Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a high-stability lengthened texturing machine unit. Background Art

[0002] In the chemical fiber textile industry, stretch yarn is a key raw material for the production of various apparel fabrics, home textiles, and industrial fabrics. Its production quality and efficiency directly impact a company's market competitiveness. The high-stability, extended-length texturing unit, a core piece of equipment for stretch yarn production, optimizes the structure and upgrades the functionality of traditional texturing machines, effectively improving the stability and consistency of the tow heating, texturing, and shaping processes. This plays a crucial role in meeting market demand for high-quality stretch yarn.

[0003] However, existing high-stability, extended-length texturing units still have numerous deficiencies in the chain transmission. First, the lack of an effective tension adjustment component causes the chain tension to decrease over time due to factors such as wear and temperature fluctuations, leading to problems such as chain slack and tooth skipping. This not only reduces transmission efficiency and increases equipment energy consumption, but can also cause fluctuations in tow tension, resulting in quality defects such as uneven thickness and inconsistent elasticity in the stretch yarn. In severe cases, it can even cause chain breakage, interrupting production and increasing equipment maintenance costs and downtime.

[0004] Secondly, during operation, the existing texturing unit is prone to chain deviation due to factors such as the equipment's own vibration, uneven load distribution, and chain installation errors. Once the chain deflects, its meshing position with the sprocket deviates from the normal trajectory, resulting in uneven contact stress distribution between the chain roller and the sprocket tooth surface. Local areas are subjected to excessive loads, accelerating tooth surface wear, scratches, and even tooth breakage, further aggravating the wear of the chain and sprocket, generating abnormal noise, and at the same time destroying the stability of the yarn transmission, affecting the processing accuracy and product quality of the elastic yarn. In addition, the chain deviation may also cause it to interfere with surrounding components, causing the production line to be shut down for maintenance, affecting the delivery cycle. At the same time, the elastic yarn produced before and after the failure may have batch quality problems due to unstable tension, such as uneven dyeing and reduced breaking strength, increasing the scrap rate. The damaged components pose a safety hazard, further limiting the stable operation of the texturing unit and the improvement of production efficiency.

[0005] Therefore, the present invention proposes a high-stability extended texturizing unit to solve the above problems. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a high-stability, lengthened texturizing unit with the following beneficial effects:

[0020] 1. By setting the first component in the tension adjustment and stabilizing mechanism, under the telescopic control of the electric telescopic rod, the restriction of the pawl on the ratchet is controlled to avoid the reversal of the tension adjustment when the tension adjusting body adjusts the tension of the transmission chain. Under the restriction of the pawl on the ratchet, the one-way locking feature avoids the problem of tension loss control caused by load fluctuation or unexpected external force. The meshing characteristics of the ratchet and the pawl determine that the tension adjustment and stabilizing mechanism can adjust the tension in one direction. For example, when the tension drops, the tension is increased to tighten the transmission chain. With the assistance of the electric telescopic rod, when the tension is too large, the electric telescopic rod can be retracted to release the restriction on the ratchet, causing it to reverse and reduce the tension. The electric telescopic rod extends to restore the one-way locking of the pawl on the ratchet, thereby making the tension adjustment more flexible while adjusting in one direction.

[0021] 2. By setting the second component in the tension adjustment and stabilization mechanism, the tension of the transmission chain is fed back under the coordinated setting of the tension adjustment body and the strain gauge thereon, so as to adjust the tension force in time to ensure that it is always in a reasonable pre-tightened state, avoiding transmission inaccuracy caused by relaxation, and thus making the key components of the synchronous transmission such as the transmission chain in the texturing machine run stably, preventing the rotation speed of each roller from being inconsistent due to loose or over-tight transmission chain, resulting in fluctuation of the yarn draft ratio, sudden change of yarn tension, and defects such as "stiff yarn" and "loose loop yarn", which affect the uniformity of the fineness of the finished yarn. By maintaining the stability of the chain transmission, the constancy of the yarn tension is indirectly guaranteed, and the product qualification rate is improved.

