Description

Technical Field

[0001] This invention relates to the technical field of heat treatment of steel strips, and more specifically to a heat treatment device for processing steel strips. Background Technology

[0002] Steel strip heat treatment is a process of heating, holding, and cooling cold-rolled or hot-rolled steel strip. It does not change the external dimensions of the steel strip. The core is to adjust the internal structure to improve strength and hardness, toughness and plasticity, eliminate processing stress, and refine uniform grains, so that the performance of the steel strip is more suitable for actual use needs.

[0003] Patent document CN222119336U discloses a heat treatment device for steel strip, including a housing. Multiple rotating rollers are rotatably connected inside the housing. Multiple buffer grooves are formed on both sides of the housing. A clamping assembly is installed between adjacent buffer grooves. Slide rails are fixedly connected to both sides of the inner wall of the housing. Sliding blocks are slidably connected to both sides of the outer periphery of the slide rails. A limit frame is fixedly connected to the top of each sliding block. A guide wheel is rotatably connected inside the limit frame. An adjusting screw is rotatably connected to the middle of the bottom of the slide rail. A threaded sleeve is threadedly connected to the outer periphery of the adjusting screw. A connecting rod is installed between the threaded sleeve and the sliding block.

[0004] During the heat treatment of steel strip, the steel strip passes between two guide wheels 7 on one side, then between two movable plates, and subsequently enters between multiple sets of rotating rollers and pressure rollers. The steel strip is pressed onto the rotating rollers by a clamping assembly. Afterward, the steel strip passes between two guide wheels on the other side and is connected to the traction equipment. At this point, the worker turns the handle at the bottom of the adjusting screw, causing the adjusting screw to rotate, which in turn moves the threaded sleeve up or down along the outer circumference of the adjusting screw. This, in turn, pulls two connecting rods, which synchronously drive two sliders to move in opposite directions along the outer circumference of the slide rail, adjusting the distance between the two limit frames and guide wheels on the same side. This ensures that the two guide wheels on the same side are in contact with both sides of the steel strip, assisting in the conveying of the steel strip.

[0005] However, this solution also has the following problems. During the steel strip conveying process, the guide wheel needs to continuously contact the side of the steel strip to achieve limiting guidance. However, when continuously conveying thin steel strips, the side of the strip will continuously rub and cut against the contact surface of the guide wheel. After long-term operation, scratches, grooves, and even local wear will gradually appear on the side of the guide wheel. This not only damages the guiding accuracy of the guide wheel, but also exacerbates the vibration of the steel strip during conveying due to uneven contact surfaces, further affecting the guiding stability. In addition, if the steel strip deviates during the conveying process due to improper equipment adjustment, uneven tension, or other factors, the contact force between its one side and the guide wheel will increase sharply. This concentrated pressure will cause irreversible extrusion deformation on the side of the thin steel strip, such as curling or dents. This not only damages the edge flatness of the steel strip, but also directly affects the accuracy of subsequent processing steps such as cutting, stamping, and welding, ultimately leading to a decline in product quality. Summary of the Invention

[0006] This invention provides a heat treatment device for steel strip processing, which aims to solve the problems in related technologies where guide wheels are easily damaged and steel strips are easily deformed during the conveying of thin-gauge steel strips, thus affecting processing accuracy.

[0007] The heat treatment equipment for steel strip processing of the present invention includes a conveying roller installed inside a housing for conveying steel strip. A mounting frame is provided inside the housing, and two sets of pushing components and two sets of correcting components are mounted on the mounting frame. The two sets of components are symmetrically arranged on both sides of the steel strip. The pushing component includes: a pushing roller slidably mounted on the mounting frame and a connecting member connected to the pushing roller. The pushing roller is located on one side of the steel strip and spaced apart from the steel strip. The correcting component includes: a correcting sleeve slidably mounted on the mounting frame and a correcting wheel located below the correcting sleeve. The correcting wheel corresponds to the edge of the steel strip and is located above it. Its rotation axis forms a preset angle with the steel strip conveying direction, so that when it comes into contact with the steel strip, it can push the steel strip to deviate away from the pushing roller. The pushing roller is connected to the correcting sleeve through the connecting member. When the steel strip deviates, it pushes against the pushing roller, and the correcting sleeve is moved down through the connecting member so that the correcting wheel comes into contact with the steel strip. The correcting wheel corrects the position of the steel strip. After the steel strip returns to its normal position and separates from the correcting wheel, the correction is completed, and the connecting member then drives the correcting wheel to reset.

