Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lithium battery electrode coating machines, specifically to an ink delivery device for a coating machine. Background Technology
[0002] In the production of lithium battery electrodes, the gravure coating process is a key step in achieving uniform coating of the electrodes by uniformly transferring the slurry onto the surface of the gravure roller.
[0003] In existing technologies, traditional gravure coating machines typically use a method where the gravure roller directly contacts the slurry tank for slurry application. This means the gravure roller is immersed directly into the slurry tank at a high speed, and the slurry is carried by the pits or textures on the roller surface before being transferred to the substrate surface. However, because the gravure roller is in direct contact with the slurry and operates at a high speed, the slurry is easily thrown off the roller surface due to centrifugal force. This not only wastes the slurry but also contaminates the equipment floor and other components, increasing cleaning costs and impacting the production environment. Utility Model Content

[0019] See Figures 1-2 , Figure 1 This is a schematic diagram of the coating device and ink delivery device in the embodiment. Figure 2 This is a schematic diagram of the ink delivery device structure in the embodiment. The ink delivery device of a coating machine in this example includes a coating device 1 and an ink delivery device 2. The device has a coating roller 11. The ink delivery device 2 is mounted on the coating device 1 and includes two sets of mounting frames 21 and an ink delivery mechanism 22. The mounting frames 21 are mounted on both sides of the coating device 1. The ink delivery mechanism 22 includes an ink delivery roller 221, a drive mechanism 222, and two sets of proximity mechanisms 223. The two sets of proximity mechanisms 223 are respectively disposed on the two sets of mounting frames 21. The two ends of the ink delivery roller 221 are respectively mounted on the proximity mechanisms 223 and are parallel to the coating roller 11. The drive mechanism 222 is disposed on one set of mounting frames 21 and is driven and connected to the ink delivery roller 221. The proximity mechanism 223 drives the ink delivery roller 221 to approach or move away from the coating roller 11. During operation, after the ink-dispensing roller 221 picks up the slurry, the approach mechanism 223 brings the ink-dispensing roller 221 close to the coating roller 11 and evenly coats the coating roller 11 with the slurry. This effectively prevents the coating roller 11 from splashing the slurry with its high-speed rotation after picking it up, thus preventing contamination and waste. In this example, the drive mechanism 222 uses a pulley drive system to drive the ink-dispensing roller 221 to rotate.
[0020] Specifically, the coating apparatus 1 also includes a lifting trough 12, a traction roller 13, and a doctor blade 14. The lifting trough 12 is located below the coating roller 11 and the ink delivery roller 221, the traction roller 13 is located above the coating roller 11, and the doctor blade 14 is mounted on the lifting trough 12 and directly opposite the coating roller 11. The traction roller 13 is used to pull the material, the doctor blade 14 is used to scrape off excess slurry on the coating roller 11, and the lifting trough 12 is used to provide slurry for the ink delivery roller 221 to pick up, while also receiving the slurry scraped off by the doctor blade 14.
[0021] Furthermore, the proximity mechanism 223 includes a linear drive 2231 and a rotating plate 2232. One end of the linear drive 2231 is fixed to the coating apparatus 1, and the other end is drivenly connected to the bottom end of the rotating plate 2232. The middle part of the rotating plate 2232 is rotatably connected to the mounting bracket 21, and the ink delivery roller 221 is rotatably connected to the top end of the rotating plate 2232. The drive mechanism 222 is located on the outside of the rotating plate 2232. During operation, the linear drive 2231 drives the rotating plate 2232 to rotate, causing the ink delivery roller 221 to approach the coating roller 11. In this example, the linear drive 2231 is a cylinder.
[0022] Specifically, the mounting bracket 21 has a rotating shaft 211, and the rotating plate 2232 is provided with a connecting hole corresponding to the rotating shaft 211. It is rotatably connected to the rotating shaft 211 through the connecting hole. A bearing is provided in the connecting hole and connected to the rotating shaft 211.
[0023] Furthermore, the ink delivery device 2 also includes two sets of limiting devices 23. The limiting devices 23 are located on the side of the mounting frame 21 facing away from the rotating plate 2232, and include a linear drive assembly 231 and a limiting block 232. The limiting block 232 is throttle-connected to the linear drive assembly 231. The rotating plate 2232 has a limiting post 22321 located between the connecting hole and the linear drive assembly 2231, with its other end passing through the mounting frame 21 and protruding onto the moving path of the limiting block 232. The mounting frame 21 also has an arc-shaped hole 212 located below the connecting hole. One end of the limiting post 223 passes through the arc-shaped hole 212 and protrudes onto the moving path of the limiting block 232. Further still, the linear drive assembly 231 includes a drive member 2311 and a lead screw assembly 2312. The drive member 2311 is throttle-connected to one end of the lead screw assembly 2312, and the limiting block 232 is throttle-mounted on the lead screw assembly 2312. Among them, the drive component 2311 adopts a manual knob.
[0024] During operation, the linear drive assembly 231 adjusts the position of the limit block 232 to limit the movement distance of the limit post 22321, thereby limiting the rotation angle of the rotating plate 2232, thus limiting the position of the ink delivery roller 221 and facilitating adjustment.
[0025] Preferably, the top of the rotating plate 2232 is also provided with a U-shaped opening 22322 and a cover plate 22323. The cover plate 22323 covers the opening of the U-shaped opening 22322, and one end of it is rotatably connected to the rotating plate 2232. In a specific implementation, a bearing is provided inside the U-shaped opening 22322 for connecting the ink delivery roller 221. It can be understood that when the ink delivery roller 221 needs to be replaced, the cover plate 22323 can be opened directly to remove the ink delivery roller 221, which facilitates the replacement of the ink delivery roller 221 and improves the convenience of use.
[0026] In summary, in this example, by setting up an ink transfer device to assist the coating roller in picking up the slurry in the coating device, the high-speed rotating coating roller can effectively prevent the picked-up slurry from flying away during operation, which not only reduces slurry waste but also effectively prevents environmental pollution.
[0027] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
