Description

Technical Field

[0001] The present application relates to the technical field of glass cover plate production, and in particular to a transition roller sway correction device. Background Art

[0002] The float glass transition roller is a key device between the tin bath equipment and the annealing furnace. It is the continuation of the end of the tin bath equipment. Its main function is to introduce the glass ribbon of about 600 degrees Celsius drawn from the tin bath into the annealing furnace through the "U"-shaped groove through the transition roller. Although the "U"-shaped groove is made of high-temperature resistant steel, it is in high temperature for a long time. In addition, the length of the "U"-shaped groove reaches 6 meters, so it will produce a certain amount of deformation. There are two shapes of "U"-shaped groove after high-temperature deformation. The first is that the middle is arched upward. This deformation has little effect on the replacement of transition rollers; the other is that it is deformed into an "S" shape in the horizontal direction. At the same time, there is a height difference between the two shoulders of the "U"-shaped groove. This deformation has a greater impact on the replacement of transition rollers, and will cause the old roller pulled out and the new roller pushed in to swing left and right, or tilt to the side with the lower shoulder of the "U"-shaped groove. The transition roller is likely to touch the wall of the slag box hole, and the roller surface is damaged, resulting in the scrapping of the transition roller, causing huge losses.

[0003] The existing transition roller replacement device (for example, application number: 201820619705.5, name: a transition roller table device capable of online roller replacement) can realize the replacement of transition rollers without stopping production. However, there is no good solution to the problem of transition roller swing during the replacement process. Utility Model Content

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0026] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0027] like Figure 1 and Figure 4As shown, the embodiment relates to a transition roller sway correction device, including: a roller changing assembly 10 and a sway correction assembly 20. The roller changing assembly 10 includes a first roller changing structure 11, a second roller changing structure 12 and a support structure 13, and the first roller changing structure 11 and the second roller changing structure 12 are both arranged on the support structure 13. The sway correction assembly 20 includes a support frame structure 21, a sway correction structure 22 and a top structure 23, the support frame structure 21 is connected to the support structure 13, the sway correction structure 22 is connected to the support frame structure 21, and the sway correction structure 22 cooperates with the top structure 23.

[0028] The technical solution of this embodiment is applied, and the transition roller sway correction device includes: a roller changing assembly 10 and a sway correction assembly 20. The roller changing assembly 10 includes a first roller changing structure 11, a second roller changing structure 12 and a support structure 13. The first roller changing structure 11 and the second roller changing structure 12 are both arranged on the support structure 13 and supported by the support structure 13, so that when the first roller changing structure 11 and the second roller changing structure 12 replace the transition roller 100, it is not easy to produce a height difference so that the surface of the transition roller 100 and the slag box are scratched. The first roller changing structure 11 and the second roller changing structure 12 are connected to the transition roller 100 respectively, and the transition roller 100 is driven to move by applying a force to the first roller changing structure 11 and the second roller changing structure 12 to achieve the replacement of the transition roller 100. The swing correction assembly 20 includes a support frame structure 21, a swing correction structure 22 and a support structure 23. The support frame structure 21 is connected to the support structure 13, and the swing correction structure 22 is connected to the support frame structure 21. The swing correction structure 22 cooperates with the support structure 23. The swing correction structure 22 is adjusted to the correct position by the support structure 23. The swing correction structure 22 faces the direction close to the transition roller 100. When the transition roller 100 swings during the replacement process, the swing correction structure 22 can be supported against the transition roller 100, so that the transition roller 100 will not be scratched against the slag box. The technical solution of the present application effectively solves the problem in the prior art that the swing of the transition roller 100 cannot be effectively corrected when the transition roller 100 is replaced.

