[0024] As Figures 1 - 10 shown, a roll cleaning device provided by an embodiment of the present invention includes: a frame 1, a flexible airbag 2, a grinding fluid adding device 3, and a controller.

[0025] Among them, the frame 1 is used to be placed on one side opposite to the roll surface; the flexible airbag 2 is arranged on the side of the frame 1 close to the roll surface, and a wiping consumable is covered on the side of the flexible airbag 2 facing the roll. The flexible airbag 2 is communicated with an external air source through a pressure regulating valve 21. The flexible airbag 2 is used to press the wiping consumable tightly against the roll surface side; the grinding fluid adding device 3 is arranged on the frame 1. The grinding fluid adding device 3 has a detection mechanism 31. The grinding fluid adding device 3 is used to add grinding fluid to the gap between the wiping consumable and the roll surface. The detection mechanism 31 is used to detect the residue information on the roll surface; the controller is connected to the grinding fluid adding device 3 and the pressure regulating valve 21 for control. The controller is used to control the grinding fluid adding device 3 to add grinding fluid according to the residue information and control the opening of the pressure regulating valve 21 to adjust the grinding pressure exerted by the flexible airbag 2 between the wiping consumable and the roll surface.

[0026] During specific implementation, as Figure 1As shown, the operator places the frame 1 on one side opposite to the roll surface. After adjusting the opening degree of the pressure regulating valve 21 through the controller to complete the adjustment of the grinding pressure applied by the flexible airbag 2 between the wiping consumable and the roll surface, the grinding fluid adding device 3 is then controlled to add grinding fluid into the gap between the wiping consumable and the roll surface according to the residue information transmitted by the detection mechanism 31. Compared with the traditional method of manually cleaning the roll surface with a wiping consumable, in this application, through the flexible airbag 2 and the regulating valve, flexible contact between the wiping consumable and the roll surface is achieved to ensure accurate adjustment of the grinding pressure on the roll and reduce grinding damage to the roll surface.

[0027] It should be noted that the detection mechanism 31 can adopt a spectrometer. The spectrometer emits light of a specific wavelength through a light source and irradiates it onto the roll. The surface metal foreign matters or residues on the roll will absorb or reflect the light source. The light signal captured by the spectrometer is converted into spectral data. By analyzing the characteristic peaks on the spectrogram, the types of metal elements or compounds existing on the roll are determined, quantitative analysis of the surface metal foreign matters or residues is carried out, whether the content of metal foreign matters or residues on the roll surface reaches an acceptable threshold is evaluated, and the detection information is fed back to the controller to achieve accurate detection. Of course, the detection mechanism 31 can also adopt other structures with residue detection functions. Through real-time monitoring and adjustment, the stability of the grinding fluid addition and the grinding effect of the roll cleaning equipment are improved.

[0028] Specifically, in this embodiment, the grinding fluid adding device 3 includes: a liquid material tank 32, a metering pump 33, a nozzle pipe 34, and a driving mechanism 35. The liquid material tank 32 is arranged on the frame 1 and is used for storing the grinding fluid; the metering pump 33 is communicated with the liquid material tank 32 and is used for adjusting the flow rate of the conveyed grinding fluid; one end of the nozzle pipe 34 is rotatably communicated with the metering pump 33 through a flexible pipe, and the other end of the nozzle pipe 34 is used for adding the grinding fluid; the driving end of the driving mechanism 35 is drivingly connected with the nozzle pipe 34, and the driving mechanism 35 is used for driving and adjusting the inclination angle of the nozzle pipe 34.

[0029] As Figure 2As shown in the figure, during operation, the grinding fluid is stored in the liquid material tank 32. When it is necessary to add the grinding fluid, the controller controls the metering pump 33 to adjust the flow rate of the grinding fluid delivered to the nozzle pipe 34, and then starts the driving mechanism 35 to enable the nozzle pipe 34 to adjust the tilting angle through the flexible pipe, so as to ensure that the nozzle pipe 34 can smoothly deliver the grinding fluid to the gap between the wiping consumable and the roll surface, improving the working efficiency of adding the grinding fluid to the roll cleaning device. Compared with the traditional manual addition of the grinding fluid, this application can, through the controller and the detection mechanism 31, realize the addition of the grinding fluid at the corresponding position of the roll, avoiding the waste of the grinding fluid. Among them, the flexible pipe can adopt a rubber pipe or a pipe made of other flexible materials, as long as it ensures that the metering pump 33 and the nozzle pipe 34 are connected and a rotational connection can be achieved between the metering pump 33 and the nozzle pipe 34, improving the flexibility of use of the grinding fluid addition device 3. Exemplarily, the driving mechanism can be a motor or other structure capable of driving the nozzle pipe 34 to rotate.

