Description

Uncoiler capable of uncoiling continuously and keeping stability

Technical Field

The utility model relates to a technical field that metal wire, strap or other flexible metal material's book is tight, is convoluteed or is opened a book especially relates to incessant decoiler of opening a book and remain stable.

Background

The uncoiler is special equipment for leveling metal plates, is used for leveling steel plates on a line, can form an uncoiling, leveling and shearing production line and other plate product production lines according to relevant configuration when the steel plates are not flat, and is suitable for industries such as machinery, vehicles, metal product household appliances, steel structures and decoration. The existing uncoiler can uncoil a steel strip of a coil at any time or continuously uncoil the steel strip after pausing, but after a steel strip is completely conveyed, the uncoiler still needs to be stopped to feed the next steel strip, so that the steel strip can be continuously conveyed for subsequent processes, meanwhile, the coil head of the uncoiled steel strip is easy to generate the condition of arc bending of the transitional strip head, hidden danger is left for the subsequent processes, the condition that the steel strip is clamped in the midway of the subsequent processes is easily caused, and the working efficiency is reduced. Therefore, for the uncoiler which uncoils continuously and keeps stable, when steel strips are fed, the uncoiler stops and the coiling head causes the phenomenon that the work efficiency is reduced due to the clamping of the strips.
