Description

Technical Field

[0001] The invention belongs to the technical field of cold rolling sinking roller operation, in particular to a cold rolling sinking roller smooth operation device. Background Art

[0002] The cold rolling sinking roller smooth running device is a key equipment of the hot-dip galvanizing unit in the production of cold-rolled strip steel. It is mainly used to support and guide the running direction of the strip steel in the molten zinc liquid to ensure the stable surface quality of the strip steel. Its function is to prevent the strip steel from deflecting or twisting during high-speed operation, while reducing zinc slag adhesion and roller surface wear, thereby extending equipment life and improving production efficiency.

[0003] For example, the publication number is CN119194324B, and the name is "A sinking roller suitable for zinc-aluminum-magnesium alloy", which includes a zinc pot; a roller body; two adjustment plates, which rotate symmetrically and are slidably connected to the two ends of the roller body; a clamping mechanism, which includes two clamping components respectively arranged on both sides of the zinc pot, each clamping component includes two clamping plates, and the two clamping plates are both clamped with the strip steel.

[0004] In the existing technology, when the strip is offset, it will abut one of the adjustment plates, causing the adjustment plate to move along the axis of the roller body. The movement of the adjustment plate drives a group of clamping components away from the adjustment plate to work, so that the two clamps clamp the strip. The strip will drive the two clamps to move synchronously. While following the movement of the strip, the two clamps will move along the width direction of the strip, thereby pulling the strip to move on the roller body and adjusting the position, thereby completing the correction operation. However, because one side of the strip abuts against the sinking roller and the overall height of the two clamps is fixed, when facing strips of different thicknesses, the overall position of the two clamps cannot be adjusted, resulting in the strip not abutting against the sinking roller when the two clamps clamp the strip, affecting the strip transmission.

[0005] To this end, the present invention provides a cold rolling sinking roller smooth operation device. Summary of the Invention

One end of the guide groove is fixedly connected to an electric telescopic rod. The first rack and the second rack both slide in the guide groove.

[0014] Preferably, an anti-tilt assembly is provided in the zinc liquid tank, and the anti-tilt assembly includes a telescopic cylinder, a second limit plate is slidably provided at one end of the telescopic cylinder, and a plurality of second balls are rollingly connected to the bottom of the second limit plate. The telescopic cylinder is moved downward by the rotation of the gear, so that the second balls on the second limit plate abut against the top of the strip, causing the strip to move horizontally and linearly.

[0015] Preferably, the anti-tilt assembly also includes a screw rod, which is fixed at the bottom of the gear and threadedly connected to the telescopic cylinder. Fixed rods are symmetrically fixedly connected to the top of the zinc liquid tank, and sliding cylinders are slidably connected to the two fixed rods.

[0020] 2. The present invention enables the telescopic cylinder to move downward under the guidance of the fixed rod through the rotation of the gear, thereby driving the telescopic cylinder to move downward, thereby driving the second limiting plate to move downward synchronously through the second fixed plate, so that the second ball contacts the top of the strip steel. As the gear continues to rotate, the second limiting plate continues to move downward, so that the strip steel thereunder remains horizontal. Subsequently, as the second fixed plate moves downward, under the guidance of the second sliding rod, the first return spring elastically stretches and the second return spring elastically contracts until the gear stops rotating and the second fixed plate remains stationary, thereby preventing the strip steel from tilting when limited by the first ball steel. At the same time, it can also prevent the strip steel of different thicknesses from tilting, further ensuring the uniform mass distribution of the strip steel after galvanizing, so that the stabilizing device can operate stably.

[0021] 3. The anti-deviation component and anti-tilt component of the present invention can limit the strips of different sizes so that they can maintain linear movement during the galvanizing process. At the same time, the setting of the first ball and the second ball thereon does not affect the normal movement of the strip. When the strip deviates and tilts, the anti-deviation component and the anti-tilt component limit the strip more easily through rolling. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1

[0036] like Figures 1 to 8 As shown, a cold rolling submerged roller smooth operation device according to an embodiment of the present invention includes a zinc liquid tank 1, one end of the zinc liquid tank 1 is fixedly connected to a motor 11, two bearing seats 12 are fixedly connected inside the zinc liquid tank 1, and the two bearing seats 12 are respectively fixed on the two inner walls of the zinc liquid tank 1, and an immersion roller 13 is rotatably connected between the two bearing seats 12;

