Description
Technical Field
[0001] This invention relates to the field of wire processing technology, and in particular to a silicone wire twisting machine. Background Technology
[0002] Currently, in practical production applications, traditional silicone wire twisting equipment often adopts a split rotating structure. The rotating parts lack a dedicated coaxial positioning mechanism, which leads to uneven winding during high-speed rotation. This directly results in disordered winding trajectory and uneven twisting density. At the same time, traditional equipment cannot flexibly and accurately adjust the coaxiality of the overall position of the twisting mechanism. It is difficult to keep the center axis of the twisting mechanism consistent with the subsequent pressing, shaping, and winding stations. This may cause quality defects such as loose strands and eccentricity in the twisted cable. Therefore, it cannot meet the requirements of high-quality, high-precision, mass automated production of silicone wires. Summary of the Invention
[0003] The purpose of this invention is to provide a silicone wire twisting machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A silicone wire twisting machine includes a support frame with a top plate. The top plate has a twisting mechanism, which includes a placement plate with a rotating disk. The rotating disk has an arc-shaped groove and a threaded hole. The bottom of the rotating disk has a limiting post, and the top of the rotating disk has a lead coil. The rotating disk also has a second rotating disk with a pre-drilled opening and a threaded hole. The second rotating disk has a wire feeding drum.
[0006] In a preferred embodiment, the rotating disk 2 is provided with a handle, the outer wall of the limiting post is in close contact with the inner wall of the reserved opening, and a hand-tightening screw is provided between the threaded hole 1 and the threaded hole 2.
[0007] In a preferred embodiment, a side plate is connected to the top plate, and a connecting plate is connected to the side plate. A wire feeding drum is mounted on the connecting plate. A rotary motor is mounted on the other end of the top plate. A coupling is connected to the output end of the rotary motor, and the wire feeding drum is connected to the coupling. A twisting block is also mounted on the top plate, and a sleeve is mounted on the twisting block. By starting the rotary motor fixedly mounted on the top plate, the output end of the rotary motor is connected to the coupling. The coupling drives the wire feeding drum to rotate at a uniform and stable speed through a connecting rod transmission. The wire feeding speed can be preset and adjusted by an external control system according to the production rhythm to avoid slack due to excessively fast feeding or breakage due to excessively slow feeding. The wire passes sequentially through the sleeve on the twisting block and inside the twisting block, completing the initial directional threading of the wire. The stranded wire is installed on the first unwinding drum on the second rotating disk. The stranded wire is pulled out and passes through the first lead coil on the first rotating disk. After being guided by the first lead coil, the stranded wire merges with the wire and passes through the sleeve and stranding block simultaneously, realizing the merging and positioning of the wire and the stranded wire, preparing for subsequent twisting. The stranded wire is installed and fixed in the first unwinding drum on the second rotating disk, and can rotate freely to achieve passive unwinding. After passing through the first lead coil, the stranded wire enters the twisting position in a parallel state with the wire. The first lead coil limits, guides, and prevents tangling of the stranded wire, ensuring that the stranded wire enters the twisting path in a stable posture. Start the rotating motor one fixedly installed at the bottom of the shelf. The rotating motor one drives the rotating disk one to rotate through the linkage transmission. Under the locking action of the limit post and the hand-tightening screw, the rotating disk one drives the rotating disk two, the unwinding drum one, and the lead coil one to rotate in a circular revolution in sync. The lead coil one carries the stranded wire and rotates continuously 360° around the wire. With the axial traction force of the take-up drum, the stranded wire is evenly, tightly and continuously spirally wound on the outer wall of the wire to form a stable twisting structure and complete the core twisting process.
[0008] In a preferred embodiment, the top plate is provided with a connecting block, and the connecting block is provided with a tensioning wheel.
[0009] In a preferred embodiment, a vision sensor is provided at the bottom of the connecting block.
[0010] In a preferred embodiment, a pressure block is connected to the top plate, and a wire groove is formed on the pressure block.
