Description

Manga for insect screen and manufacturing method thereof {Insect screen by using perforated sheet paper}

The present invention relates to building equipment and facilities. More specifically, it relates to a mesh for insect screens for preventing the inflow of pests or foreign substances and a method for manufacturing the same.

An insect screen (screen, insect screen, mosquito net, fly net) is a net installed in an opening for air circulation, such as a window or door, in order to block the inflow of pests or foreign substances.

In the conventional insect screen, a mesh of a fine size is manufactured by weaving metal yarns or synthetic fibers into a grid, and the manufactured mesh is attached to the opening and installed. Here, the metal yarn may be a stainless steel yarn, an aluminum yarn, or the like, and the synthetic fiber may be a nylon yarn, a polyester yarn, a polyethylene yarn, or the like.

However, in the case of the conventional mesh fabric woven with metal yarn, it is difficult to construct because the metal yarn has no flexibility, and the size of the hole is relatively large, so there is a limitation that it cannot completely block pests of a relatively small size. And, in the case of the conventional mesh fabric woven with synthetic fibers, there is a limitation in that the holes of the mesh are easily clogged because dust and the like are easily attached to the synthetic fiber mesh.

In the case of a conventional mesh woven with metal or synthetic fibers, at least one of weft (weft, warp) or warp (warp) is pushed by an external force, and the size of the mesh hole can be easily deformed. As such, when the mesh hole is expanded by pushing the weft or warp yarn, pests or foreign substances may be introduced through the expanded mesh hole.

In addition, in the case of the conventional net paper, when the holes of the net are small to effectively block the inflow of pests or foreign substances, the permeability is greatly deteriorated by the weft yarn and warp such as metal yarn or synthetic fiber, and the flow rate of air is greatly reduced. do.

Therefore, there is a need for a mosquito net using a mesh of a different structure, rather than using a mesh woven with weft and yarn.

As described above, the conventional insect screen was manufactured using a mesh in which metal yarns or synthetic fibers were woven into a grid. However, in the case of mangji made of metal thread, it is difficult to construct because the metal thread has no flexibility, and the size of the hole is relatively large, so there is a limit in that it cannot completely block pests of a relatively small size. In the case of a mesh made of synthetic fibers, there is a limitation in that the holes of the mesh are easily clogged because dust and the like are easily attached to the synthetic fiber mesh. In addition, in the case of a mesh woven with metal yarn or synthetic fiber, there is a limit that at least one of the weft yarn or the warp yarn is pushed by an external force, and the size of the mesh hole is easily deformed.

In order to overcome this limitation, the present invention intends to propose a mosquito net using perforated sheet paper. In particular, various wing structures may be formed in the mesh of the insect screen to be proposed by the present invention.

The second sheet 212 may be stacked on the first sheet 211 so that the central axis of the second micropore O2 and the central axis of the first micropore O1 do not coincide. For example, the second sheet paper 212 may be stacked to be shifted from the first sheet paper 211 . Accordingly, only a portion of each of the second micropores O2 may overlap a portion of the first micropore O1 adjacent in the third direction d.

In an embodiment, a portion of the second micropore O2 may overlap a portion of the first micropore O1 adjacent in the third direction d in the third direction d. A portion of the second micropore O2 overlapping a portion of the first micropore O1 may be referred to as a first overlapping region SP1 (refer to FIG. 9B ). In other words, each of the second micropores O2 may include a first overlapping region SP1 overlapping a portion of each of the first micropores O1 . Accordingly, air may pass through the first sheet paper 211 and the second sheet paper 212 through the first overlapping area SP1 . As described above, the first overlapping region SP1 is a region where a part of the first micropore O1 and a part of the second micropore O2 overlap, so the width SW1 of the first overlapping area, see FIG. 9B . ) may be smaller than the first width W1 and the second width W2. For example, the width SW1 of the first overlapping region may be 1/2 times smaller than the first width W1 . Accordingly, the size of the first overlapping area SP1 may be 1/4 times smaller than that of the first micropore O1 .

The third sheet 213 may be laminated on one surface of the second sheet 212 . The third sheet 213 may be laminated on the second sheet 212 and attached to one surface of the second sheet 212 by an adhesive.

The third sheet 213 may include a plurality of third fine holes O3 passing therethrough. Each of the third micropores O3 may be spaced apart from each other. In an embodiment, the third micropores O3 may be arranged in a grid pattern.

Each of the third micropores O3 may correspond to each of the second micropores O2 adjacent in the third direction d. In an embodiment, the second width W2 of each of the second micropores O2 may be substantially the same as the third width W3 of each of the third micropores O3 . Accordingly, in an embodiment, the first width W1 , the second width W2 , and the third width W3 may be equal to each other. The third sheet of paper 213 is such that the central axis of the second micropore O2 and the central axis of the third micropore O3 do not coincide, for example, the third sheet 213 is the second sheet 212 and They may be stacked to be shifted. It may be laminated on the second sheet paper 212 . Accordingly, a portion of each of the third micropores O3 may overlap a portion of the first overlapping region SP1 adjacent in the third direction d.

