[0007] When the rolling mill needs to roll the steel plate, the controller controls the first motor on the support frame to start. The drive shaft in the first motor drives the rolling mill to rotate, and then the rolling mill performs rolling treatment on the steel plate. After the rolling mill finishes working, it is necessary to maintain and clean the rolling mill and detect the flatness of the rolling mill. Subsequently, the controller controls the second motor to start. The drive shaft in the second motor drives the rotating shaft to rotate. During the rotation of the rotating shaft, the rotating shaft drives the fixed body to rotate. The fixed body rotates towards the side close to the rolling mill. When the fixed body contacts the surface of the rolling mill, the controller controls the second motor to stop. Subsequently, the controller controls the cleaning device to start, and the cleaning device immediately performs maintenance and cleaning on the surface of the rolling mill. During the cleaning process, the surface of the rolling mill is detected, so as to realize the detection of the flatness of the surface of the rolling mill, thus ensuring the working state of the rolling mill and improving the quality of steel plate rolling.

[0008] Preferably, a second motor is further arranged on the support frame. The drive shaft in the second motor is connected to the rotating shaft. The fixed body is composed of a short arc block and a long arc plate. The short arc block is connected to the rotating shaft. The long arc plate is arranged above the short arc block. Baffles are symmetrically arranged on both sides of the fixed body. The distance between the baffles is equal to the length of the rolling mill. The baffles are in sliding and sealing connection with the rolling mill. A cleaning roller is arranged between the two baffles. The axis of the baffles coincides with the axis of the cleaning roller. The cleaning roller is rotationally connected to the short arc block.

[0009] Preferably, a water squeezing slope is arranged on the side of the short arc block close to the cleaning roller. The water squeezing slope contacts the surface of the cleaning roller. A slideway is arranged at the connection between the short arc block and the long arc plate. A plurality of water suction pipes are arranged in the long arc plate. The plurality of water suction pipes are arranged at equal intervals along the side of the long arc plate. A water pump is arranged in the water suction pipe. One end of the water suction pipe communicates with the slideway.

[0010] Preferably, a water delivery cavity is arranged on the side of the water suction pipe away from the slideway. The water delivery cavity communicates with the water suction pipe. The side wall of the water delivery cavity communicates with a water delivery port. A plurality of spray nozzles are arranged on the side of the water delivery cavity close to the cleaning roller. The plurality of spray nozzles are arranged at equal intervals along the side of the water delivery cavity.

[0011] Preferably, the rolling mill and the cleaning roller are in tangential contact. The spray nozzles are arranged directly above the contact position between the rolling mill and the cleaning roller.

[0012] Preferably, an arc-shaped block is arranged on the side of the long arc plate close to the rolling mill. The arc-shaped block is rotationally connected to the rolling mill. A water cutting edge is arranged on the side of the arc-shaped block close to the cleaning roller. A detection cavity is arranged on the side of the arc-shaped block close to the rolling mill. A plurality of flexible blocks are arranged in the detection cavity. The plurality of flexible blocks are arranged at equal intervals along the side of the detection cavity. The side of the flexible block close to the rolling mill is tapered. One end of the flexible block contacts the surface of the rolling mill. A pressure sensor is arranged on the flexible block.

[0013] Preferably, an air delivery cavity is arranged on one side of the water delivery cavity away from the water suction pipe. An air delivery port is arranged on the side wall of the air delivery cavity, and the air delivery port is connected to an external air source. An air delivery pipe is arranged on one side of the air delivery cavity close to the arc-shaped block. An air groove is arranged on one side of the flexible block close to the water cutting edge, and the air groove is communicated with the air delivery pipe.

