Description

Technical Field

[0001] The present invention relates to the technical field of yarn guiding and doubling equipment, and in particular provides an abrasion-proof doubling yarn guiding hook and doubling and unwinding equipment. Background Art

[0002] Doubling and unwinding equipment is a device that unwinds multiple yarns from packages (such as bobbins, cops) and combines them into a single composite yarn by mechanical means. However, in the existing equipment, during unwinding and combining, the mechanical vibration is large, which leads to yarn damage. Moreover, the tensioner has low precision and cannot respond to the dynamic changes of the yarn in real time, resulting in tension differences when multiple yarns are combined, and further leading to broken ends, weak twists or uneven yarn thickness. In addition, during the doubling process, due to the high-speed operation of the yarn, the friction damage to the yarn guiding rod is very large. As a result, the existing yarn guiding rods are severely worn after 1 to 1.5 years of use and need to be removed for chrome plating. The workload of disassembling and installing the yarn guiding rods is relatively large, and the cost of chrome plating is also relatively high. At the same time, the worn yarn guiding rods are prone to bifurcation, seriously affecting the quality of the yarn. Summary of the Invention

[0038] For example, in one embodiment: when it is necessary to de-wind and align the yarns, one end of the multiple yarns is passed through the yarn guide roller 31 and multiple wear-resistant aligning yarn guide hooks, and then is wound on the outer wall of the first differential drum 464, and then is wound in sequence through the reversing adjustment wheel 459, the second differential drum 458, the fixed reversing wheel 52 and the initial tensioning wheel 56, and then is wound on the aligning guide rod 61, and then the pressure hook 652 and the aligning pressure arm 72 are opened, and the multiple yarns are wound in sequence through the first tensioning roller 62, the second tensioning roller 63, the elastic air outlet cylinder 645, the two first aligning rollers 71, the aligning pressure wheel 73, the adjusting wheel 741, the second aligning roller 75 and the third aligning roller 76, and finally The first drive motor 41 and the second drive motor 42 are then started, and the second drive motor 42 drives the first drive wheel 453 to rotate, thereby causing the differential hollow shaft 452, the first differential drum 454, the first differential rotating ring 463 and the first differential rotating drum 464 to rotate accordingly. Moreover, the first drive motor 41 drives the second drive wheel 457 to rotate, thereby causing the differential shaft 456, the second differential drum 458, the second differential rotating ring 472 and the second differential rotating drum 473 to rotate. At the same time, the tension detector 210 monitors the tensioning state of multiple yarns to adjust the rotation speeds of the first drive motor 41 and the second drive motor 42 respectively. , so that the multiple yarns are differentially combined and tightly wound, and dynamically adjusted. Subsequently, the initial tensioning cylinder 53 will be started, thereby driving the initial tensioning arm 55 to rotate, so that the initial tensioning wheel 56 moves with it, and the combined multiple yarns are tightened and initially tensioned. At the same time, the buffer motor 66 will start to drive the buffer element 64 to rotate, and the combined multiple yarns follow forward. At the same time, when it moves forward, the wire pressing hook 652 is against the combined multiple yarns, and the tensioning sensor 653 will monitor the tension to ensure that the tension is stable and meets the tensioning requirements, and the wire taking-up motor 790 will start to make the combined multiple yarns move forward for winding. The two first doubling rollers 71, the doubling pressure wheel 73, the adjusting wheel 741, the second doubling roller 75 and the third doubling roller 76 will twist and align them again. At the same time, the doubling sensor 651 will monitor the effect of the upper doubling and send it to the doubling adjustment cylinder 74 in real time for real-time adjustment. In addition, the pressing cylinder 77 will start, thereby driving the pressing slide 771 to slide along the two pressing slides 78, so that the bottom surface of the pressing monitor 772 is against the outer wall of the combined multiple yarns to press them. At the same time, the pressing monitor 772 will monitor whether there are "bamboo node"-shaped protrusions on the surface of the yarn and the uniformity of its thickness, so as to carry out final monitoring of the produced yarn.

[0039] For example, in one embodiment: two liquid inlet holes are recessed in the top surface of the hollow cavity 211. The output end of an external spraying device is connected to a pipeline. The pipeline enters the hollow cavity 211 through the liquid inlet holes and is connected to the inner end of the air outlet hollow tube 643. When multiple yarns to be combined are wound around the elastic air outlet cylinder 645, the spraying device will be activated to form a humidifying spray. The humidifying spray flows out of the elastic air outlet cylinder 645 through the air outlet hollow tube 643 to humidify the multiple combined yarns and prevent them from breaking. At the same time, the rotation of the buffer motor 66 will cause the rotating blade 662 to rotate, generating a blowing air flow to blow the yarns, preventing over-wetting and preventing the humidifying spray from accumulating around the elastic air outlet cylinder 645 during long-term operation, resulting in local over-wetting.

[0040] When vibration occurs, it will cause the multiple combined yarns to vibrate and contract synchronously, causing the middle part of the elastic air outlet cylinder 645 to compress and deform inward, causing the sliding ring 646 to slide outward and the multiple return springs 649 to extend to absorb the vibration force. At the same time, it will squeeze the elastic air outlet cylinder 645 to eject more humidifying spray to quickly humidify the yarns, prevent breakage, and prevent the yarns from slipping off.
