Description

Technical Field

[0001] This invention relates to the field of cable production technology, specifically to a cable stranding machine. Background Technology

[0002] Cables, as an important carrier for power transmission and signal transmission, are widely used in various fields of the national economy and daily life. Their production process typically involves multiple complex steps, including conductor drawing, stranding (bundle stranding or tube stranding), insulation extrusion, cabling, armoring, and sheath extrusion. Among these, the stranding process is a crucial step in cable production. Its main purpose is to twist multiple thin, single-strand metal wires (such as copper or aluminum wires) together according to certain rules and directions to form a conductive core with a specific strength and cross-sectional area.

[0003] Currently, the common method for twisting multiple strands of wire into one is through a stranding machine. Depending on the type of equipment, these are mainly divided into bundle stranding machines and tube stranding machines. Their core working principle is that multiple single strands are released by a pay-off device, converged by a separator or guide wheel to a winding die or stranding point, and then traction is provided by a high-speed rotating traction wheel or take-up device, causing each single strand to rotate around a central axis during its journey, thus being twisted into a tightly packed round or fan-shaped core.

[0004] However, in existing stranded wire production processes, continuous friction exists between the wire and the guide rollers. This friction not only generates a large amount of heat, causing the wire temperature to rise, but more seriously, it causes direct mechanical damage to the wire surface, such as scratches, burrs, and even peeling or cracking of the metal surface. This frictional damage severely compromises the integrity and smoothness of the conductor's surface, directly affecting the cable's conductivity, corrosion resistance, and the adhesion quality of subsequent insulation layers, ultimately reducing the overall quality and service life of the cable product. Summary of the Invention

[0005] The purpose of this invention is to provide a cable stranding machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable stranding machine, comprising:

[0007] The wire feeding unit is used to feed out multiple strands of single wire;

[0008] A twisting unit includes two twisting frames arranged opposite each other along a first direction, a reciprocating assembly disposed between the two twisting frames, and a plurality of twisting structures slidably disposed between the two twisting frames. The reciprocating assembly includes multiple conveyors. The plurality of twisting structures enclose a twisting area for multiple single strands to pass through. Each twisting structure corresponds one-to-one with a conveyor. Each twisting structure includes a twisting track, a twisting wheel slidably disposed on the twisting track, and a power assembly drively connected to the twisting wheel. The power assembly drives the twisting wheel to move along the extension direction of the twisting roller track.

[0009] The traction unit is used to pull multiple single-strand wires to move along the first direction.

[0010] In one possible implementation, the twisted track includes:

[0011] An in-situ rail is connected to the corresponding transport machine, and the in-situ rail is provided with a first moving groove;

[0012] An extension rail is slidably disposed in the first movable groove; and

[0013] An extension member is connected to the extension rail and is used to drive the extension rail to move along the extension direction of the first moving groove.

[0014] In one possible implementation, the extension rail has a second moving slot connected to the first moving slot, and the first moving slot and the second moving slot form a moving channel;

[0015] The inner walls on both sides of the first moving groove are provided with a first power groove, and the inner walls on both sides of the second moving groove are provided with a second power groove. The first power groove and the second power groove form a power channel.

[0016] The power structure includes:

[0017] A movable seat is provided in the moving channel;

[0018] Two drive wheels, each located in one of the two aforementioned drive channels; and

[0019] Two connecting components are provided, each corresponding to a drive wheel. The connecting components are located between the corresponding drive wheel and the movable seat. Each connecting component includes a telescopic rod and a power component located on the telescopic rod. The telescopic rod extends and retracts along its own axial direction, and the power component is used to drive the drive wheel to rotate about the axial direction of the telescopic rod.

[0020] In one possible implementation, the telescopic member has a preload that causes the drive wheel to move away from the movable seat;

[0021] The end of the extension rail is fixedly connected to a guide plate, and there are two guide plates, which are respectively located on both sides of the extension rail.

