Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically a cable stranding machine with eccentricity compensation function. Background Technology

[0002] A stranding machine is a type of mechanical equipment that can be widely used to strand various soft / hard conductor wires. It is a core piece of equipment in the field of wire and cable and electronic wire manufacturing. Its core function is to spirally wind multiple metal single wires (copper, aluminum, alloy wires, etc.) into a whole stranded conductor / core according to a preset stranding pitch, direction and layers, thereby improving the flexibility and tensile strength of the wire, optimizing conductivity stability and reducing signal interference.

[0003] In the existing cable stranding machine, when the amount of wire on the pay-off reel decreases during cable preparation, the center of gravity of the traction will shift. Since it does not have an eccentricity compensation function, it affects the quality of stranding. Furthermore, the single strand of cable cannot rotate to improve the clamping effect. At the same time, during the cable pay-off process, the straightening and softening components are mostly fixed, which increases the friction between the cable and the components, causing the cable surface to heat up and be damaged. Summary of the Invention

[0004] The purpose of this invention is to provide a cable stranding machine with eccentricity compensation function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: the stranding machine includes a support unit, a clamping unit, and an unwinding unit, wherein the unwinding unit is mounted on the support unit via the clamping unit; The unwinding unit includes a center of gravity compensation component, a wire feeding component, a straightening and softening component, a cooling component, and an unwinding component; The pressing unit is provided with a center of gravity compensation component, the center of gravity compensation component is provided with an unwinding component and a wire feeding component, and the wire feeding component is provided with a straightening and softening component and a cooling component. The center of gravity compensation assembly includes a fixed plate, a carrier plate, a drive motor, a lead screw, a sliding plate, an electric push rod, and a top plate; The clamping unit is symmetrically equipped with a fixing plate, on which a carrier plate is slidably mounted. An unwinding assembly and a wire feeding assembly are mounted on the carrier plate. The clamping unit is equipped with a drive motor, on which a lead screw is mounted. A sliding plate is slidably mounted on the lead screw and connected to the carrier plate. Electric push rods are mounted on both sides of the sliding plate perpendicular to the fixing plate, and top plates are mounted on the electric push rods. A pressure sensor is mounted on the unwinding drum of the unwinding assembly, and the pressure sensor is electrically connected to the drive motor and the electric push rods.

[0006] When the cable is twisted, as the amount of cable on the unwinding drum of the unwinding assembly decreases, the traction pressure on the pressure sensor on the unwinding drum gradually decreases. At this time, the pressure sensor can control the drive motor to run, which drives the slide plate to move through the lead screw. This allows the carrier plate to move synchronously with the unwinding assembly, achieving automatic compensation of the traction center of gravity and ensuring its stability. After the slide plate moves, the electric push rod can be activated to make the top plate fit tightly against the fixed plate, thus ensuring the stability of the carrier plate after dynamic balance adjustment. At the same time, the clamping unit can realize the self-rotation of a single strand of cable before twisting, which can improve the helical torque of the cable. The unwinding assembly can drive the straightening and softening assembly to move evenly back and forth. The cooling assembly can also cool the straightening and softening assembly, which can prevent the guide rollers in the straightening and softening assembly from causing the cable to heat up and oxidize.

[0007] As a preferred technical solution, the support unit includes a base and a vertical plate, the vertical plate is fixedly installed on the base, and a clamping component is provided on the vertical plate; The clamping assembly includes a geared motor, a drive wheel, drive teeth, a transmission wheel, a transmission belt, and driven teeth; A geared motor is installed on the vertical plate, and a drive wheel is mounted on the geared motor. A drive tooth is mounted on the side of the vertical plate away from the geared motor via a rotating shaft. A transmission wheel is mounted on the end of the rotating shaft away from the drive tooth. A transmission belt is fitted onto the transmission wheel and the drive wheel. Multiple driven teeth are rotatably mounted on the side of the vertical plate near the drive tooth, and all of the multiple driven teeth mesh with the drive tooth. A center of gravity compensation component is provided on the side of the driven teeth away from the vertical plate.

