[0039] In this specific embodiment, the automatic feeding component includes a bolt storage box 1 and a guide plate 2. The bolt storage box 1 has a bolt cavity for storing bolts. A through groove is provided in the portion of the bolt cavity above the clamping component. One end of the guide plate 2 is rotatably connected to the top of the through groove via a pin, and a limit hook is provided on the lower surface of the other end of the guide plate 2.

The pin connection between the guide plate 2 and the bolt storage box 1 adopts a clearance fit, which facilitates the rotation of the guide plate 2 around the pin. When the guide plate 2 rotates to a certain angle and the gap between the upper and lower clamping plates 3 is equal to the outer diameter of the left and right bolts, the bolts automatically enter between the clamping rollers and the belt 11 to complete the loading. The bolt storage box 1 is precision machined to produce the inner cavity and outer surface of the bolts, as well as the connecting pin holes and bolt holes. The bolt holes at the bottom of the bolt storage box 1 are connected to the clamping drive switch and the integrated frame 14.

[0040] The clamping component includes a clamping plate 3, a rotating traction shaft 4, a connecting rod 5, and a clamping roller 6. One end of the clamping plate 3 is fixedly connected to the end of the rotating traction shaft 4. An eccentric connecting part is provided in the middle of the rotating traction shaft 4, and the axis of the eccentric connecting part is not coaxial with the axis of the rotating traction shaft 4. The eccentric connecting part is rotatably connected to one end of the connecting rod 5, and the other end of the connecting rod 5 is connected to the gripping component.

[0041] The rebar conveying component includes a conveyor plate 7, a helical gear 8, and a helical rack 9. One end of the helical rack 9 is connected to the clamping drive switch 15 of the gripping component, and one end of the conveyor plate 7 is connected to the gripping retainer 16 of the gripping component. The helical gear 8 is disposed at one end of the conveyor plate 7 and meshes with the helical rack 9. In a more specific embodiment, the other end of the conveyor plate 7 is provided with an arc-shaped notch, and a unidirectional feed structure is provided on the side wall of the arc-shaped notch. The conveyor plate 7 is machined to its designed shape. The clamping surface of the conveyor plate 7 is made by simultaneously machining concentric circles in the upper and lower parts, and a triangular unidirectional feed structure is machined on the contact surface.

The helical gear 8 is connected to the conveyor plate 7 through a pin, driving the conveyor plate 7 to clamp the rebar and complete the clamping and feeding of the rebar.

[0042] The power unit includes a belt roller 10, a belt 11, a driven gear shaft 12, and a driving gear shaft 13. The belt roller 10 is connected to the gripping component, the driving gear shaft 13 is driven by the driven gear shaft 12, and the belt 11 is positioned between the belt roller 10 and the driven gear shaft 12 to drive the bolt to rotate. The driving gear shaft 13 is driven by a drive motor, and the bolt is automatically tightened by switching the drive motor on and off.

[0043] The gripping components include an integrated frame 14, a clamping drive switch 15, and a gripping retainer 16. The gripping retainer 16 has a through hole along the feeding direction of the extra-long rebar, and one side of the gripping retainer 16 is open. The clamping drive switch 15 is slidably disposed inside the gripping retainer 16, and the integrated frame 14 is disposed on one side of the gripping retainer 16. The power component is disposed on the integrated frame 14. The clamping component and the rebar conveying component are both disposed between the integrated frame 14 and the clamping drive switch 15. In a more specific embodiment, the integrated frame 14 is a one-piece structure. A C-shaped opening is provided on the side of the integrated frame 14 away from the gripping retainer 16. Multiple mounting holes of different diameters are provided around the C-shaped opening of the integrated frame 14. The drive gear shaft 13 is installed in the first mounting hole in the middle of the integrated frame 14. A second mounting hole is provided, slightly above and below, on the side of the first mounting hole away from the gripping retainer 16, where the driven gear shaft 12 is installed. The distance between the first and second mounting holes is such that the gears on the driven gear shaft 12 and the drive gear shaft 13 can mesh. A third mounting hole is provided at the top and bottom of the C-shaped opening of the integrated frame 14, for installing the rotating traction shaft 4. A fourth mounting hole is provided between the third and second mounting holes, for installing the belt roller 10. A mounting seat is provided at an angle to the horizontal direction on the side of the integrated frame 14 near the gripping retainer 16, for installing the conveyor plate 7 and the helical gear 8. More specifically, each mounting base includes two coaxially arranged mounting rings. One end of the transmission plate 7 is provided with two connecting rings. The distance between the inner sides of the two connecting rings is greater than or equal to the distance between the outer sides of the two mounting rings. The distance between the inner sides of the two mounting rings is greater than the thickness of the helical gear 8. The helical gear 8 and the connecting rings are connected on the same connecting shaft by interference fit or key connection. The connecting shaft and the mounting rings are clearance fit. Thus, when the helical rack 9 moves, it can drive the helical gear 8 to drive the transmission plate to rotate around the connecting shaft. A clearance groove is provided at the middle position of the top and bottom of the integrated frame 14, so that one end of the connecting rod 5 is connected to the clamping drive switch 15, and the other end is connected to the rotating traction shaft 4 and can pass through the clearance groove, so that the connecting rod 5 does not interfere with the integrated frame 14. In a further specific embodiment, the clamping drive switch 15 has a U-shaped structure. The opening end of the clamping drive switch 15 has a side mounting hole for connecting with the helical rack 9 on both sides at the top and bottom, and a middle mounting hole for connecting with the connecting rod 5 is provided at the middle of the top and bottom.In a further embodiment, the gripping retainer 16 has an isosceles triangle cross-section. A mounting plate extends outward from the top and bottom of the base of the isosceles triangle. The mounting plate has through bolt holes for connecting to the integrated frame 14 and the bolt storage box 1. A through hole is provided along the waist of the isosceles triangle and penetrates the base of the isosceles triangle. Thus, the clamping drive switch 15 can enter the through hole through the base of the isosceles triangle and slide within the gripping retainer 16.

[0044] By gripping the clamping drive switch 15 and the gripping retainer 16, the clamping drive switch 15 slides within the gripping retainer 16. The clamping drive switch 15 drives the rotating traction shaft 4 to rotate via the connecting rod 5, thereby causing the clamping plate 3 to rotate. The clamping drive switch 15 drives the helical rack 9 to rotate the helical gear 8, thereby causing the transmission plate 7 to rotate at a certain angle.
