The head of the metal plate strip is firstly wound on a mandrel of a coiling machine in the coiling process, the rotation of the mandrel drives a plate coil to be wound on the mandrel for one circle, and the diameter of the mandrel is reduced to a certain degree, and a cold-rolled plate coil is unloaded, so that the metal plate strip is coiled. In the process, the plate belt is pressed on the belt head from the second circle, due to the problem of plate thickness, a small amount of gaps are reserved between the second layer plate belt and the mandrel at the position of the belt head, the pressure between the inner layers is increased when the outer layer plate belt is gradually increased, and a transverse indentation, namely a belt head mark, is reserved on a plurality of layers of metal plates at the position of the belt head. In severe cases, the tape head prints can be dozens of layers with the longitudinal length of nearly one hundred meters, and the steel plates can only be used as secondary products, thereby seriously influencing the benefit of enterprises.
At present, when a metal strip is coiled, a thicker layer of rubber sleeve is sleeved on the outer layer of a mandrel of a coiling machine to buffer the pressure formed by a plate strip in the coiling process, so that scratches formed in the plate strip coiling process are reduced, the surface quality and the yield of the plate strip are improved, but the strip head print caused by the head of the plate strip cannot be eliminated; moreover, the rubber sleeve may be cut by the pressure of the tape head where it contacts the tape head. When uncoiling, a metal plate coil needs to be sleeved on a mandrel with a rubber sleeve, and the phenomenon that the head (tape head) of the inner ring of the tape coil cuts the surface of the rubber sleeve often occurs in the operation process of sleeving the metal plate coil into the rubber sleeve. After the surface of the rubber sleeve is damaged, when the sleeve expands along with the reel, stress can be generated at the damaged position, so that the whole rubber sleeve is torn and scrapped, and the service time is short.
