Description

Technical Field

[0001] This invention relates to the field of cashmere spinning technology, specifically to an intelligent cashmere spinning equipment with automatic twist adjustment and its spinning process. Background Technology

[0002] Cashmere spinning equipment is a specialized textile machinery used to process cashmere fibers into yarn. Cashmere fibers, known as the "Queen of Fibers" due to their fineness, softness, and excellent warmth retention, are widely used in the production of high-end textiles. In the cashmere spinning process, the fiber slivers undergo processes such as drafting, twisting, and winding to ultimately form yarns with a certain strength and twist to meet the requirements of subsequent weaving processes. Ring spinning is currently the most widely used and technologically mature spinning method, and it is also the main process form for cashmere spinning. Specifically, after the yarn is output from the front roller nip, it passes through the guide hook and traveler in sequence, and is finally wound onto a high-speed rotating bobbin. Depending on the twisting section, the yarn path is usually divided into three functional sections: the spinning section from the front roller nip to the guide hook, the air ring section from the guide hook to the traveler, and the winding section from the traveler to the bobbin. However, in actual production, the yarn guide hook, as a fixed contact point in the yarn path, generates significant frictional resistance to the high-speed moving yarn. This friction causes the twist to be significantly "intercepted" and "consumed" during transmission. That is, when the twist is transmitted from the loop section to the spinning section, it is attenuated at the yarn guide hook, making the actual twist of the spinning section significantly lower than the theoretical twist of the loop section. This phenomenon is known as the "twist trap" effect in the textile engineering field. The existence of twist trap directly leads to insufficient yarn strength in the spinning section, which can easily cause quality problems such as yarn breakage and hairiness during subsequent twisting and winding. This problem is particularly prominent for cashmere fibers with short fiber length and low strength, seriously affecting yarn quality and production efficiency. To address this, we propose an intelligent cashmere spinning equipment and its spinning process with automatic twist adjustment. Summary of the Invention

A square iron sheet is fixedly installed at the other end of the steel shaft, and a plastic spring is connected between the square iron sheet and the outer wall of the rotating sleeve.

[0008] Preferably, a plurality of trapezoidal protrusions are fixedly installed on the inner wall of the movable sleeve, and the ball bearings at the end of the extension shaft are located on the movement trajectory of the trapezoidal protrusions.

[0009] Preferably, the monitoring component includes a support fixedly mounted on a bracket, and a support rod frame rotatably connected to the support is mounted on the support. One end of the support rod frame is mounted on a rotating shaft rotatably connected to it via a bearing, and a test wheel with a V-groove is fixedly mounted on the rotating shaft. The test wheel is in contact with the yarn.

[0010] Preferably, an arc-shaped plate frame is fixedly installed on the support rod frame, and the arc-shaped plate frame is arranged in a stepped manner. Multiple sensing elements are fixedly installed on the arc-shaped plate frame along the step direction, and the distance between each sensing element and the axis of rotation varies with the step level.

[0011] Preferably, a plurality of insertion frames are fixedly installed at one end of the rotating shaft, and a sliding panel that is slidably connected to the inner wall of the insertion frame is installed inside the insertion frame. A connecting shaft is fixedly installed on the sliding panel. One end of the connecting shaft passes through the inner wall of the insertion frame and extends to the outside. A spring body is connected between the insertion frame and the sliding panel. A trigger shaft is rotatably installed at the end of the connecting shaft located outside the insertion frame. The trigger shaft passes through the arc-shaped plate frame during movement.

[0012] Preferably, the inner wall of the metal sheet is provided with a plurality of flexible protrusions, and the radius and number of teeth of the gear mechanism are both greater than the number of teeth and radius of the meshing gear.

