Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery processing technology, specifically to a lithium-ion battery homogenizing and stirring device. Background Technology

[0002] A lithium-ion battery slurry mixing device is a piece of equipment used for the preparation of lithium-ion battery electrode slurry. Its main function is to mix, dissolve and disperse raw materials such as binders, conductive agents and positive electrode materials to form a uniform slurry for subsequent coating processes.

[0003] However, existing lithium-ion battery slurry mixing devices require operators to place the lithium-ion battery raw materials inside the mixing tank and then stir them using a stirring rod. Since the stirring rod rotates in the same direction, it cannot evenly disperse the raw material particles throughout the mixing tank, resulting in a low processing rate. Furthermore, most mixing devices generate and trap air bubbles during processing. These bubbles typically escape naturally through the vent, but the escape is slow and difficult to remove promptly. This trapped air not only reduces the uniformity of the slurry but also affects the processing quality of the lithium-ion batteries. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a lithium-ion battery homogenizing and mixing device includes a mixing tank 1, which allows lithium-ion batteries to be processed inside. The top of the mixing tank 1 has a feed inlet 2, allowing workers to add lithium-ion battery raw materials into the mixing tank 1. The bottom of the mixing tank 1 has a discharge outlet 3, which discharges the processed material from the mixing tank 1. The top of the mixing tank 1 is connected to an exhaust port 4, which removes air bubbles generated during processing inside the mixing tank 1. A stepper motor 5 is bolted to the top of the mixing tank 1, and a rotating mechanism 6 is provided on one side of the stepper motor 5. Under the action of the rotating mechanism 6, the first stirring rod 7 is rotatably connected to the inner cavity of the mixing tank 1, and the second stirring rod 8 is rotatably connected to the inner cavity of the first stirring rod 7. The bottom of the second stirring rod 8 is rotatably connected to the inner cavity of the mixing tank 1. Under the action of the rotating mechanism 6, the first stirring rod 7 and the second stirring rod 8 can rotate simultaneously in opposite directions, which speeds up the stirring rate of lithium-ion battery raw materials and improves the practicality of the device. A transmission rod 9 is driven and connected to one side of the stepper motor 5. Under the action of the stepper motor 5, the transmission rod 9 can rotate. A fixing sleeve 10 is bolted to the surface of the mixing tank 1. The inner cavity of the fixed sleeve 10 is rotatably connected to the surface of the transmission rod 9. Under the action of the fixed sleeve 10, the positional deviation of the transmission rod 9 during operation is effectively prevented, increasing the stability of the transmission rod 9 and thus improving the stability of the device. A rotating block 11 is drivenly connected to the bottom of the transmission rod 9. The surface of the rotating block 11 is rotatably connected to the bottom of the mixing tank 1. A corresponding plate 12 is slidably connected to the surface of the rotating block 11. Under the action of the transmission rod 9, the rotating block 11 can rotate at the bottom of the mixing tank 1, and with the cooperation of the corresponding plate 12, the rotating block 11 can drive the mixing tank 1 to vibrate on the top of the corresponding plate 12. This accelerates the rate of bubble discharge, thereby improving the practicality of the device. A mounting shell 14 is bolted to the surface of the corresponding plate 12, and a fixing rod 13 is bolted to the surface of the mounting shell 14. One side of the fixing rod 13 is slidably connected to one end of the rotating block 11. Under the action of the fixing rod 13, the positional deviation of the rotating block 11 during operation is effectively reduced, thereby improving the stability of the device. A guide mechanism 15 is provided in the inner cavity of the mounting shell 14. Under the action of the guide mechanism 15, the mixing tank 1 can be guided, effectively reducing the positional deviation of the mixing tank 1 when it moves up and down, thereby improving the stability of the device.

[0023] The rotating mechanism 6 includes a first bevel gear 61, one side of which is fixedly connected to the output shaft of the stepper motor 5. A second bevel gear 62 meshes with one side of the first bevel gear 61. The top of the second bevel gear 62 is connected to the top of the transmission rod 9 via two pulleys and a timing belt. A third bevel gear 63 meshes with the other side of the first bevel gear 61. The surface of the second bevel gear 62 is fixedly connected to the top of the second stirring rod 8, and the bottom of the third bevel gear 63 is fixedly connected to the top of the first stirring rod 7. The second bevel gear 62 and the third bevel gear 63 are the same size and are symmetrically designed about the central axis of the first bevel gear 61. With the cooperation of the stepper motor 5 and the first bevel gear 61, the second bevel gear 62 can drive the second stirring rod 8 to rotate, while the third bevel gear 63 drives the first stirring rod 7 to rotate in the opposite direction, which speeds up the stirring rate of lithium-ion battery raw materials and improves the practicality of the device.

[0024] The guiding mechanism 15 includes a sliding block 151. One side of the sliding block 151 is fixedly connected to the surface of the mixing tank 1. A tension spring 152 is fixedly connected to the bottom of the sliding block 151. The bottom of the tension spring 152 is fixedly connected to the inner cavity of the mounting shell 14. A guide rod 153 is slidably connected to the inner cavity of the sliding block 151. The bottom of the guide rod 153 is bolted to the inner cavity of the mounting shell 14. With the cooperation of the rotating block 11 and the corresponding plate 12, the mixing tank 1 can drive the sliding block 151 to move up and down on the surface of the guide rod 153. Under the action of the tension spring 152, the mixing tank 1 can achieve a vibration effect, which can accelerate the rise of bubbles, the deformation and breakage of bubbles, and avoid the remixing of bubbles, thereby reducing the accumulation of bubbles inside the mixing tank 1 and improving the practicality of the device.

[0025] Working principle: First, the operator puts the lithium-ion battery raw materials to be processed into the mixing tank 1 through the feed inlet 2. With the cooperation of the stepper motor 5 and the first bevel gear 61, the second bevel gear 62 drives the second stirring rod 8 to rotate inside the mixing tank 1. Simultaneously, the third bevel gear 63 drives the first stirring rod 7 to rotate in the opposite direction inside the mixing tank 1. At the same time, the second bevel gear 62 rotates the transmission rod 9 through two pulleys and a timing belt. The transmission rod 9 drives the rotating block 11 to rotate at the bottom of the mixing tank 1. When the longer part of the rotating block 11 contacts the top of the corresponding plate 12, the rotating block 11... 1. The mixing tank 1 moves upward, and at the same time, the mixing tank 1 moves the sliding block 151 on the surface of the guide rod 153, which allows the tension spring 152 to be stretched. When the longer part of the rotating block 11 intersects with the surface of the corresponding plate 12, the sliding block 151 can be driven by the tension spring 152 to return the mixing tank 1 to its original position, thereby achieving the vibration effect of the mixing tank 1. One end of the rotating block 11 slides in the inner cavity of the fixed rod 13, which makes the rotating block 11 work more stably on the top of the corresponding plate 12. After the lithium-ion battery raw materials inside the mixing tank 1 are processed, the staff can discharge the materials through the discharge port 3.
