Description

Technical Field

[0001] This invention relates to the field of cable manufacturing, and in particular to a cable traction device and method for cable assembly. Background Technology

[0002] Cable manufacturing processes include conductor drawing and annealing, stranding and bundling, cabling and armoring, and traction and winding. Among these processes, cable cabling is a crucial step in cable production. After cabling, the cable needs to be pulled out and wound in a timely manner using a traction device to maintain the smoothness and uniformity of the cable cabling process. Therefore, the traction device is an indispensable piece of equipment in cable cabling.

[0003] For example, Chinese patent CN115472342B discloses a cable-forming machine and processing technology for composite cables. In the cable-forming process of this type of device, the cable and optical fiber are installed on the corresponding cable reel frame. The cable and optical fiber are pulled by the cable-forming mold corresponding to the stranding reel. Then, the cable and optical fiber are stranded in cooperation with the stranding reel and the cable-forming mold. During this process, the filler rope is stranded with the cable and optical fiber. After a certain period of operation, the stranded composite cable is wound onto the take-up frame by a traction device in the form of a double traction wheel for winding.

[0004] However, existing dual-traction wheel traction devices for cable winding, although they have good tensile characteristics, only have traction and conveying characteristics in one direction for the cable. When the cable is pulled out for winding, the take-up frame needs to reciprocate to wind the cable, which causes the cable to swing back and forth, resulting in greater friction between the cable and the traction device. This can easily cause the cable to be squeezed, deformed and worn, thus limiting the traction adaptability. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cable winding and traction device and method that can reduce the friction and extrusion deformation caused during the cable winding process and improve the quality of cable winding.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A cable forming and traction device includes a first housing, on which multiple sets of arc-shaped first slide rails are arranged concentrically from the inside out and are distributed in a fan shape. Each set of first slide rails has a first slide table slidably mounted on it. Each first slide table is driven by a first drive assembly to perform periodic reciprocating sliding at different speeds. Pairs of traction guide wheels are arranged on the first slide tables to form a cable traction channel. Each set of traction guide wheels is driven by a second drive assembly to clamp and traction the cable.

[0007] The first drive assembly includes multiple sets of driven gears, each set of driven gears being rotatably mounted inside the first housing. Each set of driven gears meshes with a corresponding driven rack. The upper end of the driven rack passes through a clearance groove in the first housing and is fixedly connected to the first slide. The multiple sets of driven gears are driven to rotate through a first linkage transmission mechanism.

[0008] The first linkage transmission mechanism includes a drive gear, which is rotatably mounted on the first housing. One side of the drive gear is driven by an adjacent driven gear through a first synchronous transmission mechanism; the other adjacent driven gears are driven by a second synchronous transmission mechanism. The other side of the drive gear meshes with a drive rack, which is slidably mounted in a sector-shaped slide rail of a sector-shaped disk. The track length of the sector-shaped slide rail is greater than the rack length of the drive rack. The drive rack is limited by stop blocks at both ends of the sector-shaped slide rail. The sector-shaped disk is driven to rotate reciprocally by a reciprocating drive structure.

[0009] The reciprocating drive structure includes a fixed sleeve fixed to a first housing, a reciprocating shaft rotatably mounted inside the fixed sleeve and fixedly connected to a sector disk; a fourth drive shaft rotatably mounted inside the reciprocating shaft and driven by a second motor; the fourth drive shaft has a closed-loop slide groove along its axial direction, the closed-loop slide groove being a closed-loop spiral structure; the reciprocating shaft has at least one set of reciprocating slide grooves along its axial direction, the reciprocating slide grooves being an intermittent spiral structure; the fixed sleeve has at least one set of limiting slide grooves along its axial direction, the limiting slide grooves being a straight structure; one end of a slide rod is slidably engaged with the limiting slide groove, the slide rod passes through the reciprocating slide groove and the other end is located in the closed-loop slide groove.

[0010] The diameter of the synchronous pulley in the second synchronous transmission mechanism gradually decreases from the inside to the outside.

[0011] The second drive assembly includes a second housing fixed on each first slide. A guide wheel transmission mechanism is provided inside the second housing. An input shaft is provided on one side of the second housing, and an output shaft is provided on the other side of the second housing. The input shaft and output shaft of each second housing are connected by the guide wheel transmission mechanism. The input shaft and output shaft of two adjacent sets of second housings are connected by a universal joint. A first motor and a set of fixedly arranged first slides are provided on the first housing near the cable traction inlet. The first motor drives the input shaft at the fixedly arranged first slide to rotate.