[0013] A spinning process for an intelligent, automatically twist-adjustable cashmere spinning machine specifically includes the following steps: S1. The yarn is output from the spinning section and is transmitted to the yarn forming section through the yarn guide hook. Before the yarn passes through the yarn guide hook, the yarn passes through the V-shaped groove of the test wheel. The test wheel and the yarn are in contact. The movement of the yarn drives the test wheel to rotate. S2. When the test wheel rotates, it drives the rotating shaft to rotate synchronously. The insertion frame on the rotating shaft rotates accordingly. The sliding panel inside the insertion frame slides outward under the action of centrifugal force. The magnitude of the centrifugal force depends on the rotation speed of the rotating shaft. The higher the rotation speed of the rotating shaft, the greater the centrifugal force and the farther the sliding panel moves outward. S3. When the sliding panel moves outward, it drives the connecting shaft and the trigger shaft to move outward synchronously. The rotating shaft continues to rotate, causing the trigger shaft to make a circular motion. When the trigger shaft moves outward a sufficient distance, its end contacts the surface of the arc-shaped frame during the movement, and under the guidance of the arc-shaped frame, it passes through the sensing elements of different steps on the arc-shaped frame in sequence, triggering the corresponding sensing elements to generate signals. S4. Determine the twisting effect of the yarn at the yarn guide hook based on the number of triggers of the sensing elements; control the motor and electromagnet to work based on the number of triggers of the sensing elements. S5. When the yarn twisting effect does not meet the standard, start the motor. Under the action of the gear mechanism and meshing gear, the rotating sleeve will rotate. At the same time, control the electromagnet to be energized, which will generate an attraction force on the annular iron plate. That is, the movable sleeve moves in the detachable sleeve. The trapezoidal protrusion on the movable sleeve contacts the ball at the end of the corresponding extension shaft, pushing the metal sheet to contact the yarn surface. Under the drive of the rotating sleeve, an auxiliary twisting effect is applied to the yarn. S6. As the current flowing through the electromagnet increases, the magnet body on the movable sleeve moves to the position corresponding to the square iron piece. The magnet body generates a repulsive force on the square iron piece, pushing the steel shaft to move towards the arc-shaped elastic sheet. This causes the arc-shaped elastic sheet to undergo elastic deformation and come into contact with the yarn surface. Under the combined action of the silicone sleeve, the metal sheet, and the flexible protrusion, a strong twisting effect is applied to the yarn.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a monitoring component, guides the yarn through the V-groove of the test wheel before it passes the yarn guide hook. The test wheel maintains contact with the yarn, and the movement of the yarn drives the test wheel to rotate. When the yarn twist is high, the structure is compact, the surface fibers have a high degree of interlocking with the V-groove, the friction is high, and the test wheel speed is high. When the yarn twist is low, the structure is loose, the friction with the V-groove is low, and the test wheel speed is low. Thus, the actual twist state of the yarn at the yarn guide hook is indirectly reflected by the change in the speed of the test wheel, realizing real-time and accurate perception of the twist status. Moreover, the test wheel adopts a V-groove structure to contact the yarn, with a moderate contact area, sensitive response, and no additional damage to the yarn. 2. This invention controls the motor start / stop and the electromagnet charge based on the number of triggers of the sensing element, achieving multi-level twisting compensation. When the number of triggers is small, the electromagnet drives the movable sleeve to move with a small charge, and the trapezoidal protrusion pushes part of the metal sheet to contact the yarn for auxiliary twisting. When the number of triggers is extremely small, the electromagnet drives the movable sleeve to move to the farthest position with a large charge. At the same time, all the metal sheets are in contact with the yarn, and the magnet body generates a repulsive force on the square iron sheet, pushing the arc-shaped elastic sheet through the steel shaft to deform and make it in close contact with the yarn. The silicone sleeve, flexible protrusion and metal sheet work together to apply strong twisting effect, effectively compensating for the twisting effect at the yarn guide hook, ensuring that the yarn in the spinning section has sufficient twist and strength, significantly reducing yarn breakage and hairiness, and improving yarn quality and production efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-12The present invention provides a technical solution: an intelligent cashmere spinning equipment with automatic twist adjustment, including a spinning machine body 1, a plurality of spinning devices 2 are provided on the spinning machine body 1, each spinning device 2 is equipped with a frame 21, and a plurality of spinning sections 22 and yarn forming sections 23 are provided on the frame 21. The spinning sections 22 and yarn forming sections 23 are existing technologies, and therefore the present invention does not describe them in detail. A yarn guide hook 24 is provided between the spinning section 22 and the yarn forming section 23. The yarn guide hook 24 is fixedly installed on a support 3 and is used to guide the yarn from the spinning section 22 to the yarn forming section 23. A monitoring component 4 is provided on the support 3 above the yarn guide hook 24. The monitoring component 4 is used to monitor the twist status of the yarn in real time. Furthermore, the monitoring component 4 includes a support 41 fixedly mounted on the bracket 3, a support rod 42 mounted on the support 41, and a rotatable connection between the support rod 42 and the support 41, allowing the support rod 42 to swing around the support 41 at a certain angle. The support rod 42 and the support 41 are fixed together by a nut. A rotating shaft 43 is mounted on one end of the support rod 42, and the rotating shaft 43 is connected to the support rod 42 through a bearing to ensure that the rotating shaft 43 can rotate flexibly. A test wheel 44 is fixedly mounted on the rotating shaft 43, and a V-shaped groove is formed on the outer circumference of the test wheel 44. The yarn passes through the V-shaped groove and interacts with the test wheel 44. 4. Maintaining contact: The V-groove design effectively guides the yarn while increasing the contact area between the yarn and the test wheel 44. This allows the test wheel 44 to respond sensitively to the yarn's movement. When the yarn twist is high, its structure is compact, the surface fibers are arranged regularly, and the engagement with the V-groove is high, resulting in greater friction and effectively driving the test wheel 44 to rotate at high speed. Conversely, when the yarn twist is low, the yarn is loose and has more surface hairs, reducing the friction with the V-groove and causing the test wheel 44 to rotate at a lower speed. Thus, the actual twist of the yarn at the guide hook 24 can be indirectly reflected by the change in the rotational speed of the test wheel 44.

