Description

Technical Field

[0001] This invention relates to the field of vortex spinning technology, specifically an air-jet vortex spinning twister. Background Technology

[0002] Vortex spinning utilizes a high-speed rotating air vortex to twist the yarn. After drafting, the fiber sliver exits from the front roller nip and is immediately fed into a specially designed vortex spinning chamber. Inside the chamber, compressed air introduced through tangential nozzles creates a stable and intense rotating vortex field. Under the action of the vortex, the ends of the fiber bundle rapidly expand, separate, and rotate at high speed around their tips, thus twisting and wrapping the fiber ends to form a uniquely structured yarn. This technology boasts extremely high spinning speeds and a very short process, completing the process from fiber to yarn in one step. The produced yarn has a fluffy structure, minimal hairiness, vibrant colors, and is abrasion-resistant and pill-resistant, but it typically has a stiffer hand feel, making it particularly suitable for knitted sportswear fabrics, home textiles, and products requiring a smooth finish.

[0003] Existing jet vortex spinning twisters have the following shortcomings: 1. Existing vortex spinning machines apply wax to the yarn before winding to lubricate it and reduce friction during subsequent weaving. Typically, the equipment is equipped with a fixed, plate-shaped wax block. The yarn continuously slides over its surface during winding, thus evenly adhering to the wax. However, to achieve a smooth winding of the yarn on the bobbin, the winding device is equipped with a precision yarn guide, which drives the yarn to move back and forth at high speed. When the yarn slides laterally over the surface of the stationary wax block, significant lateral friction is generated between the two. This friction force forces the already twisted and set yarn to roll or rotate axially. This unintended twisting can damage the precise twist structure inside the yarn, causing it to become loose in parts or throughout, resulting in a decrease in strength, or even minor defects, directly affecting the quality and stability of the final yarn.

[0004] 2. In the waxing process of existing vortex spinning machines, the wax block is rigidly fixed to the frame as a passive component. Its installation position and posture cannot be adjusted during yarn winding. This completely static setting means that when the yarn guide drives the yarn to move laterally at high speed, scraping against the surface of the wax block at a certain angle and pressure, the wax block itself cannot make any adaptive rotational movement to respond to or buffer this lateral friction force. Therefore, all the frictional resistance borne by the yarn is directly converted into torsional torque, which acts in the opposite direction on the yarn body. This causes the yarn to continuously bear destructive reverse torque during the most vulnerable setting stage after twisting. The loss of twist and the loosening of the structure then become unavoidable process defects. Summary of the Invention

[0005] The purpose of this invention is to provide an air jet vortex spinning twister to solve the problems mentioned in the background art.

[0006] To achieve this objective, the present invention adopts the following technical solution: A jet-jet vortex spinning twister is provided, comprising a frame, a housing, a vortex twisting chamber, and a control panel. The housing is fixedly mounted on the frame, the vortex twisting chamber is mounted on the housing, and the control panel is mounted on the side of the housing. The frame contains a yarn guiding assembly for evenly distributing the yarn. The inner top surface of the frame has a waxing mechanism, which includes a mounting plate, suspension rods, a fixing frame, a sliding assembly, a connecting rod, a linkage assembly, a reversing assembly, a positioning shaft, a first auxiliary gear, a hollow shaft, a second auxiliary gear, a placement cylinder, and a wax block. Two mounting plates are provided, both fixedly mounted on the inner top surface of the frame. The suspension rods are fixedly mounted at the bottom of the mounting plates, and the fixing frame is mounted at the bottom of the two suspension rods. The sliding assembly is located inside the fixed frame. The connecting rod is located between the moving ends of the sliding assembly and the yarn guiding assembly. The linkage assembly and the reversing assembly are both located on the sliding assembly. The positioning shaft is fixedly located on the sliding assembly. The first auxiliary gear is rotatably located at the top of the positioning shaft. The hollow shaft is rotatably located on the sliding assembly. The second auxiliary gear is fixedly located on the outside of the hollow shaft. The first auxiliary gear and the second auxiliary gear mesh with each other.

