Description

Technical Field

[0001] This invention relates to the field of polishing and grinding equipment technology, and in particular to a device and method for using a steel roller in a polishing and grinding annealing kiln. Background Technology

[0002] During float glass production, annealing furnace steel rollers are prone to adhering to sulfides, oxides, tin impurities, tin ash impurities, rust spots, etc., causing defects such as scratches, dents, roller marks, and adhesives on the lower surface of the glass sheet, resulting in substandard glass quality. Restoring the flatness of the roller surface can ensure the quality of the finished glass product. Therefore, annealing furnace steel rollers need to undergo regular surface polishing and grinding.

[0003] Currently, the surface of steel rollers in annealing kilns is often polished manually with hand-held sandpaper, or using a combination of grinding and polishing wheels. Both of these methods are inefficient, and the steel rollers or grinding equipment move axially during the polishing process, which can easily create textures on the surface of the steel rollers, resulting in inconsistent polishing uniformity. Moreover, most processing equipment has a limited range of functions and cannot be adapted to the processing of steel rollers of different specifications, so its functionality needs to be improved. Summary of the Invention

[0004] This invention discloses a device and method for polishing and grinding steel rollers in annealing kilns, aiming to solve the technical problem that the functionality of traditional annealing kiln steel roller grinding equipment needs to be improved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for polishing and grinding steel rollers in an annealing kiln includes a lathe. Two sets of electrically controlled rollers are symmetrically arranged at the ends of the lathe. The steel rollers are mounted inside the lathe and rotated by the electrically controlled rollers. Two sets of positioning mechanisms are symmetrically arranged on both sides of the lathe. Each positioning mechanism includes steel rails mounted on both sides of the lathe. An electrically controlled slide is slidably mounted on the top of each steel rail. A rotating rod is rotatably mounted on the top of the electrically controlled slide. A bracket is fixedly mounted on the top of the rotating rod. An adjusting rod is slidably sleeved on the top of the bracket.

[0007] The top of the positioning mechanism is provided with a grinding mechanism for processing the steel roller. A long piece of sandpaper is additionally installed between the two grinding mechanisms. The grinding mechanism includes a machine base installed at the end of the adjusting rod. A rotating table is rotatably installed at the bottom of the machine base. A driven roller and a driving roller are symmetrically distributed inside the rotating table. A short piece of sandpaper is driven between the driven roller and the driving roller.

[0008] The positioning mechanism drives the grinding mechanism to move horizontally, and the optional long sandpaper is used to adapt and process steel rollers of different sizes.

[0009] Based on the traditional annealing kiln steel roller processing technology, a grinding mechanism with a positioning mechanism and coordinated movement is set up. The steel roller on the top of the lathe is rotated by an electrically controlled roller. The positioning mechanism presses the grinding mechanism onto the surface of the steel roller, and the distribution angle between the grinding mechanism and the steel roller is limited. When the positioning mechanism drives the grinding mechanism to move along the surface of the steel roller, the grinding area of ​​the steel roller can be increased by using a specific contact angle, while eliminating the grinding marks. This greatly improves the traditional grinding process. At the same time, the two separate grinding mechanisms in this equipment can be equipped with long sandpaper, so that they can operate together to handle larger steel rollers, thus greatly improving the functionality of traditional equipment.

[0010] In a preferred embodiment, a drive motor is fixedly mounted on the top of the electrically controlled slide, and the output end of the drive motor is horizontally fixed to the rotating rod.

[0011] By installing electrically controlled slides on both sides of the platform carrying the steel rollers, which are slidably mounted on the top of the rails, the horizontal movement of the electrically controlled slides, in conjunction with the rotation rod driving the bracket and adjusting rod to rotate, adjusts the relative position of the grinding mechanism. This, in turn, works with long sandpaper to change the working mode, maintains the integrity of the equipment's operation, and improves the functionality of traditional processes.

[0012] In a preferred embodiment, a stepper motor is fixedly installed on the top of the machine base. The output end of the stepper motor is vertically fixed to the middle of the rotating platform. After one set of the rotating platforms is rotated 180 degrees by the stepper motor, the short sandpaper on the two sets of rotating platforms can be removed and replaced with the long sandpaper. In this state, the active roller on one set of rotating platforms can change the position to change the curvature and tension of the long sandpaper.

