Description

Technical Field

[0001] This invention relates to the field of cashmere fabric self-sewage technology, specifically to a cashmere fabric self-sewage mechanism with a breakage detection function and its splicing method. Background Technology

[0002] Cashmere fabric is formed by interlacing warp and weft yarns according to a certain pattern. The warp yarns are unwound from the warp beam, pass through the heald frame and reed, and form a "shed" through the up-and-down movement of the heald frame. The weft yarns are introduced by the weft introducer and then tightened by the reed. This cycle is repeated to form the fabric. Yarn breakage often occurs during the warp feeding process. The main reasons for breakage may be poor raw material quality, short fiber length resulting in low overall yarn strength, which cannot withstand weaving tension, or defects in the spinning process that cause the yarn to be too fine or have insufficient twist in some areas, forming a strong-weak loop that is easy to break under tension. It may also be due to improper tension adjustment of the equipment, which leads to yarn breakage. After the yarn breaks, it will form longitudinal strip-shaped defects on the fabric surface, namely "warp breakage" defects, which affect the smoothness and hand feel of the cashmere fabric. Multiple defects will affect the overall elasticity and quality of the fabric. Existing textile equipment can detect yarn breakage using infrared vision technology. High-speed industrial cameras and image processing algorithms are used to analyze yarn images in real time, accurately identifying breakage or entanglement anomalies. Then, a machine operator manually locates the break and uses tools such as warp hooks to knot and connect the broken warp yarn to the newly introduced yarn. However, manual knotting is slow, requiring the selection of the break point from numerous yarns, resulting in prolonged downtime and losses. Furthermore, the strength and tightness of manual knotting vary from person to person, leading to inconsistent joint thickness and strength. Some joints may be too thick, forming thick knots, or too loose, causing them to unravel again during subsequent weaving. Joints can also easily form noticeable protrusions on the cashmere fabric surface, affecting the fabric's feel and appearance. Therefore, we propose a self-splicing mechanism and method for cashmere fabric breaks with a breakage detection function. Summary of the Invention

[0003] The purpose of this invention is to provide a self-splitting mechanism and splicing method for cashmere fabric with a breakage detection function, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-splitting mechanism for cashmere fabric with yarn breakage detection function, comprising a frame, a warp feed roller on the frame, a first cylinder fixedly mounted on one side of the frame, and a motor slidably mounted on the other side, the output end of the first cylinder being rotatably connected to one end of the warp feed roller, and the output end of the motor being fixedly connected to the other end of the warp feed roller, a lower limit roller and an upper limit roller for limiting the yarn being rotatably mounted inside the frame, a second cylinder being fixedly mounted on the inner walls of both sides of the frame, a support rod being fixedly connected between the output ends of the two second cylinders, a plurality of top thread rings for applying tension to the yarn being sleeved on the support rod, and an infrared yarn breakage detection device for detecting yarn breakage being fixedly mounted on the frame; Two first slide rails are fixedly installed inside the frame. A first electric slide block is slidably installed on each first slide rail. A clamping plate is fixedly installed on each first electric slide block. A magnetic shaft is slidably installed on each clamping plate. A pulley is rotatably installed on each magnetic shaft. The two magnetic shafts are arranged in a magnetically repulsive manner. Magnetic blocks for generating magnetic attraction force on the magnetic shafts are symmetrically fixedly installed on the inner walls of both sides of the frame. A turntable is rotatably installed on each clamping plate. A rotating roller that cooperates with the pulley is rotatably installed on each turntable. A slot for limiting the magnetic shaft is provided on each turntable. A first electric push rod for pushing the turntable is fixedly installed on each first electric slide block. An air splicer for splicing yarn breaks is provided below one of the clamping plates.

[0005] Preferably, a gear is fixedly installed on one side of each turntable, a baffle for limiting the gear is fixedly installed at the output end of each first electric push rod, and a rack that meshes with the gear is fixedly installed on each baffle.

[0006] Preferably, each rack has an electric rotating shaft rotatably mounted at one end, and each electric rotating shaft has an infrared sensor plate for detecting wire ends fixedly mounted on it. Each infrared sensor plate is located below the corresponding rotating roller.

