Description

Technical Field

[0001] This invention relates to the field of optoelectronic cables, specifically to a high-speed double-head yarn binding machine with anti-twist properties. Background Technology

[0002] With the rapid development of communication technology, the demand for optoelectronic cables is also increasing rapidly. Optoelectronic cables are high-speed transmission media for communication signals, and can be classified into various types according to their uses. Among them, stranded cables are a type of cable with better transmission performance in modern life.

[0003] The SZ stranding process involves rotating and winding multiple loose tubes containing optical fibers around a central reinforcing core along the S or Z direction, and then securing the stranded cable with yarn using a yarn-tying machine.

[0004] In existing yarn-tying machines, the twisting of the stranded cable can occur after yarn tying, that is, the number of turns of the loose tube is reduced, causing the loose tube to be parallel to the reinforcing core. The pitch at this point also increases and becomes unstable, which seriously affects the quality and performance of the optoelectronic cable. Summary of the Invention

[0025] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0026] As described in the background section of this application, the SZ stranding process involves rotating and winding multiple loose tubes containing optical fibers around a central reinforcing core along the S or Z direction, and then securing the stranded cable by binding the yarn with a yarn binding machine.

[0027] The inventors of this application have discovered that in existing yarn-tying machines, stranded cables will exhibit a twisting phenomenon after yarn tying, that is, the number of turns of the loose tube is reduced, causing the loose tube to appear parallel to the reinforcing core. The pitch at this point also increases and becomes unstable, which seriously affects the quality and performance of the optoelectronic cable.

[0028] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows: Figure 1 This is a schematic diagram of a high-speed double-head yarn tying machine with anti-twist mechanism according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the torque-damping mechanism in an embodiment of the present invention. Figure 3 As described in the embodiments of the present invention Figure 2 Enlarged view of point A in the image. Figure 4 As described in the embodiments of the present invention Figure 2 Enlarged view of point B in the image. Figure 5 This is a schematic diagram of the torque resisting seat in an embodiment of the present invention. Figure 6 This is a schematic diagram of the guide wheel assembly in an embodiment of the present invention. Figure 7 This is a schematic diagram of the rotating hinge head in an embodiment of the present invention. Figures 1 to 7 As shown, the high-speed double-head yarn binding machine with anti-torsion mechanism of this embodiment includes: yarn binding machine 1, connecting sleeve 2 and anti-torsion mechanism.

[0029] The rotating shaft 11 of the high-speed double-head yarn binding machine 1 is rotatably mounted on the frame via a bearing seat 12, and the rotating shaft 11 of the yarn binding machine 1 has a through-passage inlet and outlet channel along the axial direction.

[0030] The yarn binding machine 1 includes: a rotating twisting head 13 and a forming mold 14.

[0031] The torque-damping mechanism includes: a fixed shaft 31, a torque-damping seat 32, and a guide wheel assembly 33.

[0032] The fixed shaft 31 of the anti-torsion mechanism is fixedly installed on the frame of the yarn binding machine 1, and the fixed shaft 31 passes through the inlet and outlet channel of the rotating shaft 11. The central axis of the fixed shaft 31 coincides with the central axis of the rotating shaft 11. The fixed shaft 31 also has a through channel along the axial direction. The fixed shaft 31 is a non-rotating shaft.

[0033] One end of the torque-blocking seat 32 is fixedly mounted on the fixed shaft 31 and located at the inlet (front end of the inlet) of the inlet and outlet channel of the rotating shaft 11. The torque-blocking seat 32 extends axially outward to the rotating shaft 11, and the interior of the torque-blocking seat 32 is provided with a receiving cavity.

[0034] The guide wheel assembly 33 is mounted on the torque-blocking seat 32 and is located within the receiving cavity of the torque-blocking seat 32.

[0035] One end of the connecting sleeve 2 is mounted on the bearing seat 12, and the connecting sleeve 2 is fitted onto the outside of the anti-torsion seat 32. When the rotating shaft 11 of the yarn binding machine 1 rotates, the rotating shaft 11 drives the connecting sleeve 2 to rotate together.

[0036] The rotating twisting head 13 and the forming mold 14 of the yarn binding machine 1 are located at the other end of the connecting sleeve 2. The rotating twisting head 13 is fixedly connected to the connecting sleeve 2, and the connecting sleeve 2 drives the rotating twisting head 13 to rotate together. The forming mold 14 is fixedly set on the torque-resistant seat 32, and the through hole of the forming mold 14 is the yarn binding point of the SZ twisted cable.

