Description

Technical Field

[0001] The invention relates to an annealing furnace, and in particular to an annealing furnace roller table fine adjustment device and method. Background Art

[0002] Roller annealing furnace is mainly used for annealing of flat glass, such as flat glass produced by float glass and flat drawing glass, as well as annealing of rolled glass, wired glass and decorative glass;

[0003] The annealing furnace comprises an annealing furnace shell, and a plurality of rollers are arranged inside the annealing furnace for transmitting the glass ribbon. The outer side of the annealing furnace shell is a transmission side at one side, and the transmission side has a gear train and a driving component for driving the rollers to rotate, and the other side is a non-transmission side.

[0004] The production process of float glass substrate is as follows: various raw materials are melted in the kiln, formed in the tin bath, and then enter the annealing kiln. The temperature of ordinary float glass ribbon entering the annealing kiln is about 600℃, at which time the glass has been formed and enters the annealing kiln. The internal transmission structure of the annealing kiln is that the glass ribbon is pulled by hundreds of rollers and conveyed to the cold end for cutting.

[0005] At present, the glass ribbon is easy to deviate in the annealing furnace roller. The main reason for the large deviation of the annealing furnace roller is that the center line of the annealing furnace shell is based on the center line of the annealing furnace shell. The center lines of the rollers are not parallel, which easily causes the glass ribbon to deviate in one direction along with the rollers, thereby causing the glass ribbon to contact the annealing furnace shell, affecting the normal production of glass. At present, for the roller after deviation, the calibration process usually requires a benchmark, but currently it is only adjusted based on the visual inspection or feeling of the adjuster, which cannot guarantee the accuracy of the calibration, nor the uniformity of the calibration, and the parallelism requirements are still not met after calibration.

[0006] For example, in the application No. 201520164874.0, an anti-deviation device for a foam glass annealing furnace includes: an anti-deviation retaining ring slidably mounted on a conveying roller to block the edge of a conveying mesh belt; a fastening sleeve mounted on the end of the conveying roller to prevent the anti-deviation retaining ring from coming out; and a fixing bolt connected between the fastening sleeve and the conveying roller. Anti-deviation is achieved through the hard connection of the retaining ring, but no solution is given for how to correct the deviation after it occurs.

[0007] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0008] The technical problem to be solved by the present invention is: how to solve the problem that the existing correction method for rollers after the roller table deviates cannot meet the parallelism requirements of the rollers and still cannot solve the problem of glass ribbon deviation.

[0009] The present invention solves the above technical problems through the following technical means:

[0010] The annealing furnace roller fine adjustment device comprises a positioning part, a connecting part, a rocker part and a reference wire rope, wherein the positioning part comprises a positioning hole arranged at the end of the roller and a positioning shaft arranged at one end of the connecting part, the positioning shaft is inserted into the positioning hole for connection, and the other end of the connecting part is connected with the end of the rocker part, the rocker part comprises a rocker, a plate and an adjusting rod assembly, the rocker is perpendicular to the connecting part, a plurality of mounting positions for mounting the adjusting rod assembly are provided on the rocker, the adjusting rod assembly can be adjustably mounted on the rocker, the plate is connected to the end of the adjusting rod assembly in parallel with the rocker, the reference wire rope is parallel to the center line of the annealing furnace shell, and the reference wire rope is arranged between the annealing furnace shell and the rocker part.

[0011] The present invention sets a reference steel wire rope so that it is parallel to the center line of the annealing furnace shell, and uses the reference steel wire rope as a reference to judge the parallelism of the roller. The positioning part realizes axial positioning and installation of the fine adjustment device and the roller end, and the connecting part realizes fixed connection between the fine adjustment device and the roller end. The swing rod is perpendicular to the connecting part, and the plate is parallel to the swing rod. Therefore, the plate and the roller are in a vertical state. Whether the roller is perpendicular to the reference steel wire rope can be judged by whether the plate and the reference steel wire rope are parallel or overlapped. If they are not parallel or overlapped, the roller needs to be adjusted. If they are parallel or overlapped, the roller is perpendicular to the center line of the annealing furnace shell, and so on. The center lines of all rollers are perpendicular to the center line of the shell, ensuring that the center lines of the rollers are parallel. The roller fine adjustment device provided by the present invention can accurately detect whether the roller is perpendicular to the center line of the annealing furnace shell, and then adjust it, and can also be re-calibrated. The inspection is accurate, providing a basis for ensuring the parallelism of multiple rollers, thereby ensuring that the deviation of the glass ribbon is small and the normal transportation of the glass ribbon is guaranteed.

