Description

Technical Field

[0001] The utility model relates to a furnace nose device, in particular to a stabilizing roller device used for the furnace nose. Background Art

[0002] In the production of hot-dip galvanizing, the steel strip is conveyed into the furnace nose by the tension roller located above, and after passing through the furnace nose, it is guided to the sinking roller located in the zinc pot below. Due to the long distance between the tension roller and the sinking roller, the steel strip is prone to vibrate in the furnace nose, affecting the surface quality of the steel strip. Therefore, a stabilizing roller is set inside the furnace nose to prevent the steel strip from vibrating.

[0003] In the prior art, the position of the stabilizing roller is fixed, and the conveyed steel strip is attached to the surface of the stabilizing roller and forms a fixed wrap angle with the stabilizing roller. The driving motor drives the stabilizing roller to rotate through the belt, and the rotation speed of the stabilizing roller is kept consistent with the moving speed of the steel strip through electrical control. In the actual operation process, in order to adjust the tension on the steel strip, it is necessary to adjust the wrap angle formed by the steel strip and the stabilizing roller. The prior art is to adjust the wrap angle formed by the steel strip and the stabilizing roller by controlling the swing of the furnace nose, but this will cause the steel strip to deviate from the center of the furnace nose, so that when the slag removal furnace nose tip is used later, the steel strip is easily scratched due to the narrow channel of the slag removal furnace nose tip, which affects the quality.

[0004] In addition, since the furnace nose can swing, the stability of the furnace nose is not good, and the stabilizing roller is driven by a belt, which will vibrate during the driving process, so the furnace nose will vibrate slightly, and this slight vibration will cause the distance between the axis of the drive motor output shaft and the axis of the stabilizing roller to fluctuate, thereby causing the belt to slip, resulting in the actual steel belt moving speed being inconsistent with the rotation speed of the stabilizing roller. Once the speed of the steel belt and the stabilizing roller is inconsistent, the two will produce friction, resulting in scratches on the surface of the steel belt, affecting the quality of the steel belt.

[0024] refer to Figures 1 to 4 According to a preferred embodiment of the utility model, a stabilizing roller device for a furnace nose will be described in detail below. The stabilizing roller device for a furnace nose is used to adjust the tension of the steel strip in the furnace nose. Figure 1 As shown, the furnace nose 90 has a steel strip passage 901 and two roller holes 902, and the furnace nose 90 is arranged obliquely and the inclination angle is consistent with the inclination angle of the steel strip conveyed to the zinc pot, and the steel strip passes obliquely through the steel strip passage 901 from the top of the furnace nose 90 and enters the zinc pot below. The two roller holes 902 are formed on two opposite sides of the furnace nose 90 and are located on a horizontal plane at the same height, and the two roller holes 902 are connected to the steel strip passage 901.

[0025] The stabilizing roller device for a furnace nose comprises a stabilizing component 10 and an adjusting component 20 .

[0026] like Figure 1 As shown, the stabilizing assembly 10 includes a stabilizing roller 11, a first driving member 12 and at least one bearing seat 13, wherein the size of the stabilizing roller 11 is smaller than the size of the roller hole 902, the stabilizing roller 11 can rotatably pass through the two roller holes 902, and the two ends of the stabilizing roller 11 extend out of the two roller holes 902 respectively and at least one end is installed with the bearing seat 13. The stabilizing roller 11 is drivably connected to the first driving member 12 so as to be driven to rotate by the first driving member 12 in the steel strip channel 901. The stabilizing roller 11 is located outside the steel strip and keeps in contact with the steel strip, and the steel strip can be driven by the rotating stabilizing roller 11 to guide the zinc pot.

[0027] As an example, the first driving member 12 is implemented as a driving motor.

[0028] like Figures 1 to 4 As shown, the adjustment assembly 20 includes at least one bracket 21 and at least one second driving member 22, wherein one of the brackets 21 is installed on the side of the furnace nose 90 and close to the bearing seat 13. The second driving member 22 is installed on the bracket 21, and the second driving member 22 is drivably connected to the bearing seat 13. The second driving member 22 can drive the bearing seat 13 to move so as to drive the stabilizing roller 11 connected to the bearing seat 13 to move in the roller hole 902. In the process of the stabilizing roller 11 being driven by the bearing seat 13 to move, the first driving member 12 can always output power to the stabilizing roller 11.

