Description

Technical Field

[0001] This invention relates to the field of texturing wire processing technology, specifically to a texturing wire elastic traction device. Background Technology

[0002] Texturizing synthetic fibers involves using a "false twist" technique to create a certain degree of bending in polyester or polypropylene filaments. When subjected to external force, the false twist opens, causing elongation; when the force is removed, the false twist returns to its original position, giving the fiber a certain degree of resilience. Essentially, texturizing synthetic fibers involves bending them and then heating and setting them. When the fibers are straightened and released, they bend again, exhibiting elasticity. The traction roller is one of the most commonly used mechanical components in textile machinery, primarily used to traction the woven yarn. It typically consists of two rollers: a drive roller and a pressure roller. The drive roller and pressure roller are in close contact, allowing the woven yarn to... The yarn is transferred between the drive roller and the pressure roller. During the stretching and tightening process of the texturing machine, the yarn continues to advance through the feeding roller. The subsequent process also pulls the yarn to generate a pre-tensioning force. The yarn is driven forward by the pressing and rotating of the roller on the roller. If the pulling force of the downstream or upstream process is too large, exceeding the friction and rotation speed of the roller, the yarn will be pulled and slipped. When the yarn is pulled and slipped, it is not stretched to the proper position. As a result, the twisted elastic yarn does not obtain sufficient elasticity, causing the yarn to become stiff and lack elasticity.

[0003] Existing elastic traction devices for textured yarns have structural design flaws. These flaws include the problem that the friction between the untwisted yarn and the guide wheel can cause excessive yarn resistance and breakage, and that the twisted elastic yarn does not obtain sufficient elasticity, resulting in yarn stiffness. Summary of the Invention

[0004] The present invention provides an elastic traction device for elasticized yarn, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elastic traction device for elasticated wires, comprising...

[0006] A base, the top of which is fixedly connected to a cabinet;

[0007] An anti-deposition mechanism is located on the upper part of the inner side of the cabinet. An adjustment component is fixedly connected to the inner side of the cabinet. There are two adjustment components, which are symmetrically distributed around the anti-deposition mechanism. The adjustment components guide the untwisted yarn, which is wound around the surface of the anti-deposition mechanism. A rotating component is also included. A tube is fixedly connected to the inner side of the rotating component. A winding component is fixedly connected to the surface of the tube. The winding component winds the untwisted yarn, and the lint generated by the friction of the untwisted yarn is discharged through the tube.

[0008] An anti-stiffness mechanism is located on the lower side of the inner side of the cabinet. The anti-stiffness mechanism winds and collects the untwisted yarn. Both the anti-stiffness mechanism and the winding assembly are equipped with rotational power to drive them to rotate. The untwisted yarn is pulled and stretched between the anti-stiffness mechanism and the winding assembly to complete the texturing process.

[0009] Preferably, the adjusting component includes a slide rail, the surface of which is fixedly connected to the upper part of the inner side of the cabinet, a slide table slidably connected to the inner side of the slide rail, a support plate fixedly connected to the surface of the slide table, and rollers rotatably connected to the inner side of the support plate. One end of the untwisted yarn is fixedly connected to the surface of the anti-stiffness mechanism, which pulls and winds the untwisted yarn. The slide table slides on the inner side of the slide rail, and the adjusting component arranged opposite to it guides the untwisted yarn.

[0010] Preferably, the rotating assembly includes a housing, the surface of which is fixedly connected to the upper part of the cabinet surface, and a fixing cylinder is fixedly connected to the side of the housing surface away from the cabinet.

[0011] Preferably, an air outlet is provided at the upper position of the fixed cylinder surface, and a worm gear is rotatably connected at the middle position of the inner side of the housing. The inner side of the worm gear is fixedly connected to the tube surface near the end face. The horizontal distance between the roller and the component housing is adjustable. The untwisted yarn passes through the roller at the upper position, and then the untwisted yarn is spirally wound on the surface of the component housing. The spiral groove provides support for the winding of the untwisted yarn.

[0012] Preferably, the winding assembly includes an assembly shell, the two ends of which are fixedly connected to the surface of the tube, and the interior of the tube communicates with the interior of the assembly shell.

[0013] Preferably, the surface of the component housing is provided with a spiral groove, a flow hole is provided on the surface of the component housing near the spiral groove, and a retaining ring is fixedly connected to the surface of the component housing near the end face.

[0014] Preferably, the anti-stiffness mechanism includes a driving component, the surface of which is fixedly connected to the lower part of the inner side of the cabinet, a connecting rod is slidably connected to the inner side of the driving component, and a toothed surface is formed on the surface of the connecting rod. The untwisted yarn is spring-loaded between the winding component and the traction component. The first motor drives the rotating rod to rotate, and the traction component is driven to rotate by the rotating rod. The traction component pulls and winds one end of the untwisted yarn.