[0037] An anti-deviation component is provided in the zinc liquid tank 1. The anti-deviation component consists of a guide component and an adaptive clamping component. The guide component includes a first rack 23, and a second rack 25 is slidably provided on one side of the first rack 23. Two groups of adaptive clamping components are provided, which are respectively provided at one end of the first rack 23 and the second rack 25. The adaptive clamping component includes a first limiting plate 29, and a plurality of first balls 211 are rollingly provided on one side of the first limiting plate 29. The first rack 23 and the second rack 25 move toward each other, driving the two first limiting plates 29 to move toward each other, thereby limiting the strip located between the two first limiting plates 29 and keeping it moving in a straight line.

[0038] The two first limit plates 29 are respectively located at both ends of the immersion roller 13. The bottom end of the first limit plate 29 is in the same straight line as the top of the immersion roller 13, so that the first limit plate 29 can abut against one end of the strip steel at the top of the immersion roller 13.

[0039] Specifically, counterweight flanges 14 are provided at both ends of the immersion roller 13, a bearing is provided in the bearing seat 12, and the output end of the zinc liquid tank 1 is fixed to one end of the bearing seat 12;

[0040] In the existing technology, when the strip is offset, it will abut one of the adjustment plates, causing the adjustment plate to move along the axis of the roller body. The movement of the adjustment plate drives a group of clamping components away from the adjustment plate to work, so that the two clamps clamp the strip. The strip will drive the two clamps to move synchronously. While following the movement of the strip, the two clamps will move along the width direction of the strip, thereby pulling the strip to move on the roller body and adjusting the position, thereby completing the correction operation. However, because one side of the strip abuts against the sinking roller and the overall height of the two clamps is fixed, when facing strips of different thicknesses, the overall position of the two clamps cannot be adjusted, resulting in the strip not abutting against the sinking roller when the two clamps clamp the strip, affecting the strip transmission.

[0041] Therefore, the present invention solves this problem by setting up a corresponding structure. When galvanizing the strip, one end of the strip is first pulled so that it partially passes through the immersion roller 13 and contacts its surface. Then, the first rack 23 and the second rack 25 move toward each other, driving the two first limit plates 29 to move toward each other, so that the first ball 211 abuts against both sides of the strip. Then, the motor 11 is started to rotate the immersion roller 13, so that the strip moves in a straight line through the rotation of the immersion roller 13 during the galvanizing process, preventing the strip from deviating and causing the problem of increased wear between the bearings and the shaft head in the existing smooth operation device, thereby ensuring the smooth operation of the immersion roller 13 and the quality of the galvanized strip.

[0042] Example 2

[0043] like Figures 2 to 8 As shown, compared with Example 1, another embodiment of the present invention is:

[0044] like Figures 3 to 6 As shown, the guide component of this embodiment also includes a guide groove 21, which is opened at the top of the zinc liquid tank 1. One end of the guide groove 21 is fixedly connected to the electric telescopic rod 22. The first rack 23 and the second rack 25 both slide in the guide groove 21. The middle of the guide groove 21 is rotatably connected to a gear 24. The output end of the electric telescopic rod 22 is fixedly connected to one end of the first rack 23. The gear 24 is located between the first rack 23 and the second rack 25. The gear 24 is meshed with the first rack 23 and the second rack 25.

[0045] Both sets of adaptive clamping components include a connecting block 26, which is respectively fixed to the first rack 23 and one end of the bottom of the first rack 23, and a first fixed plate 27 is fixedly connected to the bottom of the connecting block 26. A first slide bar 28 is slidably connected to the first fixed plate 27, and one end of the first slide bar 28 is fixed to the first limiting plate 29. A compression spring 210 is fixedly connected between one end of the first slide bar 28 and one side of the first fixed plate 27. There are multiple first slide bars 28, and one end of multiple first slide bars 28 is fixed on a first limiting plate 29. The compression spring 210 is located on the side of the first fixed plate 27 away from the first slide bar 28.

