[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a high-precision slitting and length-cutting device for steel coils, comprising a support frame 1, a support plate 2 fixedly connected to the upper surface of the support frame 1, a support platform 5 fixedly connected inside the support plate 2, a hydraulic cylinder 3 fixedly connected to the upper surface of the support frame 1, a connecting block 4 fixedly connected to the output end of the hydraulic cylinder 3, the outer wall of the connecting block 4 slidably connected to the inside of the support platform 5, a rack 6 fixedly connected to the upper surface of the connecting block 4, a gear 7 meshing with the tooth end of the rack 6, the outer wall of the gear 7 rotatably connected to the inside of the support platform 5, a sliding plate 8 fixedly connected to the outer wall of the rack 6, a limit strip 9 slidably connected inside the sliding plate 8, the lower surface of the limit strip 9 fixedly connected to the upper surface of the support platform 5, a limit rod 10 fixedly connected to the upper surface of the sliding plate 8, a fixed platform 11 slidably connected to the outer wall of the limit rod 10, the outer wall of the fixed platform 11 fixedly connected to the inside of the support plate 2, and a winding assembly provided inside the support frame 1 for winding the steel coil.
[0027] Specifically, the support frame 1 fixes the support plate 2, the support plate 2 fixes the support platform 5, and the support frame 1 fixes the hydraulic cylinder 3. Activating the hydraulic cylinder 3 causes the connecting block 4 to slide inside the support platform 5, which in turn causes the rack 6 to slide. The rack 6 then causes the sliding plate 8 to slide on the outer wall of the limiting strip 9, where the limiting strip 9 serves a limiting function. The sliding plate 8 causes the limiting rod 10 to slide on the outer wall of the fixed platform 11, which supports the steel coil body 22. The limiting rod 10 can center and clamp the steel coil body 22, thus achieving centering and preventing the steel coil body 22 from shifting during subsequent cutting, which would affect the accuracy of the cutting and slitting.
[0028] Reference Figure 1 and Figure 6 The winding assembly includes a motor 12, the outer wall of which is fixedly connected to the inside of the support frame 1. A winding wheel 13 is fixedly installed at the output end of the motor 12. A steel coil body 22 is installed on the outer wall of the winding wheel 13. The outer wall of the steel coil body 22 is slidably connected to the upper surface of the fixed platform 11.
[0029] Specifically, the support frame 1 fixes the motor 12. Starting the motor 12 can drive the winding wheel 13 to rotate. By setting the steel coil body 22 on the outer wall of the winding wheel 13, the steel coil body 22 can be driven to rotate, achieving the effect of integrated unwinding and winding.
[0030] Reference Figure 4 and Figure 5A vertical plate 14 is fixedly connected to the upper surface of the support frame 1. A second motor 15 is fixedly connected to the outer wall of the vertical plate 14. A rotating rod 16 is fixedly installed at the output end of the second motor 15. The outer wall of the rotating rod 16 is rotatably connected to the inside of the vertical plate 14. A fixing block 17 is slidably connected to the outer wall of the rotating rod 16. A cutting blade 18 is fixedly connected to the outer wall of the fixing block 17. A locking post 19 is slidably connected to the inside of the fixing block 17. The outer wall of the locking post 19 is slidably connected to the inside of the rotating rod 16. A sliding piece 20 is fixedly connected to the outer wall of the locking post 19. The outer wall of the sliding piece 20 is slidably connected to the inside of the fixing block 17. One end of a spring 21 is fixedly connected to the outer wall of the sliding piece 20. The other end of the spring 21 is fixedly connected to the inside of the fixing block 17.
