Description

Technical Field

[0001] The present application relates to the technical field of spinning, and in particular to a breakage automatic stop mechanism and a ring spinning device. Background Art

[0002] In the actual use of ring spinning devices, the phenomenon of broken ends is quite common, especially between the rollers and the rubber rollers, where the problem of broken ends is more prominent. In this critical area, the fiber strands are quickly stretched from their thick initial state to become thinner, and the force on the fibers changes dramatically here. Due to the differences in length and performance of the fibers themselves, it is difficult for fibers of different lengths and different properties to be subjected to completely uniform forces during the drafting process. Short fibers or fibers with weaker strength often find it difficult to withstand the greater tensile force here, and are prone to breakage due to exceeding their own bearing limit, which leads to the occurrence of broken ends. For example, when the coarse yarn enters the spinning process, the drafting multiple is usually large, and the tensile force on the fibers between the rollers and the rubber rollers is extremely obvious, so some relatively fragile fibers are prone to breakage in this area.

[0003] The existing ring spinning device has certain limitations in terms of structural design. Its rollers are usually connected in sequence with one or more rollers to achieve synchronous operation of rollers at different stations. Although this design can ensure the coordination of the overall production process, it exposes obvious disadvantages when facing end breakage. When an end break occurs, due to the connection method and operation mechanism of the entire roller system, it is impossible to pause the roller corresponding to the end break position alone. In this way, the broken spinning end is very easy to be entangled in the roller while the equipment continues to operate. This will not only affect the normal operation of the equipment, but may also cause further damage to the yarn quality. Summary of the invention

[0004] The purpose of the present application is to provide a yarn breakage automatic stop mechanism and a ring spinning device, in order to solve the problem of independent shutdown due to yarn breakage.

[0005] The present application provides a breakage automatic stop mechanism that adopts the following technical solution: it includes a machine body, a power assembly connected to an external power source, a first rod and a second rod rotatably connected to the machine body, a plurality of rubber rollers installed on the first rod, a roller mechanism installed on the second rod, a linkage mechanism connecting the first rod and the second rod, and a locking mechanism for limiting the rotation of the first rod, wherein the first rod rotates to drive the second rod to rotate in the opposite direction through the linkage mechanism; There are two limit states for the positions of the first rod and the second rod, namely an open state and a closed state; Closed state: the roller mechanism is in contact with the rubber roller, the power input end of the roller mechanism is connected with the power output end of the power assembly, the first rod falls into the locking mechanism, and the movement of the first rod is restricted by the locking mechanism; Open state: the roller mechanism is abutted and separated from the rubber roller, the power input end of the roller mechanism is disengaged from the power output end of the power assembly, and the first rod is disengaged from the locking mechanism.

[0006] By adopting the above technical solution, the first rod, the second rod and the linkage mechanism cooperate to control the working state of the roller mechanism and the rubber roller; when in the closed state, the roller mechanism abuts against the rubber roller, and the power input end of the roller mechanism is connected to the power output end of the power assembly. At this time, the power provided by the power assembly can be transmitted to the roller mechanism, causing it to start rotating. Under the joint action of the roller mechanism and the rubber roller, the fiber is clamped and drafted. The rubber roller exerts a certain pressure on the fiber by closely cooperating with the roller mechanism to ensure that the fiber can be smoothly stretched and thinned under the traction of the roller mechanism. When in the open state, the roller mechanism abuts against the rubber roller and separates, and the power input end of the roller mechanism is separated from the power output end of the power assembly. In this state, the power of the power assembly cannot be transmitted to the roller mechanism, and the roller mechanism stops rotating. At the same time, since the rubber roller and the roller mechanism are separated, the fiber is no longer clamped and drafted.

[0007] Optionally, the linkage mechanism includes a first connecting rod fixedly connected to the end of the first rod, a second connecting rod fixedly connected to the end of the second rod, and a third connecting rod rotatably connected to the body, the first connecting rod is provided with a first groove, and the end of the second connecting rod can move along the first groove, the third connecting rod is provided with a second groove, and the end of the first connecting rod can move along the second groove.

