Description

Mask and manufacturing process and device

Technical Field

The invention belongs to the field of sanitary product device manufacturing, and particularly relates to a mask and a manufacturing process and device.

Background

At the end of the 19 th century, masks began to be used in the medical care field, in 1918, "Spanish flu", and people were forced to wear masks to protect against flu, which was the beginning of widespread use of masks. Since then, not only medical science has been rapidly developed, but also masks have become indispensable medical instruments and health tools, and have been widely used. In 1897, German America introduced a method of wrapping the nose and mouth with gauze to prevent bacterial invasion. Later, a mask with six layers of gauze was made and sewn on the collar. When in use, the mask is turned over to cover the mouth and the nose. However, the mask is always pressed by hand, which is very inconvenient. Later, people thought to tie the mask on the ears by using a belt, so that the mask is frequently used by people today.

The mask must be of a proper size and must be worn correctly, and the mask protection function is effective. Commercially available masks generally fall into two categories, rectangular and cup-shaped. The rectangular mask has a protective function only by adopting a structure with at least three layers of paper. The user can press the iron wire on the mask on the nose bridge and then spread the whole mask along the nose bridge to exert the efficacy. The cup-shaped mask is effective only when the density of the mask is enough after the mask is attached to the face and the exhaled air does not leak.

The length of the ear belt is fixed, and the distance between the two ears of the head is different because the head sizes of each person are different. This is often the case with the same ear strap type mask, which is too tight for some people and too loose for some people. When the mask is worn, the density of the mask is enough after the mask is attached to the face, the exhaled air cannot leak, and the mask has a protection effect; when the mask is worn loosely, the density of the mask is insufficient after the mask is attached to the face, air can leak out after the mask is exhaled, and the mask does not have a protection effect.

There is also a case where: medical care personnel in hospitals need to wear protective clothing first when working. After the protective clothing is worn by the medical personnel, the ear-band type mask cannot be conveniently worn on the two ears of the medical personnel because the protective clothing wraps the head of the medical personnel, and the bandage type mask can be conveniently tied on the back part of the brain of the medical personnel.

Compared with an ear strap type mask, the bandage type mask has the advantages that: the wearer can conveniently adjust the tightness of the bandage by himself, the back density of the mask on the face can be guaranteed to be sufficient, the exhaled air cannot leak, and the mask has a protection effect. Meanwhile, the tightness of the binding band can be conveniently adjusted by the wearer, and the wearing comfort of the wearer is also kept.

Compared with an ear strap type mask, the bandage type mask has the following advantages when in use: under the condition that the mask cannot be worn by the wearer, the bandage type mask can be conveniently worn by other people. This is often the case, for example: when the medical staff has instruments in the hands, the upper limbs or the disabled hands, and the like.

While bandaging masks have found numerous applications in manufacturing and in life, bandaging masks have undeniably had their particular drawbacks. Especially, in the process of manufacturing the bandage type mask, the overlong bandage of the bandage type mask is often wound on the mask machine due to the overlong bandage of the bandage type mask. Therefore, the bandage type mask cannot be automatically manufactured on a mask machine, and the bandage needs to be welded or sewn on the mask body manually, so that a large amount of manpower is wasted, and the production efficiency of the bandage type mask is reduced. Meanwhile, the bandage is welded or sewn on the mask body by hands, so that the bacterium content of the mask is increased, and the potential safety hazard is increased when the mask is worn.

Detailed Description

In order that the invention may be more fully and clearly understood, reference will now be made to the following description and accompanying drawings, which are included to provide a further understanding of the invention.

Example 1

The embodiment provides a bandage type mask, which comprises a mask body and a bandage strip, wherein the bandage strip is formed by compounding elastic cloth and spunlace cloth.

The mask body can be prepared according to the prior art, and the embodiment also provides a specific manufacturing method. The manufacturing steps of the binding strip are as follows: compounding the elastic cloth and the spunlace cloth to obtain a flat mask fixing band; the flat binding bands are overlapped to form a laminated mask fixing band; the laminated mask fixing belt penetrates through the heating point connecting needle of the point connecting mechanism, and then the belt is cut into the mask fixing belt strips.

The device and process for manufacturing the bandage type mask and the bandage structure are shown in fig. 1-12. The specific description is as follows.

As shown in FIG. 1: the melt-blown non-woven fabric (1) and the inner non-woven fabric (2) are compounded into a plane by the excircle of the lower guide wheel (21), and the nose strips (3) are uniformly arranged on the compounded melt-blown non-woven fabric (1) and the inner non-woven fabric (2) by the nose strip wheel (22). The outer non-woven fabric (4) is covered on the melt-blown non-woven fabric (1) and the inner non-woven fabric (2) by an outer non-woven fabric guide wheel (23) to form the nose strip mask body (5). The nose strip mask body (5) is manufactured into a three-fold mask body (6) after passing through a three-fold upper wheel (24) and a three-fold lower wheel (25) of a three-fold device. The three-folded cover body (6) passes through a peripheral seal upper wheel (26) and a peripheral seal lower wheel (27) of a peripheral seal device to form a peripheral seal cover body (7).

