Description

Technical Field

[0001] The invention relates to the technical field of cable stranding machines, and in particular to a tubular stranding machine. Background Art

[0002] A wire stranding machine is a mechanical device that can be used to twist various soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of the wire. According to the stranding method, wire stranding machines can generally be divided into single stranding machines, pair stranding machines, high-speed stranding machines, back-twisting machines, cage stranding machines, frame stranding machines, tubular stranding machines and disc stranding machines. Tubular stranding machines generally include a tube cage and a wire reel rack that is rotatably connected to the tube cage, on which a wire reel is installed, and a single strand of wire is wound on the wire reel.

[0003] For example, the patent with announcement number CN211604799U discloses a tubular stranding machine, in which a mounting cavity is provided in the tubular body of the tubular stranding machine, a wire drum mounting frame is provided in the mounting cavity, a rotating shaft is provided at the front and rear ends of the wire drum mounting frame, and the wire drum mounting frame is rotatably mounted in the mounting cavity through the rotating shaft, and the rotation center line of the wire drum mounting frame coincides with the rotation center line of the tubular body. A wire pay-off drum is detachably mounted on the wire drum mounting frame, and the wire pay-off drum is rotatably mounted on the wire drum mounting frame, and the rotation center line of the wire pay-off drum is perpendicular to the rotation center line of the wire drum mounting frame. The rotating power source drives the tubular body to rotate, and the tubular body drives the synchronous rotation of each copper wire, thereby achieving the purpose of twisting the copper wires. For another example, the patent with announcement number CN218826395U discloses a high-speed tubular stranding machine, which drives the cylinder to rotate at high speed through a motor to achieve the purpose of stranding.

[0004] However, the tube cages of the two above-mentioned tube-type agitator machines are driven by motors to rotate at high speed, which will cause the wire reel frame connected to the tube cage to swing. Since the wire reel will rotate relative to the wire reel frame to release the single strand of wire on the wire reel, the swing of the wire reel frame will affect the uniformity of the wire reel payout, and thus affect the quality of the twisted wire. Summary of the invention

[0005] In view of this, the present invention provides a tubular stranding machine to solve the technical problem that the uniformity of the wire reel pay-off is affected by the swing of the wire reel frame caused by the high-speed rotation of the tube cage.

[0006] In order to solve the above technical problems, the present invention provides a tubular stranding machine, comprising a tube cage, a wire drum frame rotatably connected in the tube cage, a wire drum rotatably connected to the wire drum frame, and a driving assembly for driving the tube cage to rotate. The wire drum frame is provided with a counterweight mechanism, and the counterweight mechanism comprises a mounting shaft slidably connected to both sides of the wire drum frame and used to mount the wire drum, a connecting plate rotatably connected to the mounting shaft, and a counterweight assembly arranged on the connecting plate; the mounting shaft is rotatably connected to the wire drum frame and moves synchronously with the wire drum, and a sliding rod is fixedly connected to the end of the connecting plate;

[0007] The counterweight assembly includes a slide plate fixedly mounted on the reel frame, a connecting rod hinged at the end of the slide rod, a support rod fixedly connected to the connecting rod and located on one side of the reel, a counterweight sleeve sleeved between two support rods located on the same side of the reel and capable of contacting the edge of the reel, and a spring connected between the two support rods;

[0008] The sliding plate is perpendicular to the connecting plate and a sliding groove capable of allowing the sliding rod to pass through is obliquely provided on the sliding plate, and two sliding grooves located on the same side of the wire drum are close to each other from top to bottom.

