Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile production, and particularly relates to a yarn twisting process and a tensioner. BACKGROUND

[0002] Twisting is an important link in textile production. In the twisting process, one end of the yarn is fixed, and the other end is subjected to torsional force, so that the fibers inside the yarn produce relative displacement to form a twist. The number of twists, i.e. the twist, is one of the key factors that determine the performance of the yarn. Proper twist can increase the strength and wear resistance of the yarn, and improve its appearance and hand feeling. Therefore, the twisting process is crucial to improving the physical and mechanical properties of the yarn and the clothing effect.

[0003] In existing clothing, in order to improve the physical and mechanical properties of the clothing, yarns formed by twisting two silk threads or yarns formed by twisting two twisted silk threads are usually used for textile production. The yarns obtained by the above twisting process have uniform texture, and the clothing obtained by textile production of the yarns is not only more firm, but also has a smooth surface.

[0004] However, the clothing obtained by textile production of the yarns obtained by the existing twisting process has insufficient three-dimensionality due to the uniform texture of the yarns, which affects the visual effect of the clothing. At the same time, the smooth surface of the clothing increases the contact area between the clothing and the skin, which will affect the air permeability of the clothing and the comfort after wearing the clothing. SUMMARY

[0005] The present application provides a yarn twisting process and a tensioner, which can improve the physical and mechanical properties of the yarn while improving the graininess and profile of the surface of the yarn, thereby effectively improving the three-dimensionality and comfort of the clothing obtained by textile production of the yarn.

[0006] In one aspect, the present application provides a yarn twisting process, which adopts the following technical scheme:

[0007] A yarn twisting process, comprising the following steps:

[0008] Twisting thread pay-off;

[0009] Untwisted thread pay-off;

[0010] The untwisted thread is combined with the twisting thread after being tensioned;

[0011] Roller twisting finishing;

[0012] Twist machine twisting.

[0013] By adopting the above technical solutions, the produced yarn can have higher physical and mechanical properties and a higher degree of irregularity in shape, thereby effectively improving the three-dimensionality of clothing produced from the yarn. At the same time, the surface grain and contour of the produced yarn can be improved, reducing the contact area between the clothing produced from the yarn and the human body after wearing, facilitating breathability and heat dissipation, and improving the wearer's comfort.

[0014] On the other hand, this application also provides a tensioner, which adopts the following technical solution:

[0015] A tensioner, used in the twisting process of a yarn as described above, includes a bobbin, a plurality of pressure balls, and a plurality of mating parts that cooperate with the pressure balls;

[0016] The cylinder has an internal cavity, and the two ends of the cylinder along the axial direction have an inlet and an outlet, respectively, both of which communicate with the cavity.

[0017] The fitting component is located in the cavity, and the fitting component has a threading hole for the untwisted thread to pass through and a movable groove for the pressure ball to move; the threading hole communicates with the movable groove, the end of the threading hole away from the movable groove is close to the outlet, and the end of the movable groove away from the threading hole is close to the inlet.

[0018] The pressure ball is located in the movable groove. Under its own gravity, the pressure ball moves toward the direction of the corresponding threading hole, pressing the untwisted thread passing through the corresponding threading hole.

[0019] By adopting the above technical solution, after the untwisted yarn passes through the tensioner, the pressure ball applies a force to the untwisted yarn, so that when the untwisted yarn outside the yarn outlet continues to move, it needs to overcome the resistance between the untwisted yarn, the pressure ball, and the mating parts. This allows the part of the untwisted yarn after the contact point with the pressure ball to be in a tensioned state, which facilitates the subsequent combination and twisting of the untwisted yarn with the twisted yarn. This ensures that the produced yarn has both high physical and mechanical properties and high graininess and outline.

[0020] Optionally, the cylinder is positioned with its axis vertical, the movable groove is bucket-shaped, and the movable groove narrows towards the corresponding wire hole.

[0021] By adopting the above technical solution, the untwisted yarn can easily pass through the tensioner under its own gravity, minimizing the probability of the untwisted yarn coming into contact with other structures during the process of passing through the tensioner. This effectively ensures the tensioning effect of the tensioner on the untwisted yarn and reduces the probability of the untwisted yarn breaking. At the same time, it allows the pressure ball to easily apply a uniform force to the untwisted yarn in the movable groove, thereby effectively improving the reliability of the tensioner in tensioning the untwisted yarn.

