Description

Technical Field

[0001] This invention relates to the field of bathroom flooring production technology, specifically to a moisture-proof laminated flooring and a laminating device. Background Technology

[0002] The development of bathroom flooring materials and processes has consistently revolved around three core requirements: waterproofing, slip resistance, and durability. From traditional ceramic glazed tiles and natural stone to the widely used modern SPC and WPC stone-plastic composite flooring, technological advancements have continuously broadened the choices for bathroom flooring. Among them, composite flooring based on polymers is increasingly used in shower rooms due to its good dimensional stability, rich decorative textures, and relatively convenient installation. To give these floors stronger resistance to water vapor erosion, the industry generally adopts the process of covering or coating their surface with waterproof and moisture-proof functional layers. Correspondingly, the coating technology and specialized production equipment have also evolved from early simple decorative films to surface treatment devices with certain waterproof functions, aiming to improve the inherent moisture resistance of the substrate.

[0003] However, existing lamination processes and equipment for bathroom floors have significant limitations, restricting the reliability and durability of the final moisture-proof effect. Most lamination equipment focuses solely on the decorative or wear-resistant layer of the walking surface, completely neglecting the harsh conditions of a bathroom environment where moisture permeates from all directions. This leaves the floor edges, locking joints, and bottom directly exposed to the humid environment, becoming weak points for moisture intrusion. Over time, this easily leads to problems such as edge warping, mold growth at the locking joints, or internal swelling of the substrate due to moisture. Even solutions attempting multi-faceted floor treatment face insurmountable engineering challenges: for example, when applying liquid waterproof coating to the bottom surface, the coating adheres to the production line conveyor before curing, damaging the coating integrity and contaminating the equipment; and when treating the four sides of the floor, there is a lack of effective means to provide precise lateral positioning during spraying without contaminating the uncured coating. These drawbacks mean that so-called "waterproof floors" produced by existing technologies often fall short of the advertised claim, failing to meet the stringent long-term, overall moisture-proof performance requirements of the bathroom environment.

[0004] Therefore, given that existing technologies cannot provide truly comprehensive six-sided moisture-proof sealing for bathroom floors, and that key technical obstacles such as adhesion, positioning, and interference exist in the bottom and side treatment processes, there is an urgent need for fundamental improvements and optimizations to the overall structural design and process flow of the coating device. There is a pressing need to invent a dedicated coating device that can systematically solve the above problems. Through innovative zoned processing, dynamic positioning, and synergistic curing strategies, it can achieve comprehensive, high-quality, and defect-free waterproof coating for bathroom floors, thereby producing truly durable and reliable moisture-proof flooring products that can withstand the high humidity environment of bathrooms.

Multiple sets of second side positioning wheels are rotatably connected to the inner left and right walls of the upper chambers of the second laminating box and the second curing box. The horizontal height of the second side positioning wheels is configured such that their supporting surfaces are below the center of the thickness of the processed material.

[0007] Preferably, the inner front wall and inner rear wall of the bottom box of the first coating box are fixedly connected to a first bracket, and the upper wall of the first bracket is fixedly connected to a first lower nozzle for spraying the area of ​​the lower wall of the floor body other than the contact with the first conveying roller and a first side nozzle for spraying the area of ​​the side wall of the floor body other than the contact with the first side positioning wheel; the inner wall of the upper box of the first coating box is fixedly connected to a second bracket, and the lower wall of the second bracket is fixedly connected to an upper nozzle for spraying the upper wall of the floor body.

[0008] Preferably, a first lamp holder is fixedly connected to the inner front wall and inner rear wall of the bottom box of the first curing box, and a first curing lamp for photocuring the coating film on the lower wall and side wall of the floor body is fixedly connected to the upper wall of the first lamp holder; a second lamp holder is fixedly connected to the inner wall of the upper box of the first curing box, and a second curing lamp for photocuring the coating film on the upper wall of the floor body is fixedly connected to the lower wall of the second lamp holder.

