Description
Technical Field
[0001] This invention relates to the field of stranding machine technology, and more particularly to a twisted pair stranding machine. Background Technology
[0002] Stranding machines are the "weavers" of modern industry. Through precise mechanical motion, they transform thin, discrete single wires into various powerful and structurally stable cable products, providing fundamental connections for power transmission, information communication, and various electrical equipment. From the charging cables of your mobile phone to the cables of cross-sea bridges, stranding technology has played a crucial role. When selecting a stranding machine, the most suitable type needs to be determined based on the material (bare wire / insulated wire), specifications (thickness, number of strands), target product performance (such as strand pitch requirements), and production capacity needs.
[0003] First, multiple single wires are threaded through the wire feeding reel, guide rollers, and winding die of the stranding cage as required, and correctly fixed on the take-up reel. This step ensures a smooth wire path and an accurate starting point, laying the foundation for stable operation later. Upon startup, the stranding machine's operation begins with the traction machine and the main stranding cage precisely synchronizing their start and stop at a preset speed ratio, ensuring uniform and consistent strand pitch from the source. During this process, their speeds are linked and locked in real-time through an electronic gear system, keeping the strand pitch constant during high-speed operation. Finally, the take-up machine employs constant torque control, providing gentle and continuous tension, ensuring even stress and neat coil shape during winding, thereby comprehensively improving the structural consistency and quality of the stranded wire.
[0004] During normal operation of a stranding machine, multiple strands are simultaneously unloaded and twisted. During this process, due to unstable tension control or mechanical vibration, it is inevitable that one or more strands may loosen during the pulling process. This loosening causes the strand pitch (i.e., the axial length of one revolution of the strand) to suddenly increase, disrupting the originally tight and uniform stranding structure.
[0005] The problem of excessively large strand pitch during the pulling process of stranded wire not only directly damages the physical structure and electrical performance of the product, causing the entire stranded wire to become a defective or scrap product, seriously affecting the final quality; at the same time, under the complex working conditions of multiple wires operating at high speed, such loosening faults in single or multiple strands are extremely difficult to identify quickly and accurately. This defect of "difficult to detect and difficult to locate" often forces production into tedious downtime for troubleshooting, which not only significantly reduces production efficiency but also causes serious waste of raw materials and a significant increase in production costs.
[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing twisted-pair stranding machines. Summary of the Invention
[0007] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. An embodiment of the present invention provides a twisted-pair stranding machine to solve the technical problem of difficulty in detecting and locating loosening of single or multiple strands during the use of existing twisted-pair stranding machines.
[0008] The present invention adopts the following technical solution: a twisted pair stranding machine, including a winding machine, a protective housing disposed on the side of the winding machine, a stranding rotation structure disposed inside the protective housing, and two first drive motors, and further including... A detection component with identification function installed inside the twisting and rotating structure; The detection component includes a guide groove with adjustable position and angle, a movable component located inside the guide groove, and a wire support rod that can move up and down. When the threading support rod rises, the moving component moves vertically upwards to the top of the guide groove; When the threading support rod falls, the moving component moves forward and downward to its initial position inside the guide groove.

The power-off component includes a first energizing plate disposed inside the guide groove, a second energizing plate disposed on both sides of the outer wall of the movable component, and a retractable power-off clutch component. When the wire support rod rises, the first and second power boards remain de-energized. When the wire support rod falls, the first and second power boards are first de-energized, then energized, and finally de-energized. When the power is off, the clutch components are in a closed state; When energized, the clutch components are in a disengaged state.
[0009] Preferably, the detection assembly further includes multiple second storage boxes, and the hinged rotating structure has multiple second storage boxes inside, with the guide grooves located on both sides of the inner wall of the second storage boxes; The guide groove is D-shaped and consists of a vertical groove and an arc-shaped groove. The moving component moves sequentially from the bottom of the vertical groove to the top of the vertical groove, and then from the top of the vertical groove through the arc groove to the bottom of the vertical groove.
[0010] Preferably, the twisting and rotating structure includes a wire distributor, a first storage box for storing multiple second storage boxes, and a support base. The outer wall of the wire distributor is connected to the support base via a bearing. The support base is installed inside the protective housing.

