Description

Technical Field

[0001] This invention relates to the field of specialty paper manufacturing technology, and in particular to a production equipment and process for producing anti-deformation sulfuric acid paper. Background Technology

[0002] Due to its translucent, tough, and smooth surface, tracing paper is used in high-end printing, packaging, handicrafts, and engineering drawing. However, because its main component is natural cellulose, it has strong hydrophilicity and will absorb moisture from the air, causing it to swell and deform, and in severe cases, even become unusable.

[0003] In existing technologies, the main solution to the problem of paper getting damp relies on controlling the ambient humidity, which is a passive and costly method. Once the paper leaves the controlled environment, the problem will still occur. Another method is to spray a moisture-proof liquid on the paper surface, but this method will change the paper's transparency, surface smoothness and printability, and its environmental friendliness is questionable.

[0004] In response to the aforementioned technologies, a novel sulfonate paper processing technology and specialized equipment are provided. This technology processes ordinary sulfonate paper to form a robust moisture barrier on its surface and locks in the paper fiber structure through heat-fixing technology, thereby achieving extremely high dimensional stability. It can maintain its shape even in humid environments while retaining its excellent printing and processing performance. Summary of the Invention

[0026] A second aspect of the present invention provides a production process for a production equipment for anti-deformation sulfuric acid paper, comprising the following steps:

[0027] S1. Turn on the internal circulating cooling water system of the printing roller and cooling roller, and confirm that their surface temperature has dropped to room temperature. The equipment has a certain degree of compatibility and can be used for printing with UV ink and water-based ink. If UV ink is used, turn on the UV curing lamp, preheat to the working power, and check that it is intact. If water-based ink is used, confirm that the cooling roller is ready and no additional preheating is required. Finally, according to the thickness and moisture protection requirements of the tracing paper to be produced, select the appropriate line count anilox roller for both sides of the equipment to control the amount of ink coating and ensure the tension balance on both sides.

[0028] S2. Correctly install the roll of ordinary sulfuric acid paper onto the unwinding shaft, and manually pull the paper head through each guide roller, preconditioning station, printing unit, and water-cooled curing station, and finally fix it onto the take-up shaft core. At the same time, inject the prepared water-based ink or UV ink into the ink supply system of the printing unit, start the circulation, and ensure that the liquid is uniform and free of bubbles.

[0029] S3. Start the equipment at low speed using the control controller and observe the paper smoothly entering the pre-conditioning tension control station. The micro humidifier in the pre-conditioning tension control station starts working, slightly adjusting the humidity or temperature of the sulfite paper. Subsequently, the pre-conditioned paper enters the printing unit. The ink in the ink fountain is transferred to the anilox roller by the rotation of the ink guide roller. The outer side of the anilox roller rotates and adheres to the printing roller. The surface of the printing roller is etched with the pattern to be printed. The anilox roller and the printing roller roll against each other under certain pressure, transferring a certain amount of ink from the cells of the anilox roller to the relief pattern on the printing roller. At the same time, the doctor blade located on one side of the printing roller is used to scrape off excess ink from the non-image area of ​​the printing roller. Subsequently, under the pressure of the printing roller, the ink is transferred to the surface of the paper. At the same time, the paper comes into contact with the low-temperature printing roller.

[0030] S4. The printed paper immediately enters the water-cooled curing and tension stabilization station. The printed surface of the paper runs in close contact with the surface polished cooling roller, which is filled with cooling water. If water-based ink is used, the low temperature will accelerate the film-forming and curing process of the ink on the tracing paper. If UV ink is used, the UV curing lamp emits ultraviolet light to cure the ink above the arc section of the paper that wraps around the cooling roller. The low temperature roller quickly absorbs the heat generated by the curing reaction, ensuring that the paper is subjected to extremely stable stress during the curing stage. After passing through the water-cooled curing station, the ink has been completely cured, forming a strong moisture barrier on the surface of the tracing paper.

[0031] S5. The processed anti-deformation tracing paper is moved up and down by the ion air bar through the mechanical mechanism in the tail box to remove the static electricity between the tracing paper. Then, it is wound up flat by the winding unit.

[0032] S6. Gradually reduce the equipment operating speed to low speed, stop ink supply, coolant circulation, pre-conditioning device and UV curing lamp working unit, and stop the equipment completely after the paper is completely removed from the processing area.

[0033] In summary, the present invention has at least one of the following beneficial technical effects:

[0034] 1. This invention uses an anilox roller to evenly coat ink onto the surface of sulfuric acid paper. The internal cooling system of the printing roller maintains a low temperature, provides stable support, and rapidly cools the ink. A UV curing lamp cures the moisture-proof liquid to form a moisture barrier, locking the fiber structure. A tension control structure ensures that the paper runs flat, thereby effectively preventing deformation caused by humidity or thermal stress. This results in products with extremely high dimensional stability and flatness, and clear and full printed patterns.

[0035] 2. This invention uses a UV curing lamp to emit ultraviolet light, causing the moisture-proof liquid or ink to undergo a polymerization reaction and solidify instantly. The cooling roller circulates cooling water through a spiral flow channel, which efficiently absorbs heat. The limiting chamber guides the paper's running path, and the cured paper is discharged from the outlet. This gives the sulfonate paper extremely high dimensional stability, is unaffected by humidity, remains flat and without curling, and has strong environmental adaptability.

[0036] 3. In this invention, the paper is guided into the tail box by the discharge roller. The motor embedded in the groove drives the elliptical gear to rotate the circular gear, which in turn causes the vertical rod to drive the ion air bar to move up and down. The ion air bar releases positive and negative ion beams, which effectively neutralize the static charge on the paper surface. The transmission system adjusts the running rhythm to ensure that the paper is output smoothly in a static-free state. Attached Figure Description

[0060] The production process of the anti-deformation tracing paper production equipment described below can be referred to in correspondence with the anti-deformation tracing paper production equipment described above.