[0019] Furthermore, a stepped arc-shaped plate frame 45 is fixedly installed on the support rod frame 42. Multiple sensing elements 46 are sequentially installed on the arc-shaped plate frame 45 along the stepped direction. The distance between each sensing element 46 and the axis of the rotating shaft 43 increases with each step. That is, the sensing elements 46 on different steps are at different distances from the axis of the rotating shaft 43. This stepped arrangement allows the sensing elements 46 to sense the movement state of the rotating shaft 43 at different radial positions. Multiple insertion frames 47 are fixedly installed at one end of the rotating shaft 43. The insertion frames 47 have a hollow structure, and a sliding panel 48 is installed inside each insertion frame 47. The sliding panel 48 is connected to the insertion frame 47. The sliding panel 48 can move within the frame 47 by sliding the inner wall of the frame 47. A connecting shaft 49 is fixedly installed on the sliding panel 48. One end of the connecting shaft 49 passes through the inner wall of the frame 47 and extends to the outside of the frame 47. A spring body 40 is connected between the frame 47 and the sliding panel 48. In its natural state, the spring body 40 keeps the sliding panel 48 in the inner position of the frame 47. A trigger shaft 401 is rotatably installed on the outer end of the connecting shaft 49. The trigger shaft 401 can pass through the arc-shaped plate frame 45 during movement and make contact with the sensing element 46 on the arc-shaped plate frame 45. When the test wheel 44 rotates with the yarn, the shaft 43 rotates synchronously, and the frame 47 rotates accordingly. Under the action of centrifugal force, the sliding panel 48 overcomes the tension of the spring body 40 and slides outward, driving the connecting shaft 49 and the trigger shaft 401 to move outward. If the yarn twist is high and the test wheel 44 rotates fast, the centrifugal force is large, and the trigger shaft 401 moves outward with a large amplitude, which can reach the sensing element 46 located further away on the arc-shaped frame 45. Conversely, if the yarn twist is low and the test wheel 44 rotates slowly, the centrifugal force is small, and the trigger shaft 401 can only reach the sensing element 46 near the shaft center, or even fail to trigger any sensing element 46. The number of triggers of the sensing element 46 can be used to determine the twisting effect of the current yarn at the guide hook 24.

