Description

Technical Field

[0001] This application relates to the field of yarn dyeing and processing, and in particular to a leak-proof device for a yarn dyeing rack. Background Technology

[0002] In the field of yarn package dyeing, the dye supply pipe, as a key component for conveying dye liquor to the yarn packages, plays a crucial role in the dyeing quality and production efficiency due to its sealing performance at the connection with the dyeing rack. With the development of the yarn package dyeing industry and the continuous expansion of production scale, the requirements for the reliability and stability of dyeing equipment are becoming increasingly stringent. In actual production, the dye supply pipe needs to frequently convey dye liquor, and the dye liquor has a certain degree of corrosiveness and pressure, which places extremely high sealing requirements on the connection between the top of the dye supply pipe and the dyeing rack.

[0003] Currently, most existing technologies address the sealing issue at the connection between the liquid inlet tube and the dyeing rack by employing traditional sealing structures, such as simple rubber sealing rings. This sealing method utilizes the elasticity of rubber by installing a rubber sealing ring on the contact surface between the liquid inlet tube and the dyeing rack. To a certain extent, this sealing structure can prevent dye leakage at the connection point, ensuring the normal operation of the dyeing process.

[0004] However, traditional single rubber sealing rings are prone to wear and tear during long-term use due to repeated friction with the connection points, leading to a decline in sealing performance. This can cause dye leakage, affecting dyeing quality and resulting in uneven dyeing of yarn packages. Moreover, frequent replacement of rubber sealing rings increases maintenance costs and reduces production efficiency. Utility Model Content

[0005] To address the aforementioned issues, this application provides a leak-proof device for yarn dyeing racks.

[0006] This application provides a leak-proof device for yarn dyeing racks, which adopts the following technical solution: A leak-proof device for a yarn dyeing rack includes a dyeing rack, a liquid-conducting pipe, and a leak-proof mechanism. One end of the liquid-conducting pipe is fixedly connected to the dyeing rack. The dyeing rack has a connecting rod, one end of which is fixedly connected to the dyeing rack, and the other end of which passes through the liquid-conducting pipe. The leak-proof mechanism includes a leak-proof component and a locking component. The leak-proof component and the locking component are sequentially sleeved on the connecting rod. The leak-proof component abuts against one end of the liquid-conducting pipe, and one end of the locking component abuts against the leak-proof component. The locking component is rotatably connected to the connecting rod.

[0007] By adopting the above technical solution, the liquid-passing pipe is fixedly connected to the dyeing rack, the connecting support rod passes through the liquid-passing pipe, and the leak-stopping component and the locking component are sequentially fitted onto the connecting support rod and abut against each other. The locking component is rotatably connected to the connecting support rod, which can prevent the dye liquor from leaking from the connection between the liquid-passing pipe and the dyeing rack, ensuring the normal operation of the dyeing process and improving the dyeing quality.

[0008] Preferably, the connecting support rod has a first sleeve and a second sleeve, the diameter of the first sleeve is larger than that of the second sleeve, and the surface of the first sleeve is smooth. The leak-proof component is fitted onto the first sleeve, and the locking component is rotatably connected to the second sleeve.

[0009] By adopting the above technical solution, the connecting support rod is equipped with a first sleeve and a second sleeve with different diameters and surface characteristics, which makes it easy for the leak-stopping component to be fitted onto the smooth first sleeve. The locking component is rotatably connected to the second sleeve, which enables the leak-stopping component and the locking component to better cooperate to achieve the leak-stopping function, avoid dye liquor leakage, improve dyeing quality and production efficiency, reduce the problem of uneven dyeing of yarn packages caused by dye liquor leakage, and also reduce the maintenance costs caused by frequent replacement of sealing components.

[0010] Preferably, the leak-stopping component includes a leak-stopping body, which is fitted onto the first sleeve portion; the leak-stopping body has a first receiving portion and a second receiving portion, the first receiving portion being disposed near the liquid-flowing pipe, and the second receiving portion being disposed on the middle part of the leak-stopping body and away from the liquid-flowing pipe; a first sealing portion is embedded in the first receiving portion, the first sealing portion abutting against the liquid-flowing pipe and wrapping around the first sleeve portion; a second sealing portion is embedded in the second receiving portion, and the second sealing portion wraps around the first sleeve portion.

