Description

Technical Field

[0001] The invention relates to the field of conductive core twisting for cable production, and more specifically to a conductive core twisting device for cable production and a use method thereof. Background Art

[0002] During the production and processing of cables, it is usually necessary to twist several cables together according to a certain structure to form a compact and uniform conductive core wire. At the same time, in order to reduce the gaps between the cables after twisting and improve the material and mechanical properties of the cables, several filling ropes are usually twisted together with the cables, and the surface of the twisted cables is wrapped with a tape material. The tape material can protect the internal structure of the cable and help to increase the service life of the cable.

[0003] However, in the process of twisting cables and filling ropes by existing twisting equipment, stress is easily generated inside the twisted cables, and these stresses are easy to cause cable shaking during the release process. At the same time, when the equipment is transporting the cable, the uneven friction between the equipment and the cable is also easy to cause the cable shaking. In the process of wrapping the shaking cable by the wrapping equipment, the wrapping effect of the equipment on the cable is easily reduced. Therefore, there is an urgent need to design a conductive core twisting device for cable production and a method of using it to solve the above problems.

[0022] A method for using a conductive core twisting device for cable production comprises the following steps:

[0023] S1: The operator first places the cable and the filling rope on the pay-off device in sequence, and stretches one end of the cable and the filling rope into the twisting device, and then uses the twisting device to complete the twisting of the cable and the filling rope;

[0024] S2: When the twisted cable is forced to move to the left side of the box, the spacing between the adjacent elastic plates and the rollers is adjusted by using the adjustment component according to the diameter of the cable, and then the driving component and the rolling component are used to control the rotation of the rolling plate and the elastic plate to roll and adjust the roundness of the cable surface.

[0027] S5: If the cable shakes violently during wrapping, the limit assembly and multiple sealing plates can be used to increase the impact force of blowing air on the cable surface, which can offset the inertia force of the cable shaking to a certain extent, thereby gradually stabilizing the cable. This can help further ensure the cable wrapping effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) This solution can achieve rolling adjustment of the surface shape of the twisted cable through the cooperation of the driving component and the rolling component, which can help improve the roundness of the cable surface and improve the effect of subsequent equipment on the cable surface wrapping. At the same time, through the knocking component, the intermittent knocking and vibration of the cable surface can accelerate the release of its internal stress, which can effectively reduce the subsequent cable jitter caused by the release of internal stress during the wrapping process, which helps to improve the equipment's cable wrapping effect;

[0030] (2) This solution uses the positioning component to achieve non-contact clamping and positioning of the cable using airflow, which can not only effectively reduce the mechanical wear caused by the equipment's contact with the cable during the cable transportation process, but also effectively improve the stability of the cable position during the subsequent cable wrapping process of the equipment, which helps to further improve the cable wrapping processing effect of the equipment;

[0031] (3) If the cable shakes violently during the cable wrapping process, the limit component and the positioning component can cooperate to increase the impact force of blowing air on the cable surface, which can offset the inertia force of the cable shaking to a certain extent, thereby causing the cable to gradually stabilize. This can help to further ensure the stability of the cable during the wrapping process and help to further improve the cable wrapping effect of the equipment.

[0057] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0058] See also Figures 1 to 17 A conductive core twisting device for cable production includes a support frame 1 and a cable 10. A box 2 is fixedly installed on the support frame 1, a driving component 5 is arranged in the box 2, a rolling component 6 is arranged in the box 2, a positioning component 8 is arranged on the box 2, and a limiting component 9 is arranged in the box 2.

[0059] like Figure 1 As shown, a pay-off device 11 is installed on the support frame 1, a twisting device 12 is fixedly installed on the support frame 1, a taping device 13 is installed on the box body 2, a conveying device 14 is fixedly installed on the support frame 1, and a winding device 15 is installed on the support frame 1.

