Description

The arrangement structure of the face sheet two-fold direction change roller {The arrangement structure of the face sheet two-fold direction change roller}

The present invention relates to a method and device for printing character patterns on the surface of a mask by changing the direction of a surface sheet in manufacturing a mask, which has become commonplace due to a global panic caused by Corona 19.

Have you ever seen someone wearing a mask in the past? I looked at it with the thought of doing it, but as the 2020 corona spread in earnest, it became a situation where I was wary of people who did not wear a mask.

In the meantime, everyone has expanded their expertise in masks used in daily life, and in the meantime, in Korea, quasi-drug health masks and KF-89, KF-94, and KF-99 health masks are classified into highly effective KF-94 grade masks. use is recommended.

On the other hand, the quasi-drug health mask refers to a mask used when necessary in daily life for the purpose of protecting the respiratory tract from particulate harmful substances or infectious agents because it has particle blocking performance, and the latter KF-89, 94, 99 for health As for the mask, KF is an abbreviation of Korea Filter, and the number after it refers to the rate of blocking particles such as fine dust. 89 indicates 89% particle blocking performance and 99 indicates 99% blocking performance There is a difference that the higher you go, the more difficult it is to breathe due to its denseness.

KF-80 blocks more than 80% of fine particles (average particle size 0.6㎛) to protect the respiratory system from particulate harmful substances such as yellow dust and fine dust. 0.4㎛), respectively, blocking more than 94% and 99%, respectively, it can be known from the government's announcement that it can protect the respiratory system from harmful particulate substances such as yellow dust or fine dust and infectious agents such as swine flu.

Therefore, for health masks, only products with particle blocking performance are recognized as quasi-drug “health masks,” so the way to check health masks approved as quasi-drugs is to print the letters “quasi-drugs” and “KF-80, KF-94” on the product packaging. , KF-99" mark.

As for the method of selecting a mask, it is desirable to select a product in consideration of the level of yellow dust or fine dust and individual respiratory rate, rather than choosing only a product with a high blocking rate. For reference, the government's health mask management standards are shown in the table below. .

Dust collection efficiency
(fine dust blocking rate) Face leak rate
(Rate of air leakage) Blocks 80% of average particle size of 06.㎛ 25% or less Blocks 94% of average particle size of 04.㎛ 11% or less Blocks 99% of average particle size of 04.㎛ 5% or less

In addition, the types of health masks include 'folding' products that are folded up and down or left and right as general disposable products, 'cup-type' products that have the shape of a convex cup, and disposable filters attached to the mask body. There is a filter replacement type that can be reused by replacing only the filter, and an exhaust valve type product that reduces the discomfort of exhalation (exhalation) when worn by allowing air to be discharged through the exhaust valve in the main body of the mask, and exhaust There is a filter replacement and exhaust valve type product that is used by attaching a replaceable disposable filter to the mask body with a valve.

On the other hand, masks recognized by the government are given KF-89, KF-94, and KF-99 marks, and the manufacturer performs color printing on the packaging paper and the outer surface of the mask at least one degree.

By the way, the method of printing on the wrapping paper is the same as the general printing method, so there is no difficulty in printing during the manufacturing process of the wrapping paper. The job is to do the print job.

Therefore, it goes without saying that the manufacturing cost increases due to the working process, but it is true that there is a significant loss in profits due to contamination of the mask and inaccurate printing defects due to the environment in which printing is performed after manufacturing.

Therefore, the present invention solves the conventional problem and provides a good quality mask to be supplied in a timely manner at a low cost. It is possible to automatically print a character pattern by changing the direction of a surface sheet in the process of manufacturing a mask.
