Three-dimensional mask with large mouth space and production method thereof

Abstract

The invention provides a three-dimensional mask with a large mouth space and a production method thereof.The mask comprises a pair of mask fabric layers, the mask fabric layers are trapezoidal and are vertically symmetrical, the upper bottom edges of the mask fabric layers are connected in a sealed mode, the adjacent waist edges of the mask fabric layers are connected in a sealed mode, and the lower bottom edges of the mask fabric layers are open; and the two sides of the lower bottom edge of at least one mask fabric layer are connected with elastic belts. The production method of the three-dimensional mask comprises the following steps: the two long-strip-shaped mask fabric layers are laid in the length direction in an up-down laminated mode; ultrasonic welding is conducted on the two long-strip-shaped mask fabric layers, trapezoid bodies arranged in sequence are obtained, and only the upper bottom edge and the two waist edges of each trapezoid body are subjected to ultrasonic welding; the elastic belts are connected to the two sides of the lower bottom edge of each trapezoid body; and cutting is performed along the waist edge of each trapezoid body to obtain a plurality of mask finished products.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary consumables, in particular to a three-dimensional mask and a production method thereof. 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. Simultaneously, mouth space is less, and use comfort is lower; How to provide a kind of mouth mask that reduces production time consumption, is the technical problem to be solved in this field. Contents of the invention [0003] The technical problem to ...