[0007] Preferably, each of the clamps is slidably mounted with a hanging plate, each hanging plate is made of magnetic material, and each of its sides is fixedly mounted with a stop bar limited by the turntable by two elastic rods. The air splicer is fixedly connected to the lower end of one of the hanging plates, and the lower end of the other hanging plate is fixedly mounted with a plug rod. The air splicer is provided with a plug hole that cooperates with the plug rod.

[0008] Preferably, two second slide rails are fixedly installed on the frame, a second electric slide block is slidably installed on each second slide rail, a second electric push rod is fixedly installed on each second electric slide block, and a combing rake for combing yarn is vertically slidably installed at the end of each second electric push rod.

[0009] Preferably, each of the combing rakes has a telescopic magnetic rod fixedly installed at both ends, and two limiting plates are symmetrically fixedly installed between the two second electric slides. Each limiting plate has two guide grooves symmetrically arranged for limiting the telescopic magnetic rod. Each guide groove is trapezoidal, and a magnetic plate that repels the magnetic force of the telescopic magnetic rod is fixedly installed on its bottom inner wall.

[0010] Preferably, two pressure plates for fixing the yarn are slidably installed inside the frame, and connecting ropes are rotatably installed at both ends of the warp feed roller. A second spring is fixedly connected to one end of each connecting rope and the inner wall of the frame. Several guide rollers for limiting the connecting ropes are rotatably installed on the inner walls on both sides of the frame, and each pressure plate is fixedly connected to two connecting ropes at both ends.

[0011] Preferably, the support rod is semi-circular in shape, and a plurality of pressure sensing plates are fixedly installed at its lower end. Each pressure sensing plate corresponds to a top wire ring. A first spring is fixedly installed at the lower end of each pressure sensing plate, and an arc-shaped plate is fixedly installed at the lower end of each first spring. Each arc-shaped plate is rotatably connected to the inner wall of the corresponding top wire ring.

[0012] Preferably, each of the top thread rings is fixedly installed on both sides with a limiting ring to prevent the yarn from running off-center.

[0013] A method for splicing cashmere fabric with a self-splitting mechanism for detecting fabric breakage includes the following steps: S1. Pass the yarn on the warp roller through the upper end of the lower limit roller and the lower end of the upper limit roller in sequence, and feed it into the subsequent cashmere fabric weaving mechanism. S2. Control the second cylinder to push the support rod and the top thread ring upward, and distribute the yarn evenly to each top thread ring. The top thread ring lifts the yarn, and the pressure sensed by the pressure sensor plate represents the tension of the yarn. S3. When the infrared yarn breakage detection device detects a yarn breakage and the corresponding pressure sensing plate also changes pressure, the first cylinder will push the warp roller upward to loosen the yarn completely, the motor will stop working and the yarn will stop moving. The second cylinder will retract to stop the top thread ring from applying pressure to the yarn. At the same time, the connecting rope will drive the two pressure plates to move, so that the yarn length in the area between the lower limit roller and the upper limit roller is fixed. S4. The two second electric slide blocks slide synchronously on the corresponding second slide rails to the pressure sensing plate where the pressure changes. Then the two second electric push rods extend synchronously, driving the two combing rakes to move relative to each other, so that the combing rakes comb the yarn and the broken ends of the yarn hang down. S5. The two first electric slide blocks slide synchronously on the corresponding first slide rails to the pressure sensing plate where the pressure changes. The two ends of the broken yarn hang down between the two clamping plates. The two magnetic shafts are driven by magnetic repulsion to drive the two pulleys to move in opposite directions. The two sets of pulleys and rollers clamp the two ends of the broken yarn respectively. Then, the two first electric push rods extend, causing the turntable to drive the pulleys and rollers to rotate 90 degrees. Then, the turntable, rollers and pulleys are pushed to move synchronously. After straightening the two ends of the broken yarn, the broken ends of the yarn move upward continuously. When the broken ends of the yarn contact the infrared sensing plate, the first electric push rod on that side will stop extending until the two broken ends of the yarn are found. S6. The two stop bars will be limited by the two turntables, causing the two hanging plates and the air splicer to move to the middle position of the two turntables. Then, the two electric rotating shafts drive the two infrared sensor plates to rotate, no longer supporting the two broken ends of the yarn. The two broken ends of the yarn will fall into the air splicer for splicing.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a top ring to lift the yarn and a pressure sensing plate to re-inspect the yarn breakage. When the yarn breaks, the first cylinder will send a roller to lift it, causing the yarn in the area between the lower limit roller and the upper limit roller to relax. Then, the first electric slide will slide synchronously on the first slide rail to the pressure sensing plate where the pressure changes. The two clamping plates move relative to each other, and both ends of the broken yarn will be located between the two clamping plates. As the first electric push rod extends, the two sets of pulleys and rotating rollers will clamp and straighten the broken ends of the yarn respectively. At the same time, the infrared sensing plate detects the yarn breakage point. Finally, the air splicer is used to automatically splice the two ends of the yarn. 2. This invention utilizes a second electric push rod to drive the combing rake. During the initial movement of the combing rake, gravity causes the telescopic magnetic rod to move along the inclined groove of the guide groove, and the combing rake gradually inserts into the yarn. Then, the telescopic magnetic rod moves along the horizontal groove at the bottom of the guide groove to comb the yarn, making it easier for the yarn ends to hang down. After the second electric push rod extends completely, the telescopic magnetic rod moves to the bottom end of the guide groove and moves upward under the magnetic repulsion of the magnetic plate, causing the combing rake to be pulled out of the yarn. Then, the second electric push rod drives the combing rake to retract. During the retraction process of the combing rake, it no longer combs the yarn, preventing excessive pulling on the yarn.

