Description

Technical Field

[0001] This invention relates to the field of cutting tool grinding technology, and in particular to an automatic grinding and repair device and method for cotton core external cutting tools. Background Technology

[0002] The cotton wick cutter is a core tool in the cotton wick processing field. Its blade sharpness and surface precision directly determine the cutting quality and processing efficiency. After long-term use, the blade is prone to wear and chipping, requiring timely grinding and repair to extend its service life. Chemical mechanical polishing (CMP), as an efficient surface treatment technology, has been widely used in the grinding and repair field. However, common cotton wick cutter grinding and repair devices rely solely on mechanical grinding, resulting in poor grinding and repair effects. They lack effective chemical pretreatment steps, and loading and unloading require machine shutdown, making continuous production impossible. A single clamping operation can only grind one side of the blade, and grinding multiple blades requires repeated clamping, leading to low efficiency. During the grinding process, the grinding disc and the blade are in prolonged contact and friction, which can cause the temperature to rise continuously, resulting in blade annealing and a decrease in hardness, affecting the tool's service life and grinding accuracy. This restricts the efficiency and quality of cotton wick cutter grinding and repair, and also limits the application effect of CMP technology in the field of tool repair.

[0003] To address the above problems, this invention proposes an automatic grinding and repair device and method for cotton core outer cutter. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of common cotton wick outer cutter grinding and repair devices that rely solely on mechanical grinding, resulting in poor grinding and repair effects, lack of effective chemical pretreatment steps, and the need for machine shutdown during loading and unloading, making continuous production impossible. Furthermore, each clamping operation can only grind one side of the blade, requiring repeated clamping for grinding multiple blades, leading to low efficiency. Additionally, the prolonged contact and friction between the grinding disc and the blade during grinding can cause a continuous rise in temperature, resulting in blade annealing, decreased hardness, and reduced tool life and grinding accuracy. Therefore, this invention proposes an automatic grinding and repair device and method for cotton wick outer cutters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, the transmission assembly includes two fixed frames, one of which is equipped with a first motor. The output shaft of the first motor is fixedly connected to a conveying cylinder. The conveying cylinder is rotatably mounted on the fixed frame via two bearings. The magnetic plate is fixedly connected to the conveying cylinder, and two second magnetic strips are mounted on the magnetic plate.

[0010] Preferably, the soaking assembly includes two mounting bases, which are fixedly connected to a fixed frame. An electric push rod is mounted on the mounting base, and a box plate is fixedly connected to the telescopic end of the electric push rod. A rack is fixedly connected above the box plate, and a soaking tank is fixedly connected between the two box plates.

[0011] Preferably, the clamping assembly includes two rotating shafts, which are rotatably mounted on a fixed plate via bearings. The fixed plate is fixedly connected to the conveying cylinder. A first gear is fixedly connected to one end of each rotating shaft, and the rack can mesh upward with the first gear.

[0012] Preferably, a clamping structure is fixedly connected between the two rotating shafts. The clamping structure clamps the cotton core outer cutter. Two first magnetic strips are installed on both sides of the clamping structure, and the first magnetic strips are magnetically connected to the second magnetic strips.

[0013] Preferably, the steering control assembly includes a fixed base, which is fixedly connected to a fixed frame. An electric cylinder is mounted on the fixed base, and a toothed plate is fixedly connected to the telescopic end of the electric cylinder. The toothed plate is capable of meshing downward with a first gear.

[0014] Preferably, the adjustment assembly includes two electric telescopic rods, which are respectively mounted on two fixed frames. The telescopic ends of the two electric telescopic rods are fixedly connected to brackets, and the brackets are provided with a chain transmission structure.

[0015] Preferably, the grinding assembly includes a second motor and three belt rollers. An auxiliary wheel is provided on one side of the second motor, and the auxiliary wheel slides in a slide rail. The slide rail is fixedly connected between two fixed frames. The second motor is mounted on a chain transmission structure by a fixing member. The output shaft of the second motor is fixedly connected to a grinding frame. A smooth plate is fixedly connected to the grinding frame. The three belt rollers are rotatably mounted on the grinding frame by bearings, and a grinding belt is drivenly connected to the three belt rollers. The smooth plate supports the grinding surface of the grinding belt.

[0016] One end of one of the rollers is fixedly connected to a second gear, which meshes with a gear ring. The gear ring is fixedly connected to a second motor via a fixing rod, and the grinding frame is rotatably mounted on the gear ring via a bearing.

