Description

Prefabricated wide ceiling panel and its manufacturing apparatus and method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel, which is a ceiling material installed on a ceiling, and the like, and more particularly, to a prefabricated wide ceiling panel that is fabricated in a size larger than a usual predetermined size and that can be built prefabricated.

Conventional ceiling panels are made of ribs, which are reinforcing materials installed vertically between the upper and lower plates and the upper and lower plates. Most panels have a width of 300mm and a height of 10mm between the top and bottom of the panel. And the top and bottom of the ceiling panel is about 0.8-1mm thick, but most of the thickness of 1mm P.V.C. It is made of materials such as

The ribs installed vertically at the height between the upper and lower plates are installed at intervals of about 12 to 15 mm, which are more narrowly about 13 to 15 mm, but are generally installed at intervals of about 14 mm.

In the conventional ceiling panel, the biggest reason for not making the width width larger than 300mm is the strength problem. In other words, if the width of the panel to be made more than 300mm in size, the thickness should be made thicker, causing a rise in the cost of the material cost and the difficulty of manufacturing accordingly.

For example, if you make a panel with a width of 300mm or more, for example, a width panel with a width of about 500mm or more, inevitably, the height between the top and bottom of the panel should be increased by about 12 It has been used to thicken up to 15mm. Therefore, these products are not compatible with 10mm panels, and they are difficult to mix and use in areas where panels of 10mm thickness are used, and even if they are installed, there is a step in the installation part due to the difference in thickness after installation. Not only is it difficult to finish with rim molding, but it looks unsightly

In addition, in the conventional case, the surface of the UV coating on the panel is treated, in which case the coating surface is uneven or the surface hardening does not occur smoothly during the curing treatment after the coating treatment has a high incidence of defects

In addition, the conventional panel is difficult to connect at the connecting parts at the left and right ends of each panel, and when the panel is fixed with a piece, etc., the connection at the connecting part may not be smooth due to the fixed piece. Concentration of force occurs and often breakage occurs.

The present invention has been invented in view of the above, and has developed a product that can be mixed with an existing panel having a width of 10 mm and a thickness of 10 mm without any problems in strength.

In addition, the present invention has developed a new technology in the processing of pearls and UV in order to further refine the product

In addition, the present invention has developed a technology that the surface is uniform when the UV coating surface treatment on the panel surface and the surface hardening is smooth during the curing treatment after the coating treatment, the connection is easy at the left and right connection parts of the panel and the connection part Provides panels with no damage

A left coupling part 30 which is continuous with the tomographic part 2 and constitutes an upper surface 1 which forms a flat plate at a higher height than the tomographic part 2; A right protrusion 25 having a priority bend portion 21 protruding to the right front side and protruding to a smaller size than the right protrusion 25 is formed in the opposite direction to the left coupling portion 30. And a right coupling part 40 having a lower protrusion part 26 configured to form a groove in an upper portion thereof, wherein the second protrusion 4 of the left coupling part 30 has a curved surface at its tip end thereof. And a lower curved portion 14, wherein the connection portion between the tomographic portion 2 and the upper surface 1 includes an upper curved portion 15 formed of a convex curved surface. 30, the tip of the lower protrusion 26 includes a lower right curved part 22 formed of a curved surface, and the ribs 8 are not included in the right protrusion 25 of the right coupling part 40. , When installing the fixture including the piece 11, the right projection 25 is crushed to reduce the thickness The prefabricated panel has a width of 400 mm to 600 mm, a total thickness of 10 mm, and a thickness of the upper and lower surfaces 1 and 7 forming the upper and lower plates is 0.6 to 600 mm. 0.7 millimeters, and the distance between the ribs is 8 to 12 millimeters, and in the prefabricated wide ceiling panel manufacturing apparatus, the metal roll 51 and the metal roll 51 are provided adjacent to the silicon A coating roll 52 made of a material and a liquid spreader 55 provided between the metal roll 51 and the coating roll 52 to supply a coating solution for the UV coating, and by the coating roll 52. The primary coating device for applying the upper surface of the ceiling panel 10, the metal roll 54, the second coating roll 53, which is installed adjacent to the metal roll 54 and made of a silicon material, the metal It is installed between the roll 54 and the second coating roll 53 to supply the UV coating liquid.

In order to increase the curing efficiency, the air supply by the air supply unit 61 on both sides of the curing unit 50 and the exhaust by the exhaust unit 65 at the upper portion of the curing unit 50 to exhaust heat inside the curing unit. As presented Ex it've characterized in that for curing it.

Other features and configurations other than those described above will be described in detail below with reference to the accompanying drawings.

According to the present invention, it is possible to provide a wider panel with a thickness of about 10 mm, which is thin and light, but without problems of strength. That is, it provides a panel which is light in size and which can maintain a desired strength.