[0008] Its effect is that when the steel belt deviates during conveying and shifts to one side, it first contacts and pushes against the push roller on that side. The push roller, under this thrust, transmits the force to the correction sleeve via the connector, causing the correction sleeve to slide downwards along the mounting frame. This, in turn, causes the correction wheel below the correction sleeve to move down and contact the edge of the steel belt. At this point, due to the preset angle between the correction wheel's rotation axis and the steel belt's conveying direction, the force generated by its contact with the steel belt pushes the steel belt away from the push roller on that side, i.e., it shifts towards its normal position, completing the position correction. When the steel belt returns to its normal conveying position, it no longer pushes against the push roller and separates from the correction wheel. The connector then drives the correction sleeve to slide upwards and reset, and the correction wheel also detaches from the steel belt and returns to its initial position, awaiting the next possible correction trigger. Adjusting the position of the steel belt through the correction wheel reduces deformation and improves the processing accuracy of the steel belt.

[0009] Preferably, the connecting component includes: an inclined block, a connecting rod, a receiving block connected to the push roller is slidably mounted on the mounting frame, and a correction sleeve includes: an intermediate rod that slidably engages with the mounting frame, an intermediate sleeve that slides vertically and horizontally around the intermediate rod, and an elastic element 1 that is disposed between the intermediate sleeve and the intermediate rod and connects the two. The two ends of the connecting rod are respectively connected to the receiving block and the intermediate rod. The correction wheel is connected to the intermediate sleeve. The intermediate sleeve includes an abutment portion. The elastic element 1 drives the abutment portion to slide and abut against the inclined surface of the inclined block.

[0010] Its effect is that when the steel belt comes into contact with the push roller and drives the push roller to move, the push roller moves through the receiving block and the connecting rod, the connecting rod drives the intermediate rod to move, and the movement of the intermediate rod drives the intermediate sleeve to come into contact with the inclined block, so as to drive the correction wheel to move closer to the steel belt.

[0011] Preferably, a support frame is provided at the bottom of the intermediate sleeve, and a support block is slidably mounted inside the support frame. The correction wheel is rotatably connected to the support block. A gear is provided on the shaft of the correction wheel, and a rack that meshes with the gear is fixedly provided on the side wall of the support frame. When the correction wheel contacts and rotates with the steel belt, the gear rotates and drives the support block to move downward so that the correction wheel presses against the steel belt. A limiting component connected to the support block is provided on the intermediate sleeve. After the correction wheel presses against the steel belt, the gear and the rack separate, and the limiting component fixes the position of the intermediate sleeve.

[0012] Its effect is that when the straightening wheel comes into contact with the steel belt, the limiting component fixes the straightening sleeve and the push roller, so that the straightening wheel and the steel belt remain in contact, so that the steel belt can be adjusted to the designated position by the straightening wheel.

[0013] Preferably, the intermediate sleeve includes an extension located on one side of the inclined block. The intermediate sleeve has a placement groove, and a guide slope one is provided on the side wall of the placement groove. The limiting component includes a limiting block, a top block, and a pull rope. The limiting block is located on the side of the extension near the inclined block. The limiting block is provided with a guide slope two that slides against the extension. The top block slides against the guide slope one. One end of the pull rope is connected to the support block, and the other end is connected to the top block. The top block abuts against the limiting block. The movement of the support block drives the top block to move through the pull rope. Under the action of the guide slope one, the top block pushes the limiting block to move. Under the action of the guide slope two, the limiting block moves towards the outside of the placement groove and abuts against the inclined block to fix the intermediate sleeve.

[0014] Its effect is that after the correction wheel comes into contact with the steel belt, it will rotate under the drive of the steel belt. The rotation of the correction wheel moves closer to the steel belt again through the gear and rack to press the steel belt. At the same time, the pull rope drives the top block to push the limit block to move, so that the limit block moves between the extension and the inclined block, thereby fixing the correction sleeve and the push roller.

