Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 5As shown, a coating device for lithium battery processing according to this utility model includes a housing 1; the top of the housing 1 has a feed inlet, and the bottom of the housing 1 has a discharge outlet. A movable frame 12 is slidably connected to the inner side of the housing 1, and the movable frames 12 are symmetrically arranged. A coating roller 13 is rotatably connected to the inner side of the movable frame 12. A liquid storage tank 14 is fixedly connected to the inner side of the movable frame 12. The liquid storage tank 14 is slidably connected to the coating roller 13. An inlet pipe is connected to the side of the liquid storage tank 14, and the inlet pipe is slidably connected to the housing 1. The front of the housing 1... A groove 15 is provided on the side. A moving block 16 is fixedly connected to the front side of the moving frame 12. The moving block 16 is slidably connected to the groove 15. A motor 17 is fixedly connected to the left side of the outer casing 1. A threaded screw 18 is fixedly connected to the output end of the motor 17. The threaded screw 18 is rotatably connected to the outer casing 1 and threadedly connected to the moving block 16. A transmission roller 19 is rotatably connected to the inner side of the moving frame 12. The transmission roller 19 is located on the upper and lower sides of the coating roller 13 and is provided in several places. During operation, the electrode sheet is passed through the outer casing 1. The top feed inlet is inserted into the interior of the outer casing 1, causing it to move downwards. Motor 17 drives the positive and negative thread screw 18 to rotate, which in turn moves the moving blocks 16 on both sides. The moving blocks 16 then move the moving frame 12 within the outer casing 1. The distance between the coating rollers 13 and the drive rollers 19 on both sides is adjusted according to the material and size of the electrode. As the moving frame 12 moves, it moves the inner drive roller 19, which then limits the electrode. The rotation of the drive roller 19 causes the electrode to move downwards, thus lowering it. The coating rollers 13 on both sides contact each other, and the coating operation is performed on the electrode through the liquid storage tank 14 and the coating rollers 13. This step is achieved by the motor 17 driving the positive and negative thread screws 18 to rotate. The positive and negative thread screws 18 can drive the inner moving frame 12 and the transmission roller 19 to move. The transmission roller 19 can limit the electrode and drive the electrode to move. The distance between the coating rollers 13 and the transmission rollers 19 can be adjusted so that the transmission rollers 19 and the coating rollers 13 can be adjusted according to the size of the electrode, increasing the applicable range of the coating rollers 13 for coating the electrode.

[0024] Reference Figure 1 and Figure 5 As shown, a heating box 21 is fixedly connected to the rear side of the outer casing 1, and an electric heating wire is installed inside the heating box 21. A first fan 22 is fixedly connected to the top of the heating box 21, and the air outlet of the first fan 22 is connected to the heating box 21. A ventilation hole 23 is opened inside the outer casing 1, and several ventilation holes 23 are provided. The heating box 21 is connected to the ventilation hole 23 through a connecting pipe. During operation, the heating box 21 is heated by the electric heating wire inside. The first fan 22 blows air into the interior of the outer casing 1 through the heating box 21, the connecting pipe and the ventilation hole 23, blowing hot air to both sides of the electrode sheet, so that the interior of the outer casing 1 is heated. This step can blow the hot air inside the heating box 21 to both sides of the electrode sheet through the first fan 22, so that the electrode sheet can be dried faster.

[0025] Reference Figure 1 and Figure 5 As shown, a filter box 31 is fixedly connected to the rear side of the outer casing 1, and a second fan 32 is fixedly connected to the bottom of the filter box 31. The air inlet of the second fan 32 is connected to the filter box 31, and the filter box 31 is connected to the ventilation hole 23 through a connecting pipe. During operation, the second fan 32 draws out the air inside the outer casing 1 through the filter box 31, the connecting pipe, and the ventilation hole 23. The air is filtered by passing through the filter box 31. This step, by drawing out the air inside the outer casing 1 through the second fan 32 and filtering it through the filter box 31, purifies the odor generated during coating and reduces air pollution.

