Description

Technical Field

[0001] This invention relates to the technical field of stone bridge cutting equipment, specifically to a stone bridge cutting equipment with stress intervention function and its usage method. Background Technology

[0002] Bridge-type stone cutting equipment is the most basic and core general-purpose machinery in the stone processing industry. Its structural feature is that the crossbeam (bridge) is erected on the guide rails on both sides and can move longitudinally, while the spindle head equipped with a high-speed rotating diamond saw blade moves laterally along the crossbeam. Through this "XY" axis linkage, it can achieve straight cutting, chamfering and simple irregular shape processing of large stone slabs such as granite and marble. With its advantages of simple structure, convenient operation, high cutting accuracy and wide range of applications, this equipment is widely used in stone factories for processes such as raw block cutting, slab thickness determination and finished product cutting. It is an indispensable key equipment connecting stone mining and deep processing.

[0003] Application No. 201310070045.1 discloses a bridge-type stone cutting machine with grinding and polishing functions, including a crossbeam, two longitudinal beams, a movable seat, a lifting frame, a worktable, and a cutting device mounted on the lifting frame. A longitudinal moving mechanism is installed between the crossbeam and the longitudinal beams, a transverse moving mechanism is installed between the movable seat and the crossbeam, and a lifting moving mechanism is installed between the lifting frame and the movable seat. The invention is characterized by further including a grinding and polishing device mounted on the lifting frame. The grinding and polishing device includes a spindle box that can be vertically moved up and down on the lifting frame, a spindle vertically arranged on the spindle box, a main motor mounted on the spindle box and connected to drive the spindle rotation, a grinding disc mounted at the lower end of the spindle, and a vertical moving mechanism connected to drive the spindle box to move vertically. This invention can achieve integrated cutting and grinding and polishing, reducing the stone handling and clamping processes between the cutting and grinding equipment, improving stone processing efficiency, and saving labor costs.

[0004] In the field of existing stone bridge cutting technology, although various cutting equipment already exist, the following main technical problems still exist in practical applications: Traditional equipment typically uses a single or a small number of cutting heads for continuous operation. Prolonged high-speed operation can cause the cutting rope (or saw blade) to overheat, wear more rapidly, and even annealing, significantly shortening its service life. Furthermore, existing equipment lacks an automatic replacement mechanism, and replacing cutting units often requires manual operation while the machine is stopped, resulting in low efficiency. Stone generates significant internal stress during the cutting process. Current technology lacks effective stress intervention methods, which can easily lead to the formation and propagation of microcracks at the cutting kerf, causing stone chipping, breakage, or uneven cut surfaces, thus affecting the yield rate. When cutting deep or large slabs, as the gaps deepen, the lack of an effective internal support structure can easily cause the gaps to collapse or close due to the weight of the stone or the release of stress, which can then trap the cutting rope, damage the equipment, or destroy the stone.

[0005] Therefore, we have made improvements to this and proposed a stone bridge-type cutting device with stress intervention function and its usage method. Summary of the Invention

[0006] In view of the problems of traditional equipment being prone to overheating and wear, lack of stress intervention leading to stone cracking, and lack of support to prevent gap collapse in the above-mentioned or existing technologies, this invention is proposed.

[0013] As a preferred embodiment of the stone bridge-type cutting equipment and its usage method with stress intervention function of the present invention, the cleaning unit includes a water storage tank located at the bottom of the main body. The bottom of the adjustment unit and several cutting units are all located in the inner cavity of the water storage tank. A water guide pipe is fixedly installed on the outside of the water storage tank. A water pump is fixedly installed at one end of the water guide pipe. A transmission pipe is fixedly installed at the output end of the water pump. An atomizing nozzle is fixedly installed at one end of the transmission pipe.

