[0002] The continuous annealing production line consists of a feeding unit, a cleaning unit, a shearing unit, and the main structure of the annealing furnace. In normal production, the surface of the strip steel after cleaning by the cleaning unit can only be judged by observation to determine the cleaning effect, which involves a great deal of uncertainty in the judgment of cleaning quality. Utility Model Content

[0003] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of this disclosure provides a quality sampling device for the cleaning section of a continuous annealing production line, comprising a main beam, a displacement mechanism, and a sampling assembly. The main beam is disposed above the outlet of the cleaning section of the continuous annealing production line. The displacement mechanism is slidably connected to the main beam along its extension direction. The sampling assembly includes an operating rod, a connecting shaft, a sampling element, and a sampling element support rod. The connecting shaft is connected to the displacement mechanism. The operating rod and the sampling element operating rod are connected to the connecting shaft. The sampling element is connected to the end of the sampling element support rod. The operating rod is used to drive the sampling element support rod to rotate circumferentially around the connecting shaft so that the sampling element moves toward the surface of the strip. The sampling element has a sampling filter paper mounting position facing the surface of the strip.

[0005] In one feasible implementation, the extension direction of the main beam is perpendicular to the strip steel.

[0006] In one feasible implementation, the sampling element includes a sampling element body and a fixing element, the fixing element being disposed on the side opposite to the sampling filter paper mounting position, and the fixing element being used to fix the filter paper to the sampling filter paper mounting position.

[0007] In one feasible implementation, the sampling body is configured as a cylinder, and the extending direction of the sampling body is consistent with the extending direction of the strip steel.

[0008] In one feasible implementation, a sleeve is further included, which is slidably connected along the extension direction of the connecting shaft, and the operating rod is connected to the sampling element support rod via the sleeve.

[0009] In one feasible implementation, the displacement mechanism includes a first plate, a second plate, and a pulley. The first plate and the second plate are disposed on both sides of the main beam, and the pulley is connected between the first plate and the second plate, and the pulley is slidably connected to the main beam.

[0010] In one feasible implementation, the sampling element can rotate horizontally in the circumferential direction along the end of the sampling element support rod, and the sampling element is detachably connected to the sampling element support rod.

[0011] In one feasible implementation, the operating lever forms an angle with the sampling support rod, and the angle is set to 100 degrees to 135 degrees.

[0012] In one feasible embodiment, an adjusting member is further included, the adjusting member being connected to the connecting shaft, the operating rod being connected to the sampling component support rod, and the adjusting member being used to adjust the included angle formed by the operating rod and the sampling component support rod.

[0013] A second aspect of this disclosure provides a continuous annealing production line, including the aforementioned quality sampling device for the cleaning section of the continuous annealing production line.

[0014] Compared with the prior art, this disclosure has at least the following beneficial effects: The main beam of this disclosure is set above the cleaning section outlet of the continuous annealing production line. The displacement mechanism is slidably connected to the main beam along the extension direction of the main beam to drive the sampling mechanism to sample in the width and / or length direction of the strip. The operating rod and the sampling element operating rod are connected to the connecting shaft to form a linkage structure. The sampling element is connected to the end of the sampling element support rod. When the operating rod swings circumferentially along the connecting shaft, the operating rod can drive the sampling element support rod to rotate circumferentially around the connecting shaft so that the sampling element moves toward the surface of the strip and the sampling filter paper mounting position faces the surface of the strip and contacts the strip for sampling. When the operating rod pushes or pulls back, it can also drive the displacement mechanism to move in the extension direction of the strip and the sampling element moves in the width and / or extension direction of the strip. At this time, the sampling element performs regional sampling. The wiping sampling of the strip surface of this disclosure can more intuitively judge the cleaning quality of the strip.

[0026] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0028] Currently, continuous annealing production lines consist of a feeding unit, a cleaning unit, a shearing unit, and the main structure of the annealing furnace. In normal production, the cleaning quality of the strip steel surface after cleaning by the cleaning unit can only be judged by observation, which introduces a great deal of uncertainty in the determination of cleaning quality.

[0029] Based on this, this disclosure provides a quality sampling device for the cleaning section of a continuous annealing production line. The main beam of this disclosure is located above the outlet of the cleaning section of the continuous annealing production line. The displacement mechanism is slidably connected to the main beam along its extension direction to drive the sampling mechanism to sample in the width and / or length direction of the strip. The operating rod and the sampling component operating rod are connected to the connecting shaft to form a linkage structure. The sampling component is connected to the end of the sampling component support rod. When the operating rod swings circumferentially along the connecting shaft, it can drive the sampling component support rod to rotate circumferentially around the connecting shaft so that the sampling component moves toward the surface of the strip and the sampling filter paper mounting position faces the surface of the strip and contacts the strip for sampling. When the operating rod pushes or pulls back, it can also drive the displacement mechanism to move in the extension direction of the strip and the sampling component moves in the width and / or extension direction of the strip. At this time, the sampling component performs regional sampling. The wiping sampling of the strip surface of this disclosure can more intuitively judge the cleaning quality of the strip.

