Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes the defect management modes in the embodiments in detail with reference to the drawings in the embodiments of the present invention.
Example 1
In the textile equipment, a yarn carrier 1 for conveying fiber yarns needs to be arranged, and the fiber yarns are conveyed to a position needing to be woven through the yarn carrier 1. Various tension adjusting devices are often arranged in the yarn carrier 1, and the tension of the fiber yarns is adjusted through the tension adjusting devices, so that the fiber yarns can meet the tension requirement when moving in the spinning process.
Some of the tension adjusting devices provided in the conventional yarn carrier 1 include a tension control roller around which the fiber yarn is wound, and adjust the tension of the fiber yarn by adjusting the height of the tension control roller to stretch or relax the fiber yarn. The adjustment of the tension of the fibre yarn by means of only one tension control roller is very limited. Alternatively, the conventional yarn carrier 1 may be provided with a plurality of yarn guides on the same plane, and the tension of the fiber yarn may be adjusted by winding the fiber yarn around the plurality of yarn guides. But the adjustment of the tension of the fibre yarn is limited, since the drawing of the fibre yarn in one direction is very limited. With the progress of the textile industry, the textile equipment is developed from traditional two-dimensional plane textile to three-dimensional textile. In the three-dimensional weaving, the moving span of the fiber yarn is increased, so that the tension requirement on the fiber yarn is increased.
In view of the above problems, the present invention provides a yarn carrier 1, and a tension adjusting device disposed on the yarn carrier 1, which can expand the tension adjusting range of the fiber yarn, so that the tension of the fiber yarn can meet the requirement of three-dimensional spinning. As shown in fig. 1-3, a plurality of yarn passing wheels 2 capable of rotating around a shaft are arranged on a yarn carrier 1, rotating shafts of the plurality of yarn passing wheels 2 are respectively arranged along different directions, and fiber yarns are sequentially wound around the peripheries of at least two yarn passing wheels 2 which are combined randomly in the plurality of yarn passing wheels 2 in a transmission process; the yarn carrier 1 is also provided with a moving device which is drawn and moved by the fiber yarn, and an elastic moving structure 21 which is compressed by the moving device and adjusts the tension of the fiber yarn. When the fiber yarn is dragged, the dragging movement device moves, the moving movement device compresses the elastic movement structure 21, the compressed elastic movement structure 21 generates elastic force for restoring deformation, and the fiber yarn needs to overcome the elastic force if being continuously dragged and moved at the moment, so that the fiber yarn is stretched, and the tension of the fiber yarn is improved. In the process of winding the fiber yarns, the yarn carrier 1 is also provided with the plurality of yarn passing wheels 2, so that the fiber yarns are wound on the plurality of yarn passing wheels 2 in the moving process, and the fiber yarns are further favorably stretched by utilizing the arrangement of the yarn passing wheels 2 in the moving process. The yarn passing wheels 2 are provided with rotating shafts in different directions, and the fiber yarns are wound on the yarn passing wheels 2 with different rotating shafts in the winding process, so that the fiber yarns can be stretched in different directions. The fiber yarn is drawn along a certain direction with a limit, and the fiber yarn is wound on the wire wheel 2 with the rotating shaft along a plurality of directions, so that the fiber yarn can be drawn along a plurality of directions, the tension of the fiber yarn is improved, and the fiber yarn can obtain a higher tension adjusting range.
As shown in fig. 1 to 3, the plurality of thread passing wheels 2 include thread passing wheels 2 disposed on different sides of the yarn carrier 1, and the rotation axes of the thread passing wheels 2 are disposed in a direction perpendicular to the side where the thread passing wheels are disposed, so that the thread passing wheels 2 wound by the fiber yarns have rotation axes in different directions by being wound around the thread passing wheels 2 disposed on different sides, thereby achieving the effect of stretching the fiber yarns in different directions as described above. Any two wire passing wheels 2 which are sequentially wound by the fiber yarns according to the sequence of the transmission route in the transmission process are respectively arranged on two different side surfaces. The thread guide wheels 2 on which the fiber yarns are sequentially wound are arranged on different side surfaces, namely the fiber yarns continuously change the stretching direction in the moving process. As described above, since the fiber yarn is drawn in a certain direction during the movement, it is more likely to cause the fiber yarn to be broken when the fiber yarn is continuously drawn in the same direction. Therefore, the invention can obtain larger stretching range under the condition that the fiber yarns are not broken by pulling by continuously changing the stretching direction of the fiber yarns, thereby expanding the tension adjusting range of the fiber yarns.
