In 2020, affected by the COVID-19, there was a dilemma that a mask was difficult to find and the price soared due to the shortage of masks, and the market demand for masks soared. Today we mainly introduce the classification of masks and the operation of the automatic mask making machine.
Ordinary cotton masks, disposable masks (such as medical surgical masks), N95 masks
1) Disposable Masks (Medical Surgical Masks)
It can prevent respiratory infections, but cannot prevent haze. Medical surgical masks, which is produced by surgical mask making machine, have three layers, they are the waterproof layer, the filter layer, and the comfort layer from the outside to the inside. The comfort layer is a layer made of non-woven fabric. When wearing, the white non-woven fabric is facing inward, the blue waterproof layer is facing outwards, and the side with the metal sheet is facing up. Do not wear it backwards. Hook the rubber band on the ears and then pinch the metal sheet, so that there is no gap between the mask and the face. Pay attention to the words "Medical Surgical Mask" clearly marked on the outer packaging when buying this type of masks.
2) N95 Masks
It can effectively prevent respiratory infections and prevent haze. The N95 mask is one of the 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). "N" means unsuitable for oily particles (the fume produced by cooking is oily particles, while the droplets produced by people talking or coughing are not oily). "95" means that under the testing conditions specified by the NIOSH standard, the filtering efficiency reaches 95%. N95 masks are produced by n95 mask making machine. N95 is not a specific product name. As long as the products meet the N95 standard and pass the NIOSH review, they can be called "N95 masks".
3) Ordinary Cotton Masks
Its material may be cotton, gauze, wool, canvas and velvet, etc. Because the material itself is not dense enough, it cannot prevent infection.
The automatic flat mask making machine makes various masks with certain filtering performance through processes such as hot pressing, folding and forming, ultrasonic welding, waste removal, and welding of ear straps and nose bars. The automatic flat face mask making machine is not a single machine. It requires the cooperation of multiple machines to complete various processes. The popular automatic facial mask making machine in the market include: cup mask making machines, non-woven flat mask making machines, N95 mask making machines, 3M9001/9002 folding mask making machines, duckbill mask making machines, and three-dimensional dust-proof mask making machines.
The flat automatic ultrasonic mask making machine uses ultrasonic welding. When the mask is moved to the processing position, ultrasonic waves are automatically generated, forming micro-amplitude and high-frequency vibrations on the ear straps, which are instantly converted into heat, melting the material to be processed, and finally making the ears strap permanently pasted or embedded on the inside of the mask. Only one operator is required to place the mask piece by piece in the mask tray.
The working process of fully automatic mask making machines: manual feeding → automatic ear strap feeding → ultrasonic ear strap welding → non-woven side strap feeding and edging → ultrasonic side strap welding → side strap cutting → finished product output → counting →finished product stacking→conveyor belt device sending out.
