[0002] Existing polishing machines for cold-rolled rollers usually consist of structures such as a fixing device, a driving device and a polishing device. When in use, the cold-rolled roller is placed between the fixing devices with the help of a hanger, and then the position of the hanger is slowly adjusted so that the fixing device can fix the cold-rolled roller. After the fixation is completed, the driving device is started to drive the cold-rolled roller to rotate at high speed, and then the grinding device is started to polish the surface of the cold-rolled roller. Although this type of device can complete the polishing of the cold-rolled roller, the installation process of the cold-rolled roller using the hanger is relatively complicated, which greatly increases the installation time, reduces the polishing efficiency, and increases the risk of safety accidents to a certain extent.