[0014] Preferably, a sliding groove is arranged in the short arc block. A detection plate is slidably connected in the sliding groove. A micro motor is arranged in the detection plate. A transmission wheel is arranged on the driving shaft in the micro motor. The detection plate is slidably connected to the sliding groove through the transmission wheel. A transmission cavity is arranged in the short arc block. A toothed roll is rotatably connected in the transmission cavity. A third motor is arranged on the side wall of the transmission cavity, and the driving shaft in the third motor is connected to the toothed roll. A detection paper is slidably connected between the toothed roll and the detection plate. The length of the detection paper is equal to the circumference of the rolling roll. A visual sensor is arranged in the transmission cavity, and a flow sensor is also arranged on the detection plate. An auxiliary roll is arranged on one side of the short arc block away from the rolling roll;

[0015] When the rolling roll is in the working state, at this time, the long arc plate is in the vertical state, and the lowest end of the auxiliary roll on the short arc block is in the same straight line as the lowest end of the rolling roll. During the process of the rolling roll rolling the steel plate, the auxiliary roll performs auxiliary rolling on the rolled steel plate, thereby reducing the deformation amount caused by the stress on the steel plate;

[0016] When the rolling roll finishes the working state and needs to be maintained, the controller controls the second motor to start. The driving shaft in the second motor drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the fixed body to rotate. The fixed body rotates towards the side close to the rolling roll. When the fixed body rotates 90° towards the rolling roll and one end of the long arc plate is located above the rolling roll, the controller controls the second motor to stop;

[0017] When the fixed body rotates, the fixed body drives the baffle to rotate. When the baffle rotates, it contacts the side wall of the rolling roll. At the same time, the short arc block drives the cleaning roll to rotate. When the cleaning roll rotates, it contacts the surface of the rolling roll. Since the rolling roll and the cleaning roll are in tangential contact, the contact surface between the rolling roll and the cleaning roll is a straight line, and the baffle is slidably and sealingly connected to the rolling roll, so that a chamber with a sealed contact surface is formed among the rolling roll, the cleaning roll and the baffle. When the long arc plate rotates accordingly, the long arc plate drives the arc-shaped block to rotate. When the arc-shaped block rotates, the side of the arc-shaped block away from the long arc plate contacts the surface of the rolling roll;

[0018] Subsequently, the controller controls the water inlet to open. The external water source is transported to the water inlet through the pipeline, and then is transported to the water delivery cavity through the water inlet. When the water source fills the water delivery cavity, the controller controls the water inlet to close. Subsequently, the controller controls the spray port to open. The water source sprays towards the side close to the short arc block through the spray port, and the water source then falls into the chamber with a sealed contact surface formed among the rolling roll, the cleaning roll and the baffle;

[0019] Meanwhile, the controller controls the micro-motor in the detection board to start. The drive shaft in the micro-motor drives the transmission wheel to rotate. When the transmission wheel rotates, it drives the detection board to move. The detection board then drives the detection paper to move. The detection board moves towards the side away from the sliding groove, so that the detection board extends below a chamber with a sealed contact surface formed among the rolling roller, the cleaning roller and the baffle. Subsequently, the controller takes the line formed by the contact surface between the current rolling roller and the cleaning roller as the reference (i.e., the initial travel line), and the initial travel line corresponds to the detection paper below the chamber with a sealed contact surface formed among the rolling roller, the cleaning roller and the baffle to form a reference line. Then the controller controls the first motor to rotate. The drive shaft of the first motor drives the rolling roller to rotate. The rolling roller rotates towards the side close to the short arc block. At the same time, the controller controls the third motor on the transmission cavity to start. The drive shaft in the third motor drives the tooth coil to rotate. When the tooth coil rotates, it drives the detection paper to rotate. That is, when the rolling roller rotates one circle, the detection paper rotates one circle under the action of the tooth coil;

