The utility model discloses an automatic pulp adding system of a flat screen embossing machine. The key points of the technical scheme adopted by the utility model are as follows: mechanical arms capable of longitudinally moving and vertically lifting up and down are mounted at the longitudinal top of the flat screen embossing machine; electromagnets are mounted on the heads of the mechanical arms; a pulp barrel, a pulp tank and a lifting hopper are mounted each embossing screen frame side; a hinge is mounted at a part, away from the opening edge, of the outside of the lifting hopper by a height being larger than one half; a lifting handle is mounted on the hinge; a small ring is mounted on the opposite side of the lifting hopper hinge; a guide rod is fixed on the pulp tank; the guide rod is sleeved into the small ring of the lifting hopper and is put into the pulp barrel; a cloth length counting sensor is mounted on the flat screen machine; the mechanical arms attract the lifting handle to add the pulp when the embossed cloth reaches a certain length according to the designed program. The system can be used for replacing manual pulp adding; the pulp is added at a right time according to the length of the embossed cloth, thereby preventing the pulp from being added excessively or insufficiently; a plurality of embossing machines can be controlled by one worker.
