Description

Technical Field

[0001] This invention relates to the field of false twisters, specifically to a false twister for producing false twisted yarn with flexible guidance. Background Technology

[0002] In the production of simulated silk (crepe), the rotation of the belt drives the main pulley, which in turn drives the active false twist wheel through the drive shaft, then the false twist needle, and finally the driven false twist wheel. Therefore, there is friction loss between the active and driven false twist wheels. The speed difference between the two wheels is 3%, and the loss is even greater when there is oil. The lifespan of the false twist wheel is only about one year.

[0003] Chinese patent CN119615440B discloses an automatic oil-filling false twist device, which can store lubricating oil in the oil tank and realize automatic oiling of bearings without disassembling the false twist unit for oiling, thus facilitating the maintenance of the false twist unit. However, it is insufficient in achieving the effects of cleaning the equipment, automating the components, and modularizing the components. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides the following technical solution: a false twister for producing false twisted yarn with flexible guidance, comprising a false twist base, a connecting shaft inserted into the inner side of the false twist base, the connecting shaft being inserted from the top of the false twist base, a friction disc assembly placed on the connecting shaft, a connecting belt fitted onto a gear block, and then the false twist base fixed to the top of the base platform. A first motor controls the rotation of the gear block, which in turn drives the connecting belt to rotate, which in turn drives the three connecting shafts to rotate simultaneously, thereby achieving the effect of frictional twisting of the yarn. This utilizes the "false twist effect" to achieve the curling deformation of the yarn, and after subsequent tension release or heat setting, it retains a stable curled shape. A friction disc assembly is installed on the outer side of the connecting shaft. This assembly employs an adaptive structure to adapt to tension fluctuations, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven feeding or equipment vibration, the friction disc automatically retracts or adjusts the contact pressure to prevent yarn breakage caused by excessive pressure. When the tension is too low, it automatically increases the contact pressure to ensure stable twisting torque, preventing "slippage" due to insufficient friction, reducing yarn surface fuzz and scratches, and adapting to various yarn types, thus improving equipment versatility. Different yarn densities and materials have significantly different friction pressure requirements. The adaptive friction disc eliminates the need for manual disassembly to adjust the shaft spacing or replace the friction disc, as it can adapt through its own elastic deformation or... The electronic control feedback automatically adapts to the friction requirements of different yarns, significantly shortening changeover and debugging time, improving the equipment's adaptability to multi-variety, small-batch production, compensating for friction disc wear, extending service life, stabilizing twist uniformity, and improving the quality of finished yarn. A gear block is fixedly connected to the bottom of the connecting shaft, and a connecting belt is fitted onto the outer side of the gear block. The equipment is placed in the working position, the yarn is passed through the equipment surface, and the guide component pushes the yarn into the friction disc assembly, facilitating subsequent twisting operations. A guide component is fixedly connected to the outer side of the false twist base. The guide component adopts an automated yarn pushing design to overcome feeding resistance, ensure precise yarn twisting, eliminate feeding tension fluctuations, and stabilize twist. Uniformity, adaptable to automated production, reduced manual intervention costs, automatically pushes the yarn end to the twisting area and completes the initial twisting without manual threading, significantly shortens changeover downtime, and avoids yarn path deviations caused by operational differences during manual threading, improving the automation and consistency of production, adapting to the feeding requirements of special yarn varieties. A wire support is fixedly connected to one side of the false twist base, which is used to guide the yarn operation. A base platform is fixedly connected to the bottom of the false twist base. An outer shell is fixedly connected to one side of the top inside the base platform. A first motor is fixedly connected to the bottom of the outer shell. The output end of the first motor is fixedly connected to the outside of the gear block.

[0005] The guiding component includes a connecting end, on the inner side of which a guide frame is rotatably connected. The guide frame rotates within the connecting end to adjust the angle between the guide frame and the friction disc assembly, facilitating subsequent disassembly and preventing the guide frame from obstructing the friction disc assembly. A first electric push rod is fixedly connected to one side of the guide frame. The extension and retraction of the first electric push rod controls the movement of the component. During the extension and retraction of the first electric push rod, a limiting component extends and retracts. The limiting component restricts the extension and retraction range of the first electric push rod through a sliding structure. A receiving frame is fixedly connected to one side of the first electric push rod. A limiting mechanism is fixedly connected between the receiving frame and the opposing surfaces of the guide frame. The component includes a pushing component fixedly connected to the side of the receiving frame away from the first electric push rod. When the first electric push rod extends, it aligns the pushing component with the junction of the friction disc component. When the first electric push rod retracts, it shifts the pushing component to the junction of the friction disc component. When the pushing component is at the junction, it pushes the line into the inner side of the friction disc component. The friction disc component rotates to rub and twist the line, meeting the needs of subsequent operations. When the equipment needs to be inspected or the line needs to be replaced, the first electric push rod controls the pushing component to shift to the junction of the friction disc component, closer to the guide frame. The pushing component extends and retracts to pull out the line, thereby achieving the function of line exit.