[0020] Subsequently, during the rotation of the rolling roller, the cleaning roller also rotates under the action of the rolling roller. During the rotation of the cleaning roller, it also cleans the rolling roller. Since water falls into the chamber with a sealed contact surface formed among the rolling roller, the cleaning roller and the baffle. When the rolling roller rotates, if there are depressions on the surface of the rolling roller, the contact line between the rolling roller and the cleaning roller is disconnected, so that the water in the chamber drops through the depressions. The water drops into the detection paper on the detection board. The flow sensor on the detection board converts the flow signal into an electrical signal and transmits it to the controller. The controller thus determines that there are damages on the surface of the rolling roller, thereby achieving the effect of detecting the flatness of the surface of the rolling roller, and thus ensuring the quality of the rolling of the steel plate by the rolling roller. When the detection paper moves into the transmission cavity, the visual sensor in the transmission cavity detects the detection paper. The visual sensor converts the image signal into an electrical signal and transmits it to the controller. The controller matches the moving distance of the initial travel line with the position of the water drop point on the detection paper, and thus can determine the position where there are damages on the rolling roller, so as to locate the position of the damage on the surface of the rolling roller, saving the time for the staff to detect the position of the damage on the surface of the rolling roller and improving the efficiency of the maintenance of the rolling roller;

[0021] And since heat is generated when the rolling roller rolls the steel plate, the water in the chamber not only cooperates with the cleaning roller to clean the surface of the rolling roller, but also cools down the rolling roller, so that the temperature on the rolling roller drops, improving the efficiency of cooling the rolling roller and also improving the utilization rate of the water source;

[0022] When the cleaning roller rotates, it drives the water source to move towards the side close to the water squeezing slope, so that the water source is transported to the slideway through the water squeezing slope. Subsequently, the water source is transported to the water suction pipe through the slideway. Then, the controller controls the water pump in the water suction pipe to start. The water pump extracts the water source and transports it to the water transmission cavity through the water suction pipe, enabling the reuse of the water source. After the maintenance of the rolling mill roll is completed, the controller controls the water outlet to open, and the water source in the water transmission cavity is transported out through the water outlet.

[0023] While the rolling mill roll is being cleaned, the rolling mill roll also drives a part of the water source to move towards the side close to the arc-shaped block. During the movement of the water source, the water source encounters the water cutting edge, and the water cutting edge immediately removes the water on the rolling mill roll, causing the water source to fall back into the chamber. Then, the controller controls the air inlet to open, and the external gas is immediately transported to the air transmission cavity through the air inlet. The gas is transported to the air pipe through the air transmission cavity and then to the air groove through the air pipe. When the roll wall of the rolling mill roll rotates to the detection cavity, the gas output from the air groove blows towards the roll wall of the rolling mill roll to blow away the residual water source on the rolling mill roll, keeping the surface of the rolling mill roll dry. At the same time, the flexible block contacts the surface of the rolling mill roll. Since the flexible block needs to apply a certain pressure to the rolling mill roll, the pressure sensor in the flexible block detects the pressure signal and converts the pressure signal into an electrical signal and transmits it to the controller. The controller uses this pressure as a reference. When the pressure signal becomes smaller, that is, when the flexible block encounters the crack gap on the surface of the rolling mill roll, the flexible block extends into the crack gap, thereby determining that there are cracks on the surface of the rolling mill roll, improving the detection quality of the surface of the rolling mill roll, and thus ensuring the maintenance quality of the rolling mill roll.

[0024] After a period of detection, maintenance, and cleaning, the controller controls the second motor to reverse. The second motor drives the rotating shaft to reverse, and the rotating shaft drives the fixed body to reset, causing the fixed body to leave the surface of the rolling mill roll.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0026] 1. If there are depressions on the surface of the rolling mill roll, the contact line between the rolling mill roll and the cleaning roller is disconnected, causing the water source in the chamber to fall through the depression. The water source falls from the chamber onto the test paper on the detection plate. The flow sensor on the detection plate converts the flow signal into an electrical signal and transmits it to the controller. The controller thus determines that there are damages on the surface of the rolling mill roll, achieving the effect of detecting the flatness of the surface of the rolling mill roll, thereby ensuring the quality of the rolling mill roll for rolling the steel plate. When the test paper moves into the transmission cavity, the visual sensor in the transmission cavity detects the test paper. The visual sensor converts the image signal into an electrical signal and transmits it to the controller. The controller matches the moving distance of the initial line of travel with the position of the water source landing point on the test paper, and can thus determine the position of the damage on the rolling mill roll, thereby positioning the position of the damage on the surface of the rolling mill roll, saving the time for the staff to detect the position of the damage on the surface of the rolling mill roll, and improving the efficiency of the maintenance of the rolling mill roll.

