Description

Technical Field

[0001] This invention relates to the field of yarn unwinding structures, specifically a yarn unwinding structure after knotting. Background Technology

[0002] In the field of textile technology, yarn splicing is a core process that determines the quality and efficiency of subsequent textile production. Currently, yarn splicing and knotting are mostly done manually. However, manual knotting has many drawbacks: firstly, it is inefficient and costly, failing to meet the demands of large-scale production in the modern textile industry; secondly, it is difficult to maintain uniform tension during manual knotting, easily leading to loose yarn and severely affecting yarn quality stability. Therefore, there is an urgent need for a simulated manual automatic knotting machine that automates the entire yarn knotting process, thereby simultaneously improving efficiency and quality. Furthermore, after knotting, the yarn needs to be untied from the knot, requiring a yarn untying mechanism to assist the knotting machine, further improving its overall efficiency.

[0003] The existing yarn untying structure includes a yarn hook rod, a yarn untying sleeve, and a working sleeve. The working sleeve moves along the axial direction of the yarn untying sleeve to remove the knotted yarn from the yarn hook rod and the yarn untying sleeve.

[0004] However, in the existing yarn unwinding structure, the gap between the hook rod, the unwinding sleeve, and the working sleeve is very small. When adding lubricant between the hook rod, the unwinding sleeve, and the working sleeve, it can only be applied to the parts of the hook rod and the unwinding sleeve that are exposed outside the working sleeve. Then, the movement of the hook sleeve gradually squeezes the lubricant into the gap between the hook rod, the unwinding sleeve, and the working sleeve, resulting in extremely low lubricant addition efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a structure for untying yarn after knotting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn untying structure after knotting, comprising: a yarn hook rod, a yarn untying sleeve, and a working sleeve, wherein the working sleeve is slidably connected to the yarn hook rod and the yarn untying sleeve, wherein the yarn untying sleeve is provided with an oil storage cavity, an application hole, and an injection port, wherein the application hole and the injection port are both connected to the oil storage cavity, wherein a valve plate is movably inserted into the application hole, and the application hole is located at the contact position between the yarn untying sleeve and the working sleeve.

[0007] Preferably, the yarn stripping sleeve has a valve groove, which is a rectangular groove structure. The valve groove is connected to the coating hole, and a valve plate is movably inserted into the valve groove. The valve plate is a rectangular plate structure.

[0008] Preferably, the valve groove has an opening at the end of the yarn-removing sleeve, a spring plate is movably installed at the opening of the valve groove, a spring is fixed on the inner wall of the spring plate, and the other end of the spring abuts against the surface of the valve plate.

[0009] Preferably, the yarn stripping sleeve has a push rod hole and a push plate groove. The push rod hole has a circular groove structure, and the push plate groove has a rectangular groove structure. One end of the push rod hole is connected to the valve groove, and the other end of the push rod hole is connected to the push plate groove. The push plate groove is located at the part of the yarn stripping sleeve that extends out of the working sleeve.

[0010] Preferably, a push rod is movably inserted into the push rod hole. The push rod has a round rod structure. One end of the push rod extends into the valve groove and is fixed to the valve plate. The other end of the push rod extends into the push plate groove and is fixed to the push plate. The push plate is slidably connected in the push plate groove and has a rectangular plate structure.

[0011] Preferably, the yarn stripping sleeve has a sealing plate groove, and a sealing plate is slidably connected in the sealing plate groove. One end of the sealing plate extends into the opening of the push plate groove and is fixed on the push plate.

[0012] Preferably, the valve groove has a spring plate mounting groove at its opening, a threaded groove on the inner wall of the spring plate mounting groove, a screw rotatably connected to the spring plate, the screw rotatably connected to the threaded groove, an internal thread on the inner wall of the threaded groove, an external thread on the screw shank, the internal thread of the threaded groove mates with the external thread of the screw, a screw joint groove is provided on the spring plate, a screw joint plate is fitted and fixed on the screw shank, the screw joint groove has a circular groove structure, the screw joint plate has a circular ring plate structure, and the screw joint plate is rotatably connected to the screw joint groove.

[0013] Preferably, a protective block is movably inserted into the spring plate mounting groove, and the protective block and the spring plate mounting groove are in transition fit, with a raised groove provided on the protective block.

[0014] Preferably, the filling port has a circular hole structure, and a stopper is movably inserted into the filling port. The stopper has a circular plate structure, and the stopper and the filling port are fitted with a transition fit. A pull block is fixed to the top of the stopper.