[0031] Specifically, the support frame 1 fixes the upright plate 14, and the upright plate 14 fixes the motor 15. The motor 15 drives the rotating rod 16 to rotate inside the upright plate 14, which in turn drives the cutting blade 18 to rotate. The cutting blade 18 is used to cut the steel coil body 22 into strips. By pulling the locking pin 19, the sliding plate 20 slides inside the fixing block 17. The sliding plate 20 compresses the spring 21. When the locking pin 19 slides out of the rotating rod 16, it drives the fixing block 17 to slide on the outer wall of the rotating rod 16. When it slides to the appropriate position, the spring 21 rebounds and moves the cutting blade 18, thereby flexibly adjusting the distance between the cutting blades 18 to cut steel coils of different widths.
[0032] Reference Figure 6 and Figure 7 A support box 23 is fixedly connected to the upper surface of the support frame 1. A threaded column 24 is rotatably connected inside the support box 23. A handle 27 is fixedly connected to the upper surface of the threaded column 24. A push block 25 is threadedly connected to the outer wall of the threaded column 24. A limit plate 26 is slidably connected to the outer wall of the push block 25. The outer wall of the limit plate 26 is fixedly connected to the inside of the support box 23. A control rod 28 is fixedly connected to the outer wall of the push block 25. The outer wall of the control rod 28 is slidably connected to the inside of the support plate 2.
[0033] Specifically, the support frame 1 fixes the support box 23. By rotating the handle 27, the threaded column 24 rotates inside the support box 23. While the threaded column 24 rotates, the push block 25 slides on the outer wall of the limiting plate 26. The limiting plate 26 limits the push block 25. The push block 25 can drive the control rod 28 to slide inside the support plate 2, thereby adjusting the position of the control rod 28 to better control the unwinding tension.
[0034] Working Principle: When using this cutting device, the starting motor 12 first drives the take-up wheel 13 to rotate, which in turn drives the steel coil body 22, which is mounted on the outer wall of the take-up wheel 13, to be unwound from the unwinding device, thus completing the conveying of the steel coil body 22. During the conveying process of the steel coil body 22, the starting hydraulic cylinder 3 drives the connecting block 4 to slide inside the support platform 5. While the connecting block 4 is sliding, the rack 6 is also driven to slide, which in turn drives the sliding plate 8 to slide on the outer wall of the limiting strip 9. The limiting strip 9 limits the sliding plate 8 and can simultaneously... The gear 7 is driven to rotate, which in turn drives the limiting rod 10 to move. This achieves the effect of centering and clamping the steel coil body 22 with the limiting rod 10, preventing the steel coil body 22 from shifting during the cutting process and affecting the cutting accuracy. After the steel coil body 22 comes out of the unwinding device, it passes the outer wall of the control rod 28, slides on the upper surface of the fixed table 11, and is then wound up on the outer wall of the take-up wheel 13. When it is necessary to adjust the tension during unwinding, the threaded column 24 can be rotated inside the support box 23 by rotating the handle 27. While the threaded column 24 is rotating, it can... The pusher 25 slides on the outer wall of the limiting plate 26, which in turn drives the control rod 28 to slide inside the support plate 2. Adjusting the position of the control rod 28 according to the unwinding speed allows for flexible control of the unwinding tension. When cutting the steel coil body 22 is required, the motor 15 drives the rotating rod 16 to rotate inside the vertical plate 14. Simultaneously, the rotating rod 16 drives the cutting blades 18 to cut the steel coil body 22. When adjusting the spacing of the cutting blades 18, the locking pin 19 can be pulled to drive the sliding plate 20 to slide inside the fixed block 17. The spring 21 is compressed, causing the locking pin 19 to slide out of the rotating rod 16. At this time, the fixing block 17 slides on the outer wall of the rotating rod 16 until it reaches the appropriate position. The spring 21 then rebounds, causing the locking pin 19 to slide inside the rotating rod 16, thereby flexibly adjusting the blade spacing. This device can not only center and clamp the steel coil body 22 to prevent it from shifting during cutting and affecting the cutting accuracy, but also flexibly control the spacing of the cutting blades 18 to cut steel coils of different sizes.