[0029] In this way, by adjusting the position of the stabilizing roller 11, the wrap angle between the stabilizing roller 11 and the steel strip will change, thereby changing the tension of the steel strip and preventing the steel strip from shaking. In addition, by adjusting the stability of the stabilizing roller 11 to achieve the adjustment of the wrap angle, compared with the prior art, the steel strip is still in the center of the steel strip channel 901, avoiding being scratched by the slag discharge furnace nose in subsequent operations.

[0030] Preferably, the direction in which the stabilizing roller 11 is driven by the bearing seat 13 to move is set to be perpendicular to the surface of the steel belt, so that the stabilizing roller 11 can move in a direction perpendicular to the surface of the steel belt to quickly adjust the tension of the steel belt.

[0031] By way of example, the second drive member 22 is implemented as a hydraulic cylinder.

[0032] Preferably, the number of the second driving members 22 and the number of the bearing seats 13 are both implemented as two, and each of the second driving members 22 is drivably connected to one of the bearing seats 13, so that the stabilizing roller 11 is driven to move simultaneously by the two bearing seats 13, thereby ensuring that the overall moving distance of the stabilizing roller 11 remains consistent, thereby avoiding inconsistent moving distances at both ends of the stabilizing roller 11, resulting in excessive contact between the surface of the stabilizing roller 11 and the surface of the steel belt, and causing friction between the steel belt and the surface of the stabilizing roller 11.

[0033] More preferably, the second driving member 22 is implemented as a driving motor. The adjustment assembly 20 also includes at least one belted member 23, each of which includes a rotating shaft 231, a screw 232 and a stop tube 233, wherein the rotating shaft 231 is drivably connected to the second driving member 22, the rotating shaft 231 of each belted member 23 passes through the stop tube 233 and can rotate in the stop tube 233, the screw 232 passes through the stop tube 233 and can move axially along the stop tube 233, and the rotating shaft 231 and the screw 232 are threadedly connected in the stop tube 233, so that when the rotating shaft 231 is driven to rotate by the second driving member 22, the screw 232 is driven to move by the rotating rotating shaft 231. One end of each screw 232 is connected to the bearing seat 13, and the moving direction of the screw 232 is set to be perpendicular to the surface of the steel belt. When the screw 232 moves, the bearing seat 13 and the stabilizing roller 11 as a whole can be driven by the screw 232 to move in a direction perpendicular to the surface of the steel belt.

[0034] Preferably, two of the conveyed members 23 are provided, and the number of the second driving members 22 is implemented as one, the rotating shafts 231 of the two conveyed members 23 are integrally connected, and the screws 232 of the two conveyed members 23 are respectively threadedly connected to the two rotating shafts 231, so that one second driving member 22 can drive the two screws 232 to move.

[0035] Preferably, the adjustment assembly 20 further includes at least one distance detection member 24 , and the distance detection member 24 can detect the moving distance of the stabilizing roller 11 , so as to facilitate accurate adjustment of the position of the stabilizing roller 11 .

[0036] In one embodiment, the distance detection element 24 is implemented as a distance sensor.

[0037] In another embodiment, Figure 2 and Figure 4 As shown, the distance detection member 24 includes a moving block 241 and a scale member 242. The moving block 241 is installed on the bearing seat 13 and moves with the bearing seat 13. The scale member 242 is installed on the bracket 21 and is located below the moving block 241. The scale member 242 has scale lines. The bottom of the moving block 241 has a pointer 2411, and the pointer 2411 is aligned with the scale line. When the moving block 241 is driven to move, the pointer 2411 will move on the scale line, so that the user can understand the specific moving distance of the stabilizing roller 11, which is convenient for the user to accurately adjust the position of the stabilizing roller 11.

[0038] Preferably, if Figures 1 to 4 As shown, the adjustment assembly 20 further includes at least one reducer 25, which is drivably connected to the second driving member 22, and the reducer 25 is drivably connected to the rotating shaft 231. The rotating shaft 231 is decelerated by the reducer 25, so that the moving distance of the stabilizing roller 11 is more accurate, which is convenient for the user to accurately adjust the position of the stabilizing roller 11.

[0039] Preferably, the first driving member 12 includes a driving member 121 and a connecting member 122, one end of the connecting member 122 is connected to the stabilizing roller 11, and the other end is connected to the driving member 121, so that the driving member 121 drives the stabilizing roller 11 to rotate through the connecting member 122. In this way, the driving member 121 does not need a belt to drive the stabilizing roller 11, so as to avoid the steel belt being affected by the shaking belt and generating friction with the stabilizing roller 11, and when the bearing seat 13 moves, the driving member 121 can still drive the stabilizing roller 11.

[0040] By way of example, the connecting element 122 is implemented as a coupling.
