A quick release assembly is mounted at the bottom end of the transmission shaft; fixing rods are fixed to the two ends, deviating from each other, of the two sliding blocks. Fixing holes are formed in the outer walls of the connecting frames, and the fixing rods penetrate through the fixing holes; when the grinding disc needs to be maintained, the sliding blocks on the two sides can synchronously and relatively move only by pushing the shifting rod. The sliding block can drive the fixing rod to be separated from the fixing hole in the moving process, and once the fixing rod is completely separated, limitation between the box body and the connecting frame is relieved. At the moment, a worker can quickly detach the grinding disc, the whole process is simple, convenient and quick, and time and labor cost are greatly saved. And in the mounting link, the mounting between the transmission shaft and the grinding disc can be quickly completed only by quickly inserting the fixing rods into the fixing holes, and stable and reliable connection is quickly established.

Description

Technical Field

[0001] This utility model relates to the field of conductive agent processing technology, specifically to a grinding disc structure for grinding conductive agents. Background Technology

[0002] In fields such as new energy materials and electronic devices, the uniform dispersion of conductive agents (such as carbon black and graphene) is crucial for improving the conductivity of materials. To optimize the interfacial bonding between the conductive agent and the matrix material, grinding processes are indispensable. Grinding equipment (such as ball mills and sand mills) achieves nanoscale dispersion through mechanical shearing and collision, and the material and structural design of the grinding disc directly affect grinding efficiency and product quality.

[0003] Currently, in various grinding equipment, the grinding disc and the transmission structure (drive shaft) are mostly connected and fixed by key or flange bolts. For example, the utility model patent with authorization announcement number CN202420057671.0 discloses a grinding and dispersing device for lithium-ion battery conductive agents. This device includes a dispersion box, a drive motor at the top of the dispersion box, a feeding cylinder inside the dispersion box, a feed pipe at the top of the feeding cylinder, one end of the feed pipe extending through the dispersion box to the top of the feeding cylinder, a first drive wheel connected to the output shaft of the drive motor, a first rotating frame matching the first drive wheel on the outside of the feeding cylinder, a second rotating frame at the bottom of the feeding cylinder, and a grinding head at the bottom of the feeding cylinder. By incorporating a feeding cylinder, the raw material is poured into the feeding cylinder through the feed pipe during the grinding of the conductive agent. The raw material is then fed into the grinding tank through the feeding pipe on the feeding cylinder. As the feeding cylinder rotates, the conductive agent is ground and dispersed by the grinding head in conjunction with the grinding tank. This facilitates feeding and improves grinding efficiency.

[0004] Although this lithium-ion battery conductive agent grinding and dispersing device improves grinding efficiency, the grinding head and feed cylinder use conventional connection methods. While these existing connection methods ensure connection strength, they suffer from significant problems with inconvenient assembly and disassembly. For keyed connections, disassembly requires hammering or hydraulic ejection, which can easily damage the shaft or keyway surface. Flange connections typically require multiple bolts to be tightened simultaneously; disassembly must be done by gradually loosening them diagonally, otherwise uneven stress on the flange surface may cause deformation. Reinstallation requires step-by-step tightening according to standard torque, which is both time-consuming and labor-intensive. The grinding head is a consumable structure, and subsequent maintenance and replacement are inevitable. The inconvenience of assembly and disassembly greatly increases the difficulty of maintenance. Therefore, we propose a grinding disc structure for conductive agent grinding. Utility Model Content

[0005] To solve the above problems, this utility model provides a grinding disc structure for grinding conductive agents.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A grinding disc structure for grinding conductive agents, including a drive shaft;

[0008] A quick-release assembly is installed at the bottom of the drive shaft. The quick-release assembly includes a housing. The top of the housing has two symmetrical mounting slots. Guide rods are fixed to the inner walls of the mounting slots. Springs are sleeved on the outside of the guide rods. Slider blocks are also slidably installed in the mounting slots. A sliding hole is opened on one side wall of the slider to slide with the guide rod. Fixing rods are fixed to the two opposite ends of the two sliders. A cover plate is fixed to the top of the housing.

[0009] The bottom of the box is equipped with a grinding disc, and the top of the grinding disc is fixed with two symmetrical connecting brackets. Each connecting bracket has a slot, and both ends of the box are inserted into the slot. The outer wall of the connecting bracket is provided with fixing holes, through which the fixing rod passes. The bottom of the grinding disc is fixed with multiple grinding balls for grinding the conductive agent.

[0010] Furthermore, the connecting frame has a U-shaped cross-section and is tightly welded to the grinding disc.

[0011] Furthermore, the cross-sectional shape of the box is rectangular, and the dimensions of the box and the slot are matched.

[0012] Furthermore, the top of the cover plate has two slots, in which a lever is slidably installed. The bottom end of the lever is fixedly connected to the slider, and the top of the lever has a hole.

[0013] Furthermore, multiple reinforcing ribs are tightly welded at the connection between the drive shaft and the cover plate, and the multiple reinforcing ribs are distributed in a ring at equal intervals.

[0014] Furthermore, both the fixing rod and the fixing hole have rectangular cross-sectional shapes, and the dimensions of the fixing rod are adapted to the dimensions of the fixing hole.

[0015] Furthermore, the fixing rod and the slider are formed by an integral casting process, and the surface of the slider is subjected to a combination of grinding and electrolytic polishing.