[0006] Preferably, a second motor is fixedly connected to the inner wall of the base platform away from the first motor. The second motor controls the rotation of the friction component, causing the friction component to rub against the friction disk assembly. This removes fiber debris, oil residue, and dust impurities adhering to the disk surface, restores the stability of the surface friction coefficient of the friction disk, ensures consistent twisting quality, prevents impurities from embedding, extends the service life of the friction disk, avoids cross-contamination, adapts to the production needs of multiple yarn varieties, maintains stable airflow in the twisting area, and reduces yarn drift interference. The friction component is fixedly connected to one side of the top of the base platform, and the output end of the second motor is fixedly connected to the bottom of the friction component.

[0007] Preferably, the limiting component includes a limiting housing, with a limiting support rod slidably connected to the inner side of the limiting housing. When the first electric push rod pushes the receiving frame, the limiting support rod drives the limiting block to slide along with the receiving frame. The limiting block slides with the limiting support rod. When the limiting block is against the inner wall of the limiting frame near the receiving frame, the pushing component and the friction disk assembly are aligned, facilitating the internal components of the pushing component to push the line into the inner side of the friction disk assembly. The limiting frame is fixedly connected to the outer side of the limiting housing, and the limiting block is fixedly connected to the outer side of the limiting support rod. When the limiting block is on the side of the limiting frame furthest from the receiving frame, the pushing component is biased towards the friction disk assembly, closer to the guide frame, facilitating the subsequent pushing component to hook out the line. The outer side of the limiting block is slidably connected to the inner side of the limiting frame. By sliding the limiting block on both sides of the inner wall of the limiting frame, the extension and retraction range of the first electric push rod is controlled, thereby meeting different operating requirements, assisting the first electric push rod in extension and retraction, improving the operating accuracy of the component, and avoiding misalignment during extension and retraction that affects operating efficiency.

[0008] Preferably, the pushing assembly includes a pushing frame, with a second electric push rod fixedly connected to one side of the pushing frame. The extension and retraction of the second electric push rod controls the movement of the pushing bracket, which in turn drives the groove of the locking block to align with the yarn. As the second electric push rod extends and retracts, the locking block pushes the yarn, causing it to enter the friction disc assembly. This overcomes feeding resistance, ensures precise yarn twisting, eliminates feeding tension fluctuations, stabilizes twist uniformity, adapts to automated production, reduces manual intervention costs, automatically pushes the yarn end to the twisting area and completes initial twisting without manual threading, significantly shortens changeover downtime, and avoids yarn path deviations caused by operational differences during manual threading, improving the automation and consistency of production. It also adapts to the feeding requirements of special yarn varieties. A pushing bracket is fixedly connected to the side of the second electric push rod away from the pushing frame, and a locking block is fixedly connected to the side of the pushing bracket away from the second electric push rod. A silicone block is placed in the groove of the clamping block. During the movement of the line by the clamping block, the silicone block comes into frictional contact with the line. The silicone block is made of silicone, which has a certain degree of wear resistance and cushioning, thereby reducing the collision between components, reducing surface wear of components, and thus extending the service life of components. It provides flexible clamping, protects sensitive yarns from damage, enhances the friction effect, prevents yarn slippage and deviation, buffers tension fluctuations, maintains feeding stability, and has self-cleaning properties to reduce the accumulation of fiber impurities. The silicone block is fixedly connected to the inner side of the clamping block. A groove is opened on the outer side of the silicone block away from the second electric push rod. When the silicone block pushes the line, the toughness of the line reacts to the surface of the silicone block, and the pressure squeezes the silicone block. The groove enhances the deformation performance of the component and further improves the cushioning effect. The groove breaks the continuous rigid constraint of the material and provides a directional release space for the elastic deformation of the silicone when it is squeezed. An auxiliary component is fixedly connected to the outer side of the clamping block.

[0009] Preferably, the auxiliary component includes an auxiliary frame, with a first spring sleeved on the outer side of the auxiliary frame and an auxiliary block slidably connected to the outer side of the auxiliary frame. During the hooking process, the auxiliary block slides towards one side of the auxiliary frame, compressing and contracting the first spring to provide shock absorption and buffering, reducing the pressure generated by hooking the line, preventing the line from breaking, and preventing any impact on work efficiency. An auxiliary bracket is fixedly connected to one side of the outer side of the auxiliary block. When the pushing component is biased towards the junction of the friction disc component, closer to the guide frame, as the second electric push rod pushes the locking block towards the line, the auxiliary bracket hooks the line, and the second electric push rod contracts, causing the auxiliary bracket to move the line, thereby completing the function of hooking the line.