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

[0018] Please see Figure 1-10This invention provides a technical solution: a self-splitting mechanism for cashmere fabric with a yarn breakage detection function, comprising a frame 1, a warp feed roller 2 mounted on the frame 1, a first cylinder 3 fixedly mounted on one side of the frame 1, and a motor 4 slidably mounted on the other side. The output end of the first cylinder 3 is rotatably connected to one end of the warp feed roller 2, and the output end of the motor 4 is fixedly connected to the other end of the warp feed roller 2. A lower limit roller 5 and an upper limit roller 6 for limiting the yarn are rotatably mounted inside the frame 1. Two pressure plates 44 for fixing the yarn are slidably mounted inside the frame 1. Connecting ropes 45 are rotatably mounted at both ends of the warp feed roller 2. A second spring 46 is fixedly connected at one end of each connecting rope 45 to the inner wall of the frame 1. Several guide rollers 47 for limiting the connecting ropes 45 are rotatably mounted on the inner walls on both sides of the frame 1. Each pressure plate 44 is fixedly connected at both ends to two connecting ropes 45 respectively. When no yarn breaks, the mechanism detects the yarn breakage. When a yarn breakage occurs, the first cylinder 3 is in a retracted state and will not pull the connecting rope 45. When a yarn breakage occurs, the motor 4 will stop working, so that the warp roller 2 will no longer release the yarn. At the same time, the first cylinder 3 will extend and push the warp roller 2 upward, so that the yarn is completely relaxed. This prevents the yarn from being moved under tension after breaking and making it difficult to capture the broken yarn. After the warp roller 2 moves upward, it pushes a part of the yarn into the area between the lower limit roller 5 and the upper limit roller 6, which is convenient for capturing the broken yarn and splicing. At the same time, the warp roller 2 will pull one end of the connecting rope 45, so that the second spring 46 is stretched. The connecting rope 45 will drive the two pressure plates 44 to move, so that the two pressure plates 44 are respectively attached to the upper end of the lower limit roller 5 and the lower end of the upper limit roller 6, so that the yarn length in the area between the lower limit roller 5 and the upper limit roller 6 is fixed, preventing the yarn from slipping and making it difficult to capture when splicing the yarn later.