[0015] Preferably, a first motor is fixedly connected to the end of the connecting rod away from the driving component, a rotating rod is fixedly connected to the output end of the first motor, and a traction component is sleeved on the surface of the rotating rod.

[0016] Preferably, the driving component includes a support wall, and a sleeve is fixedly connected to the middle of the inner side of the support wall. The inner side of the sleeve is slidably connected to the surface of the connecting rod. The sleeve supports the connecting rod. The second motor drives the gear to rotate. The rotation of the gear causes the connecting rod to move away from the support wall, thereby adjusting the horizontal distance between the winding drum and the winding component.

[0017] Preferably, a second motor is fixedly connected to the surface of the support wall, and a gear is fixedly connected to the output end of the second motor, the surface of the gear meshing with the surface of the connecting rod.

[0018] Preferably, the traction assembly includes a rubber bladder, the inner side of which is fitted onto the surface of the connecting rod, and a spool is fitted onto the surface of the rubber bladder. The untwisted yarn is guided vertically downward by rollers. During installation, multiple spools slide into the surface of the rotating rod. After the spools are arranged, one end of the untwisted yarn passes through the limiting hole.

[0019] Preferably, a limiting hole is formed on the surface of the winding drum, and a limiting rod is fixedly connected to the inner side of the winding drum. One end of the untwisted yarn passes through the limiting hole. Subsequently, hydraulic pressure is injected into the inside of the rubber bladder to fix the untwisted yarn to the winding drum.

[0020] This invention provides an elastic traction device for elasticized yarn. It has the following beneficial effects:

[0021] 1. In this elastic traction device for textured yarn, the diameter of the roller is the same as the diameter of the winding assembly. The untwisted yarn passes through the roller, the winding assembly and the roller in sequence, so that the untwisted yarn is wound on the surface of the winding assembly. Gas flows inside the tube to remove the lint on the surface of the untwisted yarn through the flow of gas, so as to avoid the lint getting stuck inside the rotating assembly. This solves the problem that the lint generated by the contact friction between the untwisted yarn and the guide wheel will cause the yarn to break due to excessive resistance.

[0022] 2. In this elastic traction device for textured yarn, the horizontal distance between the opposing rollers determines the number of turns of the untwisted yarn on the surface of the component housing. The worm gear rotates under the drive of the worm, and the rotation of the worm gear causes the tube to rotate. An air pump is connected to the air outlet, which allows the airflow to circulate inside the tube. The lint on the surface of the untwisted yarn enters the tube through the flow hole. With the flow of gas, the lint is guided to the fixed cylinder, and then the lint is discharged through the air outlet.

[0023] 3. In this elastic traction device for elastic yarn, the rotating component drives the tube to rotate, and the untwisted yarn is spirally wound on the surface of the winding component under the drive of the roller, thereby increasing the rotational resistance of the untwisted yarn on the surface of the winding component. A rotational speed difference is set between the winding component and the traction component. This rotational speed difference causes the untwisted yarn to be stretched and elastic between the winding component and the traction component, which solves the problem that the twisted elastic yarn does not obtain sufficient elasticity and the yarn becomes stiff.

[0024] 4. In this elastic traction device for the textured yarn, the untwisted yarn is vertically downward, with one end of the untwisted yarn extending into the inside of the winding drum. Hydraulic pressure is introduced into the inside of the rubber bladder, which fixes the winding drum and the rotating rod, and at the same time fixes the untwisted yarn in place. The sliding of the connecting rod, in conjunction with the rotation of the first motor, prevents the untwisted yarn from being unevenly wound on the surface of the winding drum, thus preventing the untwisted yarn from slipping, failing to be textured, and the yarn from becoming stiff.

[0025] 5. In this elastic traction device for the textured yarn, hydraulic pressure is introduced into the rubber bladder. The hydraulic pressure causes the rubber bladder to expand, which limits the winding drum and one end of the untwisted yarn. The untwisted yarn is wound at the position of the spiral groove. The more turns the untwisted yarn is wound, the more the component housing and the winding drum are powered to rotate. The difference in rotation speed causes the untwisted yarn to be stretched to complete the texturing process. When the component housing and the winding drum rotate, the untwisted yarn is less likely to unwind, thus making the anti-stiffness effect of the untwisted yarn better. Attached Figure Description

[0035] 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.

[0036] like Figures 1-3 As shown, the present invention provides a technical solution: an elastic traction device for elasticized wire, comprising...