[0012] The guide wheel transmission mechanism includes a first drive shaft connected to the traction guide wheel, a second drive shaft arranged between the input shaft and the output shaft, a third drive shaft rotatably mounted inside the second drive shaft, and both ends of the third drive shaft extending out of the second drive shaft; a bevel gear pair is mounted at one end of the input shaft, and a second bevel gear is mounted at one end of the output shaft; a third bevel gear is mounted at one end of the second drive shaft, and a fourth bevel gear is mounted at the lower end of the third drive shaft; wherein, the second, third, and fourth bevel gears all mesh with the first bevel gear, and the bevel gear pair is driven by the first bevel gear through a fourth synchronous transmission mechanism; the second drive shaft and the third drive shaft are respectively connected to the corresponding first drive shaft through a set of third synchronous transmission mechanisms.

[0013] The outer wall of the output shaft is provided with a track-changing groove along the axial direction. The bushing is sleeved on the output shaft and slides in cooperation with the track-changing groove through the second sliding buckle. The bushing is rotatably mounted on the bushing. A lever is installed above the bushing. The lever drives a pair of guide wheels to move closer or further away.

[0014] The bushing has a side support guide rail arranged on its moving path. The side support guide rail slides in conjunction with the sleeve. The side support guide rail has at least one set of guide grooves inside, and a rotating groove is formed at the top of the guide groove. The bushing has at least one set of first sliding buckles on one side. The first sliding buckles slide along the guide groove to provide rotation limit for the bushing. When the bushing slides along the guide groove to the rotating groove, the rotation limit of the bushing is released.

[0015] A cable assembling and pulling method includes the following steps: Step 1: The formed cable is clamped and pulled by the guide wheel; Step 2: Based on the drive of the first drive component, drive each group of traction guide wheels to slide back and forth periodically at different speeds along the first slide rail track; based on the second drive component, drive each group of traction guide wheels to rotate in opposite directions and clamp the cable, providing traction guidance during the cable winding process, so that the cable tends to align with the cable winding position during the cable winding process. Step 3: When the guide wheel slides to the top, pause it briefly to allow time for the next round of cable winding.

[0016] This invention provides a cable traction device and method for cable bundling, which has the following technical advantages: 1) By setting up a drive component, each group of traction guide wheels is driven to perform periodic reciprocating drive, so that each group of traction guide wheels forms a variable fan-shaped traction channel, which moves synchronously with the cable reel, so that the cable always tends to align with the cable reel position, reducing the friction and compression deformation caused during the cable reeling process, and improving the cable cabling quality.

[0017] 2) By driving the reciprocating drive of each group of traction guide wheels through the drive components, each group of traction guide wheels has the ability to pause briefly when it moves to the top of the reciprocating motion, providing the time required for the next round of cable winding, so that the cable is initially wound tightly in the next round of winding, making the subsequent winding more compact.

[0018] 3) By using the clamping and rolling assembly to act on the opposing movement and synchronous rotation of the traction guide wheel, the traction guide wheel can clamp the cable itself while simultaneously rolling and pulling the cable. This reduces manual operation and improves operational safety. Furthermore, under the drive of the clamping and rolling assembly, the traction guide wheel always maintains pressure on the cable, making the cable transport more stable.

Detailed Implementation

[0041] like Figures 1-3 , Figure 17 As shown, a cable forming and traction device includes a first housing 1, which is generally fan-shaped. Multiple sets of first slide rails 2 are arranged from the inside to the outside on the first housing 1. The multiple sets of first slide rails 2 are all arc-shaped and concentric. A first slide table 3 is slidably installed on each set of first slide rails 2. Pairs of traction guide wheels 5 are arranged on the first slide table 3. The multiple sets of paired traction guide wheels 5 form a cable traction channel.

[0042] Inside the first housing 1, there is a first drive assembly. The first drive assembly drives each group of first slides 3 to slide back and forth periodically along the corresponding first slide rails 2 at different speeds, and then drives each guide wheel 5 to swing back and forth, forming a traction path in a "fan-shaped swing" state, so as to provide uniform force at each force point during the cable traction winding process, and pause briefly when the guide wheel 5 swings to the limit position. During the brief pause, the time required for the cable to be wound to a new layer of wiring after being wound to the top is met.