[0037] In this embodiment, the rotating twisting head and forming mold of the yarn binding machine are moved forward by the connecting sleeve, and the guide wheel group of the anti-torsion mechanism is set between the forming mold and the bearing seat. After multiple loose tubes come out of the SZ twisting device, they enter the yarn binding machine under the traction of the traction mechanism and pass out through the channel of the fixed shaft. The yarn binding machine is equipped with multiple yarn bobbins. The yarn on the yarn bobbins passes through the internal wiring of the yarn binding machine, reaches the rotating twisting head, and after twisting, travels to the forming mold. The twisted cable is tied at the through hole of the forming mold. After the twisting and tying are completed, the formed cable is clamped and fixed in the anti-torsion seat by the guide wheel group. The guide wheel group applies anti-torsion force to the cable, making the twisted cable more stable, preventing the twisted cable from untwisting, and improving the quality and performance of the twisted cable.

[0038] It is not difficult to see from the above that the anti-torsion high-speed double-head yarn binding machine of this embodiment, by setting up a yarn binding machine, a connecting sleeve and a torsion blocking mechanism, has a through-through inlet and outlet channel on the rotating shaft of the yarn binding machine. The torsion blocking mechanism includes: a fixed shaft, a torsion blocking seat and a guide wheel assembly. The fixed shaft passes through the inlet and outlet channel of the rotating shaft, the torsion blocking seat is set on the fixed shaft, the guide wheel assembly is set on the torsion blocking seat, the connecting sleeve is set on the bearing seat and sleeved on the outside of the torsion blocking seat, the rotating twisting head of the yarn binding machine is set on the connecting sleeve, and the forming mold is set on the torsion blocking seat. In this embodiment, the high-speed double-head yarn binding machine with anti-twist feature moves the rotating twisting head and forming mold forward via a connecting sleeve. Multiple loose tubes emerge from the SZ twisting device, pass through the yarn binding machine, and complete the yarn binding of the twisted cable at the through hole of the forming mold. After the twisting and binding are completed, the formed cable is clamped and fixed in the anti-twist seat by the guide wheel group. The guide wheel group applies anti-twist force to the cable, making the cable more stable and preventing the twisted cable from untwisting, thus improving the performance and quality of the cable.

[0039] Optional, such as Figure 2 , Figure 4 As shown, the anti-twisting high-speed double-head yarn binding machine in this embodiment also includes: a locking mechanism 4.

[0040] The locking mechanism 4 is installed on the frame of the yarn binding machine 1, located on the outside of the outlet of the inlet and outlet channel of the rotating shaft 11 of the yarn binding machine 1.

[0041] The locking mechanism 4 includes: a base 41, a lower clamp 42, an upper clamp 43, a lock 44, and a buckle 45.

[0042] The base 41 is mounted on the frame of the yarn binding machine 1, and the lower clamp 42 is mounted on the top of the base 41.

[0043] The latch 44 is located at the top of the lower clamp 42, and the latch 44 is symmetrically located on both sides of the lower clamp 42.

[0044] One end of the fixed shaft 31 is fixedly inserted into the inner ring of the bearing in the bearing seat 12 of the yarn binding machine. The upper clamp 43 and the lower clamp 42 form a ring when spliced ​​to hold the other end of the fixed shaft 31.

[0045] The buckle 45 is semi-circular, and there are locking hooks on both sides of the buckle 45.

[0046] The buckle 45 abuts against the upper clamp 43, and the locking hook of the buckle 45 is used to engage with the lock 44. When the locking hook of the buckle 45 engages with the lock 44, the buckle 45 presses the upper clamp 43 against the lower clamp 42, and the upper clamp 43 and the lower clamp 42 complete the clamping and fixing of the fixed shaft 31.

[0047] In this embodiment, the fixed shaft is positioned and fixed by the upper clamp, lower clamp and buckle, which facilitates the installation and disassembly of the fixed shaft and also facilitates the replacement of the yarn cylinder 15 on the yarn binding machine.

[0048] Furthermore, in this embodiment, the locking mechanism 4 of the anti-twist high-speed double-head yarn binding machine also includes a connecting block 46.

[0049] The bottom end of the connecting block 46 is set on the top end of the base 41 via the third rotating shaft, and the bottom end of the lower clamp 42 is set on the connecting block 46 and connected to the top end of the connecting block 46.

[0050] In this embodiment, the lower clamp is rotatably connected to the base via a connecting block. After the upper clamp is removed, the lower clamp can be rotated and laid down, making it easier to replace the yarn bobbin of the yarn tying machine.

[0051] Furthermore, such as Figure 5 , Figure 6 , Figure 7 As shown, the anti-torsion high-speed double-head yarn binding machine in this embodiment further includes a connecting plate 34 and a swing plate 35 as its anti-torsion mechanism.

[0052] The connecting plate 34 is disposed on the torque-blocking seat 32, and the connecting plate 34 is symmetrically disposed on both sides of the receiving cavity of the torque-blocking seat 32. The connecting plate 34 is provided with a plurality of first sliding grooves 341.