[0015] Preferably, there are two inclined blocks, with the extension located between the two inclined blocks. There are also two limiting blocks corresponding to the two inclined blocks. An elastic element two is provided between the two limiting blocks to connect them. An elastic element three is sleeved on the outside of the pull rope and connected to the support block. The end of the elastic element three away from the support block is connected to the middle sleeve. The elastic element three is used to drive the support block to move upward.

[0016] Preferably, the side of the extension is spaced apart from the inclined block, and the limiting block is inserted between the extension and the inclined block under the action of the second guide inclined surface to fix the intermediate sleeve.

[0017] Preferably, the mounting frame is provided with an elastic element four, which is connected to the receiving block. The elastic element four is used to drive the receiving block to move in the direction of the steel strip.

[0018] Preferably, the correction wheel is made of rubber. When the support block moves the correction wheel downward, the correction wheel deforms to press the steel belt.

[0019] Preferably, each set of correction components includes two correction wheels, which are located on the upper and lower sides of the steel belt respectively. Two sets of connectors are also provided corresponding to the two correction wheels. When the push roller moves, the correction wheels are driven to move synchronously through the two sets of connectors.

[0020] Preferably, there are two mounting brackets, each corresponding to one of the two sets of calibration components. A bidirectional screw is rotatably mounted inside the housing. The two sections of the bidirectional screw with opposite threads respectively engage with the two mounting brackets. A handwheel is provided at the end of the bidirectional screw.

[0021] Beneficial effects: This invention, through the push roller, the correction wheel, and related structures, allows the steel belt to deviate slightly without contacting the push roller during conveying. When the deviation is large, the steel belt comes into contact with the push roller and pushes it to move. The push roller drives the correction wheel to move closer to the steel belt. The correction wheel moves down to contact and press the steel belt, correcting its position. During the correction process, the limit block fixes the correction sleeve. After the correction is completed, the correction wheel separates from the steel belt, and then all components reset. This controls the steel belt to float within a specified range, preventing the steel belt from deviating or deforming on the side during conveying, thus improving processing accuracy.

Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figures 1 to 13 As shown, the heat treatment equipment for steel strip processing of the present invention includes a housing 1, a conveying roller 12, and an induction heating coil 11. An inlet and an outlet are provided on both sides of the housing 1. The conveying roller 12 and the induction heating coil 11 are both disposed inside the housing 1. During operation, the steel strip 01 continuously enters the housing 1 through the inlet and moves at a constant speed along a predetermined path under the traction of the conveying roller 12. When the steel strip 01 passes through the effective range of the induction heating coil 11, the alternating magnetic field generated by the coil forms eddy currents inside the steel strip 01, thereby achieving rapid and uniform electromagnetic induction heating and completing targeted heat treatment processes such as quenching and tempering. After heat treatment, the steel strip 01 is continuously conveyed by the conveying roller 12 and smoothly discharged to the outside of the housing 1 through the outlet.

[0038] Reference Figures 2 to 6 A mounting frame 2 is provided inside the housing 1. A pushing component 3 and a correcting component 4 are mounted on the mounting frame 2. Two sets of pushing components 3 are located on either side of the steel belt 01. Two sets of correcting components 4 are also located on either side of the steel belt 01. When the steel belt 01 deviates during transport, the pushing component 3 and the correcting component 4 work together to correct the steel belt 01, ensuring it follows a predetermined trajectory, preventing deformation, and improving the processing accuracy of the steel belt 01.

[0039] Reference Figures 6 to 10The calibration assembly 4 includes a calibration sleeve 41 and a calibration wheel 42. The calibration sleeve 41 is slidably mounted on the mounting frame 2, and is located above the steel belt 01. The calibration wheel 42 is mounted on the calibration sleeve 41 and located below the calibration sleeve 41, also above the steel belt 01. The calibration wheel 42 corresponds to the edge of the steel belt 01. During normal conveying, the calibration wheel 42 and the steel belt 01 are vertically offset. When the steel belt 01 deviates, its side moves to below the calibration wheel 42.

