Full-automatic mask production line

Abstract

The invention discloses a full-automatic mask production line. The production line comprises a machine frame, a mask fabric edge banding device, a mask surface folding device, a mask transverse sealing cutting device and an ear strip welding device; the mask fabric edge banding device comprises a fabric feeding device, a fabric edge folding device, a fabric splicing device, a fabric drawing mechanism and a nose bridge strip feeding device, the fabric edge folding device comprises a lower supporting plate and an upper pressing plate, the upper pressing plate is arranged above the lower supporting plate, two side edges of the lower supporting plate are provided with multiple edge folding side plates which are sequentially arranged from front to back, a nose bridge strip flowing pipe is arranged between the backmost edge folding side plate and the upper pressing plate, and the discharging port of the nose bridge strip feeding device faces the front end of the nose bridge strip flowing pipe; the fabric splicing device comprises a splicing motor, a first ultrasound mold, a rotary shaft, a first splicing wheel and a second splicing wheel, a strip-shaped groove is formed in the circumferential surface of the first splicing wheel, and the strip-shaped groove faces the rear end of the nose bridge strip flowing pipe. By means of the mask production line, edge banding process of fabrics can be automatically completed, and the nose bridge strip is accurately added into the edge banding parts of the fabrics.

Description

technical field [0001] The invention relates to mask production equipment, in particular to a fully automatic mask production line. Background technique [0002] The mask is mostly set in a rectangular shape, and a nose bridge strip is set in the mask (the nose bridge strip is a thin plastic strip that can be bent and deformed), so that when the mask is worn, the nose bridge strip can fix the mask on the bridge of the nose, so that the mask more comfortable to wear. [0003] Existing a kind of mask production line comprises frame, mask cloth edge banding device, mask face folding device, mask horizontal sealing and cutting device and ear band welding device, mask cloth edge sealing device, mask face folding device, mask horizontal sealing and cutting device and ear strap The belt welding device is installed on the frame sequentially from front to back. When working, the mask fabric is first sealed by the mask fabric edge sealing device, and the nose bridge is added to the ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned mask cloth edge banding device can automatically complete the edge banding process to the mask cloth, and add the bridge of the nose in the cloth of the mask, the relative position of the bridge of the nose with the cloth of the mask is easy to move when the bridge of the nose moves under the drive of the cloth of the mask. The offset occurred, which caused the fabric welding device to fail to weld the hemming part of the mask fabric smoothly, which affected the edge sealing quality of the mask
