Mask forming machine

Abstract

The invention relates to mask production equipment, in particular to a mask forming machine which comprises a rack, a non-woven fabric unwinding device, a forming device and an output device. The non-woven fabric unwinding device, the forming device and the output device are arranged on the rack; the forming device comprises a first guide assembly, a folding assembly, a nose bridge strip adding assembly, a composite roller assembly, a second guide assembly and a slitting assembly; the folding assembly comprises an indentation roller, a folding frame and a shaping mechanism; the nose bridge strip adding assembly comprises a nose bridge strip unwinding roller, a nose bridge strip guide roller assembly, a nose bridge strip conveying assembly, a nose bridge strip cutter assembly and a nose bridge strip guide pipe; the length of the nose bridge strip guide pipe is smaller than the length of a cut nose bridge strip; the composite roller assembly comprises a composite roller, a welding head and an ultrasonic generator; and the slitting assembly comprises an upper slitting roller and a bottom slitting roller. Non-woven fabric and the nose bridge strip can be conveyed to the forming deviceat the same time, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to mask production equipment, in particular to a mask forming machine. Background technique [0002] At present, most small-scale manufacturers of masks do not have fully automatic mask production lines. During the forming process of traditional mask pieces, the bridge of the nose is inserted between the upper and lower layers of fabric from perpendicular to the direction of travel (horizontal) of the mask piece. , and then the upper and lower layers of cloth are bonded together by the forming roller and the ultrasonic device matched with the forming roller. In the actual production process, the upper and lower layers of fabric and the bridge of the nose are sent to the forming station separately, that is, after the upper and lower layers of fabric arrive at the forming station, it is necessary to wait for the horizontal insertion of the bridge of the nose, thereby reducing production efficiency.
