The utility model discloses a winding device and a winding machine. The winding device comprises a winding needle, a rotating shaft and a pressing mechanism, and the rotating shaft penetrates through the winding needle and can rotate synchronously with the winding needle; the pressing mechanism can rotate synchronously with the winding needle, the pressing mechanism comprises a pressing piece, and the pressing piece is arranged outside the winding needle; wherein the winding device has a winding state and a needle withdrawing state, and in the winding state, the pressing piece abuts against the winding needle, so that the material belt is connected with the winding needle; and in the needle withdrawing state, the pressing piece is separated from the winding needle, so that the material belt can move relative to the winding needle. The winding device can achieve the effect of non-stop winding of the material belt, and the production efficiency of battery cell winding is greatly improved. 本实用新型公开了一种卷绕装置及卷绕机。本实用
