Description

Technical Field

[0001] The present invention relates to the technical field of winding machines, and particularly to an automatic cross-winding winding machine for polyamide filaments. Background Art

[0002] Winding, as the last process of spinning and the first process of weaving, plays a connecting "bridge" role, and thus occupies an important position in the textile field.

[0003] The main task of winding is to change the package and increase the yarn storage capacity of the yarn package. By winding, the tube yarns (or hank yarns) with less capacity are connected to form a tube with a larger capacity. The capacity of one tube is equivalent to more than twenty tube yarns. Tubes can be used for warping, doubling, pirn winding, dyeing, weft yarns on shuttleless looms, and knitting yarns, etc. If tube yarns are directly used in these processes, it will cause too much downtime, affecting the improvement of production efficiency and the quality of products. Therefore, increasing the package capacity is a necessary condition for improving the productivity and quality of subsequent processes.

[0004] During winding, the yarns of different tube yarns need to be respectively drawn into the same splicing channel first, and the head positions are located outside the splicing channel. There are two false-twist channels outside the splicing channel. The head is sucked into the false-twist channel by negative pressure for false twisting, and then the fluffy head after false twisting is drawn into the same splicing channel. The splicing channel is introduced with tangential air flow to automatically twist and butt the two fluffy heads together. The automatic butting time largely determines the production efficiency. However, the above series of processes make the existing winding machines still require more time for yarn splicing due to the need for complex automatic twisting steps for two yarns, which limits the winding efficiency. Especially after the two heads have been false-twisted and become fluffy, they still need to be drawn into the false-twist channel again, which wastes time, increases the working steps and the maintenance difficulty. Summary of the Invention

[0005] To overcome the technical defects existing in the prior art, the present invention provides an automatic cross-winding winding machine for polyamide filaments to quickly realize wire connection.

[0006] The technical solution adopted by the present invention is: The nylon filament automatic cross winding and coning machine includes a frame, two yarn tube supply devices, a pneumatic twisting system, a tension stabilizing system, a winding guiding system, a winding-up system and a yarn guiding system. The pneumatic twisting system is installed on the frame. The two yarn tube supply devices are rotatably installed on the frame. The pneumatic twisting system is located on the side of the yarn tube supply device. The tension stabilizing system is rotatably installed on the frame. The yarn guiding system is rotatably installed on the frame. The winding guiding system and the winding-up system are rotatably installed on the frame. The yarn guiding system is located on the side of the winding-up system. The yarn guiding system is installed on the side of the winding guiding system. The pneumatic twisting system includes a suction pipe, a separating device, two ventilation devices, a tail stock induction braking device and a new material monitoring device. The new material monitoring device is installed on the side of the suction pipe far from the corresponding yarn tube supply device. A suction slit is provided at the position of the suction pipe close to the corresponding yarn tube supply device. The separating device is installed at the end of the suction pipe far from the suction slit. The separating device moves up and down along the suction pipe. When the separating device rises, the separating device divides the side of the suction pipe far from the suction slit into two dispersing chambers. When the separating device descends, the two dispersing chambers on the side of the suction pipe far from the suction slit are combined into a twisting chamber. The two ventilation devices are respectively slidably arranged along the suction pipe. The two ventilation devices are respectively communicated with the two dispersing chambers. One of the two ventilation devices points upward and the other points downward. The tail stock induction braking device is slidably installed on the side of the suction pipe far from the suction slit. When the tail stock has tension, the tail stock supports the tail stock induction braking device. When the tail stock loses tension, the tail stock induction braking device descends to clamp the tail stock. When the separating device rises, the two ventilation devices move away from each other. The ventilation device corresponding to the tail stock is closer to the yarn tube supply device than the ventilation device corresponding to the new material. When the tail stock induction braking device descends, the air flow directions of the two ventilation devices are opposite.

[0007] Preferably, the coning machine further includes a felt system. The felt system includes a felt screw, a felt roller, a felt cover plate, a felt nut and a felt spring. The felt roller is rotatably installed on the felt screw. The felt screw is installed on the frame. The felt nut is installed on the felt screw through a thread pair. The two ends of the felt spring respectively press on the frame and the felt roller. The felt nut presses the felt cover plate on the felt roller.

