[0002] The thermalization of three-dimensional electrode foil requires processes such as debinding and sintering. The control of the thermalization and sintering process plays a decisive role in the formation of pores. Once deformation, oxidation, uneven heating, foil roll damage and other problems occur during this process, it will not only affect the product quality, but also cause serious losses.
[0003] However, in the current existing technology, most foil rolls do not have an effective protective structure before heating, which makes it difficult to avoid deformation, oxidation, and uneven heating during the heating process, affecting product quality and production efficiency. Utility Model Content
[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose a foil wrapping protection structure for an electrode foil coil before heat treatment.
[0005] In order to achieve the purpose of innovation of this utility model, the following technical solutions can be used:

[0007] This protective structure is primarily used to reduce foil roll losses due to oxidation and deformation during the heating process, ensuring consistent foil roll performance and improving product quality. The rolled plain foil is tightly wrapped around the foil roll, preventing oxidation of the internal electrode foil. Furthermore, the tightening action of the peripheral screen further ensures that the foil roll does not deform significantly during the heating process. The screen is preferably made of durable stainless steel, which also provides excellent thermal conductivity for uniform heating of the foil roll. The mesh on the screen is breathable, ensuring efficient heat exchange while also maintaining the integrity of the foil roll. The screens are connected end to end to form a ring, and the connection between them is flexible and removable, making it convenient and practical.
[0008] In the above-mentioned foil wrapping protection structure of the electrode foil roll before heat treatment, the winding tension of the rolled plain foil is between 6-10 kg.

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0039] Specific implementation examples Figure 1-4 As shown, the foil wrapping protection structure of the electrode foil roll before heat treatment includes a rolled plain foil 2 wrapped around the outer periphery of the foil roll 1, the inner and outer ends of the rolled plain foil 2 are respectively bonded and fixed to the outer side wall of the foil roll 1 and the secondary outer circle of the rolled plain foil 2 by high-temperature resistant adhesive tape 4, and a screen 3 is tightly wrapped around the outer periphery of the rolled plain foil 2, and the head and tail ends of the screen 3 are fixedly connected by high-temperature resistant adhesive tape 4.
[0040] Specifically, this protective structure is primarily used to reduce losses in foil roll 1 due to oxidation and deformation during the heating process, ensuring consistent performance and improving product quality. The rolled plain foil 2 is tightly wrapped around the foil roll 1, preventing oxidation of the internal electrode foil. Furthermore, the tightening action of the peripheral screen 3 further ensures that the foil roll 1 does not deform significantly during the heating process. The screen 3 is preferably made of stainless steel, which is durable and strong, and its excellent thermal conductivity helps to evenly heat the foil roll 1. The mesh of the screen 3 is breathable, ensuring efficient heat exchange while also maintaining the integrity of the foil roll 1. The screen 3 is connected end to end to form a ring, and the connection between them is flexible and removable, making it convenient and practical.
[0041] In this embodiment, the winding tension of the rolled plain foil 2 is between 6-10 kg. The rolled plain foil 2 is about 50 m long, and its width is adapted to the axial length of the foil roll 1.
[0042] like Figure 1 、 3 As shown in Figures 4 and 5, annular smooth foil sheets 5 are installed at both ends of the foil roll 1. These sheets are evenly distributed with small holes and are secured to the foil roll 1 via plugs 6. The plugs 6 extend through the center hole 7 of the smooth foil 5, and their inner ends fit snugly into the axial hole 8 of the foil roll 1. The sidewalls of the plugs 6 include a circumferentially extending tapered surface 9 that is larger on the outside and smaller on the inside. The maximum outer diameter of the tapered surface 9 is larger than the inner diameter of the axial hole 8, while the minimum outer diameter is smaller. An axially extending extension ring 10 is installed inside the center hole 7 and inserted into the axial hole 8. The outer diameter of the extension ring 10 matches the inner diameter of the axial hole 8. The outer side of the smooth foil 5 is bonded to the side of the screen 3 with high-temperature-resistant tape 4.
[0043] Specifically, the smooth foil 5 at the end of the foil roll 1 is circular and conforms to the end face of the foil roll 1, effectively preventing excessive oxidation at the edges of the foil roll 1. The foil roll 1 consists of an inner core and a foil strip wound around it. The inner core is tubular and has an axial hole 8 extending axially through it. The plug 6 is generally shaped with one end larger than the other. The smaller end passes through the smooth foil 5 and is inserted into the axial hole 8, while the larger end presses the smooth foil 5 against the end face of the foil roll 1, providing flexible removability. The plug 6 is made of stainless steel, making it durable and suitable for high-temperature thermal environments. An extension ring 10 extends axially around the periphery of the center hole 7 and is inserted into the axial hole 8. This extension ring 10 not only provides a positioning function but also provides enhanced oxidation protection for the area between the axial hole 8 and the end face of the foil roll 1. The small holes in the smooth foil 5 ensure proper debinding and heat exchange within the foil roll 1.
[0044] Specific working principle: Before the three-dimensional electrode foil roll 1 is heated, the head of the rolled plain foil 2 is first fixed to the foil roll 1 through the high-temperature resistant tape 4, and the rolled plain foil 2 is tightly wound on the foil roll 1. After the winding is completed, the tail is fixed to the secondary inner circle through the high-temperature resistant tape 4; then the screen 3 is wrapped around the outer periphery of the rolled plain foil 2, and the head and tail ends are fixed with high-temperature resistant tape 4; finally, the extension ring 10 of the plain foil 5 is aligned with the axial hole 8 and covered on the end of the foil roll 1, the stainless steel plug 6 is plugged and fixed, and the high-temperature resistant tape 4 is set on the outer periphery of the plain foil 5, and the high-temperature resistant tape 4 is pasted on the screen 3 at the same time to complete the installation.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