[0017] Preferably, the cooling component includes a water tank, which is mounted on a second motor via an installation component. The water tank is connected to a water pump, which is connected to a nozzle assembly. The nozzle assembly is provided with multiple nozzles, which are tilted to ensure that the spray angle accurately corresponds to the grinding belt.

[0018] A method for using an automatic grinding and repair device for cotton core outer cutter includes the following steps:

[0019] S1. During the grinding of the cotton core outer cutter, the cotton core outer cutter is positioned by the clamping structure. Then, the first motor drives the conveying cylinder to rotate, so that the cotton core outer cutter moves to the lower position. At this time, the electric push rod pushes the box plate to move, so that the rack moves upward and drives the first gear. The first gear drives the rotating shaft and the clamping structure to rotate, so that the first magnetic strip is separated from the second magnetic strip, and the cotton core outer cutter automatically hangs down to correspond to the soaking tank. At this time, the tooth segment of the rack separates from the first gear, and the soaking tank moves upward, so that the blade of the cotton core outer cutter is immersed in the chemical agent. During the soaking process, the new cotton core outer cutter is positioned.

[0020] S2. After soaking, the electric push rod returns to its original position, causing the soaking tank to detach from the cotton core outer cutter. Then, the toothed rod drives the first gear downward, causing the clamping structure to rotate and the first and second magnetic strips to attract and position the clamping structure. The cotton core outer cutter continues to be conveyed, allowing the new cotton core outer cutter to be soaked in the chemical agent again. When the cotton core outer cutter is conveyed upward to the grinding area, the electric telescopic rod drives the bracket to move downward, causing the grinding belt of the grinding assembly to contact the blade of the cotton core outer cutter. At this time, the second motor drives the grinding frame to rotate, causing the grinding belt to rotate for grinding. The second gear drives the gear ring, causing the belt roller to drive the grinding belt to circulate, thereby changing the grinding surface for grinding.

[0021] S3. When cooling is required, a water pump draws cooling water to atomize the water in the nozzle assembly and cool the grinding belt. When switching to edge grinding, the adjusting component moves the grinding component upward to reset. At the same time, the chain transmission structure moves the grinding component to one side and separates it from the cotton core outer cutter. At this time, the electric cylinder drives the toothed plate and the first gear to rotate the clamping structure, so that the first magnetic strip and the second magnetic strip on the other side are attracted to each other, ensuring the stability of the clamping structure. At this time, the chain transmission structure smoothly adjusts the grinding belt to correspond with the cotton core outer cutter. Then, the grinding operation is performed again. After grinding, the cotton core outer cutter is moved to the initial clamping position. Then, the cotton core outer cutter is removed and a new cotton core outer cutter is repositioned to perform the next round of grinding operation.

[0022] Compared with the prior art, the present invention provides an automatic grinding and repair device and method for cotton core outer cutter, which has the following beneficial effects:

[0023] 1. The automatic grinding and repair device and method for cotton core outer cutters involves conveying the cotton core outer cutter to the soaking area via a transmission component. The soaking component then chemically soaks the cotton core outer cutter, softening the oxide and wear layers on the blade surface through chemical action, laying the foundation for subsequent mechanical grinding. Combined with the synergistic effect of the grinding component, the chemical mechanical polishing process is fully realized, significantly improving the precision and effect of the grinding and repair. Furthermore, the transmission component allows for continuous feeding, soaking, and grinding operations, achieving continuous processing. The steering control component drives the clamping component to rotate, enabling the grinding and repair of both sides of the cotton core outer cutter's blade surface to be completed in a single clamping operation. Multiple cotton core outer cutters can be continuously and automatically ground and repaired simultaneously, significantly reducing the number of clamping operations and downtime.

[0024] 2. The automatic grinding and repair device and method for cotton core outer cutter uses a second motor to drive the grinding frame to rotate, causing the grinding belt to rotate for grinding operations. The rotation of the second gear can drive the gear ring, thereby enabling the belt roller to drive the grinding belt to move. This automatically switches the contact position between the grinding area and the cotton core outer cutter blade, ensuring that the grinding area that has finished grinding with the blade separates from the blade in a timely manner. After the friction contact is broken, the area can cool down quickly and naturally. With the help of a cooling component, the cooling effect can be further improved, avoiding the continuous temperature rise caused by prolonged contact and friction between the grinding area and the blade. This effectively prevents problems such as annealing, decreased hardness, and deformation of the blade, ensuring the original performance and grinding accuracy of the cotton core outer cutter. At the same time, the cooled grinding belt can participate in grinding again, ensuring the stability and continuity of the grinding process.

