Description

Technical Field

[0001] The utility model relates to the technical field of coating and scraping, in particular to a measurable scraping device. Background Art

[0002] In recent years, with organic flexible substrates as supports, various functional solutions are coated on their surfaces to achieve various functions of membrane products. The coating methods for achieving and completing various thin films are also gradually enriched and improved. Representative coating methods include: scraping, slit extrusion coating, dipping, curtain coating, micro-concave coating, roller coating, spin coating and other coating methods. The above coating methods can be classified into metered coating and non-metered methods according to the feeding method. Scraper coating is to place the coating on the surface of the substrate, and then control the gap between the scraper (steel, ceramic, etc.) and the substrate. During the relative movement of the substrate and the substrate, the excess slurry is scraped away to form a flat coating on the surface of the substrate, and finally the plane coating is completed. In view of the different properties of the coating slurry and the substrate, the material and shape design of the scraper have been greatly expanded, such as the comma scraper form widely used in the coating industry. With the continuous improvement of the precision of intelligent position control, the application of scraper coating has been expanded to the field of micron-level thin film coating.

[0003] Although the simplicity of the scraper mechanism and the ease of adjustment and cleaning during the process have great advantages over other coating methods, the non-metering feeding system limits the wider application of this method. Utility Model Content

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] Example

[0018] like Figure 1 As shown, a measurable scraping device includes a liquid slope module 1 and a scraper position module 2 arranged on the other side thereof, a liquid slope 3 is placed on the upper end of the scraper position module 2, and a scraping gap is formed between the scraper position module 2, the liquid slope 3 and the liquid slope module 1.

[0019] In this embodiment, a first flow slope position regulating device 5 is provided at the lower end of the other side of the flow slope module 1 away from the scraper position module 2, and a second flow slope position regulating device 6 is provided at the upper end of the other side of the flow slope 3 away from the flow slope module 1. A volume scale 4 is provided on both the flow slope module 1 and the flow slope 3. The first flow slope position regulating device 5 is used to adjust the scraping gap width d, and the second flow slope position regulating device 6 is used to adjust the scraping gap height h. First, the solution is injected into the inner groove formed between the flow slope 3 and the flow slope module 1; according to the display of the volume scale 4, the flow slope module 1, the scraper position module 2 and the flow slope 3 are adjusted simultaneously by the first flow slope position regulating device 5 and the second flow slope position regulating device 6 to control the scraper height h and the flow slope gap d;

[0020] The structural layout of the scraper coating mechanism and the fine-tuning position layout of the upper and lower and left and right modules have nothing to do with the specific adjustment details of the mechanism, the material and shape (angle) of the modules (including the scraper), the type of special surface coating treatment on the surface of each module, the type of coating solution, the process content used in the coating process, and the coating process for controlling the gap adjustment mechanism between the coating mechanism as a whole and the substrate.

[0021] like Figure 2 As shown, firstly, the solution 8 is placed on the surface of the substrate 7, which can be a rigid substrate or a flexible substrate, and then the gap between the scraper 10 (steel, ceramic, etc.) and the substrate 7 is controlled by a fine-tuning mechanism to control the relative movement between the scraper 10 and the substrate 7. The scraper 10 can scrape away excess slurry to form a smooth coating 9 on the surface of the substrate 7, and finally complete the scraper coating. The scraper coating method can achieve micron-level coating. The scraper coating method belongs to contact coating. In order to obtain a more perfect coating surface result, the blade of the scraper 10 needs to be precisely processed and structurally designed.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
