[0039] Reference Figures 1-6 An automatic wire wrapping and binding device, comprising:

[0040] The strapping mechanism 1 includes a strapping frame 1-5. The strapping frame 1-5 has an opening on one side for the cable to pass through. The strapping frame 1-5 is equipped with a dragging air shear assembly 1-1, a twisting air shear assembly 1-2, a shearing air shear assembly 1-3, and a blocking telescopic assembly 1-4.

[0041] The winding mechanism 2 includes a winding frame 2-3, a central rotating shaft 2-5 is mounted through the winding frame 2-3 and fixedly connected to the winding frame 2-3, and a notched gear 2-6 is rotatably connected to the outer wall of the end of the central rotating shaft 2-5 near the binding mechanism 1, and a notch is opened on one side of the central rotating shaft 2-5, the axis direction of the central rotating shaft 2-5 and the notched gear 2-6 coincides with the axis direction of the opening, so that the cable is located in the central rotating shaft 2-5, the notched gear 2-6 and the opening; the winding frame 2-3 is provided with a drive assembly for driving the notched gear 2-6 to rotate, and the notched gear 2-6 is provided with a wire feeding disc assembly 2-8 and a wire feeding assembly 2-9;

[0042] The walking mechanism 3 is mounted on the walking frame. The binding frame 1-5 is located at one end of the walking frame. The wire winding mechanism 2 slides relative to the walking frame through the walking mechanism, so that the wire winding mechanism 2 can move closer to or further away from the binding mechanism 1.

[0043] This equipment can be hoisted and transported, or it can be fixed in place. Align the notched gear 2-6 and the opening of the binding frame 1-5 with the horizontally placed cable, and then push it in horizontally so that the axis of the central rotating shaft 2-5 coincides with the axis of the cable. Begin a series of actions such as winding and binding the cable. After binding is completed here, the equipment can be hoisted to the next binding position, or the equipment can be fixed in place and the cable can be dragged to the next binding position to continue the binding operation.

[0044] Further optimization of the design includes the following components for the telescopic barrier:

[0045] Fixed sleeve 1-4-4, fixed sleeve 1-4-4 is fixedly connected to the side of strapping machine frame 1-5;

[0046] Hollow sleeve 1-4-2 is located inside fixed sleeve 1-4-4, and the outer wall of hollow sleeve 1-4-2 slides in contact with the inner wall of fixed sleeve 1-4-4. One end of hollow sleeve 1-4-2 passes through the strapping machine frame 1-5 and has a groove. A compression spring 1-4-5 is provided between the other end of hollow sleeve 1-4-2 and the inner cavity of fixed sleeve 1-4-4. A blocking component is provided inside hollow sleeve 1-4-2.

[0047] The design has been further optimized, and the blocking components include:

[0048] Small pull rod 1-4-3 passes through hollow sleeve 1-4-2 and slides in contact with the inner wall of hollow sleeve 1-4-2. One end of small pull rod 1-4-3 is fixedly connected to the output end of cylinder 1-4-6.

[0049] Two levers 1-4-1 are hinged in the middle of the groove. The other end of the two levers 1-4-1 has a strip hole. The other end of the small pull rod 1-4-3 is fixed with a crossbar. The crossbar passes through the strip hole of the two levers 1-4-1 and slides in contact with the inner wall of the strip hole, so that the two levers 1-4-1 can open or close.

[0050] Further optimization of the scheme, the wire feeding disc assembly 2-8 includes:

[0051] Fixed shaft 2-8-1 passes through notched gear 2-6 and is fixedly connected to notched gear 2-6;

[0052] Rotating sleeve 2-8-4 is sleeved on fixed shaft 2-8-1, and the inner wall of rotating sleeve 2-8-4 is in sliding contact with fixed shaft 2-8-1. Friction elements are provided on both sides of rotating sleeve 2-8-4.

