Mask machine production line

Abstract

The invention relates to the field of mask production equipment, particularly to a mask production line which can produce masks applicable to most people and well fitting with the face of a user whenbeing worn and is high in production efficiency. The mask production line comprises a rack, a control device arranged on the rack, an unwinding device, a pre-pressing edge-cutting device, a cushion forming device, a turnover device, an ear belt discharging and spot welding device, a folding device, an inclined sealing device, a slitting device, a nose bridge strip discharging and slitting device and a nose bridge strip welding and discharging device, wherein the cushion forming device comprises an edge sealing mechanism used for sealing the edge of a cover body and bending and warping cushionparts, and further comprises a welding mechanism used for enabling the cushion part to be distributed in a stacked mode and connecting the free edges of the cushion parts with the cover body.

Description

technical field [0001] The invention relates to the field of mask production equipment, in particular to a mask machine production line. Background technique [0002] A mask is a kind of sanitary product, which generally means that it has a certain filtering effect on the air entering the lungs when worn on the mouth and nose. When working in an environment polluted by respiratory infectious diseases or dust, wearing a mask has a good effect. Made of gauze or paper, it includes industrial masks, civil masks and medical masks according to different application fields. Among them, the technical requirements for medical protective masks stipulate that according to the national standard GB19083-2010 of the People's Republic of China, the basic requirements are: the mask should cover the wearer's mouth and nose, and should have good face tightness, and the surface should not have holes, Stains, there should be no exhalation valve, suitable for self-priming filter medical protect...

AI Technical Summary

Problems solved by technology

And fixed at the gas flow rate of 85L / min, the filter efficiency of the mask for non-oily particles is not less than 95%

[0003] Most of the existing masks sold on the market can meet the requirement that the filtration efficiency of non-oily particles is not less than 95% in the test. However, the specifications and sizes of masks are only divided into adult masks and children's masks, and the test results The test instruments are all prepared and tested in accordance with the standard conditions. In actual consumer use, the face shapes and sizes of different users are different, making the effectiveness of the mask different for each user.

[0004] In addition, the mask mainly includes a cover body made of melt-blown cloth and spunbond cloth, and ear straps connected to the cover body for easy wearing by the user. The edges of the mask body are sealed by ultrasonic or heat pressing. The softness is poor, so that the fit with the user's face is poor when worn, resulting in poor air tightness
