Description

Technical Field

[0001] This invention relates to wire tying technology, and more specifically to a wire tying machine for data cable production. Background Technology

[0002] As is well known, data cables are a key component for data transmission between electronic devices. After the data cables are manufactured, they usually need to be wound and tied by a wire tying machine. A wire tying machine is a comprehensive piece of equipment that integrates mechanics, electronics, and automatic control. It mainly consists of several parts, including a frame, a power transmission system, a winding system, a wire tying actuator, and a control system. These parts work together to complete the entire process of automatic feeding, precise winding, rapid tightening, and finished product output of the wires.

[0003] For example, the patent with authorization announcement number CN201751300U, authorization announcement date February 23, 2011, entitled "Power Cord Winding and Tie Machine," includes an operation panel, a winding and tying mechanism, a strapping mechanism, a strap clamping mechanism, a strap feeding mechanism, a cutting mechanism, and a control system. The winding and tying mechanism includes a winding rotating shaft, a winding rotating shaft connecting plate, a winding bar, upper and lower synchronous pulleys, a synchronous belt, a discharge plate, and a servo motor. The winding rotating shaft has a hollow structure, and the strap clamping mechanism is installed in the space of this hollow structure. The strap clamping mechanism is connected to the strap feeding mechanism. This patent achieves a high degree of automation in power cord winding and tying by using the coordinated movement of multiple mechanisms, including a servo motor, a winding and tying mechanism, a strap feeding mechanism, and a strap clamping mechanism. The servo motor drives the winding and tying mechanism to operate, and the strap feeding mechanism cooperates to wind the power cord and tie the strap onto the power cord. Finally, the strap is unloaded by the discharge plate, thus improving production efficiency and reducing production costs.

[0004] For example, patent CN113120345B, authorized on March 13, 2023, entitled "A Wire Winding and Binding Machine," includes a control cabinet, a winding device mounted on the control cabinet, a binding device mounted on the control cabinet, and a main frame positioned between the winding device and the binding device. The winding device includes a winding wheel driven by a winding motor, a wire collecting frame longitudinally positioned outside the winding wheel, an inlet platform positioned between the winding wheel and the wire collecting frame, and an inlet frame positioned above the inlet platform and the wire collecting frame. A core chip on the inlet platform determines whether the end of the wire to be wound can be wound normally based on the actual rotation angle of the winding wheel and the rotation angle range built into the core chip. This design has the advantages of simple overall processing, fast winding and binding speed, and high efficiency.

[0005] The shortcomings of existing technology are that in order to realize the switching of data cable stations and the release of cable ties, two mechanical claws are usually required: one is the mechanical claw for switching stations, and the other is the cable tying mechanical claw. After the cable tie is released, the cable tying mechanical claw clamps and twists the cable tie head, then picks up and moves to release the wrapped data cable. The cable tying mechanical claw has to perform many actions and needs to cooperate with the mechanical claw for switching stations, which makes the overall mechanism of the cable tying machine too complicated. Summary of the Invention

[0006] The purpose of this invention is to provide a wire tying machine for data cable production, so as to overcome the above-mentioned shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wire tying machine for producing data cables includes a workbench, a base slidably mounted on the workbench, a clamping mechanism for clamping a data cable roll rotatably mounted on the base, and a wire tying mechanism also provided on the base.

[0009] During the sliding stroke of the base, the cable tying mechanism presses the cable tie head on the data cable roll, and a drive unit drives the clamping mechanism to rotate to complete the cable tying.

[0010] The aforementioned data cable production cable tying machine has a sliding groove on the worktable, and the base is slidably installed in the sliding groove.

[0011] The aforementioned cable tying machine for data cable production has a rotating shaft rotatably mounted on the base, and a clamping mechanism fixedly connected to the upper end of the rotating shaft.

[0012] The above-mentioned cable tying machine for data cable production includes a clamping mechanism comprising a mounting frame fixed to the upper end of a rotating shaft, two opposing clamping claws rotatably mounted on the mounting frame, the top of the clamping claws having a through-hole opening, and the clamping mechanism further comprising a power component for independently driving the two clamping claws to clamp.

[0013] The above-mentioned cable tying machine for data cable production includes a clamping mechanism that further includes a through-hole in the middle of the clamping claw. Two spring rods are fixed on the mounting frame. The spring rods are correspondingly arranged with the clamping claw and the spring rods pass through the corresponding through-holes. A wire placement part is connected between the tops of the two spring rods. In the initial state, the upper end of the wire placement part and the upper end of the clamping claw are on the same horizontal plane.