The machine housing is equipped with a guide assembly for positioning the thick yarn. The machine housing is also equipped with a transmission assembly and a feeding assembly for conveying the thick yarn. The inside of the frame is equipped with a winding assembly for winding the yarn.

[0007] Furthermore: the sliding assembly includes a limiting rod, a movable seat, and a through hole. The limiting rod is fixed inside the fixed frame. The through hole is opened through the movable seat along the length direction. The limiting rod passes through the through hole and slides with it. The positioning shaft is fixed to the movable seat. The hollow shaft is rotatably engaged with the movable seat. The movable seat has a yarn-threading hole coaxial with the hollow shaft.

[0008] Furthermore: the linkage assembly includes a rack, a gear shaft, and a main gear.

[0009] Furthermore: The reversing assembly includes a limit frame, a slide block, an idler wheel, and limit heads. The limit frame is fixedly mounted on the moving seat. The limit frame is arc-shaped and concentrically positioned with the main gear. The slide block is slidably mounted inside the limit frame. The idler wheel is rotatably mounted on the top of the slide block and meshes with the main gear. When the moving seat moves to the left, the idler wheel meshes with the first set of gears. When the moving seat moves to the right, the idler wheel meshes with the second set of gears. There are two limit heads, which are respectively connected through the two ends of the limit frame. The end of the limit head that is inserted into the limit frame is equipped with a rubber head.

[0010] Furthermore: the yarn guiding assembly includes an electric guide rail, an electric slider, a fixed plate, a guide seat, and a guide hole. The electric guide rail is fixed inside the frame, the electric slider is slidably disposed on the outside of the electric guide rail, the fixed plate is fixed on the top of the electric slider, the guide seat is fixed on the top of the fixed plate, and the guide hole is opened through the side of the guide seat. The two ends of the connecting rod are fixed to the moving seat and the electric slider, respectively.

[0011] Furthermore: the guide assembly includes a fixed plate, a fixed frame, a bushing, a support shaft, and a roller. There are two fixed plates, both of which are fixed to the top of the machine housing. The fixed frame is fixed to the fixed plate, the bushing is fixed to the side of the fixed frame, the support shaft is rotatably located between the two bushings, and the roller is fixed to the outside of the support shaft.

[0012] Furthermore: Two fixing rods are fixedly installed on the inner side of the housing, and guide cylinders are fixedly installed on the sides of the two fixing rods. The longitudinal section of the guide cylinder is a tapered shape that is narrow at the bottom and wide at the top, and the bottom end of the guide cylinder extends to the feed inlet of the feeding assembly.

[0013] Furthermore: the transmission assembly includes a synchronous pulley, a synchronous belt, a limiting roller, and a drive motor. There are multiple synchronous pulleys, all of which are rotatably located inside the machine housing. The synchronous belt is sleeved on the outside of the multiple synchronous pulleys. The limiting roller is located at the corner of the synchronous belt and is in contact with the synchronous belt. The drive motor is fixed inside the machine housing, and the output end of the drive motor is connected to the last synchronous pulley.

[0014] Furthermore: the feeding assembly includes driven gears, a first fixed shaft, a second fixed shaft, a driving gear, comb teeth, and a feeding roller. There are multiple driven gears, which are equally spaced and rotatably connected to the inner wall of the housing. The first fixed shaft is fixed on each driven gear, and the second fixed shaft is fixed on each synchronous pulley not connected to the drive motor. The driving gear is sleeved on the outside of each second fixed shaft and meshes with the corresponding driven gear. The feeding roller is fixed at the ends of the first and second fixed shafts. The comb teeth are fixed on the outside of the lowest feeding roller and are distributed circumferentially around the circumference of the feeding roller.