[0022] 3. By setting up the third component in the tension adjustment and stabilization mechanism, it cooperates with the magnetorheological fluid in the magnetorheological fluid chamber while adjusting the tension. The strain gauge on the tension adjustment body monitors the transmission chain tension in real time. The main controller accurately controls the current of the electromagnetic coil in the magnetorheological fluid chamber based on the feedback signal. When the transmission chain tension decreases, the magnetic field is enhanced to increase the viscosity of the magnetorheological fluid, assisting the tensioning component to apply tension stably. When the tension is too large, the magnetic field is reduced to weaken the viscosity, and other structures are cooperated to quickly release the pressure to achieve precise dynamic control of the chain tension. The magnetorheological fluid responds quickly to changes in the magnetic field and can complete viscosity conversion in a very short time, better ensuring the stable operation of the transmission system. The characteristic that the viscosity of the magnetorheological fluid changes with the magnetic field provides additional stable support for the tensioning component. After the tensioning component completes the tension adjustment, the viscosity of the magnetorheological fluid increases to form an effect similar to "damping lock", preventing the tensioning component from shifting due to factors such as vibration and impact, ensuring the continuous stability of the chain tension and reducing transmission failures caused by tension fluctuations.

[0023] 4. Through the setting of the auxiliary transmission guide mechanism, when the transmission chain deviates during transmission, the Hall switch and the contact are triggered close to each other, and then the intake pipe is started to increase the air pressure in the L-shaped rod to reset the guide body, thereby correcting the transmission chain and adjusting its motion trajectory to ensure that the transmission chain is transmitted along the correct path, maintain a constant transmission ratio, avoid power transmission interruption or precision loss caused by deviation, stabilize the transmission chain position, avoid chain jamming, tearing or overload of transmission components caused by excessive deviation, reduce sudden failures and downtime losses, and further avoid the deflection movement from aggravating unilateral wear of itself and surrounding components, resulting in transmission chain stretching, sprocket tooth surface damage or even breakage.

The contact 37 and the Hall switch 34 are in the same parallel line.

[0052] Everything in the above example works as follows:

[0053] The following is a working process of the tension adjustment and stabilization mechanism 2 for assisting in adjusting the power transmission tension during the overall operation of the texturizing body 11 and further assisting in adjusting the stability during the tension adjustment:

[0054] Specifically, the first component runs as follows:

[0055] During use, the texturing machine 11 is started. During the process of processing ordinary chemical fiber raw yarn into elastic yarn, the transmission chain 24 is connected to multiple transmission gears 23 to provide power for the operation of the texturing machine 11. During this process, when the transmission chain 24 is transmitting, the long-term operation process will cause the length to increase due to physical changes such as wear and thermal expansion, thereby reducing the tension. At this time, the pressure of the transmission chain 24 on the surface of the tension regulating body 215 changes. Under the setting of the strain gauge set on the surface of the tension regulating body 215, this pressure change signal is transmitted to the main controller, and then the main controller starts the built-in power supply of the ratchet 28 to drive the ratchet 28. During the reverse rotation of the ratchet 28, the electrically controlled telescopic rod 210 is in an extended state. At this time, the pawl 211 is engaged with the ratchet 28. Due to the setting of the arc-shaped surface of the outer ring of the ratchet 28, the pawl 211 and the ratchet 28 are in contact and slide along the arc surface of the ratchet 28. During the reverse rotation of the ratchet 28, the pawl 211 and the ratchet 28 are in contact and engaged. At this time, the ratchet 28 can only rotate in one direction under the restriction of the pawl 211, so as to prevent the transmission of the transmission chain 24 from compressing the tension regulating body 215 and causing the driven gear plate 213 and the ratchet 28 to reverse under the cooperation of multiple structures, thereby making the tension adjustment unstable.