[0009] By adopting the above technical scheme, when installing the wire drum, the wire drum is installed on the installation shafts on both sides of the wire drum frame. The installation and disassembly of the wire drum are convenient. The installation shaft and the wire drum rotate synchronously by friction. Under the action of the gravity of the wire drum, the installation shaft slides downward, and the connecting plate slides downward with the installation shaft. The connecting plate drives the sliding rod to move along the sliding groove, and the sliding rod drives the connecting rod and the support rod to move, so that the two support rods on the same side of the wire drum move downward and towards each other. The downward movement of the two support rods is conducive to driving the counterweight sleeve to the center. Since the edge of the wire drum is in contact with the counterweight sleeve, the counterweight sleeve is conducive to driving the wire drum to the center. The present invention can set the counterweight mechanism so that the center of gravity of the wire drum is biased downward, which is beneficial to reducing the swing of the wire drum frame, thereby improving the uniformity of wire drum pay-off, and further helping to improve the quality of twisted wire. After the wire drum is installed on the wire drum frame, the two support rods on the same side of the wire drum move downward and towards each other, which is beneficial to driving the counterweight sleeve to be centered, improving the stability of the counterweight, and further helping to reduce the swing of the wire drum frame. Since the edge of the wire drum is in contact with the counterweight sleeve, the counterweight sleeve can drive the wire drum to move during its movement, which is beneficial for the counterweight sleeve to drive the wire drum to be centered, thereby improving the uniformity of wire drum pay-off.

[0010] Preferably, a torsion spring is connected between the slide rod and the connecting rod, and a limit plate capable of limiting the connecting rod is fixedly provided on one side of the slide plate, so that the connecting rod is in a vertical state when the slide rod is located at the upper end of the slide groove, and is in an inclined state when the slide rod is located at the lower end of the slide groove.

[0011] By adopting the above technical solution, when installing the wire drum, during the process of the slide bar sliding down along the slide slot, the connecting rod is in a vertical state due to the limitation of the limit plate, which is conducive to the contact between the wire drum and the counterweight sleeve, and the counterweight sleeve drives the wire drum to the center position. When the slide bar slides to the bottom of the slide slot, the limit plate loses the limitation on the connecting rod, and the connecting rod tilts away from the axis of the wire drum under the action of the torsion spring, thereby driving the support rod and the counterweight sleeve to deflect, so that the counterweight sleeve does not contact the wire drum, which is conducive to the wire drum pay-off and improves the uniformity of the wire drum pay-off.

[0012] Preferably, a limiting rod capable of limiting the position of the connecting rod in an inclined state is fixedly installed below the limiting plate.

[0013] By adopting the above technical solution, the sliding rod slides to the bottom of the slide groove, the connecting rod tilts under the action of the torsion spring, and the limit rod limits the inclination state of the connecting rod, which is beneficial for the inclination angles of multiple connecting rods to be consistent. At the same time, it is also beneficial for the sliding rod to drive the connecting rod to rise along the slide groove, and the limit plate keeps the connecting rod in the initial vertical state.

[0014] Preferably, the wire drum comprises two disc wheels and a winding roller, the two disc wheels are fixedly mounted at two ends of the winding roller, and a plurality of threaded grooves for clamping the disc wheels are formed on the counterweight sleeve.

[0015] By adopting the above technical solution, a single strand of wire is wound on the winding roller, and the disc wheel contacts the counterweight sleeve and is clamped in the thread groove of the counterweight sleeve, which is conducive to the counterweight sleeve driving the wire disc to be centered.

[0016] Preferably, two counterweight assemblies are respectively provided on both sides of the installation shaft, and the two counterweight assemblies are symmetrically structured with the axis of the installation shaft as the axis of symmetry.

[0017] By adopting the above technical solution, counterweights are loaded on both sides of the wire drum, which is beneficial to increasing the weight of the counterweight and balancing the gravity on both sides of the wire drum, and is beneficial to improving the uniformity of wire drum pay-off.

[0018] Preferably, both sides of the wire drum rack are provided with card slots, sliders are slidably installed in the card slots, the installation shaft is rotatably connected to the sliders, and a reset spring is connected between the sliders and the card slots.

[0019] By adopting the above technical solution, when the wire drum is not installed on the installation shaft, under the action of the reset spring, the slider drives the installation shaft to move to the upper part of the slot. This is the initial state. After the wire drum is installed on the installation shaft, the gravity of the wire drum overcomes the elastic force of the reset spring, driving the installation shaft and the slider to move down along the slot, which is beneficial to improve the uniformity of the wire drum payout.