[0015] Furthermore: the take-up assembly includes a fixed base, a servo motor, a first connecting shaft, a limiting groove, a slot, a spring, a slide rod, a second connecting shaft, a docking rod, a take-up roller, and a docking groove. The fixed base is fixedly installed inside the frame. The servo motor is installed at one end of the fixed base. The first connecting shaft is rotatably installed at the other end of the fixed base. The slot is opened at the end of the first connecting shaft. The limiting groove is opened inside the slot. The spring is installed inside the slot. The slide rod is slidably installed inside the slot and the limiting groove. The two ends of the spring are fixed to the slot and the slide rod, respectively. The second connecting shaft is installed at the output end of the servo motor. The docking rods are fixed at the opposite ends of the slide rod and the second connecting shaft, respectively. The take-up roller is installed between the two docking rods. The docking grooves are opened at both ends of the take-up roller and are adapted to the docking rods.

[0016] The beneficial effects of this invention are: 1. This invention places the wax block inside a rotatable placement cylinder and uses the reciprocating motion of the moving seat to drive the main gear and rack to mesh and rotate. Then, through the sliding reversal of the idler wheel in the limiting frame, the reciprocating motion is transformed into a continuous unidirectional rotation that drives the second auxiliary gear and the placement cylinder. This changes the traditional fixed state of the wax block, allowing it to actively adapt to the lateral movement of the yarn, effectively offsetting the lateral frictional resistance between the yarn and the surface of the wax block, thereby avoiding the problem of reverse twisting of the yarn caused by friction.

[0017] 2. In this invention, the wax block rotates in the same direction as the yarn in lateral movement, which improves the relative motion and frictional torque between the two. When the yarn passes through the threading hole and contacts the rotating wax block for waxing, it no longer bears the destructive reverse twisting torque imposed by the stationary wax block. This protects the twist structure formed after the yarn leaves the vortex twisting chamber, effectively preventing the yarn from becoming loose, losing strength, and developing minor defects due to the waxing process, and improving the mechanical properties and quality stability of the final yarn.

[0018] 3. The feeding assembly of the present invention drives all the second fixed shafts and the driving gear to rotate synchronously via a drive motor, synchronous pulley and synchronous belt. The driving gear then meshes with and drives each driven gear, causing all the feeding rollers to rotate precisely and synchronously in opposite directions, forming a continuous and uniformly gripping conveying channel. The comb teeth distributed circumferentially on the lowest feeding roller can continuously loosen and comb the fiber sliver during the conveying process, ensuring that the fiber sliver can be stably fed into the vortex twisting chamber in a constant and straight state, avoiding accidental fiber stretching, accumulation or misalignment, and providing a uniform and high-quality fiber flow for the front-end high-speed twisting process, ensuring the uniformity of the yarn from the source.

[0019] 4. The winding assembly of this invention is driven by a servo motor, enabling precise control of the winding roller speed and ensuring a constant winding linear speed. The elastic buffer structure formed by the spring, slide bar, and slot at the end of the first connecting shaft provides the connecting rod with a certain axial floating margin when transmitting power. This automatically adapts to the slight axial displacement of the winding roller caused by the increase in the package diameter, buffering possible instantaneous tension fluctuations and preventing yarn damage due to rigid tension. Simultaneously, the cooperation between the connecting rod and the connecting slot facilitates the loading and unloading of the winding roller, improving the efficiency of the roll changing operation.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