[0029] like Figure 2As shown, in some embodiments, the sway correction structure 22 includes a rotating shaft 221, a roller body 222, a buffer layer 223 and a high temperature resistant layer 224. The roller body 222 is arranged on the circumferential outer side of the rotating shaft 221, and a clamping groove is arranged on the circumferential outer side of the roller body 222. The buffer layer 223 is located on the circumferential outer side of the roller body 222 and has a plurality of protrusions matched with the clamping grooves. The high temperature resistant layer 224 is arranged on the circumferential outer side of the buffer layer 223. The rotating shaft 221 is limited by a cotter pin, and the clamping groove and the protrusion cooperate so that the buffer layer 223 can be closely attached to the roller body 222. The buffer layer 223 is arranged on the circumferential outer side of the buffer layer. Since the surface temperature of the old transition roller 100 is about 500 degrees Celsius, the high temperature resistant layer 224 can effectively prevent the buffer layer 223 from being scalded. When installing a new transition roller 100, the high temperature resistant layer 224 can be removed. Usually, the buffer layer 223 can be a rubber buffer layer, and the high temperature resistant layer 224 can be a graphite high temperature resistant layer.

[0030] It should be noted that the thickness of the buffer layer 223 is between 4.7 mm and 5.3 mm. When the buffer layer 223 is against the transition roller 100 for swing correction, the buffer layer will be deformed, and the thickness after deformation is between 2.7 mm and 4.3 mm.

[0031] It should also be noted that when the transition roller 100 is replaced (pushing out the old transition roller 100 and pushing in the new transition roller 100), the high temperature resistant layer 224, the buffer layer 223 and the roller body 222 can rotate around the rotating axis 221 under the action of the transition roller 100 and are in linear contact with the surface of the transition roller 100, which can reduce the impact of the correction structure 22 on the transition roller 100.

[0032] like Figure 2As shown, in some embodiments, the correction structure 22 also includes a support frame 225, a first bearing 226, a second bearing 227, a first positioning sleeve 228 and a second positioning sleeve 229. The rotating shaft 221 is passed through the support frame 225 and is limited by a cotter pin. The first bearing 226 and the second bearing 227 are both installed on the circumferential outer side of the rotating shaft 221, which can reduce friction. The first positioning sleeve 228 and the second positioning sleeve 229 are both installed on the circumferential outer side of the rotating shaft 221 to play a positioning role. The first positioning sleeve 228 is located between the support frame 225 and the first bearing 226, and the second positioning sleeve 229 is located between the support frame 225 and the second bearing 227. The roller body 222 has a limiting portion, which is located between the first bearing 226 and the second bearing 227 and abuts against the first bearing 226 and the second bearing 227. The limiting portion (the raised portion of the roller body 222 close to the rotating shaft 221) abuts against the first bearing 226 and the second bearing 227, the first bearing 226 and the second bearing 227 abut against the first positioning sleeve 228 and the second positioning sleeve 229 respectively, and the first positioning sleeve 228 and the second positioning sleeve 229 abut against the support frame 225 respectively, which prevents the roller body 222, the buffer layer 223 and the high temperature resistant layer 224 from moving axially along the rotating shaft 221.

[0033] like Figure 3 As shown, in some embodiments, the support frame structure 21 includes a support upright plate 211, a support platform 212 and a connecting seat 213. The support upright plate 211 and the connecting seat 213 are both arranged on the support platform 212. The support frame 225 is swingably arranged on the connecting seat 213. The distance between the correction structure 22 and the transition roller 100 can be adjusted by the swing of the support frame 225. The position of the correction structure 22 is based on the transition roller 100 not colliding with the slag box. On this basis, the swing degree of the correction structure 22 is adjusted according to the swing range of the transition roller 100.

[0034] like Figure 1 As shown, in some embodiments, the swing correction structure 22 can swing away from the transition roller 100, and the angle between the center line of the rotating shaft 221 and the supporting platform 212 is less than or equal to 90°. When the swing range of the transition roller 100 is small during the replacement process, the transition roller 100 will not abut against the swing correction structure 22, and the transition roller 100 will not collide with the slag box, and the angle between the center line of the rotating shaft 221 and the supporting platform 212 is less than or equal to 90°, which makes the swing correction structure 22 always contact with the abutting structure 23 under the action of gravity, and the swing correction structure 22 will not impact the surface of the transition roller 100.

