The first coating unit 52 is a solvent-free coating unit, and the second coating unit 12 and the third coating unit 22 are both anilox roller coating units.

[0049] like Figure 18 As shown, the solvent-free two-in-one composite dual-machine process is as follows: the first film material of the first unwinding unit 51, after passing through the first coating unit 52 and the first oven, is laminated with the fifth film material of the fifth unwinding unit 43 at the first composite unit 42 to form a two-layer composite film, and then wound up in the second winding unit 44. The fourth film material of the fourth unwinding unit 21, after passing through the third coating unit 22 and the third oven 9, is laminated with the sixth film material of the sixth unwinding unit 34 at the second composite unit to form a two-layer composite film, and then wound up in the first winding unit 33. The first coating unit 52, the second coating unit 12, and the third coating unit 22 are all solvent-free coating units.

[0050] The first, second, and third coating stations can all be easily operated by changing the coating unit to quickly switch between various coating methods such as solvent-free coating and anilox roller coating. One machine can complete multiple four-in-one processes, reducing production costs.
