Description

Technical Field

[0001] This utility model relates to the field of cashmere yarn technology, specifically to a dyeing vat for reactive cashmere yarn. Background Technology

[0002] In the cone dyeing process of reactive cashmere yarn, the dyeing rods are usually fixed on the distribution coils at the bottom of the dyeing vat. Existing connection methods mostly use clamp structures. This traditional connection structure has a significant bottleneck in disassembly and assembly efficiency: each time a dyeing batch is changed, workers need to loosen, disassemble, clean, reassemble, and tighten each dyeing rod individually. This is not only labor-intensive and extremely time-consuming (a single rod change often takes more than 30 minutes), but also, cashmere fibers are extremely delicate, and excessive downtime can cause the yarn to remain in a humid environment, increasing the risk of fiber damage and pilling.

[0003] Based on the above, this utility model proposes a dyeing vat for reactive cashmere yarn, which can effectively solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a dyeing vat for reactive cashmere yarn, which solves the defects and deficiencies of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A dyeing vat for reactive cashmere yarn includes a vat body and a dye liquor circulation pipeline located at the bottom of the vat body. The interior of the vat body is connected to the external circulation supply equipment through the dye liquor circulation pipeline. The bottom of the cylinder is provided with an annular coil, and the top of the annular coil is fixed with a diverter end. The diverter end is detachably connected to the dyeing rod through a quick-release sealing unit. The quick-release sealing unit includes a quick-release head and a quick-release seat, and a sealing ring is provided between the quick-release head and the quick-release seat. The quick-release head is fixed with a lower locking tooth block on its outer side, and multiple lower locking teeth blocks are evenly distributed along the circumference of the quick-release head. The quick-release base has an inner cavity that is adapted to the quick-release head, and an upper locking tooth block is fixed in the cavity. A misalignment gap is formed between adjacent upper locking teeth, and the upper locking teeth correspond to the misalignment gap.

[0006] This invention relates to a dyeing vat for reactive cashmere yarn. It utilizes a toothed locking mechanism between the lower locking teeth on the quick-release head and the upper locking teeth in the quick-release seat. Simply align the quick-release seat with the misalignment gap, insert it, and then rotate it slightly to achieve rigid locking using the locking plane. Compared to traditional bolt fastening methods, this significantly reduces the assembly and disassembly time for a single dyeing bar, substantially shortening non-production waiting time.

[0007] Preferably, the top of the upper locking tooth block has an abutting ramp and a locking plane, and rotating the upper locking tooth block of the quick-release seat can make it abut and lock against the lower locking tooth block above it.

[0008] Preferably, the dyeing rod includes a dyeing rod body that is connected and communicates with the top of the quick-release seat, and both ends of the dyeing rod body are provided with limiting discs.

[0009] Preferably, a limit block is fixed on the side of the upper locking tooth block near the locking plane.

[0010] This invention provides a dyeing vat for reactive cashmere yarn. It has the following beneficial effects: 1. This utility model relates to a dyeing vat for reactive cashmere yarn. It utilizes a toothed engagement locking mechanism between the lower locking teeth on the quick-release head and the upper locking teeth in the quick-release seat. Simply align the quick-release seat with the misalignment gap, insert it, and then rotate it slightly to achieve rigid locking using the locking plane. Compared to traditional bolt fastening methods, the assembly and disassembly time for a single dyeing bar is significantly reduced, substantially shortening non-production waiting time.

[0011] 2. During the rotation locking process, the upper locking tooth block slides down along the abutting inclined surface of the lower locking tooth block, automatically pressing the quick-release head towards the quick-release seat, thereby automatically tightening the middle sealing ring. This structure converts the "rotational action" into "axial clamping force," achieving effective clamping and sealing at the sealing ring. At the same time, the continuous elastic support force generated by the sealing ring can reverse the relative abutting friction between the upper and lower locking tooth blocks of the bracket, thus ensuring stability in the locked state.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figures 1-7 As shown, this utility model embodiment provides a dyeing vat for reactive cashmere yarn, including a vat body 1 and a dye liquor circulation pipe 2 disposed at the bottom of the vat body 1. The interior of the vat body 1 is connected to the external circulation supply equipment through the dye liquor circulation pipe 2. The bottom of the cylinder 1 is provided with an annular coil 11, and the top of the annular coil 11 is fixed with a diverter end 12. The diverter end 12 is detachably connected to the dyeing rod 4 through a quick-release sealing unit 3.

[0016] Because the dyeing vat for reactive cashmere yarn of this utility model has the above structure, the annular coil 11 is made of stainless steel 316L, and the inner wall is polished to reduce fluid resistance. Its outer diameter is precisely matched with the inner cavity at the bottom of the vat body 1 to ensure that there are no dead corners when the dye liquor circulates.

[0017] The diverter end 12 is integrally welded to the annular coil 11 and internally interconnected. This structure allows the dye liquor to be evenly distributed to each dyeing bar 4 after entering from the dye liquor circulation pipeline 2, avoiding local flow velocity differences caused by uneven flow channels, thereby improving the evenness of cashmere yarn dyeing. At the same time, the annular coil 11 is connected to the bottom of the cylinder 1 by bolt flanges, which facilitates later cleaning and maintenance, and the overall structure does not show significant deformation when subjected to a circulating pressure of 0.6MPa, ensuring long-term operational stability.

[0018] Furthermore, in another embodiment, the quick-release sealing unit 3 includes a quick-release head 31 and a quick-release seat 32, and a sealing ring 33 is provided between the quick-release head 31 and the quick-release seat 32.

