Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cable manufacturing, and in particular to a production device for photovoltaic cables. Background Art

[0002] Photovoltaic cables are key components that connect solar panels to power systems and are responsible for transmitting the electricity generated by solar panels. In solar power generation systems, the performance of photovoltaic cables directly affects the efficiency and stability of the entire system. Therefore, the production of high-quality photovoltaic cables is essential to ensure the normal operation of solar power generation systems.

[0003] The production of photovoltaic cables is generally completed through multiple functional devices, including wire drawing machines, stranding machines, insulation extruders, wrapping machines and sheath extruders. In the production process of photovoltaic cables, the stranding machine is a key equipment connecting the wire drawing machine and the subsequent insulation and sheathing processes. Its importance is self-evident. The stranding machine needs to ensure that each copper wire maintains uniform tension and appropriate stranding force during the stranding process to ensure that the stranded conductor has uniform resistance distribution and good mechanical strength. In addition, the stranding machine also needs to accurately control the twisting pitch, which directly affects the bending performance and electromagnetic compatibility of the cable.

[0004] In the actual production process, it is difficult to intervene in the stranding process manually due to the danger of the stranding process. The stranding machine may damage the conductor wire due to excessive pay-off tension and twisting force. Excessive pay-off tension may cause the copper wire to be overstretched before twisting, resulting in plastic deformation or breakage, which will not only reduce the conductive performance of the conductor, but also affect the overall mechanical strength of the cable. Therefore, it is necessary to propose a production device for photovoltaic cables that can detect and control pay-off tension and twisting force. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a production device for photovoltaic cables. By designing a component that can pre-lay out the wires to assist in laying out the wires, and combining it with a system for collecting and analyzing the twisting force, the wire laying tension and the twisting force can be controlled, thereby improving the final conductive properties of the conductor and the overall quality of the produced cables.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a production device for photovoltaic cables, comprising a box body, a side wall of the box body is provided with a wire outlet hole and a plurality of wire inlet holes, the wire outlet hole and the plurality of wire inlet holes are respectively located on both side walls of the box body, a wire take-up assembly for receiving a plurality of conductor wires after twisting is provided on one side of the box body near the wire outlet hole, and a wire pay-off assembly for paying out wires into the box body is provided on one side of the box body near the wire inlet hole;

[0007] A fixed cylinder is fixedly connected to one side of the box body near the wire entry hole, a rotating cylinder is sleeved on the outer side of the fixed cylinder, the rotating cylinder is rotatably connected to the fixed cylinder, a plurality of wire passing grooves corresponding to the wire passing holes are opened on the side wall of the rotating cylinder, a first driving component for driving the rotating cylinder to rotate is also provided in the box body, the first driving component signal is connected to an intelligent system, a traction component for pulling the conductor wire to provide auxiliary pulling force is provided in the rotating cylinder, the traction component can reciprocate and slide along the extension direction of the conductor wire to pull the conductor wire, a limiting component fixedly connected to the side wall of the box body is provided in the fixed cylinder, when the rotating drum drives the traction component to rotate, the limiting effect of the limiting component drives the traction component to reciprocate and slide;

[0008] A disc is fixedly connected to one end of the rotating drum away from the inner wall of the box body, and a number of wire holes corresponding to the wire entry holes are opened circumferentially on the disc. Detection grooves are opened on the inner walls of the wire holes near the center of the disc, and detection blocks are slidably connected in the detection grooves. Pressure sensors fixedly connected to the bottom wall of the detection grooves are provided at the bottom of the detection blocks, and the several pressure sensors are connected to the intelligent system signals.

[0009] The technical principle of the above scheme is as follows: the first drive component is connected to the intelligent system signal, and the rotation speed and direction of the drum are accurately adjusted through the control of the intelligent system. When the drum rotates, it will drive the traction component to rotate together, and at the same time, the limiting function of the limiting component is used to make the traction component reciprocate and slide along the extension direction of the conductor line in the drum, so as to pull the conductor line for twisting. The traction component can reciprocate and slide along the extension direction of the conductor line to provide auxiliary tension for releasing the wire. During the process, several pressure sensors are connected to the intelligent system signal to monitor the pressure of the conductor line in the twisting process in real time. Based on this information, the intelligent system can accurately control the working state of the first drive component, the wire release component and the wire take-up component to achieve the optimal twisting effect and production efficiency.