[0020] Preferably, the end of the mounting shaft is rotatably connected to a toothed disc, a friction transmission component is hinged on the toothed disc, a flexible friction plate in contact with the mounting shaft is fixedly mounted on one end of the friction transmission component, a compression spring is connected between the other end and the toothed disc, a flywheel is rotatably connected to the slider, and the flywheel and the toothed disc are connected by a gear transmission; when the mounting shaft rotates, the friction transmission component deflects to the side away from or close to the mounting shaft.

[0021] By adopting the above technical solution, when twisting the wire, the wire drum drives the installation shaft to rotate clockwise, the installation shaft drives the toothed disc to rotate through the friction transmission member, and the toothed disc drives the flywheel to rotate through the gear transmission connection. Since the friction transmission member is hinged on the toothed disc and a compression spring is connected between the friction transmission member and the toothed disc, the friction transmission member deflects to the side close to the installation shaft, thereby increasing the friction between the friction transmission member and the installation shaft, which is beneficial to improving the stability of the rotation of the installation shaft. Since the installation shaft rotates synchronously with the wire drum, it is beneficial to improve the stability of the wire drum release, and it is also beneficial to reduce the locking transmission, so that the single-strand wire on the wire drum can be protected. When the single-strand wire on the wire drum stops pulling, the flywheel continues to rotate due to inertia, and the flywheel drives the toothed disc to rotate through the gear transmission connection. Since the friction transmission member is hinged on the toothed disc, the friction transmission member deflects to the side away from the installation shaft, thereby reducing the friction between the friction transmission member and the installation shaft, reducing the occurrence of the installation shaft rotating synchronously with the toothed disc, and reducing the probability of the wire drum actively releasing the wire.

[0022] Preferably, the slider is rotatably connected to a rotating shaft, one end of the rotating shaft is rotatably connected to gear 1 meshing with the gear plate, the other end of the rotating shaft is fixedly mounted with gear 2, the flywheel is fixedly mounted with a gear ring meshing with gear 2, and the number of teeth on gear 1 is less than the number of teeth on the gear plate.

[0023] By adopting the above technical solution, the mounting shaft drives the toothed disc to rotate, and the toothed disc drives the first gear, the rotating shaft, the second gear and the gear ring to rotate in turn, thereby driving the flywheel to rotate.

[0024] The beneficial effects of the above technical solution of the present invention are as follows:

[0025] 1. When installing the wire drum according to the present invention, the wire drum is installed between two installation shafts, and the installation and disassembly of the wire drum is convenient. The wire drum and the installation shaft fall under the action of their own gravity. In addition, setting the counterweight mechanism can make the center of gravity of the wire drum biased downward, which is beneficial to reduce the swing of the wire drum frame, thereby improving the uniformity of wire drum pay-off, and further helping to improve the quality of twisted wire. After the wire drum is installed on the wire drum frame, the two support rods on the same side of the wire drum move downward and toward each other, which is beneficial to drive the counterweight sleeve to be centered, improves the stability of the counterweight, and further helps to reduce the swing of the wire drum frame. The counterweight sleeve can drive the wire drum to move during its movement, which is beneficial for the counterweight sleeve to drive the wire drum to be centered, improves the uniformity of wire drum pay-off, and further improves the quality of twisted wire.

[0026] 2. When the wire drum is installed in the present invention, during the process of the slide rod sliding downward along the slide slot, due to the limitation of the limit plate, the connecting rod is in a vertical state, which is conducive to the contact between the wire drum and the counterweight sleeve, and the counterweight sleeve drives the wire drum to be in a central position; when the slide rod slides to the bottom of the slide slot, the limit plate loses the limitation on the connecting rod, and the connecting rod tilts away from the axis of the wire drum under the action of the torsion spring, thereby driving the support rod and the counterweight sleeve to deflect, so that the counterweight sleeve does not contact the wire drum, which is conducive to the wire drum unwinding.

