[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes an adjustable guide device, including a base 1. Two slide rails are fixedly installed on the top of the base 1, and two slide tables 3 are slidably installed on the two slide rails. A guide assembly 5 is fixedly installed on the top of each slide table 3. The limiting structure of the guide assembly 5 consists of a support plate 51, longitudinal limiting plates 53, and a pressing plate 55. Two longitudinal limiting plates 53 are fixedly installed on the top of the support plate 51, and the pressing plate 55 is movably installed on the two matching longitudinal limiting plates 53. This double-plate limiting structure improves the stability of the pressing plate 55 during lifting and lowering adjustment. By adjusting the guide assembly 5 laterally, it can meet the limiting and guiding requirements of strips of different widths. By adjusting the height of the pressing plate 55, the distance between the pressing plate 55 and the support plate 51 can be easily adjusted, which can meet the requirements for limiting and guiding strips of different thicknesses. The top of the base 1 is fixedly installed with a detection bracket 2, which is equipped with a first line array camera 23 and a second line array camera 25. It can detect the width and thickness of the strip before it enters the guide assembly 5, and transmit the detection data to the control cabinet. The control cabinet controls the servo motor 6 and the hydraulic cylinder 54 to enter the working state, which facilitates the adjustment of the distance between the guide assemblies 5 and the distance between the pressing plate 55 and the support plate 51 without manual intervention, thus improving processing efficiency.

[0029] like Figures 1-3As shown, in order to facilitate clamping and limiting of strips of different widths, a support plate 51 is fixedly installed on the top of a matching slide table 3. A servo motor 6 is fixedly installed on the top of the base 1, and a reciprocating screw 4 is fixedly installed at the output end of the servo motor 6. A slider 31 and a connecting plate 32 are fixedly installed on the lower surface of the support plate 51. One end of the reciprocating screw 4 passes through the matching connecting plate 32 and is threadedly connected to it. The slider 31 is slidably installed on the matching slide rail. The servo motor 6 drives the reciprocating screw 4 to rotate, which in turn drives the slide table 3 to move laterally along the guide rail. This facilitates the horizontal adjustment of the two guide components 5 and can meet the limiting and guiding requirements of strips of different widths.

[0030] Furthermore, to facilitate clamping and limiting of strip steel of different thicknesses, two elongated openings 551 are cut into the pressing plate 55. The top of each longitudinal limiting plate 53 passes through the matching elongated opening 551 and is movably connected to it, ensuring that the pressing plate 55 can be stably erected above the support plate 51. A hydraulic cylinder 54 is fixedly installed on the top of each of the two longitudinal limiting plates 53 in the same group. The output end of the hydraulic cylinder 54 is fixedly connected to the pressing plate 55. The hydraulic cylinder 54 drives the pressing plate 55 to lift and adjust, which facilitates the adjustment of the distance between the pressing plate 55 and the support plate 51, and can meet the limiting and guiding requirements of strip steel of different thicknesses.

[0031] Secondly, in order to reduce the wear on the support plate 51 and the pressure plate 55, several steel rollers 52 are rotatably installed on both the support plate 51 and the pressure plate 55. When the strip enters the area between the support plate 51 and the pressure plate 55, the steel rollers 52 rotatably installed on the support plate 51 provide support for the strip. At this time, the steel rollers 52 rotatably installed on the pressure plate 55 press against the upper surface of the strip. During the process of pushing the strip into the mill inlet, the steel rollers 52 can prevent the strip from making direct contact with the support plate 51 and the pressure plate 55. This can reduce the wear on the support plate 51 and the pressure plate 55 when the strip is pushed forward, and effectively reduce the wear of the guide device.

[0032] like Figure 1 and Figure 4 As shown, in order to facilitate the pre-detection of the strip width, two support frames 21 constituting the detection bracket 2 are fixedly installed on the top of the base 1. A tray 22 is fixedly installed on the top of the two support frames 21. Several first line scan cameras 23 are assembled on the tray 22. When the strip passes through the detection bracket 2, the images of the upper surface of the strip are captured by the multiple first line scan cameras 23. The images are combined with the image processing algorithm to identify the two sides of the upper surface of the strip, calculate the pixel distance and convert it into the actual width, so as to facilitate the pre-detection of the strip width.

[0033] Furthermore, to facilitate the pre-detection of the strip thickness, several second line array cameras 25 are fixedly installed on the support frame 21. When the strip passes through the detection bracket 2, the images of the strip side are captured by the multiple second line array cameras 25. The images are then combined with image processing algorithms to identify the two edges of the strip side, calculate the pixel distance, and convert it into the actual thickness, thus facilitating the pre-detection of the strip thickness.

[0034] Secondly, in order to ensure that the strip can pass through the inspection bracket 2 smoothly, an overlap plate 24 is fixedly installed between the two support frames 21. The overlap plate 24 provides support for the strip and ensures that the strip can pass through the inspection bracket 2 smoothly.

[0035] In this embodiment, the strip steel is first supported by the overlapping plate 24 to ensure that the strip steel can pass through the detection bracket 2. During the process of the strip steel passing through the detection bracket 2, the width of the strip steel is pre-detected by the first line scan camera 23, and the detection data is transmitted to the control cabinet. The control cabinet controls the servo motor 6 to enter the working state. During the process of the servo motor 6 driving the reciprocating screw 4 to rotate, the distance between the two guide components 5 can be adjusted to ensure that the distance between the two guide components 5 meets the width requirements of the strip steel. This not only limits the horizontal direction of the strip steel, but also ensures that the strip steel passes through the guide components 5. The thickness of the strip steel is detected by the second line scan camera 25. When the control cabinet receives the thickness data, it can control the hydraulic cylinder 54 to enter the working state. At this time, the hydraulic cylinder 54 drives the pressing plate 55 to move up and down to ensure that the distance between the pressing plate 55 and the support plate 51 meets the thickness requirements of the strip steel. This then limits the vertical direction of the strip steel and ensures the stability of the strip steel guidance. The pre-detection method and automatic adjustment of the guide components 5 do not require manual intervention and can improve processing efficiency.

[0036] During the process of the strip passing through the guide assembly 5, the steel rollers 52 rotatably mounted on the support plate 51 can provide stable support for the strip. The steel rollers 52 rotatably mounted on the pressure plate 55 can press and limit the top of the strip. During the process of the strip being pushed forward, the steel rollers 52 can improve the smoothness of its movement and prevent the strip from directly contacting the support plate 51 and the pressure plate 55, thus reducing the wear caused to the support plate 51 and the pressure plate 55 and effectively reducing the wear on the guide device. Combined with the automatic adjustment function of the guide assembly 5, it can meet the guidance requirements of different strips and effectively improve the applicability of the guide device.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