[0022] Optionally, there is one mating component, and there are multiple pressure balls with various specifications depending on their mass;

[0023] The cylinder has a detachable cover. After the cover is removed from the cylinder, a material inlet is formed on the cylinder for the pressure ball and the mating component to enter and exit. The material inlet communicates with the space in the cavity on the side of the mating component away from the outlet.

[0024] By adopting the above technical solution, workers can easily select pressure balls of different qualities to apply different forces to different untwisted yarns, thereby allowing different untwisted yarns to be subjected to different degrees of tension, thus meeting the twisting requirements of different untwisted yarns and, consequently, meeting the yarn supply needs of different garments.

[0025] Optionally, the mating parts are multiple, the pressure ball is one and magnetic, and the pressure ball exerts different pressures on the untwisted yarn in the multiple movable grooves;

[0026] It also includes a movable component and a first magnetic component; the movable component is sleeved on the outside of the cylinder, and the movable component can slide in a direction parallel to the axis of the cylinder relative to the cylinder, and can also rotate about the axis of the cylinder; the first magnetic component is disposed on the side of the movable component close to the cylinder, and the first magnetic component is magnetically attracted to the pressure ball;

[0027] The cylinder has a guide groove and multiple guide grooves adapted to the pressure ball on the inner wall of the cavity. The multiple guide grooves correspond one-to-one with the multiple mating parts. The two ends of the guide grooves are respectively connected to the corresponding movable grooves and guide grooves.

[0028] By adopting the above technical solution, the movement of the pressure ball within the cylinder can be controlled by controlling the movement of the movable part relative to the cylinder. This allows the pressure ball to apply different magnitudes of force to the untwisted yarn when it is located in different movable slots. As a result, the tensioning effect of the tensioner on the untwisted yarn can be easily adjusted by the operator without disassembling the tensioner.

[0029] Optionally, one side of the cylinder has a window for observing the location of the pressure ball, the window is connected to the cavity, and the cylinder is provided with a transparent cover plate at the window.

[0030] By adopting the above technical solution, it is possible for staff to easily observe the movement of the pressure ball inside the cylinder, thereby further enabling staff to control the position of the pressure ball inside the cylinder by controlling the movement of the moving parts.

[0031] Optionally, the pressure exerted by the pressure ball on the untwisted yarn in the movable groove near the yarn outlet is greater than the pressure exerted by the pressure ball on the untwisted yarn in the movable groove away from the yarn outlet.

[0032] By adopting the above technical solution, if the tensioner has a stronger tensioning effect on the untwisted thread, the length of the tensioned part of the untwisted thread will be shorter, thereby further reducing the probability of the untwisted thread breaking during the tensioning process of the tensioner.

[0033] Optionally, the mating parts are multiple and have a magnetic shielding effect, the pressure balls are multiple and all have magnetic properties, and the multiple pressure balls have different masses and are located in multiple movable slots respectively;

[0034] It also includes multiple sliding members and multiple second magnetic members; the multiple sliding members correspond one-to-one with multiple mating members, the sliding members are slidably connected to the cylinder, and the sliding members can pass through one side of the corresponding mating members during the sliding process; the multiple second magnetic members correspond one-to-one with the multiple sliding members, the second magnetic members are disposed on the corresponding sliding members, and the second magnetic members are magnetically attracted to the pressure ball.

[0035] By adopting the above technical solution, the position of different pressure balls in the movable groove can be controlled by sliding control of multiple sliding parts, thereby controlling whether the pressure balls apply force to the untwisted yarn. By applying different magnitudes of force to the untwisted yarn with pressure balls of different masses, it is possible for workers to conveniently adjust the tensioning effect of the tensioner on the untwisted yarn without disassembling the tensioner.

[0036] Optionally, the mass of the pressure ball that is closer to the outlet is greater than the mass of the pressure ball that is farther from the outlet.

[0037] By adopting the above technical solution, if the tensioner has a stronger tensioning effect on the untwisted thread, the length of the tensioned part of the untwisted thread will be shorter, thereby further reducing the probability of the untwisted thread breaking during the tensioning process of the tensioner.

[0038] Optionally, it also includes a plurality of lead wire components, which are located in the cavity and on the side of the mating component near the outlet; the lead wire components are provided with lead wire channels for the untwisted wire to pass through, and the lead wire channels are narrowed in the direction of the outlet.

