[0028] In the embodiment: the worker erects the annealing furnace steel roller to be polished on the top of lathe 1 by crane, and the two ends of the steel roller are in contact with the electric control roller 2; in the state of polishing by short abrasive paper 406, the two positioning mechanisms 3 are distributed at the ends of lathe 1, after the steel roller is erected, the worker starts the positioning mechanism 3, the positioning mechanism 3 drives the short abrasive paper 406 of polishing mechanism 4 to contact the surface of the steel roller; the positioning mechanism 3 drives the polishing mechanism 4 to move horizontally along the outside of lathe 1, and the electric control roller 2 drives the steel roller to rotate, and then the short abrasive paper 406 of polishing mechanism 4 is used to polish the steel roller; when the worker polishes the large steel roller, the worker can disassemble the short abrasive paper 406 and install the long abrasive paper 5 between the two polishing mechanism 4, and adjust the height of the positioning mechanism 3 to drive the long abrasive paper 5 to contact and polish the surface of the steel roller; when the short abrasive paper 406 and the long abrasive paper 5 are used in the equipment, the short abrasive paper 406 and the long abrasive paper 5 can be inclinedly distributed to increase the single polishing area of the steel roller.

[0029] Reference Figure 1 、 Figures 3 to 4 In a preferred embodiment, a drive motor 304 is fixedly installed on the top of the electric control sliding table 302, and the output end of the drive motor 304 is horizontally fixed to the rotating rod 303.

[0030] In the state of polishing using short abrasive paper 406, two groups of electric control sliding table 302 are distributed at the same end of lathe 1, after the completion of the erection of steel roller, the worker starts electric control sliding table 302, electric control sliding table 302 moves horizontally along the top of steel rail 301, at the same time, driving motor 304 drives rotating rod 303 to rotate, rotating rod 303 drives support 305 and adjusting rod 306 to rotate and drives polishing mechanism 4 to contact the surface of steel roller, so that polishing mechanism 4 and steel roller move while contacting.

[0031] Wherein, the top of support 305 is threadedly connected with first locking knob 307, first locking knob 307 is in contact with the side wall of adjusting rod 306 by extrusion, by rotating first locking knob 307 and pulling adjusting rod 306, adjusting rod 306 slides along the inside of support 305, thereby changing the relative distance between polishing mechanism 4 at the end of adjusting rod 306 and steel roller.

[0032] Further, the outside of machine table 401 is fixedly installed with hydraulic tank 308, the top of hydraulic tank 308 is throughly connected with nozzle 309, nozzle 309 is used to spray cleaning liquid during the polishing of the device to assist polishing.

[0033] Referring to Figures 3 to 6 In a preferred embodiment, the top of machine table 401 is fixedly installed with stepping motor 403, the output end of stepping motor 403 is vertically fixed to the middle of rotating table 402, one group of rotating table 402 can be disassembled after rotating 180 degrees by stepping motor 403, and long abrasive paper 5 is selected instead of short abrasive paper 406 on the other group of rotating table 402, in this state, driving roller 405 on one group of rotating table 402 can change the arc and tension of long abrasive paper 5 by changing the position.

[0034] Rotating rod 303 drives support 305 and adjusting rod 306 to rotate and drives rotating table 402 to contact the surface of steel roller, so that short abrasive paper 406 outside driven roller 404 and driving roller 405 contacts steel roller, at the same time, stepping motor 403 on the top of machine table 401 operates synchronously to drive rotating table 402 to deflect, so that two rotating tables 402 are mirror image distributed around the axis of steel roller, the specific state is shown in the attached Figure 7As shown, at this time, accompanied by the movement of the electric control sliding table 302, and the rotation of the steel roller driven by the electric control roller 2, the short abrasive paper 406 located inside the two rotating tables 402 will contact the steel roller at an oblique angle, on the one hand, improving the polishing area and efficiency of the steel roller, on the other hand, using the relative angle of the two short abrasive papers 406 to offset the single line generated by polishing, here the single line refers to, if only one set of short abrasive paper 406 is used for polishing, with the movement of the electric control sliding table 302, the steel roller surface is easy to produce a spiral line in one direction, and two short abrasive papers 406 are used to polish at the same time in a mirror image manner, the generated line can be well offset, and two groups are polished at the same time, the efficiency is higher; In addition, when the device polishes large steel rollers, workers can disassemble the short abrasive paper 406 located inside the two rotating tables 402, and control one rotating table 402 to rotate 180 degrees, then install a long abrasive paper 5 in the inside of the two rotating tables 402, so that the driving roller 405 in one of the rotating tables 402 and the driven roller 404 in the other rotating table 402 support the long abrasive paper 5, thereby polishing the large steel roller, the specific state is shown in the accompanying Figure 9 In addition, the inclined distribution and the front and rear position of the two rotating tables 402 are used to control the inclination of the long abrasive paper 5, at this time, the two electric control sliding tables 302 running synchronously can improve the polishing efficiency of the large steel roller by using the long abrasive paper 5, and the electric control sliding table 302 can run back and forth multiple times, each time the running can change the inclination direction of the long abrasive paper 5, which is used to reduce the polishing lines that may be generated, the specific state is shown in the accompanying Figure 8