[0010] The above scheme has the following beneficial effects:

[0011] 1. This solution uses pressure sensors to collect pressure data from each wire hole in real time, and the intelligent system can make precise intelligent adjustments to the stranding process based on this data. When abnormal pressure is detected, the intelligent system can respond quickly and adjust the stranding speed or tension, thereby effectively avoiding the risk of the conductor wire breaking due to excessive force. This not only improves the stability of the production process, but also significantly reduces the scrap rate and production costs, helps maintain the tension and stability of the conductor wire, and ensures the stranding quality.

[0012] 2. In this solution, the traction assembly is uniquely designed. It clamps and displaces the conductor wire through reciprocating sliding displacement, which not only helps to maintain the stable position of the conductor wire, but also effectively reduces the tension during the pay-off process. The traction assembly periodically clamps and releases the conductor wire when the drum rotates. This periodic clamping and releasing can effectively reduce the tension fluctuations on the conductor wire during pay-off, thereby further reducing the damage to the conductor wire caused by the pay-off tension. In addition, the stretching of the traction assembly will produce a certain pre-pay-off effect, which can alleviate the tension during pay-off to a certain extent, making the stranding process smoother and improving the safety of the stranding.

[0013] 3. This solution makes full use of the driving force of the stranded wire, that is, the power of the first drive assembly, to achieve the sliding drive of the traction assembly. This design allows the conductor wire unwinding assistance and the stranding to be performed synchronously without the need for an additional power source. The synchronization of the unwinding assistance and the stranding steps can not only improve production efficiency, but also simplify the production process. In addition, by accurately controlling the rotation speed and power of the first drive assembly, the speed and tension of the stranded wire can be accurately adjusted to meet the needs of different conductor wire materials and production.

[0014] Furthermore, a turntable is provided on the outer wall of the box body near the wire inlet hole, and the turntable is rotatably connected to the side wall of the box body. The wire inlet holes are circumferentially opened with the center of the turntable as the center of the circle, and the side wall of the box body is also provided with an annular groove corresponding to the rotation trajectory of the wire inlet hole.

[0015] Beneficial effects: By rotating the turntable, the position of the wire entry hole can be easily adjusted to adapt to different working environments and wire stranding requirements without moving the entire device, which enhances the convenience and flexibility of use. In addition, the traditional fixed-position wire entry hole may wear out due to long-term use and frequent entry and exit of conductor wires, and even cause failure. The design of the turntable and annular groove disperses this wear, extends the service life of the device, and reduces downtime caused by wire entry hole problems.

[0016] Furthermore, the wire-paying assembly includes a plurality of support frames, which are all fixedly connected to positions corresponding to the wire entry holes on the turntable, and the support frames are all detachably connected with wire-paying drums for winding the conductor wires to be twisted.

[0017] Beneficial effect: By winding the conductor wire to be twisted on the pay-off drum, when the conductor wire is pulled inward along the box, the pay-off drum will automatically rotate to release the required length of the conductor wire. Automated wire pay-off is achieved, manual intervention is reduced, and production efficiency is improved. In addition, the staff can easily replace or supplement the conductor wire to be twisted by removing the pay-off drum, connecting a new conductor wire, and reinstalling the pay-off drum, which reduces the difficulty and cost of operation and further improves work efficiency.

[0018] Furthermore, the wire-taking assembly includes a wire-taking seat, which is fixedly connected to the bottom of the outer wall of the box body near the wire outlet hole. The top of the wire-taking seat is rotatably connected to a wire-taking drum for winding and twisting several conductor wires. A second drive assembly for driving the wire-taking drum to rotate is provided in the wire-taking seat, and the second drive assembly is connected to the intelligent system signal.

