[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-8, the present invention provides a technical solution: a high-speed cold-rolled steel bar uncoiling automatic wire feeding device, including a wire feeding device main body 1 and a steel bar coil 22, and a steel bar guiding end 23 is provided on the steel bar coil 22. First feeding frames 15 and second feeding frames 21 are symmetrically arranged on both sides of the wire feeding device main body 1, and a bottom plate 18 is provided at the lower end of the wire feeding device main body 1. Opposite sides of the upper end of the bottom plate 18 are respectively connected with side plates 16, and a top plate 3 is provided between the upper ends of the side plates 16. An arc-shaped second limiting groove 31 is opened at the upper end of the top plate 3, and limiting connection bars 9 are respectively clamped in the second limiting grooves 31, and the length of the limiting connection bar 9 is less than half of the length of the second limiting groove 31. This structure enables the limiting connection bar 9 to move relative to the top plate 3 under the limitation of the second limiting groove 31. A fixing ring 8 is fixed to the upper end of the limiting connection bar 9 by screws, and a connecting rod 7 is connected to the inner side of the fixing ring 8 by screws. A limiting ring 2 is fixed above the top plate 3 by bolts, and the fixing ring 8 and the limiting ring 2 are connected by snap-fitting and movable connection. This structure enables the connecting rod 7, the fixing ring 8, and the limiting connection bar 9 to move synchronously. When the fixing ring 8 moves, it can be limited by the limiting ring 2. A rotating shaft seat 5 is installed at the upper end of the top plate 3, and the rotating shaft seat 5 is connected to the connecting rod 7. This structure enables the rotating shaft seat 5 to be driven by a motor, so that the rotating shaft seat 5 drives the connecting rod 7 to rotate, thereby driving the fixing ring 8 and the limiting connection bar 9 to rotate, and further driving the connecting ring 10 at the lower end of the limiting connection bar 9 to drive the guardrail 11 to rotate, so that the guardrail 11 can rotate above the partition 14. When the coil positioning frame 13 rotates through the rotating shaft 17 and the fixed cylinder 19, it can smoothly pass between the guardrail 11 and the partition 14, and then the steel bar coil 22 on the coil positioning frame 13 reaches between the guardrail 11 and the partition 14. After that, the guardrail 11 rotates above the space between the partitions 14, so that the guardrail 11 can protect the uncoiling and discharging of the steel bar coil 22. A rotating shaft 17 is installed between the side plates 16, and a fixed cylinder 19 is sleeved outside the rotating shaft 17. The fixed cylinder 19 is of a square structure and is located below the partition 14. This structure enables the fixed cylinder 19 to support and position the steel bar coil 22 through the limiting partition 20. The fixed cylinder 19 is located below the partition 14, so that the height of the fixed cylinder 19 is relatively low, which is conducive to the labor-saving feeding of the steel bar coil 22. Two adjacent sides of the fixed cylinder 19 are respectively connected with a coil positioning frame 13, and limiting partitions 20 connected to the fixed cylinder 19 are provided on both sides of the coil positioning frame 13. Opposite sides of the side plates 16 are symmetrically connected with partitions 14 by bolts, and arc-shaped first limiting grooves 26 are opened at the upper ends of the partitions 14. This structure enables the partitions 14 to support the lower end of the guardrail 11. Guardrails 11 are symmetrically arranged between the partitions 14 and the top plate 3, and the lower end of the guardrail 11 is connected with the first limiting groove 26 by snap-fitting and movable connection. This structure enables the first limiting groove 26 to limit the movement of the guardrail 11. A connecting ring 10 is fixed to the upper end of the guardrail 11 by screws,Moreover, the connecting ring 10 is connected to the lower end of the limit connecting bar 9. With this structure, the connecting ring 10 can play a role in connecting and fixing the guardrail 11, enabling the guardrail 11 to be adjusted synchronously. On one side plate 16 of the bottom plate 18, a steel bar lead hole 6 is provided, and a hydraulic cylinder 27 is installed outside the side plate 16 of the bottom plate 18 where the steel bar lead hole 6 is provided. The movable end of the hydraulic cylinder 27 is connected to a movable rod 28. The movable rod 28 is of an L-shaped structure, and the length of the long side of the movable rod 28 is twice the length of the fixed end of the hydraulic cylinder 27. With this structure, the