[0017] The operating method of stone bridge cutting equipment with stress intervention function includes: Step 1: Check that all components are securely connected and perform pre-operation preparations for each component, including injecting sufficient cooling liquid into the cleaning unit. Step 2: Place the stone to be processed on the conveyor, and the conveyor will move the stone to the cutting position of the cutting unit; Step 3: Start the control unit. The control unit drives a set of cutting units to cut the stone conveyed on the conveyor. The other cutting units, which are at the same horizontal position as the cutting unit responsible for cutting the stone, support the gap in the stone cutting. Step 4: The cleaning unit is activated simultaneously during the stone cutting process. The cleaning unit sprays liquid mist onto the top of the stone being cut, and also washes the surface of the cutting unit and the corresponding stone cutting seams. Step 5: After completing the stone cutting, activate the control unit to disconnect the current cutting unit; Step 6: Start the adjustment unit. The adjustment unit moves the cutting unit in the cutting position toward the water tank on the cleaning section. Then, the liquid inside the water tank is used to soak, cool and clean the cutting unit. After that, the control unit is restarted to connect and drive the replaced cutting unit. Step 7: When the adjustment unit is running, it will drive the circulation component locally. At this time, the circulation pump on the circulation component will be started simultaneously. This will allow liquid exchange between the upper and lower positions of the filter frame inside the cleaning section. In this way, the liquid containing impurities will be transferred to the bottom inner cavity of the filter frame on the water tank, while the clean liquid will be located at the top of the filter frame on the water tank. When the cutting unit is immersed in the top of the filter frame inside the water tank, it will be repeatedly rinsed by the flowing clean liquid and will not be contaminated by residual dirt. Step 8: When the cutting unit in the cutting position is cutting the stone, the descaling component will also be brought into the cutting gap in the stone along with the cutting rope to scrape off the impurities. The scraped impurities will be flushed and cleaned by the flowing liquid inside the water tank. In this way, the impurities in the stone gap can be cleaned repeatedly. Step 9: Equipment cleaning and maintenance. Clean the stone chips on the cutting unit, check the wear of the cutting rope, and replace it if it is severely worn. Clean the stone chips remaining on the filter screen frame, open the drain valve at the bottom of the water tank to drain the sedimented impurities, and replenish the liquid in the water tank. Beneficial effects

[0018] By using shot-peened cutting ropes combined with cutting units to physically support the gaps, stress intervention is effectively achieved, preventing the expansion of micro-cracks in the stone and the collapse of the gaps, and significantly improving the yield and the regularity of the cut surface. The automatic rotation mechanism of the adjustment unit can immediately move the high-temperature and high-wear cutting unit to the cleaning area for soaking and cooling, and replace it with a new unit for work. This avoids overheating and annealing and rapid wear caused by the continuous operation of a single cutting unit for a long time, significantly extending the life of consumables and ensuring continuous operation efficiency. A highly efficient closed-loop cleaning system of "cutting-scraping-rinsing-filtration" has been constructed. The system utilizes the curved plate descaling component on the cutting rope in conjunction with high-pressure liquid flow to remove dirt from crevices without dead angles. It also innovatively uses the power of the equipment to drive the scraper wheel to clean the filter screen and cooperates with the circulation pump to achieve dynamic liquid exchange, ensuring the cleanliness of the coolant and the cooling effect, and eliminating secondary pollution.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example, refer to Figure 1 ——9; This embodiment provides a stone bridge-type cutting device with stress intervention function, which includes: The main body 1 of the stone bridge-type cutting equipment spans across the top of the stone to process it; The conveying unit 2 for moving stone is located at the bottom center of the main body 1 and is used to transport and fix stone. Several stone cutting units 3 are arranged on both sides of the main body 1 to cut stone. One of the cutting units 3 is equipped with a control unit 6 on the outside. The control unit 6 is used to drive the cutting unit 3 to operate, thereby realizing the stone cutting work. Adjustment unit 4 is externally installed with cutting unit 3 and is used to move the position of several cutting units 3. After each stone cutting is completed, adjustment unit 4 can be activated to move the position of cutting unit 3, and then a new cutting unit 3 can be replaced to cut subsequent stones, thus avoiding the long-term operation of the same cutting unit 3. The cleaning unit 5 is located outside the main body 1. It is used to spray liquid onto the stone surface to cool it down. At the same time, the cleaning unit 5 also performs cooling and cleaning treatment on the cutting unit 3.