[0019] A second cylinder 7 is fixedly installed on the inner walls of both sides of the frame 1. A support rod 8 is fixedly connected between the output ends of the two second cylinders 7. Several top thread rings 9 for applying tension to the yarn are sleeved on the support rod 8. An infrared yarn breakage detection device 14 for detecting yarn breakage is fixedly installed on the frame 1 (the infrared yarn breakage detection device is a known existing structure, so it will not be described in detail in this invention). The support rod 8 is semi-circular, and several pressure sensing plates 10 are fixedly installed at its lower end. Each pressure sensing plate 10 corresponds to one of the top thread rings 9. Each pressure sensing plate 10 has a first spring 11 fixedly installed at its lower end, and an arc-shaped plate 12 fixedly installed at its lower end. Each arc-shaped plate 12 is rotatably connected to the inner wall of the corresponding top thread ring 9. Each top thread ring 9 has a limiting ring 13 fixedly installed on both sides to prevent yarn deviation. After the yarn moves to the area between the lower limiting roller 5 and the upper limiting roller 6, the second cylinder 7 pushes the support rod 8 and the top thread ring 9 upward. After the top thread ring 9 contacts the yarn, it lifts the yarn and stretches the first spring 11, distributing the yarn evenly. On each top thread ring 9, the tension on each first spring 11 is the same. The pressure sensed by the pressure sensing plate 10 represents the tension on the yarn. At the same time, the limiting ring 13 can prevent the yarn from shifting to adjacent top thread rings 9. After the yarn is subjected to the tension applied by the top thread ring 9, its movement angle and stretch change, causing the yarn to be prone to breakage in the area between the lower limiting roller 5 and the upper limiting roller 6. When the yarn does not break and moves normally, the top thread ring 9 will drive the limiting ring 13 to perform circumferential motion, while the pressure sensing plate 10 senses... The pressure should not change. When the infrared yarn breakage detection device 14 detects a yarn breakage and the corresponding pressure sensing plate 10 also shows a pressure change, it indicates that a yarn breakage has occurred on the corresponding top thread ring 9. The yarn breakage is re-inspected by the pressure change of the pressure sensing plate 10, which improves the accuracy of yarn breakage monitoring. At this time, the first cylinder 3 will be extended and the motor 4 will stop working, so that the yarn stops moving, which is convenient for subsequent yarn splicing. The second cylinder 7 will retract, so that the top thread ring 9 no longer applies pressure to the yarn.

[0020] Two second slide rails 36 are fixedly installed on the frame 1. A second electric slide block 37 is slidably installed on each second slide rail 36. A second electric push rod 38 is fixedly installed on each second electric slide block 37. A combing rake 39 for combing yarn is vertically slidably installed at the end of each second electric push rod 38. Telescopic magnetic rods 40 are fixedly installed at both ends of each combing rake 39. Two limiting plates 41 are symmetrically fixedly installed between the two second electric slide blocks 37. Each limiting plate 41 has two guide grooves 42 symmetrically arranged to limit the telescopic magnetic rods 40. Each guide groove 42 is trapezoidal, and a magnetic plate 43 repelling the magnetic force of the telescopic magnetic rod 40 is fixedly installed on its bottom inner wall. After the yarn breaks, it may spring back, and the broken end may splash onto other normal yarns and be difficult to hang down, making it difficult to capture the broken end. After the yarn breaks, the first cylinder 3 lifts the feed roller 2, causing the area between the lower limiting roller 5 and the upper limiting roller 6 to... The yarn loosens, and then the two second electric slide blocks 37 slide synchronously on the second slide rail 36 to above the pressure sensing plate 10 where the pressure changes. Then, the two second electric push rods 38 extend synchronously, driving the two combing rakes 39 to move relative to each other. When the combing rakes 39 initially move, they will be subjected to gravity, causing the telescopic magnetic rod 40 to move along the inclined groove of the guide groove 42. The combing rakes 39 will gradually insert into the yarn. Then, the telescopic magnetic rod 40 moves along the horizontal groove at the bottom of the guide groove 42 to comb the yarn, making it easier for the yarn ends to hang down. After the second electric push rods 38 have extended, the telescopic magnetic rod 40 will move to the bottom end of the guide groove 42 and move upward under the magnetic repulsion of the magnetic plate 43, causing the combing rakes 39 to be pulled out of the yarn. Then, the second electric push rods 38 will drive the combing rakes 39 to retract. The telescopic magnetic rod 40 will move along the horizontal groove at the top of the guide groove 42 to reset. During the reset process, the combing rakes 39 will no longer comb the yarn to prevent excessive pulling on the yarn.

