[0053] This utility model embodiment provides a traction straightening mechanism for traction straightening of reinforcing bars. For example... Figures 1-6 As shown, the traction straightening mechanism includes a housing 1 and a first straightening device 2 and a second straightening device 3 disposed on the housing 1.

[0054] The first straightening device 2 includes a first manual clamping assembly 21, a first electric clamping assembly 22, and three first rollers 23 arranged sequentially along the rebar conveying direction. The sliding end of the first manual clamping assembly 21 is provided with a first manual pressure roller 211 located above the two upstream first rollers 23, forming a triangular structure with the first manual pressure roller 211. The first manual clamping assembly 21 can drive the first manual pressure roller 211 to move towards the first rollers 23 to clamp the rebar. The sliding end of the first electric clamping assembly 22 is provided with a first electric pressure roller 221 located above the two downstream first rollers 23, forming a triangular structure with the first electric pressure roller 221. The first electric clamping assembly 22 can drive the first electric pressure roller 221 to move towards the first rollers 23 to clamp the rebar. As a preferred embodiment, the first manual pressure roller 211 is located directly above the two upstream first rollers 23, and the first electric pressure roller 221 is located directly above the two downstream first rollers 23. It is understandable that the first manual pressing component 21 in the first straightening device 2 can be set in two, three or more groups, and the first electric pressing component 22 can also be set in two, three or more groups. Taking the first electric pressing component 22 as having two groups and the first manual pressing component 21 as having one group as an example, there are four first rollers 23. The first manual pressing roller 211 is located above the two upstream first rollers 23, one first electric pressing roller 221 is located above the two middle first rollers 23, and another first electric pressing roller 221 is located above the two downstream first rollers 23.

[0055] The second straightening device 3 includes multiple sets of pneumatic clamping components 31 arranged sequentially along the direction of rebar conveying and second rollers 32 corresponding to each set of pneumatic clamping components 31. Each set of pneumatic clamping components 31 has a pneumatic pressure roller 311 located above the corresponding second roller 32 at its sliding end. The pneumatic clamping components 31 can drive the cylinder 312 to move the pressure roller toward the second roller 32 to clamp the rebar.

[0056] This traction straightening mechanism uses a combination of manual clamping component 21, electric clamping component 22, and pneumatic clamping component 31 to clamp the reinforcing bars, enabling straightening of the reinforcing bars during transport with high consistency. In addition, the use of the electric clamping component 22 allows for memorizing the straightness of the reinforcing bars and one-button straightening, making the straightening operation more convenient. Furthermore, the overall structure is simple and easy to disassemble and maintain.

[0057] Specifically, such as Figure 2 As shown, the first manual clamping assembly 21 includes a manual nut seat 212, a manual screw 213, and a manual slider 214. The manual nut seat 212 is fixedly mounted on the first upper cover 11 of the housing 1; the manual slider 214 is slidably connected to the housing 1, and the first manual pressure roller 211 is connected to the manual slider 214, so that when the manual slider 214 moves up and down reciprocally, it can drive the first manual pressure roller 211 to move closer to or away from the first roller 23, so as to clamp or loosen the steel bar; the manual screw 213 is screwed to the manual nut seat 212. When the manual screw 213 is manually rotated, the manual screw 213 can move toward the manual slider 214 and push the manual slider 214 to drive the first manual pressure roller 211 toward the first roller 23, so as to clamp and straighten the steel bar with the first manual pressure roller 211. In this embodiment, a first thrust ball bearing 216 is provided at the end of the manual screw 213 facing the manual slider 214. By pressing the manual slider 214 with the first thrust ball bearing 216, the rotational friction can be reduced, and wear between the manual screw 213 and the manual slider 214 can be avoided.

[0058] Furthermore, in order to enable the manual slider 214 to reset, the first manual clamping assembly 21 also includes a first compression spring 215 disposed between the end of the manual slider 214 away from the manual screw 213 and the housing 1. When the manual screw 213 is rotated to push the manual slider 214 downward, causing the first manual pressure roller 211 to move toward the first roller 23, the manual slider 214 compresses the first compression spring 215 to store energy; when the manual screw 213 is rotated in the opposite direction, the manual screw 213 moves upward, and the first compression spring 215 releases its elastic potential energy to reset the manual slider 214.

