The invention discloses a rotational reflector device used on an
inflatable shaft of a
coating machine. The rotational reflector device comprises the
inflatable shaft and a rotating sleeve. The rotating shaft is rotationally arranged on the
inflatable shaft. At least one set of reflectors are arranged on the rotating sleeve. A rotating positioning device is further arranged between the rotating sleeve and the inflatable shaft. According to the rotational reflector device, by means of the structural innovation, the previous working flow of carrying out deflating again, rotating the inflatable shaft and carrying out inflating again for fixing is transformed into the operation of rotating the reflectors which are low in
mass and small in size, the procedure of deflating and inflating is not needed any more, and thus the labor intensity of production workers is relieved; and the new mechanism is convenient and fast to adjust and low in labor intensity, the previous cumbersome operation process is simplified, the production efficiency is greatly improved, and the development requirement of modern machines is better met through the user-friendly operation concept.
