Cooling, pulling and straightening device for continuous solidification and production of wide-thin copper plate belt and copper alloy plate belt

The utility model relates to a cooling, pulling and straightening device for continuous solidification and production of a wide-thin copper plate belt and a copper alloy plate belt. The device comprises a cooling liquid tank body, the inlet end and the outlet end of the cooling liquid tank body are respectively provided with a group of pulling and straightening rollers, each group of pulling and straightening rollers consists of two pairs of roller drums leaning against each other, the cooling liquid tank body is internally provided with a positioning roller, and a servo motor is connected with the pulling and straightening rollers through speed reducers and conveying belts. The cooling, pulling and straightening are integrated, so that the space is saved and the operation is simple; in addition, the upper surface and the lower surface of a metal plate can be immersed into cooling liquid at the same time, thereby solving the problem of non-uniform cooling strength of the upper surface and the lower surface of
