Description

Technical Field

[0001] This invention relates to the field of vortex spinning slub yarn technology, and in particular to a vortex spinning slub yarn spinning device with switchable slub style. Background Technology

[0002] Vortex spinning technology, with its advantages of high speed, high quality, and low hairiness, has become an important development direction in the modern spinning industry. Among these, slub yarn, as a unique fancy yarn, can give fabrics a natural and three-dimensional appearance through variations in thickness, resulting in widespread market demand. Currently, most vortex spinning slub yarn devices on the market rely mainly on a single front roller speed control to generate slubs, limiting the variation in slub style and making it difficult to achieve rapid and diverse switching of style parameters (such as slub morphology and slub length distribution).

[0003] Traditional spinning devices lack the ability to dynamically control the vortex field during slub yarn generation, making it difficult to actively and precisely intervene in the distribution and wrapping of fibers in the yarn forming area. This results in limited slub yarn morphology and poor controllability, failing to meet the demands of flexible production with small batches, multiple varieties, and high added value. Therefore, there is an urgent need for a vortex spinning slub yarn spinning device that can flexibly switch slub yarn styles and actively intervene in the yarn forming process from multiple dimensions. We propose a vortex spinning slub yarn spinning device with switchable slub yarn styles. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves highly adjustable slub yarn style and significantly improved yarn quality by integrating multiple collaborative control mechanisms, including electronic speed change, airflow assistance, and intelligent temperature control mechanical adjustment. Its core lies in breaking the limitations of the traditional single speed change mode and constructing a dynamically responsive, multi-parameter coupled intelligent spinning environment. The device can not only achieve rapid programming and switching of basic slub parameters through the precision servo drive of the traction roller group, generating diverse styles from regular to random, but also actively intervene in the spinning vortex field and fiber movement trajectory through innovative airflow disturbance and temperature control self-regulation mechanism, thereby shaping the slub shape at the microscopic level. This achieves a leap from passive formation to active shaping, expanding the design space and added value of slub yarn, while ensuring production stability and efficiency.

[0014] 2. This invention achieves highly flexible and intelligent switching of bamboo joint style by setting up a traction mechanism and a spinning mechanism. The high-response servo traction system driven by an independent control cabinet can accurately and quickly execute complex speed change curves. With the help of preset algorithms, it can generate a variety of bamboo joint styles such as equal pitch, gradient, random and even biomimetic patterns with one click. It responds quickly, has high production changeover efficiency, and perfectly adapts to the needs of flexible production.

[0015] 3. This invention introduces an active airflow disturbance mechanism by setting up a guide cavity and its internal peripheral components, thereby enhancing the expressiveness and style diversity of thick sections. Air is supplied to the guide cavity through a second air pipe, driving the spindle frame to rotate and applying controllable centrifugal disturbance to the fed fiber flow. This design breaks the limitations of the traditional static vortex field, making the fiber distribution more uneven before entering the twisting zone, thus actively generating special thick sections with more exaggerated shapes and stronger three-dimensionality, enriching the product range of slub yarn.

[0016] 4. This invention achieves dynamic and precise control of the eddy current field by setting a first temperature-sensing spring and its surrounding components. Utilizing the characteristic of the shape memory alloy temperature-sensing spring changing with the gas supply temperature, it automatically adjusts the opening of the exhaust groove and the state of the auxiliary combing mechanism. It can adaptively and finely adjust the eddy current intensity and fiber combing force in the spinning chamber according to process requirements or environmental changes, making the formation process of bamboo joints more stable and controllable, and improving the regularity and consistency of bamboo joint morphology. It has obvious advantages, especially when dealing with different raw materials or producing high-precision style bamboo joints.

