PURPOSE: A tube marking device for a water-purifying line pipe is provided to form a shape of a marking line with a plurality of lines or adjust the thickness of the lines of each marking line, thereby improving the workability of a corresponding assembly process by marking properly the marking lines to various kinds of embedded components. CONSTITUTION: A tube marking device for a water-purifying line pipe includes a tube conveying device (100), a stamping device (200), a printing paper feeding device, and a withdrawing device (400). A plurality of rollers (110) of the tube conveying device is mounted to face each other. The rollers are rotated by the operation of a driving motor (120) and press the outer circumference of a tube (T) so that conveying the tube is induced by the tube conveying device. The stamping device includes a pair of jigs (220) which are heated by a heating member (210). The jigs are mounted on a pressing stand (230) to face each other and press both sides of the printing paper (B) on the outer circumference of the tube, thereby thermally printing. The printing paper supply device repeatedly and continuously supplies the printing paper mounted on a supply roll (310) to be positioned between the jigs of the stamping device and the tube by a guide roll (320). The withdrawing device includes a guide member (410) and horizontally induces the tube supplied from the tube conveying device. The tube conveying device is composed of two base rollers and two control rollers. |