According to the present invention, it is possible to produce a wider panel than the conventional one without thickening the thickness of the panel, so that the work is facilitated quickly when installing the ceiling, etc. and provides a more beautiful appearance after installation.

According to the present invention, although the panel of 500 mm or more in width is generally used, the panel of 300 mm in width and its height are generally the same and can be used interchangeably.

In addition, the present invention contemplated that the weight of the overall panel is not greatly increased by adjusting the width of the ribs and controlling the thickness of the upper and lower panels. Breaking common sense in the art, it was possible to achieve a light weight by adjusting the number and width of ribs that dare not think.

In addition, according to the manufacturing method and apparatus according to the present invention, it is possible to perform a UV coating very smoothly and to produce a high-quality finished product with little coating defect rate. For example, in the case of pearl coating and silver nano coating, there is an advantage that even one coating can be pearl coating or silver nano coating without two coatings, and the defect rate can be greatly reduced in coating and curing treatment.

In addition, according to the present invention, the ceiling panel is easily fixed and connected at the connecting portions at the left and right ends of the panel, and there is almost no defect in the connecting portion.

Figure 4 shows a curing device according to the invention for curing after UV coating.
5 is a view for explaining that the UV coating is made in 1 and 2 in accordance with the present invention

Hereinafter, the present invention will be further described based on the accompanying drawings.

1 is a diagram illustrating a configuration of a ceiling material according to the present invention.

As shown, the present invention constitutes connecting portions at both left and right ends. For example, on the left side, a rather thin tomographic portion 2 is formed at the tip, and the tip protrusion 3 is continuously formed at the rear side, and a protrusion 5 is formed at the rear of the tomographic portion 2 to form an upper surface ( Consist with 1). Small protrusions 6 are formed between the upper surface 1 and the protrusions 5, that is, adjacent to the protrusions 5.

In addition, all of the folded parts are curved. That is, the tip curved portion 13 is formed at the tip, the lower curved portion 14 is formed at the lower portion thereof, and the upper curved portion 15 is formed at the right side of the tomographic portion 2. The tip bent portion 13 is for allowing the tip portion to be inserted smoothly and easily when fitting with other members, and the lower bend portion 14 and the upper bent portion 15 have good fit at the joining portion with the other member to be joined. In addition, even if an impact is applied at the coupling site, damage caused by partial concentration of impact load is to prevent breakage. The rib 8 is reinforced between the upper surface 1 and the lower surface 7.

The ceiling panel 10 configured in the present invention has a width dimension of 400 mm (mm) to 600 mm, preferably 550 mm, and the thickness formed by the upper and lower surfaces is 10 mm as in the prior art. The gap between the ribs is 8-12 mm. Preferably it is 10 mm. If it is more than 10mm, even if the strength is increased, it may cause material cost increase, which is not preferable.

In this way, when the interval between the ribs 8 is narrowed, the strength is increased, so that the thickness of the upper and lower plates can be made thinner. That is, the upper and lower plates 1 and 7 according to the present invention have a thinner thickness of about 0.6 to 0.7 mm, but the resistance to warpage does not drop as compared with the prior art. That is, in the present invention, since the distance between the ribs 8 is relatively smaller than that of the prior art, the overall thickness between the top surface 1 and the bottom surface 7 is maintained at about 10 mm as in the prior art without increasing the overall thickness between the upper and lower surfaces 10 mm or more. The strength can be maintained. Note that the ceiling panel does not receive a specific load on its top surface, so it is not necessary to maintain the strength to support large loads.

2 is a cross-sectional view of main parts of the connecting portion in the case of interconnecting two panels according to the present invention.

As shown in the drawing, the right end of the panel includes a right protrusion 25 in which the first bent portion 21 is formed, and a lower protrusion 26 which protrudes in a somewhat shorter length and has a lower right portion 22 at its tip. . Due to this configuration, the left coupling portion 30 configured on the left side of the single plastic panel and the right coupling portion 40 configured on the right side are configured to interconnect the two panels.

Returning back to FIG. 1, when fixing the ceiling panel 10 to the ceiling, a piece 11 or other fixing member is used, in which case the right protrusion 25 of the right coupling portion 40 is moved from below. Drive with piece (11). Then, as shown in Figure 3, the piece 11 is fixed while reducing the thickness of the right protrusion 25 while crushing the right protrusion 25. Then, the first bent portion 21 can be easily fitted under the right protrusion 25. Therefore, the rib 8 should not be provided in the right protrusion part 25. FIG.

If the ribs 8 are installed, if the ribs 8 are broken or the right projections 25 do not reduce their thickness, the head of the piece 11 protrudes downward, causing the lower right corner 22 of the other plastic panel to break. This prevents them from being plugged in, which in turn makes continuous connection of the other members impossible.

The present invention of the above structure has another feature in its manufacture

In other words, U.V. is applied to the surface of the panel and cured, but there is another feature in the manufacturing process.

