Flattening device for mask production and processing

The utility model relates to the technical field of medical supply production, in particular to a flattening device for mask production and processing, which comprises a mounting shaft, a hot pressing plate, a cold pressing plate and sliding adjusting mechanism groups, the sliding adjusting mechanism groups are symmetrically mounted on the mounting shaft in a sliding manner, and the hot pressing plate and the cold pressing plate are mounted below the sliding adjusting mechanism groups in a sliding manner. By designing the hot pressing plate and the cold pressing plate, the hot pressing plate and the cold pressing plate are separated, secondary flattening, primary hot pressing and primary cold pressing are achieved, the pressing plate device is combined with the cold and hot flattening technology, the flattening efficiency of mask materials is higher, the flattening effect is better, by additionally arranging the design processing structure of the folded plates and the arc-shaped chamfers, the plate bottom is
