Description

Technical Field

[0001] This invention relates to the field of flooring manufacturing technology, and in particular to a nano-172 excimer skin-feel flooring processing system and its processing method. Background Technology

[0002] As consumers continue to demand higher quality home decoration, skin-feel flooring, with its delicate and smooth touch, excellent appearance and texture, and good stain resistance, has gradually become one of the mainstream products in the market.

[0003] However, the processing systems and equipment used in existing processing technologies are relatively simple. They usually just connect the equipment of each process, resulting in poor overall connectivity. Problems can easily occur with the boards during the connection and transportation process, which can affect the quality. Moreover, the topcoat coating equipment in the existing processing system is relatively conventional. The height of the coating roller is adjusted manually, which makes it impossible to adjust the distance between the roller and the board precisely. Furthermore, the manual adjustment method is prone to errors due to human factors, resulting in a distance that is too large or too small, which affects the coating effect. Moreover, existing topcoat coating equipment uses single-roller coating, which can easily lead to uneven topcoat application during the coating process, affecting subsequent quality. Summary of the Invention

[0004] The purpose of this invention is to provide a nano-172 excimer skin-feel flooring processing system and method. This invention has the advantages of being more convenient to use and producing relatively better processing quality.

[0008] In the aforementioned nano-172 excimer skin-feel flooring processing system, the topcoat coating unit includes a coating chamber, a board conveyor belt located at the bottom of the coating chamber, and a coating structure that can be raised and lowered and adjusted within the coating chamber. There are two coating structures, which are horizontally distributed at the front and rear ends of the coating chamber. Each coating structure includes a fixed frame located above, a lifting frame located below the fixed frame that can be raised and lowered, a lifting module located on the fixed frame and driving the lifting frame to rise and fall, and coating rollers that can be detachably located at the front and rear ends of the lifting frame.

[0011] A method for processing nano-172 excimer skin-feel flooring includes the following steps: S1. Feeding and surface cleaning: The substrate is conveyed to the surface cleaning unit, where it passes through a brush pre-cleaning module to remove surface dust and impurities, a high-pressure air blowing module to blow away fine particles, and finally a nano-level dust suction module to remove residual impurities. S2, Primer application and first drying and curing: After cleaning, the substrate enters the primer coating unit, where a combination of roller coating and doctor blade coating is used to apply the nano-modified primer; after coating, it is sent to the first drying and curing unit for curing. S3, Precision Sanding: The cured substrate is then transported to a precision sanding unit for sanding. S4. Topcoat application and LED pre-curing: After sanding, the substrate enters the topcoat coating unit and is coated with a special topcoat for nano-172 excimer laser using a roller coating method. After coating, it is sent to the LED pre-curing unit to allow the topcoat surface to be initially cured. S5, Nano 172 excimer laser irradiation modification: The substrate, after being pre-cured by LEDs, enters the nano-172 excimer irradiation unit, where the topcoat surface is formed by high-energy irradiation with 172nm excimer lamps. S6, Second drying and curing: The substrate irradiated by the excimer laser is then sent to the second drying and curing unit for final curing. S7. Detect the discharged material: After curing, the products are inspected by the quality inspection unit. Qualified products are output through the discharge conveyor unit, while unqualified products are reworked.

[0012] In the aforementioned processing method for nano-172 excimer skin-feel flooring, the feeding and surface cleaning described in S1 are as follows: S1.1, Feeding Pre-treatment: The substrate is conveyed to the temporary storage area through the feeding conveyor unit. The moisture content of the substrate is tested by a moisture content detector. Qualified substrates enter the next process, and unqualified substrates are subjected to moisture conditioning treatment. S1.2 Brush pre-cleaning: The qualified substrate is conveyed to the brush pre-cleaning module of the surface cleaning unit. The soft nylon brush is in close contact with the substrate surface and cleans it twice along the length of the substrate to remove floating dust and larger impurities from the substrate surface. S1.3 High-pressure air blowing: The pre-cleaned substrate enters the high-pressure air blowing module, and fine particles on the surface of the substrate are blown away using an air nozzle at a pressure of 0.3-0.5MPa. S1.4 Nanoscale dust collection: The substrate after air blowing enters the nanoscale dust collection module, and residual impurities are removed by negative pressure through the dust collection port; S1.5 Cleaning Inspection: The surface of the substrate is inspected using a surface cleanliness tester. If it passes the test, it proceeds to the next process; otherwise, it is returned to the brush pre-cleaning unit for reprocessing.

