Nozzle rotation mechanism and application device therewith

摘要

Disclosed is a nozzle rotation mechanism that is small in size, has a simple structure, and can accurately adjust the rotational direction of a nozzle tip. Also disclosed is a coating device provided with the aforementioned nozzle rotation mechanism. The nozzle rotation mechanism is provided with: a nozzle having a discharge outlet from which a liquid material is discharged; a nozzle unit having a channel that connects the nozzle and a liquid material supply source; a base member; and a rotation device that is provided on the base member and rotates the nozzle unit. The nozzle is disposed in the nozzle unit such that the centerline of the discharge outlet of the nozzle forms an angle with the rotational centerline of the nozzle unit, and the nozzle unit is removably mounted to the rotation device.