[0056] By setting the first component in the tension adjustment and stabilizing mechanism 2, under the extension and retraction control of the electrically-controlled telescopic rod 210, the pawl 211 is controlled to restrict the ratchet 28, thereby preventing the tension adjustment from being reversed when the tension adjusting body 215 adjusts the tension of the transmission chain 24. Under the restriction of the pawl 211 on the ratchet 28, the one-way locking feature avoids the problem of tension loss control caused by load fluctuations or unexpected external forces. The meshing characteristics of the ratchet 28 and the pawl 211 determine that the tension adjustment and stabilizing mechanism 2 can adjust the tension in one direction. For example, when the tension decreases, the tension is increased to tighten the transmission chain 24. With the assistance of the electrically-controlled telescopic rod 210, when the tension is too large, the electrically-controlled telescopic rod 210 can be retracted to release the restriction on the ratchet 28, causing it to reverse and reduce the tension. The electrically-controlled telescopic rod 210 then extends to restore the one-way locking of the pawl 211 on the ratchet 28, thereby making the tension adjustment more flexible while achieving one-way adjustment.

[0057] Specifically, the second component runs as follows:

[0058] When in use, the rotation of the ratchet 28 drives the driving gear 212 fixedly connected thereto to rotate synchronously in the opposite direction. Under this movement, since the driving gear 212 is engaged with the driven toothed disc 213 for transmission, the reverse rotation of the driving gear 212 causes the driven toothed disc 213 to rotate forward, and then the forward rotation of the driven toothed disc 213 causes the arc groove 214 opened thereon to deflect synchronously, thereby causing the sliding post 216 slidingly connected in the arc groove 214 to deviate toward the outer ring of the driven toothed disc 213, and then since the tension regulating body 215 is slidably connected in the T-slot 27, the linear limit of the T-slot 27 is Under the push of the control and the arc groove 214, the tension regulating body 215 is prompted to move linearly toward the outer circle of the positioning disk 26, gradually away from the center of the positioning disk 26. At this time, the tension regulating body 215 expands relative to the diameter of the positioning disk 26, thereby correspondingly increasing the resistance force on the transmission chain 24 sliding on the tension regulating body 215. With the cooperation of the strain gauge on the tension regulating body 215, when the pressure of the transmission chain 24 on the tension regulating body 215 is increased to the set value, the surface tension adjustment of the transmission chain 24 is completed. At this time, the ratchet 28 stops rotating, thereby controlling the tension regulating body 215 to stop the outward expansion movement;

[0059] By setting the second component in the tension adjustment and stabilization mechanism 2, under the coordinated setting of the tension adjustment body 215 and the strain gauge thereon, the tension of the transmission chain 24 is fed back, so as to timely adjust the tensioning force to ensure that it is always in a reasonable pre-tightened state, avoiding transmission misalignment caused by relaxation, and thus making the key components of the synchronous transmission such as the transmission chain 24 in the texturizing body 11 run stably, preventing the rotation speeds of the various rollers from being inconsistent due to relaxation or excessive tension of the transmission chain 24, causing fluctuations in the yarn draft ratio, causing sudden changes in the yarn tension, and producing defects such as "stiff yarn" and "loose loop yarn", affecting the uniformity of the fineness of the finished yarn. By maintaining the stability of the chain transmission, the constancy of the yarn tension is indirectly guaranteed, and the product qualification rate is improved.

[0060] Specifically, the operation process of the third component:

[0061] During use, the tension regulating body 215 moves toward the outer ring of the positioning plate 26 to adjust the tension. The slide column 216 moves in the arc groove 214. At the same time, the movement of the tension regulating body 215 drives the guide slider 217 to move linearly in the guide groove 220. The magnetorheological fluid in the magnetorheological fluid chamber 219 is at the initial viscosity. When the strain gauge feedback transmission chain 24 on the tension regulating body 215 reduces the tension of the tension regulating body 215, the strain gauge transmits this signal to the main controller. After the tension adjustment is completed, the main controller increases the current of the electromagnetic coil 221 to enhance the magnetic field strength, so that the magnetorheological fluid in the magnetorheological fluid chamber 219 is at an initial viscosity. The viscosity of the magnetorheological fluid increases, thereby assisting the tension regulating body 215 in stabilizing the tension of the transmission chain 24, avoiding the deviation of the tension regulating body 215, and compensating the tension of the transmission chain 24; on the contrary, when the tension of the transmission chain 24 is too large, the control system reduces the current of the electromagnetic coil 221, reduces the viscosity of the magnetorheological fluid, and cooperates with the electrically controlled telescopic rod 210. The electrically controlled telescopic rod 210 contracts and contacts the restrictive effect on the ratchet 28, and the ratchet 28 rotates forward, prompting the tension regulating body 215 to move into the positioning plate 26, reducing the pressure of the transmission chain 24 on the tension regulating body 215, and thus restoring the tension of the transmission chain 24 to the set range.

