Abstract
Description
Technical Field

[0002] A straightening machine is a type of equipment widely used in the metal processing field. It is mainly used to straighten metal sheets, profiles or other materials. The straightening roller in the straightening machine is one of its core components, used to achieve precise straightening of materials.
[0003] During long-term use, the continuous contact between the straightening roller and the metal sheet causes uneven wear on the roller surface. Metal oxides generated in the high-temperature working environment are easy to adhere to the roller surface, leaving scratches on the surface of the straightened sheet and reducing the straightening effect.
[0004] The existing straightening roll grinding technology involves workers using handheld grinding tools to grind the surface of the straightening rolls. Especially for online maintenance, workers need to enter the straightening machine. This manual grinding is not only labor-intensive and time-consuming, but also creates a poor environment. The dust is harmful to human health, and the grinding accuracy is difficult to guarantee, which has a certain impact on the subsequent straightening quality. Moreover, it is very dangerous.

[0058] In this embodiment of the straightening roller inter-roller moving grinding device, the lighting lamp 35 and the industrial camera 31 are mounted on the working plate 29 near one end of the driven wheel 22. This arrangement allows the lighting lamp 35 and the industrial camera 31 to be closer to the straightening roller to be processed, improving the processing accuracy.
[0059] The working principle of the straightening roller inter-roller moving and grinding device in this embodiment is as follows:
[0060] When the straightening roller inter-roller moving and grinding device is working, the relevant parameters of the straightening machine are set in advance on the PC host computer 36, such as the number of straightening rollers, roller spacing, straightening roller diameter, straightening roller length, and straightening roller rolling speed. Then, the opening and closing height of the straightening rollers of the straightening machine is adjusted to the maximum, so that the straightening rollers on the straightening machine run at a low speed to facilitate the all-round inspection of the straightening rollers. The tray 5 starts from the starting point, and the two first X-axis sliders 12 are controlled by the PC host computer 36 to drive the Y-axis motion mechanism to move, so that the four limit grooves 6 in the tray 5 on the Y-axis motion mechanism are aligned with the surfaces of the first two lower straightening rollers 7. The Y-axis motor 8 on the Y-axis motion mechanism is controlled to move the tray 5 towards the straightening rollers and stop close to one side of the lower straightening rollers 7. The roller moving mechanism is controlled to stop smoothly on the two slowly running lower straightening rollers 7 through the limit grooves 6.
[0061] First, the lower straightening roller 7 is inspected and ground. The rotary driver 25 is controlled to make the Z-axis motion mechanism perpendicular to both the Y-axis motion mechanism and the lower straightening roller 7. The end of the work plate 29 with the industrial camera 31 is positioned downwards. The second X-axis slider 19 is controlled to move the Z-axis motion mechanism directly above the lower straightening roller 7 to be ground. The PC host computer 36 activates the lighting 35 and the industrial camera 31, and controls the roller movement mechanism to move slowly along the axis of the lower straightening roller 7. The roller movement mechanism moves a fixed distance each time, dividing the straightening roller into multiple sections for inspection. Upon reaching the first inspection section, the industrial camera 31 monitors and captures images of the roller surface of the lower straightening roller 7 in real time. The roller surface of one inspection section is divided into multiple fan-shaped areas for image capture. The host computer 36 detects the captured images and analyzes whether there are defects. If defects are found, the defect type is classified and the defect location is located. After all fan-shaped areas in the current detection zone have been detected, if a defective fan-shaped area exists, the straightener stops running when the fan-shaped area on the straightening roller is directly below the grinding machine. The Z-axis slider 28 is moved to drive the grinding machine to the designated position, and the sanding belt motor 32 on the grinding machine is started to drive the sanding belt 34 to grind the defective area. After grinding, the grinding machine is moved upward, and relevant grinding records are added to the host computer 36. Then, the straightener continues to run to the next defective area for grinding, and the Z-axis slider 28 is moved to drive the grinding machine to the designated position again. The grinding machine is started again for grinding, and all defective fan-shaped areas in the detection zone are ground in sequence. After the first detection zone is completed, the machine moves to the next detection zone for grinding, until the last area of a lower straightening roller 7 is detected.
[0062] Then, the upper straightening roller is inspected and ground. The second X-axis slider 19 is moved, simultaneously driving the Z-axis motion mechanism to move directly below the upper straightening roller to be ground, near the side of the roller-to-roller moving mechanism. The rotary driver 25 is controlled to make the end of the work plate 29 with the industrial camera 31 facing upwards. The lighting 35 and the industrial camera 31 are turned on, and the roller-to-roller moving mechanism is controlled to move from the last inspection area of the upper straightening roller to the first inspection area for inspection and grinding. After the first inspection area of the upper straightening roller is inspected, the roller-to-roller moving mechanism moves from the two lower straightening rollers 7 along the limiting groove 6 into the tray 5. The Y-axis slider 11 moves the tray 5 to the middle of the Y-axis guide rail 9. Then, the two first X-axis sliders 12 move the Y-axis guide rail 9 by the distance between the centers of two adjacent lower straightening rollers 7, so that the grinding machine can grind the next adjacent lower straightening roller 7 and upper straightening roller. The straightening roller roller-to-roller moving grinding device continues to operate as above to inspect and grind the subsequent straightening rollers.
[0063] For the grinding of the first two lower straightening rollers 7 and the lower straightening roller 7 between the two lower straightening rollers 7, the orientation of the roller moving mechanism on the tray 5 can be manually reversed to enter the third and fourth lower straightening rollers 7 in the opposite direction, and the second lower straightening roller 7 can be ground. After completion, return to the tray 5, and then enter the second and third lower straightening rollers 7 to grind the first lower straightening roller 7 and the upper straightening roller. After grinding all the straightening rollers, the roller moving mechanism returns to the tray 5, and the tray 5 is brought back to the starting point by the first X-axis slider 12 and the Y-axis slider 11.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
