Description

Technical Field

[0001] The invention relates to mask production equipment, and in particular to a mask folding device and mask production equipment. Background Art

[0002] During the production process of masks, the side edge sealing of the mask fabric, the addition of the nose bridge strip, the fabric folding, the transverse edge sealing and cutting of the fabric are required to form the mask body, and then the ear straps are welded to the two sides of the mask body through welding equipment to finally form the finished mask. During the fabric folding process, the continuous fabric is generally guided and conveyed through multiple sets of folding plates. After being guided by the folding plates, a multi-layer folded shape is initially formed, and then the folding position is re-shaped by the pressing plate to finally form a multi-layer folded shape. This traditional folding device has a poor folding effect on the fabric, and after being guided by the folding plate, the pressing plate needs to be fixed again to form a folded shape. Both production efficiency and production quality need to be improved. Summary of the invention
