Processing process of ear band edge covering mask

Abstract

The invention relates to the field of mask production and particularly relates to a process for processing a mask with edges wrapped by ear bands. The process comprises the following steps of preparing a sheet body, clamping melt-blown cloth between two layers of non-woven fabrics, and performing sheet making to form a single mask sheet body; lug belt welding, symmetrically welding lug belts at two ends of the sheet body in the length direction by using a lug belt welding part in a lug belt outer covering edge welding system; folding an ear belt, folding the ear belt to a surface body of the sheet body by using an ear folding part in the ear belt outer covering edge welding system; correcting the ear belt, correcting the part, positioned on one side of the sheet body advancing direction, of the ear belt by using an ear belt correcting part in the ear belt outer wrapping edge welding system; edge covering on the side edges, ear bands being welded, of the sheet bodies through edge covering parts in the ear band edge covering welding system. The process has effects of improving mask production efficiency and improving the mask quality.

Description

technical field [0001] The present application relates to the field of mask processing and production, in particular to a processing technique for earband-wrapped mask. Background technique [0002] Common masks on the market are generally divided into two categories, one is that the ear straps are outside the mask edge, that is, the ear strap inner edge, and the other is that the ear strap is on the inside of the mask edge, that is, the ear strap outer edge, and the ear strap outer edge mask Compared with the mask with inner ear straps, the ear straps are more tightly connected to the mask cloth, and the service life is relatively longer. [0003] Aiming at the production method of the earband wrapping mask involved in the related art, the inventor believes that there are the following defects: in the process of wrapping the earband after welding, the earband needs to be folded on the sheet body, and in order to ensure that the produced mask In order to ensure the quality ...
