Description

Technical Field

[0001] The invention belongs to the technical field of sinking rollers, in particular to a sinking roller with the function of reducing strip deviation. Background Art

[0002] The sinking roller is a key equipment used in the cleaning section of the cold rolling continuous production line or hot-dip galvanizing line in the metallurgical industry. It is often in liquids such as cleaning liquid or zinc liquid. The direction of the strip changes when passing through the sinking roller.

[0003] In the existing technology, the strip needs to be cleaned with alkaline solution because there is a lot of residual oil and iron on the surface of the raw material. Therefore, the strip passes through the turning roller at one end of the cleaning tank and then goes down to the sinking roller to place the strip in the alkaline solution. Then, it goes up through the turning roller on the other side and out of the cleaning tank. At the same time, the correction devices on both sides of the strip are started to correct the deviation of the strip during the cleaning process in the cleaning tank.

[0004] The existing technology still has some shortcomings in actual use. During long-term use, due to the strong corrosiveness of alkali solution, the two ends of the sinking roller are closer to the cleaning tank wall. The alkali solution flow is greatly disturbed here, which easily forms local eddies or stagnant areas, resulting in relatively higher alkali solution concentration and slower renewal speed at the two ends, aggravating chemical corrosion. Corrosion pits first occur on the metal surface, and then the repeated friction of the strip accelerates wear. At the same time, during the transmission of the strip, even with an anti-deviation design, it will still produce slight lateral displacement due to factors such as tension fluctuations and speed changes. The two ends become high-frequency areas of contact and friction between the strip edges, and mechanical wear is more concentrated, making the wear degree of the two ends of the sinking roller significantly higher than that in the middle. As a result, the diameter of the two ends of the sinking roller becomes smaller and the middle part is relatively higher. The middle part of the strip will be subjected to greater support and friction due to the convex roller surface, while the support force at the two ends is insufficient, resulting in unbalanced lateral force on the strip. The strip slides to one side due to the greater friction in the middle, causing deviation, which requires continuous correction of the conveyed strip, thereby affecting the strip cleaning rate.

[0005] To this end, the present invention provides a sinking roller with the function of reducing strip deviation. Summary of the Invention

[0019] 1.

Under the guidance of the guide rod, the lower pressure plate drives the contact 2 to move downward and elastically compress the support spring 1.

[0020] 2. The present invention drives the guide rod to move by the movement of the fixed ring plate, so that the shorter end of the arc plate is close to the roller surface of the roller body, and the gear rod is rotated by the movement of the guide rod, so that the rotating sleeve rotates and drives multiple movable plates to move, so that the middle part pushes the arc plate to converge close to the middle of the roller body until the arc plate is resisted by the end of the roller surface of the roller body. Then the guide rod moves into the linear groove of the gear rod, so that the shorter end part of the arc plate is inserted between the strip steel and the roller surface of the roller end, so that after the strip steel passes through the end of the roller surface of the roller body, it can contact the arc plate, increase its force area, and increase the friction force at both ends of the strip steel, thereby preventing the strip steel from sliding to one side due to the large friction force in the middle during transmission, thereby causing the problem of offset.

[0021] 3.

[0041] 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.

[0042] Example 1

[0043] like Figures 1 to 14As shown, a submerged roller with the function of reducing strip deviation in an embodiment of the present invention includes a cleaning tank 1, wherein a steering rod 11 is symmetrically arranged in the cleaning tank 1, and a roller body 12 is rotatably arranged between the two steering rods 11;

