Description

Technical Field

[0001] This utility model belongs to the field of graphite sheet cutting technology, and in particular relates to a graphite sheet cutting blade and a graphite sheet cutting machine. Background Technology

[0002] The manufacturing processes of graphite flakes are mainly divided into two categories: physical processing and chemical synthesis. Physical processing, based on natural or artificial graphite blocks, has become the mainstream choice for current industrial applications due to its significant cost advantages and ease of large-scale production. This process typically includes two core steps: cutting and grinding. First, the graphite block is separated into flakes using cutting blades, and then the cut surfaces are surface-treated.

[0003] However, existing cutting blade designs have significant flaws. Their non-cutting areas are generally flat, limiting the blades to a single cutting function. During cutting, graphite materials are prone to micro-cracks and surface unevenness, resulting in graphite flakes with high roughness that cannot directly meet product specifications. To address this issue, the industry commonly employs a staged grinding process: first, coarse polishing with sandpaper of different grits to eliminate obvious defects; then, fine polishing with high-precision equipment to ensure surface smoothness. This multi-step processing mode not only extends the overall manufacturing cycle of individual products but also increases equipment investment and manual operation, leading to low production efficiency, increased resource consumption, and severely restricting the scale and economy of graphite flake production. Summary of the Invention

[0004] The purpose of this utility model is to provide a graphite sheet cutting blade and a graphite sheet cutting machine, which has the advantages of simplifying the processing flow, avoiding the need for additional grinding after cutting, and improving production efficiency.

[0005] To address the aforementioned problems, this utility model provides a graphite sheet cutting blade, the technical solution of which is as follows: It includes a blade body and a grinding layer. The blade body has a cutting edge, and the grinding layer is located on the surface of the blade body.

[0006] Furthermore, this application also proposes that the grinding layer includes abrasive particles, and the diameter of the abrasive particles gradually decreases along the direction away from the cutting edge.

[0007] Furthermore, this application also proposes that the grinding layer includes multiple grinding areas, each grinding area is covered with grinding particles, the multiple grinding areas are arranged sequentially, and the diameter of the grinding particles in each grinding area gradually decreases along the direction away from the cutting edge.

[0008] Furthermore, this application also proposes that the blade body is circular, with the cutting edge located on the outer edge of the blade body.

[0009] Furthermore, this application also proposes that the grinding area is annular, and multiple grinding areas are concentrically arranged.

[0010] Furthermore, this application also proposes that the blade body is rectangular, with the cutting edge located on one side of the blade body.

[0011] Furthermore, this application also proposes that the grinding area be rectangular.

[0012] On the other hand, this utility model embodiment provides a graphite sheet cutting machine, including a drive mechanism and the aforementioned graphite sheet cutting blade. The drive mechanism is used to drive the graphite sheet cutting blade to move so that the graphite sheet cutting blade cuts graphite blocks.

[0013] Furthermore, this application also proposes that the drive mechanism includes a drive component and a reduction component, the reduction component being connected to the drive component in a transmission manner, and the reduction component being able to drive the graphite sheet cutting blade to move.

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In traditional graphite sheet manufacturing processes, physical processing methods based on natural or synthetic graphite blocks are widely used due to their cost advantages. A typical process involves two separate steps: cutting and grinding. Because the non-cutting surfaces of the cutting blades are usually designed with a flat structure, the blades only have a single cutting function. After cutting, microscopic unevenness inevitably occurs on the graphite sheet surface. This surface roughness cannot meet the final product requirements, thus necessitating an additional grinding step. Specifically, the initial cut surface needs to undergo a rough polishing process with sandpaper of different grits, followed by a fine polishing process, to gradually improve surface quality. This separate process design prevents cutting and grinding from being performed simultaneously, directly resulting in a lengthy process flow, significantly extending the production cycle, and negatively impacting the overall production efficiency of the factory. The reduced efficiency is mainly reflected in a decrease in the number of products that can be completed per unit time and a decline in the utilization rate of equipment and human resources.

