[0002] Paper ring deburring machine is used in large transformers (electric power, electric furnace) to automatically remove paper ring sharp corners and burrs. To avoid the occurrence of internal discharge or breakdown accidents in high electric field and high magnetic field during transformer operation, the original transformer paper ring processing is completed by shearing by a shearing machine. After the shearing process, the shearing band and tearing band are inevitably formed with sharp corners and burrs. Usually, the operator uses a file or sandpaper to perform simple deburring work. Due to manual operation, the consistency is poor, the efficiency is low, and the quality cannot be guaranteed. And there is a blank in the market for circle deburring equipment.