[0012] Preferably, the connecting part includes a connecting shell, a first magnet with permanent magnetism, and a second magnet made of soft magnetic material. The interior of the connecting shell is hollow, the first magnet is in a bar shape, the first magnet is placed in the connecting shell, and the second magnet is embedded in the shell wall of the connecting shell. The second magnet is located along the axial direction of the positioning axis. When the first magnet and the second magnet are magnetized, the second magnet is located at both ends of the first magnet.

[0013] Soft magnetic material refers to a ferrite material that is easy to magnetize and demagnetize in a weak magnetic field. By rotating the first magnet, when the two poles (N or S) of the first magnet are in a horizontal direction, the N or S pole of the first magnet faces the second magnet, and the second magnet is magnetized. It has strong magnetism in this direction and can be used to attract the surface of the roller shaft head. When the first magnet is rotated 90 degrees, when the two poles of the magnet are in the up and down directions, and the middle of NS faces the second magnet, there is only very little magnetism in the middle of the long strip magnet, which can be ignored. The second magnet will not be magnetized, so there is no magnetic force in the connecting part at this time, and it can be easily removed from the roller shaft head. The present invention utilizes the characteristics of fast magnetization and demagnetization of soft magnetic materials and the characteristics of extremely weak magnetic field in the middle part of the first magnet and extremely strong magnetic field at both ends to achieve easy fixing and disassembly.

[0014] Preferably, the device further comprises a knob, which is connected to the first magnet and is disposed outside the connection housing. The knob is used to control the direction of the first magnet.

[0015] Preferably, the adjusting rod assembly includes an adjusting rod and an adjusting nut, the rocker rod is provided with a plurality of through holes, both ends of the adjusting rod are threaded, the adjusting rod passes through the through holes and both ends extend out, and the adjusting nut is connected to both ends of the adjusting rod.

[0016] By screwing the adjusting nuts on both sides, the extended length of the adjusting rod is adjusted, and then the position of the plate is adjusted.

[0017] Preferably, it further comprises an extension rod, wherein the extension rod is connected to the end of the swing rod through a pin, and the extension rod and the swing rod are located on the same axis.

[0018] Generally speaking, the longer the pendulum is and the farther the plate is from the roller, the larger the angle between the plate and the reference wire rope can be, and the more the degree of roller inclination can be known, which facilitates precise adjustment. The length of the pendulum can be adaptively adjusted according to the requirements for accuracy, as well as whether to increase the length of the extension rod and the extension rod. When the pendulum is not used for detection, the straightness of the pendulum can also be checked by overlapping the extension rod with the reference wire rope.

[0019] Preferably, the extension rod is provided with a plurality of mounting positions for mounting the adjusting rod assembly, the adjusting rod assembly is adjustably mounted on the extension rod, and the end of the adjusting assembly on the extension rod is connected to the flat plate.

[0020] The basic function of the extension rod is the same as that of the rocker rod. Both can be used to check the parallelism of the rollers. The increased length can also improve the accuracy of the calibration.