[0044] The cleaning tank 1 is provided with a detection component, which includes a fixed block 21, an inverted T-shaped slider 23 is slidably provided in the middle of the fixed block 21, and a movable plate 25 is fixedly connected to the top of the inverted T-shaped slider 23. An inverted T-shaped slider 24 is slidably provided at one end of the fixed block 21. The bottoms of the inverted T-shaped slider 23 and the inverted T-shaped slider 24 are both fitted with the surface of the roller body 12. A movable plate 28 is fixedly connected to the top of the inverted T-shaped slider 24, and an L-shaped rod 210 is fixedly connected to one side of the inverted T-shaped slider 23. An L-shaped rod 211 is fixedly connected to one side of the second plate 28, and a lower pressure plate 212 is slidably provided below the second L-shaped rod 211. A contact 1 220 is fixedly provided on one side of the lower pressure plate 212, and a second contact 221 is fixedly connected to one side of the lower pressure plate 212. The inverted T-shaped slider 1 23 and the inverted T-shaped slider 2 24 move vertically, so that the second L-shaped rod 211 pushes the lower pressure plate 212 to move downward, so that the second contact 221 abuts against the first contact 220, thereby detecting that the diameter difference between the end and the middle of the sinking roller is too large;

[0045] A second limiting groove 27 is provided on the fixed block 21, and a second movable plate 28 slides in the second limiting groove 27. Two second inverted T-shaped sliders 24 are provided, sliding on both ends of the fixed block 21 respectively. The two second inverted T-shaped sliders 24 are staggered and symmetrically arranged, and a second movable plate 28 is fixed on each second inverted T-shaped slider 24;

[0046] The detection assembly also includes a limiting groove 22, a movable plate 25 slides in the limiting groove 22, and a plurality of return springs 26 are fixedly connected to the top of the fixed block 21. The bottom end of one return spring 26 is fixed to the movable plate 25, and the remaining return springs 26 are respectively fixed to a movable plate 28;

[0047] Motion grooves 29 are respectively provided on both sides of the cleaning tank 1. An L-shaped rod 1 210 and an L-shaped rod 211 slide in a motion groove 29. A plurality of guide rods 213 are slidably connected in the motion groove 29. The top of each guide rod 213 is fixed to the lower pressure plate 212. A support spring 1 214 is sleeved on the surface of a guide rod 213. A trigger plate 215 is slidably connected in the motion groove 29. A support spring 216 is fixedly connected between the trigger plate 215 and the motion groove 29. A fixed column 217 is fixedly connected to one side of the trigger plate 215. A rotating plate 218 is rotatably connected to the surface of the fixed column 217. A torsion spring 219 is fixedly connected between the fixed column 217 and the rotating plate 218. Contact 1 220 is fixed on one side of the trigger plate 215.

[0048] Specifically, the existing technology still has some shortcomings in actual use. During long-term use, due to the strong corrosiveness of the alkali solution, the two ends of the roller body 12 are closer to the inner wall of the cleaning tank 1. The alkali solution flow is greatly disturbed here, and local eddies or stagnation areas are easily formed, resulting in a relatively higher alkali solution concentration at the two ends and a slower renewal speed, which aggravates the chemical corrosion effect, causing corrosion pits on the metal surface first, and then the repeated friction of the strip accelerates wear. At the same time, during the transmission of the strip, even with an anti-deviation design, it will still produce slight lateral displacement due to factors such as tension fluctuations and speed changes. The two ends become high-frequency areas of contact and friction between the strip edges, and mechanical wear is more concentrated, making the wear degree of the two ends of the roller body 12 significantly higher than that in the middle, resulting in the roller body 12 The diameter at both ends becomes smaller and the middle part is relatively higher. The middle part of the strip will be subjected to greater support and friction due to the convex roller surface, while the support force at both ends is insufficient, resulting in an imbalance in the lateral force of the strip, causing the strip to slide to one side due to the greater friction in the middle, thereby causing deviation, resulting in the need for continuous deviation correction of the transmitted strip, thereby affecting the strip cleaning rate.

[0049] Therefore, the present invention solves this problem by setting a corresponding structure. The surface of the roller body 12 is grooved. The shape of the groove is spiral and symmetrically distributed from the middle to both sides, forming an inner spiral shape.