[0035] like Figure 3As shown, in some embodiments, the support upright plate 211 has a matching hole, the matching hole has an internal thread, the abutting structure 23 includes a abutting screw 231 and an operating handle 232, the operating handle 232 is fixedly connected to the abutting screw 231, the abutting screw 231 has an external thread, the abutting screw 231 is meshed with the matching hole, and the abutting screw 231 is in contact with the support frame 225. By screwing the operating handle 232, the movement of the abutting screw 231 can be achieved, the abutting screw 231 is in contact with the support frame 225, and with the movement of the abutting screw 231, the swing of the swing correction structure 22 can be adjusted.

[0036] like Figure 4 As shown, in some embodiments, the first roller changing structure 11 includes a first bearing seat 111 and a moving roller 112, and the first bearing seat 111 is arranged on the moving roller 112. The first end of the transition roller 100 is fixed to the first bearing seat 111 by a locking nut and a shoulder (or a top screw) to limit the axial movement of the transition roller 100.

[0037] like Figure 4 As shown, in some embodiments, the second roller changing structure 12 includes a second bearing seat 121 and a roller pulling trolley 122, and the second bearing seat 121 is arranged on the roller pulling trolley 122. The second end of the transition roller 100 is fixed to the second bearing seat 121 by a locking nut and a shaft shoulder (or a top screw), and the second bearing seat 121 is arranged on the roller pulling trolley 122. By pulling the roller pulling trolley 122, the second bearing seat 121 is driven to move, and then the transition roller 100, the first bearing seat 111 and the moving roller 112 are driven to move, so as to realize the replacement of the transition roller 100.

[0038] like Figure 1 and Figure 4 As shown, in some embodiments, the support structure 13 includes a first roller groove 131, a second roller groove 132 and a moving platform 133. The first roller groove 131, the second roller groove 132 and the third roller groove 101 are connected to form a roller changing channel 102. The second roller groove 132 and the roller pulling trolley 122 are movably arranged on the moving platform 133. The moving roller 112 can move on the roller changing channel 102. When replacing the old transition roller 100, the second bearing seat 121 is driven to move by pulling the roller pulling trolley 122, and then the transition roller 100 is driven to move gradually. With the movement of the transition roller 100, the moving roller 112 gradually moves from the first roller groove 131 to the third roller groove 101 and then to the second roller groove 132. The first bearing seat 111 arranged on the moving roller 112 moves together with the moving roller 112. The first bearing seat 111 and the transition roller 100 are fixed by a locking nut and a shaft shoulder, so that the transition roller 100 is gradually pushed out to achieve the purpose of replacement. When replacing a new transition roller 100, the pushing direction is different, and the rest is the same as the old transition roller 100, which will not be described in detail here.

[0039] It should be noted that the second roller groove 132 is movably placed on the mobile platform 133 through rollers, so as to be aligned with the third roller groove 101. A brake structure is provided on the roller. After the second roller groove 132 is aligned with the third roller groove 101, the rotation of the roller is limited by the brake structure to prevent the movement of the second roller groove 132. The brake structure on the roller is well known to those skilled in the art and will not be described in detail here. It is also possible to place a stop block on the mobile platform 133 to limit the second roller groove 132 after the second roller groove 132 is aligned with the third roller groove 101 (that is, after the position of the second roller groove 132 is determined). The stop block is arranged along the moving direction of the second roller groove 132 and stops against the second roller groove 132 to prevent the second roller groove 132 from moving.

[0040] like Figure 4 As shown, in some embodiments, the sway correction assembly 20 has multiple groups, and the sway correction assembly 20 is arranged on both sides of the mobile platform 133. The position adjustment of the sway correction assembly 20 can be achieved by pushing the mobile platform 133, and multiple sway correction assemblies 20 can limit the horizontal swing of the transition roller 100. The sway correction assembly 20 is located between the first roller changing structure 11 and the second roller changing structure 12. As the old transition roller 100 is pushed out or the new transition roller 100 is pushed in, the sway correction assembly 20 can perform the sway correction function throughout the process of replacing the transition roller 100, which can not only prevent the transition roller 100 from being scrapped due to scratches, but also greatly reduce the time required to replace the transition roller 100.