[0032] Example 1: The present invention provides a technical solution, such as... Figures 1-8 As shown, a jet-jet vortex spinning twister includes a frame 1, a housing 2, a vortex twisting chamber 3, and a control panel 4. The housing 2 is fixedly mounted on the frame 1, the vortex twisting chamber 3 is mounted on the housing 2, and the control panel 4 is mounted on the side of the housing 2. The interior of the frame 1 is equipped with a yarn guiding assembly for evenly distributing the yarn. The inner top surface of the frame 1 is equipped with a waxing mechanism, which includes a mounting plate 10, a suspension rod 11, a fixing frame 12, a sliding assembly, a connecting rod 14, a linkage assembly, a reversing assembly, a positioning shaft 17, a first auxiliary gear 18, a hollow shaft 19, and a second auxiliary gear 2. 0. The mounting plate 10 consists of two parts: a placement cylinder 21 and a wax block 22. Both mounting plates 10 are fixed to the inner top surface of the frame 1. The suspension rod 11 is fixed to the bottom of the mounting plate 10. The fixing frame 12 is installed at the bottom of the two suspension rods 11. The sliding assembly is located inside the fixing frame 12. The connecting rod 14 is located between the moving ends of the sliding assembly and the yarn guiding assembly. The linkage assembly and the reversing assembly are both located on the sliding assembly. The positioning shaft 17 is fixed to the sliding assembly. The first auxiliary gear 18 is rotatably located at the top of the positioning shaft 17. The hollow shaft 19 is rotatably located on the sliding assembly. The second auxiliary gear 20 is fixedly mounted on the outside of the hollow shaft 19. The first auxiliary gear 18 meshes with the second auxiliary gear 20. The placement cylinder 21 is coaxially fixed on the top surface of the second auxiliary gear 20. The wax block 22 is placed inside the placement cylinder 21. The housing 2 is equipped with a guide assembly for positioning the thick yarn. The housing 2 is also equipped with a transmission assembly and a feeding assembly for conveying the thick yarn. The frame 1 is equipped with a winding assembly for winding the yarn. By integrating functional units such as the vortex twisting chamber 3, the waxing mechanism, the yarn guiding assembly, and the winding assembly into the same frame 1, the wax... The wax block 22 is placed inside the rotatable placement cylinder 21. Through the cooperation of sliding, linkage and reversing components, it is ensured that the wax block 22 always rotates in a single direction during the lateral movement of the yarn. The wax block 22 has been changed from the traditional fixed type to an active rotating type. Its rotation power comes directly from the lateral movement of the yarn. The structure is ingenious and does not require additional drive. It provides a foundation for solving the problem of yarn twist damage during waxing. It realizes integrated and automated production from fiber to finished yarn package. The processes are closely connected and the spatial layout is compact, which significantly improves the equipment integration and production efficiency.

[0033] like Figures 1-3As shown, the sliding assembly includes a limiting rod 131, a movable seat 132, and a through hole 133. The limiting rod 131 is fixedly disposed inside the fixed frame 12. The through hole 133 is opened through the movable seat 132 along its length. The limiting rod 131 passes through the through hole 133 and slides with it. The positioning shaft 17 is fixed to the movable seat 132. The hollow shaft 19 is rotatably engaged with the movable seat 132. The movable seat 132 has a thread hole coaxial with the hollow shaft 19. The movable seat 132 passes through the internal through hole 133. The limit rod 131 of the fixed frame 12 is fitted with the limit rod 133. The limit rod 131 guides and supports the movable seat 132, so that it can only slide horizontally in a fixed direction. The yarn through hole on the movable seat 132 allows the yarn to pass through. The positioning shaft 17 and the hollow shaft 19 are used to install the gear and place the cylinder 21, respectively. The sliding fit between the limit rod 131 and the through hole 133 ensures the linear accuracy and stability of the reciprocating motion of the movable seat 132, which provides a guarantee for the stability of the subsequent gear transmission. At the same time, its structure is simple and has good rigidity.

