[0044] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0045] As Figure 1 shown, according to the first aspect of the embodiments of the present disclosure, a strip steel detection device is proposed, including: a first guide rail 100 for being arranged on the frame of the air knife device 900; a detection assembly 200 movably arranged on the first guide rail 100, the detection assembly 200 having a detection end for being arranged facing the strip steel to be detected, and the detection assembly 200 being used for detecting the distance information between the detection end and the strip steel to be detected; a control assembly for controlling the distance of the detection assembly 200 moving along the first guide rail 100; wherein, the extending direction of the first guide rail 100 is the same as the extending direction of the air knife moving track of the air knife device 900.

[0046] The strip steel detection device proposed by the embodiments of the present disclosure includes: a first guide rail 100, a detection assembly 200 and a control assembly. The first guide rail 100 is arranged on the frame of the air knife device 900, and the extending direction of the first guide rail 100 is the same as the air knife moving track of the air knife device 900. The detection assembly 200 is movably arranged on the first guide rail 100. The first guide rail 100 can provide a stable and accurate track for the movement of the detection assembly 200, thereby ensuring that the moving direction of the detection device is consistent with the moving direction of the air knife on the air knife device 900. At the same time, the detection end of the detection assembly 200 is arranged facing the strip steel to be detected, so as to facilitate the detection assembly 200 to detect the distance information between the detection end and the strip steel. In practical applications, the air knife can be moved first. When the air knife reaches the preset position, the operator can adjust the position of the detection assembly 200 through the control assembly so that the position of the detection end corresponds to the position of the air knife. At this time, the distance information between the detection end and the strip steel is detected through the detection assembly 200. Through this distance information, the position state between the strip steel and the air knife can be judged. If the distance information is normal, it indicates that the strip steel is in a position suitable for processing by the air knife. If the distance information is abnormal, it indicates that the position of the strip steel does not match the position of the air knife, and further adjustment of the position of the strip steel or the air knife position is required.

[0047] It can be understood that before the detection, the relative positions of the detection end and the air knife need to be determined. The distance between the detection end and the air knife can be adjusted during installation, or the distance between the detection end and the air knife can be adjusted before the air knife moves. After the air knife moves, the moving distance of the detection device can be adjusted according to the moving distance of the air knife to ensure that the distance between the detection end detected by the detection component 200 and the strip can accurately reflect the distance between the air knife and the strip surface.

[0048] It can be understood that when the detection component 200 reaches the position of the detection end, the position of the above detection end corresponds to the position of the air knife. The air knife and the detection end can be located in the same plane parallel to the strip surface, so that the distance information detected by the detection component 200 is equal to the distance between the air knife and the strip. Or there may be a fixed distance difference between the distance from the air knife to the strip surface and the distance from the detection end to the strip surface. The distance between the air knife and the strip is the distance information detected by the detection component 200 minus this distance difference. For example, if the distance from the detection end to the strip surface is 5 mm larger than the distance from the air knife to the strip surface, the distance between the air knife and the strip is the distance information detected by the detection component 200 minus 5 mm.

[0049] It can be understood that the detection component 200 and the air knife are separately arranged, which can prevent interference between the detection component 200 and the air knife. Even when the air knife operates subsequently, it will not affect the position of the detection component 200, which is beneficial to improving and ensuring the accuracy of the detection.

[0050] It should be noted that encoders are installed on air knife devices 900 in the industry. Currently, for the distance between the air knife and the strip, feedback is often carried out through the encoder, and the position of the air knife is adjusted according to the feedback result. However, the encoder can only judge the distance between the air knife and the strip based on the theoretical position of the strip. If the rolling line of the strip deviates and the distance between the strip and the air knife changes, the encoder cannot identify it, so it is impossible to ensure that the distance between the air knife and the strip is in a situation suitable for the air knife device 900 to process, which is not conducive to ensuring the production quality. Compared with the prior art, the strip detection device proposed in the embodiments of the present disclosure can accurately judge the distance relationship between the air knife and the strip based on the foregoing settings, so as to ensure that the distance between the air knife and the strip is in a state suitable for the air knife device 900 to process, which is beneficial to improving the production quality of the strip galvanized layer.

[0051] Exemplarily, the detection component 200 can be installed above the air knife.

[0052] In some examples, such as Figure 1As shown in the figure, the control component includes: a driving part 310 for providing a driving force for the detection component 200 to move the detection component 200 along the first guide rail 100; a control part signal-connected to the driving part 310; wherein, the control part is used for receiving the air knife movement information transmitted by the air knife device 900 and controlling the driving force output by the driving part 310 according to the air knife movement information.

[0053] In the above technical solution, the control component includes a driving part 310 and a control part. Among them, the control part can receive the air knife movement information of the air knife device 900 and control the driving part 310 through the air knife movement information. By controlling the driving force of the driving part 310, the control part can control the moving distance of the detection component 200 along the first guide rail 100. In this way, the control part can automatically adjust the position of the detection component 200 according to the air knife movement situation, so that the position of the detection component 200 can quickly correspond to the position of the air knife, which can not only improve the detection efficiency but also improve the detection accuracy.

[0054] Exemplarily, the first guide rail 100 adopts a ball screw, and the driving part 310 adopts a cylinder.

