[0019] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present utility model provides a cathode roller edge protection and O-ring embedding device, as Figures 1-4 shown. The cathode roller edge protection and O-ring embedding device includes: a cathode roller body 1; a limiting groove 2, the limiting groove 2 is provided on the circumferential surface of one end of the cathode roller body 1; two plastic protective layers 3, both of the two plastic protective layers 3 are provided on the two side walls in the limiting groove 2; a rubber sealing ring 4, the rubber sealing ring 4 is laid in the limiting groove 2, and both ends of the rubber sealing ring 4 are provided with adjustment openings; two meshing openings 5, the two meshing openings 5 are respectively provided on the two adjustment openings, and the two meshing openings 5 can be buckled with each other; a limiting component, the limiting component is provided on the rubber sealing ring 4, and the limiting component is used to close the adjustment openings.

[0021] In this embodiment, the cathode roller body 1 serves as the basis of the entire device, bearing the main electrolysis reaction during the production of electrolytic copper foil. Its huge size, weight, and titanium metal material reflect its importance, preciousness, and high value, and at the same time highlight the necessity of effectively protecting it. The limiting groove 2 provides an installation position for subsequent protective structures such as the plastic protective layer 3 and the rubber sealing ring 4. This design not only ensures the stability of the protection device but also facilitates subsequent maintenance and replacement. The plastic protective layer 3, as the first line of defense, can directly block the direct contact between corrosive liquids such as copper sulfate and the cathode roller body 1, reducing the corrosion effect. The rubber sealing ring 4 further enhances the sealing effect, effectively preventing the overflow of liquids such as copper sulfate to the edge of the cathode roller. The adjustment port design on it allows a certain degree of flexibility, facilitating installation and adjustment, while the meshing ports 5 on both sides can be buckled together when needed to close the adjustment port and ensure the sealing performance.

[0022] In a further preferred embodiment of the present utility model, the limiting component includes a clamping plate 6, a limiting shell 7, a bayonet 8, a cylinder 9, a spring 10, a limiting block 11, and a limiting rod 12. The clamping plate 6 and the limiting shell 7 are respectively fixed on two adjustment ports. The bayonet 8 is opened on the limiting shell 7. The clamping plate 6 is inserted into the bayonet 8. The cylinder 9 is fixed on one side of the limiting shell 7. One end of the spring 10 is installed on the inner wall of one end of the cylinder 9. The limiting block 11 is fixed on the other end of the spring 10. The limiting rod 12 is installed on the limiting block 11 and extends out from the other end of the cylinder. A limiting hole 13 is provided on the clamping plate 6, and the limiting rod 12 can extend into the limiting hole 13.

[0023] In this embodiment, the clamping plate 6 cooperates with the limiting shell 7 on the other side and realizes preliminary positioning and fixing by extending into the bayonet 8. The design of the clamping plate 6 makes the closing of the adjustment port more stable and not easily loosened due to external factors. The bayonet 8 provided on the limiting shell 7 provides an insertion space for the clamping plate 6. At the same time, the limiting shell 7 also bears subsequent components such as the cylinder 9 and is the support structure of the entire limiting component. The cylinder 9 provides an installation space for the spring 10 and ensures the normal expansion and contraction of the spring 10 under pressure through its structural stability. The elastic action of the spring 10 enables the limiting block 11 to displace when subjected to external force and automatically reset after the external force disappears, thereby ensuring the tight fit between the limiting rod 12 and the limiting hole 13. The limiting block 11 can drive the limiting rod 12 to perform telescopic movement under the action of the spring 10 to realize the locking and unlocking with the limiting hole 13.

[0024] In a further preferred embodiment of the present utility model, a limiting telescopic rod 15 is provided inside the spring 10. The limiting telescopic rod 15 is composed of an outer cylinder and an inner cylinder. The outer cylinder and the inner cylinder are respectively installed on the inner wall of the top of the cylinder 9 and the top of the limiting block 11. The outer cylinder is slidably sleeved outside the inner cylinder.

[0025] In this embodiment, the design of the limit telescopic rod 15 aims to improve the stability and guiding property of the spring 10 during the telescopic process, effectively preventing the spring 10 from being distorted or offset during the telescopic process, thereby improving the stability of the entire limit assembly.

