Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulverizer technology, and in particular to a lithium battery material pulverizer. Background Technology
[0002] Lithium-ion battery material pulverizers are specialized mechanical devices designed to refine the particle size of materials involved in the production and recycling of lithium-ion batteries. Their core function is to transform various lithium-ion battery materials from their initial block, granular, or other forms into fine particles that meet the requirements of lithium-ion battery manufacturing processes through specific mechanical action.
[0003] Current lithium battery material crushers typically use a single grinding wheel to crush lithium battery materials. This single-wheel drive eliminates the need to consider the synchronous transmission between multiple grinding wheels, resulting in a simpler mechanical structure. This means the equipment is relatively easy to manufacture, with lower costs, and also facilitates later installation and commissioning. Due to its simple structure and fewer components, the probability of malfunctions during operation is relatively low.
[0004] Although the mechanical structure of a single grinding wheel is simpler, when crushing lithium battery materials, the material is only subjected to crushing force from one side, which can easily lead to uneven force distribution. This results in a wide particle size distribution after crushing, making it impossible to guarantee product consistency and quality, and increasing the workload of subsequent screening and reprocessing. Therefore, a lithium battery material crusher is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0035] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a lithium battery material crusher, including a shell 1, a connecting block 3 fixedly connected to the top of the shell 1, an opening and closing component provided inside the connecting block 3, a crushing component provided inside the shell 1, a screening component provided inside the shell 1, and a housing 4 fixedly connected to the bottom outer side of the shell 1, with a front and rear moving component provided inside the housing 4.
[0036] The crushing and grinding assembly includes two crushing rollers 16, which are rotatably connected to the inner side of a housing 1. A second drive motor 15 is fixedly connected to the outer side of the housing 1. One crushing roller 16 is fixedly connected to the output end of the second drive motor 15. A protective shell 19 is fixedly connected to the outer side of the housing 1. Two gears 20 are rotatably connected to the inner side of the protective shell 19, protecting the gears 20 from external interference. The two gears 20 are respectively fixedly connected to the outer sides of the two crushing rollers 16. After the lithium battery material enters the housing 1 through the feeding channel, the second drive motor 15 is turned on, driving one of the crushing rollers 16 to rotate. The outer sides of the two crushing rollers 16 are respectively fixed with meshing gears 20. When one crushing roller 16 rotates, the other crushing roller 16 rotates synchronously in the opposite direction through the gears 20. The two relatively rotating crushing rollers 16 crush and grind the incoming lithium battery material.
[0037] Reference Figure 2 and Figure 6The screening assembly includes multiple fixed blocks 33, all fixedly connected to the inner side of the outer casing 1. Connecting rods 29 are fixedly connected to the sides of each fixed block 33. Two connecting rods 31 are rotatably connected to the inner sides of both ends of each connecting rod 29. Connecting rods 32 are rotatably connected to the outer sides of the tops of each connecting rod 31. Connecting rods 30 are rotatably connected to the outer sides of one end of each connecting rod 32. A fixed block 26 is fixedly connected to the inner side of the outer casing 1. A dual-head motor 27 is fixedly connected to the outer side of the fixed block 26. Connecting rods 28 are rotatably connected to the outer sides of one end of each connecting rod 30. Both connecting rods 28 are fixedly connected to the output end of the dual-head motor 27. A screen plate 18 is fixedly connected to the sides of each connecting rod 32. The crushed material falls onto the screen plate 18. Then, the dual-head motor 27 is started, driving the two connecting rods 28 to rotate. Simultaneously, the rotation of connecting rods 28 drives the movement of connecting rods 30, which in turn drives the movement of connecting rods 32. Connecting rod 5 32 is rotatably connected to connecting rod 29 29 via connecting rod 4 31. Connecting rod 29 29 is fixed to fixing block 2 33, which in turn is fixed to the inside of outer casing 1. Through this series of connecting rods, connecting rod 5 32 drives the screen plate 18 to reciprocate, thus screening the material. Material that meets the particle size requirements falls through the screen plate into the collection box 17 below, while material that does not meet the requirements enters the collection bin 5 for further processing.
[0038] Reference Figure 1 , Figure 2 and Figure 3 The opening and closing assembly includes two toothed plates 13, both slidably connected to the inner side of a connecting block 3. A gear 11 is rotatably connected to the inner side of the connecting block 3, and the two toothed plates 13 are meshed with the outer side of the gear 11. A drive motor 12 is fixedly connected to the outer side of the connecting block 3, and the gear 11 is fixedly connected to the output end of the drive motor 12. Two connecting plates 10 are slidably connected to the inner sides of both ends of the connecting block 3, and the two toothed plates 13 are respectively connected to the two connecting plates 10. The operator pours lithium battery material into the feed hopper 2, and then starts the drive motor 12 to drive the gear 11 to rotate inside the connecting block 3. The rotation of the gear 11 causes the toothed plates 13 to slide relative to each other inside the connecting block 3. The toothed plates 13 are connected to the connecting plates 10, causing the connecting plates 10 to slide inside the inner sides of both ends of the connecting block 3, thereby opening or closing the feed channel. When the connecting plate 10 slides, the scrapers 9 on the inner sides of both ends of the connecting block 3 scrape off the material attached to its surface to prevent material residue from affecting the normal opening and closing of the feeding channel.
