Problems solved by technology

In the actual production process, due to the slow speed of the cathode roller during work, after the copper foil is peeled off, some cathode rollers will be exposed to the air for a long time, which is prone to oxidation and forms an oxide layer, which affects the formation of electrolytic copper foil, resulting in Product quality is unstable

Embodiment Construction

[0035] refer to Figure 1 to Figure 5As shown, a special on-line anti-oxidation device for cathode rolls of the present invention includes an isolation cover 1 that is arranged on the front side of the peeling roll along the rotation direction of the cathode roll, and several air inlet joints 2 are distributed on the upper surface of the isolation cover 1. The joint 2 is connected with an external compressed nitrogen source pipeline; a lifting and translation mechanism 3 is connected to the proximal end of the isolation cover 1 away from the peeling roller.

[0036] The upper and lower ends of the isolation cover 1 opposite to the cathode roll surface are respectively provided with adjustable isolation components 4, and the distance between the free end of the adjustable isolation component 4 and the cathode roll surface is 0.8-1.2 mm.

[0037] At the left and right ends of the isolation cover 1, there are dynamic sealing components 5 that match the end faces on both sides of ...

Abstract

The invention discloses a special online anti-oxidation device for cathode rolls; it belongs to the technical field of anti-oxidation for cathode rolls; The air inlet joint is connected to the external compressed nitrogen source pipeline; the upper and lower ends of the isolation cover and the cathode roll face are respectively provided with adjustable isolation components; The dynamic sealing assembly with matching end faces, through the cooperation of the adjustable isolation assembly and the dynamic sealing assembly, a sealed chamber with 0.8-1.2mm openings at the upper and lower ends is formed between the isolation cover and the cathode roller, and the sealed chamber is filled with nitrogen, located at The nitrogen pressure in the sealed chamber is 0.1-0.3Mpa stronger than the atmospheric pressure outside the sealed chamber; the present invention aims to provide a special online anti-oxidation device for cathode rollers with compact structure, unique sealing method and good effect; it is used for cathode rollers on foil production machines online anti-oxidation.

Description

technical field [0001] The invention relates to an online protection structure for a cathode roller, and more specifically, relates to an online anti-oxidation device dedicated to a cathode roller. Background technique [0002] Electrolytic copper foil is an important material for the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. In the rapid development of today's electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication. Since 2002, the production value of printed circuit boards in my country has entered the third place in the world, and as the substrate material of PCBs, copper clad laminates have also become the third largest producer in the world. As a result, my country's electrolytic copper foil industry has developed by leaps and bounds in recent years. [0003] The foil machine is the key equipment for preparin...