[0015] Preferably, a sealing groove is provided on the inner wall of the valve groove. The sealing groove is an annular groove and is formed around the coating hole. A sealing ring is fixed in the sealing groove, and one end of the sealing ring extending out of the sealing groove abuts against the valve plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The yarn unwinding structure proposed in this invention allows lubricating oil to be pre-poured into the oil storage chamber through the filling port. After the filling port is sealed and the valve plate is removed from the coating hole, the working sleeve moves axially back and forth on the unwinding sleeve while the hook rod, unwinding sleeve, and working sleeve are rotated. This allows the lubricating oil in the oil storage chamber to be applied from the coating holes at both ends of the unwinding sleeve to the top of the hook rod and the inner wall of the working sleeve. This ensures that the lubricating oil is directly applied to the gap between the hook rod, unwinding sleeve, and working sleeve, and is quickly squeezed and evenly applied with the movement of the working sleeve, resulting in higher lubricating oil application efficiency.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0020] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: a yarn untying structure after knotting, comprising: a yarn hook rod 1, a yarn untying sleeve 2, and a working sleeve 3. The working sleeve 3 is slidably connected to the yarn hook rod 1 and the yarn untying sleeve 2. The yarn untying sleeve 2 is provided with an oil storage cavity 4, an application hole 5, and an injection port 14. The application hole 5 and the injection port 14 are both connected to the oil storage cavity 4. A valve plate 6 is movably inserted into the application hole 5. The application hole 5 is located at the contact position between the yarn untying sleeve 2 and the working sleeve 3.

[0021] Lubricating oil is poured into the oil storage chamber 4 through the filling port 14 in advance. Then, the filling port 14 is sealed, and the valve plate 6 is removed from the coating hole 5. While the working sleeve 3 moves back and forth along the axis on the stripping sleeve 2, the hook rod 1, stripping sleeve 2 and working sleeve 3 are rotated. This allows the lubricating oil in the oil storage chamber 4 to be coated from the coating holes 5 at both ends of the stripping sleeve 2 onto the top of the hook rod 1 and the inner wall of the working sleeve 3. This allows the lubricating oil to be directly coated into the gap between the hook rod 1, stripping sleeve 2 and working sleeve 3, and is quickly squeezed and coated evenly with the movement of the working sleeve 3, making the coating efficiency of the lubricating oil higher.

[0022] Example 2: Based on Example 1, in order to realize the movement of the valve plate 6, a valve groove 27 is provided on the yarn stripping sleeve 2. The valve groove 27 has a rectangular groove structure and is connected to the coating hole 5. The valve plate 6 is movably inserted into the valve groove 27 and has a rectangular plate structure. An opening is provided at the end of the yarn stripping sleeve 2 in the valve groove 27. A spring plate 17 is movably installed at the opening of the valve groove 27. A spring 9 is fixed on the inner wall of the spring plate 17, and the other end of the spring 9 abuts against the surface of the valve plate 6. A push rod hole 7 and a push plate groove 10 are provided on the yarn stripping sleeve 2. The push rod hole 7 has a circular groove structure, and the push plate groove 10 has a rectangular groove structure. One end of hole 7 is connected to valve groove 27, and the other end of push rod hole 7 is connected to push plate groove 10. Push plate groove 10 is opened at the part of the yarn stripping sleeve 2 that extends out of working sleeve 3. Push rod 8 is movably inserted into push rod hole 7. Push rod 8 has a round rod structure. One end of push rod 8 extends into valve groove 27 and is fixed on valve plate 6. The other end of push rod 8 extends into push plate groove 10 and is fixed with push plate 11. Push plate 11 is slidably connected in push plate groove 10. Push plate 11 has a rectangular plate structure. Sealing plate groove 12 is opened on yarn stripping sleeve 2. Sealing plate 13 is slidably connected in sealing plate groove 12. One end of sealing plate 13 extends into the opening of push plate groove 10 and is fixed on push plate 11.

[0023] Pushing the push plate 11 causes it to move within the push plate groove 10, which in turn pushes the push rod 8. The push rod 8 then pushes the valve plate 6, causing the valve plate 6 to move away from the application hole 5 and retract completely into the valve groove 27. This compresses the spring 9 by the valve plate 6 and the spring plate 17. When the push plate 11 is released, the spring 9, under its own elasticity, pushes the valve plate 6, which is then pushed back into the application hole 5. When the push plate 11 is not pushed, one end of the sealing plate 13 extends from the sealing plate groove 12 and blocks the opening of the push plate groove 10, preventing debris from falling into the push plate groove 10 and affecting the movement of the push plate 11.

