For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0053] Please refer to Figure 1. An adjustable scraping device for coating according to an embodiment of this application includes: a positioning component 10 and a plurality of scraper components 20. In this embodiment, the scraper component 20 is shown and described as an example in the embodiment shown in Figure 1.

[0054] The positioning assembly 10 includes a first track 11 and a first drive member 12. The first track 11 can be mounted on the frame 13. Specifically, the frame 13 can serve as a support structure for the entire adjustable scraper coating device and is located on the side of the material strip, for example, above the material strip, so that the scraper assembly 20 can scrape the material strip below it.

[0055] In this embodiment, the first track 11 is arranged across the material strip, that is, the length direction of the first track 11 is perpendicular to the length direction of the material strip. In the orientation of the structure shown in Figure 1, the length direction of the first track 11 is the x-axis direction; correspondingly, the length direction of the material strip is the y-axis direction.

[0056] Several scraper assemblies 20 are slidably disposed on the first track 11; the scraper assemblies 20 can slide along the first track 11 to position the scraping position according to the process design requirements; the scraper assemblies 20 are used to scrape the coating on the coating strip; the output end of the first drive member 12 is connected to several scraper assemblies 20 and is used to drive several scraper assemblies 20 to slide along the first track 11.

[0057] In this embodiment, the number of first tracks 11 is not limited, and there can be one or more, specifically, the first tracks 11 can provide guiding support for the scraper assembly 20.

[0058] In this embodiment, the number of first driving components 12 is not limited, and there can be one or more of them.

[0059] In one implementation, the first driving component 12 can be a motor and the number of motors is the same as the number of scraper assemblies 20, so that the first driving component 12 and the scraper assembly 20 are connected in a one-to-one correspondence, thereby driving the scraper assembly 20 to move along the x-axis direction, thereby adjusting the position of the scraper assembly 20 along the width of the material strip and adjusting the spacing between different scraper assemblies 20.

[0060] In one implementation, the number of first driving members 12 can be one. Specifically, a rotatable lead screw 14 is provided on the frame 13; several scraper assemblies 20 are all meshed with and connected to the lead screw 14; the output end of the first driving member 12 is connected to the lead screw 14, which is used to drive the lead screw 14 to rotate and thus drive the scraper assemblies 20 to slide. Thus, when the first driving member 12 is started, the lead screw 14 can simultaneously drive several scraper assemblies 20 to move along the x-axis.

[0061] Corresponding to the above embodiment, the scraper assembly 20 may be provided with a plurality of fastening mounting members 25. The fastening mounting members 25 are used to securely mount the support plate 21 onto the frame 13. When the fastening mounting members 25 are loosened, the support plate 21 can move along the first track 11 to adjust its position. When the fastening mounting members 25 are tightened, the support plate 21 is fixed to the frame 13. The tightness of the fastening mounting members 25 can be manually controlled by the operator. The connection between the fastening mounting members 25 and the frame 13 can be as follows: the frame 13 is provided with a clearance groove for the fastening mounting members 25 to move along the x-axis, allowing the loosened fastening mounting members 25 to move along the x-axis along with the support plate 21; when the fastening mounting members 25 are tightened, they press against the frame 13, thus fixing the support plate 21.

[0062] In a more specific embodiment, please refer to Figures 1 to 3. The scraper assembly 20 includes: a support plate 21, a scraper 22, and a dust removal assembly 30. The support plate 21 is slidably disposed on the first track 11 and connected to the output end of the first drive member 12. The scraper 22 is disposed on the support plate 21. The dust removal assembly 30 includes a suction pipe 31 and a brush 32 disposed on the support plate 21. The suction pipe 31 faces the scraper 22. The brush 32 abuts against the scraper 22.

[0063] The gear used to connect the lead screw 14 can be mounted on the support plate 21. When the first drive unit 12 is activated, the support plate 21 moves along the x-axis to adjust the position of the scraper 22 along the x-axis.

[0064] In practical applications, the scraper 22, acting on the coating of the material strip, generates impurities that can affect the material during the scraping process. These impurities can be removed via the suction pipe 31 to prevent them from affecting the material. Simultaneously, the inventors discovered that in addition to generating impurities, some coating residue remains on the scraper 22 during the scraping process, affecting the scraping effect. Therefore, this embodiment includes a brush 32 that abuts against the scraper 22, which removes residue during cleaning, thereby ensuring the effective scraping.

[0065] In one embodiment, the brush 32 can be a rolling brush roller, and is equipped with a brush roller motor capable of driving its rotation. In this embodiment, the length of the brush 32 can be configured to be greater than or equal to the width of the scraper 22, and the length direction of the brush 32 is parallel to the width direction of the scraper 22, so that the brush 32 can cover the width of the scraper 22. The width direction of the scraper 22 is the cutting edge direction of the scraper 22, which in this embodiment is the y-axis direction shown in Figure 2.