[0040] Reference Figure 7 , Figure 8 , Figure 10 The correction wheel 42 is rotatably mounted on the correction sleeve 41. The rotation axis of the correction wheel 42 is set at an angle to the conveying direction of the steel belt 01, that is, the side of the correction wheel 42 closest to the center of the steel belt 01 is set towards the feed inlet of the housing 1. When the correction wheel 42 comes into contact with the steel belt 01, the correction wheel 42 will rotate as the steel belt 01 is conveyed. When the correction wheel 42 rotates, it will drive the steel belt 01 to move towards the center of the conveying roller 12 to correct the position of the steel belt 01.

[0041] During the automated conveying process of steel belt 01, if the steel belt 01 deviates from the preset conveying range due to factors such as equipment vibration or conveying path deviation, its edge will contact the pushing component 3. The pushing component 3 will generate a downward driving force, causing the correction sleeve 41 connected to it to move downward. During the downward movement, the correction sleeve 41 will drive the correction wheel 42 to move in the same direction until the correction wheel 42 abuts against the side of the steel belt 01. At this time, as the steel belt 01 continues to convey forward at the original conveying speed, the correction wheel 42 will rotate synchronously under the action of the friction of the steel belt 01. Since the correction wheel 42 is set with a specific angle of inclination, it will generate a lateral component force when it rotates. This component force will continue to act on the side of the steel belt 01, causing the steel belt 01 to gradually move away from the pushing component 3, thereby gradually correcting the deviation trajectory and achieving accurate resetting of the steel belt 01. Once the steel belt 01 has fully returned to the preset conveying path, its side naturally separates from the correction wheel 42. The pushing component 3 drives the correction sleeve 41 and the correction wheel 42 to reset upward along the original guide structure, restoring them to their initial state. This is to cope with possible deviations of the steel belt 01 in the future and ensure the continuity of the conveying process.

[0042] Throughout the entire adjustment process of the steel belt 01 position, the straightening wheel 42 remains in contact with the side of the steel belt 01. As the straightening wheel 42 rotates, the static friction generated between it and the steel belt 01 applies a lateral adjustment force. This adjustment method minimizes wear on the surface of the steel belt 01 and avoids problems such as localized deformation and wrinkling caused by rigid straightening, effectively protecting the original physical properties and surface quality of the steel belt 01. Furthermore, this straightening structure design does not require any interruption to the conveying process of the steel belt 01, allowing for dynamic straightening to be completed during continuous operation of the steel belt 01.

[0043] Reference Figure 5 , Figure 6 , Figure 7 , Figure 9 The pushing component 3 includes a pushing roller 31 and a connecting member 32. The pushing roller 31 is arranged in a vertical direction and is slidably mounted on the mounting frame 2 in a horizontal direction. The pushing roller 31 is located on one side of the steel strip 01 and is spaced apart from the steel strip 01. The connecting member 32 is also mounted on the mounting frame 2. The pushing roller 31 is connected to the correction sleeve 41 through the connecting member 32.

[0044] When the steel strip 01 deviates, it contacts the push roller 31, causing the push roller 31 to move synchronously. When the push roller 31 moves, it drives the correction sleeve 41 to move through the connector 32, thereby adjusting the position of the correction wheel 42.

[0045] Reference Figure 9 A receiving block 311 is slidably mounted on the mounting frame 2. The sliding direction of the receiving block 311 is the same as the sliding direction of the push roller 31, and the push roller 31 and the receiving block 311 are rotatably engaged. The connecting member 32 includes an inclined block 321 and a connecting rod 322. One end of the connecting rod 322 is connected to the receiving block 311, and the other end is connected to the correction sleeve 41. The receiving block 311 is located on the side of the correction sleeve 41 away from the steel strip 01, and the inclined block 321 is set on the mounting frame 2 and engages with the correction sleeve 41.

[0046] When the push roller 31 moves, the push roller 31 drives the receiving block 311 to move. The movement of the receiving block 311 drives the correction sleeve 41 to move through the connecting rod 322. At the same time, the correction sleeve 41 moves and, under the action of the inclined block 321, drives the correction wheel 42 to move closer to the steel strip 01.

