Roll changing production line for rolling mill

The utility model provides a roll changing production line for a rolling mill. The roll changing production line comprises a cold rolling mill and a roll changing machine, the roller changing machine comprises a linear module, a mechanical arm structure and a moving structure. The mechanical arm structure is used for clamping a roller of the cold rolling mill; the mechanical arm structure is arranged at the moving end of the linear module. The linear module is used for driving the mechanical arm structure to move in the length direction of the linear module. The linear module is matched with the mechanical arm structure to be used for pulling out a roller of the cold rolling mill. A body of the linear module is arranged on the moving structure, and the moving structure is used for driving the linear module to move. The utility model solves the problems that the roller of the traditional cold rolling equipment is easy to damage and the efficiency of a manual dismounting method is low, and has the advantages of