[0019] Beneficial effects: The intelligent system controls the rotation of the take-up drum, realizes the automation and intelligence of the take-up of several conductor wires after twisting, improves production efficiency, reduces the reliance on manual operation, and reduces the possibility of human error. In addition, the signal connection of the intelligent system enables the second drive component to accurately adjust the rotation speed and force of the take-up drum according to the material, diameter, length and other parameters of the several conductor wires after twisting, as well as the actual situation in the production process, to ensure that the several conductor wires after twisting can be evenly and tightly wound on the take-up drum.

[0020] Furthermore, the length of the rotating drum is greater than that of the fixed drum, and the traction assembly includes a traction ring slidably connected to the inner wall of the rotating drum, and a plurality of wire clamping grooves corresponding to the wire passing grooves are provided on the side of the traction ring close to the rotating drum, and springs are fixedly connected on both sides of the inner wall of the wire clamping groove, and elastic blocks are fixedly connected on one end of the springs on both sides away from the wire clamping groove, and the two elastic blocks fit each other, and a separation block fixed to the disc is provided in the wire passing groove, and the separation block is located in the moving track of the elastic block.

[0021] Beneficial effects: Through the reciprocating sliding displacement of the traction ring and the periodic clamping and releasing action of the elastic block, the conductor wire can be effectively assisted in stretching and guiding, which helps to maintain the stable position of the conductor wire during the stranding process, and can also offset the tension fluctuation caused by the stranding action to a certain extent. At the same time, through the precise control of the first drive component by the intelligent system, the rotation speed of the drum can be adjusted, thereby further controlling the tension and stranding tightness during the stranding process, which helps to improve the production efficiency and quality of photovoltaic cables and reduce production costs.

[0022] Furthermore, the limit assembly includes a limit rod fixedly connected to the inner wall of the box body, the limit rod is located in a fixed cylinder, and the end of the limit rod away from the inner wall of the box body is fixedly connected to a bent rod, the height of the bent rod away from the end of the limit rod is greater than the height close to the end of the limit rod, a ring is rotatably connected to the bent rod, the side wall of the ring is hinged with a sliding rod, and the end of the sliding rod away from the ring is spherically hinged to the inner wall of the traction ring.

[0023] Beneficial effect: The connection between the limit rod and the curved rod, combined with the rotation of the drum as the driving force source, enables the ring and the slide rod to naturally adjust their positions as the drum rotates, providing a smooth guide path for the traction ring, and achieving the left and right displacement required after clamping the conductor line.

[0024] Furthermore, the inner wall of the box body is fixedly connected with a cable rail located at the outlet hole, and one end of the cable rail away from the outlet hole is fixedly connected with a hollow cable ring. Several conductor wires extending through the wire hole are gathered and extended from the hollow part of the cable ring to the outlet hole.

[0025] Beneficial effect: After the twisting is completed, all the conductor wires passing through the wire hole will be bundled and pass through the hollow part of the cable tying ring, and then extend to the outlet hole, so that the several conductor wires after twisting are neat and orderly, and the crossing, entanglement and wear of the several conductor wires after twisting are avoided during the outlet process, thereby protecting the integrity and electrical performance of the several conductor wires after twisting. The design of the cable rail and the cable tying ring simplifies the outlet process of the several conductor wires after twisting, allowing the staff to find and organize the several conductor wires after twisting more quickly, reducing operation time and labor costs, and improving production efficiency.

[0026] Furthermore, the curved rod includes a rod body, the top of the rod body is fixedly connected to an electric telescopic rod, the electric telescopic rod is connected to the intelligent system signal, and the ring is sleeved on the outside of the output end of the electric telescopic rod.

[0027] Beneficial effect: Since the reduction of the pay-off tension is crucial to protecting the conductor wire from excessive stretching and potential damage, especially when dealing with thin or fragile conductor wires, through the telescopic function of the electric telescopic rod, when the electric telescopic rod is extended, the displacement starting point of the traction ring will shift to the left, so that the timing of the two elastic blocks contacting the disengagement blocks is advanced, shortening the distance that the two elastic blocks clamp the conductor wire and pull it to the left, and the pay-off tension on the conductor wire is effectively reduced. On the contrary, the length of the stranded wire pay-off will be increased, thereby increasing the efficiency of the stranded wire.