[0037] Base 1, with cabinet 2 fixedly connected to the top of base 1;

[0038] The anti-deposition mechanism 4 is located above the inner side of the cabinet 2. An adjustment component 3 is fixedly connected to the inner side of the cabinet 2. There are two adjustment components 3, which are symmetrically distributed around the anti-deposition mechanism 4. The adjustment component 3 guides the untwisted yarn, which is wound around the surface of the anti-deposition mechanism 4. The mechanism also includes a rotating component 41, with a tube 42 fixedly connected to the inner side of the rotating component 41. A winding component 43 is fixedly connected to the surface of the tube 42. The winding component 43 winds the untwisted yarn, and oil stains and lint on the surface of the untwisted yarn are removed through the tube 42.

[0039] The adjustment component 3 includes a slide rail 31, the surface of which is fixedly connected to the upper part of the inner side of the cabinet 2. A slide table 32 is slidably connected to the inner side of the slide rail 31. A support plate 33 is fixedly connected to the surface of the slide table 32. A roller 34 is rotatably connected to the inner side of the support plate 33.

[0040] The anti-stiffness mechanism 5 is located at the lower part of the inner side of the cabinet 2. The anti-stiffness mechanism 5 winds and collects the untwisted yarn. Both the anti-stiffness mechanism 5 and the winding assembly 43 are equipped with rotational power to drive them to rotate. The untwisted yarn is pulled and stretched between the anti-stiffness mechanism 5 and the winding assembly 43 to complete the texturing process.

[0041] In use, one end of the untwisted yarn is fixedly connected to the surface of the anti-stiffness mechanism 5. The anti-stiffness mechanism 5 pulls and winds the untwisted yarn. The slide table 32 slides on the inner side of the slide rail 31. The opposing adjustment component 3 guides the untwisted yarn. The diameter of the roller 34 is the same as the diameter of the winding component 43. The untwisted yarn passes through the roller 34, the winding component 43 and the roller 34 in sequence, so that the untwisted yarn is wound on the surface of the winding component 43. Gas flows inside the tube 42 to remove the lint on the surface of the untwisted yarn through the flow of gas, avoiding the lint from getting stuck inside the rotating component 41. This solves the problem that the lint generated by the contact friction between the untwisted yarn and the guide wheel will cause the yarn to break due to excessive resistance.

[0042] like Figure 3 , Figure 4 , Figure 5 As shown, the rotating assembly 41 includes a housing 411, the surface of which is fixedly connected to the upper part of the surface of the cabinet 2. A fixed cylinder 413 is fixedly connected to the side of the housing 411 away from the cabinet 2. An air outlet 414 is provided at the upper part of the surface of the fixed cylinder 413. A worm gear 412 is rotatably connected to the middle part of the inner side of the housing 411. The inner side of the worm gear 412 is fixedly connected to the surface of the tube 42 near the end face. The winding assembly 43 includes an assembly shell 431, the two ends of which are fixedly connected to the surface of the tube 42. The interior of the tube 42 communicates with the interior of the assembly shell 431. A spiral groove 433 is provided on the surface of the assembly shell 431. A flow hole 434 is provided on the surface of the assembly shell 431 near the spiral groove 433. A retaining ring 432 is fixedly connected to the surface of the assembly shell 431 near the end face.

[0043] In use, the horizontal distance between the roller 34 and the component housing 431 is adjustable. The untwisted yarn passes through the upper roller 34 and then spirally winds around the surface of the component housing 431. The spiral groove 433 provides support for the winding of the untwisted yarn. The horizontal distance between the opposing rollers 34 determines the number of turns of the untwisted yarn on the surface of the component housing 431. The worm gear 412 rotates under the drive of the worm. The rotation of the worm gear 412 causes the tube body 42 to rotate. The air outlet 414 is connected to an external air pump, which allows airflow to circulate inside the tube body 42. The lint on the surface of the untwisted yarn enters the tube body 42 through the flow hole 434. With the flow of gas, the lint is guided to the fixed cylinder 413, and then the lint is discharged through the air outlet 414.

[0044] like Figure 3 , Figure 6 As shown, a tube 42 is fixedly connected to the inner side of the rotating component 41, and a winding component 43 is fixedly connected to the surface of the tube 42. The winding component 43 winds the untwisted yarn, and the oil and lint on the surface of the untwisted yarn are discharged through the tube 42.

[0045] The adjustment component 3 includes a slide rail 31, the surface of which is fixedly connected to the upper part of the inner side of the cabinet 2. A slide table 32 is slidably connected to the inner side of the slide rail 31. A support plate 33 is fixedly connected to the surface of the slide table 32. A roller 34 is rotatably connected to the inner side of the support plate 33. The anti-stiffness mechanism 5 includes a drive component 51, the surface of which is fixedly connected to the lower part of the inner side of the cabinet 2. A connecting rod 52 is slidably connected to the inner side of the drive component 51. A rack surface 53 is provided on the surface of the connecting rod 52. A second motor 54 is fixedly connected to the end of the connecting rod 52 away from the drive component 51. A rotating rod 55 is fixedly connected to the output end of the second motor 54. A traction component 56 is sleeved on the surface of the rotating rod 55.