[0030] As Figure 1 and Figure 2 shown, specifically, in this embodiment, a plurality of grinding fluid addition devices 3 are provided, and the plurality of grinding fluid addition devices 3 are arranged in sequence along a direction parallel to the width direction of the roll surface, and adjacent two grinding fluid addition devices 3 are connected by a partition 36. According to rolls of different widths, the operator can, on the basis of the already fixed grinding fluid addition device 3, add a plurality of grinding fluid addition devices 3 in multiple times to make the grinding fluid addition width of the plurality of grinding fluid addition devices 3 consistent with the width of the roll surface, ensuring that the grinding fluid can flow into the entire width of the roll surface of the roll. Among them, each grinding fluid addition device 3 is correspondingly equipped with a detection mechanism 31. By feeding back the residue information of each detection mechanism 31 to the controller, the addition or reduction of the corresponding number of grinding fluid addition devices 3 can be realized according to the residue information, that is, the operator can correspondingly adjust the grinding fluid addition width composed of a plurality of grinding fluid addition devices 3 according to rolls of different widths. At the same time, the grinding fluid addition device 3 only adds the grinding fluid to the part where the detection mechanism 31 detects the residue of metal foreign objects, reducing the waste of the grinding fluid and avoiding the risk of surface damage caused by repeatedly grinding the polished part of the roll surface of the roll.

[0031] As Figure 3As shown in the figure, specifically, in this embodiment, the roll cleaning device further includes a grinding fluid recovery device 4. The grinding fluid recovery device 4 includes a recovery tank 41, a recovery nozzle 42, and a diaphragm pump 43. The recovery tank 41 is arranged on the frame 1 and is located below the flexible airbag 2. The recovery tank 41 is used to recover the grinding fluid flowing out from the gap between the wiping consumables and the roll surface. One end of the recovery nozzle 42 extends into the recovery tank 41. One end of the diaphragm pump 43 is communicated with the other end of the recovery nozzle 42, and the other end of the diaphragm pump 43 is communicated with the liquid material tank 32. During operation, the grinding fluid flows out from the gap between the wiping consumables and the roll surface. The recovery tank 41 is located below the flexible airbag 2, so that the grinding fluid can flow out and be recovered and temporarily stored in the recovery tank 41, and then the grinding fluid is transported from the recovery tank 41 to the liquid material tank 32 through the recovery nozzle 42 and the diaphragm pump 43, realizing the secondary recycling of the grinding fluid and avoiding the waste of the grinding fluid. Among them, the recovery nozzle 42 can also be arranged near the roll surface below the flexible airbag 2 to ensure the full recovery of the residual grinding fluid.

[0032] As Figure 1 and Figure 4 shown in the figure, specifically, in this embodiment, a scraper 44 is arranged at the front edge of the recovery tank 41 close to the roll surface. The scraper 44 is used to scrape and collect the residual grinding fluid on the roll surface. The front edge position of the scraper 44 fits the roll surface. When the roll rotates for grinding and cleaning, the scraper 44 can fully scrape the residual grinding fluid on the roll surface and collect the grinding fluid into the recovery tank 41, avoiding the waste of the grinding fluid and reducing the residual grinding fluid on the roll surface.

[0033] Specifically, in this embodiment, the frame 1 includes a base 11, a first column 12, a second column 13, and a locking mechanism. The first column 12 is slidably connected to the base 11. The second column 13 is arranged parallel to the first column 12 and is slidably connected to the base 11. The locking mechanism 14 connects the first column 12 and the second column 13, and the locking mechanism 14 is used to lock the positions of the first column 12 and the second column 13.