[0014] The above-mentioned data cable production cable tying machine includes two limiting brackets fixed on the base. The two limiting brackets are arranged opposite to each other. A sliding member is slidably passed through the limiting bracket. A tying block is formed on the upper end of the sliding member near the clamping mechanism. Two limiting grooves are also opened on the worktable. The lower end of the sliding member is slidably installed in the corresponding limiting groove.

[0015] The aforementioned data cable production cable tying machine includes a limiting groove comprising a first horizontal groove, an inclined groove, and a second horizontal groove, wherein the limiting grooves are connected in sequence as first horizontal groove-inclined groove-second horizontal groove-inclined groove-first horizontal groove.

[0016] In the above-mentioned data cable production tying machine, the sliding component is initially installed in the first horizontal groove.

[0017] The aforementioned cable tying machine for data cable production includes a drive unit comprising a mounting groove on the upper end of a workbench, a rotating shaft slidably mounted in the mounting groove, a drive gear fixedly connected to the lower end of the rotating shaft, a rack fixedly fixed in the mounting groove, the drive gear and the rack meshing with each other, and an electric push rod fixedly connected in the workbench, the movable end of the electric push rod being rotatably connected to the outer wall of the rotating shaft.

[0018] The aforementioned cable tying machine for data cable production has a flexible film connected to the base, and the flexible film covers the limiting groove.

[0019] In the above technical solution, the present invention provides a wire tying machine for data cable production, including a clamping mechanism and a wire tying mechanism. The clamping mechanism is used to clamp the wound data cable and bring the wire ends of the tying close together. The wire tying mechanism is used to press the wire ends of the tying. When the base slides from the tying station to the release station, the wire tying mechanism presses the cable tie head. The driving unit drives the clamping mechanism to rotate in this way to complete the tying. Through the above technical solution, the tying of the data cable is completed by the cooperation of the wire tying mechanism and the clamping mechanism. There is no need to set up a wire tying mechanical claw. Moreover, the tying is completed naturally during the sliding of the base, without the need to cooperate with the mechanical claw of the switching station, which simplifies the overall mechanism of the wire tying machine.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-7As shown in the figure, an embodiment of the present invention provides a cable tying machine for data cable production, including a workbench 1, a base 2 slidably mounted on the workbench 1, a clamping mechanism 3 for clamping a data cable roll rotatably mounted on the base 2, and a cable tying mechanism 4 also provided on the base 2; during the sliding stroke of the base 2, the cable tying mechanism 4 presses the cable tie head on the data cable roll, and a driving unit 31 drives the clamping mechanism 3 to rotate to complete the cable tying.

[0032] Specifically, in this embodiment, a winding mechanism, a cable feeding mechanism, and a cable cutting mechanism are sequentially installed on the workbench 1 according to the process. In addition, a movable mechanical claw is provided on the top of the workbench 1. The winding mechanism is used to wind the data cable, the cable feeding mechanism is used to drive the cable tie to the clamping mechanism 3, and when the cable tie reaches a predetermined length on the clamping mechanism 3, the cable cutting mechanism cuts the cable tie, leaving a cable tie section on the clamping mechanism 3. The mechanical claw is used to pick up the data cable coil and place it on the clamping mechanism 3. The data cable is also located above the cable tie section. The winding mechanism, cable feeding mechanism, cable cutting mechanism, and movable mechanical claw mentioned above are all existing technologies, serving as preparatory work before cable tying, and will not be elaborated upon here. The workbench 1 is square, and the sliding direction of the base 2 is along the length extension direction of the workbench 1. This direction is also the arrangement direction of the winding mechanism, cable feeding mechanism, and cable cutting mechanism. The base 2 is a square block structure. The clamping mechanism 3 is used to clamp the already wound data cable roll fed by the mechanical claw. In addition, the clamping mechanism 3 and the machine... The grippers also coordinate their movements. The initial state of the clamping mechanism 3 is open. After the gripper places the data cable roll on the clamping mechanism 3, it continues to move vertically downwards a certain distance, squeezing the cable tie section and the data cable roll, which also move downwards a certain distance. After the cable tie section and the data cable roll have moved downwards a certain distance, the gripper stops moving. At this time, the clamping mechanism 3 switches to a gripping state. The cable tie ends at both ends of the cable tie section are also pushed to similar positions by the clamping mechanism 3. The cable tying mechanism 4 is used to press the cable tie ends to restrict their movement. When the cable tie head is pushed to a near position, the base 2 begins to slide, thereby driving the tying mechanism 4 to press the cable tie head tightly. At the same time, the clamping mechanism 3 rotates itself, thereby driving the cable tie head to rotate, so that the cable tie heads are wrapped together to complete the tying. Through the above technical solution, the tying mechanism 4 and the clamping mechanism 3 work together to complete the tying of the data cable without the need for mechanical claws. Moreover, the tying is completed naturally during the sliding stroke of the base 2, without the need for additional mechanical claws, reducing the tying action and simplifying the overall mechanism of the tying machine.

