Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to an air flow false twister. Background Art

[0002] There is a strong demand for soft fabrics in the market. Soft fabrics have comfortable wearing performance. At present, most fabrics on the market have a soft feel by adding softeners, but softeners are chemical reagents. For some fabrics worn next to the body, they will not only cause direct damage to human skin, but also pollute the environment during production and waste clothing treatment. Therefore, we try to find other ways to make 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, the spinning twist coefficient, and other aspects. 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 softer yarns, 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 is easy to cause spinning ends to break, resulting in 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 is required 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.

[0010] Preferably, there is a distance between the V-shaped groove and the end of the circular central channel.

[0011] Preferably, the side opening is in a flared shape, and the opening size of one end of the side opening away from the circular center channel is larger than the opening size of one end of the side opening close to the circular center channel.

[0014] Preferably, it also includes a fixing bracket, which is used to be fixed on the front roller seat; the fixing bracket has an inclined mounting long hole, and the false twister body is provided with an internal threaded hole; a fixing bolt is passed through the inclined mounting long hole, and the threaded end of the fixing bolt is threadedly connected in the internal threaded hole.

[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 present invention has achieved the following technical effects:

[0018] The air flow false twister provided by the present invention 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 with 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 introduce the broken yarn The high-speed vortex airflow aligns the yarn with the running yarn and performs the joint, which improves the speed and accuracy of the joint; the high-speed vortex airflow performs false twist on the yarn in the circular center channel, so that the yarn obtains temporary twist, enhances the strength and stability of the yarn, and the uniform false twisting effect helps the yarn fiber structure to be more compact, improves the quality of the yarn, and the high-speed vortex airflow can also wrap the large hairiness on the surface of the yarn body, so that the large hairiness is spirally wrapped on the surface of the yarn, thereby improving the yarn dryness quality 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, and reduce the yarn in The wear and damage during the processing process can maintain the integrity and softness of the yarn. The high-speed vortex airflow forms an air film between the yarn and the inner wall of the channel to play 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 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; the yarn break joint work is simple and The invention is fast, efficient and low-cost, and can be applied to large-scale mass production. 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, and the length of the spinning triangle area is reduced, the fibers in the triangle area are gathered, the fiber bundles in the triangle area are increased, and the bonding strength between the fibers is increased, thereby increasing the strength of the yarn. When the yarn leaves the air flow false twister, a reverse twist is 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 surface has better softness.

[0019] Furthermore, the gas outlet of the air inlet points to the yarn inlet of the circular center channel, so that the high-speed vortex airflow can move toward the yarn inlet along the axis of the circular center channel, that is, the air is released from the yarn inlet, and the yarn output from the circular center channel will not be impacted by the released airflow and cause additional hairiness; and if it is Z-twisted yarn, the high-speed vortex airflow there will promote the axial rotation of the yarn, enhance 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 upper roller to realize the suspended holding state of the yarn on the central axis of the circular center channel; and a frame plate is arranged 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, thereby ensuring the stable direction of the yarn throughout the production process and reducing production problems caused by yarn shaking or deviation.

[0021] Furthermore, there is a spacing 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 spacing allows 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 size 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 the operator to more conveniently observe the situation inside the circular center channel when performing equipment maintenance and inspection.

[0023] Furthermore, the arc-shaped guide surface enables the yarn to enter the side opening more smoothly and then enter the circular central channel; the arc-shaped 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, a base and a 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 falsely 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 a role in buffering and preliminarily distributing the airflow. It can make the airflow entering from the main air inlet more evenly enter the second air chamber, 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, so that the high-speed vortex airflow finally formed is more uniform and stable.

[0025] Furthermore, the inclined mounting long hole on the fixed 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 twist 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, the frame plate and the false twister body are connected by a connecting block, which can provide a 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 shifting during operation, thereby ensuring that the yarn can accurately enter the yarn guide hook through the V-groove on the frame plate, thereby improving the stability of yarn production.

[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 center channel 121, and when the yarn breaks, the operator can quickly introduce the broken yarn into the center channel through the side opening 122. Since the two ends of the side opening 122 correspond to the two ends of the center 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 jointed, thereby improving the speed and accuracy of the joints; the high-speed vortex airflow performs false twisting on 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 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 quality to a certain extent and enhancing the yarn strength; there is a distance between the yarn and the inner wall of the circular central channel 121, thereby avoiding direct friction between the yarn and the inner wall, thereby reducing the wear and tear of the yarn during processing and The yarn is prevented from being damaged and the integrity and softness of the yarn are maintained. The high-speed vortex airflow forms an air film between the yarn and the inner wall of the channel to play 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 degree of the yarn, and help to improve the super-soft effect. The false twister body 10 has only a few main components such as the circular central channel 121, the side opening 122 and the air inlet 123. This simple structural design makes the manufacturing process relatively easy, reduces complex mechanical structures and parts, and reduces the production difficulty and cost. The broken end joint work of the yarn is simple and fast, with high efficiency and low cost. The yarn has a low twist rate and can be applied to large-scale 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, the length of the spinning triangle area is reduced, the fibers in the triangle area are gathered, the fiber bundles in the triangle area are increased, and the bonding strength between the fibers is increased, thereby increasing the strength of the yarn; when the yarn leaves the air flow false twister 100, a reverse twist is 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 has a better apparent 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 strands 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 are finally output through the yarn guide hook 60.

The gas outlet of the air inlet 123 points to the yarn inlet of the circular center channel 121, so that the high-speed vortex airflow can move toward the yarn inlet along the axis of the circular center channel 121, that is, the air is released from the yarn inlet, and the yarn output from the circular center channel 121 will not be affected by the impact of the released airflow and cause additional hairiness; 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 area, 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.

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, which 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.