[0060] When a device individually twists several cables, gaps are likely to exist between the cables. Therefore, in order to reduce the gaps between the twisted cables and improve the physical properties and service life of the twisted cable 10, the cables are usually twisted together with filler ropes.

[0061] When the device is required to be used to twist the cable 10, the operator needs to first place the rolled cables and the filling rope on the unwinding device 11 in sequence, and stretch one end of each of the cables into the twisting device 12. Then, the twisting device 12 is operated to twist the cables and the filling rope together. At the same time, during the twisting process of the cables and the filling rope, the twisting device 12 applies a thrust to the right side to the twisted cable 10 (such as Figure 1 In the initial stage, after the cable 10 obtained by stranding is forced to move out of the stranding device 12, the cable 10 needs to be continuously pulled to the right (such as Figure 1 direction shown);

[0062] When the cable 10 is forced to move to the lower end of the tape wrapping device 13, the tape wrapping device 13 continues to operate, so that the tape material can be wrapped around the surface of the cable 10. The tape wrapped around the surface of the cable 10 can help to enhance the mechanical properties of the cable 10 and protect the internal structure of the cable 10. After the cable 10 is wrapped, the right end of the cable 10 moves to the top of the winding device 15. At this time, the winding device 15 and the conveying device 14 cooperate to operate, so that the remaining twisted cable 10 can be pulled and wound (that is, the operation of the existing guide wheel and traction equipment can be stopped at this time).

[0063] Among them, the working principles and components of the pay-off device 11, the twisting device 12, the taping device 13, the conveying device 14, and the winding device 15 are all existing mature technologies and will not be further elaborated here.

[0064] like Figure 1 - Figure 6 As shown, the driving assembly 5 includes a fixed disk 510 rotatably mounted in the housing 2 , and a ring-shaped uniformly distributed rotating shaft 58 is penetrated and rotatably mounted on the fixed disk 510 , and a driving mechanism is installed between the rotating shaft 58 and the housing 2 .

[0065] The driving mechanism includes a support plate 51 fixedly mounted on the box body 2, a servo motor 52 fixedly mounted on the support plate 51, a gear rack 1 53 fixedly mounted on the driving end of the servo motor 52, an annular slide groove 3 is provided in the box body 2, a gear rack 2 54 meshing with the gear rack 1 53 is rotatably mounted on the annular slide groove 3, and connecting rods 55 evenly distributed in an annular shape are fixedly mounted on the gear rack 2 54;

[0066] A rotating gear 56 is fixedly installed between the connecting rods 55 , an internal gear ring 57 is fixedly installed in the box body 2 , and spur gears 59 meshing with the rotating gear 56 are fixedly installed on the rotating shafts 58 , and the spur gears 59 mesh with the internal gear ring 57 .

[0067] When the cable 10 is forced to move to the left end of the box 2 (such as Figure 2 The servo motor 52 is started, and the operation of the servo motor 52 drives the rotating gear 56 to rotate through the cooperation of the gear frame 1 53, the gear frame 2 54, and multiple connecting rods 55. During the rotation of the rotating gear 56, it can cooperate with the internal gear ring 57 and multiple spur gears 59 to drive multiple rotating shafts 58 to rotate while rotating on its own.

[0068] like Figure 1 - Fig.10 As shown, the rolling assembly 6 includes limit plates 68 respectively fixedly mounted on the rotating shaft 58, and a rolling component is commonly installed between the limit plates 68. Discs 61 are rotatably mounted on the rotating shaft 58, and a knocking component is commonly installed between the discs 61.

[0069] The rolling parts include grooves 610 that are evenly arranged on the limiting plates 68 in an annular shape, and spring telescopic rods 64 are slidably installed on the grooves 610. Adjustment plates 69 are fixedly installed on the rotating shafts 58. The adjustment plates 69 are provided with sliding openings 611 evenly distributed in an annular shape, and sliders 612 are slidably installed on the sliding openings 611, and the sliders 612 are fixedly connected to the corresponding spring telescopic rods 64.