[0023] For example, in the actual operation of a graphite sheet production line, when using conventional cutting blades to cut graphite blocks, the blades only perform cutting motions, resulting in a rough surface with randomly distributed microcracks and raised bumps. Operators must immediately transfer the cut semi-finished product to the rough polishing station, where it is manually or semi-automatically polished with 80-grit sandpaper to remove the noticeable bumps. Subsequently, the semi-finished product is transported to the fine polishing station, where a polishing machine using fine abrasives is used to improve the surface finish. During this process, frequent material transfers, equipment changes, and manual interventions between processes disrupt the continuity of the production line. Furthermore, because cutting and grinding are done at different stations, operators need to repeatedly adjust the workpiece position and change processing tools, significantly increasing the dwell time of each product in the grinding stage, thus hindering the smooth operation of the production line and increasing the proportion of non-value-added operations.

[0024] If the surface treatment problems caused by the separation of the aforementioned processes are not resolved, the graphite sheet manufacturing process will continue to rely on a multi-step, sequential processing mode. This extended production cycle will not only exacerbate equipment downtime and manpower waiting times but may also lead to inconsistencies in surface treatment quality, such as localized over- or under-grinding defects caused by improper transitions between rough and fine polishing processes. The accumulation of such defects will directly affect the stability of subsequent processes, increasing the risk of product non-conformity when entering the final inspection stage. Furthermore, the increased complexity of the process will raise the difficulty of production management, including coordination costs in process scheduling, quality monitoring, and material flow, thus posing a continuous constraint on the overall reliability and resource utilization efficiency of the manufacturing system.

[0025] For this, please refer to Figure 1 and Figure 2 This application proposes a graphite sheet cutting blade 100, including a blade body 110 and a grinding layer 120. The blade body 110 is provided with a cutting edge 111, and the grinding layer 120 is provided on the surface of the blade body 110.

[0026] This embodiment relates to a graphite sheet cutting blade 100, including a blade body 110 and a grinding layer 120. The blade body 110 has a cutting edge 111, and the grinding layer 120 is disposed on the surface of the blade body 110. The grinding layer 120 is a structure used to improve the surface roughness of the graphite sheet in real time during the cutting process, and its function is to reduce the unevenness of the surface after cutting through physical action. In practical applications, the grinding layer 120 can be implemented by coating with abrasive particles, for example, fixing diamond particles to the surface of the blade body 110 through an electroplating process; furthermore, the grinding layer 120 can be composed of abrasive materials formed by a sintering process, for example, depositing silicon carbide particles on the surface using thermal spraying technology. As a preferred embodiment, the grinding layer 120 can contain a mixture of abrasive particles of different sizes to provide multi-stage grinding action, wherein the particle size distribution of the abrasive particles can be adjusted according to actual needs. Therefore, this embodiment integrates a grinding layer 120 on the surface of the blade body 110, enabling the cutting and grinding processes to proceed simultaneously. This avoids the need for separate rough and fine polishing steps after cutting, as is required in traditional methods, shortening the processing cycle and improving production efficiency. Specifically, the blade body 110 serves as a basic support structure, ensuring the stability of the cutting and grinding operations; the cutting edge 111 performs the initial cutting of the graphite block, forming a kerf; and the grinding layer 120 acts on the surface in real time according to the cutting dynamics, directly processing rough areas, thereby simplifying the process flow.

[0027] During the graphite sheet cutting process, the blade body 110 is constructed as the basic structure to provide a stable support platform, ensuring the reliability of the cutting and grinding processes. The cutting edge 111 is disposed on the blade body 110 to perform the cutting operation on the graphite block, forming the initial kerf. The grinding layer 120 is disposed on the surface of the blade body 110, capable of real-time grinding treatment based on the surface roughness generated during the cutting process, thereby improving the surface roughness instantly during cutting and achieving simultaneous cutting and grinding.

