Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, specifically relating to a steaming device for fine wool spinning production. Background Technology

[0002] Unlike other fibers, wool fibers possess excellent crimp properties. During production, they are lengthened through combing and drafting, resulting in significant internal stress. If this stress is not promptly eliminated, it increases the difficulty of weaving, making it challenging to stabilize certain physical properties and appearance of the product, thus failing to meet design requirements. Years of research tracking the quality and production process of worsted wool products have revealed that selective steaming of the slivers, rovings, yarns, and ply yarns after processing can quickly and efficiently eliminate internal stress imbalances and static electricity, improve moisture regain, and significantly shorten the production cycle. Furthermore, the timely opening and recombination of disulfide bonds within the fibers helps ensure and improve product quality, enabling companies to adapt to the market's trend towards multi-variety, small-batch production with short delivery times.

[0003] The proper selection of the steaming process can not only improve the quality of yarn and the finished fabric, but also reduce the yarn storage period, thus shortening the delivery time. Domestically, steaming methods generally employ wet heat setting and dry heat setting, but traditional steaming methods and equipment have certain drawbacks. After steaming, the yarn performance decreases, resulting in garments that are not soft and comfortable enough. Internationally, highly automated electrically heated steaming boxes are generally used. While these boxes allow for arbitrary setting of temperature, time, and humidity, automatically controlling the entire wet heat setting process, a drawback is that uneven airflow within the steaming box can easily lead to uneven yarn twist and strength.

[0004] Existing technology, such as the patent announcement document CN112176589B, discloses a wool yarn steam setting system, including a setting chamber, a vacuum pump for extracting air from the setting chamber, a steam tank for storing steam, and a cargo vehicle for transporting items to be set. The output end of the steam tank includes a first delivery pipe and a second delivery pipe. The second delivery pipe is used to supply steam to a steam drive device. The cargo vehicle carries a rotating bracket that is rotatably connected to the cargo vehicle. The front end of the rotating bracket is provided with a plug-in shaft. The output end of the steam drive device is provided with an output groove at the position where it mates with the plug-in shaft. When the plug-in shaft is inserted into the output groove, the steam drive device can drive the rotating bracket on the cargo vehicle to rotate.

[0005] The problems with the existing technology include: before the device works, the yarn to be shaped needs to be wound around the carrier rod and then pushed into the shaping chamber. This requires manual winding or the use of an external feeding device, resulting in low work efficiency. Summary of the Invention

[0006] To address the aforementioned problems, the purpose of this invention is to provide a steaming device for fine wool spinning production. This device simultaneously achieves the dual objectives of yarn feeding and steam setting within a single unit. It eliminates the need for an internal motor, utilizing only the steam used for steaming as its power source.

[0037] Example 1

[0038] As attached Figure 1 As shown, the present invention provides a steaming device for fine wool spinning production, including a setting chamber 1, a steam tank 2, a steam drive structure 3 connected to the output pipe of the steam tank 2, a feeding cart 4, and a feeding structure 5 disposed on the feeding cart 4.

[0039] In this embodiment, as shown in the appendix Figure 2 As shown, the shaping chamber 1 includes a chamber body 101, a chamber door 102 disposed on the side of the chamber body 101 near the second chassis 502, an extension frame 103 disposed on the side of the chamber body 101 near the chamber door 102, a feeding roller 104 disposed on the extension frame 103 and located at the upper end of the chamber door 102, and a wire inlet hole 105 disposed on the chamber door 102. In addition, a stop structure is provided at the bottom of the shaping chamber 1. At least two wire inlets 105 are provided, corresponding to small-diameter winding and large-diameter winding modes respectively, and the positions of the wire inlets 105 are radially located outside the outer periphery of the winding to ensure continuous winding without problems such as wire jamming.

[0040] In this embodiment, as shown in the appendix Figure 2 As shown, the output pipe of the steam tank 2 includes a main pipe 201, a first conveying pipe 202 connected to the bottom of the shaping chamber 1, a second conveying pipe 203 extending into the shaping chamber 1 and used to supply steam to the steam drive structure 3, and a third conveying pipe 204 connected to the top of the shaping chamber 1. Valves 205 are provided on both the first and third conveying pipes 202 and 204. The steam tank 2 stores steam. Multiple steam outlets can be correspondingly opened on the inner wall of the chamber 101, evenly distributed above the feeding structure 5, ensuring uniform steam output. The individual valves 205 on the first and third conveying pipes 202 and 204 are configured to control their opening and closing to align with the process flow of this device. During the winding stage, valves 205 are closed, and steam from the steam tank 2 is individually delivered to the steam drive structure 3 to drive the feeding structure 5 to rotate. During the shaping stage, valves 205 are opened, all pipes are opened, and steam is delivered to the steam drive structure 3 and the chamber 101 respectively.