[0010] Preferably, the friction disc assembly includes a friction tool. As the friction tool rotates with the connecting shaft, the wheel rim, made of a flexible material, deforms during rotation. Therefore, the wheel rim collides with and contacts the constraint block during rotation. The constraint block restricts the deformation range of the wheel rim, keeping it within a controllable range. This allows for smooth friction operation when the wheel rim approaches the line. Ring frames are rotatably connected to both sides of the friction tool. A folding frame is fixedly connected to the outer side of the ring frame. The folding frame employs a folding structure design to enhance the stability of the support, improve its ductility, reduce metal fatigue, and maintain stability. The components operate smoothly. A constraint block is fixedly connected to the side of the folding frame away from the ring frame. A wheel ring is provided on the outer side of the friction tool. The wheel ring is made of flexible material, which reduces the probability of line breakage and improves the quality of operation when rubbing against the line. The wheel ring is connected to the friction tool, which adopts an adaptive structure. When the wheel ring is squeezed by the line of varying thickness, the friction tool can easily drive the wheel ring to appropriately contract and support it, thereby achieving an adaptive squeezing effect, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven yarn feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard squeezing.

[0011] Preferably, the friction device includes a friction housing, with a second spring fixedly connected to the inner side of the friction housing. The friction housing contracts and supports itself according to the second spring, achieving an adaptive compression effect, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression. A friction support rod is fixedly connected to one side of the second spring, and a friction frame is fixedly connected to the side of the friction support rod away from the second spring. When a wheel set ring is fitted inside the friction frame, and the surface of the wheel set ring is subjected to pressure, the friction frame drives the friction support rod to compress and contract the second spring, thereby providing shock absorption and buffering. Guide plates are fixedly connected to the upper and lower sides of the friction frame. As the friction frame contracts towards the friction housing, the friction frame drives the guide plates to contract towards the friction housing, causing the inner side of the guide plate to slide against the outer side of the friction housing. The guide plates guide the sliding direction of the friction frame, preventing deviation during sliding and improving stability during the sliding process.

[0012] Preferably, the wheel assembly includes a plastic shell made of plastic material with a certain degree of extensibility, allowing it to shift appropriately with the friction frame. An elastic ball is disposed on the inner side of the plastic shell. When the plastic film contacts the yarn, it compresses and deforms the elastic ball. During this deformation, the elastic balls rub against each other and stack, thus providing a fixed support. The elastic ball supports the plastic shell, enabling adaptive contact pressure adjustment, ensuring uniform twist, providing flexible protection, reducing yarn fuzz and breakage, buffering vibration and impact, extending the service life of the friction disc, assisting in guidance, preventing yarn deviation, reducing noise and vibration, and optimizing the working environment. A plastic film is fixedly connected to one side of the outer side of the plastic shell.

[0013] Preferably, the friction component includes a fixed end, and a rotating shaft is rotatably connected to the inner side of the fixed end. The rotating shaft is controlled to rotate by a second motor, causing the rotating shaft to drive the grinding wheel assembly to rub against the equipment. The grinding wheel assembly rubs against the surface of the wheel ring, thereby removing fiber debris, oil residue, and dust impurities attached to the disc surface, restoring the surface friction coefficient stability of the friction disc, ensuring consistent twisting quality, preventing impurities from embedding, extending the service life of the friction disc, avoiding cross-contamination, adapting to the production needs of multiple yarn varieties, maintaining stable airflow in the twisting zone, and reducing yarn drift interference. A receiving plate is fixedly connected to the top of the rotating shaft, and a hydraulic column is fixedly connected to the top of the receiving plate. The hydraulic column controls the positioning plate to press against the grinding wheel assembly. The positioning plate applies pressure from the top of the grinding wheel assembly, and the receiving plate supports it from the bottom, thereby fixing the component and preventing shaking during operation, which would affect the friction effect. A positioning plate is fixedly connected to the top of the hydraulic column, and the grinding wheel assembly is set on the outer side of the hydraulic column. The grinding wheel assembly adopts a modular splicing structure and is set on the receiving plate, which facilitates the disassembly and assembly of the grinding wheel assembly.