[0008] By adopting the above technical solution, the rotation of the first rod drives the first connecting rod to move, and the first groove on the first connecting rod guides the end of the second connecting rod to move accordingly. At the same time, the end of the first connecting rod moves along the second groove on the third connecting rod, and the movement is transmitted to the second connecting rod through the rotation of the third connecting rod. Under the joint action of the first connecting rod and the third connecting rod, the second connecting rod drives the second rod to rotate in the opposite direction of the first connecting rod; when the broken end signal is detected, the linkage mechanism can make the roller mechanism abut and separate from the rubber roller through the rotation of the first rod and the second rod, thereby preventing the broken spinning end from being entangled in the roller mechanism.

[0009] Optionally, the third connecting rod is fixedly connected to the first block, the third connecting rod is slidably connected to the second block, a driving spring is provided between the first block and the second block, and the driving spring forces the second block to abut against the first connecting rod.

[0010] By adopting the above technical solution, it is always in a compressed state, exerting a continuous thrust on the second block. This thrust forces the second block to abut against the first connecting rod, and makes the end of the first connecting rod be located at the bottom of the second groove. This action of the driving spring provides a pre-tightening force for the first rod and the second rod to always keep them open. When the yarn breaks, the driving spring can drive the first rod and the second rod to open.

[0011] Optionally, the roller mechanism includes a second rod fixedly connected to the second rod, a plurality of rollers rotatably connected to the second rod, a plurality of speed regulating components for adjusting the rotational speed of the rollers, and an input component capable of being connected to the output end of a power component; the input component transmits power to different rollers through different speed regulating components, and when the first rod and the second rod are in a closed state, the input component is connected to the power component.

[0012] By adopting the above technical scheme, the speed regulating component can distribute the power transmitted from the input component to different rollers according to a predetermined ratio, so as to achieve the speed difference between each roller; when the first rod and the second rod are in a closed state, the input component is connected to the power component, so that the power can be smoothly transmitted to the roller; when the first rod and the second rod are in an open state, the input component is disconnected from the power component; when the first rod and the second rod are in a closed state, the roller and the rubber roller work together to clamp and stretch the fiber. If a broken end occurs, the broken end self-stop mechanism will make the first rod and the second rod enter the open state, at which time the input component of the roller mechanism is disconnected from the power component, and the roller stops rotating. This fast response mechanism can effectively prevent the broken spinning end from being entangled in the roller roller, reducing equipment failures and the impact on yarn quality.

[0013] Optionally, the speed regulation assembly includes a rotating frame fixedly connected to the end of the roller roller, a sliding rod slidably connected to the rotating frame, a pulley block fixedly connected to the end of the sliding rod, and an adjustment unit that drives the sliding rod to move, the adjustment unit can synchronously drive all the sliding rods to move, all the pulley blocks are arranged at equal angles around the rotating frame, all the pulley blocks are combined into a pulley disk with adjustable diameter, and the pulley disk is connected to the input assembly through a belt drive.

[0014] By adopting the above technical solution, when the speed of the roller needs to be adjusted, the adjustment unit starts working and drives all the slide bars to move synchronously. Since the pulley block is fixed at the end of the slide bar, the movement of the slide bar will drive the pulley block to change its position. When the slide bar moves outward, the spacing between the pulley blocks increases, and the diameter of the pulley disc becomes larger; when the slide bar moves inward, the spacing between the pulley blocks decreases, and the diameter of the pulley disc becomes smaller. According to the principle of belt transmission, the change in the diameter of the pulley disc will cause the transmission ratio between it and the input component to change, thereby realizing the adjustment of the speed of the roller roller. For example, when the speed of the roller roller needs to be reduced, the adjustment unit moves the slide bar inward, the diameter of the pulley disc becomes smaller, and the speed of the roller roller will also be reduced accordingly when the speed of the input component remains unchanged. This diameter-adjustable pulley disc design realizes continuous adjustment of the speed of the roller roller.

[0015] Optionally, the adjusting unit includes a slider, an intermediate rod rotatably connected to the pulley block, a hollow rod fixedly connected to the rotating frame, and a screw rod arranged inside the hollow rod. The side of the hollow rod is provided with a plurality of through grooves connected to the interior. The slider is slidably connected to the inner wall of the hollow rod. The slider is threadably connected to the screw rod. The slider is provided with a connecting portion that passes through the through groove. The connecting portion is rotatably connected to the intermediate rod, and the end of the screw rod passes through the end of the hollow rod.

