Description

Preparation process of reinforced attaching type mask

Technical Field

The invention relates to the field of masks, in particular to a preparation process of a reinforced attaching type mask.

Background

At present, the Chinese patent number: CN201420606372.4 discloses a folding mask, which comprises a mask body and ear buttons, wherein the mask body comprises two layers of polypropylene non-woven fabrics, a layer of melt-blown non-woven fabric and a layer of common non-woven fabric; two-layer polypropylene fibre non-woven fabrics are located the outmost and the inlayer of gauze mask body respectively, melt blown non-woven fabrics and ordinary non-woven fabrics are located respectively between two-layer polypropylene fibre non-woven fabrics, and the polypropylene fibre non-woven fabrics contact of ordinary non-woven fabrics and inlayer. The folding mask has good filtering effect, can achieve the filtering effect of 0.3 micron dust particles of over 99 percent, and can shield liquid, bacteria, viruses and the like. Which discloses the general structure of existing folding masks.

However, the existing folding masks are usually formed by sewing two single pieces, a closed end is formed at one sewn end, and an open end is formed at the other end which is not sewn, and the sewing mode is usually formed by using a hot pressing mode, namely, a hard hot pressing mark is formed by damaging materials, and if the hot pressing mark can be effectively reduced, the breathing smoothness of the masks can be improved. Moreover, the disposable mask is often only in the specifications of adults and children, is difficult to match the face shape of all people, is easy to cause the reduction of the sealing performance of the mask, and is easy to cause the sliding of the mask, thereby influencing the use performance of the mask.

Disclosure of Invention

Therefore, aiming at the problems, the invention provides a preparation process of a reinforced attaching type mask, which provides a process capable of producing a reinforced attaching type mask which has better air permeability and is not easy to slide off, and solves the technical problem that the air permeability of the existing folding type mask is influenced by forming a sewing part at the nose bridge part through hot pressing.

In order to achieve the purpose, the invention adopts the following technical scheme: a preparation process of a reinforced attaching type mask comprises the following steps:

firstly, unwinding a nose bridge strip, cutting, inputting after cutting, and adhering the nose bridge strip on a strip-shaped non-woven fabric at intervals;

step two, unwinding the outer layer non-woven fabric, the melt-blown non-woven fabric and the inner layer non-woven fabric respectively, and inputting the two in a mutually overlapped mode, wherein when the input is carried out, the strip-shaped non-woven fabric is clamped between the outer layer non-woven fabric and the melt-blown non-woven fabric, so that the mask base material is formed;

thirdly, carrying out hot pressing on the mask base material to form the appearance of the basic mask body, wherein the basic mask body comprises two sheet bodies, each sheet body comprises a folding part, an opening end, a chin area and a mouth area which are sequentially connected, a nose area is formed between the folding part and the mouth area of each sheet body, and the two sheet bodies are integrally connected in the nose area;

fourthly, carrying out secondary hot pressing on the mask base material, forming a limit hot indentation on the peripheral side of the nose bridge strip, and forming two first support hot indentations and one second support hot indentation on the mask base material;

fifthly, indentation is carried out on the middle part of the mask base material to facilitate subsequent folding;

sixthly, unwinding, cutting, adsorbing and conveying the ear belt materials, finally compounding the ear belt materials on the mask base material in an adhesive mode, carrying out hot-pressing adhesion on the parts, close to the opening ends, of the ear belts, and connecting the ends, close to each other, of the two ear belts through a tearing line;

seventhly, cutting the mask base material to form a single mask body, turning the mask body by 90 degrees, and folding the mask body along the nose area;

eighthly, carrying out hot pressing on a folded part, a chin area and a mouth area of the folded mask, forming a closed end by matching with the nose area, and cutting;

and ninthly, outputting.

Furthermore, one first supporting hot impression extends from one side of the nose area to the middle of the opening end, the first supporting hot impression is close to the mouth area, the other first supporting hot impression extends from one side of the mouth area to the middle of the opening end, the first supporting hot impression is close to the chin area, more than one second supporting hot impression is arranged on each sheet body, and the second supporting hot impressions extend from the folding portions to the middle of the opening end.

Furthermore, each first supporting thermal impression and each second supporting thermal impression are not parallel to each other, the second supporting thermal impression has an intersection with the adjacent first supporting thermal impression, and the second supporting thermal impression does not have an intersection with another first supporting thermal impression.

By adopting the technical scheme, the invention has the beneficial effects that: the production process of the folding mask can effectively realize the effective input and clamping of the nose bridge strip through the input and the interval adhesion of the nose bridge strip, greatly improve the stability and effectively realize the accurate layout. Through the respective arrangement of the primary hot pressing and the secondary hot pressing, the effective forming of the hot pressing can be effectively realized. Carry out the indentation to the middle part of gauze mask body appearance, this indentation can make things convenient for in subsequent folding, especially can effectively improve to the folding stability of nose bridge strip. Because the ear straps on the two sheets are actually integrally formed, high-speed compounding of the ear straps is facilitated. The technology can realize the on-line quick compounding and accurate compounding of the nose bridge strip, so that the folding mask can realize high-efficiency production, and the mode that the nose bridge strip of the existing folding mask needs to be secondarily applied after the mask body is formed is changed, and the efficiency is lower. The problem that the production efficiency of the existing folding mask is low is also solved, the existing folding mask usually has a speed of less than 300 pieces/minute, the scheme can realize online one-step forming, the speed can reach 500 pieces/minute and 600 pieces/minute, and when the precision of the equipment is improved and the precision instruments such as an encoder and a high-speed camera are used for adjustment, the efficiency can be improved again. The strengthened attaching type mask produced by the process realizes better air permeability, better supporting performance and better sealing performance. And in this way, when the nose part area is folded during forming, less material can be cut off, thereby being beneficial to saving materials. The lamellar body passes through the range upon range of setting of outer non-woven fabrics, melt-blown non-woven fabrics inlayer non-woven fabrics, can effectively realize its filter effect's improvement. The setting of book portion has formed a position that is used for the lock bridge of the nose, and this position can effectively improve sealing performance, can effectively reduce the gliding of gauze mask, and the contained angle that book portion and nose region are greater than 2 degrees and be less than 15 degrees, can effectively realize the realization of this function. The forming of the three-dimensional shape of the sheet body can be effectively realized by the aid of the first supporting hot indentations, the supporting of the folded part region can be effectively realized by the aid of the second supporting hot indentations, and nose bridges and the face are tightly attached to the upper edge of the opening end of the mask. And the distance from the intersection point of the folding part and the nose part area to the nose bridge strip is more than 3mm and less than 6mm, so that the hot-pressed part can be effectively reserved, and the effective fixation is realized.