[0017] 5. This invention incorporates an auxiliary module. This module passively rotates in response to the magnitude of the main vortex via its internal second fan blade. Simultaneously, it utilizes a second temperature-sensitive spring made of shape memory alloy to sense changes in airflow temperature, thereby precisely driving the displacement of the mating block and ultimately controlling the swing angle and position of the hinged mating rod. When the process is set to high temperature and large vortex to generate coarse sections, the module automatically brings the mating rod closer to the fiber flow and combs it at a matching higher speed. This helps to directionally aggregate and bind the fibers in the coarse sections, preventing fiber disorder from causing a loose and easily broken structure. Conversely, when generating fine sections at low temperature and small vortex, the mating rod automatically retracts, reducing intervention, avoiding damage to the delicate structure, and improving the regularity and style of the bamboo joint shape.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figure 1 and Figure 2As shown, a vortex spinning device for slub yarn with switchable slub style includes a front-end control cabinet 1 and a rear-end control cabinet 2. The front-end and rear-end control cabinets 1 and 2 are positioned at the front and rear ends of the device, respectively. They integrate control, power supply, and detection modules. A track 3 is provided on the side of both the front-end and rear-end control cabinets 1 and 2. The track 3 consists of a conveying end and a slide rail. A material-picking component 31 is slidably mounted on the side of the slide rail of the track 3. Another set of slide rods is provided between the front-end and rear-end control cabinets 1 and 2. The material-picking component 31 is slidably mounted on the side of the slide rods and consists of a robotic arm and control and power supply modules. An independent control cabinet 4 is equidistantly positioned between the front-end and rear-end control cabinets 1 and 2. The independent control cabinet 4 integrates control, power supply, and drive modules. An antistatic component 5 and a winding component 6 are fixedly mounted on the side of the independent control cabinet 4. A traction mechanism 7 is located above the antistatic component 5, which guides and supplies air to the fiber sliver. The spinning mechanism 8 is located on the side of the traction mechanism 7. The spinning mechanism 8 can perform vortex spinning on the fiber sliver and can switch the spinning effect in real time according to the needs. Specifically, the front-end control cabinet 1 and the rear-end control cabinet 2 drive and detect each group of independent control cabinets 4 as a whole. The independent control cabinets 4 independently control the corresponding antistatic component 5, winding component 6 and traction mechanism 7 to operate. The traction mechanism 7 first guides the fiber sliver, and then the spinning mechanism 8 performs vortex spinning on the fiber sliver. The finished slub yarn is pulled by the antistatic component 5. The antistatic component 5 has a component on its side so that the slub yarn is pulled and rotated on its side to remove static electricity. Then the finished slub yarn is wound by the winding component 6. After winding, the material picking component 31 moves to the corresponding position on the side of the track 3. The various components of the material picking component 31 place the wound yarn roll on the side of the track 3 conveyor line for conveying. After picking up the material, the winding component 6 can start a new winding action.

[0022] like Figures 2 to 4As shown, the traction mechanism 7 includes a control module 71, which is fixedly mounted on the side of the independent control cabinet 4. The control module 71 integrates a control and power supply module, which is connected to the control and power supply module circuit inside the independent control cabinet 4. A drive group 72 is fixedly mounted on the side of the control module 71, which integrates multiple drive ends. A traction roller group 73 is mounted on the side of the drive group 72, and the traction roller group 73 is correspondingly connected to the drive end side of the drive group 72. The traction roller group 73 consists of cylindrical rollers of various specifications and types. A guide cylinder 74 is fixedly mounted on the side of the control module 71 at the position corresponding to the traction roller group 73. The guide cylinder 74 is a hollow funnel cylinder. An air supply module 75 is fixedly mounted on the side of the control module 71. The air supply module 75 integrates temperature and air supply components and is connected to the power supply module inside the control module 71 for power supply. Specifically, the fiber strip is guided through the guide cylinder 74 and then conveyed by the constraint between the traction roller groups 73, thereby controlling the conveying speed of the fiber strip.