[0008] When the unwinding unit is running, the drive gear can be rotated by starting the geared motor, driven by the pulleys of the drive wheel, transmission wheel and transmission belt. Then, through the meshing of the drive gear and the driven gear, the driven gear can drive the entire unwinding unit to rotate during the rotation. This allows the single strand of cable to rotate before stranding, which helps to increase the spiral torque of the cable and improve the tightness of the cable after stranding.

[0009] As a preferred technical solution, the wire feeding assembly includes wire feeding transmission teeth, a fixed seat, a reduction gearbox, wire feeding driven teeth, a drive chain, a driving chain tooth, a driven chain tooth, a transmission chain, a passageway, a crossbar, a slide, a limiting track, a connecting column, and rollers. The unwinding assembly has a wire feeding drive gear mounted on its rotating shaft, and a fixed seat mounted on the unwinding assembly. A reduction gearbox is mounted on the fixed seat near the wire feeding drive gear. A wire feeding driven gear is mounted on the input end of the reduction gearbox. A drive gear chain is fitted onto the wire feeding drive gear and the wire feeding driven gear. A drive chain tooth is mounted on the output end of the reduction gearbox. A driven chain tooth is rotatably mounted on the other end of the fixed seat away from the reduction gearbox. A transmission gear chain is fitted onto the drive chain tooth and the driven chain tooth. A crossbar is fixedly mounted on the fixed seat. A slide block is slidably mounted on the crossbar. A straightening and softening assembly and a cooling assembly are mounted on the top of the slide block. A motion switching component is provided on the slide block. The motion switching component cooperates with the transmission gear chain. A limit track is mounted on the fixed seat. Two sets of connecting columns are symmetrically mounted on the slide block. Rollers are rotatably mounted on the two sets of connecting columns. The two sets of rollers are respectively located above and below the limit track and are in rolling engagement.

[0010] When the cable passes through the straightening and softening assembly and is twisted, the rotating shaft of the unwinding assembly can drive the unwinding drive teeth to rotate synchronously. Driven by the unwinding drive teeth, the driven unwinding teeth, and the drive tooth chain, the gearbox can drive the drive chain teeth to rotate. Then, through the tooth chain transmission formed by the drive chain teeth, the driven chain teeth, and the drive tooth chain, the continuous rotation of the drive tooth chain can be achieved. At this time, since the slide can slide on the crossbar, through the cooperation of the motion switching component and the drive tooth chain, the slide can reciprocate along the crossbar, thereby achieving synchronous reciprocating movement of the straightening and softening assembly driven by the slide. This is beneficial for the straightening and softening assembly to move accordingly as the cable is unwound, and can reduce the friction between the cable and the straightening and softening assembly.

[0011] As a preferred technical solution, the motion switching component includes a slide rail and a gear plate; The bottom of the slide block is equipped with a slide rail, on which two toothed plates are slidably mounted. Touch controllers are installed on both sides of the slide block, and these controllers are electrically connected to the slide rail. Initially, a single toothed plate engages with the transmission chain, allowing the rotation of the transmission chain to move the slide block laterally. When the slide block moves to one side of the fixed seat, the touch controller on the slide block contacts the fixed seat, controlling the slide rail to move synchronously, causing one toothed plate to disengage from the transmission chain and the other toothed plate to engage with it. This allows the slide block to reset and move under the drive of the transmission chain. This cycle repeats, and the reciprocating movement of the slide block can be achieved through the periodic rotation of the transmission gears.

[0012] As a preferred technical solution, the cooling component includes an electric lifting rod, a cooling pipe, a height detector, a chamber, a miniature fan, and an air outlet; A control component is installed at the rotation shaft of the unwinding assembly. An electric lifting rod is mounted on the slide, and a cooling tube is mounted on the electric lifting rod. A height detector is mounted on the cooling tube, and a chamber is provided inside the cooling tube. Multiple air vents are opened on the side of the chamber near the straightening and softening assembly, and multiple miniature fans are installed on the side of the chamber away from the air vents. A cooling adjustment component is provided at the air vents. By activating the electric lifting rod to raise the cooling tube, and after the height of the straightening and softening assembly is detected by the height detector, the electric lifting rod can drive the cooling tube to move until it is level with the straightening and softening assembly. When the unwinding assembly unwinds, the rotation shaft of the unwinding assembly drives the control component to operate, and the control component can activate the miniature fans to achieve cooling of the straightening and softening assembly. At the same time, the cooling effect on the straightening and softening assembly can be controlled by the cooling adjustment component according to the unwinding speed of the unwinding assembly.

