Description

Technical Field

[0001] This invention belongs to the field of cable processing technology, and specifically relates to a cable processing and threading device. Background Technology

[0002] A cable is an insulated wire bundle used to transmit electrical energy or signals, typically composed of multiple strands of metal wires twisted together. Cable manufacturing and processing wiring devices are auxiliary mechanisms used in the production process to guide, transport, and position the metal filaments or cable cores. They enable the multiple strands to converge along a predetermined path before twisting and maintain stable tension in each unit during cabling, preventing scratches and tangling, and ensuring structural precision.

[0003] Chinese patent CN118571572B discloses a DC high-voltage cable conductor stranding tension control device, including a base, a wire reel, a rotating seat, and a turntable rotatably mounted on the base. The wire reel has a wire unwinding coil, and both the rotating seat and the turntable have multiple circumferentially arranged wire-passing holes. The rotating seat has multiple circumferentially arranged mounting grooves, and an upper clamping member is slidably mounted radially along the rotating seat within the mounting grooves. Lower clamping members are fixedly mounted on the rotating seat at positions corresponding to the upper clamping members. The beneficial effects of this invention are: when the tension of the wire changes, the elastic force of the elastic element changes, causing the top rod to slide along the bearing plate. The sliding of the top rod drives the drive rod to rotate through the transmission assembly, thereby adjusting the clamping force of the upper and lower clamping members on the passing wire. By increasing or decreasing the friction between the upper and lower clamping members and the wire, the tension of the wire is adjusted.

[0004] However, the above technical solution still has the following problems. This solution adjusts cable tension through friction clamping, but when the cable tension changes, the adjustment effect of friction is relatively slow, and it is difficult to make quick and accurate adjustments according to different operating conditions, resulting in tension instability during high-speed operation or process changes. This single tension adjustment method not only affects the quality and stability of the cable, but may also have an adverse impact on the service life and maintenance of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a cable processing and threading device, which aims to solve the problems of lagging tension adjustment, poor adaptability, and difficulty in quickly responding to changes in working conditions during the threading and twisting of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable processing and threading device, comprising: a support base and a threading frame rotatably mounted on the support base, and further comprising: A conductor assembly is mounted on a wire guide frame. The conductor assembly includes a conductor reel mounted on the wire guide frame. The conductor reel has a conductor groove, and a position adjustment mechanism is provided in the conductor groove. The position adjustment mechanism can adjust the position of the conductor core in the conductor groove. A conductor wheel is rotatably mounted on the position adjustment mechanism, and a lead-in groove that mates with the conductor core is provided on the conductor wheel. A support adjustment assembly is provided on the conductor assembly. The support adjustment assembly includes a support block rotatably mounted on the conductor disk, an adjustment block slidably mounted on one end of the support block, and a pressure roller rotatably mounted on the adjustment block. The pressure roller cooperates with the conductor roller. A limit protection component is installed on the lead wire assembly. The limit protection component includes a limit block that is slidably installed in the lead wire groove, and a spring piece is provided on the limit block.

[0007] Its effect is that, through the cooperation of the conductor wheel and the pressure wheel, the tension of the wire core can be dynamically adjusted in real time, with a rapid response, effectively avoiding problems such as wire breakage or uneven twisting caused by tension fluctuations, and improving the quality of cable processing.

[0008] A further technical solution of the present invention is that the support base is provided with a driving device capable of controlling the rotation of the threading frame on a fixed axis, the threading frame is provided with multiple sets of threading holes evenly distributed, the threading frame is provided with a lead wire cavity inside, and the lead wire cavity passes through the axial direction of the threading frame.

[0009] A further technical solution of the present invention is that the conductor reel is disposed on the side where the wire core passes through the wire hole, and two sets of fixing discs are disposed on the wire threading frame. The fixing discs are respectively disposed on both sides of the conductor reel. Positioning wheels that cooperate with the wire hole are rotatably disposed on the fixing discs. Multiple sets of positioning wheels are disposed and are evenly distributed along the fixing discs. Multiple sets of conductor grooves are evenly distributed and correspond to the positioning wheels. The conductor grooves are opened radially along the conductor reel and penetrate the end face of the conductor reel away from the wire threading frame.

