Description

Technical Field

[0001] The present disclosure relates to the technical field of yarn steaming equipment, and more precisely, the present disclosure relates to a yarn steaming tube. Background Art

[0002] During the process of processing woolen raw materials into yarns, due to repeated stress and friction, the internal stress is unbalanced and deformation occurs, resulting in fatigue and static electricity. At the same time, after adding twist, the wool yarn has a large untwisting torque, which will affect the subsequent production. After yarn steaming, under the humid heat condition, the connection between fiber macromolecules is relaxed, and then recombined at new positions, thereby eliminating fiber fatigue and static electricity, stabilizing the twist, and preventing the phenomenon of small braid knots from occurring in the subsequent processes.

[0003] The traditional yarn steaming tube used for yarn steaming has a simple cylindrical structure. During the yarn steaming process, the yarn wound around the cylindrical yarn steaming tube is placed in a steam box or steamer to process the yarn. However, in the prior art, due to the action of mechanical tension during the twisting process, the yarn is in a tensioned state after winding, and steaming the yarn in a tensioned state will damage the fiber strength of the yarn.

[0032] The present disclosure provides a yarn steaming tube, which includes a yarn steaming inner tube, yarn steaming sheets, a transmission rod, and a lifting mechanism. At least two yarn steaming sheets are disposed around the outside of the yarn steaming inner tube, and the upper part of the yarn steaming sheet is connected to the yarn steaming inner tube. One end of the transmission rod is connected to the lifting mechanism, and the other end is connected to the lower part of the yarn steaming sheet. During the movement of the lifting mechanism, the transmission rod is driven to move, so as to expand or reset the yarn steaming sheet.

[0033] In the yarn steaming tube provided by the present disclosure, since at least two yarn steaming sheets are disposed around the outside of the yarn steaming inner tube, and the yarn steaming sheets can be expanded or reset under the control of the lifting mechanism, the yarn is wound around the yarn steaming sheets in the expanded state, and then the yarn steaming sheets are reset. At this time, the yarn is in a relaxed state. Performing the yarn steaming operation in this state can effectively avoid the problem of damaging the fiber strength of the yarn during the yarn steaming process.

[0034] For ease of understanding, the following refers to Figure 1, the specific structure and working principle of the yarn steaming tube of the present disclosure will be described in detail in combination with an embodiment.

[0035] The present disclosure provides a yarn steaming tube, including: a yarn steaming inner tube 1, yarn steaming sheets 2, a transmission rod 3, and a lifting mechanism; at least two yarn steaming sheets 2 are provided and are configured to be arranged around the outer side of the yarn steaming inner tube 1; the upper part of the yarn steaming sheet 2 is configured to be connected to the yarn steaming inner tube 1; one end of the transmission rod 3 is connected to the lifting mechanism, and the other end is configured to be connected to the lower part of the yarn steaming sheet 2; the lifting mechanism is configured to drive the transmission rod 3 to move during the movement process, and the transmission rod 3 is configured to drive the yarn steaming sheet 2 to expand or reset during the movement process.

[0036] Specifically, as Figure 1 shown, at least two yarn steaming sheets 2 are arranged around the outer side of the yarn steaming inner tube 1, and the upper part of the yarn steaming sheet 2 is connected to the upper part of the yarn steaming inner tube 1. When the yarn steaming sheet 2 is in the reset state, at least two yarn steaming sheets 2 will present a cylindrical structure sleeved on the outer side of the yarn steaming inner tube 1. The lifting mechanism is a rotating nut 4 sleeved on the yarn steaming inner tube 1 and a thread cooperating with the rotating nut 4. A driven ring 5 is arranged above the rotating nut 4. One end of the transmission rod 3 is connected to the inner wall of the yarn steaming sheet 2, and the other end is connected to the driven ring 5. The driven ring 5 can move along the thread of the yarn steaming inner tube 1 following the rotating nut 4 to achieve the purpose of lifting. Therefore, when the driven ring 5 moves upward, the transmission rod 3 will apply an outward thrust to the yarn steaming sheet 2, and at this time the yarn steaming sheet 2 is expanded. When the driven ring 5 moves downward, the transmission rod 3 will apply an inward pulling force to the yarn steaming sheet 2, and at this time the yarn steaming sheet 2 is reset. Since at least two yarn steaming sheets 2 are provided and are configured to be arranged around the outer side of the yarn steaming inner tube 1, before steaming, the lifting mechanism is used to expand multiple yarn steaming sheets 2 outwards. When the yarn steaming sheets 2 are in the expanded state, the yarn is wound around the outer wall of the yarn steaming sheets 2. After winding, the yarn steaming sheets 2 are appropriately retracted through the lifting mechanism, but not completely reset. At this time, the originally tight yarn will be in a relaxed state, and the yarn wound around the outer periphery of the yarn steaming sheets 2 will not fall off the yarn steaming tube. Adding at least two yarn steaming sheets 2 outside the yarn steaming inner tube 1 can ensure that the yarn is uniformly heated during the heating process, thereby improving the steaming effect; one end of the transmission rod 3 is connected to the lifting mechanism, and the other end is connected to the lower part of the yarn steaming sheet 2. Therefore, during the movement of the lifting mechanism, the state of the yarn steaming sheet 2 can be controlled through the transmission rod 3. When the transmission mechanism moves upward, the yarn steaming sheet 2 moves outward relative to the yarn steaming inner tube 1, and at this time the yarn steaming sheet 2 is expanded; when the transmission mechanism moves downward, the yarn steaming sheet 2 moves inward under the pulling force of the transmission rod 3, and the movement amplitude of the lifting mechanism can be flexibly adjusted manually. Therefore, the movement amplitude of the yarn steaming sheet 2 is also manually controllable. Such a design can not only make the yarn in a relaxed state during the steaming process, thereby preventing the fiber strength of the yarn from being damaged, but also ensure that the yarn is uniformly heated during the heating process, thereby improving the steaming effect.