[0008] Preferably, the coning machine further includes a paraffin wax supply system. The paraffin wax supply system includes a paraffin wax wheel. A long paraffin wax installation hole is provided on the frame. The paraffin wax wheel is rotatably installed in the paraffin wax installation long hole.

[0009] Preferably, the winding guiding system includes a winding guiding rod and a winding guiding wheel. The winding guiding rod is slidably installed on the frame. The winding guiding wheel is slidably installed on the winding guiding rod.

[0010] Preferably, the winding system includes a winding motor and a winding shaft. The winding motor is installed on the frame, and the winding shaft is installed at the output end of the winding motor.

[0011] Preferably, the yarn guiding system includes a yarn guiding wheel, and a plurality of reciprocating guiding grooves are provided on the winding roller.

[0012] Preferably, the tension stabilizing system includes a tension swing arm. The tension swing arm is rotatably installed on the frame, and a tension torsion spring is provided between the tension swing arm and the frame.

[0013] Preferably, a friction rubber plate is provided on one side of the frame close to the tail stock induction braking device.

[0014] The beneficial effects of the present invention are as follows: The pneumatic twisting system is installed on the frame. The two wire tube feeding devices are rotatably installed on the frame. The wire tube feeding devices are used to clamp the silk wire tubes. The silk wire tubes are rotatably installed on the wire tube feeding devices. A braking cylinder for braking the silk wire tubes is installed on the wire tube feeding devices. The pneumatic twisting system is located on the side of the wire tube feeding devices to respectively false-twist and twist together two silk threads. The tension stabilizing system is rotatably installed on the frame to achieve tension stability. The yarn guiding system is rotatably installed on the frame. The winding guiding system and the winding system are rotatably installed on the frame. The yarn guiding system is located on the side of the winding system to adjust the entry position of the yarn fed into the winding guiding system. The yarn guiding system is installed on the side of the winding guiding system to achieve the oscillating winding of the yarn.

[0015] The pneumatic twisting system includes a suction pipe, a separating device, two ventilation devices, a tail-end induction braking device, and a new material monitoring device. The new material monitoring device is installed on the side of the suction pipe away from the corresponding wire tube supply device. The new material monitoring device is a photoelectric sensor, and this photoelectric sensor is electrically connected to the wire tube supply device through a controller. Thus, when the yarn reaches the side of the suction pipe away from the corresponding wire tube supply device, the controller controls the wire tube supply device to stop releasing the yarn. A suction slit is provided at the position of the suction pipe close to the corresponding wire tube supply device to suck the thread end of the wire on the wire tube. The separating device is installed at the end of the suction pipe away from the suction slit. When it is necessary to suck the thread end by the suction slit, the corresponding ventilation device sucks air under negative pressure, and the separating device moves up and down along the suction pipe. When the separating device rises, the separating device divides the side of the suction pipe away from the suction slit into two dispersing chambers, respectively dispersing the end of the tail material and the beginning of the new material. When the separating device descends, the two dispersing chambers on the side of the suction pipe away from the suction slit are combined into a twisting chamber, and then the end of the tail material and the beginning of the new material that have been dispersed are twisted. Since the separating device 32 is used to combine the two dispersing chambers into one twisting chamber, it avoids the time waste caused by the traditional method of transporting and pulling two dispersed yarns and then pulling the two dispersed yarns into the same joining channel, and simplifies the mechanism.

[0016] The two ventilation devices can slide along the suction pipe respectively. The two ventilation devices are respectively connected to the two dispersing chambers. For the convenience of twisting, one of the two ventilation devices points upward and the other points downward. In this way, when the two dispersing chambers are combined into one twisting chamber, the two dispersed thread ends can be driven to twist. For the convenience of the ventilation device to slide, ventilation sliding grooves for the ventilation device to slide are provided on the suction pipe. In order to achieve the sliding seal of the ventilation sliding groove, a cover plate covering the ventilation sliding groove is installed on the ventilation device to avoid air leakage. The tail-end induction braking device is slidably installed on the side of the suction pipe away from the suction slit. When the tail material has tension, the tail material supports the tail-end induction braking device. When the tail material loses tension, the tail-end induction braking device descends and then clamps the tail material. In order to make the tail-end induction braking device generate sufficient friction with the tail material, rubber blocks are provided at the positions of the suction pipe corresponding to the tail-end induction braking device, facilitating the tail-end induction braking device to press the yarn on the rubber blocks to fix it. When the separating device rises, the two ventilation devices move away from each other, making the end of the tail material and the beginning of the new material have an intersection section. The ventilation device corresponding to the tail material is closer to the wire tube supply device than the ventilation device corresponding to the new material. When the tail-end induction braking device descends, the air flow directions of the two ventilation devices are opposite, thus realizing spiral air flow and achieving twisting.

