Description

Technical Field

[0001] This invention relates to the field of rolling mill processing technology, specifically to a grinding and polishing device and method for stainless steel rolling mills. Background Technology

[0002] Generally speaking, a roll grinding and polishing device is a piece of equipment used for stainless steel processing and precision surface treatment of rolls. During the roll processing, rough grinding, fine grinding and polishing are required in sequence to remove the processing allowance on the roll surface, adjust the roll shape accuracy and improve the surface finish, so as to ensure that the roll surface quality is stable, not easy to stick to the material and has a long service life during the stainless steel rolling process.

[0003] In actual processing, the rough grinding and fine grinding processes usually require the use of coolant for cooling and chip removal, and a dust removal mechanism to remove grinding dust. During this process, coolant, oil, and fine grinding debris easily adhere to the surface of the roll. If it directly enters the next processing step, the residual impurities will form scratches and pits during grinding or polishing, seriously affecting the surface quality. Therefore, the surface of the roll must be thoroughly cleaned before transitioning from rough grinding to fine grinding and from fine grinding to polishing. However, existing grinding and polishing devices require the roll to be completely disassembled from the clamping and fixing mechanism of the equipment and then transported to a separate station for manual or offline cleaning. After cleaning, it is re-clamped and positioned. This method not only significantly increases the loading, unloading, and transportation time and reduces processing efficiency, but also damages the original positioning accuracy of the roll due to repeated disassembly and reassembly, resulting in deviations in coaxiality and straightness. Consequently, surface scratches, spots, and other defects occur during subsequent polishing, affecting the finished roll yield. Based on this, the present invention aims to provide a grinding and polishing device and method for stainless steel processing rolls that can achieve online cleaning between processes, improve processing accuracy and work efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a grinding and polishing device and method for stainless steel processing rolls, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A stainless steel processing roll grinding and polishing device, comprising: The mounting base has a connecting plate, a fixing frame, and a cleaning frame fixedly mounted on its bottom from left to right. A rotating arm is rotatably mounted on the bottom end of the fixing frame. The rotating arm is driven to rotate by a first drive source. A roller is rotatably mounted on one end of the rotating arm. The roller is connected to the rotating arm through a clamping assembly. A grinding station is located below the connecting plate, and a cleaning station is located below the cleaning frame. The roller is subjected to coarse grinding, fine grinding, and polishing at the grinding station. The first drive source drives the rotating arm to rotate 180 degrees, allowing the roller to switch between the grinding station and the cleaning station. A movable table is slidably mounted on a cleaning rack. The movable table is driven to move by a first output source. The movable table reciprocates along the axis of the roller. A lifting rod is slidably mounted on the movable table. A base plate is fixedly mounted at the bottom end of the lifting rod. Cleaning cotton is mounted on the bottom of the base plate. The lifting rod is driven to rise and fall by a linkage component. When the roller is in the cleaning station, the linkage component drives the lifting rod to fall, so that the cleaning cotton abuts against the outer surface of the roller. The cleaning pipe is fixedly installed on one side of the cleaning frame. The water inlet of the cleaning pipe is connected to an external water supply tank, and the water outlet of the cleaning pipe faces the edge where the cleaning cotton abuts against the roller. A drying assembly is located on the side of the washing rack away from the washing pipe. The air outlet of the drying assembly faces the bottom of the roller and the washing cotton. The drying assembly is connected to the linkage assembly.

[0006] As a further embodiment of the present invention: the clamping assembly includes a rotating disk and clamping plates. Two symmetrically arranged rotating disks are rotatably mounted on one end of a rotating arm. One of the rotating disks is driven to rotate by a second drive source fixedly mounted on the rotating arm. Two symmetrically arranged clamping plates are slidably mounted on the rotating disk. The clamping plates are driven to move in opposite directions by a second output source. The two clamping plates are used to clamp and fix one end of the roll.

[0007] As a further embodiment of the present invention: the linkage component includes a spring, a U-shaped frame, rollers, a triangular block, a bevel, and a drive component. The bottom of the moving platform is connected to the top of the base plate via a spring. The preload of the spring causes the base plate to descend. The U-shaped frame is fixedly installed on the top of the lifting rod. The rollers are rotatably installed on the top of the U-shaped frame. There is a through hole between the rollers and the U-shaped frame. The triangular block is slidably installed on the cleaning rack. The triangular block is slidably inserted into the through hole. The triangular block is driven to move by the drive component. The bevel is formed on the triangular block. The bevel is inclined. When the drive component drives the triangular block to move to the end away from the moving platform, the horizontal height of the bevel near the moving platform is lower than the horizontal height of the bevel away from the moving platform.

