The utility model relates to a four-in-one and series connection
production line with selective combination of a flat position dry method and a
solvent-free
composite process, which sequentially comprises a first unit, a second unit, a third unit, a fourth unit and a fifth unit from left to right, the first unit comprises a first unwinding unit, a first
coating unit and a first compounding unit, the second unit comprises a first unwinding unit, a first
coating unit and a first compounding unit, the third unit comprises a first winding unit, a second compounding unit and a third compounding unit, the fourth unit comprises a fourth unwinding unit and a third
coating unit, and the fifth unit comprises a third unwinding unit and a second coating unit. A first
drying oven is arranged on the second connecting plate, a second
drying oven is arranged on the third connecting plate, and a third
drying oven is arranged above the second drying oven. By selectively starting the coating unit and the drying oven and replacing different coating units, a dry method and a
solvent-free four-in-one compounding process can be freely switched, meanwhile, two-in-one compounding of series-connection double machines can be realized, the production cost is reduced, and the equipment
utilization rate is improved.