[0025] 3. The automatic grinding and repair device and method for cotton core outer cutters utilizes a transmission component to transfer the cotton core outer cutter to the soaking zone. The soaking component smoothly transmits power to the clamping component, immersing the cotton core outer cutter in the chemical reagents of the soaking tank. Subsequently, a steering control component switches the blade surface, and the grinding component automatically switches between grinding surfaces. Uniform wear of the blade during continuous grinding ensures contact stability during grinding belt switching, preventing untimely cooling due to uneven blade wear. Automatic grinding belt switching, combined with a cooling component, prevents high temperatures from damaging the chemical pretreatment effect and affecting grinding accuracy. It also ensures smooth continuous grinding, avoiding the need to stop for cooling due to excessive temperature, further improving continuous production efficiency. The synergistic combination of these two methods leverages the advantages of chemical mechanical polishing, improving both grinding and repair accuracy and efficiency while protecting the tool's performance.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example 1: Refer to Figures 1-6 An automatic grinding and repair device for cotton core outer cutter includes a pretreatment mechanism 100, on which a grinding and repair mechanism 200 is provided;

[0040] The pretreatment mechanism 100 includes a base 101, and a transmission assembly 103 is arranged above the base 101. The transmission assembly 103 includes two fixed frames 1031, one of which is equipped with a first motor 1032. The output shaft of the first motor 1032 is fixedly connected to a conveying cylinder 1033. The first motor 1032 drives the conveying cylinder 1033 to rotate, causing the clamping assembly 105 to drive the cotton core outer cutter for transmission, facilitating the sequential soaking and grinding operations of the cotton core outer cutter. The conveying cylinder 1033 is rotatably mounted on the fixed frame 1031 via two bearings. A magnetic plate 104 is fixedly connected to the conveying cylinder 1033, and two second magnetic strips 107 are installed on the magnetic plate 104. Two steering control assemblies 106 are arranged above the transmission assembly 103. The steering control assembly 106 includes a fixed base 1062. An electric cylinder 1063 is mounted on a fixed base 1062 and a toothed plate 1061 is fixedly connected to the telescopic end of the electric cylinder 1063. The toothed plate 1061 can mesh downward with the first gear 1051. An immersion assembly 102 is provided below the transmission assembly 103. The immersion assembly 102 includes two mounting bases 1025, which are fixedly connected to the fixed base 1031. An electric push rod 1022 is mounted on the mounting base 1025. A box plate 1023 is fixedly connected to the telescopic end of the electric push rod 1022. A rack 1024 is fixedly connected above the box plate 1023. An immersion tank 1021 is fixedly connected between the two box plates 1023. The immersion tank 1021 contains chemical agents, which can be alkaline degreasing agents. This allows the cotton core outer cutter to be immersed in the chemical agents, improving the effect of subsequent grinding and repair.

[0041] The transmission assembly 103 is provided with multiple clamping assemblies 105 and multiple sets of magnetic plates 104. Each clamping assembly 105 includes two rotating shafts 1053, which are rotatably mounted on a fixed plate 1052 via bearings. The fixed plate 1052 is fixedly connected to the conveying cylinder 1033. A first gear 1051 is fixedly connected to one end of each rotating shaft 1053, and a rack 1024 can mesh upwards with the first gear 1051. A clamping structure 1054 is fixedly connected between the two rotating shafts 1053. The clamping structure 1054 clamps the cotton core outer cutter. Two first magnetic strips 1055 are installed on both sides. The first magnetic strips 1055 and the second magnetic strips 107 are magnetically connected. By switching the first magnetic strips 1055 and the second magnetic strips 107 to engage, the overall stability can be ensured after the cotton core outer cutter is switched. The magnetic plate 104 can also play a stable supporting role, ensuring that the cotton core outer cutter can be ground and repaired stably. There are two magnetic plates 104 in each set, located on both sides of the clamping assembly 105. The clamping assembly 105 is automatically changed by the rotation control assembly 106 and the clamping assembly 105.

