[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1

[0022] The utility model provides a lithium battery electrode slurry spraying machine, such as Figure 1-6 As shown, it includes a box body 1, a feed port 2 is opened on the top of one side of the box body 1, a discharge port 3 is opened on the bottom of one side of the box body 1, and the discharge port 3 is at the bottom end of the feed port 2. A round rod 4 is fixedly installed on one side of the interior of the box body 1, and an electrode foil roller 5 is movably sleeved on the outer wall of the round rod 4. The outer wall of the electrode foil roller 5 is rotatably connected to the electrode foil 6, and the bottom end of the electrode foil 6 is in contact with the outer wall of the electrode foil roller 5. An L-shaped plate 7 is fixedly installed on the top of the inner wall of the box body 1, and the number of the L-shaped plates 7 is two, and the opposite surfaces of the two L-shaped plates 7 are in contact with the two sides of the electrode foil 6.

[0023] A feed port 2 is provided at the top of one side of the box body 1. After the electrode foil 6 enters the box body 1 through the feed port 2, the electrode foil 6 is taken out of the discharge port 3 at the bottom end of the feed port 2 around the electrode foil roller 5, so that the bottom end of the electrode foil 6 is attached to the outer wall of the electrode foil roller 5. The electrode foil roller 5 is movably sleeved on the outer wall of the round rod 4 fixedly installed inside the box body 1 to rotate the electrode foil roller 5. When the electrode foil 6 is extracted from the discharge port 3, the electrode foil 6 is extracted after being sprayed on the surface of the electrode foil 6 by the rotating electrode foil roller 5, so that the sprayed electrode foil 6 can be taken out more quickly.

[0024] like Figure 1-3As shown, a partition 8 is fixedly installed on the top of the front end of the outer wall of the box body 1, and a motor 9 is fixedly installed on the top of the partition 8. A groove 10 is opened on the top of the outer wall of the box body 1, and the output end of the motor 9 passes through the outer wall of the box body 1 and extends to the inside of the groove 10 where a gear 11 is fixedly installed. A rack 12 is meshed and connected on one side of the gear 11, and a fixing bracket 13 is movably sleeved on the outer side of the rack 12. There are two fixing brackets 13, and the two fixing brackets 13 are movably sleeved on the middle and bottom of the outer wall of the rack 12 respectively, and the other ends of the fixing brackets 13 are fixedly installed on the inner wall of the groove 10, a long plate 14 is fixedly installed on the top of the rack 12, a pressure plate 15 is fixedly installed on the bottom end of the long plate 14, and a telescopic rod 16 is fixedly installed on the bottom of the other end of the long plate 14.

[0025] By starting the motor 9 at the top of the partition 8, the gear 11 fixedly installed at the output end of the motor 9 rotates, thereby driving the rack 12 meshed with the gear 11 to move up and down. The rack 12 is limited by the fixing frame 13 while moving up and down to prevent it from falling off. The rack 12 moves up and down, thereby driving the long board 14 fixedly installed at the top of the rack 12 to move upward. At the same time, the telescopic rod 16 fixed at the bottom of the other end of the long board 14 is driven to stretch up and down at the same time. When the long board 14 moves upward to the top, it can be more After the electrode foil 6 enters the box body 1 through the feed port 2, the electrode foil 6 is taken out of the discharge port 3 at the bottom end of the feed port 2 around the electrode foil roller 5. After the electrode foil 6 is placed, the motor 9 is reversed to drive the pressing plate 15 fixed at the bottom end of the long plate 14 to move downward through the rack 12 and the telescopic rod 16. When the bottom end of the pressing plate 15 fits with the surface of the electrode foil 6, the sprayed electrode foil 6 can be better slightly smeared, so that the thickness of the slurry on the surface of the electrode foil 6 is more uniform, so that the slurry can be quickly solidified and formed on the surface of the electrode foil 6.

