[0038] It can be understood that the roll grinder support 5 is provided with the polishing device 2 along the length direction, and the moving device 3 is fixedly connected with the polishing device 2 through the hole in the middle of the support, which ensures the stability and accuracy of the polishing device 2 during transverse displacement, thereby ensuring the stability of the grinding quality.

The high-pressure water outlet device 610 is located at the top of the polishing device 2, and the high position enables the cooling liquid to uniformly cover the entire grinding area, thereby fully playing its lubricating and cooling role. The water inlet 620 located at the bottom of the polishing device 2 is responsible for collecting the used cooling liquid, which ensures the rapid recovery of the cooling liquid and reduces the waste of the cooling liquid. The flushing unit 6 not only prolongs the service life of the polishing device 2, but also improves the stability and consistency of the grinding process. The circulating unit 7 realizes the efficient recycling of the cooling liquid through the cooperation of the collection and filtration device 710 and the circulating pipeline 720. The collection and filtration device 710 is located below the polishing device 2, which ensures that the sand particles and impurities generated during the grinding process can be collected in time to prevent them from entering the cooling liquid circulating pipeline 720.

[0039] In some embodiments of the present application, referring to Figure 3 As shown in the figure, the high-pressure water outlet device 610 comprises a spray head 6101, a nozzle 6102 and a base 6103, one end of the spray head 6101 is inserted into one end of the base 6103, the other end of the spray head 6101 is provided with a flow hole, the nozzle 6102 is arranged in the spray head 6101, and the end face of one end of the nozzle 6102 is connected with the hole wall of the flow hole in a clamping manner, and one end of the nozzle 6102 communicates with the flow hole.

[0040] In some embodiments of the present application, the high-pressure water outlet device 610 further comprises a stepped pressure booster 6104 and a filter pressure head 6105, one end of the filter pressure head 6105 is inserted into the other end of the base 6103, one end of the filter pressure head 6105 communicates with one end of the stepped pressure booster 6104, the stepped pressure booster 6104 is arranged in the spray head 6101, and the other end of the stepped pressure booster 6104 communicates with the other end of the nozzle 6102.

[0041] Specifically, when connected with the pipeline, the circulating pipeline 720 is connected with the filter pressure head 6105, and the water with a certain pressure flows into the filter pressure head 6105 from the circulating pipeline 720, and is filtered through the filter hole. Since the inside of the filter pressure head 6105 is arranged in a conical shape, it can also play a role in preliminary pressure boosting for the water. When the water passes through the stepped pressure booster 6104, it enters the channel with a small aperture from the channel with a large aperture, and the water realizes the second pressure boosting. When the water passes through the connection between the nozzle 6102 and the stepped pressure booster 6104, it realizes the third pressure boosting through the formed vortex area, and finally sprays out from the water outlet.

[0042] It can be understood that the combination of the spray head 6101, the nozzle 6102 and the base 6103 not only simplifies the assembly and maintenance of the device, but also ensures the close connection between the components, thereby improving the sealing and stability of the device. One end of the spray head 6101 is inserted into the base 6103, and the other end is provided with a flow hole, so that the cooling liquid can flow smoothly into the nozzle 6102, reducing the flow resistance and improving the spraying efficiency of the cooling liquid. The nozzle 6102 is arranged in the spray head 6101 and is connected with the hole wall of the flow hole through the end face, which not only ensures the fixed position of the nozzle 6102, but also prevents the leakage of the cooling liquid during spraying, thereby improving the reliability of the device. Secondly, one end of the filter booster head 6105 is inserted into the other end of the base 6103 and communicates with one end of the stepped booster 6104, realizing the preliminary filtration and boosting of the cooling liquid. The conical shape inside the filter booster head 6105 not only improves the flow efficiency of the cooling liquid, but also preliminarily filters the cooling liquid through the filter hole, removing large particles in the cooling liquid, thereby preventing the nozzle 6102 from being blocked. The stepped booster 6104 is arranged in the spray head 6101 and realizes the secondary boosting of the cooling liquid through the channels with different hole diameters from large to small. The stepped boosting not only improves the spraying pressure of the cooling liquid, but also ensures the stability of the pressure, thereby improving the consistency of the cooling effect. During the spraying process of the cooling liquid, the high-pressure water outlet device 610 further improves the spraying efficiency of the cooling liquid through multi-stage boosting and the formation of the vortex area. When the cooling liquid with a certain pressure flows into the filter booster head 6105 from the circulating pipeline 720, it is first preliminarily filtered through the filter hole, and then the cooling liquid enters the stepped booster 6104, from the channel with large hole diameter to the channel with small hole diameter, realizing the secondary boosting. Finally, when the cooling liquid passes through the connection between the nozzle 6102 and the stepped booster 6104, it is subjected to three times of boosting in the formed vortex area, thereby further improving the spraying pressure of the cooling liquid. Multi-stage boosting not only ensures the efficient spraying of the cooling liquid, but also improves the pressure stability of the cooling liquid, thereby providing more reliable cooling support for the grinding process.