[0047] Reference Figure 9 , Figure 10 , Figure 11The calibration sleeve 41 includes: an intermediate rod 411, an intermediate sleeve 412, and an elastic element 413. The intermediate rod 411 is slidably mounted on the mounting bracket 2. The connecting rod 322 is connected to the intermediate rod 411. The intermediate sleeve 412 is slidably mounted on the intermediate rod 411, i.e., the intermediate sleeve 412 is sleeved on the outside of the intermediate rod 411. The elastic element 413 is a spring and is disposed inside the intermediate sleeve 412. The elastic element 413 is connected to both the intermediate sleeve 412 and the intermediate rod 411. The elastic element 413 is used to drive the intermediate sleeve 412 to move upward. An abutment part 5 is provided above the intermediate sleeve 412, i.e., the elastic element 413 drives the intermediate sleeve 412 to move upward, causing the abutment part 5 to maintain contact with the inclined surface of the inclined block 321. The calibration wheel 42 is disposed on the calibration sleeve 41.

[0048] When the connecting rod 322 moves, it drives the intermediate rod 411 to move. The movement of the intermediate rod 411 drives the intermediate sleeve 412 to move accordingly. Under the action of the inclined block 321, the intermediate sleeve 412 moves horizontally and downwards, thereby driving the correction wheel 42 to move vertically to adjust the position of the correction wheel 42.

[0049] Reference Figure 9 , Figure 11 , Figure 12 A support frame 6 is provided at the bottom of the intermediate sleeve 412. A support block 61 is slidably mounted inside the support frame 6. The correction wheel 42 is rotatably connected to the support block 61, meaning that the correction wheel 42 can move up and down within the support frame 6 via the support block 61. A gear 421 is provided on the rotating shaft of the correction wheel 42. A rack 62 is fixedly provided on the side wall of the support frame 6, and the rack 62 is arranged vertically. The gear 421 meshes with the rack 62. A limit component 7 is provided on the intermediate sleeve 412 and is connected to the intermediate sleeve 412.

[0050] The correction sleeve 41 stops moving when it reaches its limit position. When the correction sleeve 41 reaches its limit position, it drives the correction wheel 42 to abut against the side of the steel belt 01. The limiting component 7 fixes the position of the correction sleeve 41. As the steel belt 01 continues to be conveyed, it drives the correction wheel 42 to rotate. The rotation of the correction wheel 42 drives the gear 421 to rotate. Under the action of the rack 62, the gear 421 drives the correction wheel 42 to continue to move downward until the gear 421 separates from the rack 62, so that the correction wheel 42 can further press the steel belt 01. Due to the action of the rack 62, the gear 421 will always be below the rack 62 when rotating, ensuring that the correction wheel 42 presses the steel belt 01 tightly and increases the friction between the two, so as to adjust the position of the steel belt 01.

[0051] The correction wheel 42 is made of rubber, meaning it can deform. When the support block 61 drives the correction wheel 42 to press the steel belt 01, the correction wheel 42 can deform, increasing the pressure applied to the steel belt 01 and simultaneously increasing the contact area between the correction wheel 42 and the steel belt 01, thus increasing the friction between them.

[0052] Reference Figure 9 , Figure 10 , Figure 11 , Figure 13 The intermediate sleeve 412 also includes an extension 51, which is located on one side of the inclined block 321. A placement groove 52 is provided on the intermediate sleeve 412, and a guide inclined surface 521 is provided on the side wall of the placement groove 52. The limiting component 7 is disposed in the placement groove 52.

[0053] Reference Figures 10 to 13 The limiting component 7 includes: a limiting block 71, a top block 72, and a pull rope 73. The limiting block 71 is installed in the placement groove 52 and is located on the side of the extension 51 near the inclined block 321. A second guide inclined surface 711 is provided on the limiting block 71, and the second guide inclined surface 711 abuts against the inner wall of the placement groove 52. The limiting block 71 is horizontally slidably assembled in the placement groove 52. The top block 72 is vertically slidably assembled in the placement groove 52, and at the same time, the top block 72 abuts against the first guide inclined surface 521. The top block 72 is located on one side of the limiting block 71 and abuts against the limiting block 71. One end of the pull rope 73 is connected to the support block 61, and the other end is connected to the top block 72.