[0020] Above the first bracket 3, a second bracket 25 is also provided. The second bracket 25 is also fixedly installed on the frame 21. A rotating sleeve 5 is installed on the second bracket 25. The rotating sleeve 5 and the second bracket 25 are rotatably connected. A meshing gear 51 is fixedly installed on the outer wall of the rotating sleeve 5. At the same time, a motor 26 is fixedly installed on the second bracket 25. A gear mechanism 27 is fixedly installed at the output end of the motor 26. The gear mechanism 27 and the meshing gear 51 are in a meshing state. When the motor 26 starts, the gear mechanism 27 drives the meshing gear 51 to rotate, so that the rotating sleeve 5 can be rotated controllably on the second bracket 25. The radius and number of teeth of the gear mechanism 27 are both greater than those of the meshing gear 51, thereby achieving deceleration and torque increase, ensuring that the rotating sleeve 5 rotates stably. The rotating sleeve 5 has multiple metal sheets 6 inside, which are arc-shaped and adapted to the shape of the yarn. Each metal sheet 6 has a connecting part 7 between itself and the inner wall of the rotating sleeve 5. The metal sheet 6 is installed in the rotating sleeve 5 through the connecting part 7 and can move radially relative to the rotating sleeve 5. Multiple flexible protrusions 63 are installed on the inner wall of the metal sheet 6. The flexible protrusions 63 are made of soft material. When the metal sheet 6 comes into contact with the yarn, the flexible protrusions 63 can increase the friction between the metal sheet and the yarn and avoid damage to the yarn. An arc-shaped elastic sheet 61 is also installed at one end of each metal sheet 6. The arc-shaped elastic sheet 61 has good elastic deformation ability. A silicone sleeve 62 is fitted on the outer wall of the arc-shaped elastic sheet 61. The surface of the silicone sleeve 62 has an appropriate coefficient of friction, which can provide good friction when in contact with the yarn and protect the yarn from damage. A detachable sleeve 52 is fixedly installed on the outer wall of the rotating sleeve 5. The detachable sleeve 52 rotates synchronously with the rotating sleeve 5. A movable sleeve 53 is installed inside the detachable sleeve 52. The movable sleeve 53 is slidably connected to the inner wall of the detachable sleeve 52, so that the movable sleeve 53 can move axially within the detachable sleeve 52. A spring part 54 is connected between the bottom of the movable sleeve 53 and the bottom inner wall of the detachable sleeve 52. In its natural state, the spring part 54 keeps the movable sleeve 53 in the lower position of the detachable sleeve 52. An annular iron plate 55 is fixedly installed on the top of the movable sleeve 53. An electromagnet 56 is fixedly installed on the top inner wall of the detachable sleeve 52. When the electromagnet 56 is energized, it generates an attractive force on the annular iron plate 55, thereby driving the movable sleeve 53 to move upward, and the spring part 54 is stretched accordingly.

