Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a yarn winding device for textile equipment and its control method. Background Technology

[0002] Yarn winding is a crucial step in the textile production process, and the quality of winding directly affects the subsequent transportation and performance of the yarn. During yarn winding, the yarn needs to undergo processes such as tension adjustment and traverse guiding before being wound onto the winding rollers to form a package that is easy to transport and store.

[0003] In related technologies, there exists a yarn winding device that achieves tension control and winding operations of the yarn by setting up a tension component and a winding component. The tension component of this device includes a guide roller and an auxiliary roller. The auxiliary roller has an internal cavity containing a main motor, a drive rod, a mounting cylinder, and a mating block. During operation, the main motor drives the drive rod to rotate, causing the mounting cylinder to rotate to a corresponding angular position. This causes the mating block to block the connecting groove on the auxiliary roller to varying degrees, thereby switching the airflow. When the yarn breaks, the controller controls the main motor to drive the drive rod to rotate to the corresponding detection position, causing the corresponding connecting groove to be blocked by the mating block, disconnecting the air pressure supply, and allowing the constraint plate to reset under elastic force and clamp the yarn.

[0004] However, the above-mentioned device has the following shortcomings: On the one hand, its yarn breakage response depends on the mechanical action of the main motor driving the drive rod to rotate, which requires multiple steps such as motor start-up, drive rod rotation, installation cylinder rotation to the target angle, and mating block movement into place. The response chain is long and there is a significant action delay. During the delay, the broken yarn may have already become scattered or tangled. On the other hand, the air circuit switching of each station depends on the centralized control of the same main motor and installation cylinder. The installation cylinder needs to be rotated to a specific angle to realize the air circuit opening and closing of the corresponding station. It is impossible to independently and instantly control each station. When a yarn breaks at a certain station, the air circuit status of other stations will also be affected. Summary of the Invention

[0005] This application provides a yarn winding device for textile equipment and its control method to solve the problem of long response links for yarn breakage caused by the reliance on mechanical rotation for air circuit switching in the prior art.

[0006] This application provides a yarn winding device for textile equipment, including a frame and a winding mechanism and a tension mechanism disposed on the frame. The tension mechanism includes a support body and tension adjustment units. The support body has an inlet channel for connecting to a pressure medium source and a discharge channel for depressurization. Multiple tension adjustment units are spaced apart along the axial direction of the support body. Each tension adjustment unit includes: a mounting base fixed to the support body and having multiple guide cavities circumferentially arranged; and multiple movable members corresponding to the guide cavities, each slidably disposed within its corresponding guide cavity. The movable members and the inner walls of the guide cavities enclose and form mutually isolated first chambers. The movable component has a drive channel communicating with the second chamber. Multiple clamping assemblies are provided corresponding to the movable component. Each clamping assembly includes a first clamping member, a second clamping member, and a reset member. The first clamping member is fixed to the movable component, the second clamping member is slidably disposed in the drive channel, and the reset member is connected to the second clamping member to provide a spring force to the second clamping member that tends to move away from the first clamping member. An electromagnetic reversing valve is provided corresponding to the mounting base to control the switching of the supply channel and the discharge channel with each of the first chambers and each of the second chambers on the mounting base.

[0007] According to one embodiment of this application, the mounting base has a first common flow channel and a second common flow channel on its inner side. The first common flow channel communicates with each of the first chambers of the mounting base, and the second common flow channel communicates with each of the second chambers of the mounting base. Each mounting base is correspondingly provided with an electromagnetic reversing valve. The electromagnetic reversing valve has a first working interface, a second working interface, a third working interface, and a fourth working interface. The first working interface communicates with the supply channel, the second working interface communicates with the discharge channel, the third working interface communicates with the first common flow channel, and the fourth working interface communicates with the second common flow channel. The electromagnetic reversing valve has a first working position and a second working position. In the first working position, the first working interface communicates with the third working interface, and the second working interface communicates with the fourth working interface. In the second working position, the first working interface communicates with the fourth working interface, and the second working interface communicates with the third working interface.

[0008] According to one embodiment of this application, the first common flow channel and the second common flow channel are annular grooves extending circumferentially along the mounting base, and the annular grooves are jointly formed by the inner wall of the mounting base and the outer wall of the support.

[0009] According to one embodiment of this application, the support body includes an inner cylinder and an outer cylinder sleeved on the outside of the inner cylinder. The inner cavity of the inner cylinder forms the inlet channel, and the outer wall of the inner cylinder is provided with a groove. The inner wall of the groove and the inner wall of the outer cylinder form the outlet channel.

[0010] According to one embodiment of this application, the second clamping member includes: a clamping block, the first clamping member having a first clamping surface, and the clamping block having a second clamping surface opposite to the first clamping surface; a driving rod located on the side of the clamping block away from the first clamping member, one end of the driving rod being fixedly connected to the clamping block, and the other end being slidably inserted through the driving channel; a slip ring fixed to the end of the driving rod away from the clamping block, the slip ring being located inside the driving channel, and the peripheral wall of the slip ring being slidably sealed to the inner wall of the driving channel; the reset member includes a compression spring, the compression spring being sleeved on the driving rod, one end of the compression spring abutting against the slip ring, and the other end abutting against the inner wall of the driving channel.

[0011] According to one embodiment of this application, the first clamping surface and the second clamping surface are respectively provided with damping rollers for contacting the yarn, and the damping rollers are arranged radially along the support.

[0012] According to one embodiment of this application, the damping roller located on the first clamping surface and the damping roller located on the second clamping surface are offset; wherein, when the second clamping member is close to the first clamping member, the damping roller located on the first clamping surface clamps the yarn with the second clamping surface, and the damping roller located on the second clamping surface clamps the yarn with the first clamping surface.