[0034] like Figures 1-3 As shown, the linkage assembly includes a rack 151, a gear shaft 152, and a main gear 153. The rack 151 is fixedly mounted on the inner side of the fixed frame 12, the gear shaft 152 is rotatably mounted on the movable seat 132, and the main gear 153 is fixedly mounted on the top of the gear shaft 152 and meshes with the rack 151. The rack 151, which is fixedly mounted on the inner side of the fixed frame 12, meshes with the main gear 153, which is rotatably mounted on the movable seat 132. When the movable seat 132 is driven to perform horizontal reciprocating motion, the main gear 153 generates alternating forward and reverse rotational motion due to its meshing relationship with the stationary rack 151. This converts the kinetic energy of the lateral movement of the guide yarn into mechanical energy to drive the gear to rotate, realizing the direct utilization of energy and the conversion of motion form. This provides the initial power source for driving the wax block 22 to rotate, resulting in efficient energy utilization.

[0035] like Figures 1-4As shown, the reversing assembly includes a limiting frame 161, a slide block 162, an idler wheel 163, and limiting heads 164. The limiting frame 161 is fixedly mounted on the movable seat 132. The limiting frame 161 is arc-shaped and concentrically arranged with the main gear 153. The slide block 162 is slidably disposed inside the limiting frame 161. The idler wheel 163 is rotatably disposed at the top of the slide block 162 and meshes with the main gear 153. When the movable seat 132 moves to the left, the idler wheel 163 meshes with the first auxiliary gear 18. When the movable seat 132 moves to the right, the idler wheel 163 meshes with the second auxiliary gear 20. Two limiting heads 164 are provided, which are respectively connected through the two ends of the limiting frame 161. The end of the limiting head 164 that inserts into the limiting frame 161 has a rubber head. The slider 92 drives the moving seat 132 to move back and forth via the connecting rod 14, and the main gear 153 rotates back and forth accordingly. When the moving seat 132 moves to the right, the slide 162 slides to the left end within the arc-shaped limiting frame 161, so that the idler wheel 163 meshes with the second auxiliary gear 20. When it moves to the left, the slide 162 slides to the right end, so that the idler wheel 163 meshes with the first auxiliary gear 18. The idler wheel 163 is always meshed with the main gear 153, thereby converting the reciprocating rotation of the main gear 153 into the unidirectional rotation of the first auxiliary gear 18 (or the second auxiliary gear 20 after being transmitted by it). Through the ingenious gear and slide 162 limiting structure, the reciprocating input motion is converted into a continuous output in a single direction, ensuring the constancy of the rotation direction of the placement cylinder 21 and the internal wax block 22.

[0036] like Figure 1 and Figure 2 As shown, the yarn guiding assembly includes an electric guide rail 91, an electric slider 92, a fixed plate 93, a guide seat 94, and a guide hole 95. The electric guide rail 91 is fixedly installed inside the frame 1, the electric slider 92 is slidably installed on the outside of the electric guide rail 91, the fixed plate 93 is fixedly installed on the top of the electric slider 92, the guide seat 94 is fixedly installed on the top of the fixed plate 93, and the guide hole 95 is opened through the side of the guide seat 94. The two ends of the connecting rod 14 are fixed to the moving base 132 and the electric slider 92, respectively. The control panel 4 controls the electric guide rail. The electric guide rail 91 drives the electric slider 92 to reciprocate at a uniform speed. The electric slider 92 drives the moving seat 132 of the waxing mechanism to move synchronously through the connecting rod 14. At the same time, the guide seat 94 and its guide hole 95 fixed on the electric slider 92 guide the yarn for transverse yarn laying. The electric guide rail 91 drives the movement with high precision and controllable speed. The connecting rod 14 rigidly connects the moving seat 132 and the electric slider 92, ensuring strict synchronization between the waxing point and the yarn guiding point, improving the consistency of yarn tension and the forming quality of the package.

