Description
Technical Field
[0001] The utility model relates to the technical field of textiles, in particular to an air flow false twister. Background Art
[0002] There is a strong market demand for soft fabrics, which offer comfort. Currently, most fabrics on the market achieve a soft feel by adding softeners. However, softeners are chemical agents that can not only cause direct damage to human skin when worn next to the skin, but can also pollute the environment during production and waste disposal. Therefore, efforts are underway to find alternative methods for making soft fabrics through physical methods.
[0003] Fabrics are woven from yarns, and the softness of the yarns affects the softness of the fabrics to a certain extent. The hardness of the yarn is mainly affected by the properties of the original fiber material and the spinning twist coefficient. The spinning twist coefficient directly affects the softness and hardness of the yarn. The general rule is that the larger the spinning twist coefficient, the greater the fiber torque in the yarn, the tighter the wrapping, and the relatively harder the feel. Therefore, in order to obtain a softer yarn, the twist coefficient of the yarn should be reduced. However, in the process of traditional ring spinning, the reduction of the twist coefficient will cause the dynamic spinning tension to be greater than the strength of the section, which can easily cause the spinning end to break and lead to spinning difficulties.
[0004] The existing flexible spinning technology is mainly achieved by installing a dynamic false twister driven by a wheel belt at the position from the front roller to the yarn guide hook of the spinning frame. The yarn is passed through the passing channel of the dynamic false twister, which will be driven by direct physical contact with the yarn and driven by the rotating dynamic false twister to achieve false twisting. When working on the broken end joint, the operator needs to pass the yarn from one end of the passing channel and out from the other end. This operation is difficult and inefficient. In addition, the mechanical structure and power device of the existing dynamic false twister are relatively complex, which poses great difficulties and challenges for large-scale popularization and mass production in spinning.

[0015] Preferably, the side opening is located above the false twister body.
[0016] Preferably, the frame plate is fixedly arranged on one end of the connecting block, and the other end of the connecting block is fixedly connected to the false twister body.
[0017] Compared with the prior art, the utility model has achieved the following technical effects:
[0018] The air flow false twister provided by the utility model is fixedly arranged on the yarn path between the front roller and the yarn guide hook through the false twister body. The installation position is clear and the fixing method is relatively simple, which makes the installation and debugging process on the spinning equipment more convenient and does not require complicated installation steps and high-precision adjustment; the side opening is connected to the circular central channel, and when the yarn breaks, the operator can quickly introduce the broken yarn into the central channel through the side opening. Since the two ends of the side opening correspond to the two ends of the central channel one by one, the yarn introduction process is more intuitive and easy, and the operator can more easily remove the broken yarn The yarn in the center of the circular channel is aligned with the running yarn and the yarn is spliced, which improves the speed and accuracy of the splicing; the high-speed vortex airflow false-twists the yarn in the circular center channel, so that the yarn obtains temporary twist, which enhances the strength and stability of the yarn, and the uniform false twisting effect helps the yarn fiber structure to be more compact, thereby improving the quality of the yarn, and the high-speed vortex airflow can also wrap around the large hairiness on the surface of the yarn body, so that the large hairiness is spirally wrapped around the yarn surface, thereby improving the yarn dryness to a certain extent and enhancing the yarn strength; there is a distance between the yarn and the inner wall of the circular center channel to avoid direct friction between the yarn and the inner wall, reducing the yarn The wear and damage of the yarn during processing can be reduced, and the integrity and softness of the yarn can be maintained. The high-speed vortex airflow forms an air film between the yarn and the inner wall of the channel, which plays a buffering role. When the yarn moves in the central channel, the air film can reduce the collision force between the yarn and the inner wall, reduce the wear of the yarn, and help to improve the super-soft effect. The false twister body has only a few main components such as the circular central channel, side openings and air inlet holes. This simple structural design makes the manufacturing process relatively easy, reduces complex mechanical structures and parts, and reduces production difficulty and cost. It is simple to connect the broken ends of the yarn It is fast, efficient, and low-cost, and can be applied to large-scale mass production; and an air flow false twister is installed at the position from the front roller to the yarn guide hook, which can change the tension distribution of the spinning section, so that a strong twist is formed between the front roller and the air flow false twister, reducing the length of the spinning triangle area, gathering the fibers in the triangle area, increasing the fiber bundles in the triangle area and improving the bonding strength between the fibers, thereby increasing the strength of the yarn; when the yarn leaves the air flow false twister, a reverse twist will be formed between the air flow false twister and the yarn guide hook to neutralize the true twist transmitted from the balloon area, forming the characteristics of loose yarn outside and tight inside, so that the yarn appears to be better softness.