[0030] The following is a detailed description of the quality sampling device for the cleaning section of the continuous annealing production line through specific embodiments:

[0031] Reference Figures 1 to 5 As shown, a first aspect of this disclosure provides a quality sampling device for the cleaning section of a continuous annealing production line, including a main beam 1, a displacement mechanism 2, and a sampling assembly 3. The main beam 1 is disposed above the outlet of the cleaning section of the continuous annealing production line. The displacement mechanism 2 is slidably connected to the main beam 1 along the extension direction of the main beam 1. The sampling assembly 3 includes an operating rod 31, a connecting shaft 32, a sampling element 33, and a sampling element support rod 34. The connecting shaft 32 is connected to the displacement mechanism 2. The operating rod 31 is connected to the connecting shaft 32. The sampling element 33 is connected to the end of the sampling element support rod 34. The operating rod 31 is used to drive the sampling element support rod 34 to rotate circumferentially around the connecting shaft 32 so that the sampling element 33 moves toward the surface of the strip steel 100. The sampling element 33 has a sampling filter paper mounting position facing the surface of the strip steel 100.

[0032] The main beam 1 of this disclosure is set above the cleaning section outlet of the continuous annealing production line. The displacement mechanism 2 is slidably connected to the main beam 1 along the extension direction of the main beam 1 to drive the sampling mechanism to sample in the width direction and / or length direction of the strip. The specific sampling in the width direction or length direction is determined according to the layout direction of the main beam 1. The operating lever 31 and the sampling element operating lever 34 are connected to the connecting shaft 32 to form a linkage structure. The sampling element 33 is connected to the end of the sampling element support rod 34. When the operating lever 31 swings around the connecting shaft 32, the operating lever 31 can drive the sampling element support rod 34 to rotate around the connecting shaft 32 so that the sampling element 33 moves toward the surface of the strip steel 100, and the sampling filter paper mounting position faces the surface of the strip steel 100 and contacts the strip steel 100 for sampling. When the operating lever 31 pushes or pulls back, it can also drive the displacement mechanism 2 to move in the extension direction of the strip steel 100, so that the sampling element 33 moves in the width direction and / or extension direction of the strip steel 100. At this time, the sampling element 33 performs regional sampling. The wiping sampling of the surface of the strip steel 100 disclosed in this invention can more intuitively judge the cleaning quality of the strip steel.

[0033] Specifically, according to the design requirements of the quality sampling device for the cleaning section of the continuous annealing production line, the layout and selection of the main beam 1 need to comprehensively consider factors such as the width of the strip 100, sampling accuracy, and installation environment. The layout can be either perpendicular to the strip 100 in the extension direction, covering the entire width, and fixed to the steel structure frame at the outlet of the cleaning section via columns; or a segmented combined structure wide-width production line using multi-segment flange connections for easy transportation and installation, with reinforcing ribs at the joints to prevent bending deformation. Both implementations can be equipped with height adjustment mechanisms (such as screw lifting devices) to increase adaptability to different application scenarios. Specifically, the structural profiles can be box beams, I-beams, or aluminum alloy beams. Considering the automated control of the displacement mechanism 2 and other expansion accessories (such as position sensors and laser rangefinders), the main beam 1 incorporates a cable drag chain groove and air pipe channel to conceal the power / signal lines of the sampling components. A laser rangefinder mounting position is reserved at the top for strip edge position detection.

[0034] The specific structural layout of the displacement mechanism 2 disclosed herein can be configured by setting linear guide rails on both sides of the main beam 1, or by integrating a rack into the main beam 1. The displacement mechanism 2 is driven by a servo motor and a reducer to move the gears. It should be noted that the displacement mechanism 2, as a supporting component of the sampling component 3, needs to be provided with an installation and supporting space for the sampling component, and the displacement mechanism 2 should also be provided with a manual drive mode, for example, by pushing and pulling the operating lever 31 to drive the displacement mechanism 2.

[0035] In some embodiments, the sampling member 33 includes a sampling member body 331 and a fixing member 332. The fixing member 332 is disposed on the side opposite to the sampling filter paper mounting position, and the fixing member 332 is used to fix the filter paper to the sampling filter paper mounting position.

[0036] In this embodiment, the fixing member 332 can be made of spring steel sheets symmetrically arranged on both sides of the sampling body 331, clamping the filter paper edge with an elastic pressure of 5-8mm to ensure the filter paper is flat and wrinkle-free; or a permanent magnet (such as neodymium iron boron) can be embedded around the sampling filter paper mounting position, and the fixing member 332 can be a detachable stainless steel pressure strip; or the fixing member 332 can be designed as a threaded cap, with an annular groove on the top of the sampling body 331, which presses the filter paper edge when rotated and locked. Furthermore, the height difference between the lower surface of the fixing member 332 and the bottom surface of the sampling body 331 is ≥3mm to ensure that the strip does not contact during fluctuations, and the edge of the fixing member 332 has a radius of R1.5mm to avoid scratching the strip.