A portion of each of the third micropores O3 may overlap a portion of the first overlapping region SP1 in the third direction d. A portion of the third micropore O3 overlapping a portion of the first overlapping area SP1 may be referred to as a second overlapping area SP2 (refer to FIG. 10B ). In other words, each of the third micropores O3 may include a second overlapping area SP2 overlapping a portion of the first overlapping area SP1 . Accordingly, air may pass through the first sheet paper 211 , the second sheet paper 212 , and the third sheet paper 213 through the second overlapping area SP2 . Since the second overlapping area SP2 overlaps a portion of the first overlapping area SP1 , the width SW2 of the second overlapping area may be smaller than the width SW1 of the first overlapping area.

The fourth sheet 214 may be laminated on one surface of the third sheet 213 .

Accordingly, only a portion of each of the fourth micropores O4 may overlap a portion of the second overlapping area SP2 adjacent in the third direction d.

A portion of each of the fourth micropores O4 may overlap a portion of the second overlapping area SP2 in the third direction d. A portion of the fourth micropore O4 overlapping a portion of the second overlapping area SP2 may be referred to as a third overlapping area SP3 . In other words, each of the fourth micropores O4 may include a third overlapping area SP3 overlapping a portion of the second overlapping area SP2 .

The third overlapping area SP3 may be an area in which all of the first to fourth micropores O1 , O2 , O3 , and O4 overlap. Accordingly, air may pass through the first to fourth sheet papers 211 , 212 , 213 and 214 through the third overlapping area SP3 . The third overlapping area SP3 overlaps a portion of the second overlapping area SP2 , and the width SW3 of the third overlapping area is the width SW1 of the first overlapping area and the width SW2 of the second overlapping area. ) may be smaller than For example, the width SW3 of the third overlapping region may be about 1/4 times smaller than the first width W1 . Accordingly, the size of the third overlapping area SP3 may be about 1/16 times smaller than that of the first micropore O1 .

In an embodiment, the third overlapping region SP3 may be formed as the aforementioned flow hole 220 . Accordingly, as a plurality of sheet papers are stacked on the sheet paper assembly 210 , the width of the flow hole 220 may become smaller, and the producer may adjust the width of the flow hole 220 by adjusting the number of stacked sheet papers. In addition, by manufacturing the sheet assembly 210 by stacking a plurality of sheet papers, the thickness of the sheet paper assembly 210 may be increased. Accordingly, durability and/or strength of the mesh 200 may be improved.

At least one of the plurality of sheets included in the sheet assembly 210 may be made of a polyvinyl chloride (PVC) film. In this case, the polyvinyl chloride (PVC) film constituting the sheet may be a film to which an UltraViolet (UV) blocking agent is added during the manufacturing process. Alternatively, the polyvinyl chloride (PVC) film constituting the sheet paper may be coated with an ultraviolet (UltraViolet, UV) blocking agent after manufacturing. In addition, the polyvinyl chloride (PVC) film constituting the first to third sheet papers 211 , 212 , and 213 may be coated with antimicrobials.

Ultraviolet (UV) blocking agents and antibacterial agents added to or coated with polyvinyl chloride (PVC) film may serve to improve the durability of sheet paper in addition to their intrinsic UV (UV) blocking and antibacterial functions. That is, the UV blocker and the antibacterial agent may serve to maintain the shape of the guide holes and micropores perforated in the sheet without being deformed.

On the other hand, the sheet may be configured to further include another film for improving the quality of the polyvinyl chloride (PVC) film. For example, a polyurethane (PolyUrethane, PU) film or a polyethylene terephthalate (PET) film is applied to the surface of a polyvinyl chloride (PVC) film before the sheet paper is coated with an ultraviolet (UV) blocker or antibacterial agent. can be coated.

As such, when a polyurethane (PU) film or a polyethylene terephthalate (PET) film is coated on a polyvinyl chloride (PVC) film, cracks or scratches that may occur on the sheet over time after the insect screen 10 is installed are prevented. can do.

In addition, the sheet may have a transparent color that can transmit light. However, the present invention is not limited thereto, and the sheet paper may have various colors depending on the characteristics of the building in which the insect screen 10 is installed, the characteristics of the geographical location, or the required air flow rate.

