Description

Technical Field

[0001] This utility model belongs to the field of cathode roller technology, and more specifically, it relates to a highly conductive cathode roller for producing copper foil. Background Technology

[0002] The cathode roller is a core piece of equipment in the electrolytic production of copper foil, and the quality of the titanium cylinder of the cathode roller directly affects the quality of the copper foil. As the conductor of the negative electrode in the copper foil production equipment, the shape and size of the cathode roller directly determine whether the current distribution on the roller surface is uniform, while the size and uniformity of the titanium cylinder grains directly affect the fineness of the copper foil crystallization. Chinese Patent No. CN221663043U discloses a high-conductivity cathode roller for copper foil production, comprising a cathode roller core and a titanium cylinder. The cathode roller core is located at the central axis of the titanium cylinder, and titanium side plates are fixedly installed inside both ends of the titanium cylinder. A heat dissipation ceramic is provided at both ends of the titanium cylinder, and the heat dissipation ceramic is fixedly installed on the side wall of the titanium side plate. This invention transfers heat to the cavity interior when the cathode roller rotates. Air passes through the arc-shaped heat dissipation groove, cooling the heat dissipation ceramic and its interior, thereby controlling the temperature of the cathode roller during operation, extending its service life, and preventing damage to the roller surface due to excessive temperature.

[0003] Based on the above, the inventors have discovered the following problems: The cathode roller in the above patent can effectively cool down the cathode roller by using heat dissipation ceramic, thereby improving the service life of the cathode roller. However, the heat dissipation ceramic is relatively fragile and may be damaged during use. After damage, the heat dissipation ceramic needs to be replaced in time. Since the heat dissipation ceramic is designed with concentric circles, the cathode roller in the above patent needs to be removed from the foil making machine when replacing the heat dissipation ceramic, which is quite troublesome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a highly conductive cathode roller for the production of copper foil, in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a highly conductive cathode roller for producing copper foil, thereby solving the problem of the cumbersome process of replacing the heat dissipation ceramic in current cathode rollers.

[0006] The purpose and effect of this utility model, a high conductivity cathode roller for producing copper foil, are achieved by the following specific technical means:

[0007] A high-conductivity cathode roller for producing copper foil includes a roller body with side plates mounted on both sides of the roller body. A shaft is mounted at the center of the surface of the side plates. Multiple heat dissipation copper tubes are mounted inside the roller body, with both ends of the heat dissipation copper tubes extending to the surface of the side plates. Multiple heat dissipation ceramics are mounted on the surface of the side plates. The number of heat dissipation ceramics is the same as the number of heat dissipation copper tubes. The multiple heat dissipation ceramics are combined into a concentric circle, and the individual heat dissipation ceramics can be replaced separately.

[0008] Furthermore, a connecting block is installed on the surface of the heat dissipation ceramic, and a threaded hole is opened on the surface of the side plate. The plate also includes a bolt, which passes through the connecting block and rotates into the threaded hole.

[0009] Furthermore, two connecting blocks are installed on the outer diameter surface of the heat dissipation ceramic, and one connecting block is installed on the inner diameter surface of the heat dissipation ceramic. The connecting block of the inner diameter is located in the middle of the two connecting blocks of the outer diameter.

[0010] Furthermore, the heat dissipation ceramic is provided with a cavity, and the surface of the heat dissipation ceramic that contacts the side plate is provided with a groove. The groove is the same size and shape as the heat dissipation copper pipe. When the heat dissipation ceramic is installed, the groove is aligned with the part of the heat dissipation copper pipe that extends to the surface of the side plate.

[0011] Furthermore, the surface of the heat-dissipating ceramic is provided with arc-shaped heat dissipation grooves.

[0012] Furthermore, the surface of the roller is coated with a conductive coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] If a damaged heat dissipation ceramic is found, the present invention can be used to quickly replace a single damaged heat dissipation ceramic by loosening its connecting bolts, removing the damaged heat dissipation ceramic separately, replacing it with a new heat dissipation ceramic, reinstalling and tightening the bolts.
