Abstract
The invention discloses a powder spraying machine. A top replacing type automatic cleaning device is arranged at the top of an inner cavity. Multiple infrared lamps are arranged on the side wall of the inner cavity. Spraying heads downwards spray out mist containing a solvent and middle powder. The mist is directly irradiated and heated by infrared light emitted by the infrared lamps, the solvent in the mist is heated to gasify and expand towards the two ends, and thus the middle powder contained in the mist is dried and evenly scattered. A conveying mechanism is arranged at the bottom of the inner cavity, and a product on the conveying mechanism enters the inner cavity from an inlet and is conveyed out from an outlet. The parts which are arranged at the two ends of the inner cavity and located below the conveying mechanism are each provided with a row of transverse exhaust openings, and the transverse exhaust openings are communicated with an exhaust fan through exhaust pipes. The heated and gasifying solvent is exhausted from the transverse exhaust openings after expanding towards the two ends, and part of the middle powder which does not settle on the product is also exhausted through the transverse exhaust openings. The powder spraying machine has the beneficial effects of being good in machine washing effect, short in time, low in energy consumption and capable of lowering the loss amount of the middle powder.