[0042] The grinding and repair mechanism 200 includes an adjustment component 201, which includes two electrically operated telescopic rods 2012. The two telescopic rods 2012 are respectively mounted on two fixed brackets 1031. The electric telescopic rods 2012 can push the grinding component 202 downwards to smoothly contact the cotton core outer cutter, facilitating the grinding and repair operation. The telescopic ends of the two electric telescopic rods 2012 are fixedly connected to brackets 2011. A chain transmission structure 2013 is provided on the brackets 2011. The position of the grinding component 202 can be adjusted so that the position of the grinding component 202 is offset from that of the cotton core outer cutter, thereby providing room for the rotation of the cotton core outer cutter. Moreover, the chain transmission structure 2013 can adjust the position of the grinding belt 2026 so that the grinding belt 2026 can smoothly correspond to the adjusted cotton core outer cutter. The grinding component 202 is provided on the adjusting component 201, and the cooling component 203 is provided on the grinding component 202. The grinding component 202 can automatically change its surface during the grinding process of the cotton core outer cutter.

[0043] In this embodiment: the cotton core outer cutter is transported to the soaking area by the transmission component 103. At this time, the electric push rod 1022 drives the rack 1024 upward to drive the first gear 1051, so that the clamping component 105 drives the cotton core outer cutter downward automatically, so that it can smoothly enter the soaking tank 1021 for chemical soaking. Through chemical action, the oxide layer and wear layer on the blade surface are softened, laying the foundation for subsequent mechanical grinding. With the synergistic effect of the grinding component 202, the chemical mechanical polishing process is fully realized, significantly improving the accuracy and effect of grinding and repair. Moreover, through the cyclic transmission of the transmission component 103, the feeding, soaking and grinding operations can be carried out continuously to realize continuous processing. Furthermore, through the electric telescopic rod 2012 driving the toothed plate 1061 and the first gear 1051, the holding component can drive the cotton core outer cutter to turn and switch the blade surface, so that the grinding and repair of both sides of the blade surface of the cotton core outer cutter can be completed in a single clamping. Multiple cotton core outer cutters can be continuously and automatically ground and repaired at the same time, greatly reducing the number of clamping times and downtime.

[0044] Example 2: Refer to Figures 6-10An automatic grinding and repair device for cotton core outer cutter includes a grinding assembly 202, which comprises a second motor 2021 and three belt rollers 2027. Side guards can be provided on both sides of the belt rollers 2027 to limit the grinding belt 2026, preventing it from detaching and ensuring stable grinding operation. An auxiliary wheel 2022 is provided on one side of the second motor 2021, sliding in a slide rail 2029. The sliding of the auxiliary wheel 2022 in the slide rail 2029 ensures smooth adjustment of the second motor 2021. The slide rail 2029 is fixedly connected between two fixed frames 1031. The second motor 2021 is mounted on a chain transmission structure 2013 via a fixing component. The output shaft of the second motor 2021 is fixedly connected to a grinding frame 2025. A smooth plate 2028 is fixedly connected to the 2025. The smooth plate 2028 supports the grinding belt 2026, ensuring the grinding and repair effect of the grinding belt 2026 on the outer cutter of the cotton core. The smooth plate 2028 can be made of polytetrafluoroethylene, which can reduce the frictional resistance of the grinding belt 2026. Three belt rollers 2027 are rotatably mounted on the grinding frame 2025 through bearings, and the grinding belt 2026 is drivenly connected to the three belt rollers 2027. The smooth plate 2028 supports the grinding surface of the grinding belt 2026. One end of one belt roller 2027 is fixedly connected to a second gear 2023. The second gear 2023 meshes with a gear ring 2024. The gear ring 2024 is fixedly connected to the second motor 2021 through a fixing rod. The grinding frame 2025 is rotatably mounted on the gear ring 2024 through bearings.

[0045] The cooling component 203 includes a water tank 2031, which is mounted on the second motor 2021 via a mounting bracket. The water tank 2031 is connected to a water pump 2032, which can draw cooling water and atomize it through a nozzle assembly 2033. This ensures that the atomized water droplets are evenly attached to the grinding belt 2026 for water cooling. Moreover, after atomization, the cooling water is not wasted. At the same time, the water cooling operation can be carried out as needed. The water pump 2032 is connected to the nozzle assembly 2033, which is equipped with multiple nozzles. By tilting the multiple nozzles, the spray angle is precisely aligned with the grinding belt 2026.

