Description

Technical Field

[0001] This invention relates to the technical field of lithium battery processing. More specifically, this invention relates to an intelligent integrated device for producing lithium battery anode materials. Background Technology

[0002] The battery core consists of a separator, a positive electrode sheet, and a negative electrode sheet. In the current technology for producing secondary batteries, the separator, positive electrode sheet, and negative electrode sheet are first sorted manually. Then, the negative electrode sheet is put into a crusher to be crushed and the graphite is screened out. The screened graphite is then used to prepare new batteries.

[0003] To reduce feeding difficulty, existing technology sets the feed inlet of the crusher flush with the ground. During feeding, the operator only needs to use a material rake to push the negative electrode sheet into the feed inlet of the crusher, which is simple and convenient. However, the negative electrode sheet is thin and, when piled on the ground, the bottom layer of negative electrode sheet is close to the ground, making it difficult for the material rake to move the bottom layer of negative electrode sheet. As a result, the operator always needs to use both hands to pick up the bottom layer of negative electrode sheet and throw it into the crusher. This operation is cumbersome and inefficient. Furthermore, when throwing the negative electrode sheet into the crusher, the operator needs to be close to the feed inlet, which is close to the ground. If the operator falls, it will cause a serious safety accident. Summary of the Invention

[0004] To overcome the drawback of existing technologies where it is difficult to push the bottommost negative electrode sheet into the feed port of the crusher during feeding, this invention provides an intelligent integrated device for the production of lithium battery negative electrode materials.

[0005] The technical implementation scheme of the present invention is as follows:

[0006] An intelligent integrated device for producing lithium battery anode materials includes a connecting plate, a housing, and a crushing roller assembly. The housing is fixedly attached to the connecting plate. The crushing roller assembly is installed inside the housing. The device also includes a protective cover, soft rubber blocks, a receiving plate, and a post-processing component. The protective cover is detachably connected to the connecting plate and is located above the crushing roller assembly. Several soft rubber blocks are fixedly attached to the protective cover. The receiving plate is connected to the connecting plate. Several grooves are evenly spaced on the receiving plate. The post-processing component is connected to the housing and is used to regenerate the crushed anode sheets.

[0007] More preferably, the protective cover is equipped with a vacuum cleaner.

[0008] More preferably, the post-processing assembly includes a screening machine, a fine grinding mill, a mixer, and an extruder; the screening machine is connected to the outer casing; the fine grinding mill is connected to the screening machine; the mixer is connected to the fine grinding mill; and the extruder is connected to the mixer.

[0009] More preferably, the connecting plate and the receiving plate are rotatably connected.

[0010] More preferably, it also includes limit blocks; at least two limit blocks are fixedly attached to the receiving plate.

[0011] More preferably, it also includes a protective component; the protective component is connected to the connecting plate; the protective component includes a ring, a cylinder, a disk, and a spring; the ring is slidably connected to the connecting plate; the cylinder is rotatably connected to the ring, and the cylinder is fixedly connected to the receiving plate; the disk is fixedly connected to the connecting plate; at least three springs are fixedly connected between the ring and the disk; a gap is provided between the connecting plate and the receiving plate; a gap is provided between the cylinder and the disk; the lower side of the cylinder is set as a friction surface; the bottom inner side of the disk is set as a friction surface.

[0012] More preferably, it also includes a shielding component; the shielding component is connected to the connecting plate; the shielding component includes a baffle and a second spring; the baffle is slidably connected to the connecting plate, and the baffle contacts the receiving plate; at least two second springs are fixedly connected between the baffle and the connecting plate.

[0013] More preferably, it also includes a linkage block; each soft rubber block is fixedly connected to a linkage block, which is located in the corresponding groove.

[0014] More preferably, the linkage block is made of a wear-resistant material.

[0015] More preferably, the protective cover has several grids.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] First, the claw tip of the material rake can be inserted into the groove of the receiving plate, so that the position of the claw tip of the material rake is lower than the bottom negative electrode plate. This allows the material rake to smoothly push the bottom negative electrode plate into the crushing roller group, avoiding many problems caused by the inability to push the bottom negative electrode plate in the existing technology. At the same time, when the material rake is manually pushed towards the protective cover, the claw tip of the material rake forces the receiving plate to rotate, so that the material rake can smoothly push the negative electrode plate towards the protective cover. During this process, the operator does not need to deliberately adjust the standing position and the direction of force, which helps to improve the convenience of operation.

[0018] 2. When a person steps onto the receiving plate, friction is generated between the cylinder and the disc, which automatically locks the receiving plate, thus preventing the person from falling due to the rotation of the receiving plate. At the same time, during the movement of the receiving plate, the baffle can always block the gap, effectively preventing debris from flying into the gap, thus avoiding the problem of the receiving plate failing to lock due to impurities stuck in the gap.

