Description

Technical Field

[0001] The present invention relates to the field of battery material processing, and in particular to a top pressing processing mechanism for lithium battery negative electrode materials. Background Art

[0002] One of the commonly used materials for lithium battery negative electrode materials is graphite. Graphite has good conductivity, chemical stability and low electrode potential, making it an ideal negative electrode material. During the processing of graphite negative electrode materials, graphite is usually processed into a columnar structure, namely a graphite column. The preparation process of graphite columns includes multiple steps such as raw material mixing, molding, drying, and sintering. However, during these processing processes, uneven protrusions are prone to form on the outside of the graphite column. These protrusions not only affect the appearance quality of the graphite column, but also have an adverse effect on battery performance.

As the graphite column is continuously driven forward, the uneven protrusions on the outside of the graphite column can be removed. The distance between the two pressing and rotating columns and the supporting rod can be adjusted to accommodate graphite columns of different sizes.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] As described in the background art, in the prior art, when performing the protrusion removal operation on graphite columns of different sizes, it is necessary to constantly adjust the distance between the two pressing and rotating columns and the supporting rod, which is very troublesome in actual use and affects work efficiency.

[0038] In order to solve this technical problem, the present invention provides a lithium battery negative electrode material top pressing processing mechanism, which is applied to battery material processing.

[0039] Specifically, please refer to Figures 1-8As shown, the lithium battery negative electrode material pressing processing mechanism specifically includes: a processing cylinder 1, a discharge port 101 provided on the processing cylinder 1, and an adaptive clamping mechanism 2 provided in the processing cylinder 1:

[0040] The adaptive clamping mechanism 2 includes a motor 201 arranged in the processing cylinder 1, a mounting frame 202 arranged in the processing cylinder 1, a rotating disk 203 arranged on the mounting frame 202, a driving roller 204 arranged at the output end of the motor 201, a transmission roller 205 arranged at the bottom of the rotating disk 203, a conveyor belt 206 arranged on the driving roller 204 and the transmission roller 205, a guide groove 207 arranged in the processing cylinder 1, a slider 208 slidingly arranged on the guide groove 207, a spring 209 arranged on the slider 208, a fixed column 210 arranged on the slider 208, a synchronous disk 211 rotatably arranged on the processing cylinder 1, an arc groove 212 arranged on the synchronous disk 211, a push block 213 arranged on the fixed column 210, an extension column 214 arranged on the fixed column 210, and a cross block 215 arranged on the extension column 214.

[0041] The present invention provides a lithium battery negative electrode material pressing processing mechanism. In order to solve the problem in the prior art that when removing protrusions from graphite columns of different sizes, it is necessary to constantly adjust the distance between the two pressing and rotating columns and the material supporting rod, which is very troublesome in actual use and affects work efficiency, the present application provides an adaptive clamping mechanism 2, which drives the cross block 215 to adaptively clamp graphite columns of different sizes, and at the same time, realizes automatic grinding of protrusions on the surface of the graphite column, thereby improving work efficiency.

[0042] By setting the adaptive clamping mechanism 2, the cross block 215 is driven to rotate, so that the cross block 215 rotates to extrude the graphite column, thereby realizing automatic discharge of the graphite column and solving the problem of low efficiency of manual handling in the prior art;

[0043] By setting up the adaptive clamping mechanism 2, by driving the rotation of the cross block 215, the cross block 215 is rotated 90 degrees after each grinding, and different graphite columns are ground with different surfaces, so that the wear is dispersed and the service life of the cross block 215 is extended, thereby solving the problem of concentrated wear of grinding equipment in the prior art leading to short service life.

