Abstract

PURPOSE:To prevent the deflection of a spray injecting direction due to adhesion of a coating liquid and the clogging of a spray orifice, by providing a means for heating at least the spray orifice part of a nozzle head to the m.p. or more of a molten substance. CONSTITUTION:In a nozzle 6 for spraying a molten substance, a heat generator 28 heating at least the air passage 24 of a nozzle head to the m.p. of the molten substance is provided. This heat generator 28 prevents such a phenomenon that a coating liquid injected from the liquid injecting orifice 23 of the nozzle head 22 and atomized by atomizing air from the air passage 24 is turned around or rebounced to the liquid injecting orifice 23 and the air passage 24 and the adhered one is solidified by cooling and, therefore, by heating the adhered substance of the coating liquid to the m.p. or more thereof to hold the same under a molten state, the clogging of the air passage 24 due to the ahdered substance or the deflection of a spray direction is eliminated.

This heating element head is configured so that the coating liquid is injected from the liquid jet port 23 of the nozzle head n and atomized by the atomizing air from the air passage. In order to prevent the coating liquid from getting into the surrounding area, splashing and adhering to it, and causing it to cool and solidify, the coating liquid is heated above its melting point and maintained in the fj@ state. This eliminates problems such as clogging of the spray nozzle or deflection of the spray direction due to clothing.Next, the operation of this embodiment will be explained in detail.The coating liquid is supplied from the liquid inlet 21 as a bath melt, and the coating liquid is supplied from the liquid inlet 21 as a bath melt. The liquid is ejected from the liquid ejection port 23 of the head 22. At that time, the coating liquid is atomized by the atomizing air blown out through the air passage 24 from the scaled air population 20, and is blown onto the object to be coated in the coaching pan 2, for example, as shown in Figure @1. At that time, the coating liquid flows through the liquid spout and the air passage 24.
However, in this embodiment, the spray nozzle of the nozzle head 22 is attached to the heating element. Since the coating liquid is heated above the melting point of the coating liquid, the deposits of the coating liquid that accumulate around the spray nozzle are maintained in a molten state by the heat from the heating element, and do not cool and solidify. 0 As a result, according to this embodiment, problems such as clogging of the spray nozzle with deposits of the coating liquid and deflection of the spray in one direction can be prevented, and a uniform footing can always be obtained. Note that a heater using a sheathed wire or the like may be used instead of the heating element 28ti nichrome edge.