[0008] As a further embodiment of the present invention: the drive assembly includes a threaded rod and a sliding frame, the threaded rod is rotatably mounted on one side of the cleaning frame, the sliding frame is slidably mounted on the cleaning frame, the sliding frame is fixedly connected to the triangular block, and the sliding frame is threadedly connected to the threaded rod.

[0009] As a further aspect of the present invention: the drying component includes a connecting frame and a second high-pressure air outlet. The connecting frame is fixedly installed on the sliding frame, and the second high-pressure air outlet is rotatably installed on the connecting frame. The second high-pressure air outlet is connected to the high-pressure air tank. When the linkage component drives the lifting rod to rise, the bottom plate and the cleaning cotton rise synchronously. At this time, the connecting frame moves synchronously, so that the air outlet of the second high-pressure air outlet faces the bottom of the cleaning cotton.

[0010] As a further embodiment of the present invention: the drying assembly further includes a side platform, a sliding seat, and a first high-pressure air outlet. The side platform is disposed on the side of the cleaning frame away from the fixed frame. The sliding seat is slidably mounted on the side platform. The sliding seat is driven to move by a third output source. The sliding seat reciprocates along the axis of the roller. The first high-pressure air outlet is rotatably mounted on the sliding seat. The first high-pressure air outlet is connected to a high-pressure air tank. When the roller is in contact with the cleaning cotton, the outlet of the first high-pressure air outlet faces the outer surface of the roller.

[0011] As a further aspect of the present invention: three staggered axial displacement platforms are provided in the grinding station, and all three axial displacement platforms are fixedly installed on the connecting plate. A grinding table is slidably installed on each axial displacement platform, and a grinding assembly is provided on the grinding table. The three grinding assemblies are respectively used for rough grinding, fine grinding and polishing of the roll. A cooling pipe is fixedly installed on the connecting plate, and the inlet of the cooling pipe is connected to a coolant storage tank. When the roll is located in the grinding station, the outlet of the cooling pipe faces the outer surface of the roll.

[0012] A method for grinding and polishing stainless steel processing rolls, the method being applied to a stainless steel processing roll grinding and polishing apparatus as described above, the method comprising the following steps: Step S1: The roll to be processed is clamped and fixed to one end of the rotating arm by the clamping assembly. At this time, the device is in the initial state. The rotating arm is positioned at the grinding station by the first drive source. The roll is located below the connecting plate. The moving table is stored at the end of the cleaning frame. The lifting rod is in the high position. The cleaning tube and the drying assembly are in the standby state. The outer circle surface of the roll is rough ground in sequence. Cooling and dust removal are carried out in conjunction with the processing. Step S2: After rough grinding is completed, start the first drive source to drive the rotating arm to rotate 180 degrees, and drive the roll to switch from the grinding station to the cleaning station below the cleaning frame, keeping the original clamping and positioning state of the roll unchanged. Step S3: Start the linkage component to drive the lifting rod to descend, causing the base plate and cleaning cotton to move down synchronously, so that the cleaning cotton presses against the outer surface of the roller. Turn on the cleaning pipe to supply cleaning fluid, and the cleaning fluid is continuously sprayed to the edge where the cleaning cotton and the roller meet. Step S4: Start the first output source to drive the moving table to move back and forth along the axis of the roll, and cooperate with the rotation of the roll. Use cleaning cotton to thoroughly clean the surface of the roll to remove the adhering coolant, wear debris and impurities, so as to achieve online cleaning of the roll. Step S5: After cleaning is completed, turn off the cleaning pipe, start the drying component, and use the air outlet to blow and dry the roller and cleaning cotton under high pressure. After the roller surface is completely dry, rotate the rotating arm again to return the roller to the grinding station, and then perform the fine grinding, cleaning and drying and polishing process in sequence.

[0013] The beneficial effects of this invention are: 1. In this invention, by integrating the grinding and cleaning stations onto the same mounting base, the roller is driven to seamlessly switch between the two stations by the 180-degree rotation of the rotating arm. This achieves online cleaning and drying of the roller between processes without disassembling the roller and clamping components. This avoids the risk of positioning accuracy deviation caused by frequent disassembly and transfer in traditional offline cleaning methods. It effectively solves the defects such as surface scratches and spots caused by coaxiality and straightness damage in subsequent polishing processes, and significantly improves the finished product qualification rate and surface quality of the roller.