[0053] The coiled sleeve is fitted onto the rotating sleeve 2-8-4 and is engaged with the rotating sleeve 2-8-4. A large nut 2-8-5 is threadedly connected to the rotating sleeve 2-8-4, and the large nut 2-8-5 abuts against the coiled sleeve.

[0054] Further optimization of the design, the friction components include:

[0055] The large friction plate 2-8-2 is positioned between the rotating sleeve 2-8-4 and the fixed shaft 2-8-1;

[0056] Small friction plate 2-8-6, disc spring assembly 2-8-7 and pressure plate 2-8-8 are sleeved on fixed shaft 2-8-1, pressure plate 2-8-8 abuts against disc spring assembly 2-8-7, small friction plate 2-8-6 is arranged between disc spring assembly 2-8-7 and rotating sleeve 2-8-4, small nut 2-8-9 is threadedly connected to fixed shaft 2-8-1, small nut 2-8-9 abuts against pressure plate 2-8-8.

[0057] The notched gear 2-6 is fixed to the winding frame 2-3 via the central rotating shaft 2-5 and the roller assembly 2-4. A feeding disc assembly 2-8 and a feeding assembly 2-9 are mounted on the notched gear 2-6. A servo motor drives two small gears 2-7 via a synchronous belt mechanism 2-1, causing the notched gear 2-6 to rotate. A tensioning mechanism 2-2 ensures accurate installation of the synchronous belt. The feeding disc assembly is fixed to the notched gear 2-6 via a fixed shaft 2-8-1. A rotating sleeve 2-8-4 is fitted onto the fixed shaft 2-8-1. Large friction plates 2-8-2 and small friction plates 2-8-6 are mounted at both ends of the rotating sleeve 2-8-4. Outside the small friction plate 2-8-6 are, in sequence, a disc spring assembly 2-8-7, a pressure plate 2-8-8, and a small nut 2-8-9. The friction force on the rotating sleeve 2-8-4 is adjusted by changing the engagement of the disc spring assembly 2-8-7 and by tightening the small nut 2-8-9. The wire spool 2-8-3 is fitted onto the rotating sleeve 2-8-4, and the evenly distributed round holes on the inner rim of the wire spool 2-8-3 are embedded into the corresponding cylindrical pins on the rotating sleeve 2-8-4. When winding the wire, the wire spool 2-8-3 and the rotating sleeve 2-8-4 rotate synchronously. The outer side of the wire spool 2-8-3 is restricted from axial movement by the large nut 2-8-5 tightened on the rotating sleeve 2-8-4 to prevent the wire spool 2-8-3 from falling off during the winding process.

[0058] Further optimizations to the plan include:

[0059] Several rollers are rotatably connected to the winding machine frame 2-3, and the rollers slide in contact with the outer ring of the notched gear 2-6. The rollers form a roller group 2-4.

[0060] Further optimization of the solution, the driving components include:

[0061] Synchronous belt mechanism 2-1 is mounted on winding machine frame 2-3 and is driven by servo.

[0062] Several pinions 2-7 are connected to the synchronous belt mechanism 2-1 for transmission, and the pinions 2-7 mesh with the notched gear 2-6.

[0063] Further optimizations to the plan include:

[0064] Several tensioning mechanisms 2-2 slide in contact with the synchronous belt on the synchronous belt mechanism 2-1.

[0065] In this invention, a synchronous belt drives the notched gear set 2-6 to rotate, ensuring synchronized rotation of the two small gears 2-7. The central shaft 2-5 and roller set 2-4 simultaneously constrain the rotation of the notched gear 2-6, increasing the stability of the equipment. A combination of disc springs presses against the friction plates. By changing the engagement method of the disc spring set 2-8-7 or tightening the locking nut at the end of the screw mechanism, the magnitude of the frictional resistance generated by the wire rope reel during rotation and wire release is adjusted, ensuring consistent winding tension. The blocking telescopic mechanism, which ensures that the two ends of the wire cross at the same position, adopts a sleeve-type structure with a built-in compression spring. When the cylinder 1-4-6 retracts, the oscillating retraction of the paddle 1-4-1 and the axial retraction of the telescopic rod are performed in steps.