[0010] A further technical solution of the present invention is that the position adjustment mechanism includes a positioning block slidably disposed inside the wire groove, a spiral shaft rotatably disposed on the side of the positioning block near the wire threading frame, the other end of the spiral shaft being threadedly connected to the wire disc, a placement block slidably disposed inside the wire groove, the placement block being disposed on the side of the positioning block away from the spiral shaft, a first elastic element being disposed on the positioning block, the other end of the first elastic element being connected to the placement block, and a wire wheel rotatably disposed on the side of the placement block away from the positioning block, the wire wheel always being further away from the wire threading frame than the positioning wheel.

[0011] Its effect is that the position of the positioning block is adjusted by the spiral shaft, and the initial position of the guide wheel is set in conjunction with the first elastic element. The operation is simple and can quickly adapt to the initial tension requirements of different wire diameters.

[0012] A further technical solution of the present invention is that one end of the adjusting block is connected to a second elastic element, the other end of the second elastic element is connected to a support block, the pressure roller is located on the side of the adjusting block away from the second elastic element, the pressure roller is located on the side of the wire wheel away from the wire threading hole, and the pressure roller is always located on the side of the wire wheel away from the wire threading frame during twisting.

[0013] A further technical solution of the present invention is that a third elastic element is provided at the pivot of the support block, the other end of the third elastic element is connected to the wire reel, the width of the end of the adjusting block inserted into the wire groove is less than the width of the wire groove, the end of the wire groove away from the wire threading frame is provided with a constriction, the width of the constriction is less than the width of the wire groove, and the width of the constriction is greater than the width of the wire core, the width of the end of the adjusting block inserted into the wire groove is greater than the width of the constriction, so that the adjusting block can be limited by the constriction.

[0014] Its advantages are: the support block can be rotated open to the side, and the wire core can be quickly inserted in conjunction with the shrinking opening without threading; the third elastic element ensures that the support block automatically resets and seals the shrinking opening, making operation convenient and saving downtime.

[0015] A further technical solution of the present invention is that the first elastic element is configured as a spring, the second elastic element is configured as a spring, and the third elastic element is configured as a torsion spring.

[0016] A further technical solution of the present invention is that multiple sets of limiting blocks are evenly arranged, the limiting blocks can slide back and forth to approach or move away from the shaft of the guide wheel, the spring is arranged on the side of the limiting block near the shaft of the guide wheel, the other end of the spring is connected to the inside of the lead groove, and the elastic force of the spring is less than the force exerted on the limiting block when the wire core is normally twisted.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the linkage structure of the pressure roller and the conductor roller, adjusts the tension of the metal wire in real time, solving the problems of lagging tension adjustment and poor adaptability in the prior art. When the tension of the wire core fluctuates, the conductor roller can slide radially in real time, dynamically compensating for the path length of the wire core between the positioning rollers; at the same time, the radial movement of the conductor roller and the pressure change of the pressure roller form a two-way adjustment, making the tension adjustment more precise, enabling rapid response to changes in working conditions, and improving the stability and quality of cable stranding.

[0018] 2. This invention achieves rapid threading and breakage protection through the structural cooperation of the limiting protection component and the support adjustment component. The support block can be rotated laterally, and the constricted design allows the wire core to be directly inserted into the wire slot from the side without threading, significantly reducing downtime. In the event of a breakage, the limiting block automatically pops out under the action of the spring and clamps the broken wire end, effectively preventing the wire core from tangling or flying off. This avoids the wire core tangling or damage caused by tension fluctuations in traditional equipment, thereby improving the safety and working efficiency of the threading device.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-9The present invention provides the following technical solution: a cable processing and threading device, including a support base 1, a threading frame 2, a conductor assembly 3, a support adjustment assembly 4, and a limit protection assembly 5.

