Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn production technology, and in particular to a yarn tension controller with self-cleaning function. Background Technology
[0002] A yarn tension controller is a specialized device used in textile machinery to regulate the tension of yarn during processing. It consists of a tension adjustment module, a transmission wheel, and a control unit. The device acquires real-time tension data of the yarn during operation through a detection module. After analysis and processing by the control unit, the adjustment module drives the transmission wheel to adjust the speed and pressure, ensuring that the yarn maintains a stable tension value. Applied to yarn processing production lines, it is a core component for ensuring yarn processing accuracy and product quality.
[0003] A yarn tension controller maintains constant yarn tension during operation, preventing yarn breakage and stretching deformation due to excessive tension, and yarn slack and disordered arrangement due to insufficient tension. It ensures uniform stretching during the conversion of roving to fine yarn, guarantees tension matching during warp and weft interlacing, and reduces defects such as uneven density, warp breaks, and weft breaks in fabrics. It also improves the quality of package forming and the adaptability to subsequent processing, making it a key piece of equipment for connecting various textile processes and ensuring continuous and stable production.
[0004] Currently available yarn tension controllers lack self-cleaning capabilities during long-term operation. During yarn processing, friction and stretching generate small amounts of fiber debris. These debris, along with minute impurities in the yarn processing environment, gradually adhere to the surface of the tension controller's transmission wheel and the gaps between the wheels. As operating time increases, the accumulated residual yarn and impurities continuously increase, leading to increased rotational resistance of the transmission sprocket and even wheel jamming. Wheel jamming not only forces the production line to stop for maintenance, affecting production efficiency, but may also cause significant yarn breakage due to sudden uneven stress on the yarn, increasing production losses. Furthermore, frequent shutdowns for maintenance shorten the lifespan of the tension controller and increase equipment maintenance costs. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a yarn tension controller with a self-cleaning function, comprising a rotary motor 1, a positive and negative charge generator 2 disposed on the left side of the rotary motor 1, a self-cleaning mechanism 3 disposed on the rear side of the rotary motor 1, the self-cleaning mechanism 3 being used to clean dust generated on the yarn tension control wheel, and an electrostatic elimination mechanism 4 disposed on the rear side of the positive and negative charge generator 2, the electrostatic elimination mechanism 4 being used to eliminate static electricity generated during the yarn stroke.
[0034] The self-cleaning mechanism 3 includes a dust-collecting fan 31. The front side of the dust-collecting fan 31 is fixedly connected to the output end of the positive and negative charge generator 2. An outer connecting ring 32 is fixedly connected to the outer side of the dust-collecting fan 31. A front protective frame 33 is fixedly connected to the rear side of the dust-collecting fan 31. A front dust-collecting pipe 34 is fixedly connected to the rear side of the front protective frame 33. A lower connecting piece 35 is fixedly connected to the bottom of the outer connecting ring 32. A lower connecting plate 36 is fixedly connected to the bottom of the lower connecting piece 35. A dust collection assembly 37 is provided on the top rear side of the lower connecting plate 36. A pulley scraping assembly 38 is provided on the top of the lower connecting plate 36.
[0035] Specifically, when the device is started, the self-cleaning mechanism 3 enters the working state, and the dust suction fan 31 starts to run. Since the front side of the dust suction fan 31 is fixedly connected to the output end of the positive and negative charge generator 2, the power generated by the positive and negative charge generator 2 during operation can be directly transmitted to the dust suction fan 31, providing energy for the continuous operation of the dust suction fan 31, ensuring that the dust suction fan 31 can stably maintain the set rotation speed, thereby generating a stable airflow suction force.