[0011] By adopting the above technical solution, a leak-stopping body is installed in the first sleeve of the connecting support rod in the leak-stopping device of the yarn dyeing rack, which can provide initial protection for this part. A first sealing ring is embedded in the first receiving part of the leak-stopping body near the liquid pipe, so that it abuts against the liquid pipe and wraps the first sleeve, which can enhance the sealing between the liquid pipe and the connecting support rod and prevent the dye liquor from leaking from this connection. A second sealing ring is embedded in the second receiving part in the middle of the leak-stopping body away from the liquid pipe and wraps the first sleeve, which further improves the sealing performance of the connection part, avoids the problem of decreased sealing performance and dye liquor leakage caused by the wear of a single sealing ring, ensures dyeing quality, and at the same time reduces maintenance costs and improves production efficiency.

[0012] Preferably, the leak-stopping body has a third receiving portion, which is located near the locking assembly; a third sealing portion is embedded in the third receiving portion, which wraps around the first sleeve portion.

[0013] By adopting the above technical solution, a third receiving part is set on the leak-stopping body near the locking component, and a third sealing part is embedded to wrap the first sleeve part. This can increase the sealing points, prevent the dye liquor from leaking from this part, improve the sealing performance of the connection between the liquid pipe and the dyeing rack, prevent the dyeing quality from being affected by insufficient dye liquor leakage pressure, resulting in uneven dyeing of the yarn package, reduce maintenance costs caused by sealing problems, and improve production efficiency.

[0014] Preferably, the locking assembly includes a locking body, which is fitted onto the second sleeve and rotatably connected to the second sleeve; the locking body abuts against the leak-stopping body and the third sealing part respectively.

[0015] By adopting the above technical solution, the locking body is fitted onto the second sleeve and rotatably connected to it, making the position of the locking body adjustable. At the same time, the locking body abuts against the leak-proof body and the third sealing part, which enhances the tightness between the components, further improves the sealing effect of the connection between the liquid pipe and the dyeing rack, reduces dye leakage, improves dyeing quality and production efficiency, avoids uneven dyeing of yarn packages caused by dye leakage, and also reduces maintenance costs.

[0016] Preferably, the third sealing part has a conical part that is inserted into the locking body.

[0017] By adopting the above technical solution, the leak-stopping mechanism is fitted onto the connecting part to prevent dye liquor leakage. The first and second sets of the connecting rod with different diameters facilitate the installation and cooperation of the leak-stopping component and the locking component. The multiple sealing rings can improve the sealing effect. The conical part of the third sealing part is inserted into the locking body, which further enhances the sealing between the third sealing part and the locking body, effectively preventing dye liquor from leaking from this part. This avoids affecting the dyeing quality and causing uneven dyeing of the yarn due to dye liquor leakage. At the same time, it reduces the need for frequent replacement of sealing rings, lowers maintenance costs, and improves production efficiency.

[0018] Preferably, the leak-stopping body has a positioning part, and the locking body has a fitting part, with the fitting part inserted into the positioning part.

[0019] By adopting the above technical solution, one end of the liquid-passing pipe is fixedly connected to the dyeing rack, one end of the connecting support rod is connected to the dyeing rack and the other end passes through the liquid-passing pipe, and the leak-stopping component and the locking component are sequentially fitted onto the connecting part. The connecting support rod is divided into a first sleeve and a second sleeve with different diameters. The leak-stopping component is fitted onto the first sleeve, and the locking component is rotatably connected to the second sleeve. The leak-stopping body has a first, second, and third receiving part and is respectively fitted with a first, second, and third sealing part for sealing. The locking body is fitted onto the second sleeve and abuts against the leak-stopping body and the third sealing part. On this basis, the positioning part on the leak-stopping body and the fitting part on the locking body cooperate to enable the leak-stopping body and the locking body to be accurately assembled and positioned, ensuring that their relative positions are stable, further enhancing the sealing and stability of the device, preventing the dye liquor leakage from causing the pressure to be too low, affecting the dyeing quality, and avoiding increased costs and reduced production efficiency due to frequent maintenance and replacement of parts.

[0020] Preferably, the locking body has a force-bearing part, and the force-bearing part is integrally formed with the locking body.

