The invention provides a planetary-type double-station automatic bagging device. In the working process of the planetary-type double-station automatic bagging device, protective bags are manually placed on conveying roller ways, and a clamping device automatically conducts positioning and clamping on the protective bags; and meanwhile, a feed mechanism on a guiding rail pushes positive plates intothe sleeved protective bags, the positive plates after bagging is conducted are conveyed to the next procedure through the conveying roller ways, finally a planetary-type double-station rotating mechanism rotates by 180 degrees so as to transform the positions of the two conveying roller ways, and station circulation is achieved.