[0050] The bottom of the inverted T-shaped slider 1 23 and the inverted T-shaped slider 2 24 is set to be arc-shaped, and multiple sets of balls are set at the bottom of the arc, which contact the surface of the roller body 12 through the balls to reduce wear;

[0051] The first L-shaped rod 210 and the second L-shaped rod 211 are both composed of a long rod and a short rod, and the short rods are both located above the rotating plate 218;

[0052] Initially, the return spring 1 26 is in an elastically released state, the inverted T-shaped slider 1 23 is located above the middle of the roller body 12, and the inverted T-shaped slider 2 24 is located at both ends of the roller body 12;

[0053] During long-term use, the surface of the roller body 12 wears, causing the diameter of the middle part and both ends of the roller body 12 to decrease. When the return spring 1 26 is elastically released to change the diameter of the roller body 12, the inverted T-shaped slider 1 23 and the inverted T-shaped slider 2 24 will move downward, driving the L-shaped rod 1 210 and the L-shaped rod 2 211 to push the lower pressure plate 212 downward. Under the guidance of the guide rod 213, the lower pressure plate 212 drives the contact 2 221 to move downward and elastically compress the support spring 1 214.

[0054] When the diameter difference between the middle and end portions of the roller body 12 is small, the L-shaped rod 1 210 and the L-shaped rod 211 move downward, driving the lower pressure plate 212 to move. At the same time, the short rod portions thereof contact the ends of the rotating plate 218, thereby keeping the rotating plate 218 relatively fixed and driving the trigger plate 215 to move downward synchronously.

[0055] When the diameter of the middle portion of the roller body 12 is larger than the diameter of the end portion, the second L-shaped rod 211 drives the lower pressure plate 212 to move downward, and its short rod contacts one end of the rotating plate 218, causing the rotating plate 218 to rotate around the fixed column 217 and elastically compress the torsion spring 219. The rotation of the rotating plate 218 pushes the first L-shaped rod 210 upward, causing the trigger plate 215 to reset upward for a distance until the second contact 221 abuts against the first contact 220. At this time, the diameter difference between the middle and end portions of the roller body 12 reaches the threshold value.

[0056] The present invention releases elastically through the return spring 1 26, so that when the diameter of the roller body 12 changes, the inverted T-shaped slider 1 23 and the inverted T-shaped slider 2 24 will move downward, driving the L-shaped rod 1 210 and the L-shaped rod 2 211 to push the lower pressure plate 212 downward, so that the lower pressure plate 212 drives the contact 2 221 to move downward under the guidance of the guide rod 213 and elastically compresses the support spring 1 214, and then through the diameter difference between the middle and end parts of the roller body 12, the contact 2 221 is brought into contact with the contact 1 220, and another set of devices is started to clamp the end of the roller body 12, reducing the diameter difference between the end and the middle of the roller body 12, so that the roller body 12 can complete the transmission of the strip steel.

[0057] Example 2

[0058] like Figures 2 to 14 As shown, compared with Example 1, another embodiment of the present invention is:

[0059] like Figure 2 、 Figure 3 、 Figures 7 to 11 As shown, a contraction groove 31 is provided on the inner wall of one side of the cleaning pool 1 of this embodiment, and a plurality of electric telescopic rods 32 are fixedly arranged in the contraction groove 31. The output ends of the plurality of electric telescopic rods 32 are fixedly connected to a fixed ring plate 33, and a fixed circular plate 34 is fixedly connected to one side of the fixed ring plate 33. A plurality of movable plates 35 are slidably connected in the fixed circular plate 34, and a rotating sleeve 36 is rotatably connected to one side of the fixed circular plate 34. One end of the plurality of movable plates 35 slides in the rotating sleeve 36, and an arc-shaped rack 37 is fixedly connected to one side of the rotating sleeve 36.

[0060] A circular plate 38 is fixedly connected to the fixed circular plate 34, and a contraction block 39 is fixedly connected to one side of the circular plate 38. A plurality of contraction grooves 310 are provided in the contraction block 39, and a contraction rod 312 is slidably connected to each contraction groove 310. A contraction spring 313 is fixedly connected between the contraction rod 312 and the contraction groove 310, and one end of the contraction rod 312 is fixedly connected to the arc plate 311.

