[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This invention addresses the environmental problems and ink waste associated with current open-type ink tank systems for sizing micro-grooves. The following technical solution is provided: Figures 1-6 As shown, a closed ink tank device for lithium battery separator micro-concave rollers includes an ink tank 1. The side of the ink tank 1 facing the micro-concave roller 32 is open. Plugs 4 are provided at both ends of the ink tank 1. At least one drain port 12 and at least one inlet port 13 connected to a slurry container are provided inside the ink tank 1. An upper scraper blade 2 and a lower scraper blade 3 are respectively provided on the upper and lower sides of the open side of the ink tank 1. The lower scraper blade 3 contacts the micro-concave roller 32 to seal the slurry in the ink tank 1. The upper scraper blade 2 is used to scrape the slurry evenly on the surface of the micro-concave roller 32. By setting an ink tank 1 with one side open and upper and lower scraper blades 2 and 3, a closed ink tank device is formed, solving various problems of existing open ink tanks.

[0024] Specifically, the upper scraper blade 2 and the lower scraper blade 3 are installed on the upper and lower inclined surfaces of the open opening of the ink tank 1. The end cap 4 can be detachably connected to the end of the ink tank 1. The end cap 4 can be made of EVA material. The drain port 12 can be set on the lower side of both ends of the inner cavity of the ink tank 1. When cleaning the inner cavity of the ink tank 1, the slurry or clean water can be discharged from both ends.

[0025] Two liquid inlets 13 can be set in the middle of the inner cavity of ink tank 1. They are connected to the slurry container through a liquid pump, which can pump the slurry in the slurry container into the inner cavity of ink tank 1 to fill it.

[0026] In this embodiment, overflow holes 11 are provided on the upper sides of both ends of the ink tank 1. An overflow switching valve assembly 6 is installed on the outside of the ink tank 1, which is connected to the corresponding overflow holes 11 and drain ports 12. The overflow switching valve assembly 6 can collect excess ink in the ink tank 1. It can also be connected to the drain port 12 during cleaning to facilitate the entry and exit of clean water. This way, the ink tank 1 and the micro-concave roller 32 do not need to be disassembled during cleaning. At the same time, the overflow switching valve assemblies 6 are connected to each other through a return pipe 7 located on the lower side of the ink tank 1. The return pipe 7 is connected to the ink container. By setting up the return pipe 7, the overflow ink of the overflow switching valve assembly 6 can be collected in a unified manner, which is convenient and quick.

[0027] Specifically, when the ink tank 1 is full of ink, the ink enters the overflow valve group 6 from the overflow hole 11 on the top of the ink tank, and then returns to the ink container through the return pipe 7. At this time, the pipeline between the overflow switching valve group 6 and the drain port 12 is not connected, and the cleaning function cannot be used.

[0028] When the inner cavity of ink tank 1 needs to be cleaned, the overflow switching valve group 6 is activated, switching the connection to the drain port 12 and the inlet port 13 to the clean water source. At the same time, the return pipe 7 can also be replaced and connected to other containers. The pump draws clean water into the inner cavity of ink tank 1 to rinse the inner cavity. Then the clean water enters the return pipe 7 from the drain port 12 and is discharged in a unified manner. The entire process does not require disassembly of the structure of ink tank 1.

[0029] In this embodiment, as Figure 4 As shown, a main receiving tray 30 is installed below the ink tank 1, which houses the micro-concave roller 32 within its range. This tray can collect the ink dripping from the micro-concave roller 32 and the ink tank 1, thus preventing environmental pollution. Simultaneously, a leakage receiving tray 31 is installed inside the main receiving tray 30, located directly below the micro-concave roller 32. The leakage receiving tray 31 collects the ink dripping from the micro-concave roller 32 separately. The position of the leakage receiving tray 31 can be adjusted according to the position of the micro-concave roller 32. The main receiving tray 30 can be mounted on a fixed bracket. Both the main receiving tray 30 and the leakage receiving tray 31 have a V-shaped cross-section for convenient ink collection.

[0030] In this embodiment, as Figures 1-5As shown, the ink tank 1 is mounted on the ink tank mounting frame 5. Both ends of the ink tank mounting frame 5 are connected to ink tank moving components 8. The ink tank moving component 8 includes a fixed base 23 and a cylinder 20 mounted on the fixed base 23. The extended end of the cylinder 20 is connected to a slide table 24 slidably disposed on the fixed base 23. The slide table 24 is connected to the ink tank mounting frame 5. By working in unison with the cylinders 20 on the two ink tank moving components 8, the relative position between the micro-concave roller 32 and the ink tank 1 can be quickly switched, thereby facilitating the replacement of parts or maintenance during shutdown.

[0031] Among them, such as Figures 5-6 As shown, the fixed base 23 is also equipped with a fine-tuning mechanism 21 connected to the slide table 24. The fine-tuning mechanism 21 includes a nut adjustment block 43 connected to the slide table 24. A lead screw 42 is horizontally arranged on the fixed base 23. A handwheel 41 is installed at one end of the lead screw 42, and the other end of the lead screw 42 is threadedly connected to the nut adjustment block 43. The fine-tuning mechanism 21 can precisely adjust the distance between the upper doctor blade 2 and the lower doctor blade 3 of the ink tank 1 and the micro-concave roller 32 within a small range. Specifically, the lead screw 42 is rotated by rotating the handwheel 41, thereby driving the nut adjustment block 43 and the slide table 24 to make fine-tuning movements, thereby achieving the purpose of precisely adjusting the position of the upper doctor blade 2 and the lower doctor blade 3.

[0032] Meanwhile, the slide table 24 is equipped with a limiting block 22 that cooperates with the fixed seat 23, which can limit the travel distance of the ink tank 1 and prevent the ink tank 1 from colliding with the micro-concave roller 32.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, in this utility model, descriptions involving terms such as "primary," "secondary," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