As described above, the second sheet 212 may be laminated on the first sheet 211 . In this case, a portion of the first micropores O1 of the first sheet paper 211 may overlap a portion of the second micropores O2 of the second sheet paper 212 . Accordingly, the sheet assembly 210 may include first overlapping regions SP1 in which the first micropore O1 and the second micropore O2 overlap. Also, the first overlapping regions SP1 may be flow holes 220 through which air passes. In an embodiment, the width SW1 of the first overlapping region is about 1/2 times smaller than the first width W1 of the first micropore O1 and the second width W2 of the second micropore O2. can Accordingly, the size of the first overlapping area SP1 may be about 1/4 times smaller than that of the first micropore O1 and the second micropore O3 .

The nonwoven filter 240 is a filter capable of collecting fine dust. The non-woven fabric filter 240 may be a filter manufactured by melting a thermoplastic polymer and extruding it through a nozzle.

Preparing the sheets ( S100 ) may include punching each of the sheets 211 , 212 , 213 , and 214 to form micropores O1 , O2 , O3 , and O4 . Each of the plurality of sheet papers 211 , 212 , 213 , 214 includes a first region P1 having micropores O1 , O2 , O3 , and O4 and micropores O1 , O2 , O3 and O4 . It may include an absent second region P2. The second region P2 may surround an edge of the first region P1 . Each of the micropores O1 , O2 , O3 , and O4 of the sheet papers 211 , 212 , 213 and 214 may be square in terms of flat size, but is not limited thereto. In an embodiment, the length and/or width of each of the micropores O1, O2, O3, and O4 may be L, and the size may be ^{L 2 .}

The micropores O1, O2, O3, and O4 may be arranged in a grid pattern. Using the first sheet 212 as an example, as shown in FIG. 8A , the first sheet 212 may include first micropores O1 . The first micropores O1 may be arranged at regular intervals along the first direction h1 and the second direction w.

Preparing the sheets ( S100 ) may include placing any one of the sheets 211 , 212 , 213 , and 214 on the base plate 300 . As shown in FIGS. 8A and 8B , the first sheet paper 211 having the first micropores O1 may be positioned on the base plate 300 . Each of the first micropores O1 may have a first width W1 . In addition, the first sheet 212 may include a first partition area positioned between the first micropores O1 adjacent to each other.

Forming the sheet assembly (S200) may include sequentially stacking a plurality of sheet papers (211, 212, 213, 214). When stacking a plurality of sheet papers, the sheets may be stacked so that a portion of each of the micropores O1, O2, O3, and O4 adjacent to each other overlaps.

In an embodiment, the step of forming the sheet paper assembly (S200) is to laminate the second sheet paper 212 on the first sheet paper 211. It may include laminating the third sheet 213 on the second sheet 212 and laminating the fourth sheet 214 on the third sheet 213 .

As shown in FIGS. 9A and 9B , a second sheet paper 212 having second micropores O2 may be stacked on one surface of the first sheet paper 211 . The second sheet 212 may be stacked on one surface of the first sheet 211 so that a portion of each of the second micropores O2 overlaps a portion of each of the first micropores O1 . Accordingly, each of the second micropores O2 may include a first overlapping region SP1 in which a portion overlaps a portion of the first micropore O1 .

In an embodiment, the second sheet 212 may include a second partition area positioned between the second micropores O2 adjacent to each other. The second sheet paper 212 may be stacked on the first sheet paper 211 such that the second partition area overlaps the central area of the first micropores O1 . Accordingly, one second micropore O2 may partially overlap the four first micropores O1 adjacent to each other. As illustrated in FIG. 9A , the second micropores O2 may include four first overlapping regions SP1 arranged in a grid pattern.

The width SW1 of the first overlapping region may be smaller than the first width W1 of the first micropore O1 and the second width W2 of the second micropore O2 . In an embodiment, the first width W1 and the second width W2 may be substantially the same. The width SW of the first overlapping region may be about 1/2 times the first width W1 and/or the second width W2. In addition, the size of the first overlapping area SP1 in terms of flat size may be about 1/4 times the size of the first micropore O1 and the second micropore O2 . Accordingly, by stacking the two sheet papers 212 and 212 , the mesh 200 may obtain a flow hole 220 having a size of about 1/4 times that of the micropores O1 and O2.

As shown in FIGS. 10A and 10B , a third sheet of paper 213 having third micropores O3 may be stacked on one surface of the second sheet of paper 212 .

The third sheet 213 may be stacked on one surface of the second sheet 212 so that a portion of each of the third micropores O3 overlaps a portion of the first overlapping region SP1 . Accordingly, each of the third micropores O3 may include a second overlapping area SP2 in which a portion overlaps a portion of the first overlapping area SP1 .

In an embodiment, the third sheet 213 may include a third partition area 2131 positioned between the third micropores O3 adjacent to each other. The third sheet paper 213 may be stacked on the second sheet paper 212 such that the third partition area 2131 overlaps the central area of the first overlapping areas SP1 . For example, one third micropore O1 may overlap a portion of nine first overlapping regions SP1 adjacent to each other.