[0009] Preferably, a third bracket is fixedly connected to the inner wall of the bottom box of the second coating box, and a second lower nozzle for spraying the area outside the contact between the lower wall of the floor body and the second conveying roller is fixedly connected to the upper wall of the third bracket; a fourth bracket is fixedly connected to the inner wall of the upper box of the second coating box, and a second side nozzle for spraying the area outside the contact between the side wall of the floor body and the second side positioning wheel is fixedly connected to the lower wall of the fourth bracket.

[0010] Preferably, a third lamp holder is fixedly connected to the inner wall of the bottom chamber of the second curing box, and a third curing lamp for photocuring the coating film on the lower wall of the floor body is fixedly connected to the upper wall of the third lamp holder; a fourth lamp holder is fixedly connected to the inner wall of the upper chamber of the second curing box, and a fourth curing lamp for photocuring the coating film on the side wall of the floor body is fixedly connected to the lower wall of the fourth lamp holder.

[0011] Preferably, the spray paths of the first lower nozzle, the first side nozzle, and the upper nozzle do not interfere with each other, and together they cover the upper surface, the upper half of the side surface, and the middle area of ​​the lower surface of the floor body.

[0014] Preferably, the multiple sets of first transmission shafts and the multiple sets of second transmission shafts are all driven to rotate synchronously by a driving device.

[0015] A moisture-proof coated flooring is provided, which is coated using the aforementioned moisture-proof coated flooring coating device. The flooring body comprises a substrate and a coating film applied to the outer wall of the substrate. The coating film completely covers the upper surface, all side surfaces, and the lower surface of the substrate. The coating film is a nano-hydrophobic coating formed by ultraviolet light curing.

[0016] This invention provides a moisture-proof coated flooring and a coating device. It has the following beneficial effects: 1. Compared with existing technologies, this moisture-proof coated flooring coating device creatively breaks down the traditional one-stop coating process into a "relay" step-by-step processing flow targeting different surface areas of the flooring. This is achieved by sequentially setting up and linking a first coating box, a first curing box, a second coating box, and a second curing box along the conveying direction. In the first processing stage, the device uses a centrally supported conveyor roller with high-positioned side positioning wheels to simultaneously spray and cure the upper surface, upper half of the sides, and middle of the lower surface of the flooring. Then, in the second processing stage, it switches to a two-sided supported conveyor roller with low-positioned side positioning wheels to precisely spray and cure the lower half of the sides and both sides of the lower surface, areas outside the cured area. This zoned, time-segmented design with dynamically adjusted support and positioning strategies fundamentally solves the technical problem of adhesion, contamination, and interference between the uncured coating and the conveying and positioning mechanisms when applying liquid coatings to the bottom and sides of the flooring. This ensures that the coating on all six sides can be formed independently, completely, and with high quality, thus achieving truly comprehensive, all-around, moisture-proof coating for the flooring in a continuous industrial production process.

[0017] 2. Compared to existing technologies, this moisture-proof coated flooring features a continuous and complete nano-hydrophobic coating covering the entire upper surface, all side surfaces, and the lower surface of its substrate, forming a seamless three-dimensional waterproof barrier. Manufactured using a unique process with a specialized coating device, the coating exhibits microscopic bonding characteristics formed by two precise, zoned spraying and curing processes in both the side thickness direction and the lower surface width direction. This structural feature effectively blocks the penetration of liquid water and moisture from any direction in the bathroom environment, completely overcoming the fatal flaw of traditional flooring that is only waterproof on the surface while the edges, locking mechanism, and bottom are susceptible to moisture and erosion. This results in superior and durable overall moisture-proof performance, truly meeting the long-term use requirements of high-humidity environments. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: like Figures 1 to 5 As shown, this embodiment of the invention provides a moisture-proof coated floor and a coating device.

