本发明公开了一种幅宽可控的电解铜箔生箔系统，包括有阴极辊，阴极辊安装在阴极辊滚轴上，在阴极辊上绕设有至少两条屏蔽带，屏蔽带与阴极辊为同步运转结构；屏蔽带之间留有间隔。本发明通过在阴极辊上设置具有一定间隔的屏蔽带，使屏蔽带能在阴极辊的带动运转，从而能够实现以下优点：第一，可制备不同幅宽的电解铜箔，降低了边料的报废率，提升了成品率，节约电能耗降低了生产成本；第二，铜箔幅宽可通过屏蔽带直接调节，无需停机更换阴极辊，从而实现连续运转，提高生产效率；第三，取消了O型圈密封装置，节省了因购置O型圈产生的费用；第四，由于屏蔽带与阴极辊表面紧贴，因此密封效果良好，铜箔表面不会产生铜箔铜粉及撕边缺陷。

The invention discloses an electrolytic copper foil production system with a controllable width, which includes a cathode roller, the cathode roller is installed on the cathode roller roller, and at least two shielding belts are wound on the cathode roller, the shielding belt and the cathode The rollers are of synchronous operation structure; there is a gap between the shielding belts. In the present invention, shielding tapes with a certain interval are arranged on the cathode roller, so that the shielding tape can be driven by the cathode roller, so as to achieve the following advantages. First, electrolytic copper foils of different widths can be prepared, which reduces the edge material The scrap rate improves the yield, saves electricity and energy and reduces the production cost; second, the width of the copper foil can be directly adjusted through the shielding belt, without the need to stop the replacement of the cathode roller, so as to achieve continuous operation and improve production efficiency; third, cancel The O-ring sealing device saves the cost of purchasing O-rings. Fourth, since the shielding tape is closely attached to the surface of the cathode roller, the sealing effect is good, and the copper foil surface will not produce copper foil copper powder and tear edge defects.
