[0001] This utility model relates to the field of ink and coating preparation technology, and in particular to a filtration device for ink and coating preparation. Background Technology

[0002] Ink is an important material used in printing. It displays patterns and text on a substrate through printing. Ink consists of main components and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of binders (resins), pigments, fillers, additives, and solvents, and is used in various printing applications such as books, packaging, architectural decoration, and electronic circuit boards. With the increase in social demand, the variety and output of ink coatings have also expanded and increased accordingly. In the process of ink coating production, filtration devices are needed to remove impurities from the ink coating before proceeding to the next production process.

[0003] Existing ink filtration devices filter ink directly on a filter screen. However, during the filtration process, the filter screen becomes clogged with particulate matter, requiring frequent replacement. This increases operational difficulty and cost, resulting in low ink filtration efficiency and reduced ink processing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology lacks the self-cleaning function of the filter device. Therefore, we propose a filter device for ink and coating preparation.

A second extension plate that cooperates with the second inclined plate is fixedly connected to the outer surface of the filter device housing.

[0009] Preferably, the top of the scraper is provided with a beveled block, and one side of the beveled block is fixedly connected to the inner wall of the filter housing.

[0010] Preferably, the scraper is fixedly connected to limit rods at both ends near the telescopic rod, and a through hole is provided on one side of the filter device housing for sliding connection with the limit rods.

[0011] Preferably, the bottom of the inclined block is fixedly connected to an intercepting plate that is slidably connected to the limiting rod and the telescopic rod, and the side of the intercepting plate near the scraper is fixedly connected to a material removal ring.

[0012] The technical effects and advantages of this utility model are as follows:

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a filtering device for preparing ink and coating, including a filter device housing 1, a boss 2 fixedly connected inside the filter device housing 1, a filter plate 3 slidably connected to the top of the boss 2, a guide plate 4 fixedly connected inside the filter device housing 1, the guide plate 4 being located at the bottom of the boss 2, a first discharge port 5 for cooperating with the guide plate 4 opening on one side of the filter device housing 1, a first extension plate 6 for cooperating with the first discharge port 5 fixedly connected to one side of the filter device housing 1, a scraper 7 slidably connected to the top of the filter plate 3, a telescopic rod 8 fixedly connected to one side of the scraper 7, a cylinder 9 for cooperating with the telescopic rod 8 fixedly connected to one side of the filter device housing 1, a second discharge port 11 for cooperating with the filter plate 3 opening on the other side of the filter device housing 1, and a first inclined plate 10 fixedly connected to the top of the scraper 7. After the coating is poured into the interior of the filter device housing 1, the coating... The filtered paint is guided by the guide plate 4 through the filter plate 3 and discharged into the interior of the filter device housing 1 through the first outlet 5. During discharge, the first extension plate 6 prevents the paint from flowing down the outer wall of the filter device housing 1, making it difficult to collect. When particles clog the surface of the filter plate 3, the cylinder 9 is activated to drive the telescopic rod 8, which in turn drives the scraper 7 to scrape off the particles on the surface of the filter plate 3. During scraping, the first inclined plate 10 can significantly increase the scraping amount. The movement of the scraper 7 allows the particles to be discharged through the second outlet 11, thus ensuring the filtration effect of the filter plate 3 and making the filtration efficiency more stable. The scraper 7 can effectively extend the service life of the filter plate 3, reduce the frequency of filter plate 3 replacement, thereby reducing the difficulty and cost of operation, improving the ink filtration efficiency, and ensuring the stability of ink processing efficiency.

[0023] Reference Figures 1-4As shown in this embodiment: a fixing block 12 is installed inside the second discharge port 11. Grooves 13 are provided at both ends of the fixing block 12. A fixing column 14 is slidably connected inside the groove 13. A control rod 15 is fixedly connected to the surface of the fixing column 14. A stroke groove 16 that cooperates with the control rod 15 is provided on one side of the fixing block 12. After the filter plate 3 is installed on the top of the boss 2, the fixing block 12 is installed inside the second discharge port 11. Then, the control rod 15 drives the fixing column 14 to be inserted into the inner wall of the filter device housing 1, so that the position of the fixing block 12 is fixed. The fixing of the fixing block 12 limits the filter plate 3 and prevents the filter plate 3 from shifting on the top of the boss 2. The top of the fixing block 12 is inclined, and the side closer to the filter plate 3 is lower than the side away from the filter plate 3. This can intercept the paint when filtering the paint and prevent the paint from flowing out. At the same time, the detachable design of the fixing block 12 can quickly replace the filter plate 3 when there is too much blockage inside the filter plate 3 and it is difficult to clean.

