Abstract

The invention discloses a sealing device for electrolytic copper foil and relates to the field of electrolytic copper foil production. The sealing device comprises a cathode roller and sealing rings.The circumferential faces of the two ends of the cathode roller are each provided with an annular sealing groove. The sealing rings are mounted in the sealing grooves. The sealing device further comprises two sealing device bodies, wherein the sealing device bodies are symmetrically arranged at the two sides of the cathode roller. Each sealing device body comprises one or more guiding wheels and atensioning mechanism. Each tensioning mechanism comprises a support, a locking block, a support seat, an adjustment bolt and an adjustment bracket. By means of the sealing device, before the copper foil is peeled, the sealing rubber rings are separated from the copper foil, and the edge of the copper foil cannot be torn off; and the tension, inside the sealing grooves, of the sealing rubber ringsis adjusted through the tensioning mechanisms, and furthermore, the existing problems that in the electrolytic copper foil industry, when copper foil is peeled, the copper foil is torn off due to thefact that the copper foil is in contact with rubber sealing rings, the sealing effect is not good due to dimensional deviation of the sealing rings in the using process, the sealing rubber rings arereplaced frequently, and production halt and the high rejection rate are caused due to frequent replacement of the rubber rings can be effectively solved.

Description

technical field [0001] The invention relates to the field of electrolytic copper foil manufacturing, in particular to a sealing device for electrolytic copper foil. Background technique [0002] The production process of electrolytic copper foil requires that the cathode roll should be half-intruded into the electrolytic cell (the bottom is the anode plate), and only part of the surface of the cathode roll is in contact with the electrolyte. Electrochemical reaction occurs continuously to form copper foil, and the cathode roll continuously rotates to continuously peel off the copper foil and wind it up at the tail of the machine, so as to achieve the purpose of continuous production of copper foil (such as figure 1 ). In the production of electrolytic copper foil, it is required that the longitudinal edges on both sides of the cathode roller should not be in contact with the electrolyte, otherwise the copper foil (also known as copper roots) will grow on the longitudinal ed...