[0023] The conveying unit 2 includes a base 201 located at the center of the bottom of the main body 1. A drive assembly 202 is mounted on the surface of the base 201. A support base 203 is fixedly mounted on the moving end of the drive assembly 202. The drive assembly 202 is used to drive the support base 203 to move horizontally. The drive assembly 202 can be a lead screw adjustment mechanism. The lead screw adjustment mechanism includes an assembly groove opened at the bottom of the base 201. A drive motor is provided on the inner wall of the assembly groove. A lead screw is fixedly mounted on the output end of the drive motor. A movable block is mounted on one end of the lead screw. The outer wall of the movable block fits against the inner wall of the assembly groove. The assembly groove serves to limit the position of the movable block. At the same time, the surface of the movable block is fixed to the bottom of the support base 203. A lifting assembly 204 is fixedly installed on the top of the support base 203. The lifting assembly 204 can be a mechanism with lifting function, specifically a lifting machine. A bearing plate is fixedly installed on the lifting end of the lifting machine. When stone cutting is required, the stone can be loaded onto the lifting assembly 204 using hoisting equipment. Clamping assemblies 205 are provided on both sides of the lifting assembly 204. The clamping assemblies 205 are used to clamp and fix the stone to be cut, preventing the stone from shaking during the cutting process and causing the stone cutting position to shift, thus improving the accuracy of stone cutting. The clamping assemblies 205 are divided into two groups. Each group of clamping assemblies 205 includes a fixed seat fixed to one side of the bearing plate. A push rod motor is fixedly installed on the top of the fixed seat. A clamping plate is fixedly installed on the moving end of the push rod motor. A rubber protective layer is provided on the surface of the clamping plate, and several anti-slip points are provided on the surface of the protective layer. This allows for fixation and shock absorption when clamping the stone, while also providing an anti-slip function. The cutting unit 3 includes two opposing retaining frames 301. A transmission rod 302 is movably installed in the inner cavity of the retaining frame 301. A winding wheel 303 is fixedly installed at one end of the transmission rod 302, and a cutting rope 304 for cutting stone is installed on the outside of the winding wheel 303. The cutting rope 304 is existing technology. The cutting rope 304 is shot peened. The shot peening treatment of the cutting rope 304 can effectively intervene in stress. Shot peening is also an existing technology. Several sets of intersecting limiting components 305 are provided on both sides of the outer side of the winding wheel 303. An output groove 306 is opened in the middle of the transmission rod 302. The inner cavity of the output groove 306 is installed with the outside of the control unit 6. The limiting component 305 includes a retaining hole 3051 formed on the surface of the winding wheel 303, and a limiting block 3052 is fixedly installed on the surface of the retaining hole 3051 by bolt threads. The control unit 6 includes a support frame 601 located at the front of the main body 1. A linear driver 602 is fixedly mounted on the top of the support frame 601. A cutting motor 603 is fixedly mounted on the output end of the linear driver 602. A drive block 604 inserted into the inner cavity of the output slot 306 is fixedly mounted on the output end of the cutting motor 603. Both the outer side of the drive block 604 and the inner cavity of the output slot 306 are rectangular. When the cutting unit 3 is cutting stone, the linear driver 602 on the control unit 6 is activated. The linear driver 602 drives the cutting motor 603 to move towards the inner cavity of the output slot 306 on the cutting unit 3. At this time, the cutting