[0021] Furthermore, the connecting part 7 includes an extension shaft 71 fixedly mounted on the metal sheet 6. The end of the extension shaft 71 penetrates the inner wall of the rotating sleeve 5 and extends into the interior of the detachable sleeve 52. The extension shaft 71 and the inner wall of the rotating sleeve 5 are slidably connected, allowing the extension shaft 71 to move in the radial direction. A return spring 72 is connected between the end of the extension shaft 71 and the outer wall of the rotating sleeve 5. In its natural state, the return spring 72 pulls the extension shaft 71 away from the yarn. A ball bearing is embedded in the end of the extension shaft 71. The ball can roll flexibly. Multiple trapezoidal protrusions 57 are fixedly installed on the inner wall of the movable sleeve 53. The trapezoidal protrusions 57 have a trapezoidal structure and their inclined surface design allows the ball to be pushed smoothly when it contacts the trapezoidal protrusions 57. The ball at the end of the extension shaft 71 is located on the movement trajectory of the trapezoidal protrusions 57. When the movable sleeve 53 moves axially, the trapezoidal protrusions 57 can contact the ball and apply force to it, pushing the extension shaft 71 to move in the direction of the yarn, and finally making the flexible protrusions 63 on the inner wall of the metal sheet 6 contact the yarn and apply auxiliary twisting force. A steel shaft 8 is mounted on the rotating sleeve 5 and is slidably connected to its inner wall. One end of the steel shaft 8 is close to the arc-shaped elastic sheet 61 and is located on the movement trajectory of the arc-shaped elastic sheet 61. A square iron piece 81 is fixedly mounted on the other end of the steel shaft 8. A plastic spring 82 is connected between the square iron piece 81 and the outer wall of the rotating sleeve 5. In its natural state, the plastic spring 82 keeps the steel shaft 8 away from the arc-shaped elastic sheet 61. The square iron piece 81 is located on the movement trajectory of the magnet body 58. When the movable sleeve 53 moves axially, the magnet body 58 can move to the position corresponding to the square iron piece 81 and generate a magnetic force on the square iron piece 81.

