粉体双斗定量包装机，属于粉体包装机领域，包括机身框架、供料系统、送料系统、动力系统、称重系统、物料过渡系统、夹袋系统、输送缝包系统及底座，供料系统、送料系统及称重系统依次设置，送料系统包括内部设有粗绞龙和细绞龙的双绞龙箱，粗绞龙和细绞龙均位于相应的绞龙管内，双绞龙箱内还设有位于绞龙管外侧并用于封堵绞龙管上出料口的两块挡料板，挡料板通过第一气缸控制机构驱动；输送缝包系统包括用于密封包装袋的缝包机构和用于输送封口后袋装物料的皮带运输机构。本发明集自动输送、自动定量、半自动包装等功能于一体，定量精度高，工作效率高，且不与人员直接接触，可省时省力，还能保障粉体生产车间卫生。

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.