[0022] In one possible implementation, the end of the telescopic rod away from the power wheel is rotatably connected to the movable seat, and the movable seat has an adjustment cavity for the telescopic rod to extend into;

[0023] The adjustment cavity is equipped with an adjustment unit, the adjustment unit comprising:

[0024] An adjusting tube is fixed between the two telescopic rods, and the adjusting tube is a flexible tube.

[0025] An adjusting seat is slidably disposed on the inner wall of the adjusting cavity, and the adjusting seat has an adjusting groove for the adjusting tube to pass through; and

[0026] An adjusting element is connected to the adjusting seat and is used to drive the adjusting seat to move.

[0027] In one possible implementation, the regulating tube is hollow, and the regulating unit further includes a material box connected to the regulating tube and a control component disposed between the material box and the regulating tube, the control component being used to transfer material between the material box and the regulating tube.

[0028] In one possible implementation, the adjustment unit further includes a fastening airbag disposed in the adjustment groove and a pneumatic component connected to the fastening airbag. The fastening airbag is sleeved on the outer periphery of the adjustment tube, and the pneumatic component is used to inflate and de-inflate the fastening airbag.

[0029] In one possible implementation, the guide plate is set to an arc shape.

[0030] In one possible implementation, the movable seat is equipped with a movable wheel on the side opposite to the hinge wheel, and the movable wheel abuts against the moving channel.

[0031] In one possible implementation, the hinge structure further includes an adjusting member fixed to the movable seat and the home track, the extension and retraction direction of the adjusting member being perpendicular to the seat surface of the movable seat.

[0032] Compared with existing technologies, the beneficial effects of this invention are that, by setting up a stranding unit composed of reciprocating components, multiple stranding structures, and stranding wheels sliding on the stranding track, this technical solution fundamentally changes the contact method between the single wire and the guiding element. Specifically, in traditional stranding machines, there are two types of friction between the single wire and the fixed guide wheel: one is the friction generated by the fixed guide wheel's axial position remaining unchanged, and the other is the friction generated by the fixed guide wheel's circumferential position changing. In this solution, the stranding wheel and the single wire move forward synchronously, reducing the original two types of friction to only one. This significantly reduces the heat generated by friction and effectively avoids damage to the wire surface caused by high temperature or mechanical abrasion, such as scratches, burrs, peeling, or even breakage. This ensures the integrity and smoothness of the conductor surface, which not only directly improves the conductivity and corrosion resistance of the cable but also provides an excellent interface foundation for the uniform adhesion of the subsequent insulation layer, ultimately guaranteeing the overall quality and long service life of the cable product from the source.

[0039] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figures 1-4 As shown, the present invention provides a technical solution: a cable stranding machine, including a wire feeding unit, a stranding unit 10, and a traction unit. The wire feeding unit is used to feed out multiple strands of single wire. The wire feeding unit is prior art and will not be described in detail in this application. The stranding unit 10 includes two stranding frames 101 arranged opposite each other along a first direction, a reciprocating assembly disposed between the two stranding frames 101, and multiple stranding structures slidably disposed between the two stranding frames 101. The reciprocating assembly includes multiple conveyors 102. The multiple stranding structures are arranged to form a stranding area for multiple strands of single wire to pass through. The stranding structures correspond one-to-one with the conveyors 102. The stranding structure includes a stranding track, a stranding wheel 103 slidably disposed on the stranding track, and a power assembly connected to the stranding wheel 103. The power assembly is used to drive the stranding wheel 103 to move along the extension direction of the stranding roller track. The traction unit is used to traction the multiple strands of single wire to move along the first direction.

[0041] It should be noted that a wire splitting unit is also provided between the wire feeding unit and the twisting unit 10. The wire splitting unit is used to guide the single wire to the twisting area. The wire splitting unit is existing technology and will not be described in detail in this application.

