A kind of duckbill mask manufacturing process and equipment

Abstract

The invention relates to a manufacturing process and equipment for a duckbill mask. The mask includes an upper face of the mask and a lower face of the mask; The bridge of the nose is added by using a two-way dislocation cutting process while folding the edge; the top of the mask is superimposed on the bottom of the mask, and after the superimposition, the convex edges on the top of the mask and the bottom of the mask are pressed and sealed. At the same time, the two-way dislocation cutting process is used to complete the addition of ear straps. The manufacturing process of the present invention is a double-line processing process, and each layer of material is double-line folded, pressed and sealed, and the finished product is cut after stacking, and the production of two duckbill masks is completed at one time. The invention adopts the dislocation facing arrangement method, which shortens the interval distance of the masks, realizes high utilization rate of the bottom edge material, and reduces waste materials cut off around the masks.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a production process and equipment for a duckbill mask. Background technique [0002] The three-dimensional mask adopts a three-dimensional structure design that matches the shape of the face, so that the gap between the mask and the sides of the nose, cheeks, and chin can be eliminated, which is impossible for ordinary flat masks. Three-dimensional masks mainly include duckbill masks, folding masks and cup masks. [0003] Duckbill respirator for protection against very small dust particles. The main feature is that it is easy to fold and easy to carry. The electrostatically treated high-efficiency filter layer can effectively filter and absorb extremely fine harmful dust, and is suitable for various face shapes. The duckbill mask adopts a boat-shaped design, and there is an adjustable nose clip line on the outside. The elastic band design is more in line with the...
