Description

TECHNICAL FIELD

[0001] The utility model relates to lithium battery binder filter preparation technical field, more specifically, it relates to a kind of lithium battery binder filter preparation equipment. BACKGROUND

[0002] In the lithium battery binder preparation equipment technical field, there are many problems in the prior art to be solved urgently, which seriously affect the production quality of binder and equipment maintenance efficiency, mainly reflected in the following aspects:

[0003] Firstly, the existing lithium battery binder production system has obvious process defects, and most production lines lack special filtering devices. This design defect makes it impossible to effectively remove impurities and undissolved particles in the binder during production. These impurities not only affect the uniformity and stability of the binder, but also more seriously reduce its bonding performance in the lithium battery electrode preparation process. When these substandard binders are used in lithium battery production, they may cause serious quality problems such as loose electrode material bonding and shedding, ultimately affecting the overall performance and service life of the battery.

[0004] Secondly, in the equipment using filtering devices, the design of the filtering system also has significant defects. Traditional designs mostly use large-area filter plate structures. This design has exposed serious practicality problems during long-term use. Since the binder solution contains various particulate matter, the filter plate is prone to local blockage during use. As the use time increases, the blocked area gradually expands, resulting in a significant decrease in filtering efficiency. More seriously, continuous pressure may cause the filter plate to deform or break. Once this happens, the entire filter plate needs to be replaced. However, the existing whole filter plate replacement process is tedious, requiring professional disassembly tools and a long downtime, which seriously affects production efficiency and equipment maintenance efficiency.

[0005] More troublesome is that some improved equipment has added quick disassembly and assembly functions in design, trying to improve the replacement efficiency of filter plates through simplified mechanical structures. However, these improved designs still have significant defects. These quick disassembly and assembly mechanisms face serious stability problems during actual use. First, the equipment generates continuous vibrations during operation, which gradually loosens the fixed structure. Second, the pressure impact during the filtering process further exacerbates the instability of the connection parts. These factors, acting together, easily cause the filter plate to become unstable, shake, deform, or even completely fall off. The instability of the filter plate not only affects the filtering effect but also may cause binder leakage and other safety hazards, posing greater risks to production. SUMMARY

[0033] The top end of the one side of clamping block 10, the inner side of clamping groove 11 and the inner side of guide slot 12 are all designed with chamfer structure.

[0034] The inner side of clamping sleeve 6 movably has movable spring 21, the other end of movable spring 21 is connected with movable plate 22, and the one side of movable plate 22 is in contact with the top end of clamping rod 7.

[0035] The outer wall of clamping sleeve 6 is provided with reset spring 23, and one end of locking rod 18 is connected with the outer wall of clamping sleeve 6 through reset spring 23.

[0036] The linkage spring 24 is sleeved outside the linkage rod 14, one end of the linkage spring 24 is connected with the linkage sleeve 13, and the other end of the linkage spring 24 is connected with the linkage plate 16 in a contact mode.