[0025] The present invention will be further described below with reference to the accompanying drawings: As Figure 1 — Figure 7 shown, this embodiment provides an automatic cross - winding creel for polyamide filaments, which includes a frame 1, two tube - line supply devices 2, a pneumatic twisting system 3, a tension - stabilizing system 4, a winding guiding system 5, a rewinding system 6 and a yarn guiding system 7. Figure 1The shown frame 1 is only a part of the frame 1. To increase the winding efficiency, multiple sets of thread tube supply devices 2, pneumatic twisting systems 3, tension stabilizing systems 4, and winding guiding systems 5 can be installed on the frame 1. The pneumatic twisting system 3 is installed on the frame 1. Two thread tube supply devices 2 are rotatably installed on the frame 1. The thread tube supply device 2 is used to clamp the silk thread tube. The silk thread tube is rotatably installed on the thread tube supply device 2. A braking cylinder for braking the silk thread tube is installed on the thread tube supply device 2. This is the prior art and will not be elaborated here. The pneumatic twisting system 3 is located on the side of the thread tube supply device 2 to separately false twist and twist together two silk threads. The tension stabilizing system 4 is rotatably installed on the frame 1 to achieve tension stability. The yarn guiding system 7 is rotatably installed on the frame 1. The winding guiding system 5 and the winding system 6 are rotatably installed on the frame 1. The yarn guiding system 7 is located on the side of the winding system 6 to adjust the entry position of the yarn fed into the winding guiding system 5. The yarn guiding system 7 is installed on the side of the winding guiding system 5 to achieve the oscillating winding of the yarn.

[0026] The pneumatic twisting system 3 includes a suction tube 31, a separating device 32, two ventilation devices 33, a tail material induction braking device 34, and a new material monitoring device. The new material monitoring device is installed on the side of the suction tube 31 far from the corresponding thread tube supply device 2. The new material monitoring device is a photoelectric sensor, and this photoelectric sensor is electrically connected to the thread tube supply device 2 through a controller. Thus, when the yarn reaches the side of the suction tube 31 far from the corresponding thread tube supply device 2, the controller controls the thread tube supply device 2 to stop releasing the yarn. An inhalation slit 311 is provided at the position of the suction tube 31 close to the corresponding thread tube supply device 2 to suck the thread end of the silk thread tube. The separating device 32 is installed at one end of the suction tube 31 far from the inhalation slit 311. It should be noted that when the inhalation slit 311 needs to suck the thread end, the corresponding ventilation device 33 sucks air under negative pressure, and the separating device 32 moves up and down along the suction tube 31. When the separating device 32 rises, the separating device 32 separates the side of the suction tube 31 far from the inhalation slit 311 into two dispersion chambers, respectively dispersing the end of the tail material and the beginning of the new material. The tail material referred to herein is the thread end of the previous silk thread, and the new material refers to the thread end of the next silk thread. When the separating device 32 descends, the two dispersion chambers on the side of the suction tube 31 far from the inhalation slit 311 are combined into a twisting chamber, and then the end of the already dispersed tail material and the beginning of the new material are twisted. Since the separating device 32 is used to combine the two dispersion chambers into a twisting chamber, it avoids the time waste caused by the traditional method of transporting and pulling two dispersed yarns and then pulling the two dispersed yarns into the same joining channel, simplifying the mechanism.

