Description

Technical Field

[0001] The invention relates to the technical field of winding machines, in particular to an automatic cross-winding winding machine for nylon yarns. Background Art

[0002] As the last process of spinning and the first process of weaving, winding plays a "bridge" role in connecting the upper and lower processes, and therefore occupies an important position in the textile field.

[0003] The primary task of winding is to change the package and increase the yarn capacity. Winding connects smaller bobbins (or hanks) to create larger bobbins. One bobbin can hold the equivalent of more than twenty bobbins. These bobbins are used for warping, twisting, weft winding, dyeing, weft yarn for shuttleless looms, and knitting. Using bobbins directly in these processes would result in excessive downtime, hindering production efficiency and product quality. Therefore, increasing the package capacity is essential for improving productivity and quality in subsequent processes.

[0004] When winding, the yarns of different bobbins need to be pulled into the same joining channel first, and the thread ends are located outside the joining channel. Two false twist channels are provided outside the joining channel, and the thread ends are sucked into the false twist channels by using negative pressure for false twisting. Then, the fluffy thread ends after false twisting are pulled into the same joining channel, and a tangential airflow is introduced into the joining channel to automatically twist and connect the two fluffy thread ends together. The time for automatic connection largely determines the production efficiency. However, the above series of processes make the existing winding machine still need a lot of time when connecting the yarns because of the complex automatic twisting steps required to perform on the two yarns, which limits the winding efficiency. In particular, after the two thread ends have been false twisted and become fluffy, they still need to be pulled into the false twist channel again. This process wastes time and increases the work steps and maintenance difficulty. Summary of the Invention

[0015] The beneficial effects of the present invention are:

[0016] The pneumatic twisting system is installed on the frame, and the two wire tube supply devices are rotatably installed on the frame. The wire tube supply device is used to clamp the silk wire tube, and the silk wire tube is rotatably installed on the wire tube supply device. The wire tube supply device is equipped with a brake cylinder for braking the silk wire tube. The pneumatic twisting system is located on the side of the wire tube supply device to realize separate false twisting and twisting of the two silk threads together. The tension stabilization system is rotatably installed on the frame to achieve tension stability. The yarn guide system is rotatably installed on the frame. The winding guide system and the winding system are both rotatably installed on the frame. The yarn guide system is located on the side of the winding system to adjust the entry position of the yarn fed into the winding guide system.

[0036] The present invention will be further described below in conjunction with the accompanying drawings:

[0037] like Figure 1 — Figure 7 As shown, this embodiment provides a nylon yarn automatic cross winding machine, including a frame 1, two wire tube supply devices 2, a pneumatic twisting system 3, a tension stabilizing system 4, a winding guide system 5, a winding system 6 and a yarn guide system 7. Figure 1 The frame 1 shown is only a part of the frame 1. In order to increase the winding efficiency, multiple sets of bobbin supply devices 2, pneumatic twisting systems 3, tension stabilization systems 4 and winding guide systems 5 can be installed on the frame 1. The pneumatic twisting system 3 is installed on the frame 1. Both bobbin supply devices 2 are rotatably installed on the frame 1. The bobbin supply devices 2 are used to clamp the silk bobbins. The silk bobbins are rotatably installed on the bobbin supply devices 2. The bobbin supply devices 2 are equipped with a brake cylinder for braking the silk bobbins. This is a prior art and will not be described in detail here. The pneumatic twisting system 3 is located on the side of the wire tube feeding device 2 to realize separate false twisting and twisting of the two silk threads together. The tension stabilization system 4 is rotatably installed on the frame 1 to achieve tension stability. The yarn guide system 7 is rotatably installed on the frame 1. The winding guide system 5 and the winding system 6 are both rotatably installed on the frame 1. The yarn guide system 7 is located on the side of the winding system 6, thereby adjusting the entry position of the yarn fed into the winding guide system 5. The yarn guide system 7 is installed on the side of the winding guide system 5 to realize the swinging winding of the yarn.

[0038] The pneumatic twisting system 3 includes a suction pipe 31, a separator 32, two ventilation devices 33, a tail material sensing brake device 34 and a new material monitoring device. The new material monitoring device is installed on the side of the suction pipe 31 away from the corresponding wire tube feeding device 2. The new material monitoring device is a photoelectric sensor, which is electrically connected to the wire tube feeding device 2 through a controller. Then, when the yarn reaches the side of the suction pipe 31 away from the corresponding wire tube feeding device 2, the controller controls the wire tube feeding device 2 to stop releasing the yarn. A suction slot 311 is provided at a position of the suction pipe 31 close to the corresponding wire tube feeding device 2 to absorb the silk thread ends on the silk thread tube. The separator 32 is installed at the end of the suction pipe 31 away from the suction slot 311. It is worth noting that when the suction slot 311 is required to absorb the thread ends, the corresponding ventilation device 33 is under negative pressure. When inhaling, the separating device 32 rises and falls along the suction pipe 31. The rising separating device 32 separates the suction pipe 31 away from the suction slot 311 into two breaking up chambers, breaking up the end of the tail material and the beginning of the new material respectively. The tail material referred to in this article is the thread end of the previous silk thread, and the new material refers to the thread end of the next silk thread. The descending separating device 32 merges the two breaking up chambers on the side of the suction pipe 31 away from the suction slot 311 into one twisting chamber, and then twists the end of the broken up tail material and the beginning of the new material. Since the separating device 32 is used to merge the two breaking up chambers into one twisting chamber, the traditional method of transporting and pulling the two broken up yarns and then pulling the two broken up yarns into the same joining channel causes a waste of time, thereby simplifying the mechanism.

