The external fixed sleeve of the second rotating rod 710 is provided with a first gear 714, and the external fixed sleeve of the heating tube 707 is provided with a second gear 715. By setting the pre-drying mechanism 7, when the nozzle 6 sprays paint to draw lines, the blowing position of the blowing nozzle 709 can be adjusted according to the width of the spraying, so that the hot air can be blown on the paint more accurately to dry the paint, and by controlling the motor 704, the motor 704 drives the first rotating rod 705 to rotate, thereby driving the two second rotating rods 710 and the first gear 714 to rotate, thereby driving the second gear and the air outlet pipe 708 to rotate, thereby realizing the adjustment of the blowing angle of the blowing nozzle 709.