As shown in fig. 1 to 3, the yarn carrier 1 includes an upper tension adjusting bracket 22 and a lower tension adjusting bracket 23, and the tension adjusting device of the present invention has a relatively simple structure and mainly includes the upper tension adjusting bracket 22 and the lower tension adjusting bracket 23. The moving device is positioned on the tension adjusting lower bracket 23 when in rest, and the elastic moving structure 21 is arranged between the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 and is in limited contact with the tension adjusting upper bracket 22. Part of the yarn passing wheel 2 is fixed on the moving device, and part of the fiber yarns on the yarn passing wheel 2 draw the moving device to move. After the fiber yarn starts to be dragged and moved, the fiber yarn on a part of the wire passing wheel 2 arranged on the moving device is dragged and moved, and then the moving device is driven to move. The moving device is arranged on the tension adjusting lower bracket 23, and the elastic moving structure 21 is arranged between the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23, and once the moving device starts to move in a traction manner, the moving device compresses the elastic moving structure 21 on the moving device. The elastic moving structure 21 is limited by the tension adjusting upper bracket 22, so that the elastic moving structure 21 is compressed, and the elastic moving structure 21 generates an elastic force, and the fiber yarn can improve the tension of the fiber yarn by using the elastic force as described in the above paragraph. And the specific arrangement of the wire passing wheels 2, as shown in fig. 1-3, at least one wire passing wheel 2 is arranged on the tension adjusting upper bracket 22, the wire passing wheels 2 fixed on the exercise device are respectively positioned on different sides of the tension adjusting lower bracket 23, and the wire passing wheel 2 arranged on the tension adjusting upper bracket 22 is positioned on the other side different from the different sides. Due to the arrangement, the yarn passing wheels 2 are respectively arranged on different side surfaces, so that the directions of the rotating shafts of the yarn passing wheels 2 are different, and the fiber yarns are stretched in different directions. Wherein the moving means comprises a moving bar 24 for drawing and moving the fiber yarn, it is also possible to arrange the moving means in other forms of structures, such as a moving roller, as long as the moving means is capable of moving in the drawing direction of the fiber yarn. The movable rod 24 is connected with the elastic movable structure 21. The specific structure of the elastic moving structure 21 is: the elastic moving structure 21 includes a link 25 and a spring 26, and the link 25 is connected to the moving rod 24. As shown in particular in fig. 1-3, two parallel links 25 are provided on the travel bar 24. The connecting rod 25 extends in the direction of movement of the shift rod 24, and will move the pull rod 25 thereon during the pulling movement of the shift rod 24 by the fiber yarn. The end of the link 25 remote from the displacement rod 24 is connected to a spring 26, i.e. the link 25 will during displacement compress the spring 26 at its end, where the spring 26 may also be provided as another elastic element. An end of the spring 26 remote from the link 25 abuts against a bottom of the tension-adjusting upper bracket 22. The spring 26 is pressed by the connecting rod 25 due to the contact of one end of the spring 26 with the tension adjusting upper bracket 22, so that the spring 26 generates elastic force, and the process of increasing the tension of the fiber yarn occurs. In order to ensure that the connecting rod 25 moves according to the traction direction of the fiber yarns in the moving process, the tension adjusting lower bracket 23 is provided with a limiting pipe 27, and the connecting rod 25 is embedded in the limiting pipe 27; the path of travel of the linkage 25 is further defined by a limit tube 27.
As shown in fig. 1 to 3, a first outlet hole 18 for guiding the fiber yarn is formed in the tension adjusting upper bracket 22, and a second outlet hole 20 for allowing the fiber yarn to pass through is formed at the top end of the tension adjusting upper bracket 22. The fiber yarn enters the tension adjusting device for tension adjustment through a first outlet hole 18 arranged in the middle of an upper tension adjusting bracket 22, and finally passes out of the tension adjusting device through a second outlet hole 20 arranged at the top of the upper tension adjusting bracket 22. The second outlet hole 20 is reasonably arranged, and the second outlet hole 20 is directly arranged at the top end of the tension adjusting upper bracket 22 because the fiber yarn is finally moved to the top of the tension adjusting device for later weaving. And in the middle, in order to ensure that the running of the fiber yarn moves according to a set route, a threading hole 19 for the fiber yarn to pass through is arranged on the tension adjusting lower bracket 23.