[0033] In a complete working process, the sequence includes winding stroke, unwinding stroke, wire cutting stroke, station switching stroke, clamping stroke, cable tie stroke, and reset stroke. During the winding stroke, the winding mechanism winds the data cable. During the unwinding stroke, the cable tie is driven to move onto the clamping mechanism 3. During the wire cutting stroke, the wire cutting mechanism cuts the cable tie so that the cut cable tie segment stays on the top of the clamping mechanism 3. During the station switching stroke, the mechanical claw picks up the data cable coil and places it on the clamping mechanism 3 and the cable tie segment. During the holding stroke, the mechanical claw continues to move downwards a certain distance, squeezing the cable tie section and the data cable roll, which also move downwards a certain distance. Then, the clamping mechanism 3 clamps the data cable roll and brings the cable tie head closer together. During the cable tie stroke, the mechanical claw moves upwards and releases the clamp on the data cable roll. At this time, the base 2 slides, the cable tying mechanism 4 presses the cable tie head, and at the same time, the clamping mechanism 3 rotates to achieve the cable tie. During the reset stroke, the clamping mechanism 3 releases the clamp on the data cable roll, and after the data cable roll falls off, the base 2 resets.

[0034] In another embodiment of the present invention, a slide groove 21 is provided on the workbench 1, and the base 2 is slidably installed in the slide groove 21. The extending direction of the slide groove 21 is the same as the extending direction of the length of the workbench 1.

[0035] In another embodiment of the present invention, a rotating shaft 22 is rotatably mounted on the base 2, and the clamping mechanism 3 is fixedly connected to the upper end of the rotating shaft 22, thus providing the clamping mechanism 3 with the conditions for rotation. When the base 2 slides, the rotating shaft 22 rotates accordingly. That is to say, the movement of the rotating shaft 22 at this time is a combination of sliding and rotation.

[0036] In another embodiment of the present invention, the clamping mechanism 3 includes a mounting frame 32 fixed to the upper end of the rotating shaft 22. The mounting frame 32 is a square frame. Two opposing clamping claws 33 are rotatably mounted on the mounting frame 32. The top of each clamping claw 33 has a through-hole 331. The purpose of the through-hole 331 is to allow the cable tie head to extend from the two through-holes 331 when the tops of the two clamping claws 33 are close to each other, thus avoiding direct contact between the tops of the two clamping claws 33 and the inability to pass the cable tie head. The clamping mechanism 3 also includes a power component that independently drives the two clamping claws 33 to clamp. The main function of the force component is to drive the clamping claws 33 to rotate relative to each other. There are various ways in the existing technology to drive the two clamping claws 33 to move closer or further apart, such as through gear meshing. Therefore, we will not go into details here. During operation, the mechanical claw moves the data cable roll to the top between the clamping claws 33. At this time, the mechanical claw continues to move vertically downward to move the data cable roll between the clamping claws 33. Then, the power component drives the two clamping claws 33 to move closer to each other, so that the upper ends of the clamping claws 33 move closer together to clamp the data cable roll.