[0021] Two first slide rails 15 are fixedly installed inside the frame 1. A first electric slide block 16 is slidably mounted on each first slide rail 15. A clamping plate 17 is fixedly mounted on each first electric slide block 16. A magnetic shaft 18 is slidably mounted on each clamping plate 17. A pulley 19 is rotatably mounted on each magnetic shaft 18. The two magnetic shafts 18 are arranged in a magnetically repulsive configuration. Magnetic blocks 20 for generating magnetic attraction force on the magnetic shafts 18 are symmetrically fixedly installed on the inner walls of both sides of the frame 1. A turntable 21 is rotatably mounted on each clamping plate 17. A rotating roller 22 that cooperates with the pulley 19 is rotatably mounted on each turntable 21. Each turntable 21 is provided with a slot 23 for limiting the magnetic shaft 18. A first electric slide block 16 is fixedly mounted on each first electric slide block 16 for pushing the turntable 21. Each electric push rod 24 has a gear 25 fixedly mounted on one side of each turntable 21. Each first electric push rod 24 has a baffle 26 fixedly mounted at its output end to limit the gear 25. Each baffle 26 has a rack 27 fixedly mounted on it to mesh with the gear 25. Each rack 27 has an electric shaft 28 rotatably mounted at one end. Each electric shaft 28 has an infrared sensor plate 29 fixedly mounted on it for detecting wire ends. Each infrared sensor plate 29 is located below the corresponding roller 22. Initially, the two first electric slide blocks 16 are located on opposite sides of the frame 1, and the first electric push rods 24 are in a retracted state. The slots 23 on the turntable 21 are horizontal. The magnetic shaft 18 is attracted by the magnetic block 20, causing the pulley 19 to slide to... At the center of clamping plate 17, infrared sensing plates 29 are also in a horizontal position. When the yarn breaks, the combing rake 39 first combs the yarn, causing the broken yarn to droop. Then, the two first electric slide blocks 16 will slide synchronously on the first slide rail 15 to above the pressure sensing plate 10 where the pressure changes. The two clamping plates 17 move relative to each other, and both ends of the broken yarn will be located between the two clamping plates 17. During the sliding of clamping plates 17, the magnetic shaft 18 and pulley 19 do not slide on the clamping plates 17. After the two clamping plates 17 have finished sliding, each pulley 19 and each roller 22 will abut against the other clamping plate 17. The two ends of the broken yarn will be located between the two sets of pulleys 19 and rollers 22 respectively. At this time, the two magnetic shafts 18 will be aligned and the distance from the magnetic block 20 will be... The yarn is far away and will not be affected by the magnetic attraction of the magnetic block 20. The two magnetic shafts 18 will be driven by the magnetic repulsion to move the two pulleys 19 in opposite directions, and the magnetic shafts 18 will be locked into the slots 23. At this time, the two sets of pulleys 19 and the rotating rollers 22 will respectively hold the two ends of the broken yarn. Then, the two first electric push rods 24 will extend. Through the meshing of the rack 27 and the gear 25, and the limiting of the magnetic shafts 18 by the slots 23, the turntable 21 will drive the pulleys 19 and the rotating rollers 22 to rotate 90 degrees until the yarn between the pulleys 19 and the rotating rollers 22 is in a horizontal state, while the broken end of the yarn continues to hang down. The broken end of the yarn is a certain distance away from the rotating rollers 22 and should be located below the infrared sensing plate 29. Therefore, the yarn is bent when passing the infrared sensing plate 29.The broken ends of the yarn do not contact the infrared sensor plate 29. As the first electric push rod 24 continues to extend, the baffle 26 abuts against the gear 25, pushing the turntable 21, roller 22, and pulley 19 to move synchronously. After straightening both ends of the broken yarn, the roller 22 and pulley 19 rotate, causing the broken ends to move upwards. When the broken ends reach contact with the infrared sensor plate 29, the first electric push rod 24 on that side stops extending. Once both first electric push rods 24 stop moving, it indicates that the two broken ends of the yarn have been found. Because the first cylinder 3 pushes the feed roller 2 upwards, the yarn in the area between the lower limit roller 5 and the upper limit roller 6 is lengthened to a certain extent. Therefore, when the first electric push rod 24 stops, the two broken ends are usually spaced at a specified interval, facilitating subsequent splicing.