[0039] By adopting the above technical solution, the tensioned untwisted yarn can be guided out of the exit hole, thereby reducing the probability of yarn breakage during the tensioned untwisted yarn's exit process.

[0040] In summary, this application includes at least one of the following beneficial effects:

[0041] 1. It enables the production of yarns that possess both high physical and mechanical properties, as well as a grainy texture and a defined shape, thus meeting a wider range of garment requirements;

[0042] 2. It can give garments made from the produced yarn a higher three-dimensional feel and improve the visual effect of the garments;

[0043] 3. It enables clothing made from the produced yarn to have a higher level of comfort, reduces the contact area between the clothing and the body, and improves the breathability of the clothing;

[0044] 4. It allows workers to easily tension untwisted yarn to different degrees according to different yarn requirements, so that the twisted yarn has the required physical and mechanical properties, texture and shape, and thus the garments made from it have a better three-dimensional feel and comfort.

[0045] 5. It can effectively reduce the probability of untwisted yarn breaking during the tensioning process, effectively improve the reliability of the tensioner in tensioning untwisted yarn, and reduce the difficulty of operating the tensioner. Attached Figure Description

[0055] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0056] Example 1:

[0057] This application discloses a yarn twisting process for producing a yarn that has both high physical and mechanical properties, a high degree of surface texture, and high overall profile. The process includes the following steps:

[0058] S1, release the twisted yarn.

[0059] Take the twisted thread from the spool of the twisted thread. In this embodiment, the twisted thread is preferably a thread formed by twisting two single strands together.

[0060] S2, Untwisted yarn release.

[0061] Untwisted thread is taken from an untwisted spool. In this embodiment, the untwisted thread is preferably a single strand.

[0062] S3. The untwisted yarn is tensioned and then combined with the twisted yarn.

[0063] After the untwisted yarn is released, it is tensioned by a tensioner and then merged with the twisted yarn that is being tensioned directly.

[0064] S4, roller twisting finishing.

[0065] The combined untwisted and twisted yarns are then twisted together by rollers to match the tension of the untwisted yarn with that of the twisted yarn. In this embodiment, a winch-type roller is preferred.

[0066] S5, twisting machine twisting.

[0067] A twisting machine twists together the silk threads that have been twisted by rollers to obtain yarn with the required twist.

[0068] The order of steps S1 and S2 can be reversed or performed simultaneously.

[0069] Reference Figure 1 The above-mentioned yarn twisting process is based on the following twisting equipment:

[0070] The twisting equipment includes a frame 1, several first bobbins 2, several second bobbins 3, several lead-in frames 4, several tensioners 5, several rollers 6, and several twisting machines. The frame 1 serves as the mounting carrier for the other structures; untwisted yarn is wound on the first bobbins 2; twisted yarn is wound on the second bobbins 3; the lead-in frames 4 guide the direction of the untwisted and twisted yarns after unwinding; the tensioners 5 tension the untwisted yarn; the rollers 6 twist and arrange the yarns to match the tension of different yarns; and the twisting machines twist the untwisted and twisted yarns together to form the desired yarn. In this embodiment, since the tensioners 5, rollers 6, and twisting machines are all prior art in the field, they will not be described in detail here, and the twisting machines are omitted from the accompanying drawings.

[0071] The plurality of first bobbins 2, second bobbins 3, thread guides 4, tensioners 5, rollers 6, and twisting machines mounted on the frame 1 can be divided into several twisting units. Each twisting unit can produce a desired yarn, and each twisting unit includes a first bobbin 2, a second bobbin 3, two thread guides 4, a tensioner 5, a roller 6, and a twisting machine. In this embodiment, for ease of subsequent description and illustration, only one twisting unit on the frame 1 is described and illustrated.

[0072] Both the first spool 2 and the second spool 3 are fixedly installed on the frame 1, and both the first spool 2 and the second spool 3 are in a vertical position after being installed on the frame 1.

[0073] Both lead frames 4 are fixedly installed on the top of the frame 1. The two lead frames 4 are located above the first spool 2 and the second spool 3 respectively, and the lead frames 4 have several lead holes for the wires to pass through.