[0014] 2. In this invention, when the rolls are switching positions, the cleaning cotton is automatically raised to avoid interference and collision. During cleaning, the preload of the spring is used to make the cleaning cotton closely adhere to the surface of the rolls. It can also adapt to the change in radial thickness of the rolls caused by grinding, ensuring efficient cleaning in all directions without dead angles, timely removal of residual coolant and grinding debris, and significantly reducing the risk of secondary scratches on the processed surface by impurities.

[0015] 3. In this invention, through the coordinated operation of the drying component and the linkage component, combined with the dual-outlet design of the first and second high-pressure air outlets, the synchronous and comprehensive drying of the roller and the cleaning cotton is achieved. The second high-pressure air outlet moves synchronously with the linkage component, which can specifically dry the arc surface of the cleaning cotton. The first high-pressure air outlet moves back and forth along the roller axis and cooperates with the roller rotation to achieve thorough cleaning of the roller surface without dead corners. This avoids the problem of moisture residue caused by incomplete drying of the roller, and avoids defects such as surface water stains and spots in the subsequent polishing process. This further ensures the processing accuracy and surface smoothness of the roller, while extending the service life of the cleaning cotton and improving the stability of continuous operation of the device.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 As shown, the present invention is a roller grinding and polishing device for stainless steel processing, comprising: Mounting base plate 1, from left to right, has a connecting plate 7, a fixing frame 2, and a cleaning frame 12 fixedly mounted on its bottom. A rotating arm 3 is rotatably mounted on the bottom end of the fixing frame 2. The rotating arm 3 is driven to rotate by a first driving source. A roller 6 is rotatably mounted on one end of the rotating arm 3. The roller 6 is connected to the rotating arm 3 through a clamping assembly. The area below the connecting plate 7 is a grinding station, and the area below the cleaning frame 12 is a cleaning station. The roller 6 is subjected to coarse grinding, fine grinding, and polishing at the grinding station. The first driving source drives the rotating arm 3 to rotate 180 degrees, so that the roller 6 switches between the grinding station and the cleaning station. A movable table 13 is slidably mounted on a cleaning rack 12. The movable table 13 is driven to move by a first output source. The movable table 13 reciprocates along the axis of the roller 6. A lifting rod 14 is slidably mounted on the movable table 13. A base plate 16 is fixedly mounted at the bottom end of the lifting rod 14. A cleaning cotton 17 is mounted at the bottom of the base plate 16. The lifting rod 14 is driven to rise and fall by a linkage component. When the roller 6 is in the cleaning position, the linkage component drives the lifting rod 14 to fall, so that the cleaning cotton 17 abuts against the outer surface of the roller 6. The cleaning pipe 26 is fixedly installed on one side of the cleaning frame 12. The water inlet of the cleaning pipe 26 is connected to the external water supply tank, and the water outlet of the cleaning pipe 26 faces the edge where the cleaning cotton 17 and the roller 6 abut. A drying assembly is located on the side of the cleaning rack 12 away from the cleaning pipe 26. The air outlet of the drying assembly faces the bottom of the roller 6 and the cleaning cotton 17. The drying assembly is connected to the linkage assembly.