[0019] Furthermore, the gas outlet of the air inlet points to the yarn inlet of the circular central channel, so that the high-speed vortex airflow can move along the axis of the circular central channel toward the yarn inlet, that is, the air is released from the yarn inlet, and the yarn output from the circular central channel will not be affected by the additional hairiness caused by the impact of the released airflow; and if it is Z-twisted yarn, the high-speed vortex airflow there will promote the axial rotation of the yarn, increase the twist from there to the front roller jaws, reduce the length range of the twisting triangle area, and promote the inward transfer of the fiber. When the yarn passes through the false twister body, the twist is neutralized with the true twist transmitted from the yarn guide hook.
[0020] Furthermore, the V-groove of the frame plate cooperates with the jaws formed by the front roller and the front top roller to realize the suspended state of the yarn in the central axis of the circular center channel; and a frame plate is provided at one end of the false twister body close to the yarn guide hook, and the V-groove on the frame plate provides a clear guide for the yarn. When the yarn comes out of the circular center channel, it can accurately enter the V-groove and then smoothly pass through the yarn guide hook, ensuring the stability of the yarn direction throughout the entire production process and reducing production problems caused by yarn shaking or deviation.
[0021] Furthermore, there is a distance between the V-shaped groove and the end of the circular center channel, so that when the yarn comes out of the circular center channel and enters the V-shaped groove, it will not directly contact and rub with the end of the circular center channel. This can reduce the problems of yarn hairiness and wear caused by friction, maintain the surface quality and strength of the yarn, and help improve the softness and smoothness of the yarn; the existence of the distance can allow the high-speed vortex airflow in the circular center channel to continue to have a certain effect on the yarn when the yarn leaves the channel without being immediately disturbed by the V-shaped groove, which helps to maintain the stability and continuity of the airflow, make the false twist effect more lasting and uniform, and improve the false twist quality of the yarn.
[0022] Furthermore, the side opening is flared, and the opening at the end away from the circular center channel is larger, which helps the yarn to enter the circular center channel more conveniently and gently from the side opening; the flared side opening allows operators to more conveniently observe the situation inside the circular center channel when performing equipment maintenance and inspection.
[0023] Furthermore, the arcuate guide surface enables the yarn to enter the side opening more smoothly and then enter the circular central channel; the arcuate guide surface can prevent the yarn from accidentally hanging on the edge of the side opening.
[0024] Furthermore, the false twister body is divided into two parts, the base and the vortex finder, so that the functions of each part are clearer and more independent. The base is mainly responsible for the initial processing of the intake air, and the vortex finder focuses on the yarn channel (circular central channel and side opening) and the secondary processing of the intake air (forming a high-speed vortex airflow through the second air chamber and the air inlet to false twist the yarn). This modular design facilitates the division of labor and cooperation in the production process and improves production efficiency; the first air chamber plays the role of buffering and preliminary distribution of airflow. It can make the airflow entering from the main air inlet enter the second air chamber more evenly, and then the second air chamber further guides the airflow to the air inlet. This graded air chamber structure helps to optimize the distribution of the airflow, making the high-speed vortex airflow finally formed more uniform and stable.
