The invention relates to the field of face mask production equipment, in particular to a face mask body making machine. The face mask body making machine comprises a feeding mechanism, a frame, a printing mechanism, a fixed nose bridge strip mechanism, a pattern mechanism, a cutting mechanism, a waste material collecting mechanism and a discharging mechanism, wherein the feeding mechanism is used for feeding non-woven fabrics and nose bridge strips; the printing mechanism is used for printing on the non-woven fabrics; the fixed nose bridge strip mechanism is used for welding the nose bridge strips on the non-woven fabrics; the pattern mechanism is used for molding patterns on the non-woven fabrics; the cutting mechanism is used for cutting corners of the non-woven fabrics on which the patterns are molded; the waste material collecting mechanism is used for recovering waste scraps; the discharging mechanism is used for discharging finished face masks; the printing mechanism, the fixed nose bridge strip mechanism, the pattern mechanism, the cutting mechanism, the waste collecting mechanism and the discharging mechanism are all arranged above the frame, and are all positioned behind the feeding mechanism. The face mask body making machine has high production efficiency, and has contribution to improvement of the face mask quality.
