Mask machine

Abstract

The invention provides a mask machine which comprises an ear belt line conveying device, a folding and wrinkling pressing device and a rack; the ear belt line conveying device and the folding and wrinkling pressing device are arranged up and down in the vertical direction, and the folding and wrinkling pressing device is arranged above the ear belt line conveying device. An ear belt line penetrating through the ear belt line conveying device is arranged in the middle of the mask layer material in the middle of the folding, wrinkling and pressing device, and the ear belt line conveying device does telescopic motion between the mask layer materials; the lengths of the ear belt lines can be flexibly adjusted, and the lengths of the two ear belt lines of the mask can be different, so the ear belt lines of the mask can fully meet personalized requirements and use requirements, and the ear belt lines of the mask are prevented from being broken due to insufficient length; by improving the structure of the folding wrinkle pressing device, the two-piece type structure of the duckbilled mask is changed into the one-piece type structure, and wrinkles in the middle of the duckbilled mask are increased.

Description

technical field [0001] The invention relates to mask production equipment, in particular to a mask machine. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, viruses, and droplets from entering and exiting the wearer's mouth and nose. The mask is mainly made of non-woven fabrics Made of gauze, the mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0003] Existing masks are generally produced automatically by mask production equipment. The mask production equipment manufactures a filter with a certain filtration performance through processes such as hot pressing, folding, ultrasonic welding, waste removal, and welding of ear loops and nose bridge strips. Various masks, ...

Problems solved by technology

After the segmental interception material tape produces masks one by one, the length of the ear strap line in each mask is exactly the opening width of the mask, therefore, the above-mentioned equipment cannot produce a mask whose ear strap line length is greater than the mouth mask opening width Control the length of the ear loops so that the ear loops of the mask often break due to insufficient length

The duckbill-shaped mask is composed of multi-layer materials welded and pressed together, but the internal breathing space of this mask is relatively small. When worn for a long time, it is easy to cause hypoxia. In addition, the multi-layer materials are welded and pressed together. The border is easy to crack, causing damage to the mask