[0070] The spring telescopic rod 64 is fixedly mounted with a rolling plate 65, the outer wall of the rolling plate 65 is fixedly mounted with an elastic plate 66, and the inner wall of the rolling plate 65 is fixedly mounted with an inclined block 67 (the inner and outer sides here refer to Figure 8 , Figure 8 The elastic plate 66 in the figure is located at the outer side, and the spring telescopic rod 64 in the figure is located at the inner side).

[0071] In the initial state, the spacing between the three adjacent elastic plates 66 is slightly larger than the diameter of the cable 10. The purpose is that when the cable 10 is forced to move to the middle position of the three adjacent elastic plates 66, the multiple rotating shafts 58 are driven by the driving assembly 5 to rotate and rotate. The multiple rotating shafts 58 cooperate with the corresponding limit plates 68, the adjustment plates 69, and the multiple spring telescopic rods 64 to drive the multiple rolling plates 65 to cooperate with the multiple elastic plates 66 to roll on the surface of the cable 10;

[0072] During the rolling process of the cable 10, multiple rolling plates 65 and multiple elastic plates 66 cooperate to apply a uniform extrusion force to the surface of the cable 10, and the extrusion force helps to improve the overall roundness of the cable 10, and helps to improve the effect of the subsequent wrapping equipment 13 on the cable 10 (i.e., the effect of wrapping the wrapping material).

[0073] If the cable 10 obtained by twisting the equipment has a low degree of roundness (the equipment is suitable for twisting cables 10 with a circular cross-section), it is easy to reduce the uniformity of the overall fit between the tape material and the surface of the cable 10 during the subsequent tape wrapping process of the cable 10 by the tape wrapping equipment 13, and it is easy to reduce the tightness of the fit between the tape material and the surface of the cable 10, which is easy to cause the tape material wrapped on the surface of the cable 10 to become loose, deviate, etc., thereby reducing its protective effect on the cable 10, that is, reducing the subsequent performance of the cable 10. Therefore, before the cable 10 is taped, the rolling adjustment of the surface shape of the cable 10 by multiple rolling plates 65 and elastic plates 66 can help improve the roundness of the surface of the cable 10, improve the uniformity of the overall wrapping of the cable 10 by the subsequent tape wrapping equipment 13, and improve the effect of the wrapping process.

[0074] At the same time, the purpose of arranging elastic plates 66 on the outside of the rolling plates 65 (the elastic plates 66 can be made of elastic materials such as polyurethane rubber) is that when the multiple rolling plates 65 are subjected to force to drive the corresponding elastic plates 66 to roll on the cable 10, the elasticity of the elastic plates 66 can not only effectively improve the fit between the elastic plates 66 and the surface of the cable 10, that is, the effect of rolling and adjusting the surface shape of the cable 10, but also effectively reduce the wear of the equipment on the surface of the cable 10 during the process of rolling the surface of the cable 10, which helps to improve the production quality of the cable 10.

[0075] At the same time, multiple rolling plates 65 are arranged through corresponding elastic plates 66. During the rolling process of the surface of the cable 10, the reaction force exerted by the cable 10 on the corresponding rolling plate 65 through the elastic plate 66 is smaller than the elastic force of the corresponding spring telescopic rod 2 64. The purpose is to ensure the effect of rolling and adjusting the surface shape of the cable 10 by the multiple rotating shafts 58 through the multiple spring telescopic rods 2 64 in cooperation with the rolling plates 65 and the elastic plates 66.

[0076] like Figure 2 - Figure 8 As shown, the striking component includes spring telescopic rods 62 respectively fixedly mounted on the disc 61, and a striking wheel 63 is fixedly mounted on the spring telescopic rods 62.

[0077] When the multiple rotating shafts 58 are subjected to force to rotate around the surface of the cable 10 and rotate on their own, the corresponding spring telescopic rods 62 and the knocking wheels 63 are driven to rotate through the corresponding disks 61. However, since the multiple disks 61 and the corresponding rotating shafts 58 are rotationally connected, the multiple knocking wheels 63 are always opposite to the surface of the cable 10 during the process of being subjected to force to rotate.

