[0002] Yarn is a basic material in the textile industry. It is made from natural or chemical fibers through specific processes and has various types and uses. Yarn false twist is a process in textile processing that forms a twist in opposite directions by fixing both ends and twisting the middle. Yarn false twist device is a key piece of equipment in textile processing used to improve yarn performance. It significantly improves the strength, elasticity and spinnability of yarn by applying temporary twist and optimizing fiber arrangement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a yarn false twisting device, including a false twisting chamber, a false twisting cylinder rotatably connected inside the false twisting chamber, and a limiting mechanism;

[0006] Limiting mechanism: It includes limiting cylinders, sliding grooves, movable seats and guide balls. The limiting cylinders are fixedly connected to the front and rear ends of the false twist cylinder. The end of the limiting cylinder away from the center of the false twist cylinder is provided with evenly distributed sliding grooves. The sliding grooves are slidably connected to the inside of the sliding grooves. The end of the movable seat near the central axis of the adjacent limiting cylinder is provided with a guide groove. The guide groove is rotatably connected to the inside of the guide groove. The outer arc surface of the guide ball is provided with an arc-shaped groove to limit the entry and exit of yarns of different diameters into and out of the false twist cylinder, and to ensure the stability of the yarn during the false twisting process.

[0007] Furthermore, the limiting mechanism also includes a rotating cylinder, a turntable, an inclined groove, a worm gear, and a worm. The rotating cylinder is rotatably connected to the outer surface of the inner cylinder of the limiting cylinder. The end of the rotating cylinder away from the center of the false twist cylinder is fixedly connected to a turntable. The interior of the turntable is provided with evenly distributed inclined grooves. The end of the moving seat near the center of the false twist cylinder is fixedly connected to a fixed shaft. The outer surface of the fixed shaft is slidably connected to the interior of the adjacent inclined groove. The right end of the limiting cylinder is rotatably connected to a worm gear. The middle of the outer surface of the rotating cylinder is fixedly connected to a worm gear. The worm gear is meshed with the adjacent worm gear to provide driving force for adjusting the position of the moving seat.

[0008] Furthermore, a controller is provided at the front end of the right side surface of the false twist chamber. The input terminal of the controller is electrically connected to an external power source to control various electrical appliances.

[0009] Furthermore, the false twist chamber has two fixed frames inside, which are rotatably connected to the front and rear ends of the outer surface of the false twist cylinder. Five conveying rollers are rotatably connected inside the false twist cylinder. The middle of the false twist cylinder has evenly distributed through holes. A driven gear ring is fixedly connected to the middle of the outer surface of the false twist cylinder. A motor is installed at the right end of the bottom wall of the false twist chamber. A drive gear is fixedly connected to the front end of the motor output shaft. The drive gear and the driven gear ring are meshed. The input end of the motor is electrically connected to the output end of the controller to realize the false twisting of the yarn.

[0010] Furthermore, a support plate is fixedly connected to the rear end of the false twist chamber, and a fixed column is fixedly connected to the rear end of the upper surface of the support plate. Symmetrically distributed telescopic columns are fixedly connected to the rear end of the top wall of the false twist chamber. The telescopic ends of the two telescopic columns are fixedly connected to the upper end of the pressure plate. An electric push rod is provided at the rear end of the false twist chamber. The telescopic end of the electric push rod is fixedly connected to the middle of the upper surface of the pressure plate. Ribs that are evenly distributed are fixedly connected to the middle of the upper surface of the support plate and the middle of the lower surface of the pressure plate. The input end of the electric push rod is electrically connected to the output end of the controller to realize the pressing of one end of the yarn, which facilitates the false twisting of the yarn.

[0011] Furthermore, the limiting cylinder has symmetrically distributed scale strips on the side surface away from the center of the false twist cylinder, and the uppermost movable seat has an indicator arrow fixedly connected to the side surface away from the center of the false twist cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This yarn false twisting device has the following advantages:

[0015] The worm gear mechanism enables the turntable to rotate. The rotation of the inclined groove pushes or pulls the moving seat to move inward or outward, ultimately adjusting the distance between the guide ball and the center axis of the limiting cylinder. This allows for the limiting of yarns of different diameters when entering and leaving the false twisting cylinder, ensuring the stability of the yarn during the false twisting process and preventing the yarn from shifting during the rotation of the false twisting cylinder, which would affect the false twisting quality of the yarn.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7This embodiment provides a technical solution: a yarn false twisting device, including a false twisting chamber 1, a false twisting cylinder 2 rotatably connected inside the false twisting chamber 1, a controller 17 provided at the front end of the right side surface of the false twisting chamber 1, the input end of the controller 17 being electrically connected to an external power supply, and also including a limiting mechanism 3;