[0027] 2. Since heat is generated when the rolling mill rolls the steel plate, the water source in the chamber not only cooperates with the cleaning roller to clean the surface of the rolling mill, but also cools down the rolling mill, so that the temperature on the rolling mill drops, improving the cooling efficiency of the rolling mill and also the utilization rate of the water source.

[0045] The working principle of the present invention:

[0046] When the rolling roll 1 needs to roll the steel plate, the controller controls the first motor on the support frame to start. The drive shaft in the first motor drives the rolling roll 1 to rotate, and the rolling roll 1 then performs rolling treatment on the steel plate.

[0047] When the rolling roll 1 is in the working state, at this time the long arc plate 24 is in a vertical state. The lowest end of the auxiliary roll 233 on the short arc block 23 and the lowest end of the rolling roll 1 are on the same straight line. During the process of the rolling roll 1 rolling the steel plate, the auxiliary roll 233 performs auxiliary roll pressing on the rolled steel plate, thereby reducing the deformation amount of the steel plate caused by stress.

[0048] When the rolling mill roll 1 finishes its working state and needs to be maintained, the controller controls the second motor to start. The drive shaft in the second motor drives the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, it drives the fixed body 22 to rotate. The fixed body 22 rotates towards the side close to the rolling mill roll 1. When the fixed body 22 rotates 90° towards the rolling mill roll 1 and one end of the long arc plate 24 is located above the rolling mill roll 1, the controller controls the second motor to stop;

[0049] When the fixed body 22 rotates, the fixed body 22 drives the baffle 222 to rotate. When the baffle 222 rotates, it contacts the side wall of the rolling mill roll 1. At the same time, the short arc block 23 drives the cleaning roller 25 to rotate. When the cleaning roller 25 rotates, it contacts the surface of the rolling mill roll 1. Since the rolling mill roll 1 and the cleaning roller 25 are in tangential contact, the contact surface between the rolling mill roll 1 and the cleaning roller 25 is a straight line, and the baffle 222 is in sliding seal connection with the rolling mill roll 1, so that a chamber with a sealed contact surface is formed among the rolling mill roll 1, the cleaning roller 25 and the baffle 222. When the long arc plate 24 rotates accordingly, the long arc plate 24 drives the arc-shaped block 28 to rotate. When the arc-shaped block 28 rotates, the side of the arc-shaped block 28 away from the long arc plate 24 contacts the surface of the rolling mill roll 1;

[0050] Subsequently, the controller controls the water inlet 221 to open. The external water source is transported to the water inlet 221 through a pipeline, and then transported to the water delivery chamber 27 through the water inlet 221. When the water source fills the water delivery chamber 27, the controller controls the water inlet 221 to close. Subsequently, the controller controls the spray port 271 to open, and the water source sprays towards the side close to the short arc block 23 through the spray port 271. The water source then falls into the chamber with a sealed contact surface formed among the rolling mill roll 1, the cleaning roller 25 and the baffle 222;

[0051] At the same time, the controller controls the micro motor in the detection plate 32 to start. The drive shaft in the micro motor drives the transmission wheel to rotate. When the transmission wheel rotates, it drives the detection plate 32 to move. The detection plate 32 then drives the detection paper to move. The detection plate 32 moves towards the side away from the sliding groove 31, so that the detection plate 32 extends to the lower part of the chamber with a sealed contact surface formed among the rolling mill roll 1, the cleaning roller 25 and the baffle 222. Subsequently, the controller takes the line formed by the contact surface between the current rolling mill roll 1 and the cleaning roller 25 as the reference (i.e., the initial travel line), and forms a reference line with the detection paper below the chamber with a sealed contact surface formed among the rolling mill roll 1, the cleaning roller 25 and the baffle 222. Subsequently, the controller controls the first motor to rotate. The drive shaft of the first motor drives the rolling mill roll 1 to rotate. The rolling mill roll 1 rotates towards the side close to the short arc block 23. At the same time, the controller controls the third motor on the transmission cavity 33 to start. The drive shaft in the third motor drives the tooth roll 331 to rotate. When the tooth roll 331 rotates, it drives the detection paper to rotate, that is, when the rolling mill roll 1 rotates one circle, the detection paper rotates one circle under the action of the tooth roll 331;

