In some embodiments, the driving structure 20 may be as shown in fig. 2. Referring to fig. 2, the first traction mechanism 30 and the second traction mechanism 50 are set to have a first direction and a second direction perpendicular to the first direction and horizontal to the first direction.

The drive structure 20 includes a worm gear reducer 21 and a driver 22. The worm gear reducer 21 is fixedly arranged on the supporting seat 10, and is provided with a first power output end arranged along a first direction and a second power output end arranged along a second direction. The driver 22 is fixedly arranged on the worm gear reducer 21 and is in power connection with the power input end of the worm gear reducer 21.

It should be noted that, regarding the supporting seat 10 may be a supporting frame structure, which may be hollow below the working platform 11, and the worm gear reducer 21 may be disposed on the bottom surface of the working platform 11, and a plurality of openings may be formed on the working platform 11 correspondingly related to power transmission, as shown in fig. 1 and 2.

In some embodiments, the first traction mechanism 30 and the second traction mechanism 50 may have the structures shown in fig. 1,2 and 4. Referring to fig. 1,2 and 4, the first traction mechanism 30 is identical in structure to the second traction mechanism 50. The first traction mechanism 30 and the second traction mechanism 50 each include a vertical fixed frame 31, a fixed rotating shaft 32, a movable rotating shaft 33, a fixed adapter 301, a movable adapter 34, a lower press roller 35, a lower gear 37, an upper press roller 36, a lower gear 37, and an upper gear 38.

The vertical fixing frame 31 has a through cavity penetrating both sides in the second direction. A fixed adapter 301 and a movable adapter 34 which is positioned above the fixed adapter 301 and can slide vertically are arranged in the through cavity. The fixed rotating shaft 32 is disposed along the second direction and rotatably disposed on the fixed adapter 301, and both ends of the fixed rotating shaft extend out of the fixed adapter 301. One end of the fixed rotating shaft 32 is coaxially connected with a lower pressing roller 35, and the other end is coaxially connected with a lower gear 37. The moving rotating shaft 33 is disposed along the second direction and rotatably disposed on the moving adapter 34, and both ends of the moving rotating shaft extend out of the moving adapter 34. An upper press roller 36 corresponding to the lower press roller 35 is coaxially connected to one end of the moving rotary shaft 33, and an upper gear 38 engaged with the lower gear 37 is coaxially connected to the other end.

The reinforcing steel bar 100 can be transmitted backwards between the upper pressing roller 36 and the lower pressing roller 35, so that the clamping force can be ensured, and the traction transmission effect can be further ensured. The lower gear 37 on the fixed rotating shaft 32 is meshed with the wound gear on the movable rotating shaft 33, so that the upper pressing roller 36 and the lower pressing roller 35 can be guaranteed to rotate simultaneously, the rotation directions are opposite, and the traction effect can be guaranteed.

The first traction mechanism 30 and the second traction mechanism 50 can realize two double traction and increase traction force. And through the meshing of the upper gear 38 and the lower gear 37 in each traction mechanism, the synchronous rotation of the upper press roller 36 and the lower press roller 35 is realized, so that the steel bar 100 between the upper press roller 36 and the lower press roller 35 can be ensured to stably pass through, and the steel bar 100 can be straightened to a certain extent.

It should be noted that, the fixed adaptor 301 may be directly fixed in the through cavity by a bolt connection manner, and the movable adaptor 34 needs to be in a limiting sliding connection with the through cavity in a vertical direction, and a limiting guide rail may be specifically provided, or a guiding chute may be provided on the movable adaptor 34.

It should be further noted that the outer circumferential surface of the lower press roller 35 and the outer circumferential surface of the upper press roller 36 may be provided with annular grooves to facilitate the passage of the reinforcing bars 100. Meanwhile, fixing plates can be arranged at two ends of the vertical fixing frame 31 along the first direction, and through holes for the steel bars 100 to pass through are formed in each fixing plate so as to prevent the steel bars 100 from separating from the lower press roller 35 and the upper press roller 36.

