Description

Technical Field

[0001] The invention relates to the technical field of copper foil rolling, in particular to a rolling device for electrolytic copper foil. Background Art

[0002] China's new energy vehicle sales are expected to reach 11.5 million units in 2024. According to the latest report released by the Gaogong Industry Research Institute of Energy Storage (GGII), China's energy storage lithium battery shipments reached a record 116 GWh in the first half of 2024, an increase of 41% over last year, showing strong demand for green energy technology. This growth is mainly driven by the power energy storage market, indicating that annual shipments may exceed 240GWh. And most of its negative electrode current collectors are electrolytic copper foil. According to statistics from the electrolytic copper foil industry chain, it is estimated that by the end of 2024, my country's total electrolytic copper foil production capacity will reach 2.113 million tons, of which lithium battery copper foil will be 1.414 million tons and electronic circuit copper foil will be 702,000 tons. In the production process of electrolytic copper foil, the foil machine peels, leads and reels the foil between the roller systems. The non-parallel or unsupported parts between the roller systems will cause the copper foil to wrinkle and fold. This will lead to the production of invalid copper foil, which will seriously affect the production efficiency of the enterprise. It will also indirectly affect the production of downstream customers.

[0039] The use method and advantages of the present invention: When the electrolytic copper foil winding device is in operation, the working process is as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the copper foil passes through the liquid squeezing roller 207 and the conductive roller 208, passes through the oven 103 in sequence, passes through the lower fan assembly 801 and the upper fan assembly 901, and then passes through the arched flattening roller 608 and the tension roller 210. The motor 302 drives the winding roller 303 to rotate and roll the copper foil. The arched flattening roller 608 is a curved roller surface with an arc of 10 mm and is made of rubber soft material. The arched flattening roller 608 is installed between the fan of the raw foil machine and the tension roller 210, and belongs to the top foil type guide roller and the copper foil M surface The copper foil is guided through the bow-shaped flattening roller 608 and then reaches the tension roller 210. An additional bow-shaped flattening roller 608 is installed between the lower fan assembly 801 and the upper fan assembly 901 and the tension roller 210 to support and extend the edge and middle of the copper foil to prevent the copper foil from shaking after passing through the oven 103 and the fan, thereby causing the edge of the copper foil to fold and wrinkle. By rotating the adjustment knob 407, the adjustment rod 406 is driven to rotate, and the transmission plate 501 of the same group is driven by the action of the thread. The push block 505 contacts the trapezoidal block 601 through the inclined surface and pushes it to rise in the guide groove 402, so that the height of the bow-shaped flattening roller 608 changes. The height of the bow-shaped flattening roller 608 is controlled to adapt to the optimal flattening state of the copper foil. When the height of the bow-shaped flattening roller 608 is adjusted, the copper foil will be tilted. The adjusting knob 407 is rotated to drive the adjusting rod 406 to rotate, and at the same time, the first bevel gear 408 is engaged with the second bevel gear 704 to drive the transmission shaft 701 to rotate in the support block 702, and then the third bevel gear 705 is engaged with the fourth bevel gear 803 and the fifth bevel gear 903 to drive the lower fan assembly 801 and the upper fan assembly 901 to rotate in the same direction, so that when the height is adjusted, the lower fan assembly 801 and the upper fan assembly 901 follow the rotation and always remain parallel to the copper foil, thereby improving the heat dissipation efficiency.
