The invention discloses an environment-friendly and efficient UV paint spraying line. The environment-friendly and efficient UV paint spraying line comprises an
electric control cabinet, a first motor, an automatic dust removing device, a preheating device, a UV primer paint spraying device, a first tunnel, a UV finish paint spraying device, a second tunnel, a
UV curing device, a material driving belt, a second motor and a material storing box; and the first motor, the automatic dust removing device, the preheating device, the UV primer paint spraying device, the first tunnel, the UV finish paint spraying device, the second tunnel, the
UV curing device and the second motor are electrically connected with the
electric control cabinet, the material driving belt is arranged between the first motor and the second motor, and the automatic dust removing device, the preheating device, the UV primer paint spraying device, the first tunnel, the UV finish paint spraying device, the second tunnel and the
UV curing device are sequentially arranged from left to right and connected through the material driving belt. According to the environment-friendly and efficient UV paint spraying line and a technology thereof, UV paint is sprayed to a workpiece, and then a product which is high in surface
hardness,
wear resistance and glossiness is obtained.