[0041] In this embodiment, the steam-driven structure 3 is mentioned, but its internal structure is not substantially required. The steam-driven structure 3 is existing technology that those skilled in the art can conceive of, and therefore will not be described in detail here. This embodiment only limits the output end of the steam-driven structure 3 to a polygonal columnar groove, capable of docking with the front end of the rotating shaft 508 described below. It is understood that the output end of the steam-driven structure 3 can also be a polygonal prism, and the front end of the corresponding rotating shaft 508 can be replaced with an insertion groove. It is understood that the steam-driven structure 3 can be located inside or outside the hopper 101, relying solely on its output end entering the hopper 101 and slowly rotating to drive the feeding structure 5 to rotate. The sealing technology connecting the output end to the hopper 101 is existing technology that those skilled in the art can obtain, and therefore will not be described further.

[0042] In this embodiment, as shown in the appendix Figure 3As shown, the loading trolley 4 includes a base plate 401, two fixed vertical plates 402 disposed at both ends of the base plate 401, a stop 403 disposed on the lower surface of the base plate 401 and cooperating with the stop structure to limit the moving end point of the loading trolley 4, a pulley 404 disposed at the lower end of the base plate 401, and a handle 405 disposed on the side end of the base plate 401.

[0043] In this embodiment, as shown in the appendix Figure 3 Appendix Figures 5-7 As shown, the feeding structure 5 includes a first base plate 501 and a second base plate 502 located between and rotatably connected to the two fixed vertical plates 402, a connecting screw 503 disposed on the second base plate 502, at least two first connecting rods 504 disposed between the first base plate 501 and the second base plate 502 and located on the outer periphery of the connecting screw 503, a first sliding ring 505 sleeved on the outer side of all the first connecting rods 504, and a plurality of limiting rods 504 radially disposed on the inner wall of the first sliding ring 505. 06. An internally threaded ring 507 screwed onto the outside of the connecting screw 503 and connected to the limiting rod 506, and a rotating shaft 508 disposed on the side end of the first chassis 501, passing through the fixed vertical plate 402 and connected to the output end of the steam drive structure 3, and located on the same axis as the connecting screw 503; wherein, the gap between two adjacent limiting rods 506 is used for the passage of the first connecting rod 504, and the length of the connecting screw 503 is 1 / 2 to 2 / 3 of the length of the first connecting rod 504 or the second connecting rod 509.

[0044] It is worth noting that the first chassis 501 and the second chassis 502 are of the same size. The first chassis 501 is directly connected to the output end of the steam drive structure 3 via a rotating shaft 508. A rotating ring is provided at the connection between the rotating shaft 508 and the fixed vertical plate 402 to ensure that the rotating shaft 508 and the fixed vertical plate 402 are rotatably connected. A connecting shaft 502b is provided at the center of the side end of the second chassis 502 away from the first chassis 501 and is rotatably connected to the fixed vertical plate 402. The rotating shaft 508 and the connecting shaft 502b are located on the same axis to ensure that the first chassis 501 and the second chassis 502 rotate synchronously. The second chassis 502 is provided with a wire hole 502a located outside the insertion hole 512 described below. A groove 503c is provided at the center of the surface of the second chassis 502 opposite to the surface where the connecting shaft 502b is installed for installing the connecting screw 503 to ensure that the connecting screw 503 rotates synchronously under the drive of the second chassis 502.

[0045] It is worth noting that the first chassis 501 and the second chassis 502 are provided with corresponding circumferentially distributed insertion holes 512. The two ends of the first connecting rod 504 pass through the insertion holes 512 on the first chassis 501 and the second chassis 502 to achieve fixation. The number of insertion holes 512 is set according to actual needs. The first connecting rod 504 does not need to fill all the insertion holes 512. It is sufficient to install at least two first connecting rods 504 with sufficient spacing to complete the installation of the feeding structure. When all the insertion holes 512 are filled with first connecting rods 504, all the first connecting rods 504 are parallel to each other and form a winding frame with a circular outer periphery. When winding yarn, the yarn is wound on the outer periphery of all the first connecting rods 504.

[0046] As attached Figure 9 As shown, when one end of yarn a enters the feeding structure 5 and is fixed at the position closest to the first base plate 501 on the first connecting rod 504, the unwound yarn passes completely through the entire winding frame formed by the first connecting rod 504. When the winding frame is rotated, because the unwinding point is located at the rear end (second base plate), the number of loops wound on yarn a at the front end (first base plate) is extremely small. As the loops get closer to the unwinding point, their number increases significantly compared to the front end. This winding situation not only fails to fully utilize the entire winding frame, resulting in a limited length of yarn wound in one operation and low efficiency, but also leads to uneven distribution of the wound loops, resulting in uneven setting effect.