[0043] In some embodiments of the present application, referring to Figure 4 As shown in the figure, the collecting filter device 710 includes a recovery tank 7101, a circulating pump 7102, a filter net 7103 and a liquid inlet pipe 7104, the circulating pump 7102 is arranged in the recovery tank 7101, the liquid inlet of the circulating pump 7102 communicates with the liquid inlet pipe 7104, the liquid outlet of the circulating pump 7102 communicates with the circulating pipeline 720, the filter net 7103 is fixedly connected inside the recovery tank 7101, and the liquid inlet pipe 7104 extends through the filter net 7103 to the bottom of the filter net 7103.

[0044] Specifically, the recovery tank 7101 is used to collect the flowing cooling liquid, and the filter screen 7103 is arranged in the recovery tank 7101 to retain solid particles and prevent them from sinking to the bottom of the recovery tank 7101. The inlet of the liquid inlet pipe 7104 is located at the bottom of the recovery tank 7101 to absorb the filtered cooling liquid, and the absorption of the cooling liquid is realized through the circulating pump 7102.

[0045] It can be understood that the recovery tank 7101 serves as a collection container for the cooling liquid, and the filter screen 7103 is fixedly connected inside the recovery tank 7101, which not only simplifies the assembly and maintenance of the device, but also ensures efficient filtration of the cooling liquid during the recovery process. The presence of the filter screen 7103 can intercept solid particles in the cooling liquid and prevent them from sinking to the bottom of the recovery tank 7101, thereby avoiding the blockage of the circulating pump 7102 and the pipeline by solid particles and prolonging the service life of the equipment. The liquid inlet pipe 7104 penetrates the filter screen 7103 and extends to the bottom of the filter screen 7103, so that the cooling liquid can be filtered by the filter screen 7103 during the recovery process, thereby ensuring the cleanliness of the cooling liquid sucked by the circulating pump 7102 and improving the stability of the cooling liquid circulation. Secondly, the liquid inlet of the circulating pump 7102 communicates with the liquid inlet pipe 7104, and the liquid outlet communicates with the circulating pipeline 720, realizing the recovery and stable circulation of the cooling liquid. The circulating pump 7102 can suck the filtered cooling liquid from the bottom of the recovery tank 7101 through its strong suction force, and deliver it to the high-pressure water outlet device 610 through the circulating pipeline 720, thereby realizing the recycling use of the cooling liquid. Not only the recovery efficiency of the cooling liquid is improved, but also the stable flow of the cooling liquid during the circulation process is ensured, thereby providing more reliable cooling support for the grinding process.

[0046] In some embodiments of the present application, referring to Figure 5 As shown in the figure, the circulating pipeline 720 is further provided with a spiral flow guide device 9, the spiral flow guide device 9 comprises a first rotating shaft 910, a spiral blade 920, a motor 930, a flow guide pipe 940 and a water collecting box 950, the upper portion of the high-pressure water outlet device 610 is communicated with the water collecting box 950, the upper portion of the water collecting box 950 is communicated with the flow guide pipe 940, and the middle portion of the water collecting box 950 is communicated with the circulating pipeline 720, the first rotating shaft 910 is located in the flow guide pipe 940, the spiral blade 920 is fixedly installed on the first rotating shaft 910, the first rotating shaft 910 is fixedly installed on the output end of the motor 930, and the first rotating shaft 910 penetrates the flow guide pipe 940 into the water collecting box 950.

[0047] Specifically, the upper part of the high-pressure water outlet device 610 is provided with a water collecting box 950, the upper part of the water collecting box 950 is connected with the spiral flow guide device 940, the side of the water collecting box 950 is connected with the circulating pipeline 720, the first rotating shaft 910 penetrates the flow guide pipe 940 to the water collecting box 950, and the spiral blade 920 is driven to rotate by rotating, so that the cooling liquid is preliminarily guided and the flow rate is improved.

