This invention discloses a method for analyzing the propagation path of anomalies in PE blow molding production, relating to the field of production path technology. It addresses the issues of fluctuating film structural performance and unstable product quality. By reshaping the circumferential angle of the film bubble, collecting the zoned current of the air ring drive motor and the outlet pressure of the air duct in each region to assess the air duct blockage trend, and triggering a propagation analysis mechanism when a blockage trend exists, the method obtains the circumferential temperature distribution of the film bubble and constructs temperature hysteresis characteristics based on the rotation speed.