[0014] Preferably, the abrasive assembly includes a first tool and a second tool that are connected to the outside of the hydraulic column, allowing the first tool and the second tool to be spliced ​​and assembled. This achieves the function of modular assembly, facilitating subsequent disassembly and installation, and reducing the difficulty of subsequent operation of the component. The second tool is inserted and connected to one side of the outside of the first tool. A brush block is fixedly connected to the outside of the first tool and the second tool. The brush block is set on the surface of the component. As the rotating shaft drives the first tool and the second tool to rotate, the brush block rubs against the surface of the wheel assembly ring, thereby facilitating friction cleaning of the component, reducing impurities on the surface of the component, and avoiding affecting the working quality of the component.

[0015] This invention provides a false twisting device with flexible guidance for producing false twisted yarn. It has the following beneficial effects:

[0016] I. This false twister for producing false twisted yarn with flexible guidance uses a second electric push rod to extend and retract, moving the support frame and aligning the groove of the clamping block with the yarn. As the second electric push rod extends and retracts, the clamping block pushes the yarn into the friction disc assembly, thus overcoming feeding resistance, ensuring precise yarn twisting, eliminating feeding tension fluctuations, stabilizing twist uniformity, adapting to automated production, reducing manual intervention costs, automatically pushing the yarn end to the twisting area and completing initial twisting without manual threading, significantly shortening changeover downtime, and avoiding yarn path deviations caused by operational differences during manual threading, improving the automation and consistency of production, adapting to the feeding requirements of special yarn varieties, and incorporating silicone at the clamping block groove. During the movement of the line, the silicone block and the line come into frictional contact. The silicone block is made of silicone, which has a certain degree of wear resistance and cushioning, thereby reducing collisions between components, reducing surface wear, and extending the service life of the components. The flexible clamping protects sensitive yarns from damage, enhances the friction effect, prevents yarn slippage and deviation, buffers tension fluctuations, maintains feeding stability, and has self-cleaning properties to reduce the accumulation of fiber impurities. When the silicone block pushes the line, the toughness of the line reacts to the surface of the silicone block, and the pressure squeezes the silicone block. The grooves on the block surface enhance the deformation performance of the component and further improve the cushioning effect. The grooves break the continuous rigid constraint of the material, providing a directional release space for the elastic deformation of the silicone when it is squeezed.

[0017] II. This false twister for producing false twisted yarn with flexible guidance features a friction tool that rotates with the connecting shaft. The wheel ring, made of flexible material, deforms during rotation, causing it to collide with the constraint block. The constraint block limits the deformation range of the wheel ring, keeping it within a controllable range. This ensures smooth friction operation when the wheel ring is close to the yarn. The folding frame employs a folding structure design to enhance the stability and ductility of the support, reducing metal fatigue and ensuring stable operation. The flexible material of the wheel ring reduces the probability of yarn breakage and improves work quality during friction. Furthermore, the friction tool, connected to the wheel ring, features an adaptive structure. When the wheel ring is subjected to pressure from yarn of varying thicknesses, the friction tool facilitates appropriate contraction and support, achieving adaptive compression and reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven feeding or equipment vibration, the friction disc automatically retracts or adjusts the contact pressure to prevent yarn breakage caused by hard compression.

[0018] III. This false twister for producing false twisted yarn with flexible guidance, when the inner side of the friction frame is fitted with a wheel ring, and the surface of the wheel ring is subjected to pressure, causes the friction frame to drive the friction support rod to compress and contract the second spring, thereby playing a role in shock absorption and buffering. According to the contraction and support of the second spring, it achieves an adaptive compression effect, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven yarn feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression. During the process of the friction frame contracting towards the friction shell, the friction frame drives the guide plate to contract towards the friction shell, so that the inner side of the guide plate slides into contact with the outer side of the friction shell. The guide plate plays a role in guiding the sliding direction of the friction frame, avoiding deviation during the sliding process, and improving the stability during the sliding process.

[0019] IV. This false twister for producing false twisted yarn with flexible guidance compresses and deforms the elastic spheres when the plastic film comes into contact with the yarn. During the deformation of the plastic film, the elastic spheres rub against each other and stack up, thereby generating a fixed support effect. The elastic spheres support the plastic shell, which can adaptively adjust the contact pressure, ensure uniform twist, provide flexible protection, reduce yarn hair and breakage, buffer vibration and impact, extend the service life of the friction disc, assist in guidance, prevent yarn deviation, reduce noise and vibration, and optimize the working environment. The plastic shell is made of plastic material, which has a certain degree of extensibility, allowing the plastic shell to be appropriately offset with the friction frame.