[0026] Reference Figures 2 to 4 As shown, a scraper plate 41 is fixedly connected to the inner side of the movable frame 12, and the drive roller 19 is slidably connected to the scraper plate 41. The scraper plate 41 has an opening inside. During operation, when the drive roller 19 rotates, the scraper plate 41 scrapes the surface of the drive roller 19, removing residue and allowing it to fall through the opening and out through the discharge port. This step allows the scraper plate 41 to scrape away any slurry or impurities adhering to the surface of the drive roller 19, cleaning the surface and allowing impurities to fall out through the discharge port.

[0027] Reference Figures 2 to 4 As shown, several impact blocks 51 are fixedly connected to the inner side of the outer casing 1, and the impact blocks 51 are used in conjunction with the scraper plate 41. During operation, when the forward and reverse threaded screw 18 drives the moving block 16 to move the moving frame 12 away, the moving frame 12 simultaneously drives the scraper plate 41 to move. When the side of the moving frame 12 is in contact with the inner wall of the outer casing 1, the inner side of the impact block 51 contacts the outer side of the scraper plate 41 and impacts the scraper plate 41, causing impurities on the surface of the scraper plate 41 to fall off. This step, by setting several impact blocks 51, can impact the scraper plate 41 when the moving frame 12 is in contact with the inner wall of the outer casing 1, causing the scraper plate 41 to vibrate and shake off the impurities on the surface of the scraper plate 41, thereby increasing the cleanliness of the scraper plate 41 surface.

[0028] Reference Figure 1 As shown, guide rollers 61 are provided at the top and bottom of the outer casing 1, and there are several guide rollers 61. The side of the moving frame 12 is provided with a slanted cut. In this step, the electrode sheet can be placed into the interior of the outer casing 1 by the guide rollers 61 on both sides to guide the electrode sheet and prevent the electrode sheet from shifting before being placed into the interior of the outer casing 1.

[0029] Reference Figures 2 to 4 As shown, a filter screen is installed inside the ventilation hole 23; this filter screen can filter the air passing through the ventilation hole 23, reduce the dust entering the inside of the housing 1 through the ventilation hole 23, and make the inside of the housing 1 cleaner.

[0030] Reference Figure 1 As shown, a support frame is fixedly connected to the side of the outer casing 1, and the support frame is inclined; this step makes it easier to place the outer casing 1 by using the inclined support frames on the left and right sides.

[0031] Working principle: The electrode sheet is placed into the interior of the outer casing 1 through the feed port at the top of the outer casing 1, causing it to move downwards. The motor 17 drives the positive and negative thread screw 18 to rotate, which in turn drives the moving blocks 16 on both sides to move. The moving blocks 16 drive the moving frame 12 to slide inside the outer casing 1. The distance between the coating rollers 13 and the transmission rollers 19 on both sides is adjusted according to the material and size of the electrode sheet. When the moving frame 12 moves, it drives the inner transmission roller 19 to move, so that the transmission roller 19 limits the electrode sheet. The rotation of the transmission roller 19 drives the electrode sheet to move downwards, so that it contacts the coating rollers 13 on both sides. The electrode sheet is coated by the liquid storage tank 14 and the coating rollers 13. The heating box 21 is heated by the internal heating wire. The first fan 22 connects the heating box 21 and the connecting pipe. The ventilation hole 23 blows hot air into the interior of the outer casing 1, heating the interior of the outer casing 1. The second fan 32 draws out the air from the interior of the outer casing 1 through the filter box 31, connecting pipe and ventilation hole 23. The air is filtered by the filter box 31. When the drive roller 19 rotates, the scraper 41 scrapes the surface of the drive roller 19, hanging the residue on the surface of the drive roller 19 and letting it fall through the opening and then out through the outlet. When the positive and negative thread screw 18 drives the moving block 16 to move the moving frame 12 away, the moving frame 12 simultaneously drives the scraper 41 to move. When the side of the moving frame 12 is in contact with the inner wall of the outer casing 1, the inner side of the impact block 51 contacts the outer side of the scraper 41 and impacts the scraper 41, causing the impurities on the surface of the scraper 41 to fall off.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
