Three-dimensional mask beneficial to rapid and automatic production and production method thereof

Abstract

The invention provides a three-dimensional mask beneficial to rapid and automatic production and a production method thereof. The three-dimensional mask is characterized in that after being unfolded, a mask body comprises a left section and a right section which are integrated in the left-right direction and are symmetrically distributed, elastic bands are symmetrically arranged on the outer side faces of the left section and the right section and are U-shaped bodies, and opening parts of the U-shaped bodies are connected to the edges of the left section and the right section; the orientation of the opening parts of the U-shaped bodies is parallel to the symmetrical line of the left section and the right section; and each elastic band comprises a pair of laminated non-woven fabrics and a plurality of rubber bands or elastic spandex filaments or shrink films which are transversely distributed in the non-woven fabrics at intervals. The continuous elastic base material layer can be quickly formed and conveyed on a production line during production to generate the U-shaped bodies, and the U-shaped bodies are automatically connected to the mask body through ultrasonic welding, so that automatic and quick production is facilitated, the production efficiency can be greatly improved, the production time is shortened, and time and labor are saved; and the blowout type requirement on the mask due to sudden social public health and safety incidents can be greatly relieved.

Description

technical field [0001] The invention relates to the technical field of medical and sanitary products, in particular to a three-dimensional mask and a production method thereof which are beneficial to rapid and automatic production. Background technique [0002] Existing three-dimensional mask, it comprises mask body, is located at its two sides and is used for hanging on the user's ear elastic band; Its shortcoming is: during production, need manual symmetrical bending of two elastic bands and transfer to mask body and align them, and then fix the elastic bands on both sides of the mask respectively. This production process takes a long time and requires manual operation, which is time-consuming and labor-intensive, which is not conducive to continuous and rapid production. How to provide a mask that reduces the time-consuming production is a technical problem to be solved in this area. Contents of the invention [0003] The technical problem to be solved by the present i...