[0020] V. This false twister for producing false twisted yarn with flexible guidance uses a second motor to control the rotation of the rotating shaft. The rotating shaft drives the grinding wheel assembly to rub against the equipment. The grinding wheel assembly rubs against the surface of the wheel ring, thereby removing fiber debris, oil residue, and dust impurities attached to the disc surface, restoring the surface friction coefficient stability of the friction disc, ensuring consistent twisting quality, preventing impurities from embedding, extending the service life of the friction disc, avoiding cross-contamination, adapting to the needs of changing production of multiple yarn varieties, maintaining stable airflow in the twisting zone, and reducing yarn drift interference. The grinding wheel assembly adopts a modular splicing structure and is set on the support plate, which facilitates the disassembly and assembly of the grinding wheel assembly. The positioning plate is controlled by a hydraulic column to press the grinding wheel assembly. The positioning plate applies pressure from the top of the grinding wheel assembly, and the support plate supports the grinding wheel assembly from the bottom, thereby fixing the components and preventing shaking during operation, which would affect the friction effect.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] First embodiment, such as Figures 1 to 5As shown, the present invention provides a technical solution: a false twister for producing false twisted yarn with flexible guidance, comprising a false twist base 2, a connecting shaft 3 inserted into the inner side of the false twist base 2, a friction disc assembly 8 disposed on the outer side of the connecting shaft 3, a gear block 4 fixedly connected to the bottom of the connecting shaft 3, a connecting belt 5 sleeved on the outer side of the gear block 4, a guide component 7 fixedly connected to the outer side of the false twist base 2, a wire bracket 12 fixedly connected to one side of the outer side of the false twist base 2, a base platform 1 fixedly connected to the bottom of the false twist base 2, an outer housing 6 fixedly connected to one side of the top inside the base platform 1, a first motor 10 fixedly connected to the bottom of the outer housing 6, and the output end of the first motor 10 connected to the gear block 4. External fixed connection; place the equipment in the working position, pass the yarn through the surface of the equipment, and push the yarn into the friction disc assembly 8 through the guide component 7 to facilitate subsequent twisting operations. The connecting shaft 3 is inserted from the top of the false twist base 2, the friction disc assembly 8 is placed on the connecting shaft 3, the connecting belt 5 is sleeved on the gear block 4, and then the false twist base 2 is fixed on the top of the base platform 1. The first motor 10 controls the gear block 4 to rotate, the rotation of the gear block 4 drives the connecting belt 5 to rotate, and the rotation of the connecting belt 5 drives the three connecting shafts 3 to rotate simultaneously, thereby achieving the effect of frictional twisting of the yarn. The "false twist effect" is used to achieve the curling deformation of the yarn, and after the subsequent tension is released or heat setting, a stable curled shape is maintained. The friction disc assembly 8 adopts an adaptive structure to adapt to tension fluctuations, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression. When the tension is too low, it can automatically increase the contact pressure to ensure stable twisting torque and prevent "slippage" due to insufficient friction. This reduces yarn surface fuzz and scratches, adapting to various yarn types and improving equipment versatility. Different yarn densities and materials have significantly different friction pressure requirements. The adaptive friction disc eliminates the need for manual disassembly to adjust the shaft spacing or replace the friction disc; it automatically adapts to different yarns through its own elastic deformation or electronic feedback. Friction requirements are significantly reduced, production changeover and debugging time is shortened, the equipment's adaptability to multi-variety, small-batch production is improved, friction disc wear is compensated for, service life is extended, twist uniformity is stabilized, and finished yarn quality is improved. The guide component 7 adopts an automated yarn pushing design, which overcomes feeding resistance, ensures precise yarn twisting, eliminates feeding tension fluctuations, stabilizes twist uniformity, adapts to automated production, reduces manual intervention costs, automatically pushes the yarn end to the twisting area and completes initial twisting without manual threading, significantly shortens production changeover downtime, and avoids yarn path deviations caused by operational differences during manual threading, improving the automation and consistency of production, and adapting to the feeding requirements of special yarn varieties.