[0023] like Figures 3 to 8As shown, the spinning mechanism 8 includes a spinning tube 81, which is fixedly mounted on the side of the control module 71 by a bracket. The spinning tube 81 is a hollow cylindrical frame. A traction rod 811 is fixedly installed at the upper center of the spinning tube 81 and extends through into the interior of the spinning tube 81. The traction rod 811 is a cylindrical rod with a tapered side. A feed groove 812 penetrating into the interior is opened on the upper side of the spinning tube 81. The feed groove 812 is a rectangular groove. A discharge groove 813 penetrating into the interior is opened at the lower center of the spinning tube 81. The discharge groove 813 is a funnel-shaped cylindrical groove. A spindle frame 82 is installed inside the spinning tube 81. The traction rod 811 extends into the spindle frame 82. The spindle frame 82 is a cylindrical frame with a central cylindrical air chamber. A first air pipe is fixedly connected to the side of the air supply module 75 and is fixedly connected to the upper side of the spinning bobbin 81. The first air pipe penetrates into the interior of the spinning bobbin 81. A guide cavity 83 is formed in the bottom wall of the inner interior of the spinning bobbin 81. The guide cavity 83 is an L-shaped annular groove. A constraint frame 832 is rotatably installed inside the guide cavity 83 and is fixedly installed on the lower side of the spindle frame 82. The constraint frame 832 is an L-shaped rubber annular frame. A second air chamber is fixedly installed in a circumferential array at equal intervals on the side of the constraint frame 832. A blade 833 has a guide groove 831 that runs through the spinning bobbin 81 and is mirror-imageed on the wall of the guide cavity 83. A second air pipe is fixedly connected to the side of the air supply module 75 and is also fixedly connected to the inside of one set of guide grooves 831. A one-way valve 84 is fixedly installed inside the other set of guide grooves 831. Specifically, the fiber sliver pulled by the traction mechanism 7 enters the spinning bobbin 81 through the feed groove 812. At this time, the first air pipe is open, the second air pipe is closed, and the spindle frame 82 is damped by the constraint frame 832 and does not rotate inside the spinning bobbin 81. The gas output from the first air pipe causes vortex gas to be generated inside the spinning bobbin 81, and the fiber sliver is guided at the traction rod 811. The fiber strip is drawn in by the high-speed rotating airflow and twisted into yarn, forming a spiral base yarn. In addition, the fiber strip is subjected to the centrifugal force of the air vortex in the spinning cylinder 81. After being swung, it is drawn in by the airflow and blown by the airflow to wrap around the side of the base yarn to form a slub. This completes the normal generation of slub yarn. When it is necessary to change the slub style, it is only necessary to change the conveying traction speed of the traction mechanism 7. When the fiber strip accelerates and increases instantaneously, the excess fiber is drawn into the vortex tube. Since it cannot be completely and evenly wrapped, it will form a segment with a thicker diameter and a relatively loose structure, that is, a thick slub segment. Conversely, when the fiber strip decelerates instantaneously and the amount of fiber fed decreases sharply, it will form a slub detail that is even finer than the base yarn. In addition, in this technical solution, gas is delivered through the second air pipe, which blows the first fan blade 833, causing the first fan blade 833 to drive the constraint frame 832 to rotate. The spindle frame 82 can then rotate. In this way, the fiber strips fed into the side of the spindle frame 82 will be flung out by the spindle frame 82, causing more fiber strips to be flung out, thus generating bamboo joints with a more exaggerated style (such as giant thick joints). The inner sidewall of the spinning bobbin 81 has a through-hole exhaust groove 85. The exhaust groove 85 is a funnel-shaped cylindrical cavity. A movable frame 851 is threaded onto the port of the exhaust groove 85. The movable frame 851 is a circular block with fan-shaped grooves evenly spaced on its side. A movable block 852 is provided on the side of the movable frame 851 and slides against the wall of the exhaust groove 85. The movable block 852 is a frustum block with protrusions evenly spaced on its side. A first temperature-sensing spring 853 is fixedly connected between the sides of the movable frame 851 and the movable block 852. The first temperature-sensing spring 853 is a spring made of shape memory alloy metal (nickel-based alloy, copper-based alloy, and iron-based alloy, etc.) and deforms under the influence of temperature. Specifically, the air supply module 75 passes through the first... A gas pipe supplies gas to the inside of the spinning bobbin 81. The temperature component inside the synchronous gas supply module 75 can control the gas temperature. By changing the gas temperature, the gas inside the spinning bobbin 81 is discharged from the exhaust groove 85. At this time, the first temperature sensing spring 853 is synchronized with the gas temperature and produces a corresponding deformation. When the temperature rises, the first temperature sensing spring 853 pushes the movable block 852 to change the cross-section of the exhaust channel, and a larger vortex is generated inside the spinning bobbin 81. Conversely, when the temperature drops, the first temperature sensing spring 853 pulls the movable block 852 to change the cross-section of the exhaust channel, and a smaller vortex is generated inside the spinning bobbin 81. By changing the size of the vortex, the amplitude of the fiber sliver swing can be changed, affecting the effect of slub formation.

