Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric coating scraping structure technology, and in particular to a quantitative scraping device for applying light-blocking coatings to decorative fabrics. Background Technology
[0002] With the development of functional textiles, coated fabrics have been widely used in outdoor sports, medical protection, and military equipment due to their excellent waterproof, oil-proof, and wind-resistant properties. Traditional fabric coating processes typically employ techniques such as scraping, roller coating, and dip coating to uniformly adhere functional coating materials to the fabric surface to achieve the desired properties. However, existing coating processes still have certain limitations in adaptability, making it difficult to dynamically adjust process parameters according to different fabric thicknesses. This results in limited coating uniformity and adhesion, affecting product quality.
[0003] In addition, most coating processing equipment is still mainly intermittent, with poor processing continuity, which cannot meet the needs of modern production for high efficiency and large-volume output. Especially when the types of fabrics are frequently changed or the specifications are greatly different, it is more likely to cause production line stoppages, material waste and reduced production efficiency.
[0004] Therefore, there is an urgent need for a coating processing device that can balance adaptability and processing continuity in order to improve coating quality and overall production efficiency. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a quantitative scraping device for applying light-blocking coatings to decorative fabrics.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution.
[0007] A quantitative scraping device for applying a light-blocking coating to decorative fabrics includes a worktable, a lifting mechanism, and a coating processing mechanism. The lifting mechanism includes a support plate and a pneumatic lifting rod. The lower end of the pneumatic lifting rod is fixed inside the worktable, and the upper end of the pneumatic lifting rod is fixedly connected to the support plate. The coating processing mechanism includes a scraping box and a drying box. Fixing mechanisms are connected to both sides of the scraping box and the drying box to fix them on the worktable.
[0008] Preferably, a feeding box is connected above the coating box, an anilox roller is provided below the coating box, and a coating component is provided on one side of the anilox roller.
[0009] Preferably, the drying box has multiple air boxes on one side, each containing a fan. The drying box has ventilation openings that correspond to the fans, and a filter screen is provided on the outside of the air boxes.
[0010] Preferably, the drying box is equipped with a U-shaped air distribution pipe, with the opening side of the U-shaped air distribution pipe corresponding to the ventilation opening.
[0011] Preferably, the U-shaped air distribution duct has multiple evenly spaced ventilation holes on its curved surface.
[0012] Preferably, the drying box has an opening on the other side, and two downward-sloping baffles are provided at the opening.
[0013] Preferably, multiple drying lamps are fixedly connected to the bottom of the drying box.
[0014] Preferably, the fixing mechanism includes a fixing arm and a fixing base. The fixing base is fixed to both sides of the workbench by bolts. The lower end of the fixing arm is fixedly connected to the fixing base, and the upper ends of the fixing arm are fixedly connected to a scraping box or a drying box.
[0015] This invention, by adopting the above technical solutions, has significant technical advantages: The lifting mechanism, composed of a pneumatic lifting rod and a support plate, allows for flexible adjustment of the positions of the coating box and drying box according to fabric thicknesses, enhancing the device's adaptability to various fabric specifications and preventing uneven coating or coating defects caused by varying thicknesses. The presence of an anilox roller and a coating tool below the coating box allows for precise control of the coating output, while the coating tool further controls the coating thickness, achieving quantitative coating of the light-blocking coating and improving finished product consistency and surface quality. Continuous arrangement enables integrated coating and drying processes, avoiding the interruption required in traditional processes where coating requires transfer to other devices for drying, thus improving processing continuity and overall efficiency.

Detailed Implementation
[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figures 1 to 5 As shown in the illustration, this application provides a quantitative scraping device for applying a light-blocking coating to decorative fabrics. The device includes a worktable 1, a lifting mechanism, and a coating processing mechanism. The lifting mechanism includes a support plate 11 and a pneumatic lifting rod 12. The lower end of the pneumatic lifting rod 12 is fixed inside the worktable 1, and the upper end of the pneumatic lifting rod 12 is fixedly connected to the support plate 11. The coating processing mechanism includes a scraping box 2 and a drying box 3. Fixing mechanisms are connected to both sides of the scraping box 2 and the drying box 3, fixing them to the worktable 1. By setting up the lifting mechanism composed of the pneumatic lifting rod 12 and the support plate 11, the positions of the scraping box 2 and the drying box 3 can be flexibly adjusted according to fabrics of different thicknesses, improving the device's adaptability to various fabric specifications and avoiding uneven scraping or coating defects caused by varying thicknesses. This device fixes the scraping box 2 and the drying box 3 on the same worktable 1 surface and achieves integrated scraping and drying processing through continuous arrangement, avoiding the interruption of traditional processes where scraping requires transfer to other devices for drying, thus improving processing continuity and overall efficiency.