[0014] Preferably, the moving component includes a first sliding block, a connecting plate, and a slide groove disposed inside the guide groove. The second storage box is provided with a connecting plate inside. The first sliding blocks are installed on both sides of the connecting plate. A slide groove is installed in the middle of the connecting plate. A second sliding block is provided inside the slide groove. The upper part of the second sliding block is fixedly connected to the bottom of the wire threading support rod. When the threading support rod rises: the threading support rod and the second sliding block connected to the threading support rod remain in the same position inside the groove; When the threading support rod falls: the position of the threading support rod remains unchanged, and the second sliding block connected to the threading support rod is inside the other end of the slide groove.
[0015] Preferably, the first energizing plate is disposed on both sides of the middle position of the arc-shaped groove, and the second energizing plate is installed on the outer wall of the first slider.
[0016] Preferably, the clutch assembly includes a drive block, a driven block, and a storage cylinder. The storage cylinder is installed in the middle of the side of the distributor plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This equipment innovatively introduces a multi-wire automatic identification and detection component based on tension sensing. Through the linkage between the threading support rod and the moving component, the slack of the stranded wire can be accurately identified. When abnormal slack is detected, the power-off component is automatically triggered to cut off the power, effectively avoiding problems such as uneven strand pitch and reduced product quality caused by strand slack, and significantly improving the production yield.
[0019] 2. Highly efficient clutch power-off mechanism: The clutch assembly design driven by a pole enables rapid separation and engagement of power transmission. In the event of a fault, it can instantly cut off the power to the stranding mechanism without affecting the pre-tensioning force of the winding machine on the wire harness. This protects equipment safety, greatly facilitates manual maintenance, and significantly shortens fault handling time.
[0020] 3. Stable guiding and resetting structure: The guide groove adopts a D-shaped design combining vertical and arc-shaped grooves, along with a baffle assembly with a sloping surface, ensuring precise and smooth trajectory of the moving component during ascent and descent. This mechanical limiting and guiding design is not only simple and reliable in structure, but also effectively prevents jamming or derailment of the component during high-speed operation.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0025] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
[0026] 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.
[0027] The following is combined Figures 1 to 14 As shown, this embodiment of the invention provides a twisted pair stranding machine, including a winding machine 1, a protective housing 2 disposed on the side of the winding machine 1, a stranding rotation structure 3 disposed inside the protective housing 2, and two first drive motors 10, and also includes... A detection component 4 with identification function is installed inside the twisting and rotating structure 3; The detection component 4 includes a guide groove 42 with an adjustable position angle, a movable component 5 located inside the guide groove 42, and a wire support rod 62 that can move up and down. When the threading support rod 62 rises, the moving component 5 moves vertically upward to the top of the guide groove 42; When the threading support rod 62 falls, the moving component 5 moves forward and downward to the initial position inside the guide groove 42. Power-off components are installed between the side of the winding machine 1 and the first drive motor 10, and between the side of the twisting and rotating structure 3 and the first drive motor 10. The power-off assembly includes a first energizing plate 71 disposed inside the guide groove 42, a second energizing plate 77 disposed on both sides of the outer wall of the movable assembly 5, and a retractable power-off clutch assembly. When the wire support rod 62 rises, the first energized plate 71 and the second energized plate 77 remain de-energized. When the wire support rod 62 falls, the first energized plate 71 and the second energized plate 77 first remain in the de-energized state, then in the energized state, and finally in the de-energized state. When the power is off, the clutch components are in a closed state; When energized, the clutch components are in a disengaged state.
[0028] The detection component 4 also includes multiple second storage boxes 41. The inside of the hinged rotating structure 3 is provided with multiple second storage boxes 41, and the guide grooves 42 are provided on both sides of the inner wall of the second storage boxes 41. The guide groove 42 is D-shaped and consists of a vertical groove and an arc-shaped groove. The moving component 5 moves sequentially from the bottom of the vertical groove to the top of the vertical groove, and then from the top of the vertical groove through the arc groove to the bottom of the vertical groove.
[0029] As an optional embodiment, by using the pre-set resistance of the baffle 83 and the graded stroke design of the D-shaped guide groove 42, the false triggering caused by the centrifugal force of the equipment rotation and the tension fluctuation during normal production is filtered out. Only when the loose line truly reaches the unqualified level will the machine be stopped, thus reducing the false triggering rate.