[0021] The present invention also provides a method for fine-tuning an annealing kiln roller table, which uses the above-mentioned annealing kiln roller table fine-tuning device, and comprises the following steps:

[0022] S01: Based on the center line of the annealing furnace shell, the reference steel wire ropes are arranged on both sides of the annealing furnace, so that the reference steel wire ropes are parallel to the center line of the annealing furnace shell, and the height of the rollers on the transmission side is adjusted according to the original design size. After the adjustment of the transmission side is completed, the height of the rollers on the transmission side is used as the adjustment reference of the non-transmission side;

[0023] S02: insert the positioning shaft into the positioning hole, and fix the fine adjustment device to the roller;

[0024] S03: Adjust the adjustment rod assembly to bring the flat plate and the reference wire rope closer, observe whether the flat plate and the reference wire rope are parallel or overlapped, then rotate the connecting roller of the swing rod part 180°, observe whether the flat plate and the reference wire rope are parallel or overlapped, if not, it is judged that the rollers are not parallel, and then adjust until the flat plate and the reference wire rope are parallel or overlapped;

[0025] S04: By adjusting the rod assembly and the flat plate to be installed at different installation positions of the swing rod, multiple tests are performed to check whether the flat plate and the reference wire rope are parallel or coincident;

[0026] S05: Adjust all rollers in sequence according to steps S02-S04 until all rollers are parallel.

[0027] The method of the present invention can set the length of the swing rod according to the accuracy requirement, has strong adaptability, and can accurately and quickly test, thus providing a basis for subsequent adjustments.

[0028] Preferably, the connecting part includes a connecting shell, a first magnet with permanent magnetism, and a second magnet made of soft magnetic material. The interior of the connecting shell is hollow, the first magnet is in a bar shape, the first magnet is placed in the connecting shell, the second magnet is embedded in the shell wall of the connecting shell, and the second magnet is located along the axial direction of the positioning shaft. When the first magnet and the second magnet are magnetized, the second magnet is located at both ends of the first magnet; in step S02, after the positioning shaft is inserted into the positioning hole, the first magnet is rotated so that it is on the same line as the second magnet, and the positioning shaft and the roller are fixedly connected by magnetic force.

[0029] Preferably, it also includes an extension rod. In step S02, before the positioning shaft is inserted into the positioning hole, the extension rod is connected to the rocker arm through a pin shaft, the rocker arm and the extension rod are brought close to the reference wire rope, and the straightness of the rocker arm is checked. After the inspection is completed, the extension rod is disassembled.

[0030] Preferably, after step SO4 is completed, the extension rod is connected to the swing arm through the pin again, and the adjustment assembly is connected to the flat plate on the extension rod for verification.

[0031] The advantages of the present invention are:

[0032] (1) The present invention sets a reference steel wire rope so that it is parallel to the center line of the annealing furnace shell, and uses the reference steel wire rope as a reference to judge the parallelism of the roller. The positioning part realizes the axial positioning installation of the fine adjustment device and the roller end, and the connecting part realizes the fixed connection between the fine adjustment device and the roller end. The swing rod is perpendicular to the connecting part, and the plate is parallel to the swing rod. Therefore, the plate and the roller are in a vertical state. Whether the roller is perpendicular to the reference steel wire rope can be judged by whether the plate and the reference steel wire rope are parallel or overlapped. If they are not parallel or overlapped, the roller needs to be adjusted. If they are parallel or overlapped, the roller is perpendicular to the center line of the annealing furnace shell. By analogy, all the center lines of the rollers are perpendicular to the center line of the shell, ensuring that the center lines of the rollers are parallel. The roller fine adjustment device provided by the present invention can accurately check whether the roller is perpendicular to the center line of the annealing furnace shell, and then adjust it, and can also perform recalibration, quickly and accurately adjust the parallelism between the rollers, ensure the correct roller spacing, provide a basis for ensuring the parallelism of multiple rollers, and thereby ensure that the deviation of the glass ribbon is small and the normal transportation of the glass ribbon is ensured;