[0011] In a preferred embodiment, the top plate is further provided with a pressure regulating mechanism, which includes a baffle. A rotary motor three is mounted on the top of the baffle. The output end of the rotary motor three is connected to a lead screw. A lead screw nut is mounted on the lead screw, and a slider is mounted on the lead screw nut. A slide rail is also provided on the baffle, and the slider slides along the slide rail. A cylinder one is mounted on the slider. The output end of the cylinder one is connected to a limit plate one via a piston rod. A limit plate two is connected to the limit plate one, and a limit plate three is connected to the limit plate two. A pressure roller one is mounted on the limit plate three. A limit block is also provided on the slider, and a limit plate four is connected to the limit block. A pressure roller two is mounted on the limit plate four. By activating the rotary motor three fixedly mounted on the top of the baffle, the output end of the rotary motor three drives the lead screw to rotate at a uniform speed. The lead screw and the lead screw nut form a precision threaded transmission pair, causing the slider to move smoothly up and down along the slide rail fixed on the baffle. When the cylinder one is fixedly installed on the starter slider, the piston rod of cylinder one extends and drives limit plate one to move, which in turn drives limit plate two, limit plate three and pressure roller one to move closer to the cable. Pressure roller one and pressure roller two of limit plate four on the limit block cooperate with each other to form an adaptive elastic clamping structure, which applies a uniform and moderate clamping force to the twisted cable.
[0012] In a preferred embodiment, the top plate is also provided with a tensioning mechanism, which includes a second cylinder. The output end of the second cylinder is connected to a second pressure block via a piston rod. The second pressure block has a wire groove and a pressure plate connected to it.
[0013] In a preferred embodiment, one end of the top plate is provided with a tensioning wheel 2 and a connecting plate 2, and the connecting plate 2 is provided with a take-up drum. The other end of the top plate is provided with a rotary motor 4, and the output end of the rotary motor 4 is connected to a coupling 2, and the coupling 2 is connected to a take-up drum. Before operation, the cable must be threaded through according to the preset fixed path. The specific steps are as follows: Smoothly pull out the wire to be processed from the second pay-off drum, and let it pass through the inner channel of the sleeve on the twisting block and the center hole of the twisting block in sequence. Pull out the stranded wire from the first pay-off drum. After the stranded wire is guided and positioned by the first lead coil on the first rotating disk, it runs parallel to the wire and passes through the sleeve and the twisting block simultaneously. After the wires merge, they are pressed against the outer surface of the tensioning wheel on the connecting block. The wires enter the inside of the first wire groove on the first pressure block and travel in a straight line along the wire groove. The wires enter the clamping gap between the first and second pressure wheels. The wires pass through the center hole of the second guide ring on the fixed block. The wires enter the second wire groove on the second pressure block and are clamped and limited by the pressure plate. After the wires are guided against the second tensioning wheel, they are finally fixed on the take-up drum, completing the threading of the entire line.
[0014] In a preferred embodiment, the top plate is also provided with a sliding groove, and the shelf is also provided with a protrusion. The inner sidewall of the sliding groove is in close contact with the outer sidewall of the protrusion. The top plate is also provided with a cylinder three. The output end of the cylinder three is connected to the shelf through a piston rod. The bottom of the shelf is also provided with a rotary motor one. The rotary motor one is connected to a rotating disk one through a connecting rod.
[0015] In a preferred embodiment, the bottom of the slider is provided with a monitoring mechanism, which includes a fixed block, a CCD wire diameter measuring sensor on the fixed block, and a guide ring II on the fixed block.
[0016] Compared with the prior art, the present invention has at least one of the following technical effects:
[0017] 1. This invention utilizes a structural design in which rotating disc one and rotating disc two of the twisting mechanism are coaxially locked and rotate synchronously, and with the stable guidance of lead coil one, the twisted wire is spirally wound around the outer wall of the wire along a constant trajectory, resulting in uniform twisting density and high consistency. At the same time, with the cylinder three driving the placement plate for coaxial positioning, this invention solves the problems of loose strands, eccentricity, uneven winding, and missing twists that are common in traditional twisting machines, thereby improving twisting quality and finished product qualification rate.