[0019] The quick-release head 31 is a cylindrical metal component with an annular groove at the bottom for embedding a sealing ring 33 (preferably fluororubber FKM, which is resistant to temperature 180℃ and chemical corrosion). Its interior is hollow and communicates with the dyeing rod body 41.

[0020] Under pressure, the sealing ring 33 expands radially, filling the microscopic gap between the quick-release head 31 and the quick-release seat 32 to achieve a dynamic seal. Furthermore, the sealing ring 33 is removable and replaceable, avoiding the risk of leakage due to aging. Compared to traditional threaded compression seals, this structure offers faster sealing response and better repeatability, making it particularly suitable for cashmere dyeing scenarios involving frequent disassembly and assembly.

[0021] The quick-release head 31 is fixed with a lower locking tooth block 34 on its outer side, and multiple lower locking tooth blocks 34 are distributed at equal intervals along the circumferential direction of the quick-release head 31.

[0022] Furthermore, in another embodiment, the inner side of the quick-release base 32 has a receiving cavity 35 adapted to the quick-release head 31, and an upper locking tooth block 36 is fixed in the receiving cavity 35.

[0023] A misalignment gap 37 is formed between adjacent upper locking teeth 36, and the upper locking teeth 36 corresponds to the misalignment gap 37.

[0024] Because the dyeing vat for reactive cashmere yarn of this invention has the above structure, the depth of the receiving cavity 35 of the quick-release seat 32 is greater than the height of the quick-release head 31. This gap provides space for the compression deformation of the sealing ring 33, avoiding sealing failure caused by hard contact; the number of upper locking teeth 36 and lower locking teeth 34 are matched. During operation, the upper locking teeth 36 serves as the fixed force-bearing end, and the inclination angle of its contact slope 360 ​​ensures that the downward pressure stroke during rotation is moderate, and that the rotational force is efficiently converted into axial clamping force.

[0025] Furthermore, in another embodiment, the top of the upper locking tooth block 36 has an abutment slope 360 ​​and a locking plane 361, and rotating the upper locking tooth block 36 of the quick-release seat 32 can cause it to abut and lock against the lower locking tooth block 34 above it.

[0026] Because the dyeing vat for reactive cashmere yarn of this utility model has the above structure, the locking plane 361 and the contacting inclined plane 360 ​​are smoothly connected. The locking plane 361 is a horizontal plane and is parallel to and fits against the bottom surface of the lower locking tooth block 34. In the locked state, the contact area between the two accounts for more than 70% of the bottom surface of the tooth block, avoiding tooth block wear caused by point contact or line contact. Meanwhile, the knurling treatment on the surface of the locking plane 361 further enhances the friction in the locked state. During operation, when the quick-release seat 32 rotates until the locking plane 361 is in contact with the bottom surface of the lower locking tooth block 34, the rotational resistance suddenly increases. The worker can directly judge whether the locking is in place by touch. Even if the dye liquor circulation generates high-frequency vibration after locking, the rigid contact of the locking plane 361 can prevent the tooth block from rotating spontaneously.

[0027] Furthermore, in another embodiment, the dyeing rod 4 includes a dyeing rod body 41 connected and in communication with the top of the quick-release seat 32, and both ends of the dyeing rod body 41 are provided with limiting discs 42.

[0028] The dyeing vat for reactive cashmere yarn of this invention has the above structure.

[0029] The limiting plate 42 is disc-shaped and has a diameter larger than that of the dyeing rod 41. It is fixed to both ends of the dyeing rod 41 by interference fit or snap fastener.

[0030] Furthermore, in another embodiment, a limit block 39 is fixed to the side of the upper locking tooth block 36 near the locking plane 361.

[0031] Because the dyeing vat for reactive cashmere yarn of this utility model has the above structure, the dyeing rod 41 is made of 304 stainless steel seamless tube, and micropores are evenly opened on the tube wall. The micropore density gradually increases from the middle to both ends along the axial direction of the rod, which is adapted to the flow distribution characteristics of the annular coil 11 to ensure the uniformity of liquid output of the entire rod. The limiting plate 42 restricts the axial displacement of the cashmere yarn package.

[0032] In use, first place the dyeing rod 4, with the cashmere yarn wound and the limiting discs 42 fixed at both ends, above the cylinder 1. Align the quick-release head 31 at the bottom of the dyeing rod 4 with the misalignment gap 37 of the quick-release seat 32 on the diverter end 12 and insert it vertically. After the quick-release head 31 is completely submerged in the receiving cavity 35, rotate the quick-release seat 32. At this time, the contact slope 360 ​​of the upper locking tooth block 36 will contact the lower locking tooth block 34. Finally, the locking plane 361 and the lower locking tooth block 34 will form a contact lock, thus automatically pressing the sealing ring 33 and using the locking plane 361 and the limiting block 39 to achieve rigid locking. Simultaneously, the sealing ring... The continuous elastic support force generated by 33 can also counteract the relative friction between the upper locking tooth block 36 and the lower locking tooth block 34 on the support, thus ensuring its stability in the locked state. Then, the cylinder cover is closed and the circulating liquid supply equipment is started. The dye liquor enters the dyeing rod body 41 through the dye liquor circulation pipeline 2, the alignment connector 110, the annular coil 11 and the diversion connector end 12, sprays out from the micropores and penetrates the yarn layer to complete the dyeing. After the dyeing is completed, the pressure is released and the cover is opened. The quick release seat 32 can be rotated in the opposite direction to quickly release the lock and pull out the dyeing rod 4 for the next round of operation. No tools are required throughout the process, which greatly shortens the time for changing the rod and reduces the risk of yarn retention and damage.