[0053] The swing plate 35 is equipped with a sliding pin 351.

[0054] The swing plate 35 is rotatably mounted on the torque block 32 via the first rotating shaft 352, and the sliding pin 351 of the swing plate 35 is slidably inserted into the first sliding groove 341 of the connecting plate 34.

[0055] The two guide wheels of the guide wheel assembly 33 are rotatably mounted on the swing plate 35 via the second rotating shaft. The two guide wheels are spaced apart to clamp the twisted and bundled cable and prevent the cable from untwisting.

[0056] Furthermore, such as Figure 1 , Figure 2, Figure 4 , Figure 5 , Figure 6 As shown, the anti-torsion high-speed double-head yarn binding machine in this embodiment further includes a cylinder 36 and a steel wire rope 37 as its anti-torsion mechanism.

[0057] The two side walls of the anti-torsion seat 32 are provided with second sliding grooves 321.

[0058] The outer wall of the connecting plate 34 is provided with a pull pin 342, which is slidably inserted into the second slide groove 321 of the torque-blocking seat 32.

[0059] The cylinder 36 is mounted on the frame of the yarn binding machine 1 and is located at the outlet of the inlet / outlet channel of the rotating shaft 11 of the yarn binding machine 1.

[0060] The wire rope 37 is threaded inside the fixed shaft 31. One end of the wire rope 37 passes through the fixed shaft 31 and is fixedly connected to the pull pin 342 on the connecting plate 34. The other end of the wire rope 37 passes through the fixed shaft 31 and is connected and fixed to the movable rod of the cylinder 36.

[0061] In this embodiment, the extension and retraction of the cylinder's movable rod drives the connecting plate to move left and right via the wire rope, causing the guide wheels of the guide wheel assembly to move inward or outward, thereby adjusting the clamping force (torsional force) of the guide wheel assembly on the cable and adapting to the clamping of cables of different diameters.

[0062] Furthermore, in this embodiment, the anti-twist high-speed double-head yarn binding machine has a wire groove 311 on the circumferential sidewall of the fixed shaft 31 along the axial direction. The wire groove 311 of the fixed shaft 31 allows the wire rope 37 to be embedded, so that the wire rope 37 can be slidably hidden in the wire groove 311 of the fixed shaft 31.

[0063] Furthermore, such as Figure 4 As shown, the anti-torsion high-speed double-head yarn binding machine in this embodiment further includes a steering guide wheel 38 and a fixed wheel 39 in its anti-torsion mechanism.

[0064] Steering guide wheels 38 are symmetrically arranged on the lower clamp 42 of the locking mechanism 4, located at the exit of the inlet and outlet channel of the rotating shaft, and fixed wheels 39 are mounted on the movable rod of cylinder 36 through a fixing block.

[0065] After the wire rope 37 passes through the fixed shaft 31, it goes around the steering guide wheel 38 and is fixed on the fixed wheel 39 to facilitate the sliding of the wire rope, so as to facilitate the cylinder to pull and adjust the connecting plate.

[0066] Furthermore, such as Figure 6 As shown, in this embodiment of the anti-torsion high-speed double-head yarn binding machine, the anti-torsion mechanism has multiple sets of guide wheel groups 33, which are arranged in the receiving cavity of the anti-torsion seat 32 and spaced apart along the axial direction of the fixed shaft 31.

[0067] After being twisted and bundled, the cable passes through multiple sets of guide rollers in sequence. These guide rollers clamp the cable in turn, making it more stable and providing better resistance to torsion.

[0068] Furthermore, in this embodiment, the anti-twist high-speed double-head yarn binding machine includes a guide wheel assembly 33 comprising: a first guide wheel 331 and a second guide wheel 332.

[0069] The outer diameters of the first guide wheel 331 and the second guide wheel 332 in each guide wheel group 33 are different.

[0070] The outer side of the first guide wheel 331 is provided with a first cable groove, and the outer side of the second guide wheel 332 is provided with a second cable groove. The cable is clamped in the first cable groove of the first guide wheel 331 and the second cable groove of the second guide wheel 332.

[0071] In this embodiment, each guide wheel group uses two guide wheels with different outer diameters, which can increase the clamping force (torsional force) of the guide wheel group on the cable and improve the torsion resistance effect.

[0072] Optional, such as Figure 5 , Figure 7 As shown, in this embodiment, the high-speed double-head yarn binding machine with anti-twist mechanism has observation holes on both the connecting sleeve 2 and the anti-twist seat 32. The positions of the observation holes on the connecting sleeve 2 and the anti-twist seat 32 are corresponding. The status of the guide wheel assembly can be observed in real time through the observation holes of the connecting sleeve and the anti-twist seat.

[0073] In this invention, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0074] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
