[0002] In the filtration of coatings, a relatively common method is to set a filter screen in a tank.

[0003] For example, the coating filter residue equipment with the application number CN202321662157.1 includes a storage barrel with a detachable top cover; a stirring assembly arranged in the storage barrel for stirring the coating in the storage barrel; a filtering assembly including a filtering element and a cleaning element. The filtering element is arranged in the middle of the storage barrel for filtering the coating, and the cleaning element is arranged on the stirring assembly, above the filtering element and in contact with the filtering element for cleaning the residue on the filtering element. The coating in the storage barrel is filtered by the filtering element, so that the pure coating falls to the bottom of the storage barrel, and the filter residue is isolated on the filtering element. Then, the filter residue on the filtering element is cleaned by the cleaning element to prevent the filtering element from being blocked. And the coating in the storage barrel is stirred by the stirring assembly to prevent the coating from solidifying due to too long standing time during the filtering process, effectively solving the problems that the filter screen is easy to be blocked, the filtering device needs to be cleaned frequently, resulting in reduced filter residue efficiency and increased work burden on the staff.

[0004] However, the above patent is not suitable for the operation of filtering residue of printing coatings. For example, since the particles in printing coatings are often very fine and may have strong adhesion, when using a brush to clean the surface of the filter plate, the structure of the brush has a poor fit with the filter plate and cannot achieve an effective cleaning effect.

[0005] In addition, due to the use characteristics of printing coatings, the filtering equipment needs to be cleaned frequently to ensure the filtering effect when filtering printing coatings.

Specific embodiments

[0033] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0034] The printing coating filter residue device according to the embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0035] As Figures 1 to 9 shown, the printing coating filter residue device according to the embodiment of the present utility model can not only improve the filter residue effect on the printing coating but also avoid the blockage of the filter residue through a multi-stage filter residue method and the scraping action of the scraping device 400.

[0036] For the coating filter residue equipment with the application number CN202321662157.1 (hereinafter referred to as "this patent"), a single-layer filter plate is provided, and a pullable filter frame is provided to collect impurities on the filter plate.

[0037] The printing coating filter residue device of the present utility model focuses on the applicability design according to the characteristics of the printing coating. Through the first screen 200 and the second screen 300 arranged from top to bottom, the printing coating in the tank 100 is screened and filtered multiple times, and impurities in the coating are removed. Not only can the printing coating be classified and screened out through the different screen holes of the first screen 200 and the second screen 300, but also the efficient scraping action of the scraping device 400 can be used to avoid the blockage of impurities on the first screen 200 and the second screen 300.

[0038] Specifically, when the relevant staff drives the rotating shaft 410 to rotate through the driving motor 600, the rotating shaft 410 drives the flexible structure 420 to rotate. Since the flexible structure 420 abuts against the first screen 200 and the second screen 300, the rotating flexible structure 420 can scrape the impurities on the first screen 200 and the second screen 300 more efficiently, effectively reducing the blockage of the coating on the first screen 200 and the second screen 300.

[0039] It should be noted that since the flexible structure 420 includes a clamping frame and a soft strip, wherein the clamping frame is arranged on the rotating shaft 410; the soft strip is detachably arranged on the clamping frame through bolts, and the soft strip abuts against the first screen 200 or the second screen 300, the soft strip can be a rubber strip with certain deformation and reset ability to abut against the first screen 200 or the second screen 300 in real time.

[0040] When the patent is internally cleaned, since its filter element and cleaning element cannot provide a flexible disassembly method, the effect of internal cleaning is poor. Only by pulling the filter frame, complete internal cleaning cannot be achieved, and it can only rely on the flushing action of cleaning water. However, due to many cleaning blind spots at that time, the cleaning efficiency is not good.

[0041] For the printing coating filter residue device of the present utility model, by detachably installing the first screen 200 and the second screen 300 on the tank body 100 respectively, and the driving motor 600 and the scraping device 400 are also detachable. When cleaning the inside of the tank body 100, the relevant staff separates the driving motor 600 from the scraping device 400, and takes out the first screen 200, the second screen 300 and the scraping device 400 from the tank body 100 together, then the inside of the tank body 100 can be cleaned, and the first screen 200, the second screen 300 and the scraping device 400 can be cleaned specifically, improving the cleaning effect.

[0042] Specifically, when the relevant staff need to clean the inside of the tank body 100, first, the relevant staff control the lifting device 700 to drive the tank cover 500 to rise, that is, by rotating the second threaded rod 730, the second threaded rod 730 drives the connecting frame 740 to rise, so as to drive the tank cover 500 to rise. When the tank cover rises, the clamping joint 601 of the driving motor 600 is separated from the connecting head 430, then the driving motor 600 is separated from the scraping device 400.

[0043] Then the relevant staff remove the bolts on the first screen 200, and through the adjustment of the limiting structure 103, that is, by rotating the first threaded rod 1032, the first threaded rod 1032 drives the pressing plate 1031 to move, so that the pressing effect on the second screen 300 is removed.

[0044] Then, the relevant staff take out the first screen 200, the second screen 300 and the scraping device 400 together for cleaning.

[0045] In summary, the filter residue device for printing coatings according to the embodiments of the present utility model improves the filter residue efficiency. Through the design of a double-layer screen (the first screen 200 and the second screen 300), effective filtration of particles with different particle sizes in the printing coating is achieved. In particular, the second screen 300 can further filter out finer particles, ensuring the purity of the coating. In cooperation with the flexible structure 420 of the scraping device 400, the filter residue on the first screen 200 and the second screen 300 can be effectively scraped off, avoiding the problem of insufficient screen fitting degree in the traditional brush cleaning method and improving the filter residue cleaning efficiency. The detachability and cleaning convenience of the device are enhanced. Both the first screen 200 and the second screen 300 adopt an easily detachable design, which is convenient for cleaning and replacement, improving the cleanliness and maintenance efficiency of the device. The rotating shaft 410 is rotatably arranged on the first screen 200 and the second screen 300 and is detachably connected to the output end of the driving motor 600 through the connecting head 430. When cleaning the inside of the tank body 100, the first screen 200, the second screen 300, and the scraping device 400 can be disassembled together as a whole.