[0033] (2) Soft magnetic material refers to a ferrite material that is easy to magnetize and demagnetize in a weak magnetic field. By rotating the first magnet, when the two poles (N or S) of the first magnet are in a horizontal direction, the N or S pole of the first magnet faces the second magnet, and the second magnet is magnetized. In this direction, it has strong magnetism and can be used to attract the surface of the roller shaft head. When the first magnet is rotated 90 degrees, when the two poles of the magnet are in the up and down directions, and when the middle of NS faces the second magnet, there is only a very small magnetism in the middle of the long strip magnet, which can be ignored. The second magnet will not be magnetized, so there is no magnetic force in the connection at this time, and it can be easily removed from the roller shaft head. The present invention utilizes the characteristics of fast magnetization and demagnetization of soft magnetic materials and the characteristics of extremely weak magnetic field in the middle part of the first magnet and extremely strong magnetic field at both ends, which can achieve easy fixing and disassembly;

[0034] (3) Generally, the longer the pendulum rod is, the farther the plate is from the roller, the larger the angle between the plate and the reference wire rope can be, and the more the degree of roller inclination can be known, which is convenient for precise adjustment. The length of the pendulum rod can be adaptively adjusted according to the requirements for accuracy, and whether to increase the length of the extension rod and the extension rod can be adjusted; when the pendulum rod is not used for detection, the extension rod can also be used to coincide with the reference wire rope to check the straightness of the pendulum rod, which has strong adaptability;

[0035] (4) The method of the present invention can set the length of the pendulum rod according to the accuracy requirements, has strong adaptability, and can perform accurate and fast inspections, thus providing a basis for subsequent adjustments. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1:

[0045] like Figure 1 As shown, the annealing furnace roller fine adjustment device is installed at the end of the roller 1, including a positioning part, a connecting part 2, a rocker part 3, and a reference wire rope 4. The positioning part includes a positioning hole 11 arranged at the end of the roller 1, and a positioning shaft 21 arranged at one end of the connecting part 2. The positioning shaft 21 is inserted into the positioning hole 11 for connection, and the other end of the connecting part 2 is connected to the end of the rocker part 3. The rocker part 3 includes a rocker 31, a plate 32, and an adjusting rod assembly. The rocker 31 is perpendicular to the connecting part 2. The rocker 31 is provided with a plurality of mounting positions for mounting the adjusting rod assembly. The adjusting rod assembly can be adjusted and mounted on the rocker. The plate 32 is connected to the end of the adjusting rod assembly in parallel with the rocker 31. The reference wire rope 4 is parallel to the center line of the annealing furnace shell, and the reference wire rope 4 is arranged between the annealing furnace shell and the rocker part 3.

[0046] When the annealing furnace is first set up, the center line of the annealing furnace shell is marked on the ground or bottom plate, and a reference wire rope 4 is pulled between the annealing furnace shell and the swing arm part 3, and the original mark is used as a reference to ensure that the reference wire rope 4 is parallel to the center line of the annealing furnace shell.

[0047] The positioning part is a positioning hole 11 machined on the shaft head of the roller 1, which is positioned by matching with the positioning shaft 21 machined out of the roller 1. The two require high precision and high concentricity. At the same time, the rocker 31 and the positioning shaft 21 must be vertical.

[0048] Combination Figure 1 , Figure 2 As shown, the connecting part 2 includes a connecting shell, a first magnet 22 with permanent magnetism, a second magnet 23 made of soft magnetic material, and a knob 24. The interior of the connecting shell is empty. The first magnet 22 is in a strip shape. The first magnet 22 is placed in the connecting shell. The second magnet 23 is embedded in the shell wall of the connecting shell. The second magnet 23 is located along the central axis direction of the positioning shaft 21. When the first magnet 22 and the second magnet 23 are magnetized, the second magnet 23 is located at both ends of the first magnet 22. The knob 24 is connected to the first magnet 22 and is placed outside the connecting shell. The knob 24 is used to control the rotation direction of the first magnet 22.

