Description

Technical Field

[0001] The invention relates to a mask manufacturing device, in particular to an outer ear-to-inner earphone of a mask. Background Art

[0002] The two U-shaped ear straps of the masks produced by the existing mask machines are both outside the two sides of the mask piece, which are called outer ear masks in the mask industry. The outer ear masks are very inconvenient to package. Since the ear strap mechanism of the existing mask machine generally uses a rotating turntable to wind the ear straps into a U shape, and then weld the ear straps to the mask piece, such an upper ear strap mechanism can only provide outer ears for the mask piece. Therefore, the two ear straps of the finished outer ear mask need to be manually folded into the mask piece, and then flattened for packaging, which leads to low work efficiency and increased production costs. Summary of the invention
