Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and more specifically, to an intelligent integrated device for producing negative electrode materials for lithium batteries. Background Art

[0002] The battery core is composed of a separator, a positive electrode sheet and a negative electrode sheet. When producing secondary batteries in the prior art, the separator, the positive electrode sheet and the negative electrode sheet are first manually sorted, and then the negative electrode sheet is put into a crusher for crushing, and the graphite therein is screened out, and then a new battery is prepared using the screened graphite;

[0003] In order to reduce the difficulty of feeding, the existing technology will set the feeding port of the crusher flush with the ground. When feeding, the human only needs to use a material rake to push the negative electrode sheets into the feeding port of the crusher. The operation is simple and convenient. However, the negative electrode sheets are in the form of thin sheets. After they are stacked on the ground, the negative electrode sheets at the bottom layer are close to the ground, which makes it difficult for the material rake to push the negative electrode sheets at the bottom layer to move. As a result, the human always needs to use both hands to pick up the negative electrode sheets at the bottom layer and throw them into the crusher. The operation is cumbersome and inefficient. In addition, when the human throws the negative electrode sheets into the crusher, it needs to be close to its feeding port, and the crusher feeding port is close to the ground. Once the human falls, a major safety accident will occur. Summary of the invention

[0004] In order to overcome the shortcoming of the prior art that it is difficult to push the bottom negative electrode sheet into the crusher feeding port during feeding, the present invention provides an intelligent integrated equipment for producing negative electrode materials for lithium batteries.

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

[0006] An intelligent integrated equipment for producing negative electrode materials for lithium batteries, comprising a connecting plate, an outer shell and a crushing roller group; the outer shell is fixedly connected to the connecting plate; the crushing roller group is installed on the inner side of the outer shell; it also includes a protective cover, a soft rubber block, a receiving plate and a post-processing component; the protective cover is detachably connected to the connecting plate, and the protective cover is located above the crushing roller group; a plurality of soft rubber blocks are fixedly connected to the protective cover; the receiving plate is connected to the connecting plate; a plurality of grooves are equidistantly provided on the receiving plate; the post-processing component is connected to the outer shell, and the post-processing component is used to regenerate the crushed negative electrode sheets.

[0012] More preferably, it also includes a shielding assembly; the shielding assembly is connected to the connecting plate; the shielding assembly includes a baffle and two springs; the baffle is slidably connected to the connecting plate, and the baffle is in contact with the receiving plate; at least two two springs are fixed between the baffle and the connecting plate.

[0013] More preferably, a linkage block is further included; each soft rubber block is fixedly connected with a linkage block, and the linkage block is located in the corresponding groove.

[0015] More preferably, a plurality of grids are provided on the protective cover.

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

[0017] 1. The claw tip of the material rake can be inserted into the groove of the receiving plate, so that the claw tip of the material rake is lower than the negative electrode sheet of the lowest layer, so that the material rake can smoothly push the negative electrode sheet of the lowest layer into the crushing roller group, avoiding many problems caused by the inability to push the negative electrode sheet of the lowest layer to move in the prior art. At the same time, when the material rake is manually pushed to move toward 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 sheet toward the protective cover. In this process, there is no need for manual adjustment of the position and force direction, which is conducive to improving the convenience of operation;

[0018] Second, when a person steps on the receiving plate, friction will be generated between the cylinder and the disc, automatically locking the receiving plate, thereby avoiding the problem of a person falling due to the rotation of the receiving plate.

DETAILED DESCRIPTION

[0029] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0030] Example 1

[0031] An intelligent integrated equipment for producing negative electrode materials for lithium batteries, such as Figure 1-Figure 5 As shown, it includes a connecting plate 1, an outer shell 2 and a crushing roller group 3; the outer shell 2 is bolted to the connecting plate 1, and the connecting plate 1 is set to an alloy material; the crushing roller group 3 is installed on the inner side of the outer shell 2; it also includes a protective cover 4, a soft rubber block 5, a receiving plate 6 and a post-processing component; the protective cover 4 is fixedly connected to the connecting plate 1, and the protective cover 4 is located above the crushing roller group 3; a number of soft rubber blocks 5 are fixedly connected to the protective cover 4; the receiving plate 6 is connected to the connecting plate 1; a number of grooves 91 are equidistantly provided on the receiving plate 6; the shell 2 is connected to the post-processing component.