In the present invention, silver nanoparticles having an antimicrobial property or pearl are mixed together with the UV coating solution before the UV coating. The reason why silver nano coating is, for example, is to prevent such a panel used for ceilings, such as a bathroom, because moisture is always filled and mold occurs in the panel, and mixing of pearls is to improve aesthetics.

The disinfectant, antimicrobial, deodorant, far infrared and anion emission effects of silver nano are already known effects, and thus detailed description thereof will be omitted.

For example, the silver nanoparticle size is about 1 nanometer. The mixing method and ratio of the silver nanoparticles with respect to the UV coating liquid are mix | blended 50 g of silver nanoparticles with 1 kg of UV coating liquids with a stirrer. Increasing the compounding ratio further to around 10% does not adversely affect the UV coating effect.

As another example, in order to produce a pearl printing effect using a UV solution, the pearl is mixed, and the particle size of the pearl is preferably about 1 to 15 um, and the color of the pearl is various colors such as silver and gold. Can be used

Mixing method and proportion of the pearl particles is put into the UV coating solution and the pearl particles are constantly blended with a stirrer, according to the desired color concentration to adjust the pearl blending ratio between about 10 to 50% concentration. (I.e. blending 100 ~ 1,000g of pearl to 1Kg of UV coating solution) Work method is the same as UV coating method. In general, instead of the two-step operation of printing the pearl and the second UV coating after the pearl effect, according to the present invention there is an advantage that the printing effect can be achieved simultaneously by omitting the printing step and only the UV coating operation step.

Moreover, in this invention, it has the characteristics also in application | coating and hardening of UV, its UV processing speed | rate, etc. UV investigations to achieve the present invention have undergone many trials and errors. In other words, if the UV irradiation is too short or long, good quality is hard to come out

If the conventional general UV treatment technology is applied as it is, the irradiation amount is too large, the UV is excessively hardened and changed to a yellow color, or vice versa, there is a problem in that the irradiation dose is insufficient to prevent complete irradiation and hardening treatment. In addition, it was found that the deformation of the panel surface treatment due to the heat generated in the lamp was also found. Therefore, UV dose and irradiation time are important variables, and heat treatment is a problem.

In the present invention, the invention further invented the heat dissipation device for the production of good products.

That is, if the heat dissipation device is configured, overheating can be prevented, and the UV irradiation and curing time can be further shortened to further increase productivity.

4 schematically shows the UV curing machine 50 used in the present invention.

As shown in the drawing, only two irradiation lamps 41 are operated by using two UV probes. When two are used, the curing is fast but several disadvantages arise. That is, after the irradiation by the primary irradiation lamp 41, when the panel is heated by the other irradiation lamp secondly while moving, after a certain distance movement, it is reheated secondly, so that uniform curing is difficult and excessively excessive heat is also generated in the irradiation lamp. It is not desirable to cause excessive deformation due to deterioration of the product.

The advancing speed of the input panel is preferably 1.2 to 1.3 meters per minute. If it is faster than the speed, the yuv may not be applied and hardened properly. On the contrary, if the speed is slower than the speed, the color may turn yellow due to excessive hardening and the panel may be deteriorated.

In the present invention, a heat dissipation device is configured to remove heat generated in the curing machine 50. As shown in the drawing, both sides of the device constitute an air supply device 61 for injecting air, and the upper part is exhausted. The exhaust device 65 is configured. The exhaust of the exhaust device 65 is exhausted at two places before and after the irradiation lamp 41, thereby enabling the first heat radiation and the second heat radiation of the ceiling panel 10 to be advanced. In addition, injecting air to the side with respect to the traveling direction of the panel is more effective for heat dissipation, and it is more effective to exhaust the high temperature internal heat to the upper side according to the natural circulation principle.

The present invention is also characterized in the application of UV.

As shown in FIG. 5, when the ceiling panel 10 is supplied, one side, that is, the bottom surface 7 that is exposed to the outside, is coated with the application liquid 52. UV solution has already been described above may optionally include pearl or silver nano particles. When the yuv liquid is supplied from the liquid spreader 55, it is supplied between the metal roll 51 and the application roll 52 made of a silicon material, and when the yuv liquid is coated on the application roll 52, the application roll 52 Is in contact with the surface of the incoming ceiling panel 10 to cover the UV solution. Then, the UV liquid is applied to the second coating device composed of the same device and applied secondly. The preceding road roll 52 rotates in the same direction as the traveling direction of the ceiling panel 10, but in the second coating device, the second coating roll 53 rotates in the opposite direction to the traveling direction of the ceiling panel 10. Thus, the UV liquid applied to the surface of the ceiling panel 10 is scraped off and the UV liquid supplied from the liquid spreader 58 is applied secondly.

The reason for doing this is that the UV coating applied previously serves to flatten the coating on the ceiling panel, and the surface is partially coated or uncoated depending on the situation of the application roll 52. This is to more reliably apply.