[0023] A support base 1 is placed horizontally on the ground, and a cable threading frame 2 is rotatably mounted on the support base 1. It guides multiple cable cores through a specific path for insertion and exit. One end of the cable threading frame 2 evenly introduces the cable cores, while the other end leads them out, converging at the center point for twisting. A conductor assembly 3 is mounted on the cable threading frame 2. The conductor assembly 3 ensures the cable cores accurately pass through the designated path during threading by adjustment and guidance, providing appropriate traction and tension control to ensure stability during the threading process. A support adjustment assembly 4 is mounted on the conductor assembly 3. This assembly supports the cores on the conductor assembly 3 and adjusts the tension on the cores to maintain them within a set range, preventing excessive or insufficient tension from affecting the quality of cable twisting. A limit protection assembly 5 is mounted on the conductor assembly 3. This assembly protects the cores on the conductor assembly 3, preventing them from getting stuck or tangled due to excessive looseness or sudden wire breakage during movement within the conductor assembly 3, thus avoiding damage to the threading equipment.

[0024] like Figures 1-3 As shown, the cable threader 2 passes through the support base 1 and can rotate along its internal fixed axis. A drive device (not shown) is provided on the support base 1, which controls the rotation of the cable threader 2 along its fixed axis. Multiple sets of threading holes 21 are evenly distributed on the cable threader 2, allowing the wire core to pass through one end of the cable threader 2 through the threading hole 21 and exit from the other end. A lead-in cavity 22 is provided inside the cable threader 2, extending axially along the cable threader 2. The main wire core used for producing cables passes through the lead-in cavity 22.

[0025] During cable processing, the main conductor is first passed through the lead cavity 22, and then multiple sets of conductors are sequentially passed through multiple sets of threading holes 21. The conductors passing through the threading holes 21 are evenly distributed around the main conductor. At this time, the drive device can be activated, which controls the threading frame 2 to drive the conductors to rotate synchronously, so that the conductors are evenly twisted on the main conductor.

[0026] like Figures 2-7As shown, the conductor assembly 3 includes a conductor reel 31 mounted on the threading frame 2. The conductor reel 31 is positioned on the side where the conductor core exits through the threading hole 21. Two sets of fixing discs 32 are mounted on the threading frame 2, respectively positioned on both sides of the conductor reel 31. Positioning wheels 321, which cooperate with the threading hole 21, are rotatably mounted on the fixing discs 32. Multiple sets of positioning wheels 321 are evenly distributed along the fixing discs 32. The conductor core exiting through the threading hole 21 first moves to the fixing disc 32 on the side of the conductor reel 31 closest to the threading hole 21 and overlaps with the positioning wheel 321 corresponding to the threading hole 21. The conductor reel 31 has conductor grooves 311, which are evenly distributed in multiple sets and correspond to the positioning wheels 321. The conductor grooves 311 are radially distributed along the conductor reel 31 and penetrate the end face of the conductor reel 31 away from the threading frame 2. A position adjustment mechanism is provided within the conductor grooves 311, which allows adjustment of the position of the conductor core as it passes through the conductor reel 31.

[0027] The position adjustment mechanism includes a positioning block 33 slidably disposed inside the wire guide groove 311. A spiral shaft 331 is rotatably disposed on the side of the positioning block 33 near the wire guide 2. The other end of the spiral shaft 331 is threadedly connected to the wire guide disc 31. Rotating the spiral shaft 331 can adjust the relative position of the positioning block 33 within the wire guide groove 311. A placement block 332 is slidably disposed within the wire guide groove 311. The placement block 332 is disposed on the side of the positioning block 33 away from the spiral shaft 331. A first elastic element 333 is disposed on the positioning block 33. The other end of the first elastic element 333 is connected to the placement block 332. When the positioning block 33 is adjusted, the placement block 332 can move synchronously under the action of the first elastic element 333. In this embodiment, the first elastic element 333 is a spring. A guide wheel 34 is rotatably mounted on the side of the placement block 332 away from the positioning block 33. The guide wheel 34 has a lead groove 341 that matches the wire core. The wire core can pass through the guide wheel 34 and be placed in the lead groove 341. The guide wheel 34 is always further away from the wire threading frame 2 than the positioning wheel 321, ensuring that when the wire core passes through and overlaps the positioning wheels 321 on both sides of the guide wheel 31, the guide wheel 34 can always maintain contact with the wire core and provide support.