[0054] When the calibration sleeve 41 moves to its limit position, the calibration wheel 42 abuts against the side of the steel belt 01. The rotation of the calibration wheel 42 drives the support block 61 to move. The support block 61 drives the top block 72 to move downward through the pull rope 73. While moving downward, the top block 72 engages with different positions on the first guide slope 521. Under the action of the first guide slope 521, the top block 72 moves closer to the limiting block 71, thereby pushing the limiting block 71 to move. When the limiting block 71 moves, different positions on the second guide slope 711 on its side abut against the inner wall of the placement groove 52, so that the limiting block 71 moves closer to and abuts against the inclined block 321 to fix the position of the calibration sleeve 41.

[0055] Reference Figures 10 to 13Two inclined blocks 321 are provided, spaced apart along the conveying direction of the steel belt 01. The inclined surface of the inclined block 321 is inclined downwards towards the steel belt 01 on the side away from the steel belt 01. The extension 51 is located in the middle of the abutment part 5. Both inclined blocks 321 abut against the abutment part 5, and the extension 51 is located between the two inclined blocks 321. Two limiting blocks 71 are provided corresponding to the two inclined blocks 321. An elastic element 2 8 is provided between the two limiting blocks 71. The elastic element 2 8 is a spring. Both ends of the elastic element 2 8 are connected to the two limiting blocks 71 respectively. The elastic element 2 8 is used to drive the two limiting blocks 71 to move closer to each other. An elastic element 3 81 is sleeved on the outside of the pull rope 73. The elastic element 3 81 is a spring. One end of the elastic element 3 81 is connected to the support block 61, and the other end is connected to the intermediate sleeve 412. The elastic element 3 81 is used to drive the support block 61 to move upwards.

[0056] When the top block 72 moves the limiting block 71, and the limiting block 71 moves closer to the inclined block 321, the two limiting blocks 71 move away from each other, simultaneously stretching the elastic element 81. Furthermore, when the support block 61 moves downwards, it stretches the elastic element 81. This causes the correction wheel 42 to contact the steel belt 01, where the limiting block 71 and the inclined block 321 cooperate to fix the correction sleeve 41. Simultaneously, the connecting rod 322 and the receiving block 311 fix the push roller 31.

[0057] When the straightening wheel 42 straightens the steel strip 01, it causes the steel strip 01 to separate from the push roller 31. At this time, the limiting block 71 and the inclined block 321 are still in contact. After the steel strip 01 is straightened, the straightening wheel 42 separates from the steel strip 01 and stops rotating. The elastic element 3 81 drives the support block 61 to move upward, and the gear 421 meshes with the rack 62 again. When the support block 61 moves upward, the elastic element 2 8 pulls the two limiting blocks 71 to move closer to each other. Under the action of the guide inclined surface 2 711, the limiting block 71 pushes the top block 72 to move in the opposite direction, thereby driving the top block 72 to move. After the top block 72 moves to the initial position, the limiting block 71 moves into the placement groove 52 and separates from the inclined block 321, releasing the restriction on the straightening sleeve 41.

[0058] Reference Figure 9 An elastic element 82 is provided on the mounting frame 2. The elastic element 82 is a spring and is connected to the receiving block 311. The elastic element 82 is used to drive the receiving block 311 to move horizontally toward the steel belt 01. When the steel belt 01 drives the push roller 31 to move, the push roller 31 compresses the elastic element 82 through the receiving block 311.

[0059] After the limiting block 71 separates from the inclined block 321, releasing the restriction on the correction sleeve 41, the elastic element 82 drives the receiving block 311 and the connecting rod 322 to move the intermediate rod 411 to the initial position, thereby driving the correction wheel 42 to reset. This allows the position of the steel belt 01 to be readjusted again if it deviates.

[0060] The side of the extension 51 is spaced apart from the inclined block 321. When the top block 72 pushes the limiting block 71 to move horizontally, the limiting block 71 moves in a direction away from the steel strip 01. This allows the top block 72 to be inserted between the extension 51 and the inclined block 321 when the correction sleeve 41 moves to its limit position, thereby fixing the correction sleeve 41.

[0061] Reference Figures 5 to 7 Each set of correction components 4 includes two correction wheels 42, which are located on the upper and lower sides of the steel belt 01, respectively. Two sets of connecting members 32 are also provided corresponding to the two correction wheels 42, and the two connecting members 32 respectively cooperate with both ends of the push roller 31. This allows the push roller 31 to simultaneously drive the two correction wheels 42 to move via the two connecting members 32, so that the two correction wheels 42 abut against both sides of the steel belt 01, thereby correcting and adjusting the position of the steel belt 01.

