It is a perspective view schematically showing the foaming machine of the antiviral mat manufacturing system according to an embodiment of the present invention.

1 to 3, the antiviral mat manufacturing system used in the mat manufacturing method using the antiviral mat manufacturing system according to an embodiment of the present invention includes a plurality of carrier molds 100 and a foaming machine 200. and may further include a turntable 100.

The carrier mold 300 is a mold device for molding the antiviral mat.

The carrier mold 300 includes a base plate 310, an air bag 320, a pressure plate 330, a lower mold plate 340, a side wall frame 350, a mold upper plate 360, a cover frame 370, and a hot water tube. (345).

The base plate 310 provides support for supporting the air bag 320, the pressure plate 330, the lower mold plate 340, the side wall frame 350, the upper mold plate 360, and the cover frame 370 disposed on the upper side. By doing so, it provides a support base on which an antiviral mat (hereinafter referred to simply as 'mat') can be molded.

This base plate 310 is preferably made of a flat plate. And as referenced in the drawings, a form in which the base plate 310 is disposed on the upper side of the mount frame 302 is also possible. The mount frame 302 supports the base plate 310 .

The mount frame 302 may be provided with a plurality of support scaffolds 304 . Each of the plurality of support plates 304 is preferably adjustable in height.

When the base plate 310 disposed on the upper side of the mount frame 302 is horizontal, there is no or weak dynamic flow of the foam liquid injected into the lower mold plate 340 and the side wall frame 350, resulting in foaming during the molding process. As the liquid is not evenly spread inside when it is expanded, a problem that the shape of the molded mat may be molded into an abnormal shape may occur. In addition, a problem may occur that the hardness of the mat is not uniform as a whole and may be different for each part. In addition to this, there is a possibility that other molding problems may occur.

In view of this problem, when the foam liquid is foamed inside the mold lower plate 340 and the sidewall frame 350, the base plate disposed on the upper side of the mount frame 302 to spread the foam liquid evenly over the entire area ( 310) may be inclined at a predetermined angle. Therefore, it is preferable that the base plate 310 can be set to be inclined at a predetermined angle by individually adjusting the height of each of the plurality of support plates 304 .

The airbag 320 is disposed on the upper surface of the base play. The airbag 320 may be inflated by air injected from the outside. Here, although not shown in the drawings, an air supply device for supplying air to the air bag 320 from the outside may be further included in the mat manufacturing system.

When the airbag 320 is inflated during molding of the mat, the lower mold plate 340, the side wall frame 350, and the mold upper plate 360 are brought into close contact with each other by the pressure generated by the airbag 320 expansion. After forming the mat, the air injected into the airbag 320 may be discharged to the outside.

The pressure plate 330 is disposed above the air bag 320 and below the lower mold plate 340 . That is, the pressure plate 330 is disposed between the air bag 320 and the lower mold plate 340 in a form interposed therebetween. The pressure plate 330 pressurizes the mold lower plate 340 upward by the expansion of the air bag 320 .

The pressure plate 330 suppresses the pressure applied to the lower mold plate 340, the side wall frame 350, and the upper mold plate 360 by the airbag 320 from being concentrated on a specific part and applies evenly to each part. The pressure is transmitted to the lower mold plate 340 by dispersing.

The mold lower plate 340 serves as a mold in which the lower side portion of the mat to be manufactured can be molded. The lower mold plate 340 is disposed above the airbag 320. More specifically, it is disposed on the upper side of the pressure plate 330 disposed on the upper side of the airbag 320.

The side wall frame 350 serves as a mold on which the circumferential portion of the side of the mat to be manufactured can be molded. This side wall frame is disposed on the upper side of the lower mold plate 340 . The side wall frame 350 may have various shapes in consideration of the shape of the edge of the mat to be molded and the shape of the lower plate of the mold. In the drawing, the shape of the side wall frame 350 is a square It is shown having the shape of a ring, but is not limited to this shape. Therefore, it can be said that the side wall frame 350 is sufficient as long as it can serve as a mold for molding the side circumferential portion of the mat to be manufactured.