[0061] A guide rod 314 is fixedly connected to one side of the fixed ring plate 33, and a gear rod 315 is rotatably connected to the inner wall of one side of the cleaning tank 1. The gear rod 315 consists of a rotating rod and a gear. A guide groove is provided on the rotating rod. The guide groove consists of two straight grooves and an arc groove. The arc groove is located in the middle of the two straight grooves, and the two ends of the arc groove are respectively connected to one end of the two straight grooves. The guide rod 314 slides in the guide groove, and the gear rod 315 is on the motion trajectory of the arc rack 37.

[0062] Specifically, a hexagonal slot is provided on one side of the fixed circular plate 34, and guide posts are provided on both sides of the movable plate 35. The guide post on one side slides in the hexagonal slot, and a plurality of straight slots are provided on the rotating sleeve 36. The guide post on the other side of the movable plate 35 slides in the straight slots.

[0063] The arc-shaped rack 37 is meshed with the gear rod 315. In the initial position, the arc-shaped rack 37 is behind the gear of the gear rod 315. A straight groove is opened on the contraction block 39, and this straight groove is outside the cross section of one end of the roller body 12.

[0064] The outer ring of the arc-shaped plate 311 is the same size as the outer ring of the unworn roller body 12. The gear of the gear rod 315 is higher than the arc-shaped rack 37. The upper arc-shaped plate 311 is longer than the lower arc-shaped plate 311. The longer end of the arc-shaped plate 311 is located at the roller surface end of the roller body 12.

[0065] When the gear 315 is in the gear, the guide rod 314 is engaged with the gear of the gear rod 315, and the gear 315 is engaged with the gear of the gear rod 315. The movable plate three 35 moves, causing the multiple movable plates three 35 to move toward the middle of the rotating sleeve 36, thereby pressing the arc plate 311 into the contraction groove two 310, causing it to converge toward the end of the roller surface of the roller body 12 until the arc plate 311 is resisted by the end of the roller surface of the roller body 12, and then the guide rod 314 passes through the arc groove and enters another straight groove. At this time, the arc plate 311 continues to move forward, so that the shorter end of the arc plate 311 is inserted between the strip and the roller surface of the end of the roller body 12, so that after the strip passes through the end of the roller surface of the roller body 12, it can contact the arc plate 311, increase its force area, and increase the friction at both ends of the strip, thereby preventing the strip from sliding to one side due to the large friction in the middle during transmission, thereby causing the problem of offset. It has a certain effect of slowing down the deviation of the strip, thereby slowing down the number of times the correction device corrects the strip, and further improves the speed of strip cleaning.

[0066] The present invention drives the guide rod 314 to move by the movement of the fixed ring plate 33, so that the shorter end of the curved plate 311 approaches the roller surface of the roller body 12, and the gear rod 315 is rotated by the movement of the guide rod 314, thereby causing the rotating sleeve 36 to rotate and drive multiple movable plates 35 to move, so that the middle part pushes the curved plate 311 to converge toward the middle of the roller body 12 until the curved plate 311 is abutted by the end of the roller surface of the roller body 12. Then the guide rod 314 moves into the linear groove of the gear rod 315, so that the shorter end part of the curved plate 311 is inserted between the strip and the roller surface of the end of the roller body 12. After the strip passes through the end of the roller surface of the roller body 12, it can contact the curved plate 311, thereby increasing its force area and increasing the friction force at both ends of the strip, preventing the strip from sliding to one side due to the large friction force in the middle during transmission, thereby causing the problem of deviation. It has a certain effect of slowing down the deviation of the strip, thereby slowing down the number of times the deviation correction device corrects the strip, and further improving the speed of strip cleaning.

[0067] like Figure 7 、 Figures 12 to 14As shown, in this embodiment, one end of the lower pressure plate 212 is fixedly connected to a transmission rack 41, and the transmission rack 41 slides in the motion groove 29. A guide gear 42 is rotatably provided at the bottom of the transmission rack 41, and the transmission rack 41 is engaged with the guide gear 42. A guide rack 43 is slidably provided on the other side of the guide gear 42, and the guide rack 43 is engaged with the guide gear 42. A guide plate 45 is slidably connected in the motion groove 29, and one end of the guide plate 45 is fixedly connected to a return spring 246, and the other end of the return spring 246 is fixedly connected to an abutment block 44, and the abutment block 44 slides in the motion groove 29, and the top of the abutment block 44 is slidably connected to the bottom of the guide rack 43.

