Serial type double-surface extrusion coating machine

The embodiment of the invention discloses a serial type double-surface extrusion coating machine, aiming at solving the problems that as an existing extrusion single-surface coating machine needs at least twice reeling and unreeling to finish double-surface coating, physical or chemical performance of a base material is likely to change, the efficiency is low, and the energy consumption is high. The serial type double-surface extrusion coating machine comprises an unreeling component, a first coater, a dual-surface drying oven, a second coater, a traction component and a reeling component, wherein an unreeling opening of the unreeling component, a coating head of the first coater, a first layer of drying channel of the dual-surface drying oven, a coating head of the second coater, a second layer of drying channel of the dual-surface drying oven, the traction component and a reeling inlet of the reeling component form a coating channel for conveying a base material by a plurality of guide rollers in sequence.
