The invention discloses an aqueous synthetic leather production line. The aqueous synthetic leather production line is characterized by sequentially comprising, according to production procedures, a double-station release paper unwinding machine, a release paper joint table, a storage device, a first precision coating machine, a first drying oven, a double-roll cooling machine, a second precision coating machine, a first multi-layer fold back type drying oven, a multi-roll cooling machine, a stripping device, an edge cutting machine and a double-station winding machine, wherein the double-station winding machine comprises a product winding portion and a release paper winding portion. The aqueous synthetic leather production line is simple in arrangement and adaptive to aqueous synthetic leather production requirements, and mass production of aqueous synthetic leather can be realized. The drying oven is lengthened due to adoption of the 'fold back type drying oven', so that products can stay longer in the drying oven to adapt to drying and foaming characteristics of aqueous products. Further, production efficiency is improved, product quality can be guaranteed, occupied area is reduced, and cost reduction and efficiency improvement can be realized.