[0043] Specifically: the linear reciprocating sliding of the slide bar 1130 drives the sector disk 12 to swing back and forth, so that the stop blocks 19 at both ends of the sector disk 12 contact the active rack 13 in sequence, driving the active rack 13 to move back and forth. The meshing of the active rack 13 and the active gear 14 drives the driving force that drives the guide wheel 5 to move back and forth.

[0044] When the slide bar 1130 slides to the highest point on one side, the sector disk 12 swings to its maximum angle, causing the stop block 19 to no longer exert a pushing force on the drive rack 13. At this time, the guide wheel 5 swings to its limit position. Then, when the slide bar 1130 moves from one end to the other, it drives the sector disk 12 to rotate in the opposite direction. At this time, since the stop block 19 at the other end of the sector disk 12 is not in contact with the drive rack 13, no pushing force is applied to the drive rack 13 during this process. This allows the guide wheel 5 to pause briefly when it slides to its limit position. Only when the sector disk 12 drives the stop block 19 at the other end to contact the drive rack 13 will a pushing force be applied to the drive rack 13, generating a driving force to push the guide wheel 5 to swing in the opposite direction again. This driving state is then followed to realize the reciprocating swing of the guide wheel 5, and it has the ability to pause briefly when it swings to its limit position.

[0045] Traditional traction devices are fixed traction structures. When the cable reel works to reel in the cable, it does so in a spiral winding manner. As a result, when the cable swings back and forth around the outlet of the traditional traction device, a large sway angle is generated between the cable and the outlet of the traction device, which can easily lead to friction, compression and deformation.

[0046] In this invention, when the cable is pulled by the guide wheel 5, the first drive assembly acts independently on each group of first slides 3, causing each guide wheel 5 to slide periodically back and forth along the first slide rail 2, thereby keeping the cable in the guide wheel 5 in a "fan-shaped swing" traction state (e.g., Figure 17 As shown in the state diagrams a, b, and c), the cable tends to align with the position of the cable reel, reducing the swaying friction and squeezing force experienced during the cable traction and reeling process. This allows the swaying force of the cable to be evenly distributed among each guide wheel 5. Furthermore, when the guide wheel 5 sways to its highest point, it pauses briefly to provide the necessary time for the cable to be wound in a new spiral (when the cable is wound along the reel to the top, it is rewound along the top part. At this time, the cable needs to be wound once to ensure the tight follow-up winding of the subsequent cable).

[0047] like Figures 2-7 , Figures 19-21 As shown, in order to achieve the reciprocating oscillating movement and brief pause of the guide wheel 5, the first drive assembly includes multiple sets of driven gears 16. Each set of driven gears 16 can be rotatably installed in the first housing 1. The driven gear 16 meshes with the corresponding driven rack 7. The upper end of the corresponding first housing 1 has a clearance groove 6. The first slide 3 is fixedly connected to the corresponding driven rack 7.

[0048] Multiple sets of driven gears 16 are driven to rotate through a first linkage transmission mechanism. The first linkage transmission mechanism includes a second synchronous transmission mechanism 17. Adjacent driven gears 16 are all connected by transmission through the second synchronous transmission mechanism 17. The second synchronous transmission mechanism 17 includes a second synchronous pulley coaxially connected to the driven gear 16. A second transmission belt is wound around the adjacent second synchronous pulley. The second transmission belt is used as a driving source to drive each driven gear 16 to rotate in sequence.

[0049] like Figures 2-3 As shown, a drive gear 14 is installed on one side of a set of driven gears 16 near the center. The drive gear 14 is rotatably mounted on the first housing 1, and the drive gear 14 and the adjacent driven gears 16 are driven by a first synchronous transmission mechanism 15.

[0050] like Figure 4 As shown, a sector disk 12 is rotatably mounted on one side of the drive gear 14. A drive rack 13 that meshes with the drive gear 14 is slidably mounted on the edge of the sector disk 12. A sector slide rail 18 is also provided on the edge of the sector disk 12 to provide sliding for the drive rack 13. The track length of the sector slide rail 18 is greater than the rack length of the drive rack 13. Stop blocks 19 are provided at both ends of the sector slide rail 18 so that the drive acting on the drive rack 13 is generated when the stop blocks 19 contact the drive rack 13.