[0036] The airflow suction directly acts on the engagement point of the yarn tension control wheel. When the yarn runs on the tension control wheel, residual impurities are easily accumulated at the engagement point. The suction force generated by the dust suction fan 31 can peel off these accumulated impurities from the engagement point and move them in the direction of the dust suction fan 31, providing conditions for subsequent impurity collection. An outer connecting ring 32 is fixedly connected to the outside of the dust suction fan 31. The outer connecting ring 32 surrounds the outside of the dust suction fan 31, forming a wrap-around support for the outer structure of the dust suction fan 31. During high-speed operation, the dust suction fan 31 is protected from the influence of airflow reaction force and its own rotational inertia, which may cause slight structural shaking. The outer connecting ring 32 can counteract these forces through its rigid structure, maintaining the positional stability of the dust suction fan 31 and preventing the suction direction from changing due to the offset of the dust suction fan 31, ensuring that the suction force always acts accurately on the engagement point of the tension control wheel.
[0037] A front protective frame 33 is fixedly connected to the rear side of the dust suction fan 31. The front protective frame 33 adopts a hollow structure, which can not only not obstruct the airflow, but also prevent foreign objects in the external environment from entering the dust suction fan 31. This prevents foreign objects from colliding with the blades of the dust suction fan 31, causing damage to the blades or obstruction of rotation. It can guide the airflow behind the dust suction fan 31, so that the impurities adsorbed by the suction can move along the direction guided by the front protective frame 33 under the drive of the airflow, avoiding the accumulation of impurities behind the dust suction fan 31. A front dust suction pipe 34 is fixedly connected to the rear side of the front protective frame 33. The inlet end of the front dust suction pipe 34 corresponds to the hollow area of the front protective frame 33. The impurities adsorbed by the dust suction fan 31 and guided by the front protective frame 33 will directly enter the interior of the front dust suction pipe 34. The front dust suction pipe 34, through its own tubular structure, transports the impurities from the vicinity of the dust suction fan 31 to an area away from the tension control wheel, preventing the impurities from scattering around the dust suction fan 31 and re-attaching to the surface of the tension control wheel or other parts, causing secondary pollution.
[0038] The bottom of the outer connecting ring 32 is fixedly connected to a lower connecting piece 35, which extends vertically downwards and is fixedly connected to the lower connecting plate 36 at its bottom. As an intermediate structure connecting the outer connecting ring 32 and the lower connecting plate 36, the lower connecting piece 35 can transfer the supporting force of the outer connecting ring 32 to the lower connecting plate 36. At the same time, through its own length design, the lower connecting plate 36 is positioned at a height corresponding to the bottom of the tension control wheel, providing a suitable installation base for the subsequent contact between the pulley scraping assembly 38 and the tension control wheel. The lower connecting plate 36, which is fixedly connected to the bottom of the lower connecting piece 35, adopts a flat plate structure. Its top plane provides an installation platform for the dust collection assembly 37 and the pulley scraping assembly 38. The lower connecting plate 36 is connected to the outer connecting ring 32 through the lower connecting piece 35, indirectly obtaining the supporting force of the outer connecting ring 32, ensuring its own position is stable and will not be displaced due to vibration during device operation, thereby ensuring that the dust collection assembly 37 and the pulley scraping assembly 38 installed on it can always be in the set working position.
[0039] A dust collection assembly 37 is provided on the top rear side of the lower connecting plate 36. The inlet end of the dust collection assembly 37 is connected to the outlet end of the front dust suction pipe 34. Impurities transported by the front dust suction pipe 34 can directly enter the interior of the dust collection assembly 37. The interior of the dust collection assembly 37 is provided with a receiving cavity to store the incoming impurities and prevent them from directly scattering inside the device. At the same time, the dust collection assembly 37 can be disassembled and cleaned periodically to discharge the stored impurities and ensure its continuous collection capacity.
[0040] Reference Figure 1 , Figure 2 and Figure 4The static elimination mechanism 4 includes a lower connector 41. The top of the lower connector 41 is fixedly connected to the bottom of the positive and negative charge generator 2. A lower conductive plate 42 is fixedly connected to the bottom of the lower connector 41. A rear connecting plate 43 is fixedly connected to the rear side of the lower connector 41. A rear conductive plate 44 is fixedly connected to the rear side of the lower conductive plate 42. A rear connector 45 is fixedly connected to the rear side of the rear conductive plate 44. A grounding component 46 is provided at the bottom of the rear connector 45.
