Description

Technical Field

[0001] The present invention relates to the technical field of yarn guiding and doubling equipment, and in particular to a wear-resistant doubling and yarn guiding hook and a doubling and undoing equipment. Background Art

[0002] Doubling and undoing equipment unwinds multiple yarns from packages (such as bobbins or cops) and mechanically combines them into a composite yarn. However, existing equipment experiences significant mechanical vibration during unwinding and combining, which can damage the yarns. Furthermore, the tensioner has low precision and cannot respond to dynamic yarn changes in real time, resulting in tension differences when combining multiple yarns. This can lead to yarn breakage, weak twist, and uneven yarn thickness. Furthermore, the high speed of the yarns during the doubling process causes significant friction damage to the yarn guide rods. As a result, existing yarn guide rods become severely worn after 1-1.5 years of use, necessitating removal and chrome plating. Disassembling and installing yarn guide rods is labor-intensive and the chrome plating cost is high. Furthermore, worn yarn guide rods are prone to splitting, seriously affecting yarn quality.

[0040] For example, in one embodiment: when it is necessary to de-thread 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 wound on the outer wall of the first differential drum 464, and then 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 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 It is wound in the take-up roller 793, and then the first drive motor 41 and the second drive motor 42 are started. The second drive motor 42 will drive 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 will drive 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 will monitor the tensioning status of multiple yarns to adjust the speed of the first drive motor 41 and the second drive motor 42 respectively. , thereby making the multiple yarns therein differentially combined and tightly wound, and dynamically adjusted, then, the initial tensioning cylinder 53 will start, thereby driving the initial tensioning rotating arm 55 to rotate, so that the initial tensioning rotating wheel 56 follows and moves, tightening and initially applying tension to the multiple yarns combined, at the same time, the buffer motor 66 will start to drive the buffer element 64 to rotate, and make the multiple yarns combined follow forward, at the same time, when it moves forward, the thread pressing hook 652 will be against the multiple yarns combined, the tensioning sensor 653 will monitor the tension to ensure that the tension is stable and meets the tensioning requirements, and the take-up motor 790 will start, thereby making the multiple yarns combined move forward and be wound, 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 dart 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, and then drive 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 multiple yarns to be combined and 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 to carry out final monitoring of the produced yarn.

[0041] For example, in one embodiment, two liquid inlet holes are recessed on the top surface of the hollow cavity 211. The output end of the external spray device is connected to a pipe, which enters the hollow cavity 211 through the liquid inlet holes and connects 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 spray device will start and form a humidifying spray. The humidifying spray flows out of the elastic air outlet cylinder 645 through the air outlet hollow tube 643, humidifying the multiple combined yarns and preventing them from breaking. At the same time, the rotation of the buffer motor 66 will cause the rotor 662 to rotate, generating a blow-off airflow, which in turn blows the yarn, preventing over-humidification and preventing the humidifying spray from accumulating around the elastic air outlet cylinder 645 during long-term operation, resulting in localized over-humidification.

[0042] When vibration occurs, the multiple combined yarns will vibrate and contract synchronously, causing the middle part of the elastic air outlet cylinder 645 to be compressed and deformed inward, causing the sliding ring 646 to slide outward, and causing the multiple return springs 649 to extend to absorb the vibration force. At the same time, the elastic air outlet cylinder 645 will be squeezed to cause more humidifying spray to be sprayed out, quickly humidifying the yarn, preventing breakage, and preventing the yarn from slipping.