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a lithium battery negative electrode material pressing processing mechanism, wherein the two ends of a spring 209 are respectively connected to the corresponding surfaces of a slider 208 and a guide groove 207, and a fixed column 210 is slidably set on an arc groove 212;

[0048] When in use, the graphite columns are successively placed in the center of the four push blocks 213, and the elasticity of the spring 1 209 drives the slider 208, the fixed column 210 and the push block 213 to be squeezed toward the center of the processing cylinder 1, thereby squeezing and fixing the graphite columns. The graphite columns are guided by multiple push blocks 213 so that the graphite columns slide to the center of the rotating disk 203. Because the fixed column 210 and the extension column 214 are fixedly connected, when the slider 208 slides, the extension column 214 and the cross block 215 are synchronously displaced with the slider 208, and then the cross block 215 squeezes and fixes the graphite columns. Because multiple graphite columns are stacked layer by layer on the center of the four push blocks 213, through multiple graphite The gravity of the column makes the bottom graphite column and the rotating disk 203 close together. At this time, the motor 201 is started, and the motor 201 drives the driving roller 204 to rotate. Through the cooperation of the conveyor belt 206, the conveyor belt 206 drives the transmission roller 205 and the rotating disk 203 to rotate synchronously. At this time, the bottom graphite column and the rotating disk 203 rotate synchronously. The rotating graphite column and the cross block 215 cooperate to grind the protrusions on the surface of the graphite column through the cross block 215. When the size of the graphite column is replaced, the graphite columns of different sizes can be adaptively clamped in the same way. At the same time, the protrusions on the surface of the graphite column can be automatically polished, thereby improving the work efficiency. The cross block 215 is detachable.

[0049] Furthermore, a limiting column 216 is provided in the processing cylinder 1, an L-shaped rod 217 is slidably provided on the limiting column 216, a rack 218 is provided on the L-shaped rod 217, a gear 219 is rotatably provided on the extension column 214, the gear 219 and the rack 218 are adapted, a cross block 215 is rotatably provided on the extension column 214, and a discharge plate 220 is provided on the mounting frame 202, and the discharge plate 220 is adapted to the discharge port 101;

[0050] When the graphite column is polished, Figure 6As shown, by driving the L-shaped rod 217 to slide along the limiting column 216 and away from the center of the processing cylinder 1, the rack 218 and the L-shaped rod 217 slide synchronously, the rack 218 drives the gear 219 to rotate synchronously, and the gear 219 drives the cross block 215 to rotate synchronously. At this time, the two cross blocks 215 rotate in opposite directions relative to each other, and the cross blocks 215 rotate to squeeze the polished graphite column, so that the graphite column is squeezed into the middle part of the two discharge plates 220. The graphite column is discharged from the discharge port 101 through the guidance of the discharge plate 220, and then the graphite column realizes automatic discharge, wherein the discharge plate 220 is tilted on the discharge port 101, so that auxiliary discharge can be performed by the rotating rotating disk 203 to prevent the discharge port 101 from being blocked;

[0051] Furthermore, a pawl 221 is rotatably provided on the gear 219, and the pawl 221 and the rotation of the gear 219 are connected by a torsion spring. A ratchet 222 is rotatably provided on the extension column 214, and the ratchet 222 is provided on the cross block 215, and the ratchet 222 and the pawl 221 are adapted;

[0052] When the L-shaped rod 217 is driven to slide along the limiting column 216 and away from the center of the processing cylinder 1, the automatic discharge of the graphite column is realized. When the L-shaped rod 217 is driven to slide and reset, the rack 218 and the L-shaped rod 217 slide synchronously, and the rack 218 drives the gear 219 to rotate synchronously. The pawl 221 and the ratchet 222 on the gear 219 rotate idly. At this time, the cross block 215 does not rotate, and then the cross block 215 rotates 90 degrees each time it discharges. When the next graphite column is polished, the graphite column is polished through the other side of the cross block 215. By replacing different surfaces of the cross block 215 to polish different graphite columns, the wear of the cross block 215 is dispersed to multiple surfaces instead of being concentrated on a certain surface. This can extend the overall service life of the cross block 215, reduce the replacement frequency, and save costs.