motor 603, driven by the linear driver 602, drives the drive block 604 to insert into the output slot 306, thus completing the connection between the control unit 6 and the cutting unit 3. Then, the cutting motor 603 is activated, and the cutting motor 603, through the cooperation of the drive block 604 and the output slot 306, drives the transmission rod 302 to rotate. The high-speed rotating transmission rod 302 drives the take-up wheel 303 to rotate at a high speed, which in turn drives the cutting rope 304 to rotate synchronously at high speed, thus cutting the stone. The cutting rope 304 cuts the stone, and the position of the cutting rope 304 is limited by the limiting components 305 on both sides. Therefore, the cutting rope 304 can only rotate at the same height in the same position. This will prevent uneven wear on the surface of the cutting rope 304 and ensure the regularity of the stone cutting gap. Since the several limiting components 305 are staggered, the contact area between the cutting rope 304 and the liquid is increased. When one limiting component 305 is damaged, only the corresponding limiting component 305 needs to be replaced. There is no need to replace the other limiting components 305. During the stone cutting process, the other cutting units 3 can also use the cutting rope 304 to support the stone cutting gap and prevent the stone from collapsing. The adjustment unit 4 includes a shaping frame 401 fixed on the outside of the main body 1. Several rotatable conveying gears 402 are movably mounted on the outside of the shaping frame 401. Tracks 403 are movably mounted on the outside of the several conveying gears 402. A transmission motor 404 is fixedly mounted on the outside of one of the conveying gears 402. The outside of the track 403 is fixed to the outside of several cutting units 3. After the stone cutting is completed, the control unit 6 is activated to disconnect the current cutting unit 3. Then, the transmission motor 404 on the adjustment unit 4 can be activated. The transmission motor 404 will drive one of the conveyor gears 402 to rotate. At this time, several conveyor gears 402 will work with the track 403 to move the cutting unit 3, which was originally in the cutting position, to a non-cutting position. Specifically, it will move towards the inside of the cleaning section 5. In this way, the subsequent cutting unit 3 will move to the position of the subsequent stone cutting. This way, after each stone cutting is completed, a new cutting unit 3 can be replaced. This will prevent the long-term use of a single cutting unit 3, which would cause the cutting rope 304 on the cutting unit 3 to have a short service life. The cleaning unit 5 includes a water tank 501 located at the bottom of the main body 1. The bottom of the adjustment unit 4 and several cutting units 3 are located inside the water tank 501. A water guide pipe 502 is fixedly installed on the outside of the water tank 501. A water pump 503 is fixedly installed at one end of the water guide pipe 502. A transmission pipe 504 is fixedly installed at the output end of the water pump 503. An atomizing nozzle 505 is fixedly installed at one end of the transmission pipe 504. A diversion pipe 506 is fixedly installed at one end of the transmission pipe 504. Liquid spray nozzles 507 are provided on the diversion pipe 506. Each spray nozzle 507 faces the cutting unit 3. A recycling tank 508 is opened on the surface of the water tank 501. A filter frame 509 is movably installed in the inner cavity of the recycling tank 508. A sewage circulation component 8 is provided on the outside of the water tank 501. When the equipment is cutting stone, the water pump 503 can be started. The water pump 503 will transfer the liquid inside the water tank 501 through the water pipe 502. The transferred liquid will be atomized on the outside of the stone through the atomizing nozzle 505 at one end of the transmission pipe 504. At this time, the atomized liquid can