DETAILED DESCRIPTION

[0028] In order to further understand the characteristics, technical means and specific purposes and functions reached by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0029] Referring to Figures 1-9 The utility model discloses an automatic feeding steel bar straightening machine, including the rack 1, the top of rack 1 is fixed with the straightening mechanism 2 of steel bar straightening, the one side of the top of rack 1 is close to the straightening mechanism 2 and is provided with the base 3, is provided with two groups of conveying mechanism 4 that can synchronous adjustment spacing on the base 3, and conveying mechanism 4 includes two groups of moving seat 41 that can be close to each other or be away from each other, and the top of moving seat 41 is provided with two groups of conveying roller 43 that can rotate along the central axis, and a plurality of bosses 44 that can be adapted with the rib of steel bar surface are equidistantly arranged on conveying roller 43.

[0030] When two groups of moving seat 41 are close to each other, moving seat 41 drives two groups of conveying roller 43 to move to the both sides of steel bar respectively, until the boss 44 arranged on conveying roller 43 and the rib structure on steel bar realize adaptation. In the process of conveying roller 43 rotation, conveying roller 43 drives steel bar to move at uniform speed in clockwise and counterclockwise directions through boss 44 respectively, to realize automatic feeding.

[0031] Referring to Figure 4 The bottom of moving seat 41 is fixed with the fourth motor 42 for driving conveying roller 43 to rotate, and conveying roller 43 is fixed to the output end of fourth motor 42.

[0032] To realize the rotation of the conveying roller 43, the conveying roller 43 is fixed at the output end of the fourth motor 42 and is powered by the fourth motor 42.

[0033] Referring to Figure 2 and Figure 3 , the base 3 is provided with a plurality of accommodation grooves 31 for guiding the sliding of the moving seat 41 in a specific direction.

[0034] To ensure the stability of the moving seat 41 during movement, the moving seat 41 can move inside the accommodation groove 31, effectively avoiding the deviation of the moving seat 41.

[0035] Referring to Figure 2 , Figure 3 and Figure 4 , the conveying mechanism 4 further comprises two groups of adjusting frames 45 for driving the moving seat 41 to move inside the accommodation groove 31, and the moving seat 41 is movably arranged on the adjusting frame 45; the bottom of the base 3 is provided with a first lead screw 34 for driving the two groups of adjusting frames 45 to move closer to or away from each other, and the adjusting frame 45 is arranged on the first lead screw 34; the bottom of the base 3 is further provided with a second motor 35 for driving the first lead screw 34 to rotate, and one end of the first lead screw 34 is fixedly connected with the output end of the second motor 35.

[0036] When conveying a steel bar with a larger diameter, the second motor 35 drives the first lead screw 34 to rotate, so that the two groups of adjusting frames 45 move closer to each other, and in turn drive the two groups of moving seats 41 to move inside the accommodation groove 31 and move away from each other. Conversely, when conveying a steel bar with a smaller diameter, the second motor 35 drives the first lead screw 34 to rotate in the opposite direction, so that the two groups of adjusting frames 45 move away from each other, and in turn drive the two groups of moving seats 41 to move closer to each other. The conveying mechanism 4 can be adjusted according to actual processing requirements.

[0037] Referring to Figure 2 , Figure 3 and Figure 4 , the bottom of the base 3 is symmetrically provided with two slide rails 32 on both sides for guiding the horizontal movement of the adjusting frame 45, and the adjusting frame 45 is provided with a second sliding groove 46 for sliding cooperation with each slide rail 32.

[0038] When the adjusting frame 45 moves, the adjusting frame 45 slides along the slide rail 32 through the second sliding groove 46, avoiding deviation of the adjusting frame 45 when moving, and ensuring that the adjusting frame 45 can move stably.

[0039] Referring to Figure 2 and Figure 3As shown, the top of the base 3 is symmetrically provided with two sets of limiting mechanisms 5 for preventing the steel bars from deviating during feeding. The bottom of the base 3 is provided with a second lead screw 37 for driving the two sets of limiting mechanisms 5 to move closer to or farther away from each other. One side of the base 3 is provided with a third motor 38 for driving the second lead screw 37 to rotate. One end of the second lead screw 37 is fixedly connected to the output end of the third motor 38. The base 3 is symmetrically provided with a plurality of first sliding grooves 36 for guiding the limiting mechanisms 5 to move in a specific direction.