[0013] As a preferred technical solution, the control component includes a turntable, an isolation pad, a rotating column, a cutting plate, a cover, a magnetic plate, a conductive column, and a current sensor; A turntable is installed at the end of the rotating shaft of the unwinding assembly. An isolation pad is installed at the center of the turntable, and a rotating column is installed on the isolation pad. Multiple cutting plates are installed in a circumferential array on the side wall of the rotating column. A cover is fixedly installed at the rotating shaft of the unwinding assembly. Two magnetic plates are symmetrically installed inside the cover, and a conductive column is rotatably installed on the cover. The conductive column is connected to the end of the rotating column away from the isolation pad. A current sensor is installed on the conductive column and is electrically connected to the micro fan. When the rotating shaft of the unwinding assembly rotates, the rotating shaft can drive the turntable to rotate synchronously. During the rotation of the turntable, the rotating column can drive the cutting plates to rotate, thereby cutting the magnetic lines between the two magnetic plates. The induced current can then enter the current sensor through the rotating column and the conductive column. The current intensity detected by the current sensor can control the operating power of the micro fan to be increased accordingly, thus controlling the operating power of the micro fan according to the change of the unwinding speed.

[0014] As a preferred technical solution, a ball bearing is rolled and fitted at the end of the conductive post near the rotating post. The ball bearing is in contact with the rotating post. Since the ball bearing can roll, it can ensure the stable connection between the rotating post and the conductive post while avoiding wear between the conductive post and the rotating post.

[0015] As a preferred technical solution, the cooling adjustment component includes a fixed column, a baffle, a worm gear ring, a linkage plate, a worm, and a micro motor; The air vents are located at the port of the chamber and are equipped with multiple fixed columns arranged in a circular array. Each of the fixed columns is rotatably mounted with a baffle. A worm gear ring is rotatably mounted at the port of the chamber. The inner diameter of the worm gear ring and the baffle are connected by a linkage plate. The linkage plate, the worm gear ring, and the baffle are all hinged. A worm is rotatably mounted inside the chamber and meshes with multiple worm gear rings. A micro motor is mounted on the cooling tube and drives the worm to rotate. An angle sensor is mounted on the worm gear rings, and the micro motor is electrically connected to a current sensor and an angle sensor. In the initial state, the shutter structure formed by the multiple baffles is annular, with the central hole being the smallest.

[0016] When the unwinding speed of the unwinding assembly increases, the induced current detected by the current sensor increases. At this time, the current sensor can control the operation of the micro motor, which drives the worm to rotate. Through the meshing of the worm and the worm wheel ring, the worm wheel ring can rotate. The angle sensor controls the worm wheel ring to rotate to the corresponding angle and then stops rotating based on the intensity of the induced current. During the rotation of the worm wheel ring, the baffle can be driven to rotate through the linkage plate, thereby controlling the central hole of the shutter structure to increase the air volume of the air outlet, enhancing the cooling effect on the correction and softening assembly, and realizing the corresponding increase in the air volume of the air outlet according to the change of unwinding speed.

[0017] As a preferred technical solution, the clamping unit further includes a support frame and a pulley seat. The support frame is installed on the side of the vertical plate near the drive teeth. The pulley seat and the twisting unit are installed on the support frame. The winding unit is slidably installed on the base.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This application can automatically compensate for the traction center of gravity by means of a pressure sensor as the amount of wire on the unwinding drum of the unwinding assembly decreases, thereby ensuring the stability of the traction center of gravity.

[0019] 2. This application can control the unwinding unit to rotate through the clamping unit, thereby enabling the single-strand cable to rotate before stranding, which is beneficial to improving the spiral torque of the cable and improving the tightness of the cable after stranding.

[0020] 3. The cable feeding component designed in this application facilitates the displacement of the straightening and softening component as the cable is unwound, thereby reducing friction between the cable and the straightening and softening component.

