The abnormal appearance of the electrode is too thick, which will cause damage to the roller surface and affect the product quality. If a CCD camera is installed separately, due to the fast running speed of the roller press (80m / min) and the short distance from unwinding to the main roller, the abnormal electrode cannot be avoided from entering the main roller due to insufficient distance from equipment identification to stopping operation. Therefore, it is very necessary to provide a main roller appearance protection device of a roller press with a reasonable structure, a detection device for defect detection, an additional cache device, avoiding the inability to stop in time, saving time and low cost.
