Description

Technical Field

[0001] The present invention relates to the technical field of spinning yarn guiding devices, and particularly to a yarn guiding device for spinning based on broken yarn detection. Background Art

[0002] When processing and producing spun yarn, whether it is for multi-strand yarn ply winding or supplying multi-strand yarn to subsequent textile machines for producing spun yarn products, corresponding yarn guiding devices need to be provided for guiding use;

[0003] Existing yarn guiding devices generally guide the yarn through elastic guide wheels, and tension sensors are arranged on their sides to detect and judge whether there is a broken yarn. The installation positions are relatively scattered, and subsequent maintenance and repair processing are relatively complex. Multiple points need to be checked for breakpoints. Moreover, the existing devices only detect broken yarns and do not effectively process them, resulting in situations such as yarn rewinding and slipping. Or, a driving member is used to control the corresponding detection device to clamp the yarn, which requires multiple sets of driving members to be used, resulting in high costs and energy consumption. For this reason, we propose a yarn guiding device for spinning based on broken yarn detection. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows:

[0016] 1. By setting a detection component and a guiding component, the present invention can perform centralized modular tension detection and automated broken yarn and break point detection and judgment operations on multiple groups of yarns. According to requirements, it can adapt to different numbers of yarns for yarn guiding operations. During yarn guiding, it can clean the yarns and perform broken yarn protection operations at different positions, avoiding the situations of yarn backtracking and slipping after yarn breakage. In addition, this device can be adapted to a variety of scenarios, such as yarn doubling, multi-line guiding to provide yarns for subsequent production, etc. It has strong adaptability and can be used for multiple purposes with one machine. Concentrating the yarn guiding on a single device also facilitates the subsequent maintenance and repair operations of the staff.

[0017] 2. By setting a detection component, the present invention can perform corresponding tension and broken yarn clamping control on multiple groups of yarns through internal components, and can perform operations such as tension detection and traction compensation on the yarns. Reducing the normal setting of driving motors can meet the modular control and processing of multiple groups of yarns, reducing the setting cost and energy consumption of the device.

[0018] 3. By setting a trigger block and its surrounding components, and pushing and pulling the cooperation block to be clamped or separated from the side of the cooperation rod through an electric push rod, the cooperation rod can drive the trigger blocks at different positions to rotate, enabling the yarns to be used modularly and gradually singly. In addition, the damping block provided can be elastically fixed to the inner cavity wall surface in a damped manner when the trigger block is not driven by the cooperation rod, so that it will not rotate by itself and affect the state change of subsequent component triggering.

[0019] 4. By setting a detection rod and its surrounding components, a pressure sensor is arranged on the lower side where the detection rod contacts the trigger block. When the yarn applies pressure to the locking rod, the force received by the pressure sensor changes, thereby detecting and judging the change in yarn tension. At the same time, when the pressure shows a cliff-like change, it can be judged that the yarn is broken. In addition, the movable rod can trigger the partition block to move away from each other to block the yarn at both sides of the locking rod.

[0020] 5. By setting a clamping frame and its surrounding components, when the partition block is not squeezed by the movable rod and resets, it can clamp and fix the yarn, thereby clamping the broken yarn to prevent it from backtracking and slipping. When the third motor drives the locking rod, under normal circumstances, it can compensate for the traction force received by the yarn. When the yarn is broken, it can drive the locking rod to wind up the yarn to prevent the excess yarn from running around randomly.

[0021] 6. By setting a guiding component, the present invention can constrain and guide multiple groups of yarns, and can move synchronously with the detection component. It can perform traction force detection on the yarns and be used in cooperation with the front-end detection component. It can perform side cleaning and broken yarn clamping assistance on the yarns to ensure the stable yarn guiding operation.

[0022] 7. The present invention detects the pressure on the second support cylinder by providing a detection block and its peripheral components. Under normal conditions, the force exerted on the yarn during traction can be detected and judged through the provided detection block. When the yarn breaks, the change in pressure on the second support cylinder is detected by the detection block. When the pressure value of the detection block does not change suddenly, it can be judged that the breakage reaches the front end of the movable frame. When the pressure value of the detection block suddenly changes, it can be judged that the breakage reaches the rear end of the movable frame, and corresponding yarn breakage handling is triggered accordingly.