[0021] 4. The cooling components in this application can control the operating power of the micro fan according to the change in unwinding speed, and can also increase the air volume of the air outlet accordingly according to the change in unwinding speed. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Example: Figures 1-10 As shown, the present invention provides a technical solution for a cable stranding machine with eccentricity compensation function. The stranding machine includes a support unit 1, a clamping unit 2 and an unwinding unit 3. The unwinding unit 3 is installed on the support unit 1 through the clamping unit 2. The unwinding unit 3 includes a center of gravity compensation component 6, a wire unwinding component 7, a straightening and softening component 8, a cooling component 9, and an unwinding component 10; The pressing unit 2 is provided with a center of gravity compensation component 6, the center of gravity compensation component 6 is provided with an unwinding component 10 and a wire feeding component 7, and the wire feeding component 7 is provided with a straightening and softening component 8 and a cooling component 9. The twisting unit 4, winding unit 5, straightening and softening component 8, and unwinding component 10 in this application are all existing technologies, therefore, they will not be described in detail in the specification. The center of gravity compensation assembly 6 includes a fixed plate 601, a carrier plate 602, a drive motor 603, a lead screw 604, a sliding plate 605, an electric push rod 606, and a top plate 607. A fixed plate 601 is symmetrically arranged on the pressing unit 2. A carrier plate 602 is slidably installed on the fixed plate 601. An unwinding assembly 10 and a wire feeding assembly 7 are arranged on the carrier plate 602. A drive motor 603 is arranged on the pressing unit 2. A lead screw 604 is installed on the drive motor 603. A slide plate 605 is slidably installed on the lead screw 604. The slide plate 605 is connected to the carrier plate 602. Electric push rods 606 are installed on both sides of the slide plate 605 perpendicular to the fixed plate 601. A top plate 607 is installed on the electric push rods 606. A pressure sensor is arranged on the unwinding drum of the unwinding assembly 10. The pressure sensor is electrically connected to the drive motor 603 and the electric push rods 606.

[0026] When the cable is twisted, as the amount of cable on the unwinding drum of the unwinding assembly 10 decreases, the traction pressure on the pressure sensor on the unwinding drum gradually decreases. At this time, the pressure sensor can control the drive motor 603 to run, which drives the slide plate 605 to move through the lead screw 604. This allows the carrier plate 602 to move synchronously with the unwinding assembly 10, achieving automatic compensation of the traction center of gravity and ensuring the stability of the traction center of gravity. After the slide plate 605 moves, the electric push rod 606 can be activated to drive the top plate 607 to fit tightly against the fixed plate 601, thereby ensuring the stability of the carrier plate 602 after dynamic balance adjustment. At the same time, the clamping unit 2 can realize the self-rotation of a single cable before twisting, which can improve the spiral torque of the cable. The unwinding assembly 7 can drive the straightening and softening assembly 8 to move evenly back and forth. The cooling assembly 9 can also cool the straightening and softening assembly 8, which can prevent the guide rollers in the straightening and softening assembly 8 from causing the cable to heat up and oxidize.

[0027] The support unit 1 includes a base 101 and a vertical plate 102. The vertical plate 102 is fixedly installed on the base 101, and a clamping component 2 is provided on the vertical plate 102. The clamping assembly 2 includes a geared motor 201, a drive wheel 202, a drive gear 203, a transmission wheel 204, a transmission belt 205, and a driven gear 206; A geared motor 201 is installed on the vertical plate 102, and a drive wheel 202 is mounted on the geared motor 201. A drive gear 203 is mounted on the side of the vertical plate 102 away from the geared motor 201 via a rotating shaft. A transmission wheel 204 is mounted on the end of the rotating shaft away from the drive gear 203. A transmission belt 205 is sleeved on the transmission wheel 204 and the drive wheel 202. Multiple driven gears 206 are rotatably mounted on the side of the vertical plate 102 near the drive gear 203. All the driven gears 206 mesh with the drive gear 203. A center of gravity compensation component 6 is provided on the side of the driven gears 206 away from the vertical plate 102.

