The invention dislcoses a rotary label bagging device. The rotary label bagging device comprises a material bag index plate, a material core index plate and a bag opening and core pushing mechanism, the material bag index plate is used for containing material bags, the material core index plate is used for containing material cores, and the bag opening and core pushing mechanism is used for opening the material bags and pushing the material cores into the material bags, the bag opening and core pushing mechanism comprises a bag pressing mechanism, a bag opening mechanism and a core pushing mechanism, the bag pressing mechanism, the bag opening mechanism and the core pushing mechanism are located above the connecting line position of the circle center of the material bag index plate and the circle center of the material core index plate, the bag pressing mechanism is used for pressing the front ends of bag openings of the material bags, the bag opening mechanism is used for opening the bag openings of the material bags, and the core pushing mechanism is used for pushing the material cores into the material bags. According to the rotary label bagging device, the material bag index plate, the material core index plate, the bag opening and core pushing mechanism and the like are arranged, so that the material cores are loaded into material bags, automatic bagging of labels is realized, the automation degree is high, and the bagging efficiency is high.