[0037] In the embodiment, when a single filter plate is blocked, the high-pressure airflow can be used to clear the blockage directly when the filter plate is moved above the processing bin 1 due to the open design of the upper part of the processing bin 1. When the filter plate is damaged or more seriously blocked, the filter plate is first moved above the processing bin 1, then the motor 29 is stopped, then the linkage plate 16 is rotated, which drives the linkage hole 15 to rotate. When the linkage hole 15 is rotated to a position concentric with the linkage rod 14, the linkage sleeve 13 is pushed, which drives the linkage sleeve 13 to slide through the linkage hole 15. At the same time, the linkage sleeve 13 cooperates with the linkage plate 16 to extrude the linkage spring 24 sleeved outside the linkage rod 14. Then the linkage sleeve 13 no longer limits the locking rod 18. Then the clamping sleeve 6 is rotated clockwise. The clamping sleeve 6 first drives the plurality of locking rods 18 slidingly arranged on the side wall to move, and then the locking groove 17 inner wall extrudes one end of the locking rod 18. Due to the round corner design of the locking groove 17 side wall and the round corner treatment of the end of the locking rod 18, then one end of the locking rod 18 slides out of the locking groove 17 and slides into the rotating groove 19, and the other end of the locking rod 18 drives the return spring 23 to stretch. The clamping sleeve 6 drives the guide groove 12 and the clamping groove 11 inside to rotate. Due to the chamfer design of the inner wall of the clamping groove 11 and the chamfer design of one side of the clamping block 10, the inner wall of the clamping groove 11 extrudes the clamping block 10, which gradually slides out of the clamping groove 11 and gradually enters the receiving groove 8 and extrudes the push spring 9 in the receiving groove 8. When the guide groove 12 is rotated to a position corresponding to the clamping block 10, the push spring 9 is reset to push the clamping block 10 out of the receiving groove 8, and the clamping block 10 enters the guide groove 12. At the same time, the locking rod 18 moves to a position corresponding to another locking groove 17. Then the return spring 23 drives the locking rod 18 to slide and reset, so that one end of the locking rod 18 is inserted into the locking groove 17. Since the locking groove 17 is communicated with the sliding groove 20, the movable spring 21 pushes the movable plate 22 to reset, so that the movable plate 22 pushes the clamping rod 7 to slide. The clamping rod 7 drives the clamping block 10 to slide along the guide groove 12. At this time, the locking rod 18 enters the sliding groove 20. Then pull the clamping sleeve 6 and the clamping rod 7 to the two sides respectively, that is, the clamping sleeve 6 and the clamping rod 7 are removed. Then the clamping rod 7 and the clamping sleeve 6 no longer cooperate to fix and limit the filter plate. Then push the filter plate corresponding to the maintenance or replacement out of the inside of the rotating frame 5. After the maintenance and replacement of the filter plate are completed, slide the corresponding filter plate into the inside of the rotating frame 5 again. Then make the clamping rod 7 pass through the rotating frame 5 and the hole on the filter plate from one side of the rotating frame 5. Then sleeve the clamping sleeve 6 to the outside of the clamping rod 7 from the other side, and make the clamping block 10 slide into the guide groove 12 at the same time. Then the locking rod 18 will enter the sliding groove 20 again. Then one end of the clamping rod 7 pushes the movable plate 22 to move, so that the movable plate 22 extrudes the movable spring 21. When the movable spring 21 is extruded to the limit, the clamping block 10 moves to the top of the guide groove 12.And the locking rod 18 at one end of the chute 20 at the bottom of the locking slot 17, rotating the clamping sleeve 6 again, the clamping sleeve 6 drives the guide groove 12 and the clamping groove 11 and the locking rod 18 to rotate, then the locking rod 18 is extruded by the inner wall of the locking slot 17, then the locking rod 18 is slid out of the locking slot 17 and enters the rotating groove 19, and the other end of the locking rod 18 drives the return spring 23 to stretch, and the chamfered inner wall of the guide groove 12 extrudes the chamfered side of the clamping block 10, so that the clamping block 10 is retracted into the receiving groove 8 and extrudes the push spring 9. When the clamping sleeve 6 drives the clamping groove 11 to rotate to the position corresponding to the clamping block 10, the push spring 9 pushes the clamping block 10 to engage into the clamping groove 11, and the return spring 23 drives the locking rod 18 to slide and reset, so that the locking rod 18 is inserted into the corresponding locking slot 17. Then loosen the linkage sleeve 13, the linkage spring 24 pushes the linkage sleeve 13 to drive the linkage rod 14 to slide and reset, and when the linkage spring 24 is fully reset, the linkage rod 14 is no longer limited by the linkage plate 16 through the linkage hole 15. Then continue to rotate the linkage plate 16, so that the linkage plate 16 drives the linkage hole 15 to move to a position not related to the linkage rod 14, then the linkage rod 14 supports the linkage sleeve 13 through the linkage plate 16, preventing the linkage sleeve 13 from easily sliding, then the inner wall of the linkage sleeve 13 limits the outer end of the locking rod 18, so that the locking rod 18 cannot move, and the locking slot 17 cooperates with the locking rod 18 to simultaneously limit the clamping sleeve 6 and the clamping rod 7, so that the clamping sleeve 6 and the clamping rod 7 can only rotate synchronously, thereby avoiding accidental unlocking and ensuring stable fixing effect, preventing the fixing structure from loosening or even falling off, thereby ensuring stable use of the equipment.
