[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] like Figure 1-3 As shown, the utility model proposes a coating machine scraping device, including a scraper 2, the end of the scraper 2 is detachably fixedly connected to the scraper end connecting shaft 21 by bolts, and the detachable connection facilitates the disassembly and assembly between the scraper 2 and the following scraping thickness adjustment mechanism 3.
[0025] In this embodiment, the coating machine scraper device also includes a scraper thickness adjustment mechanism 3 for facilitating accurate adjustment of the distance between the scraper 2 and the coating roller 1. The scraper thickness adjustment mechanism 3 includes a main substrate 31, one end of which is fixedly connected to an external fixing member such as a coating machine housing through a fixed hole 311. The other end of the main substrate 31 is vertically slidably connected to a pair of positioning clamps 36 and is rotatably connected to a second adjustment screw 37, and the two ends of the second adjustment screw 37 are respectively threadedly engaged with the corresponding positioning clamps 36, so that when the second adjustment screw 37 is rotated, the two positioning clamps 36 can be driven to separate and combine. When the two positioning clamps 36 are combined, they can clamp the roller end connecting shaft 11 coaxially fixed to the end of the coating roller 1, so that the main substrate 31 and the scraper 2 connected thereto are kept on the radial line of the coating roller 1, which is convenient for the subsequent measurement of the gap distance between the scraper 2 and the coating roller 1;
[0026] The main base plate 31 is provided with a guide slot 312, in which a guide slider 32 is slidably connected. The guide slider 32 is detachably sleeved with the scraper end connecting shaft 21 and fixed by a pin or other connecting member. One end of the first adjusting screw shaft 35 is rotatably connected with the guide slider 32, and the other end is threadedly engaged with the main base plate 31. Therefore, when the first adjusting screw shaft 35 is rotated, the threaded engagement between it and the main base plate 31 can drive the guide slider 32 to move along the guide slot 312, thereby driving the scraper 2 to move closer to or away from the coating roller 1 to adjust the gap between the two.
[0027] The outer wall of the scraper thickness adjustment mechanism 3 is provided with a scale bar 33 for indicating the moving distance of the scraper 2, and the outer wall of the guide slider 32 is fixedly connected with a pointer 34 for indicating the specific value of the scale bar 33. Since the diameter of the scraper 2 is determined, the value of the scale bar 33 corresponding to the outer ring surface of the scraper 2 can be known. In other embodiments, the pointer 34 can also be designed as a structure that can directly indicate the corresponding value of the outer ring surface of the scraper 2, which is not repeated here.
[0028] Based on the above, a pair of scraper thickness adjustment mechanisms 3 are provided and are respectively located at the two ends of the scraper 2. The difference between the two scraper thickness adjustment mechanisms 3 is that the first adjustment screw shaft 35 in one of the scraper thickness adjustment mechanisms 3 adopts a light rod, which is only used to provide movement guidance for the corresponding guide slider 32.
[0029] The working principle of this embodiment is: through the design of the scraper thickness adjustment mechanism 3, not only can the scraper 2 be kept on the radial line of the paint roller 1, but also its position can be quickly adjusted along the radial line, making it easier to adjust the gap between the scraper 2 and the paint roller 1.
[0030] Specifically, the second adjusting screw 37 is rotated, and the two positioning clamps 36 are screwed together by the second adjusting screw 37 and the two positioning clamps 36 to clamp the roller end connecting shaft 11, and the main base plate 31 is fixed to the external fixing parts such as the coating machine housing through the fixing hole 311. At this time, no matter how the scraper 2 is moved, it can be ensured that it is located on the radial line of the coating roller 1, which will help to measure the distance between the two later. When moving and adjusting the scraper 2, it is only necessary to rotate the first adjusting screw 35, and the screwing of the first adjusting screw 35 and the main base plate 31 drives the guide slider 32 to move along the guide slot 312, and the specific position of the scraper 2 is determined by the indication of the scale bar 33 by the pointer 34. Since the diameter of the scraper 2 is fixed, refer to Figure 2 , combined with the value of the scale bar 33 corresponding to the outer annular surface of the coating roller 1, the gap between the scraper 2 and the coating roller 1 can be obtained, and the gap is the thickness of the slurry to be coated.
[0031] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
