Description

Technical Field

[0001] This invention relates to the field of steel strip manufacturing technology, and in particular to a cleaning device. Background Technology

[0002] In the production process of precision stainless steel strip, after cold rolling, slitting, and transfer, the surface of the strip inevitably accumulates various impurities such as rolling oil, metal powder, iron filings, and environmental dust. Bright annealing is one of the core processes in the finishing of precision stainless steel strip. If the impurities on the strip surface are not thoroughly removed before annealing, the residual oil and solid impurities will carbonize and sinter during the high-temperature annealing process, forming irreversible defects such as black spots, pitting, and color differences on the steel strip surface. This severely reduces the surface appearance quality and corrosion resistance of the finished product, failing to meet the reliability requirements of high-end downstream applications such as electronic components and precision mechanical parts. Therefore, surface cleaning before annealing is a crucial process for ensuring the quality of finished precision stainless steel strip.

[0003] Currently, the industry generally adopts a continuous pass-through spray cleaning process for this process. The steel strip is continuously pulled through the cleaning station by the unwinding and rewinding mechanism. The cleaning station is equipped with a fixed arrangement of spray pipes and high-pressure nozzles. Cleaning liquid is sprayed onto the upper and lower surfaces of the moving steel strip with a pre-set constant water pressure and constant flow rate. The impurities attached to the surface of the strip are removed by the flushing action of the water flow.

[0004] The existing spray cleaning solutions described above have several technical drawbacks. Firstly, the cleaning quality is not consistently stable and cannot adapt to varying levels of contamination. In actual production, the degree of surface contamination varies significantly between different sections or batches of the same steel coil. Heavily contaminated sections have a greater amount and stronger adhesion of impurities, and a spray system with fixed parameters cannot specifically enhance its rinsing capacity, often resulting in incomplete cleaning of heavily contaminated sections. Residual impurities, after annealing, form surface defects, increasing the product scrap rate. Secondly, the cleaning energy consumption is high, leading to high operating costs. To ensure a high cleaning pass rate under the dirtiest conditions, operators typically set the spray water pressure and flow rate to high, conservative values. However, most steel strips are in a lightly contaminated state during production. A constant, high-flow-rate spray mode results in a significant and unnecessary waste of water resources and pumping energy, substantially increasing the water and energy consumption of the production line.

[0005] Therefore, there is an urgent need for a cleaning device to solve the above-mentioned technical problems. Summary of the Invention

[0037] Combination Figure 1 , Figure 2 As shown, this embodiment provides a cleaning device, which includes a frame 1, an unwinding roller 2, a winding roller 3, a cleaning assembly 4, a detection assembly 5, and a control assembly.

[0038] The aforementioned frame 1 is, for example, a frame structure formed by combining multiple mounting plates or mounting rods. Exemplarily, the frame 1 includes a mounting base plate and mounting side plates. The mounting base plate is parallel to the ground, and the mounting side plates are perpendicular to the surface of the mounting base plate and located on one side of the mounting base plate, forming an L-shaped frame structure. Further, multiple support blocks are provided on the lower side of the mounting base plate, arranged in a rectangular array. The aforementioned unwinding roller 2 is rotatably mounted on the frame 1, and is used to unwind the steel strip 10 to be cleaned. The aforementioned winding roller 3 is also rotatably mounted on the frame 1, and is arranged parallel and spaced apart from the unwinding roller 2, used to wind up the cleaned steel strip 10. Regarding the rotatable mounting of the unwinding roller 2 and winding roller 3 on the frame 1, exemplarily, multiple vertically arranged support columns are also provided on the upper side of the mounting base plate, and these support columns are parallel to and spaced apart from each other. Taking the unwinding roller 2 as an example, one end of the unwinding roller 2 is rotatably connected to the mounting side plate, and the other end is rotatably connected to the corresponding support column.

[0039] Combination Figure 2 , Figure 3 As shown, the cleaning assembly 4 is mounted on the frame 1 and located between the unwinding roller 2 and the take-up roller 3. The cleaning assembly 4 includes a cleaning component 41, a water inlet baffle 42, and a first drive component 43.