[0027] 3. When the present invention is twisting the wire, the wire drum drives the installation shaft to rotate clockwise, the installation shaft drives the toothed disk to rotate through the friction transmission part, and the toothed disk drives the flywheel to rotate through the gear transmission connection; since the friction transmission part is hinged on the toothed disk and a compression spring is connected between the toothed disk, the friction transmission part deflects to the side close to the installation shaft, thereby increasing the friction force between the friction transmission part and the installation shaft, which is beneficial to improving the stability of the rotation of the installation shaft, and since the installation shaft and the wire drum rotate synchronously, it is beneficial to improve the stability of wire drum wire release, and at the same time it is beneficial to reduce the locking transmission, so that the single wire on the wire drum can be protected; when the single wire on the wire drum stops pulling, the flywheel continues to rotate due to inertia, and the flywheel drives the toothed disk to rotate through the gear transmission connection, and since the friction transmission part is hinged on the toothed disk, the friction transmission part deflects to the side away from the installation shaft, thereby reducing the friction force between the friction transmission part and the installation shaft, reducing the occurrence of the situation where the installation shaft rotates synchronously with the toothed disk, and reducing the probability of the wire drum actively releasing the wire.

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 8 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0038] Example

[0039] This embodiment provides a tubular stranding machine, such as Figure 1 As shown, it includes a pipe cage 1, a wire drum rack 2, a wire drum 3 and a driving assembly 4.

[0040] like Figure 1 and Figure 4 As shown, the wire drum frame 2 is rotatably connected in the tube cage 1 and multiple wire drums are arranged along the axial direction of the tube cage 1. The wire drum 3 is rotatably connected in the wire drum frame 2, and the wire drum 3 includes two disc wheels 31 and a winding roller 32. The two disc wheels 31 are fixedly mounted at both ends of the winding roller 32, and the winding roller 32 is used to wind the single strand wire.

[0041] like Figure 1 As shown, the driving assembly 4 is installed at one end of the tube cage 1, and is used to drive the tube cage 1 to rotate. The single strand wire on the winding tube passes through the tube cage 1, and the wire is twisted as the tube cage 1 rotates.

[0042] like Figure 2 As shown, a counterweight mechanism 5 is provided on the wire drum rack 2.

[0043] like Figure 1 As shown, the counterweight mechanism 5 includes a mounting shaft 51 , a connecting plate 52 and a counterweight assembly 53 .

[0044] like Figure 3As shown, a slot 21 is provided on both sides of the wire drum rack 2, and a slider 54 is slidably installed in the slot 21. The slider 54 can slide up and down in the slot 21. The installation shaft 51 is rotatably connected to the slider 54, and a return spring is connected between the slider 54 and the slot 21.

[0045] like Figure 1 As shown, the two mounting shafts 51 are symmetrically arranged, and the end surfaces of the two mounting shafts 51 facing each other are both provided with chamfers to facilitate the installation of the wire drum 3. The two ends of the wire drum 3 are respectively installed on the two mounting shafts 51. When the wire drum 3 is not installed on the two mounting shafts 51, under the elastic force of the reset spring, the slider 54 drives the mounting shaft 51 to be located at the upper part of the card slot 21, and the axes of the two mounting shafts 51 are collinear. After the wire drum 3 is installed on the mounting shaft 51, under the gravity of the wire drum 3, the slider 54 and the mounting shaft 51 move downward along the card slot 21 to the lower part of the card slot 21, and the mounting shaft 51 and the wire drum 3 rotate synchronously by friction, and the mounting shaft 51 and the wire drum 3 can also be connected by a key to achieve synchronous rotation.

[0046] like Figure 2 and Figure 3 As shown, the connecting plate 52 is rotatably connected to the mounting shaft 51, and the axis of the mounting shaft 51 is perpendicular to the plate surface of the connecting plate 52. Both ends of the connecting plate 52 are fixedly connected with sliding rods 521.