[0037] In one embodiment of the present disclosure, the lifting mechanism includes a thread provided at the lower part of the inner steam yarn tube 1 and a rotating nut 4 that cooperates with the thread.

[0038] Specifically, as Figure 1 shown, the lifting mechanism includes a thread on the inner steam yarn tube 1 and a rotating nut 4 that cooperates with the thread. The lifting movement is achieved by rotating the rotating nut 4. The lifting of the rotating nut 4 is manually controlled by a wrench adapted to the rotating nut 4. The rotating nut 4 is usually made of wear-resistant material to ensure that it can maintain good fitting accuracy during long-term use. When the rotating nut 4 is manually controlled to rotate counterclockwise, the rotating nut 4 will rise along the thread at the lower part of the inner steam yarn tube 1. When the rotating nut 4 rises, the transmission rod 3 will drive the steam yarn sheet 2 to expand outwards; when the rotating nut 4 is manually controlled to rotate clockwise, the rotating nut 4 will descend along the thread at the lower part of the inner steam yarn tube 1. When the rotating nut 4 descends, the transmission rod 3 will drive the steam yarn sheet 2 to reset. The initial position of the rotating nut 4 is set at the bottom of the thread of the inner steam yarn tube 1.

[0039] In one embodiment of the present disclosure, a driven ring 5 is provided above the rotating nut 4, and one end of the transmission rod 3 is configured to be connected to the driven ring 5.

[0040] Specifically, as Figure 1 shown, a driven ring 5 is provided above the rotating nut 4, and one end of the transmission rod 3 is connected to the driven ring 5. The outer diameter of the driven ring 5 is smaller than the outer diameter of the rotating nut 4. Therefore, the rotating nut 4 can support the driven ring 5, enabling the driven ring 5 to be stably sleeved outside the thread of the inner steam yarn tube 1. When the rotating nut 4 is manually controlled to rotate counterclockwise, the rotating nut 4 will rise along the thread at the lower part of the inner steam yarn tube 1. When the rotating nut 4 rises, the transmission rod 3 will drive the steam yarn sheet 2 to expand outwards; when the rotating nut 4 is manually controlled to rotate clockwise, the rotating nut 4 will descend along the thread at the lower part of the inner steam yarn tube 1. When the rotating nut 4 descends, the transmission rod 3 will drive the steam yarn sheet 2 to reset. The initial position of the rotating nut 4 is set at the bottom of the thread of the inner steam yarn tube 1, so the initial position of the driven ring 5 is also set at the bottom of the thread of the inner steam yarn tube 1, and the driven ring 5 is always located above the rotating nut 4. When the rotating nut 4 moves upwards, the driven ring 5 moves upwards relying on the supporting force of the rotating nut 4. When the rotating nut 4 descends, the driven ring 5 moves downwards relying on its own gravity until it contacts the rotating nut 4.

[0041] In one embodiment of the present disclosure, the other end of the transmission rod 3 is configured to extend obliquely upwards to be hinged to the lower part of the steam yarn sheet 2.

[0042] Specifically, as Figure 1As shown, the transmission rod 3 is composed of a cross bar 6 and a vertical bar. One end of the vertical bar is connected to the driven ring 5, and the other end of the vertical bar is connected to the center of the cross bar 6. The cross bar 6 is connected to the inner wall of the steaming yarn sheet 2. The cross bar 6 is configured to extend obliquely upward to be hinged to the lower part of the steaming yarn sheet 2. The hinged connection enables the transmission rod 3 and the steaming yarn sheet 2 to rotate flexibly. When the rotating nut 4 is manually controlled to rotate counterclockwise, the rotating nut 4 will rise along the thread at the lower part of the steaming yarn inner tube 1. When the rotating nut 4 rises, the cross bar 6 of the transmission rod 3 will drive the steaming yarn sheet 2 to expand outward; when the rotating nut 4 is manually controlled to rotate clockwise, the rotating nut 4 will descend along the thread at the lower part of the steaming yarn inner tube 1. When the rotating nut 4 descends, the cross bar 6 of the transmission rod 3 will drive the steaming yarn sheet 2 to reset. The hinged design enables the steaming yarn sheet 2 not to be subjected to additional lateral forces during movement, thus avoiding wear or damage caused by rigid connection. Through the hinged connection, the transmission rod 3 can drive the steaming yarn sheet 2 to move at different angles to adapt to different position changes of the steaming yarn sheet 2. This design improves the adaptability and flexibility of the transmission rod 3. The design of the inclination angle of the transmission rod 3 needs to ensure better torque distribution during the expansion and reset processes to ensure that the transmission rod 3 can drive the steaming yarn sheet 2 smoothly throughout the movement process.

