The thermal transfer paper is tensioned by the bottom of the tensioning rod 23 and then passes through the top of the plastic barrel.

[0040] At this time, the positioning plate 5 is pushed down by the cylinder 4. When the positioning plate 5 is descending, it can drive the support frame 7 and the internal lower pressure roller 9 to descend, so that the lower pressure roller 9 can squeeze the thermal transfer paper and the plastic barrel. When the plastic barrel rotates, it can drive the lower pressure roller 9 to rotate. The other end of the thermal transfer paper is fixed to the outside of the placement roller 28, and the interior of the placement roller 28 has a micro motor that can drive the placement roller 28 to rotate, so that the printed thermal transfer paper can be stored.