[0013] In the aforementioned nano-172 excimer skin-feel flooring processing method, the topcoat coating and LED pre-curing described in S4 are as follows: S4.1 Topcoat Pretreatment: Pour the nano 172 excimer special topcoat into the material tank of the topcoat coating unit, stir evenly, and then keep it at a constant temperature. S4.2 Topcoat Coating: The sanded substrate enters the coating chamber 1 of the topcoat coating unit. The lifting motor drives the lifting frame to rise and fall, which in turn drives the coating roller to rise and fall. The coating roller contacts the surface of the substrate to perform roller coating. S4.3 Initial inspection after coating: Inspect the thickness of the topcoat coating; if the error exceeds the specified substrate thickness, corrective treatment shall be carried out. S4.4, LED Pre-curing: Substrate that has passed the initial inspection is sent to the LED pre-curing unit, where LED lights are used to irradiate it with a certain power. During the pre-curing process, the substrate is transported at a constant speed. S4.5 Pre-curing test: Use a curing degree tester to test the curing degree of the topcoat. If it fails, adjust the LED power or irradiation time and re-pre-cur it.

[0014] Compared with the prior art, this application has the following beneficial effects: 1) This invention uses a 172nm excimer lamp for irradiation modification. Its wavelength is shorter and its energy is higher, which can form a uniform nanoscale uneven structure on the surface of the topcoat, significantly improving the skin texture and smoothness of the floor compared to existing products. At the same time, 172nm excimer irradiation can promote the uniform dispersion of nanoparticles in the topcoat, significantly improving the wear resistance and scratch resistance of the floor. 2) The processing system adopts a fully integrated design. Each unit works in concert through the central control system, realizing automatic feeding, continuous processing and precise parameter control of the substrate, reducing manual intervention, and resulting in higher processing efficiency and more stable product quality. 3) The structure of the topcoat coating unit has been optimized. It has two adjustable coating structures, which are distributed in front and behind. Each coating structure is equipped with a lifting motor, a lifting screw and a lifting frame. The coating rollers are distributed at both ends of the lifting frame, and multiple distance sensors are set under the lifting frame. The distance sensors monitor the distance to the substrate surface in real time, thereby driving the lifting motor to precisely adjust the distance between the coating rollers and the substrate surface, resulting in better and more uniform coating effect. Therefore, the present invention has the advantages of being more convenient to use and having relatively better processing quality. Attached Figure Description

Topcoat application and LED pre-curing: After sanding, the substrate enters the topcoat coating unit and is coated with a special topcoat for nano-172 excimer laser using a roller coating method. After coating, it is sent to the LED pre-curing unit to allow the topcoat surface to be initially cured. S5, Nano 172 excimer laser irradiation modification: The substrate, after being pre-cured by LEDs, enters the nano-172 excimer irradiation unit, where the topcoat surface is formed by high-energy irradiation with 172nm excimer lamps. S6, Second drying and curing: The substrate irradiated by the excimer laser is then sent to the second drying and curing unit for final curing. S7. Detect the discharged material: After curing, the products are inspected by the quality inspection unit. Qualified products are output through the discharge conveyor unit, while unqualified products are reworked.

[0025] The feeding and surface cleaning described in S1 are as follows: S1.1, Feeding Pre-treatment: The substrate is conveyed to the temporary storage area through the feeding conveyor unit. The moisture content of the substrate is tested by a moisture content detector. Qualified substrates enter the next process, and unqualified substrates are subjected to moisture conditioning treatment. S1.2 Brush pre-cleaning: Qualified substrates are conveyed to the brush pre-cleaning module of the surface cleaning unit. A soft nylon brush with a rotation speed of 150-200 r / min is used to contact the substrate surface and clean it twice along the length of the substrate to remove floating dust and larger impurities from the substrate surface. S1.3 High-pressure air blowing: After pre-cleaning, the substrate enters the high-pressure air blowing module. Fine particles on the surface of the substrate are blown away with an air nozzle set at an angle of 45° at a pressure of 0.3-0.5MPa. The distance between the air nozzle and the surface of the substrate is 10-15mm, and the air blowing speed is matched with the substrate conveying speed. S1.4 Nanoscale dust collection: After being blown by air, the substrate enters the nanoscale dust collection module, where residual impurities are removed by negative pressure (-0.08 to -0.06 MPa) at the dust collection port. The distance between the dust collection port and the substrate surface is 5-8 mm. S1.5 Cleaning Inspection: The surface of the substrate is inspected using a surface cleanliness tester. If it passes the test, it proceeds to the next process; otherwise, it is returned to the brush pre-cleaning unit for reprocessing.