[0028] Specifically, in a preferred embodiment, the grinding layer 120 may be composed of a coating of silicon carbide particles uniformly adhered to the surface of the blade body 110, with the particle size being appropriate to meet basic grinding requirements. Thus, the surface roughness resulting from the cutting operation is addressed immediately, eliminating the need for subsequent separate rough and fine polishing processes, effectively shortening the processing cycle and improving production efficiency.

[0029] In practical applications, in some embodiments of this application, a grinding layer 120 is proposed to simultaneously achieve surface grinding during the cutting process. However, in its implementation, if the grinding particles are uniformly distributed, they cannot match the required gradient of surface treatment after cutting, resulting in the graphite sheets after cutting still needing to undergo rough polishing and fine polishing processes in stages, which prolongs the processing cycle and reduces production efficiency.

[0030] In this regard, this application further proposes that the grinding layer 120 includes grinding particles, and the diameter of the grinding particles gradually decreases along the direction away from the cutting edge 111.

[0031] Among them, abrasive particles refer to tiny hard particles, which can be made of materials such as diamond, silicon carbide or alumina. Their purpose is to provide surface grinding capability during the cutting process. The gradually decreasing diameter can be understood as the size of the abrasive particles decreasing in the direction away from the cutting edge 111. This can be achieved in a continuous and gradual manner, with the aim of matching the gradient requirements of surface treatment after cutting and achieving a natural transition from coarse grinding to fine grinding.

[0032] Specifically, the solution of this application uses a gradient distribution of grinding particle diameter to enable larger particles near the cutting edge 111 to quickly remove significant unevenness in the early stage of cutting when cutting graphite blocks, achieving efficient coarse grinding. As the cutting progresses to the area away from the cutting edge 111, the gradually shrinking particle diameter naturally transitions to fine grinding, ensuring that the surface smoothness is gradually improved, thereby completing the continuous processing from coarse polishing to fine polishing in a single cutting operation.

[0033] As a preferred embodiment, the solution of this application is specifically implemented as follows: the abrasive particles in the abrasive layer 120 can be made of diamond material, wherein the particle diameter is larger near the cutting edge 111 and covers a wider range, while the particle diameter gradually decreases away from the cutting edge 111, forming a smooth transition.

[0034] By using the above solution, this application effectively avoids the cumbersome process of traditional multi-step polishing, significantly simplifies the process flow, shortens the processing cycle, and improves production efficiency.

[0035] Specifically, in some embodiments of this application, the grinding layer 120 includes multiple grinding areas 121 to integrate the cutting and polishing processes. However, in its implementation, the single-structure grinding layer 120 cannot adapt to the gradual change in surface roughness from the initial cutting to subsequent processing, resulting in the need for additional rough and fine polishing processes after cutting, which prolongs the processing cycle and reduces production efficiency.

[0036] Please see Figure 1 and Figure 2 In this regard, this application further proposes that the grinding layer 120 includes multiple grinding regions 121, each grinding region 121 is covered with grinding particles, the multiple grinding regions 121 are arranged sequentially, and along the direction away from the blade 111, the diameter of the grinding particles in each grinding region 121 gradually decreases.

[0037] In practical applications, multiple grinding areas 121 refer to the grinding layer 120 being divided into several independent functional areas, which can be implemented using a fan-shaped, strip-shaped, or irregular polygonal layout. The purpose is to adapt to the gradual change in surface roughness required during the cutting process. The grinding areas 121 are covered with grinding particles, which can be understood as each area having a fixed grinding material, specifically diamond particles, silicon carbide particles, or alumina particles. The purpose is to provide grinding capabilities for different roughness stages. Specifically, the multiple grinding areas 121 are arranged sequentially, meaning the areas are arranged in a specific direction. They can be configured to be distributed sequentially along the linear or radial direction of the blade surface. The purpose is to ensure that the material passes through each processing stage sequentially during the cutting motion. Along the direction away from the cutting edge 111, the diameter of the grinding particles in each grinding area 121 gradually decreases. This feature can be described as a transition in particle size from coarse to fine. For example, a particle sequence with decreasing diameter can be used. The purpose is to match the processing requirements from the initial high roughness of the cut to the subsequent smooth surface.