[0052] Subsequently, during the rotation of the roller 1, the cleaning roller 25 also rotates under the action of the roller 1. During the rotation of the cleaning roller 25, it also cleans the roller 1. Since the water source falls between the roller 1, the cleaning roller 25 and the baffle 222 to form a chamber with a sealed contact surface. When the roller 1 rotates, if there are depressions on the surface of the roller 1, the contact line between the roller 1 and the cleaning roller 25 is disconnected, causing the water source in the chamber to drop through the depressions. The water source drops through the chamber into the test paper on the detection board 32. The flow sensor on the detection board 32 converts the flow signal into an electrical signal and transmits it to the controller. The controller thus determines that there are damages on the surface of the roller 1, achieving the effect of detecting the flatness of the surface of the roller 1, thereby ensuring the quality of the roller rolling of the steel plate by the roller 1. When the test paper moves into the transmission chamber 33, the vision sensor in the transmission chamber 33 detects the test paper. The vision sensor converts the image signal into an electrical signal and transmits it to the controller. The controller matches the moving distance of the initial line of the stroke with the position of the water source landing point on the test paper, and can thus determine the position where there are damages on the roller 1, so as to locate the position of the damage on the surface of the roller 1;

[0053] When the cleaning roller 25 rotates, it drives the water source to move towards the side close to the water squeezing slope 231, causing the water source to be conveyed to the slideway 232 through the water squeezing slope 231. Subsequently, the water source is conveyed to the water suction pipe 26 through the slideway 232. Then the controller controls the water pump in the water suction pipe 26 to start. The water pump extracts the water source and conveys it to the water transmission chamber 27 through the water suction pipe 26, enabling the water source to be reused. After the maintenance of the roller 1 is completed, the controller controls the water outlet 221 to open, and the water source in the water transmission chamber 27 is conveyed out through the water outlet 221;

[0054] While the roller 1 is being cleaned, the roller 1 also drives a part of the water source to move towards the side close to the arc-shaped block 28. During the movement of the water source, the water source encounters the water cutting edge 281, and the water cutting edge 281 immediately removes the water on the roller 1, causing the water source to fall back into the chamber again. Then the controller controls the air inlet 291 to open, and the external gas is immediately conveyed to the air transmission chamber 29 through the air inlet 291. The gas is conveyed to the air transmission pipe 292 through the air transmission chamber 29 and is conveyed to the air groove 302 through the air transmission pipe 292. When the roller wall of the roller 1 rotates to the detection chamber 30, the gas output from the air groove 302 blows towards the roller wall of the roller 1 to blow away the residual water source on the roller 1 and keep the surface of the roller 1 dry. At the same time, the flexible block 301 contacts the surface of the roller 1. Since the flexible block 301 needs to apply a certain pressure to the roller 1, the pressure sensor in the flexible block 301 detects the pressure signal and converts the pressure signal into an electrical signal and transmits it to the controller. The controller takes this pressure as a reference. When the pressure signal becomes smaller, that is, when the flexible block 301 encounters the crack gap on the surface of the roller 1, causing the flexible block 301 to extend into the crack gap, it is thus determined that there are cracks on the surface of the roller 1;

[0055] After a period of detection, maintenance, and cleaning, the controller controls the second motor to reverse. The second motor drives the rotating shaft 21 to reverse, and the rotating shaft 21 drives the fixed body 22 to reset, causing the fixed body 22 to leave the surface of the rolling mill 1.
