This utility model relates to the technical field of railway
casting information marking spraying device, specifically a railway
casting information marking spraying device, including two side plates, with two take-up rollers rotatably installed between the two side plates. The end of the
transmission belt is wound around the lower part of two support shafts and connected to another take-up roller. The working end of the
nozzle plate faces the
transmission belt. In this utility model, under the support of the two support shafts, the lower transmission surface of the
transmission belt will adhere to the surface of the
casting, and then the pushing device will move on the surface of the casting. When the two drive rollers roll, they will drive the two take-up rollers to rotate, thereby gradually winding the transmission belt wound on one take-up roller onto the other take-up roller. At this time, the
pigment sprayed by the
nozzle plate can penetrate the hollowed-out
lettering of the marking and coat the surface of the casting, effectively avoiding problems such as skewed
lettering, missed spraying, and uneven ink, and improving spraying efficiency.