[0066] The working process of this invention is as follows:

[0067] Before winding the wire, the wire is pulled out from the wire spool 2-8-3 and passes through the wire feeding assembly 2-9 from the end of the wire nozzle. The dragging air shear assembly 1-1 extends downward along the linear guide under the action of the cylinder, clamps the end of the wire, and then returns to its original position. To determine the winding distance, the wire spool 2-8-3 assembly and the wire feeding assembly 2-9 rotate around the cable under the drive of the notched gear 2-6. During the first winding, the wire is positioned in the groove formed by the lower surface of the lever 1-4-1 and the front conical surface of the hollow sleeve 1-4-2. After the wire has wound a full circle on the cable, the traveling mechanism 3, under the control of the servo motor, drives the winding mechanism 2 at a relatively high speed to wind the required distance via the screw and nut mechanism. The wire winds n times on the cable with a large pitch. The distance between the end face of the wire feeding nozzle and the three air shears on the same plane is the winding length. Begin tightly winding the wire, ensuring that the speed of the winding mechanism 2 driven by the traveling mechanism 3 matches the speed at which the wire is wound onto the cable, thus ensuring a tight arrangement of the wire loops. When the wire ejector reaches the coplanar position of the three air shears, the last loop is wound, ensuring that it passes through the groove formed by the upper surface of the lever 1-4-1 and the front conical surface of the hollow sleeve 1-4-2. At this point, the two ends of the wire form an intersection point on one side of this groove (the side away from the cable), and the rotating winding and horizontal traveling actions stop. The shearing air shear assembly 1-3, driven by a cylinder, moves upward along a linear guide rail, cutting the wire from the front end of the wire-ejecting nozzle. At this time, the wire near the wire-ejecting nozzle is clamped by the shearing air shear, while the cut side is not clamped and remains in this position. The rotating air shear assembly 1-2, driven by a cylinder, extends horizontally forward along the linear guide rail, clamping the intersection point of the wire. Then, the cylinder 1-4-6 in the blocking telescopic assembly 1-4 drives the small pull rod 1-4-3 to retract axially, causing the two levers 1-4-1 to swing. Their vertical edges retract into the opening of the front conical surface of the hollow sleeve 1-4-2, and smoothly transition with the front conical surface of the hollow sleeve 1-4-2. The cylinder 1-4-6 continues to retract, and the hollow sleeve 1- 4-2 compresses the spring 1-4-5, keeping the front end of the hollow sleeve 1-4-2 away from the twisting air shear (to avoid interference during rotation); the dragging air shear assembly 1-1 loosens the wire. At this time, the twisting air shear rotates under the transmission of the gear mechanism, tightening the wire onto the cable. Then, the twisting air shear assembly 1-2 loosens the wire and returns horizontally to its initial position under the drive of the cylinder; the dragging air shear assembly 1-1 extends downward under the drive of the cylinder, clamps the wire end at the front end of the wire ejector nozzle, and the shearing air shear assembly 1-3 releases this end and returns to its initial position. The dragging air shear assembly 1-1 clamps the wire end and returns to its initial position, thus completing one wire wrapping and binding action.

[0068] This invention consists of three parts: a binding mechanism 1, a wire winding mechanism 2, and a traveling mechanism 3. The wire rope is fixed to the notched gears 2-6, and the rotation of the gears winds the cable located at the center of the gears. Simultaneously, the traveling mechanism 3 (screw and nut mechanism) drives the wire winding mechanism 2 to move axially along the cable, ensuring a tight arrangement between each winding turn. The binding mechanism 1, composed of three pneumatic shears, completes the combined actions of wire dragging, cutting positioning, and twisting binding.