[0041] Specifically, when the device is started, the positive and negative charge generator 2 starts to operate. The charge it generates needs to be transferred to the static elimination mechanism 4 through a specific structure. The top of the lower connector 41 in the static elimination mechanism 4 is fixedly connected to the bottom of the positive and negative charge generator 2. The charge generated by the positive and negative charge generator 2 can be directly conducted through the lower connector 41. As the initial carrier of charge conduction, the lower connector 41 can stably receive the charge output by the positive and negative charge generator 2 and transfer it downward to the lower conductive plate 42.
[0042] The bottom of the lower connector 41 is fixedly connected to a lower conductive plate 42. The lower conductive plate 42 is made of conductive material and forms a continuous conductive path with the lower connector 41. The charge transferred from the lower connector 41 can smoothly enter the lower conductive plate 42. The planar structure of the lower conductive plate 42 can expand the distribution range of the charge and make the charge evenly dispersed on its surface, providing conditions for the subsequent action of the charge on the yarn. When the yarn passes near the lower conductive plate 42, the charge on the surface of the lower conductive plate 42 can interact with the static electricity on the surface of the yarn, initially neutralizing some of the static electricity on the surface of the yarn.
[0043] A rear connecting plate 43 is fixedly connected to the rear side of the lower connector 41. The rear connecting plate 43 can support the lower connector 41, enhance the stability of the connection between the lower connector 41 and the positive and negative charge generator 2, prevent the lower connector 41 from loosening due to vibration during device operation, and ensure the continuous smoothness of the charge conduction path. A rear conducting plate 44 is fixedly connected to the rear side of the lower conducting plate 42. The rear conducting plate 44 is also made of conductive material, and its surface area is larger than that of the lower conducting plate 42. The charges dispersed on the surface of the lower conducting plate 42 can be further transferred to the rear conducting plate 44. The rear conducting plate 44 can cover a wider area of yarn operation through its larger surface area. When the yarn passes near the rear conducting plate 44, the charges on the surface of the rear conducting plate 44 can make more full contact with the static electricity on the surface of the yarn. According to the polarity of the static electricity carried by different yarn materials, the opposite polarity charges generated by the positive and negative charge generator 2 will act on the yarn through the rear conducting plate 44 to achieve deep neutralization of the static electricity of the yarn and reduce the amount of static electricity remaining on the surface of the yarn.
[0044] A rear connector 45 is fixedly connected to the rear side of the rear conductive plate 44. The rear connector 45 serves as an intermediate structure connecting the rear conductive plate 44 and the grounding component 46, enabling a conductive connection between the rear conductive plate 44 and the grounding component 46. During the neutralization of yarn static electricity, the rear conductive plate 44 may accumulate some excess charge. If this excess charge accumulates on the surface of the rear conductive plate 44 for a long time, it will affect its neutralization efficiency for yarn static electricity. The rear connector 45 can transfer this excess charge to the grounding component 46, ensuring that the surface charge of the rear conductive plate 44 is always kept within a reasonable range and maintaining a stable static elimination capability. The grounding component 46 is provided at the bottom of the rear connector 45. The grounding component 46 is connected to the external grounding system. The excess charge transferred from the rear connector 45 can be conducted to the ground through the grounding component 46, completely eliminating the influence of excess charge on the static elimination mechanism 4. The grounding component 46 can also ensure the electrical safety of the entire static elimination mechanism 4, avoiding the risk of leakage due to charge accumulation, and ensuring that the device operates in a safe and stable state.
