Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a sodium ion battery processing technology rolling equipment. Background Art

[0002] With the rapid development of fields such as renewable energy storage and electric vehicles, the demand for high-performance, low-cost batteries is growing. Sodium-ion batteries (Na-ion batteries) have attracted widespread attention due to their abundant sodium resources, relatively low cost, and similar operating principles to lithium-ion batteries. However, the performance of Na-ion batteries depends largely on the quality and structure of the electrode materials. During the manufacturing process of Na-ion batteries, the electrode materials need to undergo a series of processing steps to ensure their good electrochemical properties and mechanical stability.

[0003] Roll-pressing is a key process in the preparation of electrode materials. Traditional battery electrode processing technology often uses roller-pressing equipment with limitations when handling certain materials. For example, in early battery manufacturing, roller-pressing equipment may not be able to precisely control the compaction density of electrode materials, resulting in unstable electrode performance. For sodium-ion battery electrode materials, because their material properties differ from those of other battery materials, a more precise roller-pressing process is required to ensure the microstructure and performance of the materials.

[0004] Some existing roller-pressing equipment lacks precision in adjusting the roller gap. To improve the performance and production efficiency of sodium-ion batteries, a new type of roller-pressing equipment is urgently needed to overcome these limitations. This equipment must achieve breakthroughs in high precision, high efficiency, and high stability to meet the unique requirements of sodium-ion battery electrode material processing, thereby promoting the development of the sodium-ion battery industry.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1-3 As shown, a sodium ion battery processing technology rolling equipment proposed by an embodiment of the present invention includes a frame 1 and a base 2 fixedly mounted on the frame 1, a driving motor 3 is fixedly mounted on the bottom of the frame 1, one end of the driving motor 3 is connected to a reducer 4, one end of the reducer 4 is fixedly connected to a driving gear plate 5, a pressure gear plate 7 and a flat roller gear plate 8 are meshed and driven on the driving gear plate 5 through a chain 6, one end of the pressure gear plate 7 is fixedly connected to a lower pressure roller 9, an upper pressure roller 10 is provided in the middle of the lower pressure roller 9, and the upper pressure roller 10 is rotatably connected to a bearing seat 11, an upper end of the bearing seat 11 is connected to an adjusting rod 12, an upper part of the adjusting rod 12 is fixedly connected to an H-shaped plate 13, a precision electric push rod 14 is installed on the H-shaped plate 13, and the precision electric push rod 14 is installed on a fixed plate 15;

[0026] Frame 1 is the main support structure of the entire machine and provides a framework for the installation of other components. It is fixed to base 2, which stabilizes the machine and ensures that it does not shake or tilt during operation, providing a stable working platform for the entire rolling process.

[0027] The drive motor 3 is the power source of the equipment, which provides rotational power. Since the motor usually has a fast speed and a small output torque, the speed reducer 4 is used to reduce the motor speed and increase the torque to meet the needs of the rolling work.

[0028] The driving gear disc 5 at one end of the reducer 4 cooperates with the chain 6, which plays a transmission role and transmits power to the pressure gear disc 7 and the flat roller gear disc 8. Among them, the number of pressure gear discs 7 can be several and they are on the same straight plane, so that multiple rolling can be achieved to improve the processing quality of the electrode material.

[0029] The flat roller plane of the flat roller toothed disc 8 and the lowest plane of the lower pressing roller 9 are on the same plane straight line, which ensures the smooth transportation of the material during the rolling process.

[0030] The concave lower roller 9 and the convex upper roller 10 facilitate more uniform compaction of the sodium-ion battery electrode material. As the electrode material passes between the two rollers, it is squeezed by the convex upper roller 10 and the concave lower roller 9, changing its thickness and density.

[0031] The upper pressing roller 10 is rotatably connected to the bearing seat 11. The bearing seat 11 provides support for the rotation of the upper pressing roller 10 and reduces friction resistance during the rotation process.

[0032] The upper end of the bearing seat 11 is connected to the adjusting rod 12, which can transmit the position adjustment information of the upper pressure roller 10. The upper part of the adjusting rod 12 is fixedly connected to the H-shaped plate 13, which serves as an intermediate connecting piece and provides a position for the installation of the precision electric push rod 14.

[0033] The precision electric push rod 14 is mounted on the fixed plate 15, which is mounted on the side of the frame 1. The precision electric push rod 14 can accurately push the H-shaped plate 13 up and down, and then drive the bearing seat 11 and the upper pressing roller 10 to move up and down through the adjustment rod 12, so as to achieve precise adjustment of the distance between the upper pressing roller 10 and the lower pressing roller 9 to meet the rolling requirements of electrode materials of different thicknesses;

[0034] Working principle:

[0035] Power transmission stage

[0036] After the drive motor 3 is started, it generates rotational power. Due to its high speed and low torque, the speed is reduced and the torque is increased by the connected reducer 4. The drive gear 5 at one end of the reducer 4 engages with the chain 6, which transmits power to the pressure gear 7 and the flat roller gear 8.

