Method for dynamically judging precision exception of winding drum of reeling machine

A method for dynamically judging precision exception of a winding drum of a reeling machine aims to find out a degradation phenomenon of the winding drum of the reeling machine timely. The method comprises the steps as follows: starting a wrapper roller of the reeling machine, and listening whether the winding drum makes a periodic sound; observing the monitoring picture of a man-machine interface of an operating board of the reeling machine; during the zero-calibration process, listening to the contact sound of the wrapper roller and the winding drum of the reeling machine on site; after the zero-calibration process, starting the wrapper roller of the reeling machine quickly, adjusting the roll bite of the wrapper roller capable of programming an automatic controller to minus 1 mm, and listening to the contact sound of the winding drum and the wrapper roller; after the zero-calibration process, starting the wrapper roller of the reeling machine quickly, adjusting the roll bite of the wrapper roller capable o
