  "textContent": "Embodiments of the present application provide a variable-diameter adsorption winding needle mechanism (100) and a winding machine, which relate to the technical field of lithium cell manufacturing. The variable-diameter adsorption winding needle mechanism includes a winding needle assembly (110), a first adsorption winding needle (130), a second adsorption winding needle (150) and a pin assembly. A plurality of adsorption holes (190) are provided on the outer peripheral surfaces of the first adsorption winding needle (130) and the second adsorption winding needle (150). At the same time, the winding needle assembly is also used to drive, under the driving of the pin assembly, the first adsorption winding needle (130) and the second adsorption winding needle (150) to move close to or away from each other. Compared with the prior art, in the variable-diameter adsorption needle mechanism provided by the present application, the head of the material tape is absorbed through the plurality of adsorption holes, thereby avoiding that the material tape passes through the winding needle to achieve the clamping, and can realize that the winding needle is changed for performing the winding without stopping the material tape, which further improves the production efficiency of the winding machine; and at the same time, the winding diameter of the winding needle head can also be automatically adjusted, so that the winding head achieves the automatic changing of the diameter in the situation that the dislocation of the tabs are automatically adjusted, wherein the dislocation of the tabs is adjusted in the unmanned operation, improving the equipment efficiency and the utilization rate.",