[0018] 2. This invention employs a dual detection system combining a visual sensor and a CCD wire diameter measurement sensor. It can monitor cable appearance, routing position, winding uniformity, outer diameter, roundness, bulges, loose strands, and eccentricity defects in real time. This achieves non-contact, high-precision, and fully enclosed online detection without damaging the silicone layer. Detection data is uploaded in real time, and abnormalities trigger automatic alarms or shutdowns, enabling closed-loop quality control throughout the production process and reducing manual inspection intensity and missed detection rates. Furthermore, based on the dual monitoring signals, the external control system can automatically adjust the rotation speed of the first rotary motor, the wire tension of the first unwinding drum, the clamping distance between the first and second pressure rollers, the pressure of the pressure plate, the take-up speed, and the center position of the twisting mechanism. This achieves integrated automatic control of detection, feedback, adjustment, and finishing, automatically correcting defects such as wire diameter deviation, eccentricity, and uneven tension, stabilizing wire diameter and roundness, improving product consistency, and reducing the difficulty and labor intensity of manual operation.
[0019] 3. This invention employs a three-stage shaping structure consisting of initial positioning of the stranded block, adaptive pressing by pressure rollers one and two, and secondary shaping by the pressure plate. Combined with an elastic pressing design, this structure can not only tightly press the stranded wires onto the outer wall of the wire to prevent springback and unwinding, but also avoid excessive compression that could damage the silicone insulation layer. This results in a finished cable with a smooth surface, high roundness, and stable structure, thereby improving the appearance quality and service life of the cable.
[0020] 4. The rotating disk of this invention adopts positioning pins and hand-tightening screws for locking, and is equipped with a handle for quick disassembly, assembly, wire replacement, and maintenance; the overall wire pulling path is clear, with guide grooves and guide rings, making wire threading convenient and less prone to jamming; each motor and cylinder adopts modular control, making debugging simple and improving equipment changeover efficiency and daily maintenance convenience.
[0021] 5. This invention automates the entire process from unwinding, twisting, pressing, monitoring, trimming to winding. With stable unwinding and winding tension control and continuous operation, the equipment runs smoothly with a low failure rate and can work continuously for a long time, improving production efficiency, reducing production costs, and making it suitable for industrial mass production.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0036] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.
[0037] This embodiment provides a silicone wire twisting machine, including a support 1, a top plate 2 on the support 1, and a twisting mechanism on the top plate 2; the twisting mechanism includes a placement plate 3, a rotating disk 5 on the placement plate 3, an arc groove 6 and a threaded hole 13 on the rotating disk 5, a limiting post 8 at the bottom of the rotating disk 5, a lead coil 7 at the top of the rotating disk 5, a second rotating disk 9 on the rotating disk 5, a reserved opening 10 and a threaded hole 14 on the second rotating disk 9, and a wire feeding drum 11 on the rotating disk 9.
[0038] See Figure 1In this embodiment, before the operation begins, the entire machine is connected to an external industrial power supply and compressed air source. All components are checked for secure connections, looseness, and proper lubrication. All motors, cylinders, and sensors are reset to their initial standby state. Then, the cylinder 56 fixedly mounted on the top plate 2 is activated. The cylinder 56 is controlled by an external control system. The cylinder 56 drives the placement plate 3 to move via a piston rod. The protrusion 55 fixedly connected to the bottom of the placement plate 3 forms a precise sliding fit with the sliding groove 54 on the top plate 2. The outer wall of the protrusion 55 and the inner wall of the sliding groove 54 fit tightly with uniform gaps, ensuring that the placement plate 3 moves smoothly without shaking, tilting, or jamming. This ensures the placement plate 3 moves smoothly without deviation, completing the coaxial positioning of the twisting mechanism with the subsequent pressure adjustment mechanism and tensioning mechanism, adapting to the twisting requirements of wires of different diameters.
[0039] Simultaneously, the reserved opening 10 at the bottom of rotating disk 2 9 is aligned and fully engaged with the limiting post 8 fixed at the bottom of rotating disk 1 5, forming a circumferential limiting, radial positioning, and axial support relationship between rotating disk 1 5 and rotating disk 2 9. This ensures that the two disks do not experience relative displacement, wobbling, or significant misalignment during high-speed rotation. Then, the hand-tightening screws 15 are sequentially screwed into the threaded holes 13 on rotating disk 1 5 and 14 on rotating disk 2 9 until tightened, achieving a secure lock between the two disks and preventing loosening during rotation. A handle 12 is fixedly installed on rotating disk 2 9, allowing operators to easily lift, install, disassemble, or finely adjust the angle of rotating disk 2 9, significantly improving the convenience and efficiency of assembly, line replacement, and maintenance.