[0021] In one embodiment, the first drive source can be a servo motor, a rotary cylinder, or other mechanisms capable of rotational motion. The first output source can be a belt reciprocating mechanism or other mechanisms capable of linear reciprocating motion. This embodiment does not impose specific limitations on these components. The working principle of this invention: The device is in an initial standby state, the rotating arm 3 is positioned at the grinding station by the first drive source, the roller 6 is located below the connecting plate 7, the moving table 13 is stored at the end of the cleaning frame 12, the lifting rod 14 is in a high position, the cleaning pipe 26 and the drying component are both in standby state, and the three grinding components 10 are all in a retracted avoidance state; During operation, the roller 6 to be processed is first clamped and fixed to one end of the rotating arm 3 by the clamping component. After clamping is completed, the axial displacement table 8 corresponding to the rough grinding process is started, driving the grinding table 9 where the rough grinding component is located to approach the roller 6, so that the rough grinding component contacts the outer surface of the roller 6. At the same time, the second drive source is started to drive the roller 6 to rotate at a uniform speed, and the cooling pipe 11 is started. The coolant is continuously sprayed to the contact area between the roller 6 and the rough grinding component to achieve cooling and chip removal, thus completing the rough grinding process; After rough grinding is completed, the axial displacement table 8 corresponding to rough grinding drives the grinding table 9 to retract and avoid it. The first drive source is started to drive the rotating arm 3 to rotate downward by 180 degrees, which drives the roller 6 to switch from the grinding station to the cleaning station below the cleaning frame 12. The original clamping and positioning state of the roller 6 remains unchanged. The linkage component is started to drive the lifting rod 14 to descend, which drives the base plate 16 and the cleaning cotton 17 to move down synchronously, so that the cleaning cotton 17 presses against the outer surface of the roller 6. The cleaning pipe 26 is turned on to supply cleaning fluid. The cleaning fluid is continuously sprayed to the edge where the cleaning cotton 17 and the roller 6 come into contact. The first output source is started to drive the moving table 13 to move back and forth along the axis of the roller 6. In coordination with the rotation of the roller 6, the cleaning cotton 17 thoroughly brushes the surface of the roller 6 to remove the adhering coolant, grinding debris and impurities, so as to achieve online cleaning of the roller 6. After cleaning, the cleaning pipe 26 is closed, and the drying assembly is started. The air outlet blows and dries the roller 6 and cleaning cotton 17 under high pressure. After the surface of the roller 6 is completely dry, the first drive source is started again to drive the rotating arm 3 to rotate 180 degrees, turning the roller 6 back to the grinding station. The axial displacement stage 8 corresponding to the fine grinding process is started, driving the fine grinding assembly to approach the roller 6. The above process of coarse grinding, cleaning, and drying is repeated to complete the fine grinding process. After the fine grinding is completed, the same process is followed to switch to the polishing assembly to complete the polishing process. After polishing is completed, the clamping assembly releases the roller 6 to complete the unloading. All components are reversed and reset, waiting for the next processing cycle. In this way, the roller 6 does not need to be disassembled. The station can be quickly switched by rotating the rotating arm 3. Combined with online cleaning and drying, the problems of offline cleaning being cumbersome and multiple disassembly and assembly damaging the positioning accuracy are avoided. At the same time, the cooling pipe 11 cools and removes chips in real time, the cleaning cotton 17 cleans thoroughly, and the drying assembly dries quickly, effectively reducing surface scratches, pits and other defects caused by residual impurities, improving the finished quality and pass rate of the roller 6. The integrated layout simplifies the equipment structure and greatly improves the processing efficiency.

[0022] like Figures 1-7 As shown, in a preferred embodiment of the present invention, the clamping assembly includes a rotating disk 4 and a clamping plate 5. Two symmetrically arranged rotating disks 4 are rotatably mounted on one end of a rotating arm 3. One rotating disk 4 is driven to rotate by a second drive source fixedly mounted on the rotating arm 3. Two symmetrically arranged clamping plates 5 are slidably mounted on the rotating disk 4. The clamping plates 5 are driven to move in opposite directions by a second output source. The two clamping plates 5 are used to clamp and fix one end of the roll 6.

[0023] In one embodiment, the second drive source can be a servo motor, a rotary cylinder, or other mechanisms capable of rotational motion. The second output source can be a motor-driven bidirectional lead screw assembly or other mechanisms capable of opposite motion. This embodiment does not impose specific limitations on this.

[0024] In practical application, when the roller 6 is installed, the second output source is activated, driving the two clamping plates 5 to move towards each other, clamping and fixing both ends of the roller 6 between the two rotating disks 4, thus achieving a temporary rigid connection between the roller 6 and the rotating disks 4. During the grinding and cleaning process, the second drive source is activated, driving one rotating disk 4 to rotate. Since the roller 6 is rigidly connected to the two rotating disks 4, the other rotating disk 4 rotates synchronously with the roller 6 on the rotating arm 3, thereby driving the roller 6 to rotate at a uniform speed, ensuring that the entire outer surface of the roller 6 can uniformly contact the grinding component 10 or the cleaning cotton 17, ensuring the uniformity of processing and cleaning. The design of the clamping plates 5 moving towards each other can adapt to rollers 6 of different specifications, improving the versatility of the device and avoiding the cumbersome replacement of clamping components required by existing devices. At the same time, the clamping is firm, preventing the roller 6 from shifting or shaking during rotation, further improving the processing accuracy.

