Roller frame

The utility model relates to the technical field of cold rolling, in particular to a roller frame. The roller frame comprises two oppositely-arranged mounting mechanisms, each mounting mechanism comprises a support and a supporting unit used for supporting a roller head, the two corresponding supporting units on the two mounting mechanisms are used for supporting the roller heads at the two ends of a roller respectively, and each supporting unit comprises two rolling wheels rotationally arranged on the supports. The roller head can be placed between the two rolling assemblies, the rolling wheels are provided with protruding parts extending out of the top of the support, and the roller head can be supported between the protruding parts of the two rolling wheels in a rolling mode. Therefore, when the roller is subjected to surface inspection, the roller can be driven to rotate by rolling the roller, so that 360-degree dead-angle-free surface quality inspection can be performed on the roller, the occurrence of r
