Duckbilled mask manufacturing process and device

Abstract

The invention relates to a duckbilled mask manufacturing process and device. A mask comprises a mask upper face and a mask lower face. The manufacturing process comprises the following steps: foldingand press-sealing are performed on the upper nose edge on the mask and the lower jaw edge below the mask, and the nose bridge is added by adopting a double-path staggered cutting process while foldingthe upper nose edge; the mask upper face and the mask lower face are overlapped, convex edges of the mask upper face and the mask lower face are pressed and sealed after overlapping, a staggered opposite arrangement method is adopted for the mask in the pressing and sealing process, and a two-way staggered cutting process is adopted for completing adding of ear bands while the convex edges are pressed and sealed. The manufacturing process is a compound line type machining process, compound line edge folding, press sealing and stacking are conducted on all layers of materials, then a finishedproduct is cut, and manufacturing of the two duckbilled masks is completed at a time. A staggered opposite arrangement method is adopted, the spacing distance of the mask is shortened, the utilizationrate of bottom edge materials is high, and few waste materials are cut off around the mask.

Description

Technical field[0001]The invention relates to the technical field of rail transit control, and in particular to a manufacturing process and equipment of a duckbill mask.Background technique[0002]The three-dimensional mask adopts a three-dimensional structure design that matches the shape of the face, which can eliminate the gap between the mask and the sides of the nose, cheeks, and chin, which is not possible with ordinary flat masks. Three-dimensional masks mainly include duckbill masks, folding masks and cup masks.[0003]Duckbill masks are used to protect very small dust particles. The main feature is easy to fold and easy to carry. The electrostatically treated high-efficiency filter layer can effectively filter and absorb extremely fine harmful dust, which is suitable for various face shapes. The duckbill mask adopts a ship-shaped design with an adjustable nose clip line on the outside. The elastic band design is more in line with the mechanical requirements and has good airtigh...

Problems solved by technology

[0009] In order to solve the above-mentioned technical defects existing in the prior art, in the state of a sudden large-scale epidemic situation, the government's epidemic prevention and residents' protection have an urgent need for masks. The mask machine adopts a double-line processing technology, each layer of material is double-line folded, pressed and sealed, and the finished product is cut into a duckbill mask after superimposition
