Description

Technical Field

[0001] The utility model relates to the technical field of mask production equipment, and specifically to an adjustable mask edge sealing mold. Background Art

[0002] Masks are a kind of sanitary and epidemic prevention products. Generally, they are worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. They are made of gauze or paper and other materials. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing masks has a very good effect when working in dusty environments. Masks can be divided into air filtering masks and air supply masks. The dust blocking efficiency of masks is based on its blocking efficiency for fine dust, especially for respirable dust below 2.5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The dust blocking principle of gauze masks is mechanical filtration, that is, when dust hits the gauze, it passes through layers of barriers and blocks some large particles of dust in the gauze. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. Dust masks, whose filter materials are made of activated carbon fiber felt pads or non-woven fabrics, can block respirable dust particles smaller than 2.5 microns when passing through the filter material, thereby filtering the air.