[0013] According to one embodiment of this application, the damping roller includes: a rotating roller, the two ends of which are provided with rotating shafts for rotatably connecting with the first clamping member or the second clamping member; and an adjustable damper, corresponding to the rotating roller, the adjustable damper including a housing, a first friction plate, a second friction plate, and a manual adjustment component, the housing being fixed to the first clamping member or the second clamping member, the first friction plate being rotatably disposed within the housing and coaxially fixed with the rotating shaft, the second friction plate being slidably disposed within the housing along the axial direction of the rotating shaft and in contact with the first friction plate, and the manual adjustment component being disposed in the housing and connected to the second friction plate for adjusting the position of the second friction plate along the axial direction of the rotating shaft to adjust the rotational damping of the rotating roller.

[0014] According to one embodiment of this application, the manual adjustment assembly includes: a slider slidably disposed within the housing; an adjustment bolt disposed axially along the rotation axis and threadedly connected to the housing, one end of the adjustment bolt being located within the housing and rotatably connected to the slider, and the other end being located outside the housing; and an arc-shaped spring piece located on the side of the slider near the second friction plate, one end of the arc-shaped spring piece being fixedly connected to the slider, the other end abutting against the slider, and the middle portion of the arc-shaped spring piece abutting against the second friction plate.

[0015] This application also provides a control method for the yarn winding device of the textile equipment according to the above embodiments, including: S1: In the normal winding state, controlling each of the electromagnetic reversing valves to be in a first working position, each of the movable parts extending out and each of the second clamping parts moving away from the corresponding first clamping part; S2: When a yarn breakage is detected corresponding to any of the tension adjusting units, controlling the electromagnetic reversing valve corresponding to the tension adjusting unit to switch to a second working position, each of the movable parts in the tension adjusting unit retracting synchronously and each of the second clamping parts synchronously forming a clamping engagement with the corresponding first clamping part to clamp the broken yarn; S3: After the yarn breakage is handled, controlling the electromagnetic reversing valve to switch back to the first working position.

[0016] The yarn winding device and control method for textile equipment provided in this application, by setting up an electromagnetic reversing valve corresponding to the mounting base, controls the switching of the feed channel and discharge channel with the first chamber and the second chamber on the corresponding mounting base. The electromagnetic reversing valve replaces the mechanical rotation switching structure that relies on the main motor and drive rod in related technologies with the electronic control switching of the electromagnetic reversing valve. The mechanical rotation link in the yarn breakage response link is replaced by the direct action of the electromagnetic valve. It eliminates the need for multiple steps such as motor start-up, drive rod rotation, mounting cylinder rotation to the target angle, and mating block movement into place. This shortens the actuator response time, eliminates the time delay and action uncertainty caused by mechanical rotation action, and reduces the risk of yarn drifting or tangling during the response period.

[0017] Furthermore, when the electromagnetic reversing valve switches to the second working position, the supply channel directly connects the second chamber and the drive channel. The pressure medium actively pushes the second clamping member to overcome the elastic force of the reset member and move towards the first clamping member to form a clamping engagement. This replaces the method in related technologies where the elastic member is passively reset and clamped by disconnecting the air pressure supply. This achieves an improvement in the clamping action from passive elastic reset to active air pressure drive. The start of the clamping action occurs synchronously with the switching of the reversing valve. There is no need to wait for the air pressure to be completely released before the elastic member resets, further shortening the time from the occurrence of wire breakage to the completion of the clamping action.

[0018] In addition, each tension adjustment unit is equipped with an independent solenoid directional valve. Each solenoid directional valve controls the on / off switching of each first chamber and each second chamber on its corresponding mounting base. When the yarn corresponding to a tension adjustment unit breaks, it is only necessary to control the solenoid directional valve corresponding to that tension adjustment unit to complete the broken yarn clamping. The solenoid directional valves corresponding to other tension adjustment units remain unchanged in their current working position, realizing independent control of each tension adjustment unit. When a yarn breaks at one station, other stations are not affected and can continue to rewind normally, avoiding the impact of a single station's yarn breakage on the operation of the entire machine.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0040] The following is combined Figures 1-8 This application describes a yarn winding device for textile equipment according to an embodiment of the present application.

[0041] Combination Figures 1 to 5 In some embodiments, the yarn winding device of the textile equipment includes a frame 400 and a winding mechanism 500 and a tension mechanism disposed on the frame 400. The tension mechanism includes a support body 100 and tension adjusting units 200. The support body 100 is provided with an inlet channel 130 for connecting to a pressure medium source and an outlet channel 140 for depressurization. Multiple tension adjusting units 200 are spaced apart along the axial direction of the support body 100. Each tension adjusting unit 200 includes a mounting base 210, a movable part 220, a clamping assembly 230, and a solenoid reversing valve 240.

[0042] The mounting base 210 is fixed to the support body 100 and has multiple guide cavities 211 circumferentially arranged. Multiple movable members 220 are correspondingly provided within the guide cavities 211, and each can be slidably disposed within its respective guide cavity 211. The movable member 220 and the inner wall of the guide cavity 211 enclose a first chamber 2111 and a second chamber 2112 that are mutually isolated. The movable member 220 has a drive channel 221 communicating with the second chamber 2112.

[0043] Multiple clamping assemblies 230 are provided corresponding to the movable member 220. Each clamping assembly 230 includes a first clamping member 231, a second clamping member 232, and a reset member 233. The first clamping member 231 is fixed to the movable member 220, and the second clamping member 232 is slidably disposed in the drive channel 221. The reset member 233 is connected to the second clamping member 232 and is used to provide a spring force to the second clamping member 232 to tend to move away from the first clamping member 231.

