[0025] In this embodiment, the dust blowing horizontal plate 2 , the connecting side plate 21 , the dust blowing mesh port 23 , the small fan 3 and the transparent air guide plate 4 constitute the dust blowing structure of the short-wave infrared heating tube 1 .

[0026] As a preferred embodiment, the dust blowing structure of the short-wave infrared heating tube 1 effectively prevents impurities such as printed fibers or dust from adhering to the short-wave infrared heating tube 1, thereby ensuring the cleanliness of the tube surface of the short-wave infrared heating tube 1, facilitating the infrared radiation of the short-wave infrared heating tube 1 to fully irradiate and dry the ink on the surface of the printed material, thereby improving the drying effect of the short-wave infrared heating tube.
