Description

Technical Field

[0001] This application relates to the field of coating technology, specifically to a coating diaphragm device that can reduce the amount of dry material on both sides of an anilox roller. Background Technology

[0002] To ensure increased production efficiency, the required linear speed of base film coating equipment is gradually increasing. Common coating equipment can reach coating speeds of 180 m / min or even higher. This speed increase not only places higher demands on the equipment but also raises concerns about a series of product quality issues caused by high speeds, significantly reducing product yield. The most crucial structure of the coating machine is the coating head, which directly impacts product yield. With the increase in speed, current equipment only optimizes easily worn parts such as bearings and belts, without much optimization of the coating head structure. As the linear speed of the coating equipment increases, the anilox roller speed also increases, leading to increased material load. Over time, the smooth surfaces on both sides of the anilox roller and the foam on both sides of the material box experience wear, resulting in severe material leakage on both sides of the material box. The friction between the anilox roller and the sides generates heat, causing the slurry on both sides to gradually dry. The slurry and dry material are ejected at high speed by the anilox roller, with the dry material being thrown onto the film surface, creating uncoated areas and directly affecting product quality.

[0003] Therefore, it is necessary to provide a coating diaphragm device that can reduce the amount of dry material on both sides of the anilox roller to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a coating diaphragm device that can reduce the amount of dry material on both sides of the anilox roller, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: a coating diaphragm device that can reduce the dry material on both sides of the anilox roller, including a frame, an anilox roller is connected to the frame by a drive device, a receiving tray is provided below the anilox roller, the receiving tray is located between the frames, and smooth surfaces and transmission parts are symmetrically arranged at both ends of the anilox roller, the transmission part is located at the outermost end of the anilox roller and is rotatably connected to the frame;

[0006] The frame is also equipped with a dripping unit and a scraping unit. The scraping unit abuts against the outer peripheral wall of the light-emitting surface, and the dripping unit is located above the light-emitting surface.

[0007] Furthermore, the light-emitting surfaces are all located directly above the receiving tray.

[0008] Furthermore, the dripping unit includes a bracket rotatably connected to the frame, the bracket being located in front of the anilox roller, one end of the bracket being fixedly connected to a rotating shaft, the bottom of the rotating shaft being rotatably connected to a platform, and a bamboo tube being provided on the platform.

[0009] Furthermore, one end of the bamboo tube is connected to a throttle valve, and the other end is connected to a nozzle. The outer wall of the nozzle is fixed to the platform and located directly above the polished surface.

[0010] Furthermore, one end of the throttle valve has a water inlet, which is connected to a pure water tank via a pipe.

[0011] Furthermore, the scraping unit includes a connecting frame fixedly connected to the frame, the connecting frame being located behind the anilox roller, a telescopic column being slidably connected to the front of the connecting frame, and a handle being threadedly connected to the front end of the telescopic column.

[0012] Furthermore, one end of the telescopic column extends toward the anilox roller to form a scraper, the surface of which contacts the outer peripheral wall of the smooth surface.

[0013] The beneficial effects of this application are as follows: The coating diaphragm device provided by this application can reduce the amount of dry material on both sides of the anilox roller. By setting up a drip unit to discharge pure water, it not only wets the residual slurry on the smooth surface but also cools the anilox roller, preventing the phenomenon of heat generated during the running-in of the two sides of the anilox roller and the gradual formation of dry slurry on both sides. By setting up a scraper to scrape off the slurry remaining on the smooth surface, it prevents the material leakage on both sides of the anilox roller from forming dry material, which would then be thrown onto the film surface and directly affect the quality of the product.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1-4 As shown, this application provides a technical solution: a coating diaphragm device that can reduce the amount of dry material on both sides of an anilox roller, including a frame 1, an anilox roller 2 connected to the frame 1 by a drive device, a receiving tray 5 arranged below the anilox roller 2, the receiving tray 5 being located between the frames 1, and smooth surfaces 21 and transmission parts 22 symmetrically arranged at both ends of the anilox roller 2, the transmission part 22 being located at the outermost end of the anilox roller 2 and rotatably connected to the frame 1;

[0025] The frame 1 is also equipped with a dripping unit and a scraping unit. The scraping unit abuts against the outer peripheral wall of the smooth surface 21, and the dripping unit is located above the smooth surface 21.

[0026] The smooth surface 21 is directly above the receiving tray 5.

[0027] The dripping unit includes a bracket 3 that is rotatably connected to the frame 1. The bracket 3 is located in front of the anilox roller 2. One end of the bracket 3 is fixedly connected to a rotating shaft 31. The bottom of the rotating shaft 31 is rotatably connected to a platform 32. A bamboo tube 4 is also provided on the platform 32.

[0028] One end of the bamboo tube 4 is connected to a throttle valve 41, and the other end is connected to a nozzle 43. The outer wall of the nozzle 43 is fixed on the platform 32 and located directly above the smooth surface 21.

[0029] One end of the throttle valve 41 has a water inlet 42, which is connected to the pure water tank through a pipe.

[0030] The scraping unit includes a connecting frame 6 fixedly connected to the frame 1. The connecting frame 6 is located behind the anilox roller 2. A telescopic column 7 is slidably connected to the front of the connecting frame 6. A handle 71 is threadedly connected to the front end of the telescopic column 7.

[0031] One end of the telescopic column 7 extends toward the anilox roller 2 to form a scraper 72, and the surface of the scraper 72 contacts the outer peripheral wall of the smooth surface 21.

[0032] In one embodiment, the device reduces dry material residue.

[0033] Specifically, rotate the bracket 3, then continue rotating the platform 32, so that the nozzle 43 of the bamboo tube 4 is aligned directly above the smooth surface 21. Rotate the handle 71 to pull the telescopic column 7, so that the scraper 72 contacts the smooth surface 21. When the entire device starts working, driven by the drive device, the anilox roller 2 begins to rotate and coat the film to be coated. During coating, the main body of the anilox roller 2 is subjected to the pressure of the film and the centrifugal force during high-speed rotation, which throws the slurry on it towards the smooth surface 21 at both ends of the anilox roller 2. When rotating, the anilox roller 2 heats up, causing the slurry on the smooth surface 21 to solidify. At this time, the throttle valve 41 is opened, and pure water flows from the water tank through the pipe into the bamboo tube 4, and then drips from the nozzle 43 onto the smooth surface 21. This wets the slurry on the smooth surface 21 and cools the anilox roller 2. Then, under the action of the scraper 72, the slurry on the smooth surface 21 is scraped off, so that the slurry falls into the receiving tray 5, preventing material leakage from both sides of the anilox roller 2 and the formation of dry material, which is then thrown onto the film surface.

[0034] In summary, this device, by discharging pure water through a dripping unit, not only wets the residual slurry on the smooth surface 21 but also cools the anilox roller 2, preventing the slurry on both sides of the anilox roller 2 from gradually drying due to heat generated during wear. The scraper 72 removes the slurry remaining on the smooth surface 21, preventing material leakage from both sides of the anilox roller 2 and the formation of dry material that could be thrown onto the film surface, directly affecting the quality of the product.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. 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.