[0044] The electromagnetic reversing valve 240 is correspondingly provided with the mounting base 210 and is used to control the on / off switching of the supply channel 130 and the discharge channel 140 with the first chamber 2111 and the second chamber 2112 on the corresponding mounting base 210.

[0045] Exemplarily, the frame 400 serves as the supporting foundation for the entire device, and the winding mechanism 500 is mounted on the frame 400 to complete the yarn winding operation. The frame 400 and the winding mechanism 500 are not improvements to this embodiment and will not be described in detail here. A tension mechanism can be correspondingly arranged with one or more winding mechanisms 500, which can provide tension to the yarn when the winding mechanism 500 winds the yarn, thereby improving the winding effect and efficiency.

[0046] The support body 100 is a hollow cylindrical structure extending axially, rotatably mounted on the frame 400, and rotates together with the winding mechanism 500 during operation. The support body 100 has mutually isolated feed channels 130 and discharge channels 140. One end of the feed channel 130 is connected to a stationary pressure medium source pipeline via a rotary sealing joint. This pressure medium source can be an air compressor, used to provide a pressurized gas medium to the device. The discharge channel 140 is used to discharge the pressure medium inside the chamber to the external environment for depressurization. Multiple tension adjustment units 200 are arranged at intervals along the axial direction of the support body 100, each tension adjustment unit 200 being used to independently control the tension adjustment and breakage clamping of a single yarn.

[0047] The mounting base 210 is fixedly sleeved on the outer periphery of the support body 100. The mounting base 210 and the support body 100 can be fixed by means such as riveting or welding, or they can be integrally formed. The guide cavity 211 extends along the radial direction of the mounting base 210, and its open end faces the outer periphery of the mounting base 210. The mounting base 210 has a plurality of guide cavities 211 in its circumferential direction. The guide cavities 211 are cylindrical or square channels used to accommodate and guide the sliding of the moving part 220.

[0048] The movable component 220 is a columnar structure and is slidably installed within the guide cavity 211. One end of the movable component 220 has a laterally protruding annular structure on its outer peripheral surface. The outer wall of this annular structure and the inner wall of the guide cavity 211 form a sliding seal fit through a sealing element, thereby dividing the internal space of the guide cavity 211 into a first chamber 2111 and a second chamber 2112 that are mutually isolated. The first chamber 2111 is located between the end of the movable component 220 facing the bottom wall of the guide cavity 211 and the bottom wall of the guide cavity 211. When a pressure medium enters the first chamber 2111, it pushes the movable component 220 to slide towards the opening end of the guide cavity 211, at which point the movable component 220 extends. The second chamber 2112 is located between the end of the movable component 220 facing the opening end of the guide cavity 211 and the opening end of the guide cavity 211. When a pressure medium enters the second chamber 2112, it pushes the movable component 220 to slide towards the bottom wall of the guide cavity 211, at which point the movable component 220 retracts. The movable part 220 has a drive channel 221 inside. One end of the drive channel 221 is connected to the second chamber 2112, and the other end extends to the side of the movable part 220 that is away from the first clamping part 231.

[0049] The first clamping member 231 in the clamping assembly 230 is fixedly installed at the end of the movable member 220 extending out of the guide cavity 211 and moves with the movable member 220. The second clamping member 232 is slidably disposed in the drive channel 221, and its portion opposite to the first clamping member 231 is the clamping end. The reset member 233 is connected to the second clamping member 232 and always applies an elastic force to the second clamping member 232 to keep it away from the first clamping member 231. Therefore, when no other external force is applied, the second clamping member 232 is held in a position away from the first clamping member 231, forming a gap between them for the yarn to pass through. The electromagnetic reversing valve 240 is mounted on the mounting base 210, and its valve body has a movable valve core. The position of the valve core is switched by the on and off of the electromagnet, thereby changing the communication relationship between the feed channel 130 and the discharge channel 140 and the first chamber 2111 and the second chamber 2112.

[0050] In normal winding mode, the electromagnetic reversing valve 240 is in the first working position, the feed channel 130 is connected to the first chamber 2111, and the pressure medium enters the first chamber 2111, pushing the movable member 220 out. At the same time, the second chamber 2112 is connected to the discharge channel 140 to release pressure, and the second clamping member 232 moves away from the first clamping member 231 under the action of the reset member 233, allowing the yarn to be freely wound through the clamping assembly 230. By adjusting the pressure of the pressure medium in the feed channel 130, the length of the movable member 220 extending out of the guide cavity 211 can be changed, thereby changing the wrap angle of the yarn when it passes around the movable member 220, achieving stepless adjustment of the yarn tension. When a yarn breakage is detected, the electromagnetic reversing valve 240 switches to the second working position, connecting the supply channel 130 to the second chamber 2112. Pressure medium enters the second chamber 2112, pushing the movable part 220 back. Simultaneously, pressure medium enters the drive channel 221, pushing the second clamping part 232 to overcome the elasticity of the reset part 233 and move towards the first clamping part 231, forming a clamping engagement to hold the broken yarn. Each tension adjustment unit 200 corresponds to an independent electromagnetic reversing valve 240, allowing for independent control without interference. Thus, the electrically controlled switching of the electromagnetic reversing valve 240 replaces the traditional mechanical rotation switching structure, replacing the mechanical rotation link in the yarn breakage response chain with the direct action of the electromagnetic valve. This eliminates the time delay and uncertainty caused by mechanical rotation, reducing the risk of yarn scattering or tangling during the response period.

[0051] Furthermore, the mechanical rotation control method is difficult to adapt to situations with tension and many clamping components, requires high installation accuracy, and is prone to false triggering. However, this embodiment solves this problem by using a separate control method with an electromagnetic reversing valve 240.