[0048] It can be understood that the water collecting box 950 serves as a collection and transition container for the cooling liquid, the upper part of the water collecting box 950 is connected with the flow guide pipe 940, and the middle part of the water collecting box 950 is connected with the circulating pipeline 720, so that the assembly and maintenance of the device are simplified, and the efficient flow guide of the cooling liquid during the flow process is ensured. The first rotating shaft 910 and the spiral blade 920 are arranged in the flow guide pipe 940, so that the cooling liquid can be pushed by the spiral blade 920 during the flow process, thereby improving the flow rate of the cooling liquid. The first rotating shaft 910 is fixedly installed on the output end of the motor 930 and penetrates the flow guide pipe 940 to the water collecting box 950, so that the spiral blade 920 can rotate at high speed through the driving of the motor 930, thereby preliminarily guiding the cooling liquid and improving the flow efficiency of the cooling liquid. The spiral blade 920 is fixedly installed on the first rotating shaft 910 and rotates at high speed through the driving of the motor 930, so that the cooling liquid can be pushed by the spiral blade 920 during the flow process, thereby improving the flow rate of the cooling liquid. The rotation of the spiral blade 920 not only increases the flow power of the cooling liquid, but also causes the cooling liquid to form an eddy current during the flow process, thereby further improving the flow efficiency of the cooling liquid. The efficient flow guide not only ensures the stable flow of the cooling liquid in the circulating pipeline 720, but also improves the spraying effect of the cooling liquid in the high-pressure water outlet device 610, thereby providing more reliable cooling support for the grinding process.

[0049] In some embodiments of the present application, referring to Figures 6-7 As shown in the figure, the filter unit 8 includes a filter screen 810, a filter shell 820, a groove 830, a discharge port 840, a filter device, and a flow monitoring device 880. The filter screen 810 is arranged in the circulating pipeline 720. The filter shell 820 is installed on one side of the circulating pipeline 720. The groove 830 is arranged on the side wall of the filter shell 820 connected with the circulating pipeline 720. The groove 830 is arranged obliquely. The discharge port 840 is arranged at the lower part of the filter shell 820 and is connected with the lower oblique end of the groove 830. The filter device is arranged in the filter shell 820. The flow monitoring device 880 is arranged on one side of the filter shell 820.

[0050] In some embodiments of the present application, the filtering device comprises a telescopic cylinder 850, a push plate 860 and a wedge block 870, the telescopic cylinder 850 is installed on the side of the filtering shell 820 away from the circulating pipeline 720, the output end of the telescopic cylinder 850 is fixedly connected with the push plate 860, the push plate 860 is an arc-shaped plate, and the push plate 860 matches the cross-sectional structure of the groove 830, the wedge block 870 is fixedly connected to the upper inner wall of the filtering shell 820, and the wedge block 870 is provided with a plurality of.

[0051] In some embodiments of the present application, the filtering net 810 is an elastic net, and the push plate 860 is an elastic plate.

[0052] Specifically, since the inhaled cooling water contains impurities, after long-term use, the impurities will block in the circulating pipeline 720, thereby affecting the heat dissipation efficiency. In the present embodiment, the filtering net 810 is arranged in the circulating pipeline 720 to block the inflow of impurities. However, although the filtering net 810 can prevent the inflow of impurities to a certain extent, the impurities will block at the front end of the filtering net, thereby still affecting the heat dissipation efficiency. Therefore, by arranging the inclined groove 830 at the front end of the filtering net 810, the impurities in front of the filtering net 810 can flow into the groove 830 and then flow out through the discharge port 840. The push plate 860 is driven by the telescopic cylinder 850 to move, thereby pushing the filtering net 810. Since the impurities will stay on the holes of the filtering net 810, thereby blocking the filter holes of the filtering net 810, the wedge block 870 collides with the top of the push plate 860. By touching the wedge block 870 during the movement of the push plate 860, the filtering net 810 and the push plate 860 are vibrated, thereby shaking off the impurities to a certain extent. Then, the telescopic cylinder 850 is retracted to connect the groove 830 and the discharge port 840, thereby making the impurities flow out of the circulating pipeline 720.

[0053] It can be understood that the setting of the filter screen 810 can block impurities in the cooling water from entering and prevent the impurities from affecting the heat dissipation performance of the circulating pipeline 720, ensuring the cleanliness of the cooling water and the heat dissipation efficiency. The inclined groove 830 of the filter shell 820 is designed so that the impurities blocked by the filter screen 810 can smoothly slide into the groove 830 and be discharged through the discharge port 840, avoiding the problem of blockage caused by the accumulation of impurities in front of the filter screen 810, and further improving the operation stability. Secondly, the filter device realizes the automatic cleaning function of the filter screen 810 through the cooperation of the telescopic air cylinder 850, the push plate 860 and the wedge block 870. The telescopic air cylinder 850 drives the push plate 860 to move, and the push plate 860 collides with the wedge block 870 during movement, generating vibration, which can shake off the impurities attached to the filter screen 810, ensuring the smoothness of the filter screen 810. Not only reduces the frequency and cost of manual cleaning, but also improves the degree of automation and operation efficiency. In addition, the elastic design of the push plate 860 and the filter screen 810 can absorb vibration energy during cleaning, reduce the impact on the equipment, and prolong the service life of the equipment. The setting of the flow monitoring device 880 can monitor the flow change of the cooling water in real time, timely discover and warn the blockage or abnormal condition of the filter screen 810, and improve the intelligent level and maintenance convenience of the equipment.
