[0002] A coating device is a mechanical device used to evenly coat specific functional materials such as glue, paint, or ink on the surface of substrates such as films and papers. A coating device is required in the production process of non-woven fabrics. The coating device is usually equipped with guiding, tensioning, and drying mechanisms to achieve efficient and uniform coating effects.

[0003] Chinese Patent CN217699941U discloses a coating device for continuous production of non-woven fabrics, specifically related to the technical field of coating machines, including a paint tank. One side inside the paint tank is rotatably connected with a first guiding roller. The first guiding roller is rotatably connected to the right side of the paint tank. A second guiding roller is installed on the left side of the first guiding roller. An inner scraper is installed on the side of the paint tank away from the first guiding roller. The inner scraper is fixedly installed on the left side of the second guiding roller. And the original cloth passes through the bottom of the inner scraper and then is connected with a third guiding roller rotatably connected to the inside of the upper surface of the paint tank. The third guiding roller is placed between the first guiding roller and the inner scraper. Adjustable side scrapers are installed on both sides of the inner scraper inside the paint tank. The side scrapers are arranged between the third guiding roller and the inner scraper, and double-sided decontamination is carried out through the two side scrapers to improve the decontamination effect of the paint on the surface of the original cloth.

[0004] In the above patent, when adjusting the angle of the side scraper, it is necessary to first loosen the nut, then rotate the side scraper to the appropriate angle according to the required angle, and then rotate the nut to make it fit tightly with the outer wall of the paint tank to fix the side scraper. However, during the process of fixing the side scraper, it is necessary to hold the end of the shaft rod to keep the position unchanged while tightening the bolt. Due to the self-weight of the side scraper, it is relatively laborious to hold the end of the shaft rod; if holding the side scraper, the paint adhered to the side scraper will attach to the staff's hands.