[0040] The aforementioned cleaning components 41 are multiple, and the multiple cleaning components 41 are spaced apart along a first direction X1, where the first direction X1 is a horizontal direction. Each cleaning component 41 includes two water spray pipes 411 spaced apart along a second direction X2, where the second direction X2 is a vertical direction. Exemplarily, the water spray pipes 411 extend along a third direction X3, where the third direction X3, the aforementioned first direction X1, and the second direction X2 are arranged at an angle to each other, for example, 90°. The cross-sectional shape of the water spray pipe 411 is rectangular (i.e., the water spray pipe 411 is a square tube), and multiple water spray holes are opened on the side where two water spray pipes 411 meet and face each other. Further, a nozzle is also provided at each water spray hole to increase the water spray pressure. Furthermore, the axis of the nozzle is arranged at an angle to the surface of the steel belt 10, and the axis of the nozzle is inclined downstream along the conveying direction of the steel belt 10. For example, using the nozzle itself as a reference, the steel belt 10 moves from the left side of the nozzle to the right side of the nozzle; that is, the left side of the nozzle is the upstream side of the steel belt 10, and the right side of the nozzle is the downstream side of the steel belt 10, with the nozzle axis tilted to the right. With this configuration, the tilted spray of cleaning water can create a tangential scouring force on the surface of the steel belt 10, more effectively removing metal powder, iron filings, oil stains, and other contaminants adhering to the surface of the steel belt 10, thus improving the cleaning effect.

[0041] In addition, a water tank is provided on the same side of the two water spray pipes 411, and both water spray pipes 411 are connected to the water tank (that is, each of the two water spray pipes 411 has a water inlet on one side, and the water inlet is connected to the water tank), and the water tank is connected to the water supply source. Of course, the water inlets of the two water spray pipes 411 can also be directly connected to the water supply source. The steel strip 10 to be cleaned is threaded between the two water spray pipes 411, and the two water spray pipes 411 can spray cleaning water onto the steel strip 10 to be cleaned.

[0042] Multiple water inlet baffles 42 are provided, each positioned at the water inlet of a cleaning assembly 41 (i.e., the water inlets of the two spray pipes 411 in the cleaning assembly 41), capable of blocking the water inlets. The first drive assembly 43 is connected to the multiple water inlet baffles 42, driving them to move and change the opening / closing degree of the water inlets. For example, the first drive assembly 43 is arranged along the second direction X2 (i.e., the vertical direction), and is either an electric or pneumatic actuator. The first drive assembly 43 is connected to the multiple water inlet baffles 42 via a third transmission assembly 9. The third transmission assembly 9 includes a fourth transmission rod 91 and multiple fifth transmission rods 92. One end of the fourth transmission rod 91 is connected to the first drive assembly 43, and the other end is connected to the multiple fifth transmission rods 92. The other ends of the multiple fifth transmission rods 92 are respectively connected to the multiple water inlet baffles 42. When the first drive assembly 43 pushes the fourth transmission rod 91 along the second direction X2, the fourth transmission rod 91 can simultaneously drive multiple fifth transmission rods 92 to move along the second direction X2, thereby driving multiple inlet baffles 42 to move along the second direction X2. The position of the inlet baffles 42 changes, thus changing the opening and closing degree of the water inlet. The structure is simple and easy to set up. Of course, other methods can also be used to change the position of multiple inlet baffles 42, such as setting multiple first drive assemblies 43 respectively, and using multiple first drive assemblies 43 to directly connect with multiple inlet baffles 42 to directly drive the multiple inlet baffles 42 to move.

[0043] Combination Figure 2 , Figure 3As shown, the detection component 5 is mounted on the frame 1. The detection component 5 includes a detection plate 51 that contacts the surface of the steel strip 10 to be cleaned. The steel strip 10 can cause the detection plate 51 to move. Specifically, when the surface of the steel strip 10 is less contaminated, i.e., when there is less attached dirt, the friction between the detection plate 51 and the surface of the steel strip 10 is small, and the movement of the steel strip 10 can only cause a small displacement of the detection plate 51. When the surface of the steel strip 10 is more contaminated, i.e., when there is more attached dirt, the friction between the detection plate 51 and the surface of the steel strip 10 increases, and the movement of the steel strip 10 can cause a large displacement of the detection plate 51. Furthermore, friction protrusions are provided on the side of the detection plate 51 facing the surface of the steel strip 10, which improves the response sensitivity of the detection plate 51. The control component is coupled to the detection component 5 and the first drive component 43 (this coupling includes electrical and signal connections). The control component can control the first drive component 43 to drive the water inlet baffle 42 to move according to the displacement distance of the detection plate 51, so as to change the opening and closing degree of the water inlet.