[0051] By controlling the sector disk 12 to swing back and forth along its axis, the sector slide rail 18 slides along the drive rack 13 during the swinging process, without generating a drive force on the drive rack 13. Only when the stop block 19 contacts the drive rack 13 does a driving force be generated on the drive rack 13, causing the drive rack 13 to mesh with the drive gear 14 for transmission. Then, through the first synchronous transmission mechanism 15, a driving force is generated on one of the driven gears 16. Subsequently, the other driven gears 16 rotate together under the drive of the second synchronous transmission mechanism 17, driving each guide wheel 5 to swing back and forth.

[0052] like Figure 3 As shown, preferably, the two adjacent sets of second synchronous pulleys are differential pulley structures, that is, the diameter of the second synchronous pulley in the second synchronous transmission mechanism 17 gradually decreases from the inside to the outside, forming each driven gear 16 driven at different speeds.

[0053] Because the combinations of each first slide table 3 and the first slide rail 2 result in different sliding lengths from the inside out within the same time period, by gradually decreasing the diameter of the second synchronous pulley from the inside out in the second synchronous transmission mechanism 17, the rotational speed of each driven gear 16 from the inside out increases sequentially. This drives each first slide table 3 from the inside out to slide on the first slide rail 2 at an increasing speed, thereby driving each guide wheel 5 to move synchronously in a reciprocating oscillating motion while maintaining a progressive fan-shaped movement (such as...). Figure 17 As shown in the state diagrams a, b, and c, the cable is pulled and wound in a smooth transition.

[0054] like Figure 1 As shown, preferably, the traction guide wheel 5 acting on the cable traction inlet (near the first motor 8) is set to a fixed state, and it does not swing back and forth with the swing of the subsequent traction guide wheel 5. The cable after cabling is introduced horizontally, so that when the traction device pulls the cable, its inlet is fixed and its outlet swings back and forth. The swing force during the cable winding process is evenly transmitted to each traction guide wheel 5, reducing the large-angle frictional resistance and squeezing deformation at its outlet end during the winding process.

[0055] The sector disk 12 is driven to rotate reciprocally by the reciprocating drive structure 11.

[0056] like Figures 5-7 , Figures 19-21 As shown, the reciprocating drive structure 11 includes a fixed sleeve 1110 arranged below the sector disk 12. The fixed sleeve 1110 is fixedly connected to the first housing 1. The fixed sleeve 1110 has a mounting hole inside. The reciprocating shaft 1160 is clearance-fitted with the mounting hole. The upper end of the reciprocating shaft 1160 is fixedly connected to the sector disk 12. At the same time, the reciprocating shaft 1160 has a mounting hole opened along the axial direction. The fourth drive shaft 1140 is clearance-fitted with the mounting hole of the reciprocating shaft 1160. The fourth drive shaft 1140 is driven by the second motor 10 fixedly installed below the first housing 1.

[0057] Furthermore, the fourth drive shaft 1140 has a closed-loop slide groove 1150 along its axial direction. The closed-loop slide groove 1150 has a closed-loop spiral structure. The reciprocating shaft 1160 has at least one set of reciprocating slide grooves 1170 along its axial direction. The reciprocating slide grooves 1170 have an intermittent spiral structure. The fixed sleeve 1110 has at least one set of limiting slide grooves 1120 along its axial direction. The limiting slide grooves 1120 have a straight structure. One end of the slide rod 1130 is slidably engaged with the limiting slide groove 1120. The slide rod 1130 passes through the reciprocating slide groove 1170 and the other end is located in the closed-loop slide groove 1150.

[0058] Using the second motor 10 as a drive source, the fourth drive shaft 1140 is driven to rotate, causing the closed-loop slide groove 1150 to rotate with the fourth drive shaft 1140. This pushes the slide rod 1130 to slide back and forth along the closed-loop slide groove 1150. Since the slide rod 1130 is limited by the limiting slide groove 1120, the rotational drive of the closed-loop slide groove 1150 on the slide rod 1130 is transformed into a vertical up-and-down linear drive. When the slide rod 1130 moves up and down in a reciprocating linear motion, since the slide rod 1130 passes through the reciprocating slide groove 1170, the reciprocating shaft 1160 will be driven to rotate back and forth, generating a reciprocating drive acting on the sector disk 12.