[0019] Third, the receiving plate is used to facilitate manual pushing of the material rake to rotate. It can also be used to widen the gap between adjacent soft rubber blocks, so that the negative electrode sheet stuck in the gap between the adjacent soft rubber blocks falls to the upper part of the receiving plate and is then pushed into the crushing roller group by the material rake. No manual cleaning is required, which is very convenient. Attached Figure Description

Detailed Implementation

[0029] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0030] Example 1

[0031] A smart integrated equipment for the production of lithium battery anode materials, such as Figures 1-5 As shown, it includes a connecting plate 1, a housing 2, and a crushing roller assembly 3; the housing 2 is bolted to the connecting plate 1, and the connecting plate 1 is made of alloy material; the crushing roller assembly 3 is installed inside the housing 2; it also includes a protective cover 4, soft rubber blocks 5, a receiving plate 6, and a post-processing assembly; the protective cover 4 is fixed to the connecting plate 1, and the protective cover 4 is located above the crushing roller assembly 3; several soft rubber blocks 5 are fixed to the protective cover 4; the receiving plate 6 is connected to the connecting plate 1; several grooves 91 are equidistantly provided on the receiving plate 6; the post-processing assembly is connected to the housing 2.

[0032] A vacuum cleaner is installed on the protective cover 4 to remove the dust generated during the crushing process.

[0033] The post-processing components include a sieve 101, a fine grinding mill 102, a mixer 103, and an extruder 104; the sieve 101 is connected to the outer casing 2, through which graphite material is screened out; the fine grinding mill 102 is connected to the sieve 101, through which the screened graphite material is ground into fine powder; the mixer 103 is connected to the fine grinding mill 102; and the extruder 104 is connected to the mixer 103.

[0034] The connecting plate 1 is rotatably connected to the receiving plate 6.

[0035] It also includes limit blocks 105; two limit blocks 105 are bolted to the receiving plate 6, and the rotation angle of the receiving plate 6 is limited by the limit blocks 105.

[0036] First, the negative electrode sheets are stacked on the upper side of the receiving plate 6. During feeding, the negative electrode sheets are manually pushed to the left using a material rake. After the negative electrode sheets hit the soft rubber block 5, the soft rubber block 5 tilts to the left, allowing the negative electrode sheets to move smoothly to the inside of the protective cover 4. The negative electrode sheets are then pushed to fall from the left edge of the receiving plate 6 into the crushing roller group 3. The crushing roller group 3 crushes the negative electrode sheets. The crushed material falls into the screening machine 101, where it is screened to separate out the graphite material. The screened graphite material is fed into a fine grinding mill 102, which grinds the screened graphite material to obtain graphite powder. The fine grinding mill 102 then feeds the graphite powder into a mixer 103. At the same time, other raw materials are injected into the mixer 103 through an external conveying mechanism. The mixer 103 mixes the graphite powder and other raw materials evenly to obtain a slurry. The mixer 103 then feeds the slurry into an extruder 104, which heats and extrudes the slurry to obtain the negative electrode material.

[0037] When the material rake is manually pushed to the left, the tip of the material rake can be inserted into the groove 91 of the receiving plate 6. At this time, the tip of the material rake is lower than the bottom negative electrode, so that the material rake can smoothly push the bottom negative electrode into the crushing roller group 3, avoiding many problems caused by the inability to push the bottom negative electrode in the prior art.

[0038] When the claw tip of the material rake is inserted into the groove 91 of the receiving plate 6, and the material rake is pushed to move, the groove 91 will limit the claw tip of the material rake, causing the material rake to only move straight to the left. This means that the operator needs to adjust their position and the direction of force to push the material rake smoothly. Therefore, the receiving plate 6 is installed on the connecting plate 1 in a rotatable connection. When the claw tip of the material rake is inserted into the groove 91 of the receiving plate 6, the operator pushes the material rake towards the protective cover 4. The claw tip of the material rake forces the receiving plate 6 to rotate, so that the material rake can smoothly push the negative electrode sheet towards the protective cover 4. During this process, the operator does not need to deliberately adjust their position and the direction of force, which helps to improve the convenience of operation.

[0039] During the rotation of the receiving plate 6, the receiving plate 6 drives the limiting block 105 to perform circumferential motion. When the limiting block 105 contacts the connecting plate 1, the connecting plate 1 blocks and limits the limiting block 105, preventing the limiting block 105 from continuing to move, thereby preventing the receiving plate 6 from continuing to rotate. That is, the limiting block 105 limits the rotation angle of the receiving plate 6 to prevent the receiving plate 6 from rotating excessively.

[0040] Example 2

[0041] Based on Example 1, such as Figures 3-7 As shown, it also includes a protective component; the protective component is connected to the connecting plate 1; the protective component includes a ring 201, a cylinder 202, a disc 203, and a spring 204; the ring 201 is slidably connected to the connecting plate 1, and the ring 201 is made of alloy material; the cylinder 202 is rotatably connected to the ring 201, and the cylinder 202 is bolted to the receiving plate 6; the disc 203 is bolted to the connecting plate 1; three springs 204 are fixed between the ring 201 and the disc 203; a gap 92 is provided between the connecting plate 1 and the receiving plate 6; a gap 93 is provided between the cylinder 202 and the disc 203; the lower side of the cylinder 202 is set as a friction surface; the inner bottom of the disc 203 is set as a friction surface.