[0053] Furthermore, a second spring 223 is provided on the outer side of the limiting column 216. The two ends of the second spring 223 are respectively connected to the L-shaped rod 217 and the processing cylinder 1. The second spring 223 is used to drive the L-shaped rod 217 to reset.

[0054] Furthermore, a circular groove 224 is provided on the rotating disk 203, a transmission post 225 is slidably provided on the circular groove 224, an adjustment disk 226 is provided on the transmission post 225, and a push disk 227 is rotatably provided on the transmission post 225. The end of the push disk 227 is truncated cone-shaped, and the end of the L-shaped rod 217 is wedge-shaped. The L-shaped rod 217 and the push disk 227 are adapted to each other.

[0055] like Figure 7As shown, the transmission column 225 and the transmission roller 205 are not in contact. When the rotating disk 203 rotates, the rotating disk 203 drives the transmission column 225 and the adjusting disk 226 to rotate synchronously. When the graphite column contacts the adjusting disk 226, the adjusting disk 226 drives the graphite column to rotate and move toward the bottom of the processing cylinder 1. At this time, the transmission column 225 and the driving disk 227 move downward synchronously. When the graphite column and the adjusting disk 226 move downward, the cross block 215 pre-grinds the graphite column. At the same time, the driving disk 227 moves downward and squeezes the L-shaped rod 217, so that the L-shaped rod 217 slides along the limiting column 216 and away from the center of the processing cylinder 1, thereby realizing automatic discharge. By pre-grinding the graphite column, the grinding quality of the graphite column is improved.

[0056] The adaptive clamping mechanism 2 drives the cross block 215 to adaptively clamp graphite columns of different sizes. At the same time, the protrusions on the surface of the graphite column are automatically polished. By driving the cross block 215 to rotate, automatic material discharge is achieved, thereby improving work efficiency. After each polishing, the cross block 215 rotates 90 degrees so that the other side of the cross block 215 polishes the graphite column. By replacing different surfaces of the cross block 215 to polish different graphite columns, the wear of the cross block 215 is dispersed to multiple surfaces instead of being concentrated on a certain surface. This can extend the overall service life of the cross block 215. When polishing the graphite column, the cross block 215 is used to pre-polish the graphite column to improve the polishing quality of the graphite column.

[0057] Example 2: The top pressing processing mechanism of the lithium battery negative electrode material provided in Example 1 is further optimized. Specifically, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a third spring 228 is provided on the outside of the transmission column 225, and the two ends of the third spring 228 are respectively connected to the corresponding surfaces of the adjustment disk 226 and the circular groove 224. The driving disk 227 is adapted to the transmission roller 205. The third spring 228 is used to drive the adjustment disk 226, the transmission column 225 and the driving disk 227 to reset. When the third spring 228 drives the driving disk 227 to reset, the driving disk 227 hits the transmission roller 205, causing the rotating disk 203 and the cross block 215 to vibrate, thereby separating the graphite waste adhering to the cross block 215, thereby improving the grinding quality.

[0058] Furthermore, a wedge block 1 229 is provided on the adjusting disk 226, and a wedge block 230 is provided on the circular groove 224. The wedge block 1 229 and the wedge block 230 are adapted to each other. When the adjusting disk 226 slides downward, the wedge block 1 229 and the adjusting disk 226 slide synchronously. The ends of the wedge block 1 229 and the wedge block 230 are both wedge-shaped. Through the cooperation of the wedge block 1 229 and the wedge block 230, the adjusting disk 226 and the rotating disk 203 are overlapped, and the friction between the adjusting disk 226 and the rotating disk 203 is improved.