[0049] In this embodiment, the first magnet 22 is a permanent magnet or a constant magnet, and the soft magnetic material refers to a ferrite material that is easily magnetized and easily demagnetized in a weak magnetic field;

[0050] like Figure 2 As shown, by rotating the first magnet 22, when the two poles (N or S) of the first magnet 22 are in a horizontal direction, when the N or S pole of the first magnet 22 is facing the second magnet 23, the second magnet 23 is magnetized, and has a strong magnetic field in this direction, which can be used to attract the surface of the shaft head of the roller 1, as shown in FIG. Figure 3 As shown, when the first magnet 22 is rotated 90 degrees, when the two poles of the first magnet 22 are in the up and down directions, and when the middle of NS is facing the second magnet 23, there is only very little magnetism in the middle of the long strip of the first magnet 22, which can be ignored. At this time, the second magnet 23 will not be magnetized, so the connecting part 2 has no magnetic force and can be easily removed from the shaft head of the roller 1. This embodiment utilizes the characteristics of fast magnetization and demagnetization of soft magnetic materials and the characteristics of extremely weak magnetic field in the middle part of the first magnet 22 and extremely strong magnetic field at both ends, which can achieve easy fixing and disassembly.

[0051] The rocker portion 3 includes a rocker 31, a plate 32, and an adjusting rod assembly. The adjusting rod assembly includes an adjusting rod 33 and an adjusting nut 34. The rocker 31 is provided with a plurality of through holes. Both ends of the adjusting rod 33 have threads. The adjusting rod 33 passes through the through holes and extends at both ends. The adjusting nut 34 is connected to both ends of the adjusting rod 33. By screwing the adjusting nuts 34 on both sides, the extending length of the adjusting rod 33 is adjusted, and then the position of the plate 32 is adjusted. The adjustment of the threaded fit has higher precision and a self-locking function.

[0052] In this embodiment, a reference steel wire rope 4 is arranged to be parallel to the center line of the annealing furnace shell. The reference steel wire rope 4 is used as a reference to judge the parallelism of the roller 1. The positioning part realizes the axial positioning installation of the fine adjustment device and the end of the roller 1. The first magnet 22 magnetizes and demagnetizes the second magnet 23 to realize the fixed connection and removal of the fine adjustment device and the end of the roller 1.

[0053] The swing rod 31 is perpendicular to the positioning shaft 21, and the flat plate 32 is parallel to the swing rod 31. Therefore, the flat plate 32 and the roller 1 are in a perpendicular state. Whether the roller 1 is perpendicular to the reference steel wire rope 4 can be judged by whether the flat plate 32 is parallel to or overlaps with the reference steel wire rope 4. If the flat plate 32 is not parallel to or overlaps with the reference steel wire rope 4, the roller 1 needs to be adjusted. If they are parallel or overlap, the roller 1 is perpendicular to the center line of the annealing furnace shell. By analogy, the center lines of all rollers 1 are perpendicular to the center line of the shell, ensuring that the center lines of all rollers 1 are parallel.

[0054] The roller fine-tuning device provided in this embodiment can accurately check whether the roller 1 is perpendicular to the center line of the annealing furnace shell, and then adjust it, and can also perform recalibration. The inspection is accurate, providing a basis for ensuring the parallelism of multiple rollers 1, thereby ensuring that the deviation of the glass ribbon is small and ensuring the normal transportation of the glass ribbon.

[0055] Embodiment 2:

[0056] like Figure 4 As shown, based on the above-mentioned embodiment 1, the roller table fine-tuning device also includes an extension rod 35, and the extension rod 35 is connected to the end of the rocker arm 31 through a pin shaft to extend the rocker arm 31, and the extension rod 35 and the rocker arm 31 are located on the same axis.

[0057] Normally, the longer the length of the pendulum rod 31 is, the farther the plate 32 is from the roller 1, the angle between the plate 32 and the reference wire rope 4 can be magnified, the degree of inclination of the roller 1 can be known more clearly, and it is easier to make precise adjustments. The length of the pendulum rod 31 can be adaptively adjusted according to the requirements for accuracy, as well as whether to increase the length of the extension rod 35 and the extension rod 35. When the pendulum rod 31 is not used for detection, the extension rod 35 can also be used to overlap with the reference wire rope 4 to check the straightness of the pendulum rod 31. If the rod after the pendulum rod 31 and the extension rod 35 are combined always overlaps with the reference wire rope 4, it means that the straightness of the rod is good.

