Description

Technical Field

[0001] This application relates to the field of cable stranding equipment technology, and in particular to a stranding equipment for cable production. Background Technology

[0002] Cable processing mainly includes processes such as wire drawing, annealing, stranding, insulation layer coating, and protective sheath coating. The stranding process involves twisting multiple cable cores into one strand. Existing stranding devices generally include a wire separating die, a wire paralleling die, and a stranding reel. The wire separating die has multiple wire separating holes along its circumference, the wire paralleling die has wire paralleling holes, and the stranding reel has multiple wire twisting holes along its circumference. Multiple cable cores pass through the wire separating holes, stranding holes, and wire paralleling holes in sequence along the wire entry direction. By rotating the stranding reel, the cable cores can be stranded.

[0003] An existing patent (publication number: CN222190359U) discloses a cable stranding device for cable production, including a base, a support plate on the upper surface of the base, a stranding roller rotatably mounted on the support plate, a stranding disc fixed on the outer wall of the stranding roller, and multiple threading holes arranged in a circular pattern on the stranding disc. Multiple partitions are fixed on the outer wall of the stranding roller, corresponding to the threading holes. A lower pad is located between two partitions on the outer wall of the stranding roller, and a fixing ring with threaded holes is located on the outer wall of the partition. This allows the user to pass multiple cables through the threading holes and position them between the lower pad and the arc-shaped block, enabling a cleaning brush on the inner wall to clean dust from the cable's outer surface. The user can also adjust the distance between the lower pad and the arc-shaped block by turning a handwheel to clean cables of different diameters.

[0004] However, in the above-mentioned scheme, it was found that during the stranding operation of the core wires, there is an angle between each core wire and the final cable, which causes the core wires to bend during stranding. The bent part comes into contact with the edge of the stranding drum and the paralleling drum, which can easily cause wear on the core wires, thus affecting the quality of the final cable. Utility Model Content

[0005] The purpose of this application is to provide a stranding device for cable production, which has the advantages of preventing the bent part of the core wire from rubbing against the edge of the stranding drum and the paralleling drum, thereby preventing wear of the core wire caused by the tilt angle generated during stranding, and solving the problems mentioned in the background art.

[0006] This application provides a stranding device for cable production, employing the following technical solution: It includes a stranding module and a paralleling module. The stranding module includes a first L-shaped plate, with a stranding disc rotatably connected to the inner wall of the first L-shaped plate. A stranding drum arranged at equal intervals is fixedly connected to the inner wall of the stranding disc. A fixing block arranged at equal intervals is fixedly connected to the right side of the stranding disc. A circular block is fixedly connected to the outer surface of each fixing block. A limiting groove is formed inside each circular block. A slider is slidably connected to the inner wall of each limiting groove. A sliding rod is fixedly connected to the inner wall of each slider. The outer surface of each sliding rod is slidably connected to the inner wall of the corresponding circular block. A spring is fixedly connected to the side of each slider that is close to each other. The other end of each spring is fixedly connected to the inner bottom wall of the corresponding limiting groove. A fixing seat is fixedly connected to the side of each sliding rod that is far from each other. A guide wheel is rotatably mounted on the outer surface of each fixing seat. The paralleling module includes a paralleling drum, with a wear-resistant ring fixedly connected to the inner wall of the paralleling drum.

[0007] By adopting the above technical solution, a stranding module is formed by setting a first L-shaped plate, a stranding reel, and a stranding drum. The first L-shaped plate and the stranding reel are rotatably connected to limit the movement of the stranding reel. Equally spaced fixing blocks are installed on the right side of the stranding reel to support and install the circular blocks. A limiting groove is formed inside the circular block, and a slider is installed on the inner wall of the limiting groove. The slider is slidably positioned on the inner wall of the limiting groove to limit its movement. A sliding rod is installed and fixed to the slider to limit its movement. The fixing seat and the sliding rod are then connected... The end of the rod is fixed, and a guide wheel is connected to the fixed seat so that the guide wheel can be located at the outlet position of the stranding drum. A spring is set between the slider and the limiting groove so that the spring can press against the slider, thereby allowing the guide wheel to contact the cable and push the cable open. A wear-resistant ring is set at the inlet position of the stranding drum so that when multiple core wires are formed into the final cable, the guide wheel and wear-resistant ring can prevent the surface of the core wires from rubbing against the edges of the stranding drum and the stranding drum, thereby preventing wear of the core wires caused by the tilt angle generated when the core wires are stranded into the cable.