[0052] Furthermore, in this embodiment, when the electromagnetic reversing valve 240 switches to the second working position and the supply channel 130 connects with the second chamber 2112, the retraction of the movable member 220 and the movement of the second clamping member 232 against the elastic force of the reset member 233 toward the direction of the first clamping member 231 are almost simultaneous, which can clamp the broken wire more quickly.

[0053] In some embodiments, the mounting base 210 has a first common flow channel 212 and a second common flow channel 213 on its inner side. The first common flow channel 212 communicates with each of the first chambers 2111 of the mounting base 210, and the second common flow channel 213 communicates with each of the second chambers 2112 of the mounting base 210. Each mounting base 210 is provided with a corresponding electromagnetic reversing valve 240, which has a first working interface, a second working interface, a third working interface, and a fourth working interface. The first working interface communicates with the feed channel 130, the second working interface communicates with the discharge channel 140, the third working interface communicates with the first common flow channel 212, and the fourth working interface communicates with the second common flow channel 213. The electromagnetic reversing valve 240 has a first working position and a second working position. In the first working position, the first working interface communicates with the third working interface, and the second working interface communicates with the fourth working interface. In the second working position, the first working interface communicates with the fourth working interface, and the second working interface communicates with the third working interface.

[0054] For example, the groove on the inner side of the mounting base 210 and the outer peripheral wall of the support 100 form a first common flow channel 212 and a second common flow channel 213, both of which are annular channels extending circumferentially along the mounting base 210. The first common flow channel 212 is connected to all the first chambers 2111 on the mounting base 210 through their respective first branch vents, and the second common flow channel 213 is connected to all the second chambers 2112 on the mounting base 210 through their respective second branch vents.

[0055] The solenoid directional valve 240 is mounted on the mounting base 210, and its four working ports perform different functions. The first working port is connected to the supply channel 130 to introduce pressurized medium, the second working port is connected to the discharge channel 140 to discharge pressurized medium, the third working port is connected to the first common flow channel 212, and the fourth working port is connected to the second common flow channel 213. The valve core inside the solenoid directional valve 240 has a two-position structure, and is driven by an electromagnet to switch between the first and second working positions. For example, the solenoid directional valve 240 is a two-position four-way directional valve.

[0056] When the solenoid directional valve 240 is in the first working position, the flow channel inside the valve core connects the first working interface with the third working interface, and simultaneously connects the second working interface with the fourth working interface. The supply channel 130 is connected to the first common flow channel 212 through the first and third working interfaces, thereby supplying pressure medium to each of the first chambers 2111. At the same time, each of the second chambers 2112 is connected to the discharge channel 140 through the second common flow channel 213, the fourth working interface, and the second working interface for pressure relief.

[0057] When the solenoid directional valve 240 is in the second working position, the valve core moves to another position, connecting the first working interface with the fourth working interface, and simultaneously connecting the second working interface with the third working interface. The supply channel 130 is connected to the second common flow channel 213 through the first and fourth working interfaces, thereby supplying pressure medium to each of the second chambers 2112. At the same time, each of the first chambers 2111 is connected to the discharge channel 140 for pressure relief through the first common flow channel 212, the third working interface, and the second working interface. The synchronous operation of all moving parts 220 on the same mounting base 210 can be controlled simultaneously by a single solenoid directional valve 240, ensuring the consistency of the operation of each moving part 220 within the same tension regulating unit 200. This eliminates the need for a separate control valve for each moving part 220, simplifying the air circuit structure and control logic, and reducing manufacturing costs.

[0058] In some embodiments, the first common flow channel 212 and the second common flow channel 213 are annular grooves extending circumferentially along the mounting base 210, and the annular grooves are jointly formed by the inner wall of the mounting base 210 and the outer wall of the support 100.

[0059] For example, the inner wall of the mounting base 210 has two annular grooves extending circumferentially, one annular groove forming a first common flow channel 212 and the other annular groove forming a second common flow channel 213. When the mounting base 210 is fitted onto the outer periphery of the support body 100, a closed annular space is formed between the annular grooves on the inner wall of the mounting base 210 and the outer wall of the support body 100, and this annular space is used as the common flow channel.

[0060] Multiple sealing rings can be installed between the mounting base 210 and the support body 100. These sealing rings are arranged on both sides of the annular groove to prevent cross-contamination of pressure media between different flow channels and to prevent leakage of pressure media from the mating gap between the mounting base 210 and the support body 100. Each annular groove is connected to the corresponding chamber of each guide cavity 211 and the corresponding working interface of the solenoid directional valve 240 via a radially extending channel inside the mounting base 210. This annular groove structure ensures that fluid communication is maintained between the mounting base 210 and the support body 100 during rotation, and that all circumferentially distributed moving parts 220 receive a uniform supply of pressure media, guaranteeing the balanced force and synchronous movement of each moving part 220 on the same mounting base 210.

[0061] In some embodiments, the support 100 includes an inner cylinder 110 and an outer cylinder 120 sleeved on the outside of the inner cylinder 110. The inner cavity of the inner cylinder 110 forms a feed channel 130, and the outer wall of the inner cylinder 110 is provided with a groove. The inner wall of the groove and the inner wall of the outer cylinder 120 form a discharge channel 140.

[0062] For example, the support body 100 adopts a double-layer cylindrical structure. The inner cylinder 110 is a cylindrical member extending axially, and its interior is hollow to form a supply channel 130. The end of the inner cylinder 110 away from the frame 400 is sealed to ensure pressure supply. One end of the supply channel 130 is connected to a stationary pressure medium source pipeline through a rotary joint. The outer peripheral wall of the inner cylinder 110 is provided with a groove along the axial direction. This groove can be a straight groove extending axially or a spiral groove.