[0040] See Figure 1-7 Before starting the operation, complete the cable routing according to the preset fixed path. The specific steps are as follows:
[0041] Step 1: Smoothly pull the wire to be processed from the wire reel 2 18, and let it pass through the internal channel of the sleeve 23 on the stranding block 22 and the center hole of the stranding block 22 in sequence;
[0042] Step 2: Pull out the stranded wire from the wire reel 11. After being guided and positioned by the lead coil 7 on the rotating disk 5, the stranded wire runs parallel to the wire and passes through the sleeve 23 and the stranding block 22 simultaneously.
[0043] Step 3: After the cables converge, press them upwards against the outer surface of the tension wheel 25 on the connecting block 21;
[0044] Step 4: The cable enters the wire groove 27 on the pressure block 26 and travels in a straight line along the wire groove 27;
[0045] Step 5: The cable enters the clamping gap between pressure roller 38 and pressure roller 41;
[0046] Step 6: Pass the cable through the center hole of the guide ring 44 on the fixing block 42;
[0047] Step 7: The cable enters the wire groove 47 on the pressure block 46 and is pressed and limited by the pressure plate 48;
[0048] Step 8: After the cable is guided by tensioning wheel 49, it is finally fixed on the take-up drum 51, completing the entire cable threading process.
[0049] Specifically, the wire is pulled out from the second wire reel 18, passes through the sleeve 23 and the stranding block 22, and at the same time, the stranded wire is pulled out from the first wire reel 11, passes through the first lead coil 7 and is wound around the wire, and passes through the sleeve 23 and the stranding block 22. Then the wire and stranded wire are attached to the first tensioning wheel 25, and then the wire and stranded wire are attached to the first conductor groove 27 of the first pressure block 26. After that, the wire and stranded wire pass between the first pressure wheel 38 and the second pressure wheel 41, and then pass through the second guide ring 44. Then the wire and stranded wire are attached to the second conductor groove 47 and the pressure plate 48 on the second pressure block 46. Finally, the wire and stranded wire are attached to the second tensioning wheel 49 and then wound up by the take-up reel 51.
[0050] The rotating disc 29 is equipped with a handle 12;
[0051] The outer wall of the limiting post 8 is in close contact with the inner wall of the reserved opening 10;
[0052] A hand-tightening screw 15 is provided between threaded hole 13 and threaded hole 14.
[0053] A side plate 16 is connected to the top plate 2, a connecting plate 17 is connected to the side plate 16, a wire feeding drum 18 is provided on the connecting plate 17, a rotary motor 19 is provided at the other end of the top plate 2, a coupling 20 is connected to the output end of the rotary motor 19, and the wire feeding drum 18 is connected to the coupling 20.
[0054] The top plate 2 is also provided with a twisting block 22, and the twisting block 22 is provided with a sleeve 23.
[0055] For details, see Figure 1The rotary motor 19, fixedly installed on the top plate 2, is started. The output end of the rotary motor 19 is connected to the coupling 20. The coupling 20 drives the wire feeding drum 18 to rotate at a uniform and stable speed through the linkage transmission, realizing continuous and constant tension wire feeding. The feeding speed can be preset and adjusted by the external control system according to the production rhythm to avoid slack due to feeding too fast or breakage due to feeding too slow. The wire passes through the sleeve 23 on the stranding block 22 and inside the stranding block 22 in sequence, completing the initial orientation of the wire and preventing the wire from deviating. The wire feeding drum 11, which is installed on the rotary disk 9, is used to pull out the stranded wire and pass it through the lead coil 7 on the rotary disk 5. After being guided by the lead coil 7, the stranded wire merges with the wire and passes through the sleeve 23 and the stranding block 22 simultaneously, realizing the merging and positioning of the wire and the stranded wire, preparing for subsequent twisting. The stranded wire is installed and fixed in the unwinding drum 11 on the rotating disk 29, and can rotate freely to achieve passive unwinding. After the stranded wire passes through the lead coil 17, it enters the twisting station in a parallel state with the wire. The lead coil 17 limits, guides and prevents the stranded wire from tangling, ensuring that the stranded wire enters the twisting path in a stable posture. The rotary motor 4, fixedly installed at the bottom of the storage plate 3, is activated. The rotary motor 4 drives the rotary disk 5 to rotate through the linkage transmission. Under the locking action of the limit post 8 and the hand screw 15, the rotary disk 5 drives the rotary disk 9, the unwinding drum 11, and the lead coil 7 to rotate synchronously. The lead coil 7 carries the stranded wire and rotates continuously 360° around the wire. With the axial traction force of the take-up drum 51, the stranded wire is evenly, tightly, and continuously spirally wound around the outer wall of the wire to form a stable twisting structure and complete the core twisting process. The arc-shaped groove 6 opened on the rotary disk 5 reduces the overall weight of the rotary disk, reduces the moment of inertia, reduces the motor load, and improves the rotational stability. On the other hand, it provides movement avoidance space for the lead coil 7, avoids movement interference, ensures smooth, even, and jam-free winding of the stranded wire, and improves the twisting consistency.