[0022] An air splicer 30 for splicing yarn breaks is provided below one of the clamping plates 17 (the air splicer is a known existing mechanism, so it will not be described in detail here). Each clamping plate 17 has a slidingly mounted hanging plate 31, each made of magnetic material, and each hanging plate 31 has a stop bar 32, limited by a turntable 21, fixedly mounted on one side by two elastic rods 33. The air splicer 30 is fixedly connected to the lower end of one of the hanging plates 31, and a plug rod 34 is fixedly mounted on the lower end of the other hanging plate 31. The air splicer 30 has a socket 35 that mates with the plug rod 34. Initially and during the movement of the clamping plates 17, both hanging plates 31 are located in the middle position of the clamping plates 17 due to the magnetic attraction of the magnet 20. After the clamping plates 17 have finished moving, the plug rod 34 is inserted into the socket 35, causing the two hanging plates 31 to merge with the air splicer 30. When the first electric push rod 24... When the turntable 21 is pushed, the two stop bars 32 will be limited by the two turntables 21. Since the distance between the two yarn breaks is a specified distance and the elastic rods 33 on the two hanging plates 31 have the same elastic force, the two hanging plates 31 and the air splicer 30 will eventually move to the middle position of the two turntables 21, which makes it easier for the air splicer 30 to splice the two yarn breaks, reducing the overlapping part when splicing the yarn. Then the two electric rotating shafts 28 will drive the two infrared sensing plates 29 to rotate, no longer supporting the two yarn breaks. The two yarn breaks will fall into the air splicer 30 for splicing, which can accurately splice the yarn breaks, and the overlapping position of the splicing is always located at the yarn break. Furthermore, the length of the overlap during splicing can be controlled by adjusting the length of the yarn lifted by the warp roller 2, reducing the loss of yarn length after splicing and preventing the yarn from becoming too short after splicing, which would cause excessive tension changes.

[0023] Specifically, the yarn on the feed roller 2 is first passed sequentially through the upper end of the lower limit roller 5 and the lower end of the upper limit roller 6, and then fed into the subsequent cashmere fabric weaving mechanism. Then, the second cylinder 7 pushes the support rod 8 and the top thread ring 9 upwards. After the top thread ring 9 contacts the yarn, it lifts the yarn and evenly distributes it onto each top thread ring 9, ensuring that each first spring 11 experiences the same tension. The pressure sensed by the pressure sensing plate 10 represents the tension on the yarn. When the infrared yarn breakage detection device 14 detects a yarn breakage, and the corresponding pressure sensing plate 10 also shows a pressure change, it indicates that a yarn breakage has occurred on the corresponding top thread ring 9. At this time, the first cylinder 3 is extended, the motor 4 stops working, and the second cylinder 7 retracts. The top thread ring 9 no longer applies pressure to the yarn. The first cylinder 3 lifts the feed roller 2 upward, causing the yarn to fully relax. A portion of the yarn is pushed into the area between the lower limit roller 5 and the upper limit roller 6. Simultaneously, the feed roller 2 pulls one end of the connecting rope 45, which drives the two pressure plates 44 to move. The two pressure plates 44 then press against the upper end of the lower limit roller 5 and the lower end of the upper limit roller 6, respectively, fixing the yarn length in the area between the lower limit roller 5 and the upper limit roller 6. Then, the two second electric slide blocks 37 slide synchronously on the second slide rail 36 to above the pressure sensing plate 10 where the pressure changes. The two second electric push rods 38 extend synchronously, driving the two combing rakes 39 to move relative to each other. When the combing rakes 39 initially move, they are subjected to gravity, causing them to extend... The retractable magnetic rod 40 moves along the inclined groove of the guide groove 42, and the combing rake 39 gradually inserts into the yarn. Then, the retractable magnetic rod 40 moves along the horizontal groove at the bottom of the guide groove 42 to comb the yarn, making it easier for the yarn ends to hang down. After the second electric push rod 38 extends completely, the retractable magnetic rod 40 moves to the bottom end of the guide groove 42 and moves upward under the magnetic repulsion of the magnetic plate 43, causing the combing rake 39 to be pulled out of the yarn. Then, the second electric push rod 38 drives the combing rake 39 to retract, and the retractable magnetic rod 40 moves back to its original position along the horizontal groove at the top of the guide groove 42. During the resetting process, the combing rake 39 no longer combs the yarn. Then, the two first electric slide blocks 16 will also slide synchronously on the first slide rail 15 to the pressure sensing plate 10 where the pressure changes. Above, the two clamping plates 17 move relative to each other, with both ends of the broken yarn positioned between them. After the two clamping plates 17 have slid completely, each pulley 19 and each roller 22 will abut against the other clamping plate 17. The two ends of the broken yarn will be positioned between the two sets of pulleys 19 and rollers 22 respectively. At this time, the two magnetic shafts 18 will be subjected to magnetic repulsion, causing the two pulleys 19 to move in opposite directions and engage with the slots 23. The two sets of pulleys 19 and rollers 22 will then clamp the two ends of the broken yarn. Then, the two first electric push rods 24 will extend, causing the turntable 21 to rotate the pulleys 19 and rollers 22 by 90 degrees until the yarn between the pulleys 19 and rollers 22 is horizontal. At this point, the baffle 26 will abut against the gear 25.The turntable 21, roller 22, and pulley 19 move synchronously, straightening both ends of the broken yarn. The roller 22 and pulley 19 then rotate, causing the broken ends of the yarn to move upwards. When the broken ends reach the infrared sensor plate 29, the first electric push rod 24 on that side stops extending. Once both first electric push rods 24 stop moving, it indicates that the two broken ends of the yarn have been located. Simultaneously, as the clamping plate 17 completes its movement, the insertion rod 34 inserts into the insertion hole 35, merging the two hanging plates 31 with the air splicer 30. When the first electric push rod 24 pushes the turntable 21, the two stop bars 32 are subjected to two rotational forces. When disc 21 is stopped, the two hanging plates 31 and the air splicer 30 will eventually move to the middle position of the two turntables 21. Then, the two electric rotating shafts 28 will drive the two infrared sensing plates 29 to rotate, no longer supporting the two broken ends of the yarn. The two broken ends of the yarn will fall into the air splicer 30 for splicing. After splicing is completed, the first electric slide block 16 drives the clamping plate 17 to reset, so that the pulley 19 and the rotating roller 22 no longer clamp the yarn. Then, the first electric push rod 24 resets, finally restoring the pulley 19 and the rotating roller 22 to a horizontal state. Then, the magnetic shaft 18, driven by the magnetic attraction of the magnetic block 20, drives the pulley 19 to reset to the middle section of the clamping plate 17.