[0008] Preferably, a servo motor is fixedly mounted on the upper surface of the first L-shaped plate, and a gear is fixedly connected to the output shaft of the servo motor.

[0009] By adopting the above technical solution, a servo motor is installed on the upper surface of the first L-shaped plate to support and install the servo motor. The gear is fixed to the output shaft of the servo motor and set as a fixed connection, so that the servo motor can drive the gear to rotate.

[0010] Preferably, a toothed ring is fixedly connected to the outer surface of the strand, and the toothed ring meshes with a gear.

[0011] By adopting the above technical solution, the toothed ring is installed on the outer surface of the stranding drum, and the surface of the toothed ring meshes with the surface of the gear. When the servo motor drives the gear to rotate, the meshing of the gear and the toothed ring causes the toothed ring to drive the stranding drum to rotate, thereby enabling the stranding drum to rotate and causing multiple core wires to coalesce into a cable.

[0012] Preferably, a mounting base is fixedly connected to the outer surface of the parallel cylinder, and two second guide blocks are fixedly connected to the bottom surface of the mounting base.

[0013] By adopting the above technical solution, an installation seat is installed on the outer surface of the parallel drum, so that the installation seat can support the parallel drum and fix the second guide block on the bottom surface of the installation seat, thereby realizing the installation of the second guide block.

[0014] Preferably, the inner wall of each second guide block is threaded with a second bolt, and the outer surface of each second bolt is threaded to the inner wall of the mounting base.

[0015] By adopting the above technical solution, the second bolt is installed on the inner wall of the second guide block and set as a threaded connection. The second bolt is also connected to the mounting base, so that when the operator rotates the second bolt, the second bolt can move vertically, thereby enabling the second bolt to move up and down along the longitudinal direction of the second guide block.

[0016] Preferably, the left side of the stranded wire module is provided with a wire splitting module, the wire splitting module includes a second L-shaped plate, the inner wall of the second L-shaped plate is rotatably connected to a rotating disk, the inner wall of the rotating disk is fixedly connected to an equidistantly arranged wire inlet tube, and a connecting pipe is fixedly connected between the rotating disk and the stranded wire plate.

[0017] By adopting the above technical solution, the wire distribution module is set on the left side of the stranded wire module. By installing a rotating disk on the inner wall of the second L-shaped plate, the inlet drum is limited. The second L-shaped plate, the inlet drum, and the rotating disk together form the wire distribution module. The wire distribution module allows multiple cable cores to pass through the inlet drum sequentially along the direction of wire entry. By installing a connecting pipe between the rotating disk and the stranded wire disc, the stranded wire disc and the rotating disk can rotate synchronously.

[0018] Preferably, a base plate is provided below the stranded wire module, and two sliding grooves are formed on the upper surface of the base plate. The outer surface of each second guide block is slidably connected to the inner wall of the corresponding sliding groove.

[0019] By adopting the above technical solution, a base plate is set below the stranded wire module, and two sliding grooves are fixed on the upper surface of the base plate to achieve the positioning of the sliding grooves. The outer surface of the second guide block is connected to the corresponding sliding groove to achieve the sliding connection and limit the second guide block. When the operator moves the second guide block to the designated position, the second guide block can be locked in the designated position by rotating the corresponding second bolt, thereby facilitating the adjustment of the lateral position of the stranded wire module.

[0020] Preferably, the inner wall of each groove is slidably connected with two first guide blocks, the upper surface of each first guide block is fixedly connected to the bottom surface of the corresponding first L-shaped plate and second L-shaped plate, the inner wall of each first guide block is threaded with a first bolt, and the outer surface of each first bolt is threadedly connected to the inner wall of the corresponding first L-shaped plate and second L-shaped plate.