The positions of the thread passing wheels 2 on the yarn carrier 1 are distributed as follows: the front surface 10 of the tension adjusting upper bracket 22 is provided with a plurality of wire passing wheels 2, the middle part of the tension adjusting upper bracket 22 is provided with a first wire outlet hole 18, a second wire passing wheel 15 is arranged around the first wire outlet hole, and the top end of the tension adjusting upper bracket 22 is provided with a fourth wire passing wheel 14 around a second wire outlet hole 20. The two ends of the movable rod 25 are respectively provided with the wire wheel 2 on the surfaces parallel to the left side surface 11 and the right side surface 12 of the tension adjusting lower bracket 23. Specifically, the third yarn guide wheel 16 is disposed on the left side surface 11 of the moving rod 25, and the first yarn guide wheel 17 is disposed on the right side surface 12 of the moving rod 25.
Specifically, as shown in fig. 4 to 6, the wire passing wheel 2 includes a hub 3 shaped like a cylinder, and a fiber yarn is wound on an outer circumference of the hub 3; the middle part of wheel hub 3 sets up hollow, cylindrical groove 4 that the axial runs through wheel hub 3, and cylindrical groove 4 embeds bearing 5. That is, the wire passing wheel 2 consists of a wheel hub 3 and a bearing 5, and the bearing 5 is embedded in the middle of the wheel hub 3, so that the wheel hub 3 can rotate along with the bearing 5. The position of the yarn carrier 1 on which the yarn wheel 2 is arranged is provided with an installation shaft, and the bearing 5 is matched with the installation shaft and fixes the yarn wheel 2. The thread wheel 2 is fixed on the thread carrier 1 through the bearing 5, and the hub 3 can rotate along with the bearing 5 due to the matching of the bearing 5 and the hub 3.
As shown in fig. 4 to 6, the hub 3 is provided at the middle in the axial direction with a bobbin 6 having a cylindrical outer periphery, and the fiber yarn is wound around the bobbin 6; the two ends of the hub 3 along the axial direction form conical guide structures 7 respectively, and the circular section of each guide structure 7 is gradually reduced from the two axial end surfaces 8 of the hub 3 to the inside along the axial direction. That is, at both ends of the hub 3 in the axial direction, guide structures 7 are respectively provided, the sectional area of which is gradually reduced from the end face of the hub 3 to the inside. Because the circular cross-sectional area of the winding shaft 6 in the middle is smaller, the circular cross-sectional areas of the guide structures 7 at the two axial ends of the hub 3 are larger, and the areas of the circular cross-sectional areas of the guide structures 7 are continuously enlarged towards the two ends along the axial direction, the structure enables the fiber yarns wound on the winding shaft 6 to be difficult to slide off the winding shaft 6, and once the fiber yarns are wound on the winding shaft 6, the fiber yarns are easy to be kept on the winding shaft 6.
As shown in fig. 1 to 3, the yarn carrier 1 includes a bobbin 9 for transporting a fiber yarn, a tension adjusting upper bracket 22 and a tension adjusting lower bracket 23 for adjusting tension of the fiber yarn are provided outside the bobbin 9, both the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 are parallel to the extending direction of the bobbin 9, and the fiber yarn is transported from the bobbin 9 to the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 and is wound around the yarn wheel 2. By arranging the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 at positions close to the bobbin 9, the fiber yarn is conveniently directly transferred from the bobbin 9 to the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23. And the top end of the tension adjusting upper bracket 22 and the bottom end of the tension adjusting lower bracket 23 are respectively connected with the bobbin 9, so that the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 are supported through connection, and the strength of the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 is improved.
The fiber yarn is enclosed into a cheese, the yarn is usually knitted by the cheese, and the bottom of the tension adjusting lower bracket 23 is connected with an unwinding tension bracket 13 which supports the cheese and controls the cheese to unwind the fiber yarn. The unwinding tension frame 13 is arranged, so that the fiber yarn is directly unwound from the cheese to form a root-shaped fiber yarn which can be braided. An unwinding tension bracket 13 is positioned at the bottom of the bobbin 9, and the fiber yarn unwound from the bobbin is transported along the bobbin 9 to a tension-adjusting upper bracket 22 and a tension-adjusting lower bracket 23.

The reason why the thread passing wheels 3 need to be arranged on different planes has been discussed previously, and the reason why any two thread passing wheels 3, which need to be sequentially wound during the transfer of the fiber yarn, need to be arranged on different planes, is also discussed. Therefore, in the process of transmitting the fiber yarn on the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23, any two yarn guide wheels 3 which are sequentially wound are respectively arranged on any two different planes of the front 10, the left side 11 and the right side 12. Therefore, the fiber yarns can be stretched in a plurality of different directions, and the tension of the fiber yarns is improved along different directions.
