Description

Technical Field

[0001] This utility model relates to the field of copper foil roll packaging technology, specifically a copper foil packaging body that can prevent end face oxidation. Background Technology

[0002] After electrolytic copper foil is produced, it is typically wound onto a core to form copper foil rolls for storage and transportation. In existing technologies, conventional packaging of copper foil rolls (such as sealing them with pearl cotton or stretch film and then placing them in wooden crates) mainly provides physical protection and basic dust and moisture prevention. However, during long-distance transportation or long-term storage, fluctuations in ambient temperature and humidity are inevitable, causing condensation of water vapor within the packaging cavity. This water vapor easily adheres to the exposed ends of the copper foil, significantly increasing the risk of oxidation, oxidation spots, and even discoloration, severely impacting the quality and yield of the final product.

[0003] Currently, there is no dedicated packaging solution in the industry for efficient anti-oxidation treatment of the copper foil end face. Usually, the only way to alleviate the problem is to improve the overall storage environment, which is costly and has limited effect, and is not suitable for transportation.

[0004] Therefore, in order to correct the above-mentioned defects, we propose a copper foil package that can prevent end face oxidation. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a copper foil packaging body that can prevent end face oxidation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper foil packaging body that can prevent end-face oxidation, including a copper foil winding core, with copper foil wound on the copper foil winding core, and a sealing packaging film, the sealing packaging film wrapping the copper foil roll wound on the copper foil winding core, and the sealing packaging film also wrapping the axial ends of the copper foil winding core extending from the copper foil roll, with desiccant strips respectively provided at the axial ends of the copper foil winding core, the sealing packaging film forming a packaging space, the desiccant strips being located in the packaging space, and the desiccant strips being installed on the sealing packaging film or the copper foil winding core through an installation structure.

[0007] Furthermore, the installation structure is a double-sided adhesive, and the desiccant strip is directly adhered to the sealed packaging film via the double-sided adhesive.

[0008] Furthermore, the mounting structure is a shape memory metal ring, and the desiccant strip is bonded to the shape memory metal ring with double-sided adhesive. The shape memory metal ring is fitted onto the copper foil winding core.

[0009] Furthermore, the desiccant strip has a length of 14cm to 18cm and a width of 2cm to 4cm.

[0010] Furthermore, the desiccant strip is one of silica gel desiccant, calcium chloride desiccant, or quicklime desiccant.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this device uses a sealed packaging film and desiccant strips to package the copper foil roll. The desiccant strips are located at both ends of the copper foil roll, so that both ends of the copper foil roll are always kept dry, avoiding oxidation and oxidation spots on the copper foil end face, and preventing the product quality and pass rate from declining due to oxidation.

[0013] 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.

[0014] This utility model provides a technical solution: like Figure 1-3 As shown, a copper foil packaging body that can prevent end-face oxidation includes a copper foil winding core 1, on which copper foil is wound. It also includes a sealing film 2, which wraps the copper foil roll wound on the copper foil winding core 1 and simultaneously wraps the axial ends of the copper foil winding core 1 extending from the copper foil roll. Desiccant strips 3 are respectively provided at both axial ends of the copper foil winding core 1. The sealing film 2 forms a packaging space, within which the desiccant strips 3 are located. The desiccant strips 3 are installed on the sealing film 2 or the copper foil winding core 1 via an installation structure. The desiccant strips 3 are positioned at both ends of the copper foil roll, ensuring that both ends of the copper foil roll remain dry, preventing oxidation and oxidation spots on the copper foil end face, and preventing a decline in product quality and yield due to oxidation.

[0015] The desiccant strip 3 is one of silica gel desiccant, calcium chloride desiccant, or quicklime desiccant, with silica gel desiccant being preferred as it has a better drying effect and does not produce foreign matter. The length of the desiccant strip 3 is 14cm to 18cm and the width is 2cm to 4cm, preferably about 16cm in length and about 3cm in width.

[0016] Example 1 The installation structure uses double-sided adhesive, and the desiccant strip 3 is directly adhered to the sealed packaging film 2 via the double-sided adhesive.

[0017] Example 2 The installation structure is a memory metal ring 4. The desiccant strip 3 is bonded to the memory metal ring 4 with double-sided adhesive. The memory metal ring 4 is fitted onto the copper foil winding tube core 1. The memory metal ring 4 is the same as the slap rings and pat rings on the market. It is mainly composed of memory material and polyester fiber wrapped around the memory material. The memory material is supported by an elastic memory spring sheet with cold-rolled steel or stainless steel. Initially, the shape memory metal ring 4 is straight. When sealing the packaging, the shape memory metal ring 4 is patted onto the copper foil winding core 1, and the shape memory metal ring 4 will then be wound onto the copper foil winding core 1. This installation structure makes it easy to remove the desiccant strip 3 from the copper foil winding core 1 for separate recycling when unpacking later. At the same time, the desiccant strip 3 can be pre-attached to the shape memory metal ring 4 with double-sided adhesive, so that the desiccant can be quickly placed in when sealing the packaging.

[0018] 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.
