Description

Manufacturing equipment and method of flat three-dimensional mask

The invention relates to the field of daily masks, in particular to a manufacturing equipment of a flat three-dimensional mask and a method for manufacturing a mask using the manufacturing equipment.

When wearing a mask, in addition to the filtering performance of the mask material, the tightness between the face and the mask must also be considered when wearing the mask. If the tightness is insufficient, harmful substances may enter through the gap between the mask and the user's cheek. The mask is inhaled by the user's mouth and nose, losing its effect of protecting the user.

Please refer to FIG. 14, which shows the longitudinal section of the conventional flat mask, which is generally made of non-woven lamination materials by sewing. The mask body 90 is mainly divided into at least one barrier layer 92 and a corrugated portion 93. The nose bridge strip 91 is arranged in one of the upper folds of one end of the barrier layer 92. The tightness between the mask body 90 and the user's face; the wrinkled portion 93 is used to increase the area where the mask body 90 covers the user's mouth and nose; when in use, lightly press the nose bridge strip 91 to make the mask body 90 close to the user's nose bridge. Then, press the upper edge of the mask body 90, stretch and unfold the wrinkled portion 93, and wrap it to the lower jaw, so as to increase the protective area of the mask body 90.

The wrinkled part 93 of the conventional mask has the opening 94 downward. Due to the characteristics of the fiber material, when the wrinkled part 93 is stretched and unfolded, there is an elastic tendency to open outward, and it is not easy to fit closely with the user's face. Furthermore, since the curve of the human face is curved rather than flat, the folded portion 93 with the downward opening is likely to form a gap with the user's cheek, which cannot provide good adhesion and wrapping.

Furthermore, due to the poor adhesion and coverage of the conventional mask, the nose bridge bead 91 made of steel wire is pressed on the bridge of the user's nose, and the effect of maintaining the adhesion between the mask body 90 and the user's cheeks is still high. There are deficiencies, especially when the covering pressure is directly pressed to the nose tip with the highest bulge, wearing the mask for a long time will cause discomfort to the user.

The inventor of this case has previously developed a flat three-dimensional mask in view of the shortcomings of the conventional flat mask, and filed a patent application on record, the patent application number: 109111556. The flat three-dimensional mask has a wrinkled part with an upward opening. When the wrinkled part is stretched and unfolded, it has an elastic tendency to close inwardly, so that the edge of the mask body is easier to fit closely with the user's cheek, providing good Adhesion and coverage. Usually, the mask is in the shape of a flat mask, which has the advantages of small size after being folded, and easy to carry and store; when worn on the user's face, the mask presents the shape of a three-dimensional mask, which is very difficult for particles. The filtering effect is better than that of flat masks, and it does not cover the mouth and nose, so it has a larger breathing space. When worn for a long time, the comfort is better than that of flat masks.

However, the current conventional mask manufacturing equipment can only produce conventional flat masks, and cannot produce the above-mentioned novel and practical flat three-dimensional masks, and the existing automatic mask production line has a complex structure and low production efficiency, generally only 60-80 pieces per minute. , Due to the complex structure and large error between settings, the product yield is low.