[0024] Reference Figure 4 As shown in this embodiment: a spring 17 is provided inside the groove 13. One end of the spring 17 is fixedly connected to the fixed post 14, and the other end of the spring 17 is fixedly connected to the inner wall of the groove 13. By setting the spring 17, when the fixed post 14 is inserted into the inner wall of the filter device housing 1, the fixed post 14 is limited. The thrust generated by the spring 17 can effectively prevent the fixed post 14 from shifting.

[0025] Reference Figure 3 As shown in this embodiment: a second inclined plate 18 is provided on the top of the fixed block 12, and both ends of the second inclined plate 18 are fixedly connected to the inner wall of the second discharge port 11. A second extension plate 19 that works in conjunction with the second inclined plate 18 is fixedly connected to the outer surface of the filter device housing 1. The discharge particles are guided by the second inclined plate 18 and the second extension plate 19, which makes it easier for workers to recycle them.

[0026] Reference Figure 3 As shown in this embodiment: the top of the scraper 7 is provided with a beveled block 20, one side of which is fixedly connected to the inner wall of the filter device housing 1. By setting the beveled block 20, the paint is intercepted and guided, preventing a large amount of paint from flowing into the connection between the telescopic rod 8 and the cylinder 9 when adding paint to the inside of the filter device housing 1, causing the paint to enter the inside of the cylinder 9 and damage the cylinder 9.

[0027] Reference Figure 2 and Figure 3As shown in this embodiment: both ends of the scraper 7 near the telescopic rod 8 are fixedly connected to limit rods 21, and a through hole 22 is provided on one side of the filter device housing 1 to be slidably connected and cooperated with the limit rod 21. By setting the limit rod 21, the movement of the scraper 7 is more stable, and the scraper 7 is effectively prevented from deflecting when moving.

[0028] Reference Figure 3 and Figure 5 As shown in this embodiment: the bottom of the inclined block 20 is fixedly connected to an intercepting plate 23 that is slidably connected to the limiting rod 21 and the telescopic rod 8. The side of the intercepting plate 23 near the scraper 7 is fixedly connected to a material removal ring 24. The material removal ring 24 intercepts the paint and scrapes off the paint on the surface of the limiting rod 21 and the telescopic rod 8, minimizing the adhesion of paint on the surface of the limiting rod 21 and the telescopic rod 8, so as to ensure the normal operation of the cylinder 9.

[0029] Working Principle: After the paint is poured into the interior of the filter housing 1, it is filtered through the filter plate 3. The filtered paint is then guided by the guide plate 4 and discharged through the first outlet 5 into the interior of the filter housing 1. During discharge, the first extension plate 6 prevents the paint from flowing down the outer wall of the filter housing 1, making it difficult to collect. When particles clog the surface of the filter plate 3, the cylinder 9 is activated to drive the telescopic rod 8, which in turn drives the scraper 7 to scrape off the particles from the surface of the filter plate 3. During scraping, the first inclined plate 10 significantly increases the scraping volume. The movement of the scraper 7 allows the particles to be discharged through the second outlet 11, thus ensuring the filtration effect of the filter plate 3 and making the filtration efficiency more stable. The scraper 7 also effectively extends the service life of the filter plate 3. The filter plate 3 has a longer lifespan, reducing the frequency of replacement and thus lowering the difficulty and cost of operation. This improves the ink filtration efficiency and ensures the stability of ink processing efficiency. After the filter plate 3 is installed on the top of the boss 2, the fixing block 12 is installed inside the second discharge port 11. Then, the control rod 15 drives the fixing column 14 to be inserted into the inner wall of the filter device housing 1, fixing the position of the fixing block 12. The fixing block 12 limits the filter plate 3 and prevents it from shifting on the top of the boss 2. The top of the fixing block 12 is inclined, with the side closer to the filter plate 3 being lower than the side farther away from the filter plate 3. This allows the coating to be intercepted during filtration, preventing it from flowing out. The detachable design of the fixing block 12 allows for quick replacement of the filter plate 3 when there is too much blockage inside and it is difficult to clean.
