Detailed implementation manners
[0028] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings.
[0029] According to the specific implementation manners of the present disclosure, an anhydrous dyeing sarong connection structure is provided, wherein, Figures 1 to 5 One of the specific implementation manners is shown.
[0030] Specifically, referring to Figures 1 to 5 as shown, this anhydrous dyeing sarong connection structure is used for a dyeing kettle 4, and the dyeing kettle 4 includes a kettle lid 41 and a kettle body 42. This sarong connection structure includes a cage body 1, a limiting plate 2 and a limiting cylinder 3. Specifically, the limiting plate 2 is arranged at the top of the cage body 1 to limit the eccentric deflection of the sarong and help the sarong to be centered when placed. The limiting cylinder 3 is arranged at the bottom of the cage body 1; wherein, the limiting cylinder 3 includes a stop section 31 and a sealing section 32 connected to the stop section 31, the diameter of the stop section 31 is larger than that of the sealing section 32, and the stop section 31 is located on the side close to the cage body 1. A chamber 43 for accommodating the cage body 1 is provided in the kettle body 42, the cage body 1 is arranged in the chamber 43, the kettle lid 41 is arranged above the kettle body 42 and presses against the cage body 1; a connecting pipe 6 is provided at the lower end of the kettle body 42, and a limiting hole 61 adapted to the sealing section 32 is provided on the connecting pipe 6, the sealing section 32 is hermetically inserted into the limiting hole 61, and the stop section 31 abuts against the top surface of the connecting pipe 6, thereby limiting the downward movement of the sarong.
[0031] The cage body 1 holds the yarn or fabric to be dyed. The limiting plate 2 is arranged at the top of the cage body 1, which can strengthen the structure of the cage body 1, prevent the yarn from escaping or serve as the contact surface with the top cover of the dyeing kettle 4. The limiting cylinder 3 is located at the bottom of the cage body 1 and is composed of a stop section 31 and a sealing section 32. The difference in the diameters of the two is ingeniously designed, which not only realizes the limiting function but also ensures the sealing performance.
[0032] The stop section 31 has a larger diameter and is located closer to the cage body 1. It is used to abut against the top surface of the connecting pipe 6 when the yarn cage is inserted into the dyeing kettle 4, preventing the yarn cage from moving further downward. The sealing section 32 has a smaller diameter and is closely fitted with the limiting hole 61 of the dyeing kettle 4 to achieve a sealing effect and prevent the leakage of the dyeing liquid or steam.
[0033] A chamber 43 is provided in the kettle cover 41 to accommodate the yarn cage, and preliminary limiting is achieved by pressing against the top of the yarn cage. A limiting hole 61 adapted to the sealing section 32 is provided on the connecting pipe 6 at the lower end of the kettle body 42 to ensure that the yarn cage can be accurately and stably inserted and sealed.
[0034] Through the above technical solution, through the direct insertion connection method, the leakage of the dyeing medium during the dyeing process is effectively prevented, ensuring the dyeing effect and production safety. The connection structure of the yarn cage avoids the complex sealing structure design, has the characteristics of simple structure and convenient operation, makes the installation and disassembly of the yarn cage simple and fast, and improves the production efficiency. Among them, the design of the stop section 31 ensures that the yarn cage will not move excessively downward due to external forces during the dyeing process, ensuring the uniformity and stability of dyeing.
[0035] In an embodiment provided by the present disclosure, refer to Figures 2 to 4 As shown, the sealing section 32 is provided with a sealing structure, which includes an end cover 51 and a sealing ring 52; wherein, a step is formed on the outer periphery of the sealing section 32, the end cover 51 is connected to the end of the sealing section 32, and the end cover 51 abuts against the bottom surface of the sealing section 32, and the inner wall surface of the end cover 51 is flush with the inner wall surface of the sealing section 32; wherein, there is a gap 53 between the top surface of the end cover 51 and the bottom surface of the step, and the sealing ring 52 is sleeved on the outer periphery of the sealing section 32 and embedded in the gap 53.
[0036] The end cap 51 presses against the bottom surface of the sealing section 32, which can increase the sealing tightness and prevent the dyeing medium from leaking from the bottom. The inner wall surface of the end cap 51 is flush with the inner wall surface of the sealing section 32, which not only helps to maintain the smooth flow of the dyeing medium but also reduces the eddy current and resistance generated by the structural mutation. A step is formed on the outer periphery of the sealing section 32, providing a positioning and fixing space for the installation of the sealing ring 52. There is a gap 53 between the top surface of the end cap 51 and the bottom surface of the step, which can be used to embed the sealing ring 52, ensuring that the sealing ring 52 can be fully deformed and fill the gap 53 under pressure, thereby achieving a better sealing effect. The sealing ring 52 is sleeved on the outer periphery of the sealing section 32 and embedded in the gap 53, and adapts to different sealing surface shapes and size changes through its elasticity and deformation ability, ensuring the reliability and durability of the seal.
[0037] Through the dual effects of the end cap 51 and the sealing ring 52, the sealing performance of the sealing section 32 can be greatly improved, preventing the leakage of the dyeing medium, and ensuring the dyeing effect and production safety. The tight connection between the end cap 51 and the sealing section 32 and the embedding of the sealing ring 52 in the gap 53 make the entire sealing structure more stable and reliable, capable of withstanding certain pressure and temperature changes without easy failure. When the sealing ring 52 is worn or aged, it can be conveniently removed from the gap 53 and replaced with a new sealing ring 52, reducing the maintenance cost and downtime.
