Description

Technical Field

[0001] The invention relates to the technical field of rubber-coated rollers, and in particular to a lightweight and high-strength rubber-coated roller and its application. Background Art

[0002] Electrolytic copper foil is formed by the copper ions in the electrolyte deposited on the smooth rotating titanium plate circular cathode roller. At present, the domestic production of electrolytic copper foil mainly adopts roller cathode (cathode roller) and insoluble anode (anode plate) to continuously produce electrolytic copper foil. There are many types and quantities of rubber-coated rollers in the electrolytic copper foil production equipment. There are more than a dozen rubber-coated rollers on the raw foil machine and hundreds of rubber-coated rollers on the surface treatment machine. Their precision directly affects the quality of electrolytic copper foil. At present, the rubber-coated rollers are generally metal cylinders. Due to the large specific gravity of metal, the weight of the rubber rollers is generally between 50-200 kilograms, which makes it difficult to control the static and dynamic balance of the rollers. In particular, many rubber-coated rollers are unpowered rollers, which rely on 4.5 micron copper foil to pull it to rotate. If the weight of the rubber-coated roller is large and the balance is biased, the pulling resistance will increase, resulting in damage to the copper foil surface when the copper foil pulls the roller to rotate.