[0026] The specific details of the primer coating and first drying and curing process described in S2 are as follows: S2.1 Primer pretreatment: Pour the nano-modified primer into the material tank of the primer coating unit and stir evenly; S2.2 Primer Coating: The cleaned substrate enters the primer coating unit and is coated using a combination of roller coating and doctor blade. The coating roller speed is 50-80 r / min, and the gap between the doctor blade and the coating roller is adjusted to 80-100 μm. The coating environment is controlled at humidity 40%-60% and temperature 20-25℃ to ensure that the primer coating thickness is 80-100 μm. S2.3 Initial inspection after coating: The thickness of the primer coating is tested using a coating thickness tester. Substrates with a thickness error exceeding ±5μm are recoated or scraped off and recoated. S2.4 First Drying and Curing: The substrate that passes the initial inspection is sent to the first drying and curing unit (i.e., hot air circulating curing chamber). It is first dried in a high temperature section of 60-70℃ for 10-12 minutes (hot air velocity 1.5-2m / s), and then cured in a low temperature section of 40-50℃ for 5-8 minutes (hot air velocity 1-1.5m / s). During the curing process, the temperature inside the chamber is monitored in real time by a temperature sensor to ensure that the primer curing degree reaches 85%-90%. S2.5 Post-curing inspection: The curing degree of the primer is tested using a curing degree tester. If it passes the test, it proceeds to the next process. If it fails the test, the curing parameters are adjusted and the primer is cured again.

The sander conveying speed is adjusted to 0.3-0.6m / min. The tension of the 400-mesh, 600-mesh, and 800-mesh sanding belts is checked and adjusted to 0.8-1.2MPa. S3.2, Graded Sanding: The substrate passes through a three-roller sanding structure in sequence. The first roller uses a 400-mesh sanding belt with a sanding pressure of 0.2-0.3MPa to coarsely sand the substrate and remove the protrusions on the primer surface. The second roller uses a 600-mesh sanding belt with a sanding pressure of 0.15-0.25 MPa to perform medium sanding and refine the surface roughness; The third roller uses an 800-mesh sanding belt with a sanding pressure of 0.1-0.2 MPa to fine sand the surface and improve its smoothness. The sanding depth is controlled within 5-10μm throughout the process and is corrected in real time using a depth adjustment device. S3.3 Dust removal after sanding: The sanded substrate is then vacuumed by a negative pressure dust collection device at a negative pressure of -0.07 to -0.05 MPa to remove surface dust and ensure that no residual particles remain. S3.4 Smoothness Inspection: The surface of the primer is inspected using a surface roughness tester and a smoothness tester.

S4.3 Initial inspection after coating: Inspect the thickness of the topcoat coating. Substrates with an error exceeding ±3μm shall be corrected. S4.4, LED Pre-curing: Substrate that has passed the initial inspection is sent to the LED pre-curing unit. LED lamps with a wavelength of 365nm are used. The distance between the lamps and the surface of the substrate is 20-30mm. The substrate is irradiated with a certain power of 800-1000W for 3-5 seconds. During the pre-curing process, the substrate is kept in a nitrogen protection environment while maintaining a uniform conveying speed of 0.4-0.8m / min to ensure uniform irradiation. S4.5 Pre-curing test: Use a curing degree tester to test the curing degree of the topcoat. If it fails, adjust the LED power or irradiation time and re-pre-cur it.

[0029] The specific details of the nano-172 excimer irradiation modification described in S5 are as follows: S5.1 Preparation before irradiation: The substrate that has been pre-cured by LED is transported to the nano 172 excimer irradiation unit. The distance between the 172nm excimer lamp group and the substrate surface is adjusted to 5-15mm through the distance adjustment module. The purity of nitrogen in the inert gas protection module is checked. S5.2 Inert gas protection: Turn on the nitrogen delivery device, control the nitrogen flow rate to 5-10L / min, and continuously supply nitrogen to the irradiation area. After the oxygen content detector shows that the oxygen content in the area is ≤0.5%, continue to supply nitrogen. S5.3 Excimer Irradiation: Activate the excimer lamp assembly and irradiate the substrate surface with a power of 1200-1500W for 2-4 seconds. The substrate conveying speed should be matched with the irradiation time, at 0.3-0.5m / min, to ensure uniform irradiation of the surface. S5.4 Cooling after irradiation: The irradiated substrate enters the cooling zone and is cooled to room temperature by natural wind.

[0030] The second drying and curing process described in S6 is as follows: S6.1 Second Drying and Curing: The cooled substrate is sent into the second drying and curing unit. The indoor temperature is first raised to 35-45℃ at a heating rate of 5℃ / min, while the humidity is adjusted to 30%-40%. This environment is maintained for curing for 25-30 minutes. The temperature and humidity are recorded every 5 minutes during the curing process. If the deviation exceeds ±2℃ or ±5%, it is corrected in time. S6.2 Cooling after curing: The cured substrate is sent to a cooling chamber and a gradient cooling method is used.
