Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil unwinding equipment, and particularly relates to a holding mechanism for stainless steel coil unwinding. Background Art

[0002] A steel coil unwinder is mainly used to smoothly and continuously unwind or wind the steel coil material wound into a cylindrical shape. It is widely used in industries such as iron and steel, non-ferrous metal smelting, and machinery manufacturing, and is one of the key equipment on the production line. At present, most of the existing steel coil unwinders use a large-stroke cylinder alone to push the pressure roller to press on the winding shaft. However, the pressing force of the large-stroke cylinder changes greatly, which is likely to cause problems such as wrinkling and deviation of the material during unwinding, resulting in low unwinding efficiency, and may also cause problems such as scratching, unwinding, and deformation of the steel coil during unwinding, affecting the quality of the steel coil and increasing the processing cost. Summary of the Invention