[0034] As Figure 1 and Figure 5 shown in the figure, during operation, the operator can adjust according to the grinding fluid addition width formed by the arrangement of multiple grinding fluid addition devices 3, so that the first column 12 and the second column 13 slide close to or away from each other to adapt to rolls of different widths. After adjusting to the appropriate position, the positions of the first column 12 and the second column 13 are fixed and locked through the locking mechanism 14, completing the adjustment of the frame 1 and improving the use flexibility of the roll cleaning device.

[0035] In some other embodiments, both the first upright post 12 and the second upright post 13 are telescopic upright posts. When the position heights of the grinding fluid adding devices 3 provided on the first upright post 12 and the second upright post 13 cannot meet the requirement for adding grinding fluid, the telescopic upright posts can be adjusted to realize the adjustment of the position heights of the grinding fluid adding devices 3 provided on the frame body 1, so as to ensure the smooth addition of the grinding fluid; or when the installation positions of the flexible air bags 2 provided on the first upright post 12 and the second upright post 13 cannot be in full contact with the roll surface, the telescopic upright posts can be adjusted to realize the adjustment of the position heights of the flexible air bags 2 provided on the frame body 1, so as to ensure the full contact between the flexible air bags 2 and the roll surface.

[0036] As Figure 4 shown, specifically, in this embodiment, the locking mechanism 14 includes: a first connecting member 141, a second connecting member 142 and a spring pin 143. The first connecting member 141 is fixedly connected to the first upright post 12; the second connecting member 142 is fixedly connected to the second upright post 13, and the second connecting member 142 is provided with a plurality of pin holes 144 which are arranged at intervals in a direction parallel to the width direction of the roll surface; the first connecting member 141 is provided with a spring pin 143, and the spring pin 143 and the pin holes 144 are cooperatively connected to adjust the width of the frame body 1 in the width direction parallel to the roll surface, so as to install the corresponding number of grinding fluid adding devices 3.

[0037] During operation, through the cooperation of the spring pin 143 on the first connecting member 141 and the pin holes 144 on the second connecting member 142, the set number of the grinding fluid adding devices 3 can be increased or decreased as required according to the width of the roll surface of the roll, realizing the adjustment of the width of the frame body 1 in the width direction parallel to the roll surface, which is convenient for operation. Of course, the locking mechanism 14 can also adopt ways such as threaded connection, welding or clamping to fix the relative positions between the first upright post 12 and the second upright post 13.

[0038] As Figure 1 and Figure 4 shown, specifically, in this embodiment, the frame body 1 is further provided with a fixing device 5. The fixing device 5 includes: a first support block 51, a second support block 52 and two groups of pressing mechanisms 53. The first support block 51 is fixedly connected to the first upright post 12; the second support block 52 is fixedly connected to the second upright post 13. The first support block 51 and the second support block 52 are arranged oppositely, and a receiving cavity is formed by the sides of the first support block 51 and the second support block 52 close to the roll surface. A part of the flexible air bag 2 is accommodated in the receiving cavity, and the wiping consumable covers the surface of the first support block 51, the flexible air bag 2 and the surface of the second support block 52; the two groups of pressing mechanisms 53 are used to press the wiping consumable against the first support block 51 and the second support block 52.

[0039] During operation, on the side of the first support block 51 and the second support block 52 close to the roll surface, an accommodation cavity is formed. The internal volume of the accommodation cavity can be adjusted accordingly as the first column 12 and the second column 13 slide, so that the flexible airbag 2 can partially fill the accommodation cavity. The part of the flexible airbag 2 exposed outside the accommodation cavity can make flexible contact with the wiping consumable and apply an appropriate grinding pressure to ensure the grinding gap between the wiping consumable and the roll surface. After adjusting the relative positions of the first support block 51 and the second support block 52, the wiping consumable is fixed to the first support block 51 and the second support block 52 through the pressing mechanism 53, realizing the fixation of the wiping consumable to adapt to wiping consumables of different lengths and facilitating the fixation and disassembly of the wiping consumable. By adjusting the volume of the accommodation cavity, the grinding width of the flexible airbag 2 on the roll can be adjusted to adapt to rolls of different widths.