[0033] The guide component 7 includes a connecting end 71, a guide frame 72 is rotatably connected to the inner side of the connecting end 71, a first electric push rod 74 is fixedly connected to one side of the guide frame 72, a receiving frame 75 is fixedly connected to one side of the first electric push rod 74, a limiting component 73 is fixedly connected between the opposite surfaces of the receiving frame 75 and the guide frame 72, and a pushing component 76 is fixedly connected to the outer side of the receiving frame 75 away from the first electric push rod 74. The guide frame 72 rotates inside the connecting end 71 to adjust the angle between the guide frame 72 and the friction disk assembly 8, facilitating subsequent disassembly and preventing the guide frame 72 from obstructing the friction disk assembly 8. The first electric push rod 74 extends and retracts to control the movement of the pushing component 76. During the extension and retraction of the first electric push rod 74, it drives the limiting component 73 to extend and retract. The limiting component 73 limits the extension and retraction range of the first electric push rod 74 through a sliding structure. When the first electric push rod 74 extends, it aligns the pushing component 76 with the junction of the friction disk assembly 8. When the first electric push rod 74 retracts, it causes the pushing component 76 to be biased towards the junction of the friction disk assembly 8. When the pushing component 76 is at the junction, it pushes the line into the inner side of the friction disk assembly 8. The friction disk assembly 8 rotates to rub and twist the line, meeting the needs of subsequent operations. When the equipment needs to be inspected or the line needs to be replaced, the first electric push rod 74 controls the pushing component 76 to be biased towards the junction of the friction disk assembly 8, closer to the guide frame 72. The pushing component 76 extends and retracts to pull out the line, thereby achieving the function of line exit.

[0034] A second motor 11 is fixedly connected to the inner wall of the base platform 1 on the side away from the first motor 10. A friction component 9 is fixedly connected to the top side of the base platform 1. The output end of the second motor 11 is fixedly connected to the bottom of the friction component 9. The friction component 9 is rotated by the second motor 11, causing the friction component 9 to rub against the surface of the friction disc assembly 8. This removes fiber debris, oil residue, and dust impurities attached to the disc surface, restores the stability of the surface friction coefficient of the friction disc, ensures consistent twisting quality, prevents impurities from embedding, extends the service life of the friction disc, avoids cross-contamination, adapts to the production needs of multiple yarn varieties, maintains stable airflow in the twisting area, and reduces yarn drift interference.

[0035] The limiting component 73 includes a limiting housing 731, a limiting support rod 732 slidably connected to the inner side of the limiting housing 731, a limiting frame 734 fixedly connected to the outer side of the limiting housing 731, a limiting block 733 fixedly connected to the outer side of the limiting support rod 732, and the outer side of the limiting block 733 slidably connected to the inner side of the limiting frame 734. When the first electric push rod 74 pushes the receiving frame 75, the limiting support rod 732 drives the limiting block 733 to slide along with the receiving frame 75. The limiting block 733 slides with the limiting support rod 732. When the limiting block 733 is close to the inner wall of the limiting frame 734 near the receiving frame 75, the pushing component 76 is aligned with the friction disk assembly 8, which facilitates the internal components of the pushing component 76 to push the line into the inner side of the friction disk assembly 8. When the limiting block 733 is on the side of the limiting frame 734 furthest from the receiving frame 75, the pushing component 76 is biased at the junction of the friction disk assembly 8, closer to the guide frame 72, which facilitates the subsequent pushing component 76 to hook out the line. By sliding the limiting block 733 on both sides of the inner wall of the limiting frame 734, the extension and retraction range of the first electric push rod 74 is controlled, thereby meeting different operating requirements, assisting the first electric push rod 74 in extension and retraction, improving the operating accuracy of the components, and avoiding the impact of extension and retraction misalignment on operating efficiency.

[0036] The pushing assembly 76 includes a pushing frame 761. A second electric push rod 762 is fixedly connected to one side of the outer side of the pushing frame 761. A pushing bracket 763 is fixedly connected to the outer side of the second electric push rod 762 away from the pushing frame 761. A locking block 764 is fixedly connected to the outer side of the pushing bracket 763 away from the second electric push rod 762. A silicone block 765 is fixedly connected to the inner side of the locking block 764. A groove 766 is formed on the outer side of the silicone block 765 away from the second electric push rod 762. An auxiliary assembly 767 is fixedly connected to the outer side of the locking block 764. The second electric push rod 762 extends and retracts to control the movement of the bracket 763, which in turn moves the groove of the locking block 764 to align with the yarn. As the second electric push rod 762 extends and retracts, the locking block 764 pushes the yarn into the friction disc assembly 8. This overcomes feeding resistance, ensures precise yarn twisting, eliminates feeding tension fluctuations, stabilizes twist uniformity, adapts to automated production, reduces manual intervention costs, automatically pushes the yarn end to the twisting area and completes initial twisting without manual threading, significantly shortens changeover downtime, and avoids yarn path deviations caused by operational differences during manual threading, improving the automation and consistency of production. It also adapts to the feeding requirements of special yarn varieties. A silicone block 765 is installed in the groove of the locking block 764. During the movement of the line, the silicone block 765 comes into frictional contact with the line. The silicone block 765 is made of silicone, which has a certain degree of wear resistance and cushioning, thereby reducing the collision between components, reducing surface wear, and extending the service life of the components. It provides flexible clamping to protect sensitive yarns from damage, enhances the friction effect, prevents yarn slippage and deviation, buffers tension fluctuations, maintains feeding stability, and has self-cleaning properties to reduce the accumulation of fiber impurities. When the silicone block 765 pushes the line, the toughness of the line reacts to the surface of the silicone block 765, and the pressure squeezes the silicone block 765. By opening grooves 766 on the block surface, the deformation performance of the component is enhanced, further improving the cushioning effect. The grooves break the continuous rigid constraint of the material, providing a directional release space for the elastic deformation of the silicone when it is squeezed.

