Automatic pay -off smoke generating device

The utility model discloses an automatic pay -off smoke generating device, including automatic feeding, flue gas happening box and support frame, be equipped with the feed inlet on the flue gas happening box, automatic feeding's guiding mechanism includes screw rod sliding block subassembly and guide rail, and the scraping wings is fixed on the slider, and actuating mechanism drive slider removes,material pipe parallel mount is in one side of guide rail, and the guide groove that the scraping wings leads to on the feed tube gets into the intraductal propulsion cake of material at material move within the barrel. Through flue gas happening box upper feeding port and the butt joint of material pipe, and make material pushing sheet's feed rate evenly controllable under actuating mechanism and screw rod sliding block transmission mode's cooperation, autoloading has not only been realized, and the fume emission volume is evenly controllable, more real fire smoke simulation effect has beenreached, simultaneously be