[0022] To achieve zoned, time-based, and precise positioning of the six-sided lamination process for flooring, and to avoid interference and contamination between different processes, this embodiment provides a continuous four-box linkage device. The device consists of a first lamination box, a first curing box, a second lamination box, and a second curing box arranged sequentially along the board conveying direction. Each of the first lamination box, first curing box, second lamination box, and second curing box comprises a bottom box 1, a frame 2, and an upper box 3 arranged vertically. The channels between the boxes are interconnected to allow continuous board passage. Multiple sets of first conveyor shafts 401 arranged sequentially front-to-back are rotatably connected to the inner walls of the frame 2 of the first lamination box and the first curing box. Similarly, multiple sets of second conveyor shafts 402 arranged sequentially front-to-back are rotatably connected to the inner walls of the frame 2 of the second lamination box and the second curing box. All sets of first conveyor shafts 401 and multiple sets of second conveyor shafts 402 are driven synchronously by a drive device to ensure smooth and synchronous board transport between the boxes. The above structure breaks down the complex six-sided processing into four distinct and sequentially connected independent sections, providing a physical basis for the implementation of subsequent zoning, staggered support, and spray curing processes.

[0023] To simultaneously spray the upper surface, upper half of the sides, and middle of the lower surface of the sheet material in the first processing stage, and to ensure the stable posture and precise positioning of the sheet material during the spraying process, this embodiment features a special design for the internal structure of the first coating box and the first curing box. Multiple sets of first conveyor shafts 401 are fitted with first conveyor rollers 5 on their outer walls. The axial length of the first conveyor rollers 5 is configured to be half the width of the sheet material being processed in the left-right direction, and their installation position is configured to be centered in the left-right direction of the sheet material's top-view projection. Multiple sets of first side positioning wheels 6 are rotatably connected to the inner left and right walls of the upper chamber 3 of the first coating box and the first curing box. The horizontal height of the first side positioning wheels 6 is configured so that their supporting surfaces are located above the center of the thickness of the sheet material being processed, i.e., supporting the upper part of the sheet material's sidewalls. When the sheet material is driven forward by the first conveyor shafts 401, the middle area of ​​its lower surface is supported by the first conveyor rollers 5, while the sides are suspended in the air; its left and right sidewalls are clamped from above by the first side positioning wheels 6. Through the above structure, the sheet material obtains joint positioning from the bottom center support and the side high clamp during the conveying process, which effectively prevents horizontal movement and tilting. At the same time, it provides sufficient and stable operating space for the first lower nozzle 8 to accurately spray the middle area of ​​the lower surface and the first side nozzle 9 to spray the upper half area of ​​the side surface, avoiding contact and contamination between the spraying area and the support positioning component.

[0024] To efficiently and accurately complete the simultaneous spraying of the upper surface, upper half of the side surface, and middle of the lower surface of the board in the first processing stage, this embodiment sets up a corresponding spraying system inside the first laminating box. The inner front wall and inner rear wall of the bottom box 1 of the first laminating box are both fixedly connected to a first bracket 7. The upper wall of the first bracket 7 is fixedly connected to a first lower nozzle 8 for spraying the area of ​​the lower wall of the flooring body 12 outside the contact with the first conveyor roller 5, and a first side nozzle 9 for spraying the area of ​​the side wall of the flooring body 12 outside the contact with the first side positioning wheel 6. The inner wall of the upper box 3 of the first laminating box is fixedly connected to a second bracket 10. The lower wall of the second bracket 10 is fixedly connected to an upper nozzle 11 for spraying the upper wall of the flooring body 12. The spray paths of the first lower nozzle 8, the first side nozzle 9, and the upper nozzle 11 are precisely calculated and adjusted to ensure that they do not interfere with each other and together cover the upper surface, the upper half of the side surface, and the middle area of ​​the lower surface of the flooring body 12. When the board passes through the first coating box, the upper nozzle 11, the first side nozzle 9, and the first lower nozzle 8 are activated simultaneously. Through the above structure, the initial application of coating material to the three main large areas of the board's upper surface, upper half of the side surface, and middle of the lower surface can be completed in one pass, which greatly improves the initial coating efficiency and creates conditions for subsequent step-by-step curing.

