Description

Technical Field

[0001] This invention relates to the field of yarn processing technology, specifically to a twisting treatment device and method for high-twist yarns. Background Technology

[0002] High-twist yarn refers to a type of yarn with a significantly higher twist rate per unit length than conventional yarn. It typically has higher strength, stiffness, and structural stability, and is widely used in high-end textile products and industrial textiles.

[0003] Because high-twist yarns have significant internal stress and torque between fibers during twisting, resulting in an unstable yarn structure, they typically require steam setting after twisting. This process aims to rearrange fiber molecular chains under hot and humid conditions, releasing internal stress, stabilizing the yarn structure, and improving its subsequent processing and performance. Currently, the industry commonly uses a "wind-up first, then process" method for steam treatment of high-twist yarns. This involves first winding the yarn into a cylindrical or disc-like structure and then placing it in a steamer or steaming cylinder for batch steam treatment. However, due to the dense structure and low porosity between fibers of high-twist yarns, steam cannot quickly penetrate the yarn, especially for larger diameter high-twist yarns. This results in a long steam treatment time. Furthermore, after winding, high-twist yarns are in a multi-layered, dense roll state, making it difficult for steam to quickly and evenly penetrate the inner layers. This can easily lead to inconsistent treatment results, such as large differences in twist setting effects between the inner and outer layers and localized stress residue.

[0004] Therefore, the present invention proposes a twisting treatment device and method for high-twist yarns to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a twisting treatment apparatus and method for high-twist yarns to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A twisting treatment device for high-twist yarn includes a twisting mechanism for twisting several strands of raw yarn to form high-twist yarn, a treatment mechanism for steam setting the formed high-twist yarn, and a winding mechanism for winding the high-twist yarn after the winding treatment. The treatment mechanism includes a base frame and an mounting component mounted on the base frame that can move in the same direction and at the same speed as the high-twist yarn. Two kneading components for kneading the high-twist yarn are arranged opposite each other on the mounting component. Each kneading component includes a hollow steam section. The steam section is evenly distributed with a first steam outlet and hollow punching needles. The punching needles are distributed with a second steam outlet. The treatment mechanism also includes a steam generator for conveying steam to the steam section.

[0007] In one alternative embodiment: the processing mechanism further includes a first driving component for driving the base frame to move in the same direction and at the same speed as the high-twist yarn. The first driving component includes a threaded rod, a guide rod, and a driving member for driving the threaded rod to rotate. The threaded rod passes through the mounting member in a threaded engagement manner, and the guide rod movably passes through the mounting member.

[0008] In one alternative embodiment, the processing mechanism further includes a second drive assembly for driving the two kneading members to knead the high-twist yarn. The second drive assembly includes an adjusting component for adjusting the distance between the two kneading members to match the diameter of the high-twist yarn, and a reciprocating component for causing the two kneading members to move in opposite directions to achieve the kneading action.

[0009] In one alternative: the adjusting component includes two telescopic members mounted on the base frame for driving the two kneading parts to move closer / further apart, respectively.

[0010] In one alternative embodiment: the reciprocating component includes multiple abutting members arranged along the moving path of the mounting component. Each abutting member has two symmetrical inclined sides. The kneading component has a frame, in which a slider is slidably engaged. The movable end of the telescopic component is connected to the corresponding slider. Each of the two kneading components has a push rod, the lower end of which has a roller for abutting against the abutting member. Each abutting member has two symmetrical inclined sides, and the push rods on the two kneading components are offset from each other to correspond to the high and low positions of the abutting members respectively.

[0011] In one alternative: the kneading component further includes a repair section for repairing needle holes in high-twist yarns, the repair section having evenly distributed stroking protrusions.

[0012] In one alternative: the tactile bumps are made of soft silicone material.

