Spraying device for surface treatment of electrolytic copper foil

The invention provides a spraying device for electrolytic copper foil surface treatment, which comprises a water storage tank, two spraying seats are fixedly mounted on the inner side of the water storage tank, a suction seat is fixedly mounted on one side of each of the two spraying seats, first flow guide rods are rotatably connected to the two sides of the interior of each spraying seat, and a spraying pipeline is fixedly mounted at the top of each spraying seat. The device has the beneficial effects that water for washing can be sprayed into the spraying seat through the arranged spraying pipeline, and then the first flow guide rod rotating at a high speed rotates in the spraying seat, so that the water can be sprayed into the spraying seat; the first flow guide rod can send external air into the spraying base to impact water sprayed out of the spraying pipeline, the water sprayed out of the spraying pipeline can be refined into small water mist, and therefore the water mist can be attached and sprayed to