[0046] In this embodiment: the second motor 2021 drives the grinding frame 2025 to rotate, causing the grinding belt 2026 to rotate for grinding. The rotation of the second gear 2023 can drive the gear ring 2024, thereby enabling the belt roller 2027 to drive the grinding belt 2026 to move. This allows for automatic switching of the contact position between the grinding area and the outer cutting edge of the cotton core, ensuring that the grinding area that has finished grinding with the blade separates from the blade in a timely manner. After the frictional contact is broken, the area can cool down quickly and naturally. Combined with the cooling component 203, the cooling effect can be further improved, avoiding the continuous temperature rise caused by prolonged contact and friction between the grinding area and the blade. This effectively prevents problems such as annealing, decreased hardness, and deformation of the blade, ensuring the original performance and grinding accuracy of the outer cutting edge of the cotton core. At the same time, the cooled grinding belt 2026 can participate in grinding again, ensuring the stability and continuity of the grinding process.

[0047] Example 3: Reference Figures 1-6 An automatic grinding and repair device for cotton core outer cutter includes a pretreatment mechanism 100. The pretreatment mechanism 100 includes a base 101. A transmission component 103 is arranged above the base 101. Two steering control components 106 are arranged above the transmission component 103. An soaking component 102 is arranged below the transmission component 103. Multiple clamping components 105 and multiple sets of magnetic plates 104 are arranged on the transmission component 103. Each set of magnetic plates 104 consists of two plates and is located on both sides of the clamping component 105. The device is driven by the steering control components 106 and the clamping components 105, so that the clamping components 105 automatically change the blade surface of the cotton core outer cutter.

[0048] The grinding and repair mechanism 200 includes an adjustment component 201, a grinding component 202 is provided on the adjustment component 201, a cooling component 203 is provided on the grinding component 202, and the grinding component 202 can automatically change sides during the grinding process of the cotton core outer cutter.

[0049] In this embodiment: the cotton core cutter is transferred to the soaking area via the transmission component 103, while the soaking component 102 can smoothly drive the clamping component 105, immersing the cotton core cutter in the chemical agent of the soaking tank 1021. Subsequently, the blade surface is switched via the steering control component 106, and the grinding component 202 can automatically switch grinding surfaces. The uniform wear of the blade during continuous grinding ensures the contact stability of the grinding belt 2026 during switching, avoiding untimely cooling due to uneven blade wear. The automatic switching of the grinding belt 2026, combined with the cooling component 203, avoids the damage of high temperature to the chemical pretreatment effect, prevents the blade from being affected by high temperature in terms of grinding accuracy, and ensures the smooth progress of the continuous grinding process, avoiding the need to stop the machine for cooling due to excessive temperature, further improving continuous production efficiency. The combination of the two and the advantages of chemical mechanical polishing not only improves the grinding repair accuracy and efficiency, but also protects the performance of the cutting tool.

[0050] A method for using an automatic grinding and repair device for cotton core outer cutter includes the following steps:

[0051] S1. During the grinding of the cotton core outer cutter, the cotton core outer cutter is positioned by the clamping structure 1054. Then, the first motor 1032 drives the conveying cylinder 1033 to rotate, causing the cotton core outer cutter to move downward. At this time, the electric push rod 1022 pushes the box plate 1023 to move, causing the rack 1024 to move upward and drive the first gear 1051. The first gear 1051 drives the rotating shaft 1053 and the clamping structure 1054 to rotate, causing the first magnetic strip 1055 to disengage from the second magnetic strip 107, causing the cotton core outer cutter to automatically droop down and correspond to the soaking tank 1021. At this time, the tooth segment of the rack 1024 separates from the first gear 1051, and the soaking tank 1021 moves upward, causing the blade of the cotton core outer cutter to be immersed in the chemical agent. During the soaking process, the new cotton core outer cutter is positioned.

[0052] S2. After soaking, the electric push rod 1022 returns to its original position downwards, causing the soaking tank 1021 to disengage from the cotton core outer cutter. Then, the rack moves downwards and drives the first gear 1051, causing the clamping structure 1054 to rotate. This causes the first magnetic strip 1055 and the second magnetic strip 107 to attract and position the clamping structure 1054. The cotton core outer cutter continues to be conveyed, allowing the new cotton core outer cutter to be soaked in the chemical agent again. When the cotton core outer cutter is conveyed upwards to the grinding area, the electric telescopic rod 2012 drives the bracket 2011 to move downwards, causing the grinding belt 2026 of the grinding assembly 202 to contact the blade of the cotton core outer cutter. At this time, the second motor 2021 drives the grinding frame 2025 to rotate, causing the grinding belt 2026 to rotate for grinding. The second gear 2023 drives the gear ring 2024, causing the belt roller 2027 to drive the grinding belt 2026 to circulate, thereby changing the grinding surface for grinding.