[0016] By adopting the above technical solution, when the screw rotates, the rotation of the screw is converted into the linear movement of the slider in the hollow rod due to the threaded connection between the slider and the screw. According to the rotation direction of the screw, the slider can move in different directions along the inner wall of the hollow rod. When the slider moves, the intermediate rod will change its angle as the slider moves through the rotation connection between the connecting part and the intermediate rod, thereby transmitting force to the end of the slider. Since the slider is slidably connected to the rotating frame, the position change of the slider will drive the pulley block to move, thereby adjusting the diameter of the pulley disc.

[0017] Optionally, the input component includes a rotating shaft rotatably connected to the second rod, the rotating shaft passes through the second rod, a plurality of driving pulleys are fixedly connected to the rotating shaft, the driving pulleys are connected to the pulley discs through belts, and a worm gear is provided at the rotating end.

[0018] By adopting the above technical solution, the power is first transmitted to the rotating shaft of the input component. The rotating shaft starts to rotate by connecting with the power source. The driving pulley fixed on the rotating shaft rotates with the rotating shaft, and the driving pulley is connected to the pulley disc in the speed regulating component through a belt to transmit the power to the pulley disc. Since the pulley disc is composed of multiple pulley blocks and the diameter is adjustable, according to the principle of belt transmission, pulley discs with different diameters will cause the transmission ratio between them and the driving pulley to change, thereby realizing the adjustment of the roller roller speed.

[0019] Optionally, the power assembly includes a power shaft connected to an external power source, a transmission shaft installed on the machine body, and a worm fixedly connected to the end of the transmission shaft. The transmission shaft and the power shaft are connected through a bevel gear transmission. When the first rod and the second rod are in a closed state, the worm is meshed with the worm wheel.

[0020] By adopting the above technical solution, the power shaft transmits power to the transmission shaft connected thereto. Since the transmission shaft and the power shaft are connected through a bevel gear transmission, the direction of the power changes during the transmission process. The rotation of the transmission shaft drives the worm fixed at its end to rotate. When the first rod and the second rod are in a closed state, the worm is meshed with the worm wheel, and the rotation of the worm transmits power to the worm wheel through meshing. The rotation of the worm wheel drives the rotating shaft in the input component to rotate, and then transmits power to the pulley disc in the speed regulating component through the driving pulley and belt, and finally drives the roller roller to rotate. When a broken yarn occurs, it is necessary to quickly stop the operation of the roller mechanism to prevent the broken yarn from further winding around the roller roller, and the worm and the worm wheel are disengaged to quickly stop the transmission of power.

[0021] Optionally, the locking mechanism includes a sensor, a frame fixedly connected to the machine body, and an actuator installed in the frame, the sensor is respectively installed on the first rod and the roller mechanism, when the first rod and the second rod are in a closed state, the first rod falls into the frame, and the output end of the actuator extends out to abut the first rod; when the sensor detects that the yarn is broken, the output end of the actuator retracts to release the restriction on the first rod.

[0022] By adopting the above technical solution, when the sensor detects that the yarn is broken, the output end of the actuator retracts and the restriction on the first rod is released. This action process is the key link to realize the function of self-stop when the yarn is broken. The action of the actuator can be realized by electrical control, hydraulic control or pneumatic control. When the sensor sends a broken signal, the control system will respond quickly and send a command to the actuator to retract the output end of the actuator. The retraction action of the actuator will cause the first rod to lose its restriction, so that the first rod and the second rod enter the open state under the action of the linkage mechanism, and the roller mechanism is separated from the rubber roller, and the clamping and drafting of the yarn are stopped.

[0023] A ring spinning device is characterized by comprising an end breakage automatic stop mechanism.