[0013] By setting a rotating platform structure at the top of the adjusting rod and rotatably mounted at the bottom of the machine, the driven and driving rollers inside the rotating platform, along with the short sanding paper and the relative rotation of the rotating platform, limit the distribution angle of the short sanding paper and the steel roller. When the positioning mechanism drives the short sanding paper to move along the surface of the steel roller, the specific contact angle can be used to increase the sanding area of ​​the steel roller and effectively eliminate the sanding marks, thus greatly improving the traditional sanding process. At the same time, the two sets of short sanding papers in this equipment can be disassembled and long sanding paper can be installed, so that the two rotating platforms can be combined to deal with larger steel rollers, thus greatly improving the functionality of traditional equipment.

[0014] A method for using a steel roller device for polishing and grinding annealing kilns includes the following steps;

[0015] S1: The worker uses a crane to place the steel roller of the annealing kiln to be polished on the top of the lathe, so that both ends of the steel roller are pressed into contact with the electrically controlled rollers respectively;

[0016] S2: When using short sandpaper for polishing, the two sets of positioning mechanisms are distributed at the end of the lathe. After the steel roller is set up, the worker starts the positioning mechanism, which drives the polishing mechanism to contact the surface of the steel roller.

[0017] S3: The positioning mechanism drives the grinding mechanism to move horizontally along the outside of the lathe, while the electrically controlled roller drives the steel roller to rotate, thereby using the grinding mechanism to grind the steel roller;

[0018] S4: When the worker is grinding the large steel roller, the worker can optionally install the long sandpaper between the two grinding mechanisms, and at the same time adjust the height of the positioning mechanism to drive the long sandpaper to press and contact the surface of the steel roller for grinding.

[0019] S5: This equipment adopts an inclined distribution structure in both normal operation and when the long sandpaper is installed, to increase the single-pass sanding area of ​​the steel roller.

[0020] As can be seen from the above, the equipment and method for polishing and grinding steel rollers in annealing kilns provided by the present invention have the following technical effects.

[0021] Based on the traditional annealing kiln steel roller processing technology, a grinding mechanism with a positioning mechanism and linkage movement is set up. The steel roller on the top of the lathe is rotated by an electrically controlled roller. In conjunction with the electrically controlled slide table structure slidably installed on the top of the rail, the electrically controlled slide table moves horizontally and drives the bracket and adjusting rod to rotate, thereby adjusting the relative position of the grinding mechanism. In turn, it is used with long sandpaper to change the working mode and achieve the following effects in sequence.

[0022] Firstly, when two rotating tables are equipped with short sandpaper, the relative rotation of the rotating tables can limit the distribution angle of the short sandpaper and the steel roller. When the positioning mechanism drives the short sandpaper to move along the surface of the steel roller, the specific contact angle can be used to increase the sanding area of ​​the steel roller and eliminate the sanding marks, thereby greatly improving the traditional sanding process.

[0023] Secondly, in this equipment, when the two sets of separately existing short sandpaper are disassembled and the long sandpaper is installed, the two rotating tables can be combined to operate together, thus working together to deal with the grinding of larger steel rollers, maintaining a constant contact area, and thus greatly improving the functionality of traditional equipment.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The equipment and method for polishing and grinding steel rollers in annealing kilns disclosed in this invention are mainly applied to scenarios where steel rollers of different sizes in annealing kilns are used for polishing and grinding.

[0037] Reference Figures 1 to 10 A device for polishing and grinding steel rollers in an annealing kiln includes a lathe 1. Two sets of electrically controlled rollers 2 are symmetrically arranged at the ends of the lathe 1. The steel rollers are mounted inside the lathe 1 and rotated by the electrically controlled rollers 2. Two sets of positioning mechanisms 3 are symmetrically arranged on both sides of the lathe 1. The positioning mechanism 3 includes steel rails 301 mounted on both sides of the lathe 1. An electrically controlled slide table 302 is slidably installed on the top of each steel rail 301. A rotating rod 303 is rotatably installed on the top of the electrically controlled slide table 302. A bracket 305 is fixedly installed on the top of the rotating rod 303. An adjusting rod 306 is slidably sleeved on the top of the bracket 305.