[0032] A vacuum cleaner is provided on the protective cover 4, and the dust generated during the crushing process is sucked away by the vacuum cleaner.

[0033] The post-processing components include a sieving machine 101, a fine grinder 102, a mixer 103 and an extruder 104; the sieving machine 101 is connected to the outer shell 2, and the graphite material is screened out by the sieving machine 101; the fine grinder 102 is connected to the sieving machine 101, and the screened graphite material is ground into fine powder by the fine grinder 102; the fine grinder 102 is connected to the mixer 103; and the mixer 104 is connected to the extruder 104.

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

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

[0036] First, the negative electrode sheets are stacked on the upper side of the receiving plate 6. When 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, so that the negative electrode sheets move smoothly to the inside of the protective cover 4. The negative electrode sheets are continuously pushed to move, so that the negative electrode sheets fall from the left edge of the receiving plate 6 to the crushing roller group 3. The crushed negative electrode sheets are crushed by the crushing roller group 3. The crushed materials fall into the sieving machine 101. The sieving machine 101 screens the crushed materials, and the graphite materials therein are screened out, and the graphite materials are The screened graphite material is conveyed to the fine grinder 102, and the fine grinder 102 grinds the screened graphite material to obtain graphite powder. Then the fine grinder 102 conveys the graphite powder to the mixer 103. At the same time, other raw materials are injected into the mixer 103 through an external conveying mechanism. The graphite powder and other raw materials are evenly mixed by the mixer 103 to obtain a mixture slurry. Then the mixer 103 conveys the mixture slurry to the extruder 104, and the extruder 104 heats and extrude the mixture slurry to obtain a negative electrode material.

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

[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, which requires manual adjustment of the position and the direction of force in order to smoothly push the material rake to move. Therefore, the receiving plate 6 is installed on the connecting plate 1 in a rotating connection manner. When the claw tip of the material rake is inserted into the groove 91 of the receiving plate 6, the material rake is manually pushed to move toward 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 toward the protective cover 4. In this process, there is no need for manual adjustment of the position and the direction of force, which is conducive to improving the convenience of operation.

[0039] During the rotation of the receiving plate 6, the receiving plate 6 drives the limit block 105 to perform circular motion. When the limit block 105 contacts the connecting plate 1, the connecting plate 1 blocks the limit block 105, so that the limit block 105 cannot continue to move, thereby preventing the receiving plate 6 from continuing to rotate. That is, the rotation angle of the receiving plate 6 is limited by the limit block 105 to prevent the receiving plate 6 from excessive rotation.

[0040] Example 2

[0041] On the basis of Example 1, Figure 3-Figure 7 As shown, it also includes a protection component; the protection component is connected to the connecting plate 1; the protection component includes a ring 201, a cylinder 202, a disk 203 and a spring 204; the connecting plate 1 is slidably connected with the ring 201, and the ring 201 is set to an alloy material; the ring 201 is rotatably connected with the cylinder 202, and the cylinder 202 is bolted to the receiving plate 6; the disk 203 is bolted to the connecting plate 1; three springs 204 are fixedly connected between the ring 201 and the disk 203; a gap 92 is set between the connecting plate 1 and the receiving plate 6; a gap 93 is set between the cylinder 202 and the disk 203; the lower side of the cylinder 202 is set as a friction surface; the inner bottom of the disk 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 spring 206; the baffle 205 is slidably connected to the connecting plate 1, the baffle 205 is in contact with the receiving plate 6, and the impurities splashing from the gap 92 are intercepted by the baffle 205; two springs 206 are fixedly connected between the baffle 205 and the connecting plate 1, and the spring 206 is set to an alloy material.