[0035] Referring to Figure 3 , Figure 5 and Figure 10 In a preferred embodiment, the end of the driving roller 405 is horizontally penetrated by a connecting piece 407, the connecting piece 407 is rotatably installed outside the base 411 on the top of the rotating table 402, the outer side of the connecting piece 407 is fixedly installed with a motor 408, the output end of the motor 408 is horizontally penetrated into the inside of the connecting piece 407, and the driving roller 405 is drivingly connected with the belt 409, the belt 409 is located in the inside of the connecting piece 407, the base 411 on the top of the rotating table 402 is installed with a third locking knob 410, and the base 411 and the connecting piece 407 are installed through the third locking knob 410.

[0036] ​​When the device is in normal operation, the motor 408 drives the driving roller 405 to rotate through the belt 409, and the short abrasive paper 406 connected to the driving roller 405 rotates synchronously and is polished. During the process of polishing by the long abrasive paper 5, when the worker turns the rotating table 402 by 180 degrees and connects the long abrasive paper 5 between the two rotating tables 402, the worker can loosen the third locking knob 410 to rotate the connecting piece 407 around the base 411, so as to adjust the position angle of the driving roller 405 at the other end of the connecting piece 407. After adjusting the angle, the third locking knob 410 can be locked to keep stable, and the driving roller 405 is pressed on one end of the long abrasive paper 5. In this way, the curvature of the long abrasive paper 5 can be adjusted to adapt to the curvature of the large steel roller surface, and the tension of the long abrasive paper 5 can be improved to ensure the driving effect. The position of the driven roller 404 at the other end of the long abrasive paper 5 can also be adjusted to further improve the tension. During this process, only one set of driving roller 405 is responsible for driving the long abrasive paper 5, and the other set of driving roller 405 is responsible for passive transmission. The purpose of providing driving force by only one set of driving roller 405 is to avoid the speed difference caused by the simultaneous driving of the two sets of driving roller 405, which leads to the accelerated wear of the long abrasive paper 5 and the decreased transmission efficiency. Therefore, after the rotating table 402 is turned by 180 degrees, one end of the long abrasive paper 5 is connected to the surface of the driving roller 405, and the other end is connected to the surface of the driven roller 404. This can avoid the problem of speed difference, and can also make the polishing range of the long abrasive paper 5 larger and improve the polishing efficiency. For details, please refer to the accompanying drawings. Figure 6 .

[0037] The side wall of the rotating table 402 is provided with an adjusting groove 4042, and the side surface of the driven roller 404 is threadedly connected with a second locking knob 4041. The second locking knob 4041 is in extrusion contact with the adjusting groove 4042. The worker rotates the second locking knob 4041 and pushes the driven roller 404 to make the driven roller 404 slide along the inside of the adjusting groove 4042, so as to adjust the relative distance between the driven roller 404 and the driving roller 405.

[0038] Working Principle: During use, the worker uses a crane to mount the annealing kiln steel roller to be polished onto the top of the lathe 1, allowing both ends of the steel roller to press into contact with the electrically controlled rollers 2. While using short sandpaper 406 for polishing, two sets of electrically controlled slides 302 are positioned at the same end of the lathe 1. After the steel roller is mounted, the worker starts the electrically controlled slides 302, which move horizontally along the top of the rail 301. Simultaneously, the drive motor 304 rotates the rotating rod 303. The rotating rod 303 causes the bracket 305 and adjusting rod 306 to rotate, bringing the rotating table 402 into contact with the surface of the steel roller. This causes the short sandpaper 406, located outside the driven roller 404 and the driving roller 405, to contact the steel roller. Simultaneously, the stepper motor 403 at the top of the machine base 401 rotates synchronously, causing the rotating table 402 to deflect. The two rotating tables 402 are mirror-image positioned around the axis of the steel roller, as shown in the attached diagram. Figure 7 As shown, at this time, with the movement of the electronically controlled slide 302 and the rotation of the steel roller driven by the electronically controlled roller 2, the short sandpaper 406 located inside the two rotating tables 402 will contact the steel roller at an oblique angle. On the one hand, it increases the polishing area of ​​the steel roller, and on the other hand, it uses the relative angle of the two short sandpapers 406 to cancel out the polishing texture. Furthermore, when this equipment grinds large steel rollers, the worker can disassemble the short sandpaper 406 located inside the two rotating tables 402, control one rotating table 402 to rotate 180 degrees, and then attach one end of a long sandpaper 5 to the drive roller 405 of one of the rotating tables 402, and attach the other end of the long sandpaper 5 to the driven roller 404 inside the other rotating table 402. The staggered arrangement of the two rotating tables 402 is used to control the tilt of the long sandpaper 5. At this time, the two synchronously operating electrically controlled slides 302 can use the long sandpaper 5 to grind the entire steel roller. The specific details are shown in the attached diagram. Figure 8 Appendix Figure 9 As shown, the polishing process is complete.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