[0024] By adopting the above technical solution, the ring spinning device takes the end-breakage automatic stop mechanism as the core component, aiming to solve the common end-breakage problem in the traditional ring spinning process and improve production efficiency and yarn quality. The device realizes the clamping, drafting, spinning and other operations of the fiber through the synergistic effect of various components, and can respond quickly when the end-breakage occurs, automatically stop the operation of related mechanisms, and prevent the end-breakage from further deteriorating and causing damage to the equipment.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Quick response to yarn breakage: When the sensor detects yarn breakage, the actuator moves quickly, causing the first rod and the second rod to enter the open state under the action of the linkage mechanism, and the roller mechanism separates from the rubber roller, quickly stopping the clamping and drafting of the yarn to prevent the broken yarn from further winding around the roller, reducing the downtime caused by handling broken yarns, and improving the actual operating time and production efficiency of the equipment; 2. Stability of linkage mechanism: The design of the first link, the second link and the third link in the linkage mechanism enables the first rod and the second rod to rotate in opposite directions, thus achieving accurate coordination between the roller mechanism and the rubber roller. The driving spring provides the first rod and the second rod with a preload force that always keeps them open, ensuring a quick response in the event of abnormal situations such as broken ends, thus enhancing the reliability of the equipment.

[0026] 3. The speed regulating component can accurately adjust the speed of the roller according to different fiber characteristics and spinning process requirements. The adjustment unit synchronously drives the slide bar to move, changes the diameter of the pulley disk composed of the pulley block, and realizes the change of the transmission ratio with the input component, thereby continuously adjusting the speed of the roller to ensure the uniformity and stability of the fiber during the drafting process and improve the quality and uniformity of the yarn.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 7 This application is described in further detail.

[0029] The embodiments of the present application disclose a breakage automatic stop mechanism and a ring spinning device.

[0030] Example 1, reference Figure 1 and Figure 2 A head-breaking automatic stop mechanism comprises a machine body 1, a power assembly 2 connected to an external power source, a first rod 3 and a second rod 4 rotatably connected to the machine body 1, a plurality of rubber rollers 31 mounted on the first rod 3, a roller mechanism 6 mounted on the second rod 4, a linkage mechanism 5 connecting the first rod 3 and the second rod 4, and a locking mechanism 7 for limiting the rotation of the first rod 3, the machine body 1 is rotatably connected to a first mounting shaft 11 and a second mounting shaft 12, the end of the first rod 3 is rotatably connected to the first mounting shaft 11, the end of the second rod 4 is rotatably connected to the second mounting shaft 12, the first rod 3 rotates through the linkage mechanism 5 to drive the second rod 4 to rotate in the opposite direction; the positions of the first rod 3 and the second rod 4 have two extreme states, namely an open state and a closed state; refer to Figure 3 , closed state: the power input end of the roller mechanism 6 is connected to the power output end of the power assembly 2, the first rod 3 falls into the locking mechanism 7, and the movement of the first rod 3 is restricted by the locking mechanism 7; refer to Figure 4 , Open state: the roller mechanism 6 is abutted and separated from the rubber roller 31 , the power input end of the roller mechanism 6 is disengaged from the power output end of the power assembly 2 , and the first rod 3 is disengaged from the locking mechanism 7 .

[0031] When the first rod 3 and the second rod 4 are in a closed state under normal working conditions, the roller mechanism 6 abuts against the rubber roller 31, and the roller mechanism 6 and the rubber roller 31 work together to pull the yarn forward; when a spinning end break is detected, the locking mechanism 7 of the corresponding workstation releases the restriction of the first rod 3 of the workstation, and the first rod 3 and the second rod 4 open outwardly under the action of the linkage mechanism 5, which on the one hand disengages the roller mechanism 6 from the rubber roller 31, and on the other hand disengages the power input end of the roller mechanism 6 from the output end of the power assembly 2, thereby achieving self-stopping of a single workstation and reducing the impact on other workstations.

[0032] refer to Figure 5 The linkage mechanism 5 includes a first connecting rod 51 fixedly connected to the end of the first rod 3, a second connecting rod 52 fixedly connected to the end of the second rod 4, and a third connecting rod 53 rotatably connected to the body 1. The first connecting rod 51 is provided with a first groove 54, and the end of the second connecting rod 52 can move along the first groove 54. The third connecting rod 53 is provided with a second groove 55, and the end of the first connecting rod 51 can move along the second groove 55. In this embodiment, the angle formed by the first rod 3 and the first connecting rod 51 is an obtuse angle, and the angle formed by the second rod 4 and the second connecting rod 52 is an obtuse angle. The angle formed can also be an acute angle. The third connecting rod 53 is fixedly connected to the first block 58, and the third connecting rod 53 is fixedly connected to the first block 58. 53 is slidably connected with the second block 56, and a driving spring 57 is arranged between the first block 58 and the second block 56. The driving spring 57 forces the second block 56 to abut against the first connecting rod 51. When the first rod 3 and the second rod 4 are closed, the end of the first connecting rod 51 is located at one end of the second slot 55, and the spring 57 is compressed to store elastic force. When the broken end is detected, the restriction of the first rod 3 is released, and the spring 57 pushes the second block 56, so that the first connecting rod 51 moves to the other end of the second slot 55. The first connecting rod 51 also pushes the second connecting rod 52, so that the second rod 4 rotates in the opposite direction of the first rod 3, thereby realizing the opening of the first rod 3 and the second rod 4.