[0059] Specifically, such as Figure 3As shown, the first electric clamping assembly 22 includes a first motor reducer 222, an electric nut seat 223, a first electric screw 224, and an electric slider 225. The electric nut seat 223 is disposed on the first upper cover 11 of the housing 1; the electric slider 225 is slidably connected to the housing 1, and the first electric pressure roller 221 is connected to the electric slider 225, so that when the electric slider 225 moves up and down reciprocally, it can drive the first electric pressure roller 221 to move closer to or away from the first roller 23, so as to clamp or loosen the steel bar; the first electric screw 224 is screwed to the electric nut seat 223 and simultaneously keyed to the output hole of the first motor reducer 222. When the first motor reducer 222 drives the first electric screw 224 to rotate, the first electric screw 224 can move axially along the output hole and push the electric slider 225 to drive the first electric pressure roller 221 to move toward the first roller 23, so as to realize the first electric pressure roller 221 clamping and straightening the steel bar. In this embodiment, a second thrust ball bearing 227 is provided at the end of the first electric screw 224 facing the electric slider 225. By pressing the electric slider 225 with the second thrust ball bearing 227, the rotational friction can be reduced, and wear between the first electric screw 224 and the electric slider 225 can be avoided.

[0060] Furthermore, to enable the electric slider 225 to reset, the first electric clamping assembly 22 also includes a second compression spring 226 disposed between the end of the electric slider 225 away from the first electric screw 224 and the housing 1. When the first motor reducer 222 drives the first electric screw 224 to rotate, causing the first electric screw 224 to push the electric slider 225 downward and move the first electric pressure roller 221 toward the first roller 23, the electric slider 225 compresses the second compression spring 226 to store energy; when the first electric screw 224 is driven to rotate in the opposite direction, the first electric screw 224 moves upward, and the second compression spring 226 releases its elastic potential energy to reset the electric slider 225.

[0061] Specifically, such as Figure 4 As shown, the pneumatic clamping assembly 31 includes a cylinder 312 and a pneumatic slider 313. The cylinder 312 is mounted on the first upper cover 11 of the housing 1; the pneumatic slider 313 is slidably connected to the housing 1, and the pneumatic pressure roller 311 is connected to the pneumatic slider 313 so that the pneumatic slider 313 can simultaneously move the pneumatic pressure roller 311 when it moves up and down; the end of the output rod of the cylinder 312 is connected to the pneumatic slider 313 so that the output rod of the cylinder 312 can simultaneously move the pneumatic slider 313 up and down when it extends or retracts. When the cylinder 312 drives the pneumatic slider 313 to move the pneumatic pressure roller 311 toward the second roller 32, the pneumatic pressure roller 311 can clamp and straighten the reinforcing bar. In this embodiment, the pneumatic clamping assembly 31 is provided with six sets.

[0062] In this embodiment, a floating connector is provided at the output end of the cylinder 312, and a connector connecting seat is installed on the side of the pneumatic slider 313 facing the cylinder 312. The floating connector is connected to the connector connecting seat so that the output rod of the cylinder 312 drives the pneumatic slider 313 to move up and down.

[0063] Optionally, refer to Figure 1 and combined Figures 5-6 As shown, the traction straightening mechanism also includes a third straightening device 4 disposed in the housing 1 and located downstream of the second straightening device 3. The third straightening device 4 includes a second electric pressing assembly 41, a lower pressing assembly 42, and a second manual pressing assembly 43 arranged sequentially along the rebar conveying direction. The sliding end of the second electric pressing assembly 41 is provided with a second electric pressure roller 411, the sliding end of the lower pressing assembly 42 is provided with multiple lower pressure rollers 421 arranged sequentially along the rebar conveying direction, and the sliding end of the second manual pressing assembly 43 is provided with a second manual pressure roller 431. The third straightening device 4 also includes multiple third rollers 44. The second electric pressure roller 411, the lower pressure roller 421, and the second manual pressure roller 431 are located above the third rollers 44 and are staggered from the third rollers 44. The second manual pressing assembly 43, the lower pressing assembly 42, and the second manual pressing assembly 43 can respectively drive the second electric pressure roller 411, the lower pressure roller 421, and the second manual pressure roller 431 to move toward the third rollers 44 to press the rebar. This structure further improves the stability of rebar straightening. In this embodiment, two sets of the second manual clamping assembly 43 are provided.

[0064] Optionally, the pressing assembly 42 includes a pressing drive component and a sliding mounting body 422. The sliding mounting body 422 is slidably connected to the housing 1. The pressing rollers 421 are spaced apart along the rebar conveying direction and connected to the sliding mounting body 422. The pressing drive component can drive the sliding mounting body 422 to move the pressing rollers 421 toward the third roller 44 to clamp the rebar. This structure arranges multiple pressing rollers 421 sequentially and installs them on the sliding mounting body 422, so that when the pressing drive component drives the sliding mounting body 422 to press down, it can drive multiple pressing rollers 421 to clamp the rebar with multiple corresponding third rollers 44 respectively, so that multiple pressing rollers 421 and multiple third rollers 44 form multiple sets of simultaneous pressing structures to improve the stability of rebar straightening.

