Abstract

The utility model provides a spraying system, which comprises a magazine for supplying coating, wherein the magazine is suitable to be detachably ingathered by a rotating cup, thereby being convenient to replace the magazine. Based on the detachable configuration of the rotating cup and the magazine, (1) new coating can be prevented from mixing with old coating when replacing coating, simultaneously a material supply pipeline which is arranged between a color changing valve and an atomizer is prevented from cleaning, thereby saving coating and solvent. (2) Because the rotating cup just ingathers specific magazines, the design of a pipeline and a pump between a coating tank and the color changing valve is prevented, thereby increasing the number of the species of the coatings. (3) A conductive path which is arranged between the coating tank and the rotating cup is cut, thereby being capable of directly charging for waterborne coatings.