[0023] 8. The present invention provides a first clamping plate, a second clamping plate and their peripheral components. Normally, the first clamping plate and the second clamping plate can guide the yarn to their central positions through the slots, and operations such as cleaning fluff on the side of the yarn can be carried out. In addition, when the yarn breaks, the first clamping plate and the second clamping plate are elastically supported to clamp the yarn, preventing the broken yarn from rewinding and slipping, and facilitating the subsequent yarn connection operation.

A connecting rod 13 is fixedly arranged between the second fixing frames 12. The connecting rod 13 is a circular rod. A detection assembly 2 for performing multiple groups of broken wire detection and tension control operations on the yarn is arranged between the first fixing frames 11. A guide assembly 3 for guiding and detecting the yarn is arranged on the side surface of the connecting rod 13;

[0037] Through the arranged detection assembly 2, the tension of multiple groups of yarns can be uniformly detected and controlled, and when a broken wire occurs, the broken wire can be processed in time;

[0038] As Figures 2 to 7As shown in the figure, the detection component 2 includes a reciprocating frame 21 movably arranged between the first fixing frames 11. The reciprocating frame 21 is a rectangular frame. A reciprocating screw rod 211 is movably arranged through the side of the reciprocating frame 21, and both ends of the reciprocating screw rod 211 penetrate through the first fixing frames 11. The reciprocating screw rod 211 is a cylindrical rod with thread grooves staggered on its side. Inside the reciprocating frame 21, a rotating block is movably installed inside the thread groove on the side of the reciprocating screw rod 211 and can be driven to reciprocate in cooperation with it. At one end of the reciprocating screw rod 211, a first motor 212 is fixedly installed, and the first motor 212 is fixedly arranged at the corresponding side position of the first fixing frame 11. At the position corresponding to the reciprocating screw rod 211 on the side of the reciprocating frame 21, a matching rod 22 is movably arranged through the side, and both ends of the matching rod 22 penetrate through the first fixing frames 11. The matching rod 22 is a cylindrical rod with a spline groove on its side. At one end of the matching rod 22, a second motor 221 is fixedly installed, and the second motor 221 is fixedly arranged at the corresponding side position of the first fixing frame 11. Inside the reciprocating frame 21, cavities 23 are equidistantly arranged at the position corresponding to the matching rod 22. The cavities 23 are circular cavities. Inside the cavities 23, a trigger block 231 is movably installed, and the trigger block 231 is movably sleeved on the side of the matching rod 22. The trigger block 231 is a rhombic ring block with different protruding heights on each side. At both sides of the trigger block 231, damping blocks 232 are fixedly installed, and the damping blocks 232 are attached to the wall surface of the cavity 23. The damping blocks 232 are ring blocks made of wear-resistant rubber material. Inside the trigger block 231, an installation groove 233 penetrating it is opened. The installation groove 233 is a convex-shaped groove. Inside the installation groove 233, an electric push rod 234 is fixedly arranged. At the output end of the electric push rod 234, a matching block 235 is fixedly installed, and the matching block 235 is clamped and attached to the side of the matching rod 22. The matching block 235 is a rectangular block with one side in a spline shape. Below the electric push rod 234, a storage battery 236 is arranged, and the storage battery 236 is movably arranged inside the installation groove 233. The electric push rod 234 and the storage battery 236 are electrically connected through an electric contact block; specifically, the storage battery 236 supplies power to the electric push rod 234. When the electric push rod 234 pushes the matching block 235 to be clamped on the side of the matching rod 22, the second motor 221 drives the matching rod 22 to rotate, which can drive the corresponding trigger block 231 to rotate accordingly. The trigger block 231 is used to trigger subsequent components. On the contrary, when the electric push rod 234 pulls the matching block 235 away from the side of the matching rod 22, the corresponding trigger block 231 can be made not to be driven. In this way, multiple triggering methods can be formed to cooperate with multiple yarn tension adjustments;

