[0018] 3. This type of surface defect detection equipment, when the detection installation chamber passes from the top of the cleaning installation chamber, the bottom of the detection protection plate contacts the outside of the cleaning roller brush, and when the detection installation chamber continues to move, the cleaning roller brush can wipe and clean the outside of the detection protection plate. When the detection installation chamber moves, the cleaning roller brush can also be driven to rotate by the transmission rack. When the cleaning roller brush rotates, the roller brush scraper can scratch and clean the carbon ash adhered to the outside of the cleaning roller brush, and the cleaned carbon ash falls into the inside of the cleaning installation chamber, thereby preventing too much carbon ash adhered to the outside of the cleaning roller brush from affecting the cleaning effect on the outside of the detection protection plate.

When the rolled steel feeding roller 8 rotates, it can drive the rolled steel to move on the rolled steel feeding roller 8. When the transmission mechanism 5 rotates, it can drive the detection mechanism 6 to move synchronously. When the detection mechanism 6 moves, it can detect defects on the surface of the rolled steel on the rolled steel feeding roller 8. When the transmission mechanism 5 drives the detection mechanism 6 to move, the bottom of the detection mechanism 6 contacts the carbon ash cleaning mechanism 7, and the carbon ash cleaning mechanism 7 can clean the bottom of the detection mechanism 6.

[0024] During operation, the driving motor 2 drives the driving gear 3 to rotate, which can drive the transmission mechanism 5 to rotate through the motor transmission chain 4. When the transmission mechanism 5 rotates, it can drive the rolled steel feeding roller 8 to rotate through the rolled steel transmission gear 9. When the rolled steel feeding roller 8 rotates, it can drive the rolled steel to move along the surface of the rolled steel feeding roller 8. When the transmission mechanism 5 rotates, it can also drive the detection mechanism 6 to move synchronously, so that the detection mechanism 6 and the rolled steel on the surface of the rolled steel feeding roller 8 move synchronously. When the detection mechanism 6 moves, the defects of the rolled steel surface on the rolled steel feeding roller 8 can be detected. When the transmission mechanism 5 drives the detection mechanism 6 to move from above the carbon ash cleaning mechanism 7, the bottom of the detection mechanism 6 can contact the carbon ash cleaning mechanism 7. At this time, the carbon ash cleaning mechanism 7 can clean the bottom of the detection mechanism 6, and the rolled steel on the rolled steel feeding roller 8 and the detection mechanism 6 are driven to move synchronously through the transmission mechanism 5. When the detection mechanism 6 and the rolled steel on the rolled steel feeding roller 8 move synchronously, the detection mechanism 6 can perform visual identification detection on the surface of the rolled steel feeding roller 8, thereby ensuring the clarity of the image during the detection process.

[0026] The first transfer gear set 56 and the second transfer gear 57 are connected to each other through a transfer transmission chain 58. The outside of the first transfer gear set 56 is connected to the drive motor 2 at the drive end of the support body 1 through the motor transmission chain 4. The outside of the transfer transmission chain 58 is connected to multiple rolling transmission gears 9. The outside of the transfer transmission chain 58 is connected to the first transmission gear 53 and the second transmission gear 54. The supporting body 1 can drive the first transfer gear set 56 to rotate through the driving motor 2 and the driving gear 3. When the first transfer gear set 56 rotates, it can drive the second transfer gear 57 to rotate through the transfer transmission chain 58. The transfer transmission chain 58 can rotate around the outside of the first transfer gear set 56 and the second transfer gear 57. When the transfer transmission chain 58 rotates, it can drive the steel rolling transmission gear 9, the first transmission gear 53 and the second transmission gear 54 to rotate.

[0027] The central axis of the first transmission roller 51 passes through the support body 1 and is connected to the first transmission gear 53. The central axis of the second transmission roller 52 passes through the support body 1 and is connected to the second transmission gear 54. The second transmission rollers 51 and 52 are connected through a detection transmission belt 55. When the first transmission gear 53 and the second transmission gear 54 rotate, they can drive the first transmission roller 51 and the second transmission roller 52 to rotate. When the first transmission roller 51 and the second transmission roller 52 rotate, they can drive the detection transmission belt 55 to rotate around the first transmission roller 51 and the second transmission roller 52. When the detection transmission belt 55 rotates, it can drive the detection mechanism 6 to move synchronously to detect defects on the surface of the rolled steel.

[0028] During operation, the support body 1 can drive the first transfer gear set 56 to rotate through the drive motor 2 and the drive gear 3. When the first transfer gear set 56 rotates, the second transfer gear 57 can be driven to rotate through the transfer transmission chain 58, so that the transfer transmission chain 58 can rotate around the outside of the first transfer gear set 56 and the second transfer gear 57. When the transfer transmission chain 58 rotates, it can drive the steel rolling transmission gear 9, the first transmission gear 53 and the second transmission gear 54 to rotate. When the steel rolling transmission gear 9 rotates, it can drive the steel rolling feeding roller 8 to rotate to move the steel rolling. When the first transmission gear 53 and the second transmission gear 54 rotate, it can drive the first transmission roller 51 and the second transmission roller 52 to rotate. The first transmission roller 51 and the second transmission roller 52 rotate, and the rotation of the first transmission roller 51 and the second transmission roller 52 can drive the detection transmission belt 55 to rotate around the first transmission roller 51 and the second transmission roller 52. When the detection transmission belt 55 rotates around the first transmission roller 51 and the second transmission roller 52, it can drive the detection mechanism 6 to move synchronously to detect defects on the surface of the rolled steel. The rotation of the transit transmission chain 58 synchronously drives the rolled steel transmission gear 9 and the detection transmission belt 55 to rotate, so that the rolled steel and the detection mechanism 6 can move synchronously inside the support body 1. When the detection mechanism 6 and the rolled steel move synchronously, the detection mechanism 6 performs visual inspection on the surface of the rolled steel, which can prevent the detection image from being offset, thereby ensuring the clarity of the image during the detection process.