[0026] like Figure 4-6 As shown, L-shaped frames 17 are fixedly installed on the top of both sides of the box body 1 near the electrode foil 6, and an annular ring 18 is fixedly installed on the top of one side of the L-shaped frame 17. A water pipe 19 is inserted into the annular ring 18. The two annular rings 18 are respectively sleeved on the outer walls of both ends of the water pipe 19. A plurality of nozzles 20 are fixedly installed on the bottom end of the outer wall of the water pipe 19. A liquid extraction pipe 21 is fixedly installed at the center of the other end of the water pipe 19. A material storage barrel 22 is fixedly installed on the other end of the liquid extraction pipe 21, and a material extraction pump 23 is fixedly installed on the outer wall of the liquid extraction pipe 21.

[0027] By starting the extraction pump 23, the extraction pipe 21 extracts the slurry from the storage tank into the water pipe 19 fixedly sleeved by the annular ring 18, and the surface of the electrode foil 6 is sprayed through multiple nozzles 20 fixedly installed at the bottom of the water pipe 19. During spraying, the L-shaped plates 7 fixedly installed on both sides of the opposite surfaces inside the box 1 are fitted with both sides of the electrode foil 6, thereby blocking the slurry sprayed on the electrode foil 6, reducing the loss of slurry, and thus being able to better and more evenly spray the electrode foil 6, thereby improving work efficiency.

[0028] like Figure 2 As shown, silicone pads are fixedly installed on one side of the opposite surfaces of the two L-shaped plates 7. The silicone pads can better protect the two sides of the L-shaped plates 7 that are in contact with the electrode foil 6, thereby preventing the two sides of the electrode foil 6 from being damaged by friction. It can also better block the slurry sprayed on the electrode foil 6 and reduce the loss of slurry. The bottom end of the pressing plate 15 is fixedly installed with a silicone pad, thereby protecting the surface of the electrode foil 6 when it is lightly smeared, so that the water pipe 19 can evenly spray the electrode foil 6 and then lightly smear the electrode foil 6, so that the thickness of the slurry on the surface of the electrode foil 6 is more uniform.

[0029] Working principle: When using the box 1, start the motor 9 at the top of the partition 8 to rotate the gear 11 fixed at the output end of the motor 9, thereby driving the rack 12 meshing with the gear 11 to move up and down, and the rack 12 is limited and fixed by the fixing frame 13 while moving up and down to prevent it from falling off. The rack 12 moves up and down, thereby driving the long plate 14 fixed at the top of the rack 12 to move upward, while driving the telescopic rod 16 fixed at the bottom of the other end of the long plate 14 to extend and retract up and down at the same time. When the long plate 14 moves upward to the top, the electrode foil 6 is passed through the feed port 2 into the box 1, and the electrode foil 6 is taken out of the discharge port 3 at the bottom of the feed port 2 around the electrode foil roller 5, so that the bottom end of the electrode foil 6 is attached to the outer wall of the electrode foil roller 5, and the electrode foil roller 5 is rotated and sleeved on the outer wall of the round rod 4 fixedly installed inside the box 1, so that the electrode foil roller 5 drives the electrode foil 6 to rotate. After the electrode foil 6 is placed, the motor 9 is reversed to drive the pressing plate 15 fixed at the bottom end of the long plate 14 to move downward through the rack 12 and the telescopic rod 16. When the bottom end of the pressing plate 15 is in contact with the surface of the electrode foil 6, the sprayed electrode foil 6 can be slightly smeared, so that the thickness of the slurry on the surface of the electrode foil 6 is more uniform, so that the slurry is quickly solidified on the surface of the electrode foil 6. The motor 9 is turned off and the material pump 23 is started. The slurry is pumped from the storage tank into the water pipe 19 fixedly sleeved by the annular ring 18 through the liquid pumping pipe 21. The surface of the electrode foil 6 is sprayed through multiple nozzles 20 fixedly installed at the bottom end of the water pipe 19. During spraying, the L-shaped plates 7 fixedly installed on both sides of the opposite surfaces of the inside of the box 1 are in contact with both sides of the electrode foil 6, thereby blocking the slurry sprayed on the electrode foil 6 and reducing the loss of slurry. This allows the electrode foil 6 to be better sprayed evenly, thereby improving work efficiency.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