[0028] When the unwinding unit 3 is running, by starting the geared motor 201, the drive gear 203 can be rotated under the drive of the pulleys of the drive wheel 202, transmission wheel 204 and transmission belt 205. Then, through the meshing of the drive gear 203 and the driven gear 206, the driven gear 206 can drive the entire unwinding unit 3 to rotate during the rotation process. This enables the single strand of cable to rotate before stranding, which is beneficial to improve the spiral torque of the cable and can improve the tightness of the cable after stranding.

[0029] The wire feeding assembly 7 includes a wire feeding transmission gear 701, a fixed base 702, a reduction gearbox 703, a wire feeding driven gear 704, a drive chain 705, a driving chain gear 706, a driven chain gear 707, a transmission chain 708, a passageway 709, a crossbar 710, a slide 711, a limiting track 712, a connecting column 713, and a roller 714. A wire unwinding drive gear 701 is mounted on the rotating shaft of the unwinding assembly 10, and a fixed base 702 is mounted on the unwinding assembly 10. A reduction gearbox 703 is mounted on one end of the fixed base 702 near the wire unwinding drive gear 701. A wire unwinding driven gear 704 is mounted on the input end of the reduction gearbox 703. A drive chain 705 is fitted on the wire unwinding drive gear 701 and the wire unwinding driven gear 704. A drive chain tooth 706 is mounted on the output end of the reduction gearbox 703. A driven chain tooth 707 is rotatably mounted on the other end of the fixed base 702 away from the reduction gearbox 703. A drive chain tooth 707 is fitted on the drive chain tooth 706 and the driven chain tooth 707. The device includes a transmission chain 708, a crossbar 710 fixedly mounted on a fixed base 702, a slide block 711 slidably mounted on the crossbar 710, a correction and softening component 8 and a cooling component 9 mounted on the top of the slide block 711, and a motion switching component that cooperates with the transmission chain 708. A limit track 712 is mounted on the fixed base 702, and two sets of connecting columns 713 are symmetrically mounted on the slide block 711. Rollers 714 are rotatably mounted on the two sets of connecting columns 713. The two sets of rollers 714 are located at the upper and lower parts of the limit track 712, respectively, and are in rolling engagement.

[0030] When the cable passes through the straightening and softening assembly 8 and is twisted, the rotating shaft of the unwinding assembly 10 can drive the unwinding drive gear 701 to rotate synchronously. Driven by the unwinding drive gear 701, the unwinding driven gear 704, and the drive chain 705, the reduction gearbox 703 can drive the driving chain gear 706 to rotate. Through the chain drive formed by the driving chain gear 706, the driven chain gear 706, and the drive chain 708, the drive chain 708 can rotate continuously. At this time, due to the slide 71... 1. It can slide on the crossbar 710. Through the cooperation of the motion switching component and the transmission gear chain 708, the slide 711 can reciprocate along the crossbar 710, thereby enabling the slide 711 to drive the straightening and softening component 8 to move back and forth synchronously. This is beneficial for the straightening and softening component 8 to move accordingly as the cable is unwound, which can reduce the friction between the cable and the straightening and softening component 8. Through the sliding cooperation between the roller 714 and the limit rail 712, the movement stability of the slide 711 can be guaranteed.

[0031] The motion switching components include a slide rail 715 and a toothed plate 716; A slide rail 715 is installed at the bottom of the slide block 711. Two toothed plates 716 are slidably mounted on the slide rail 715. A touch controller is installed on both sides of the slide block 711. The touch controller is electrically connected to the slide rail 715. In the initial state, a single toothed plate 716 meshes with the transmission chain 708, so that the rotation of the transmission chain 708 can drive the slide block 711 to move laterally. When the slide block 711 moves to one side of the fixed seat 702, the touch controller on the slide block 711 contacts the fixed seat 702. The touch controller can control the slide rail 715 to run, so that the slide rail 715 drives the two toothed plates 716 to move synchronously, so that the contacting toothed plate 716 disengages from the transmission chain 708, and the other toothed plate 716 contacts and meshes with the transmission chain 708. Thus, the slide block 711 can achieve a reset movement under the drive of the transmission chain 708. The reciprocating movement of the slide block 711 can be achieved by the periodic rotation of the transmission gear 708.

[0032] The cooling component 9 includes an electric lifting rod 901, a cooling pipe 902, a height detector 903, a chamber 904, a miniature fan 905, and an air outlet 906; A control component is provided at the rotating shaft of the unwinding assembly 10.

