Mask sheet forming machine

Abstract

The invention discloses a mask sheet forming machine capable of simultaneously conveying upper-layer cloth, lower-layer cloth and nose bridge strips to a forming station and realizing automatic stripping. The mask sheet forming machine comprises an unwinding device, a forming device and a stripping device, wherein the forming device comprises a forming rack, a feeding device, a before-forming feeding device, a forming roller and an after-forming pulling device, wherein the feeding device, the before-forming feeding device, the forming roller and the after-forming pulling device are arranged onthe forming rack; an ultrasonic device is arranged below the forming roller; the feeding device comprises an upper-layer cloth guiding device, a nose bridge strip guiding and fixed-length cutting device and a lower-layer cloth guiding device; the stripping device comprises a discharging rack and a stripping rack, wherein the discharging rack is provided with a discharging device, and the discharging device comprises a discharging rod and a discharging blocking roller matched with the discharging rod, and a discharging guide roller matched with the discharging blocking roller is movably arranged in the middle of the discharging rod; and a scrap edge winding device is arranged at the upper part of the stripping rack. An insertion direction of the nose bridge strip is changed, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to mask production equipment, in particular to a mask piece 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. In addition, after the mask...

Problems solved by technology

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

In addition, after the mask sheet is pressed and formed, the waste materials on both sides are usually torn off manually.

In doing so, it not only increases the labor cost, but also reduces the production efficiency.