[0026] In a further preferred embodiment of the present invention, a connecting rope 16 extending outside the cylinder body 9 is installed on the limit block 11. The connecting rope 16 can penetrate through the limit telescopic rod 15, and a pull ring 17 that can contact the outer wall of the top of the cylinder body 9 is installed on the connecting rope 16.

[0027] In this embodiment, the connecting rope 16 has a certain length and flexibility and can freely expand and contract with the up and down movement of the limit block 11. At the same time, the design of the connecting rope 16 enables the user to remotely operate the limit block 11 from outside the cylinder body 9. The pull ring 17 is used to provide an easy-to-grasp and operate handle. The pull ring 17 has a relatively large diameter and a smooth edge to ensure the comfort and safety of the user during the operation. Through the design of the pull ring 17 and the connecting rope 16, the user can easily move the limit block 11 up and down from outside the cylinder body 9 without directly contacting and disassembling other components. This remote operation method not only improves work efficiency but also reduces the operation difficulty and safety risk.

[0028] In a further preferred embodiment of the present invention, a pinch piece 14 is fixed on the clamping plate 6. The pinch piece 14 is provided with anti-slip lines. The connecting rope 16 is a soft steel wire rope, and the clamping plate 6 is in sliding contact with the inner wall of the bayonet 8.

[0029] In this embodiment, the pinch piece 14 provides an easy-to-operate handle for the user. The anti-slip lines provided on the pinch piece 14 can increase the friction and stability of the user during the operation, preventing accidental operations caused by slippery hands. The soft steel wire rope has higher strength, wear resistance, and corrosion resistance. In the harsh environment of electrolytic copper foil production, the soft steel wire rope can better withstand tension, wear, and corrosion, ensuring the long-term reliable use of the connecting rope 16.

[0030] In a further preferred embodiment of the present invention, the width of the rubber sealing ring 4 is longer than the width of the limit groove 2. The width of the rubber sealing ring 4 is 1-2 mm longer than the width of the limit groove 2, and the depth of the limit groove 2 is 7-9 mm.

[0031] In this embodiment, the width of the rubber sealing ring 4 is designed to be longer than that of the limiting groove 2, specifically, the extra length is 1-2 mm. This design enables the rubber sealing ring 4 to produce a certain amount of compressive deformation when installed in the limiting groove 2, so as to fit more closely against the side wall of the limiting groove 2, forming a better sealing effect. At the same time, the extra part can also provide a certain amount of elastic reserve to cope with possible minor deformations or vibrations. The depth of the limiting groove 2 not only ensures that the rubber sealing ring 4 has enough space for compressive deformation, but also does not cause difficult installation or affect the layout of other components due to excessive depth. The appropriate depth also helps to improve the stability of the rubber sealing ring 4 and prevent it from falling off or shifting due to external forces during operation.

[0032] In a further preferred embodiment of the present utility model, the limiting groove 2 is provided with a titanium metal surface, and the titanium metal surface is located between the two plastic protective layers 3. The rubber sealing ring 4 is in contact with the titanium metal surface and the two plastic protective layers 3.

[0033] In this embodiment, titanium metal is known for its high strength, low density, excellent corrosion resistance, and good biocompatibility. These properties make it an ideal material for many high-end application fields. In the present utility model, the introduction of the titanium metal surface aims to improve the durability and corrosion resistance of the limiting groove 2 to cope with the harsh environment that may be encountered during the production process of electrolytic copper foil. The rubber sealing ring 4 is in contact with the titanium metal surface and the two plastic protective layers 3 at the same time. This multi-level contact design not only improves the sealing effect but also ensures that the rubber sealing ring 4 can be evenly stressed when under pressure, thus extending its service life.

[0034] In summary, compared with the related art, this device can limit the rubber sealing ring 4 by setting the limiting groove 2, effectively prevent the spilled copper sulfate from corroding the cathode roller by setting the rubber sealing ring 4, and form an O-shaped structure by connecting the rubber sealing ring 4 end to end through the limiting component, while facilitating the installation and disassembly of the rubber sealing ring 4.