[0037] The auxiliary component 767 includes an auxiliary frame 7671, with a first spring 7673 sleeved on the outer side of the auxiliary frame 7671. An auxiliary block 7672 is slidably connected to the outer side of the auxiliary frame 7671, and an auxiliary bracket 7674 is fixedly connected to one side of the auxiliary block 7672. When the pushing component 76 is positioned at the junction of the friction disc component 8, closer to the guide frame 72, as the second electric push rod 762 pushes the locking block 764 towards the line, the auxiliary bracket 7674 hooks the line. The second electric push rod 762 retracts, causing the auxiliary bracket 7674 to move the line, thus completing the hooking of the line. During the hooking process, the auxiliary block 7672 slides towards the auxiliary frame 7671, compressing and contracting the first spring 7673, thereby providing shock absorption and buffering, reducing the pressure generated by hooking the line, preventing the line from breaking, and preventing any impact on work efficiency.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7 As shown, the friction disc assembly 8 includes a friction tool 81. Ring frames 82 are rotatably connected to both sides of the friction tool 81. A folding frame 83 is fixedly connected to the outer side of the ring frame 82. A constraint block 84 is fixedly connected to the outer side of the folding frame 83 away from the ring frame 82. A wheel ring 85 is provided on the outer side of the friction tool 81. When the friction tool 81 rotates with the connecting shaft 3, the wheel ring 85, made of flexible material, deforms during rotation. Therefore, the wheel ring 85 collides with the constraint block 84 during rotation. The constraint block 84 constrains the deformation range of the wheel ring 85, keeping it within a controllable range. This allows for smooth friction operation when the wheel ring 85 is close to the line. Simultaneously, the folding frame 83 adopts a folding structure design to enhance the stability of the support, improve its ductility, reduce metal fatigue, and maintain stable operation of the components. The wheel rim 85 is made of flexible material, which reduces the probability of yarn breakage and improves work quality when it rubs against the yarn. Secondly, the wheel rim 85 is connected to the friction tool 81, which adopts an adaptive structure. When the wheel rim 85 is squeezed by the yarn of different thicknesses, the friction tool 81 can easily drive the wheel rim 85 to appropriately contract and support, thereby achieving the effect of adaptive compression, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven yarn feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression.

[0039] The friction device 81 includes a friction housing 811, a second spring 812 is fixedly connected to the inner side of the friction housing 811, a friction support rod 813 is fixedly connected to one side of the second spring 812, a friction frame 814 is fixedly connected to the outer side of the friction support rod 813 away from the second spring 812, and guide plates 815 are fixedly connected to the upper and lower sides of the outer side of the friction frame 814. When the inner side of the friction frame 814 is fitted with the wheel ring 85, and the surface of the wheel ring 85 is subjected to pressure, the friction frame 814 drives the friction support rod 813 to compress and contract the second spring 812, thereby playing a role in shock absorption and buffering. According to the contraction and support of the second spring 812, the self-adaptive compression effect is achieved, reducing yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven yarn feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression. During the process of the friction frame 814 contracting towards the friction housing 811, the friction frame 814 drives the guide plate 815 to contract towards the friction housing 811, so that the inner side of the guide plate 815 slides into contact with the outer side of the friction housing 811. The guide plate 815 plays a role in guiding the sliding direction of the friction frame 814, preventing deviation during sliding and improving stability during sliding.

