The invention relates to a charging packaging device separating two powder materials; the bottom of a bracket is provided with an electrical control box and a paper cutting mechanism; the middle part of the bracket is provided with a paper distance adjusting and conveying roll shaft and an output mechanism; the bracket is provided with a powder feeding mechanism formed by a pulling tray base, a pulling tray, a sliding block, a space rocker, a rotating pair, a space connecting rod, a crank rotating shaft, a gear and a pulling tray valve, and a clamping roller; and a guide bracket is provided with a double-body material box, and three rolls of paper can be used for packaging. The charging packaging device separating two powder materials has the advantages that a space rocker mechanism is adopted to lead rotating movement of a roller main shaft into straight line movement of a pulling tray mechanism; the material box can be fed with double materials; the same packaging bag can be used for packaging two different powder substances in a separating way; and the device has the advantages of simple structure and fewer parts, is flexible in running and high in accuracy, saves the packing material, has very convenient use, and can adapt to the needs of new package of the market.
