A first motor 15 is fixedly connected to the U-shaped frame 11, and a first gear 13 is fixedly connected to the drive shaft of the first motor 15. A second gear 14 is fixedly connected to the outer ring of the annular cylinder 5, and the first gear 13 and the second gear 14 are meshed together. Specifically, the first motor 15 drives the first gear 13 to rotate, and because the first gear 13 and the second gear 14 are meshed together, the second gear 14 drives the annular cylinder 5 to rotate.

[0026] Furthermore, during the painting operation, the ring cylinder 5 is adjusted to be close to one end of the bracket 1.

[0027] An air outlet pipe 7 is fixedly connected to the inner ring of the ring cylinder 5. The air outlet pipe 7 is connected to the ring cylinder 5. There are multiple air outlet pipes 7, which are evenly distributed around the inner ring of the ring cylinder 5.

[0028] When the ring cylinder 5 rotates around the rod, it drives the air outlet pipe 7 to rotate synchronously, expanding the range of air force action, avoiding the air force always acting on the same position, and improving the drying effect.

[0029] An electric heating block 6 is installed inside the annular cylinder 5. The electric heating block 6 can rapidly heat the gas passing through the annular cylinder 5, so that the ejected gas has a certain temperature.

[0030] The inclined setting of the air outlet duct 7 can also expand the range of airflow.

[0031] A ring sleeve 9 is rotatably connected to the outside of the ring cylinder 5. The ring sleeve 9 is fixedly connected to the U-shaped frame 11. A through groove 8 is provided on the outer ring of the ring cylinder 5, and the ring cylinder 5 communicates with the ring sleeve 9 through the through groove 8. A fan 10 is fixedly connected to the top of the U-shaped frame 11, and the air outlet of the fan 10 communicates with the ring sleeve 9. The through groove 8 is provided so that the ring cylinder 5 can remain in communication with the ring sleeve 9 even when rotating.

[0032] The blower 10 delivers outside air to the inside of the ring sleeve 9 and enters the inside of the ring cylinder 5 through the through groove 8. The electric heating block 6 can quickly heat the gas passing through the ring cylinder 5 and then spray it out through the air outlet pipe 7 to dry the painted rod.

[0033] By setting up structures such as ring cylinder 5, ring sleeve 9 and air outlet pipe 7, the ring cylinder 5 rotates around the rod, driving the air outlet pipe 7 to rotate synchronously, expanding the range of air force action, avoiding always acting on the same position, ensuring the uniformity of drying, and improving the drying effect.

[0034] One end of the support 1 has a sliding channel 3, inside which a slide 4 is slidably mounted. A roller 19 is located at the bottom of the slide 4. A round rod 17 is fixedly connected to the slide 4, and a lead screw 16 is rotatably connected to it.

A second motor 18 is fixedly connected to the slide 4, and the lead screw 16 is fixedly connected to the drive shaft of the second motor 18. Specifically, the second motor 18 drives the lead screw 16 to rotate, and through the mating zone of the round rod 17, drives the annular cylinder 5 surrounding the rod to move along the axial length of the rod, further ensuring uniform drying.