[0078] When the plurality of rotating shafts 58 drive the plurality of rolling plates 65 to cooperate with the plurality of elastic plates 66 to roll and adjust the surface shape of the cable 10, the rolling plates 65 will drive the corresponding inclined blocks 67 to intermittently move toward the right end of the corresponding knocking wheel 63 (such as Figure 8 As shown in the direction, when the inclined block 67 gradually moves toward the lower end of the knocking wheel 63, the knocking wheel 63 will continuously move to the left along the inclination of the corresponding inclined block 67 surface, and continuously compress its corresponding spring telescopic rod 1 62. When the inclined block 67 is forced to move away from the knocking wheel 63, the spring telescopic rod 1 62 will drive the knocking wheel 63 to quickly return to the right side under the elastic force of the spring telescopic rod 1 62, and knock the inner wall of the corresponding rolling plate 65. The vibration force generated by the knocking of the rolling plate 65 will be transmitted to the cable 10 through the corresponding elastic plate 66, so as to achieve the effect of knocking and vibrating the surface of the cable 10.

[0079] By continuing the above operation, the surface of the cable 10 can be intermittently tapped and vibrated, which can help speed up the release of internal stress of the cable 10 and reduce the possibility of vibration of the cable 10 due to its own internal stress during the subsequent wrapping process of the cable 10 by the wrapping equipment 13, thereby affecting the final wrapping effect of the cable 10 surface.

[0080] During the twisting process of the cable and the filling rope, the cable and the filling rope will be bent, twisted, etc., and the cable filling rope itself has a certain elasticity. When it is bent or twisted, it is easy to generate elastic stress inside it. At the same time, when the cable and the filling rope are twisted and in close contact, the two are squeezed against each other, which is also easy to generate stress inside it, and these stresses are easy to be unevenly distributed inside the cable 10;

[0081] When the twisted cable 10 continues to move to the right (such as Figure 2In the direction shown), during the gradual release of its internal stress, the elastic restoring force inside the cable 10, especially the cable itself, easily causes the cable 10 to produce a slight deformation, and this deformation is difficult to have regularity. If the cable 10 is locally deformed significantly, it is easy to cause the cable 10 to shake, and the wrapping operation of the cable 10 by the wrapping device 13 is rhythmic. When the cable 10 continues to shake, it is easy to disrupt the rhythm, reducing the final wrapping effect of the cable 10, and the shaking cable 10 intermittently contacts the wrapping material, causing collision and friction, which is easy to further aggravate the shaking of the cable 10, further reducing the wrapping effect of the cable 10, that is, reducing the subsequent performance of the cable 10;

[0082] Therefore, before the surface of the cable 10 is taped, the release of the internal stress of the cable 10 is accelerated, so that the vibration of the cable 10 caused by the release of internal stress during the subsequent taping equipment 13 wrapping the cable 10 can be effectively reduced, thereby reducing the wrapping effect. In addition, by cooperating with multiple knocking wheels 63 that are continuously rotated around the surface of the cable 10 under force, the uniformity of the equipment's knocking vibration on the surface of the cable 10 can be effectively improved, which helps to improve the uniformity of the release of internal stress of the cable 10, thereby helping to improve the effect of the subsequent wrapping of the cable 10 by the equipment.

[0083] At the same time, a plurality of knocking wheels 63 are provided with a specific detachable connection mode between the corresponding spring telescopic rods 62, such as a threaded connection, etc., in order to facilitate the user to select the weight of the knocking wheel 63 according to the material properties of the cable 10 (the strength of the internal stress of the cable 10 is related to the elasticity and hardness of the cable and the filling rope itself), thereby helping to improve the wide applicability of the device.