[0042] The cable stranding machine provided in this application, after the equipment is started, the wire feeding unit simultaneously feeds out multiple strands of single wire to be stranded. These single wires pass through the stranding area formed by multiple stranding structures and contact the surface of their respective stranding wheels 103. The traction unit continuously applies traction force along a first direction, pulling the multiple strands of single wire forward. During this process, the power component of each stranding structure starts working, driving the stranding wheel 103 to move along the extension direction of the stranding track, so that while contacting the single wire, the stranding wheel 103 both moves in the forward direction of the single wire and performs circumferential motion around the central axis of the stranding area.

[0043] Meanwhile, multiple conveyors 102 in the reciprocating assembly drive their respective stranding structures to reciprocate between the two stranding frames 101 according to preset stranding process parameters. This, combined with the track movement of the stranding wheels 103, determines the spatial trajectory and rotation speed of the single wire during its journey. As the multiple single wires continue to move forward under traction, the stranding wheels 103 move in tandem, causing each single wire to continuously rotate relative to the central axis and be tightly stranded together as it passes through the stranding area. This forms a stable, uniformly pitched conductive core, which is ultimately output by the traction unit to subsequent processes.

[0044] Compared with existing technologies, this technical solution fundamentally changes the contact method between the single wire and the guiding element by setting up a stranding unit 10 composed of reciprocating components, multiple stranding structures, and a stranding wheel 103 sliding on the stranding track. Specifically, in traditional stranding machines, there are two types of friction between the single wire and the fixed guide wheel: one is the friction generated by the fixed guide wheel's axial position remaining unchanged, and the other is the friction generated by the fixed guide wheel's circumferential position changing. In this solution, the stranding wheel 103 moves synchronously with the single wire, reducing the original two types of friction to only one. This significantly reduces the heat generated by friction and effectively avoids damage such as scratches, burrs, peeling, or even breakage on the wire surface caused by high temperature or mechanical abrasion. It ensures the integrity and smoothness of the conductor surface, which not only directly improves the conductivity and corrosion resistance of the cable but also provides an excellent interface foundation for the uniform adhesion of the subsequent insulation layer, ultimately guaranteeing the overall quality and long service life of the cable product from the source.

[0045] In some embodiments, see Figure 2 and Figure 3 The twisted track includes an in-situ rail 104, an extension rail 105, and an extension member. The in-situ rail 104 is connected to the corresponding conveyor 102 and has a first moving groove 1041. The extension rail 105 is slidably disposed in the first moving groove 1041. The extension member is drivenly connected to the extension rail 105 and is used to drive the extension rail 105 to move along the extension direction of the first moving groove 1041. The extension member is an arc-shaped slide rail.

[0046] After the extension component is activated, the extension rail 105 is driven to move outward along the first moving groove 1041, so that the extension rail 105 extends out of the original rail 104. At this time, the first moving groove 1041 of the original rail 104 and the second moving groove 1051 of the extension rail 105 are connected to each other, forming a complete moving channel with increased length, providing a longer movement path for the winch wheel 103. During the winch process, the power component drives the winch wheel 103 to move along this combined moving channel, so that the winch wheel 103 can guide the single line over a longer arc distance.

[0047] When the process is completed or a reset operation is required, the extension moves in the opposite direction, driving the extension rail 105 to retract along the first moving groove 1041 into the original position rail 104. At this time, the movement range of the winch wheel 103 is again restricted to the shorter stroke corresponding to the original position rail 104, which facilitates the equipment to carry out the next round of process preparation or maintenance operations.

[0048] The extension rail 105 can be driven to extend or retract from the first moving groove 1041 of the original rail 104 according to process requirements, so that the effective moving stroke of the winch wheel 103 can be flexibly changed. This retractable track structure enables the same equipment to be compatible with the process, significantly improving the equipment's versatility and process adaptability.

[0049] In some embodiments, see Figure 3 and Figure 4 The extension rail 105 has a second moving groove 1051 that is connected to the first moving groove 1041. The first moving groove 1041 and the second moving groove 1051 form a moving channel.

