Description

Technical Field

[0001] This invention relates to the field of yarn knotting, specifically to a yarn end rotation knotting structure. Background Technology

[0002] In the field of textile technology, yarn splicing is a core process that determines the quality and efficiency of subsequent 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 an automated knotting machine that mimics manual knotting actions, automating the entire yarn knotting process and simultaneously improving both efficiency and quality.

[0003] In the prior art, the yarn end rotating knotting structure includes a yarn release sleeve, a yarn hook rod, a working sleeve, a transmission gear, and a sliding sleeve. The sliding sleeve is tightly engaged with the transmission gear to maintain relative stillness. The rotating hook is fixed to the transmission gear, and the transmission gear meshes with the drive gear on the motor drive shaft.

[0004] However, when the transmission gear meshes with the driving gear for transmission, as the transmission gear rotates, the lubricating oil between the transmission gear and the driving gear will be thrown off the tooth surface under the action of centrifugal force, resulting in poor lubrication on the tooth surface and aggravating the wear of the tooth surface. Summary of the Invention

Several sets of extension rods are fixed on the inner wall of the oil storage cavity. The several sets of extension rods are circumferentially distributed about the axis of the oil filling hole. The extension rods are rectangular rod structures. The other end of the extension rods is fixed with the same set of spring plates, which are circular plate structures.

[0011] Preferably, a spring is fixed to one end of the spring plate near the oil filling hole, and a sealing block is fixed to the other end of the spring, with one end of the sealing block movably inserted into the oil filling hole.

[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 1-7The present invention provides a technical solution: a yarn end rotating knotting structure, comprising: a transmission gear 1, an oil storage cavity 2 on the transmission gear 1, a plurality of oil holes 3 on the transmission gear 1, the oil holes 3 communicating with the oil storage cavity 2, a plurality of valve grooves 4 on the side wall of the transmission gear 1, the plurality of valve grooves 4 communicating with the plurality of oil holes 3 respectively, a valve plate 5 slidably connected in the valve groove 4, and spring plates 9 movably installed at both symmetrical ends of the valve plate 5.

[0021] Lubricating oil is stored in the oil reservoir 2 in advance. When the transmission gear 1 meshes with the drive gear and rotates under the drive of the drive gear, the rotation of the valve plate 5 lags behind that of the transmission gear 1 due to inertia. This causes the valve plate 5 to move away from the oil hole 3. The lubricating oil stored in the oil reservoir 2 gradually flows from the oil hole 3 to the tooth surface of the transmission gear 1 under the action of centrifugal force, thereby achieving the function of adding lubricating oil to the tooth surface of the transmission gear 1 during operation and improving the lubrication between the transmission gear 1 and the drive gear.

[0022] Example 2: Based on Example 1, in order to prevent lubricating oil from leaking out of the oil hole 3 when the transmission gear 1 is not rotating, spring plates 9 are movably installed at both ends of the valve plate 5. The valve plate 5 has a fan-shaped plate structure, and sealing gaskets 6 are fixed on the two symmetrical end faces of the valve plate 5. The end of the sealing gasket 6 away from the valve plate 5 abuts against the inner wall of the valve groove 4.

[0023] When the transmission gear 1 rotates, as the valve plate 5 moves away from the oil hole 3, the spring plates 9 at both ends of the valve plate 5 are compressed and stretched respectively. When the transmission gear 1 stops rotating, as the two sets of spring plates 9 return to their original shape under the elastic action, the valve plate 5 is pushed and pulled back into the oil hole 3 again. The sealing gasket 6 abuts against the inner wall of the valve groove 4, sealing the gap between the inner wall of the valve groove 4 and the valve plate 5, thereby preventing lubricating oil from leaking out from the oil hole 3 when the transmission gear 1 is not rotating.

[0024] Example 3: Based on Example 2, in order to realize the assembly and disassembly of the spring plate 9, a first slider 11 is fixed on each of the two symmetrical inner walls of the valve groove 4, and a second slider 28 is fixed on each of the two symmetrical end faces of the valve plate 5. The first slider 11 and the second slider 28 have a "7" shaped rod structure; the spring plate 9 has a "Z" shaped plate structure. A first mounting plate 7 is fixed to the end of the spring plate 9 near the valve plate 5, and a second mounting plate 8 is fixed to the end of the spring plate 9 away from the valve plate 5. Both the first mounting plate 7 and the second mounting plate 8 have a fan-shaped plate structure. A second slide rail 27 is provided on the first mounting plate 7, and a first guide rail 10 is provided on the second mounting plate 8. Both the first guide rail 10 and the second slide rail 27 have a "7" shaped groove structure. The first slider 11 of each group is movably inserted into the two groups of first guide rails 10, and the two groups of second sliders 28 are movably inserted into the two groups of second slide rails 27. The transmission gear 1 is provided with a mounting groove 23, which is connected to the valve groove 4. The valve groove 4 has an opening on the side of the transmission gear 1. A cover plate 21 is movably inserted into the opening of the valve groove 4. The cover plate 21 has a fan-shaped plate structure. Screw hole plates 22 are fixed on the two symmetrical end faces of the cover plate 21. The screw hole plates 22 are movably inserted into the mounting groove 23. Screws 24 are rotatably connected to the screw hole plates 22. Screw holes 25 are provided on the inner wall of the bottom end of the mounting groove 23. Screws 24 are installed in the screw holes 25 by threaded connection. A sealing plate 26 is movably inserted into the opening of the mounting groove 23.

