Definitions

  • the invention belongs to the field of sanitary product device manufacturing, and specifically relates to a mask and a manufacturing process and device.
  • the mask must be of the right size and the way of wearing it must be correct for the mask's protective function to be effective.
  • Masks on the market are generally divided into rectangular and cup-shaped. Rectangular masks must have at least three layers of paper structure to have a protective effect. The user needs to press the iron wire of the mask on the bridge of the nose, and then spread the entire mask along the bridge of the nose to be effective. For cup masks, make sure that the density of the mask is sufficient after being attached to the face so that the exhaled air will not leak out to be effective.
  • the length of the ear straps is fixed. Because everyone's head size is not the same, the distance between the head and the ears is not the same. This often happens. Some people wear the same earband mask too tightly, and some people wear it too loosely. Wear an ear-band mask that is too tight, and the density of the mask is sufficient after being attached to the face, and the exhaled air will not leak out, and the mask has a protective effect; while wearing an ear-band mask that is too loose, the density after the mask is attached to the face Not enough, the exhaled air will leak out, and the mask does not have a protective effect.
  • strap-on masks have the advantage of being in use: the wearer can easily adjust the tightness of the straps by themselves, which can ensure that the mask has sufficient density behind the face and the exhaled air will not leak out. Make the mask have a protective effect. At the same time, the wearer can conveniently adjust the tightness of the strap by himself, which also maintains the wearing comfort of the wearer.
  • strap-on masks have another advantage when used: when the wearer cannot wear the mask himself, the strap-on masks can be easily worn by others for the wearer. This situation often occurs, such as when medical staff have equipment in their hands, or people with upper limbs or hands that are disabled.
  • strap-on masks have a large number of applications in production and life, it is undeniable that strap-on masks also have their specific shortcomings. Especially in the process of making strap-on masks, because the straps of strap-on masks are too long, too long straps are often wrapped around the mask machine. Therefore, the band-type mask cannot be automatically produced on the mask machine, and the band must be welded or sewn on the mask body manually, which wastes a lot of manpower and reduces the production efficiency of the band-type mask. At the same time, the welding or sewing of the straps on the mask body by human hands also increases the bacterial content of the mask, which increases the potential safety hazards when the mask is worn.

Abstract

La présente invention concerne un masque, comprenant un corps principal de masque et des sangles de fixation de masque sur deux côtés du masque, les sangles de fixation de masque étant formées par combinaison d'un tissu élastique et d'un tissu filé-lié, et étant pliées en une forme empilée. Le matériau d'une courroie de fixation utilise la propriété d'un tissu élastique ayant une élasticité relativement grande et la propriété d'un tissu filé-lié ayant une résistance relativement grande, de sorte que la courroie de fixation formée par combinaison des deux matériaux présente une certaine élasticité et une résistance relativement grande, et n'est pas facilement rompue pendant l'utilisation. La présente invention porte également sur un procédé et un dispositif de fabrication du masque. Un procédé de liaison de point et un dispositif de liaison de point sont utilisés, après pénétration des aiguilles de liaison de point à travers les matériaux, le matériau autour des trous d'aiguille de liaison de point est fondu légèrement et compacté, de sorte que la courroie de fixation ne se diffuse pas pendant la production du masque, ce qui permet de fabriquer des masques de type courroie de fixation dans une production industrielle.