[0038] Specifically, the solution of this application structures the grinding layer 120 into multiple functional areas, allowing the material to sequentially pass through each area along the blade's movement trajectory, forming a continuous processing flow from roughing to finishing. Along the direction away from the cutting edge 111, the diameter of the grinding particles gradually decreases. This utilizes the physical characteristic that the contact point of the cutting edge 111 produces the highest roughness during cutting, requiring larger particles for rapid finishing. Simultaneously, it combines the natural increase in surface smoothness as the material moves away from the cutting edge 111, enabling smaller diameter particles to undergo immediate fine polishing. Thus, the entire process from initial cutting to final polishing is completed simultaneously in a single cutting action.

[0039] As a preferred embodiment, the solution of this application is specifically implemented as follows: the blade body 110 of the graphite sheet cutting blade 100 is designed as a polygonal structure, with the cutting edge 111 located on the outer edge; the grinding layer 120 includes four grinding areas 121, which are arranged in a radial strip pattern along the direction away from the cutting edge 111. Each area is covered with grinding particles of different diameters, with the particle diameter gradually transitioning from the large particle area near the cutting edge 111 to the small particle area away from the cutting edge 111. The grinding particles are made of diamond material to ensure that each area has basic grinding capabilities.

[0040] Through the above solution, the surface treatment is completed simultaneously during the graphite sheet cutting process, avoiding the need for additional rough and fine polishing after cutting in traditional processes, which significantly shortens the processing cycle and improves factory production efficiency.

[0041] In practical applications, some embodiments of this application propose that the grinding layer 120 includes multiple grinding areas 121 to achieve rough polishing and fine polishing during the cutting process. However, in this process, since the shape of the blade body 110 is not optimized, when using a non-circular blade, the arrangement of the grinding areas 121 is difficult to uniformly cover the cutting surface, resulting in inconsistent surface roughness after cutting. Additional manual grinding or fine polishing is still required, which prolongs the processing cycle and reduces production efficiency.

[0042] Please see Figure 1 In this regard, this application further proposes that the blade body 110 is circular and the cutting edge 111 is located on the outer edge of the blade body 110.

[0043] The circular shape of the blade body 110 refers to its circular shape, which can be achieved by using an integral stamped metal disc structure. The purpose is to provide rotational symmetry, which facilitates the formation of a continuous gradient distribution of the grinding area 121 along the radial direction. The cutting edge 111 located at the outer edge of the blade body 110 means that the cutting edge 111 is set at the outermost edge of the blade body 110. It can be achieved by using laser cutting technology to form a continuous cutting edge or a discontinuous tooth structure on the outer edge. The purpose is to ensure that the cutting edge 111, as the starting point of cutting, directly contacts the graphite material for initial cutting.

[0044] Specifically, the circular design of the blade body 110 allows the grinding area 121 to be distributed in a natural and continuous manner along the radial direction. When the blade is driven by the drive mechanism to rotate and cut the graphite block, the cutting surface passes through grinding particles of different sizes sequentially from the blade 111, forming a smooth transition process from coarse grinding to fine grinding. At the same time, the characteristic of the blade 111 being located at the outer edge ensures that the newly formed surface is immediately processed by the grinding layer 120 after the cutting action occurs. The inertia of the blade rotation makes the grinding particles apply force evenly, thereby completing the surface finishing simultaneously in a single cutting operation, avoiding the problem of area discontinuity or coverage dead corners caused by non-circular blades.