[0037] like Figures 1-5As shown, the guiding assembly includes a fixed plate 51, a fixed frame 52, a bushing 53, a support shaft 54, and a roller 55. There are two fixed plates 51, both of which are fixed to the top of the housing 2. The fixed frame 52 is fixed to the fixed plate 51. The bushing 53 is fixed to the side of the fixed frame 52. The support shaft 54 ​​is rotatably positioned between the two bushings 53. The roller 55 is fixed to the outside of the support shaft 54. The thick yarn passes around the roller 55 fixed to the support shaft 54. The support shaft 54 ​​rotates within the bushing 53, providing a certain gripping and guiding effect on the thick yarn, allowing it to be conveyed to the rear end at a certain position and angle. Through the simple roller 55 structure, the path of the fed fiber sliver is regulated, reducing unexpected shaking and deviation of the thick yarn, and providing good feeding conditions for the stability of subsequent eddy current twisting. The structure is simple and reliable.

[0038] like Figures 1-5 As shown, two fixing rods 56 are fixedly installed on the inner side of the housing 2, and guide cylinders 57 are fixedly installed on the sides of the two fixing rods 56. The longitudinal section of the guide cylinder 57 is a cone shape that is narrow at the bottom and wide at the top, and the bottom end of the guide cylinder 57 extends to the feed inlet of the feeding component. The cone shape of the guide cylinder 57 forms a gradually narrowing channel, which gradually gathers, constrains and precisely guides the yarn drawn from the lower end of the roller 55 to the feed inlet of the feeding component. This can effectively prevent the thick yarn from drifting or shaking due to airflow or tension changes after it is drawn out, and ensure that the yarn enters the subsequent process in a vertical and centered state, reducing the occurrence of yarn breakage and defects.

[0039] like Figures 1-6 As shown, the transmission assembly includes synchronous pulleys 61, synchronous belts 62, limiting rollers 63, and a drive motor 64. Multiple synchronous pulleys 61 are provided, all rotatably mounted inside the housing 2. The synchronous belt 62 is fitted over the outer sides of the synchronous pulleys 61. The limiting rollers 63 are located at the corners of the synchronous belt 62 and are in contact with it. The drive motor 64 is fixed inside the housing 2, and its output end is connected to the last synchronous pulley 61. The drive motor 64 drives the synchronous pulleys 61 to rotate, transmitting power to the other synchronous pulleys 61 via the synchronous belt 62. The limiting rollers 63 are used to tension and change the direction of the synchronous belt 62, ensuring smooth transmission. All synchronous pulleys 61 are connected to the drive gear 74 of the feeding assembly via a second fixed shaft 73. The synchronous belt 62 transmission provides smooth operation, low noise, and buffers load impacts. Multiple feeding rollers 76 are driven by a single motor, resulting in high transmission efficiency, a compact structure, and good synchronization.

[0040] like Figures 1-6As shown, the feeding assembly includes driven gears 71, a first fixed shaft 72, a second fixed shaft 73, a driving gear 74, comb teeth 75, and a feeding roller 76. Multiple driven gears 71 are provided, evenly spaced and rotatably connected to the inner wall of the housing 2. The first fixed shaft 72 is fixed to each driven gear 71, and the second fixed shaft 73 is fixed to each synchronous pulley 61 not connected to the drive motor 64. The driving gear 74 is sleeved on the outside of each second fixed shaft 73 and meshes with the corresponding driven gear 71. The feeding roller 76 is fixed to the ends of the first fixed shaft 72 and the second fixed shaft 73. The comb teeth... The 75 is fixedly installed on the outside of the bottom feed roller 76 and is distributed circumferentially around the feed roller 76. The power of the synchronous pulley 61 is transmitted to the drive gear 74 through the second fixed shaft 73. The drive gear 74 meshes with the driven gear 71, driving the first fixed shaft 72 and all feed rollers 76 to rotate synchronously in opposite directions, thereby clamping and conveying the fiber strip. The comb teeth 75 on the bottom feed roller 76 help to loosen the fiber. The multi-roller design forms a continuous gripping and stretching zone, and the conveying is stable and uniform. The gear meshing transmission ensures that the rotation speed of each feed roller 76 is strictly synchronized, avoiding accidental stretching or accumulation of the fiber strip. The comb teeth 75 can further comb the fiber and improve the feeding quality.