The fiber yarn is enclosed into a cheese, the cheese is usually used for spinning, the fiber yarn on the cheese is unwound by using a mechanical structure during spinning, so that the cheese is unwound into the fiber yarn, and the unwound fiber yarn is used for spinning. As shown in fig. 2 and 3, the tension adjusting device includes an unwinding tension bracket 13 which supports the cheese and controls the cheese to unwind the fiber yarn, the unwinding tension bracket 13 is located at the bottom of the bobbin 9, the unwound fiber yarn is first transferred from the unwinding tension bracket 13 to the bobbin 9, and the fiber yarn is further transferred along the bobbin 9 to the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23. The front surfaces 10 of the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 are parallel to the outer tangent surface of the bobbin 9 along the extending direction of the bobbin 9, the left side surface 11 is positioned on the left side of the unwinding tension frame 13, and the right side surface 12 is positioned on the right side of the unwinding tension frame 13. The tension adjusting lower support 23 surrounds the bobbin 9 from one side surface of the bobbin 9, so that the bobbin 9 is close to the tension adjusting lower support 23, the whole structure is compact, and the movement of fiber yarns is facilitated.
As shown in fig. 1 to 3, a first outlet hole 18 for guiding a fiber yarn is provided in the middle of the front surface 10 of the tension adjusting upper bracket 22, and the fiber yarn is threaded into the tension adjusting upper bracket 22 through the first outlet hole 18. The lower end of the front surface 10 of the tension adjusting lower bracket 23 is provided with a threading hole 19 for guiding the fiber yarn to pass through. The arrangement of the threading holes 19 is significant in that, because the fiber yarns move far, the threading holes 19, which are holes for guiding the movement of the fiber yarns, need to be arranged outside the holes for leading in the fiber yarns and the holes for leading out the fiber yarns. The top end of the tension adjusting upper bracket 22 is provided with a second outlet hole 20 for leading the fiber yarn to pass through. Since the spinning device is often arranged on top of the bobbin 9, eventually requiring the fibre yarn to be guided to the top, a second outlet hole 20 for the fibre yarn is arranged on top of the tension-adjusting upper support 22.
The four wire passing wheels are arranged at the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23 at the following positions: the front 10 of the upper tension adjusting bracket 22 is provided with a fourth wire passing wheel 14 at a position close to the second appearance hole 20 at the top end, the middle part of the front 10 is provided with a second wire outgoing wheel 16 at a position close to the first appearance hole 18, and the left side 11 and the right side 12 of the bottom of the lower tension adjusting bracket 23 are respectively provided with a third wire passing wheel 16 and a first wire passing wheel 17 at positions close to the wire passing hole 19.
The specific structure of the yarn carrier 1 provided by this embodiment includes the bobbin 9, the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23, the structural arrangement of each part is relatively compact, and the structural design of each part is relatively reasonable, so that the fiber yarn can be reasonably transmitted on the yarn carrier 1 and the tension of the fiber yarn can be effectively improved.
Example 3
The present embodiment provides a specific route for the transport of 12K carbon fibers on a yarn carrier 1 of type D40 on the basis of the above-described embodiment. The 12K carbon fiber firstly enters the bobbin 9, then the bobbin 9 penetrates the tension adjusting upper bracket 22 through the first wire outlet hole 18, and the 12K carbon fiber passing through the first wire outlet hole 18 is sequentially wound on the first wire passing wheel 17 and the second wire passing wheel 15. Because the first wire passing wheel 17 is arranged on the right side surface 12, and the second wire passing wheel 15 is arranged on the front surface 10, 12K carbon fibers sequentially wound around the first wire passing wheel 17 and the second wire passing wheel 15 are respectively stretched differently along two different planes, so that the tension of the 12K carbon fibers is improved. The 12K carbon fibers wound around the second threading wheel 15 pass through the threading hole (19), and the 12K carbon fibers passing through the threading hole (19) are sequentially wound around the third threading wheel 16 and the fourth threading wheel 14. Similarly, since the third wire passing wheel 16 is disposed on the left side surface 11 and the fourth wire passing wheel 14 is disposed on the front surface 10, that is, the wire passing wheels 3 disposed on two different planes are used to stretch the 12K carbon fiber in different directions, thereby further improving the tension of the 12K carbon fiber. The carbon fiber passing through the 12K of the fourth wire guiding wheel 14 passes through the second wire outlet hole 20 and out of the tension adjusting upper bracket 22. The moving route of the 12K carbon fiber on the yarn carrier 1 provided by the embodiment enables the 12K carbon fiber to obtain a large range of tension lifting.