[0039] Reference Figure 1 , Figure 2 and Figure 5The forward and backward moving assembly includes two gears 22, both rotatably connected to the inside of the housing 4. Two toothed plates 25 are slidably connected to the inside of the housing 4, meshing with the outer sides of the two gears 22. A drive motor 21 is fixedly connected to the outside of the housing 4, with one gear 22 fixedly connected to the output end of the drive motor 21. Connecting blocks 23 are fixedly connected to the ends of the two toothed plates 25, and cleaning brushes 24 are fixedly connected to the outer sides of the connecting blocks 23, slidably connected to the bottom inside of the housing 1. As crushing and screening proceed, some crushed material accumulates at the bottom of the housing 1. At this time, the drive motor 21 is activated, driving one of the gears 22 to rotate inside the housing 4. The rotation of the gear 22 causes the toothed plates 25 to slide back and forth inside the housing 4. The connecting blocks 23 fixedly connected to the ends of the toothed plates 25 drive the cleaning brushes 24 fixed on the outer sides to slide back and forth on the bottom inside of the housing 1, sweeping the accumulated material to a suitable position for subsequent processing.
[0040] Reference Figure 1 , Figure 2 and Figure 3 The connecting block 3 has scrapers 9 fixedly connected to the inner sides of both ends, and two connecting plates 10 are slidably connected to the bottom of the two scrapers 9. A collection box 17 is slidably connected to the inner bottom of the outer shell 1, and a collection bin 5 is fixedly connected to the outer side of the outer shell 1. Materials meeting the particle size requirements fall into the collection box 17 through the sieve plate. When the collection box is full, it can be pulled out from the inner bottom of the outer shell 1 to transfer the material. The collection bin 5 on the outer side of the outer shell 1 is used to store unscreened materials on the sieve plate 18. Two door panels 7 are rotatably connected to the outer sides of both the outer shell 1 and the collection bin 5, and handles 6 are fixedly connected to the outer sides of multiple door panels 7. By pulling the handles 6 on the outer sides of the door panels 7, the rotatably connected door panels on the outer sides of the outer shell 1 and the collection bin 5 can be opened, facilitating inspection, cleaning, and maintenance of the equipment's interior. A feed hopper 2 is fixedly connected to the top of the connecting block 3, and two limiting inclined blocks 14 are fixedly connected to the inner side of the end of the outer shell 1. The limiting inclined blocks 14 on the inner side of the end of the outer shell 1 guide the material accurately into the space between the two grinding wheels, improving crushing efficiency. Multiple bases 8 are fixedly connected to the bottom of the outer shell 1 and the collection bin 5. By pulling the handle 6 on the outside of the door panel 7, the door panel that is rotatably connected to the outside of the outer casing 1 and the collection box 5 can be opened, making it convenient to inspect, clean and maintain the inside of the equipment.
[0041] Working principle: First, the operator pours lithium battery material into the feed hopper 2. Then, the drive motor 12 is started, driving the gear 11 to rotate inside the connecting block 3. The rotation of the gear causes the two toothed plates 13 to slide relative to or away from each other inside the connecting block 3. The toothed plates 13 are connected to the two connecting plates 10 respectively, so the sliding of the toothed plates 13 causes the connecting plates 10 to slide inside both ends of the connecting block 3. When the connecting plates 10 are open, the feeding channel is open, allowing the material to smoothly enter the housing 1. When feeding needs to be stopped, the drive motor reverses, causing the connecting plates 10 to close the feeding channel.
[0042] After the material enters the outer casing 1, the limiting inclined block 14 on the inner side of the end of the outer casing 1 guides the material, ensuring it accurately enters between the two crushing rollers and improving crushing efficiency. Then, the drive motor 15 is started to drive one of the crushing rollers 16 to rotate. When one crushing roller 16 rotates, it drives the other crushing roller 16 to rotate synchronously in the opposite direction through the transmission of gear 20. The two relatively rotating crushing rollers 16 crush and pulverize the incoming lithium battery material.
[0043] After being crushed and pulverized, the material falls onto the screen plate 18, and the dual-head motor 27 is activated, driving the two connecting rods 28 to rotate. The rotation of connecting rod 28 drives the connecting rod 30, which in turn drives the connecting rod 32. Connecting rod 32 is rotatably connected to connecting rod 29 via connecting rod 4 31, while connecting rod 29 is fixed to fixing block 33, which is fixed inside the outer casing 1. Thus, through a series of connecting rod transmissions, connecting rod 32 drives the screen plate 18 to reciprocate. The reciprocating motion of the screen plate 18 screens the material; material meeting the particle size requirements falls through the screen plate into the collection box 17 below, while material not meeting the particle size requirements is screened and enters the collection bin 5 for further processing.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
