Description

Technical Field

[0001] The present invention relates to the field of cable processing, in particular to a wire stranding device for cable production. Background Art

[0002] Cable stranding is a method of manufacturing cables. The stranding process involves twisting multiple thin wires together in a specific direction and pitch (the distance the wire completes one spiral turn during the stranding process) to form a stronger and more flexible conductor. This process not only improves the overall strength and flexibility of the cable, but also increases its conductive properties.

[0003] In the traditional cable twisting process, multiple wires are usually twisted together directly. However, since some wires may have defects on their outer surfaces, these defects are often difficult to detect during the twisting process. As the machine continues to run, the product quality is unqualified, and the locations of the unqualified points cannot be found, resulting in cable waste. This needs to be improved. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a stranding device for cable production, which can detect and mark the position of defects in the conductor, so as to accurately grasp the position of the defective points of the cable in the later stage and reduce cable waste.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a stranding device for cable production includes a base 1, a reel 2, a strander 3, a tightener 4, a reel 5 and a marking mechanism 6.

[0032] like Figure 1 、 Figure 2 As shown, the base 1 is horizontally set on the ground, and the unwinding drum 2 is horizontally connected to the front end position of the base 1. A plurality of unwinding shafts 21 are evenly connected to the unwinding drum 2 so that the wire can be automatically unwound and twisted through the unwinding shafts 21.

[0033] like Figure 1 、 Figure 2As shown, the wire twister 3 includes a support frame 31, a wire twisting drum 32, and a wire twisting barrel 33. The support frame 31 is horizontally positioned at the center of the unwinding drum 2. An eddy current flaw detector 34 is mounted on the support frame 31 for threading the wires. The wire twisting drum 32 is positioned at the end of the support frame 31, with the wires threaded at its edge. The wire twisting barrel 33 is horizontally positioned behind the wire twisting drum 32 and is used to thread multiple strands of wire.

[0034] like Figure 1 、 Figure 3 As shown, the tightener 4 includes a tightening seat 41 and a pair of tightening wheels 42. The tightening seat 41 is vertically arranged on the base 1. The tightening wheels 42 are rotatably connected to both ends of the tightening seat 41. The tightening wheels 42 are provided with tightening grooves 43 for the wire to be inserted. The winding drum 5 is rotatably connected to the rear end of the base 1 and is used to reel the wire.

[0035] like Figure 1 、 Figure 4 As shown, the marking mechanism 6 is disposed between the strander 3 and the tightener 4 and is used to mark the defective locations of the conductor. The marking mechanism 6 includes a column 61 and a labeling machine 62. The column 61 is vertically disposed on the base 1. The labeling machine 62 is vertically slidably connected to the column 61 and is used to attach the marking strip to the outer wall of the conductor.

[0036] like Figure 4 As shown, a semicircular pressure plate 63 is horizontally mounted at the rear of the labeling machine 62 and is used to press against the outer wall of the conductor. The front end of the pressure plate 63 is flared to allow the marker strip to enter the pressure plate 63 smoothly. An electric heating wire 64 is installed inside the front end of the pressure plate 63 to heat the marker strip and ensure that it is stably bonded to the outer wall of the conductor.

[0037] When twisting a cable, the conductors are sequentially passed through the eddy current flaw detector 34 and the outer edge of the stranding drum 32. After being gathered together, they are passed through the stranding drum 33. The multiple strands of conductor are then grasped and the unwinding drum 2 is controlled to rotate, which in turn drives the stranding unit 3 to rotate synchronously, completing the stranding process. The stranded conductors are then wound around a pair of take-up wheels 42 on the collector and secured to the take-up drum 5, completing the stranding and automatic winding process.

[0038] During the stranding process, an eddy current flaw detector 34 detects defects on the outer surface of the wire. If a defect is detected, the eddy current flaw detector 34 transmits the information to the marking mechanism 6. At this point, the labeling mechanism 62 moves downward and contacts the outer surface of the wire. The labeling mechanism 62 then automatically applies a marking strip to the outer surface of the wire, marking the defect location.

[0039] Then the wire drives the identification strip to move backward synchronously. At this time, the wire passes through the position of the pressure plate 63. The identification strip is first heated by the electric heating wire 64 on the pressure plate 63. Then, under the pressing force of the pressure plate 63, the identification strip is firmly adhered to the outer wall of the wire to prevent the identification strip from falling off, and the marking is completed.

[0040] Therefore, by setting an eddy current flaw detector 34 on the stranding device, the wire defects can be automatically detected after the wire is unwound. After the defect is detected, the marking mechanism 6 is used to automatically stick the identification strip on the outer wall of the stranded wire at the defect position, so that the defect position can be found intuitively and accurately in the later stage, and the defect position can be cut off and removed, thereby reducing cable waste.

[0041] like Figure 1 、 Figure 5 As shown, an oiling box 7 for the stranded wire to pass through is provided between the tensioner 4 and the reel 5. Upper guide wheels 71 are provided on both upper side walls of the oiling box 7, and lower guide wheels 72 are provided on the lower side walls. The wire passes over the upper guide wheels 71 and the lower guide wheels 72, and is located in the oiling box 7 in a U shape.

[0042] like Figure 5 As shown, the lower guide wheel 72 is vertically slidably connected to the oil tank 7, and a screw rod 73 is vertically threaded on the oil tank 7. The lower end of the screw rod 73 is rotatably connected to the lower guide wheel 72. A trumpet-shaped scraper 74 is provided at the outlet of the oil tank 7 to scrape off excess grease.

[0043] like Figure 1 、 Figure 6 As shown, an oiling tube 75 is horizontally provided at the rear end of the oiling box 7, and a brush 76 is provided on the inner wall of the oiling tube 75 to abut against the outer wall of the wire. An oiling ring 77 is rotatably connected to the front end of the oiling tube 75, and a ball 78 is provided on the inner wall of the oiling ring 77 to be located between the multiple wires.

[0044] When winding a strand of wire, screw 73 is first controlled to rotate, causing the pair of lower guide wheels 72 to move upward and position above upper guide wheel 71. The strand of wire then passes over the pair of upper guide wheels 71 and through trumpet-shaped scraper 74. Screw 73 is then controlled to rotate in the opposite direction, causing the pair of lower guide wheels 72 to move downward, pressing the strand of wire into a U-shape within oil tank 7 and immersing it in lubricating oil. The strand of wire is then passed through oil ring 77 and oil tube 75, with balls 78 on oil ring 77 positioned within the gaps between the strands.

[0045] As the wire strands pass through the oiling tank 7, they are automatically soaked in lubricating oil. Excess grease is then scraped off by a scraper 74. As the wire strands move, the action of the balls 78 and the wires causes the oiling ring 77 to rotate automatically, pressing the balls 78 against the gaps between the wire strands, effectively applying oil to the gaps. Subsequently, a brush 76 within the oiling tube 75 evenly coats the outer walls of the wire strands, completing the even application of lubricant.

[0046] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