[0021] By adopting the above technical solution, the first guide block is installed on the inner wall of the corresponding slide groove, and the first guide block and the slide groove are set as a sliding connection to realize the limiting of the first guide block. The upper surface of the first guide block is fixed to the bottom surface of the corresponding first L-shaped plate and second L-shaped plate, so that the first L-shaped plate and the second L-shaped plate can move along the direction of the slide groove through the first guide block. By setting the first bolt to connect the first guide block and the first L-shaped plate to the second L-shaped plate, the operator can lock the first guide block in the designated position when rotating the first bolt, thereby facilitating the operator to adjust the lateral position of the stranding module and the splitting module.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This cable production stranding equipment, by incorporating components such as a slider, spring, and guide wheel, limits the slider's position during the process of core wires passing through the stranding drum to form the final cable. A circular block and a limiting groove further restrict the slider's movement, and the spring presses the slider firmly against the drum, ensuring the slider, sliding rod, and fixed seat are tightly secured. At this point, the guide wheel contacts the surface of the core wire. Furthermore, a wear-resistant ring is installed at the inlet of the stranding drum to prevent the bent portions of the core wires from rubbing against the edges of the stranding and stranding drums when multiple core wires are formed into the final cable. This prevents wear on the core wires caused by the angle generated during stranding. A first guide block is fixed to the bottom surface of the corresponding first L-shaped plate and second L-shaped plate. A first bolt is connected to the first guide block, the first L-shaped plate and the second L-shaped plate, so that after the first guide block moves on the inner wall of the slide, rotating the first bolt can lock the stranded module and the splitter module. A second guide block is set on the bottom surface of the mounting base. A second bolt is connected to the second guide block and the mounting base. After the second guide block moves on the inner wall of the slide, rotating the second bolt can lock the parallel module, thereby facilitating the operator to adjust the lateral position of the stranded module, the splitter module and the parallel module.

When the servo motor 13 drives the gear 14 to rotate, the meshing of the gear 14 and the toothed ring 15 can drive the stranded coil 102 to rotate, thereby enabling the stranded coil 103 to rotate and causing multiple core wires to be fused into a cable.

By setting the first bolt 19 to the first guide block 18 and the first L-shaped plate 101 to the second L-shaped plate 201, when the operator rotates the first bolt 19, the first guide block 18 can be locked in the designated position, so as to facilitate the operator to adjust the lateral position of the stranded wire module 1 and the splitting module 2.

[0032] The implementation principle of this application embodiment is as follows: Before use, firstly, move the corresponding stranded wire module 1, splitter module 2, and paralleling module 3. Through the connection between the first guide block 18 and the second guide block 20 and the slide groove 17, the stranded wire module 1, splitter module 2, and paralleling module 3 can be moved to the designated position. Then, rotate the corresponding first bolt 19 and second bolt 21 to lock the stranded wire module 1, splitter module 2, and paralleling module 3. After adjusting the position of the stranded wire module 1, splitter module 2, and paralleling module 3, pass multiple core wires through the corresponding wire inlet spool 202, stranded wire spool 103, and paralleling wire spool 301. Then, start the servo motor 13 to drive the gear 14 to rotate. Through the connection between the gear 14 and the gear ring 15, the gear ring 15 can drive the stranded wire. The disc 102 rotates, and through the connection pipe 22, it is fixed to the stranding disc 102 and the rotating disc 203, so that multiple stranding drums 103 and the inlet drum 202 can rotate, so that multiple core wires can be finally formed into a cable. During the stranding process, a spring 9 is set between the slider 7 and the limiting groove 6, so that the spring 9 presses against the slider 7, thereby pressing the slide rod 8, the fixed seat 10 and the guide wheel 11. The guide wheel 11 lifts the corresponding core wire, and a wear-resistant ring 12 is set at the inlet position of the paralleling drum 301. Through the cooperation of the guide wheel 11 and the wear-resistant ring 12, the bending part of the core wire can be prevented from rubbing against the edge of the stranding drum 103 and the paralleling drum 301 during stranding, thereby preventing the wear of the core wire caused by the tilt angle generated during stranding.