hydraulic cylinder 27 can make the movable rod 28 pass through the steel bar lead hole 6 horizontally, allowing the lead wire clamp 25 to move back and forth relative to the steel bar lead hole 6, realizing the lead wire feeding process of the steel bar lead end 23. Moreover, a lead wire clamp 25 is installed at the end of the movable rod 28. A convex plate is welded outside the side plate 16, and a rotating rod 24 is provided on the convex plate of the side plate 16. And the rotating rod 24 is movably connected to the fixed end of the hydraulic cylinder 27 by insertion. With this structure, the rotating rod 24 can be driven by a motor to make the hydraulic cylinder 27 rotate, so that the movable rod 28 can turn away from the outer part of the material guiding concave wheel 4, facilitating the feeding process of the steel bar. The hydraulic cylinder 27 is an existing hydraulic cylinder structure, which can reciprocate the movable rod 28, enabling the lead wire clamp 25 on the movable rod 28 to extend into one side of the coil positioning frame 13 through the steel bar lead hole 6 between the material guiding concave wheels 4, and allowing the lead wire clamp 25 to clamp the steel bar lead end 23 clamped on the clamping seat 12, realizing the lead wire process of the steel bar lead end 23, so that the lead wire feeding device main body 1 can perform automatic lead wire feeding, facilitating the use of the lead wire feeding device main body 1. Guide material concave wheels 4 are symmetrically installed in the steel bar lead hole 6, and the lead wire clamp 25 is located between the material guiding concave wheels 4. Movable connection seats 30 are provided at the ends of the coil positioning frame 13, and movable connection bars 29 are movably connected to the movable connection seats 30. The other end of the movable connection bar 29 is provided with a clamping seat 12, and the clamping seat 12 is movably connected to the steel bar lead end 23 by clamping.

[0027] Working principle: When using the automatic wire feeding device for high-speed cold-rolled steel bars uncoiling, first place the steel bar coil 22 horizontally on the upper ends of the first loading rack 15 and the second loading rack 21, with the steel bar guiding end 23 on the outer side. Then, push the steel bar coil 22 on the first loading rack 15 onto the coil positioning rack 13. The limiting partition 20 performs limiting and positioning on the steel bar coil 22. Then, make the movable connection bar 29 rotate through the movable connection seat 30, and snap the coil positioning rack 13 onto the clamping seat 12, with the end of the coil positioning rack 13 facing the side plate 16 on the side of the guiding concave wheel 4. After that, the rotating shaft 17 drives the fixed cylinder 19 to rotate under the action of the motor, so that the coil positioning rack 13 reaches between the partitions 14. Then, the rotating shaft seat 5 drives the connecting rod 7 through the motor to drive the fixed ring 8, the limiting connection bar 9, the connecting ring 10, and the guardrail 11 to rotate synchronously, so that the guardrail 11 performs protective treatment on both sides of the coil positioning rack 13. The limiting ring 2 limits the movement of the fixed ring 8. The top plate 3 and the bottom plate 18 are connected and stabilized through the side plate 16. The second limiting groove 31 plays a role in limiting the limiting connection bar 9, and the first limiting groove 26 plays a role in limiting the rotation of the guardrail 11. While the guardrail 11 is rotating, the hydraulic cylinder 27 rotates through the rotating rod 24 under the action of the motor, so that the wire guiding clamp 25 is directly opposite to the guiding concave wheel 4. Then, the hydraulic cylinder 27 drives the wire guiding clamp 25 to rotate through the driving movable rod 28 and passes through the steel bar wire guiding hole 6. The wire guiding clamp 25 clamps the steel bar guiding end 23 on the clamping seat 12. Then, the hydraulic cylinder 27 pulls the steel bar guiding end 23 outward by the wire guiding clamp 25, so that the steel bar guiding end 23 passes through the steel bar wire guiding hole 6. After the steel bar guiding end 23 passes through the steel bar wire guiding hole 6, automatic wire feeding and loading are realized. Then, the hydraulic cylinder 27 rotates the wire guiding clamp 25 to one side through the rotating rod 24. When the wire feeding and loading device main body 1 performs the loading process, the steel bar coil 22 on the second loading rack 21 is fixed to another coil positioning rack 13 in the same way. The wire feeding and loading device main body 1 can alternately perform the loading and replacement process of the steel bar coil 22, thus completing a series of work.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