[0074] Taking the first spool 2 as an example, after the untwisted wire on the first spool 2 is released, it is first led upwards to approach the lead wire frame 4, and then passed through several lead wire holes on the lead wire frame 4 one after another, so that the untwisted wire travels along the lead wire frame 4 for a certain distance before being led downwards.

[0075] Both the tensioner 5 and the roller 6 are mounted on one side of the frame 1 and located below the lead wire frame 4, with the roller 6 located below the tensioner 5. After being led down by the lead wire frame 4, the untwisted wire first contacts the tensioner 5 and then is twisted and shaped by the roller 6. The tensioner 5 ensures the untwisted wire enters the roller 6 in a taut state. In this embodiment, it is preferable that the untwisted wire after being led down by the lead wire frame 4 is led downwards in a vertical direction, and the portion of the untwisted wire between the lead wire frame 4 and the roller 6 remains vertical. Since the tensioner 5 is prior art, it is not further limited here.

[0076] A lead rod 11 extends outward from one side of the frame 1. The end of the lead rod 11 away from the frame 1 also has a lead hole for the wire to pass through. The lead rod 11 is located between the tensioner 5 and the roller 6, and the untwisted part of the wire between the tensioner 5 and the roller 6 can pass through the lead hole on the lead rod 11.

[0077] The lead-out trajectory of the twisted wire on the second spool 3 after being released is similar to the lead-out trajectory of the untwisted wire on the first spool 2 after being released.

[0078] After the twisted thread is guided by the lead wire holder 4, it is led downwards. On the frame 1, near the roller 6, there is a tensioning member 12 for tensioning the twisted thread upon contact. The tensioning member 12 is located above the lead wire rod 11. After the twisted thread contacts the tensioning member 12, it is manually tensioned by the operator, allowing it to pass through the lead wire hole on the lead wire rod 11 and enter the roller 6 together with the untwisted thread. In this embodiment, the tensioning member 12 is preferably a smooth round rod with a horizontal axis; tensioning is achieved by applying force after the twisted thread is wound around the tensioning member 12.

[0079] To improve the reliability of tension matching between untwisted and twisted yarns after twisting by roller 6, the surface of roller 6 that contacts the yarn has a large coefficient of friction with the yarn, reducing the probability of yarn slippage, thus ensuring the twisting effect of the untwisted and twisted yarns and improving the quality of the produced yarn.

[0080] The implementation principle of a yarn twisting process in this application embodiment is as follows:

[0081] Yarn formed by twisting two strands of yarn with different shapes, untwisted yarn and twisted yarn, has the higher physical and mechanical properties of twisted yarn. At the same time, its irregular surface gives it a higher graininess and contour, resulting in better three-dimensionality and comfort in the final textile garments.

[0082] Example 2:

[0083] This application discloses a tensioner, which is applied in a yarn twisting process in Embodiment 1, for tensioning untwisted yarn.

[0084] Reference Figure 2 and Figure 3The tensioner 5 includes a cylinder 51, several housings 55, several mating parts 52, several pressure balls 54, and several lead wires 53.

[0085] The cylinder 51 has a cylindrical structure, and its interior has a cylindrical cavity 511, with the axis of the cavity 511 coinciding with the axis of the cylinder 51. In this embodiment, after the tensioner 5 is installed on the frame 1, the cylinder 51 is in a vertical position.

[0086] The two ends of the cylinder 51 along the axial direction have an inlet 512 and an outlet 513, respectively. The inlet 512 is located above the outlet 513. Both the inlet 512 and the outlet 513 are connected to the cavity 511 and can allow untwisted yarn to pass through the tensioner 5 in the vertical direction in sequence through the inlet 512, the cavity 511 and the outlet 513.

[0087] Both the mating component 52 and the lead wire component 53 are cylindrical in shape. Both are located within the cavity 511, with the mating component 52 positioned above the lead wire component 53. In this embodiment, the tensioner 5 preferably includes one mating component 52 and one lead wire component 53. Both are located within the cavity 511 near the outlet 513, with the mating component 52 positioned above the lead wire component 53.

[0088] Both the mating component 52 and the lead wire 53 can be detachably connected to the housing 55, and both the mating component 52 and the lead wire 53 are installed in the cavity 511 in the state after being connected to the housing 55. Therefore, in this embodiment, the tensioner 5 preferably includes two housings 55.

