Automatic production line of polyimide film and automatic production method thereof

The invention provides an automatic production line of a polyimide film and an automatic production method of the polyimide film, and relates to the field of polyimide film processing.The automatic production line comprises a shell breaking mechanism and a sorting mechanism, a prepared polyamide acid solution is enabled to enter a device inner cavity through the edge of a disc body, and the polyamide acid solution is shunted to enter an inner cavity of a tandem column; a spiral rod body is spirally matched with an assembling cylinder, an inner cavity of the spiral rod body and the assembling cylinder is filled with a polyamide acid solution, the space between the spiral rod body and the assembling cylinder is gradually reduced, the pressure intensity of the inner cavity is gradually increased, the polyamide acid solution is hydrolyzed under high pressure intensity, and a connecting gear ring is meshed with an assembling gear ring, so that the processing cylinder and the assembling cylinder are connected in se