[0026] Limiting mechanism 3 includes a limiting cylinder 31, a sliding groove 32, a movable seat 38, and a guide ball 39. The limiting cylinder 31 is fixedly connected to the front and rear ends of the false twist cylinder 2. The end of the limiting cylinder 31 away from the center of the false twist cylinder 2 is provided with a uniformly distributed sliding groove 32. The sliding seat 38 is slidably connected inside the sliding groove 32. The end of the movable seat 38 near the central axis of the adjacent limiting cylinder 31 is provided with a guide groove. The guide ball 39 is rotatably connected inside the guide groove. The outer arc surface of the guide ball 39 is provided with an arc groove 18. The limiting mechanism 3 also includes a rotating cylinder 33, a turntable 34, an inclined groove 35, a worm gear 36, and a worm 37. The rotating cylinder 33 is rotatably connected to the outer surface of the inner cylinder of the limiting cylinder 31. The end of the rotating cylinder 33 away from the center of the false twist cylinder 2 is fixedly connected with a sliding groove 32. The central axes of the turntable 34, false twist cylinder 2, limiting cylinder 31, rotating cylinder 33, and turntable 34 coincide. The interior of turntable 34 is provided with evenly distributed inclined grooves 35. A fixed shaft is fixedly connected to the end of the moving seat 38 near the center of false twist cylinder 2. The outer surface of the fixed shaft is slidably connected to the interior of the adjacent inclined groove 35. A worm gear 37 is rotatably connected to the right end of the limiting cylinder 31. A worm wheel 36 is fixedly connected to the middle of the outer surface of the rotating cylinder 33, and the worm wheel 36 meshes with the adjacent worm gear 37. Symmetrically distributed scale bars 15 are provided on the surface of the limiting cylinder 31 away from the center of false twist cylinder 2. An indicator arrow is fixedly connected to the surface of the uppermost moving seat 38 away from the center of false twist cylinder 2, and both scale bars 15 cooperate with the indicator arrow. Installation (In the initial state, the centers of the arc-shaped grooves 18 are all located on the inner diameter circles of the adjacent limiting cylinders 31. Since the distance between the center axis of the fixed shaft on the movable seat 38 and the center of the adjacent arc-shaped grooves 18 is fixed, the moving distance of the movable seat 38 is equal to the moving distance of the outer center of the arc-shaped grooves 18. When the movable seats 38 are all moved to their extreme positions, the centers of the three arc-shaped grooves 18 coincide with each other and are all located on the central axis of the adjacent limiting cylinders 31. Therefore, the stroke of the movable seat 38 and the guide ball 39 is the inner diameter radius of the limiting cylinder 31. Let the distance between the center of the arc-shaped grooves 18 and the central axis of the limiting cylinder 31 in the initial state be e, and the moving distance of the center of the arc-shaped grooves 18 be f. The distance between the center of the arc-shaped grooves 18 and the central axis of the limiting cylinder 31 in the current state is...) Let h = ef. The distance the indicator arrow moves is equal to the distance the center of the arc groove 18 moves. With a fixed stroke of the center of the arc groove 18, the functional relationship of h = ef is quantified and displayed through the scale bar 15. When h equals the yarn diameter, the worm 37 stops rotating. At this time, the three adjacent arc grooves 18 can achieve stable positioning of the yarn. According to the required false twist yarn diameter, the front worm 37 is rotated. The rotation of the front worm 37 drives the rotation of the front worm wheel 36. The rotation of the front worm wheel 36 drives the rotation of the front drum 33. The rotation of the front drum 33 drives the rotation of the front turntable 34. The rotation of the front turntable 34 drives the rotation of the three oblique grooves 35 on the front. When the front oblique groove 35 rotates clockwise...The inner wall of the inclined groove 35 on the front side pushes the adjacent fixed shaft to move, thereby causing the moving seats 38 on the front side to move towards the center of the limiting cylinder 31 within the adjacent sliding grooves 32. The movement of the moving seats 38 drives the adjacent guide balls 39 to move towards the center of the limiting cylinder 31. Simultaneously, the scale inside the scale bar 15 on the front side, which is on the same plane as the indicator arrow on the front side, represents the distance between the current guide ball 39 and the central axis of the limiting cylinder 31. When the guide ball 39 can stably limit the yarn, the worm gear 37 stops rotating. At this time, the yarn is positioned between the three arc-shaped grooves 18 on the front side, providing guidance for the longitudinal transmission of the yarn. This principle enables the position adjustment of the guide ball 39 on the rear side, achieving the limiting of yarns of different diameters entering and leaving the false twist cylinder 2, ensuring the stability of the yarn during the false twisting process, and preventing the yarn from shifting during the rotation of the false twist cylinder 2, which would affect the false twisting quality of the yarn.

