DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See Figure 1-7 The steel bundle 23 is formed by bundling long steel materials using steel wire. The intertwined binding joint 30 has an upwardly curved spiral binding section 31 (where two steel wire ends are intertwined), and a forked steel wire 32 at the end of the spiral binding section 31. This binding joint 30 needs to be processed.

[0029] A steel bundle joint processing device is used to process the binding joints of steel bundles, wherein the binding joints have an upward-curved spiral binding section, and include a conveyor 1 for conveying steel bundles, wherein the conveyor 1 includes a frame 35, a plurality of conveying rollers 33 arranged on the frame 35, and a motor 34 for driving the conveying rollers 33 to rotate to convey the steel bundles 23. First, the steel bundles are conveyed on the conveyor, and a guide device 2 for guiding the passing path of the spiral binding section is provided on the frame of the conveyor 1. A wire winding device 3 is provided on the rear side of the guide device 2. The wire winding device 3 is located on the upper side of the conveyor 1. The wire winding device 3 is used to spirally wind the binding joint guided by the guide device 2 and enter the wire winding device 3. The rear side of the wire winding device 3 is provided with a pressing device 4. The pressing device 4 is located above the conveyor 1. The pressing device 4 is used to press the binding joint downward so that the binding joint will not curl up.

[0030] Furthermore, the wire winding device 3 includes a winding shaft 5 arranged on the upper side of the conveyor 1 and a first limiting structure and a second limiting structure 14 docked with the guide device 2. The first limiting structure is arranged on the winding shaft 5 to limit the lower side of the spiral binding segment. The second limiting structure 14 is located on the upper side of the first limiting structure to constrain the upper side of the spiral binding segment. The second limiting structure 14 can rotate around the winding shaft 5. After the spiral binding segment leaves the guide device 2, it enters the first limiting structure and the second limiting structure 14. The second limiting structure 14 can rotate to drive the binding joint to spirally wrap around the winding shaft 5. In order to facilitate the implementation of more specific winding operations, a support frame 6 is provided on the frame of the conveyor 1, and a mounting platform 7 that can move up and down is provided on the support frame 6, and a first reciprocating drive device 8 is provided between the support frame 6 and the mounting platform 7 to control the movement of the mounting platform 7. The winding shaft 5 is fixed on the mounting platform 7, and the inner side of the winding shaft 5 has a penetrating hollow structure, and the lower end of the winding shaft 5 has a hinge seat 9. The first limiting structure includes a U-shaped fork 10 with a closed end hinged to the hinge seat 9, and the open end of the U-shaped fork 10 faces the guide device 2, and the rear side of the closed end of the U-shaped fork 10 is provided with a hinge ear 11. A second reciprocating drive device 12 is fixedly provided in the direction of the upper end of the winding shaft 5, and the movable end of the second reciprocating drive device 12 is hinged with a connecting rod 13, and the other end of the connecting rod 13 passes through the hollow structure of the winding shaft 5 and is hinged to the hinge ear 11. Furthermore, the second limiting structure 14 includes a turntable 15 rotatably mounted on the winding shaft 5, a shaft cylinder 16 is fixedly provided on the turntable 15 and extends upward, a first gear 17 is fixedly provided on the upper end of the shaft cylinder 16, a driving motor 18 is provided in the upper end direction of the winding shaft 5, a second gear 19 is provided on the output shaft of the driving motor 18 and is engaged with the first gear 17 for transmission, the turntable 15 has a groove 20 opening toward the guide device 2, and a pull groove 21 with a width greater than the opening width of the groove 20 is provided on the bottom side of the groove 20.

[0031] The specific operation is as follows: through the guidance of the guide device, the lashing joint 30 is simultaneously positioned in the slot 20 and the fork of the U-shaped fork 10. Then, the drive motor 18 controls the slot 20 to rotate with the turntable 15. The rotation of the upper slot 20 causes the lashing joint 30 to spirally wrap around the winding shaft and be wound up. The U-shaped fork 10 restrains the lower end of the lashing joint from slipping during the winding process. However, after winding, the second reciprocating drive device 12 pulls the connecting rod 13 to control the U-shaped fork 10 to flip the car vertically. During this process, the first reciprocating drive device 8 controls the mounting platform 7 to move upward to remove the winding shaft from the lashing joint. After the lashing joint enters the slot, the lashing joint will tilt and embed in the pull slot during the movement of the turntable, achieving better guidance of the lashing joint during the rotation of the turntable 15 and preventing the lashing joint from falling out of the slot. To ensure precise control of the turntable, such as conveniently controlling the starting position of the slot and adjusting the number of rotations, the drive motor 18 is a servo-controlled motor.

[0032] The first reciprocating drive device 8 and the second reciprocating drive device 12 are selected as hydraulic telescopic cylinders.

[0033] The guide device 2 also includes guide bars 22 in a figure-eight configuration. The guide bars 22 have parallel straight segments at their proximal ends and an outward curvature at their distal ends. The guide bars 22 are fixedly connected to the frame of the conveyor 1 via a connecting bracket. The outward curvature at the distal ends of the guide bars 22 guides the lashing joints, while the parallel straight segments at their proximal ends position the lashing joints. A proximity detection switch 29 is located on the guide device 2 side of the winding shaft 5. The detection switch 29 determines whether the lashing joint has entered the slot.

[0034] Furthermore, to better flatten the binding joint, the pressing device 4 includes a first mounting bracket 24 and a second mounting bracket 25 fixedly mounted on the frame of the conveyor 1. A pressure plate 26 is provided between the first mounting bracket 24 and the second mounting bracket 25. One side of the pressure plate 26 is movably connected to the first mounting bracket 24. A third reciprocating drive device 27 is provided on the first mounting bracket 24 to control the up and down movement of the connected side of the pressure plate 26. A fourth reciprocating drive device 28 is controlled on the second mounting bracket 25 to control the up and down movement of the other side of the pressure plate 26. A detection device for detecting the passage of the binding joint is provided in front of the pressure plate 26. The detection device can be used to determine the action instructions of the pressing device 4. At the same time, the action of the pressing device 4 can also be controlled by adjusting the distance between the pressing device 4 and the wire winding device.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
