The application discloses a tissue box writing instrument, which comprises a blanking assembly, a belt conveying assembly, a transverse feeding assembly and a laser marking assembly. The blanking assembly comprises a plurality of vertically arranged blanking frames, each of which is internally provided with a plurality of tissue boxes. The blanking frames are sequentially arranged and installed on the top of the belt conveying assembly. The transverse feeding assembly is arranged at one end of the belt conveying assembly. During operation, a plurality of tissue boxes are installed in the blanking assembly. The blanking assembly conveys a single tissue box to the conveying belt of the belt conveying assembly. The conveying belt conveys the tissue box to the transverse feeding assembly. When the tissue box is separated from the conveying belt, it will automatically slide onto the inclined sliding table of the transverse feeding assembly. Then, the inclined sliding table conveys the tissue box to the laser marking assembly. When the tissue box reaches the lower part of the laser marking assembly, the conveying is paused. The laser marking assembly writes characters or graphics on the tissue box. After the writing is completed, the inclined sliding table sends out the tissue box.
