Description
Technical Field
[0001] This utility model relates to a wire tying machine, and more particularly to a wire tying machine for power cord production. Background Technology
[0002] Power cords are typically packaged in a coil. To prevent the coil from unraveling, it is usually secured with cable ties (or wire ties). These ties are made by wrapping strips of tape, rope, or wire around the coil to hold it in place. There are two main methods: First, the coil is flattened, and then cable ties are applied at the center, resulting in a figure-eight shape. This method is suitable for shorter power cord coils. Second, multiple cable ties are applied at various points along the round shape of the coil, maintaining its circular shape. This method is suitable for longer power cord coils.
[0003] Currently, most power cord tying machines are suitable for the first tying method, while the second tying method is mostly still done manually or with semi-automated equipment. This makes it difficult to improve the production efficiency of the power cord tying process, resulting in high labor costs. Summary of the Invention
[0004] This utility model provides a wire tying machine for power cord production; it solves the problems of low production efficiency and high labor costs in the existing power cord tying process.
[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a wire tying machine for power cord production, including an operating table, on which a coil constrainer and a stepper motor for driving the coil constrainer to rotate are provided. The coil constrainer has a coil constraining groove coaxial with its rotation axis, the size of which is adapted to the size of the wire roll to be tying. At the same time, the coil constrainer also has a plurality of tying grooves arranged circumferentially. The bottom of the coil constrainer is also provided with a wire feeder, a wire threading tube, a first cylinder slide, and a wire cutter. The wire threading tube is vertically fixed. The wire cutter is located above the threading tube; the operating table is also equipped with a lifting frame, on which a vertically downward connecting rod is fixed, and a first finger cylinder is located at the bottom of the connecting rod, which is directly above the threading tube; the operating table is also equipped with a horizontal moving seat, on which a servo motor is mounted, and a flipping frame is fixed on the shaft of the servo motor, and two mirror-distributed second cylinder slides are mounted on the flipping frame, each of the two second cylinder slides is fixed with a horizontal extension frame, and a second finger cylinder is located at the outer end of the horizontal extension frame.
[0006] The working principle of this utility model is as follows: A power cord is placed into a coil constraint groove. The side walls and bottom of the coil constraint groove constrain the power cord. The wire-tying groove on the coil constraint device ensures that the power cord is fully exposed at that location. By controlling the rotation angle of the stepper motor, each wire-tying groove can rotate to the top of the threading tube. When the wire-tying groove rotates to the top of the threading tube, the lifting frame begins to descend, causing the connecting rod and the first finger cylinder to extend into the wire-tying groove from above until the gripping finger of the first finger cylinder moves to a fixed position above the threading tube. A section of protruding metal wire is reserved inside the threading tube. The metal wire is connected to the wire feeder through the threading tube. After the first finger cylinder clamps the metal wire, the lifting frame begins to rise to a preset height. Then, the horizontal moving seat begins to move towards the wire-tying groove, and the two second finger cylinders on it... The cylinders are arranged vertically and gradually approach the metal cable pulled out by the first finger cylinder until the two second finger cylinders clamp the metal cable. Then the first finger cylinder releases, and the first cylinder slide pushes the wire cutter closer to the metal cable and cuts it. At this time, the two ends of the metal cable are clamped and fixed by the two second finger cylinders. Then the two second cylinder slides push the horizontal extension frame to move towards the center area, while the horizontal moving seat returns to its original position. In this way, the metal cable gradually wraps around the power cord coil in a C-shape. When the two second finger cylinders move to the minimum distance, the servo motor starts to rotate, driving the two ends of the metal cable to rotate, forming a binding structure and tightening the metal cable. Finally, the two second finger cylinders release, the two second cylinder slides return to their original position, and the servo motor also rotates in the opposite direction to return to its original position. Then the stepper motor can continue to drive the coil constraint device, and the cable is tied once for each coil constraint slot according to this process.
[0007] Furthermore, the top of the conduit is equipped with an anti-slip device, which consists of a positioning frame, a fixed block, a movable block, and an elastic element. The positioning frame is fixed to the top of the conduit, and the movable block is horizontally slidably fitted within the positioning frame. Driven by the elastic element, the movable block tends to slide towards the fixed block. The front sidewall of the movable block is inclined. The metal cable passes between the movable block and the fixed block. The movable block on the anti-slip device can apply a certain pressure to the metal cable, and because the front sidewall of the movable block is inclined, the metal cable is not easily allowed to slide downwards, but this does not affect its upward sliding, thus preventing the metal cable from sliding downwards.
[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model can independently perform wire binding operations on power cord coils, which can significantly reduce the number of operators and improve the production efficiency of wire binding, thus helping to reduce the production labor costs of enterprises.