[0047] like Figure 2 and Figure 3 As shown, the counterweight assembly 53 includes a slide plate 531 , a connecting rod 532 , a supporting rod 533 and a counterweight sleeve 534 .

[0048] like Figure 2 and Figure 3 As shown, two counterweight assemblies 53 are respectively arranged on both sides of the installation shaft 51 , and the two counterweight assemblies 53 are symmetrically structured with the axis of the installation shaft 51 as the symmetry axis.

[0049] like Figure 2 and Figure 3 As shown, the plate surface of the slide plate 531 is perpendicular to the plate surface of the connecting plate 52, that is, the plate surface of the slide plate 531 is parallel to the axis of the mounting shaft 51. The two slide plates 531 are fixedly mounted on the bobbin frame 2 and are located on both sides of the mounting shaft 51. The slide plates 531 are obliquely provided with a slide groove 537, and the two slide grooves 537 located on the same side of the bobbin 3 are close to each other from top to bottom.

[0050] like Figure 2 and Figure 3 As shown, the slide rod 521 passes through the slide groove 537 and can slide along the slide groove 537 , the connecting rod 532 is hinged at the end of the slide rod 521 after passing through the slide groove 537 , and a torsion spring 535 is also connected between the connecting rod 532 and the slide rod 521 .

[0051] like Figure 2 and Figure 6 As shown, the support rod 533 is vertically connected to the end of the connecting rod 532, and the support rod 533 is parallel to the axis of the mounting shaft 51. A spring 538 is connected between the two support rods 533 located on the same side of the wire drum 3, and a weight sleeve 534 capable of contacting the disk wheel 31 of the wire drum 3 is sleeved on the two support rods 533. The weight sleeve 534 is provided with a plurality of threaded grooves 536 for clamping the disk wheel 31.

[0052] like Figure 2 and Figure 3 As shown, a limiting plate 55 capable of limiting the position of the connecting rod 532 is fixedly provided on one side of the slide plate 531, and the limiting plate 55 is parallel to the slide plate 531. When the slide bar 521 is located at the upper end of the slide slot 537, the connecting rod 532 is in a vertical state due to the limiting of the limiting plate 55; when the slide bar 521 is located at the lower end of the slide slot 537, the limiting plate 55 loses the limiting of the connecting rod 532, and the connecting rod 532 is in an inclined state under the action of the torsion spring 535. A limiting rod 56 capable of limiting the connecting rod 532 in an inclined state is fixedly installed below the limiting plate 55.

[0053] like Figure 1 and Figure 3 As shown, when installing the wire drum 3, the wire drum 3 can be installed on the installation shafts 51 on both sides of the wire drum frame 2 by hoisting, which is convenient for installation and removal of the wire drum 3. The installation shaft 51 and the wire drum 3 rotate synchronously by friction. Under the action of the gravity of the wire drum 3, the slider 54 slides downward along the card slot 21, thereby driving the installation shaft 51 to slide downward, and the connecting plate 52 slides downward along the installation shaft 51. The connecting plate 52 drives the sliding rod 521 to move along the sliding groove 537, and the sliding rod 521 drives the connecting rod 532 and the supporting rod 533 to move, so that the two supporting rods 533 on the same side of the wire drum 3 move downward and towards each other. The downward movement of the two supporting rods 533 is conducive to driving the counterweight sleeve 534 to the center, as shown in FIG. Figure 2 As shown, due to the limitation of the limiting plate 55, the connecting rod 532 is in a vertical state, and the wheel 31 of the wire drum 3 is clamped in the threaded groove 536 of the counterweight sleeve 534, which is conducive to the counterweight sleeve 534 driving the wire drum 3 to be centered. The wire drum 3 and the installation shaft 51 fall under the action of their own gravity, and the setting of the counterweight mechanism 5 so that the center of gravity of the wire drum 3 is biased downward is conducive to reducing the swing of the wire drum frame 2, thereby improving the uniformity of the wire drum 3 unwinding, and further helping to improve the quality of the stranded wire. When the slide bar 521 slides to the bottom of the slide groove 537, as shown in FIG. Figure 3As shown, the limiting plate 55 loses the limiting position on the connecting rod 532, and the connecting rod 532 is tilted away from the axis of the wire drum 3 under the action of the torsion spring 535, thereby driving the support rod 533 and the counterweight sleeve 534 to deflect, so that the counterweight sleeve 534 does not contact the wire drum 3, which is conducive to the wire drum 3 to release the wire and improve the uniformity of the wire drum 3. At the same time, the limiting rod 56 limits the tilting state of the connecting rod 532, which is conducive to the consistent tilt angle of multiple connecting rods 532, and also helps the limiting plate 55 to keep the connecting rod 532 in the initial vertical state when the sliding rod 521 drives the connecting rod 532 to rise along the sliding groove 537.

