[0041] Example:

[0042] See also Figure 1-2 The continuous micro-groove roller coating mechanism in the preferred embodiment of the utility model includes a conveying component, a scraper component 5 and a lifting component 4, so as to continuously convey the film 1 through the transmission component, and coat the grooves on the surface of the film 1 through the scraper component 5, and scrape off the solution on the surface of the film 1 outside the grooves.

[0043] Specifically, if Figure 1 As shown in the figure, the conveying component in the preferred embodiment includes an unwinding structure, a winding structure (not shown in the figure) and a plurality of back rollers 2 arranged at intervals therebetween, so as to continuously unwind the film 1 through the unwinding structure and continuously wind up the coated film through the winding structure, and at the same time, the conveying speed of the film 1 is controlled by the unwinding structure and / or the winding structure.

[0044] At the same time, multiple back rollers 2 are installed on the frame 3 at intervals and rotated. The film 1 released by the unwinding structure passes around each back roller 2 in turn to support the film 1 through the back roller 2. The back roller 2 with a certain arc supports the micron-level grooves on the surface of the film 1 in a relaxed state, making it easier for the coating solution to be scraped into the grooves.

[0045] Furthermore, if Figure 2 As shown in the figure, the scraper assembly 5 is arranged corresponding to any one of the back rollers 2 to coat and fill the grooves on the surface of the film 1 after being supported and stretched by the back roller 2; at the same time, the scraper assembly 5 is connected and arranged on the lifting assembly 4, so that the scraper assembly 5 is driven by the lifting assembly 4 to move up and down relative to the back roller 2, so that when the film 1 needs to be rerolled or passes through an area on the film 1 that does not need to be coated, the scraper assembly 5 is controlled by the lifting assembly 4 to rise and avoid.

[0046] Specifically, the scraper assembly 5 in the preferred embodiment includes a scraper 501 and a coating structure; wherein the scraper 501 is connected to the lifting assembly 4 through a scraper fixing seat 503, and the scraper 501 is rotatably connected to the scraper fixing seat 503 to rotate the scraper 501 according to the required coating thickness to adjust the action angle of the scraper 501.

[0047] In actual setting, the scraper 501 is a soft scraper with a certain hardness and toughness. It is further preferred that the scraper 501 is a soft scraper with a Shore hardness of 50 to 70 degrees, so as to ensure that the grooves of the film 1 are filled and the solution outside the grooves is scraped clean without causing additional damage to the film 1.

[0048] Preferably, the blade of the scraper 501 is an oblique or pointed blade with an angle of 45 to 120 degrees.

[0049] Preferably, the scraper assembly 5 further includes a knife holder 504, which is rotatably connected to the scraper fixing seat 503, and the scraper 501 is fixed on the knife holder 504, so that the soft scraper 501 is supported by the knife holder 504 to ensure its straightness.

[0050] like Figure 2 As shown in the figure, the scraper 501 can rotate around the rotation center 505. During the actual setting, after the film 1 passes through the scraper assembly 5 and the back roller 2, the scraper 501 is lowered to the rotation center 505 to coincide with the tangent point of the film 1 and the back roller 2, so that the scraper 501 can contact the surface of the film 1 with a certain pressure through the deformation of the soft scraper, further ensuring the scraping effect of the scraper 501, and being able to scrape off the coating solution on the surface of the film 1.

[0051] Furthermore, the coating structure includes a liquid outlet 502, which is fixedly connected to the blade holder 504 and is arranged on the front side of the scraper 501 along the conveying direction of the film 1, so as to adjust the liquid outlet angle along the rotation of the blade holder 504, and can drip the solution onto the surface of the film 1 at a certain liquid outlet speed; thereafter, the solution is scraped into the groove on the surface of the film 1 by the scraper 501, and the solution in the area outside the groove is scraped off.

[0052] In a preferred embodiment, the coating structure is connected to a PLC and a metering pump so that the liquid outlet speed of the liquid outlet 502 is controlled by the PLC and the metering pump so that the liquid outlet speed of the liquid outlet 502 matches the conveying speed of the film 1. It is further preferred that the liquid outlet speed of the liquid outlet 502 is proportional to the conveying speed of the film 1 to ensure the uniformity of the coating.

[0053] Furthermore, the lifting assembly 4 in the preferred embodiment includes a lifting cylinder 402, a guide rail 401 and a slide 403, wherein the guide rail 401 is arranged vertically and fixedly set on the frame 3; the slide 403 is slidably matched and connected to the guide rail 401, and the lifting cylinder 402 is fixedly set on the frame 3, and its lifting end is fixedly connected to the slide 403, so as to drive the slide 403 to perform lifting and lowering movements along the guide rail 401 through the lifting cylinder 402.

[0054] Accordingly, the scraper assembly 5 is fixedly connected to the slide 403, and then the scraper assembly 5 is driven to move up and down through the slide 403 to adjust the downward pressing position of the scraper assembly 5 and the preload force of the coating.

[0055] like Figure 1 In the preferred embodiment shown, lifting assemblies 4 are respectively provided on the frame 3 corresponding to the scraper assemblies 5 on both sides along the feeding direction of the film 1, and pressure reducing valves 404 are respectively provided on the frame 3 corresponding to the two lifting assemblies 4, so as to adjust the pressure of the lifting cylinder 402 through the pressure reducing valve 404 to ensure that the preload force on both sides of the scraper assembly 5 is consistent.

[0056] Further preferably, micrometers 405 are respectively provided on the frame 3 corresponding to the two lifting assemblies 4, so as to monitor whether the downward pressure position values ​​at both ends of the scraper assembly 5 are consistent through the micrometer 405. When the position values ​​at both ends are inconsistent, the downward pressure position of the scraper 501 is adjusted in time through the lifting cylinder 402 to ensure the uniformity of coating and scraping.

[0057] In actual use, the mechanism can be debugged first, and the pressure of the scraper 501 can be tested by a pressure test paper, so as to ensure the consistency of the position of the scraper 501 and the accuracy of the pressure through dual control of pressure and position.

[0058] Preferably, a visual inspection device is also provided in the continuous micro-groove roller coating mechanism, which is arranged downstream of the scraper assembly 5 along the conveying direction of the film 1, so that after the coating is completed, the coating effect can be inspected by the visual inspection device.

[0059] The continuous micro-groove roller coating mechanism in the utility model has a reasonable and ingenious structural design, realizes continuous coating and scraping of the film, improves the coating effect of the film, and improves the uniformity and quality of the coating, and has good application prospects and promotion value.