The upper mold plate 360 serves as a mold in which the upper side portion of the mat to be manufactured can be molded. The upper mold plate 360 may form an airtight space in which the mat is molded together with the lower mold plate 340 and the side wall frame 350 while being in contact with the upper side of the side wall frame 350 .

That is, the molding of the mat is performed in the closed space formed by the lower mold plate 340, the side wall frame 350, and the upper mold plate 360.

The mold top plate 360 is coupled to the cover frame 370 , and the mold top plate 360 is supported by the cover frame 370 . The upper mold plate 360 is hinged with the base plate 310 to serve as a cover that selectively opens or closes the inner space of the lower mold plate 340 and the side wall frame 350 .

A fixing member 382 is provided on the cover frame 370 . In addition, a latch 384 corresponding to the fixing bar 382 of the cover frame 370 is provided on the base plate 310 .

Fixing bars 382 provided on the cover frame 370 are for fixing the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 to be compressed. As referenced in the drawing, the fixing member 382 is provided at the front end of the cover frame 370 whose rear end is hinged with the base plate 310.

The cover frame 370 to which the upper mold plate 360 is coupled may be rotated around a hinged portion with the base plate 310 . Accordingly, the cover frame 370 is opened or closed with respect to the base plate 310, centered on the hinge axis.

In addition, the fixing member 382 is caught on the holding member 384 provided on the base plate 310 so that the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 may be pressed or brought into close contact with each other.

Hot water tubes 345 are provided in the mold upper plate 360 and the mold lower plate 340 to supply the temperature required for molding the mat, that is, heat. At least a portion of the hot water tube 345 is embedded in or attached to the upper mold plate 360 or the lower mold plate 340 . Then, the hot water tube 345 transfers the heat of the hot water introduced from the outside to the upper mold plate 360 or the lower mold plate 340 . Here, although not shown in the drawing, a hot water supply device for supplying hot water to the hot water tube 345 from the outside may be further included in the mat manufacturing system.

As the heat of the hot water is transferred to the upper mold plate 360 and the lower mold plate 340, the upper mold plate 360 and the lower mold plate 340 rise to the mat molding temperature, which is the temperature necessary for molding the mat, and the mat is heated at the molding temperature. shaping takes place.

A guider 390 may be further included in the carrier mold 300 as described above. The guider 390 guides the upward movement of the pressure plate 330 so that the pressure plate 330, which is moved upward by the inflation of the air bag 320 and presses the lower mold plate 340, moves upward while maintaining a horizontal position. Since the pressure plate 330 is moved upward while maintaining a level by the guider 390, the pressure applied to each part of the lower mold plate 340 becomes uniform.

If the pressure plate 330 does not remain horizontal and is moved obliquely upward, the pressure applied to each part of the lower mold plate 340 is different, so that the lower mold plate 340, the side wall frame 350, and the upper mold plate 360 It is difficult to seal the closed space formed by the mat, and the outer shape of the molded mat may not be formed correctly. Therefore, it is preferable that the pressure is uniformly applied to the lower mold plate 340 by moving the pressure plate 330 upward while maintaining a horizontal level.

The guider 390 is not limited to a specific shape and is sufficient as long as it can guide the pressure plate 330 to move upward while maintaining a horizontal level. The drawing shows a guide cylinder as a preferred example of the guider 390.

A plurality of carrier molds 300 as described above may be disposed on the turntable 100 as referenced in the drawings.

That is, the mat manufacturing system further includes a turntable 100 for rotating the plurality of carrier molds 300 so that the plurality of carrier molds 300 can sequentially receive the foaming liquid, which is the raw material of the mat, from the foaming machine 200. that it includes As referenced in the drawings, the plurality of carrier molds 300 are preferably arranged spaced apart from the center of rotation of the turntable 100 by a predetermined interval.

The turntable 100 rotates so that the positions of the plurality of carrier molds 300 disposed thereon are cyclically changed. After the raw material of the mat is injected from the foaming machine 200 into the lower mold plate 340 and the side wall frame 350, the mold upper plate 360 is in contact with the side wall frame 350, and the mold upper plate 360, side wall frame 350 Molding of the mat is performed in a space closed by the wall frame 350 and the lower mold plate 340, and the mold upper plate 360 remains covered with the upper side of the side wall frame 350 until the mat is formed. while rotating according to the rotation of the turntable 100.

