil, extending its service life. The anodic oxide film is a dense oxide layer formed on the surface of the aluminum coil through an anodizing process. During transportation or stacking, the aluminum coil may come into contact with various corrosive substances, such as humid air and chemical gases. The anodic oxide film can effectively isolate the aluminum coil from contact with these corrosive substances, thereby improving the corrosion resistance of the aluminum coil. At the same time, during handling, the surface of the aluminum coil may rub against other objects. The anodic oxide film has high hardness and can resist a certain degree of wear, extending the service life of the aluminum coil.

[0021] Furthermore, the cardboard includes a double-layer corrugated paper layer 11, with an elastic polyurethane coating 12, 0.1mm-0.3mm thick, between adjacent corrugated paper layers. A PE film 13 is applied to the surface of this coating. This structure increases the cardboard's abrasion resistance. The double-layer corrugated paper provides cushioning and support, the elastic polyurethane coating increases abrasion resistance and elasticity, and the PE film provides waterproof and moisture-proof protection. The double-layer corrugated paper has good cushioning properties; when the aluminum roll is subjected to external impact, the corrugated paper layer can absorb some energy, reducing damage to the aluminum roll. The elastic polyurethane coating, with a thickness between 0.1mm and 0.3mm, not only increases the cardboard's abrasion resistance but also imparts a certain degree of elasticity. When the aluminum roll slightly expands or contracts due to factors such as temperature changes, the elastic polyurethane coating acts as a buffer, preventing excessive stress between the cardboard and the aluminum roll. The PE film provides waterproof and moisture-proof protection, preventing the aluminum roll from rusting in humid environments.

[0022] Furthermore, a perforation is provided in the middle of the end cap, and a tube 41 is installed at the perforation location, which is inserted into the inner cylinder. The end cap serves to seal both ends of the aluminum sheet coil, preventing it from loosening during transportation or stacking. The insertion of the tube into the inner cylinder increases the connection stability between the end cap and the main body of the aluminum sheet coil. The tube is fixed to the inner cylinder with bolts, and corresponding threaded holes are provided on the inner cylinder. To strengthen the fixation, anti-slip ridges are provided on the inner wall of the end cap. The anti-slip ridges increase the friction between the tube and the inner cylinder, preventing the tube from sliding inside the inner cylinder, and further improving the firmness of the connection between the end cap and the main body of the aluminum sheet coil.

[0023] Furthermore, the outer binding tape is tightly attached to the outer side of the aluminum sheet coil, the end cap, the tube, and the inner cylinder. The inner and outer binding tapes work together to firmly fix the aluminum sheet coil body, the end cap, and the inner cylinder together. The inner binding tape constrains the aluminum sheet coil from the inside, preventing it from expanding in the radial direction; the outer binding tape reinforces the entire structure from the outside, ensuring that there is no relative displacement between the components.

[0024] Furthermore, cardboard is provided where the outer binding strap contacts the corner of the aluminum plate roll.

[0025] Furthermore, the tube is fixed to the inner cylinder by bolts 6, and corresponding threaded holes 51 are provided on the inner cylinder. To strengthen the fixation, anti-slip ridges 42 are provided on the inner wall of the end cap.

[0026] In this design, the anodized film, cardboard, end caps and tubes, and inner and outer binding straps work together to stabilize the aluminum coil structure, facilitating transportation and stacking. The anodized film protects the surface of the aluminum coil, improving its durability and reducing damage caused by external environmental factors, ensuring good performance throughout its service life. The cardboard protects the edges of the aluminum coil and enhances the friction between the binding straps and the coil, allowing the inner and outer binding straps to better perform their fixing function. The end caps and tubes are tightly connected by bolts and anti-slip ridges, sealing both ends of the aluminum coil and preventing it from loosening. The inner and outer binding straps work together to constrain and reinforce the aluminum coil from both inside and outside, forming a stable whole structure. This synergistic effect effectively avoids the problem of the braided straps breaking due to expansion in existing technologies, improving the safety and stability of the aluminum coil during transportation and stacking.