[0024] like Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, an auxiliary module 9 is provided inside the spinning bobbin 81. The auxiliary module 9 can assist in manipulating the yarn to make it swing more evenly. The auxiliary module 9 includes a mating cavity 91, which is located on the inner wall of the spinning bobbin 81. The mating cavity 91 is a cylindrical cavity with an I-shaped cross-section. A mating frame 92 is rotatably installed inside the mating cavity 91. The mating frame 92 is a hollow "T"-shaped cylindrical frame. Openings 921, which are circular holes, are equidistantly arranged in a circular array on the side of the mating frame 92. A series of fixedly installed components are also arranged in a circular array on the side of the mating frame 92. The second fan blade 922 is attached to the wall of the mating cavity 91. Mounting slots 93 are equidistantly arranged in a circular array on the upper side of the mating frame 92. The mounting slots 93 are rectangular. A mating rod 94 is installed inside the mounting slot 93 and is rotatably mounted on the wall of the mounting slot 93 via a cylindrical rod. The mating rod 94 is a folded cylindrical rod, corresponding to the side of the spindle frame 82. A support block 95 is fixedly connected between the wall of the mounting slot 93 and the side of the second temperature-sensing spring 97. The support block 95 is a corrugated rectangular sheet of elastic material and is movable inside the mating frame 92. A mating block 96 is provided, and the mating block 96 corresponds to the lower side of the mating rod 94. The mating block 96 is a convex-shaped round block. A second temperature-sensing spring 97 is fixedly connected between the lower side of the mating block 96 and the inner bottom wall of the mating frame 92. The second temperature-sensing spring 97 and the mounting groove 93 are springs of the same material. Specifically, when the temperature of the gas inside the synchronous spinning bobbin 81 changes, the vortex gas can blow the second fan blade 922. The second fan blade 922 can then drive the entire mating frame 92 to rotate inside the mating cavity 91. The size of the vortex can change the rotation speed of the mating frame 92. The synchronous gas passes through the opening. 921 flows into the interior of the coordinating frame 92. The second temperature-sensing spring 97 deforms synchronously due to temperature. When the temperature rises, the second temperature-sensing spring 97 pushes the coordinating block 96 to move upward. The coordinating block 96 then pushes the coordinating rod 94 to swing closer to the side of the spindle frame 82. At this time, the coordinating rod 94 can gently comb the swirling fiber strip, so that it is pulled during swirling, ensuring the quality of forming slub. When the temperature drops, the coordinating rod 94 is pulled back to its original position by the support block 95 to avoid the structure of fine yarn formation. In this way, the coordinating rod 94 can also adapt to the vortex forming slub yarn and change position due to the influence of gas temperature.

[0025] Working principle: Before yarn formation: After the fiber sliver at the front end is guided by the guide tube 74, it is then constrained and conveyed by the side of the traction roller group 73, and the fiber sliver can enter the interior of the spinning cylinder 81 through the feed trough 812.