In some embodiments, the vertical fixing frame 31 may have a structure as shown in fig. 1. Referring to fig. 1, the vertical fixing frame 31 is provided with an adjusting structure 39 capable of adjusting the lifting movement of the movable adapter 34.

The vertical position of the movable adapter 34 can be guaranteed to be adjusted by the adjusting structure 39, and then gaps between the lower pressing roller 35 and the upper pressing roller 36 are guaranteed to be adjusted, so that the adaptability of the steel bars 100 with different diameters is guaranteed, the adaptability is improved, meanwhile, the clamping of the steel bars 100 can be guaranteed, and the traction effect is guaranteed.

In this embodiment, the adjusting structure 39 may be an adjusting screw threaded to the top end of the vertical fixing frame 31, the bottom end thereof is rotatably connected to the moving adapter 34, and the top end thereof is provided with a manual wheel.

It should be noted that, the sliding of the movable adapter 34 tends to drive the upper gear 38 to move, so that the upper gear 38 and the lower gear 37 may be disengaged, and thus only fine adjustment without separating from the power connection may be performed, and when the adjustment distance is large, the specification of the upper gear 38 may be changed, thereby further improving the adaptability.

In some embodiments, the first transmission mechanism 70 may be configured as shown in fig. 2. Referring to fig. 2, the first transmission mechanism 70 includes a first pulley 71, a second pulley 72, a guide pulley 73, and a first transmission belt 74. The first pulleys 71 are provided in two, and the two first pulleys 71 are coaxially disposed at one ends of the two fixed rotating shafts 32 away from the lower press roller 35. The second pulley 72 is coaxially disposed on the second power output end of the worm gear reducer 21. The guide pulleys 73 are provided in two, and the two guide pulleys 73 are located between the two first pulleys 71. One end of the first transmission belt 74 is wound around the outer peripheral surfaces of the two first pulleys 71, and the other end passes between the two guide pulleys 73 and is wound around the outer peripheral surface of the second pulley 72.

The first pulley 71 and the second pulley 72 ensure that the fixed shaft 32 is simultaneously rotated, and the second pulley 72 ensures that power is transmitted to the two first pulleys 71 through the first transmission belt 74. The arrangement of the two guide pulleys 73, which involves the height difference between the second pulley 72 and the two first pulleys 71, can ensure that the contact area between the first transmission belt 74 and the second pulley 72 is increased, and simultaneously contacts the first transmission belt 74 to guide the first transmission belt 74, and can avoid larger interference with the working platform 11.

Specifically, the two guide pulleys 73 are rotatably provided on the work table 11 at a position lower than the position of the two first pulleys 71, and the gap between the two guide pulleys 73 is smaller than the diameter of the second pulley 72.

In some embodiments, the alignment mechanism 40 may be configured as shown in fig. 1-3. Referring to fig. 1 to 3, the straightening mechanism 40 includes a lateral adapter 41 and a straightening barrel 42. The two lateral adapter seats 41 are provided, and the two lateral adapter seats 41 are arranged at intervals along the first direction. Each of the lateral adapter seats 41 is provided with an adapter hole whose axis is arranged along the first direction. The size of the transfer hole may be adaptively enlarged to ensure adaptation to different sizes of the reinforcing bars 100.

The straightening barrel 42 is rotatably arranged in the two adapting holes, and two ends of the straightening barrel 42 respectively extend out of the two adapting holes. The straightening barrel 42 has a wire passing hole penetrating along the first direction. A plurality of connecting portions 43 are arranged on the side wall of the straightening barrel 42 at intervals along the first direction, each connecting portion 43 comprises at least two connecting holes which are communicated with the wire transmission holes and are annularly arranged at intervals around the axis of the straightening barrel 42, fixing plugs are detachably connected in the connecting holes, and straightening rotating rollers are connected to the fixing plugs.