[0084] The knocking vibration force generated by the knocking wheel 63 on the cable 10 through the corresponding rolling plate 65 and the elastic plate 66 should be controlled within an appropriate range. The purpose is to avoid the knocking wheel 63 generating a large knocking vibration force on the surface of the cable 10, which will aggravate the shaking of the cable 10 and cause the surface of the cable 10 to deform due to knocking.

[0085] like Figure 7 - Fig.12 As shown, the box body 2 is provided with an adjustment assembly 7, which includes a limit opening 71 opened on the box body 2, a push block 72 is slidably mounted on the limit opening 71, a rod body 73 is fixedly mounted on the push block 72, and a limit chuck 74 is fixedly mounted on the rod body 73;

[0086] A push plate 75 is slidably mounted on the rotating shaft 58, and the push plate 75 is rotatably mounted on the limit chuck 74. The push plate 75 is fixedly mounted with positioning blocks evenly distributed in a ring shape, and a connecting plate 76 is rotatably mounted between the positioning block and the corresponding slider 612. A push component is installed on the push block 72.

[0087] The pushing component includes a second rod body 77 fixedly mounted on the pushing block 72 , an annular plate 78 fixedly mounted on the second rod body 77 , and limiting frames 79 evenly distributed in an annular shape fixedly mounted on the annular plate 78 .

[0088] When the cable 10 is forced to move to the right end of the box 2 (such as Fig.11 As shown in the direction), the spacing between the three adjacent elastic plates 66 can be adjusted according to the diameter of the cable 10. For example, when the push block 72 is manually pushed to move to the left (such as Fig.12 In the direction shown in FIG. 1 ), at this time, the rod body 73 and the limit chuck 74 apply a thrust to the left side to the plurality of push plates 75, so that the plurality of push plates 75 are forced to move upward (such as Fig.10 In the direction shown), during the upward movement of the push plate 75, the corresponding multiple spring telescopic rods 64 can be driven to drive the corresponding rolling plates 65 and elastic plates 66 to gradually expand through the cooperation of the corresponding multiple positioning blocks, the connecting plates 76, and the sliders 612, thereby helping to reduce the distance between the three adjacent elastic plates 66.

[0089] On the contrary, if the diameter of the cable 10 is large, the push block 72 is manually pushed to move to the right (such as Fig.12 In the direction shown), the spacing between the three elastic plates 66 can be gradually increased, so that the equipment can roll and knock and vibrate cables 10 of different sizes, which helps to further improve the application range of the equipment and facilitate the promotion and use of the equipment.

[0090] At the same time, when the corresponding multiple spring telescopic rods 2 64 are forced to expand or contract with each other, the corresponding adjustment disk 69, the slider 612 and the limit disk 68 cooperate to limit their movement, which helps to improve the stability of the corresponding spring telescopic rods 2 64 when they are forced to move.

[0091] like Fig.13 , Fig.14 As shown, the positioning assembly 8 includes an air collecting ring 82 fixedly installed in the box body 2, the air collecting ring 82 is provided with a cavity 85 which is evenly distributed in a ring shape, the air collecting ring 82 is fixedly connected with an arc tube 86 which is evenly distributed in a ring shape, the arc tube 86 is fixedly connected with an air injection pipe 87 which is evenly distributed in an arc shape, an air supply component is installed on the air collecting ring 82, and a sealing plate 810 is sealed and slidably installed on the cavity 85.

[0092] The air supply component includes an exhaust fan 81 fixedly mounted on the box body 2, the exhaust fan 81 is fixedly connected to an air supply pipe 83, the air supply pipe 83 is fixedly connected to an air injection pipe 84 evenly distributed in a ring shape, and one end of the air injection pipe 84 is sealed and passes through the air collecting ring 82 and extends into the corresponding cavity 85.