[0028] During operation, the wire core passes through the lead cavity 22 and sequentially through the conductor reel 31 and two sets of fixing discs 32 on both sides of the conductor reel 31, while simultaneously overlapping with the positioning wheel 321 and the conductor wheel 34 corresponding to the lead cavity 22. Subsequently, multiple sets of spiral shafts 331 are rotated to adjust the positioning block 33 and the placement block 332 away from the threading frame 2, causing the conductor wheel 34 to push the wire core away from the threading frame 2 by a certain distance. During the movement of the wire core, the first elastic element 333 is compressed, which at the same time allows the wire core to maintain a constant initial tension, ensuring that the wire core is under stable force during the initial stranding, so that each strand of wire core is tightly attached at the stranding point, avoiding slack that would cause gaps between the wire cores, thereby forming a round conductor with a uniform structure and consistent outer diameter.

[0029] like Figures 4-6 and Figures 8-9 As shown, the support adjustment assembly 4 includes a support block 41 rotatably mounted on the conductor reel 31. An adjustment block 42 is slidably mounted on one end of the support block 41. One end of the adjustment block 42 is connected to a second elastic element 421, and the other end of the second elastic element 421 is connected to the support block 41. The initial position of the adjustment block 42 can be controlled by the second elastic element 421. In this embodiment, the second elastic element 421 is set as a spring. A pressure roller 43 is rotatably mounted on the side of the adjustment block 42 away from the second elastic element 421. The pressure roller 43 is located on the side of the conductor reel 31 away from the threading hole 21. During twisting, the pressure roller 43 is always located on the side of the conductor wheel 34 away from the threading frame 2, and the pressure roller 43 cooperates with the conductor wheel 34 and can contact it to limit the position of the wire core.

[0030] A third elastic element 411 is provided at the pivot of the support block 41. The other end of the third elastic element 411 is connected to the wire tray 31. In the initial state, under the action of the third elastic element 411, the adjusting block 42 can be kept horizontal, and the moving direction of the adjusting block 42 is perpendicular to the moving direction of the placement block 332. At this time, one end of the adjusting block 42 is inserted into the wire groove 311, and the width of the end of the adjusting block 42 inserted into the wire groove 311 is less than the width of the wire groove 311. In this embodiment, the third elastic element 411 is set as a torsion spring. The end of the wire groove 311 away from the wire threading frame 2 is provided with a constriction 312. The width of the constriction 312 is less than the width of the wire groove 311, and the width of the constriction 312 is greater than the width of the wire core. The width of the end of the adjusting block 42 inserted into the wire groove 311 is greater than the width of the constriction 312, so that the adjusting block 42 can be limited by the constriction 312. At the same time, the adjusting block 42 can block the position of the constriction 312 and keep the third elastic element 411 under force.

[0031] When the wire core needs to be overlapped on the guide wheel 34, the support block 41 is rotated to gradually slide out of the guide groove 311. At this time, the constriction 312 opens and the third elastic element 411 is subjected to increased force. Then, the wire core is directly placed into the guide wheel 34 in the guide groove 311 from the constriction 312 position. After the wire core is placed, the support block 41 is released. The support block 41 rotates in the opposite direction under the drive of the third elastic element 411 and is inserted back into the guide groove 311, sealing the constriction 312. This achieves rapid insertion and overlap of the wire core, saving threading and downtime. At this time, the first elastic element 333 is compressed, and the wire core maintains a certain initial tension. During the reverse rotation of the support block 41, the pressure roller 43 begins to contact the guide wheel 34 and compress the second elastic element 421. At this time, the wire core is limited by the joint action of the pressure roller 43 and the guide wheel 34, which can adapt to different wire diameters, limit wire deviation, and prevent wire skipping. Since the guide wheel 34 is always located on the side of the positioning wheel 321 away from the wire threading frame 2, when the pressure wheel 43 and the guide wheel 34 come into contact, the pressure wheel 43 can contact the wire core and squeeze and twist the wire core, applying appropriate pressure to the wire core to avoid wire skipping or uneven tension when the wire core is running at high speed.