[0030] The twisting and rotating structure 3 includes a wire distribution plate 34, a first storage box 33 for storing multiple second storage boxes 41, and a support base 31. The outer wall of the wire distribution plate 34 is connected to the support base 31 through a bearing. The support base 31 is installed inside the protective shell 2. Multiple wire coil fixing brackets 32 are installed on the side of the wire distribution plate 34, and the first storage box 33 is installed on the side of the wire distribution plate 34. The second storage box 41 is provided with a positioning sleeve 64 inside, and a first spring 65 is provided on the outside of the positioning sleeve 64. A wire support rod 62 is provided on the inside of the positioning sleeve 64. The top of the positioning sleeve 64 and the top of the first spring 65 are fixedly connected to the inner wall of the second storage box 41.
[0031] A wire-splitting die 9 is installed on the side of the winding machine 1. The middle position of the wire-splitting die 9, the middle position of the wire-splitting disc 34, and the middle position of the first storage box 33 are on the same horizontal line.
[0032] As an optional embodiment, the first storage box 33 is circular, and a plurality of second storage boxes 41 are distributed equidistantly around the center of the first storage box 33.
[0033] The threading support rod 62 and the positioning sleeve 64 are slidably connected. Multiple wire coil fixing frames 32 are distributed in an equidistant circle with the center of the wire distribution disc 34 as the center. Each stranded wire corresponds to an independent detection unit. After the machine stops, the loose stranded wire can be located directly according to the detection unit of the action, without the need to check each wire one by one. The fault handling time is shortened and the downtime loss is reduced.
[0034] As an optional embodiment, the multi-strand strands are respectively fixed on the coil fixing frame 32, and pass through the guide holes of the splitter 34 and the threading holes of the threading support rod 62, and finally twisted by the paralleling die 9 and wound on the winding machine 1 (e.g. Figure 2 and Figure 4 (as shown) When the stranded wire is taut, the tension causes the wire threading support rod 62 to move upward against the elastic force of the first spring 65, driving the moving component 5 to rise to the highest point along the vertical groove of the guide groove 42 (e.g., Figure 3 and Figure 5 (As shown).
[0035] The moving component 5 includes a first sliding block 51, a connecting plate 52, and a slide groove 53 disposed inside the guide groove 42. The second storage box 41 is provided with a connecting plate 52 inside. The first sliding blocks 51 are installed on both sides of the connecting plate 52. The slide groove 53 is installed in the middle of the connecting plate 52. The slide groove 53 is provided with a second sliding block 61 inside. The top of the second sliding block 61 is fixedly connected to the bottom of the wire threading support rod 62. When the threading support rod 62 rises: the threading support rod 62 and the second sliding block 61 connected to the threading support rod 62 remain in the same position inside the slide groove 53; When the threading support rod 62 falls: the position of the threading support rod 62 remains unchanged, and the second sliding block 61 connected to the threading support rod 62 is at the other end inside the slide groove 53.
[0036] The first energizing plate 71 is disposed on both sides of the middle position of the arc groove, and the second energizing plate 77 is installed on the outer wall of the first slider.
[0037] The clutch assembly includes a drive block 76, a driven block 75, and a storage cylinder 72. The storage cylinder 72 is installed in the middle of the side of the distributor 34. An electric rod 73 is installed inside the storage cylinder 72. The side of the electric rod 73 passes through the storage cylinder 72 and is connected to the driven block 75. The drive block 76 is provided inside the driven block 75. The side of the drive block 76 is connected to the output end of the drive motor 10. A motor is installed in the middle of the first storage box 33. Multiple first energized boards 71 are electrically connected to pole 73 via conductive slip rings, and multiple second energized boards 77 are electrically connected to motor via conductive slip rings. The conductive slip ring design prevents wires from tangling and ensures long-term stable operation. When the first energizing plate 71 and the second energizing plate 77 are not in contact: the pole 73 is not energized, and the driven block 75 and the driving block 76 are in close contact. When the first energized plate 71 comes into contact with the second energized plate 77: the drive rod 73 retracts, and the driven block 75 separates from the drive block 76.
