Description

Technical Field

[0001] This invention relates to the field of polyester yarn production technology, specifically to a yarn doubling device for polyester yarn production. Background Technology

[0002] Polyester yarn, with its excellent properties such as high strength, abrasion resistance, wrinkle resistance, and easy care, is widely used in textiles, apparel, home textiles, and other fields, and market demand continues to rise. In the production process of polyester yarn, the doubling process is a crucial step. Its core is to combine multiple single-strand polyester yarns into one according to specific process requirements to improve the yarn's strength, toughness, and subsequent weaving performance, meeting the needs of different products. Therefore, the performance of the doubling device directly determines the production quality and efficiency of polyester yarn.

[0003] Currently, existing polyester yarn spinning devices still suffer from numerous technical defects that urgently need to be addressed in practical applications, making it difficult to meet the demands of modern, large-scale, high-quality polyester yarn production. Firstly, in terms of transmission structure design, existing devices mostly use a single drive method to operate some components, resulting in poor coordination between the various parts. This often leads to asynchronous issues in winding, yarn feeding, and placement table rotation, causing uneven tension among multiple yarns during spinning. This can easily result in overstretching, breakage, or loosening and tangling of the yarns, affecting spinning quality, reducing production continuity, and increasing production costs. Secondly, the transmission components of existing devices are mostly exposed, lacking effective protective structures, making them susceptible to corrosion from external dust and impurities. Furthermore, wear and tear during operation shortens equipment lifespan and increases maintenance costs. Summary of the Invention

The top of the top frame plate 2 is fixedly installed with a fixing plate 16. The drive motor 14 is fixedly installed on one side of the fixing plate 16. The top of the upright plate 1 and the top frame plate 2 are provided with rectangular grooves 18, and the limiting plate 17 is located inside the rectangular groove 18.

The outer side of each of the multiple placement inclined rollers 7 is fixedly installed with a bottom support plate 6. The bottom of the placement plate 5 is symmetrically fixedly installed with two placement arc blocks 54. The top of the rotating plate 31 is provided with two placement arc grooves 32.Two placement arc blocks 54 are snapped onto the inner sides of two placement arc grooves 32. The paralleling assembly includes a paralleling frame 21 and a paralleling ring 23. A paralleling seat 8 is fixedly installed at the end of the paralleling frame 21 away from the upright plate 1.

A support frame 22 is fixedly installed at the top of the paralleling frame 21. A paralleling cylinder 9 is fixedly installed at the end of the support frame 22 away from the paralleling frame 21. An anti-wear pad 10 is fixedly installed inside the paralleling cylinder 9.