[0054] like Figure 7 and Figure 8 As shown, the end of the installation shaft 51 is rotatably connected with a toothed disc 6, an annular groove 61 is provided in the toothed disc 6, and a plurality of friction transmission members 62 are hinged in the annular groove 61. The friction transmission member 62 is a bending member, having a bending portion 1 621 and a bending portion 2 622. The angle between the bending portion 1 621 and the bending portion 2 622 is an obtuse angle. A hinge shaft is connected between the bending portion 1 621 and the annular groove 61, and a flexible friction sheet 623 in contact with the installation shaft 51 is fixedly installed on the bending portion 2 622. A compression spring 624 is connected between the end of the bending portion 2 622 away from the flexible friction sheet 623 and the side wall of the annular groove 61.

[0055] like Figure 4 and Figure 5 As shown, a rotating shaft 63 is rotatably connected to the slider 54, and the axis of the rotating shaft 63 is parallel to the axis of the mounting shaft 51. One end of the rotating shaft 63 is rotatably connected to a gear 1 64 meshing with the outside of the gear plate 6, and the other end of the rotating shaft 63 is fixedly installed with a gear 2 65. A flywheel 66 is rotatably connected to the slider 54, and a gear ring 67 meshing with the outside of the gear 2 65 is fixedly installed on the flywheel 66. The number of teeth on the gear 1 64 is less than the number of teeth on the gear plate, which is conducive to accelerating the rotation speed of the rotating shaft 63, thereby accelerating the rotation of the flywheel 66.

[0056] like Figure 4 and Figure 5 As shown, when twisting the wire, the wire drum 3 drives the installation shaft 51 to rotate clockwise, and the installation shaft 51 drives the toothed disc 6 to rotate through the friction transmission member 62, and the toothed disc 6 sequentially drives the gear 1 64, the rotating shaft 63, the gear 2 65 and the gear ring 67 to rotate, and then drives the flywheel 66 to rotate. Figure 8As shown, since the friction transmission member 62 is hinged on the toothed disc 6 and a compression spring 624 is connected to the toothed disc 6, the friction transmission member 62 deflects to the side close to the mounting shaft 51, that is, deflects counterclockwise along the hinge axis, thereby increasing the friction force between the mounting shaft 51 and the mounting shaft 51, which is beneficial to improving the rotation stability of the mounting shaft 51. Since the mounting shaft 51 rotates synchronously with the wire drum 3, it is beneficial to improve the stability of the wire drum 3 in unwinding, and at the same time it is beneficial to reduce the locking transmission, so that the single strand of wire on the wire drum 3 can be protected. When the single-strand line on the reel 3 stops being pulled, the flywheel 66 continues to rotate due to inertia, and the flywheel 66 drives the ring gear 67, gear 2 65, shaft 63, gear 1 64 to rotate in turn, and then drives the toothed disc 6 to rotate. Since the friction transmission member 62 is hinged on the toothed disc 6, the friction transmission member 62 deflects to the side away from the installation shaft 51, that is, it deflects clockwise along the hinge axis, thereby reducing the friction between the installation shaft 51, reducing the occurrence of the installation shaft 51 rotating synchronously with the toothed disc 6, and reducing the probability of the reel 3 actively releasing the line.