[0038] As an optional embodiment, when one or more strands become loose during the stranding process, the tension of the wire harness decreases. If the degree of looseness is within the allowable range, the first sliding block 51 slides downward along the arc-shaped groove of the guide groove 42 under the action of gravity and spring, and uses the ramp design above the baffle 83 to allow it to pass smoothly. At this time, the first energized plate 71 and the second energized plate 77 remain separated and de-energized, and the equipment continues to operate. This graded response mechanism avoids frequent downtime caused by minor tension fluctuations, greatly improving production continuity. If the stranded wire slack exceeds the set threshold, the threading support rod 62 falls further, causing the moving component 5 to continue sliding down until the first energized plate 71 contacts the second energized plate 77 and energizes the circuit. At this time, the current triggers the electric rod 73 in the power-off component to retract through the conductive slip ring, causing the driven block 75 to retract and separate from the driving block 76 (e.g., Figure 12 and Figure 9 (As shown). Since the drive block 76 is connected to the drive motor 10, the disengagement of the clutch assembly directly cuts off the power transmission, forcing the twisted rotating structure 3 to stop rotating immediately, while the slack strand remains taut (as shown). Figure 6 (as shown) This intelligent automatic shutdown protection mechanism can respond to anomalies within milliseconds, avoiding uneven strand pitch and product quality degradation caused by loose strands. It also greatly facilitates operators in quickly locating and adjusting loose strands, significantly shortening fault handling time. After the fault is cleared and tension is restored, the threading support rod 62 resets and rises, the pole 73 is de-energized and resets, the clutch assembly re-engages, and the equipment quickly resumes normal operation, thus comprehensively ensuring the overall stability and yield rate of cable production. A blocking assembly 8 is provided above the outer side of the vertical groove. The blocking assembly 8 includes a baffle 83 that moves left and right, a fixing groove 81 for storing the baffle 83, and a second spring 82 for returning the baffle 83 to its original position. The fixing groove 81 is located above the outside of the vertical groove, and the second spring 82 is installed inside the fixing groove 81. The side of the second spring 82 is connected to the baffle 83. The baffle 83 and the fixing groove 81 are slidably connected, and both the upper and lower sides of the baffle 83 are sloped.
[0039] As an optional embodiment, during normal twisting and winding, the tension of the wire harness pulls the threading support rod 62 to overcome the resistance of the first spring 65 and slide upward on the inner wall of the positioning sleeve 64. The threading support rod 62 drives the second sliding block 61 and the connecting plate 52, thereby driving the first sliding block 51 to slide smoothly upward along the vertical groove of the guide groove 42 (e.g., Figure 5 As shown and Figure 10 ); When the first sliding block 51 reaches the top of the vertical groove, the slope design on the lower side of the baffle 83 compresses the second spring 82 under the pulling force, causing the baffle 83 to retract into the fixed groove 81 (as shown). Figure 7 (As shown); after the first sliding block 51 passes the baffle 83, the baffle 83 is reset under the action of the spring (as shown). Figure 8 (as shown) This ingenious design, combining ramps and springs, not only ensures the precise trajectory of the moving component 5 during high-speed operation but also effectively prevents the component from jamming or derailing, ensuring extremely high stability of the equipment during normal production.
[0040] Working principle: After the equipment is started, the two drive motors 10 operate synchronously, driving the stranding rotating structure 3 to twist the wire and the winding machine 1 to wind it up. The tension of the wire harness pulls the wire threading support rod 62 to overcome the resistance of the first spring 65 and move it upward, driving the moving component 5 to rise along the vertical groove of the guide groove 42 and pass over the baffle 83. At this time, the first energized plate 71 separates from the second energized plate 77, the driven block 75 and the drive block 76 are in contact, and the equipment operates normally.
[0041] Abnormal slack shutdown phase: When the stranded wire becomes severely slack, causing a sudden drop in tension, the threading support rod 62 drives the moving component 5 to slide down the arc-shaped groove of the guide groove 42. The first energizing plate 71 and the second energizing plate 77 come into contact and become energized, triggering the retraction of the electric rod 73. This forces the driven block 75 to separate from the driving block 76, instantly cutting off the power to the stranding rotation structure 3 and stopping it. The winding machine 1 remains taut. After the fault is cleared, the components automatically reset, and the equipment resumes production.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
