Rewinding shaft for electrolytic copper foil production and using method thereof

Abstract

The invention discloses a rewinding shaft for electrolytic copper foil production and a using method thereof and belongs to the technical field of copper foil processing. The technical key points are that: the rewinding shaft comprises a rolling wheel, wherein a rubber layer is covered on the outer surface of the rolling wheel. The using method comprises the following steps of: (1) starting a cathode roller and adjusting rotating speed of the cathode roller to be between 1.5 and 2.5 m / min; (2) wetting the surface, opposite to the rewinding shaft, of the opening of the copper foil with water; (3) adhering the wetted opening of the copper foil to the surface of the rubber layer on the rewinding shaft; (4) starting the rewinding shaft and controlling the range of the rotating tensile force of the rewinding shaft to be between 200 and 300 N; and (5) dragging and rotating the copper foil on the rewinding shaft for 2 to 5 loops, fastening the copper foil on the rewinding shaft, and adjusting the rotating speed of the cathode roller to be in the range according to the gram weight and thickness of the copper foil required to be produced. The rewinding shaft for the electrolytic copper foil production solves the problem of reel bottom imprint during the production of ultrathin copper foil, increases qualification rate of the products and reduces production cost, and is applied to electrolytic copper foil production.

Description

Technical field [0001] The invention relates to a winding shaft, and more specifically, to a winding shaft for electrolytic copper foil production; the invention also relates to a method of using the winding shaft. Background technique [0002] The production of electrolytic copper foil is the continuous production of barrel plating. The winding shaft is used for synchronous winding. When winding, the steel winding shaft is used for winding. When the winding shaft draws the copper foil, double-sided adhesive is often used to bond the roller and the copper foil. Start the rotation of the cathode roller and the winding shaft, and ensure a certain tension to achieve continuous barrel plating production. When winding, double-sided adhesive bonding and traction will cause obvious horizontal prints on the bottom of the copper foil roll. When producing ultra-thin copper foil, the bottom prints of the roll are more obvious. Usually, 8μm copper foil will disappear after 50-80 meters. Bri...

When rolling up, double-sided adhesive tape is used to bond and draw, resulting in obvious horizontal imprints on the bottom of the copper foil roll. When producing ultra-thin copper foil, the imprints on the bottom of the roll are more obvious. Usually, the 8μm copper foil takes 50-80 meters to disappear. Bring unnecessary waste to production