[0025] Furthermore, the inclined mounting long hole on the fixing bracket provides a certain adjustment space for the installation of the false twister body. During the installation process, the position of the false twister body relative to the front roller seat can be fine-tuned by moving the position of the fixing bolt in the inclined mounting long hole. This is very useful for accurately adjusting the position of the false twister on the yarn path, because different yarn varieties or production processes may require the false twister to be in slightly different positions to achieve the best false twisting effect.
[0026] Furthermore, the side opening is at the top, which makes it easier to thread the yarn into the circular central channel from top to bottom.
[0027] Furthermore, connecting the frame plate and the false twister body through the connecting block can provide more stable support for the frame plate; the frame plate plays an important guiding role in the transmission process of the yarn and needs to maintain a stable position; the existence of the connecting block can disperse the external forces such as the tension from the yarn borne by the frame plate, and prevent the frame plate from shaking or displacement during operation, thereby ensuring that the yarn can accurately pass through the V-groove on the frame plate into the yarn guide hook, thereby improving the stability of yarn production.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0047] Example 1
[0048] This embodiment provides an air flow false twister 100, which is mainly used for false twisting of super soft yarn, but not limited to, Figures 1 to 7 As shown, it includes a false twister body 10; the false twister body 10 is used to be fixedly arranged on the yarn path between the front roller 40 and the yarn guide hook 60; the false twister body 10 has a circular central channel 121 running through it, and a side opening 122 is provided on the false twister body 10 that is connected to the circular central channel 121, and the two ends of the side opening 122 correspond one to one with the two ends of the circular central channel 121; the false twister body 10 is provided with an air inlet 123 for introducing high-speed gas, and the air inlet 123 is connected to the circular central channel 121, and the high-speed gas passing through the air inlet 123 can form a high-speed vortex airflow in the circular central channel 121; there is a distance between the yarn located in the circular central channel 121 and the inner wall of the circular central channel 121.
[0049] The false twister body 10 is fixedly arranged on the yarn path between the front roller 40 and the yarn guide hook 60, and the installation position is clear and the fixing method is relatively simple, which makes the installation and debugging process on the spinning equipment more convenient and does not require complicated installation steps and high-precision adjustments; the side opening 122 is connected to the circular central channel 121, and when the yarn breaks, the operator can quickly introduce the broken yarn into the central channel through the side opening 122. Since the two ends of the side opening 122 correspond to the two ends of the central channel one by one, the yarn introduction process is more intuitive and easy, and the operator can more easily align the broken yarn with the running yarn. The yarns are aligned and joined, which improves the speed and accuracy of the joining; the high-speed vortex airflow false-twists the yarn in the circular central channel 121, so that the yarn obtains temporary twist, thereby enhancing the strength and stability of the yarn, and the uniform false twisting effect helps to make the yarn fiber structure more compact, thereby improving the quality of the yarn, and the high-speed vortex airflow can also wrap around the large hairiness on the surface of the yarn body, so that the large hairiness is spirally wrapped around the yarn surface, thereby improving the yarn dryness quality to a certain extent and enhancing the yarn strength; there is a gap between the yarn and the inner wall of the circular central channel 121, which avoids direct friction between the yarn and the inner wall, thereby reducing the wear and tear of the yarn during processing. The yarn is then pulled back and forth in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not spun around and the yarn is pulled back in a direction of rotation so that the yarn is not Low, can be suitable for large-scale popularization and mass production; and an air flow false twister 100 is installed at the position from the front roller 40 to the yarn guide hook 60, which can change the tension distribution of the spinning section, so that a strong twist is formed between the front roller 40 and the air flow false twister 100, reducing the length of the spinning triangle area, gathering the fibers in the triangle area, increasing the fiber bundles in the triangle area and improving the cohesion strength between the fibers, thereby increasing the strength of the yarn; when the yarn leaves the air flow false twister 100, a reverse twist will be formed between the air flow false twister 100 and the yarn guide hook 60 to neutralize the true twist transmitted from the balloon area, forming the characteristics of the yarn being loose on the outside and tight on the inside, so that the yarn appears to have better softness.