[0068] One end of the abutment block 44 abuts against the fixed circular plate 34, and a moving rod 47 is slidably provided above the abutment block 44. One end of the moving rod 47 abuts against the fixed circular plate 34, and an annular liquid storage tank 48 is fixedly provided at one end of the moving rod 47. The annular liquid storage tank 48 is fixed to one end of the contraction block 39. A sac 49 is fixedly connected to the inner side of each arc-shaped plate 311, and a piston rod 411 is fixedly connected to one side of the moving rod 47. The piston rod 411 slides in the annular liquid storage tank 48, and an auxiliary infusion hose 410 is opened between each sac 49 and the annular liquid storage tank 48.

[0069] Specifically, the guide plate 45 moves only in a vertical straight line, and the second return spring 46 has a high rigidity characteristic, so that after the second return spring 46 is reset, it remains straight when a lateral bending force is applied;

[0070] An inverted T-shaped slot is provided on the top of the abutment block 44, and the bottom of the guide rack 43 is inverted T-shaped. The moving rod 47 is composed of a rectangular rod and a wedge-shaped block. The moving rod 47 is on the movement track of the abutment block 44, and the moving rod 47 matches the straight slot shape opened on the contraction block 39;

[0071] The piston rod 411 is composed of a circular plate and two cylinders. The two cylinders are fixed to both ends of the circular plate. The two cylinders pass through the annular liquid storage tank 48. The infusion hose 410 connects the annular liquid storage tank 48 and the capsule 49.

[0072] The material of the bladder 49 and the infusion hose 410 is acid- and alkali-resistant TPU thermoplastic polyurethane, which has a unique molecular structure and can effectively resist acid and alkali corrosion, maintain the integrity and functionality of the material, and also exhibit excellent performance in extreme low and high temperature environments and is also wear-resistant;

[0073] A corrosion-resistant sealing ring is provided between the two cylinders of the piston rod 411 and the annular liquid storage tank 48 to prevent the alkaline solution from entering the annular liquid storage tank 48. The annular liquid storage tank 48 stores a non-Newtonian liquid for filling the capsule 49.

[0074] Initially, the annular liquid storage tank 48 is filled with non-Newtonian liquid. When the lower pressure plate 212 moves downward, the transmission rack 41 moves, causing the guide rack 43 to move upward, thereby driving the abutment block 44 to move upward. Since the return spring 46 has a high rigidity, the abutment block 44 moves upward, driving the guide plate 45 to move upward synchronously, so that the top of the abutment block 44 abuts against the wedge block of the moving rod 47.

[0075] When contact 2 221 abuts contact 1 220, the fixed circular plate 34 will move forward and no longer block the abutment block 44. At this time, the abutment block 44 moves forward under the elastic release of the return spring 2 46, thereby pushing the moving rod 47 to drive the piston rod 411 to move, and injecting the non-Newtonian liquid in the annular liquid storage tank 48 into the capsule 49, so that the capsule 49 expands and fills the gap between the arc plate 311 and the roller body 12, avoiding the problem that when there is a gap between the arc plate 311 and the roller body 12, the strip will be compressed and deformed when passing through the arc plate 311, making the arc plate 311 more supportive, ensuring the stability of the strip when passing through the surface of the arc plate 311, and making the strip evenly stressed when passing through the arc plate 311.

[0076] like Figures 2 to 14 The roller body 12 shown passes through the fixed ring plate 33, the fixed circular plate 34, the rotating sleeve 36, the circular ring plate 38, the shrinking block 39 and the middle part of the annular liquid storage box 48 without interfering with the inner wall thereof.