[0045] Throughout the operation of the static elimination mechanism 4, the functions of each component are closely interconnected. The lower connector 41 transfers charge from the positive and negative charge generator 2 to the lower conductive plate 42. The lower conductive plate 42 performs initial charge dispersion and initial neutralization of static electricity in the yarn. The rear connector 43 provides mounting support for the rear conductive plate 44 and enhances the stability of the lower connector 41. The rear conductive plate 44 further disperses charge and deeply neutralizes static electricity in the yarn. The rear connector 45 transfers excess charge from the rear conductive plate 44 to the grounding component 46. The grounding component 46 conducts excess charge into the ground. The components work together to form a complete static elimination process, ensuring that the yarn maintains a low static charge during tension adjustment. This prevents impurities from being attracted by static electricity from affecting yarn quality or causing a decrease in tension adjustment accuracy, thus ensuring the stable operation of the yarn tension controller.
[0046] Reference Figure 1 , Figure 2 and Figure 5The dust collection assembly 37 includes a collection box 371, the bottom of which is slidably connected to the top rear side of the lower connecting plate 36. A slide rail 372 is fixedly connected to the bottom right side of the collection box 371. The pulley scraping assembly 38 includes an inner connector 381, the bottom of which is slidably connected to the top rear side of the lower connecting plate 36. A dust scraping blade 382 is fixedly connected to the bottom right side of the inner connector 381. The grounding assembly 46 includes a lower quick-release ring 461, the bottom of which is slidably connected to the top rear side of the lower connecting plate 36. A grounding wire 462 is fixedly connected to the bottom right side of 1. A main support plate 5 is set at the bottom of the positive and negative charge generator 2. An upper connecting plate 6 is fixedly connected to the top rear side of the main support plate 5. Bottom anti-slip seats 7 are fixedly connected to the four corners of the bottom of the main support plate 5. A differential motor 8 is fixedly connected to the rear side of the upper connecting plate 6. A front connecting frame 9 is fixedly connected to the front side of the differential motor 8. An outer protective frame 10 is fixedly connected to the front side of the front connecting frame 9. A main rotating wheel 11 is rotatably connected to the upper inner side of the outer protective frame 10. A secondary rotating wheel 12 is rotatably connected to the lower inner side of the outer protective frame 10.
[0047] Specifically, the dust collection component 37 collects impurities during the operation of the self-cleaning mechanism 3. The collection box 371 serves as a storage carrier for impurities, and its bottom is slidably connected to the top rear side of the lower connecting plate 36. When the dust suction fan 31 transports impurities to the collection box 371 through the front dust suction pipe 34, the collection box 371 can centrally contain the impurities, preventing them from scattering inside the device. The slide rail 372, fixedly connected to the bottom right side of the collection box 371, is adapted to the pre-set slide groove on the top of the lower connecting plate 36. When the impurities inside the collection box 371 reach a certain amount, the operator can push the collection box 371 to slide on the lower connecting plate 36 via the slide rail 372, enabling quick disassembly and installation of the collection box 371. This facilitates timely cleaning of internal impurities and ensures the continuous collection capacity of the dust collection component 37. The wheel scraping assembly 38 works with the collection box 371 to clean impurities. The bottom of the inner connector 381 is slidably connected to the top rear side of the lower connecting plate 36. The position of the inner connector 381 on the lower connecting plate 36 can be adjusted by sliding to ensure that the structure connected at the top can maintain a suitable contact state with the yarn tension control wheel. The dust scraping blade 382 is fixedly connected to the bottom right side of the inner connector 381. When the yarn tension control wheel rotates, it contacts the bottom surface of the wheel. As the wheel rotates, the dust scraping blade 382 can scrape off the residual impurities of the yarn attached to the bottom of the wheel. Part of the scraped impurities fall directly into the collection box 371 below under the action of gravity, and the other part is attracted by the suction generated by the dust suction fan 31 and enters the collection box 371 through the front dust suction pipe 34, so as to achieve comprehensive collection of impurities.