The elastic cloth (9) and the spunlace cloth (8) are compounded into a flat binding band (10) by an upper guide wheel (31), and the flat binding band (10) is flattened into an initial-folding binding band (11) by a front pressing upper wheel (32) and a front pressing lower wheel (33). The primary folding binding belt (11) is manufactured into a folding binding belt (12) by a folding device consisting of a left lower folding plate (34), a right lower folding plate (35), a left upper folding plate (36) and a right upper folding plate (37). The laminated binding belt (12) is flattened into a flattening binding belt (13) by a rear pressing upper wheel (38) and a rear pressing lower wheel (39). The flattening bandage (13) is made by penetrating point connecting needles on a point connecting mechanism consisting of a point connecting upper wheel (41) and a point connecting lower wheel (42) into point connecting bandage (14), and because the point connecting needles are provided with heating devices, materials around the penetrated holes are slightly melted, and the overlapped point connecting bandage (14) can not be scattered. The point-connecting binding belt (14) is conveyed to a slitting device consisting of a binding belt upper cutting wheel (44) and a binding belt lower cutting wheel (45) by a binding belt conveying device (43), the point-connecting binding belt (14) is a binding belt strip (15), and the binding belt strip (15) is welded on the peripheral sealing cover body (7) through ultrasonic welding (47). Finally, the peripheral sealing cover body (7) welded with the binding band strips (15) is cut into a single binding band mask (16) uniformly by an upper mask cutting (48) and a lower mask cutting (49), and then the binding band mask is conveyed out by a product conveyor (50) to finish the manufacture of the binding band mask.

The bandage is made of elastic cloth and spunlace cloth, and the invention also discloses an ear belt mask made of only one non-woven fabric (figure 13). The process and equipment are the same as those of the bandage type mask. The two ends of the ear strap (17) are welded on the mask body, and after the ear strap (17) is folded, the point-connecting needle hole (14.1) can not lead the ear strap (17) to scatter in the mask manufacturing process.

The invention discloses a device for uniformly placing nose strips (3): referring to the schematic view of the nasal strip applicator of the present invention (fig. 2), the trimmed nasal strips (3) are arranged in a nasal strip row (22.1) in sequence. When any one empty nasal strip groove (22.2) of the rotating nasal strip wheel (22) is aligned with the outlet of the nasal strip discharge pipe (22.1), the nasal strips (3) in the nasal strip discharge pipe (22.1) fall into the nasal strip groove (22.2). The nose strip wheel (22) continues to rotate, the cambered surface (22.3) seals the outlet of the nose strip discharge pipe (22.1), and the nose strip (3) cannot continuously fall. The nose strip wheel (22) continues to rotate, and after the next empty nose strip groove (22.2) is aligned with the nose strip discharge pipe (22.1), the nose strip (3) continues to fall into the nose strip groove (22.2). An eagle hook (22.4) is designed in the nose strip groove (22.2), the eagle hook (22.4) is similar to an eagle pecking, when the nose strip wheel (22) rotates, the eagle hook (22.4) hooks the nose strip (3) in the nose strip groove (22.2), and the nose strip (3) cannot be separated from the nose strip groove (22.2). The nose strip wheel (22) continues to rotate, when the nose strip groove (22.2) is vertical to the melt-blown non-woven fabric (1) and the inner non-woven fabric (2), the nose strip (3) leaves the eagle hook (22.4) and falls on the melt-blown non-woven fabric (1) and the inner non-woven fabric (2), and the process of uniformly placing the nose strip (3) is completed.

It should be noted here that when the rotation direction of the nose strip wheel (22) is the same as the advancing direction of the melt-blown non-woven fabric (1) and the inner non-woven fabric (2), the nose strip (3) is accurately positioned on the melt-blown non-woven fabric (1) and the inner non-woven fabric (2) because the advancing direction is the same; when the rotation direction of the nose strip wheel (22) is opposite to the advancing direction of the melt-blown non-woven fabric (1) and the inner non-woven fabric (2), the nose strip (3) has larger positioning error between the melt-blown non-woven fabric (1) and the inner non-woven fabric (2) because the advancing directions are different.

After the nose strips (3) are uniformly placed, the outer non-woven fabric (4) is guided by an outer non-woven fabric guide wheel (23) to cover the nose strips (3), the melt-blown non-woven fabric (1) and the inner non-woven fabric (2). At this time, the outer nonwoven fabric (4), the nose strip (3), the melt-blown nonwoven fabric (1), and the inner nonwoven fabric (2) form a nose strip mask body (5). The nose strip mask body (5) continues to move linearly and becomes a three-fold mask body after passing through a three-folding device.

The invention relates to a three-folding device: referring to the schematic view of the tri-folding apparatus of the present invention (fig. 3), the upper tri-folding wheel (24) and the lower tri-folding wheel (25) are on a vertical axis and form a step. Correspondingly: the upper wheel small circle (24.1) and the lower wheel large circle (25.1) are on the same vertical plane; the upper wheel inclined plane (24.2) and the lower wheel inclined plane (25.2) are on the same vertical plane; the upper wheel big circle (24.3) and the lower wheel small circle (25.3) are on the same vertical plane. The device has 3 corresponding steps.

