Developing agent spraying device for three-dimensional scanning

The utility model relates to the technical field of three-dimensional scanning, in particular to a developer spraying device for three-dimensional scanning. Comprising a motor box, a motor is fixedly installed in the motor box, a motor output shaft of the motor penetrates through the top of the motor box to be connected with a three-jaw chuck, an atomization spray gun is installed above the three-jaw chuck, a powder inlet connector and an air inlet connector are arranged on the atomization spray gun, and the air inlet connector is located above the powder inlet connector. A workpiece mounted on the three-jaw chuck rotates at a constant speed, so that a uniform spraying effect is achieved; in addition, the atomizing spray gun can rotate at any angle on the mounting frame, so that complete covering type spraying on the workpiece is realized, and omission is prevented. 本实用新型涉及三维扫描技术领域，尤其涉及一种用于三维扫描的显像剂喷涂装置。包括电机箱，所述电机箱内固定安装有电机，所述电机的电机输出轴穿过所述电机箱的顶部连接三爪卡盘，所述三爪卡盘的上方安装有雾化喷枪，所述雾化喷枪上设有进粉接口和进气接口，所述进气接口位于所述进粉接口的上方。安装在三爪卡盘
