Novel continuous electroplating cathode roller

The utility model discloses a novel continuous electroplating cathode roller which comprises supporting frames and a cathode roller body, the cathode roller body is arranged between the supporting frames, the top of each supporting frame is connected with an installation mechanism, and the top of each supporting frame is connected with a polishing mechanism. A nut rotates and can conduct threaded sliding with a first threaded rod, when the nut slides to the bottom of a second connecting block in a threaded mode, the second connecting block can be extruded and fixed, so that a second mounting base is fixed, the cathode roller can be fixed after the second mounting base is fixed, and when a polishing roller slides to make contact with the cathode roller, the polishing roller is fixed; the second motor can be started, the second motor can drive the grinding roller to rotate when working, the grinding roller rotates to grind the surface of the cathode roller, and at the moment, the machine can be started to drive