[0062] By disposing a third component within the tension adjustment and stabilization mechanism 2, while adjusting the tension, it cooperates with the magnetorheological fluid in the magnetorheological fluid chamber 219. The strain gauge on the tension adjustment body 215 monitors the tension of the transmission chain 24 in real time. The main controller precisely controls the current of the electromagnetic coil 221 within the magnetorheological fluid chamber 219 based on the feedback signal. When the tension of the transmission chain 24 decreases, the magnetic field is enhanced to increase the viscosity of the magnetorheological fluid, assisting the tensioning component in applying stable tension. When the tension is too high, the magnetic field is reduced to weaken the viscosity, and other structures are coordinated to quickly release pressure, achieving precise dynamic control of the chain tension. The magnetorheological fluid responds quickly to changes in the magnetic field and can complete viscosity conversion in a very short time, better ensuring the stable operation of the transmission system. The characteristic that the viscosity of the magnetorheological fluid changes with the magnetic field provides additional stable support for the tensioning component. After the tensioning component completes tension adjustment, the viscosity of the magnetorheological fluid increases, forming an effect similar to "damping lock", preventing the tensioning component from shifting due to factors such as vibration and impact, ensuring continuous and stable chain tension, and reducing transmission failures caused by tension fluctuations.

[0064] The following is the working process of the auxiliary transmission guide mechanism 3 for guiding and assisting the structure in the tension adjustment and stabilization mechanism 2 to prevent deviation:

[0065] When in use, the two guide bodies 35 are respectively arranged on both sides of the transmission chain 24 to provide a guiding function for it. When the elasticizing body 11 is in operation, vibration is generated, thereby causing the transmission chain 24 to deflect. The transmission chain 24 generates a thrust on the guide body 35, thereby causing the guide body 35 to slide toward the inside of the L-shaped rod 32. The contact 37 arranged on the guide body 35 simultaneously approaches the direction of the Hall switch 34 in the L-shaped rod 32 until the contact 37 fits with the Hall switch 34 and triggers the Hall switch 34. When the guide body 35 moves toward the inside of the L-shaped rod 32, the L-shaped through hole 37 is pressed against the Hall switch 34. 6 gradually slides into the L-shaped rod 32, and then the inner wall surface of the L-shaped rod 32 blocks the channel of the side wall of the L-shaped through hole 36. At this time, the contact 37 and the Hall switch 34 are abutted and triggered, prompting the external air pump of the air intake pipe 33 to start. Under the action of the air intake pipe 33, air is supplied to the L-shaped rod 32. The air pressure in the cavity of the L-shaped rod 32 increases, gradually pushing the guide body 35 to move in the direction of the transmission chain 24. Then, under the thrust of the guide body 35 on the transmission chain 24, the transmission chain 24 is assisted to reset, thereby preventing the transmission guide of the transmission chain 24 from deviating, thereby performing a deviation correction operation;

[0066] By setting up the auxiliary transmission guide mechanism 3, when the transmission chain 24 deviates during transmission, the Hall switch 34 is triggered by approaching the contact 37, and then the air intake pipe 33 is started to increase the air pressure in the L-shaped rod 32 to cause the guide body 35 to reset, thereby correcting the transmission chain 24 and adjusting its motion trajectory to ensure that the transmission chain 24 is transmitted along the correct path, maintain a constant transmission ratio, avoid power transmission interruption or precision loss due to deviation, stabilize the position of the transmission chain 24, avoid chain jamming, tearing or overload of transmission components due to excessive deviation, reduce sudden failures and downtime losses, and further avoid the deflection movement from aggravating unilateral wear of itself and surrounding components, resulting in stretching of the transmission chain 24, damage to the sprocket tooth surface or even breakage.