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Example 1: See Figure 1 and Figure 2 A wire tying machine for power cord production includes an operating table 10, on which a coil constrainer 20 and a stepper motor 30 for driving the coil constrainer to rotate are provided. The coil constrainer has a coil constraining groove 21 coaxial with its rotation axis. The size of the coil constraining groove is adapted to the size of the wire roll 1 to be tying. Simultaneously, the coil constrainer also has three tying grooves 22 arranged circumferentially (see...). Figure 5 The coil restraint device is also equipped with a wire feeder 40, a wire conduit 50, a first cylinder slide 60, and a wire cutter 70 at its bottom. The wire conduit is vertically fixed, and the wire cutter is located above the wire conduit. A guide wheel 41 is also rotatably fitted below the wire conduit. The metal binding wire 2 on the wire feeder enters the wire conduit through the guide wheel. The operating table is also equipped with a lifting frame 80, on which a vertically downward connecting rod 81 is fixed. A first finger cylinder 90 is located at the bottom of the connecting rod and is located directly above the wire conduit. The operating table is also equipped with a horizontal moving seat 100, on which a servo motor 110 is mounted. A flipping frame 120 is fixed on the shaft of the servo motor. Two mirror-distributed second cylinder slides 130 are mounted on the flipping frame. A horizontal extension frame 140 is fixed on each of the two second cylinder slides. A second finger cylinder 150 is mounted on the outer end of the horizontal extension frame.
[0017] The working principle of this embodiment is as follows: The power cord is placed into the coil constraint groove. The two side walls and the bottom of the coil constraint groove can constrain the power cord. The wire-tying groove on the coil constraint device makes the power cord in that part completely exposed. By controlling the rotation angle of the stepper motor, each wire-tying groove can rotate to the top of the wire-passing tube. When the wire-tying groove rotates to the top of the wire-passing tube, the lifting frame begins to descend, so that the connecting rod and the first finger cylinder extend into the wire-tying groove from above, until the gripping finger of the first finger cylinder moves to the fixed position above the wire-passing tube. A section of protruding metal wire is reserved in the wire-passing tube. The metal wire passes through the wire-passing tube and is connected to the power supply. After the device is connected, the first finger cylinder clamps the metal cable, and the lifting frame rises to the preset height. Then, the horizontal moving seat moves towards the cable groove, with the two second finger cylinders positioned vertically on it, gradually approaching the metal cable pulled out by the first finger cylinder until the two second finger cylinders clamp the metal cable. Then, the first finger cylinder releases, and the first cylinder slide pushes the wire cutter towards the metal cable and cuts it. At this point, both ends of the metal cable are held and fixed by the two second finger cylinders. Then, the two second cylinder slides push the horizontal extension frame towards the center area, while the horizontal moving seat returns to its original position. In this way, the metal cable gradually wraps around the power cord coil in a C-shape (see...). Figure 4 When the two second finger cylinders move to the minimum distance, the servo motor starts to rotate, driving the two ends of the metal binding wire to rotate, forming a binding structure and tightening the metal binding wire. Finally, the two second finger cylinders are released, the two second cylinder slides are reset, and the servo motor also rotates in the opposite direction to reset. Then the stepper motor can continue to drive the coil constraint device, and the binding wire is tied once for each coil constraint slot according to this process.
[0018] See Figure 3 The top of the conduit is equipped with an anti-slip device 160, which consists of a positioning frame 161, a fixed block 162, a movable block 163, and an elastic element 164. The positioning frame is fixed to the top of the conduit, and the movable block is horizontally slidably assembled within the positioning frame. Driven by the elastic element, the movable block tends to slide towards the fixed block. The front sidewall of the movable block is inclined. The metal cable passes between the movable block and the fixed block. The movable block on the anti-slip device can apply a certain pressure to the metal cable, and because the front sidewall of the movable block is inclined, the metal cable is not easy to slide downwards, but it does not affect its upward sliding, thus preventing the metal cable from sliding downwards.
[0019] In this embodiment, the flipping frame needs to perform a flipping action, and the second cylinder slide and the second finger cylinder on it need to be connected to the air source through a hose. In order to avoid the hose from becoming excessively tangled due to the flipping frame flipping, the maximum number of rotations of the servo motor is ≤2 revolutions.
[0020] See Figure 1In this embodiment, the wire cutter is a pneumatic scissor. A linear slide 170 is vertically fixed on the operating table, and a lifting frame is fixedly connected to the slide of the linear slide. A multi-axis cylinder 180 is also horizontally provided on the operating table, and a horizontal moving seat is fixed to the extension end of the multi-axis cylinder.

All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
