The invention relates to an annular cellulose paper device with an airflow channel and a preparation method, and belongs to the technical field of suction products. The annular device is made by wrapping an inner layer of cellulose paper with an outer layer of cellulose paper and rolling the two around the same axis; the inner layer of cellulose paper is rolled, and then joints are tightly connected to form a closed inner ring; the outer layer of cellulose paper is rolled to form a closed outer ring to wrap the closed inner ring formed by the inner layer of cellulose paper. The direction of continuous operation of a paper tape is consistent with the direction of the axis, so that continuous paper feeding, continuous rolling and continuous cutting in a high speed state are achieved, and theprocessing speed rate of the annular device can be greatly increased. At the same time, the circumferential size of the annular device is determined by the width of the continuous paper tape, and thestability is great.
