The utility model has the advantages that: the device enables the edge of the strip steel to be contacted with and limited by the circular edge of the limiting disc through the rolling shaft and the limiting disc arranged on the material pressing frame, and the edge of the strip steel is tidy and beautiful when the strip steel is wound on the winding roller; under the action of the hydraulic cylinder and the wrapper arm, the edge of the strip steel is in contact with the circular edge of the limiting disc, the strip steel is prevented from falling off from the limiting disc, the limiting function is guaranteed to be effective all the time, the edge of the strip steel is guaranteed to be neat and attractive all the time when the strip steel is wound, and the steel material of the limiting disc ensures that the strip steel can be used for a long time and is not easy to damage.

When the width of the strip steel is changed, the limiting discs are adjusted left and right through the threads arranged on the rolling shaft, the distance between the two limiting discs is changed and is kept consistent with the width of the strip steel, so that the purpose of changing the width of the strip steel can be achieved, the limiting function is achieved, and the auxiliary effect of the edge tidiness of the strip steel on the rolling function of the strip steel is achieved.

In daily operation, auxiliary rolling can be completed only by starting the servo motor; when the width of the strip steel is changed, the position of the limiting disc is adjusted by only twisting the limiting disc, so that the technical difficulty is avoided, and the operation personnel can master the position easily; moreover, the device has fewer workpieces and is more convenient for later maintenance and repair.