[0029] Example 3: The difference from the above embodiment is that, please refer to Figure 1 - Figure 12The detection mechanism 6 includes a fixed mounting seat 61, which is installed on the outside of the detection transmission belt 55. The outside of the fixed mounting seat 61 is rotatably connected with a rotating sliding groove 62, and the inside of the rotating sliding groove 62 is installed with a buffer spring 63. The inside of the rotating sliding groove 62 is installed with a connecting slider 64, and the outside of the connecting slider 64 is connected to a detection mounting shaft 65. The outside of the detection mounting shaft 65 is installed with a detection mounting bin 66, and the outside of the detection mounting bin 66 is installed with a transmission rack 67. The inside of the detection mounting bin 66 is installed with a detection sensor 68, and the inside of the detection mounting bin 66 is installed with a detection protective plate 69.

[0030] The two ends of the detection installation shaft 65 are slidably installed in the rotating sliding groove 62 through the connecting slider 64. The outer portion of the connecting slider 64 is connected to the inner portion of the rotating sliding groove 62 through the buffer spring 63. The two ends of the detection installation shaft 65 are rotatably connected to the fixed mounting seat 61 through the rotating sliding groove 62. The detection installation shaft 65 can move up and down inside the rotating sliding groove 62 through the connecting slider 64. When the detection transmission belt 55 drives the fixed installation seat 61 to move, the detection installation chamber 66 can be driven to move synchronously through the detection installation shaft 65.

[0031] The outside of the detection installation bin 66 is connected to the outside of the carbon ash cleaning mechanism 7 through a transmission rack 67; When the detection installation bin 66 moves, the detection sensor 68 can detect defects on the surface of the rolled steel through the detection protective plate 69. When the detection installation bin 66 passes above the carbon ash cleaning mechanism 7, the surface of the detection protective plate 69 can contact the outside of the carbon ash cleaning mechanism 7, and the carbon ash cleaning mechanism 7 can clean the surface of the detection protective plate 69.

[0032] During operation, the rotation of the detection transmission belt 55 can drive the fixed mounting seat 61 to move synchronously, and when the fixed mounting seat 61 moves, it can drive the detection mounting shaft 65 to move synchronously. When the detection mounting shaft 65 moves, it can drive the detection sensor 68 to move synchronously through the detection mounting bin 66. When the detection sensor 68 moves, it can perform visual inspection on the surface of the rolled steel through the detection protection plate 69. During the visual inspection process, some of the carbon ash floating around the rolled steel will adhere to the surface of the detection protection plate 69. When the detection transmission belt 55 drives the detection mounting bin 66 to move above the carbon ash cleaning mechanism 7, the detection protection plate 69 can contact the outside of the carbon ash cleaning mechanism 7. When the detection protection plate 69 contacts the carbon ash cleaning mechanism 7, the detection mounting shaft 65 can move up and down through the inside of the rotating sliding groove 62. After the detection protection plate 69 contacts the outside of the carbon ash cleaning mechanism 7, the carbon ash cleaning mechanism 7 continues to move to clean the carbon ash attached to the outside of the detection protection plate 69, thereby preventing the detection sensor 68 from affecting the detection result when the carbon ash on the outside of the detection protection plate 69 is subsequently visually inspected.

[0033] Example 4: The difference from the above embodiment is that, please refer to Figure 1 - Figure 12 The carbon ash cleaning mechanism 7 includes a cleaning installation chamber 71, which is installed inside the supporting body 1. A plurality of cleaning roller brushes 72 are installed inside the cleaning installation chamber 71. The outsides of the plurality of cleaning roller brushes 72 are all connected to roller brush transmission gears 73. A plurality of roller brush scrapers 74 are installed inside the cleaning installation chamber 71. The plurality of roller brush scrapers 74 correspond to the plurality of cleaning roller brushes 72 , and the outer portions of the roller brush scrapers 74 are in contact with the outer portions of the cleaning roller brushes 72 .

[0034] The central axis of the cleaning roller brush 72 passes through the side wall of the cleaning installation chamber 71 and is connected to the roller brush transmission gear 73. The detection installation chamber 66 is connected to the roller brush transmission gears 73 at both ends of the cleaning roller brush 72 through the external transmission rack 67. When the detection mounting chamber 66 passes through the top of the cleaning mounting chamber 71, the cleaning roller brush 72 can clean the surface of the detection protective plate 69. When the detection mounting chamber 66 moves, the cleaning roller brush 72 can be driven to rotate through the transmission connection between the transmission rack 67 and the roller brush transmission gear 73. When the cleaning roller brush 72 rotates, the outside of the cleaning roller brush 72 can be cleaned by contacting the roller brush scraper 74.

[0035] When the detection mounting chamber 66 passes from the top of the cleaning mounting chamber 71, the bottom of the detection protective plate 69 contacts the outside of the cleaning roller brush 72. When the detection mounting chamber 66 continues to move, the cleaning roller brush 72 can wipe and clean the outside of the detection protective plate 69. When the detection mounting chamber 66 moves, the cleaning roller brush 72 can also be driven to rotate through the transmission connection between the transmission rack 67 and the roller brush transmission gear 73. When the cleaning roller brush 72 rotates, the roller brush scraper 74 can scratch and clean the carbon ash adhered to the outside of the cleaning roller brush 72, and the cleaned carbon ash falls into the inside of the cleaning mounting chamber 71, thereby preventing too much carbon ash adhered to the outside of the cleaning roller brush 72 from affecting the cleaning effect on the outside of the detection protective plate 69.