[0043] During the feeding process, a person may step on the receiving plate 6, and the receiving plate 6 is connected to the connecting plate 1 in a rotatable manner, so that the receiving plate 6 rotates, which may cause the person to fall, posing a great safety hazard. Therefore, after the person steps on the receiving plate 6, the receiving plate 6 is subjected to downward pressure, so that the receiving plate 6 drives the cylinder 202 to move downward, and the cylinder 202 drives the ring 201 to slide downward, and the ring 201 compresses the spring 204, and the cylinder 202 moves downward and contacts the disc 203. Since the bottom of the cylinder 202 and the inner bottom of the disc 203 are both set as friction surfaces, a relative friction is generated between the cylinder 202 and the disc 203. The larger friction force will lock the receiving plate 6 to prevent the receiving plate 6 from rotating, thereby preventing people from falling. During normal use, the spring 204 rebounds and drives the ring 201 to move upward, the ring 201 drives the cylinder 202 to move upward, the cylinder 202 drives the receiving plate 6 to move upward back to its original position, and the material rake is manually pushed to move toward the protective cover 4, so that the material rake drives the receiving plate 6 to rotate, and the receiving plate 6 drives the cylinder 202 to rotate in the ring 201. During use, after manually stepping on the receiving plate 6, friction will be generated between the cylinder 202 and the disc 203, automatically locking the receiving plate 6, thereby avoiding the problem of people falling due to the rotation of the receiving plate 6.

[0044] During the locking process, both the receiving plate 6 and the cylinder 202 need to move downward, that is, a gap 92 should be reserved between the connecting plate 1 and the receiving plate 6, and a gap 93 should be reserved between the cylinder 202 and the disc 203. During the crushing process, debris will be generated in all directions. If the debris splashes into the gap 92, it will block the receiving plate 6 moving downward, so that the cylinder 202 cannot be pressed against the disc 203, resulting in the failure of the locking of the receiving plate 6, which poses a great safety hazard. Therefore, the debris splashing into the gap 92 is blocked by the baffle 205 to effectively prevent the debris from splashing into the gap 92. , thereby avoiding locking failure. When the receiving plate 6 moves downward, the receiving plate 6 pushes the baffle 205 to move downward and stretches the spring 206. When the receiving plate 6 moves back to its original position, the spring 206 rebounds and drives the baffle 205 to move 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 1 92 to ensure the shielding effect. When in use, during the movement of the receiving plate 6, the baffle 205 can always block the gap 1 92, effectively preventing debris from splashing into the gap 1 92, thereby avoiding the problem of locking failure of the receiving plate 6 due to impurities stuck in the gap 1 92.

[0045] Example 3

[0046] On the basis of Example 2, Figure 2 and Figure 8As shown, a linkage block 207 is also included; each soft rubber block 5 is fixed with a linkage block 207, and the linkage block 207 is located in the corresponding groove 91. When the receiving plate 6 rotates, the linkage block 207 will be moved.

[0047] The linkage block 207 is made of a wear-resistant material, which is beneficial to increasing the service life.

[0048] A plurality of grids are arranged on the protective cover 4 to facilitate manual observation of the working status of the crushing roller group 3 .

[0049] After long-term use, some negative electrode sheets will be stuck in the gaps of adjacent soft rubber blocks 5 and need to be cleaned manually. Therefore, when the receiving plate 6 rotates, the receiving plate 6 will toggle the linkage block 207 to move, so that the linkage block 207 drives the soft rubber block 5 to twist, thereby expanding the gaps of adjacent soft rubber blocks 5, so that the negative electrode sheets stuck in the gaps of adjacent soft rubber blocks 5 fall to the upper side of the receiving plate 6, and are then pushed into the crushing roller group 3 together with 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 block 5 can drive the linkage block 207 to move back to the inside of the groove 91. When in use, the receiving plate 6 that is rotated to facilitate manual pushing of the material rake can also be used to expand the gaps of adjacent soft rubber blocks 5, so that the negative electrode sheets stuck in the gaps of adjacent soft rubber blocks 5 fall to the upper side of the receiving plate 6, and are then pushed into the crushing roller group 3 together with the material rake. No manual cleaning is required, and it is very convenient.