[0056] The second wire reel 18 is connected to the first coupling 20 via a connecting rod (not shown).
[0057] The top plate 2 is provided with a connecting block 21, and the connecting block 21 is provided with a tensioning wheel 25;
[0058] A vision sensor 24 is provided at the bottom of the connecting block 21.
[0059] A pressure block 26 is connected to the top plate 2, and a wire groove 27 is opened on the pressure block 26.
[0060] The top plate 2 is also equipped with a pressure regulating mechanism, which includes a baffle 28. A rotary motor 29 is located on the top of the baffle 28. The output end of the rotary motor 29 is connected to a lead screw 30. A lead screw nut 33 is located on the lead screw 30. A slider 32 is located on the lead screw nut 33. The baffle 28 is also equipped with a slide rail 31. The slider 32 slides on the slide rail 31. A cylinder 34 is located on the slider 32. The output end of the cylinder 34 is connected to a limit plate 35 via a piston rod. A limit plate 36 is connected to the limit plate 35. A limit plate 37 is connected to the limit plate 36. A pressure roller 38 is located on the limit plate 37. A limit block 39 is also located on the slider 32. A limit plate 40 is connected to the limit block 39. A pressure roller 41 is located on the limit plate 40.
[0061] For details, see Figure 3 The rotary motor 29, which is fixedly installed on the top of the baffle 28, is activated. The output end of the rotary motor 29 drives the lead screw 30 to rotate at a constant speed. The lead screw 30 and the lead screw nut 33 form a precision thread transmission pair, which drives the slider 32 to move smoothly up and down along the slide rail 31 fixed on the baffle 28. This enables continuous, precise, and stepless adjustment of the working height of the pressing mechanism. It can be adapted to the processing of cables with different wire diameters and different layers of twisting. It has high adjustment accuracy and a wide range of applications.
[0062] The cylinder 34 fixedly mounted on the starter slider 32 extends its piston rod, driving the limit plate 35 to move. This moves the limit plate 36, limit plate 37, and pressure roller 38 toward the cable in sequence. The pressure roller 38 and the pressure roller 41 of the limit plate 40 on the limit block 39 cooperate to form an adaptive elastic pressing structure. This structure applies a uniform and moderate pressing force to the twisted cable, tightly pressing and shaping the stranded wire wrapped around the wire, eliminating gaps between the stranded wire and the wire, preventing the stranded wire from loosening, springing back, or untangling, and ensuring a firm and stable twisted structure.
[0063] The top plate 2 is also provided with a tensioning mechanism, which includes a second cylinder 45. The output end of the second cylinder 45 is connected to a second pressure block 46 through a piston rod. The second pressure block 46 is provided with a wire groove 47.
[0064] A pressure plate 48 is connected to the pressure block 46.
[0065] Further, see Figure 1The cylinder 45 on the top plate 2 is activated. The cylinder 45 drives the pressure block 46 to move through the piston rod. The twisted cable enters the conductor groove 47 on the pressure block 46. The pressure plate 48 fixed on the pressure block 46 cooperates with the conductor groove 47 to perform secondary pressing, shaping and straightening of the cable. This further eliminates the twisting gap, corrects the roundness of the cable, corrects the eccentricity, and smooths the surface unevenness, so that the twisted wire and the wire are tightly combined into a whole. Finally, a finished cable with a round appearance, uniform size and stable structure is formed, which significantly improves the appearance quality and structural strength of the finished cable.