[0093] When the cable 10 is forced to move to the inside of the box 2, the exhaust fan 81 is started. The operation of the exhaust fan 81 can suck the gas outside the box 2 into the inside thereof, and input it into the cavity 85 respectively through the cooperation of the air delivery pipe 83 and the multiple air injection pipes 84 (the same amount of gas enters the multiple cavities 85 at the same time), and the gas entering the cavity 85 will eventually enter the corresponding arc pipe 86 and be ejected by the corresponding multiple air injection pipes 87;

[0094] Since the plurality of arc tubes 86 are evenly distributed around the cable 10 (from Fig.14 ), and in the initial state, the amount of gas entering the multiple arc tubes 86 and the gas flow rate are approximately the same, that is, the amount of gas and the flow rate of gas ejected from the multiple air jets 87 are approximately the same. Therefore, at this time, the airflow ejected from the multiple air jets 87 can achieve non-contact clamping and positioning of the cable 10, thereby further reducing the shaking of the cable 10 during the subsequent wrapping process of the cable 10 by the wrapping equipment 13.

[0095] When the cable 10 is forced to move downwards towards the taping device 13, it is easy to generate uneven friction due to contact with the device. When the friction changes periodically, it is easy to cause the cable 10 to shake. In addition, the taping device 13 runs for a long time, and its internal mechanical wear is easy to cause equipment vibration, that is, it is easy to cause the taping device 13 to shake during the wrapping process of the cable 10, thereby reducing the final taping effect of the cable 10 and the subsequent performance of the cable 10. Therefore, by adopting non-contact clamping and positioning of the cable 10 by airflow, it can not only effectively reduce the mechanical wear of the equipment when it contacts the cable 10 during the process of transporting the cable 10, but also effectively improve the stability of the position of the cable 10 during the wrapping process of the cable 10, which helps to further improve the wrapping effect of the cable 10 by the equipment.

[0096] At the same time, the operating power of the exhaust fan 81, that is, the amount of gas and the gas flow rate blown by the multiple air nozzles 87 to the surface of the cable 10, can be selected according to factors such as the size of the cable 10 and the hardness of the material.

[0097] like Fig.11 - Fig.16 As shown, the limit assembly 9 includes a limit groove 4 which is evenly arranged in a ring shape on the box body 2, and a fixing part 91 is slidably installed on the limit groove 4. A limit rod 92 which cooperates with the corresponding limit frame 79 is penetrated and fixedly installed on the fixing part 91, and a spring positioning part 93 is fixedly installed on the fixing part 91, and a roller 94 is fixedly installed on the spring positioning part 93. A plate body 88 is fixedly installed on the spring positioning part 93, and a sealing plate 89 which cooperates with the corresponding cavity 85 is fixedly installed on the plate body 88, and the sealing plate 89 is fixedly connected to the corresponding sealing plate 810.

[0098] When the cable 10 is forced to move to the right end of the box 2 (such as Fig.11 In the direction shown), at this time, through the cooperation of multiple rollers 94, the movement of the cable 10 can be further limited, so as to further improve the stability of the cable 10 when the equipment is wrapping the cable 10, that is, further improve the wrapping effect of the equipment on the cable 10.

[0099] At the same time, the surfaces of multiple rollers 94 are all made of elastic material in order to reduce the wear of the rollers 94 on the surface of the cable 10 when the rollers 94 contact the surface of the cable 10, thereby further ensuring the final production quality of the cable 10.

[0100] The spacing between the plurality of rollers 94 is always the same as the spacing between the three adjacent elastic plates 66. That is, when the spacing between the three adjacent elastic plates 66 is adjusted according to the diameter of the cable 10, the spacing between the plurality of rollers 94 can be adjusted synchronously. For example, when the push block 72 is forced to move to the left (such as Fig.12 In the direction shown in the figure), the distance between the three adjacent elastic plates 66 is reduced by cooperating with the rod body 1 73, the limit chuck 74 and the plurality of push plates 75. At this time, the push block 72 cooperates with the rod body 2 77, and the annular plate 78 and the plurality of limit frames 79 are also driven to move to the left side (as shown in the figure). Fig.12 As shown in the direction, the plurality of limit frames 79 move to the left, and the driving force applied to the corresponding limit rods 92 can make the plurality of limit rods 92 drive the corresponding spring positioning members 93 and rollers 94 to gradually approach each other, thereby achieving the effect of synchronously reducing the spacing between the plurality of rollers 94.

