DETAILED DESCRIPTION
[0026] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The specific operation is as follows: the material roll body 3 is attached to the surface of the lower pressure-feeding conveyor belt 2, and the material roll body 3 is located between the extended crawler tracks 4, and then the hydraulic push rod 6 extends to make the upper pressure-feeding conveyor belt 1 descend to press on the surface of the material roll body 3, and the two sets of lower pressure-feeding conveyor belts 2 and upper pressure-feeding conveyor belts 1 are synchronously driven to make the material roll body 3 be transmitted in one direction. During the transmission process, the material roll body 3 passes through the middle of the body box 501, so that the detection window 502 of the body box 501 is located above and below the material roll body 3. The infrared light and its reflected light must pass through the detection window 502 to be received by the detector inside the body box 501, and then the signal processing system processes the electrical signal and displays it through the display screen. As shown, the micro motor 503 periodically drives the first screw rod 504 to rotate so that the wiping sleeve 505 slides against the surface of the detection window 502, thereby allowing the wiping sleeve 505 to regularly wipe and clean the surface of the detection window 502, thereby preventing dust from adhering to the surface of the detection window 502 and causing misdetection. In addition, since the material roll body 3 is clamped by the upper pressure conveyor belt 1 and the lower pressure conveyor belt 2 after being tightened, the material roll body 3 is ensured to be transported smoothly and the material roll body 3 is prevented from shaking slightly during transportation, thereby avoiding misdetection of defects, which is beneficial to ensuring and improving the accuracy of the results of surface defect detection of the material roll body 3.
[0029] like Figure 1-Figure 5As shown, a defect marking component 7 is fixed inside the outer side of the extension track 4, and the defect marking component 7 includes a micro push rod 701 and a short rack 702, and the micro push rod 701 is evenly distributed inside the extension track 4, and the short rack 702 is fixed on the outer end of the micro push rod 701. The defect marking component 7 also includes a transmission rack 703, a spring telescopic rod 704 and a synchronous bracket 705. A transmission rack 703 is arranged above the short rack 702, and the end of the transmission rack 703 is connected to the spring telescopic rod 704, and the outer wall of the movable rod of the spring telescopic rod 704 is fixed with a synchronous bracket 705. The defect marking component 7 also includes a drive motor 706, and the drive motor 706 is fixed to one side of the top of the synchronous bracket 705. The defect marking component 7 also includes a second screw 707, and the output end of the drive motor 706 A second screw rod 707 is connected, the defect marking component 7 also includes a guide rail 708, the outer wall of the second screw rod 707 is connected to the guide rail 708 through a movable sleeve, and the guide rail 708 and the second screw rod 707 are vertically distributed, the defect marking component 7 also includes an electric telescopic push rod 709, one end of the guide rail 708 is fixed with the electric telescopic push rod 709, and the movable rod part of the electric telescopic push rod 709 is penetrated into the inside of the guide rail 708, the defect marking component 7 also includes a sliding inkjet bar 710, the inside of the guide rail 708 is slidably connected with the sliding inkjet bar 710, and the sliding inkjet bar 710 is connected to the ink pump body through a pipeline, the bottom of the sliding inkjet bar 710 is equidistantly distributed with spray holes, and the top of the sliding inkjet bar 710 is fixedly connected to the movable rod end of the electric telescopic push rod 709;
[0030] The specific operation is as follows: when the system background detects that there is a defect on the surface of the roll body 3 based on the received electrical signal, the defect position will be recorded. When the defect position on the surface of the roll body 3 is transmitted to the bottom of the sliding inkjet bar 710, the micro push rod 701 on the side extends to make the short rack 702 mesh with the transmission rack 703, and then the transmission rack 703 moves synchronously under the transmission action of the extension track 4 to compress the spring telescopic rod 704, so that the sliding inkjet bar 710 moves together with the synchronous bracket 705 and the movable rod of the spring telescopic rod 704. At this time, the sliding inkjet bar 710 and the defect position on the surface of the roll body 3 move relatively still, so that the nozzle at the bottom of the sliding inkjet bar 710 can spray ink to the defect position on the surface of the roll body 3 to highlight the defective part, so that the subsequent slitting machine can avoid the defective position when shearing the roll body 3;