Through tests, when 12K carbon fiber is also moved on the yarn carrier 1 with model D40, if no yarn passing wheel 3 is wound, 12K carbon fiber enters the tension adjusting upper bracket 22 through the first wire outlet hole 18, and 12K carbon fiber is guided to pass through the threading hole 19, passes through the threading hole 19, and then passes through the tension adjusting upper bracket 22 through the second wire outlet hole 20. When the 12K carbon fiber does not pass through the yarn guide wheel 2 on the tension adjusting bracket 20, the yarn storage amount of the 12K carbon fiber is 7CM, and the carbon fiber is seriously sanded through visual observation. And the 12K carbon fiber provided by the embodiment passes through the moving route of the yarn guide wheel 2 on the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23, so that the yarn storage amount of the 12K carbon fiber is 21.5CM, and the carbon fiber is basically not sanded by visual observation.
The fact that the plurality of wire passing wheels 2 and the 12K carbon fibers are wound on the yarn carrier 1 can be proved, the tension range of the 12K carbon fibers is obviously improved through the arrangement of the wire passing wheels 2, and the structural design of the wire passing wheels 2 and the moving route of the 12K carbon fibers on the yarn carrier 1 can be effectively improved.
Example 4
The present embodiment provides a specific route for the transport of 6K carbon fibers on a yarn carrier 1 of type D40 on the basis of the above-described embodiment. The 6K carbon fiber firstly enters the bobbin 9, then enters the tension adjusting upper bracket 22 through the first wire outlet hole 18 of the bobbin 9, firstly goes to the threading hole 19 on the tension adjusting lower bracket 23 and passes through the threading hole, and then the 6K carbon fiber passing through the threading hole 19 is sequentially wound on the second threading wheel 15, the third threading wheel 16 and the fourth threading wheel 14. Since the second thread guiding wheel 15 is disposed on the front face 10, the third thread guiding wheel 16 is disposed on the left side face 11, and the fourth thread guiding wheel is disposed on the front face 10. That is, when the 6K carbon fiber moves on the tension adjusting bracket 10, the carbon fiber is firstly wound around the wire wheel 2 along the direction of the front surface 10 and is stretched along the circumference of the front surface 10; then the wire wheel 2 is wound along the direction of the left side surface 11, and the drawing is carried out along the circumference of the left side surface 11; finally, the front surface 10 is returned to and stretched in the direction of the front surface 10. The 6K carbon fiber is stretched in different directions to increase the tension, and the 6K carbon fiber is prevented from reaching the stretching limit in a certain direction and being pulled apart due to the fact that the carbon fiber is stretched in a certain direction all the time. The 6K carbon fiber finally wound around the fourth wire wheel 14 passes through the tension adjusting upper bracket 22 from the second wire outlet hole 20. The moving route of the 6K carbon fiber on the yarn carrier 1 provided by the embodiment enables the 6K carbon fiber to obtain a large range of tension lifting.
Through tests, when the 6K carbon fiber also moves on the yarn carrier 1 with the model number D40, if any yarn passing wheel 2 is not wound, the 6K carbon fiber enters the tension adjusting upper bracket 22 through the first wire outlet hole 18, and then the 6K carbon fiber is guided to pass through the threading hole 19, passes through the threading hole 19 and then passes out of the tension adjusting upper bracket 22 through the second wire outlet hole 20. When the 6K carbon fiber does not pass through the yarn guide wheel 2 on the tension adjustment upper bracket 22 and the tension adjustment lower bracket 23, the yarn storage amount of the 6K carbon fiber is 7CM, and the carbon fiber is seriously sanded through visual observation. And the 6K carbon fiber provided by the embodiment passes through the moving route of the yarn guide wheel 2 on the tension adjusting upper bracket 22 and the tension adjusting lower bracket 23, so that the yarn storage amount of the 6K carbon fiber is 15CM, and the carbon fiber is basically not sanded by visual observation.
Can prove through set up a plurality of carbon fiber winding of crossing line wheel 2, 6K on carrying yarn ware 1 and cross line wheel 2, make 6K's carbon fiber obviously improve the tension scope through the setting of crossing line wheel 2, prove promptly that the structural design of crossing line wheel 2, the carbon fiber of 6K can effectively improve the tension scope on carrying yarn ware 1.
