Description

[0001] The utility model relates to the technical field of conductive rollers, and particularly relates to an anti-oxidation conductive roller for lithium battery copper foil raw foil production. Background Art

[0002] At present, in the electrolytic copper foil industry, the surface of the copper foil needs to be treated to meet the requirements of different customers; the surface treatment of the copper foil mainly uses a metal conductive roller connected to the negative electrode of the power supply to make the copper foil negatively charged, and the copper foil is plated with metals such as Cr, Ni, Zn, etc. in the plating solution tank; this electroplating process requires long-term power-on. On the one hand, since the resistance of the conductive roller is relatively large compared to that of the copper wire, the conductive roller will heat up during long-term production; on the other hand, the position of the conductive roller is close to the hot air box, and the heat radiation causes the surface temperature of the conductive roller to be abnormal. To solve the copper foil quality problems caused by such defects, ensure that the surface temperature of the electro-roller is appropriate, and the temperature of the entire roller surface is uniform, an anti-oxidation conductive roller for lithium battery copper foil raw foil production is invented. Therefore, an anti-oxidation conductive roller for lithium battery copper foil raw foil production is proposed to solve the above problems. Summary of the Utility Model

A first bearing 4 is installed inside the support sleeve 2, and a second bearing 5 is installed inside the right ring plate 3. The water spraying pipe 1 sequentially passes through the first bearing 4 and the second bearing 5 and is placed inside them. The outside of the support sleeve 2 is fixedly installed with a left ring plate 6 through bolts. The same roller 7 is fixedly connected to the outside of the left ring plate 6 and the right ring plate 3. The left end of the roller 7 is connected to a left shaft assembly 8, and the right end of the roller 7 is connected to a right shaft assembly 9. The left end of the left shaft assembly 8 is communicated with a water inlet joint 10, and the right end of the right shaft assembly 9 is communicated with a water outlet joint 11. Ten spiral grooves are arranged on the inner side of one end of the roller 7 close to the right shaft assembly 9, and the effective length is 300 mm. The purpose is to let water flow out of the roller 7 quickly along the spiral grooves. The material of the roller 7 is 316L. After the spiral grooves are processed, a 2-mm-thick copper coating is plated on the inner surface of the roller 7. The characteristics of copper with fast heat absorption and heat dissipation are used to quickly take away the surface temperature of the roller 7.

[0022] Further, the left shaft assembly 8 comprises a left shaft 801, a tight sealing sleeve 802 and a spring 803. The left shaft 801 is fixedly connected inside the roller 7. The right end of the left shaft 801 is sleeved with a tight sealing sleeve 802, and the outside of the tight sealing sleeve 802 is sleeved with a spring 803. Ceramic rings 804 are arranged on the right side of the tight sealing sleeve 802 and the left side of the water spraying pipe 1. The ceramic ring 804 on the tight sealing sleeve 802 is in close contact with the ceramic ring 804 on the left side of the water spraying pipe 1 by the elastic force of the spring 803, playing a role of rotary sealing.

[0023] The right shaft assembly 9 comprises a right shaft 901, a drainage ring 902, a second sealing ring 903, a fourth bearing 904 and a skeleton seal 905. The right shaft 901 is fixedly installed at one end of the right ring plate 3. A drainage ring 902 is installed at the right end of the roller 7. A second sealing ring 903 is arranged between the drainage ring 902 and the roller 7. Water quickly flows into the drainage ring 902 through the spiral grooves of the roller 7. A skeleton seal 905 and a fourth bearing 904 are sequentially arranged inside the drainage ring 902 from left to right. One end of the right shaft 901 sequentially passes through the skeleton seal 905 and the fourth bearing 904. The right shaft 901 is communicated with the water outlet joint 11. Five equidistant drainage ports 16 are arranged inside the right shaft 901. The drainage ports 16 are inclined at 45 degrees. The water in the drainage ring 902 flows into the inside of the right shaft 901 through the five drainage ports 16 and finally flows out through the water outlet joint 11.

[0024] One end of the water inlet joint 10 is provided with a third bearing 12 and a first sealing ring 13. The first sealing ring 13 is placed on one side of the third bearing 12. One end of the left shaft 801 passes through the third bearing 12 and is placed inside it. One end of the water outlet joint 11 is provided with a fifth bearing 14 and a third sealing ring 15. The third sealing ring 15 is placed on one side of the fifth bearing 14. One end of the right shaft 901 passes through the fifth bearing 14 and is placed inside it. When the roller 7 rotates normally, both the water inlet joint 10 and the water outlet joint 11 remain relatively stationary.

[0025] The working principle of the present utility model:

[0026] Cooling water enters the left shaft 801 through the water inlet joint 10, and then flows into the spray pipe 1 through the left shaft 801. The cooling water in the spray pipe 1 is sprayed vertically and evenly inside the roller 7 through the through holes. The cooling water flows down along the inner wall of the roller 7 under the action of gravity. At the same time, the copper foil drives the roller 7 to rotate. During the rotation of the copper foil 7, the cooling water quickly flows into the drainage ring 902 along the spiral grooves of the roller 7. The water in the drainage ring 902 flows into the interior of the right shaft 901 through the drainage port 16, and finally flows out through the water outlet joint 11. During the rotation of the conductive roller, under the action of gravity, the spray pipe 1 and the counterweight plate 101 are kept in position through the cooperation of the first bearing 4 and the second bearing 5. The sealing effect is better through the tight sealing sleeve 802 and the spring 803. When the roller 7 rotates, the water can flow and flow out quickly to achieve circulation, ensuring that the temperature of the roller surface is uniform during the copper foil electroplating process, and avoiding quality or appearance problems caused by uneven contact roller surface temperature on the entire foil surface. By adjusting the flow rate of the cooling water entering the conductive roller, the temperature of the roller surface can be adjusted to meet the requirements of the foil surface.