[0033] refer to Figure 6 The roller mechanism 6 includes a plurality of rollers 61 rotatably connected to the second rod 4, a plurality of speed regulating components 63 for regulating the rotation speed of the rollers 61, and an input component 62 capable of connecting to the output end of the power component 2; the input component 62 transmits power to different rollers 61 through different speed regulating components 63, and when the first rod 3 and the second rod 4 are in a closed state, the input component 62 connects to the power component 2. The second rod 4 is fixedly connected with a plurality of first seats, and the rollers 61 are arranged in the first seats. Since it is necessary to make different rollers 61 have speed differences during the ring spinning process, the rotation speed of the rollers 61 is adjusted by manually adjusting the corresponding speed regulating components 63. All rollers 61 are driven by a common input component 62, so that the synchronization of the rotation of the rollers 61 is achieved.

[0034] refer to Figure 6 The speed regulating assembly 63 includes a rotating frame 631 fixedly connected to the end of the roller 61, a sliding rod 634 slidably connected to the rotating frame 631, a pulley block 633 fixedly connected to the end of the sliding rod 634, and an adjusting unit 630 for driving the sliding rod 634 to move. The rotating frame 631 is provided with six sliding channels 632 arranged in an equiangular ring shape. The sliding rod 634 is arranged in the sliding channel 632. The adjusting unit 630 can synchronously drive all the sliding rods 634 to move. All the pulley blocks 633 are combined into a pulley disk 6330 with adjustable diameter. The pulley disk 6330 is connected to the input assembly 62 through a belt transmission. The change in the diameter of the pulley disk 6330 will cause the transmission ratio between it and the input assembly 62 to change. When the diameter of the pulley disk 6330 increases, the transmission ratio decreases, and the speed of the roller 61 decreases; when the diameter of the pulley disk 6330 decreases, the transmission ratio increases, and the speed of the roller 61 increases. In this way, the rotation speed of the roller 61 can be continuously adjusted to meet different spinning process requirements.

[0035] refer to Figure 6 The adjustment unit 630 includes a slider 6303, an intermediate rod 6305 rotatably connected to the pulley block 633, a hollow rod 6301 fixedly connected to the rotating frame 631, and a screw rod 6302 arranged inside the hollow rod 6301. The side of the hollow rod 6301 is provided with a plurality of through grooves 6306 connected to the interior. The slider 6303 is slidably connected to the inner wall of the hollow rod 6301. The slider 6303 is threadedly connected to the screw rod 6302. The slider 6303 is provided with a connecting portion 6304 that passes through the through groove 6306. The connecting portion 6304 is rotatably connected to the intermediate rod 6305, and the end of the screw rod 6302 passes through the end of the hollow rod 6301. When the screw rod 6302 rotates clockwise, the slider 6303 moves toward one end of the hollow rod 6301, and pulls the slide bar 634 outward through the middle rod 6305, so that the diameter of the pulley disc 6330 increases, thereby increasing the rotation speed of the roller roller 61; conversely, when the screw rod 6302 rotates counterclockwise, the slider 6303 moves toward the other end, pushing the slide bar 634 inward, the diameter of the pulley disc 6330 decreases, and the rotation speed of the roller roller 61 decreases. The synchronous adjustment mechanism enables each pulley block 633 of the pulley disc 6330 to change position simultaneously and evenly, ensuring the stability of the shape and transmission ratio of the pulley disc 6330. In the spinning process, this is very important to ensure the uniformity of fiber drafting and the stability of yarn quality. If the movement of each slide bar 634 is not synchronized, the pulley disc 6330 will be deformed, the tension of the transmission belt will be uneven, and the rotation speed of the roller roller 61 will fluctuate, affecting the spinning quality.