[0077] Specifically, the purpose of the above arrangement is to prevent one end of the roller 12 from colliding with the above components during movement, thereby preventing the operation of the components from being affected.

[0078] Working principle:

[0079] During long-term use, the surface of the roller body 12 wears, causing the diameter of the middle part and both ends of the roller body 12 to decrease. When the return spring 1 26 is elastically released to change the diameter of the roller body 12, the inverted T-shaped slider 1 23 and the inverted T-shaped slider 2 24 will move downward, driving the L-shaped rod 1 210 and the L-shaped rod 2 211 to push the lower pressure plate 212 downward. Under the guidance of the guide rod 213, the lower pressure plate 212 drives the contact 2 221 to move downward and elastically compress the support spring 1 214.

[0080] When the diameter difference between the middle and end portions of the roller body 12 is small, the L-shaped rod 1 210 and the L-shaped rod 211 move downward, driving the lower pressure plate 212 to move. At the same time, the short rod portions thereof contact the ends of the rotating plate 218, thereby keeping the rotating plate 218 relatively fixed and driving the trigger plate 215 to move downward synchronously.

[0081] When the diameter of the middle portion of the roller body 12 is larger than the diameter of the end portion, the second L-shaped rod 211 drives the lower pressure plate 212 to move downward, and its short rod contacts one end of the rotating plate 218, causing the rotating plate 218 to rotate around the fixed column 217 and elastically compress the torsion spring 219. The rotation of the rotating plate 218 pushes the first L-shaped rod 210 upward, causing the trigger plate 215 to reset upward for a distance until the second contact 221 abuts against the first contact 220. At this time, the diameter difference between the middle and end portions of the roller body 12 reaches the threshold value.

[0082] When the lower pressing plate 212 moves downward, the guide rack 43 moves upward through the movement of the transmission rack 41, thereby driving the abutment block 44 to move upward. Since the return spring 46 has a high rigidity characteristic, the abutment block 44 moves upward and drives the guide plate 45 to move upward synchronously, so that the top of the abutment block 44 abuts against the wedge block of the moving rod 47.

[0083] When the second contact 221 is in contact with the first contact 220, the electric telescopic rod 32 is started so that its output end drives the fixed ring plate 33 to move, and the arc rack 37 is driven to move by the fixed ring plate 33, so that the shorter end of the arc plate 311 is close to the roller surface of the roller body 12. The movement of the fixed ring plate 33 drives the guide rod 314 to move, so that the guide rod 314 slides in the linear groove of the gear rod 315. When it slides at the connection between the linear groove and the arc groove, the arc rack 37 is meshed with the gear of the gear rod 315. Then, as the fixed ring plate 33 moves, the guide rod 314 enters the arc groove. Under the guiding action of the arc groove, the gear rod 315 rotates, thereby passing through the arc groove. The rack 37 rotates the rotating sleeve 36. Under the guidance of the straight groove of the rotating sleeve 36 and the hexagonal groove of the fixed circular plate 34, the plurality of movable plates 3 35 are pushed to move, so that the plurality of movable plates 3 35 move toward the middle of the rotating sleeve 36, thereby pressing the arc plate 311 into the second contraction groove 310, so that it converges toward the end of the roller surface of the roller body 12 until the arc plate 311 is abutted by the end of the roller surface of the roller body 12. Then, the guide rod 314 passes through the arc groove and enters another straight groove. At this time, the arc plate 311 continues to move forward, so that the shorter end of the arc plate 311 is inserted between the strip and the roller surface of the end of the roller body 12, so that the strip can contact the arc plate 311 after passing through the end of the roller surface of the roller body 12.

[0084] When contact 2 221 abuts contact 1 220 , the fixed circular plate 34 will move forward and no longer block the abutment block 44 . At this time, the abutment block 44 moves forward under the elastic release of the return spring 2 46 , thereby pushing the moving rod 47 to drive the piston rod 411 to move, and injecting the non-Newtonian liquid in the annular liquid storage tank 48 into the capsule 49, causing the capsule 49 to expand and fill the gap between the arc plate 311 and the roller body 12 .