[0040] When it is necessary to adjust the distance between the two sets of limiting mechanisms 5 to adapt to steel bars of different diameters, the third motor 38 is first started. The output end of the third motor 38 rotates, driving the second lead screw 37 to rotate. Since the second lead screw 37 is connected to the limiting mechanisms 5 through some form of connection such as the cooperation of a nut and a lead screw, when the second lead screw 37 rotates, the second lead screw 37 drives the limiting mechanisms 5 to move along the first sliding grooves 36. The presence of the first sliding grooves 36 ensures that the limiting mechanisms 5 can only move in a specific direction, thereby maintaining the stability of the movement of the limiting mechanisms 5. By adjusting the distance between the two sets of limiting mechanisms 5, it can be ensured that the steel bars will not deviate during the feeding process, thereby affecting the straightening effect.

[0041] Referring to Figure 5 As shown, the limiting mechanism 5 includes a sliding frame 51 mounted on the second lead screw 37. The top of the sliding frame 51 is symmetrically provided with two vertical mounting shafts 52. The outer part of the mounting shaft 52 is provided with a limiting roller 53 that can rotate along the central axis of the mounting shaft 52.

[0042] When the two sets of sliding frames 51 move closer to each other, the sliding frames 51 drive the limiting rollers 53 to move closer to the two sides of the steel bars through the mounting shafts 52, ensuring that the steel bars do not deviate during movement.

[0043] Referring to Figure 2 and Figure 3 As shown, the base 3 is also provided with a guide pipe 6 for guiding the steel bars to enter.

[0044] During the feeding process of the steel bars, the guide pipe 6 can guide the steel bars to enter the conveying mechanism 4, avoiding the deviation of the steel bars from the correct feeding path.

[0045] Referring to Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the straightening mechanism 2 comprises a mounting frame 21 fixed on the top of the frame 1, and a plurality of driving straightening wheels 22 are arranged on one side of the mounting frame 21 in the horizontal direction at equal intervals, and a belt pulley 221 connected by a belt is arranged on the other side of the driving straightening wheel 22, and the belt pulley 221 is fixed on the driving straightening wheel 22; a first motor 24 is fixed on the top of the frame 1 close to the straightening mechanism 2, and the output end of the first motor 24 is fixedly connected with one of the driving straightening wheels 22.

[0046] When the first motor 24 is started, the output end of the first motor 24 starts to rotate. Since the output end of the first motor 24 is fixedly connected with one of the driving straightening wheels 22, the driving straightening wheel 22 connected with the first motor 24 will rotate with the output end of the first motor 24. Since the belt pulley 221 is fixed on the driving straightening wheel 22 and connected by a belt, when the driving straightening wheel 22 connected with the first motor 24 rotates, it will drive the other driving straightening wheels 22 connected by the belt to rotate synchronously. In this way, all the driving straightening wheels 22 will rotate at the same speed and direction, thereby straightening the reinforcing bars passing through.

[0047] As shown in Figure 6 , Figure 7 , Figure 8 and Figure 9 , the inside of the mounting frame 21 is provided with a lifting frame 231 capable of moving longitudinally, and a driven straightening wheel 235 capable of cooperating with the driving straightening wheel 22 to straighten the reinforcing bars is arranged on the lifting frame 231, and a vertical threaded rod 233 is arranged at the center of the top of the lifting frame 231, and two slide rods 234 for preventing the lifting frame 231 from deviating when moving are symmetrically arranged on both sides of the threaded rod 233; a mounting seat 211 for mounting the threaded rod 233 is arranged at the center of the top of the mounting frame 21, and a rotating wheel 212 capable of rotating is arranged on the top of the mounting seat 211, and the rotating wheel 212 is threadedly connected with the threaded rod 233, and slide holes 213 for guiding the slide rods 234 to move in the vertical direction are symmetrically arranged on the top of the mounting frame 21.

[0048] In order to straighten the reinforcing bars, the lifting frame 231 drives the driven straightening wheel 235 to move downward. By rotating the rotating wheel 212 on the mounting seat 211, the threaded rod 233 can be driven to move longitudinally, so that the lifting frame 231 drives the driven straightening wheel 235 to approach the driving straightening wheel 22. In this process, the slide rods 234 arranged on the top of the lifting frame 231 slide in the slide holes 213, ensuring that the lifting frame 231 does not deviate when moving longitudinally. So that the driving straightening wheel 22 and the driven straightening wheel 235 can cooperate to straighten the reinforcing bars.

[0049] The utility model discloses a reinforcing steel bar conveying mechanism, which comprises a conveying mechanism 4, a first motor 24, a driving straightening wheel 22, a lifting frame 231, a driven straightening wheel 235, a second motor 35, a first screw rod 34, two groups of adjusting frames 45, two groups of moving seats 41, two groups of conveying rollers 43, a third motor 38, a second screw rod 37, a sliding frame 51, a fourth motor 42, a guide pipe 6 and a third motor 38.

[0050] The above embodiments only express one or several embodiments of the utility model, and the description is more specific and detailed, but it can not be understood as the limitation of the scope of the utility model. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
