粉體雙斗定量包裝機，屬于粉體包裝機領域，包括機身框架、供料系統、送料系統、動力系統、稱重系統、物料過渡系統、夾袋系統、輸送縫包系統及底座，供料系統、送料系統及稱重系統依次設置，送料系統包括內部設有粗絞龍和細絞龍的雙絞龍箱，粗絞龍和細絞龍均位于相應的絞龍管內，雙絞龍箱內還設有位于絞龍管外側并用于封堵絞龍管上出料口的兩塊擋料板，擋料板通過第一氣缸控制機構驅動；輸送縫包系統包括用于密封包裝袋的縫包機構和用于輸送封口后袋裝物料的皮帶運輸機構。本發明集自動輸送、自動定量、半自動包裝等功能于一體，定量精度高，工作效率高，且不與人員直接接觸，可省時省力，還能保障粉體生產車間衛生。

摘要（英）：The invention discloses a double-hopper quantitative powder packaging machine, and belongs to the field of powder packaging machines. The double-hopper quantitative powder packaging machine comprisesa machine body frame, a material supply system, a feeding system, a power system, a weighing system, a material transition system, a bag clamping system, a conveying and package sewing system and a base. The material supply system, the feeding system and the weighing system are arranged in sequence. The feeding system includes a double-auger box internally provided with a thick auger and a thin auger, and the thick auger and the thin auger are both located in corresponding auger pipes. The double-auger box is further internally provided with two material baffles which are located on the outersides of the auger pipes and used for blocking discharging openings of the auger pipes, and the material baffles are driven by a first air cylinder control mechanism. The conveying and package sewingsystem comprises a package sewing mechanism used for sealing packaging bags and a belt conveying mechanism used for conveying packaged materials obtained after sealing. The double-hopper quantitativepowder packaging machine integrates the functions of automatic conveying, automatic quantifying, semi-automatic packaging and the like, is high in quantifying precision and working efficiency, does not make direct contact with personnel, can save time and labor, and can guarantee sanitation of a powder production workshop.
