An intelligent manufacturing system for making cleaning sheet includes a multi-stage drying apparatus and a continuous track with non-stick coating. The drying apparatus has at least two stages and a lifting roller arranged between the two stages of the drying apparatus. The continuous track is at its exterior surface coated with the non-stick coating or covered by a medium having the non-stick coating, so that the manufactured cleaning sheet can have active cleaning ingredients therein protected and be easily removed from the continuous track after being dried. The lifting roller between the two stages of the drying apparatus prevents the adhesion between adjacent layers in the rolled cleaning sheet. The intelligent manufacturing system also has an enzyme-adding apparatus for spraying active enzyme that increases cleaning capacity onto the dried cleaning sheet so as to ensure the enzyme to retain good activity.