[0044] Therefore, the cleaning device provided in this embodiment cleans the surface of the steel strip 10 by setting a cleaning assembly 4 including multiple cleaning components 41 between the unwinding roller 2 and the winding roller 3, passing the steel strip 10 to be cleaned between the two water spray pipes 411 of the cleaning assembly 41, and spraying cleaning water flow towards the upper and lower sides of the steel strip 10 by the two water spray pipes 411. In addition, a water inlet baffle 42 is set at the water inlet of the cleaning assembly 41, and a first drive assembly 43 is set to drive the water inlet baffle 42 to move. Furthermore, a detection assembly 5 including a detection plate 51 and a control assembly coupled to the detection assembly 5 and the first drive assembly 43 are also provided. The control assembly is configured to control the first drive assembly 43 to drive the water inlet baffle 42 to move according to the displacement distance of the detection plate 51, so as to change the opening and closing degree of the water inlet. With the above settings, when the displacement distance of the detection plate 51 is short, it indicates that the friction between the detection plate 51 and the surface of the steel strip 10 is small, and the degree of dirt on the surface of the steel strip 10 is low. At this time, the control component can control the water inlet baffle 42 to move, so that the water inlet has a smaller opening, thereby reducing the water spray volume of the spray pipe 411 and avoiding waste of water and energy. When the displacement distance of the detection plate 51 is long, it indicates that the friction between the detection plate 51 and the surface of the steel strip 10 is large, and the degree of dirt on the surface of the steel strip 10 is high. At this time, the control component controls the water inlet baffle 42 to move, so that the water inlet has a larger opening, thereby increasing the water spray volume of the spray pipe 411 and ensuring the cleaning effect on the surface of the steel strip 10. In the process of cleaning the surface of the steel strip 10 using the above cleaning device, adaptive cleaning of the surface of the steel strip 10 can be achieved according to the degree of dirt on the surface of the steel strip 10, ensuring cleaning quality and reducing cleaning costs.

[0045] In some embodiments, combined with Figures 3 to 6 As shown, the detection assembly 5 also includes a hollow component 52, a push rod 53, a first elastic element 54, and a displacement sensor 55. The hollow component 52 is mounted on the frame and may be, for example, a hollow plate or a hollow cylinder. The push rod 53 is inserted inside the hollow component 52. The first elastic element 54 is disposed inside the hollow component 52, and its two ends are connected to the inner wall of the hollow component 52 and the end of the push rod 53, respectively. The first elastic element 54 may be, for example, a cylindrical spring. The first elastic element 54 can use its elastic force to reset the detection plate 51. It is easy to understand that the elastic force of the first elastic element 54 should be set according to actual usage requirements (or according to the actual degree of dirt on the surface of the steel strip 10), which will not be described in detail here. The detection plate 51 is connected to the other end of the push rod 53. The detection plate 51 extends along a third direction X3, and one end of the detection plate 51 passes through the frame 1 and can slide along the first direction X1. The displacement sensor 55 is mounted on the frame 1 and is positioned directly opposite the end of the detection plate 51 in the first direction X1. This displacement sensor 55 is used to detect the displacement of the detection plate 51 in the first direction X1 and is coupled to the control component. The displacement sensor 55 can be, for example, a Hall effect sensor (with a magnetic induction element provided at the end of the detection plate 51) or a laser displacement sensor. With this configuration, the displacement distance of the detection plate 51 can be detected, resulting in a simple and convenient structure.

[0046] In some embodiments, such as Figure 5 The cleaning device further includes a second drive assembly 6 and a speed reduction assembly 7. The second drive assembly 6 is connected to the unwinding roller 2 and drives it to rotate, thus replacing manual rotation and saving manpower. The speed reduction assembly 7 is positioned opposite the output shaft 61 of the second drive assembly 6 and is connected to the first drive assembly 43. The speed reduction assembly 7 includes multiple friction blocks 71. The control assembly controls the first drive assembly 43 to move the multiple friction blocks 71 closer to the output shaft 61 based on the displacement distance of the detection plate 51, so that the friction blocks 71 abut against the output shaft 61. This configuration allows the speed reduction assembly 7 to decelerate the output shaft 61 of the second drive assembly 6, thereby slowing down the conveying speed of the steel strip 10 to be cleaned. This increases the water spray volume while extending the cleaning time of the steel strip 10, ensuring effective cleaning.