[0031] When the sliding inkjet bar 710 and the defective position on the surface of the material roll body 3 are relatively stationary and move synchronously, the driving motor 706 drives the second screw 707 to rotate so that the sliding inkjet bar 710 can slide back and forth along the X-axis direction. At the same time, the sliding inkjet bar 710 slides back and forth inside the guide rail 708 through the extension and retraction of the electric telescopic push rod 709, that is, the sliding inkjet bar 710 slides back and forth along the Y-axis direction, thereby allowing the nozzles at the bottom of the sliding inkjet bar 710 to further adjust their positions so that the nozzles can be further aligned with the defective parts on the surface of the material roll body 3. Moreover, the sliding inkjet bar 710 moves synchronously with the defective positions on the surface of the material roll body 3, providing sufficient time for further adjustment of the nozzle positions, and also providing sufficient time for data transmission delays, thereby avoiding the material roll body 3 being transmitted too fast, resulting in errors and misalignments in the defective part markings.
[0032] A slitting machine is provided with the above-mentioned metal coil defect detection device.
[0033] In summary, when the metal coil defect detection device and the slitting machine are used, first the coil body 3 is attached to the surface of the lower pressure conveyor belt 2, and the coil body 3 is located between the extension tracks 4, and then the hydraulic push rod 6 is extended to make the upper pressure conveyor belt 1 descend to press on the surface of the coil body 3, and the two groups of lower pressure conveyor belts 2 and upper pressure conveyor belts 1 are synchronously driven to make the coil body 3 be transmitted in one direction, and the coil body 3 passes through the middle of the body box 501 during the transmission process, so that the detection window 502 of the body box 501 is located above and below the coil body 3, and the infrared light and its reflected light must pass through the detection window 502 to be received by the detector inside the body box 501, and then the electrical signal is processed by the signal processing system and displayed on the display screen, wherein the periodic micro motor 503 will drive the first screw rod 504 to rotate so that the wiping sleeve 505 is attached to the surface of the detection window 502 and slides, so that the wiping sleeve 505 can regularly wipe and clean the surface of the detection window 502;
[0034] When the system background detects that there is a defect on the surface of the roll body 3 based on the received electrical signal, the defect position will be recorded. When the defect position on the surface of the roll body 3 is transmitted to the bottom of the sliding inkjet bar 710, the micro push rod 701 on the side extends to make the short rack 702 mesh with the transmission rack 703, and then the transmission rack 703 moves synchronously under the transmission action of the extended track 4 so that the spring telescopic rod 704 is compressed, so that the sliding inkjet bar 710 moves together with the synchronous bracket 705 and the movable rod of the spring telescopic rod 704. At this time, the sliding inkjet bar 710 and the defect position on the surface of the roll body 3 move relatively still, so that the nozzle at the bottom of the sliding inkjet bar 710 can spray ink to the defect position on the surface of the roll body 3 to highlight the defective part;
[0035] When the sliding inkjet strip 710 and the defective position on the surface of the material roll body 3 are relatively stationary and move synchronously, the driving motor 706 drives the second screw 707 to rotate so that the sliding inkjet strip 710 can slide back and forth along the X-axis direction. At the same time, the sliding inkjet strip 710 can slide back and forth along the inside of the guide rail 708 through the extension and retraction of the electric telescopic push rod 709, that is, the sliding inkjet strip 710 slides back and forth along the Y-axis direction, thereby allowing the nozzle at the bottom of the sliding inkjet strip 710 to further adjust its position so that the nozzle can be further aligned with the defective position on the surface of the material roll body 3.