[0025] like Figures 1-9 As shown in the preferred embodiment of the present invention, the linkage component includes a spring 15, a U-shaped frame 18, a roller 19, a triangular block 27, a bevel 28, and a drive component. The bottom of the moving platform 13 is connected to the top of the base plate 16 via the spring 15. The preload of the spring 15 causes the base plate 16 to descend. The U-shaped frame 18 is fixedly installed on the top of the lifting rod 14. The roller 19 is rotatably installed on the top of the U-shaped frame 18. There is a through hole 20 between the roller 19 and the U-shaped frame 18. The triangular block 27 is slidably installed on the cleaning rack 12. The triangular block 27 is slidably inserted into the through hole 20. The triangular block 27 is driven to move by the drive component. The bevel 28 is formed on the triangular block 27. The bevel 28 is inclined. When the drive component drives the triangular block 27 to move away from the moving platform 13, the horizontal height of the end of the bevel 28 near the moving platform 13 is lower than the horizontal height of the end of the bevel 28 away from the moving platform 13.

[0026] Specifically, the drive assembly includes a threaded rod 29 and a sliding frame 30. The threaded rod 29 is rotatably mounted on one side of the cleaning frame 12, and the sliding frame 30 is slidably mounted on the cleaning frame 12. The sliding frame 30 is fixedly connected to the triangular block 27 and threadedly connected to the threaded rod 29.

[0027] In practical application, when the roller 6 is about to switch to the cleaning station, the drive assembly is activated, the threaded rod 29 rotates, driving the sliding frame 30 to move, which in turn drives the triangular block 27 to insert into the through hole 20 of the U-shaped frame 18. At this time, the inclined side 28 and the roller 19 roll together, pushing the roller 19 to rise, driving the U-shaped frame 18 and the lifting rod 14 to rise, compressing the spring 15, so that the cleaning cotton 17 rises to a suspended state, avoiding the roller 6, and preventing rigid interference between the roller 6 and the cleaning cotton 17 when the roller 6 rotates to switch stations, thus protecting the surface of the roller 6 and the cleaning cotton 17. When the roller 6 switches to the cleaning station and completes the positioning, the drive assembly reverses the drive, driving the triangular block 27 to move out of the through hole 20, releasing the support of the lifting rod 14, and the spring 15 releases the preload, pushing the base plate 16 and the lifting rod 14 to descend vertically, so that the cleaning cotton 17 presses against the outer surface of the roller 6. Since the radial thickness of the roller 6 will become thinner after coarse and fine grinding, the spring 15 can automatically extend and push the base plate 16 down to adapt to the change in the thickness of the roller 6, ensuring that the cleaning cotton 17 is always in close contact with the roller 6, guaranteeing the cleaning effect, without the need for manual adjustment, avoiding the problem that the existing device cannot adapt to the change in the thickness of the roller 6 and the cleaning is not thorough.

[0028] like Figures 1-9 As shown, in a preferred embodiment of the present invention, the drying assembly includes a connecting frame 24 and a second high-pressure air outlet 25. The connecting frame 24 is fixedly installed on the sliding frame 30, and the second high-pressure air outlet 25 is rotatably installed on the connecting frame 24. The second high-pressure air outlet 25 is connected to the high-pressure air tank. When the linkage assembly drives the lifting rod 14 to rise, the bottom plate 16 and the cleaning cotton 17 rise synchronously. At this time, the connecting frame 24 moves synchronously, so that the air outlet of the second high-pressure air outlet 25 faces the bottom of the cleaning cotton 17.

[0029] Specifically, the drying assembly further includes a side platform 21, a sliding seat 22, and a first high-pressure air outlet 23. The side platform 21 is located on the side of the cleaning frame 12 away from the fixed frame 2. The sliding seat 22 is slidably mounted on the side platform 21. The sliding seat 22 is driven to move by a third output source. The sliding seat 22 reciprocates along the axis of the roller 6. The first high-pressure air outlet 23 is rotatably mounted on the sliding seat 22. The first high-pressure air outlet 23 is connected to a high-pressure air tank. When the roller 6 is in contact with the cleaning cotton 17, the outlet of the first high-pressure air outlet 23 faces the outer surface of the roller 6.

[0030] In one embodiment, the third output source can be a motor-driven lead screw reciprocating assembly, or other mechanisms capable of achieving linear reciprocating motion. This embodiment does not impose specific limitations on this.