[0037] Rolling preparation stage

[0038] The pressure gear disc 7 drives the lower pressing roller 9 to rotate, while the flat roller gear disc 8 drives the flat roller to rotate. At this point, the electrode material is ready to enter the rolling area. The plane where the flat roller gear disc 8 connects to the flat roller and the lowest plane of the lower pressing roller 9 are aligned on the same plane, ensuring a smooth transition of the electrode material from the flat roller to the lower pressing roller 9.

[0039] Rolling process stages

[0040] The electrode material enters between the concave lower roller 9 and the convex upper roller 10. Driven by a power source, the lower and upper rollers 9 and 10 rotate relative to each other. The upper roller 10 is rotatably connected to a bearing block 11, which provides support for its rotation and reduces frictional resistance. As the electrode material passes between these two matching rollers, it is squeezed, causing its thickness and density to change.

[0041] Roller gap adjustment stage

[0042] Depending on the thickness requirements of the electrode material, a precision electric push rod 14 comes into operation. This push rod 14 is mounted on a fixed plate 15, which is fixed to the side of the frame 1. This push rod 14 pushes the H-shaped plate 13 up and down, which in turn drives the adjustment rod 12, which is fixed to it. The adjustment rod 12 transmits this movement information to the bearing seat 11, thereby driving the upper pressure roller 10 up and down, achieving precise adjustment of the gap between the upper pressure roller 10 and the lower pressure roller 9.

[0043] Auxiliary support stage

[0044] The protective cover on the outside of the chain 6 is fixedly connected to the frame 1, protecting the chain 6 from external interference during operation and ensuring the safety of the operator. The tungsten carbide wear-resistant coating on the surface of the lower and upper pressure rollers 9 and 10 reduces wear on the roller surface during long-term rolling, extending the service life of the equipment.

[0045] When there are several pressing teeth 7 and they are located on the same straight plane, multiple rolling operations can be achieved, thereby further improving the processing quality of the electrode material.

[0046] like Figure 2 As shown, in some embodiments, multiple toothed discs 7 are provided and located on the same linear plane. Multiple toothed discs 7 located on the same linear plane allow the electrode material to be rolled within a relatively stable linear channel. This prevents problems such as material deviation or distortion during transport. If the toothed discs 7 are not located on the same linear plane, the electrode material may experience positional deviations when transitioning from one roller area to another, thereby affecting the final processing quality.

[0047] like Figure 3 As shown, in some embodiments, the lower pressing roller 9 is concave and the upper pressing roller 10 is convex, with the shapes being adapted. During the rolling process, the electrode material enters between the concave area of ​​the lower pressing roller 9 and the convex area of ​​the upper pressing roller 10. Due to the adapted shapes, the electrode material can be subjected to relatively uniform pressure across the entire width.

[0048] like Figure 1As shown, in some embodiments, the fixing plate 15 is installed on the side of the frame 1; the fixing plate 15 is installed on the side of the frame 1, which makes the installation position of the precision electric push rod 14 relatively fixed and stable.

[0049] like Figure 1 As shown, in some embodiments, the flat roller toothed disc 8 is connected to the flat roller, and the plane of the flat roller and the lowest plane of the lower pressing roller 9 are on the same plane straight line; this planar design of the flat roller connected by the flat roller toothed disc 8 and the lower pressing roller 9 enables the electrode material to be seamlessly connected during the process of being transferred from the flat roller to the lower pressing roller 9.

[0050] like Figure 1 As shown, in some embodiments, a protective cover is provided on the outside of the chain 6, and the protective cover is fixedly connected to the frame 1; the presence of the protective cover effectively isolates the chain 6 from the operator, avoiding the safety risks caused by the operator accidentally touching the chain 6, and providing important protection for the safety of the operator.

[0051] In some embodiments, the surfaces of the lower pressing roller 9 and the upper pressing roller 10 are coated with a wear-resistant coating, which may be a tungsten carbide coating. During the rolling process, if the roller surfaces are severely worn, impurities such as metal debris may be mixed into the electrode material, thereby contaminating the electrode material. The presence of the tungsten carbide coating can effectively prevent excessive wear debris from the roller surfaces, ensuring the purity of the electrode material and ensuring that the performance of the sodium-ion battery is not affected by impurities.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