[0039] A connecting cavity 24 penetrating the reciprocating frame 21 is provided on the wall of the inner cavity 23, and the connecting cavity 24 is a cylindrical cavity with a cross-shaped cross section, and a detection rod 241 is movably installed inside the connecting cavity 24, and both ends of the detection rod 241 extend from the inside of the connecting cavity 24 to the side of the reciprocating frame 21 and the inside of the inner cavity 23, the detection rod 241 is a cylindrical rod with a cross-shaped cross section, and a pressure sensor is arranged on the lower side thereof (the sensor model that can detect tiny pressure can be used, and is not limited here), a first spring 242 is fixedly connected to the side of the detection rod 241 and the wall of the connecting cavity 24, and the first spring 242 is movably sleeved on the side of the detection rod 241, and the pressure sensor on the side of the trigger block 231 can be detected by the detection rod 241 pressure sensor, and an active cavity 243 penetrating it is provided on the side of the detection rod 241, and the active cavity 243 is a cylindrical cavity with a cross-shaped cross section. A movable rod 244 is installed, and the bottom part of the movable rod 244 extends out of the movable cavity 243. The movable rod 244 is a cylindrical rod with a cross-section in the shape of a Chinese character "土" and a tapered upper side. A second spring 245 is fixedly connected between the side of the movable rod 244 and the wall of the movable cavity 243, and the second spring 245 is movably sleeved on the side of the movable rod 244. Specifically, when the trigger block 231 is driven to rotate by the matching rod 22, the trigger block 231 can first squeeze the movable rod 244, so that the upper end of the movable rod 244 slides inside the movable cavity 243 and extends out of the movable cavity 243 to trigger subsequent components. Then the trigger block 231 continues to squeeze the detection rod 241 to slide out of the connecting cavity 24. The distance of the detection rod 241 sliding out of the connecting cavity 24 can be linearly controlled by the side of the trigger block 231, and the three protruding points on the side can keep the detection rod 241 sliding out of the connecting cavity 24 at different distances.

[0040] A card slot 25 is symmetrically provided on the upper side of the detection rod 241. The card slot 25 is a rectangular slot. A card frame 251 is installed in the card slot 25. The card frame 251 is a "C"-shaped frame. A locking rod 252 is movably provided on the side of the card frame 251, and both ends of the locking rod 252 pass through the card frame 251. The locking rod 252 is an I-shaped round rod with a thread on the side. A spacer block 253 is movably sleeved on the side of the locking rod 252 in a mirror-image manner, and the spacer block 253 is arranged on the inner side of the card frame 251. The spacer block 253 is a side The circular ring block with an inclined surface is fixedly connected with a first support cylinder 254 between the side of the spacer block 253 and the inner side of the bracket 251, and the first support cylinder 254 is movably sleeved on the side of the lock rod 252. The first support cylinder 254 is a cylinder made of elastic material with a continuous "W"-shaped cross section. A third motor 26 is arranged on the upper side of the detection rod 241 corresponding to the position of the bracket 251, and the third motor 26 is fixed to the upper side of the detection rod 241 through a connecting cylinder. The third motor 26 is a motor with a circular thread groove at the output end and The locking rod 252 is threadedly installed inside its circular thread groove; specifically, when the upper end of the movable rod 244 slides out of the movable cavity 243, the movable rod 244 can be squeezed between the spacer blocks 253, so that the spacer blocks 253 slide away from each other under the constraint of the locking rod 252, and the third motor 26 can drive the locking rod 252 to rotate and drive, and the yarn is set on the side of the locking rod 252 to pull the yarn; by the yarn being attached to the side of the locking rod 252, pressure can be applied to the detection rod 241, and the tension of the yarn can be detected by the change of the pressure applied to the pressure sensor on the lower side of the detection rod 241. When the pressure suddenly changes drastically, it can be automatically determined that the yarn is broken. At this time, the trigger block 231 is driven to rotate so that its nearest concave position rotates to the corresponding detection rod 241 position, and the movable rod 244 and the detection rod 241 are reset under the elastic force of the first spring 242 and the second spring 245, and the spacer block 253 is reset synchronously by the elastic force of the first support tube 254 to clamp and fix the yarn;

[0041] The guide assembly 3 can be used to guide multiple groups of yarns, and can perform auxiliary operations on the yarns during the guiding process, and cooperate with the subsequent processing after the yarns are broken, etc.