[0038] The top of the positioning mechanism 3 is provided with a grinding mechanism 4 for processing the steel roller. A long sandpaper 5 is additionally installed between the two grinding mechanisms 4. The grinding mechanism 4 includes a machine base 401 installed at the end of the adjusting rod 306. A rotating table 402 is rotatably installed at the bottom of the machine base 401. A driven roller 404 and a driving roller 405 are symmetrically distributed inside the rotating table 402. A short sandpaper 406 is connected between the driven roller 404 and the driving roller 405.

[0039] The positioning mechanism 3 drives the grinding mechanism 4 to move horizontally, and with the optional long sandpaper 5, it can be used to adapt and process steel rollers of different sizes.

[0040] In this embodiment: A worker uses a crane to mount the annealing kiln steel roller to be polished onto the top of lathe 1, ensuring that both ends of the roller are pressed into contact with the electrically controlled rollers 2. While using short sandpaper 406 for polishing, two positioning mechanisms 3 are positioned at the ends of lathe 1. After the steel roller is mounted, the worker activates the positioning mechanisms 3, which cause the short sandpaper 406 of the polishing mechanism 4 to contact the surface of the steel roller. The positioning mechanisms 3 cause the polishing mechanism 4 to move horizontally along the outer side of the lathe 1, while simultaneously the electrically controlled rollers 2 cause the steel roller to rotate. Then, the short sandpaper 406 of the grinding mechanism 4 is used to grind the steel roller. When the worker is grinding the large steel roller, the worker can remove the short sandpaper 406 and install the long sandpaper 5 between the two grinding mechanisms 4. At the same time, the height of the positioning mechanism 3 is adjusted to drive the long sandpaper 5 to press against the surface of the steel roller and grind it. When the equipment is running with the short sandpaper 406 and the long sandpaper 5 installed, the short sandpaper 406 and the long sandpaper 5 can be inclined to increase the single grinding area of ​​the steel roller.

[0041] Reference Figure 1 , Figures 3 to 4In a preferred embodiment, a drive motor 304 is fixedly mounted on the top of the electrically controlled slide 302, and the output end of the drive motor 304 is horizontally fixed to the rotating rod 303.

[0042] When using short sandpaper 406 for sanding, two sets of electrically controlled slides 302 are distributed at the same end of the lathe 1. After the steel roller is set up, the worker starts the electrically controlled slide 302. The electrically controlled slide 302 moves horizontally along the top of the steel rail 301. At the same time, the drive motor 304 drives the rotating rod 303 to rotate. The rotating rod 303 drives the bracket 305 and the adjusting rod 306 to rotate and drive the sanding mechanism 4 to contact the surface of the steel roller, so that the sanding mechanism 4 and the steel roller are in contact and moving at the same time.

[0043] The bracket 305 is threadedly connected to the top of a first locking knob 307. The first locking knob 307 presses against the side wall of the adjusting rod 306. By rotating the first locking knob 307 and pulling the adjusting rod 306, the adjusting rod 306 slides along the inside of the bracket 305, thereby changing the relative distance between the grinding mechanism 4 at the end of the adjusting rod 306 and the steel roller.

[0044] Furthermore, a hydraulic tank 308 is fixedly installed on the outside of the machine 401, and a nozzle 309 is connected through the top of the hydraulic tank 308. The nozzle 309 is used to spray cleaning fluid during the grinding process of this equipment to assist in grinding.

[0045] Reference Figures 3 to 6 In a preferred embodiment, a stepper motor 403 is fixedly installed on the top of the machine base 401. The output end of the stepper motor 403 is vertically fixed to the middle of the rotating table 402. After one set of rotating tables 402 is rotated 180 degrees by the stepper motor 403, the short sandpaper 406 on the two sets of rotating tables 402 can be removed and replaced with long sandpaper 5. In this state, the active roller 405 on one set of rotating tables 402 can change the curvature and tension of the long sandpaper 5 by changing its position.