[0027] Wherein: two fixed frames 4 are fixedly connected inside the false twist chamber 1. The interior of the two fixed frames 4 is rotatably connected to the front and rear ends of the outer surface of the false twist cylinder 2 respectively. Five conveying rollers 7 are rotatably connected inside the false twist cylinder 2. The middle part of the false twist cylinder 2 is provided with evenly distributed through holes. The middle part of the outer surface of the false twist cylinder 2 is fixedly connected with a driven gear ring 5. The right end of the bottom wall of the false twist chamber 1 is provided with a motor 6. The front end of the output shaft of the motor 6 is fixedly connected with a drive gear. The drive gear and the driven gear ring 5 are meshed and connected. The input end of the motor 6 is electrically connected to the output end of the controller 17.

[0028] The false twist chamber 1 is internally connected to a support plate 9 at its rear end. A fixed column 11 is fixedly connected to the rear end of the upper surface of the support plate 9. Symmetrically distributed telescopic columns 13 are fixedly connected to the rear end of the top wall of the false twist chamber 1. The telescopic ends of both telescopic columns 13 are fixedly connected to the upper end of the pressure plate 12. An electric push rod 14 is installed at the rear end of the false twist chamber 1. The telescopic end of the electric push rod 14 is fixedly connected to the middle of the upper surface of the pressure plate 12. (A laser rangefinder can be installed on the upper surface of the pressure plate 12. The laser rangefinder uses a commonly used laser rangefinder in existing technology. The controller 17 enables the operation of the laser rangefinder. The laser probe of the laser rangefinder emits a laser beam towards the top wall of the false twist chamber 1. Based on the speed of light and the time it takes for the laser to reflect back to the laser probe, the pressure at the current moment is calculated.) The real-time distance b between plate 12 and the top wall of false twist chamber 1, the distance a between the upper surface of support plate 9 and the top wall of false twist chamber 1, and the vertical height d of ribs 10 are all specified. Let c be the distance between support plate 9 and pressure plate 12, where c = ab - 2 * d. Since a and d are constants, c and b are linearly related. The real-time value of c can be obtained by measuring b. The laser rangefinder sends b to the signal receiving end of controller 17 in real time. Controller 17 substitutes the real-time data of b into c = ab - 2 * d. When c equals the yarn diameter, controller 17 stops the extension of electric push rod 14. Ribs 10 are uniformly distributed and fixedly connected to the middle of the upper surface of support plate 9 and the middle of the lower surface of pressure plate 12. The ribs 10 on the upper surface of support plate 9 and the lower surface of pressure plate 12 are also specified. The projections of the ribs 10 on the horizontal plane are perpendicular to each other. The input end of the electric push rod 14 is electrically connected to the output end of the controller 17. When the external traction device pulls the yarn to a designated position on the upper surface of the support plate 9, and the external detection device detects that the yarn has moved to the designated position, the controller 17 shuts off the external traction device and enables the electric push rod 14 to operate. The extension end of the electric push rod 14 extends and pushes the pressure plate 12 downward. The downward movement of the pressure plate 12 causes the extension end of the telescopic column 13 to extend, providing guidance for the movement of the pressure plate 12. The pressure plate 12 and the support plate 9 work together to press the yarn. At the same time, the ribs 10 on the upper and lower sides increase the stability of pressing the yarn. Then the controller 17 shuts off the electric push rod 14 and enables the motor 6 to operate. The output shaft of the motor 6 rotates. The drive gear rotates, which in turn drives the driven gear ring 5 to rotate. The driven gear ring 5 rotates, causing the false twist cylinder 2 to rotate between the two fixed frames 4. The rotation of the false twist cylinder 2 drives the conveyor roller 7 to rotate, which in turn drives the yarn inside the false twist cylinder 2 to rotate, thus achieving yarn twisting. An external detection device records the number of rotations of the false twist cylinder 2. When the false twist cylinder 2 rotates to a specified number of rotations, the yarn twist increases to a specified value. Then, the controller 17 shuts off the motor 6 and retracts the telescopic end of the electric push rod 14, causing the pressure plate 12 to move upward, ending the yarn limiting. Simultaneously, the controller 17 activates the external traction device to convey the twisted yarn out, then waits for the next section of yarn to be twisted. After the yarn leaves the false twist cylinder 2...The forward and reverse twists automatically cancel each other out due to yarn movement, and the overall twist returns to zero. However, the fibers have already developed a helical crimp structure due to the temporary twist, thus achieving false twist in the yarn.