[0046] In use, the untwisted yarn is spring-loaded between the winding assembly 43 and the traction assembly 56. The second motor 54 drives the rotating rod 55 to rotate, and the traction assembly 56 is driven to rotate by the rotating rod 55. The traction assembly 56 pulls and winds one end of the untwisted yarn. The rotating assembly 41 drives the tube 42 to rotate. The untwisted yarn is spirally wound on the surface of the winding assembly 43 by the roller 34, thereby increasing the rotational resistance of the untwisted yarn on the surface of the winding assembly 43. A rotational speed difference is set between the winding assembly 43 and the traction assembly 56. This rotational speed difference causes the untwisted yarn to be stretched and elastic between the winding assembly 43 and the traction assembly 56, which solves the problem that the twisted elastic yarn does not obtain enough elasticity, resulting in stiff yarn.

[0047] like Figure 6 , Figure 7 , Figure 8 As shown, the driving component 51 includes a support wall 511, a sleeve 512 is fixedly connected to the middle of the inner side of the support wall 511, the inner side of the sleeve 512 is slidably connected to the surface of the connecting rod 52, a first motor 513 is fixedly connected to the surface of the support wall 511, a gear 514 is fixedly connected to the output end of the first motor 513, and the surface of the gear 514 meshes with the surface of the connecting rod 52. The traction component 56 includes a rubber bladder 561, the inner side of the rubber bladder 561 is sleeved on the surface of the connecting rod 52, a winding drum 562 is sleeved on the surface of the rubber bladder 561, a limiting hole 563 is opened on the surface of the winding drum 562, a limiting rod 564 is fixedly connected to the inner side of the winding drum 562, one end of the untwisted wire passes through the limiting hole 563, and then hydraulic pressure is injected into the inside of the rubber bladder 561 to fix the untwisted wire to the winding drum 562.

[0048] In use, the sleeve 512 supports the connecting rod 52. The first motor 513 drives the gear 514 to rotate. The rotation of the gear 514 causes the connecting rod 52 to move away from the support wall 511, thereby adjusting the horizontal distance between the winding drum 562 and the winding assembly 43. The untwisted yarn is vertically downward, and one end of the untwisted yarn extends into the inside of the winding drum 562. Hydraulic pressure is introduced into the inside of the rubber bladder 561. The hydraulic pressure fixes the winding drum 562 and the rotating rod 55, and at the same time fixes the untwisted yarn in place by the winding drum 562. The sliding of the connecting rod 52, in conjunction with the rotation of the second motor 54, drives the rotation to prevent the untwisted yarn from being unevenly wound on the surface of the winding drum 562, which could cause the untwisted yarn to slip, fail to spring back, or become stiff.

[0049] like Figure 5 , Figure 8 As shown, the two ends of the component housing 431 are fixedly connected to the surface of the tube body 42. The interior of the tube body 42 is connected to the interior of the component housing 431. The surface of the component housing 431 is provided with a spiral groove 433. A flow hole 434 is provided on the surface of the component housing 431 near the spiral groove 433. A retaining ring 432 is fixedly connected to the surface of the component housing 431 near the end face. The inner side of the rubber bladder 561 is sleeved on the surface of the connecting rod 52. A winding drum 562 is sleeved on the surface of the rubber bladder 561. A limiting hole 563 is provided on the surface of the winding drum 562. A limiting rod 564 is fixedly connected to the inner side of the winding drum 562. One end of the untwisted wire passes through the limiting hole 563. Then, hydraulic pressure is injected into the interior of the rubber bladder 561 to fix the untwisted wire to the winding drum 562.

[0050] During use, the untwisted yarn is guided vertically downward by the roller 34. During installation, multiple spools 562 slide into the surface of the rotating rod 55. After the spools 562 are arranged, one end of the untwisted yarn passes through the limiting hole 563. Hydraulic pressure is introduced into the rubber bladder 561, which causes the rubber bladder 561 to expand, thus limiting the spools 562 and one end of the untwisted yarn. The untwisted yarn is wound at the position of the spiral groove 433. The more turns the untwisted yarn is wound, the more the component housing 431 and the spools 562 are powered to rotate. The difference in rotation speed causes the untwisted yarn to be stretched to complete the texturing process. When the component housing 431 and the spools 562 rotate, the untwisted yarn is less likely to unwind, thus making the anti-stiffness effect of the untwisted yarn better.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
