The invention provides a continuous aluminum foil oxidation device provided with an anode conductive device. The device comprises a working frame, a liquid storage tank and a plurality of electrolytictanks, wherein the working frame is provided with a working platform, and the working platform is provided with the plurality of electrolytic tanks; the liquid storage tank and each electrolytic tankare correspondingly filled with electrolyte with set concentration; the electrolyte in each electrolytic tank is soaked with a cathode grid plate and an anode conductive supporting post; the cathodegrid plates are uniformly distributed and fixed at the bottom of each electrolytic tank; each electrolytic tank is movably connected with an isolating cover through hydraulic telescopic rods at two ends; each anode conductive supporting post comprises an insulating hollow column and a conductive body; a lead penetrates through the insulating hollow column to be connected with the conductive body;and the conductive body is directly contacted with an aluminum foil. According to the device, a liquid level detector, a temperature detector, a PH detector and a heater are arranged in the liquid storage tank to maintain the liquid level, the temperature and the electrolyte concentration of the electrolyte in the liquid storage tank in a balanced manner, so that the electrolyte remains good stability; the anodic oxidation process of the aluminum foil is stable; and the performance of the produced oxidized aluminum foil is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum foil oxidation equipment, in particular to an aluminum foil continuous oxidation equipment with an anode conductive device. Background technique [0002] In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc., expand the scope of application, and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodic oxidation technology is currently the most widely used and most successful. of. [0003] The process of using aluminum or aluminum alloy products as anodes, placing them in an electrolyte solution for electrification, and using electrolysis to form an aluminum oxide film on the surface is called anodic oxidation treatment of aluminum and aluminum alloys. After anodic oxidation treatment, an oxide film of several microns to hundreds of microns can be formed on the surface of aluminum. Compa...

Problems solved by technology

[0005] In the prior art, when carrying out the work of batch anodic oxidation coating, it can only rely on manual experience to replenish the coating electrolyte, so that the solute concentration of the electrolyte in the electrolytic tank can be maintained at the specified working concentration

This method of artificially replenishing the electrolyte not only consumes a lot of manpower, but also cannot ensure that the liquid level, temperature and concentration of the electrolyte in the electrolytic tank meet the requirements, and it is easy to affect the coating quality due to insufficient or excessive electrolyte concentration in the electrolytic tank. ; In addition, because the electrolyte is a highly corrosive liquid and has volatile characteristics, the existing open electrolysis method is also required
