Description

Technical Field

[0001] The present invention relates to the technical field of vacuum coating equipment, and more specifically, to a tunnel-type continuous winding vacuum coating production device for stainless steel decorative coils. Background Art

[0002] Vacuum coating is to deposit various metal and non-metal films on the surface of plastic parts by distillation or sputtering under vacuum conditions. This method can obtain a very thin surface coating, which has the outstanding advantages of fast speed and good adhesion. The metal used in the operation is used as a functional coating for high-end products, such as an internal shielding layer. Stainless steel decorative rolls mainly use vacuum ion plating, also known as vacuum coating. Vacuum electroplating is now a more popular method, and the products produced have a strong metallic feel and high brightness. Compared with other coating methods, it has lower costs and less pollution to the environment, and is now widely used in various industries.

[0003] In the prior art, coil plating usually adopts a single chamber or multiple chambers. When coating in a single chamber or multiple chambers, carbon brushes are used for conduction, and there are no corrective measures for steel strips. This will bring many production problems. First, when coating in a single chamber or multiple chambers, the steel strip is bent too much, causing a certain irreversible deformation of the steel strip, resulting in different stresses between the substrate and the film layer, affecting the adhesion of the film layer, causing film falling off, especially for thick plates. It is only suitable for thin plate coating; second, carbon brushes are used for conduction. Due to the friction of the carbon brushes, the carbon brushes are worn, forming carbon powder to pollute the vacuum chamber, and there is a phenomenon of electric sparks when there is poor contact, resulting in unstable bias voltage, affecting the quality of coating, especially in coil plating, when the coating time is long, the reliability of using carbon brushes for conduction cannot be ignored. The strip steel for coil plating is generally longer, and without corrective measures for steel strips, it may not work due to the deviation of the strip steel. Summary of the invention