[0045] As a preferred embodiment, the solution of this application is specifically implemented as follows: The blade body 110 of the graphite sheet cutting blade 100 adopts a circular stainless steel disc, and the cutting edge 111 is formed by precision grinding at the outer edge to form a sharp cutting edge. The grinding layer 120 includes multiple grinding areas 121. These areas are laid with diamond abrasive particles in a concentric ring. Along the direction away from the cutting edge 111, the diameter of the abrasive particles in each area gradually decreases. The inner layer area is laid with coarse-diameter particles, the middle layer area is laid with medium-diameter particles, and the outer layer area is laid with fine-diameter particles.

[0046] Through the above solution, this application effectively solves the problem of uneven distribution of the grinding area 121, avoids the phenomenon of inconsistent surface roughness after cutting, reduces the need for additional manual grinding or fine polishing, thereby shortening the processing cycle and improving production efficiency.

[0047] In practical applications, in some embodiments of this application, multiple grinding areas 121 are proposed to gradually grind the surface of the graphite sheet during the cutting process. However, in this process, when the blade body 110 is circular, the shape of the grinding area 121 is not adapted to the circular structure, resulting in uneven grinding effect and failing to effectively replace the subsequent rough polishing and fine polishing steps.

[0048] Please see Figure 1 In this regard, this application further proposes that the grinding area 121 is annular and that multiple grinding areas 121 are concentrically arranged.

[0049] The grinding area 121 is annular, meaning that the shape of the grinding area 121 is designed as an annular structure. It can be a complete annular ring or a segmented annular area. The purpose is to adapt to the rotational movement trajectory of the circular blade body 110, ensure that the graphite sheet surface is in uniform contact with the grinding particles during the cutting process, and avoid local over-grinding or under-grinding caused by irregular area shape. The concentric arrangement of multiple grinding areas 121 can be understood as multiple annular areas arranged with the center of the blade body 110 as the common center. It can be implemented by using a concentric circle layout with equal spacing or variable spacing. The purpose is to make the diameter of the grinding particles continuously and gradually change along the radius of the blade, so as to naturally achieve the transition from coarse grinding to fine grinding during the cutting process.

[0050] Specifically, the solution of this application designs the grinding area 121 as an annular shape and sets it concentrically with the blade body 110. When the blade rotates to cut the graphite block, the surface of the graphite sheet passes through areas of grinding particles of different diameters uniformly and sequentially along the rotation path. Since the diameter of the grinding particles gradually decreases in the direction away from the blade 111, the cut surface undergoes a grinding process from coarse to fine starting from the outer edge, effectively replacing the traditional coarse and fine polishing steps and realizing an integrated operation of cutting and grinding.

[0051] As a specific implementation method, the solution of this application is implemented as follows: The blade body 110 adopts a circular design, and the grinding area 121 includes three concentric annular areas. The outermost annular area is covered with abrasive particles of larger diameter for preliminary roughing treatment, the middle annular area is covered with abrasive particles of medium diameter for intermediate grinding, and the innermost annular area is covered with abrasive particles of smaller diameter to achieve fine polishing.

[0052] Through the above solution, this application achieves uniform surface grinding during the graphite sheet cutting process, avoids the problem of uneven grinding effect, effectively reduces the need for subsequent polishing processes, shortens the processing cycle, and improves factory production efficiency.

[0053] Specifically, in some embodiments of this application, the grinding layer 120 includes multiple grinding areas 121 to achieve graded grinding simultaneously during the cutting process. However, in its implementation, when applied to a straight cutting scenario, the structure of the circular blade cannot adapt to the straight motion trajectory, causing the particle diameter gradient design of the grinding area 121 to be unable to effectively act on the cutting surface. Additional rough polishing and fine polishing processes are still required, which prolongs the processing cycle and reduces production efficiency.

[0054] Please see Figure 2 In this regard, this application further proposes that the blade body 110 is rectangular and the cutting edge 111 is located on one side of the blade body 110.