A cooling adjustment component is provided at the air vents 906. By activating the electric lifting rod 901... 1. Raise the cooling pipe 902. After the height of the straightening and softening component 8 is detected by the height detector 903, the electric lifting rod 901 can drive the cooling pipe 902 to move until it is level with the straightening and softening component 8. When the unwinding component 10 unwinds, the rotation shaft of the unwinding component 10 drives the control component to run. The control component can start the micro fan 905 to cool the straightening and softening component 8. At the same time, the cooling effect on the straightening and softening component 8 can be controlled by the cooling adjustment component according to the unwinding speed of the unwinding component 10.

A rotating column 909 is mounted on the isolation pad 908. Multiple cutting plates 910 are arranged in a circumferential array on the side wall of the rotating column 909. A cover 911 is fixedly mounted on the rotating shaft of the unwinding assembly 10. Two magnetic plates 912 are symmetrically mounted inside the cover 911. A conductive post 913 is rotatably mounted on the cover 911. The conductive post 913 is connected to the end of the rotating column 909 away from the isolation pad 908.

When the rotating shaft of the unwinding assembly 10 rotates, the rotating shaft can drive the turntable 907 to rotate synchronously. During the rotation of the turntable 907, the cutting plate 910 can be rotated through the rotating column 909 to achieve magnetic line cutting between the two magnetic plates 912. The induced current can be allowed to enter the current sensor 914 through the rotating column 909 and the conductive column 913. The current intensity detected by the current sensor 914 can control the operating power of the micro blower 905 to be increased accordingly, so as to control the operating power of the micro blower 905 according to the change of unwinding speed.

[0034] A ball bearing 915 is rolled and fitted at the end of the conductive post 913 near the rotating post 909. The ball bearing 915 is in contact with the rotating post 909. Since the ball bearing 915 can roll, it can ensure the stable connection between the rotating post 909 and the conductive post 913 while avoiding wear between the conductive post 913 and the rotating post 909.

Each fixed post 916 is rotatably mounted with a baffle 917. A worm gear ring 918 is rotatably mounted at the port of chamber 904. The inner diameter of the worm gear ring 918 and the baffle 917 are connected by a linkage plate 919. The linkage plate 919 is hinged to both the worm gear ring 918 and the baffle 917. A worm 920 is rotatably mounted inside chamber 904. The worm 920 meshes with multiple worm gear rings 918. A micro motor 921 is installed on the cooling tube 902. The micro motor 921 drives the worm 920 to rotate. An angle sensor is installed on the worm gear ring 918. The micro motor 921 is electrically connected to the current sensor 914 and the angle sensor. In the initial state, the shutter structure formed by multiple baffles 917 is ring-shaped, with the center hole being the smallest.

[0036] When the unwinding speed of the unwinding assembly 10 increases, the induced current detected by the current sensor 914 increases. At this time, the current sensor 914 can control the operation of the micro motor 921, which drives the worm gear 920 to rotate. Through the meshing of the worm gear 920 and the worm wheel ring 918, the worm wheel ring 918 can rotate. The angle sensor controls the worm wheel ring 918 to rotate to the corresponding angle and then stop rotating based on the intensity of the induced current. During the rotation of the worm wheel ring 918, the baffle 917 can be rotated through the linkage plate 919, thereby controlling the central hole of the shutter structure to increase the air volume of the air outlet 906, enhancing the cooling effect on the correction and softening assembly 8, and realizing the corresponding increase in the air volume of the air outlet according to the change of the unwinding speed.

[0037] The clamping unit 2 also includes a support frame 103 and a pulley seat 104. The support frame 103 is installed on the side of the vertical plate 102 near the drive tooth 203. The pulley seat 104 and the twisting unit 4 are installed on the support frame 103. The winding unit 5 is slidably installed on the base 101.