[0059] like Figure 4 As shown, the slide bar 1130 drives the reciprocating shaft 1160 to rotate clockwise, and the sector disk 12 rotates clockwise. Initially, the driving rack 13 is stationary. When a set of stop blocks 19 (denoted as a) of the sector disk 12 contacts the driving rack 13, the stop blocks 19 drive the driving rack 13 to rotate together, thereby driving the driving gear 14 to rotate. Through the first synchronous transmission mechanism 15, the second synchronous transmission mechanism 17, etc., the first slide table 3 is finally driven to swing to one side along the first slide rail 2. When the slide bar 1130 reaches the upper limit position and moves downward or reaches the lower limit position and moves upward, the sector disk 12 rotates clockwise. The disk 12 also begins to rotate counterclockwise. At this time, due to the gap between the other set of stop blocks 19 (represented by b) and the drive rack 13, the gap between the two forms a brief drive no-load period. When the sector disk 12 rotates counterclockwise, the drive rack 13 does not move, causing the first slide 3, the guide wheel 5, etc. to pause briefly. When the other set of stop blocks 19 (represented by b) contacts the drive rack 13, it drives the drive rack 13 to move in the opposite direction, generating a driving force that acts on the guide wheel 5 to swing in the opposite direction. Then, in this state, the guide wheel 5 is driven to reciprocate and pause briefly.

[0060] like Figure 1 , Figures 8-17 As shown, a second drive assembly is arranged above the first housing 1. The second drive assembly is used to drive the two pairs of traction guide wheels 5 on each first slide 3 to clamp the cable, and to traction drive the cable forward during the relative rotation of the two traction guide wheels 5.

[0061] The second drive assembly includes a second housing 4 fixed on each first slide 3. The second housing 4 is provided with a guide wheel transmission mechanism. An input shaft 20 is provided on one side of the second housing 4 and an output shaft 22 is provided on the other side of the second housing 4. The input shaft 20 and the output shaft 22 of each first slide 3 are connected by the guide wheel transmission mechanism. The guide wheel transmission mechanism simultaneously drives the two traction guide wheels 5 on the first slide 3 to move relative to each other.

[0062] The input shaft 20 and output shaft 22 between two adjacent sets of second housings 4 are connected by a universal joint 9, providing synchronous drive for the reciprocating swaying of each set of traction guide wheels 5. A first motor 8 is provided on the first housing 1 near the cable traction inlet. The first motor 8 is used as a drive source to drive the input shaft 20 and output shaft 22 near the cable traction inlet to rotate, which in turn drives the traction guide wheels 5 near the cable traction inlet to rotate in opposite directions. Furthermore, under the transmission of the universal joint 9, the other traction guide wheels 5 are driven to rotate synchronously in opposite directions. Since the traction guide wheels 5 reciprocate and sway when tractioning the cable, the universal rotation characteristics of the universal joint 9 and the telescopic transmission characteristics of the spline shaft 910 on one side of the universal joint 9 enable the combination of the universal joint 9 and the spline shaft 910 to have telescopic and swaying transmission characteristics as the traction guide wheels 5 reciprocate and sway, always acting as an integrated drive for each traction guide wheel 5.

[0063] like Figure 1 , Figures 8-12 As shown, the guide wheel transmission mechanism includes a first drive shaft 28 located below the traction guide wheel 5, a second drive shaft 32 arranged between the input shaft 20 and the output shaft 22, and a third drive shaft 34 rotatably mounted inside the second drive shaft 32, with both ends of the third drive shaft 34 extending out of the second drive shaft 32.

[0064] A bevel gear pair 21 is installed at one end of the input shaft 20, a second bevel gear 23 is installed at one end of the output shaft 22, a third bevel gear 33 is installed at one end of the second drive shaft 32, and a fourth bevel gear 35 is installed at the lower end of the third drive shaft 34. The second bevel gear 23, the third bevel gear 33, and the fourth bevel gear 35 all mesh with the first bevel gear 2120. The bevel gear pair 21 and the first bevel gear 2120 are driven by a fourth synchronous transmission mechanism 2110. When the input shaft 20 rotates, it drives the bevel gear pair 21 to rotate. The bevel gear pair 21 drives the fourth synchronous transmission mechanism 2110 to rotate, and the fourth synchronous transmission mechanism 2110 drives the first bevel gear 2120 to rotate. Then, the meshing transmission between the first bevel gear 2120 and the third bevel gear 33 and the fourth bevel gear 35 generates opposite driving forces acting on the second drive shaft 32 and the third drive shaft 34, causing the second drive shaft 32 and the third drive shaft 34 to rotate in opposite directions. The second drive shaft 32 is connected to a set of first drive shafts 28 through a set of third synchronous transmission mechanisms 29, and the third drive shaft 34 is connected to another set of first drive shafts 28 through a set of third synchronous transmission mechanisms 29. Each set of first drive shafts 28 is rotatably mounted on the second housing 4 and coaxially connected to a set of traction guide wheels 5. Since the second drive shaft 32 and the third drive shaft 34 rotate in opposite directions, the two sets of traction guide wheels 5 can achieve opposite rotation (rotation directions are opposite), and roll and pull the cable.