[0066] In another embodiment, referring to Figures 1 to 4, the brush 32 is a sliding cleaning structure. Specifically, the dust removal assembly 30 further includes: a second track 33 and a second drive member 34; the second track 33 is disposed on the support plate 21; the brush 32 is slidably disposed on the second track 33; the second drive member 34 is disposed on the support plate 21, and the output end of the second drive member 34 is connected to the brush 32 for driving the brush 32 to slide along the second track 33 to clean the surface of the scraper 22.

[0067] In one implementation, the length direction of the second track 33 can be the z-axis direction shown in Figure 2, that is, the vertical direction; the brush 32 covers the scraper 22 in the horizontal direction, that is, it covers the scraper 22 in the y-axis direction. In this case, the second drive member 34 can drive the brush 32 to move in the z-axis direction to increase the cleaning range and cleaning effect of the brush 32.

[0068] In another implementation, as shown in Figures 2 and 3, the length direction of the second track 33 is the y-axis direction shown in Figure 2, i.e., the horizontal direction. The width direction of the scraper 22 is the y-axis direction. When the second drive unit 34 is activated, it can drive the brush 32 to clean the scraper 22, ensuring the cleaning effect on the scraper 22.

[0069] In addition to the above-described arrangement, in practical applications, the width direction of the scraper 22 can be configured to be parallel or perpendicular to the width direction of the material strip. When the scraper 22 is used to scrape off excess coating slurry, its width direction is generally configured to be parallel to the width direction of the material strip, i.e., always in the x-axis direction; when the scraper 22 is used for local correction of the material strip, such as edge repair, its width direction is configured to be perpendicular to the width direction of the material strip. In the structures shown in Figures 1 and 2, the width direction of the scraper 22 is the y-axis direction.

[0070] Correspondingly, in the structures shown in Figures 1 and 2, the length direction of the second track 33 is the y-axis direction. When the second drive member 34 is activated, it can drive the brush 32 to move along the y-axis direction to clean the scraper 22. The second drive member 34 can be a cylinder. The travel distance of the brush 32 is greater than the width of the scraper 22.

[0071] In one embodiment, the dust removal assembly 30 includes at least two brushes 32; the brushes 32 are disposed individually or in combination on the side of the scraper 22, that is, one or more brushes 32 may be disposed on the side of the scraper 22.

[0072] In this embodiment, brushes are provided on both sides of the scraper 22 so that the brushes 32 can clean both sides of the scraper 22 at the same time.

[0073] In another embodiment, please refer to Figure 2, the suction pipe 31 is an expanded pipe structure with an increased diameter along the air intake direction; the scraper 22 is disposed at the air intake of the suction pipe 31.

[0074] The expanded tube structure causes the air pressure inside the suction tube 31 to gradually decrease along the air intake direction, which helps to adsorb debris.

[0075] In a further improved embodiment, a suction groove 35 is provided at the air inlet of the suction pipe 31; the scraper 22 passes through the suction groove 35 so that the outer periphery of the scraper 22 is surrounded by the suction groove 35.

[0076] In this embodiment, a flat, sheet-like portion 36 may be provided at the air inlet of the suction pipe 31; the suction groove 35 is provided on the flat portion 36, and the suction groove 35 surrounds the outer periphery of the scraper 22, thereby achieving a comprehensive and uniform suction effect on the outer periphery of the scraper 22.

[0077] In this embodiment, the suction pipe 31 is disposed at the edge of the support plate 21; the scraper 22 extends out of the support plate 21 through the suction groove 35.

[0078] Optionally, the brush 32 is disposed on the side of the suction pipe 31 near the material belt, specifically in the gap between the suction pipe 31 and the material belt, so that the debris swept off by the brush 32 can be absorbed by the suction pipe 31.

[0079] In one embodiment, the scraper assembly 20 includes: a third track 23 and a third drive member 24; the third track 23 is disposed on the support plate 21; the scraper 22 is disposed on the third track 23 and is capable of sliding along the third track 23 to approach or move away from the material belt; the third drive member 24 is disposed on the support plate 21 and its output end is connected to the scraper 22 for driving the scraper 22 to slide.

[0080] Specifically, the third driving component 24 can also be a cylinder. The third driving component 24 can drive the scraper 22 to move, thereby adjusting its distance from the material belt. In this embodiment, the length direction of the third track 23 is the z-axis direction.

[0081] Optionally, the scraping device with adjustable scraper position also includes several displacement sensors 40; the several displacement sensors 40 are disposed on the frame 13 and are used to sense the position of several scraper assemblies 20.

[0082] The method by which the displacement sensor 40 senses the stroke and position of the scraper assembly 20 is existing technology and will not be described in detail in this embodiment. The displacement sensor 40 can sense the position of the scraper assembly 20, thereby enabling automatic adjustment of the scraper assembly 20's position in conjunction with the processor after the operator inputs parameters.

[0083] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