As illustrated in FIG. 10A , nine first overlapping regions SP1 overlapping one third micropore O3 may be arranged in a grid pattern. In addition, the third micropore O3 may overlap the four first overlapping areas SP1 by about 1/4 and overlap the four first overlapping areas SP1 by about 1/2. have. Also, all of the third micropores O3 may overlap one first overlapping area SP1 . Accordingly, the second overlapping area SP2 includes the first area SP21 completely overlapping the first overlapping area SP1 and the second area SP22 overlapping the first overlapping area SP1 by about 1/2. and a third area SP23 overlapping the first overlapping area SP1 by about 1/4.

The size of the first area SP21 is about 1/4 times the size of the micropores O1, O2, and O3, and the size of the second area SP22 is the same as the size of the first micropores O1, O2, and O3. It is about 1/8 times, and the size of the third region SP23 may be about 1/16 times the size of the micropores O1, O2, and O3.

The width SW2 of the second overlapping area may be less than or equal to the width SW1 of the first overlapping area. In an embodiment, the width SW21 of the first area SP21 may be the same as the width SW1 of the first overlapping area. Also, the width SW23 of the second area SP22 and the third area SP23 may be smaller than the width SW1 of the first overlapping area. The second overlapping area SP2 may be an area penetrating through the first to third sheet papers 211 , 212 , and 213 . Accordingly, air may pass through the first to third sheet papers 211 , 212 , and 213 through the second overlapping area SP2 .

The fourth sheet 214 may be stacked on one surface of the third sheet 213 so that a portion of each of the fourth micropores O4 overlaps a portion of the second overlapping area SP2 . Accordingly, each of the fourth micropores O4 may include a third overlapping area SP3 in which a portion overlaps a portion of the second overlapping area SP2 .

In an embodiment, the fourth sheet 214 may include a fourth partition area 2141 positioned between the fourth micropores O3 adjacent to each other. The fourth sheet 214 may be stacked on the third sheet 213 such that the fourth partition area 2141 overlaps the center area of the second overlapping areas SP2 . For example, it may overlap a portion of each of the 16 adjacent second overlapping areas SP2 . As illustrated in FIG. 11A , 16 second overlapping areas SP2 overlapping one fourth micropore O4 may be arranged in a grid pattern.

In an embodiment, the fourth micropore O4 may overlap by the same size as the 16 adjacent second overlapping areas SP2 . Accordingly, the size of the third overlapping area SP3 in terms of flat size may be about 1/16 times the size of the first micropore O1 .

The third overlapping area SP3 may penetrate the first to fourth sheet papers 211 , 212 , 213 and 214 . Accordingly, the third overlapping area SP3 may be the flow hole 220 of the sheet paper assembly 210 . Also, as described above, the size of the third overlapping region SP3 may be about 1/16 times the size of the micropores O1 , O2 , O3 , and O4 . Accordingly, it can be seen that when the sheet papers are stacked 4 times rather than stacked twice, the size of the flow hole 220 is reduced.

After the plurality of sheet papers 211 , 212 , 213 , and 214 are all stacked, the edge of the sheet paper assembly 210 may be formed to be stepped. This is because each of the same sheet papers 211 , 212 , 213 , and 214 are stacked slightly shifted from each other. As the edge of the sheet paper assembly 210 is stepped, the screen 200 for the insect screen may not be accurately installed in the screen frame 100 . Accordingly, it is preferable to remove the step portion from the edge of the sheet paper assembly 210 . In an embodiment, the above-described step difference may be removed by removing an area where all of the sheet papers 211 , 212 , 213 , and 214 do not overlap among the edge regions of the sheet paper assembly 210 .

In the embodiment, an area where the edge area of the first sheet paper 211, the edge area of the second sheet paper 212, the edge area of the third sheet paper 213, and the edge area of the fourth sheet paper 214 do not all overlap can be removed Accordingly, the edge of the sheet paper assembly 210 may be formed parallel to the third direction (d). That is, the edge portion of the stepped sheet paper assembly 210 may be removed.

The step of attaching the nonwoven filter 240 includes separating the base plate 300 from the sheet paper assembly 210 and attaching the nonwoven filter 240 to the innermost sheet or the outermost sheet of the sheet paper assembly 210 . can do. Alternatively, in another embodiment, the step of attaching the nonwoven filter 240 includes laminating the nonwoven filter 240 on the first sheet 211 and laminating the second sheet 211 on the nonwoven filter 240 . may include doing

The step of forming the guide hole 230 ( S400 ) may include removing a portion of the edge region of the sheet paper assembly 210 , and then punching the region of the sheet paper assembly 210 in which the flow holes 220 are not formed. have. Guide holes 230 may be formed in areas of the sheet paper assembly 210 in which flow holes 220 are not formed through punching.