[0013] A method for twisting high-twist yarns, using the twisting apparatus for high-twist yarns as described in any of the above technical solutions, includes the following steps: S1: Several strands of raw yarn are twisted together by a twisting mechanism to produce a high-twist yarn; S2: The high-twist yarn produced is steam-set using a processing mechanism. Specifically, the high-twist yarn is conveyed between two kneading components. The mounting component moves in the same direction and at the same speed as the high-twist yarn conveyor, causing the two kneading components to move accordingly. During this stroke, the two kneading components knead the high-twist yarn, causing the punching needles to continuously penetrate into the yarn. Steam is supplied to the steam section through a steam generator. Part of the steam is discharged to the outside through the first steam outlet and sprayed onto the yarn, while part enters the punching needles and is then discharged to the inside of the yarn through the second steam outlet, achieving simultaneous steam penetration of the yarn from both inside and outside. After the mounting component moves in the same direction and at the same speed as the high-twist yarn conveyor to the set stroke, it resets to perform the kneading action on the next high-twist yarn segment, and this cycle continues. S3: The treated high-twist yarn is wound up by a winding mechanism.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: This application employs a single-strand steam setting treatment method for high-twist yarn before winding. The high-twist yarn is transferred between two kneading components, which knead the yarn, causing the punching needles to continuously penetrate the yarn. Steam is supplied to the steam section through a steam generator. Part of the steam is discharged externally through the first steam outlet and sprayed onto the yarn, while part enters the punching needles and is then discharged internally through the second steam outlet. This achieves simultaneous steam penetration of the yarn from both inside and outside. The kneading of the yarn further promotes steam penetration, thereby significantly improving the efficiency and effect of steam treatment for high-twist yarn and ensuring the setting quality of the high-twist yarn.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] See also Figures 1-5 A high-twist yarn twisting treatment device includes a twisting mechanism 2 for twisting several strands of raw yarn to form a high-twist yarn, a treatment mechanism 3 for steam setting the formed high-twist yarn, and a winding mechanism 4 for winding the high-twist yarn after the winding treatment. The treatment mechanism 3 includes a base frame 301 and a mounting member 302 disposed on the base frame 301 and capable of moving in the same direction and at the same speed as the high-twist yarn. Two kneading members 303 are disposed opposite each other on the mounting member 302 for kneading the high-twist yarn. The processing mechanism 3 includes a hollow steam section 3031, on which a first steam outlet 311 and a hollow piercing needle 312 (the piercing needle 312 is connected to the interior of the steam section 3031) are evenly distributed. The piercing needle 312 is provided with a second steam outlet 314. The processing mechanism 3 also includes a steam generator 304 for conveying steam to the steam section 3031. The steam output end of the steam generator 304 is connected to the steam section 3031 on the two kneading parts 303 through a steam guide pipe (hose).

[0026] It should be noted that the punching needle 312 in this application is relatively thin, and the length of the needle segment protruding from the surface of the steam section 3031 is adapted to the actual diameter specification of the high-twist yarn, so that it can penetrate into the interior of the high-twist yarn during the rubbing process without damaging the high-twist yarn; in addition, the twisting mechanism 2 is a ring twisting machine, a double twisting machine, etc., and the winding mechanism 4 includes components such as winding rollers and drive motors, which are existing technologies and will not be described in detail here.

[0027] Several strands of raw yarn are twisted together by the twisting mechanism 2 to form a high-twist yarn. Then, the high-twist yarn is steam-set by the processing mechanism 3. Specifically, the high-twist yarn is conveyed between two kneading members 303. The mounting member 302 moves in the same direction and at the same speed as the high-twist yarn, causing the two kneading members 303 to move accordingly (i.e., during this process, the two kneading members 303 are relatively stationary on the high-twist yarn conveying path). During this stroke, the two kneading members 303 knead the high-twist yarn, causing the punching needles 312 to continuously penetrate the yarn. Steam is supplied to the steam section 3031 by the steam generator 304. Part of the steam is discharged externally through the first steam outlet 311 and sprayed onto the yarn, while part enters the punching needles 312 and is then discharged internally through the second steam outlet 314, achieving simultaneous internal and external steam penetration of the yarn. Combined with the kneading of the yarn... To further promote steam penetration, the mounting component 302 moves in the same direction and at the same speed as the high-twist yarn conveyor to the set stroke and then quickly resets to perform a kneading action on the next high-twist yarn segment (during the reset process, the length of the high-twist yarn conveyor does not exceed the effective processing length of the steam segment 3031, thereby achieving continuous and complete processing of the high-twist yarn without any omissions or unprocessed yarn segments). This cycle repeats until the processed high-twist yarn is finally wound up by the winding mechanism 4. The high-twist yarn is processed in a single strand (not stacked together) before winding, which significantly improves the efficiency and effect of steam treatment of the high-twist yarn and ensures the twisting quality of the high-twist yarn. Additionally, it should be noted that multiple strands of high-twist yarn can be conveyed in parallel between the two kneading components 303 for batch processing. Whether the two kneading components 303 are vertically or horizontally arranged (depending on...) Figure 1 (The angle shown is used for explanation) The settings can be adapted according to how the twisting mechanism 2 outputs high-twist yarn. For example, if the twisting mechanism 2 outputs multiple strands of high-twist yarn in a vertically parallel direction, the two kneading parts 303 are preferably arranged vertically. If the twisting mechanism 2 outputs multiple strands of high-twist yarn in a horizontally parallel direction, the two kneading parts 303 are preferably arranged horizontally. Of course, the transmission path of the output high-twist yarn can also be changed by guiding the guide wheel to adapt to the setting of the two kneading parts 303. This application does not limit this.

[0028] Please see Figure 1 and Figure 2In one embodiment of the present invention, the processing mechanism 3 further includes a first driving component for driving the base frame 301 to move in the same direction and at the same speed as the high-twist yarn transmission. The first driving component includes a threaded rod 308, a guide rod 309 (the threaded rod 308 and the guide rod 309 are aligned with the yarn transmission path), and a driving member 310 for driving the threaded rod 308 to rotate (preferably, the driving member 310 is a servo motor). The threaded rod 308 passes through the mounting member 302 in a threaded engagement manner, and the guide rod 309 movably passes through the mounting member 302. The driving member 310 drives the threaded rod 308 to rotate, thereby driving the mounting member 302 to move in the same direction and at the same speed as the high-twist yarn transmission and to reset, that is, driving the two kneading members 303 to move accordingly.