[0028] Furthermore, the intelligent system includes a preset module, a collection module, a processing module and a driving module;

[0029] A preset module for users to input the material of the conductor wire to be twisted;

[0030] A collection module, used for collecting pressure data of a plurality of through-holes through a plurality of pressure sensors;

[0031] A processing module is used to calculate the anti-twisting stress of a plurality of conductors to be twisted according to the input conductor material, and then compare the anti-twisting stress with the pressure data collected by the acquisition module, and convert the data difference into a driving signal to be transmitted to the driving module;

[0032] The driving module is used to drive and control the electric telescopic rod, the first driving assembly and the second driving assembly based on the driving signal transmitted by the processing module.

[0033] Beneficial effects: Through the preset modules, the stranding device can be personalized and adjusted according to the different conductor wire materials, which helps to meet the needs of different customers and improve the market competitiveness of the product. The acquisition module reflects the stress of the conductor wire during the stranding process, and the processing module compares these pressure data with the preset anti-twisting stress, thereby realizing real-time monitoring and feedback of the stranding process, which helps to timely discover and solve potential production problems and ensure product quality and stability. The design of the entire intelligent system realizes the automation and intelligence of the device. The user only needs to input the conductor wire material through the preset module, and the system can automatically complete the subsequent stranding process without human intervention, which not only improves production efficiency, but also reduces operation difficulty and cost.

[0034] Furthermore, in the processing module, the minimum anti-twisting stress is calculated based on the input materials of several conductor wires, and the minimum anti-twisting stress is used as the pressure threshold. When the pressure data collected by any pressure sensor is greater than the pressure threshold, the pressure difference is calculated, and then the pressure difference is converted into the driving power data that needs to be reduced by the first driving component and the second driving component, as well as the elongation of the electric telescopic rod, and each driving data is transmitted to the driving module.

[0035] Beneficial effect: By accurately calculating the minimum anti-twisting stress of the conductor wire material and using it as the pressure threshold, the system can monitor and respond to the stress of the conductor wire during the twisting process in real time. Once the pressure exceeds the threshold, the system immediately takes measures, such as reducing the drive power and adjusting the extension of the electric telescopic rod, thereby effectively avoiding damage to the conductor wire due to excessive stress, and optimizing the performance of the twisting equipment, that is, the synchronization of the strength of the wire laying assistance and the twisting strength can be adjusted by the extension and shortening of the electric telescopic rod to achieve adaptation to all

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The following is further described in detail through specific implementation methods:

[0050] Embodiment 1:

[0051] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown: A production device for photovoltaic cables, including a box 1, as shown in the attached Figure 1 and Figure 2 As shown, the right side wall of the box body 1 is rotatably connected to a turntable 13 through a bearing, and a plurality of wire entry holes 3 are circumferentially provided on the surface of the turntable 13. Correspondingly, an annular groove corresponding to the rotation trajectory of the wire entry holes 3 is also provided on the right side wall of the box body 1, so that the conductor wire will not be twisted when passing through the wire entry holes 3 into the box body 1.

[0052] Take one of the cable entry holes 3 as an example. Figure 2 As shown, a plurality of support frames 14 corresponding to the wire entry holes 3 are welded on the surface of the turntable 13, and the support frames 14 correspond to the wire entry holes one by one. The support frames 14 include support plates symmetrically arranged along the wire entry holes 3, and a wire pay-off drum 15 is provided between the two support plates. Both ends of the wire pay-off drum 15 are detachably and rotatably connected to the two support plates on one side close to each other through bearings. This design enables the wire pay-off drum 15 and the two support plates to rotate relative to each other, and the twisted conductor wire is wound around the wire pay-off drum 15 and extends into the box body 1 through the wire entry hole 3. During the wire twisting process, when the conductor wire is subjected to an inward pulling force along the box body 1, this pulling force will be converted into the rotational power of the wire pay-off drum 15, thereby automatically releasing the required length of the conductor wire, realizing the automatic wire pay-off process, avoiding the tension fluctuation caused by inaccurate manual control of the wire pay-off speed in the traditional wire twisting process, and effectively reducing the risk of breaking the conductor wire due to excessive tension. In addition, this design enables the staff to complete the replacement and replenishment of the conductor wires to be twisted by removing the pay-off reel 15, connecting the subsequent conductor wires with the untwisted conductor wires, and then installing a new pay-off reel 15, which not only improves work efficiency but also reduces operation difficulty and cost.

