Ultrasonic welding on the non-woven fabric dust mask
In recent years, the most popular collapsible duckbill-type dust mask on the market is made of activated carbon fiber, activated carbon granules, melt-blown fabric, non-woven fabric, electrostatic fiber, etc. The six-layer material is made by ultrasonic welding. The unique design of the mask and the ultrasonic welding process have a three-dimensional effect. The high-performance melt-blown material filtration of the multi-layer non-woven fabric can effectively prevent dust and non-oily particles in the air. When choosing a mask, we should look at the fact that the design of the mask at the beginning of the mask is not high enough for our face. Only the mask that fits the face can better separate our nose and mouth from the air. Open, so we should choose those masks that have a high rate of fit on our face. To achieve a face and mask fit, this is directly related to the ultrasonic welding mold formed by the mask. This new type of mask will have a strong market share due to the simple manufacturing process and practical factors. The production process has six layers of non-woven fabric conforming, three-dimensional mask forming, ear strap welding and plastic breathing valve welding. All are made by ultrasonic welding machines. It is a machine that uses the principle of ultrasonic seamless welding to produce a duckbill-shaped mask suitable for high-pollution industrial use. The machine body part of the machine can use 4~10 layers of PP non-woven fabrics and filter materials (such as meltblown cloth, activated carbon materials, etc.), so that masks of various filter grades such as N95 and FFP2 can be produced. Semi-automatic and automated machines can be used, and the automation of this machine is extremely high. From the incoming material to the finished product, it is a line of automatic operation: automatic feeding of raw materials, independent nose conveying system, and automatic folding of the nose line. Inside the woven fabric, automatic hem and finished cut, and the breathing valve hole can be automatically attached. The finished product produced by the duckbill-shaped mask machine has beautiful appearance; the machine has stable performance, high output, low defect rate and easy operation.