[0055] The blade body 110 is rectangular, meaning that the overall outline of the blade is rectangular. It can be a rectangle, a square, or other rectangular variants. The purpose is to adapt to the linear motion trajectory and avoid the grinding failure caused by the mismatch of the trajectory when the circular blade is cutting in a straight line. The cutting edge 111 is located on one side of the blade body 110, which can be understood as the cutting edge 111 being set on one edge of the rectangle. Specifically, it can be the entire edge or part of the edge. The purpose is to ensure that during the linear advance, the cutting edge 111 first contacts the graphite block to complete the cutting action, and then the grinding area 121 acts on the newly formed cutting surface in the direction away from the cutting edge 111.

[0056] Specifically, the solution of this application designs the blade body 110 as rectangular and positions the cutting edge 111 on one side, enabling the cutting blade to adapt to linear motion scenarios. The rectangular blade body 110 allows the blade to be installed in a linearly driven cutting device. When the blade advances in a linear direction, the cutting surface can sequentially pass through different areas of the grinding layer 120. The positioning of the cutting edge 111 on one side ensures that the cutting edge 111 first contacts the graphite block for cutting, and then the grinding area 121 naturally transitions from coarse grinding to fine grinding according to the gradual change characteristics of the particle diameter, thereby integrating cutting and grinding functions in a single cutting stroke.

[0057] As a specific implementation method, the solution of this application is implemented as follows: the blade body 110 adopts a rectangular metal substrate, and the cutting edge 111 is disposed on one long side of the rectangle; the grinding layer 120 includes a plurality of strip-shaped grinding areas 121, which are arranged sequentially in a direction away from the cutting edge 111.

[0058] Through the above solution, this application can simultaneously achieve cutting and graded grinding during the graphite sheet cutting process, eliminating the need for multiple grinding processes after cutting in traditional processes, thereby shortening the processing cycle and improving production efficiency.

[0059] The manufacturing processes for graphite sheets fall into two main categories: one is the physical processing based on natural or artificial graphite blocks, and the other is the chemical synthesis of thin graphite sheets. From a cost perspective, physical processing is cheaper and easier to industrialize. Therefore, most existing graphite sheets are currently produced through physical processing, typically involving two steps: cutting and grinding. However, currently, the non-cutting surfaces of cutting blades are mostly flat, limiting the blade's function to cutting. Due to surface roughness caused by cutting or the final product requirements, some products typically require rough polishing with sandpaper of different grits after cutting, followed by fine polishing with a more precise polishing machine. The processing cycle from cutting to rough polishing to fine polishing is relatively long, resulting in low factory production efficiency.

[0060] In some of the embodiments described above in this application, a grinding area 121 is proposed to achieve a self-grinding function during the cutting process. However, in its implementation, when the blade body 110 is rectangular and the cutting edge 111 is located on one side, the shape of the grinding area 121 is not defined, which may lead to a mismatch with the geometry of the blade, resulting in uneven distribution of grinding particles, low grinding efficiency in the edge area, or rough local surface, which cannot effectively replace the subsequent polishing process, thereby extending the processing cycle and reducing production efficiency.

[0061] Please see Figure 2 In this regard, this application further proposes that the grinding area 121 is rectangular.

[0062] Specifically, the grinding area 121 refers to the area on the surface of the blade body 110 used to lay grinding particles. It can be implemented in a rectangular shape to ensure that it is completely consistent with the outline of the rectangular blade body 110, avoiding blind spots in surface coverage or discontinuities in particle distribution due to shape differences. Its purpose is to enable the grinding area 121 to uniformly receive the grinding particle sequence during the cutting process, thereby effectively handling the micro-unevenness of the graphite sheet surface.

[0063] Specifically, the solution of this application defines the grinding area 121 as a rectangle, so that it precisely matches the geometry of the rectangular blade body 110. During the cutting of graphite sheet, the grinding area 121 can uniformly distribute grinding particles in a direction away from the blade 111, so that the transition process from coarse grinding to fine grinding closely follows the movement trajectory of the blade, thereby efficiently handling the micro-unevenness of the surface while cutting and reducing the dependence on additional polishing steps.