[0059] Furthermore, an adjustment block 231 is provided on the rack 218 , and the adjustment block 231 is slidably provided on the L-shaped rod 217 ;

[0060] Furthermore, a driving groove 232 is provided on the L-shaped rod 217, and a ball 233 is slidably provided on the driving groove 232. A spring 234 is connected to the ball 233 and the driving groove 232. A clamping groove 235 is provided on the adjustment block 231. The ball 233 and the clamping groove 235 are adapted to each other. When replacing graphite columns of different sizes, the push block 213, the fixed column 210, the extension column 214, the gear 219, the slider 208 and the cross block 215 slide synchronously. The gear 219 drives the rack 218 to slide synchronously, and the rack 218 drives the adjustment block 231 to slide. Then, through the adaptation of the ball 233 and the clamping groove 235, the adjustment block 231 is limited. In this way, the distance of each sliding of the L-shaped rod 217 is the same, and the angle of each rotation of the cross block 215 is 90 degrees.

[0061] The use process of the lithium battery negative electrode material pressing processing mechanism provided by the present invention is as follows:

[0062] When in use, the graphite columns are successively placed in the center of the four ejecting blocks 213, and the elasticity of the spring 1 209 drives the slider 208, the fixed column 210 and the ejecting block 213 to be squeezed toward the center of the processing cylinder 1, thereby squeezing and fixing the graphite columns. The graphite columns are guided by the multiple ejecting blocks 213 so that the graphite columns slide to the center of the rotating disk 203. Since the fixed column 210 and the extension column 214 are fixedly connected, when the slider 208 slides, the extension column 214 and the cross block 215 are displaced synchronously with the slider 208, thereby squeezing and fixing the graphite columns by the cross block 215. Since multiple graphite columns are stacked layer by layer in the center of the four ejecting blocks 213, the motor 201 is started at this time, and the electric The machine 201 drives the driving roller 204 to rotate. Through the cooperation of the conveyor belt 206, the conveyor belt 206 drives the transmission roller 205 and the rotating disk 203 to rotate synchronously. At this time, the graphite column at the bottom and the rotating disk 203 rotate synchronously, so that the graphite column at the bottom and the adjusting disk 226 are in close contact. The rotating disk 203 drives the transmission column 225 and the adjusting disk 226 to rotate synchronously. The adjusting disk 226 drives the graphite column to rotate and move toward the bottom of the processing cylinder 1. At this time, the transmission column 225 and the top disk 227 move downward synchronously. When the graphite column and the adjusting disk 226 move downward, the cross block 215 pre-grinds the graphite column. At the same time, the top disk 227 moves downward and squeezes the L-shaped rod 217, so that the L-shaped rod 217 moves along the limit column 216 and moves away from the processing cylinder 1. The adjusting block 231, the rack 218 and the L-shaped rod 217 slide synchronously, the rack 218 drives the gear 219 to rotate synchronously, the pawl 221 on the gear 219 drives the ratchet 222 to rotate synchronously, and the ratchet 222 drives the cross block 215 to rotate synchronously. At this time, the two cross blocks 215 rotate in opposite directions relative to each other. The cross block 215 rotates to extrude the polished graphite column so that the graphite column is squeezed into the middle part of the two discharge plates 220. The graphite column is discharged from the discharge port 101 through the guidance of the discharge plate 220, and then the graphite column realizes automatic discharge, wherein the discharge plate 220 is tilted on the discharge port 101, so that auxiliary discharge can be performed by rotating the rotating disk 203. After the graphite column is discharged, the spring The third spring 228 drives the adjusting plate 226 and the pushing plate 227 to reset. At this time, the L-shaped rod 217 is reset by the elasticity of the second spring 223, and the rack 218 and the L-shaped rod 217 slide synchronously. The rack 218 drives the gear 219 to rotate synchronously, and the pawl 221 and the ratchet 222 on the gear 219 rotate idly. At this time, the cross block 215 does not rotate, and then the cross block 215 rotates 90 degrees each time the material is discharged. When the next graphite column is polished, the graphite column is polished through the other side of the cross block 215. By changing different surfaces of the cross block 215 to polish different graphite columns, the wear of the cross block 215 is dispersed to multiple surfaces instead of being concentrated on a certain surface, which can extend the overall service life of the cross block 215.