[0047] Therefore, this device is equipped with a first sliding ring 505, which is mainly used for uniform coil distribution. It can slide from the rear end to the front end. Since the ring is located on the outer periphery of the first connecting rod 504, the ring can push the coil at its front end to move forward together, thereby shortening the distance between the front coils. Specifically, the sliding of the first sliding ring 505 from front to back is achieved by the connecting screw 503. When the connecting screw 503 rotates together with the second chassis 502, the rotation of the thread on the screw drives the internal thread ring 507 to rotate. The limiting rod 506, which connects the internal thread ring 507 and the first sliding ring 505, is locked in the circumferential direction because it passes through the first connecting rod 504. Therefore, when the connecting screw 503 rotates, the internal thread ring 507 is driven to move on the connecting screw 503, thereby driving the first sliding ring 505 to slide from back to front on the outer circumference of the winding frame formed by the first connecting rod 504, until the internal thread ring 507 moves to the farthest end of the connecting screw 503. At this time, the connecting screw 503 continues to rotate, and the position of the first sliding ring 505 remains unchanged. Therefore, after the first sliding ring 505 plays its role, the finally wound coil is as shown in the attached figure. Figure 10As shown, with the increase in the number of front-end coils, although the coil arrangement will become loose again at the rear end of the first sliding ring 505, the spacing is within an acceptable range because it is close to the yarn feeding end. Finally, after the yarn completes the winding of the entire winding frame, the uniformity of its distribution is significantly improved, and the number of wound coils is significantly increased, which helps to improve work efficiency and shaping effect.

[0048] The steaming device provided in this embodiment has the following advantages compared to the prior art: First, it can independently achieve yarn winding and feeding as well as steaming and setting effects. Moreover, the device does not require an internal motor and only uses steam for steaming as a power source, which has the advantages of high working efficiency, high safety, and strong economy. Second, the optimized winding and feeding method ensures that the yarn distribution is fully and evenly distributed, further improving working efficiency and setting effect.

[0049] In this embodiment, as shown in the appendix Figure 4 and attached Figure 8 As shown, the feeding structure 5 also includes a larger winding frame structure, comprising a plurality of second connecting rods 509 arranged circumferentially between the first base 501 and the second base 502 and located outside the first connecting rod 504; a second sliding ring 510 sleeved on the outside of all the second connecting rods 509; and a connecting strip 511 disposed on the inner wall of the second sliding ring 510 and connected to the outer wall of the first sliding ring 505. The ends of the second connecting rods 509 and the first connecting rods 504 are the same size, and the first base 501 and the second base 502 are respectively provided with insertion holes 512 for the ends of the second connecting rods 509 to pass through. The working principle and structure of this frame structure are roughly the same as those described above, so they will not be repeated here. Understandably, when a small-sized frame is required, the first sliding ring 505 and its related connecting structures can be used alone. However, when a large-sized frame is required, the first sliding ring 505 and its related connecting structures, along with the second sliding ring 510 and other structures, must all be present. In this case, the first sliding ring 505 and its related structures are used to drive the second sliding ring 510 to slide on the larger frame, thereby pushing the coil to move, and do not perform the function of pushing the coil. Understandably, the second sliding ring 510 can also exist independently of the first sliding ring 505. In this case, the second sliding ring 510 is directly connected to the internal threaded ring 507 through the connecting bar 511, and the gap between two adjacent connecting bars 511 of the second connecting rod 509 is used to limit and lock the circumferential rotation of the second sliding ring 510.

[0050] In this embodiment, in order to facilitate the sliding of the coil on the frame and to facilitate the removal of the yarn after the shaping is completed, a drag-reducing layer 513 is provided on the outer peripheral surface of the first connecting rod 504 and the second connecting rod 509. The material of the drag-reducing layer can be any low friction coefficient material that is resistant to high temperature and high humidity, such as polytetrafluoroethylene.

[0051] The working principle of this device, taking the first connecting rod 504 as the winding frame as an example, is as follows: The feeding structure 5 is installed on the feeding carriage 4, which is located at the outer end of the bin 101. The feeding carriage 4 is pushed to the entrance of the bin 101, and the yarn end on the feeding roller 104 is passed through the inlet hole 105 on the bin door 102 and fixed to the first connecting rod 504 near the first chassis 501. Then, the entire feeding carriage is pushed into the bin 101, and the connecting shaft 508 is inserted into the output end of the steam drive structure 3, so that the steam drive structure 3 can drive the feeding structure to rotate. When the feeding trolley 4 reaches the predetermined position of the stop 403, the hopper door 102 is closed; all valves 205 are closed, and the steam tank 2 is started to supply steam to the steam drive structure 3, thereby driving the feeding structure 5 to rotate. Yarn a begins to wind on the frame, and the first sliding ring 505 helps to distribute the winding coils evenly. When the first sliding ring 505 moves to the limit position, the yarn located on the outside of the hopper is cut off, the valve 205 is opened, and the feeding structure 5 continues to drive the entire frame to rotate and continue to wind the excess yarn. The hopper 101 is filled with steam, which shapes all the yarns on the feeding structure 5. After the shaping is completed, open the hopper door 102 and move the loading trolley 4 and the loading structure 5 out of the hopper body 101. First, remove the first connecting rod 504, then unscrew the first sliding ring 505 from the end of the connecting screw 503. Remove the first sliding ring 505 together with the shaped coil from the loading trolley. Finally, remove the first sliding ring 505 from the coil to obtain the shaped yarn product.

[0052] It is worth noting that the chamber 101 can also be equipped with a vacuum pump to achieve a suitable vacuum level inside the chamber 101, thereby further improving the shaping effect. The structure of the vacuum pump and the sealing structure of the chamber 101 can refer to existing technologies, so they will not be described in detail here.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