[0048] The grounding component 46 completes the discharge of excess charge in the static elimination mechanism 4. The bottom of the lower quick-release ring 461 is slidably connected to the top rear side of the lower connecting plate 36. The position of the lower quick-release ring 461 can be adjusted by sliding to ensure that it can maintain a stable connection with the rear connecting piece 45. The grounding wire 462 is fixedly connected to the bottom right side of the lower quick-release ring 461. One end is connected to the lower quick-release ring 461, and the other end is connected to the external grounding system. The excess charge transmitted by the rear connecting piece 45 is introduced into the grounding wire 462 through the lower quick-release ring 461, and then into the ground through the grounding wire 462, completely eliminating the influence of excess charge on the static elimination mechanism 4, while ensuring the electrical safety of the device. The main support plate 5 set at the bottom of the positive and negative charge generator 2 provides stable support for the positive and negative charge generator 2 and avoids the positive and negative charge generator 2 from directly contacting other structures and causing positional displacement. The upper connecting plate 6 fixedly connected to the top rear side of the main support plate 5 provides a mounting carrier for the differential motor 8, so that the differential motor 8 can be in a position corresponding to the outer protective frame 10, ensuring the effective transmission of power of the differential motor 8.
[0049] The bottom anti-slip seats 7, fixedly connected to the four corners of the main support plate 5, are in direct contact with the placement surface. The bottom anti-slip seats 7 are made of a high-friction coefficient material, which increases the friction between the main support plate 5 and the placement surface, preventing overall displacement due to vibration during operation and ensuring the overall stability of the device. The differential motor 8, fixedly connected to the rear side of the upper connecting plate 6, provides rotational power to the main rotating wheel 11 and auxiliary rotating wheel 12 inside the outer protective frame 10. The front connecting frame 9, fixedly connected to the front side of the differential motor 8, connects the differential motor 8 to the outer protective frame 10, allowing the power generated by the differential motor 8 to be transmitted to the outer protective frame 10 through the front connecting frame 9, thereby driving the main rotating wheel 11 and auxiliary rotating wheel 12 to rotate. The fixedly connected outer protective frame 10 provides a wrap-around protection for the main rotating wheel 11 and the auxiliary rotating wheel 12, preventing external foreign objects from contacting the wheels and affecting their rotation. At the same time, it limits the rotation trajectory of the main rotating wheel 11 and the auxiliary rotating wheel 12, ensuring that their positions are stable during rotation. The main rotating wheel 11, which is rotatably connected to the upper inner side of the outer protective frame 10, and the auxiliary rotating wheel 12, which is rotatably connected to the lower inner side, rotate synchronously under the drive of the differential motor 8. The yarn is wound between the main rotating wheel 11 and the auxiliary rotating wheel 12, and the yarn is conveyed through their rotation. At the same time, the tension adjustment structure maintains the yarn tension stably. The rotation speed of the main rotating wheel 11 and the auxiliary rotating wheel 12 can be adjusted by the differential motor 8 to adapt to the conveying needs of yarns of different materials.
[0050] Working principle: In the self-cleaning function stage, after the rotary motor 1 starts, it drives the dust-collecting fan 31 to run, so that the dust-collecting fan 31 rotates continuously to generate a stable airflow suction force. This suction force acts on the engagement point of the yarn tension control wheel. At the same time, the outer connecting ring 32 provides external support for the dust-collecting fan 31 to prevent it from shifting during rotation, ensuring that the suction force accurately adsorbs impurities at the engagement point. The front protective frame 33 on the rear side of the dust-collecting fan 31 blocks foreign objects from entering and guides the airflow, so that the impurities are transported to the dust collection assembly 37 through the front dust-collecting pipe 34. The outer connecting ring 32 drives the lower connecting plate 36 to stabilize through the lower connecting piece 35. The pulley scraping assembly 38 on the lower connecting plate 36 contacts the bottom of the tension control wheel. As the wheel rotates, it scrapes away impurities from the bottom. The scraped impurities either fall into the dust collection assembly 37 or are sucked in by the dust suction fan 31 and then enter the collection assembly. Through the coordinated operation of the dust suction fan 31, the pulley scraping assembly 38, and the dust collection assembly 37, the impurities at the engagement point and bottom of the yarn tension control wheel are thoroughly cleaned. This prevents the wheel from jamming due to the accumulation of impurities, ensures the continuous and smooth rotation of the wheel, reduces the number of production line downtime maintenance, reduces production losses, and extends the service life of the equipment.