[0037] In some embodiments, the sampling body 331 is configured as a cylinder, and the extending direction of the sampling body 331 is consistent with the extending direction of the strip 100.

[0038] In this embodiment, the cylindrical sampling body 331 is in parallel contact with the strip steel 100 to avoid scratching the surface. Furthermore, the contact position between the cylindrical sampling body 331 and the strip steel 100 is a line contact, which allows for better sampling during the pushing and pulling sampling process of the sampling member 33.

[0039] In some embodiments, the device further includes a sleeve 4, which is slidably connected along the extension direction of the connecting shaft 32, and the operating rod 31 and the sampling support rod 34 are connected to the sleeve 4.

[0040] In this embodiment, the sleeve 4 is slidably connected along the extension direction of the connecting shaft 32, thereby increasing the adjustment of the sampling member 33 in another direction. For example, when the extension direction of the main beam 1 is perpendicular to the extension direction of the strip 100, the extension direction of the connecting shaft 32 is consistent with the extension direction of the strip 100. Then, by setting the sleeve 3, the sampling member can sample in the width direction of the strip through the displacement mechanism 2, and can also sample in the extension direction of the strip 100 to a certain extent.

[0041] In some embodiments, the displacement mechanism 2 includes a first plate 21, a second plate 22 and a pulley 23. The first plate 21 and the second plate 22 are disposed on both sides of the main beam 1, and the pulley 23 is connected between the first plate 21 and the second plate 22, and the pulley 23 is slidably connected to the main beam 1.

[0042] In this embodiment, the first plate 21 and the second plate 22 are symmetrically arranged on both sides of the main beam 1, forming a stable frame structure that effectively resists deformation caused by strip vibration or lateral load. The double-plate design disperses stress, reduces the risk of unilateral wear, and extends service life. The pulley 23 engages with the guide rail of the main beam 1 through a V-groove or roller to achieve high-precision sliding, with a lateral positioning error ≤ ±0.1mm. Furthermore, pulleys with ceramic coatings or corrosion-resistant materials (such as 304 stainless steel) are used to adapt to the high humidity environment of the cleaning section. This embodiment comprehensively improves the rigidity, accuracy, and environmental adaptability of the displacement mechanism 2, and is particularly suitable for the high-frequency sampling requirements of continuous annealing production lines.

[0043] In some embodiments, the sampling member 33 can rotate horizontally in the circumferential direction along the end of the sampling member support rod 34, and the sampling member 33 is detachably connected to the sampling member support rod 34.

[0044] In this embodiment, the sampling member 33 can be rotated horizontally along the circumferential direction at the end of the sampling member support rod 34, which can adjust the sampling angle of the sampling member 33 relative to the strip 100, thereby increasing the number of samples collected. Furthermore, the sampling member support rod 34 is detachable for easy maintenance, and by replacing the sampling member 33 with a different size, a better strip size can be used.

[0045] In some embodiments, the operating lever 31 forms an angle with the sampling support rod 34, and the angle is set to 100 degrees to 135 degrees.

[0046] In this embodiment, the obtuse angle structure of 100 to 135 degrees ensures that the force applied by the operating rod 31 and the support rod 34 form the optimal force component ratio, reducing the torque required for manual operation by approximately 30%. An angle greater than 90 degrees avoids dead spots, ensuring that the sampling component 33 can be stably locked at any angle. Furthermore, the obtuse angle layout increases structural rigidity, controlling displacement deviation within ±0.5mm under strip vibration conditions (frequency ≤80Hz). The 135-degree extreme angle prevents the support rod 34 from obstructing the view, facilitating observation of the filter paper sampling status. This solution achieves a balance between mechanical performance, operational efficiency, and spatial compatibility through angle optimization, making it particularly suitable for high-frequency sampling scenarios in continuous annealing production lines.

[0047] In some embodiments, an adjusting member is also included. The adjusting member is connected to the connecting shaft 32, and the operating lever 31 and the sampler support rod 34 are connected to the adjusting member. The adjusting member is used to adjust the included angle formed by the operating lever 31 and the sampler support rod 34.

[0048] In this embodiment, the technical solution achieves dynamic adjustment of the angle between the operating rod 31 and the sampling support rod 34 through an adjusting component. The adjusting component disclosed herein can adopt a worm gear or threaded structure, achieving 1° precision angle locking to adapt to sampling depth requirements of strip steel of different thicknesses. Furthermore, the adjusting component incorporates damping material (such as polyurethane) to absorb 80% of high-frequency vibration energy (>50Hz). The above solution combines mechanical gain, environmental adaptability, and long-term durability, making it particularly suitable for continuous sampling scenarios of multi-specification strip steel 100.