When the raw material of the mat is injected from the foaming machine 200 into one carrier mold 300, the raw material of the mat is injected into the next carrier mold 300. As such, the turntable 100 rotates so that the raw material of the mat can be sequentially injected into the plurality of carrier molds 300 .

Therefore, the amount of mat production per unit time can be increased, and since the turntable 100 rotates the plurality of carrier molds 300, the space required to manufacture the mat using the plurality of carrier molds 300 can be reduced.

It is preferable that the rotational speed of the turntable 100 is set so that the maturation time, that is, the time for completing the molding is shorter than the time required for the turntable 100 to rotate once. After the aging time, the upper mold plate 360 covering the lower mold plate 340 and the sidewall frame 350 is opened, and the molded mat is taken out.

The foamer 200 injects a raw material for molding the mat into a molding space formed by the upper mold plate 360 , the side wall frame 350 and the lower mold plate 340 . A preferred form of this foaming machine 200 is shown in the drawing, but is not limited to this form. If the raw material for molding the mat can be injected into the molding space formed by the upper mold plate 360, the side wall frame 350, and the lower mold plate 340, the foaming machine 200 of the present invention can be made.

The foaming machine 200 supplies polyol and methylene diphenyl diisocyanate (MDI), which are raw materials of the mat, to the carrier mold 300.

The foaming machine 200 includes a polyol supply tank 210, an MDI supply tank 220, a polyol agitator 230, an MDI agitator 240, and a foaming nozzle 250.

The polyol supply tank 210 stores polyol, which is a raw material of the foaming liquid. The polyol stored in the polyol supply tank 210 is discharged through the foaming nozzle 250 and injected into the molding space of the carrier mold 300 described above.

The polyol agitator 230 disposed on the upper side of the polyol supply tank 210 continuously agitates the polyol to suppress the formation of precipitates or hardening.

The MDI supply tank 220 stores MDI (Methylene diphenyl diisocyanate), a raw material of the foaming liquid. MDI stored in the MDI supply tank 220 is discharged together with polyol through the foaming nozzle 250 and injected into the molding space of the carrier mold 300 described above.

The MDI stirrer 240 disposed on the upper side of the MDI supply tank 220 continuously agitates the MDI to suppress generation of precipitates or hardening of the polyol raw material.

An antiviral mat manufacturing method using the antiviral mat manufacturing system as described above will be described with further reference to FIG. 4 .

4 is a flowchart schematically showing a mat manufacturing method using an antiviral mat manufacturing system according to an embodiment of the present invention.

4, the mat manufacturing method using the antiviral mat manufacturing system according to an embodiment of the present invention includes a preparation step (S110), a release material arrangement step (S120), a skin material arrangement step (S130), and a molding step (S140). ), and a withdrawal step (S150).

The preparation step (S110) is a step of raising the temperature of the carrier mold 300 to the mat forming temperature in the mat manufacturing system including a plurality of carrier molds 300 and foaming machines 200. That is, hot water is supplied to the hot water tube 345 of the carrier mold 300 to supply heat to the lower mold plate 340 and the upper mold plate 360 to raise the mat forming temperature, which is a temperature at which the mat can be formed.

Subsequently, the release member arrangement step (S120) is a step of disposing the release member on the carrier mold 300 heated in the preparation step (S110). That is, a release member is disposed on the surface of the mold top plate 360 .

The release member allows easy separation between the mold top plate 360 and the molded mat after molding. Depending on the need for manufacturing the mat, a release member may be selectively disposed on the surface of the lower mold plate 340 and the inner surface of the sidewall frame 350.

Next, the skin material arrangement step (S130) is a step of disposing the skin material to form the skin layer of the mat on the carrier mold 300 on which the release material is disposed in the mold release material arrangement step (S120). Here, it is preferable that the skin material contains an antiviral component.

The skin material is preferably any one of TPU (Thermo plastic polyurethane), PU, TPE, TPO and PVC films containing at least one of zinc chloride, manganese chloride, calcium chloride and copper chloride as an antiviral component.

Here, the blending ratio of TPU, PU, TPE, TPO, and PVC films and the antiviral component is preferably 100: 3 to 5 based on the total weight.

