Technical Field
[0001] This invention belongs to the field of metal cutting technology, specifically relating to a metal strip slitting machine with online correction function. Background Technology
[0002] A metal strip slitting machine is a specialized metal cutting device used to divide wide metal strips into multiple narrow strips according to preset specifications. The metal strip is smoothly unwound by an unwinding device, and the guide rollers ensure stable transmission of the strip. Then, a high-speed rotating circular blade precisely cuts the strip to the set width. The slit narrow strips are neatly wound up by a winding device to form finished coils that meet the requirements. It is widely used in the steel, non-ferrous metal processing, electronics, and automotive industries. It features high precision, high efficiency, and a high degree of automation, and can effectively meet the slitting needs of metal strips of different thicknesses and materials.
[0003] A metal strip slitting machine with online deviation correction function is a mechanical device that can monitor and automatically correct the lateral position deviation of the strip in real time during the metal strip slitting process. By detecting the position of the strip edge or center line through sensors, the deviation signal is fed back to the control system, which in turn drives the actuator (such as servo motor, cylinder, etc.) to adjust the lateral position of the unwinding or rewinding shaft, ensuring that the strip always runs along the preset path, avoiding problems such as inconsistent slitting width and material damage caused by deviation, and improving slitting accuracy and product quality.
[0004] In metal strip slitting operations, burrs are generated on the cut edges of the strip after slitting due to the cutting force. These burrs not only significantly increase the surface roughness of the strip edge, but may also cause deviations in the actual width or thickness of the strip. Existing technology usually uses grinding rollers to treat the burrs on the cut edges of the strip after slitting. However, if the strip segments deviate due to roller problems after slitting, the deviation will cause the contact between the strip edge and the grinding roller to deviate, resulting in over-grinding or under-grinding of the strip edge, leading to deviations in the width of the strip after slitting.
[0005] Therefore, the present invention provides a metal strip slitting machine with online correction function. Summary of the Invention

[0017] The beneficial effects of this invention are as follows:
[0018] 1. The metal strip slitting machine with online correction function described in this invention can flexibly adjust the spacing between two disc blades through an adjustment component, so that the entire device can meet the slitting requirements of strips with different widths without replacing equipment or making complex mechanical modifications, thus improving the versatility and production efficiency of the equipment.

[0020] 3. The metal strip slitting machine with online correction function described in this invention, through the scale assembly, allows for accurate determination of the strip width at both sides of the slitting metal strip by observing the distance between scale marker one and scale marker two when adjusting the scale of the disc blade. This width information can be quickly obtained by directly observing the scale on the scale plate surface. Combined with the width of the middle strip reflected by the distance between the two disc blades, the width of each strip segment after slitting can be quickly and accurately obtained based on the scale indicated by scale marker one and scale marker two.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0033] like Figures 1 to 9 As shown, the present invention provides a technical solution: a metal strip slitting machine with online correction function, including a cutting table 1, an unwinding mechanism 2 and a winding mechanism 3 fixedly installed on the upper two sides of the cutting table 1 respectively, a gantry frame 9 fixedly installed above the cutting table 1, two disc blades 4 arranged parallel between the unwinding mechanism 2 and the winding mechanism 3, an anti-deviation component above the cutting table 1, the anti-deviation component including two relatively movable correction rollers 15, the correction rollers 15 can restrict the deviation of the two ends of the strip before slitting by relative movement, an adjustment component above the disc blades 4, the adjustment component can adjust the distance between the two disc blades 4, an edge trimming component is provided on the inner side of the gantry frame 9, the edge trimming component includes a pair of rotating and movable abrasive rollers 7 and a pair of abrasive rollers 8, the abrasive rollers 7 and 8 can be adjusted to fit closely to the edge of the strip after slitting when they move, the abrasive rollers 7 and 8 can grind the burrs on the edge of the strip after slitting when they rotate;
[0034] The anti-deviation assembly also includes a laser displacement sensor and a PLC control system, both of which are installed on the front side of the correction roller 15.
[0035] During operation: First, the unwinding shaft filled with metal strip is installed on the unwinding mechanism 2, and multiple empty take-up shafts are placed at the take-up mechanism 3. Before metal cutting, the positions of the two alignment rollers 15 are adjusted according to the overall width of the metal strip using the anti-deviation assembly. The two alignment rollers 15 can move closer or further apart, so that when dealing with strips of different widths, the outer walls of the two alignment rollers 15 can closely adhere to the two uncut front ends of the metal strip during the cutting process. A high-precision laser is installed in front of the alignment rollers 15. The displacement sensor continuously monitors the edge position of the strip. The sensor converts the strip offset into an electrical signal and transmits it to the PLC control system. The PLC system calculates the correction requirement in real time based on the offset and dynamically adjusts the position of the correction roller 15. Through the online correction system, the two correction rollers 15 continuously restrict the two sides of the uncut front end of the strip during the rotation of the winding shaft, preventing deviation caused by uneven tension, equipment vibration or defects in the strip itself during traction. This corrects the offset of the two sides of the front end of the strip in real time, ensuring the accurate size of each strip segment after slitting.