The straightening cylinder 42 is driven to rotate by the second transmission mechanism 80, and the straightening rollers in the connecting holes are all abutted against the steel bars 100, so that along with the rotation of the straightening cylinder 42, the straightening rollers rotate around the steel bars 100, and the straightening effect is ensured.

It should be noted that, the fixed plug can be connected with the connecting hole site through screw threads, and the fixed plug can include the cock body, coaxial rotation setting up the bull stick in the cock body, and the bull stick can be fixed on the racing body through the nut. The alignment roller rotates the inner setting at the bull stick, and the axis of rotation sets up perpendicularly with the length direction of bull stick. In addition, the angle of each straightening roller is adjustable, and this technology is the prior art and will not be described here again.

In this embodiment, a wire brush may be installed on the corresponding fixing plug near one of the connection holes in the connection portion 43 of the second traction mechanism 50 to increase the rust removing effect.

In some embodiments, the second transmission mechanism 80 may be configured as shown in fig. 2. Referring to fig. 2, the second transmission mechanism 80 is a belt transmission, one end of which is connected to the first power output end of the worm gear reducer 21, and the other end of which is connected to the other end of the straightening cylinder 42.

The straightening cylinder 42 is arranged in parallel with the axis direction of the first power output end of the worm gear reducer 21, and a belt transmission structure can be adopted.

Another implementation of this embodiment may involve that the end of the straightening barrel 42 is offset from the first power output end of the worm gear reducer 21 in the first direction, so the second transmission mechanism 80 may include a third pulley 81, a fourth pulley 82, a fifth pulley 83, a sixth pulley 84, a second transmission belt 85, and a third transmission belt 86. The third pulley 81 is coaxially disposed on the first power output end of the worm gear reducer 21. The fourth pulley 82 and the fifth pulley 83 are coaxially connected, and the fourth pulley 82 corresponds to the third pulley 81. The sixth pulley 84 is coaxially connected to an end of the straightening barrel 42 and corresponds to the fifth pulley 83. The second transmission belt 85 is sleeved on the outer peripheries of the third belt pulley 81 and the fourth belt pulley 82, and the third transmission belt 86 is sleeved on the outer peripheries of the fifth belt pulley 83 and the sixth belt pulley 84, as can be seen in fig. 2.

In some embodiments, the shearing mechanism 60 may be configured as shown in fig. 1, 3 and 4. Referring to fig. 1, 3 and 4, the shear mechanism 60 includes a support 61, a power shaft 62, a rotating disk 63, and a shear structure 65. The two holders 61 are provided, and the two holders 61 are spaced apart along the second direction. The top end of each support 61 is rotatably provided with a limiting wheel 66, and the axis of each limiting wheel 66 is arranged along the vertical direction. The power shaft 62 is rotatably provided on the two brackets 61 in the second direction. The rotating disc 63 is arranged between the two supports 61 and is rotatably connected with the power rotating shaft 62 through a one-way bearing 64. The outer periphery of the rotating disk 63 is provided with an annular groove 631. The portion of the annular groove 631 at the top end is capable of passing the reinforcing bars 100. The shearing structure 65 is disposed on the rotating disc 63 and corresponds to the annular groove 631 and corresponds to the two limiting wheels 66, and the shearing structure 65 can rotate along with the rotating disc 63 and cut the reinforcing steel bars 100 in the process of passing through the two limiting wheels 66.

The two supports 61 ensure the rotational connection of the power shaft 62, while the power shaft 62 ensures the power connection with the worm gear reducer 21 via the third transmission 90. The rotating disc 63 can drive the shearing structure 65 to rotate, and the two limiting wheels 66 are passed once every rotation, so that the steel bars 100 in the annular groove 631 can be cut when the limiting wheels 66 are passed every time, and fixed-length cutting can be realized.