[0022] Specifically, during the spinning process of cashmere yarn, the fiber sliver is output from the spinning section 22, passes through the yarn guide hook 24, and is transmitted to the yarn forming section 23. Before the yarn passes through the yarn guide hook 24, it passes through the V-groove of the test wheel 44 in the monitoring component 4. The test wheel 44 is in contact with the yarn. The movement of the yarn causes the test wheel 44 to rotate. The twist of the yarn directly affects the magnitude of the friction between it and the V-groove of the test wheel 44. When the yarn twist is low, the yarn structure is loose, the interlocking degree between the surface fibers and the V-groove is poor, and the yarn slides in the V-groove, reducing the friction applied to the test wheel 44. The rotation speed of the test wheel 44 is correspondingly reduced. Therefore, by detecting the rotation speed of the test wheel 44, the twist status of the yarn at the yarn guide hook 24 can be indirectly determined. When the test wheel 44 rotates, it drives the rotating shaft 43, which is fixedly connected to it, to rotate synchronously. The insertion frame 47 on the rotating shaft 43 rotates accordingly. The sliding panel 48 inside the insertion frame 47 is subjected to centrifugal force. The magnitude of the centrifugal force is proportional to the rotational speed of the rotating shaft 43. The higher the rotational speed, the greater the centrifugal force. When the centrifugal force is large enough, the sliding panel 48 overcomes the tension of the spring body 40 and slides outward along the insertion frame 47. When the sliding panel 48 moves outward, it drives the connecting shaft 49 and the trigger shaft 401 to move outward synchronously. The rotating shaft 43 continues to rotate, and the trigger shaft 401 moves in a circular motion with the rotating shaft 43. When the trigger shaft 401 passes the arc-shaped plate frame 45, if the trigger shaft 401 touches the arc-shaped plate frame 45, the trigger shaft 401 will move outward. The trigger shaft 401 moves outward a sufficient distance, and its end will contact the surface of the arc-shaped frame 45. Since the arc-shaped frame 45 is set in a stepped shape, the trigger shaft 401 will pass through the sensing elements 46 on different steps in sequence during rotation. After the trigger shaft 401 contacts the arc-shaped frame 45, it will adjust its angle under the guidance of the arc-shaped frame 45, and its end will slide along the surface of the arc-shaped frame 45. The number of sensing elements 46 triggered varies depending on the different steps the trigger shaft 401 passes through. Specifically, when the yarn twist is high, the test wheel 44 rotates fast, the shaft 43 rotates at a high speed, the sliding panel 48 experiences a large centrifugal force, and moves a long distance outward. The trigger shaft 401 has a large radius of motion and can contact higher-level sensing elements 46 during rotation, triggering more sensing elements 46. When the yarn twist is low, the test wheel 44 rotates slowly, the shaft 43 rotates at a low speed, the sliding panel 48 experiences a small centrifugal force, and moves a short distance outward. The trigger shaft 401 has a small radius of motion and can only contact lower-level sensing elements 46, triggering fewer sensing elements 46. When the yarn twist is extremely low, the centrifugal force is insufficient to overcome the tension of the spring body 40, the sliding panel 48 remains in the inner position, and the trigger shaft 401 cannot contact any sensing elements 46 during rotation, so all sensing elements 46 are not triggered. The number of triggers of the sensing element 46 can accurately determine the twisting effect of the yarn at the guide hook 24. For ease of understanding, the following example is used: when none of the three sensing elements 46 are triggered, it indicates the worst yarn twisting effect; when one sensing element 46 is triggered, it indicates the relatively poor yarn twisting effect; when two sensing elements 46 are triggered, it indicates the acceptable yarn twisting effect; when all three sensing elements 46 are triggered, it indicates the good yarn twisting effect. When all three sensing elements 46 are triggered, it indicates the good yarn twisting effect at the guide hook 24, and no intervention is required. At this time, the motor 26 does not start, the rotating sleeve 5 remains stationary, the metal sheet 6 does not contact the yarn, and the yarn passes through normally. When two sensing elements 46 are triggered, it indicates that the yarn twisting effect is acceptable. However, to further improve yarn quality and reduce yarn breakage and hairiness, auxiliary twisting of the yarn is required. Motor 26 is started, driving gear mechanism 27 to rotate. Gear mechanism 27 drives meshing gear 51, causing rotating sleeve 5 to begin rotating on support 25. Simultaneously, electromagnet 56 is energized with the first current, generating an attractive force on the annular iron plate 55, driving movable sleeve 53 to move a certain distance towards electromagnet 56. As movable sleeve 53 moves, two of the trapezoids on its inner wall... The trapezoidal protrusion 57 contacts the ball bearings at the ends of the two corresponding extension shafts 71. The inclined surface of the trapezoidal protrusion 57 pushes the ball bearings, causing the extension shaft 71 to move towards the yarn direction against the tension of the return spring 72. This causes the two corresponding metal sheets 6 to move closer to the yarn and eventually contact the yarn surface. The flexible protrusions 63 on the inner wall of the metal sheets 6 contact the yarn, increasing the friction between them. Driven by the rotating sleeve 5, the two metal sheets 6 rotate synchronously with the sleeve, applying an auxiliary force to the yarn in the same direction as the twisting, helping the twist overcome the resistance of the yarn guide hook 24 and transmit forward. When one of the sensing elements 46 is triggered, it indicates that the yarn twisting effect is relatively poor and a stronger auxiliary twisting effect is needed. The current of the electromagnet 56 is increased to the second current, and the attraction force on the movable sleeve 53 increases. It continues to move a further distance towards the electromagnet 56. After the movable sleeve 53 moves further, the remaining trapezoidal protrusions 57 on its inner wall also contact the balls at the end of the corresponding extension shaft 71 and apply force, so that all the metal sheets 6 are in contact with the yarn surface. Driven by the rotating sleeve 5, the four metal sheets 6 simultaneously apply an auxiliary twisting effect to the yarn, which enhances the twisting effect. When none of the three sensing elements 46 are triggered, it indicates that the yarn twisting effect is the worst, and the strongest twisting compensation measures are required. At this time, the current of the electromagnet 56 increases to the third current, which is greater than the second current. The movable sleeve 53 experiences the greatest attraction force and moves the farthest. In this state, all the balls at the ends of the extension shafts 71 are in contact with the trapezoidal protrusions 57, and all four metal sheets 6 are in contact with the yarn. At the same time, when the movable sleeve 53 moves to its farthest position, the magnet body 58 on its inner wall moves to the position corresponding to the square iron piece 81. The magnet body 58 generates a repulsive force on the square iron piece 81, pushing the square iron piece 81 to move away from the movable sleeve 53. When in motion, the steel shaft 8 overcomes the elastic force of the plastic spring 82 and moves towards the arc-shaped elastic sheet 61. The end of the steel shaft 8 contacts the arc-shaped elastic sheet 61 and applies pressure to it, causing the arc-shaped elastic sheet 61 to undergo elastic deformation. The deformed arc-shaped elastic sheet 61 bends towards the yarn, and the silicone sleeve 62 on its outer wall comes into close contact with the yarn surface. The friction of the silicone sleeve 62 further enhances the constraint and driving ability of the yarn. At the same time, the speed of the motor 26 is increased, and the rotating sleeve 5 rotates at a higher speed. Under the combined action of the silicone sleeve 62, the metal sheet 6, and the flexible protrusion 63, a strong twisting effect is applied to the yarn, effectively compensating for the twisting effect at the yarn guide hook 24, and ensuring that the yarn in the spinning section has sufficient twist and strength.