[0029] Please see Figure 1 , Figure 2 and Figure 6 In one embodiment of the present invention, the processing mechanism 3 further includes a second driving component for driving two kneading members 303 to knead the high-twist yarn. The second driving component includes a distance adjusting component for adjusting the distance between the two kneading members 303 to match the diameter of the high-twist yarn, and a reciprocating component for causing the two kneading members 303 to move in opposite directions to achieve the kneading action. The adjusting component includes two telescopic components 315 mounted on the base frame 301 for driving the two kneading parts 303 to move closer / farther away respectively (the telescopic components 315 are electric telescopic rods, telescopic cylinders, etc. in the prior art). The reciprocating component includes multiple abutment members 307 arranged along the moving path of the mounting member 302. Each abutment member 307 has two symmetrical inclined sides. The kneading member 303 is provided with a frame 316, and a slider 317 is slidably engaged in the frame 316. The movable end of the telescopic member 315 is connected to the corresponding slider 317. Each of the two kneading members 303 is provided with a push rod 305. The lower end of the push rod 305 is provided with a roller 306 for abutting against the abutment member 307. The component 307 includes two symmetrical inclined sides. The push rods 305 on the two kneading components 303 are offset from each other to correspond to the high and low positions of the contact component 307. That is, when the roller 306 on one push rod 305 moves to the high point of the contact component 307 and is about to enter the descending stage, the roller 306 on the other push rod 305 moves to the low point of the contact component 307 and is about to enter the ascending stage. This realizes that the two kneading components 303 move in opposite directions to achieve the kneading action of the high twist yarn.

[0030] In this embodiment, during the same direction and speed movement of the mounting component 302 and the high-twist yarn conveyor, the two telescopic components 315 first extend by a set length, causing the two kneading components 303 to move closer to each other to a set distance (this distance is adapted to the thickness of the high-twist yarn, thus enabling the high-twist yarn to be kneaded). When this distance is reached, the two rollers 306 enter the range where they can abut against the contact components 307. Then, under the lifting action of multiple contact components 307 and the downward action of the kneading components 303 themselves, as the two kneading components 303 move closer to the high-twist yarn conveyor... Moving in the same direction and at the same speed, the two kneading parts 303 move in opposite directions to achieve the kneading action of the high-twist yarn. When the mounting part 302 and the high-twist yarn transmission move in the same direction and at the same speed to the end of the set stroke, the two telescopic parts 315 retract, causing the two kneading parts 303 to move away from each other and reset. That is, the two rollers 306 are removed from the range that can abut against the contacting part 307, so that the two kneading parts 303 do not perform kneading action during the reset stroke, reducing unnecessary loads on the push rod 305, rollers 306 and contacting part 307, thereby helping to improve the working life of the reciprocating parts.

[0031] Please see Figure 3 and Figure 4 In one embodiment of the present invention, the kneading member 303 further includes a repair section 3032 for repairing needle holes on high-twist yarns. The repair section 3032 is uniformly provided with tactile bumps 313, which are made of soft silicone material.

[0032] In this embodiment, during the kneading action of the two kneading parts 303 on the high-twist yarn, the yarn segment after being treated by the steam section 3031 is located in the repair section 3032. The high-twist yarn is touched by the touching protrusions 313 (combined with the high temperature of the yarn after steam treatment, the touching essentially plays the role of heat pressing), thereby repairing the pinholes on the high-twist yarn and ensuring the integrity of the high-twist yarn.

[0033] The present invention also provides a method for twisting high-twist yarns, using the twisting treatment apparatus for high-twist yarns described in any of the above technical solutions, comprising the following steps: S1: Several strands of raw yarn are twisted together by twisting mechanism 2 to form a high-twist yarn; S2: The high-twist yarn produced is steam-set using the processing mechanism 3. Specifically, the high-twist yarn is conveyed between two kneading components 303. The mounting component 302 moves in the same direction and at the same speed as the high-twist yarn conveyor, causing the two kneading components 303 to move accordingly. During this stroke, the two kneading components 303 knead the high-twist yarn, causing the punching needles 312 to continuously penetrate into the yarn. Steam is supplied to the steam section 3031 through the steam generator 304. Part of the steam is discharged to the outside through the first steam outlet 311 and sprayed onto the yarn, while part enters the punching needles 312 and is then discharged into the yarn through the second steam outlet 314, achieving simultaneous steam penetration into the yarn from both inside and outside. After the mounting component 302 moves in the same direction and at the same speed as the high-twist yarn conveyor to the set stroke, it resets to perform the kneading action on the next high-twist yarn section, and this cycle continues. S3: The treated high-twist yarn is wound up by the winding mechanism 4.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