[0021] By adopting the above technical solution, a force-bearing part, namely a ring handle, is integrally formed with the locking body, which makes it convenient for operators to rotate the locking body and adjust the connection state of the leak-stopping mechanism, thereby improving the convenience and efficiency of operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting multiple sealing rings, the problem of decreased sealing performance and dye leakage caused by wear of a single sealing ring is avoided, thus ensuring dyeing quality and making the dyeing of yarn packages more uniform; 2. It reduces the frequency of replacement due to seal wear, thus lowering maintenance costs; 3. Reduced downtime due to seal replacement, thus improving production efficiency; 4. The locking assembly is rotatably connected to the connecting part, which can apply a resisting force to the leak-proof assembly and enhance the sealing effect; 5. The positioning part on the leak-stopping body and the fitting part on the locking body cooperate to ensure that the leak-stopping component and the locking component are installed in an accurate position, further improving the sealing stability.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a leak-proof device for yarn dyeing racks, see [link]. Figure 1The system includes a dyeing rack 1, a liquid-conducting pipe 2, and a leak-proof mechanism. One end of the liquid-conducting pipe 2 is fixedly connected to the dyeing rack 1. One end of a connecting support rod 11 on the dyeing rack 1 is fixedly connected to the dyeing rack 1, and the other end passes through the liquid-conducting pipe 2. The leak-proof mechanism includes a leak-proof component 3 and a locking component 4. The leak-proof component 3 and the locking component 4 are sequentially fitted onto the connecting support rod 11. The leak-proof component 3 abuts against one end of the liquid-conducting pipe 2, and one end of the locking component 4 abuts against the leak-proof component 3. The locking component 4 is rotatably connected to the connecting support rod 11, thereby enhancing the sealing performance of the connection between the liquid-conducting pipe 2 and the dyeing rack 1 and preventing dye leakage. Through the cooperation of the leak-proof component 3 and the locking component 4, an effective sealing barrier can be formed at the connection, reducing the possibility of dye leakage from gaps.

[0027] Specifically, the connecting rod 11 has a first sleeve 110 and a second sleeve 111. The diameter of the first sleeve 110 is larger than that of the second sleeve 111, and the surface of the first sleeve 110 is smooth. The leak-stopping component 3 is fitted onto the first sleeve 110, and the locking component 4 is rotatably connected to the second sleeve 111. The first sleeve 110 is a smooth metal rod with a polished surface, which ensures that the leak-stopping component 3 slides smoothly on it and that the first sleeve 110 is not prone to rusting. The second sleeve 111 is a rod with external threads. The threads facilitate the rotatable connection of the locking component 4 to it, locking the leak-stopping component 3. The larger diameter of the first sleeve 110 provides sufficient support area for the leak-stopping component 3, while the smooth surface facilitates the installation and movement of the leak-stopping component 3. The threaded structure of the second sleeve 111 enables the stable rotation and positioning of the locking component 4 and locks the leak-stopping component 3.

[0028] Specifically, the leak-stopping component 3 includes a leak-stopping body 31, which is fitted onto the first sleeve 110. The leak-stopping body 31 is specifically a ring-shaped structure made of metal, which has good wear resistance and corrosion resistance.

[0029] The leak-stopping body 31 has a first receiving portion 32 and a second receiving portion 34. The first receiving portion 32 is located near the liquid-conducting pipe 2, and the second receiving portion 34 is located on the middle part of the leak-stopping body 31 and away from the liquid-conducting pipe 2. A first sealing portion 33 is embedded in the first receiving portion 32, which abuts against the liquid-conducting pipe 2 and covers the first sleeve portion 110. A second sealing portion 35 is embedded in the second receiving portion 34, which covers the first sleeve portion 110.

[0030] The first receiving portion 32 is specifically a first annular groove formed on the leak-stopping body 31, the size and shape of which are designed according to the size and shape of the first sealing portion 33. The second receiving portion 34 is specifically a second annular groove formed in the middle of the leak-stopping body 31 for placing the second sealing portion 35, the size and shape of which are designed according to the size and shape of the second sealing portion 35.

[0031] The first sealing part 33 includes a first sealing ring, which is specifically a sealing ring made of fluororubber. The second sealing part 35 includes a second sealing ring, which is specifically a sealing ring made of fluororubber. By using a sealing ring made of fluororubber, the good corrosion resistance, high temperature resistance, and elasticity of the sealing ring can reduce the possibility of dye leakage from gaps.

[0032] The leak-stopping body 31 has a third receiving portion 36, which is located near the locking assembly 4; a third sealing portion 37 is embedded in the third receiving portion 36, which wraps around the first sleeve portion 110.

