Strip Uncoiler machine
Overview of Strip Uncoiler machine:
1.Insert the steel roll into the uncoiler mandrel, and meanwhile, expand the mandrel to tension and fix the steel roll. The uncoiler mandrel is driven to rotate by variable-frequency AC motor, so as to make the steel plate to maintain the required certain back tension.
2.The uncoil mandrel is cantilever type and is driven by chains or standard reducer.
3.The gearbox base is made up by heavy steel plate.
4.In the mandrel, there are four expandable valves, and the expanding and retracting of the valves are controlled by the revolving hydraulic cylinder at the mandrel tail.
5.There are four main sliding blocks made of bronze.
6.The maximum diameter of the expanded mandrel with rubber sleeve is 508mm or 610mm.