[0063] The outer cylinder 120 is a cylindrical component sleeved on the outside of the inner cylinder 110, with the inner wall of the outer cylinder 120 fitting against the outer wall of the inner cylinder 110. When the groove on the outer wall of the inner cylinder 110 is covered by the outer cylinder 120, the inner wall of the groove and the inner wall of the outer cylinder 120 together form an axially extending discharge channel 140. The electromagnetic reversing valve 240 can be installed on the outer cylinder 120 or the inner cylinder 110. The inlet channel 130, the outlet channel 140, the first common flow channel 212, and the second common flow channel 213 can all be connected to the corresponding working interface of the electromagnetic reversing valve 240 through through holes opened in the outer cylinder 120 and the inner cylinder 110 or external connecting pipes.

[0064] The pressure medium in the inlet channel 130 has a high pressure, while the pressure of the medium in the outlet channel 140 is close to atmospheric pressure. The two are isolated from each other by a sealed separation achieved by the walls of the inner cylinder 110 and the outer cylinder 120. This inner and outer casing structure allows the inlet channel 130 and the outlet channel 140 to be integrated inside the same support body 100, eliminating the need for separate piping outside the support body 100 and improving the overall structural compactness and reliability of the machine.

[0065] Combination Figure 6 In some embodiments, the second clamping member 232 includes a clamping block 2321, a drive rod 2322, and a slip ring 2323. The first clamping member 231 has a first clamping surface, and the clamping block 2321 has a second clamping surface opposite to the first clamping surface. The drive rod 2322 is located on the side of the clamping block 2321 opposite to the first clamping member 231. One end of the drive rod 2322 is fixedly connected to the clamping block 2321, and the other end is slidably inserted through the drive channel 221. The slip ring 2323 is fixed to the end of the drive rod 2322 opposite to the clamping block 2321. The slip ring 2323 is located inside the drive channel 221, and the peripheral wall of the slip ring 2323 slides and seals against the inner wall of the drive channel 221. The reset member 233 includes a compression spring, which is sleeved on the drive rod 2322. One end of the compression spring abuts against the slip ring 2323, and the other end abuts against the inner wall of the drive channel 221.

[0066] For example, the clamping block 2321 is the end structure of the second clamping member 232 facing the first clamping member 231, and its end face is the second clamping surface, which is used to cooperate with the first clamping surface of the first clamping member 231 to clamp the yarn. The first clamping surface and the second clamping surface can be planes, or they can be mutually cooperating arc-shaped surfaces or V-shaped surfaces to increase the contact area with the yarn and improve the clamping stability.

[0067] The drive rod 2322 is a long rod-shaped structure, with one end fixedly connected to the bottom side of the clamping block 2321 opposite to the first clamping member 231, and the other end extending axially along the drive channel 221 and penetrating into the drive channel 221. The slip ring 2323 is a circular ring-shaped structure, fixedly installed at the end of the drive rod 2322 that extends into the drive channel 221. The outer diameter of the slip ring 2323 matches the inner diameter of the drive channel 221. A sealing ring is embedded in the outer peripheral wall of the slip ring 2323, forming a sliding seal with the inner wall of the drive channel 221, dividing the drive channel 221 into a rod-type cavity located on the side of the slip ring 2323 closer to the clamping block 2321 and a rodless cavity located on the side of the slip ring 2323 away from the clamping block 2321. The rodless cavity communicates with the second chamber 2112. The rod-type cavity communicates with the external environment through a groove or gap formed between the inner wall of the drive channel 221 port and the drive rod 2322.

[0068] A compression spring is sleeved on the outside of the drive rod 2322, with one end abutting against the end face of the slip ring 2323 facing the clamping block 2321, and the other end abutting against the stepped surface of the inner wall of the drive channel 221 near the clamping block 2321. This stepped surface is a radially contracting structure of the inner wall of the drive channel 221, with its inner diameter being smaller than the outer diameter of the slip ring 2323 and larger than the outer diameter of the drive rod 2322, thereby forming an annular bearing surface inside the drive channel 221 for the end of the compression spring to abut against.

[0069] When the solenoid directional valve 240 is in the first working position, both the second chamber 2112 and the rodless chamber in the drive channel 221 are in a depressurized state. The elastic force of the compression spring pushes the slip ring 2323 to move the drive rod 2322 and the clamping block 2321 away from the first clamping member 231, causing the clamping block 2321 to retract and release the yarn. When the solenoid directional valve 240 switches to the second working position, the supply channel 130 introduces the pressure medium into the second chamber 2112. The pressure medium enters the rod chamber of the drive channel 221 through the second chamber 2112, pushing the slip ring 2323 to overcome the elastic force of the compression spring and move closer to the first clamping member 231. The slip ring 2323 drives the clamping block 2321 to extend synchronously through the drive rod 2322, so that the second clamping surface is close to the first clamping surface and clamps the yarn. The elastic force of the compression spring is opposite to the driving force of the pressure medium. The clamping force can be adjusted by adjusting the pressure of the pressure medium to meet the clamping requirements of different yarns.

[0070] Combination Figures 6 to 8 In some embodiments, the first clamping surface and the second clamping surface are respectively provided with damping rollers 300 for contacting the yarn, and the damping rollers 300 are arranged radially along the support 100.

[0071] For example, damping rollers 300 are respectively installed on the first clamping surface of the first clamping member 231 and the second clamping surface of the second clamping member 232. The damping roller 300 is a cylindrical roller, and its axial direction is arranged along the radial direction of the support body 100, that is, the axial direction of the damping roller 300 is consistent with the radial direction of the support body 100, and the yarn travel direction is tangent to the circumferential direction of the damping roller 300.