[0053] A wire take-up seat 16 is welded to the bottom of the left outer wall of the box body 1, and a wire take-up drum 17 for winding a plurality of conductor wires after twisting is rotatably connected to the top of the wire take-up seat 16 through a bearing. Figure 3 As shown, the take-up seat 16 is provided with a second drive assembly 18 for driving the take-up drum 17 to rotate. The second drive assembly 18 includes a second servo motor. The output shaft of the second servo motor is coaxially fixedly connected to the take-up drum 17 through a coupling. The second servo motor drives the take-up drum 17 to rotate by rotating, and the photovoltaic cable core after being twisted will be wound on the side wall of the take-up drum 17. The rotating take-up drum 17 provides the necessary power and tension to ensure that the photovoltaic cable core after being twisted can be tightly and orderly wound on its side wall. With the continuous rotation of the take-up drum 17, the photovoltaic cable core is gradually rolled in to form a neat and tight coil. The rotation of the take-up drum 17 is the main driving force source for all conductor wires to pull and displace into the box 1.

[0054] After a plurality of conductors to be twisted enter the box body 1 through the wire entry hole 3, first, Figure 4 As shown, Figure 5 As a side sectional view to demonstrate the internal structure, a fixed cylinder 4 is welded on the right side of the box body 1, and a rotating cylinder 5 is sleeved on the outside of the fixed cylinder 4. The right end of the rotating cylinder 5 is rotatably connected to the side wall of the box body 1 through a bearing. The thickness of the rotating cylinder 5 is greater than that of the fixed cylinder 4. The wall of the rotating cylinder 5 is provided with a plurality of wire grooves 6 connected to the wire inlet holes 3. The positions and numbers of the wire grooves 6 correspond to the wire holes 9 one by one. The right side wall of the box body 1 is also fixedly connected to a first drive assembly 7 by bolts. The first drive assembly 7 includes a first servo motor. The output shaft of the first servo motor is fixedly connected to a rotating rod through a coupling. A gear is welded on the left end of the rotating rod. The outer wall surface of 5 is provided with a tooth groove that meshes with the gear. When the first servo motor drives the gear to rotate, the rotation of the gear is transmitted to the rotating drum 5 through the tooth groove, so that the rotating drum 5 rotates, and the conductor wire to be twisted extends into the wire groove 6 through the wire entry hole 3. Combined with the design of the support frame 14 and the wire release drum 15 installed corresponding to the wire entry hole 3, under the continuous rotation of the rotating drum 5, each conductor wire to be twisted is guided through the corresponding wire groove 6 in an orderly manner, keeping the conductor wire straight, and effectively avoiding the accumulation of heat caused by mutual entanglement or friction, and reducing the probability of conductor wire damage caused by twisting or excessive wear. In addition, the precise design and layout of the wire groove 6 ensure that the travel path of each wire is precisely controlled, reducing the additional tension caused by the disorder of the path, which is conducive to maintaining the integrity of the conductor wire and the electrical performance of the photovoltaic cable after forming.

[0055] The first servo motor signal is connected to an intelligent system. The intelligent system can control the rotation speed of the first servo motor by controlling the signal of the rotation power of the first servo motor, thereby controlling the rotation speed of the rotating drum 5, laying the foundation for adjusting the stranding tightness during the stranding process, and realizing a stable, efficient and controllable stranding process.

