[0015] Support frame 104 horizontal free end is provided with camera 112, by camera, steel wire knot of reinforcing steel bar binding can be quickly and accurately identified, if not in appropriate position, slightly move manually, it is beneficial to the stable clamping and rotation of pneumatic finger and loosening spiral knot steel wire.

[0016] In order to avoid lifting bundled reinforcing steel into inclined hopper, walking frame 108 is connected to the slider of horizontal linear travel module 107 by electric rotating table 122, walking frame is rotated by electric rotating table, and then the structure of pneumatic finger is rotated to the back side, so that the space above the slope hopper is left, which facilitates the discharge of hoisted and bundled reinforcing steel, and is safer.

[0017] The clamping surface of the clamping end of pneumatic finger 110 is provided with anti-skid lines, which can improve the clamping stability and reliability, in order to be more beneficial to accurate clamping.

[0018] The horizontal beam of the walking frame 108 is provided with an upper horizontal linear module moving forward and backward on one side. The lifting cylinder 109 is connected to the slider of the upper horizontal linear module through the flange plate 124, so that the pneumatic fingers can move forward and backward, which is more conducive to the transverse and longitudinal movement of the pneumatic fingers and the vertical rapid positioning, improves the positioning accuracy, and greatly improves the unbundling efficiency of at least two bundled steel wires.

[0019] The unbundling mechanism of the steel bar feeding mechanism is used in cooperation with the steel bar feeding mechanism. The feeding mechanism 1 comprises an unbundling mechanism 101, a single-bar splitting mechanism 102 and a single-bar conveying mechanism 103. The unbundling mechanism 101 is installed on the top of the support frame 104. The top of the support frame 104 is provided with a slope hopper 105. The single-bar splitting mechanism 102 is installed at the transverse strip-shaped discharge port 106 of the slope hopper 105. The single-bar conveying mechanism 103 is installed at the bottom of the slope surface of the support frame 104, and is used to send the steel bars 4 sent out by the single-bar splitting mechanism 102 into the feeding port of the steel bar bending machine 2. The transverse strip-shaped discharge port 106 is connected to the single-bar conveying mechanism 103 through the sliding slope surface 121. The sliding slope surface 121 is fixedly connected to the support frame 104, and the lower end is slightly higher than the walking sliding wheel 117 of the single-bar conveying mechanism 103. The unbundling mechanism is used to unbundling and loosen the hoisted bundled multiple steel bars and place them in the slope hopper. The single-bar splitting mechanism is used to split and feed the steel bars in the slope hopper into the single-bar conveying mechanism. The feeding mechanism greatly reduces the labor intensity (when bending the steel bars with a diameter of more than 20 mm and a length of more than 4 m, the conventional operation requires manual unbundling of the bundled steel bars, and two people are needed to lift and feed the steel bars into the feeding roller, and then push the steel bars into the steel bar bending machine for bending). The feeding mechanism saves time and labor, and does not need manual unbundling and feeding. The operation safety is higher.

[0020] The single-bar splitting mechanism 102 comprises double rollers 113. The double rollers 113 are located at the transverse strip-shaped discharge port 106. The double rollers 113 are fixedly connected to the driving shaft 114 on the left and right sides respectively. The driving shaft 114 is rotatably connected to the bearing seat 115 at both ends. The bearing seat 115 is fixedly connected to the support frame 104 and extends out at one end to be connected to the power driving mechanism. The double rollers 113 are provided with a U-shaped notch 116 at the corresponding position. The notch 116 can accommodate a steel bar 4. When the notch 116 is located at the lower side, the extracted steel bar 4 can automatically fall off. The single steel bar in the slope hopper falls into the notch. Under the clockwise driving action of the driving shaft, the steel bar first reaches the discharge port. Under the action of the weight of the steel bar, the steel bar can automatically fall off from the discharge port and onto the sliding slope surface. This structure is simple in splitting and arrangement, and can output single steel bars according to the needs. The automatic feeding is simple. For large-diameter and long steel bars (diameter of more than 20 mm and length of more than 4 m), the time-consuming and labor-intensive manual lifting and feeding of two people is avoided, and the safety is higher.

[0021] The roller faces of the double rollers 113 are provided with a plurality of convex points staggered to improve the friction of rolling and facilitate the entry of the straightened steel bars into the gap and improve the accuracy of clamping into the gap.

[0022] The power driving mechanism adopts a variable speed motor 125 fixedly connected to the support frame 104, and the front side wall of the inclined hopper 105 opposite to the double rollers 113 is provided with an arc-shaped cavity 126 coaxial with the double rollers 113 to provide a rotating cavity for the rotation of the double rollers 113 and facilitate the rotation of the double rollers.

[0023] In order to realize the single-directional feeding of the single steel bar to the feeding port of the bending device, the single-directional feeding mechanism 103 comprises a plurality of walking sliding wheels 117, the wheel groove of each walking sliding wheel 117 is V-shaped to accommodate the single steel bar, each walking sliding wheel 117 is rotatably connected to the bottom of the inclined surface of the support frame 104, and a double-groove belt pulley 118 is connected to the side of each walking sliding wheel 117 extending out of the rotating position, two adjacent double-groove belt pulleys 118 are connected by a belt 119, and the double-groove belt pulleys 118 are connected to the driving belt pulley of a feeding driving motor 120 by the belt, the feeding driving motor 120 is installed on the support frame 104 and driven by the feeding driving motor to drive all the groove wheels to rotate and feed stably and reliably.

[0024] The use method is as follows: the feeding mechanism unbundles the bundled steel bars and feeds the single steel bars to the feeding port of the steel bar bending machine, and the single steel bars are moved to the set position under the action of the guide wheel set and the feeding roller of the steel bar bending machine, the end of the single steel bars is supported on the auxiliary support walking platform during the movement, the steel bar bending machine performs the bending operation, the auxiliary support walking platform follows the walking auxiliary support, the bent steel bar is removed after the bending operation is completed, the auxiliary support walking platform is moved to the starting position, and the bending of the next steel bar is continued.