[0016] Furthermore, the bottom of the grinding disc is curved, and multiple grinding balls are distributed in a ring at equal intervals.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] A quick-release assembly is installed between the drive shaft and the grinding disc: when maintenance of the grinding disc is required, simply pushing the lever causes the sliders on both sides to move synchronously and relative to each other. During this movement, the sliders cause the fixing rod to disengage from the fixing hole. Once the fixing rod is fully disengaged, the constraint between the housing and the connecting frame is released. At this point, the worker can quickly disassemble the grinding disc, making the entire process simple and fast, greatly saving time and labor costs. The installation process is equally efficient. Simply inserting the fixing rod quickly into the fixing hole allows for rapid installation between the drive shaft and the grinding disc, quickly establishing a stable and reliable connection. The application of this quick-release assembly not only effectively solves the problem of inconvenient disassembly and assembly of the grinding disc using traditional connection methods, but also greatly improves the efficiency of grinding disc maintenance, providing strong support for the continuity and stability of conductive agent production.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-5 As shown, the grinding disc structure for conductive agent grinding includes a drive shaft 1; a quick-release assembly 2 is installed at the bottom end of the drive shaft 1, the quick-release assembly 2 includes a housing 20, the top of the housing 20 has two symmetrical mounting grooves 200, the inner wall of each mounting groove 200 is fixed with a guide rod 22, and a spring 23 is sleeved on the outside of the guide rod 22; a slider 21 is also slidably installed in the mounting groove 200, and a sliding hole 210 is opened on one side wall of the slider 21 to slide with the guide rod 22. A fixing rod 25 is fixed to each of the opposite ends; a cover plate 26 is fixed to the top of the box body 20; a grinding disc 3 is provided below the box body 20, and two symmetrical connecting brackets 30 are fixed to the top of the grinding disc 3. Each connecting bracket 30 has a slot 300. Both ends of the box body 20 are inserted into the slot 300. A fixing hole 301 is provided on the outer wall of the connecting bracket 30, and the fixing rod 25 passes through the fixing hole 301; a number of grinding balls 31 for grinding conductive agents are fixed to the bottom of the grinding disc 3.

[0032] In this embodiment, the connecting frame 30 has a U-shaped cross-section and is tightly welded to the grinding disc 3. The U-shaped connecting frame 30 has better structural strength. This design ensures that the connecting frame 30 and the grinding disc 3 can be tightly connected, avoiding loosening or shaking, which would affect the installation effect of the grinding disc 3.

[0033] In this embodiment, the box body 20 has a rectangular cross-sectional shape, and the dimensions of the box body 20 and the slot 300 are compatible. The rectangular design facilitates the processing and installation of the box body 20, and the compatible dimensions allow the box body 20 and the slot 300 to fit precisely, which is conducive to achieving stable assembly of the overall structure.

[0034] In this embodiment, the top of the cover plate 26 has two slots 260, and a lever 24 is slidably installed in the slots 260. The bottom end of the lever 24 is fixedly connected to the slider 21, and the top of the lever 24 has a hole 240. This design facilitates operation, and the movement of the slider 21 can be flexibly controlled by the lever 24 to achieve quick assembly and disassembly.

[0035] In this embodiment, multiple reinforcing ribs 10 are tightly welded to the connection between the drive shaft 1 and the cover plate 26, and the multiple reinforcing ribs 10 are distributed in a ring with equal spacing. The reinforcing ribs 10 can enhance the structural strength of the connection, making the connection between the drive shaft 1 and the cover plate 26 more secure and able to withstand greater forces and torques.

[0036] In this embodiment, both the fixing rod 25 and the fixing hole 301 have rectangular cross-sectional shapes, and the dimensions of the fixing rod 25 are matched with the dimensions of the fixing hole 301. The rectangular cross-section effectively prevents the fixing rod 25 from wobbling within the fixing hole 301, ensuring the stability and accuracy of the transmission. The matching dimensions ensure a tight fit, enhance the reliability of the connection, and improve the overall structural performance.

[0037] In this embodiment, the fixing rod 25 and the slider 21 are formed by integral casting, and the surface of the slider 21 is treated with a combination of grinding and electrolytic polishing. Integral casting ensures the structural integrity of the fixing rod 25 and the slider 21, while surface treatment makes the surface of the slider 21 smooth, reduces friction, and improves the service life of the slider 21.

[0038] In this embodiment, the bottom of the grinding disc 3 is curved, and multiple grinding balls 31 are distributed in a ring with equal spacing. The curved surface design and the distribution of the grinding balls 31 enable more uniform grinding, improve grinding effect and efficiency, and meet better grinding requirements.

[0039] It should be added that the length of the groove 260 in this embodiment is less than the length of the slider 21. This design prevents the material from directly entering the mounting groove 200 through the groove 260 during the grinding of the conductive agent, thereby avoiding problems such as the accumulation of material in the mounting groove 200 causing the slider 21 to slide poorly.

[0040] When disassembling and maintaining the grinding disc 3, the user first pushes the lever 24, which slides along the groove 260. At the same time, the lever 24 drives the slider 21 to move horizontally, and the sliding hole 210 slides along the guide rod 22. The spring 23 is compressed by the slider 21, and at the same time, the slider 21 drives the fixing rod 25 to disengage from the fixing hole 301. Repeat the above steps, and make the fixing rod 25 on the other side disengage from the fixing hole 301. At this time, the restriction between the box 20 and the connecting frame 30 is released, and the connecting frame 30 disengages from the box 20, and the grinding disc 3 is disassembled.

[0041] Example 2

[0042] Please see Figure 6 As shown, this embodiment provides the following technical solution based on embodiment 1: mounting bolts 27 are provided at the four bottom corners of the cover plate 26, and threaded holes are provided at the four top corners of the box body 20. The mounting bolts 27 are threadedly connected to the corresponding threaded holes.

[0043] Understandably, this four-corner bolt connection structure ensures a stable and evenly distributed connection between the cover plate 26 and the box body 20, effectively preventing displacement or loosening of the cover plate 26 and the box body 20 during use, and ensuring the overall structural stability.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