[0065] It should be noted that, due to the meshing of the first bevel gear 2120 and the second bevel gear 23, when the driving force of the input shaft 20 is transmitted to the bevel gear pair 21, the bevel gear pair 21 is driven by a reverse force. This force is transmitted to the first bevel gear 2120 through the fourth synchronous transmission mechanism 2110, causing the first bevel gear 2120 to reverse. Then, by utilizing the meshing of the first bevel gear 2120 and the second bevel gear 23, the reverse driving force is corrected, causing the second bevel gear 23 to rotate in the same direction. This causes the input shaft 20 and the output shaft 22 to rotate in the same direction. Subsequently, under the transfer drive of the universal joint 9, the next set of input shafts 20 and output shafts 22 are driven to rotate simultaneously. Through this transmission state, each traction guide wheel 5 is driven to rotate synchronously in opposite directions, acting on the multi-point rolling traction of the cable.

[0066] like Figure 11 , Figures 13-16 , Figure 18 As shown, the outer wall of the output shaft 22 is provided with a guide rail groove 2210 along the axial direction. The guide rail groove 2210 has a spiral structure. A bushing 31 is fitted on the output shaft 22. The inner wall of the bushing 31 is provided with a second sliding buckle 3120 protruding outward. The second sliding buckle 3120 is located in the guide rail groove 2210, so that the second sliding buckle 3120 can slide along the trajectory of the guide rail groove 2210. A sliding sleeve 27 is also rotatably installed on the outside of the bushing 31.

[0067] like Figure 16 As shown, the sliding sleeve 27 is rotatably connected to the bushing 31, and when the bushing 31 moves left and right, the sliding sleeve 27 moves left and right together with the bushing 31.

[0068] (1) When the output shaft 22 rotates and drives the variable track slide 2210 to rotate, the rotational motion of the output shaft 22 is converted into the linear motion of the bushing 31 under the cooperation of the variable track slide 2210 and the second sliding buckle 3120, so that the bushing 31 moves horizontally and drives the slide 27 to move (at this time, since the first sliding buckle 3110 at one end of the bushing 31 is located in the guide slide 3010 of the side support guide rail 30, the cooperation of the two forms a horizontal guide limit state, so that the bushing 31 only has horizontal force and will not rotate relative to the slide 27). During the movement of the slide 27, the closing and opening forces are applied to the arm force connecting rod 26, pushing the two sets of traction guide wheels 5 to close or open in opposite directions. (2) When the first sliding buckle 3110 slides from the guide groove 3010 to the rotating groove 3020, the cooperation between the first sliding buckle 3110 and the rotating groove 3020 makes the horizontal force on the bushing 31 disappear. At this time, the rotation of the output shaft 22 drives the bushing 31 to rotate synchronously (at this time, the cooperation between the changing track groove 2210 and the second sliding buckle 3120 forms a snap-fit ​​state, so that the output shaft 22 can drive the bushing 31 to rotate). By using the rotation connection between the bushing 27 and the bushing 31, the bushing 31 can rotate relative to the bushing 27 and always apply a horizontal force to the bushing 27.

[0069] like Figure 18 As shown, a column is fixed to the top of the sliding sleeve 27, and an arm force connecting rod 26 is installed at the column. The arm force connecting rod 26 includes a left connecting rod and a right connecting rod. One end of the left connecting rod and the right connecting rod are rotatably connected to the column, and the other end of the left connecting rod and the right connecting rod are rotatably connected to a second sliding table 25 respectively. The two sets of second sliding tables 25 are slidably arranged on the second slide rail 24. The second slide rail 24 has an arc-shaped structure and is coaxial with the second drive shaft 32 and the third drive shaft 34. In this way, when the two traction guide wheels 5 move in opposite directions, the transmission belt of the third synchronous transmission mechanism 29 is always kept taut. A first drive shaft 28 is installed on each set of second sliding tables 25. The first drive shaft 28 passes through the second slide rail 24 at the upper end of the second housing 4 and then installs the traction guide wheel 5.

