An apparatus for cleaning an electrode rolling roll by removing contaminants from the electrode rolling roll, the apparatus comprising: a cleaning part configured to bring the rolling roll into contact with a cleaning member to thereby clean the rolling roll; an air spray unit configured to spray air to the rolling roll; a scraper unit configured to mechanically remove cleaning liquid and foreign substances attached to the rolling roll; characterised in that the apparatus comprises a heating unit configured to dry the rolling roll by applying heat to the rolling roll and in that the scraper unit comprises: a scraping pad having a tip portion formed therein to thereby scrape off foreign materials attached to the surface of the rolling roll in contact with the surface of the rolling roll; a moving rail configured to provide a path for reciprocating the scraper unit in a front-rear direction; and a body unit having a pad holder for fixing the scraping pad and a moving member for moving the scraper unit along the moving rail at an external side, and having a motor for providing power for driving the moving member at an inside; wherein the scraper unit is configured to scrape off foreign materials while the tip portion repeatedly contacts and separates from the rolling roll at regular rolling distance intervals, as the scraper unit reciprocates on the moving rail by the moving member. a cleaning part configured to bring the rolling roll into contact with a cleaning member to thereby clean the rolling roll; an air spray unit configured to spray air to the rolling roll; a scraper unit configured to mechanically remove cleaning liquid and foreign substances attached to the rolling roll; characterised in that the apparatus comprises a heating unit configured to dry the rolling roll by applying heat to the rolling roll and in that the scraper unit comprises: a scraping pad having a tip portion formed therein to thereby scrape off foreign materials attached to the surface of the rolling roll in contact with the surface of the rolling roll; a moving rail configured to provide a path for reciprocating the scraper unit in a front-rear direction; and a body unit having a pad holder for fixing the scraping pad and a moving member for moving the scraper unit along the moving rail at an external side, and having a motor for providing power for driving the moving member at an inside; wherein the scraper unit is configured to scrape off foreign materials while the tip portion repeatedly contacts and separates from the rolling roll at regular rolling distance intervals, as the scraper unit reciprocates on the moving rail by the moving member. a scraping pad having a tip portion formed therein to thereby scrape off foreign materials attached to the surface of the rolling roll in contact with the surface of the rolling roll; a moving rail configured to provide a path for reciprocating the scraper unit in a front-rear direction; and a body unit having a pad holder for fixing the scraping pad and a moving member for moving the scraper unit along the moving rail at an external side, and having a motor for providing power for driving the moving member at an inside; wherein the scraper unit is configured to scrape off foreign materials while the tip portion repeatedly contacts and separates from the rolling roll at regular rolling distance intervals, as the scraper unit reciprocates on the moving rail by the moving member.