[0036] Next, the spacing between the two disc blades 4 is flexibly adjusted using the adjustment component to adapt to the slitting requirements of strips of different widths. During the adjustment of the spacing between the disc blades 4, the two abrasive rollers 1 7 and the two abrasive rollers 2 8 move synchronously. In this way, no matter what width of strip is being slit, the two abrasive rollers 1 7 can always be in contact with the two sides of the middle strip after slitting, while the two abrasive rollers 2 8 are in contact with one side of the cut edge of the strip on both sides after slitting. This achieves synchronous adjustment of the positions of the disc blades 4 and the abrasive rollers 1 7 and 2 8. The abrasive rollers 1 7 and 2 8 can not only grind the burrs on the edge of the strip after slitting, but also prevent the strip from shifting position during the subsequent winding process.
[0037] After the position adjustment of the disc blade 4 is completed, the metal strip end on the outer wall of the unwinding mechanism 2 is pulled to the outer wall of the winding mechanism 3 and connected firmly with the traction device. Then, the drive structure outside the winding mechanism 3 is started, driving multiple winding shafts to rotate simultaneously, so that the metal strip is continuously cut while the winding shafts are winding. While the winding shafts are rotating to cut, the trimming component drives the two sanding rollers 7 and 8 to rotate, effectively grinding the burrs on the cut edges of each strip after cutting, thereby improving the quality of the metal strip.
[0038] Through the above embodiments, the spacing between the two disc blades 4 can be flexibly adjusted by the adjustment component, enabling the entire device to meet the strip cutting requirements of different widths without the need to replace equipment or make complex mechanical modifications, thus improving the versatility and production efficiency of the equipment. During the adjustment of the spacing between the disc blades 4, the adjustment component can simultaneously drive the two abrasive rollers 1 7 and 2 abrasive rollers 8 to move, ensuring that when facing strip cutting of different widths, abrasive roller 1 7 can always adhere to both sides of the middle strip after cutting, and abrasive rollers 2 8 can respectively adhere to one side of the cut edge of the strip on both sides after cutting. The synchronous adjustment of the position avoids problems such as the inability to grind or strip misalignment caused by the mismatch between the blade and the grinding roller, ensuring the coordination and stability of the slitting and grinding process. Through the trimming component, the two grinding rollers 7 and 8 rotate, which can effectively grind the burrs on the cut edges of each strip as it passes through. While grinding the burrs, grinding rollers 7 and 8 can also restrict the position of each strip after slitting, preventing the strip from shifting position during the subsequent winding process, thus improving the overall production quality.
[0039] like Figure 5 As shown, the correction assembly also includes a limiting inner groove seat 17, which is fixedly installed above the gantry 9. The correction rollers 15 are located on both sides of the strip. The bottom of each correction roller 15 is rotatably connected to an internal threaded slider 18. The internal threaded slider 18 is slidably connected to and adapted to the inner wall of the limiting inner groove seat 17. The inner wall of the limiting inner groove seat 17 is rotatably connected to a bidirectional screw 19. The two ends of the bidirectional screw 19 are threadedly connected to the inner walls of the two internal threaded sliders 18 respectively. A second drive motor 20 is fixedly installed on one side of the limiting inner groove seat 17. The output shaft of the second drive motor 20 is fixedly connected to one end of the bidirectional screw 19.
[0040] During operation: Start the drive motor 20, and its output shaft drives the bidirectional screw 19 to rotate on the inner wall of the limiting inner groove seat 17. Since the two ends of the bidirectional screw 19 are respectively threaded to the inner wall of the internal thread sliders 18 located at the bottom of the two straightening rollers 15 on both sides of the strip, under the thread action generated by the rotation of the bidirectional screw 19 and the sliding limiting action of the inner wall of the limiting inner groove seat 17, the two internal thread sliders 18 will move in a straight line along the bidirectional screw 19 towards or away from each other, thereby driving the two straightening rollers 15 to move synchronously, realizing the adjustment of the position of the straightening rollers 15, so that they can closely fit the two sides of the uncut front end of the metal strip during the slitting process, preventing the front end from shifting and ensuring the accurate size of each strip segment after slitting.
[0041] like Figures 3 to 4As shown, a drive motor 13 is fixedly installed on the side of the gantry frame 9. The output shaft of the drive motor 13 is fixedly connected to a polygonal rotating shaft 12. The polygonal rotating shaft 12 passes through the two gantry frames 9. The outer wall of the polygonal rotating shaft 12 is slidably connected to the inner wall of the disc blade 4 and they are mutually adapted.