[0037] In another embodiment of the present invention, the clamping mechanism 3 further includes a through-hole 34 formed in the middle of the clamping claw 33. Two spring rods 35 are fixed on the mounting frame 32. The through-hole 34 is for the spring rods 35 to pass through, so that the spring rods 35 can be placed in the through-hole 34 of the clamping claw 33. The spring rods 35 and the clamping claw 33 are correspondingly arranged and the spring rods 35 pass through the corresponding through-holes 34. A wire placement part 36 is connected between the tops of the two spring rods 35. The width of the wire placement part 36 is smaller than the width of the through-hole 34. When the clamping claw 33 clamps, both ends of the wire placement part 36 pass through the through-hole 34 to prevent the wire placement part 36 from obstructing the clamping claw 33 after moving downwards. The wire placement part 36 is correspondingly set with the wire feeding mechanism. The cable tie output from the wire feeding mechanism will move directly onto the wire placement part 36. The wire placement part 36 is a block structure with a horizontal upper surface. It is used to place the cable tie. In the initial state, the upper end of the wire placement part 36 and the upper end of the clamping claw 33 are on the same horizontal plane. In actual operation, when the length of the cable tie at the upper end of the wire placement part 36 reaches the predetermined length... When the cable tie section's predetermined length exceeds the length of the cable placement section 36, it is cut by a wire-cutting mechanism, leaving one cable tie section on the cable placement section 36. Then, a mechanical gripper moves the data cable reel above the cable placement section 36. The mechanical gripper then moves vertically downwards, squeezing the cable placement section 36. Simultaneously, the downward movement of the cable placement section 36 squeezes the spring rod 35, causing the data cable reel and cable tie section to move downwards synchronously. After the cable placement section 36, data cable reel, and cable tie section have moved downwards a certain distance, the clamping jaws 33 rotate, bringing their upper ends closer together. At this time, the outlet 331 contacts the cable tie section and pushes the cable tie heads at both ends of the cable tie section closer to each other. Then, the mechanical claw releases its control over the data cable roll and moves upward. Under the elastic action of the spring rod 35, the cable placement part 36 moves upward and pushes the data cable roll and the cable tie section to move upward synchronously. The data cable roll is pressed between the cable placement part 36 and the clamping claw 33. The cable tie head extends to the top of the clamping claw 33. In this way, the data cable roll is clamped, and the movement of the cable tie head to the top of the clamping claw 33 also facilitates the pressing of the adjacent cable tie heads.

[0038] In another embodiment of the present invention, the wire-tying mechanism 4 includes two limiting brackets 41 fixed on the base 2. The two limiting brackets 41 are arranged opposite to each other. Limiting grooves are formed on the limiting brackets 41. Sliding members 42 are slidably passed through the limiting brackets 41. That is, the sliding members 42 are slidably installed in the limiting grooves. The sliding direction of the sliding members 42 is parallel to the width direction of the workbench 1. A wire-tying block 43 is formed on the side of the upper end of the sliding member 42 near the clamping mechanism 3. The wire-tying block 43 is a square block structure. The wire-tying block 43 is preferably a rubber block, which has high hardness and a certain degree of elasticity. Two limiting grooves 44 are also formed on the workbench 1. The lower end of the sliding member 42 is slidably installed in the corresponding limiting groove 44. The limiting groove 44 includes a first horizontal groove 441. The inclined groove 442 and the second horizontal groove 443 are connected in sequence according to the first horizontal groove 441-inclined groove 442-second horizontal groove 443-inclined groove 442-first horizontal groove 441. The purpose of setting the first horizontal groove 441 is to provide a certain sliding space for the sliding member 42 and to prevent it from being directly set in the inclined groove 442. The purpose of setting the inclined groove 442 is to passively drive the sliding member 42 to move closer to each other through the movement of the base 2. The length of the second horizontal groove 443 is greater than that of the first horizontal groove 441. The two inclined grooves 442 are symmetrically arranged with the midpoint of the second horizontal groove 443 as the center. The end of the inclined groove 442 near the second horizontal groove 443 is inclined towards the sliding groove 21. In the initial state, the sliding member 42 is slidably installed in the first horizontal groove 441 near the wire cutting mechanism.

[0039] When the base 2 slides away from the wire-cutting mechanism within the slide groove 21, the limiting bracket 41 and the sliding member 42 slide synchronously away from the wire-cutting mechanism. At this time, the lower end of the sliding member 42 is still sliding within the first horizontal groove 441 near the wire-cutting mechanism. When the lower end of the sliding member 42 slides into the inclined groove 442 near the wire-cutting mechanism, the two sliding members 42 slide towards each other in the width direction of the worktable 1. That is to say, the movement of the sliding member 42 at this time is a combination of sliding in two directions, one of which is sliding along the length direction of the worktable 1. Another direction is sliding along the width of the workbench 1. When the sliding member 42 slides from the inclined groove 442 into the second horizontal groove 443, the sliding member 42 drives the corresponding cable tie block 43 to approach each other and then clamp together. Moreover, the clamping position of the cable tie block 43 is also the position where the cable tie head protrudes. At the same time, the clamping mechanism 3 itself begins to rotate. When the sliding member 42 slides in the second horizontal groove 443, the cable tie block 43 maintains the pressure on the cable tie head, and the clamping mechanism 3 itself continues to rotate. In this way, the two cable tie heads are wrapped together to complete the cable ties of the data cable roll. The inclined groove 442 and the first horizontal groove 441, which are away from the wire cutting mechanism, are for the sliding member 42 to reset, thereby allowing the cable tie block 43 to relax the pressure on the cable tie head, making it easier to remove the data cable roll. This will not be described in detail here.