[0089] The housing 55 is generally cylindrical in shape to fit the cavity 511. The interior of the housing 55 has mounting grooves 551 that fit the mating parts 52 and the lead wires 53. An opening is formed at one end of the mounting groove 551 along the axial direction of the housing 55 to allow the mating parts 52 and the lead wires 53 to enter. In this embodiment, it is preferred that the mating parts 52 and the lead wires 53 are detachably connected to the housing 55 via an interference fit. Preferably, the housing 55 is made of plastic and has a certain degree of elasticity, while the mating parts 52 and the lead wires 53 are made of ceramic material and have smooth surfaces to reduce the probability of frictional damage when the untwisted wire comes into contact with the mating parts 52 and the lead wires 53.

[0090] After the lead wire 53 mounted on the housing 55 is installed in the cavity 511, the axis of the lead wire 53 coincides with the axis of the cavity 511. The lead wire 53 has a lead wire channel 531 for untwisted wire to pass through. The lead wire channel 531 includes an inlet 532 and an outlet 533. The outlet 533 is located on the side of the inlet 532 near the outlet 513. The two ends of the inlet 532 are respectively connected to the cavity 511 and the outlet 533, and the two ends of the outlet 533 are respectively connected to the inlet 532 and the outlet 513.

[0091] The inlet 532 has a funnel-shaped structure, and the outlet 533 has a round hole shape. The axes of the inlet 532, the outlet 533, and the lead wire 53 all coincide. The inlet 532 narrows towards the outlet 533, and the radial dimension of the outlet 533 matches the radial dimension of the wire outlet 513, so that the end of the untwisted wire can enter the outlet 533 from the inlet 532 and then pass through.

[0092] At this time, the part of the untwisted wire near the outlet 513 will be in contact with the tensioner 5, which will be concentrated on the lead wire 53, thereby reducing the probability of the untwisted wire breaking due to excessive damage from contact with the tensioner 5 during the tensioning process.

[0093] After the mating component 52, mounted on the housing 55, is installed in the cavity 511, the axis of the mating component 52 coincides with the axis of the cavity 511. The mating component 52 has a movable groove 521 for the pressure ball 54 to move and a threading hole 522 for the untwisted thread to pass through, and the threading hole 522 is located on the side of the movable groove 521 near the outlet 513. At this time, the bottom of the housing 55 corresponding to the mating component 52 contacts and abuts against the top of the housing 55 corresponding to the lead wire component 53, so the two ends of the movable groove 521 communicate with the cavity 511 and the threading hole 522 respectively, and the two ends of the threading hole 522 communicate with the movable groove 521 and the lead wire channel 531 respectively.

[0094] The movable groove 521 has a bucket-shaped structure, and the threading hole 522 is a round hole. The axes of the movable groove 521, the threading hole 522, and the mating part 52 all coincide. The movable groove 521 narrows towards the threading hole 522, and the radial dimension of the threading hole 522 matches the radial dimension of the outlet 533 of the lead wire channel 531, so that the untwisted wire passing through the mating part 52 can pass through the lead wire part 53.

[0095] The pressure ball 54 has a spherical structure, and its radial dimension is larger than that of the wire hole 522. After the mating part 52 is installed, the pressure ball 54 is placed in the cavity 511 and is located in the movable groove 521 under its own gravity. In this embodiment, the pressure ball 54 is preferably made of metal and has a smooth surface.

[0096] At this time, when the untwisted thread passes through the mating part 52, the pressure ball 54 will contact the part of the untwisted thread near the position where the movable groove 521 communicates with the threading hole 522 under its own gravity, and clamp this part of the untwisted thread between the pressure ball 54 and the mating part 52, thereby making the part of the untwisted thread from the pressure ball 54 to the roller 6 subject to a tensioning effect.

[0097] The fitting 52 is equipped with various pressure balls 54 of different qualities. Different pressure balls 54 can apply different magnitudes of force to the untwisted yarn, so that the staff can easily determine the appropriate pressure ball 54 to use based on the material, thickness and other variables of the untwisted yarn, thereby ensuring that the untwisted yarn is subjected to a suitable tension effect.