[0050] Specifically, the air flow false twister 100 of this embodiment is arranged between the front roller 40 and the yarn guide hook 60 of the ring spinning or compact spinning machine; the yarn strips are output from between the front roller 40 and the front top roller 50, enter the circular center channel 121 of the false twister body 10, pass through the V-shaped groove 21, and finally are output through the yarn guide hook 60.
[0051] Among them, the relevant settings of the air inlet 123 are:
[0052] Among the optional solutions of this embodiment, it is more preferred that Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the end of the circular center channel 121 close to the front roller 40 is the yarn inlet, and the end of the circular center channel 121 close to the yarn guide hook 60 is the yarn outlet; the gas outlet of the air inlet 123 points to the yarn inlet of the circular center channel 121, and the high-speed vortex airflow entering the circular center channel 121 through the yarn inlet can move toward the yarn inlet along the axis of the circular center channel 121. The gas outlet of the air inlet 123 points to the yarn inlet of the circular central channel 121, so that the high-speed vortex airflow can move along the axis of the circular central channel 121 toward the yarn inlet, that is, the air is released from the yarn inlet, and the yarn output from the circular central channel 121 will not be affected by the additional hairiness caused by the impact of the released airflow; and if it is Z-twisted yarn, the high-speed vortex airflow there will promote the axial rotation of the yarn, increase the twist from there to the jaws of the front roller 40, reduce the length range of the twisting triangle, and promote the inward transfer of the fiber. When the yarn passes through the false twister body 10, the twist is neutralized with the true twist transmitted from the yarn guide hook 60.
[0053] Among them, the relevant settings of the side opening 122 are:
[0054] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 3 and Figure 5 As shown, the side opening 122 is flared, and the opening size of the end of the side opening 122 away from the circular central passage 121 is larger than the opening size of the end of the side opening 122 closer to the circular central passage 121. The flared shape of the side opening 122, with the larger opening size at the end away from the circular central passage 121, facilitates the yarn to enter the circular central passage 121 more conveniently and gently through the side opening 122. The flared side opening 122 also makes it easier for operators to observe the interior of the circular central passage 121 during equipment maintenance and inspection.
[0055] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 3 and Figure 5 As shown, the two sides of the side opening 122 are arcuate guide surfaces 124. The arcuate guide surfaces 124 can make the yarn enter the side opening 122 more smoothly and then enter the circular central channel 121; the arcuate guide surfaces 124 can prevent the yarn from accidentally hanging on the edge of the side opening 122.
[0056] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 3 and Figure 5As shown, the side opening 122 is located above the false twister body 10. The side opening 122 is at the top, which makes it easier to thread the yarn into the circular central channel 121 from top to bottom.
[0057] Among them, the relevant settings of the false twister body 10 are as follows:
[0058] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 5 As shown, the false twister body 10 includes a base 11 and a vortex finder 12; the base 11 is provided with a first air chamber 111 and a main air inlet 112 connected to the first air chamber 111; the vortex finder 12 is provided with a circular central channel 121, a side opening 122, a second air chamber 125 and an air inlet hole 123 connected to the second air chamber 125; the vortex finder 12 is used to be fixedly set on the base 11, and the first air chamber 111 is sealed and connected to the second air chamber 125. The false twister body 10 is divided into two parts, a base 11 and a vortex finder 12, so that the functions of each part are clearer and more independent. The base 11 is mainly responsible for the preliminary processing of the intake air, and the vortex finder 12 focuses on the yarn channel (the circular central channel 121 and the side opening 122) and the secondary processing of the intake air (forming a high-speed vortex airflow through the second air chamber 125 and the air inlet 123 to false twist the yarn). This modular design facilitates the division of labor and cooperation in the production process and improves production efficiency; the first air chamber 111 plays the role of buffering and preliminarily distributing the airflow. It can make the airflow entering from the main air inlet 112 enter the second air chamber 125 more evenly, and then the second air chamber 125 further guides the airflow to the air inlet 123. This graded air chamber structure helps to optimize the distribution of the airflow, so that the high-speed vortex airflow finally formed is more uniform and stable.