[0051] In the static elimination function implementation stage, the positive and negative charge generator 2 generates charges with opposite polarity to the yarn static electricity during operation. The charges are transferred to the lower conductive plate 42 through the lower connector 41. The lower conductive plate 42 expands the charge distribution range, performing preliminary static neutralization on the passing yarn. The rear connecting plate 43 behind the lower connector 41 enhances structural stability and supports the rear conductive plate 44. The lower conductive plate 42 further transfers the charges to the rear conductive plate 44. The rear conductive plate 44 covers the yarn running area with a larger surface area, performing deep static neutralization on the yarn. The rear conductive plate 44... 4. Excess charge is transferred to grounding component 46 through rear connector 45. After the lower quick-release ring 461 of grounding component 46 receives the charge, the excess charge is conducted to the ground through grounding wire 462. The process of generating reverse charge through positive and negative charge generator 2, neutralizing it step by step through lower conductive plate 42 and rear conductive plate 44, and discharging excess charge through grounding component 46 effectively eliminates static electricity during yarn tension adjustment, reduces the situation of static electricity adsorbing impurities, avoids yarn quality damage or decreased tension adjustment accuracy due to static electricity, and ensures stable yarn processing quality.
[0052] In the overall power and structural coordination process, the rotary motor 1 provides the power foundation for the positive and negative charge generator 2, which in turn provides power and charge support for the dust-collecting fan 31 and the static elimination mechanism 4, forming a linkage between power and function. The outer connecting ring 32, lower connecting piece 35, and lower connecting plate 36 of the self-cleaning mechanism 3 constitute a support system, which not only ensures the stable operation of the dust-collecting fan 31 and the pulley scraping assembly 38, but also provides an installation foundation for the grounding assembly 46. The lower connecting piece 41 and rear connecting plate 43 of the static elimination mechanism 4 form a structural connection with the lower connecting plate 36 of the self-cleaning mechanism 3, ensuring that each component is spatially compatible and functionally complementary. Through the power output of the rotary motor 1, the transfer of positive and negative charge generator 2, and the coordinated cooperation of the support structures of each mechanism, the synchronous operation of each component of the device is achieved, ensuring that the self-cleaning and static elimination functions act simultaneously on the yarn tension control process, avoiding equipment operation loopholes caused by single-function operation, and improving the overall working efficiency and stability of the device.
[0053] When the yarn enters the device for tension adjustment, the main rotor 11 and the auxiliary rotor 12 rotate under the drive of the differential motor 8, driving the yarn to be conveyed stably. At this time, the self-cleaning mechanism 3 continuously cleans impurities from the tension control wheel to prevent impurities from affecting the smoothness of yarn conveying. The static elimination mechanism 4 simultaneously eliminates static electricity from the yarn, preventing the yarn from becoming entangled or attracting impurities due to static electricity, ensuring that the yarn maintains a stable tension state during the conveying process. The main support plate 5 and the bottom anti-slip seat 7 ensure the overall stability of the device and prevent vibration from affecting the operating accuracy of each component. Through the synchronous operation of yarn conveying, self-cleaning, static elimination, and device support, multiple problems in the yarn tension adjustment process are solved simultaneously, ensuring continuous and stable yarn processing, and improving production efficiency and product qualification rate.
[0054] In the component maintenance and continuous operation phase, the slide rail 372 of the dust collection component 37 facilitates the quick disassembly and cleaning of the collection box 371, ensuring the continuous effectiveness of the impurity collection function; the lower quick-release ring 461 of the grounding component 46 facilitates the maintenance of the grounding wire 462, ensuring unobstructed charge discharge path; the structural design of each component not only meets the operational requirements but also reduces the difficulty of maintenance. Through convenient maintenance operations and stable operation of each component, the device can operate continuously for a long time, reducing downtime caused by maintenance, further improving the cost-effectiveness of the equipment, and meeting the long-term operation requirements of large-scale yarn processing production lines.