be used to suppress dust and other impurities generated during the cutting of the stone, and prevent dust from spreading. At the same time, the diversion pipe 506 will flush the top of the cutting rope 304 on the cutting unit 3 with liquid through the spray nozzle 507. The flushing position is horizontal and parallel to the gap of the stone being cut. In this way, while cooling and descaling the cutting rope 304, the liquid can also be used to flush the gap of the stone. The circulation component 8 includes a circulation pump 801 fixed to the outside of the water storage tank 501. A circulation pipe 802 is fixedly installed at both ends of the circulation pump 801. One end of one circulation pipe 802 extends to the top of the filter screen frame 509 on the water storage tank 501, and the opening of the other circulation pipe 802 is located at the bottom of the filter screen frame 509. Several sets of rotatable transmission rods 803 are fixedly installed in the inner cavity of the water storage tank 501. A scraper wheel 804 is fixedly installed on the outside of each transmission rod 803. A conveyor wheel 805 is also installed at one end of each transmission rod 803. A transmission belt 806 is installed on the outside of several conveyor wheels 805. A transmission gear 807 is also installed on one of the transmission rods 803. The transmission gear 807 is matched and driven by the outside of the adjustment unit 4. A drain valve 808 is provided at the bottom of the water storage tank 501. When the equipment of this application is running, the circulation pump 801 can be started simultaneously. The circulation pump 801 will circulate the liquid between the upper and lower positions of the filter frame 509 inside the water storage tank 501 through two circulation pipes 802. This ensures that the liquid is always in a flowing state. At this time, the flowing liquid can flush and cool the cutting unit 3 and the regulating unit 4, and impurities will be carried into the bottom of the filter frame 509 on the water storage tank 501. At the same time, the filter frame 509 will block the impurities and prevent them from re-entering the top of the filter frame 509. This ensures the cleanliness of the liquid at the top of the filter frame 509 inside the water storage tank 501. The track 403 has several toothed grooves 9 on its surface. A drive gear 11 meshes with the surface of the toothed grooves 9. When the track 403 is running, the toothed grooves 9 will drive the drive gear 11 to rotate, and the drive gear 11 will drive the transmission gear 807 to rotate. When the adjustment unit 4 is in operation, the surface track 403 drives the transmission gear 807 to rotate through the power gear 11 on the tooth groove 9. At this time, the transmission gear 807 drives the current transmission rod 803 to rotate synchronously. This works in conjunction with the rotating conveyor wheel 805 to drive all the transmission rods 803 to rotate through the transmission belt 806. In this way, all the transmission rods 803 can drive the conveyor wheel 805 to rotate, thereby scraping off impurities from the surface of the filter screen frame 509. At the same time, with the agitation of the water flow, impurities are not easy to settle to the bottom. This allows the circulating pump 801 to remove impurities, improving the cleanliness of the liquid on the filter screen frame 509. Several sets of descaling components 10 are fixedly installed on the steel wire rope of the cutting rope 304. The descaling components 10 are used to remove dirt from the cutting gaps on the stone and prevent dirt residue from remaining inside the stone gaps. The descaling component 10 includes a shaping tube 1001 fixed on the cutting rope 304, and several curved plates 1002 are fixedly installed on the outside of the shaping tube 1001. When the cutting rope 304 rotates at high speed, the dirt inside the stone gaps can be scraped off through the curved plate 1002 outside the shaping tube 1001.

