Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a double-disc vertical untwisting machine. Background Technology

[0002] During the manufacturing process of cables, especially after processes such as stranding, torsional stress inevitably occurs inside. If this torsional stress is not properly handled, it can cause many problems for the subsequent use of the cables. For example, in actual wiring, cables may become twisted, knotted, or tangled. Therefore, cable manufacturers use de-twisting machines to solve the problem of torsional stress in cables. During the laying process, the cable is rotated in the opposite direction, thus forming a reverse pre-twist.

[0003] Currently, existing untwisting machines on the market generally push and twist a single spool, but twisted-pair take-up machines require pushing and twisting both spools, necessitating the placement of two untwisting machines and requiring a larger space. This undoubtedly increases the difficulty and cost of production layout for companies with limited factory space. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a dual-disc vertical untwisting machine, which can simultaneously untwise and untwise both discs to release the wire. It is designed to be used in conjunction with a twisted-pair take-up machine and occupies a small area.

[0005] Therefore, the technical solution of this utility model is: a double-disc vertical untwisting machine, including a frame, with two untwisting stations inside the frame, and an untwisting assembly in each untwisting station; the untwisting assembly includes a vertical rocker arm, the upper and lower ends of which are rotatably mounted on the frame; an I-beam wire pulley and a wire feeding motor for driving the I-beam wire pulley to rotate are installed inside the vertical rocker arm; a drive motor is provided between the two untwisting stations, and the drive motor drives the two vertical rocker arms to rotate simultaneously through a pulley set; an untwisting bow seat is provided at the upper and lower ends of each vertical rocker arm, and two untwisting bows are symmetrically arranged between the two untwisting bow seats; multiple sets of guide components are provided on the inner side of the untwisting bows, each set of guide components including a perforated wire threading seat and a guide auxiliary wheel.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: multiple sets of guide wheels are installed above and below the vertical cradle. The cable end on the I-beam spool passes through the inner side of the torsion bow belt along the upper guide wheel and then passes out from the lower guide wheel.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the cable head passes sequentially through all the perforated cable holders and guide auxiliary wheels on the inner side of the torsion bow.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the vertical rocker arm is provided with a hollow upper rotating shaft and a lower rotating shaft at both ends, the upper rotating shaft is provided with a first guide wheel, and the lower rotating shaft is provided with a second guide wheel; the cable head passes through the upper guide wheel, the upper rotating shaft, the first guide wheel, the torsion belt, the second guide wheel, the lower rotating shaft, and the lower guide wheel in sequence.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: two wire feeding swing arms are rotatably mounted on the side of the frame, and a wire storage wheel is provided at the front end of the wire feeding swing arms. After the wires of the two I-beam wire wheels pass through the lower rotating shaft, they enter the wire storage wheel through multiple third guide wheels.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a first pulley is fixed on the lower rotating shaft, and a second pulley is installed on the output shaft of the drive motor. The second pulley is connected to the first pulley on both sides by two belts.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the vertical cradle is provided with a fixed top head and a movable top head on the left and right sides respectively, which are clamped at the center holes on both sides of the I-beam reel; the fixed top head is connected to the output shaft of the wire feeding motor through a gear set, which drives the I-beam reel to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Two untwisting stations are set up inside the frame, each equipped with an untwisting component, which can realize the simultaneous untwisting and unwinding of the double discs; at the same time, the same drive motor drives the two vertical cradles to rotate simultaneously, ensuring the synchronicity and stability of the rotation of the two vertical cradles, making the double disc untwisting process more coordinated, further ensuring the consistency of the untwisting effect, and also greatly saving space and improving space utilization.

[0014] 2. Multiple sets of perforated cable guides and auxiliary guide wheels are installed on the inner side of the un-twist bow. These, along with the guide wheels at the upper and lower ends of the vertical cradle and the guide wheels within the upper and lower rotating shafts, provide precise, multi-dimensional guidance for the cable. During the un-twist process of the vertical cradle rotation, the cable is stably pre-twisted in the reverse direction, effectively improving the un-twist effect. This allows for a more complete release of internal torsional stress in the cable, reducing the likelihood of twisting, knotting, or tangling during subsequent use, thus improving the cable's quality and performance.

[0015] 3. The cable feeding arm and cable storage wheel are installed on the side of the frame to ensure smooth cable feeding and avoid problems such as jamming and friction damage during cable feeding. In addition, the cable storage wheel can store a certain amount of cable, which helps to buffer the tension changes of the cable during untwisting and subsequent winding, and improves the stability and continuity of the entire production process.

[0026] See the attached drawings. The double-disc vertical untwisting machine described in this embodiment includes a frame 1, which has two untwisting stations. Each untwisting station has an untwisting assembly. The untwisting assembly includes a vertical rocker arm 2, which has a hollow upper rotating shaft 21 and a lower rotating shaft 22 at its upper and lower ends. The rocker arm 2 can be rotatably mounted on the frame 1 via bearings 3.

[0027] Two wire feeding arms 4 are rotatably mounted on the same side of the frame 1. The front end of the wire feeding arm 4 is provided with a wire storage wheel 41. The cables of the two I-beam wire wheels 5 are finally fed from the same side, and the wire feeding tension is adjusted by the wire feeding arm 4 and the wire storage wheel 41.

[0028] A drive motor 51 is provided between the two unwinding stations. A first pulley 52 is fixed on the lower rotation shaft 22 of the vertical rocker arm 2. A second pulley 53 is mounted on the output shaft of the drive motor 51. The second pulley 53 is connected to the first pulley 52 on both sides via two belts. The drive motor 51 can drive the first pulley 52 through the second pulley 53, thereby driving the two vertical rocker arms 2 to rotate synchronously.

[0029] The vertical cradle 2 houses an I-beam reel 5 and a pay-off motor 61 that drives the I-beam reel 5 to rotate. The vertical cradle 2 has a fixed top 62 and a movable top 63 on its left and right sides, respectively, which are clamped at the center holes on both sides of the I-beam reel 5. A rotating handle 65 is provided on one side of the movable top 63, which can drive the movable top 63 towards the fixed top 62, thereby fixing the I-beam reel 5.

[0030] The vertical rocker arm 2 is provided with a torsion bow seat 71 at each of its upper and lower ends, and two torsion bow belts 72 are symmetrically arranged between the two torsion bow seats 71; the inner side of the torsion bow belt 72 is provided with multiple sets of guide components, each set of guide components including a wire threading seat with holes 73 and a guide auxiliary wheel 74.

[0031] Multiple sets of guide wheels are installed above and below the vertical cradle 2.

The cable head on the I-beam wire reel 5 first enters the hollow upper rotating shaft 21 along the upper guide wheel 81. After being reversed by the first guide wheel 82, it passes through the untwisting bow belt 72 on one side and passes through all the perforated wire seats 73 and guide auxiliary wheels 74 on the inner side of the untwisting bow belt 72 in sequence. Then, it enters the hollow lower rotating shaft 22 through the second guide wheel 83. After being reversed by the lower guide wheel 84, the reversed cable enters the wire storage reel 41 through multiple third guide wheels 85. The two I-beam wire reels 5 release the wire from the same side of the frame, so that they enter the twisted take-up machine together for the next twisting process.