[0050] The inner walls on both sides of the first moving groove 1041 are provided with a first power groove 1042, and the inner walls on both sides of the second moving groove 1051 are provided with a second power groove 1052. The first power groove 1042 and the second power groove 1052 form a power channel.

[0051] The power structure includes a movable base 106, two power wheels 107, and two connecting components. The movable base 106 is located in the moving channel. The two power wheels 107 are respectively located in the two power channels. The connecting components correspond one-to-one with the power wheels 107 and are located between the corresponding power wheels 107 and the movable base 106. The connecting components include a telescopic rod and a power component located on the telescopic rod. The telescopic rod 108 extends and retracts along its own axial direction. The power component is used to drive the power wheels 107 to rotate about the axial direction of the telescopic rod. The power component is a servo motor.

[0052] Optionally, the telescopic component 108 can be a telescopic hydraulic cylinder, an electric cylinder, or a telescopic cylinder.

[0053] When the power component needs to drive the winch wheel 103 to move along the winch track, the power component drives the power wheel 107 to rotate around the axis of the telescopic rod. When the power wheel 107 rotates in the power channel, the friction between the power wheel 107 and the inner wall of the power channel is converted into driving force, which is transmitted to the moving seat 106 through the telescopic rod, thereby driving the moving seat 106 to move along the extension direction of the moving channel. The moving seat 106 then drives the winch wheel 103 connected to it to move synchronously.

[0054] During this process, the telescopic rod has axial extension and retraction capabilities. When the power wheel 107 enters the second power groove 1052 from the first power groove 1042, there is a width difference between the two sections of the track. The telescopic rod will automatically extend or shorten according to actual needs, dynamically adjusting the distance between the power wheel 107 and the moving seat 106 to ensure that the power wheel 107 crosses the track connection and continues to move forward.

[0055] Optionally, the telescopic member 108 is a spring rod, and the telescopic member 108 has a preload force that causes the power wheel 107 to move away from the moving seat 106; the end of the extension rail 105 is fixedly connected to a guide plate 1053, and there are two guide plates 1053, which are respectively located on both sides of the extension rail 105.

[0056] As the moving seat 106 gradually approaches the connection between the original rail 104 and the extension rail 105, the two guide plates 1053 fixed to the end of the extension rail 105 play a guiding role, and the power wheel 107 gradually slides in along the guide plate 1053, thereby creating the posture conditions for the power wheel 107 to smoothly enter the extension rail 105.

[0057] In some embodiments, see Figure 4 The end of the telescopic rod away from the power wheel 107 is rotatably connected to the movable seat 106, and the movable seat 106 has an adjustment cavity 1061 for the telescopic rod to extend into.

[0058] An adjustment unit 20 is provided inside the adjustment cavity 1061. The adjustment unit 20 includes an adjustment pipe 201, an adjustment seat 202, and an adjustment component 203. The adjustment pipe 201 is fixed between two telescopic rods and is a flexible pipe. The adjustment seat 202 is slidably disposed on the inner wall of the adjustment cavity 1061 and has an adjustment groove 2021 for the adjustment pipe 201 to pass through. The adjustment component 203 is drivenly connected to the adjustment seat 202 and is used to drive the adjustment seat 202 to move. The adjustment component 203 is a telescopic cylinder, an electric cylinder, or a hydraulic cylinder.

[0059] The adjusting component 203 drives the adjusting seat 202 to move. During the movement, the adjusting seat 202 causes the adjusting tube 201 to shift and deform through the adjusting groove 2021. Since the adjusting tube 201 is fixed between the two telescopic rods, the change in the position of the adjusting tube 201 will directly change the relative spatial position and angle of the two telescopic rods, thereby causing the power wheel 107 connected to the telescopic rod to change its posture, so that the power wheel 107 can enter the extension rail 105 more smoothly from the original rail 104.

[0060] In some embodiments, see Figure 4The regulating pipe 201 is hollow. The regulating unit 20 also includes a material box 204 connected to the regulating pipe 201 and a control component 205 disposed between the material box 204 and the regulating pipe 201. The control component 205 is used to transfer materials between the material box 204 and the regulating pipe 201.