[0098] Furthermore, to facilitate the replacement of the pressure ball 54, mating part 52, and lead wire 53, a cover 514 can be detached from the cylinder 51. After the cover 514 is removed from the cylinder 51, a feed port 515 is formed, allowing the pressure ball 54, mating part 52, and lead wire 53 to enter and exit. In this embodiment, the cover 514 is preferably located on the cylinder 51 near the inlet 512, and the structure of the cover 514 includes the inlet 512. At this time, the radial dimension of the feed port 515 is equal to the radial dimension of the cavity 511; and preferably, the cover 514 is detachably connected to the cylinder 51 by a threaded connection.

[0099] The implementation principle of a tensioner according to an embodiment of this application is as follows:

[0100] When the untwisted thread is tensioned by the tensioner 5, it will pass through the inlet 512, cavity 511, movable groove 521, threading hole 522, lead-in channel 531 and outlet 513 in sequence. The untwisted thread will come into contact with the pressure ball 54 and be subjected to the force applied by the pressure ball 54 around the point where the movable groove 521 and the threading hole 522 communicate, so that the part of the untwisted thread between the pressure ball 54 and the roller 6 is tensioned, which makes it easier for the untwisted thread to be twisted with the twisted thread later.

[0101] When it is necessary to replace the mating part 52, the lead wire 53, and the pressure ball 54, remove the cover 514, and then take out the mating part 52, the lead wire 53, and the pressure ball 54 that need to be replaced from the feed port 515. Then put the mating part 52, the lead wire 53, and the pressure ball 54 into the feed port 515.

[0102] Example 3:

[0103] Reference Figure 2 and Figure 4 The difference between this embodiment and embodiment 2 is that the housing 55, the mating part 52, and the cylinder 51 are included, and the tensioner 5 also includes a movable part 56, a first magnetic suction part 57, and a cover plate 7.

[0104] ReferenceFigure 4 and Figure 5 In this embodiment, there are multiple mating parts 52, and the degree of narrowing of the movable groove 521 of each mating part 52 is different. In this embodiment, the tensioner 5 preferably includes three mating parts 52, and correspondingly, the tensioner 5 preferably includes four housings 55 (where the three housings 55 are used in conjunction with the three mating parts 52 respectively).

[0105] After multiple mating parts 52 are installed in the cavity 511 with the housing 55 mounted on it, the degree of narrowing of the movable grooves 521 of the multiple mating parts 52 gradually decreases towards the outlet 513. That is, the inclination of the groove wall of the movable groove 521 relative to the radial direction of the mating parts 52 gradually decreases, so that the pressure ball 54 exerts a greater force on the untwisted wire in the movable groove 521 closer to the outlet 513.

[0106] Reference Figure 5 and Figure 6 Inside the cylinder 51, a guide groove 516 adapted to the pressure ball 54 is formed on one side of the cavity 511. The guide groove 516 communicates with the cavity 511, and the housing 55, which mates with the fitting part 52, also has a ball opening 552 for the pressure ball 54 to enter and exit the mounting groove 551. In this embodiment, it is preferable that the opening trajectory of the guide groove 516 is parallel to the axial direction of the cylinder 51.

[0107] After the mating part 52 is installed into the mounting groove 551 of the housing 55, the mounting groove 551 still has some space on the side of the movable groove 521 away from the corresponding wire hole 522, and the ball joint 552 will communicate with part of the space in the mounting groove 551. After multiple mating parts 52 installed with the housing 55 are installed in the cavity 511, the ball joints 552 on multiple housings 55 can communicate with the guide groove 516.

[0108] Furthermore, to facilitate the connection between the ball joint 552 on the corresponding housing 55 and the guide groove 516 after the mating part 52 is installed, it is preferable that the outer side of the housing 55 has several positioning strips 553, and the inner wall of the cylinder 51 has several positioning grooves 519 that are adapted to the positioning strips 553. In this embodiment, it is preferable that the housing 55 has two positioning strips 553, and the two positioning strips 553 are located at both ends of the housing 55 in the same radial direction.

[0109] The length direction of the positioning strip 553 is parallel to the axial direction of the housing 55, and the opening trajectory of the positioning strip 553 on the cylinder 51 is parallel to the axial direction of the cylinder 51. After the housing 55 is installed in the cavity 511 with the positioning strip 553 and the positioning groove 519 in cooperation, the ball opening 552 on the housing 55 will communicate with the guide groove 516.