In addition, the continuous transmission of the reinforcing bars 100 is involved, and the rotation speed of the rotating disc 63 is smaller than the transmission speed of the reinforcing bars 100, so that the reinforcing bars 100 can push the shearing structure 65 forward during the cutting process, and the shearing structure 65 has higher stability and strength, so that the reinforcing bars 100 between the second traction mechanism 50 and the shearing structure 65 can be bent. Therefore, the unidirectional bearing 64 is arranged between the power rotating shaft 62 and the rotating disc 63, so that the shearing structure 65 can feed forward along with the steel bar 100 in the cutting process of the shearing structure 65 on the steel bar 100, and the rotating disc 63 is rotated relative to the power rotating shaft 62, so that the transmission speed of the steel bar 100 is compensated, and the deformation of the steel bar 100 is avoided.

In some embodiments, the shear structure 65 may be configured as shown in FIG. 5. Referring to fig. 5, the shear structure 65 includes a fixed cylinder 651, a slider 652, and a spring 653. The fixed cylinders 651 are provided in two, and the two fixed cylinders 651 are both fixed on the rotary disk 63 and are located on both sides of the annular groove 631 in the second direction, respectively.

The two sliders 652 are provided, and the two sliders 652 are slidably disposed in the two slide chambers 654, respectively.

Each slide 652 is provided with a limit protrusion 656 corresponding to the flange 657. A cutting knife 655 is provided on the end of each slide 652 adjacent the annular recess 631. The springs 653 are two, and the two springs 653 are respectively sleeved on the two sliding blocks 652 and are respectively located in the two sliding cavities 654. One end of each spring 653 abuts against the stopper boss 656, and the other end abuts against the flange 657, so that the corresponding slider 652 can be sprung, and the slider 652 tends to move continuously in a direction away from the annular groove 631.

The two fixed cylinders 651 are respectively connected with the two sliding blocks 652 in a sliding manner, in the process that the fixed cylinders 651 rotate along with the rotating disc 63 for one circle, and pass through the two limiting wheels 66, the inclined surface parts of the sliding blocks 652 are contacted with the corresponding limiting wheels 66, the limiting wheels 66 further push the sliding blocks 652 to the direction of the annular grooves 631, after the two sliding blocks 652 relatively move, the two cutters 655 relatively move, and then extend into the annular grooves 631 to cut the reinforcing steel bars 100,

The structure can effectively reduce the power source, can realize fixed-length cutting, can adapt to the transmission speed of the reinforcing steel bar 100, and has simple structure and strong practicability.

Each of the sliding blocks 652 has a certain length, the sliding block 652 may have a cylindrical shape, or may have a rectangular shape, and when having a rectangular shape, the transmission opening formed by enclosing the flanges 657 is a rectangular opening, and two ends of the sliding block 652 are continuously located in the rectangular opening.

Referring to fig. 2 and 3, the third transmission mechanism 90 is a belt transmission, one end of the third transmission mechanism 90 is connected to the second power output end of the worm gear reducer 21, and the other end is connected to the other end of the power rotating shaft 62.

The belt transmission can effectively transmit the power of the driver 22 to the power rotating shaft 62 at the same time, so that the driving usage can be reduced.

Referring to the different cut lengths, referring to fig. 2 and 3, the third transmission 90 may include a seventh pulley 91, an eighth pulley 92, a ninth pulley 93, a tenth pulley 94, a fourth transmission belt, and a fifth transmission belt 95.

The fourth transmission belt is fitted around the seventh pulley 91 and the eighth pulley 92, and the fifth pulley 83 is fitted around the ninth pulley 93 and the tenth pulley 94.

Since the diameter of the eighth pulley 92 is larger than that of the ninth pulley 93, the third transmission mechanism 90 can achieve deceleration of the second power output end of the turbine speed reducer, thereby extending the time for one rotation of the rotary disk 63. By replacing the eighth pulley 92, cutting of bars 100 of different lengths can be achieved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