[0038] Working principle of the invention: When the cable is twisted, as the amount of cable on the unwinding drum of the unwinding assembly 10 decreases, the traction pressure on the pressure sensor on the unwinding drum gradually decreases. At this time, the pressure sensor can control the drive motor 603 to run, which drives the slide plate 605 to move through the lead screw 604. This allows the carrier plate 602 to drive the unwinding assembly 10 to move synchronously, achieving automatic compensation of the traction center of gravity, thereby ensuring the stability of the traction center of gravity. After the slide plate 605 moves, the electric push rod 606 can be activated to drive the top plate 607 to fit tightly against the fixed plate 601, thereby ensuring the stability of the carrier plate 602 after dynamic balance adjustment.

[0039] When the unwinding unit 3 is running, by starting the geared motor 201, the drive gear 203 can be rotated under the drive of the pulleys of the drive wheel 202, transmission wheel 204 and transmission belt 205. Then, through the meshing of the drive gear 203 and the driven gear 206, the driven gear 206 can drive the entire unwinding unit 3 to rotate during the rotation process. This enables the single strand of cable to rotate before stranding, which is beneficial to improve the spiral torque of the cable and can improve the tightness of the cable after stranding.

[0040] When the cable passes through the straightening and softening assembly 8 and is twisted, the rotating shaft of the unwinding assembly 10 can drive the unwinding transmission gear 701 to rotate synchronously. Driven by the unwinding transmission gear 701, the unwinding driven gear 704, and the drive chain 705, the reduction gearbox 703 can drive the driving chain gear 706 to rotate. Through the chain transmission formed by the driving chain gear 706, the driven chain gear 706, and the transmission chain 708, the transmission chain 708 can continuously rotate. At this time, since the slide 711 can slide on the crossbar 710, initially, a single toothed plate 716 meshes with the transmission chain 708, allowing the rotation of the transmission chain 708 to drive the slide 711 to move laterally. When the slide 711 moves to the fixed seat 702... When the cable is on one side, the touch controller on the slide 711 contacts the fixed seat 702. The touch controller can control the slide rail 715 to run, so that the slide rail 715 drives the two toothed plates 716 to move synchronously. This causes the toothed plate 716 to disengage from the transmission toothed chain 708, and the other toothed plate 716 to engage with the transmission toothed chain 708. This allows the slide 711 to move back to its original position under the drive of the transmission toothed chain 708. This cycle repeats, and the periodic rotation of the transmission gear 708 can achieve the reciprocating movement of the slide 711 along the crossbar 710. This allows the slide 711 to drive the straightening and softening component 8 to move back and forth synchronously. This is beneficial for the straightening and softening component 8 to move accordingly as the cable is unwound, and can reduce the friction between the cable and the straightening and softening component 8.

[0041] By activating the electric lifting rod 901 to raise the cooling pipe 902, and after the height of the straightening and softening component 8 is detected by the height detector 903, the electric lifting rod 901 can drive the cooling pipe 902 to move until it is level with the straightening and softening component 8. When the unwinding component 10 unwinds, the rotating shaft of the unwinding component 10 drives the control component to operate, and the control component can start the micro fan 905. At the same time, when the rotating shaft of the unwinding component 10 rotates, the rotating shaft can drive the turntable 907 to rotate synchronously. During the rotation of the turntable 907, the cutting plate 910 can be rotated through the rotating column 909 to achieve the cutting of the magnetic field line between the two magnetic plates 912. The induced current can enter the current sensor 914 through the rotating column 909 and the conductive column 913. The current intensity detected by the current sensor 914 can control the operating power of the micro fan 905 to be increased accordingly, so as to control the operating power of the micro fan 905 according to the change of the unwinding speed.

[0042] When the unwinding speed of the unwinding assembly 10 increases, the induced current detected by the current sensor 914 increases. At this time, the current sensor 914 can control the operation of the micro motor 921, which drives the worm gear 920 to rotate. Through the meshing of the worm gear 920 and the worm wheel ring 918, the worm wheel ring 918 can rotate. The angle sensor controls the worm wheel ring 918 to rotate to the corresponding angle and then stop rotating based on the intensity of the induced current. During the rotation of the worm wheel ring 918, the baffle 917 can be rotated through the linkage plate 919, thereby controlling the central hole of the shutter structure to increase the air volume of the air outlet 906, enhancing the cooling effect on the correction and softening assembly 8, and realizing the corresponding increase in the air volume of the air outlet according to the change of the unwinding speed.