[0040] Specifically, in this embodiment, the pressing mechanism 53 includes a pressing member 531 and a support plate 532. The support plate 532 is fixedly arranged on the frame 1. The pressing member 531 passes through the support plate 532 and is threadedly connected to the support plate 532. The pressing member 531 is used to fixedly press the wiping consumable. Among them, two groups of pressing mechanisms 53 can be arranged oppositely in the width direction of the frame 1 parallel to the roll surface. One group of pressing mechanisms 53 is arranged on the surface of the first support block 51, and the other group of pressing mechanisms 53 is arranged on the surface of the second support block 52, so that the wiping consumable is sequentially wrapped around the surface of the first support block 51, the flexible airbag 2, and the surface of the second support block 52; in some other embodiments, two groups of pressing mechanisms 53 can be arranged oppositely on the frame 1 in the vertical direction. The group of pressing mechanisms 53 located above and the group of pressing mechanisms 53 located below are both in contact with the surfaces of the first support block 51 and the second support block 52 to fix and disassemble the wiping consumable and prevent the wiping consumable from being involved in the gap of the roll, causing damage to the rolling mill.

[0041] Specifically, in this embodiment, the wiping consumable is one of a sand belt, a silicon carbide grinding belt, and an alumina grinding belt. The sand belt, the silicon carbide grinding belt, or the alumina grinding belt can all make flexible contact with the roll surface, and has a high processing accuracy, and the abrasive grains on the surface have a good polishing and grinding effect. Of course, other materials of grinding belts can also be used for the wiping consumable as long as it is ensured that the wiping consumable can make sufficient contact with the roll surface, improving the grinding and cleaning efficiency of the roll cleaning equipment.

[0042] At the same time, the present invention also provides a roll system, including an upper roll 6, a lower roll 7, and two roll cleaning devices as described in any one of the above. The two roll cleaning devices are arranged at intervals in the vertical direction. One roll cleaning device is used to clean the roll surface of the upper roll 6, and the other roll cleaning device is used to clean the roll surface of the lower roll 7.

[0043] Such as Figure 7 AndFigure 8 As shown in the figure, during operation, the upper roller 6 and the lower roller 7 are started to rotate at a constant speed. At the same time, the detection mechanism 31 on each roller cleaning device detects the residue information on the roller surface and feeds it back to the controller. The controller controls the metering pump 33 to start according to the residue information, so that the grinding liquid flows out from the nozzle tube 34 at the position corresponding to the residue. The controller controls the opening degree of the pressure regulating valve 21 to complete the adjustment of the grinding pressure exerted by the flexible airbag 2 between the wiping consumable and the roller surface. According to Pascal's principle, the grinding pressure exerted by the flexible airbag 2 on the roller surface is calculated, and the calculation formula is as follows: ①; ②; Where F is the force exerted by the flexible airbag 2 on the roller, P is the gas pressure provided by the pressure regulating valve 21 to the flexible airbag 2, is the distance between two wave crests of the circular arc part where the flexible airbag 2 protrudes from the rolling surface, D is the projected length of the roller surface in the direction of the acting force, D 1 is the projected length of the roller surface of the upper roller 6 in the direction of the acting force, D 2 is the projected length of the roller surface of the lower roller 7 in the direction of the acting force. The effective acting width of the flexible airbag 2 on the roller is equal to the distance between two wave crests of the circular arc part where the flexible airbag 2 protrudes from the rolling surface , and is always greater than the actual contact width between the flexible airbag 2 and the roller .

[0044] As Figure 9 and Figure 10 shown, through the above calculation formula, the operator determines the force F required to remove foreign objects on the roller surface to be about 500N according to experience and experimental data, calculates the actual pressure given by the pressure regulating valve 21 to the flexible airbag 2, and inputs the pressure information into the controller. The controller adjusts the opening degree of the pressure regulating valve 21 to control the pressure inside the flexible airbag 2, ensuring the grinding effect of the roller system. Compared with the traditional roller system that is cleaned manually, in this application, the roller cleaning device cleans the adhesion of surface metal foreign objects on the upper roller 6 and the lower roller 7 during the working process respectively, ensuring the normal operation of the roller, and improving the production efficiency and service life of the roller.