[0062] Reference Figure 2 , Figure 5 There are two mounting brackets 2, each corresponding to one of the two sets of pushing components 3. A slide rail is installed inside the housing 1, and the mounting brackets 2 slide left and right on the slide rail. A bidirectional screw 9 is rotatably mounted inside the housing 1, with two sections of threads in opposite directions. The threads at both ends of the screw 9 engage with the two mounting brackets 2 respectively. A handwheel 91 is coaxially mounted at the end of the bidirectional screw 9. The handwheel 91 rotates the bidirectional screw 9, causing the two mounting brackets 2 to move in opposite directions, thus adjusting the distance between the two sets of pushing components 3 according to the different widths of the steel strips 01.

[0063] The implementation principle of this invention is as follows: Initially, the steel belt 01 is conveyed normally, the correction wheel 42 is located above the side of the steel belt 01, and the push roller 31 is arranged at intervals with the side of the steel belt 01. When the steel belt 01 deviates slightly without affecting its heat treatment, the steel belt 01 does not contact the push roller 31. When the steel belt 01 deviates significantly during conveying, it will contact the push roller 31. The steel belt 01 is configured to contact the push roller 31 when a significant deviation occurs, and then the position of the steel belt 01 is adjusted by the correction wheel 42. This controls the steel belt 01 to float within a specified range, avoiding large-scale shaking or deviation.

[0064] When the steel strip 01 is not deviated, the intermediate rod 411 moves away from the steel strip 01. At the same time, the correction sleeve 41 drives the correction wheel 42 to move downward under the action of the inclined block 321. When the correction sleeve 41 moves to the limit position, the correction wheel 42 corresponds to the edge of the steel strip 01.

[0065] When the steel strip 01 comes into contact with the push roller 31, the steel strip 01 is located below the correction wheel 42. The push roller 31 drives the intermediate rod 411 to move through the receiving block 311 and the connecting rod 322. The movement of the intermediate rod 411 drives the correction sleeve 41 to move. The correction sleeve 41 moves and comes into contact with different positions on the inclined block 321, driving the correction sleeve 41 to move downward. At the same time, the movement of the correction sleeve 41 drives the correction wheel 42 to move downward until the correction wheel 42 comes into contact with the steel strip 01.

[0066] After the correction wheel 42 comes into contact with the steel belt 01, the correction sleeve 41 moves to its limit position and stops moving. The steel belt 01 continues to convey and drive the correction wheel 42 to rotate. The rotation of the correction wheel 42 continues to move downward through the gear 421 and the rack 62 to press the steel belt 01. When the gear 421 moves, it drives the support block 61 to move. The movement of the support block 61 drives the top block 72 to move downward through the pull rope 73. Under the action of the first guide slope 521, the top block 72 pushes the limit block 71 to move. Under the action of the second guide slope 711, the limit block 71 moves horizontally and moves towards the outside of the placement groove 52, so that the limit block 71 is inserted between the extension 51 and the inclined block 321 to fix the correction sleeve 41, and then fix the push roller 31.

[0067] The correction wheel 42 rotates with the steel belt 01 and corrects the position of the steel belt 01, which will cause the steel belt 01 to separate from the push roller 31. At this time, the correction sleeve 41 is still in a fixed state. During the correction of the steel belt 01, the gear 421 and the rack 62 are continuously separated. After the steel belt 01 is corrected, the steel belt 01 separates from the correction wheel 42, the correction wheel 42 stops rotating, the elastic element three 81 drives the support block 61 to move upward, so that the gear 421 meshes with the rack 62 again. At the same time, the elastic element two 8 drives the limit block 71 and the top block 72 to reset, releasing the restriction on the correction sleeve 41. Then the elastic element four 82 drives the receiving block 311 and the intermediate rod 411 to reset, so as to drive the correction wheel 42 to move to the initial position.

[0068] By setting the push roller 31 and the correction wheel 42, when the steel belt 01 deviates, the correction wheel 42 abuts against the side of the steel belt 01 to correct the position of the steel belt 01, so as to avoid the steel belt 01 from shifting or deforming its side during conveying, and improve the processing accuracy of the steel belt 01.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
