Abstract

The invention discloses a continuous vacuum coating sealing lock for a metal strip. The continuous vacuum coating sealing lock comprises an upper sealing cover, a lower sealing cover and sealing rollers, wherein the upper sealing cover and the lower sealing cover are detachable, the sealing rollers are arranged between the upper sealing cover and the lower sealing cover, and shaft shells adapted to the sealing roller are arranged on the upper sealing cover and the lower sealing cover respectively; a shaft shell flexible layer is arranged on the inner surface of each shaft shell; the sealing rollers comprise a plurality of upper sealing rollers and a plurality of lower sealing rollers, the upper sealing rollers and the lower sealing rollers are arranged in a staggered mode, sealing roller flexible layers are arranged on the upper sealing rollers and the lower sealing rollers respectively, and the surfaces of the sealing roller flexible layers of the upper sealing rollers make contact with the surfaces of the sealing roller flexible layers of the lower sealing rollers respectively; a sub-chamber is formed among every three adjacent sealing rollers; each sub-chamber is connected with a vacuum pump; and the metal strip passes through the space between the upper sealing rollers and the lower sealing rollers. For the continuous vacuum coating sealing lock for the metal strip of the invention, an inlet cavity is divided into a plurality of sub-chambers, and the shaft shell form, the shaft shell flexible layers and the sealing roller flexible layers are adopted for sealing, so that the vacuumizing efficiency is greatly improved.

Description

Technical field [0001] The present invention relates to the field of vacuum plating, in particular, a continuous vacuum coating sealing lock for a metal strip, which is mainly used as a metal strip on a vacuum substrate for continuously operated metal strip surface vacuum plating. / Or exit. Background technique [0002] Metal strip usually increases its corrosion resistance in the surface plating resistance to prolong the useful life; the material of the metal strip and the different plating materials selected differently, such as plating materials It is zinc, zinc-aluminum-magnesium, aluminum-silicon, etc., plating techniques can be made of hot plating, plating, and vacuum plating. For soft steel, there is a problem that the electroplating process is difficult to produce, energy consumption and export of wastewater during electroplating process; the speed of the hot plating process is difficult to improve and contain B steel-resistant plating; for ordinary high-strength steel (...