[0042] During operation: When a slitting operation is required, the drive motor 13 is started, and its output shaft drives the polygonal rotating shaft 12 to rotate. Under the driving force generated by the rotation of the polygonal rotating shaft 12, the disc blade 4 will rotate around its own axis along with the polygonal rotating shaft 12, thereby realizing the slitting operation of the metal strip. At the same time, because the inner wall of the disc blade 4 is slidably adapted to the outer wall of the polygonal rotating shaft 12, when the adjustment component adjusts the distance between the two disc blades 4, the disc blade 4 can move smoothly along the axial direction of the polygonal rotating shaft 12 without affecting its normal rotation with the polygonal rotating shaft 12.
[0043] like Figures 3 to 4 As shown, the adjustment assembly includes two clamping housings 11, which are fixedly connected to the outer wall of the disc blade 4. An inner ring assembly 21 is fixedly connected to one side of each clamping housing 11. Telescopic rods 22 are symmetrically fixedly connected to the inner side wall of the gantry 9. The output ends of the telescopic rods 22 are fixedly connected to the outer wall of the inner ring assembly 21. A scale assembly is provided above the disc blade 4. The scale assembly can accurately reflect the width of each strip after slitting.
[0044] During operation: When it is necessary to adjust the spacing between the two disc blades 4 to meet the strip cutting requirements of different widths, the telescopic rod 22 is activated. The output shaft of the telescopic rod 22 begins to extend and retract. Under the push or pull of the output end of the telescopic rod 22, the inner ring assembly 21 will drive the clamping housing 11 and the disc blades 4 to move linearly along the axis of the polygonal rotating shaft 12. The two disc blades 4 will then move closer or further away from each other, thereby changing the position of the two disc blades 4 on the outer wall of the polygonal rotating shaft 12. During this process, the scale component set above the disc blades 4 can accurately reflect the width of each strip after cutting, making it convenient for operators to accurately control the spacing adjustment of the disc blades 4.
[0045] like Figures 3 to 5 As shown, the scale assembly includes a scale plate 10, which is fixedly connected to one side of the gantry 9. Scale markers 14 are fixedly connected to the sides of the clamping housing 11. The bottom of each scale marker 14 is slidably connected to the top of the scale plate 10, and the tip of each scale marker 14 corresponds to the scale strip on the surface of the scale plate 10.
[0046] During operation: When the telescopic rod 22 drives the disc blades 4 to adjust the spacing, the scale marker 14 will also move together, and its tip will point to different scale positions on the surface of the scale plate 10. These scales precisely correspond to the spacing between the two disc blades 4. At this time, the spacing between the two disc blades 4 is the width of the strip at the middle position after slitting. By observing the scale pointed to by the tip of the scale marker 14, the operator can directly obtain the current spacing of the disc blades 4 and the width information of the strip after slitting, and then accurately control the slitting size based on this information.
[0047] like Figure 3 and Figure 5 As shown, the top of the shaft of the correction roller 15 is fixedly connected with a scale mark 16, the bottom of the scale mark 16 is slidably connected to the surface of the scale plate 10, and the tip of the scale mark 16 corresponds to the scale strip on the surface of the scale plate 10.
[0048] During operation: Before the slitting process begins, the positions of the two alignment rollers 15 must be precisely adjusted using the anti-deviation assembly to ensure that the alignment rollers 15 are tightly fitted to both sides of the unslit metal strip. When the alignment rollers 15 move, they will simultaneously drive the scale markers 16 to slide along the surface of the scale plate 10. As the position of the alignment rollers 15 changes, the scale value pointed to by the tip of the scale markers 16 will also change accordingly. At this time, the scale values pointed to by the two scale markers 16 can be set as the starting scale and the ending scale, respectively, and the distance between them is the width of the entire unslit metal strip. Subsequent adjustments... During the process of spacing the disc blades 4, by observing the spacing between the first scale mark 14 and the second scale mark 16, the width of the strip located on both sides of the metal strip after being cut can be accurately determined. Moreover, this width information can be quickly obtained by directly observing the scale on the surface of the scale plate 10. At the same time, the spacing between the two disc blades 4 can reflect the width of the strip located in the middle position after being cut. In this way, the width of each strip after cutting can be quickly and accurately obtained according to the scales pointed to by the first scale mark 14 and the second scale mark 16 on the surface of the scale plate 10.