[0025] To selectively and rapidly cure the coating applied in the first treatment stage, forming a "safe zone" that can support subsequent processes, while avoiding impact on uncoated areas, this embodiment employs a zoned curing system within the first curing chamber. A first lamp holder 13 is fixedly connected to the inner front and inner rear walls of the bottom chamber 1 of the first curing chamber. A first curing lamp 14 for photocuring the coating film on the lower and side walls of the flooring body 12 is fixedly connected to the upper wall of the first lamp holder 13. A second lamp holder 15 is fixedly connected to the inner wall of the upper chamber 3 of the first curing chamber. A second curing lamp 16 for photocuring the coating film on the upper wall of the flooring body 12 is fixedly connected to the lower wall of the second lamp holder 15. When the board material that has completed the first stage of spraying enters the first curing chamber, the second curing lamp 16 cures the coating on its upper surface, while the first curing lamp 14 cures the coating on the middle of the lower surface and the upper half of the side surface. Through this structure, ultraviolet light curing technology rapidly cures the sprayed areas, resulting in a cured coating with sufficient mechanical strength on the upper surface, the upper half of the side surface, and the middle of the lower surface of the board material. These cured areas will serve as the support and clamping contact surfaces between the second conveying roller 17 and the second side positioning wheel 18 in the subsequent second processing stage, thereby completely solving the technical problem of adhesion between the liquid coating and the conveying and positioning mechanism.

[0026] To perform touch-up spraying on the remaining untreated surfaces of the board (i.e., the lower half of the side surface and both sides of the lower surface) in the second processing stage, and to ensure that the support positioning points are located in the cured "safe zone," this embodiment has correspondingly designed the internal structures of the second coating box and the second curing box. Two sections of second conveyor rollers 17 are fitted onto the outer walls of multiple sets of second conveyor shafts 402. The total axial length of the two sections of second conveyor rollers 17 is configured to be less than half the width of the board being processed in the left-right direction, and their installation positions are configured to be close to the left and right side walls of the board being processed, respectively. Multiple sets of second side positioning wheels 18 are rotatably connected to the inner left and right walls of the upper chamber 3 of the second coating box and the second curing box. The horizontal height of the second side positioning wheels 18 is configured so that their supporting surfaces are located below the center of the thickness of the board being processed, i.e., supporting the lower part of the side wall of the board. When the board moves from the first curing chamber into the second coating chamber, the support point on its lower surface changes from the centrally located first conveyor roller 5 to the second conveyor rollers 17 located on both sides, with the contact area being the already cured coating in the middle of the lower surface. Similarly, the clamping point on its side changes from the higher-positioned first side positioning wheel 6 to the lower-positioned first side positioning wheel 18, with the contact area being the already cured coating on the upper half of the side surface. Through this structure, the support and positioning in the second processing stage are entirely based on the cured coating, perfectly exposing the lower half of the side surface and the areas on both sides of the lower surface that require re-spraying. This achieves a precise re-alignment between the support positioning and the spraying area, ensuring the smooth progress of the secondary spraying without any risk of contamination.

[0027] To achieve precise touch-up spraying of the lower half of the side surface of the board and the areas on both sides of the lower surface, this embodiment includes a second spraying system inside the second coating box. A third bracket 19 is fixedly connected to the inner wall of the bottom box 1 of the second coating box. A second lower nozzle 20 is fixedly connected to the upper wall of the third bracket 19 for spraying the area outside the contact between the lower wall of the flooring body 12 and the second conveying roller 17. A fourth bracket 21 is fixedly connected to the inner wall of the upper box 3 of the second coating box. A second side nozzle 22 is fixedly connected to the lower wall of the fourth bracket 21 for spraying the area outside the contact between the side wall of the flooring body 12 and the second side positioning wheel 18. The spray paths of the second lower nozzle 20 and the second side nozzle 22 do not interfere with each other and together cover the lower half of the side surface of the flooring body 12 and the areas on both sides of the lower surface. When the board passes through the second coating box with the support of the second conveying and positioning system, the second side nozzle 22 sprays the lower half of the side surface, and the second lower nozzle 20 sprays the areas on both sides of the lower surface. The above structure completes the coating coverage of all remaining exposed surfaces of the board, achieving full application of the coating on all six sides, and the entire touch-up spraying process does not damage the cured coating.