[0046] Specifically, the first rack 23 and the second rack 25 are staggered and symmetrically arranged. Initially, the electric telescopic rod 22 is in an extended state, and the compression spring 210 is not deformed;

[0047] When the strip steel portion passes through the immersion roller 13 and contacts its surface, the electric telescopic rod 22 is started to retract its output end. The contraction of the output end of the electric telescopic rod 22 drives the first rack 23 to move, and the transmission of the gear 24 drives the second rack 25 to move, so that the first rack 23 and the second rack 25 move toward each other, driving the first fixed plate 27 thereon to move toward the direction close to the middle of the gear 24. In this process, under the limiting action of the first slide bar 28 and the compression spring 210, the movement of the first fixed plate 27 drives the first limiting plate 23 to move toward the middle of the gear 24. The plates 29 move synchronously until the compression spring 210 contacts one side of the strip, so that both sides of the strip are limited by the contact of the compression springs 210 on the two first limiting plates 29. At this time, the first limiting plates 29 no longer move. As the first fixed plate 27 continues to move, the first fixed plate 27 moves toward the direction close to the first limiting plates 29. The compression spring 210 is in an elastically stretched state, preventing the strips of different sizes from deviating until the electric telescopic rod 22 is fully retracted. At this time, the first rack 23 and the second rack 25 remain stationary.

[0048] The present invention drives the first rack 23 and the second rack 25 to move relative to each other through the contraction of the electric telescopic rod 22, and the first rack 23 and the second rack 25 move relative to each other, respectively driving the first fixed plate 27 thereunder to move, so that the two first fixed plates 27 move relative to each other, thereby driving the compression springs 210 on the first limiting plate 29 to abut against both sides of the strip and limit it, so that when the immersion roller 13 drives the strip to move, the strip can move normally through the rolling of the compression springs 210, and through the arrangement of multiple first sliding bars 28 and compression springs 210, the first limiting plate 29 can only move linearly, so that when the immersion roller 13 vibrates, the strip will not deviate. At the same time, the compression springs 210 on the first limiting plate 29 can limit strips of different sizes, ensuring the uniform distribution of the overall mass of the strip after galvanizing, and preventing the uneven load borne by the sinking roller when continuing to run due to uneven distribution of the overall mass of the strip, thereby increasing the wear between the bearing and the shaft head, and then causing the problem of unstable operation of the sinking roller, so that the stable operation of the stabilizing device is also guaranteed. The quality of the galvanized strip is

[0049] like Figure 4 、 Figure 7 and Figure 8 As shown, in this embodiment, the zinc liquid tank 1 is provided with an anti-tilt assembly, which includes a telescopic cylinder 32. A second limit plate 38 is slidably provided at one end of the telescopic cylinder 32. A plurality of second balls 311 are rollingly connected to the bottom of the second limit plate 38. The rotation of the gear 24 causes the telescopic cylinder 32 to move downward, causing the second balls 311 on the second limit plate 38 to abut against the top of the strip, thereby causing the strip to move horizontally and linearly.

[0050] The anti-tilt assembly also includes a screw rod 31, which is fixed to the bottom of the gear 24 and is threadedly connected to a telescopic cylinder 32. Fixed rods 33 are symmetrically fixedly connected to the top of the zinc liquid tank 1. Slide cylinders 34 are slidably connected to the two fixed rods 33. Connecting plates 35 are fixedly connected to the surfaces of the two slide cylinders 34 and the telescopic cylinder 32.

[0051] The bottom of the telescopic cylinder 32 is fixedly connected to the second fixed plate 36, and the second sliding rod 37 is symmetrically slidably connected to the second fixed plate 36. The bottom ends of the two second sliding rods 37 are fixed to the second limit plate 38. A first return spring 39 is fixedly connected between one end of each second sliding rod 37 and the top of the second fixed plate 36. A second return spring 310 is fixedly arranged between the bottom of each second sliding rod 37 and the bottom of the second fixed plate 36. The bottom ends of the two second return springs 310 are fixed to the bottom of the second limit plate 38. The bottom of the second limit plate 38 is perpendicular to the top of the immersion roller 13. The two sliding cylinders 34 are respectively arranged above the two ends of the second fixed plate 36, and the two second sliding rods 37 are respectively close to both sides of the second fixed plate 36.

[0052] Specifically, since the screw rod 31 is threadedly connected to the telescopic cylinder 32, the telescopic cylinder 32 will rotate synchronously with the screw rod 31. Since the fixed rod 33 is fixed to the zinc liquid tank 1, the slide 34 is sleeved on the surface of the fixed rod 33. The telescopic cylinder 32 and the slide 34 are connected by the connecting plate 35, so that the slide 34 and the telescopic cylinder 32 move synchronously. At the same time, the telescopic cylinder 32 is limited at this time. When the screw rod 31 rotates, the telescopic cylinder 32 can only move vertically and linearly.