[0040] The wheel assembly 85 includes a plastic housing 851, with an elastic ball 852 disposed on the inner side of the plastic housing 851, and a plastic film 853 fixedly connected to one side of the outer side of the plastic housing 851. When the plastic film 853 comes into contact with the yarn, it compresses and deforms the elastic ball 852. During the deformation of the plastic film 853, the elastic balls 852 rub against each other and stack, thereby generating a fixed support effect. This allows the elastic balls 852 to support the plastic housing 851, providing adaptive contact pressure adjustment, ensuring uniform twist, providing flexible protection, reducing yarn fuzz and breakage, buffering vibration and impact, extending the service life of the friction disc, assisting in guidance, preventing yarn deviation, reducing noise and vibration, and optimizing the working environment. The plastic housing 851 is made of plastic material, which has a certain degree of extensibility, allowing the plastic housing 851 to be appropriately offset with the friction frame 814.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9As shown, the friction component 9 includes a fixed end 91, a rotating shaft 92 rotatably connected to the inner side of the fixed end 91, a receiving plate 93 fixedly connected to the top of the rotating shaft 92, a hydraulic column 94 fixedly connected to the top of the receiving plate 93, a positioning plate 95 fixedly connected to the top of the hydraulic column 94, and a grinding tool assembly 96 provided on the outer side of the hydraulic column 94. The second motor 11 controls the rotation of the rotating shaft 92, which in turn drives the grinding wheel assembly 96 to rub against the equipment. The grinding wheel assembly 96 rubs against the surface of the wheel ring 85, thereby removing fiber debris, oil residue, and dust impurities attached to the disc surface, restoring the surface friction coefficient stability of the friction disc, ensuring consistent twisting quality, preventing impurities from embedding, extending the service life of the friction disc, avoiding cross-contamination, adapting to the production needs of multiple yarn varieties, maintaining stable airflow in the twisting zone, and reducing yarn drift interference. The grinding wheel assembly 96 adopts a modular splicing structure and is set on the support plate 93, which facilitates the disassembly and assembly of the grinding wheel assembly 96. The positioning plate 95 is pressed against the grinding wheel assembly 96 by the hydraulic column 94. The positioning plate 95 applies pressure from the top of the grinding wheel assembly 96, and the support plate 93 supports the grinding wheel assembly 96 from the bottom, thereby fixing the components and preventing shaking during operation, which would affect the friction effect.

[0042] The abrasive assembly 96 includes a first tool 961, with a second tool 962 inserted into one side of the first tool 961. A brush block 963 is fixedly connected to the outer sides of the first tool 961 and the second tool 962. The first tool 961 and the second tool 962 are aligned with the outer side of the hydraulic column 94, allowing them to be assembled in a modular fashion. This facilitates subsequent disassembly and installation, reducing the difficulty of subsequent operations. The brush block 963 is located on the surface of the component. As the rotating shaft 92 drives the first tool 961 and the second tool 962, the brush block 963 rotates, causing it to rub against the surface of the wheel assembly ring 85. This facilitates friction cleaning of the component, reduces surface impurities, and prevents any impact on the quality of the component's operation.

[0043] In use, place the equipment in the working position, pass the yarn through the surface of the equipment, and push the yarn into the friction disc assembly 8 through the guide component 7 to facilitate subsequent twisting operations. The connecting shaft 3 is inserted from the top of the false twist base 2, and the friction disc assembly 8 is placed on the connecting shaft 3. The connecting belt 5 is fitted onto the gear block 4, and then the false twist base 2 is fixed to the top of the base platform 1. The first motor 10 controls the rotation of the gear block 4, which drives the connecting belt 5 to rotate. The rotation of the connecting belt 5 drives the three connecting shafts 3 to rotate simultaneously, thereby achieving the effect of frictional twisting of the yarn. The "false twist effect" is used to achieve the curling deformation of the yarn, and after the subsequent tension is released or heat setting, a stable curled shape is maintained. The friction disc assembly 8 adopts an adaptive structure to adapt to tension fluctuations, reduce yarn breakage and fuzz. When the yarn experiences tension peaks due to uneven yarn feeding or equipment vibration, the friction disc can automatically retract or adjust the contact pressure to avoid yarn breakage caused by hard compression. When the tension is too low, it can automatically increase the contact pressure to ensure stable twisting torque and prevent damage due to friction. Insufficient friction can lead to "slippage and twisting," reducing yarn surface fuzz and scratches. It adapts to various yarn types, improving equipment versatility. Different yarn densities and materials have significantly different friction pressure requirements. The adaptive friction disc eliminates the need for manual disassembly to adjust shaft spacing or replace the disc. Through its own elastic deformation or electronic feedback, it automatically adapts to the friction requirements of different yarns, significantly shortening changeover and debugging time. This enhances the equipment's adaptability to multi-variety, small-batch production, compensates for friction disc wear, extends its service life, stabilizes twist uniformity, and improves finished yarn quality. The guide component 7 employs an automated yarn-pushing design to overcome feeding resistance, ensure precise yarn twisting, eliminate feeding tension fluctuations, stabilize twist uniformity, adapt to automated production, and reduce manual intervention costs. It automatically pushes the yarn end to the twisting area and completes initial twisting without manual threading, significantly shortening changeover downtime. It also avoids yarn path deviations caused by operational differences during manual threading, improving production automation and consistency, and adapting to the feeding requirements of special yarn varieties.
