Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, and in particular relates to a coating knife roller for coated fabrics. Background Technology

[0002] In the production and processing of coated fabrics, the coating roller is one of the key pieces of equipment. Its function is to uniformly coat the slurry onto the fabric substrate and precisely control the thickness and consistency of the coating. The common method is to configure an independent scraper device on the coating roller system. The scraper is usually fastened to a specific blade holder by multiple bolts. Its cutting edge maintains a precise relative position with the roller surface or the material passage gap to scrape off excess slurry, thereby forming a smooth and uniform coating.

[0003] When applying sizing to fabric, the existing coating rollers rely on the scraper blade, a vulnerable component that directly contacts the sizing. Under prolonged friction from the fabric substrate and the scouring effect of the sizing, the blade inevitably suffers wear, scratches, and even chipping. Damage to the scraper surface directly leads to malfunction, resulting in stripes, ripples, or uneven thickness in the scraped sizing layer. This severely impacts the final fabric processing quality and appearance, necessitating replacement of the separately installed scraper blade. However, the existing bolt-fixing method is extremely inconvenient, requiring maintenance personnel to stop the machine and use tools to disassemble each bolt individually to remove the old scraper blade, thus reducing fabric processing efficiency.

[0004] To address this issue, we provide a coating roller for coated fabrics. Utility Model Content

[0005] The purpose of this invention is to provide a coating blade roller for coated fabrics. By cooperating with the replacement mechanism and the quick-release mechanism, the problem that the replacement of the scraper blade in the existing coating blade roller can easily reduce the fabric production efficiency is solved.

The trough 1 is used to store the slurry used in the coating fabric processing, ensuring that the slurry is evenly supplied between the scraper 2 and the fabric, forming a stable coating supply system. The scraper 2, as the component that directly contacts the slurry, is used to scrape off excess slurry from the fabric surface, controlling the coating thickness and uniformity. The switching mechanism 3 realizes the switching of the scraper 2, improving the continuous operation efficiency of the equipment. The connecting frame 31 supports the entire switching mechanism 3 and connects the trough 1 and the mounting plate 32. Mounting plate 32 is used to install scraper 2 and its related components. Existing external reinforcement mechanisms can also be installed on mounting plate 32 to limit and fix the second gear 333 after it rotates, ensuring the stability of the overall rotation after adjustment. Quick-release mechanism 4 enables quick disassembly and installation of scraper 2, reducing maintenance time and improving production efficiency. Fixing plate 41 serves as the mounting base for quick-release mechanism 4. Positioning groove 42 is used to position the positioning plate 44 of scraper 2, ensuring the accurate installation position of scraper 2. Groove 43 accommodates limiting component 48 and provides installation space for spring 481 and movable plate 482. Positioning plate 44 cooperates with positioning groove 42 to achieve initial positioning of scraper 2. Limiting bracket 45 cooperates with slot 47 through insert rod 46 to lock positioning plate 44 and prevent scraper 2 from loosening during use. Example

[0028] Please see Figures 1-5Based on embodiment 1, the drive assembly 33 includes a motor 331 disposed on one side of the connecting frame 31, a first gear 332 fixedly connected to the output end of the motor 331, and a second gear 333 meshing on one side of the first gear 332. The limiting assembly 48 includes a spring 481 fixedly connected to one side of the groove 43, a movable plate 482 fixedly connected to one side of the spring 481, a limiting plate 483 fixedly connected to one side of the movable plate 482, a limiting groove 484 opened on the limiting frame 45 near the groove 43, a sliding groove 5 provided on one side of the movable plate 482, a slider 6 slidably connected inside the sliding groove 5, the material trough 1 and the scraper 2 are in close contact, the scraping end of the scraper 2 is located outside the material trough 1, the size of the positioning groove 42 is adapted to the positioning plate 44, the size of the slot 47 is adapted to the insertion rod 46, the insertion end of the insertion rod 46 is located in the slot 47 inside the positioning groove 42, and the positioning plate 44 is limited by the cooperation of the insertion rod 46 and the slot 47.

[0029] As a preferred embodiment of the above: the motor 331 is fixedly connected to the mounting plate 32, the second gear 333 is fixedly connected to the surface of the connecting frame 31, the gear ratio of the second gear 333 to the first gear 332 is 2:1, the limiting plate 483 extends from the side of the limiting frame 45 to the side of the fixed plate 41 near the limiting frame 45, the size of the limiting groove 484 is adapted to the limiting plate 483, the sliding groove 5 is opened inside the groove 43 on one side, the size of the sliding groove 5 is adapted to the slider 6, the slider 6 is fixedly connected to the movable plate 482, the driving component 33 provides power to control the rotation of the mounting plate 32, realize the quick replacement of the scraper 2, and the limiting component 48 is used to lock the limiting frame 45 to prevent it from accidentally disengaging during operation.

[0030] The working principle of this utility model is as follows: During use, the slurry is stored in the material tank 1 and evenly coated onto the fabric surface through the gap between the scraper 2 and the fabric. The scraper 2 removes excess slurry, forming a smooth coating. When the scraper 2 needs to be replaced due to wear or damage, the motor 331 in the drive assembly 33 is started, driving the first gear 332 and the second gear 333 to rotate, thereby causing the mounting plate 32 and the scraper 2 on it to rotate half a turn, switching the spare scraper 2 to the working position, realizing non-stop scraper replacement, ensuring continuous production, and replacing the scraper 2. When installing a new scraper 2, press the limiting plate 483 to disengage it from the limiting groove 484 on the limiting frame 45, pull the limiting frame 45 to remove the insertion rod 46 from the slot 47, and release the limiting of the positioning plate 44. The old scraper 2 can then be removed. When installing a new scraper 2, insert the positioning plate 44 into the positioning groove 42, push the limiting frame 45 to insert the insertion rod 46 into the slot 47, and the spring 481 pushes the movable plate 482 to make the limiting plate 483 snap into the limiting groove 484, thus completing the quick fixing of the scraper 2. The whole process does not require tools, is easy to operate, and greatly improves maintenance efficiency.