[0046] The rotating rod 303 drives the bracket 305 and adjusting rod 306 to rotate, causing the rotating platform 402 to contact 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. At the same time, the stepper motor 403 located on the top of the machine base 401 operates synchronously, causing the rotating platform 402 to deflect, so that the two rotating platforms 402 are mirror-image distributed around the axis of the steel roller. The specific state is shown in the attached figure. Figure 7As shown, 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, this increases the polishing area and efficiency of the steel roller, and on the other hand, the relative angle of the two short sandpapers 406 cancels out the single texture generated by polishing. Here, the single texture refers to the fact that if only one set of short sandpapers 406 is used for polishing, as the electronically controlled slide 302 moves, a spiral texture in one direction is easily generated on the surface of the steel roller. However, by using two short sandpapers 406, which are distributed in a mirror manner and polished simultaneously, the texture generated can be effectively canceled out, and the two sets are used simultaneously, resulting in higher efficiency.

[0047] In addition, when this equipment grinds large steel rollers, the worker can remove the short sandpaper 406 located inside the two rotating tables 402, and after controlling one rotating table 402 to rotate 180 degrees, a long sandpaper 5 is fitted and installed inside the two rotating tables 402. This causes the driving roller 405 inside one rotating table 402 and the driven roller 404 inside the other rotating table 402 to support the long sandpaper 5, thereby grinding the large steel roller. The specific state is shown in the attached figure. Figure 9 As shown;

[0048] Furthermore, the tilt of the long sandpaper 5 is controlled by the tilt distribution and staggered front and rear positions of the two rotating tables 402. At this time, the two synchronously operating electronically controlled slides 302 can improve the grinding efficiency of the large steel roller by using the long sandpaper 5. Moreover, the electronically controlled slides 302 can run back and forth multiple times, and the tilt direction of the long sandpaper 5 can be changed each time to reduce the possible grinding marks. The specific state is shown in the attached figure. Figure 8 As shown.

[0049] Reference Figure 3 , Figure 5 and Figure 10 In a preferred embodiment, a connector 407 is horizontally inserted through the end of the drive roller 405. The connector 407 is rotatably mounted on the outside of the base 411 at the top of the rotary table 402. A motor 408 is fixedly mounted on the outside of the connector 407. The output end of the motor 408 extends horizontally into the interior of the connector 407 and is connected to the drive roller 405 by a belt 409. The belt 409 is located inside the connector 407. A third locking knob 410 is installed at the base 411 at the top of the rotary table 402. The base 411 and the connector 407 are installed by the third locking knob 410.

[0050] During normal operation, the motor 408 drives the active roller 405 to rotate via the belt 409, which in turn drives the short sandpaper 406 to rotate synchronously for sanding. During the sanding process using the long sandpaper 5, after the worker rotates one of the rotating tables 402 180 degrees and places the long sandpaper 5 between the two rotating tables 402, the worker can loosen the third locking knob 410 to allow the connecting piece 407 to rotate around the base 411, thereby adjusting the position and angle of the active roller 405 at the other end of the connecting piece 407. After adjusting the angle, the third locking knob 410 can be tightened to maintain stability, allowing the active roller 405 to press against one end of the long sandpaper 5. This allows for adjustment of the curvature of the long sandpaper 5 to match the surface curvature of the large steel roller. This also improves the tension of the long sandpaper 5, ensuring a better driving effect. The driven roller 404 at the other end of the long sandpaper 5 can also be adjusted to further increase tension. During this process, only one set of driving rollers 405 is responsible for driving the long sandpaper 5, while the other set is responsible for passive transmission. The purpose of providing driving force through only one set of driving rollers 405 is to avoid a speed difference caused by both sets of driving rollers 405 simultaneously, which would lead to faster wear of the long sandpaper 5 and reduced transmission efficiency. Therefore, after rotating the turntable 402 180 degrees, one end of the long sandpaper 5 is fitted onto the surface of the driving roller 405, and the other end onto the surface of the driven roller 404. This avoids the speed difference problem and allows the long sandpaper 5 to have a larger sanding range, improving sanding efficiency. For details, please refer to the appendix. Figure 6 .

[0051] The rotating table 402 has an adjustment groove 4042 through its side wall. The driven roller 404 is threadedly connected to a second locking knob 4041. The second locking knob 4041 and the adjustment groove 4042 are in contact. By rotating the second locking knob 4041 and moving the driven roller 404, the worker can make the driven roller 404 slide along the inside of the adjustment groove 4042, thereby adjusting the relative distance between the driven roller 404 and the driving roller 405.

[0052] 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.

[0053] 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.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
