The present invention relates to a tape roll cutting machine which cuts a tape roll in a fixed width, and more specifically, to a tape roll cutting machine having an automatic blade polishing means which polishes a blade cutting a tape roll frequently as needed to maintain high cutting quality of the tape roll, has a blade polishing means to extend a period during which a professional polishing company is asked to polish the blade to reduce an economic burden, reduces a burden for securing an installation space since a volume of the blade polishing means is small and a moving range for stopping polishing is small, and has excellent blade polishing quality since a polishing stone is prevented from being pushed by the blade or being pushed against the blade too strongly or too weakly. The tape roll cutting machine having an automatic blade polishing means according to the present invention comprises: a roll shaft on which a tape roll is inserted to be fixed; a drive means to rotate the roll shaft; a blade to cut the tape roll; a moving means to move the blade along the roll shaft, and move the blade forward and backward towards the roll shaft; a controller to control the drive means and the moving means; and a blade polishing means to polish the blade. The blade polishing means comprises: a fixing plate; a forward and backward movement plate disposed on a front of the fixing plate; a forward and backward movement member which is mounted on the fixing plate and moves the forward and backward movement plate forward and backward; and a polishing stone which is rotatably mounted on a front of the forward and backward movement plate and whose inner surface is formed in a ″V″ shape to selectively polish one surface of the blade. |