[0024] A feeding box 21 is connected above the coating box 2, and an anilox roller 22 is located below the coating box 2. A coating scraper 23 is located on one side of the anilox roller 22. In this embodiment, by using the anilox roller 22 and the coating scraper 23 located below the coating box 2, the anilox roller 22 can precisely control the amount of coating output, while the coating scraper 23 further controls the coating thickness, thereby achieving quantitative coating of the light-blocking coating and improving the consistency and surface quality of the finished product.
[0025] Multiple air boxes 31 are provided on one side of the drying box 3, and a fan 32 is installed inside the air box 31. Ventilation vents 33 are provided on the drying box 3, and the ventilation vents 33 are arranged corresponding to the fans 32. A filter screen 34 is provided on the outside of the air box 31. By setting up multiple air boxes 31 and fans 32, and combining them with U-shaped air distribution pipes 35 and their evenly distributed ventilation holes 36, uniform circulation of hot air is achieved, improving the drying effect. In addition, the setting of drying lamps 38 further accelerates the curing speed of the coating and reduces the waiting time.
[0026] The drying box 3 is equipped with a U-shaped air distribution pipe 35. The opening side of the U-shaped air distribution pipe 35 corresponds to the ventilation port 33, so that the internal air can circulate and realize the drying operation.
[0027] The U-shaped air distribution duct 35 has multiple evenly spaced ventilation holes 36 on its arc-shaped surface, which makes the internal airflow more uniform and reduces uneven coating thickness during drying due to excessive local airflow intensity.
[0028] The drying box 3 has an opening on the other side, and two downward-sloping guide plates 37 are provided at the opening to direct the airflow generated inside toward the coating and speed up the drying process.
[0029] Multiple drying lamps 38 are fixedly connected to the bottom of the drying box 3, which, in conjunction with the airflow, improve the drying efficiency.
[0030] The fixing mechanism includes a fixing arm 41 and a fixing base 42. The fixing base 42 is fixed to both sides of the workbench 1 by bolts. The lower end of the fixing arm 41 is fixedly connected to the fixing base 42, and the upper end of the fixing arm 41 is fixedly connected to the scraper box 2 or the drying box 3. By setting the fixing mechanism, the scraper box 2 and the drying box 3 can be stably installed and disassembled. The structure is reliable and easy to maintain and replace.
[0031] During use, the lower end of the pneumatic lifting rod 12 is fixed inside the workbench 1, and the upper end is connected to the support plate 11. It is used to drive the support plate 11 to move up and down, thereby adjusting the height of the connecting components on the support plate 11 to adapt to fabrics of different thicknesses.
[0032] The coating processing mechanism includes a scraper box 2 and a drying box 3 arranged sequentially on the working path. Both are securely installed on the worktable 1 by a fixing mechanism (including a fixing arm 41 and a fixing base 42) to ensure stable position during operation.
[0033] During the coating stage, the fabric moves smoothly along the working path to the bottom of the coating box 2. A feeding box 21 containing light-blocking coating is connected above the coating box 2. The coating flows into the surface of the anilox roller 22 inside the coating box 2 by gravity or pumping. The anilox roller 22 rotates at a constant speed, evenly transferring the coating to the fabric surface. A coating component 23 (such as a scraper or rubber plate) is provided on one side to scrape off excess coating and control the coating thickness, achieving quantitative coating of the light-blocking coating.
[0034] The coated fabric continues to enter the drying chamber 3 for drying. Multiple air boxes 31 are located on one side of the drying chamber 3, each containing a built-in fan 32. These fans blow heated air through a U-shaped air distribution duct 35 into the drying area. The curved surface of the U-shaped air distribution duct 35 has multiple ventilation holes 36 to ensure even distribution of hot air to the fabric surface, improving drying efficiency and uniformity. Simultaneously, a downward-sloping guide plate 37 is located on the other side of the drying chamber 3 to guide residual heat and airflow smoothly out, preventing eddy current buildup.
[0035] In addition, multiple drying lamps 38 are installed below the drying box 3 to further accelerate the drying speed of the light-blocking coating.
[0036] In summary, the device in this embodiment achieves precise quantitative coating while enabling rapid and uniform drying through the combined action of multi-channel hot air and drying lamp 38. Furthermore, the device height can be adjusted via a pneumatic lifting system to accommodate different fabric thicknesses, ensuring processing quality and efficiency, and demonstrating excellent industrial applicability.