[0028] The working principle of the above technical solution is as follows: First, yarn preparation is performed by placing multiple rolls of polyester yarn to be combined onto the multiple placement rollers 7 of the placement component. The placement rollers 7 are inclined to effectively prevent the yarn rolls from slipping during rotation. The bottom support plate 6 fixed on the outside of the rollers provides stable support and limits the bottom of the yarn rolls, preventing them from shifting. The placement plate 5 serves as the mounting carrier for the placement rollers 7. Through two symmetrically arranged placement arc blocks 54 at its bottom, it is precisely engaged with the inner sides of the two placement arc grooves 32 opened on the top of the rotating plate 31. This engagement structure not only achieves rapid positioning and installation of the placement component but also ensures the stability of the placement component on the rotating plate 31, preventing the placement component from shaking when the rotating plate 31 rotates. This facilitates subsequent... The smooth delivery of yarn lays the foundation. After the material preparation is completed, the drive motor 14 in the drive assembly is started. The drive motor 14 is fixedly installed on one side of the fixing plate 16 on the top of the top frame plate 2. The fixing plate 16 provides a stable installation support for the drive motor 14 and prevents violent shaking during motor operation. After the drive motor 14 starts, its output end drives the take-up mounting roller 19 to rotate synchronously. The limiting plate 17, which is symmetrically fixed on the outside of the take-up mounting roller 19, is located exactly inside the rectangular groove 18 opened on the top of the upright plate 1 and the top frame plate 2. The limiting plate 17 can effectively prevent the yarn after bundling from shifting to both sides during the take-up process, ensuring that the yarn is neatly taken up. At the same time, the take-up mounting groove 20 opened on the outside of the take-up mounting roller 19 is used for precise installation of the take-up sleeve. The take-up sleeve and the take-up mounting groove 20. The sleeve is fitted to ensure no slippage during winding, preparing for subsequent yarn winding after bundling. As the winding mounting roller 19 rotates, the transmission wheel 52 fixedly mounted on its outer side rotates synchronously. The transmission wheel 52, through the transmission belt 15 sleeved on its outer side, drives the transmission wheel 49, located away from the transmission wheel 52, to rotate. Since the transmission wheel 49 is fixedly mounted inside the rotating rod 45, it drives the rotating rod 45 to rotate smoothly within the transmission groove 38. When the rotating rod 45 rotates, the transmission wheel 47 fixedly mounted on its outer side rotates synchronously. The transmission wheel 47, through the transmission belt 48, drives the transmission wheel 50 to rotate. The transmission wheel 50 is fixedly connected to the rotating rod 51, thus driving the rotating rod 51 to rotate within the transmission groove 38. Two symmetrically fixed abutting protrusion wheels 53 on the outer side of the rotating rod 51 rotate synchronously with the rotating rod 2 51, providing power for the operation of the subsequent reciprocating auxiliary components. At the same time, the transmission wheel 46 on the rotating rod 1 45 drives the transmission wheel 35 to rotate through the transmission belt 3 44 sleeved on the outer side. The rotating rod 3 34 fixedly installed inside the transmission wheel 6 35 rotates accordingly. The worm 36 fixed at one end of the rotating rod 3 34 meshes with the worm wheel 33. When the worm 36 rotates, it drives the worm wheel 33 to rotate synchronously. The driving gear 43 fixed at the bottom of the worm wheel 33 rotates accordingly. The driving gear 43 meshes with the transmission gear 42 and the rotating gear 41 in sequence, and finally drives the rotating plate 31 fixedly connected to the top of the rotating gear 41 to rotate inside the frustum plate 4, realizing the synchronous rotation of the placement components.To ensure even tension on the yarn, when the two abutting protrusion wheels 53 on the second moving rod 51 rotate, their abutting ends alternately abut against the airbag pressure plate 62 inside the top frame plate 2. The top frame plate 2 has two symmetrically arranged circular swing grooves 28, corresponding to the positions of the two abutting protrusion wheels 53, providing space for the rotation of the abutting protrusion wheels 53 and the movement of the airbag pressure plate 62. Multiple polyester yarns on the placement assembly slowly rotate under the drive of the rotating plate 31, maintaining uniform tension on each yarn. Then, each yarn is passed through the doubling groove 25 of the doubling ring 23 in the doubling assembly. The number of yarn-combining grooves 25 is consistent with the number of inclined rollers 7, ensuring that each yarn can accurately enter the corresponding yarn-combining groove 25, achieving initial yarn-combining and avoiding misalignment or confusion during yarn-combining. The yarn-combining ring 23 is precisely engaged with the mounting pin 55 fixedly installed at the bottom, which is then precisely locked into the mounting hole 29 on the top of the rotating ring 30. This locking structure facilitates quick disassembly and replacement of the yarn-combining ring 23, allowing for the replacement of different specifications of yarn-combining rings 23 according to yarn-combining requirements. The rotating ring 30 is rotatably mounted inside the yarn-combining base 8, while the yarn-combining base 8 is fixedly mounted on the yarn-combining frame 21. At the end furthest from the upright plate 1, the rotating ring 30 can rotate flexibly to adapt to angle changes during yarn feeding, reducing friction between the yarn and the doubling ring 23. The initially doubled yarn continues to pass through the doubling spool 9 at the end of the support frame 22 fixedly installed at the top of the doubling frame 21. The anti-wear pad 10 fixed inside the doubling spool 9 is made of a soft and wear-resistant material, effectively reducing friction loss when the yarn passes through the doubling spool 9. Simultaneously, it further combs and integrates the initially doubled yarn, making the doubled yarn more uniform and compact. After completing the entire doubling process, the yarn... The polyester yarn, after being plied, smoothly enters the reciprocating U-shaped frame 60, preparing for subsequent winding. Emerging from the reciprocating U-shaped frame 60, it is precisely wound onto the winding sleeve outside the winding mounting roller 19. As the winding mounting roller 19 rotates continuously and uniformly under the drive of the drive motor 14, the plied yarn is wound in an orderly manner. During the winding process, the limiting plate 17 on the outside of the winding mounting roller 19 always acts as a limiter, preventing yarn deviation and loosening, ensuring that the wound yarn is neat and standardized. The entire plied yarn process is automated and requires minimal manual intervention.

