The invention discloses a slitting device for an electrolytic
copper foil. The slitting device for the electrolytic
copper foil comprises a
machine shell with openings in the two ends, sealing guide rollers fixedly installed at the two ends of the openings of the
machine shell, a dust collecting base fixedly installed in the
machine shell, a
cutting carrier roller arranged above the dust collecting base and rotationally connected with the machine shell, a
cutting tool arranged above the
cutting carrier roller and slidably connected with the machine shell, and a first dust removing roller and asecond dust removing roller arranged on one side of the dust collecting base, wherein the first dust removing roller and the second dust removing roller are rotationally installed on the machine shell, and the first dust removing roller is arranged above the second dust removing roller. In the whole working process of the slitting device, on one hand,
copper powder attached to the surface of thecopper foil can be reduced, the attached copper
powder is mainly concentrated on the two
cut side edges, then the attached copper
powder is swept and transferred, the quality of the produced
copper foil is guaranteed, the collected copper powder can be transferred in time, and it is guaranteed that after long-time sweeping work is carried out, a good sweeping effect can still be kept.