[0047] For example, combined Figure 5 , Figure 7As shown, the cleaning device also includes a support frame, on which the second drive assembly 6 is mounted. The deceleration assembly 7 further includes a first support plate 72, a second support plate 73, multiple second elastic elements 74, and a first transmission assembly 75. The first support plate 72 is connected to the support frame, its surface perpendicular to the first direction X1 and parallel to the second direction X2. The second support plate 73 is connected to the support frame and is arranged parallel to the first support plate 72. The second support plate 73 and the first support plate 72 are located on opposite sides of the output shaft 61 of the second drive assembly 6, and multiple friction blocks 71 are arranged along the extension direction of the output shaft 61. The multiple friction blocks 71 are located between the output shaft 61 and the second support plate 73. One end of each second elastic element 74 is connected to the first support plate 72, and the other end is connected to the friction block 71. The first drive assembly 43 is connected to the multiple friction blocks 71 via the first transmission assembly 75.

[0048] Furthermore, such as Figure 7As shown, the first transmission assembly 75 includes a second transmission rod 753 and multiple first transmission rods 751. Each of the multiple first transmission rods 751 includes a connecting end and a sensing end. The connecting end of the first transmission rod 751 is connected to the friction block 71, and the sensing end is provided with a first magnetic sensing element 752. The multiple sensing ends are arranged along the second direction X2. One end of the second transmission rod 753 is connected to the first drive assembly 43, which can drive the second transmission rod 753 to move along the second direction X2. The other end of the second transmission rod 753 is provided with a second magnetic sensing element 754, which can drive the first magnetic sensing element 752 to move towards the output shaft 61. It is easy to understand that when the first drive assembly 43 drives the second transmission rod 753 to move along the second direction X2, since multiple sensing ends (or multiple first magnetic sensing elements 752) are arranged along the second direction X2, the second magnetic sensing element 754 can sequentially approach the multiple first magnetic sensing elements 752, thereby sequentially driving the multiple first magnetic sensing elements 752 to move towards the output shaft 61. In this way, under the transmission action of the first transmission rod 751, different numbers of friction blocks 71 can abut against the output shaft 61 of the second drive assembly 6. For example, the sensing ends of the multiple first transmission rods 751 are arranged from top to bottom, and the second transmission rod 753 moves from top to bottom. During the movement, the second magnetic sensing element 754 first approaches the first magnetic sensing element 752 located above, driving the first magnetic sensing element 752 towards the output shaft 61. The second transmission rod 753 moves downward, causing the corresponding friction block 71 to abut against the output shaft 61; the second transmission rod 753 continues to move downward, and the second magnetic induction element 754 will approach the first magnetic induction element 752 located in the middle position, driving the first magnetic induction element 752 to move towards the output shaft 61, causing the corresponding friction block 71 to abut against the output shaft 61. At this time, the friction between the deceleration assembly 7 and the output shaft 61 increases, and the deceleration effect on the output shaft 61 increases; the second transmission rod 753 continues to move downward, and the second magnetic induction element 754 will approach the first magnetic induction element 752 located below, driving the first magnetic induction element 752 to move towards the output shaft 61, causing the corresponding friction block 71 to abut against the output shaft 61. At this time, the friction between the deceleration assembly 7 and the output shaft 61 further increases, and the deceleration effect on the output shaft 61 further increases.

[0049] With the above configuration, the second transmission rod 753 can be driven to move in the second direction X2 by the first drive assembly 43, thereby reducing the speed of the output shaft 61 of the second drive assembly 6 by the deceleration assembly 7. Simultaneously, the deceleration effect of the deceleration assembly 7 can be controlled by controlling the distance the second transmission rod 753 moves in the second direction X2. Furthermore, the movement of the second transmission rod 753 driven by the first drive assembly 43 can be synchronized with the movement of the water inlet baffle 42. That is, when the first drive assembly 43 drives the water inlet baffle 42 to adjust the water spray volume, it can simultaneously drive the second transmission rod 753 to adjust the deceleration effect, further ensuring the cleaning effect on the steel belt 10.