[0029] In another implementation scheme, such as Figures 1-9As shown, the reciprocating auxiliary assembly includes an inner sleeve 12. Both ends of the inner sleeve 12 are fixedly installed inside the top frame plate 2 at the end furthest from the upright plate 1. A moving groove 11 is provided inside the inner sleeve 12. An inner slider 40 is slidably installed inside the moving groove 11. An outer slip ring 39 is fixedly installed on the outer side of the inner slider 40. Pneumatic telescopic rods 37 are fixedly connected to both ends of the inner slider 40. An elastic airbag 61 is connected to the end of each pneumatic telescopic rod 37 furthest from the inner slider 40 via a pipe. A reciprocating U-shaped frame 60 is fixedly installed on the outer side of the outer slip ring 39. A sealing arc block 58 is movably installed inside the reciprocating U-shaped frame 60. An arc-shaped sliding section is provided at the top of the reciprocating U-shaped frame 60. The top of the sealing arc block 58 is fixedly installed with an arc-shaped slider 57, and the top of the arc-shaped slider 57 is fixedly installed with a push block 56. The arc-shaped slider 57 is slidably installed on the inner side of the arc-shaped groove 59. Two elastic airbags 61 are symmetrically installed on both sides of the inner cavity of the top frame plate 2. One end of each elastic airbag 61 is fixedly installed with an airbag pressure plate 62, and the two airbag pressure plates 62 correspond to the positions of the two abutting protrusion wheels 53 respectively. The interior of the top frame plate 2 is symmetrically provided with circular swing grooves 28, and the two circular swing grooves 28 correspond to the positions of the two abutting protrusion wheels 53 respectively. An arc-shaped block 13 is fixedly installed at the end of the top frame plate 2 away from the upright plate 1.

[0030] When the contact end of the contacting cam wheel 53 presses against the airbag pressure plate 62, it will push the corresponding elastic airbag 61 to contract. The elastic airbag 61 transmits pressure to the pneumatic telescopic rod 37 through the pipe, causing the pneumatic telescopic rod 37 to extend and retract, thereby pushing the inner slider 40 to reciprocate within the moving groove 11 of the inner sleeve 12. The two ends of the inner sleeve 12 are fixedly installed inside the top frame plate 2 away from the upright plate 1, providing stable guidance for the sliding of the inner slider 40. When the inner slider 40 slides, the outer slip ring 39 fixed on its outer side moves synchronously, thereby driving the reciprocating U-shaped... The frame 60 reciprocates, and the reciprocating U-shaped frame 60 is used to carry the yarn after it has been plied. At the same time, the sealing arc block 58 slides flexibly in the arc-shaped groove 59 opened at the top of the reciprocating U-shaped frame 60 through the arc-shaped slider 57 fixed at the top, effectively sealing the opening of the reciprocating U-shaped frame 60 and completely preventing the polyester yarn that has been plied inside the reciprocating U-shaped frame 60 from coming out. Afterwards, the yarn is guided by the arc-shaped block 13 fixedly installed at the end of the top frame plate 2 away from the vertical frame plate 1, and then smoothly enters the subsequent winding process, further ensuring the smoothness of the yarn conveying process and avoiding the problem of yarn tangling or coming out.

[0031] In another implementation scheme, such as Figures 1-9 As shown, a support platform 27 is fixedly installed at the bottom of the frustum plate 4, and two support legs 26 are fixedly installed symmetrically at the bottom of the upright plate 1 and the base plate 3.