[0057] A method for using a tubular stranding machine comprises the following steps:

[0058] Step 1: Install the wire drum 3 on the installation shafts 51 on both sides of the wire drum frame 2. Under the action of the gravity of the wire drum 3, the slider 54 slides downward along the card slot 21, thereby driving the installation shaft 51 to slide downward, and the connecting plate 52 slides downward along the installation shaft 51. The connecting plate 52 drives the sliding rod 521 to move along the sliding slot 537. The sliding rod 521 drives the connecting rod 532 and the supporting rod 533 to move, so that the two supporting rods 533 on the same side of the wire drum 3 move downward and towards each other. The downward movement of the two supporting rods 533 is conducive to driving the counterweight sleeve 534 to the center. The limiting plate 55 limits the position of the connecting rod 532 in a vertical state. Since the disk wheel 31 of the wire drum 3 is clamped in the threaded groove 536 of the counterweight sleeve 534, it is conducive to the counterweight. The weight sleeve 534 drives the wire drum 3 to be centered, and when the sliding rod 521 slides to the bottom of the sliding groove 537, the limiting plate 55 loses the limiting position on the connecting rod 532, and the connecting rod 532 is tilted in the direction away from the axis of the wire drum 3 under the action of the torsion spring 535, thereby driving the support rod 533 and the counterweight sleeve 534 to deflect, so that the counterweight sleeve 534 is not in contact with the wire drum 3, which is beneficial to the wire drum 3 to release the wire and improve the uniformity of the wire drum 3 to release the wire; at the same time, the limiting rod 56 limits the inclined state of the connecting rod 532, which is beneficial to the consistent inclination angles of multiple connecting rods 532, and also beneficial to the limiting plate 55 to keep the connecting rod 532 in the initial vertical state when the sliding rod 521 drives the connecting rod 532 to rise along the sliding groove 537;

[0059] Step 2: Pass the single strand of wire on the wire reel 3 through the tube cage 1, start the drive assembly 4, and achieve wire twisting;

[0060] Step 3: The wire drum 3 releases the wire in a clockwise direction, driving the installation shaft 51 to rotate clockwise. The installation shaft 51 drives the toothed disc 6 to rotate through the friction transmission member 62. The toothed disc 6 drives the gear 1 64, the rotating shaft 63, the gear 2 65 and the gear ring 67 to rotate in turn, thereby driving the flywheel 66 to rotate. The friction transmission member 62 deflects toward the side close to the installation shaft 51, that is, deflects counterclockwise along the hinge axis, thereby increasing the friction force between the installation shaft 51 and the installation shaft 51, which is beneficial to reducing the locking transmission, thereby protecting the single strand of wire on the wire drum 3.

[0061] Step 4: After the stranding is completed, the drive assembly 4 is closed. When the single strand of wire on the wire drum 3 stops being pulled, the flywheel 66 continues to rotate due to inertia, and the flywheel 66 drives the gear ring 67, the second gear 65, the rotating shaft 63, and the first gear 64 to rotate in sequence, thereby driving the toothed disc 6 to rotate. Since the friction transmission member 62 is hinged on the toothed disc 6, the friction transmission member 62 deflects to the side away from the installation shaft 51, that is, it deflects clockwise along the hinge axis, thereby reducing the friction between the installation shaft 51 and the installation shaft 51, reducing the occurrence of the synchronous rotation of the installation shaft 51 following the toothed disc 6, and reducing the probability of the wire drum 3 actively releasing the wire;

[0062] Step 5: When replacing the wire reel 3, remove the wire reel 3. Under the elastic force of the reset spring, the slider 54 drives the installation shaft 51 to rise to the upper part of the slot 21. The installation shaft 51 drives the connecting plate 52 and the slide rod 521 to rise. Due to the limiting effect of the limiting plate 55, the connecting rod 532 is in a vertical state. Then install the next wire reel 3 for twisting the wire.