[0038] In a possible design, referring to Figure 3 as shown, the end cap 51 is provided with a counterbore, and the sealing section 32 is provided with a threaded hole corresponding to the counterbore; the yarn cage connection structure further includes a fastening screw 54 adapted to the threaded hole, and the fastening screw 54 is inserted into the counterbore and the threaded hole to maintain the position of the end cap 51 relative to the sealing section 32.
[0039] The setting of the counterbore on the end cap 51 enables the head of the fastening screw 54 to be completely sunk into the hole, avoiding the possible obstruction caused by the protrusion of the screw head from the surface of the end cap 51. A threaded hole is provided at a position corresponding to the counterbore on the sealing section 32 for receiving the fastening screw 54, and the end cap 51 and the sealing section 32 are fastened through threaded connection.
[0040] The fastening screw 54 is inserted into the counterbore and the threaded hole, and the screw is rotated to be threadedly engaged with the threaded hole, thereby realizing the fastening connection between the end cap 51 and the sealing section 32. The fastening screw 54 not only plays a connecting role but also maintains the position of the end cap 51 relative to the sealing section 32 through its fastening force, preventing the end cap 51 from loosening or shifting due to external forces during use and preventing leakage problems caused by loose connection.
[0041] The tightening force of the fastening screw 54 enables the end cover 51 to be tightly pressed against the bottom surface of the sealing section 32, further enhancing the sealing effect and ensuring the sealing during the dyeing process. In addition, the installation and removal of the fastening screw 54 are also relatively simple and quick, which is convenient for maintenance and replacement when necessary.
[0042] In one possible design, see Figure 4 As shown, the inner wall of the end cap 51 is provided with an internal thread, the outer periphery of the sealing section 32 is provided with an external thread matching the internal thread, and the end cap 51 is threadedly connected to the sealing section 32. This design allows the yarn cage to be easily placed and taken out, and has good sealing performance, and can use sealing materials with high hardness, and the durability of the sealing structure is better. The structure is simpler than the central rod series structure, with fewer leakage points, which can prevent the screws from falling into the pipeline and damaging the pump valve after loosening.
[0043] When making a connection, the end cap 51 is rotated so that the internal thread and the external thread can be tightly engaged together, thereby connecting the end cap 51 to the sealing section 32 through threads, making the connection more secure and reliable. Since the threaded connection has a self-locking property, once the end cap 51 and the sealing section 32 are tightly connected through threads, they can withstand a large tensile force and torque, thereby ensuring the stability of the connection. When disassembly is required, the end cap 51 can be easily separated by rotating it in the opposite direction without the use of special tools, thereby improving the convenience of maintenance.
[0044] Specifically, the bottom corners of the end cap 51 are formed into rounded corners or beveled corners. This design can make the bottom corners of the end cap 51 transition smoothly without sharp right angles, which can more easily guide the alignment of components and reduce assembly difficulties or damage caused by sharp corners.
[0045] In an embodiment provided in the present disclosure, the limiting hole 61 includes a guide section 611, a straight section 612, a contraction section 613 and a connecting section 614 which are arranged in sequence. The guide section 611 is formed with an outwardly expanded chamfer, and the diameter of the contraction section 613 gradually decreases along the direction of the straight section 612.
[0046] The guide section 611 is the starting part of the limiting hole 61, and its outwardly expanded chamfered structure is beneficial to guiding the sealing section 32 to be inserted; the straight section 612 provides a stable initial channel, so that the sealing section 32 can smoothly enter and keep moving in a certain direction, avoiding deflection or shaking when entering the limiting hole 61. The diameter of the contraction section 613 gradually decreases, helping the insert to transition to the contraction section 613 more smoothly. The pipe section 614 is the end part of the limiting hole 61, and has a smaller diameter, which is convenient for inserting other auxiliary pipes.
[0047] Specifically, a sealing ring 52 is provided on the sealing section 32 to ensure the sealing between the end cover 51 and the sealing section 32, thereby preventing leakage of the dyeing medium. The distance from the sealing ring 52 to the guide section 611 is greater than the distance from the top of the gauze cage to the kettle cover 41. When the dyeing medium enters the gauze cage from the bottom, the gauze cage will move toward the dyeing kettle cover 41 due to the great resistance of the dyeing fabric passing through the gauze cage. When the gauze cage reaches the dyeing kettle cover 41, it will be blocked by the dyeing kettle cover 41, so that it will no longer move outward. At this time, the sealing ring 52 at the bottom is still located in the limiting hole 61 of the end pipe 6 to play a sealing role.
[0048] In one embodiment provided by the present disclosure, a perforated tube 7 having a plurality of air holes is provided in the cage body 1, and the axis of the perforated tube 7 is parallel to the axis of the cage body 1. The air holes on the perforated tube 7 allow gas to flow, thereby completing the gas dredging (exhaust and intake) work. The perforated tube 7 is arranged vertically, which is convenient for installation and is also beneficial for smooth and uniform gas flow.
[0049] Specifically, the air holes are provided in a plurality and evenly distributed on the hole tube 7, so that the air flows more evenly. One end of the hole tube 7 is connected to the connecting pipe 6, and the other end is set as a closed structure, which can help the article to be dyed evenly. In addition, the number of the hole tubes can be one or more, and the present disclosure does not limit this.
[0050] In the present disclosure, the gauze cage can be used for dyeing wool, dyeing cheese yarn, dyeing fabrics and other different items. Therefore, the specific structure of the cage body 1 is determined by the specific dyeing fabric. In this regard, those skilled in the art can flexibly configure it according to actual processing requirements.
[0051] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