[0032] The support platform 27 fixedly installed at the bottom of the circular platform 4, and the two support legs 26 symmetrically fixedly installed at the bottom of the upright plate 1 and the base plate 3, together provide stable support for the whole device, effectively preventing shaking and deviation during device operation, and ensuring that the entire winding and coiling process continues stably until a batch of polyester yarn is produced.

[0033] Working Principle: First, yarn preparation is performed. Multiple rolls of polyester yarn to be combined are placed on the various inclined rollers 7 of the placement assembly. The inclined rollers 7 are tilted to effectively prevent the yarn rolls from slipping during rotation. The base plate 6 fixed to the outside of the rollers provides stable support and limits the bottom of the yarn rolls, preventing them from shifting. The placement plate 5 serves as the mounting carrier for the inclined rollers 7. Two symmetrically arranged placement arc blocks 54 on its bottom precisely engage with the inner sides of the two placement arc grooves 32 on the top of the rotating plate 31. This engaging structure not only enables rapid positioning and installation of the placement assembly but also ensures the stability of the placement assembly on the rotating plate 31, preventing shaking of the placement assembly during subsequent rotation of the rotating plate 31, thus laying the foundation for smooth yarn feeding. After the foundation is laid and materials are prepared, the drive motor 14 in the drive assembly is started. The drive motor 14 is fixedly mounted on one side of the fixing plate 16 on the top of the top frame plate 2. The fixing plate 16 provides a stable mounting support for the drive motor 14, preventing violent shaking during operation. After the drive motor 14 starts, its output end drives the take-up mounting roller 19 to rotate synchronously. The limiting plates 17 symmetrically fixed on the outside of the take-up mounting roller 19 are precisely located inside the rectangular slots 18 opened on the top of the upright plate 1 and the top frame plate 2. The limiting plates 17 effectively prevent the yarn after bundling from shifting to both sides during the take-up process, ensuring neat yarn take-up. Simultaneously, the take-up mounting groove 20 opened on the outside of the take-up mounting roller 19 is used for precise installation of the take-up sleeve. The take-up sleeve fits into the take-up mounting groove 20, ensuring... During the winding process, the sleeve does not slip, ensuring adequate preparation for subsequent yarn winding after bundling. As the winding mounting roller 19 rotates, the drive wheel 52 fixedly mounted on its outer side rotates synchronously. Drive wheel 52, via the drive belt 15 sleeved on its outer side, drives drive wheel 49, located away from drive wheel 52, to rotate. Since drive wheel 49 is fixedly mounted inside rotating rod 45, it drives rotating rod 45 to rotate smoothly within the transmission groove 38. When rotating rod 45 rotates, drive wheel 47 fixedly mounted on its outer side rotates synchronously. Drive wheel 47, via the drive belt 48, drives drive wheel 50 to rotate. Drive wheel 50 is fixedly connected to rotating rod 51, thus driving rotating rod 51 to rotate within the transmission groove 38. Rotating rod 51 is symmetrically fixed on its outer side. The two abutting protrusion wheels 53 rotate synchronously with the rotating rod 51, providing power for the operation of the subsequent reciprocating auxiliary components. Simultaneously, the transmission wheel 46 on the rotating rod 45 drives the transmission wheel 35 to rotate via the transmission belt 44 sleeved on its outer side. The rotating rod 34, fixedly installed inside the transmission wheel 35, rotates accordingly. The worm 36 fixed at one end of the rotating rod 34 meshes with the worm wheel 33. When the worm 36 rotates, it drives the worm wheel 33 to rotate synchronously. The driving gear 43 fixed at the bottom of the worm wheel 33 rotates accordingly. The driving gear 43 meshes with the transmission gear 42 and the rotating gear 41 in sequence, ultimately driving the rotating plate 31 fixedly connected to the top of the rotating gear 41 to rotate inside the frustum plate 4, achieving synchronous rotation of the placement components and ensuring uniform force on the yarn.When the two abutting protrusion wheels 53 on the second moving rod 51 rotate, their abutting ends alternately abut against the airbag pressure plate 62 inside the top frame plate 2. The top frame plate 2 has two symmetrically arranged circular swing grooves 28, corresponding to the positions of the two abutting protrusion wheels 53, providing space for the rotation of the