[0066] In this embodiment, the stranded wire includes, but is not limited to, silicone wire, tinned copper stranded wire, bare copper stranded wire, fiber-reinforced stranded wire, and insulated core wire.
[0067] One end of the top plate 2 is provided with a tensioning wheel 49 and a connecting plate 50, and the connecting plate 50 is provided with a take-up drum 51.
[0068] The other end of the top plate 2 is equipped with a rotary motor 4 52, the output end of the rotary motor 4 52 is connected to a coupling 2 53, and a winding drum 51 is connected to the coupling 2 53.
[0069] Further, see Figure 1 After being shaped, the cable adheres tightly to the tensioning wheel 49 on the top plate 2, completing the final tensioning and guiding, ensuring that the cable maintains constant tension, travels smoothly, and does not shake or twist before entering the winding stage. The rotary motor 52 is started, and the output end of the rotary motor 52 is driven by the connecting rod through the coupling 53 to drive the winding drum 51 on the connecting plate 50 to rotate at a uniform and stable speed, neatly, tightly, and orderly winding up the twisted, pressed, and shaped finished wire. This achieves continuous and automated processing throughout the entire process. The winding tension can be automatically adjusted by the control system to avoid messiness caused by excessively loose winding or stretching deformation caused by excessively tight winding.
[0070] The twisted cable is pulled by the traction force of the take-up drum 51 and pressed against the tensioning wheel 25 on the connecting block 21. The tensioning wheel 25 provides initial tension to the twisted cable, eliminating cable slack and untwisted strands, and ensuring stable twisting. A vision sensor 24 is fixedly installed at the bottom of the connecting block 21. The lens of the vision sensor 24 is pointed towards the cable travel path and collects image information such as the cable's routing position, twisting uniformity, surface appearance, whether there are untwisted strands, whether there are missing twists, and whether there is deviation in real time. The image signal is then transmitted to the external control system in real time.
[0071] The external control system analyzes and processes image information. When it detects abnormalities such as thread deviation, uneven winding, loose strands, missing twists, or appearance defects, it immediately outputs control signals, triggers audible and visual warnings, or directly controls the entire machine to stop, preventing defective products from flowing into the next process and effectively improving product qualification rate and production stability.
[0072] After tensioning and preliminary monitoring, the cable enters the conductor groove 27 of the pressure block 26. The conductor groove 27 is an arc-shaped or U-shaped limiting groove that matches the outer diameter of the cable. It guides the cable in a straight line, constrains it radially, prevents twisting and swinging, and ensures that the cable enters the subsequent pressing process in a stable and straight posture. This avoids radial jump, lateral displacement, and twisting during the pressing process, and ensures accurate pressing position and consistent pressing effect.
[0073] The take-up drum 51 is connected to the coupling 53 via a connecting rod (not shown).
[0074] The top plate 2 is also provided with a sliding groove 54, and the shelf 3 is also provided with a protrusion 55. The inner side wall of the sliding groove 54 and the outer side wall of the protrusion 55 are in close contact.
[0075] The top plate 2 is also equipped with a cylinder 3 56. The output end of the cylinder 3 56 is connected to the shelf 3 via a piston rod. The bottom of the shelf 3 is also equipped with a rotary motor 4. The rotary motor 4 is connected to a rotating disk 5 via a connecting rod.
[0076] The bottom of the slider 32 is provided with a monitoring mechanism, which includes a fixed block 42, a CCD wire diameter measuring sensor 43 on the fixed block 42, and a guide ring 44 on the fixed block 42.
[0077] Further, see Figure 3 The CCD wire diameter measurement sensor 43 on the fixed block 42 is arranged around the guide ring 44 to form a fully enclosed non-contact optical measurement structure. It does not directly contact the cable surface, does not scratch the stranded wire, and does not affect the cable's movement. The CCD wire diameter measurement sensor 43 adopts non-contact optical measurement to collect key dimensions and appearance parameters of the twisted cable in real time, such as the outer diameter, cross-sectional roundness, strand winding tightness, whether there is a bulge, whether there is a loose strand, whether there is a missing twist, whether there is eccentricity, and whether there is an ellipse. The data is transmitted to the external control system in real time, continuously, and with high precision.