[0053] S3. When cooling is required, the water pump 2032 draws cooling water, which is then atomized by the nozzle assembly 2033 to cool the grinding belt 2026. When it is necessary to switch the blade surface grinding, the adjusting component 201 drives the grinding component 202 to reset upwards. At the same time, the chain transmission structure 2013 drives the grinding component 202 to move to one side and separate it from the cotton core outer cutter. At this time, the electric cylinder 1063 drives the toothed plate 1061 and the first gear 1051 to drive the clamping structure 1054 to rotate, so that the first magnetic strip 1055 and the second magnetic strip 107 on the other side can be attracted to each other, ensuring the stability of the clamping structure 1054. At this time, the chain transmission structure 2013 smoothly adjusts the grinding belt 2026 to correspond with the cotton core outer cutter. Then, the grinding operation is performed again. After grinding, the cotton core outer cutter is moved to the initial clamping position. Then, the cotton core outer cutter is removed and a new cotton core outer cutter is repositioned to perform the next round of grinding operation.

[0054] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. The method of using the automatic grinding and repair device for cotton core outer cutter according to claim 9, characterized in that, Includes the following steps: S1. When grinding the cotton core outer cutter, the cotton core outer cutter is positioned by the clamping structure (1054). Then, the first motor (1032) drives the conveying cylinder (1033) to rotate, so that the cotton core outer cutter moves to the bottom. At this time, the electric push rod (1022) pushes the box plate (1023) to move, so that the rack (1024) drives the first gear (1051) upward. The first gear (1051) drives the rotating shaft (1053) and the clamping structure (1054) to rotate, so that the first magnetic strip (1055) disengages from the second magnetic strip (107), so that the cotton core outer cutter automatically hangs down and corresponds to the soaking tank (1021). At this time, the tooth segment of the rack (1024) separates from the first gear (1051), and the soaking tank (1021) moves upward, so that the blade of the cotton core outer cutter is immersed in the chemical agent. During the soaking process, the new cotton core outer cutter is positioned. S2. After soaking, the electric push rod (1022) returns to its original position downwards, causing the soaking tank (1021) to disengage from the cotton core outer cutter. Then, the rack moves downwards and engages with the first gear (1051), causing the clamping structure (1054) to rotate. This causes the first magnetic strip (1055) and the second magnetic strip (107) to attract and position the clamping structure (1054). The cotton core outer cutter then continues to be conveyed, allowing a new cotton core outer cutter to be soaked in the chemical agent again. When the cotton core outer cutter is conveyed upwards to the grinding area, the electric extension... The retractor (2012) drives the bracket (2011) to move downward, so that the grinding belt (2026) of the grinding assembly (202) contacts the blade of the cotton core outer cutter. At this time, the second motor (2021) drives the grinding frame (2025) to rotate, so that the grinding belt (2026) rotates to perform grinding operations. The second gear (2023) and the gear ring (2024) drive the belt roller (2027) to drive the grinding belt (2026) to circulate, thereby changing the grinding surface to perform grinding operations. S3. When cooling is required, cooling water is drawn by the water pump (2032) and the nozzle assembly (2033) atomizes the cooling water to cool the grinding belt (2026). When it is necessary to switch the blade grinding, the adjusting component (201) drives the grinding component (202) to reset upward. At the same time, the chain transmission structure (2013) drives the grinding component (202) to move to one side and separate it from the cotton core outer cutter. At this time, the electric cylinder (1063) drives the toothed plate (1061) and the first gear (1051) to transmit... The movement causes the clamping structure (1054) to turn, so that the first magnetic strip (1055) on the other side and the second magnetic strip (107) can be attracted together, ensuring the stability of the clamping structure (1054). At this time, the chain transmission structure (2013) smoothly adjusts the grinding belt (2026) to correspond with the cotton core outer cutter, and then the grinding operation is carried out again. After grinding, the cotton core outer cutter is moved to the initial clamping position, and then the cotton core outer cutter is removed and the new cotton core outer cutter is repositioned to carry out the next round of grinding operation.