[0110] Furthermore, to facilitate the entry of the pressure ball 54 from the guide groove 516 through the ball opening 552 into the movable groove 521, the cylinder 51 is provided with several guide grooves 517 on the inner wall of the cavity 511, and the several guide grooves 517 correspond one-to-one with the several movable grooves 521. Therefore, in this embodiment, it is preferable that the cylinder 51 is provided with a total of three guide grooves 517.

[0111] All three guide grooves 517 are located on the same side of the guide groove 516, and after the three mating parts 52 are installed in the cavity 511, the two ends of the guide groove 517 communicate with the corresponding ball opening 552 and the guide groove 516, respectively. In this embodiment, the guide groove 517 is preferably a wedge-shaped groove, and the guide groove 517 is adapted to the pressure ball 54. The groove wall of the guide groove 517 can guide the pressure ball 54 from the guide groove 516 through the ball opening 552 into the corresponding movable groove 521.

[0112] The movable component 56 is an overall ring structure. The movable component 56 is sleeved on the outside of the cylinder 51, and the axis of the movable component 56 coincides with the axis of the cylinder 51. The movable component 56 is movably connected to the cylinder 51, and can slide relative to the cylinder 51 along the axis of the cylinder 51, and can also rotate relative to the cylinder 51 about the axis of the cylinder 51.

[0113] Furthermore, the movable member 56 is restricted during its sliding relative to the cylinder 51 along the axial direction of the cylinder 51, and the outer side of the cylinder 51 has structures for limiting the movable member 56 at both ends near the axial direction of the cylinder 51.

[0114] When the movable part 56 moves to its limit position in the direction of approaching the inlet 512, the movable part 56 is fitted outside the mating part 52 closest to the inlet 512; when the movable part 56 moves to its limit position in the direction of approaching the outlet 513, the movable part 56 is fitted outside the lead wire part 53.

[0115] The first magnetic attractor 57 is fixedly installed on the inside of the movable part 56. The pressure ball 54 itself is also magnetic, and the first magnetic attractor 57 and the pressure ball 54 are magnetically attracted to each other.

[0116] At this time, controlling the movement of the movable part 56 relative to the cylinder 51 can control the movement of the first magnetic suction part 57 relative to the cylinder 51. The movement of the first magnetic suction part 57 can drive the pressure ball 54 to move along it through magnetic attraction. This allows the operator to easily control the movement of the movable part 56 to drive the pressure ball 54 to leave the movable slot 521 through the ball opening 552 and move along the guide slot 516 and enter the required movable slot 521 through the corresponding ball opening 552, thus completing the position change of the pressure ball 54 in the three movable slots 521.

[0117] When the movable part 56 moves to its limit position towards the outlet 513 under its own gravity, the magnetic attraction of the first magnetic attractor 57 to the pressure ball 54 located in any movable slot 521 is small, and the influence of the force exerted by the pressure ball 54 on the untwisted wire is negligible.

[0118] Furthermore, to facilitate the operation of staff by controlling the movement of the pressure ball 54 through the movable part 56 and to know the location of the pressure ball 54, a window 518 is provided on one side of the cylinder 51, and the window 518 connects the cavity 511 with the outer space of the cylinder 51.

[0119] The preferred window 518 has a rectangular structure and is located on the side of the cylinder 51 away from the guide groove 516. The preferred window 518 is located between the two limiting structures on the outside of the cylinder 51.

[0120] A transparent cover plate 7 is fixedly installed on the cylinder 51 at the window 518. The outer end face of the cover plate 7 is flush with the outer end face of the cylinder 51, and the inner end face of the cover plate 7 is flush with the inner wall of the cavity 511. In this embodiment, the cover plate 7 is preferably made of glass, so that the staff can observe the situation in the three movable slots 521 through the cover plate 7.

[0121] Furthermore, preferably, the housing 55 is made of transparent plastic material, so that the staff can observe the situation in the three movable slots 521 through the cover plate 7.

[0122] The implementation principle of a tensioner according to an embodiment of this application is as follows:

[0123] When it is necessary to adjust the tensioning effect of the tensioner 5 on the untwisted yarn according to factors such as the material of the untwisted yarn, the operator observes the position of the pressure ball 54 in the cavity 511 through the cover plate 7, and at the same time manually controls the movable part 56 to move relative to the cylinder 51. Through the magnetic attraction between the first magnetic suction part 57 and the pressure ball 54, the pressure ball 54 is driven to enter and exit the ball port 552 and move along the guide groove 516, so that the pressure ball 54 can enter the appropriate movable groove 521 to contact the untwisted yarn, apply an appropriate force to the untwisted yarn, and make the untwisted yarn receive the appropriate tensioning effect of the tensioner 5.