[0040] In addition, it should be noted that the data cable roll is placed on the cable placement section 36 in a manner perpendicular to the cable placement section 36. The general extension direction of the data cable roll is parallel to the width direction of the workbench 1. In order to avoid the data cable roll obstructing the movement of the sliding member 42, a passage 421 is provided on the upper side of the sliding member 42. The passage 421 is located between the cable tie block 43 and the sliding member 42, so that the data cable roll can pass through the sliding member 42, and also so that the cable tie block 43 does not need to be too long.

[0041] In another embodiment of the present invention, the drive unit 31 includes a mounting groove 311 formed on the upper end of the workbench 1. The two limiting grooves 44 in the above embodiment are symmetrically arranged with the mounting groove 311 as the center, that is, symmetrically arranged on both sides of the sliding path of the base 2. The lower side of the rotating shaft 22 is slidably mounted in the mounting groove 311. A drive gear 312 is fixedly connected to the lower end of the rotating shaft 22. A rack 313 is fixed in the mounting groove 311. The drive gear 312 and the rack 313 mesh with each other. An electric push rod 314 is also fixedly connected inside the workbench 1. The movable end of the electric push rod 314 is rotatably connected to the outer wall of the rotating shaft 22. When the electric push rod 314 pushes the rotating shaft 22 to slide in the mounting groove 311, the base 2 moves accordingly. Since the drive gear 312 meshes with the rack 313, the rotating shaft 22 itself also rotates. The rotation of the rotating shaft 22 drives the clamping mechanism 3 to rotate. The rotating shaft 22 is passively driven to rotate by sliding. In this way, the clamping mechanism 3 rotates while sliding.

[0042] In another embodiment of the present invention, a flexible film 23 is connected to the base 2. The flexible film 23 covers the limiting groove 44. Preferably, the flexible film 23 is transparent. The flexible film 23 is used to prevent the data cable roll from falling into the groove opened at the upper end of the workbench 1. At the same time, when the data cable roll falls onto the flexible film 23, the movement of the flexible film 23 can drive the data cable roll to move further, which is convenient for outputting the data cable roll. A storage box can be set at the other end of the workbench. In this way, the reciprocating movement of the flexible film 23 can automatically transport the data cable roll to the storage box. Moreover, the flexible film 23 also covers and protects the mounting groove 311, the limiting groove 44, and the sliding groove 21.

[0043] Furthermore, after the cable tie head is wound, it is perpendicular to the data cable roll. This is determined by the orientation of the clamping mechanism 3 and the cable tying mechanism 4. In the prior art, even when using a robotic arm for tying, this problem cannot be avoided. When the wound cable tie heads are perpendicular to the data cable roll, it is not convenient for packaging and may also prick the staff or users handling the data cable roll. Therefore, this embodiment provides a further solution, which mainly focuses on improving the limiting groove 44. The shape of the limiting groove 44 in this embodiment is different from that of... The aforementioned limiting groove 44, in this embodiment, still has two limiting grooves 44. The limiting groove 44 in this embodiment also includes a pushing groove 45. The limiting grooves 44 are constructed sequentially as follows: first horizontal groove 441 - inclined groove 442 - second horizontal groove 443 - pushing groove 45. The inclined groove 442 is used for tying the wire, while the pushing groove 45 is used to flatten the tangled cable tie ends. It should be noted that in this embodiment, the first horizontal groove 441 - inclined groove 442 - second horizontal groove 443 are still symmetrically arranged with the mounting groove 311 as the center, i.e., symmetrical. Arranged on both sides of the sliding path of the base 2, the push grooves 45 are arranged in the same direction. One of the push grooves 45 is inclined at the end away from the second horizontal groove 443 towards the mounting groove 311, and the other push groove 45 is inclined at the end away from the second horizontal groove 443 towards the opposite direction from the mounting groove 311. That is to say, the two push grooves 45 are inclined in the same direction, and the inclination, length and inclination direction of the two push grooves 45 are the same. (The subsequent release process of the data cable roll is not the focus of this embodiment and will not be described in detail here.) After the cable tying is completed, the sliding member 42 immediately enters the push groove 45. At this time, since the push groove 45 is inclined in the same direction, the sliding member 42 also presses the cable tie head and moves in the same direction, thereby bending the vertically extending and coiled cable tie head towards the data cable roll. In this way, by designing only one more push groove 45, the bending of the vertically arranged cable tie head can be achieved, so that it is attached to the data cable roll. This makes it easier to pack the data cable roll and also avoids puncturing the staff or users who handle the data cable roll.