The three-folding upper wheel (24) and the three-folding lower wheel (25) rotate oppositely, when the nose strip mask body (5) passes through a gap between the three-folding upper wheel (24) and the three-folding lower wheel (25), the nose strip mask body (5) is extruded by the upper wheel inclined plane (24.2) and the lower wheel inclined plane (25.2), and then the straight nose strip mask body (5) is deformed and folded. The 3 corresponding steps enable the straight nose strip mask body (5) to form 3 deformation folds, and the three folds of the mask are completed.

The three-folding mask body continues to move linearly and becomes a peripheral sealing mask body after passing through a peripheral sealing device.

The invention peripheral device: referring to the schematic view of the present invention (fig. 4), the upper wheel (26) and the lower wheel (27) rotate relative to each other. The outer circle surface of the peripheral seal upper wheel (26) is a peripheral seal lattice (26.1), and the middle part of the peripheral seal lattice (26.1) is a concave peripheral seal groove (26.2). When the three-folding mask body penetrates through a gap between the peripheral seal upper wheel (26) and the peripheral seal lower wheel (27), the three-folding mask body is subjected to extrusion force of the peripheral seal upper wheel (26) and the peripheral seal lower wheel (27), and three layers of materials of the three-folding mask body are pressed into a whole, namely, the periphery of the three-folding mask body is sealed into neatly arranged grids, so that the sealing of the mask body is completed.

A peripheral sealing heating device can be added: referring to the schematic drawing of the tri-folding apparatus of the present invention (fig. 4), the upper peripheral seal wheel (26) is equipped with an upper peripheral seal heating element (26.3), and the lower peripheral seal wheel (27) is equipped with a lower peripheral seal heating element (27.1). The heating elements (26.3) of the upper peripheral sealing wheel and the heating elements (27.1) of the lower peripheral sealing wheel adopt electric heating rods, and the heating temperature is 170 ℃.

The spunlace fabric (8) and the elastic fabric (9) are compounded into a flat binding band (10) by the excircle of an upper guide wheel (31), and the flat binding band is laminated into a laminated binding band (12) by a laminated plate device. The front upper pressing wheel (32) and the front lower pressing wheel (33) are a pair of opposite steering wheels with smooth outer circular surfaces and are used for flattening the bandage (10).

The invention discloses a laminated superposed plate device: reference is made to a schematic illustration of a lamination stack apparatus of the present invention (fig. 5), a schematic illustration of a cross-section of a lamination stack apparatus and a lamination band of the present invention (fig. 6), and a schematic illustration of a cross-section of a lamination band of the present invention (fig. 7).

The left lower folding guide edge (34.1) of the left lower folded plate (34) enables the flat binding band (10) to be gradually folded in the advancing process by means of the bent radian; by parity of reasoning, the right lower folded edge (35.1) of the right lower folded plate (35) enables the flat binding band (10) to be gradually folded in the advancing process by means of the bent radian; the left upper folded edge (36.1) of the left upper folded plate (36) enables the flat binding band (10) to be gradually folded in the advancing process by means of the bent radian; the right upper folding edge (37.1) of the right upper folding plate (37) enables the flat binding band (10) to be gradually folded in the advancing process by means of the bent radian.

The rear upper pressing wheel (38) and the rear lower pressing wheel (39) are a pair of opposite-turning pairs with smooth outer circular surfaces and are used for flattening the laminated binding band (12), and the flattened binding band (13) is formed after the laminated binding band (12) is flattened.

Of particular note are: the right end (8.1) of the spunlace fabric is not aligned with the right end of the elastic fabric (9) but extends out of the right end; the left end (9.1) of the elastic cloth is not aligned with the left end of the spunlace cloth (8) and extends out of a part with the length approximately equal to the width of the peripheral seal.

The whole flattening binding belt (13) is penetrated by the point connecting upper wheel (41) and then is a point connecting binding belt (14), and the overlapped laminated binding belt cannot scatter.

The invention discloses a point connecting device: referring to the schematic view of the point connecting device (fig. 8) and the schematic view of the point connecting band (fig. 9): the point connecting needles (41.1) evenly distributed on the outer surface of the point connecting upper wheel (41) penetrate through the laminated binding belt (12). The heating rod (41.2) is connected with the upper wheel (41) for heating, and the heating temperature is 170 ℃.

The shape of the point connecting needle (41.1) is a cone, and the height of the cone is required to be set according to the thickness of the laminated binding band. The ratio of the height of the cone to the thickness of the laminated binding band is 1.2: 1. the height of the cone is too low, and the point connecting needle (41.1) can not penetrate through the laminated binding band; the height of the cone is too high, and the point connecting needle (41.1) is easy to break.

The point connecting binding bands (14) are cut into binding band strips (15) in a cutting device. The width of the binding tape (15) is 30mm, then the cutting device is required to be divided into 2 in the middle 1, the width of each side is 15mm, the length depends on the number of superposed layers, 3 layers can be superposed in the embodiment, 2 layers can also be superposed after 4 layers, and the superposed length can be slightly changed. Too wide wastes material and too narrow of the strap (15) tends to snap.