[0049] In the above embodiment, by adjusting the scale of the disc blade 4 through the scale assembly, the distance between the scale marker 14 and the scale marker 16 can be observed to accurately determine the width of the strip at both sides of the metal strip after slitting. This width information can be quickly obtained by directly observing the scale on the surface of the scale plate 10. Combined with the width of the middle strip reflected by the distance between the two disc blades 4, the width of each strip after slitting can be quickly and accurately obtained according to the scale indicated by the scale marker 14 and the scale marker 16. This allows operators to quickly and accurately grasp the slitting dimensions, achieve precise control and real-time monitoring of the slitting dimensions, improve the efficiency and quality of the slitting operation, and provide a guarantee for the production of metal strip slitting.
[0050] like Figures 1 to 2 As shown, guide rod 5 and guide rod 6 are symmetrically rotatably connected between the inner walls of the gantry frame 9. Both guide rod 5 and guide rod 6 can be wound around the outer wall of the metal strip.
[0051] During operation: The metal strip is continuously slit while being wound up by the take-up shaft. The slit strips are then continuously guided by guide rod 5 and guide rod 6 and are wound up crosswise by the various take-up shafts. This also provides suitable operating space for abrasive roller 7 and abrasive roller 8 so that they can deburr the edges of the corresponding strips.
[0052] like Figures 7 to 9 As shown, the trimming assembly includes two servo motors 29. The output shafts of the servo motors 29 are fixedly connected to one end of the shaft of the first abrasive roller 7. The other end of the first abrasive roller 7 is fixedly connected to a worm gear 27. The shaft of the second abrasive roller 8 is fixedly connected to a worm wheel 28. The threads of the worm gear 27 and the threads of the worm wheel 28 are always meshed with each other.
[0053] During operation: As the take-up shaft rotates, the metal strip is continuously cut by the disc blade 4. Simultaneously, the servo motor 29 is activated, and its output shaft drives two abrasive rollers 7 to rotate simultaneously. The two abrasive rollers 7 are now in close contact with the two edges of the strip located in the middle position after cutting. As the two abrasive rollers 7 rotate, they can polish the two edges of the strip at this position. Meanwhile, the two abrasive rollers 8 are in contact with one edge of the cut section of the strip on both sides. When the abrasive roller 7 rotates, the meshing relationship between the worm gear 27 and the worm wheel 28 also enables the two abrasive rollers 8 to rotate synchronously. This ensures that the edges of each section of strip can be effectively polished. By comprehensively polishing the two edges of the strip after cutting and the edges of the cut section, burrs, flash, and other defects can be effectively removed, making the strip edges smoother and flatter, improving the overall quality of the metal strip, and meeting higher production standards.
[0054] like Figures 6 to 9As shown, servo motors 29 are fixedly installed in the inner wall of the inner ring assembly 21. The outer walls of the shafts of the first grinding roller 7 are symmetrically connected to slide blocks 25. The outer walls of the shafts of the second grinding roller 8 are symmetrically connected to sliders 24. Multi-directional connectors 30 are fixedly connected between sliders 24 and slide blocks 25 at the shafts of adjacent first grinding roller 7 and second grinding roller 8.
[0055] During operation: When the telescopic rod 22 pushes or pulls the inner ring assembly 21 to change the position of the disc blade 4, it also drives the servo motor 29 to move, so that the two abrasive rollers 7 and the two disc blades 4 maintain the same movement process. Thus, when the disc blade 4 adjusts its position to change the width of the slit strip, the position of the abrasive rollers 7 also changes accordingly. The two abrasive rollers 7 can also closely adhere to the two sides of the strip at the middle position after slitting. The abrasive rollers 7 will also drive the abrasive rollers 8 to move synchronously through the multi-directional connector 30, so that the two abrasive rollers 8 can respectively adhere to one side of the cut edge of the strip at both sides after slitting. In this way, no matter how the disc blade 4 adjusts its position to adapt to the slitting requirements of different width strips, the abrasive rollers 7 and 8 can be accurately positioned to achieve efficient and precise grinding of each edge of the slit strip.
[0056] like Figures 7 to 9 As shown, two sliders 26 and two slide blocks 23 are fixedly installed on the inner side of the gantry frame 9. Slide blocks 25 are slidably connected to the inner wall of sliders 26, and sliders 24 are slidably connected to the inner wall of slide blocks 23.
[0057] During operation: Slide 25 slides along the inner wall of slider 26, providing guidance for the movement of abrasive roller 7, ensuring that abrasive roller 7 can move accurately in the predetermined direction and always closely adhere to the two edges of the strip located in the middle position after slitting, thereby achieving effective grinding of the strip edges; Slider 24 slides along the inner wall of slide 23, providing guidance for the movement of abrasive roller 8, so that abrasive roller 8 can accurately adhere to one edge of the strip located at the cut point on both sides after slitting, ensuring the accuracy and stability of grinding the edges of the strip on both sides.
[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
