The invention provides a tape-adaptive winding mechanism. The winding mechanism comprises a hot pressing roller, a translation device and an angle control and measure device, wherein the hot pressing roller has a hollow cylindrical structure; the translation device comprises a step motor, a screw and nut mechanism, a linear slide rail and a slide block; the angle control and measure device comprises cylinders and an angle measurer; the cylinders drive the hot pressing roller to deflect; a support plate is fixed on a fixing plate; the end portion of the support plate is provided with the angle measurer; the angle measurer comprises a potentiometer, a connection shaft and a support frame; the connection shaft connects the potentiometer with the hot pressing roller; and the hot pressing roller drives the connection shaft to rotate when the hot pressing roller deflects. The winding mechanism enables the hot pressing roller to adaptively fit to the surface of a winding part through the driving of the deflection of the hot pressing roller by the cylinders, and the compensation amount of front point positions of the hot pressing roller to be determined through measuring the deflection angle of the hot pressing roller, and controls the step motor to drive the whole body to move, so the front point positions of the hot pressing roller always maintain unchanged.