[0050] In some embodiments, combined with Figure 8 , Figure 9 As shown, the cleaning device also includes a filter assembly 8 located below the cleaning component 41. The filter assembly 8 includes a first filter plate 81 and a second filter plate 82, which are spaced apart along a second direction X2. Both the first filter plate 81 and the second filter plate 82 have multiple first filter holes. This arrangement allows the filter assembly 8 to filter the cleaned wastewater, facilitating reuse and saving costs.

[0051] Furthermore, such as Figure 9 As shown, the filter assembly 8 further includes a third filter plate 83, which is located between the first filter plate 81 and the second filter plate 82. The third filter plate 83 has multiple second filter holes, each corresponding to a different first filter hole. The filter assembly 8 also includes a second transmission assembly 84. The third filter plate 83 is connected to the reduction assembly 7 via the second transmission assembly 84. The friction block 71 abuts against the output shaft 61 and can drive the third filter plate 83 to reciprocate in the first direction X1 via the second transmission assembly 84. With this arrangement, during the reciprocating motion of the third filter plate 83, the alternating shearing force generated by the first and second filter holes can be used to cut and peel off the clumps of impurities that have formed in the filter holes, preventing the filter assembly 8 from becoming clogged. An arc-shaped cutter can also be provided in the second filter hole to further improve the cutting effect on the clumps of impurities.

[0052] Regarding the specific manner in which the friction block 71 abuts against the output shaft 61, enabling the third filter plate 83 to reciprocate in the first direction X1 via the second transmission assembly 84, an example is as follows: Figure 10As shown, a mounting notch 711 is provided on the friction block 71. The aforementioned second transmission assembly 84 includes a first rotating shaft, a transmission wheel 841, a first transmission gear 842, a third support plate 843, a second rotating shaft, a second transmission gear 844, and a third transmission rod 846. The first rotating shaft is rotatably mounted on the mounting notch 711. The transmission wheel 841 is sleeved on the first rotating shaft, and is configured such that when the side of the friction block 71 facing the output shaft 61 abuts against the outer peripheral surface of the output shaft 61, the transmission wheel 841 can also abut against the outer peripheral surface of the output shaft 61. The first transmission gear 842 is sleeved on the first rotating shaft. The third support plate 843 is disposed on the upper side of the friction block 71. The second rotating shaft rotatably passes through the third support plate 843, the second transmission gear 844 is disposed at one end of the second rotating shaft, and an eccentric transmission member 845 is disposed at the other end of the second rotating shaft. The second transmission gear 844 meshes with the first transmission gear 842. One end of the third transmission rod 846 is connected to the eccentric transmission component 845, and the other end is connected to the third filter plate 83. The eccentric transmission component 845 is configured such that rotating the eccentric transmission component 845 can drive the third transmission rod 846 to reciprocate in the first direction X1. The eccentric transmission component 845 is, for example, an eccentric wheel or a concentric wheel, with an inclined abutment portion or an eccentrically arranged abutment rod, abutment block, or other components on the wheel surface. With the above configuration, the friction block 71 can abut against the output shaft 61, and the third filter plate 83 can be driven to reciprocate in the first direction X1 via the second transmission assembly 84. Of course, other methods can also be used to achieve the above functions. For example, a transmission wheel 841 is provided on the side of the friction block 71. When the friction block 71 abuts against the output shaft 61, the transmission wheel 841 can also contact the output shaft 61. In this way, the output shaft 61 can drive the transmission wheel 841 to rotate. Furthermore, a rotating connection part is eccentrically provided on the side of the transmission shaft away from the friction block 71. One end of the third transmission rod 846 is rotatably connected to the rotating connection part, and the other end is rotatably connected to the third filter plate 83. In this way, when the transmission wheel 841 rotates, it drives the rotating connection part to make an eccentric movement. One end of the third transmission rod 846 connected to the transmission wheel 841 makes a circular motion, and the other end makes a reciprocating motion in the first direction X1.

[0053] In some embodiments, the cleaning device further includes two tension rollers. The two tension rollers are arranged parallel to each other and spaced apart. Both tension rollers are located between the unwinding roller 2 and the take-up roller 3. The cleaning assembly 4 is located between the two tension rollers. In the first direction X1, the two tension rollers and the cleaning assembly 4 are directly opposite each other. With this arrangement, when cleaning the steel strip 10, the two tension rollers can be used to tension and guide the steel strip 10, ensuring that the steel strip 10 passes correctly through the cleaning assembly 4, thus improving the practicality of the cleaning device.