[0056] The length of the rotating drum 5 is greater than that of the fixed drum 4. In the part where the rotating drum 5 and the fixed drum 4 do not overlap, the inner wall of the rotating drum 5 is slidably connected with a traction ring 19. Specifically, the sliding connection is that a slide groove is opened on the inner wall of the rotating drum 5, and a slider corresponding to the slide groove is welded on the outer wall of the corresponding traction ring 19. The slider and the slide groove are slidably connected by a ball bearing. Figure 7 As Figure 4 The enlarged disassembly diagram of the rotating drum 5 is shown in FIG. Figure 4 The angle shown is described, a limiting rod 24 located in the fixed cylinder 4 is welded to the side wall of the box body 1, and a bent rod 25 is welded to the left end of the limiting rod 24. The height of the left end of the bent rod 25 is greater than the height of the right end, so that the bent rod 25 is in an inclined state, and a collar 26 is rotatably connected to the bent rod 25 through a bearing. The collar 26 can only rotate relative to the bent rod 25, but cannot slide on the bent rod 25. A sliding rod 27 is hinged on the side wall of the collar 26, and the end of the sliding rod 27 away from the collar 26 is hinged to the inner wall of the traction ring 19 through a spherical hinge. When the rotating drum 5 rotates, the traction ring 19 will also rotate synchronously, and because the limiting rod 24 and the box body 1, the curved rod 25 welded with the limiting rod 24 will not rotate, and due to the hinge connection between the sliding rod 27 and the collar 26, combined with the ball joint connection between the sliding rod 27 and the traction ring 19, during the rotation of the drum 5, a circular motion with the hinge point between the sliding rod 27 and the collar 26 as the center, the length of the sliding rod 27 as the radius and the ball joint connection between the sliding rod 27 and the traction ring 19 as the circumferential point is performed. Combined with the inclined design of the curved rod 25, the circular motion is partially converted into the left and right sliding of the traction ring 19 in the drum 5, and finally presents the reciprocating left and right sliding displacement of the traction ring 19 during the rotation of the drum 5.

[0057] A plurality of wire clamping grooves 20 are provided on the outside of the traction ring 19. The positions of the wire clamping grooves 20 correspond to the positions of the wire passing grooves 6. For example, one of the wire clamping grooves 20 is Figure 5 , Figure 7 and Figure 8As shown, springs 21 are provided on both sides of the inner wall of the clamping groove 20, and the two springs 21 are symmetrically arranged. The bottom ends of the springs 21 are welded to the inner wall of the clamping groove 20, and the tops of the springs 21 are welded with elastic blocks 22. The two elastic blocks 22 fit each other, and a breakaway block 23 located in the moving track of the elastic block 22 is welded in the wire groove 6. When the traction ring 19 slides to the left, the two elastic blocks 22 follow the sliding of the traction ring 19 and contact the breakaway block 23. The two elastic blocks 22 that fit together will be separated by the force of the breakaway block 23, so that the springs 21 on both sides are compressed, thereby losing the clamping effect on the conductor line. When the traction ring 19 slides to the right, the compressed springs 21 on both sides begin to gradually return to their original state, pushing the elastic blocks 22 to approach each other until they When they are tightly fitted again, the restoring force of the elastic block 22 will produce a clamping effect on the conductor wire in the clamping groove 20 again. Since the reciprocating motion of the traction ring 19 is continuous and periodic, the elastic block 22 in the clamping groove 20 will also undergo a periodic clamping and releasing process, and finally appear to be released after moving a distance to the right, and then move a distance to the left to resume clamping. The driving force of the twisting action is used to achieve auxiliary stretching of the conductor wire to be twisted (the release of the conductor wire to be twisted is mainly driven by the take-up end), and through the periodic clamping and releasing process, the risk of breaking the conductor wire due to excessive tension during the twisting process can be effectively reduced, so that the conductor wire can maintain the necessary tension to form a tight twisted wire structure, and will not be damaged due to excessive tension. In addition, the design of the clamping effect not only helps to maintain the stable position of the conductor wire during the twisting process, but also offsets the tension fluctuations caused by the twisting action to a certain extent, further reducing the possibility of the conductor wire being broken.