[0042] like Figure 1 and Figures 8 to 10As shown in the figure, the guiding component 3 includes a movable frame 31 movably sleeved on the side of the connecting rod 13. The movable frame 31 is a rectangular frame. A linkage rod 34 is fixedly installed between the bottom side of the movable frame 31 and the bottom side of the reciprocating frame 21. The linkage rod 34 is a "C"-shaped rod. Sliding grooves 32 are equidistantly formed on the side of the movable frame 31. The sliding grooves 32 are convex-shaped grooves. A slider 321 is movably installed inside the sliding grooves 32 and a part of the slider 321 extends out of the inside of the sliding grooves 32. The slider 321 is a convex-shaped block. A constraint rod 322 is fixedly installed on the wall surface of the sliding groove 32 and the constraint rod 322 penetrates through the slider 321. The constraint rod 322 is a cylindrical rod. A detection block 323 is fixedly installed on the wall surface of the sliding groove 32 away from the constraint rod 322. The detection block 323 is a pressure sensor (any sensor model that can detect minute pressure is acceptable, and no specific limitation is made here). A second support cylinder 324 is fixedly connected between the side of the detection block 323 and the side of the slider 321 and the second support cylinder 324 is movably sleeved on the side of the constraint rod 322. A third support cylinder 325 is fixedly connected between the side of the slider 321 and the wall surface of the sliding groove 32 and the third support cylinder 325 is movably sleeved on the side of the constraint rod 322. Specifically, through the provided linkage rod 34, the movable frame 31 can move synchronously when the reciprocating frame 21 reciprocates. Through the provided second support cylinder 324 and third support cylinder 325, elastic support can be provided for the slider 321, so that the slider 321 is constrained by the constraint rod 322 to slide inside the sliding groove 32, and elastic guidance is provided for subsequent components. Through the provided detection block 323, the pressure change on the side of the constraint rod 322 can be detected. Among them, under normal traction, the pressure value remains within a certain range. When the pressure value changes, it can be judged that the traction force has changed;

[0043] On the upper side of the slider 321, a movable plate 33 is fixedly installed. The movable plate 33 is a rectangular plate. On the upper side of the movable plate 33, a first clamping plate 331 and a second clamping plate 332 are respectively arranged in a mirror image manner. The first clamping plate 331 and the second clamping plate 332 are rotatably installed on the upper side of the movable plate 33 through a round shaft. The first clamping plate 331 and the second clamping plate 332 are "L"-shaped blocks and can be adapted and combined with each other. On the side surfaces of the first clamping plate 331 and the second clamping plate 332 close to each other, a through slot 333 is opened. The slot 333 is an arc-shaped slot. On the upper side of the movable plate 33, arc-shaped guiding slots 334 are opened in a mirror image manner corresponding to the positions of the first clamping plate 331 and the second clamping plate 332. The guiding slots 334 are arc-shaped slots. Inside the guiding slots 334, guiding blocks 335 are movably installed, and the guiding blocks 335 are respectively fixedly installed at the lower side positions corresponding to the first clamping plate 331 and the second clamping plate 332. The guiding blocks 335 are arc-shaped blocks. On the wall surface of the guiding slots 334, guiding rods 336 are fixedly installed, and the guiding rods 336 penetrate through the guiding blocks 335. The guiding rods 336 are arc-shaped round rods. A third spring 337 is fixedly connected between the side surface of the guiding block 335 and the wall surface of the guiding slot 334, and the third spring 337 is movably sleeved on the side surface of the guiding rod 336; specifically, the third spring 337 arranged can elastically support the guiding block 335. When the guiding block 335 slides inside the guiding slot 334, it is restricted and guided by the guiding rod 336. When in use, the yarn is threaded between the first clamping plate 331 and the second clamping plate 332. The yarn is restricted by the slot 333 to the position between the first clamping plate 331 and the second clamping plate 332. The first clamping plate 331 and the second clamping plate 332 cooperate to clean the side surface of the yarn. When the yarn breaks, under the elastic force of the third spring 337, the yarn is clamped and fixed by the first clamping plate 331 and the second clamping plate 332.

[0044] Working principle:

[0045] Normal use: First step, by default, the electric push rods 234 inside all the trigger blocks 231 push the clamping grooves 25 to be clamped on the side of the mating rod 22. The second motor 221 drives the mating rod 22 to rotate the trigger blocks 231 to respectively squeeze the movable rod 244 and the detection rod 241. The movable rod 244 squeezes the spacer block 253 to move away from each other on the side of the locking rod 252 to block the side of the yarn. The detection rod 241 slides out a certain distance inside the connection cavity 24.

[0046] Second step, after respectively attaching multiple groups of yarns to the side of the locking rod 252, then thread the yarns through the positions between the corresponding first clamping plate 331 and the second clamping plate 332 respectively, and be restricted by the slot 333 to the central position between the first clamping plate 331 and the second clamping plate 332, and then connect to the rear-end winding device or the textile machine.