[0031] In practical application, after cleaning, the linkage component drives the lifting rod 14 to rise, causing the cleaning cotton 17 to detach from the roller 6. At this time, the connecting frame 24 moves synchronously with the sliding frame 30, so that the second high-pressure air nozzle 25 is aligned with the bottom of the cleaning cotton 17. The second high-pressure air nozzle 25 sprays high-pressure gas to thoroughly dry the cleaning cotton 17, preventing residual moisture from affecting the next cleaning effect. At the same time, the third output source is activated to drive the sliding seat 22 to reciprocate along the axis of the roller 6. The first high-pressure air nozzle 23 sprays high-pressure gas, which, in conjunction with the rotation of the roller 6, thoroughly blows and dries the outer surface of the roller 6, ensuring that there is no residual moisture on the surface of the roller 6, and preventing surface defects caused by residual moisture during subsequent polishing. Both the first high-pressure air outlet 23 and the second high-pressure air outlet 25 are adjustable in angle. The second high-pressure air outlet 25 can be adjusted to an upward tilt to dry the curved surface of the cleaning cotton 17, ensuring thorough drying and further improving the synergistic effect of cleaning and drying, thus guaranteeing the processing quality of subsequent polishing processes.

[0032] like Figures 1-3 As shown, in a preferred embodiment of the present invention, during operation, the axial displacement stage 8 for the rough grinding process is first activated, driving the grinding table 9 on the axial displacement stage 8 to move towards the roll 6, so that the corresponding grinding component 10 contacts the outer surface of the roll 6. At the same time, the rotation of the roll 6 and the cooling pipe 11 are activated. The outlet of the cooling pipe 11 faces the outer surface of the roll 6, continuously spraying coolant for cooling and chip removal, completing the rough grinding operation of oxide scale, large-scale machining and initial finishing on the surface of the roll 6. During this process, the other two grinding components 10 for fine grinding and polishing are in a retracted avoidance state with their respective grinding tables 9, maintaining a safe distance from the roll 6 to avoid interference or accidental damage to the surface of the roll 6. Through the staggered arrangement of the three axial displacement stages 8 and the corresponding grinding components 10, the seamless connection and automated switching of the three processes of rough grinding, fine grinding and polishing are realized.

[0033] Please see Figures 1-9 As shown, the present invention provides a method for grinding and polishing stainless steel processing rolls. The method is applied to a stainless steel processing roll grinding and polishing apparatus as described in the above embodiments, and includes the following steps: Step S1: The roller 6 to be processed is clamped and fixed to one end of the rotating arm 3 by the clamping assembly. At this time, the device is in the initial state. The rotating arm 3 is positioned at the grinding station by the first drive source. The roller 6 is located below the connecting plate 7. The moving table 13 is stored at the end of the cleaning frame 12. The lifting rod 14 is in a high position. The cleaning tube 26 and the drying assembly are both in standby state. The outer circle surface of the roller 6 is rough ground in sequence. During the processing, the coolant is used to cool down and remove dust. Step S2: After rough grinding is completed, start the first drive source to drive the rotating arm 3 to rotate 180 degrees, and drive the roller 6 to switch from the grinding station to the cleaning station below the cleaning frame 12 in a synchronous manner, keeping the original clamping and positioning state of the roller 6 unchanged. Step S3: Start the linkage component to drive the lifting rod 14 to descend, which will cause the base plate 16 and the cleaning cotton 17 to move down synchronously, so that the cleaning cotton 17 presses against the outer surface of the roller 6. Turn on the cleaning pipe 26 to supply cleaning liquid, and the cleaning liquid will be continuously sprayed to the edge where the cleaning cotton 17 and the roller 6 come into contact. Step S4: Start the first output source to drive the moving stage 13 to move back and forth along the axis of the roll 6, and cooperate with the rotation of the roll 6. Use the cleaning cotton 17 to thoroughly clean the surface of the roll 6 to remove the adhering coolant, wear debris and impurities, and realize online cleaning of the roll 6. Step S5: After cleaning is completed, close the cleaning pipe 26, start the drying component, and use the air outlet to blow and dry the roller 6 and cleaning cotton 17 under high pressure. After the surface of the roller 6 is completely dry, rotate the rotating arm 3 again to rotate the roller 6 back to the grinding station, and then perform the fine grinding, cleaning and drying and polishing process in sequence.

[0034] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