[0058] In particular, such as Figure 6 As shown, Figure 4 As described from the angle shown, a disc 8 is welded on the left end of the rotating drum 5, and a plurality of wire holes 9 corresponding to the positions of the wire entry slots are opened on the disc 8 along its circumference. A plurality of detection slots 10 corresponding to the wire holes 9 are also opened on the disc 8. The detection slots 10 are all located on the side of the corresponding wire holes 9 close to the center of the disc 8. A detection block 11 is slidably connected in the detection slot 10. A pressure sensor 12 fixedly connected to the bottom wall of the detection slot 10 by rivets is provided at the bottom of the detection block 11. The plurality of pressure sensors 12 are connected to the intelligent system signal. The pressure conditions of the plurality of conductor lines on the wall of the wire hole 9 are detected by the pressure sensor 12, and the data are transmitted to the intelligent system to calculate the pressure conditions and judge the twisting force of the conductor line.

[0059] The device realizes the wire winding operation after completing the stranding, as follows Figure 4As described from the angle shown, a cable rail 28 corresponding to the position of the wire outlet hole 2 is welded to the inner wall on the left side of the box body 1, and a hollow cable ring 29 is welded to the right end of the cable rail 28. Several conductor wires extending through the wire hole 9 are gathered and extended from the hollow part of the cable ring 29 to the wire outlet hole 2. After the twisting process is completed, several conductor wires will be guided in an orderly manner by the cable rail 28 and the cable ring 29 to start the wire winding operation. The design of the cable rail 28 provides a stable moving path for the conductor wires, exerts a certain guiding and supporting effect on the conductor wires, and helps to ensure that the conductor wires remain neatly arranged during the wire winding process to avoid crossing, entanglement or excessive twisting.

[0060] Embodiment 2:

[0061] like Figure 7 As shown, the difference from Example 1 is that the curved rod 25 includes a rod body 2501 and an electric telescopic rod 2502, the bottom end of the electric telescopic rod 2502 is welded to the top of the rod body 2501, and the electric telescopic rod 2502 has the function of extending and shortening the output end. When the electric telescopic rod 2502 is extended, the displacement starting point of the traction ring 19 will shift to the left, so that the timing of the two elastic blocks 22 contacting the disengagement block 23 is advanced, and the distance that the two elastic blocks 22 clamp the conductor wire and pull it to the left is shortened, and the wire-releasing tension borne by the conductor wire is effectively reduced. On the contrary, when the electric telescopic rod 2502 is shortened, the displacement starting point of the traction ring 19 will shift to the right, increasing the aggregation of the two elastic blocks 22 clamping the conductor wire and pulling it to the left, increasing the wire-releasing tension borne by the conductor wire, but increasing the length of the stranded wire, thereby increasing the stranding efficiency.

[0062] Embodiment 3:

[0063] The difference from Example 2 is that the intelligent system includes a preset module, a collection module, a processing module and a driving module;

[0064] The user inputs the material information of the conductor wire to be twisted through the preset module. The preset module accepts the user's input and also performs preliminary processing and storage of this information to provide basic data for subsequent calculations and controls, ensuring that the system can perform customized twisting and winding operations for conductor wires of different materials, thereby meeting diverse production needs.

[0065] The acquisition module monitors the pressure data of several wire holes 9 in real time through several pressure sensors 12. The pressure sensors 12 can capture the extrusion and tension of the conductor wire during the twisting process. The acquisition module transmits these real-time data to the processing module, providing a reliable basis for the dynamic adjustment of the intelligent system. Through continuous monitoring and data analysis, it helps to ensure the stability and safety of the twisting process.

[0066] The processing module calculates the minimum anti-twisting stress through the built-in algorithm based on the conductor wire material information provided by the preset module. This stress value is used as the pressure threshold to determine whether there is an overpressure risk during the twisting process. When the pressure data collected by any pressure sensor 12 exceeds this threshold, the processing module will immediately calculate the pressure difference and convert it into the adjustment of the elongation of the electric telescopic rod 2502 and the driving power of the first drive component 7 and the second drive component 18 according to the difference. It is designed to keep the pressure in the twisting process within a safe range while optimizing the twisting effect and the quality of the winding.

[0067] The driving module receives the driving signal transmitted by the processing module, and accordingly performs precise driving control on the electric telescopic rod 2502, the first driving component 7 and the second driving component 18, ensuring that the intelligent system can quickly adapt to various changes in the stranding process and maintain the stability and continuity of production.

[0068] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
