Description

Expansion protection board

This creation relates to a protective plate, in particular to an expansion protection plate for protecting a metal sheet from being retracted by the influence of an air-up axis.

According to the generally manufactured metal sheet, one end of the metal sheet is first mounted on the rotating shaft of the coiler, and a metal coil (for example, a steel coil) is formed by winding, and then unwound and processed by slitting and cutting. Provide strip metal sheets for different industries.

Wherein, in order to make the metal coil sleeved on the rotating shaft of the coiler co-rotate with the rotating shaft, the general rotating shaft is a gas rising shaft, and the gas rising shaft has a plurality of expanding members, and when the metal sheet is not installed, the expanding member is inwardly contracted. When the metal sheet is installed on the rotating shaft of the coiler, the expansion member is outwardly expanded to press the inner ring of the metal coil to fix.