[0024] The operating method of stone bridge cutting equipment with stress intervention function includes: Step 1: Check the stability of each component connection and prepare for operation. Inject sufficient cooling liquid into the cleaning section 5. First, conduct a comprehensive check on the connection stability of each component, focusing on confirming the fixation of the main body 1 to the ground, the lubrication of the guide rail of the conveying section 2, and the firmness of the fixing frame 301 of the cutting unit 3. Check whether the stroke of the linear drive 602 of the control unit 6 is normal and ensure that the drive block 604 can be smoothly inserted into the output slot 306. Inject sufficient cooling liquid (usually water or coolant containing rust inhibitor) into the water tank 501 of the cleaning section 5. The liquid level should submerge the filter frame 509, the bottom of the adjustment unit 4, and several cutting units 3 at the bottom. Ensure that the water pump 503 suction port is not blocked. Start the circulation component 8 under no-load and observe whether the transmission rod 803 drives the scraper wheel 804 to rotate smoothly. Confirm that the filter frame 509 is not stuck. Test the water output status of the atomizing nozzle 505 and the spray port 507 to ensure that there is no blockage and that the spray angle is accurately directed towards the cutting and cleaning positions. Step Two: Place the stone to be processed on the conveyor unit 2. The conveyor unit 2 moves the stone to the cutting position of the cutting unit 3. Using external hoisting equipment, the stone is placed stably on the support plate of the conveyor unit 2. Start the clamping assembly 205. The push rod motor pushes the clamping plates on both sides towards the center. The rubber protective layer and anti-slip points on the surface of the clamping plates provide a flexible yet stable clamping of the stone. During the clamping process, the rubber layer absorbs the micro-vibrations caused by the weight of the stone, avoiding hard contact that could cause the stone edges to crack. After confirming that the stone is centered, lock the clamping state to prevent the cutting path from deviating due to shaking during the cutting process and to ensure cutting accuracy. Start the drive assembly 202 (lead screw adjustment mechanism). The drive motor drives the lead screw to rotate, causing the support base 203 and the stone to move horizontally to the preset cutting starting position. Step 3: Start the control unit 6. The control unit 6 drives a group of cutting units 3 to cut the stone conveyed on the conveying unit 2. The other cutting units 3, which are at the same horizontal position as the cutting unit 3 responsible for cutting the stone, support the gap in the stone cutting. Specifically, the linear driver 602 pushes the cutting motor 603 forward, so that the drive block 604 is precisely inserted into the output slot 306 of the current working cutting unit 3, completing the power coupling. Start the cutting motor 603, drive the transmission rod 302 to rotate at high speed, and then drive the shot-peened cutting rope 304 to rotate at high speed. The shot-peened cutting rope 304 has a stress intervention function, which can effectively release the internal stress generated by cutting and reduce the expansion of stone cracks. When the current cutting unit 3 is performing the main cutting operation, the other non-working cutting units 3 at the same horizontal position remain stationary or in a low-speed follow-up state. Their cutting ropes 304 penetrate into the formed cutting gap, providing physical support for the stone gap, effectively preventing the gap from collapsing or closing due to the stone's own weight or cutting stress, and ensuring the verticality and regularity of the cut surface. Step 4: During the stone cutting process, the cleaning unit 5 is activated simultaneously. The cleaning unit 5 sprays liquid atomized onto the top of the stone being cut, and also washes the surface of the cutting unit 3 and the corresponding stone cutting seams. Simultaneously, the water pump 503 of the cleaning unit 5 is activated, and liquid is sprayed from the atomizing nozzle 505 through the transmission pipe 504, forming a fine mist that covers the top of the stone cutting, instantly absorbing and settling the dust generated during cutting, preventing dust from polluting the environment. The diversion pipe 506 sprays high-pressure liquid streams through the spray nozzle 507 onto the top of the cutting rope 304 and the stone cutting seams, with the liquid stream direction parallel to the horizontal direction of the cutting seams. Not only does it cool down the high-speed rotating cutting rope 304 to prevent overheating and annealing, but it also uses fluid kinetic energy to flush away stone powder and debris in the gaps, keeping the cutting channel unobstructed. The descaling component 10 (curved plate 1002) on the cutting rope 304 rotates at high speed with the rope, actively scraping away stubborn dirt adhering to the inner wall of the stone gaps, and carrying it out with the water flow. Unlike traditional