[0028] To ensure the final curing of the coating applied in the second processing stage, thus completing the entire six-sided coating process, this embodiment incorporates a final curing system within the second curing chamber. A third lamp holder 23 is fixedly connected to the inner wall of the bottom chamber 1 of the second curing chamber, and a third curing lamp 24 for photocuring the coating on the lower wall of the flooring body 12 is fixedly connected to the upper wall of the third lamp holder 23. A fourth lamp holder 25 is fixedly connected to the inner wall of the upper chamber 3 of the second curing chamber, and a fourth curing lamp 26 for photocuring the coating on the side walls of the flooring body 12 is fixedly connected to the lower wall of the fourth lamp holder 25. When the re-sprayed board enters the second curing chamber, the third curing lamp 24 cures the newly sprayed coating on both sides of the lower surface, and the fourth curing lamp 26 cures the newly sprayed coating on the lower half of the side surface. This structure ensures that all coatings, whether applied in the first or second stage, are fully cured, ultimately forming a complete, continuous, and robust waterproof coating layer on the board surface.

[0029] To protect the delicate coating on the sides of the sheet metal and improve positioning stability and cushioning effect, this embodiment optimizes key positioning components. The surfaces of both the first side positioning wheel 6 and the second side positioning wheel 18 are covered with an elastic material, such as rubber or polyurethane. When the first side positioning wheel 6 and the second side positioning wheel 18 clamp the sides of the sheet metal, the elastic coating provides flexible contact pressure through the aforementioned structure. This effectively restrains the sheet metal from shifting and prevents the hard wheel surfaces from scratching or indenting the cured or uncured delicate coating, thus improving production yield and product appearance quality.

[0030] like Figure 6As shown, this embodiment also provides a moisture-proof coated flooring produced by the above-described apparatus and method. The flooring includes a flooring body 12, which consists of a substrate 1201 and a coating film 1202 covering the outer wall of the substrate 1201. The coating film 1202 completely covers the upper surface, all side surfaces, and the lower surface of the substrate 1201, forming a seamless three-dimensional waterproof barrier. The coating film 1202 is a nano-hydrophobic coating formed by the ultraviolet curing process in the aforementioned apparatus. Through this structure, the flooring product achieves all-around protection of the substrate on all six sides. Its coating exhibits microscopic bonding characteristics formed by two precise partitioned spraying and curing processes in the side thickness direction and the lower surface width direction, enabling it to effectively resist the penetration of water vapor and liquid water from any direction in high-humidity environments such as bathrooms, possessing excellent and durable overall moisture-proof performance.

[0031] Working principle: The working principle of this invention is based on the core strategy of "zonal processing, dynamic positioning, and time-sharing curing". The entire system breaks down the traditionally difficult problem of six-sided coating into two logically rigorous processing stages, and achieves continuous production through a four-box linkage device.

[0032] In the first stage (first coating box and first curing box), the device uses a combined positioning method of "central bottom support" and "high-position side clamping" to transport the sheet material and simultaneously spray it on its upper surface, upper half of the side surface, and middle of the lower surface. Then, the coating on these three surfaces is immediately cured with ultraviolet light. The key to this stage is that the cured coating creates a "safe contact zone" that does not adhere to the liquid material in the next stage.

[0033] In the second stage (second coating chamber and second curing chamber), the device's support and positioning mode dynamically switches to "bottom support on both sides" and "low-position side clamping," with the support and clamping points precisely positioned on the coating area that has been cured in the first stage. Under this stable new posture, the device performs additional spraying on the remaining lower half of the side surface and the areas on both sides of the lower surface, and then cures it again.

[0034] Through the ingenious switching and coordination of two-stage support and positioning strategies, the system ensures that when spraying any surface, the corresponding support and positioning components always act on the cured or un-sprayed area, thus eradicating the industry-wide problem of liquid coatings adhering to the transport mechanism. Finally, all coatings are sequentially cured, forming a complete, continuous, and firmly adhered six-sided nano-hydrophobic film layer on the board surface, giving the flooring excellent overall moisture resistance. The entire process is completed automatically in continuous conveying, achieving efficient and high-quality production.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