[0044] Furthermore, in actual operation, the data cable reel is convex at both ends and concave in the middle. This is because the data cable reel itself has a certain degree of toughness and cannot be completely folded. Moreover, the size of the convexities at both ends of the data cable reel is uncontrollable. During the horizontal movement of the cable tie blocks 43 towards each other, it is highly likely that the convex portions at both ends of the data cable reel will also move inward and be squeezed. Even if the convex portions are not squeezed into the two cable tie blocks 43, it is easy to damage the winding state of the data cable reel. Therefore, this embodiment provides a further... To address the aforementioned technical problems, it should be noted that in this embodiment, the wire-tying block 43 is no longer fixed to the upper end of the sliding member 42. The passage 421 is opened at the upper end of the sliding member 42, and the wire-tying block 43 is rotatably installed in the passage 421 via the connecting shaft 422. A push-out rod 423 is slidably installed on the lower side of the sliding member 42. The push-out rod 423 is L-shaped, and its horizontal section slides through the lower side of the sliding member 42. Both ends of the horizontal section of the push-out rod 423 penetrate the sliding member 42. The horizontal section of the ejector rod 423 extends a certain distance from the end near the clamping mechanism 3, extending outwards from the sliding member 42. A blocking block is formed at the end of the ejector rod 423 near the clamping mechanism 3. This ensures that the ejector rod 423 can only slide a certain distance. The vertical section of the ejector rod 423 extends to the vicinity of the passage 421. A connecting rope 424 is wound around the connecting shaft 422. The movable end of the connecting rope 424 is located below the connecting shaft 422, and the movable end of the connecting rope 424 is connected to the vertical section of the ejector rod 423. A compression spring 425 is connected between the horizontal section of the ejector rod 423 and the inner wall of the limiting slide groove. In the initial state, the height of the cable tie block 43 is relatively high and not aligned with the cable tie head, so as to avoid squeezing the protruding part of the data cable roll when moving horizontally. In addition, the ends of the cable ties 43 that are close to each other are inclined to facilitate the docking of the cable ties 43. A stop part 426 is formed in the opening 421. The stop part 426 is located below the cable tie block 43 and is used to limit the rotation angle of the cable tie block 43.

[0045] When the sliding member 42 slides within the inclined groove 442 (that is, when the cable ties 43 approach each other), there are two strokes of movement between the sliding member 42 and the ejector rod 423: a relative sliding stroke and a synchronous movement stroke. During the relative sliding stroke, the two sliding members 42 slide towards each other. Due to the presence of the compression spring 425, a certain elastic pressure is applied to the ejector rod 423. Therefore, the ejector rod 423 remains stationary, and relative sliding occurs between the sliding member 42 and the ejector rod 423. At this time, the connecting rope 424 is stretched, and the connecting shaft 422 rotates, causing the ends of the cable ties 43 that are close to each other to gradually tilt and rotate downwards. At this time, the cable ties 43 can approach the data cable roll at a height far away from the data cable roll protrusion, avoiding damage to the data cable roll protrusion. To minimize interference, the cable tie block 43 can gradually rotate to approach the recessed portion in the middle of the data cable roll. During the synchronous movement stroke, the sliding member 42 continues to slide within the inclined groove 442. When the sliding member 42 contacts the blocking block, it pushes the blocking block and the ejector rod 423 to move synchronously. At this point, there is no further relative sliding between the sliding member 42 and the ejector rod 423, and the cable tie block 43 contacts the stop portion 426 and cannot rotate downwards. Therefore, the rotation angle of the cable tie block 43 is limited, and the sliding member 42 continues to slide, thereby pressing the cable tie block 43 together in an inclined state. In this way, by tilting the cable tie block 43 downwards first and then moving it horizontally, it is possible to avoid contact between the cable tie block 43 and the protruding portions at both ends of the data cable roll, while ensuring the normal docking of the two cable tie blocks 43.

[0046] In the above embodiment, the port 421 has two functions: first, it is used to pass through the data cable roll, and second, it provides working space for the rotation of the cable tie block 43.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
