The inventor finds that the contact surface between the conventional film separating cutter 810 and the hub protection film 300 is too large, and in the scheme, the hub protection film 300 is abraded in the rotating process. In the above embodiment, when the first motor 240 drives the first film scraping portion 200 to rotate and the second motor 250 drives the second film scraping portion 210 to rotate, the two portions roll on the hub film and generate a pressing motion for gradually pressing the hub film.