[0059] Specifically, the air flow is input into the air chamber cavity formed by the first air chamber 111 and the second air chamber 125 through the main air inlet 112 , and enters the circular central channel 121 through the obliquely arranged air inlet hole 123 .
[0060] Among them, about the setting of the frame plate 20 on the false twister body 10:
[0061] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 4As shown, a frame plate 20 is fixedly mounted on one end of the false twister body 10 near the yarn guide hook 60; a V-shaped groove 21 is provided on the frame plate 20, and the yarn in the circular central channel 121 passes through the V-shaped groove 21 and is then passed into the yarn guide hook 60. The V-shaped groove 21 of the frame plate 20 cooperates with the jaws formed by the front roller 40 and the front top roller 50 to maintain the yarn suspended in the central axis of the circular central channel 121. The frame plate 20 is also provided on one end of the false twister body 10 near the yarn guide hook 60. The V-shaped groove on the frame plate 20 provides a clear guide for the yarn. When the yarn emerges from the circular central channel 121, it can accurately enter the V-shaped groove and then smoothly pass into the yarn guide hook 60, ensuring that the yarn has a stable direction throughout the production process and reducing production problems caused by yarn shaking or deviation.
[0062] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 4 As shown, there is a distance between the V-shaped groove 21 and the end of the circular central channel 121. The distance between the V-shaped groove and the end of the circular central channel 121 ensures that when the yarn exits the circular central channel 121 and enters the V-shaped groove, it will not directly contact and rub against the end of the circular central channel 121. This can reduce problems such as hairiness and wear caused by friction on the yarn, maintain the surface quality and strength of the yarn, and help improve the softness and smoothness of the yarn. The existence of the distance allows the high-speed vortex airflow in the circular central channel 121 to continue to have a certain effect on the yarn when the yarn leaves the channel without being immediately disturbed by the V-shaped groove. This helps to maintain the stability and continuity of the airflow, making the false twist effect more lasting and uniform, and improving the false twist quality of the yarn.
[0063] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 4 As shown, the frame plate 20 is fixedly mounted on one end of a connecting block 22, the other end of which is fixedly connected to the false twister body 10. Connecting the frame plate 20 and the false twister body 10 via the connecting block 22 provides more stable support for the frame plate 20. The frame plate 20 plays an important guiding role in the yarn transmission process and needs to maintain a stable position. The presence of the connecting block 22 can disperse external forces such as tension from the yarn on the frame plate 20, preventing the frame plate 20 from shaking or shifting during operation, thereby ensuring that the yarn can accurately pass through the V-groove on the frame plate 20 and enter the yarn guide hook 60, thereby improving the stability of yarn production.
[0064] Among them, the relevant structure about the false twister body 10 being installed on the front roller 40 seat is as follows:
[0065] Among the optional solutions of this embodiment, it is more preferred that Figure 2As shown, the apparatus further includes a fixing bracket 30, which is fixedly mounted on the front roller 40 seat. The fixing bracket 30 has an inclined mounting slot 31, and the false twister body 10 is provided with an internally threaded hole 113. A fixing bolt is inserted through the inclined mounting slot 31, and the threaded end of the fixing bolt is threadedly connected to the internally threaded hole 113. The inclined mounting slot 31 on the fixing bracket 30 provides a certain amount of adjustment space for the installation of the false twister body 10. During installation, the position of the fixing bolt can be fine-tuned relative to the front roller 40 seat by moving the position of the fixing bolt within the inclined mounting slot 31. This is very useful for precisely adjusting the position of the false twister on the yarn path, as different yarn types or production processes may require the false twister to be in slightly different positions to achieve the optimal false twisting effect.
[0066] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