[0032] By squeezing and twisting the wire core with the pressure roller 43, the path length of the wire core between the corresponding positioning rollers 321 on both sides of the conductor reel 31 is increased. During wire core stranding, the threading frame 2 rotates. Under the action of centrifugal force and the third elastic element 411, the support block 41 always blocks and tightly adheres to the constriction 312. At this time, the wire core maintains a certain tension under the action of the first elastic element 333, the pressure roller 43, and the centrifugal force. Since the wire core tension is unstable, when the tension of a certain wire core increases, the force on the first elastic element 333 increases, and the conductor roller 34 gradually moves closer to the threading frame 2, releasing the length of the wire core between the two sets of corresponding positioning rollers 321, thereby assisting in adjusting and reducing the tension. At this time, the pressure roller 43 begins to move closer to the conductor reel 31, the force on the second elastic element 421 decreases, and the synchronous force applied to the wire core by the pressure roller 43 decreases, further adjusting and reducing the wire core tension to avoid excessive wire core tension leading to breakage or affecting the cable stranding quality. When the tension of a certain wire core decreases, the force on the first elastic element 333 decreases, causing the conductor wheel 34 to gradually move away from the cable threading frame 2. This further lengthens the wire core between the two sets of corresponding positioning wheels 321, thereby assisting in adjusting and increasing the tension. At this time, the pressure wheel 43 begins to move away from the conductor reel 31, the force on the second elastic element 421 increases, and the pressure applied to the wire core by the pressure wheel 43 increases synchronously, further squeezing and twisting the wire core and increasing the wire core tension, thus achieving real-time dynamic adjustment of the wire core tension. Furthermore, since the pressure wheel 43 squeezes and twists the wire core before stranding, it initially releases the internal stress of the wire core, which helps to make the wire core stranding tighter, resulting in better product consistency and avoiding irregular cable formation caused by large internal stress in the wire core during stranding.

[0033] like Figure 4 and Figure 7As shown, the limiting protection component 5 includes a limiting block 51 slidably disposed within the lead wire groove 341. Multiple sets of limiting blocks 51 are evenly arranged, and the limiting blocks 51 can reciprocate to slide closer to or further away from the shaft of the guide wheel 34. The wire core passing through the guide wheel 34 can contact the limiting block 51. A spring piece 52 is provided on the side of the limiting block 51 near the shaft of the guide wheel 34. The other end of the spring piece 52 is connected to the inside of the lead wire groove 341. The spring piece 52 can push the limiting block 51 away from the shaft of the guide wheel 34. The elastic force of the spring piece 52 is less than the force exerted on the limiting block 51 when the wire core is normally twisted, so as to ensure that the limiting block 51 is fully retracted into the lead wire groove 341 during normal operation.

[0034] Because multiple sets of wire cores need to be threaded, after one set of wire cores is threaded, the pressure roller 43 contacts the guide roller 34 and limits the wire core. At this time, the limiting block 51, pushed by the spring piece 52, pushes the wire core onto the pressure roller 43, achieving initial clamping and limiting of the wire core. This prevents the wire cores from being loose and overlapping when threading multiple sets of wire cores, thus avoiding wire tangling. When the wire cores are twisted, the wire cores are under tension and compress the first elastic element 333. At this time, the spring piece 52 is compressed and the limiting block 51 in contact with the wire core is completely retracted into the lead groove 341, avoiding affecting the normal movement and twisting of the wire cores. If the wire core breaks due to excessive tension, the spring 52 can drive the limit block 51 to pop out quickly and push the broken part of the wire core onto the pressure roller 43 to clamp and limit it, preventing the wire core from getting stuck or tangled due to sudden wire breakage. At the same time, it avoids the problem of the wire core being thrown out quickly under the action of centrifugal force, which could endanger the safety of workers and damage the threading equipment. It also makes it easier for workers to quickly handle the broken wire core and re-thread and position it.