[0036] refer to Figure 6The input assembly 62 includes a rotating shaft 621 rotatably connected to the second rod 4, a plurality of driving pulleys are fixedly connected to the rotating shaft 621, the driving pulleys are connected to the pulley disc 6330 through a belt, and a worm gear 622 is provided at the rotating end. The second rod 4 is fixedly connected to the second seat, and the rotating shaft 621 is arranged in the second seat. The input assembly 62 serves as a connecting bridge between the external power and the internal actuator. In this way, the entire machine body 1 only needs to set up one power assembly 2, and the roller mechanism 6 can independently obtain power from the power assembly 2, so that each station does not interfere with each other, which is also convenient for realizing direct stop of a single station.

[0037] refer to Figure 6 The power assembly 2 includes a power shaft 21 connected to an external power source, a transmission shaft 22 installed on the body 1, and a worm 23 fixedly connected to the end of the transmission shaft 22. The transmission shaft 22 and the power shaft 21 are connected through a bevel gear transmission. When the first rod 3 and the second rod 4 are in a closed state, the worm 23 is meshed with the worm wheel 622; when a broken end is found, the worm 23 and the worm wheel 622 are disengaged. When the first rod 3 and the second rod 4 are in a closed state, the worm 23 is meshed with the worm wheel 622, and the rotation of the worm 23 transmits power to the worm wheel 622 through meshing. The rotation of the worm wheel 622 drives the rotating shaft 621 in the input assembly 62 to rotate, and then transmits the power to the pulley disc 6330 in the speed regulating assembly 63 through the driving pulley and belt, and finally drives the roller 61 to rotate. In this process, the power from the power source passes through the power shaft 21, the transmission shaft 22, the worm 23, the worm wheel 622, the rotating shaft 621, the driving pulley and the pulley disc 6330 in sequence, realizing the power input to the roller mechanism 6. When a yarn break is found, the worm 23 is disengaged from the worm wheel 622. This design is to realize the function of self-stopping when the yarn is broken. When the sensor 73 detects that the yarn is broken, the control system will respond quickly and disengage the worm 23 from the worm wheel 622 in some way, thereby cutting off the power transmission and stopping the roller mechanism 6.

[0038] refer to Figure 7 The locking mechanism 7 includes a sensor 73, a frame 72 fixedly connected to the machine body 1, and an actuator 71 installed in the frame 72. The sensor 73 is installed on the first rod 3 and the roller mechanism 6 respectively. When the first rod 3 and the second rod 4 are in a closed state, the first rod 3 falls into the frame 72, and the output end of the actuator 71 extends to abut the first rod 3; when the sensor 73 detects that the yarn is broken, the output end of the actuator 71 retracts to release the restriction on the first rod 3. The actuator 71 is installed on the first rod 3 and the roller mechanism 6 respectively, and its function is to detect whether the yarn is broken. In this embodiment, the sensor 73 adopts a photoelectric sensor 73, and the actuator 71 adopts an electromagnetic telescopic rod. When the electromagnetic telescopic rod is powered on, the output end retracts; when the power is off, the output end extends on the internal reset member.

[0039] When the first rod 3 and the second rod 4 are in a closed state, the first rod 3 falls into the frame 72, and the output end of the actuator 71 extends out to abut the first rod 3. At this time, the actuator 71 applies a certain pressure to the first rod 3 to keep the first rod 3 in a stable position, ensuring that the roller mechanism 6 and the rubber roller 31 can cooperate closely to clamp and stretch the fiber. When the sensor 73 detects that the yarn is broken, it will immediately send a signal to the control system. After receiving the signal, the control system quickly sends an instruction to the actuator 71 to retract the output end of the actuator 71 and release the restriction on the first rod 3. After the output end of the actuator 71 is retracted, the first rod 3 enters the open state together with the second rod 4 under the action of the linkage mechanism 5 and the driving spring 57. At this time, the roller mechanism 6 is separated from the rubber roller 31, the power input end of the roller mechanism 6 is separated from the power output end of the power assembly 2, and the roller roller 61 stops rotating, thereby preventing the broken yarn from further winding around the roller roller 61, reducing equipment failure and the impact on yarn quality.