[0061] It should be noted that the control component 205 includes a material pipe and a material pump, which are existing technologies and will not be described in detail in this application.

[0062] When there is no need to adjust the attitude of the drive wheel 107, the control component 205 is activated and draws material from the material box 204. The material enters the hollow structure of the control tube 201 through the control component 205 until it fills the control tube 201, thereby enhancing the rigidity of the control tube 201 and making it less prone to deformation, thus ensuring the stability of the drive wheel 107.

[0063] When the attitude of the power wheel 107 needs to be adjusted, the control component 205 is activated and draws material from the control tube 201. The material returns to the material box 204 via the control component 205, thereby reducing the stiffness of the control tube 201 and making the control tube 201 more prone to deformation.

[0064] In some embodiments, see Figure 4 The adjustment unit 20 also includes a fastening airbag 206 disposed in the adjustment groove 2021 and a pneumatic component connected to the fastening airbag 206. The fastening airbag 206 is sleeved on the outer periphery of the adjustment tube 201. The pneumatic component is used to inflate and de-inflate the fastening airbag 206. The pneumatic component is an air pump.

[0065] When there is no need to adjust the attitude of the drive wheel 107, the control component 205 is activated to enhance the stiffness of the adjustment tube 201. At this time, the pneumatic component is activated to inflate the fastening airbag 206, further enhancing the stability of the drive wheel 107.

[0066] When the attitude of the drive wheel 107 needs to be adjusted, the control component 205 is activated to reduce the stiffness of the adjustment tube 201. At this time, the pneumatic component is activated to extract the gas in the fastening airbag 206, providing freedom for the deformation of the adjustment tube 201.

[0067] In some embodiments, see Figure 3 The guide plate 1053 is designed to be arc-shaped.

[0068] The arc-shaped guide plate 1053 provides a progressive guiding path for the moving seat 106 with its continuous curved profile. This progressive contact ensures that the position and attitude correction of the moving seat 106 is continuous and gradual during its entry into the extension rail 105, rather than abruptly changing at a certain critical point. This effectively avoids impact loads and vibrations caused by hard collisions or sudden changes in direction.

[0069] In some embodiments, see Figure 3 and Figure 4 The movable seat 106 is equipped with a movable wheel 1062 on the side opposite to the hinge wheel 103, and the movable wheel 1062 abuts against the movable channel.

[0070] The contact point between the movable wheel 1062 and the inner wall of the moving channel constitutes the auxiliary support point of the movable seat 106. When the power wheel 107 rotates in the power channel and drives the movable seat 106 to move forward, the movable wheel 1062 rolls synchronously along the inner wall of the moving channel. The rolling process converts the sliding friction between the movable seat 106 and the moving channel into rolling friction, which greatly reduces the motion resistance.

[0071] In some embodiments, see Figure 3 The hinge structure also includes an adjusting member 109 fixed to the movable seat 106 and the original rail 104. The extension and retraction direction of the adjusting member 109 is perpendicular to the seat surface of the movable seat 106. The adjusting member 109 is a telescopic oil cylinder, electric cylinder or hydraulic cylinder.

[0072] The extension and retraction of the adjusting element 109 directly drives the twisting structure to move radially, causing the twisting wheel 103 to move closer to or further away from the central axis of the twisting area. When multiple twisting structures need to be adjusted synchronously, the control system can simultaneously send commands to all adjusting elements 109, causing each twisting wheel 103 to move synchronously towards or away from the center with the same amount of displacement.

[0073] When production tasks change and require switching to different specifications of wire cores, the target extension amount required by each adjusting component 109 is recalculated according to the new process parameters, and the adjusting component 109 is driven to perform a new round of radial adjustment, so that the stranded structure can quickly and accurately adapt to the new process requirements and realize the efficient switching of equipment between different specifications of products.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