[0124] Example 4:

[0125] Reference Figure 4 and Figure 7 The difference between this embodiment and embodiment 3 lies in the mating part 52 and the pressure ball 54.

[0126] Reference Figure 6 and Figure 8The cylinder 51 does not have a positioning groove 519, a guide groove 516, or a guide groove 517. The shell 55 does not have a positioning strip 553 and does not have a ball opening 552. Furthermore, no movable part 56 is installed outside the cylinder 51. The tensioner 5 also includes several sliding parts 58 and several second magnetic parts 59.

[0127] Reference Figure 7 and Figure 8 The three mating parts 52 have the same structure, and each movable groove 521 has a pressure ball 54. Therefore, in this embodiment, the tensioner 5 includes a total of three pressure balls 54.

[0128] The three pressure balls 54 have different masses, and are located in the three movable slots 521 in order of increasing mass towards the outlet 513. In this embodiment, it is preferable that the three pressure balls 54 are made of the same material, and the difference in mass is achieved by the difference in volume.

[0129] A number of sliding elements 58 correspond one-to-one with a number of mating elements 52. Therefore, in this embodiment, the tensioner 5 preferably includes three sliding elements 58.

[0130] The slider 58 is installed on the outside of the cylinder 51, and the slider 58 is slidably connected to the cylinder 51 along the axial direction of the cylinder 51. In this embodiment, the slider 58 is preferably located on the side of the cylinder 51 away from the window 518.

[0131] The sliding member 58 is restricted during its sliding relative to the cylinder 51. When the sliding member 58 slides to its limit position in the direction of approaching the inlet 512, the sliding member 58 will be located on one side of the top of the housing 55 equipped with the corresponding mating member 52. When the sliding member 58 slides to its limit position in the direction of approaching the outlet 513, the sliding member 58 will be located on the side of the corresponding mating member 52 near the wire hole 522. This ensures that the sliding member 58 remains on one side of the mating member 52 installed in the housing 55 during its sliding process.

[0132] Several second magnetic suction elements 59 correspond one-to-one with several sliding elements 58. The second magnetic suction elements 59 are fixedly installed on the side of the corresponding sliding element 58 near the cylinder 51, and there is a magnetic attraction between the second magnetic suction elements 59 and the pressure ball 54. When the sliding element 58 slides to its limit position towards the inlet 512, the pressure ball 54 in the corresponding movable groove 521 will be subjected to the magnetic attraction force and move towards the second magnetic suction element 59 until it abuts against and holds against the groove wall of the mounting groove 551. At this time, the pressure ball 54 has no contact with the untwisted wire passing through the corresponding mating part 52. When the sliding element 58 slides to its limit position towards the outlet 513, the magnetic attraction force of the second magnetic suction element 59 on the pressure ball 54 in the corresponding movable groove 521 is weakened, and the influence of the second magnetic suction element 59 on the pressure ball 54 in the corresponding movable groove 521 is negligible. The pressure ball 54 can normally apply force to the untwisted wire passing through the corresponding mating part 52. In this embodiment, the preferred fitting 52 is made of a ceramic material with a certain magnetic shielding effect.

[0133] The implementation principle of a tensioner according to an embodiment of this application is as follows:

[0134] When it is necessary to adjust the tensioning effect of the tensioner 5 on the untwisted yarn according to factors such as the material of the untwisted yarn, the operator observes the position of the pressure ball 54 in the cavity 511 through the cover plate 7, and then controls the sliding of several sliding parts 58 so that the sliding part 58 corresponding to the pressure ball 54 to be used slides to the limit position in the direction closer to the outlet 513, and the other sliding parts 58 slide to the limit position in the direction closer to the inlet 512.

[0135] At this time, the pressure ball 54 used can contact the untwisted thread passing through the tensioner 5 and apply a suitable force so that the untwisted thread is subjected to a suitable tensioning effect from the tensioner 5; while the other pressure balls 54 are all attracted to the inner wall of the corresponding mounting groove 551 by the magnetic attraction of the corresponding second magnetic attractor 59, and remain in no contact with the untwisted thread.

[0136] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