[0072] As the yarn passes between the first and second clamping surfaces, it contacts or separates from the circumferential surfaces of each damping roller 300. Under normal winding conditions, the yarn continues to travel, generating little or no friction with the damping rollers 300. The damping rollers 300 do not rotate with the movement of the yarn, resulting in almost no wear on the yarn surface.

[0073] In the broken yarn clamping state, the yarn is clamped between the damping roller 300 on the first clamping surface and the second clamping surface, and between the damping roller 300 on the second clamping surface and the first clamping surface. The damping roller 300 is in contact with the clamped yarn in the clamping state. When the yarn is pulled by other external forces, the yarn can drive the damping roller 300 to rotate, giving the yarn a certain amount of movement and preventing breakage due to concentrated tension under rigid clamping. Through its rotatable characteristic, the damping roller 300 converts the instantaneous impact tension of the yarn into the rotational motion of the damping roller 300, buffering the tension of the yarn and reducing the risk of the yarn breaking again due to excessive tension under clamping conditions.

[0074] In some embodiments, the damping roller 300 located on the first clamping surface and the damping roller 300 located on the second clamping surface are misaligned. When the second clamping member 232 approaches the first clamping member 231, the damping roller 300 located on the first clamping surface clamps the yarn with the second clamping surface, and the damping roller 300 located on the second clamping surface clamps the yarn with the first clamping surface.

[0075] For example, the damping rollers 300 on the first clamping surface and the damping rollers 300 on the second clamping surface are offset from each other in the yarn travel direction, that is, they are not aligned in the axial direction of the support 100. When the second clamping member 232 moves towards the first clamping member 231 under the drive of the pressure medium, the damping rollers 300 on the first clamping surface and the area on the second clamping surface where no damping rollers 300 are provided form a first clamping point, and at the same time, the damping rollers 300 on the second clamping surface and the area on the first clamping surface where no damping rollers 300 are provided form a second clamping point. The two clamping points are staggered along the yarn travel direction.

[0076] The yarn passes through the first and second clamping points sequentially, forming a curved path between them. In the staggered clamping state, the yarn successively bypasses the two staggered clamping points. When the yarn is under tension, the damping rollers 300 at each clamping point rotate, applying frictional damping to the yarn. The length of the curved section of the yarn between the two staggered damping rollers 300 changes with the yarn tension, further providing a buffer stroke for the yarn. This structure, combining staggered clamping with the rotation of the damping rollers 300, ensures that the yarn is reliably constrained while still possessing a certain degree of freedom of movement under clamping conditions, effectively preventing yarn breakage due to excessive tension.

[0077] In some embodiments, the damping roller 300 includes a rotating roller 310 and an adjustable damper 320. The rotating roller 310 has rotating shafts 311 at both ends for rotatably connecting to a first clamping member 231 or a second clamping member 232. The adjustable damper 320 is correspondingly disposed to the rotating roller 310 and includes a housing 321, a first friction plate 322, a second friction plate 323, and a manual adjustment assembly 324. The housing 321 is fixed to the first clamping member 231 or the second clamping member 232. The first friction plate 322 is rotatably disposed within the housing 321 and coaxially fixed with the rotating shaft 311. The second friction plate 323 is slidably disposed within the housing 321 along the axial direction of the rotating shaft 311 and contacts and engages with the first friction plate 322. The manual adjustment assembly 324 is disposed in the housing 321 and connected to the second friction plate 323, for adjusting the position of the second friction plate 323 along the axial direction of the rotating shaft 311 to adjust the rotational damping of the rotating roller 310.

[0078] For example, the rotating roller 310 is a cylindrical roller body, with rotating shafts 311 fixedly disposed at the center positions of its two ends. The rotating shafts 311 are mounted in bearings in the bearing seats disposed on the first clamping member 231 or the second clamping member 232, so that the rotating roller 310 can rotate freely around its own axis. An adjustable damper 320 is installed at one end of the rotating roller 310, and its housing 321 is fixed to the first clamping member 231 or the second clamping member 232, with a receiving cavity formed inside the housing 321.

[0079] The first friction plate 322 is a disc-shaped component, installed inside the housing 321 and fixedly connected to the rotating shaft 311, rotating together with the rotating shaft 311. The second friction plate 323 is a disc-shaped component corresponding to the first friction plate 322, its outer peripheral wall slidingly engaging with the inner wall of the housing 321, allowing it to slide axially along the rotating shaft 311, but its rotation around the rotating shaft 311 is restricted. The end face of the second friction plate 323 facing the first friction plate 322 and the end face of the first friction plate 322 facing the second friction plate 323 contact each other to form a friction mating surface. The manual adjustment component 324 is installed on the housing 321, and its output end is connected to the second friction plate 323.

[0080] The operator can manually adjust the adjustment component 324 to move the second friction plate 323 closer to or further away from the first friction plate 322 along the axial direction of the rotation shaft 311. When the second friction plate 323 is pushed against the first friction plate 322, the normal force between them increases, the friction increases, and the resistance experienced by the rotating roller 310 during rotation increases, i.e., the damping increases. Conversely, when the second friction plate 323 is pulled away from the first friction plate 322, the normal force decreases, the friction decreases, and the damping decreases. This achieves manual adjustment of the rotational damping of the rotating roller 310.

[0081] By adjusting the rotational damping, the rotational resistance of the damping roller 300 is matched to the breaking strength of the yarn. When the tension on the yarn is less than the set value, the damping roller 300 does not rotate or rotates slowly, keeping the yarn taut for easy handling. When the tension on the yarn approaches or exceeds the breaking strength, the yarn pulls the damping roller 300 to overcome the rotational resistance of the damper and rotate actively, releasing a section of yarn and reducing the tension to a safe range, thus preventing the yarn from breaking due to excessive tension while clamped. The rotational damping of the damping roller 300 can be pre-adjusted according to the breaking strength of different yarns to meet the protection needs of yarns of different specifications.