straight plates, the curved plate 1002 can better fit the irregular inner wall of the cutting gaps and generate micro-vortices when rotating at high speed, 'rolling' stone powder out of the gaps in dead corners. Combined with the water flow, it achieves cleaning without dead corners and prevents the cutting rope 304 from swaying due to dust accumulation. Step 5: After the stone cutting is completed, the control unit 6 is activated to disconnect the current cutting unit 3. After a single stone cutting is completed, the cutting motor 603 is stopped first, and then the linear driver 602 of the control unit 6 is activated to move in the reverse direction, driving the drive block 604 to exit from the output slot 306, disconnecting the power connection of the current cutting unit 3, and preparing for the subsequent position rotation. Step Six: Start the adjustment unit 4. The adjustment unit 4 moves the cutting unit 3, which is in the cutting position, toward the water tank 501 on the cleaning section 5. Then, the liquid inside the water tank 501 is used to soak, cool, and clean the cutting unit 3. Then, the control unit 6 is restarted to connect and drive the replaced cutting unit 3. The transmission motor 404 of the adjustment unit 4 is started, which drives the conveyor gear 402 to rotate and drives the track 403 to move. The cutting unit 3, which has just completed high-intensity cutting and is in a high-temperature state, is moved out of the cutting unit and transported to the water tank 501 of the cleaning section 5. At the same time, the new cutting unit 3, which was originally in the water tank 501 and has been cleaned and cooled, is moved to the cutting position. The control unit 6 is restarted to connect the newly positioned cutting unit 3. This rotation mechanism avoids the continuous operation of a single cutting unit 3 for a long time and significantly extends the service life of the cutting rope 304. Step 7: When the adjustment unit 4 is running, it drives a portion of the circulation component 8. Simultaneously, the circulation pump 801 on the circulation component 8 is started, allowing liquid exchange between the upper and lower positions of the filter frame 509 inside the cleaning section 5. Liquid containing impurities is transferred to the bottom cavity of the filter frame 509 in the water tank 501, while clean liquid remains at the top of the filter frame 509. When the cutting unit 3 is immersed in the top of the filter frame 509 inside the water tank 501, it is repeatedly flushed by the flowing clean liquid and is not contaminated by residual dirt. When the adjustment unit 4 is running (track 403 moves), the toothed grooves 9 on the surface of the track 403 mesh with the drive gear 11 to achieve transmission gear 80. 7. Rotation drives the transmission rod 803, conveyor wheel 805 and conveyor belt 806 to work together, so that the scraper wheel 804 scrapes the surface of the filter screen frame 509. Simultaneously, the circulation pump 801 is started, and the liquid with more impurities at the bottom of the water tank 501 is drawn to the top of the filter screen frame 509 through the circulation pipe 802, or the liquid is forced through the filter screen by pressure difference. The stone chips and dirt in the flowing liquid are blocked by the filter screen frame 509 and settle to the bottom, while the clean liquid is retained at the top of the filter screen frame 509. The high-temperature cutting unit 3 that just entered the water tank 501 is immersed in the clean liquid flowing at the top, achieving rapid cooling and deep cleaning, avoiding secondary pollution. The rotation of the scraper wheel 804 further prevents impurities from caking on the surface of the filter screen and improves filtration efficiency. Step 8: When the cutting unit 3 is cutting the stone, the descaling component 10 is also carried into the cutting gap of the stone by the cutting rope 304 to scrape off impurities. The scraped impurities are flushed and cleaned by the flowing liquid inside the water tank 501. This allows for repeated cleaning of impurities in the stone gaps. When the new cutting unit 3 performs the next round of stone cutting, the descaling component 10 it carries enters the cutting gap again and uses the geometry of the curved plate 1002 to scrape off residual dirt. The scraped impurities are immediately flushed away by the flowing liquid provided by the water tank 501 and enter the circulation filtration system. This process forms a closed loop of "cutting-scraping-flushing-filtration" to ensure the cleanliness of the stone gaps during continuous operation and improve the quality of the cut surface. Step 9: Equipment cleaning and maintenance. Clean the stone chips on the cutting unit 3, check the wear of the cutting rope 304, and replace it if the wear is severe. Clean the stone chips remaining on the filter screen frame 509, open the drain valve 808 at the bottom of the water tank 501 to drain the sedimented impurities, and replenish the liquid in the water tank 501. After all the work is completed, manually or automatically clean the stone chips attached to the surface of the cutting unit 3.