[0029] Among them: the front end of the false twist chamber 1 is rotatably connected to a uniformly distributed feeding roller 8. Under the traction of the external traction device, the yarn passes through the interior of the false twist chamber 1 from front to back, and passes through the feeding roller 8, the false twist cylinder 2 and the support plate 9 in sequence. The yarn inside the false twist cylinder 2 is distributed in an S-shape under the action of the conveying roller 7.

[0030] Among them: the left end of the false twist chamber 1 is hinged to the chamber door 16.

[0031] The working principle of the yarn false twisting device provided by this utility model is as follows: During operation, the operator first places the false twisting chamber 1, the false twisting cylinder 2, and other mechanisms stably in a horizontal working area. After stable placement, the operator rotates the front worm 37 according to the required yarn diameter. The rotation of the front worm 37 drives the front worm wheel 36 to rotate, which in turn drives the front rotating cylinder 33 to rotate. The rotation of the front rotating cylinder 33 drives the front turntable 34 to rotate, which in turn drives the three front inclined grooves 35 to rotate. When the front inclined groove 35 rotates clockwise, the inner wall of the front inclined groove 35 pushes the adjacent fixed shaft to move, thereby causing the front movable seats 38 to move closer to the front within the adjacent sliding grooves 32. The movement of the limiting cylinder 31 and the moving seat 38 both drive the adjacent guide balls 39 to move closer to the center of the front limiting cylinder 31. Simultaneously, the scale inside the front scale bar 15, which is on the same plane as the front indicator arrow, represents the distance between the current guide ball 39 and the central axis of the limiting cylinder 31. When the guide ball 39 can stably limit the yarn, the worm gear 37 stops rotating. At this time, the yarn is positioned between the three arc-shaped grooves 18 on the front, providing guidance for the longitudinal transmission of the yarn. This principle enables the position adjustment of the rear guide ball 39, achieving the limiting of yarns of different diameters entering and leaving the false twist cylinder 2, ensuring the stability of the yarn during the false twisting process, and preventing the yarn from shifting during the rotation of the false twist cylinder 2, thus affecting the false twisting effect. The yarn is first twisted, and then, under the traction of the external traction device, it passes through the interior of the false twist chamber 1 from front to back, passing sequentially through the feeding roller 8, the false twist cylinder 2, and the support plate 9. The yarn inside the false twist cylinder 2 is distributed in an S-shape under the action of the conveying roller 7. When the external traction device pulls the yarn to a designated position on the upper surface of the support plate 9, and when the external detection device detects that the yarn has moved to the designated position, the controller 17 shuts down the external traction device and activates the electric push rod 14. The telescopic end of the electric push rod 14 extends and pushes the pressure plate 12 downward. The downward movement of the pressure plate 12 causes the telescopic end of the telescopic column 13 to extend, providing guidance for the movement of the pressure plate 12. The pressure plate 12 and the support plate 9 work together to hold the yarn, while the ribs 10 on the upper and lower sides increase the pressure on the yarn. To maintain stability, controller 17 then shuts off electric push rod 14 and starts motor 6. The output shaft of motor 6 rotates, driving the drive gear to rotate, which in turn drives the driven gear ring 5 to rotate. The driven gear ring 5 rotates, causing the false twist cylinder 2 to rotate between the two fixed frames 4. The rotation of the false twist cylinder 2 drives the conveyor roller 7 to rotate, which in turn drives the yarn inside the false twist cylinder 2 to rotate, thus achieving yarn twisting. External detection equipment records the number of rotations of the false twist cylinder 2. When the false twist cylinder 2 rotates to a specified number of rotations, the yarn twist increases to a specified value. Then, controller 17 shuts off motor 6 and retracts the telescopic end of electric push rod 14, causing pressure plate 12 to move upward, ending the yarn limiting. At the same time, controller 17 enables the operation of external traction equipment.The twisted yarn is fed out, and then waits for the next section of yarn to be twisted. When the yarn leaves the false twist cylinder 2, the forward and reverse twists automatically cancel each other out due to the yarn movement, and the overall twist returns to zero. However, the fibers have already formed a spiral curl structure due to the temporary twist, thus achieving false twist of the yarn.

[0032] It is worth noting that the controller 17 disclosed in the above embodiments can be selected, and the operation of the controller 17 motor 6 and electric push rod 14 both adopt methods commonly used in the prior art.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