[0082] The adjustable damper 320 can be installed at only one end of the rotating roller 310, or one can be installed at each end of the rotating roller 310. When the adjustable damper 320 is installed at both ends of the rotating roller 310, the two dampers are adjusted synchronously to make the force at both ends of the rotating roller 310 balanced, so as to avoid the skew torque generated by the rotating roller 310 due to unilateral damping during rotation, and to ensure the uniformity of damping when the yarn passes through.

[0083] In some embodiments, the manual adjustment assembly 324 includes a slider 3241, an adjusting bolt 3242, and an arc-shaped spring piece 3243. The slider 3241 is slidably disposed within the housing 321. The adjusting bolt 3242 is axially disposed along the rotation shaft 311 and threadedly connected to the housing 321. One end of the adjusting bolt 3242 is located inside the housing 321 and rotatably connected to the slider 3241, while the other end is located outside the housing 321. The arc-shaped spring piece 3243 is located on the side of the slider 3241 near the second friction plate 323. One end of the arc-shaped spring piece 3243 is fixedly connected to the slider 3241, the other end abuts against the slider 3241, and the middle portion of the arc-shaped spring piece 3243 abuts against the second friction plate 323.

[0084] Exemplarily, a guide cavity 211 for a slider 3241 is formed inside the housing 321 on the side away from the first friction plate 322. The slider 3241 is installed in the guide cavity 211 and can slide freely along the axial direction of the rotation shaft 311. The adjusting bolt 3242 is a rod with external threads, and its axis is parallel to the axis of the rotation shaft 311. A threaded through hole is provided on the housing 321 to mate with the external threads of the adjusting bolt 3242, and the adjusting bolt 3242 passes through the threaded through hole. One end of the adjusting bolt 3242 extends into the housing 321 and is rotatably connected to the slider 3241 through a bearing or a limiting ring, so that when the adjusting bolt 3242 rotates, the slider 3241 only moves axially and does not rotate with the adjusting bolt 3242. The other end of the adjusting bolt 3242 extends out of the housing 321 and is provided with an operating handle or knob at the end for easy operation by hand.

[0085] The arc-shaped spring piece 3243 is an elastic metal sheet with an arc-shaped bend, its convex surface facing the second friction plate 323. One end of the arc-shaped spring piece 3243 is fixedly connected to the end face of the slider 3241 facing the second friction plate 323 by screws or welding, while the other end maintains sliding contact with the end face of the slider 3241, that is, this end can slide freely on the end face of the slider 3241. The protruding part in the middle of the arc-shaped spring piece 3243 abuts against the back of the second friction plate 323.

[0086] When the operator rotates the adjusting bolt 3242, the adjusting bolt 3242 moves axially under the action of the thread, pushing the slider 3241 to move closer to the second friction plate 323. The slider 3241 pushes the middle part of the arc-shaped spring 3243 to press against the second friction plate 323. The arc-shaped spring 3243 deforms under force, and the distance between its fixed end and the abutting end shortens. The abutting end slides on the end face of the slider 3241. The middle part of the arc-shaped spring 3243 transmits the pressure to the second friction plate 323, increasing the friction between the first friction plate 322 and the second friction plate 323, thereby increasing the damping.

[0087] When the adjusting bolt 3242 is rotated in the reverse direction, the slider 3241 retracts, reducing the pressure of the arc-shaped spring 3243 on the second friction plate 323 and decreasing the damping. When the second friction plate 323 is subjected to excessive reverse thrust, the arc-shaped spring 3243 can yield through its own elastic deformation, allowing the second friction plate 323 to retract a certain distance axially, preventing the friction between the first friction plate 322 and the second friction plate 323 from continuously increasing until it is completely locked. When the reverse thrust disappears, the arc-shaped spring 3243 returns to its original shape due to its own elasticity. The arc-shaped spring 3243 is always in a compressed state and continuously provides a basic thrust to the second friction plate 323, ensuring that the first friction plate 322 and the second friction plate 323 maintain contact and preventing damping failure due to poor contact.

[0088] One end of the arc-shaped spring 3243 is fixedly connected to the slider 3241, and the other end slides against the slider 3241. During the deformation of the arc-shaped spring 3243 under stress, the abutting end can slide freely along the surface of the slider 3241, so that the arc-shaped spring 3243 maintains a stable stress state during compression and recovery. Through its elastic deformation characteristics, the arc-shaped spring 3243 plays a buffering role in the damping adjustment process, avoiding a sudden increase in damping and yarn breakage due to complete locking caused by excessive tightening of the adjusting bolt 3242.

[0089] In some embodiments, the tension adjustment unit 200 further includes a return spring 250. Multiple return springs 250 are correspondingly provided with the movable member 220. Each return spring 250 is connected to a corresponding movable member 220 and provides a spring force to the movable member 220 toward the inside of the guide cavity 211. For example, the return spring 250 is a compression spring, with one end connected to the end of the movable member 220 located in the guide cavity 211, and the other end abutting against the stepped surface at the opening of the guide cavity 211. When the movable member 220 extends outward, the return spring 250 is compressed. The return spring 250 facilitates the balancing of the fluid pressure in the supply channel 130, allowing for flexible adjustment of the extension amount of the movable member 220 as needed; it also reduces the difficulty of retracting the movable member 220, improving operational stability.

