Description
Technical Field
The invention relates to the technical field of production of formed aluminum foils, in particular to a fishtail roller.
Background
The formed foil is a product formed by expanding the surface area of a special high-purity aluminum foil after electrochemical or chemical corrosion and forming a layer of oxide film (aluminum oxide) on the surface through electrochemical forming. The aluminum foil is divided according to voltage, and the formed aluminum foil is generally divided into four types, namely extremely low voltage, medium and high voltage; the thickness is divided into 50-125 μm; a distinction is made by the use, including positive and negative foils, and conductive foils.
In actual production, when electrochemical corrosion is carried out on high-purity aluminum foil, the high-purity aluminum foil is conveyed into a corresponding electrolytic cell by using a transmission structure consisting of a roller set, and the process requires that the rollers have good guidance performance and corrosion resistance. And current running roller is mostly the cylinder that the surface covering has the guide way that is on a parallel with the axis, and this kind of running roller very easily makes foil both sides edge fold appear when the guide foil, and operating personnel can only open a book the tension through appropriate increase and adjust at present, nevertheless opens a book the tension and lead to the fact disconnected paper tinsel easily after increaseing, and then weakens the bending characteristic of product, and causes finished product coiled material's void ratio to improve easily, reduces finished product quality.
