[0042] Further, it further comprises,

[0043] The conveying clamp 11 comprises a mounting frame 13 and a pair of clamping parts 14. The mounting frame 13 is arranged on the conveying belt 10. The clamping parts 14 are swingably arranged on the mounting frame 13 by means of torsional springs. The swinging directions of the two clamping parts 14 are opposite. The inner sides of the clamping parts 14 have teeth. The teeth on the two clamping parts 14 are staggered. The teeth have V-shaped grooves 15.

[0044] Further, it further comprises,

[0045] The inlet of the guide ring 12 is an outwardly expanding tapered mouth, and the guide ring 12 is coaxially arranged with the annular support 2.

[0046] Further, it further comprises,

[0047] The conveying mechanism further comprises a pre-straightening mechanism, which comprises a first outwardly expanding track 16 and a second outwardly expanding track 17, the first outwardly expanding track 16 is arranged on the rack 1 along the conveying direction of the conveying belt 10, and the second outwardly expanding track 17 is in multiple sections and is arranged on the rack 1 along the conveying direction of the conveying belt 10, and the first outwardly expanding track 16 and the second outwardly expanding track 17 are respectively located on the upper and lower sides of the conveying belt 10.

[0048] The clamping part 14 is rotationally provided with a roller 18 for cooperating with the first outwardly expanding track 16 and the second outwardly expanding track 17.

[0049] Further, it further comprises,

[0050] The end of the first outwardly expanding track 16 and the second outwardly expanding track 17 has a guide slope 19 for contacting the roller 18.

[0051] In this embodiment, the conveying mechanism is used for conveying steel wires, the guide ring 12 is used for accurately sending the steel wires to the center of the annular support 2, the outwardly expanding tapered mouth at the end of the guide ring 12 plays a guiding role, the conveying mechanism adopts the form of the conveying belt 10, and a plurality of conveying clamps 11 are arranged on the conveying belt 10, the steel wires are clamped and sent through the clamping mode, in order to ensure the stability of the clamping, a row of teeth are arranged on the inward side of the bottom of the clamping part 14, and the teeth have V-shaped grooves 15, the teeth on the two clamping parts 14 are staggered, the two side teeth are engaged after clamping, and the steel wires are positioned at the bottom of the V-shaped groove 15, so as to ensure the stability of the clamping and sending of the steel wires; the V-shaped groove 15 can also adapt to steel wires of various diameters, thereby improving the adaptability of the equipment.

[0052] In order to make the conveying mechanism also have a pre-straightening function, a pre-straightening mechanism is arranged, which comprises a first outwardly expanding track 16 and a second outwardly expanding track 17. A torsion spring is arranged at the hinge point of the clamping part 14, which can provide a force for the inward swinging clamping of the clamping part 14. A roller 18 is further arranged to rotate on the clamping part 14. When the conveying belt 10 is running, the roller 18 can roll on the first outwardly expanding track 16 and the second outwardly expanding track 17. The end of the first outwardly expanding track 16 and the second outwardly expanding track 17 is provided with a guide slope 19, which is located on the moving path of the roller 18. When the conveying belt 10 drives the conveying clamp 11 to move to the guide slope 19, the roller 18 will enter the guide slope 19 and be compressed under the action of the guide slope 19 and be expanded outwardly, entering the first outwardly expanding track 16 and the second outwardly expanding track 17. When the clamping part 14 is on the first outwardly expanding track 16 and the second outwardly expanding track 17, it is in an expanded state and will not clamp the steel wire.

[0053] The first outwardly expanding track 16 and the second outwardly expanding track 17 are respectively located on the upper and lower sides of the conveying belt 10 and are arranged along the conveying path of the conveying belt 10. The second outwardly expanding track 17 is located on one side of the conveying belt 10 conveying the steel wire, and the second outwardly expanding track 17 is in multiple sections and is distributed along the conveying direction of the conveying belt 10. When the clamping part 14 passes through the second outwardly expanding track 17, it will be expanded and will swing inwardly quickly under the action of the torsion spring at the moment of leaving the second outwardly expanding track 17, and will hit the steel wire with the help of the V-shaped groove 15, thereby realizing the pre-straightening function. The conveying belt 10 has both conveying and pre-straightening functions, and the working intensity of the straightening mechanism is reduced by fully utilizing the time of the conveying process. Because there are multiple conveying clamps 11, when several of the conveying clamps 11 pass through the second outwardly expanding track 17, there are still conveying clamps 11 clamping the steel wire, so that the phenomenon of loosening of the steel wire will not occur.

[0054] The first outwardly expanding track 16 is located on the side of the conveying belt 10 that does not convey the steel wire. Because the conveying clamp 11 needs to give way for the steel wire to enter the conveying clamp 11, the conveying clamp 11 needs to be in an expanded state when it is on the side of the first outwardly expanding track 16. Therefore, the guide slope 19 of the first outwardly expanding track 16 is arranged at the end close to the annular support 2. When the conveying clamp 11 moves to the curved section at the end of the conveying belt 10, it will enter the first outwardly expanding track 16, so that the conveying clamp 11 is expanded, thereby allowing the steel wire to continue to be conveyed without being bent. The end of the first outwardly expanding track 16 is arranged at the end of the conveying belt 10 away from the annular support 2, so that the conveying clamp 11 can leave the first outwardly expanding track 16 after entering the straight section from the curved section of the conveying belt 10 and clamp the steel wire, thereby ensuring normal conveying.

[0055] Further, it further comprises,

[0056] The machine frame 1 is further provided with a wire inlet 20, which is located on the front side of the conveying mechanism.

[0057] In this embodiment, the steel wire enters the conveying mechanism through the wire inlet 20, and the wire inlet 20 plays a role of guiding the conveying direction of the steel wire, so that the steel wire can accurately enter the conveying clamp 11.

[0058] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