[0040] The implementation principle of a self-stop mechanism for broken ends and a ring spinning device in an embodiment of the present application is as follows: the power source is connected to the power shaft 21 of the power assembly 2, and the power shaft 21 begins to prepare to receive and transmit power. The first rod 3 and the second rod 4 are in the initial position, at which time the first rod 3 and the second rod 4 are in a closed state. The power input end of the roller mechanism 6 and the power output end of the power assembly 2 are connected to the worm gear 622 through the worm 23. The first rod 3 falls into the frame 72 of the locking mechanism 7, and the output end of the actuator 71 extends out to abut the first rod 3, applying pressure to the first rod 3 to keep it in a stable position, ensuring that the roller mechanism 6 and the rubber roller 31 are tightly matched. The drive spring 57 in the linkage mechanism 5 is in a compressed state, and the end of the first connecting rod 51 is located at one end of the second groove 55.

[0041] The power source is started, and the power passes through the power shaft 21, the transmission shaft 22, the worm 23, the worm wheel 622, the rotating shaft 621 of the input assembly 62, and the belt in sequence, and finally transmits the power to the pulley disc 6330 in the speed regulating assembly 63. The speed regulating assembly 63 adjusts the speed according to the spinning process requirements. The screw rod 6302 in the regulating unit 630 rotates, driving the slider 6303 to move in the hollow rod 6301. When the screw rod 6302 rotates clockwise, the slider 6303 moves toward one end of the hollow rod 6301, and pulls the slide bar 634 outward through the intermediate rod 6305, so that the diameter of the pulley disc 6330 increases, thereby reducing the speed of the roller roller 61; conversely, when the screw rod 6302 rotates counterclockwise, the slider 6303 moves to the other end, pushing the slide bar 634 to move inward, the diameter of the pulley disc 6330 decreases, and the speed of the roller roller 61 increases. All the slide bars 634 move synchronously through the adjustment unit 630 to ensure the shape and transmission ratio stability of the pulley disc 6330, and to ensure the uniformity of fiber drafting and the stability of yarn quality. Under the action of power, the roller mechanism 6 clamps and drafts the fiber through rollers 61 with different speeds. The rollers 61 work together with the rubber roller 31 installed on the first rod 3 to pull the fiber forward and make it thinner.

[0042] The sensor 73 monitors the yarn status on the first rod 3 and the roller mechanism 6 in real time. When the yarn breaks, the sensor 73 detects changes in light or other related signals. The sensor 73 immediately sends a signal to the control system. After receiving the broken yarn signal, the control system quickly sends a command to the actuator 71. The actuator 71 responds to the command and its output end retracts. At this time, the restriction on the first rod 3 is released. The first rod 3 starts to move under the action of the linkage mechanism 5 and the driving spring 57. The driving spring 57 pushes the second block 56, so that the first connecting rod 51 moves to the other end of the second groove 55, and the first connecting rod 51 pushes the second connecting rod 52. Under the joint action of the first connecting rod 51 and the third connecting rod 53, the second rod 4 rotates in the opposite direction of the first rod 3 to achieve the opening of the first rod 3 and the second rod 4. As the first rod 3 and the second rod 4 are opened, on the one hand, the roller mechanism 6 is separated from the rubber roller 31, and the fiber is no longer clamped and stretched; on the other hand, the power input end of the roller mechanism 6 is disengaged from the output end of the power assembly 2, which is specifically manifested as the worm 23 and the worm wheel 622 are disengaged, the power transmission is cut off, and the roller 61 stops rotating. In this way, the self-stop of a single station is achieved, the impact on other stations is reduced, and the broken yarn is prevented from being further wound around the roller 61, reducing equipment failures and the impact on yarn quality.

[0043] The staff will handle the broken ends, clean up the broken yarns, check whether there are damaged or entangled yarns in the roller mechanism 6, rubber roller 31 and other components, and perform corresponding cleaning and repair. After the processing is completed, prepare to resume the operation of the equipment. At this time, manually push the first rod 3 and the second rod 4 back to the closed state, so that the first rod 3 falls back into the frame 72. The control system issues a command to extend the output end of the actuator 71 to abut the first rod 3, and restore the restriction on the first rod 3. At the same time, the control system controls the power assembly 2 to restart, and the power is transmitted again according to the normal working process. The roller mechanism 6 and the rubber roller 31 resume the clamping and drafting operations on the fibers, and the equipment continues to spin.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
