[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, viruses, and droplets from entering and exiting the wearer's mouth and nose. Masks are mainly made of non-woven fabrics and gauze. Masks have a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in an environment polluted by dust.

[0003] Existing masks are generally produced automatically using mask production equipment. The mask production equipment manufactures various masks with certain filtering performance by hot pressing, folding, ultrasonic welding, waste cutting, ear strap, nose bridge welding and other processes of multi-layer non-woven fabrics. The mask equipment is not a single machine, it requires the cooperation of multiple machines to complete various different processes; the mask includes a mask body and ear strap lines, the ear strap lines are fixed on the mask body, and the function of the ear strap lines is to fix the mask body on the user's face to achieve the effect of filtering the air.

[0004] like Figure 1 As shown, for duckbill masks and head-mounted masks, the mask body is composed of multiple layers of materials welded and pressed together, but the internal breathing space of this mask is relatively small, and it is easy to cause hypoxia when worn for a long time. In addition, the multiple layers of materials are welded and pressed together, and the pressed boundaries are prone to cracking, causing damage to the mask. Summary of the invention

The feeding device 4000 is arranged on one side of a workbench, the nose bridge strip mounting device 5000, the preliminary pressing device 6000 and the forming and unloading device 7000 are arranged on the workbench, and the folding, pleating and pressing device 2000 and the ear band line conveying device 1000 are arranged vertically up and down on a frame 3000.

[0030] When producing masks, the mask layer materials are conveyed horizontally along the workbench on different cloth rollers of the feeding device 4000. During the conveying process of the mask layer materials, the nose bridge strip installation device 5000 installs the nose bridge strip on the mask layer materials, and then the preliminary pressing device 6000 preliminarily presses the mask layer materials. Then, the mask layer materials are folded and wrinkles are generated in the middle position through the folding and wrinkling pressing device 2000. The ear strap line conveying device 1000 installs the ear strap line in the middle of the mask layer materials in the middle of the folding and wrinkling pressing device 2000. After the ear strap line is installed, the molding and unloading device 7000 molds and cuts the mask. Through the above steps, masks are produced automatically, manual operations are reduced, and a one-piece duckbill-shaped mask with adjustable ear strap line length can be produced, with high production effect.

[0031] The feeding device 4000, the nose bridge installation device 5000, the preliminary pressing device 6000 and the forming and unloading device 7000 are similar to the existing mask machine structure. Example 1 provides a detailed description of the ear band line conveying device 1000.

The connection between the adjusting stud 132 and the first connecting seat 131 and the second connecting seat 133 can rotate. The second connecting seat 133 is fixedly connected to the bottom surface of the folding plate 110. The folding plate 110 is arranged downwardly tilted between the supporting component 120 and the adjusting component 130. The length of the adjusting stud 132 can drive the second connecting seat 133 to move, thereby changing the downward tilt angle of the folding plate 110.

[0037] The pleating assembly 200 includes a first shaping wheel shaft 210, a first support frame 220, a second shaping wheel shaft 230 and a second support frame 240. Both ends of the first shaping wheel shaft 210 are arranged on the first support frame 220, and both ends of the second shaping wheel shaft 230 are arranged on the second support frame 240. The first support frame 220 and the second support frame 240 are fixed on the fixing plate 600, and the shapes of the first shaping wheel shaft 210 and the second shaping wheel shaft 230 are meshed.

After passing through the conveying component 300, the mask fabric is transported to the folding component 100. The mask fabric is transported downward along the folding plate 110 of the folding component 100, thereby realizing the folding of the mask fabric. The mask fabric folded by the folding component 100 passes between the two shaping wheel shafts of the pleating component 200, and wrinkles are generated after rolling over the first shaping wheel shaft 210 and the second shaping wheel shaft 230. The middle part of the folded mask layer material forms wrinkles, and then is pulled downward by the second conveying component 500 and further pressed into shape.