[0041] like Figures 1-8 As shown, the winding assembly includes a fixed base 81, a servo motor 82, a first connecting shaft 83, a limiting groove 84, a slot 85, a spring 86, a slide rod 87, a second connecting shaft 88, a docking rod 89, a winding roller 810, and a docking groove 811. The fixed base 81 is fixedly disposed inside the frame 1. The servo motor 82 is mounted on one end of the fixed base 81. The first connecting shaft 83 is rotatably disposed on the other end of the fixed base 81. The slot 85 is opened at the end of the first connecting shaft 83. The limiting groove 84 is opened inside the slot 85. The spring 86 is disposed inside the slot 85. The slide rod 87 is slidably disposed inside the slot 85 and the limiting groove 84. The two ends of the spring 86 are fixed to the slot 85 and the slide rod 87, respectively. The second connecting shaft 88 is mounted on the output end of the servo motor 82. The docking rod 89 is fixed to the output end of the servo motor 82. The take-up roller 810 is positioned between two connecting rods 89 and is located at the opposite ends of the slide rod 87 and the second connecting shaft 88. The connecting groove 811 is opened at both ends of the take-up roller 810 and is adapted to the connecting rod 89. The servo motor 82 drives the second connecting shaft 88 to rotate, and the power is transmitted to the take-up roller 810 through the connecting rod 89, causing it to rotate at high speed for winding. The spring 86 and slide rod 87 at the end of the first connecting shaft 83 provide a certain buffering and self-adaptive capability, which facilitates the installation and disassembly of the take-up roller 810. The servo motor 82 ensures that the winding speed is accurately controllable. The cooperation between the connecting rod 89 and the connecting groove 811 makes it easy to install and remove the take-up roller 810. The elastic buffer structure can adapt to the slight changes when the package diameter increases, protect the yarn from excessive tension damage, and ensure good package formation.

[0042] The specific working process of this invention is as follows: During operation, the thick yarn first passes over roller 55, is collected by guide cylinder 57, and is then clamped by oppositely rotating feed rollers 76 and fed into vortex twisting chamber 3 to complete twisting into yarn. The formed yarn is drawn out from the twisting chamber, passes through the yarn-threading hole on the moving seat 132, and adheres tightly to the surface of wax block 22 placed in the rotating placement cylinder 21. It is then guided to take-up roller 810 through guide hole 95 of guide seat 94. Control panel 4 controls electric guide rail 91 to drive electric slider 92 to reciprocate at a uniform speed. Electric slider 92 drives moving seat 132 to slide synchronously on limit rod 131 of fixed frame 12 through connecting rod 14. During reciprocating motion, the main gear 153 fixed thereon meshes with the rack 151 inside the fixed frame 12, thereby generating alternating forward and reverse rotation. This rotational motion is transmitted through the idler gear 163, which is always meshed with the main gear 153. The idler gear 163 is mounted on the slide block 162, which can slide within the arc-shaped limiting frame 161. Its sliding position is determined by the moving direction of the moving seat 132. When the moving seat 132 moves to the right, the slide block 162 slides to the left end of the limiting frame 161, and the idler gear 163 meshes with the second auxiliary gear 20. When it moves to the left, it slides to the right end and meshes with the first auxiliary gear 18 fixed at the top of the positioning shaft 17. Since the first auxiliary gear 18 and the second auxiliary gear 20 fixed on the hollow shaft 19 are always meshed, no matter how the main gear 153 rotates, the power transmitted through the idler gear 163 will eventually drive the second auxiliary gear 20, together with the placement cylinder 21 on its top and the wax block 22 inside, to rotate continuously in one direction, so as to avoid the yarn from becoming loose due to reverse rotation. At the same time, the servo motor 82 drives the second connecting shaft 88, which drives the take-up roller 810 to rotate through the docking rod 89, and winds the waxed yarn into a cylinder.