[0033] The third receiving portion 36 is specifically a third annular groove formed on the leak-stopping body 31. The size and shape of the third annular groove are designed according to the size and shape of the first sealing portion 33. The third sealing portion 37 includes a third sealing ring, which is also a sealing ring made of fluororubber.

[0034] Furthermore, the leak-stopping body 31 includes a main body, an upper cover, and a lower cover. The upper cover fits onto the third receiving portion 36 and is fixedly connected to the main body by bolts. The lower cover fits onto the first receiving portion 32 and is fixedly connected to the main body by bolts.

[0035] Specifically, an arc-shaped through groove is also provided on the lower cover. The first sealing part 33 protrudes to form a convex part that matches the arc-shaped through groove. The convex part is integrally formed with the first sealing part 33. The convex part is used to increase the friction between the leak-proof component 3 and the yarn package sleeved on the liquid pipe 2, and reduce the shaking or displacement of the yarn package during the dyeing process, which affects the dyeing quality.

[0036] Furthermore, the locking assembly 4 includes a locking body 41, which is fitted onto the second sleeve 111 and rotatably connected to it. The third sealing part 37 has a conical part 370, which is inserted into the locking body 41. The leak-proof body 31 has a positioning part 38, and the locking body 41 has a fitting part 42, which is inserted into the positioning part 38. The locking body 41 has a force-bearing part 43, which is integrally formed with the locking body 41.

[0037] Specifically, the locking body 41 is a metal ring with internal threads, which has high strength and wear resistance. The internal thread of the locking body 41 matches the external thread of the second sleeve 111. By rotating the locking body 41, it can be moved on the second sleeve 111 and locked to lock the leak-proof assembly 3.

[0038] The conical portion 370 is specifically a conical ring body integrally formed with the third sealing ring. The conical portion 370 is inserted into the locking body 41, which can make the connection between the third sealing portion 37 and the locking body 41 tighter. When the locking body 41 applies pressure to the third sealing portion 37, the conical portion 370 can deform better, fill the gap between the two, and enhance the sealing effect.

[0039] The positioning part 38 is specifically an annular groove formed on the outer surface of the leak-stopping body 31, and the fitting part 42 is specifically an annular protrusion on the locking body 41. The fitting part 42 is inserted into the positioning part 38 to ensure accurate alignment between the locking body 41 and the leak-stopping body 31, preventing relative displacement between the two during use and affecting the sealing effect.

[0040] The force-bearing part 43 is specifically a ring handle welded to the outer surface of the locking body 41, which facilitates the operator to rotate the locking body 41 to lock or loosen the leak-stopping body 31. The ring handle is ergonomically designed for easy gripping and application of force.

[0041] The working principle of the leak-proof device for yarn dyeing racks in this application is as follows: The liquid-passing tube 2 is fixed by the connecting support rod 11 of the dyeing rack 1. The support rod is divided into a smooth first sleeve 110 with a larger diameter and a second sleeve 111 with external threads. The leak-proof component 3 is fitted onto the first sleeve 110, and the locking component 4 is threadedly connected to the second sleeve 111. By rotating the locking body 41, it moves along the second sleeve 111 and squeezes the leak-proof component 3, so that the first sealing part 33 tightly abuts against the liquid-passing tube 2. At the same time, the second and third sealing parts 37 wrap around the first sleeve 110 to form a multi-layer barrier. The upper and lower covers of the leak-proof body 31 are fixed with sealing rings by bolts. The arc-shaped groove of the lower cover and the protrusion of the sealing ring increase the friction with the yarn package. The fitting part 42 of the locking body 41 cooperates with the positioning part 38 of the leak-proof body 31 to prevent relative displacement. The conical part 370 deforms and fills the gap when under pressure, further enhancing the sealing effect.

[0042] In this technical solution, the corrosion resistance and elasticity of the fluororubber sealing ring ensure long-term sealing performance. The metal leak-stopping body 31 and locking body 41 provide high-strength support and reduce wear. The multi-layer sealing design, with three sealing rings and a tapered portion 370° deformation, forms redundant protection. The positioning structure and threaded locking mechanism prevent loosening and adapt to vibrations during the dyeing process. The lower cover protrusion reduces yarn bobbin misalignment and improves dyeing quality. Compared to traditional sealing methods, this technical solution significantly extends the lifespan of the sealing components and reduces maintenance frequency.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