[0078] When defects such as wire diameter exceeding preset tolerance, excessive roundness, excessive eccentricity, bulges, loose strands, or missing twists are detected, the control system immediately issues an alarm signal and can control the equipment to stop, achieving full online quality control and ensuring a high degree of consistency between the dimensional accuracy and appearance quality of the finished cable. Guide ring 2 (44) provides secondary guidance for the compressed cable, ensuring its smooth entry into the next process and improving compression accuracy and stability.
[0079] Furthermore, when the visual sensor 24 detects cable misalignment, loose strands, uneven winding, or appearance defects, or when the CCD wire diameter measurement sensor 43 detects excessive wire diameter, poor roundness, eccentricity, bulges, loose strands, or missing twists, the external control system immediately and automatically performs multi-dimensional coordinated adjustment and repair according to preset programs and parameter thresholds.
[0080] The visual sensor 24 and the CCD wire diameter measurement sensor 43 form a dual online monitoring system, both of which are connected to the external control system. The rotation speed of the rotary motor 4 is adjusted to change the wire tension of the unwinding drum 11 to correct the strand tightness, twisting speed and winding density. The rotary motor 329 is driven to move the lead screw 30, adjusting the clamping distance between the pressure roller 38 and the pressure roller 41. The cylinder 45 is driven to move, adjusting the tension and contact distance of the pressure plate 48. The take-up drum 51 is adjusted to stabilize the overall tension.
[0081] The drive cylinder 356 moves the placement plate 3, fine-tuning the relative position and center distance between the twisting mechanism and the cable. Through a fully closed-loop intelligent control system of real-time detection, rapid feedback, precise adjustment, and online trimming, this device can automatically correct various defects in the twisting process, ensuring that the finished cable has a uniform outer diameter, high roundness, tight winding, no eccentricity, no loose strands, no bulges, and no missing twists. This significantly improves product consistency, processing stability, and production qualification rate, while reducing manual intervention and defect rate.
[0082] In this embodiment, rotating disk 5 and rotating disk 9 are made of hard aluminum alloy or engineering plastic POM, which are lightweight and have low rotational inertia, thus reducing the load on rotating motor 4 and improving rotational stability. Lead coil 7, guide coil 44, and sleeve 23 are made of polytetrafluoroethylene (PTFE), nylon PA66, or polyurethane (PU), with smooth surfaces and low coefficients of friction, preventing scratches on silicone wires and stranded wires and ensuring smooth cable routing. Pressure roller 38, pressure roller 41, tension roller 25, and tension roller 49 are made of polyurethane elastomer (PU) or nitrile rubber (NBR) coated with a metal core, providing moderate elasticity, preventing damage to the cable surface, and ensuring stable and reliable pressing and tensioning processes. Stranding block 22 and pressure plate 48 are made of brass or stainless steel, with smooth, wear-resistant surfaces that do not scratch the cable, ensuring the quality of twisting and shaping.
[0083] In this embodiment, the external control system adopts any one of a programmable logic controller (PLC), a microcontroller, or an embedded microprocessor. The external control system is electrically connected to rotary motor 4, rotary motor 19, rotary motor 29, rotary motor 42, cylinder 34, cylinder 45, cylinder 36, vision sensor 24, and CCD wire diameter measurement sensor 43, respectively. It is used to receive signals collected by the sensors and control the start, stop, speed, and stroke of each motor and cylinder to realize the automatic control and abnormal protection of the whole machine.
[0084] Specifically, this embodiment employs an external control system to achieve fully automatic centralized control. The external control system utilizes any one of a programmable logic controller (PLC), a microcontroller, or an embedded microprocessor, possessing functions such as signal acquisition, logic operation, parameter storage, output control, abnormal alarm, and automatic correction. The control system is electrically connected to rotating motor 4, rotating motor 19, rotating motor 29, rotating motor 42, cylinder 34, cylinder 45, cylinder 36, vision sensor 24, and CCD wire diameter measurement sensor 43, forming a complete electrical control loop.
[0085] This embodiment features an integrated design that integrates revolution-type twisting, adaptive clamping, multi-stage tensioning and shaping, dual monitoring by vision + CCD wire diameter measurement sensors, fully closed-loop automatic trimming, and automated winding and unwinding. It is applicable to the twisting processing of wires and similar cables of various materials and specifications.