[0027] Two ventilation devices 33 can slide along the suction pipe 31 driven by the cylinder respectively. The two ventilation devices 33 are respectively connected to two dispersion chambers. For the convenience of twisting, one of the two ventilation devices 33 points upward and the other points downward. In this way, when the two ventilation devices 33 merge into a twisting chamber in the dispersion chamber, they can drive the heads of the two dispersed silk threads to twist. For the convenience of the sliding of the ventilation device 33, a ventilation chute 312 for the sliding of the ventilation device 33 is provided on the suction pipe 31. In order to achieve the sliding seal 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 stock induction braking device 34 is slidably installed on the side of the suction pipe 31 far from the suction slit 311. When the tail stock has tension, the tail stock supports the tail stock induction braking device 34. When the tail stock loses tension, the tail stock induction braking device 34 descends and then clamps the tail stock. In order to enable the tail stock induction braking device 34 to generate sufficient friction with the tail stock, a rubber block is provided at the position of the suction pipe 31 corresponding to the tail stock induction braking device 34, so that the tail stock induction braking device 34 can press the yarn on the rubber block to fix it. When the separation device 32 rises, the two ventilation devices 33 move away from each other, so that there is an intersection section at the end of the tail stock and the beginning of the new material. The ventilation device 33 corresponding to the tail stock is closer to the yarn tube supply device 2 than the ventilation device 33 corresponding to the new material. When the tail stock induction braking device 34 descends, the air flow directions of the two ventilation devices 33 are opposite, thereby realizing a spiral air flow and achieving twisting.

[0028] For a complete description of the movement law of the two ventilation devices 33 and to clearly describe how the two yarns to be butt-jointed are automatically twisted in the twisting chamber mentioned above, please refer to Appendix Figure 2 to Appendix Figure 5 .

[0029] In Appendix Figure 2 , after the previous yarn breaks away from the yarn tube supply device 2, due to the loss of tension of the yarn, the tail stock induction braking device 34 loses the support of the yarn and descends. Then the tail stock induction braking device 34 fixes the previous yarn. The ventilation device 33 corresponding to the tail stock slides to be close to the yarn tube supply device 2, and this ventilation device 33 inhales air, while the other ventilation device 33 slides to the side far from the yarn tube supply device 2 and inhales air, so that there is an overlapping area between the two yarns. The two ventilation devices 33 that inhale air make the corresponding yarn heads have false twists.

[0030] In Appendix Figure 3 , the separation device 32 descends, and then the two dispersion chambers are combined into a twisting chamber. The two ventilation devices 33 blow air respectively, so that the two yarns in the twisting chamber roll and twist.

[0031] In Appendix Figure 4 , the winding system 6 continues to wind. After the yarn obtains tension, the tail stock induction braking device 34 is lifted again, and the yarn can be smoothly conveyed.

[0032] In the attachment Figure 5 Since the two yarn tube supply devices 2 alternately clamp the yarn tubes, the ventilation device 33 that was originally close to the yarn tube supply device 2 in the attachment Figure 2 slides away from the yarn tube supply device 2, and the ventilation device 33 that was originally far from the yarn tube supply device 2 in the attachment Figure 2 slides towards the yarn tube supply device 2, making the yarn have an overlapping area again, which is convenient for re-twisting.

[0033] Specifically, the winding machine further includes a felt system 8. The felt system 8 includes a felt screw 81, a felt roller 83, a felt cover plate 84, a felt nut 85, and a felt spring 86. The felt roller 83 is rotatably installed on the felt screw 81. The felt screw 81 is installed on the frame 1. The felt nut 85 is installed on the felt screw 81 through a thread pair. The two ends of the felt spring 86 press against the frame 1 and the felt roller 83 respectively. The felt nut 85 presses the felt cover plate 84 on the felt roller 83, thereby realizing the removal of floating hairs on the yarn and the unified correction of the yarn size when the yarn bypasses the felt roller 83.

[0034] Specifically, the winding machine further includes a paraffin supply system 9. The paraffin supply system 9 includes a paraffin wheel. A paraffin installation long hole 11 is provided on the frame 1. The paraffin wheel is rotatably installed in the paraffin installation long hole 11. The yarn bypasses the paraffin wheel, so that the yarn is coated with paraffin, making the yarn delivery smooth.

[0035] 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 installed on the frame 1, and the winding guide wheel 52 is slidably installed on the winding guide rod 51, thereby realizing the adjustment of the position of the winding guide wheel 52.

[0036] 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, thereby realizing winding.

[0037] Specifically, the yarn guiding system 7 includes a yarn guiding wheel. A plurality of reciprocating guiding grooves are provided on the winding roller, realizing the reciprocating swing of the yarn.

[0038] Specifically, the tension stabilizing system 4 includes a tension swing arm 41. The tension swing arm 41 is rotatably installed 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.

[0039] Specifically, a friction rubber plate is provided on one side of the frame 1 close to the tailstock induction braking device 34 to realize the clamping of the tailstock.

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