Summary: | The utility model belongs to the technical field of moistening and coating devices, and particularly relates to a moistening and coating device for moistening and coating a roll film for packaging with smooth liquid. Comprising a rack, an unwinding part which is fixed on the rack and is used for unwinding a roll film, a coating mechanism which is arranged on one side of the unwinding part and is used for coating the roll film with a smooth liquid, a drying box which is arranged on one side of the coating mechanism and is used for drying the smooth liquid on the roll film, and a winding part which is fixed on the rack and is used for winding the dried roll film. According to the utility model, the prepared smooth liquid is uniformly coated on the inner surface or the outer surface of the roll film, of which the friction coefficient needs to be changed, through the coating mechanism, and meanwhile, an organic solvent in a smooth liquid system can be completely removed through the drying box; only erucyl amide o |