[0055] In some examples, as Figure 1 shown, the detection component 200 includes: a sliding part 210 slidably arranged on the first guide rail 100, and the sliding part 210 has a second guide rail 211; a detection piece 220 slidably arranged on the second guide rail 211, and a detection end is formed on the detection piece 220. The detection piece 220 is used for detecting distance information; wherein, the extending direction of the second guide rail 211 is the same as the length direction of the air knife.

[0056] In the above technical solution, the detection component 200 includes a sliding part 210 and a detection piece 220. The sliding part 210 is slidably arranged on the first guide rail 100, and the detection component 200 is slidably arranged on the second guide rail 211 of the sliding part 210. And the extending direction of the second guide rail 211 is the same as the length direction of the air knife. Thus, when detecting the distance between the strip steel and the detection end through the detection end of the detection piece 220, by adjusting the position of the detection piece 220 on the second guide rail 211, it is possible to detect the distance between each position in the length direction of the air knife and the strip steel, which can not only improve the detection efficiency but also improve the detection accuracy.

[0057] Exemplarily, the detection piece 220 adopts an electromagnetic sensor.

[0058] In some examples, as Figure 1 shown, the sliding part 210 further includes: a sliding frame 212 slidably arranged on the first guide rail 100, and the sliding frame 212 is located at both ends of the second guide rail 211.

[0059] In the above technical solution, the sliding part 210 further includes a sliding frame 212. The sliding frame 212 is arranged at both ends of the second guide rail 211. The second guide rail 211 is slidably arranged on the first guide rail 100 through the sliding frame 212. On the one hand, the arrangement of the sliding frame 212 can form a frame structure, which is beneficial to improving the stability of the second guide rail 211 and facilitating the stable setting of the detection piece 220. On the other hand, the sliding frame 212 is arranged at both ends of the second guide rail 211, which can also leave enough space for the detection piece 220, making it convenient for the detection piece 220 to slide and for the operator to observe the position of the detection piece 220.

[0060] In some examples, such as Figure 1 shown, the detection assembly 200 further includes: a driving part 230, connected to the detection piece 220 and used to provide a driving force for the detection piece 220.

[0061] In the above technical solution, the detection assembly 200 further includes a driving part 230. The driving part 230 is connected to the detection piece 220, and the driving part 230 can provide a driving force for the detection piece 220, so that the detection piece 220 slides along the second guide rail 211. Sliding through the driving part 230 is beneficial to improving the stability and accuracy of the sliding.

[0062] Exemplarily, the driving part 230 can adopt a servo motor.

[0063] In some examples, such as Figure 1 shown, the driving part 230 is signal-connected to the control assembly, and the control assembly is used to control the driving force output by the driving part 230.

[0064] In the above technical solution, the driving part 230 is signal-connected to the control assembly. The control assembly can control the moving position of the detection piece 220 on the second guide rail 211 by controlling the driving force output by the driving part 230, that is, the control assembly can not only control the movement of the detection piece 220 in the extending direction of the air knife moving track, but also control the movement of the detection piece 220 in the length direction of the air knife, so as to realize that the control assembly can control the detection piece 220 to complete the full-process control of the distance detection between the air knife and the strip steel, which can not only improve the operation convenience, but also further improve the stability and production efficiency of the production line.

[0065] It can be understood that the control assembly has an operation interface. The operator only needs to input specific parameter instructions on the operation interface of the control assembly to accurately set the moving track and detection position of the detection piece 220, so that the detection piece 220 can comprehensively and efficiently detect the distance between the air knife and the strip steel through a suitable moving path.

[0066] In some examples, such as Figure 1As shown, it further includes: a drag chain 400, which is arranged on the detection member 220 and is used to protect the cable connected to the detection member 220.

[0067] In the above technical solution, the strip steel detection device further includes a drag chain 400. The drag chain 400 is arranged on the detection member 220. Since as the detection member 220 slides, the cable connected to the detection member 220 will also move and be pulled, the setting of the drag chain 400 can protect the cable connected to the detection member 220, avoid the situation of cable breakage, and is beneficial to ensuring the stable operation of the strip steel detection device.

[0068] In some examples, as Figure 1 shown, it further includes: a display component, which is signal-connected to the detection member 220 and is used to receive and display distance information; wherein, the display component is preset with a distance threshold range, and in the case where the distance information exceeds the distance threshold range, the display component specially displays the distance information that exceeds the distance threshold range.

[0069] In the above technical solution, the strip steel detection device further includes a display component. The display component is connected to the detection member 220. The distance information detected by the detection member 220 can be sent to the display component, and the display component can display the distance information and will specially display the distance information that exceeds the distance threshold range; thus, it is convenient for the operator to identify problem data, so as to facilitate the operator to further adjust the strip steel or the air knife.

[0070] It can be understood that the display component has a function module and a display module. The function module can process the received distance information and display it through the display module.

[0071] Exemplarily, the display component can share a display with the air knife device 900 for convenient data observation.

[0072] In some examples, as Figure 1 shown, the control component is adapted to be signal-connected to the operation module and the display module of the air knife device 900.

[0073] In the above technical solution, the control component is signal-connected to the operation module and the display module of the air knife device 900. Thus, on the operation interface of the air knife device 900, the movement of the strip steel detection device can be displayed and operated, so as to control the movement of the detection component 200 of the strip steel detection device according to the movement data of the air knife.

[0074] According to the second aspect of the embodiments of the present disclosure, an air knife processing system is proposed, including: an air knife device 900; the strip steel detection device as described in any one of the above first aspects.
