The invention discloses a granular material packaging device. The granular material packaging device is an automatic packaging device and comprises a stander and a control mechanism, wherein the control mechanism is arranged on the stander and is in signal connection with a packaging mechanism, a paper conveying mechanism and a material storage mechanism which are arranged on the stander; the material storage mechanism is arranged above the packaging mechanism, the paper conveying mechanism is arranged behind the packaging mechanism, and an intermittent mechanism for conveying granular materials to the packaging mechanism is arranged between the material storage mechanism and the packaging mechanism. By virtue of the structural form, the time of coiling a single granular material is greatly shortened, and the volume of the single granular material is reduced as well; and the granular material packaging device is suitable for coiling granular materials differing in diameters and lengths, and non-returnable packaging is realized; and the granular material automatic packaging device is simple and compact in structure and worthy of being popularized and applied.