[0025] Pry out the sealing plate 26 of the sealing mounting groove 23, and then use a screwdriver to unscrew the screw 24 on the screw hole plate 22. The screw 24 will come out of the screw hole 25, allowing the cover plate 21 to come out of the valve groove 4. Then, use tweezers to clamp the spring plate 9, and then you can pull the valve plate 5, the first mounting plate 7, the second mounting plate 8 and the spring plate 9 out of the valve groove 4 together, so as to facilitate the cleaning or replacement of the valve plate 5 and the spring plate 9. After cleaning and replacing the valve plate 5 and the spring plate 9, let the second slider 28 re-insert into the second slide rail 27, and then put the valve plate 5 and the spring plate 9 back into the valve groove 4. When putting them back in, let the first slider 11 insert into the first guide rail 10, and then reinstall the cover plate 21 into the valve groove 4, so as to realize the disassembly and assembly of the spring plate 9.

[0026] Example 4: Based on Example 3, in order to add lubricating oil to the oil storage chamber 2, an oil filling hole 12 is provided on the transmission gear 1. The oil filling hole 12 has a circular hole structure and communicates with the oil storage chamber 2. Several sets of extension rods 29 are fixed on the inner wall of the oil storage chamber 2. The several sets of extension rods 29 are circumferentially distributed about the axis of the oil filling hole 12. The extension rods 29 have a rectangular rod structure. The other end of the extension rods 29 is fixed with the same set of spring plates 13. The spring plates 13 have a circular plate structure. A spring 15 is fixed at one end of the spring plate 13 near the oil filling hole 12. A sealing block 14 is fixed at the other end of the spring 15. One end of the sealing block 14 is movably inserted into the oil storage chamber 2. In the oil filling hole 12, a sealing groove 19 is provided on the side wall of the sealing block 14. The sealing groove 19 has an annular groove structure. A sealing ring 20 is fixed in the sealing groove 19. The sealing ring 20 has a circular plate structure. The outer ring of the sealing ring 20 is slidably connected to the inner wall of the oil filling hole 12. A syringe 16 is movably inserted into the oil filling hole 12. The syringe 16 has a circular cylindrical structure. One end of the syringe 16 extends into the oil storage cavity 2 and has an injection port 17. A push rod 18 is movably inserted into the cylinder of the syringe 16. The push rod 18 has an "I" shaped cylindrical rod structure. A rubber head 30 is fixed at one end of the push rod 18 that extends into the syringe 16. The rubber head 30 has a circular plate structure.

[0027] Using syringe 16 to draw lubricating oil, and then inserting syringe 16 into oil filling hole 12, as syringe 16 is inserted, sealing block 14 is pushed out of oil filling hole 12, spring 15 is compressed by spring plate 13 and sealing block 14, and then push rod 18 to inject the lubricating oil in syringe 16 from injection port 17 into oil storage chamber 2, thus adding lubricating oil to oil storage chamber 2; after adding, syringe 16 is pulled out from oil filling hole 12, so that sealing block 14 can be reinserted into oil filling hole 12, and sealing ring 20 in sealing groove 19 seals the gap between sealing block 14 and oil filling hole 12 to prevent lubricating oil from leaking from oil filling hole 12.

[0028] In actual use, the syringe 16 is used to draw lubricating oil, and then the syringe 16 is inserted into the oil filling hole 12. As the syringe 16 is inserted, the sealing block 14 is pushed out of the oil filling hole 12. The spring 15 is compressed by the spring plate 13 and the sealing block 14, and then the push rod 18 is pushed to inject the lubricating oil in the syringe 16 from the injection port 17 into the oil storage chamber 2, thus adding lubricating oil to the oil storage chamber 2. After adding, the syringe 16 is pulled out from the oil filling hole 12, and the sealing block 14 can be reinserted into the oil filling hole 12. The sealing ring 20 in the sealing groove 19 seals the sealing block. The gap between the 14 and the oil filling hole 12 is sealed to prevent lubricating oil from leaking from the oil filling hole 12. When the transmission gear 1 meshes with the drive gear and rotates under the drive gear, the rotation of the valve plate 5 lags behind that of the transmission gear 1 due to inertia. This causes the valve plate 5 to move away from the oil hole 3. The lubricating oil stored in the oil storage chamber 2 gradually flows from the oil hole 3 to the tooth surface of the transmission gear 1 under the action of centrifugal force, thereby achieving the function of adding lubricating oil to the tooth surface of the transmission gear 1 during operation and improving the lubrication between the transmission gear 1 and the drive gear.