[0041] It should be noted that a plug-in plate seat is fixedly connected to both sides of the mobile platform 133, and the support frame structure 21 also includes a plug-in plate, which is fixedly connected to the support platform 212. The plug-in plate can be inserted into the plug-in plate seat. At this time, the plug-in plate seat can limit the plug-in plate, thereby limiting the support platform 212. At this time, the sway correction component 20 can be firmly installed on both sides of the mobile platform 133, which is convenient for correcting the sway of the transition roller 100 and also convenient for disassembly and maintenance of the sway correction component 20. The sway correction component 20 can also be welded on both sides of the mobile platform 133, and both can achieve the sway correction of the transition roller 100.

[0042] From the above, it can be known that the transition roller correction device mainly includes a plug-in plate seat, a fixed bracket (support frame structure 21), a T-type adjustment screw (top structure 23), a movable roller frame (support frame 225) and a heat-resistant buffer roller (correction structure 22) and corresponding accessories. The socket seat is symmetrically welded on both sides of the end of the roller-changing trolley close to the slag box. When in use, the lower plug-in plate of the fixed bracket is directly inserted into the plug-in plate seat, and can also be pulled out when not in use. The T-type adjustment screw is installed in the middle of the fixed bracket. The movable roller frame is installed on the lower ear seat of the fixed bracket through a rotating shaft, and the cotter pin limits the withdrawal of the rotating shaft. The heat-resistant buffer roller is composed of a roller body, a bearing, an elastic retaining ring and a surface graphite paper (wrapped), and is installed on the movable roller frame through a central shaft and a positioning sleeve and rotates freely. The cotter pin limits the upward movement of the central shaft. When replacing the transition roller, move the first "U"-shaped groove (first roller groove 131) toward the slag box until it is seamlessly connected with the "U"-shaped groove (third roller groove 101) of the slag box, and the second "U"-shaped groove (second roller groove 132) is also seamlessly connected and fixed with the other end of the "U"-shaped groove of the slag box. The three sections of the "U"-shaped groove are tightly connected together to form an integral slideway (roller changing channel 102). One end of the transition roller 100 is fixed to the hand-pulled sliding platform (roller pulling trolley 122) through the second bearing seat 121, and the other end is fixed to the movable roller 112 through the first bearing seat 111. The movable roller 112 is placed in the "U"-shaped groove slideway. Pulling (pushing) the hand-pulled sliding platform can drive the movable roller 112 at the other end to pass through the slag box to pull out the old roller or push in the new roller. Before changing the rollers, rotate the T-shaped adjusting screws on both sides clockwise respectively to push the movable roller frame and the heat-resistant buffer roller assembly on the corresponding side to rotate around the lower rotating shaft until the heat-resistant buffer roller and the transition roller 100 are in contact with the surface. Since one end of the old roller being pulled out or the new roller being pushed in is fixed on the hand-pull sliding platform and the movable gap is small, the T-shaped adjusting screw can limit the transition roller 100 from sliding in the slag box. It is affected by the high-temperature deformation of the "U"-shaped groove installed on the base of the slag box and swings left and right, so that the old roller can be pulled out smoothly or the new roller can be pushed in. The heat-resistant buffer roller is composed of a bearing, a steel roller body, a rubber buffer layer and a wrapped surface graphite paper. The function of the rubber buffer layer is to avoid damaging the roller surface of the transition roller 100 due to excessive pressure when limiting the swing of the transition roller 100, and to buffer the pressure of the transition roller 100 on the surface graphite paper. The surface graphite paper is a high-temperature resistant material. Its function is to prevent the rubber buffer layer from being burned by the excessive surface temperature of the old roller (about 500°C) when the old roller is pulled out. When installing a new roller, the roller surface temperature is at room temperature, and the wrapped surface graphite paper can be removed at this time.