[0023] A spinning process for an intelligent, automatically twist-adjustable cashmere spinning machine specifically includes the following steps: S1. The yarn is output from the spinning section 22 and is transmitted to the yarn forming section 23 through the yarn guide hook 24. Before the yarn passes through the yarn guide hook 24, the yarn passes through the V-shaped groove of the test wheel 44. The test wheel 44 is in contact with the yarn, and the movement of the yarn drives the test wheel 44 to rotate. S2. When the test wheel 44 rotates, it drives the rotating shaft 43 to rotate synchronously. The insertion frame 47 on the rotating shaft 43 rotates accordingly. The sliding panel 48 inside the insertion frame 47 slides outward under the action of centrifugal force. The magnitude of the centrifugal force depends on the rotation speed of the rotating shaft 43. The higher the rotation speed of the rotating shaft 43, the greater the centrifugal force and the farther the sliding panel 48 moves outward. S3. When the sliding panel 48 moves outward, it drives the connecting shaft 49 and the trigger shaft 401 to move outward synchronously. The rotating shaft 43 continues to rotate, causing the trigger shaft 401 to make a circular motion. When the trigger shaft 401 moves outward a sufficient distance, its end contacts the surface of the arc-shaped frame 45 during the movement, and passes through the sensing elements 46 of different steps on the arc-shaped frame 45 in sequence under the guidance of the arc-shaped frame 45, triggering the corresponding sensing elements 46 to generate signals. S4. Determine the twisting effect of the yarn at the yarn guide hook 24 based on the number of triggers of the sensing element 46; control the motor 26 and electromagnet 56 to work based on the number of triggers of the sensing element 46. S5. When the yarn twisting effect is not up to standard, start the motor 26. Under the action of the gear mechanism 27 and the meshing gear 51, the rotating sleeve 5 rotates. At the same time, control the electromagnet 56 to be energized, which generates an attraction force on the annular iron piece 55. That is, the movable sleeve 53 moves in the detachable sleeve 52. The trapezoidal protrusion 57 on the movable sleeve 53 contacts the ball at the end of the corresponding extension shaft 71, pushing the metal sheet 6 to contact the yarn surface. Under the drive of the rotating sleeve 5, an auxiliary twisting effect is applied to the yarn. S6. As the current flowing through the electromagnet 56 increases, the magnet body 58 on the movable sleeve 53 moves to the position corresponding to the square iron piece 81. The magnet body 58 generates a repulsive force on the square iron piece 81, pushing the steel shaft 8 to move towards the arc-shaped elastic sheet 61, causing the arc-shaped elastic sheet 61 to undergo elastic deformation and contact the yarn surface. Under the combined action of the silicone sleeve 62, the metal sheet 6, and the flexible protrusion 63, a strong twisting effect is applied to the yarn.