This skin material is disposed on the inner surface of the lower mold plate 340 and the side wall frame 350.

Next, in the molding step (S140), the foaming liquid to form the foam of the mat is injected into the carrier mold 300 on which the skin material is disposed in the skin material arrangement step (S130) using the foaming machine 200, and then the carrier mold ( 300) is sealed and the foaming liquid is foamed for a predetermined maturation time to form a mat.

Foaming liquid is injected into the side wall frame 350 and the lower mold plate 340 where the skin material is disposed. Injection of the foaming solution may be performed using the foaming machine 200 as described above. Here, the foaming liquid is preferably formed by stirring polyol and MDI (methylene diphenyl diisocyanate) in the foaming machine 200.

After the foaming liquid is injected into the side wall frame 350 and the lower mold plate 340, the cover frame 370 is closed so that the upper mold plate 360 comes into contact with the side wall frame 350. In addition, the lock is hooked to the lock 384 so that the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 can be compressed or maintained in close contact. Since the lock is caught on the latch 384, the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 do not spread and maintain a compressed or closely adhered state even when the foam is foamed and inflated during the maturation time. .

Then, air is supplied to the airbag 320. When air is supplied to the airbag 320, the airbag 320 expands and the pressure plate 330 moves upward. Since the upwardly moving pressure plate 330 applies pressure to push the lower mold plate 340 upward, adhesion between the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 can be improved. Here, if the guider 390 is present in the carrier mold, the pressure plate 330 moves upward while maintaining the base plate 310 horizontally, so that the pressure applied to the lower mold plate 340 becomes uniform. When pressure is uniformly applied to the lower mold plate 340, the possibility of local gaps being generated is further reduced.

During the aging time, the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 maintain close contact. During the maturation time, the foamed liquid is molded into a foam and the skin layer is attached to the surface of the foam.

Meanwhile, after the foaming liquid is injected and the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 are brought into close contact, the turntable 100 is rotated. Until the aging time elapses, the upper mold plate 360, the side wall frame 350, and the lower mold plate 340 of the carrier mold 300 are maintained in close contact, and the turnable is rotated to rotate the next carrier mold ( 300), the preparation step (S110) to the molding step (S140) as described above proceed, and when the aging time elapses, the withdrawal step (S150) proceeds.

The withdrawal step (S150) is a step of withdrawing the mat formed in the molding step (S140) from the carrier mold 300. After the aging time has elapsed, when the cover frame 370 to which the upper mold plate 360 is coupled is opened, the lower mold plate 340 is separated from the side wall frame 350 and the inner side is opened, and the lower mold plate 340 and the side wall are opened. The molded mat is taken out from the inside of the frame 350.

As such, since the preparation step (S110) to the molding step (S140) and the withdrawal step (S150) are sequentially performed for each of the plurality of carrier molds, the number of mats manufactured per unit time is increased. Thus, the production efficiency of the mat is increased.

The mat manufactured by the mat manufacturing method described above is composed of a foam and a skin layer surrounding the foam.

The skin layer is preferably any one of TPU (Thermo plastic polyurethane), TPO, TPE, PU and PVC films. The skin layer has a thickness ranging between 10 micrometers and 500 micrometers and the foam has a thickness ranging between 5 and 105 millimeters. An antifouling treatment may be additionally performed on the skin layer.

In addition, as mentioned above, since the epidermal layer contains at least one of zinc chloride, manganese chloride, calcium chloride and copper chloride, it has an antiviral effect.

In this way, the mat manufacturing method using the antiviral mat manufacturing system according to the embodiment of the present invention can produce a mat having an antiviral effect, and furthermore, during the time the mat is molded in any one carrier mold 300, another carrier separately. Since the mat manufacturing method can be executed in the mold 300, the number of antiviral sheets produced per unit time increases. Therefore, there is an advantage of improving the production efficiency of the antiviral mat.

As described above, the specific description of the present invention has been made by the embodiments with reference to the accompanying drawings, but since the above-described embodiments have only been described with reference to preferred embodiments of the present invention, the present invention is the above It should not be understood as being limited only to the embodiments, and the scope of the present invention should be understood as the following claims and equivalent concepts thereof.