[0026] During yarn formation: After the fiber sliver enters the spinning drum 81 through the feed trough 812, the air supply module 75 delivers airflow to the spinning drum 81 through the first air pipe to form a vortex. The fiber sliver is guided by the side of the traction rod 811 and is sucked into the air chamber of the spindle frame 82 by the high-speed rotating airflow to be twisted into base yarn. In addition, the fiber flow is subjected to the centrifugal force of the air vortex in the spinning drum 81. After being swung, it is sucked into the air chamber of the spindle frame 82 by the airflow and wrapped around the side of the base yarn to form slub. In this way, the fiber sliver can be vortexed into slub yarn. The slub yarn is discharged through the discharge trough 813. When switching styles of slub yarn, during normal operation, the conveying speed of the traction roller group 73 is controlled by the drive group 72, which causes the fiber strip to accelerate and increase instantly. The excess fiber strip can wrap around the side of the base yarn to form thick sections. Conversely, the fiber strip decelerates and decreases instantly, and the less fiber strip can wrap around the side of the base yarn to form details. During enhanced operation, based on the above, the temperature component inside the gas supply module 75 controls and changes the gas temperature. At this time, the temperature of the gas delivered to the spinning cylinder 81 changes. When the vortex gas is discharged from the exhaust groove 85, the first temperature-sensing spring 853 is affected by the gas. When the temperature rises, the first temperature-sensing spring 853 pushes the movable block 852 to change the cross-section of the exhaust channel, and a larger vortex is generated inside the spinning cylinder 81, which in turn causes more fiber strips to swing and form thicker nodes. When the temperature drops, the first temperature-sensing spring 853 pulls the movable block 852 to change the cross-section of the exhaust channel, and a smaller vortex is generated inside the spinning cylinder 81, which in turn causes fewer fiber strips to swing and form finer nodes. This ensures the formation effect of the bamboo nodes. To assist in the spinning of slub yarn, after the temperature of the gas inside the spinning bobbin 81 changes, the second fan blade 922 is driven by the vortex gas, and the second fan blade 922 drives the mating frame 92 to rotate. The size of the vortex can synchronously change the rotation speed of the mating frame 92, adapting to the frequency of the fiber sliver's swing. Gas enters the interior of the mating frame 92 through the opening 921. The second temperature-sensing spring 97 is affected by the temperature. When the temperature rises, the second temperature-sensing spring 97 pushes the mating block 96 upward, and the mating block 96 can then squeeze the mating rod 94 close to the side of the spindle frame 82. When the spindle is rotated, a larger vortex swings more fiber strips. The faster rotation of the coupling frame 92 allows the coupling rod 94 to gently comb the fiber strips, maintaining the formation of thicker sections. Conversely, when the temperature is lower, the second temperature-sensing spring 97 pulls the coupling block 96 downwards, and the coupling rod 94 can rotate and reset away from the spindle frame 82 under the pull of the support block 95. At this time, the slower rotation of the coupling frame 92 will not contact the side of the swinging fiber strips, so that the fiber strips will not be damaged and the formation of fine sections will be maintained. This adaptive matching ensures the yarn forming effect of slub yarn. To further enhance the thickening effect, by default, the second air pipe of the air supply module 75 does not supply gas, and the spindle frame 82 remains stationary inside the spinning cylinder 81 due to the damping of the constraint frame 832. When the air supply module 75 supplies gas through the second air pipe, the airflow passes through the guide cavity 83 and blows the first fan blade 833, causing the constraint frame 832 to rotate. The spindle frame 82 rotates accordingly, and the fiber strips are flung by the spindle frame 82. At this time, more fiber strips are flung, thus helping to form a more significant thickening effect.

[0027] After spinning: The slub yarn formed in the air chamber of the spindle frame 82 is discharged from the discharge chute 813. The slub yarn is then pulled by the side component of the antistatic component 5 to eliminate static electricity. Subsequently, it is pulled by the winding component 6 for winding operation. After the winding component 6 completes the winding, the material picking component 31 moves to the corresponding position. The finished yarn roll is placed on the conveyor belt position by the internal mechanical arm and other components. Then the winding component 6 resets and continues the winding operation.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