[0064] In one specific implementation, the blade body 110 of the graphite sheet cutting blade 100 of this application can be rectangular, the cutting edge 111 is located on one side, the grinding area 121 can be rectangular and covers the surface of the blade body 110, and the diameter of the grinding particles gradually decreases along the direction away from the cutting edge 111.

[0065] Through the above solution, this application ensures the compatibility of the grinding area 121 with the shape of the blade body 110, effectively avoids the problems of uneven distribution of grinding particles and local surface roughness, reduces the dependence on additional polishing steps, shortens the processing cycle, and improves production efficiency.

[0066] In another embodiment, this application also discloses a graphite sheet cutting machine, including a drive mechanism and a graphite sheet cutting blade 100 with a grinding layer 120. The drive mechanism is used to drive the graphite sheet cutting blade 100 to move so that the graphite sheet cutting blade 100 cuts graphite blocks.

[0067] The core innovation of this embodiment lies in combining the graphite sheet cutting blade 100 with the grinding layer 120 and the drive mechanism, enabling simultaneous grinding during the cutting process. This directly reduces surface roughness when cutting graphite blocks, achieving the effect of omitting subsequent polishing processes and shortening the processing cycle. Specifically, when the graphite sheet cutting blade 100 performs the cutting operation, the grinding layer 120 on its surface acts on the graphite block surface in real time according to the cutting dynamics, instantly improving the microscopic unevenness generated by cutting through the physical action of the grinding particles. Based on this, the drive mechanism is configured to provide stable motion control, ensuring precise synchronization of cutting and grinding actions and avoiding additional surface defects caused by unstable motion. In practical applications, the grinding layer 120 can be composed of a coating of silicon carbide particles, which is uniformly adhered to the surface of the blade body 110. The particle size distribution is optimized to achieve continuous processing from coarse to fine grinding during the cutting process. As a result, the cutting and grinding processes are integrated into a single operation, effectively eliminating the redundant steps of transferring materials to rough and fine polishing stations after cutting, which is a traditional process. This significantly reduces the time lost due to material transfer, equipment switching, and manual intervention. Through this technical solution, not only is the risk of inconsistent surface treatment quality reduced, but the utilization rate of equipment and human resources is also improved, ultimately achieving a substantial increase in production efficiency.

[0068] In practical applications, some embodiments of this application propose a drive mechanism including a drive component and a deceleration component to precisely control the cutting speed and improve the quality of the cutting surface. However, in its implementation, if the drive mechanism lacks a deceleration function, direct high-speed drive will lead to a significant increase in the surface roughness of the graphite sheet cutting, which in turn will trigger frequent intervention of subsequent grinding processes, prolong the processing cycle and reduce the factory's production efficiency.

[0069] In this regard, this application further proposes that the drive mechanism includes a drive component and a reduction component, the reduction component is connected to the drive component in a transmission manner, and the reduction component can drive the graphite sheet cutting blade 100 to move.

[0070] The drive component refers to the core component that provides the original power output. It can be implemented using an electric motor, hydraulic motor, or pneumatic motor, with the aim of establishing a stable and reliable power foundation for the cutting process. The reduction component refers to the functional unit that performs speed regulation and torque amplification. It can be implemented using a gear reducer, planetary reduction mechanism, or belt reduction device, with the aim of dynamically adapting the cutting speed according to the brittle characteristics of graphite material. The transmission connection refers to the physical interface for power transmission between the drive component and the reduction component. It can be implemented using a coupling, gear meshing, or chain drive, with the aim of ensuring the continuity and stability of the power transmission process. The driving relationship between the output end of the reduction component and the blade refers to the driving relationship between the output end of the reduction component and the blade. It can be implemented by direct fixed connection or indirect transmission through an intermediate support structure, with the aim of ensuring that the blade maintains a low-speed and stable operating state during the cutting operation.