[0070] In addition, a side support guide rail 30 is fixedly installed on the second housing 4. The side support guide rail 30 is slidably engaged with the sliding sleeve 27. Since the sliding sleeve 27 is rotatably connected to the bushing 31, the side support guide rail 30 guides and limits the sliding sleeve 27, so that the sliding sleeve 27 only has the ability to move horizontally and is not affected by the rotation of the bushing 31.

[0071] In addition, the side support guide rail 30 has a guide groove 3010 inside, and a rotating groove 3020 is formed at the top of the guide groove 3010. The bushing 31 also has a first sliding buckle 3110 on one side. The first sliding buckle 3110 can slide along the guide groove 3010 to provide rotation limit for the bushing 31. When it slides along the guide groove 3010 to the rotating groove 3020, the rotation limit of the bushing 31 is released.

[0072] When the output shaft 22 drives the variable track slide 2210 to rotate, and applies force to the second sliding buckle 3120 of the bushing 31, at the same time, the first sliding buckle 3110 on the bushing 31 is in the guide slide 3010, which guides and limits the bushing 31, so that the bushing 31 only has the ability to move horizontally. That is, when the output shaft 22 rotates, it can drive the bushing 31 to move horizontally. The bushing 31 drives the slide 27 to move. When the arm force linkage 26 on the slide 27 moves horizontally, it will drive the two sets of second slides 25 to move closer or further apart. When the two sets of second slides 25 move closer, the two guide wheels 5 move closer and can clamp the cable.

[0073] When the second sliding buckle 3120 slides to the top of the changing track groove 2210, the first sliding buckle 3110 transitions to the rotating groove 3020. The first sliding buckle 3110 can rotate and slide along the rotating groove 3020, that is, the bushing 31 can rotate relative to the side support guide rail 30. Since the second sliding buckle 3120 is located in the changing track groove 2210, the bushing 31 can rotate synchronously with the output shaft 22, so that the bushing 31 changes from horizontal movement to a state of synchronous rotation with the output shaft 22. At this time, the bushing 31 and the output shaft 22 rotate synchronously, and the sliding sleeve 27 remains stationary. This stops the opposing movement of the traction guide wheel 5, so that the two adjacent traction guide wheels 5 maintain a fixed movement and act on the self-clamping of the cable.

[0074] It should be noted that when the second sliding buckle 3120 is at the top of the track-changing slide 2210 and rotates synchronously with it, the rotation drive of the track-changing slide 2210 always applies a driving force to the second sliding buckle 3120 that tends to move horizontally. This ensures that when the bushing 31 changes from horizontal movement to rotational movement, it always has a force state that tends to move horizontally, so that the clamping force of the guide wheel 5 on the cable is maintained in a stable clamping force state.

[0075] When in use (working), when the cable passes the guide roller 5, the guide roller 5 is driven to move in opposite directions based on the drive of the clamping and rolling assembly to clamp the cable. At the same time, the guide roller 5 is driven to rotate in opposite directions to roll and pull the cable to the winding frame for winding.

[0076] While pulling and winding the cable, the drive components also drive each guide wheel 5 to reciprocate and swing in a progressive fan-shaped motion, so that its traction outlet tends to align with the position of the cable coil. This allows the cable to be pulled and wound in a smooth transition, avoiding excessive cable swing angle that could cause friction, compression, deformation, and loss of roundness. Furthermore, when the guide wheel 5 swings to its highest point, it can pause briefly to provide the necessary time for the next round of spiral winding of the cable, making the cable coil arrangement more compact.

[0077] A cable assembling and pulling method includes the following steps: Step 1: The formed cable is clamped and pulled by the guide wheel 5.

[0078] Step 2: Based on the drive component, drive each group of traction guide wheels 5 to slide back and forth periodically at different speeds along the track direction of the first slide rail 2, providing traction guidance during the cable winding process, so that the cable is always aligned with the cable winding position during the traction process.

[0079] Step 3: When the guide wheel 5 slides to the top, pause the guide wheel 5 briefly to allow time for a new round of cable winding.