abutting protrusion wheels 53 and the movement of the airbag pressure plate 62. When the abutting ends of the abutting protrusion wheels 53 press against the airbag pressure plate 62, they push the corresponding elastic airbag 61 to contract. The elastic airbag 61 transmits pressure to the pneumatic telescopic rod 37 through a pipe, causing the pneumatic telescopic rod 37 to extend and retract, thereby pushing the inner slider 40 to reciprocate within the moving groove 11 of the inner sleeve 12. The two ends of the inner sleeve 12 are fixedly installed inside the top frame plate 2 at the end away from the upright plate 1, providing space for the inner slider 40. The sliding of the inner slider 40 provides stable guidance. When the inner slider 40 slides, the outer sliding ring 39 fixed on its outer side moves synchronously, thereby driving the reciprocating U-shaped frame 60 fixed on the outer side of the outer sliding ring 39 to reciprocate. The reciprocating U-shaped frame 60 is used to carry the yarn after it has been plied. At the same time, the sealing arc block 58 slides flexibly in the arc groove 59 opened at the top of the reciprocating U-shaped frame 60 through the arc-shaped slider 57 fixed at the top, effectively sealing the opening of the reciprocating U-shaped frame 60 and completely preventing the polyester yarn that has been plied inside the reciprocating U-shaped frame 60 from coming out. Afterwards, the yarn is guided by the arc-shaped block 13 fixedly installed at the end of the top frame plate 2 away from the vertical frame plate 1, and then smoothly enters the subsequent winding process, further ensuring the smoothness of the yarn conveying process and avoiding the problem of yarn tangling or coming out. Multiple polyester yarns on the assembly rotate slowly under the drive of the rotating plate 31, ensuring uniform tension in each yarn. Each yarn is then passed through the corresponding doubling groove 25 of the doubling ring 23 in the doubling assembly. The number of doubling grooves 25 matches the number of inclined rollers 7, ensuring each yarn accurately enters its corresponding groove 25, achieving initial doubling of multiple yarns and preventing misalignment or confusion during doubling. The doubling ring 23 is precisely engaged with the mounting hole 29 on the top of the rotating ring 30 via a fixed mounting post 55 at the bottom. This engagement structure facilitates quick disassembly and replacement of the doubling ring 23, allowing for the replacement of different specifications of doubling rings 23 according to doubling requirements. The rotating ring 30 is rotatably mounted inside the doubling base 8, while the doubling... The yarn holder 8 is fixedly installed at the end of the yarn-combining frame 21 away from the upright plate 1. The rotating ring 30 can rotate flexibly to adapt to the angle changes during yarn feeding, reducing friction between the yarn and the yarn-combining ring 23. After initial yarn combination, the yarn continues to pass through the yarn-combining spool 9 at the end of the support frame 22 fixedly installed at the top of the yarn-combining frame 21. The anti-wear pad 10 fixed inside the yarn-combining spool 9 is made of soft and wear-resistant material, which can effectively reduce friction loss when the yarn passes through the yarn-combining spool 9. At the same time, it plays a further combing and integrating role for the initially combined yarn, making the combined yarn more uniform and compact. After completing the entire yarn-combining process, the yarn smoothly enters the reciprocating U-shaped frame 60, preparing for subsequent winding. After the polyester yarn is processed by yarn combination, it comes out of the reciprocating U-shaped frame 60.The yarn is precisely wound onto the take-up sleeve outside the take-up mounting roller 19. As the take-up mounting roller 19 rotates continuously and uniformly under the drive of the drive motor 14, the yarn is orderly wound after being plied. During the winding process, the limiting plate 17 on the outside of the take-up mounting roller 19 always acts as a limiter, preventing the yarn from shifting or loosening during winding, ensuring that the wound yarn is neat and standardized. The entire pliing process is automated and requires minimal manual intervention. The support platform 27 fixedly installed at the bottom of the frustum plate 4, and the two support legs 26 symmetrically fixedly installed at the bottom of the upright plate 1 and the base plate 3, together provide stable support for the entire device, effectively preventing shaking or shifting during operation, ensuring the continuous and stable operation of the entire pliing and winding process until a batch of polyester yarn is produced.