[0090] The following describes a control method for a yarn winding device in textile equipment provided in an embodiment of this application. This method is executed by a controller located in a control cabinet. The controller is a programmable logic controller (PLC) and is electrically connected to the electromagnets of each solenoid directional valve 240 and tension sensors located along the yarn path. (In conjunction with...) Figure 9 The method includes steps S1 to S3.

[0091] S1: In the normal winding state, control each electromagnetic reversing valve 240 to be in the first working position, each movable part 220 extends out and each second clamping part 232 moves away from the corresponding first clamping part 231.

[0092] For example, under normal winding operation, all tension adjustment units 200 on the frame 400 are in operation, each independently controlling its corresponding yarn. The control system sends control signals to the electromagnets of each solenoid directional valve 240, so that the valve cores of all solenoid directional valves 240 are in the first working position.

[0093] In this working position, the feed channel 130 is connected to the first common flow channel 212 on each mounting base 210 through the flow channel inside the electromagnetic reversing valve 240. The pressure medium enters each first chamber 2111 through the feed channel 130 and the first common flow channel 212, pushing each movable part 220 to overcome the back pressure in the second chamber 2112 and extend along the guide cavity 211 in a direction away from the center of the mounting base 210 to a predetermined position.

[0094] Simultaneously, each second chamber 2112 is connected to the discharge channel 140 through the second common flow channel 213, the fourth working interface of the electromagnetic reversing valve 240, and the second working interface, to achieve pressure relief. Since the second chamber 2112 is connected to the drive channel 221, the drive channel 221 is also in a depressurized state. Each second clamping member 232 is held in a retracted position away from the first clamping member 231 by the elastic force of the reset member 233. At this time, each clamping assembly 230 is in the open state, and the yarn can freely pass through the gap between the first clamping member 231 and the second clamping member 232, entering the winding mechanism 500 to complete the winding operation. The position of the extended movable member 220 determines the yarn tension; the extension amount of the movable member 220 can be adjusted by controlling the pressure of the pressure medium, thereby adjusting the yarn tension.

[0095] S2: When a yarn breakage is detected corresponding to any tension adjustment unit 200, the electromagnetic reversing valve 240 corresponding to the tension adjustment unit 200 is switched to the second working position. The moving parts 220 in the tension adjustment unit 200 retract synchronously, and the second clamping parts 232 synchronously form a clamping engagement with the corresponding first clamping parts 231 to clamp the broken yarn.

[0096] For example, during the winding process, tension sensors installed on the yarn path continuously monitor the yarn tension. When a yarn breaks, the tension of that yarn disappears instantly, and the corresponding sensor detects the tension change signal and sends the detection signal to the controller. It can be understood that the tension sensor tests the pressure at the winding mechanism 500 or between the winding mechanism 500 and the tension mechanism.

[0097] The controller identifies the broken tension regulating unit 200 based on the received signal and sends a switching command to the corresponding solenoid directional valve 240. The valve core of the solenoid directional valve 240 moves to the second working position under the action of electromagnetic force. At the same time, the solenoid directional valves 240 corresponding to other tension regulating units 200 that have not broken remain in the first working position and continue to work normally.

[0098] In the tension adjustment unit 200 where a wire breakage occurs, the feed channel 130 in the second working position is connected to the second common flow channel 213 through the internal flow channel of the electromagnetic reversing valve 240. The pressure medium simultaneously enters all the second chambers 2112 on the mounting base 210 via the feed channel 130 and the second common flow channel 213. After the pressure medium enters each second chamber 2112, on the one hand, it pushes each movable part 220 to overcome the resistance of the first chamber 2111 and slide back along the guide cavity 211 towards the center of the mounting base 210. On the other hand, since each drive channel 221 is connected to the corresponding second chamber 2112, the pressure medium simultaneously enters each drive channel 221, pushing each second clamping part 232 to overcome the elastic force of the reset part 233 and move towards the first clamping part 231.

[0099] The retraction of movable part 220 causes the first clamping part 231 to move closer to the second clamping part 232, while the second clamping part 232 extends closer to the first clamping part 231, bringing the first clamping part 231 and the second clamping part 232 closer together and clamping the broken yarn between them. All movable parts 220 on the same mounting base 210 share the same pressure medium source through the first common flow channel 212 and the second common flow channel 213. The second chamber 2112 of each movable part 220 receives the pressure medium simultaneously, and each drive channel 221 receives the pressure medium simultaneously. In engineering terms, each movable part 220 can be regarded as retracting synchronously, and each second clamping part 232 moves synchronously, ensuring the consistency of the movement of each clamping component 230 within the same tension adjustment unit 200.

[0100] S3: After the wire breakage is resolved, control the solenoid directional valve 240 to switch back to the first working position.

[0101] For example, when the yarn breaks, the operator reconnects the broken yarn or replaces it with a new yarn. During the process, the electromagnetic reversing valve 240 of the tension adjustment unit 200 remains in the second working position, and each clamping component 230 continuously clamps the broken yarn end to prevent the yarn from flying around or getting caught in other mechanisms.

[0102] After the operator completes the yarn breakage repair and re-threads the yarn, the operator issues a recovery command via the control button. The controller sends a switching signal to the solenoid directional valve 240, and the valve core of the solenoid directional valve 240 switches back to the first working position. The feed channel 130 reconnects with the first common flow channel 212, and the pressure medium enters each of the first chambers 2111, pushing each movable part 220 to extend and reset. At the same time, each of the second chambers 2112 and the drive channel 221 is depressurized, and each of the second clamping parts 232 is moved away from the corresponding first clamping part 231 and resets under the action of the reset part 233. The clamping assembly 230 opens, the yarn returns to a free-flowing state, and the tension adjustment unit 200 can then resume normal winding operations.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