[0101] At the same time, if the cable 10 shakes violently during the process of the tape wrapping device 13 wrapping the tape material around the cable 10, the cable 10 will move to compress the surrounding rollers 94. When the cable 10 moves downward, it will exert a downward pressing force on the corresponding rollers 94 (such as Fig.16 As shown in the direction, the side roller 94 presses the corresponding spring positioning member 93 to move downward, and during the downward movement of the spring positioning member 93, the corresponding plate body 88 and the blocking plate 89 cooperate to drive the sealing plate 810 to move downward together, and when the sealing plate 810 moves downward, the gas inside the lower cavity 85 is squeezed (as shown in the direction shown in the direction). Fig.14 In the direction shown), the jet speed of the multiple air jet pipes 87 located below can help increase the impact force generated by the multiple air jet pipes 87 below on the lower end of the cable 10. Through this impact force, the inertial force of the shaking of the cable 10 can be offset to a certain extent, so that the cable 10 gradually returns to a stable state, which helps to further improve the wrapping effect of the equipment on the cable 10.

[0102] Similarly, when the cable 10 moves in other directions, by increasing the impact force of the airflow on the surface of the cable 10, the jitter of the cable 10 can be buffered, which helps to further improve the position stability of the cable 10 when the equipment is wrapping it, and helps to further improve the effect of the equipment wrapping it.

[0103] At the same time, the purpose of setting the rollers 94 and elastic plates 66 that are in contact with the surface of the cable 10 to be able to move under force is to facilitate the adaptation to the displacement of the cable 10 when it shakes, and to a certain extent, through the cooperation of multiple rollers 94 and multiple elastic plates 66, the shaking of the cable 10 can be limited to a certain extent.

[0104] A method for using a conductive core twisting device for cable production, such as Fig.17 As shown, the following steps are included:

[0105] S1: The operator first places the cable and the filling rope on the pay-off device 11 in sequence, and stretches one end of the cable and the filling rope into the twisting device 12, and then uses the twisting device 12 to complete the twisting of the cable and the filling rope;

[0106] S2: When the cable 10 to be twisted is forced to move to the left side of the box 2, the adjustment component 7 is used to adjust the distance between the adjacent elastic plates 66 and the rollers 94 according to the diameter of the cable 10, and then the driving component 5 and the rolling component 6 are used to control the rotation of the rolling plate 65 and the elastic plate 66 to adjust the roundness of the surface of the cable 10. At the same time, the knocking component intermittently knocks and vibrates the surface of the cable 10, which can accelerate the release of the internal stress of the cable 10, which helps to reduce the shaking of the cable 10 during the subsequent wrapping process;

[0107] S3: Afterwards, the multiple air jet pipes 87 are used to blow air evenly around the cable 10 through the air delivery component, so as to achieve non-contact clamping and positioning of the cable 10, which helps to further improve the stability of the subsequent cable 10 wrapping process and the cable 10 wrapping effect. At the same time, the movement of the cable 10 can be further limited by the limiting component 9;

[0108] S4: When the cable 10 moves to the lower end of the tape wrapping device 13, the tape wrapping device 13 can be used to complete the wrapping process on the surface of the cable 10, and then the conveying device 14 and the winding device 15 cooperate to reel in the wrapped cable 10;

[0109] S5: If the cable 10 shakes violently during the wrapping process, the limiting component 9 and the plurality of sealing plates 810 can cooperate to increase the impact force of blowing air on the surface of the cable 10, which can offset the inertia force of the shaking of the cable 10 to a certain extent, thereby gradually stabilizing the cable 10, which can help to further ensure the wrapping effect of the cable 10.

[0110] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