[0047] In the third step, when the winding device or the textile machine pulls the yarn, the first motor 212 drives the reciprocating screw rod 211 to cooperate with the reciprocating frame 21 to make it reciprocate, and the synchronous movable frame 31 moves back and forth on the side of the connecting rod 13 under the linkage of the linkage rod 34, so as to perform the yarn guiding operation;

[0048] Yarn tension detection: When the yarn is attached to the side of the locking rod 252, the yarn exerts a certain pressure on the detection rod 241. The pressure of the lower side of the detection rod 241 on the trigger block 231 increases on the basis of a fixed value. By detecting the pressure change at this time, the change in the yarn tension can be determined;

[0049] Yarn tension control: by detecting the tension changes of the yarns on the side of each group of locking rods 252, the cooperating rod 22 drives the trigger block 231 to rotate to different protrusion positions, so that the detection rod 241 can be pushed to slide out different distances in the connecting cavity 24, so that the locking rod 252 can control the tension of the yarns in three support tensions: small, medium and large. When the tensions of multiple groups of yarns change inconsistently, the electric push rod 234 can push and pull the card slot 25 to engage or disengage from the side of the cooperating rod 22, so that the corresponding trigger block 231 is driven to rotate by the cooperating rod 22, so that the distance adjustment operation of the corresponding detection rod 241 sliding out of the connecting cavity 24 is completed, and the tension adjustment control of multiple groups of yarns is satisfied. When the trigger block 231 is not driven by the cooperating rod 22, it can be fixed to the inner wall of the inner cavity 23 by the damping block 232 to prevent it from rotating.

[0050] Yarn breakage detection: when the pressure on the side of the trigger block 231 changes drastically through the detection rod 241, it can be determined that the yarn is broken. When the synchronous yarn is pulled, the first clamping plate 331 and the second clamping plate 332 constrain the side cleaning of the yarn, and the movable plate 33 is pulled as a whole to deform the second supporting tube 324; wherein: the detection block 323 detects the pressure change on the side of the second supporting tube 324, and the magnitude of the traction force on the yarn can be determined, which can assist in determining the change in the magnitude of the yarn tension, and when the traction force is insufficient, the third motor 26 drives the locking rod 252 to rotate to compensate for the yarn traction; when the yarn breaks, the detection pressure of the detection block 323 immediately changes greatly, and it can be determined that the yarn breakage occurs at the rear end of the movable frame 31. At this time, the detection pressure of the detection block 323 still does not change greatly, and it can be determined that the yarn breakage occurs at the front end of the movable frame 31;

[0051] Yarn breakage at the front end of the movable frame 31: At this time, the corresponding trigger block 231 is triggered to switch and is driven by the mating rod 22. The mating rod 22 drives the trigger block 231 to rotate the nearest concave portion to the position of the corresponding detection rod 241. The detection rod 241 and the movable rod 244 can be driven to reset through the first spring 242 and the second spring 245. The spacer block 253 clamps and fixes the yarn under the elastic reset force of the first support cylinder 254. Synchronously, the third motor 26 drives the locking rod 252 to rotate to wind up the broken yarn, preventing the yarn from running around; when the locking rod 252 winds up the broken yarn, at this time, a pressure change occurs in the spacer block 253, which means that the broken yarn appears at the rear end of the movable frame 31. The first clamping plate 331 and the second clamping plate 332 clamp the yarn, and the system determines that the broken yarn detection is incorrect and stops driving the third motor 26; for the above, the subsequent staff only needs to unscrew the thread of the locking rod 252 from the side of the output end of the third motor 26, and then the clamping frame 251 can be pulled out of the card slot 25 and the yarn can be manually unwound for subsequent wiring operations;

[0052] Yarn breakage at the rear end of the movable frame 31: At this time, the yarn loses traction, and the broken yarn is clamped and fixed by the first clamping plate 331 and the second clamping plate 332. Similarly, the trigger spacer block 253 is reset to clamp and fix the yarn. For the above, the subsequent staff only needs to pull the yarn clamped by the first clamping plate 331 and the second clamping plate 332 for wiring operations;

[0053] Among them, by default, when a broken yarn appears in the device, the subsequent device shutdown operation can be triggered. When a broken yarn does not cause an impact, such as when multiple groups of yarns are guided to different devices, only the corresponding broken yarn is clamped and fixed, and the subsequent corresponding device is shut down. The device can still perform normal yarn guiding operations.

[0054] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