[0065] In this embodiment, the clamping drive component includes two second motor reducers 423, two second electric screws 425, and two threaded sleeves 424. The two threaded sleeves 424 are fixedly mounted on the housing 1 at intervals along the direction of rebar conveying. The two second motor reducers 423 are mounted on the housing 1. The two second electric screws 425 are screwed to the two threaded sleeves 424 respectively, and the two second electric screws 425 are also keyed to the output holes of the two second motor reducers 423 respectively. When the two second motor reducers 423 drive the two second electric screws 425 to rotate simultaneously, the two second electric screws 425 can push the sliding mounting body 422 downward. In this embodiment, a ring platform is provided in the middle of the second electric screw 425, and a third thrust ball bearing 426 is sleeved on the second electric screw 425. The two ends of the third thrust ball bearing 426 abut against the ring platform and the sliding mounting body 422 respectively.

[0066] Furthermore, to enable the sliding mount 422 to reset, the clamping drive component also includes a third compression spring 427 disposed between the end of the sliding mount 422 facing away from the second electric screw 425 and the housing 1. When the sliding mount 422 moves downward, driving the lower pressure roller 421, the third compression spring 427 is compressed and stores energy; when the second electric screw 425 rotates and moves upward, the third compression spring 427 releases its elastic potential energy to reset the sliding mount 422.

[0067] In this embodiment, the second electric clamping assembly 41 and the first electric clamping assembly 22 have the same structure, which will not be described again here.

[0068] In this embodiment, the second manual clamping component 43 and the first manual clamping component 21 have the same structure. The manual nut seat of the second manual clamping component 43 is set on the second upper cover 12 on the housing 1. The rest of the structure will not be described here.

[0069] Optionally, the first roller 23 is rotatably mounted on the housing 1 via a first gear shaft, and the second roller 32 is rotatably mounted on the housing 1 via a second gear shaft. First steering gear shafts mesh between any adjacent first gear shafts, between any adjacent second gear shafts, and between adjacent first and second gear shafts. A first bearing is provided between each first roller 23 and its corresponding first gear shaft. To achieve the traction of the reinforcing bar, the traction straightening mechanism also includes a first traction mechanism 5. The output end of the first traction mechanism 5 is connected to the first gear shaft with the first bearing. The first traction mechanism 5 provides power for the movement of the reinforcing bar, and by connecting the output end of the first traction mechanism 5 to the first gear shaft with the first bearing, speed mismatches between the first roller 23 connected to the output end of the first traction mechanism 5 and the other first rollers 23 and second rollers 32 are avoided.

[0070] Furthermore, the third roller 44 is rotatably mounted on the housing 1 via a third gear shaft, and a second steering gear shaft meshes between any adjacent third gear shafts. A second bearing is provided between each third roller 44 and its corresponding third gear shaft. To make the movement of the reinforcing bar smoother, the traction straightening mechanism also includes a second traction mechanism 6. The output end of the second traction mechanism 6 is connected to the third gear shaft with the second bearing. The second traction mechanism 6 provides power to the reinforcing bar, and by connecting the output end of the second traction mechanism 6 to the third gear shaft with the second bearing, speed mismatch between the third roller 44 connected to the output end of the second traction mechanism 6 and the other third rollers 44 is avoided.

[0071] It is understood that, except for the first roller 23 and the first gear shaft which are provided with the first bearing, and except for the third roller 44 and the third gear shaft which are provided with the second bearing, the remaining first roller 23 and the first gear shaft, the second roller 32 and the second gear shaft, and the remaining third roller 44 and the third gear shaft are all fixedly connected.

[0072] In this embodiment, the first traction mechanism 5 includes a first traction motor 51, a first large pulley 52, and a first small pulley 53. The first small pulley 53 is disposed on the output shaft of the first traction motor 51. The first large pulley 52 is rotatably connected to the housing 1 and is driven by the first small pulley 53 via a first belt 54. The first large pulley 52 is connected to a first gear shaft equipped with a first bearing. The first traction motor 51 drives the first large pulley 52 to rotate, thereby realizing the rotation of the corresponding first gear shaft, and thus realizing the simultaneous rotation of the remaining first rollers 23 and second rollers 32.

[0073] In this embodiment, the second traction mechanism 6 includes a second traction motor 61, a second large pulley 62, and a second small pulley 63. The second small pulley 63 is disposed on the output shaft of the second traction motor 61. The second large pulley 62 is rotatably connected to the housing 1 and is driven by the second small pulley 63 via a second belt 64. The second large pulley 62 is connected to a third gear shaft equipped with a second bearing. The second traction motor 61 drives the second large pulley 62 to rotate, thereby rotating the corresponding third gear shaft, and consequently, rotating the remaining third rollers 44 simultaneously.

[0074] It is understandable that the outer circumferential surfaces of the first manual pressure roller 211, the first electric pressure roller 221, the pneumatic pressure roller 311, the second manual pressure roller 431, the second electric pressure roller 411, the lower pressure roller 421, the first roller 23, the second roller 32, and the third roller 44 are all provided with grooves for accommodating reinforcing bars.