[0039] The two ventilation devices 33 are driven by the cylinder to slide along the suction pipe 31. The two ventilation devices 33 are connected to the two scattered chambers respectively. In order to facilitate twisting, one of the two ventilation devices 33 points upward and the other points downward. In this way, when the scattered chambers are merged into a twisting chamber, the two ventilation devices 33 can drive the two scattered silk thread ends to twist. In order to facilitate the sliding of the ventilation devices 33, a ventilation chute 312 for the ventilation devices 33 to slide is provided on the suction pipe 31. In order to achieve the sliding sealing of the ventilation chute 312, a cover plate covering the ventilation chute 312 is installed on the ventilation device 33 to avoid air leakage. The tail material sensing brake device 34 is slidably installed on the side of the suction pipe 31 away from the suction seam 311, and the tail material has tension. When the tail material sense brake device 34 is in tension, the tail material supports the tail material sensing brake device 34; when the tail material loses tension, the tail material sensing brake device 34 descends and clamps the tail material. In order to make the tail material sensing brake device 34 and the tail material generate sufficient friction, a rubber block is provided at the position of the suction pipe 31 corresponding to the tail material sensing brake device 34, so that the tail material sensing brake device 34 presses the yarn on the rubber block and fixes it. When the separating device 32 rises, the two ventilation devices 33 move away from each other, so that the end of the tail material and the beginning of the new material have an intersection section. The ventilation device 33 corresponding to the tail material is closer to the wire tube supply device 2 than the ventilation device 33 corresponding to the new material. When the tail material sensing brake device 34 descends, the airflow directions of the two ventilation devices 33 are opposite, thereby realizing spiral airflow, thereby realizing twisting.

[0040] In order to fully describe the motion of the two ventilation devices 33 and to clearly describe how the two yarns to be connected are automatically twisted in the twisting chamber mentioned above, please refer to the attached Figure 2 To the attached Figure 5 .

[0041] In the attached Figure 2 In the process, after the previous yarn leaves the bobbin feeding device 2, the yarn loses tension, and the tail material sensing brake device 34 loses the support of the yarn and falls, and then the tail material sensing brake device 34 fixes the previous yarn, and the ventilation device 33 corresponding to the tail material slides close to the bobbin feeding device 2, and the ventilation device 33 inhales air, while the other ventilation device 33 slides to the side away from the bobbin feeding device 2 and inhales air, so that the two yarns have an overlapping area, and the two ventilation devices 33 that inhale air cause the corresponding thread ends to be falsely twisted.

[0042] In the attached Figure 3 In the process, the separating device 32 descends so that the two yarn-breaking chambers are merged into one twisting chamber, and the two ventilation devices 33 blow air respectively so that the two yarns in the twisting chamber are rolled and twisted.

[0043] In the attached Figure 4 In the middle, the winding system 6 continues to wind, and after the yarn obtains tension, the tail material sensing brake device 34 is lifted again, and the yarn can be smoothly transported.

[0044] In the attached Figure 5 In the process, since the two wire tube supply devices 2 alternately clamp the wire tubes, the wire tubes originally in the attached Figure 2 The ventilator 33 near the wire tube supply device 2 slides away from the wire tube supply device 2. Figure 2 The ventilation device 33 away from the bobbin supply device 2 slides toward the bobbin supply device 2 so that the yarn has an overlapping area again, which is convenient for twisting again.

[0045] Specifically, the winding machine also includes a felt system 8, which includes a felt screw 81, a felt roller 83, a felt cover 84, a felt nut 85 and a felt spring 86. The felt roller 83 is rotatably mounted on the felt screw 81, and the felt screw 81 is mounted on the frame 1. The felt nut 85 and the felt screw 81 are mounted through a threaded pair. The two ends of the felt spring 86 press the frame 1 and the felt roller 83 respectively. The felt nut 85 presses the felt cover 84 onto the felt roller 83, thereby realizing the removal of yarn floating hair and uniform correction of yarn size when the yarn passes around the felt roller 83.

[0046] Specifically, the winding machine also includes a paraffin supply system 9, which includes a paraffin wheel. A paraffin mounting long hole 11 is provided on the frame 1. The paraffin wheel is rotatably mounted on the paraffin mounting long hole 11. The yarn passes around the paraffin wheel so that the yarn is coated with paraffin, which makes the yarn transportation smooth.

[0047] Specifically, the winding guide system 5 includes a winding guide rod 51 and a winding guide wheel 52. The winding guide rod 51 is slidably mounted on the frame 1, and the winding guide wheel 52 is slidably mounted on the winding guide rod 51, thereby realizing the adjustment of the position of the winding guide wheel 52.

[0048] Specifically, the winding system 6 includes a winding motor and a winding shaft. The winding motor is installed on the frame 1, and the winding shaft is installed at the output end of the winding motor to achieve winding.

[0049] Specifically, the yarn guide system 7 includes a yarn guide wheel, and a winding roller is provided with a plurality of reciprocating guide grooves to achieve reciprocating swing of the yarn.

[0050] Specifically, the tension stabilizing system 4 includes a tension swing arm 41, which is rotatably mounted on the frame 1. A tension torsion spring is provided between the tension swing arm 41 and the frame 1 to maintain the tension of the yarn.

[0051] Specifically, a friction rubber plate is provided on one side of the frame 1 close to the tail material induction brake device 34 to achieve the clamping of the tail material.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