[0058] The extension rod 35 is provided with a plurality of mounting positions for mounting the adjusting rod assembly. The adjusting rod assembly can be adjusted and mounted on the extension rod 35. The end of the adjusting assembly on the extension rod 5 is connected to the flat plate 32. During calibration, the adjusting assembly and the flat plate 32 are connected at only one position, such as Figure 5 One of the positions 1, 2, 3, and 4 can be installed in different positions to check how the calibration is done.

[0059] The basic function of the extension rod 35 is the same as that of the rocker rod 31, and both can be used to check the parallelism of the roller 1. The increased length can also improve the accuracy of the check.

[0060] Embodiment three:

[0061] like Figure 5 As shown, this embodiment provides a method for fine-tuning the roller table of an annealing furnace, using the above-mentioned fine-tuning device for the roller table of an annealing furnace, comprising the following steps:

[0062] S01: Based on the center line of the annealing furnace shell, a reference steel wire rope 4 is arranged on one or both sides of the annealing furnace, so that the reference steel wire rope 4 is parallel to the center line of the annealing furnace shell, and the height of the roller 1 on the transmission side is adjusted according to the original design size. After the adjustment of the transmission side is completed, the height of the roller 1 on the transmission side is used as the adjustment reference of the non-transmission side;

[0063] S02: Connect the extension rod 35 to the end of the swing rod 31 through a pin shaft, so that the extension rod 35 and the swing rod 31 are located on the same axis, and bring the swing rod 31, the extension rod 35 and the reference wire rope 4 close to each other to check the straightness of the swing rod 31. If the rod after the swing rod 31 and the extension rod 35 are combined always coincides with the reference wire rope 4, it means that the straightness of the rod is good. If there is an angle between the two, it means that the swing rod 31 may be bent and should be replaced. After the inspection is completed, the extension rod 35 is disassembled;

[0064] Then, insert the positioning shaft 21 into the positioning hole 11, and rotate the first magnet 22. When the two poles (N or S) of the first magnet 22 are in a horizontal direction, and the N or S pole of the first magnet 22 is facing the second magnet 23, the second magnet 23 is magnetized, and has a strong magnetic field in this direction, which can be used to attract the surface of the shaft head of the roller 1, and fix the device to the roller 1;

[0065] S03: Adjust the adjusting rod assembly to bring the plate 32 and the reference wire rope 4 closer together, and observe whether the plate 32 and the reference wire rope 4 are parallel or overlapped. Figure 6 As shown, after the swing arm part 3 is connected to the roller 1 and rotated 180°, observe whether the flat plate 32 is parallel or overlapped with the reference steel wire rope 4. When the center lines of the flat plate 32 and the roller 1 on both sides are in contact or parallel state, it means that this roller is perpendicular to the center line of the annealing furnace shell. If they are not parallel or overlapped, it is judged that the roller 1 is not parallel, and adjustments are made until the flat plate 32 is parallel or overlapped with the reference steel wire rope; by analogy, the center lines of all rollers 1 are perpendicular to the center line of the shell, ensuring that the center lines of all rollers 1 are parallel. In this way, the deviation of the glass ribbon is small; the adjustment method is to raise it, beat it, etc., until the roller 1 is perpendicular to the center line of the annealing furnace shell.

[0066] S04: By adjusting the rod assembly and installing the flat plate 32 at different installation positions of the swing arm 31, multiple checks are performed to see whether the flat plate 32 and the reference wire rope 4 are parallel or overlapped; the extension rod 35 can also be reconnected to the swing arm 31 for review and verification.

[0067] S05: Adjust all rollers 1 in sequence according to steps S02-S04 until all rollers 1 are parallel.

[0068] The method of this embodiment can set the length of the swing rod 31 according to the accuracy requirement, has strong adaptability, and can perform accurate and fast inspections, thus providing a basis for subsequent adjustments.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