[0053] The telescopic cylinder 32 is longer than the slide 34. When the top of the slide 34 abuts against the bottom of the fixed rod 33, the slide 34 is extended to the farthest distance. At this time, the telescopic cylinder 32 will not separate from the screw rod 31.

[0054] Initially, the slide 34 is in a retracted state, the second return spring 310 has a relatively large elastic force, the first return spring 39 and the second return spring 310 are not deformed, and the second limiting plate 38 remains relatively fixed to the second fixing plate 36 under the guidance of the second slide rod 37 and the action of the first return spring 39 and the second return spring 310;

[0055] During the transmission of gear 24, the rotation of gear 24 causes the telescopic cylinder 32 to move downward under the guidance of the fixed rod 33, thereby driving the telescopic cylinder 32 to move downward, thereby driving the second limit plate 38 to move downward synchronously through the second fixed plate 36, so that the second ball 311 abuts against the top of the strip steel. As the gear 24 continues to rotate, the second limit plate 38 continues to move downward, keeping the strip steel thereunder horizontal. Subsequently, as the second fixed plate 36 moves downward, under the guidance of the second slide bar 37, the first return spring 39 elastically stretches and the second return spring 310 elastically contracts until the gear 24 stops rotating and the second fixed plate 36 stops moving, thereby preventing the strip steel from tilting when it is limited by the first ball 211. At the same time, it can also prevent the strip steel from tilting when it is limited by the first ball 211, and further ensure that the mass distribution of the strip steel after galvanizing is uniform, so that the stabilizing device can operate stably.

[0056] The anti-deviation component and anti-tilt component of the present invention can limit strip steels of different sizes so that they can maintain linear movement during the galvanizing process. At the same time, the arrangement of the first ball 211 and the second ball 311 thereon does not affect the normal movement of the strip steel. When the strip steel deviates and tilts, the strip steel can be more easily limited by rolling under the limiting action of the anti-deviation component and the anti-tilt component.

[0057] Working principle:

[0058] When galvanizing the strip, one end of the strip is first pulled so that it partially passes through the immersion roller 13 and contacts its surface, and then the electric telescopic rod 22 is started to retract its output end. The contraction of the output end of the electric telescopic rod 22 drives the first rack 23 to move, and the second rack 25 is driven to move through the transmission of the gear 24, so that the first rack 23 and the second rack 25 move toward each other, driving the first fixed plate 27 thereon to move toward the direction close to the middle of the gear 24. In this process, under the limiting action of the first slide bar 28 and the compression spring 210, the first fixed plate 27 moves. The movement will drive the first limiting plate 29 to move synchronously until the compression spring 210 abuts against one side of the strip, so that both sides of the strip are limited by the abutment of the compression springs 210 on the two first limiting plates 29. At this time, the first limiting plate 29 no longer moves. As the first fixed plate 27 continues to move, the first fixed plate 27 moves toward the direction close to the first limiting plate 29. The compression spring 210 is in an elastically stretched state, preventing the deviation of strips of different sizes until the electric telescopic rod 22 is fully retracted. At this time, the first rack 23 and the second rack 25 remain stationary.

[0059] During the transmission process of the gear 24, the rotation of the gear 24 causes the telescopic cylinder 32 to move downward under the guidance of the fixed rod 33, thereby driving the telescopic cylinder 32 to move downward, thereby driving the second limiting plate 38 to move downward synchronously through the second fixed plate 36, so that the second ball 311 abuts against the top of the strip steel. As the gear 24 continues to rotate, the second limiting plate 38 continues to move downward, keeping the strip steel thereunder horizontal. Subsequently, as the second fixed plate 36 moves downward, under the guidance of the second slide bar 37, the first return spring 39 elastically stretches and the second return spring 310 elastically contracts, thereby preventing the strip steels of different thicknesses from tilting, until the gear 24 stops rotating and the second fixed plate 36 stops moving.

[0060] Then, the motor 11 is started to rotate the immersion roller 13, so that the strip moves linearly through the rotation of the immersion roller 13 during the galvanizing process.