[0024] Example 3: Based on Example 2, in order to replace the spring 9, a spring plate mounting groove 18 is provided at the opening of the valve groove 27. A screw groove 19 is provided on the inner wall of the spring plate mounting groove 18. A screw 20 is rotatably connected to the spring plate 17. The screw 20 is rotatably connected in the screw groove 19. An internal thread is provided on the inner wall of the screw groove 19. An external thread is provided on the shank of the screw 20. The internal thread of the screw groove 19 mates with the external thread of the screw 20. A screw-in groove 21 is provided on the spring plate 17. A screw-in plate 22 is fitted and fixed on the shank of the screw 20. The screw-in groove 21 has a circular groove structure. The screw-in plate 22 has a circular annular plate structure. The screw-in plate 22 is rotatably connected in the screw-in groove 21. A protective block 23 is movably inserted into the spring plate mounting groove 18. The protective block 23 and the spring plate mounting groove 18 adopt a transition fit. A raised groove 24 is provided on the protective block 23.

[0025] After inserting the screwdriver into the prying groove 24, pry the protective block 23 out of the spring plate mounting groove 18. Then, turn the screw 20 with the screwdriver to remove it from the screw groove 19. As the screw 20 moves, the connecting plate 22 presses against the inner wall of the connecting groove 21, pushing the spring plate 17 out of the valve groove 27. As the spring plate 17 is removed from the valve groove 27, the spring 9 is also removed from the valve groove 27. Then, install the new spring plate 17 and the spring 9 back into the valve groove 27 to replace the spring 9. After replacement, insert the protective block 23 back into the spring plate mounting groove 18 to seal the spring plate mounting groove 18, providing a sealed environment for the screw 20 and preventing the screw 20 from being contaminated by lubricating oil.

[0026] Example 4: Based on Example 3, in order to prevent lubricating oil leakage, the filling port 14 has a circular hole structure, and a plug 15 is movably inserted into the filling port 14. The plug 15 has a circular plate structure, and the plug 15 and the filling port 14 are fitted with a transition fit. A pull block 16 is fixed to the top of the plug 15. A sealing groove 25 is provided on the inner wall of the valve groove 27. The sealing groove 25 is an annular groove. The sealing groove 25 is opened around the coating hole 5. A sealing ring 26 is fixed in the sealing groove 25. One end of the sealing ring 26 extends out of the sealing groove 25 and abuts against the valve plate 6.

[0027] A plug 15 is inserted into the filling port 14. The plug 15 and the filling port 14 are fitted together with an overfit, so that the gap between the filling port 14 and the plug 15 is insufficient for lubricating oil to pass through. In order to ensure the movement of the valve plate 6, the valve plate 6 and the valve groove 27 are fitted together with a clearance. A sealing groove 25 is opened on the inner wall of the valve groove 27. A sealing ring 26 is fixed in the sealing groove 25. When the valve plate 6 is inserted into the coating hole 5, the sealing ring 26 abuts against the valve plate 6 and seals the gap between the inner wall of the spring 9 and the valve plate 6, thereby preventing the leakage of lubricating oil.

[0028] In actual use, a plug 15 is inserted into the filling port 14. An overfit is used between the plug 15 and the filling port 14, ensuring that the gap between the filling port 14 and the plug 15 is insufficient for lubricating oil to pass through. To ensure the movement of the valve plate 6, a clearance fit is used between the valve plate 6 and the valve groove 27. A sealing groove 25 is formed on the inner wall of the valve groove 27, and a sealing ring 26 is fixed in the sealing groove 25. When the valve plate 6 is inserted into the application hole 5, the sealing ring 26 abuts against the valve plate 6, sealing the gap between the inner wall of the spring 9 and the valve plate 6, thus preventing lubricating oil leakage. Pushing the push plate 11, the push plate 11 moves in the push plate groove 10, pushing the push rod 8, which in turn pushes the valve plate 6. The valve plate 6 moves away from the application hole 5 and completely retracts into the valve groove 27, compressing the spring 9 by the valve plate 6 and the spring plate 17. When the push plate 11 is released, the spring 9, under its own elasticity, spring... 9. Push the valve plate 6, which can be pushed back into the coating hole 5. When the push plate 11 is not pushed, one end of the sealing plate 13 extends from the sealing plate groove 12 and blocks the opening of the push plate groove 10, which can prevent debris from falling into the push plate groove 10 and affecting the movement of the push plate 11. The lubricating oil is poured into the oil storage chamber 4 in advance through the filling port 14, and then the filling port 14 is sealed. After the valve plate 6 is removed from the coating hole 5, the working sleeve 3 is moved back and forth along the axis on the yarn stripping sleeve 2, while the yarn hook rod 1, yarn stripping sleeve 2 and working sleeve 3 are rotated, so that the lubricating oil in the oil storage chamber 4 is coated from the coating holes 5 at the upper and lower ends of the yarn stripping sleeve 2 onto the top of the yarn hook rod 1 and the inner wall of the working sleeve 3. This makes the lubricating oil directly coated in the gap between the yarn hook rod 1, yarn stripping sleeve 2 and working sleeve 3, and is quickly squeezed and coated evenly with the movement of the working sleeve 3, making the coating efficiency of the lubricating oil higher.