[0042] It also includes a shielding component; the shielding component is connected to the connecting plate 1; the shielding component includes a baffle 205 and a second spring 206; the baffle 205 is slidably connected to the connecting plate 1, the baffle 205 contacts the receiving plate 6, and the baffle 205 intercepts the impurities splashed in the gap 92; two second springs 206 are fixed between the baffle 205 and the connecting plate 1, and the second springs 206 are made of alloy material.

[0043] During the feeding process, a worker may step on the receiving plate 6, which is rotatably connected to the connecting plate 1. This could cause the receiving plate 6 to rotate, potentially leading to a fall and posing a significant safety hazard. When a worker steps on the receiving plate 6, it experiences downward pressure, causing the cylinder 202 to move downwards. The cylinder 202 then causes the ring 201 to slide downwards, compressing the spring 204. The cylinder 202 then contacts the disc 203. Since both the bottom of the cylinder 202 and the inner bottom of the disc 203 are designed as friction surfaces, a relative friction is generated between the cylinder 202 and the disc 203. The greater friction locks the receiving plate 6, preventing it from rotating and thus avoiding accidental falls. In normal use, the spring 204 rebounds, causing the ring 201 to move upwards. The ring 201 then moves the cylinder 202 upwards, which in turn moves the receiving plate 6 back to its original position. When the material rake is pushed towards the protective cover 4, it causes the receiving plate 6 to rotate, which in turn causes the cylinder 202 to rotate within the ring 201. During use, when someone steps onto the receiving plate 6, friction is generated between the cylinder 202 and the disc 203, automatically locking the receiving plate 6 and preventing accidental falls due to rotation.

[0044] During the locking process, both the receiving plate 6 and the cylinder 202 need to move downwards. Therefore, a gap 92 should be left between the connecting plate 1 and the receiving plate 6, and a gap 93 should be left between the cylinder 202 and the disc 203. During the crushing process, debris will fly in all directions. If this debris flies into gap 92, it will obstruct the downward movement of the receiving plate 6, preventing the cylinder 202 from pressing firmly against the disc 203. This will cause the locking of the receiving plate 6 to fail, posing a significant safety hazard. Therefore, a baffle 205 is used to block the debris flying towards gap 92, effectively preventing debris from flying into gap 92. To prevent locking failure, when the receiving plate 6 moves downward, it pushes the baffle 205 downward and stretches the spring 206. When the receiving plate 6 returns to its original position, the spring 206 rebounds and drives the baffle 205 upward back to its original position. That is, during the up-and-down movement of the receiving plate 6, the baffle 205 can always block the gap 92 to ensure the blocking effect. In use, during the movement of the receiving plate 6, the baffle 205 can always block the gap 92, effectively preventing debris from splashing into the gap 92, thus avoiding the problem of the receiving plate 6 locking failure caused by impurities stuck in the gap 92.

[0045] Example 3

[0046] Based on Example 2, such as Figure 2 and Figure 8As shown, it also includes a linkage block 207; each soft rubber block 5 is fixed with a linkage block 207, the linkage block 207 is located in the corresponding groove 91, and the linkage block 207 will move when the receiving plate 6 rotates.

[0047] The linkage block 207 is made of wear-resistant material, which helps to improve its service life.

[0048] The protective cover 4 is equipped with several grids to facilitate manual observation of the working status of the crushing roller group 3.

[0049] After prolonged use, some negative electrode sheets may become stuck in the gaps between adjacent soft rubber blocks 5, requiring manual cleaning. Therefore, when the receiving plate 6 rotates, it will move the linkage block 207, causing the linkage block 207 to rotate the soft rubber blocks 5, thereby widening the gaps between adjacent soft rubber blocks 5. This allows the negative electrode sheets stuck in the gaps between adjacent soft rubber blocks 5 to fall onto the upper side of the receiving plate 6, and then be pushed into the crushing roller group 3 by the material rake. During this process, the linkage block 207 may move to the outside of the groove 91. When the receiving plate 6 rotates back to its original position, the rebound of the soft rubber blocks 5 can drive the linkage block 207 back to the inside of the groove 91. In use, the receiving plate 6, which is used to facilitate manual pushing of the material rake for rotation, can also be used to widen the gaps between adjacent soft rubber blocks 5, allowing the negative electrode sheets stuck in the gaps between adjacent soft rubber blocks 5 to fall onto the upper side of the receiving plate 6, and then be pushed into the crushing roller group 3 by the material rake. This eliminates the need for manual cleaning and is highly convenient.