[0024] A method for splicing cashmere fabric with a self-splitting mechanism for detecting fabric breakage includes the following steps: S1. The yarn on the warp roller 2 is passed sequentially through the upper end of the lower limit roller 5 and the lower end of the upper limit roller 6, and then fed into the subsequent cashmere fabric weaving mechanism. S2. Control the second cylinder 7 to push the support rod 8 and the top thread ring 9 upward, and distribute the yarn evenly on each top thread ring 9. The top thread ring 9 lifts the yarn, and the pressure sensed by the pressure sensing plate 10 represents the tension of the yarn. S3. When the infrared yarn breakage detection device 14 detects a yarn breakage and the corresponding pressure sensing plate 10 also changes pressure, the first cylinder 3 will push the warp roller 2 upward to loosen the yarn completely, the motor 4 will stop working and the yarn will stop moving, the second cylinder 7 will retract to stop the top thread ring 9 from applying pressure to the yarn, and at the same time the connecting rope 45 will drive the two pressure plates 44 to move, so that the yarn length in the area between the lower limit roller 5 and the upper limit roller 6 is fixed. S4. The two second electric slide blocks 37 slide synchronously on the corresponding second slide rails 36 to above the pressure sensing plate 10 where the pressure changes. Then the two second electric push rods 38 extend synchronously, driving the two combing rakes 39 to move relative to each other, so that the combing rakes 39 comb the yarn and the broken ends of the yarn hang down. S5. The two first electric slide blocks 16 slide synchronously on the corresponding first slide rails 15 to above the pressure sensing plate 10 where the pressure changes. The two ends of the broken yarn hang down between the two clamping plates 17. The two magnetic shafts 18 are driven by magnetic repulsion to drive the two pulleys 19 to move in opposite directions. The two sets of pulleys 19 and the rotating rollers 22 respectively clamp the two ends of the broken yarn. Then, the two first electric push rods 24 extend, causing the turntable 21 to drive the pulleys 19 and the rotating rollers 22 to rotate 90 degrees. Then, the turntable 21, the rotating rollers 22 and the pulleys 19 move synchronously to straighten the two ends of the broken yarn. The broken ends of the yarn move upward continuously. When the broken ends of the yarn contact the infrared sensing plate 29, the first electric push rod 24 on that side will stop extending until the two broken ends of the yarn are found. S6. The two baffles 32 will be limited by the two turntables 21, so that the two hanging plates 31 and the air splicer 30 move to the middle position of the two turntables 21. Then the two electric rotating shafts 28 drive the two infrared sensing plates 29 to rotate, no longer supporting the two broken ends of the yarn. The two broken ends of the yarn will fall into the air splicer 30 for splicing.
