[0022] Example 1: In some embodiments, please refer to Figures 1-9, a continuous strip steel surface quality inspection device, including a frame 1, and also including: an upper and lower limit conveying mechanism 2, a front and rear limit conveying mechanism 3, a detection mechanism 4, a continuous cleaning mechanism 5 and a winding and unwinding mechanism 6, multiple upper and lower limit conveying mechanisms 2 are fixedly installed on the frame 1, multiple front and rear limit conveying mechanisms 3 are installed on the frame 1, a short bracket 7 is fixedly installed on the right side of the middle of the frame 1, two of the detection mechanisms 4 are installed on the short bracket 7, a long bracket 8 is fixedly installed on the left side of the middle of the frame 1, two of the continuous cleaning mechanisms 5 are installed on the long bracket 8, the winding and unwinding mechanism 6 is installed on the frame 1, the continuous The cleaning mechanism 5 includes: a cross bar 51, a guide rail 52, a slider 53, a sliding plate 54 and a cylinder 55. The cross bar 51 is fixedly mounted on the long bracket 8. A first strip opening 56 is opened on the middle side of the cross bar 51. The guide rail 52 is fixedly mounted on the cross bar 51. The slider 53 is slidably connected to the guide rail 52. The sliding plate 54 is fixedly mounted on the slider 53. The two cylinders 55 are respectively fixedly mounted on the front and rear sides of the cross bar 51. The output ends of the cylinders 55 are both facing the center direction of the frame 1. The continuous cleaning mechanism 5 also includes: a height-adjustable dust suction component, which is mounted on the sliding plate 54.

[0023] The upper and lower limit conveying mechanisms 2 assist in conveying the strip with upper and lower position limits, the front and rear limit conveying mechanisms 3 assist in conveying the strip with front and rear position limits, the continuous cleaning mechanism 5 continuously cleans both surfaces of the continuously conveyed strip, the detection mechanism 4 detects surface defects on the cleaned strip, and the reeling and unreeling mechanism 6 reels and unreels the strip.

[0024] The sliding plate 54 of the continuous cleaning mechanism 5 is placed at the output end of one of the cylinders 55. The output end of the cylinder 55 extends and contacts the sliding plate 54. The sliding plate 54 is pushed to the output end of the other cylinder 55. The output end of the other cylinder 55 extends and pushes the sliding plate 54, so that the sliding plate 54 moves back and forth repeatedly under the limit of the guide rail 52 and the slider 53.

[0025] The height-adjustable dust collection assembly includes: a clamping block 57, a suction pipe 58, a rotating block 59, a connecting pipe 510 and a bellows 511. The two clamping blocks 57 are fixedly mounted on the sliding plate 54, the suction pipe 58 is fixedly mounted between the two clamping blocks 57, the rotating block 59 is rotatably connected to the long bracket 8, the connecting pipe 510 is fixedly mounted on the rotating block 59, one end of the bellows 511 is fixedly connected to the suction pipe 58, and the end of the bellows 511 away from the suction pipe 58 is fixedly connected to the connecting pipe 510.

[0026] The end of the connecting pipe 510 away from the bellows 511 is connected to the external dust collection equipment, unscrew the clamping block 57, adjust the upper and lower heights of the suction pipe 58 of the height-adjustable dust collection assembly, so that the suction pipe 58 is located at a preset position on the surface of the strip, tighten the clamping block 57 to fix the suction pipe 58, and the sliding plate 54 moves back and forth repeatedly to drive the clamping block 57 to move back and forth. The movement of the clamping block 57 back and forth drives the suction pipe 58 to move back and forth. The movement of the suction pipe 58 back and forth continuously absorbs the dust on the upper and lower surfaces of the strip. Since the suction pipe 58 moves back and forth, the adsorption force on the surface of the strip is larger and uniform, which is conducive to the suction and cleaning of dust on the surface of the strip.

[0027] The front and rear movement of the suction pipe 58 drives the bellows 511 to move back and forth, and the front and rear movement of the bellows 511 drives the connecting pipe 510 to rotate back and forth. The rotating block 59 assists the connecting pipe 510 to rotate back and forth, preventing the bellows 511 from being damaged due to long-term front and rear movement.

[0028] The height-adjustable dust collection assembly also includes: a buffer assembly, multiple buffer assemblies are installed on the long bracket 8, and the buffer assembly includes: a sliding bracket 512, an adjusting screw 513, a fixing nut 514 and a tension spring 515.

[0029] The sliding plate 54 moves back and forth to the position of the sliding bracket 512, driving the sliding bracket 512 to move away from the center position of the frame 1. The movement of the sliding bracket 512 away from the center position of the frame 1 causes the tension spring 515 to be elastically deformed and stretched, so that the sliding plate 54 stops when it moves to the output end position of the cylinder 55, and the sliding plate 54 does not hit the output end of the cylinder 55. By loosening the fixing nut 514 and moving the adjusting screw 513 back and forth, the tension of the tension spring 515 can be adjusted, so that the sliding plate 54 stops moving when it moves to the output end of the cylinder 55. At this time, the output end of the cylinder 55 extends to push the sliding plate 54, which is conducive to quickly buffering the forward and backward movement of the sliding plate 54.