[0071] Specifically, the solution of this application outputs the original power through the drive component, and continuously transmits the power to the reduction component through the transmission connection. The reduction component precisely controls the rotation speed based on the physical properties of graphite material, so that the cutting speed is dynamically matched with the brittleness of the material, effectively suppressing the material fracture and surface unevenness caused by high-speed cutting. The output end of the reduction component directly drives the graphite sheet cutting blade 100 to rotate at a low speed. By reducing the cutting line speed, the generation of edge burrs and microcracks is reduced, thereby weakening the necessity of the subsequent grinding process.

[0072] As a specific implementation method, the solution of this application is implemented as follows: the drive component is specifically an AC servo motor, the reduction component is specifically a planetary gear reduction mechanism, and the two are reliably connected by a flexible coupling; the graphite sheet cutting blade 100 is directly installed at the end of the output shaft of the reduction component, so that the blade maintains a low-speed stable rotation state when cutting graphite blocks.

[0073] Through the above solution, the surface roughness of the graphite sheet cut in this application is effectively improved, the cutting defects caused by speed runaway are reduced, thereby reducing the frequency of subsequent grinding processes, shortening the processing time of a single product, and improving the overall production efficiency.

[0074] Specifically, in some embodiments of this application, a tool holder is proposed for mounting a graphite sheet cutting blade 100. However, in its implementation, since the deceleration assembly directly drives the blade to move, the blade lacks a stable intermediate support structure, which easily leads to vibration and displacement during cutting, resulting in increased surface roughness of the graphite sheet. At the same time, the blade replacement operation requires direct disassembly from the deceleration assembly, which is cumbersome and time-consuming, reducing production continuity and overall efficiency.

[0075] In this regard, this application further proposes that the graphite sheet cutting machine also includes a tool holder, which is mounted on the reduction gear assembly, and the graphite sheet cutting blade 100 is mounted on the tool holder.

[0076] The tool holder refers to the intermediate structural component used to fix and support the graphite sheet cutting blade 100. It can be implemented using a platform or clamp made of metal material, with the aim of providing a stable installation base and reducing vibration during the cutting process. The installation of the tool holder on the reduction assembly can be understood as the mechanical connection between the tool holder and the reduction assembly. It can be implemented by bolt connection, snap connection or flange connection, etc., with the aim of ensuring that the movement of the reduction assembly is smoothly transmitted to the tool holder. In practical applications, the installation of the graphite sheet cutting blade 100 on the tool holder specifically refers to the fixing method between the blade and the tool holder. It can be implemented by clamping mechanism, threaded connection or magnetic adsorption, etc., with the aim of realizing modular installation of the blade for easy and quick replacement.

[0077] Specifically, the solution of this application uses a tool holder as an intermediate support structure to smoothly transmit the movement of the reduction assembly to the graphite sheet cutting blade 100. When the reduction assembly drives the tool holder, the tool holder absorbs and reduces vibration transmission, avoiding shaking caused by direct blade connection. At the same time, the graphite sheet cutting blade 100 is modularly installed through the tool holder, so that when changing the blade, only the tool holder needs to be operated, without adjusting the reduction assembly itself, thus forming a complete support and transmission system, effectively ensuring the stability of the cutting process and the convenience of maintenance.

[0078] As a preferred embodiment, the solution of this application is implemented as follows: the tool holder can be a circular platform made of aluminum alloy material, which is fixed to the output shaft of the reduction assembly by bolts; the graphite sheet cutting blade 100 is installed on the tool holder by an adjustable clamping mechanism, which includes multiple jaws and fastening bolts, and can adapt to blades of different sizes, thereby realizing the rapid positioning and fixing of the blade.

[0079] Through the above solution, vibration and displacement during the graphite sheet cutting process of this application are effectively suppressed, and the surface roughness of the cut surface is reduced; at the same time, the blade replacement operation is simplified, production continuity is improved, and overall efficiency is optimized.