[0061] This invention also provides a production process for a production equipment for anti-deformation sulfuric acid paper, comprising the following steps:

[0062] S1. Turn on the internal circulating cooling water system of the printing roller 314 and cooling roller 404, and confirm that their surface temperature has dropped to room temperature. The equipment has a certain degree of compatibility and can be used for printing with UV ink and water-based ink. If UV ink is used, turn on the UV curing lamp 402, preheat to the working power, and check whether it is intact. If water-based ink is used, confirm that the cooling roller 404 is ready and no additional preheating is required. Finally, according to the thickness and moisture protection requirements of the tracing paper to be produced, select the anilox roller 313 with the appropriate line count for both sides of the equipment to control the amount of ink coating and ensure the tension balance on both sides.

[0063] S2. Correctly install the roll of ordinary sulfuric acid paper onto the unwinding shaft, and manually pull the paper head through each guide roller, preconditioning station, printing unit, and water-cooled curing station, and finally fix it onto the take-up shaft core. At the same time, inject the prepared water-based ink or UV ink into the ink supply system of the printing unit, start the circulation, and ensure that the liquid is uniform and free of bubbles.

[0064] S3. Start the equipment at low speed using the control controller and observe the paper smoothly entering the pre-conditioning tension control station. The micro humidifier 12 of the pre-conditioning tension control station starts working to slightly adjust the humidity or temperature of the sulfite paper. Subsequently, the pre-conditioned paper enters the printing unit. The ink in the ink guide 320 is transferred to the anilox roller 313 by the rotation of the ink guide roller 311. The outer side of the anilox roller 319 rotates and adheres to the printing roller 309. The surface of the printing roller 309 is etched with the pattern to be printed. The anilox roller 319 and the printing roller 309 roll against each other under a certain pressure, transferring a certain amount of ink from the cells of the anilox roller 319 to the relief pattern of the printing roller 309. At the same time, the doctor blade 310 located on one side of the printing roller 319 is used to scrape off excess ink from the non-image area surface of the printing roller 309. Subsequently, under the pressure of the printing roller 314, the ink is transferred to the paper surface. At the same time, the paper comes into contact with the low-temperature printing roller 314.

[0065] S4. The printed paper immediately enters the water-cooled curing and tension stabilization station. The printed surface of the paper runs in close contact with the surface polished cooling roller 404, which is filled with cooling water. If water-based ink is used, the low temperature will accelerate the film-forming and curing process of the ink on the tracing paper. If UV ink is used, the UV curing lamp 402 emits ultraviolet light to cure the ink above the arc section of the paper that wraps around the cooling roller 404. The low temperature roller quickly absorbs the heat generated by the curing reaction, ensuring that the paper is subjected to extremely stable stress during the curing stage. After passing through the water-cooled curing station, the ink has been completely cured, forming a strong moisture barrier on the surface of the tracing paper.

[0066] S5. The processed anti-deformation tracing paper is moved up and down by the ion air bar 504 through the mechanical mechanism in the tail box 501 to remove the static electricity between the tracing paper. Then, it is wound up flat by the winding unit.

[0067] S6. Gradually reduce the equipment operating speed to low speed, stop ink supply, coolant circulation, preconditioning device and UV curing lamp 402 working unit. After the paper is completely removed from the processing area, the equipment will stop completely.

[0068] The production process in this embodiment can be used to execute the production equipment embodiment described above, and its principle and technical effects are similar, so they will not be repeated here.

[0069] Working principle: First, during the printing process, the moisture-proof liquid is evenly applied to the surface of the tracing paper via the anilox roller 313. The cooling system of the printing roller 314 maintains a low temperature, providing stable support for the paper and accelerating ink cooling. The UV curing lamp 402 emits ultraviolet light, causing the moisture-proof liquid to undergo a polymerization reaction and quickly solidify into a tight moisture-proof barrier, thereby locking the paper fiber structure. The tension control structure keeps the paper running flat. The entire process works in synergy, significantly reducing the deformation that may be caused by humidity changes and thermal stress. As a result, the product achieves superior dimensional stability and surface flatness, with clear and full printed patterns, and color retention. The production process is continuous and stable, adapting to various printing needs and improving the overall quality of the finished product.

[0070] Furthermore, during the curing stage, the UV curing lamp 402 emits ultraviolet light, causing the moisture-proof liquid or ink to undergo a polymerization reaction and cure instantly. The cooling roller 404 has a spiral flow channel inside, and the circulating cooling water efficiently absorbs heat. The limiting chamber 401 guides the paper's path, and the discharge port 403 discharges the cured paper. This series of operations enables the sulfonate paper to obtain high dimensional stability, is not affected by environmental humidity, maintains a flat surface without curling, and at the same time, the curing process is energy-efficient, reduces energy consumption, has good environmental adaptability, is suitable for continuous production operations, and enhances product durability and consistency.

[0071] Finally, in the static elimination stage, the paper is guided into the tail box 501 by the discharge roller 505. The motor 508 in the embedded groove 502 drives the elliptical gear 509 to rotate. The elliptical gear 509 meshes with the circular gear 510, transmitting the motion to the vertical rod 511. The vertical rod 511 drives the ion bar 504 to move up and down reciprocally. The ion bar 504 releases positive and negative ion beams, effectively neutralizing the static charge accumulated on the surface of the paper. The transmission system adjusts the operating rhythm to ensure that the paper is output smoothly without static interference, thereby avoiding dust adsorption and paper sticking problems. The winding is neat and smooth, improving the cleanliness of the finished product and production efficiency, and ensuring the smooth progress of subsequent processing steps.

[0072] 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.