[0043] In one embodiment of the present disclosure, a cross bar 6 is provided at the other end of the transmission rod 3. Both ends of the cross bar 6 are configured to penetrate into through holes 8 provided in the inner wall of the steaming yarn sheet 2.

[0044] Specifically, as Figure 1 shown, connection portions 7 are pre - provided on the inner wall of the steaming yarn sheet 2, and two through holes 8 are provided on the connection portions 7. The above - mentioned two through holes 8 correspond to both ends of the cross bar 6. That is to say, both ends of the cross bar 6 can respectively pass through these two through holes 8, thereby realizing the hinged connection with the steaming yarn sheet 2. And the diameter of the through hole 8 is configured to be larger than the diameter of the cross bar 6. Therefore, it can be ensured that during the movement of the transmission rod 3, the cross bar 6 rotates in the through hole 8 as the position of the steaming yarn sheet 2 changes. The transmission rod 3 is provided as an integral structure, that is, the cross bar 6 is fixedly connected to the vertical bar. In this case, as long as the diameter of the through hole 8 is larger than the diameter of the cross bar 6, it can be realized that the transmission rod 3 rotates relative to the steaming yarn sheet 2 in the through hole 8 during the movement process. Among them, the connection method between the transmission rod 3 and the inner wall of the steaming yarn sheet 2 can meet the requirements of the steaming yarn sheet 2 to expand and reset under the action of the transmission rod 3. This design improves the adaptability and flexibility of the transmission rod 3.

[0045] In one embodiment of the present disclosure, connection portions 7 are provided on the inner wall of the steaming yarn sheet 2, the through holes 8 are provided on the connection portions 7, and both ends of the cross bar 6 are configured to be respectively hinged to the steaming yarn sheet 2 through the through holes 8.

[0046] Specifically, as Figure 1As shown in the figure, a connecting portion 7 is provided on the inner wall of the steaming sheet 2. The number of the connecting portions 7 is the same as the number of the transmission rods 3, and the number of the transmission rods 3 is the same as the number of the steaming sheets 2. That is to say, in order to ensure that each steaming sheet 2 can be opened by the same amplitude at the same time, a connecting portion 7 is provided at the same position of each steaming sheet 2, and each connecting portion 7 corresponds to a transmission rod 3. During the movement of the driven ring 5 along with the rotating nut 4, the multiple transmission rods 3 support the steaming sheets 2 to the same height with the same force at the same time. Such a design can ensure the synchronous movement of the multiple steaming sheets 2. The simultaneous expansion or reset of the multiple steaming sheets 2 can ensure that the yarn wound outside the steaming sheets 2 is uniformly heated during the heating and shaping processes, thereby improving the steaming effect.

[0047] In an embodiment of the present disclosure, a plurality of ventilation holes 9 are distributed on the steaming sheet 2.

[0048] Specifically, as Figure 1 shown, in order to further optimize the heating condition of the yarn during the steaming process, a plurality of ventilation holes 9 are uniformly provided on each steaming sheet 2 in the present disclosure. When the yarn is in the steaming device, the steam can flow through the ventilation holes 9, thereby avoiding the problem of uneven heating of the yarn wound on the steaming sheet 2 due to its position.

[0049] In an embodiment of the present disclosure, at least two steaming sheets 2 are configured to form a cylindrical structure sleeved outside the steaming inner tube 1 in the reset state.

[0050] Specifically, as Figure 1 shown, at least two steaming sheets 2 are configured to be sleeved outside the steaming inner tube 1 in a cylindrical shape in the reset state, which keeps a certain gap between the steaming sheets 2 and the steaming inner tube 1. During the steaming process, the steam can enter the gap between the steaming sheets 2 and the steaming inner tube 1 and pass through the ventilation holes 9 on the steaming sheets 2, thereby improving the steaming efficiency and avoiding the problem of uneven heating of the yarn wound on the steaming sheets 2 due to its position.

[0051] In an embodiment of the present disclosure, the steaming sheet 2 and the steaming inner tube 1 are integrally injection molded; the transmission rod 3 is configured to drive the steaming sheet 2 to deform during movement so that the steaming sheet 2 expands or resets.

[0052] Specifically, as Figure 1As shown, the steaming piece 2 and the steaming inner tube 1 are constructed by integral injection molding, which means that the steaming piece 2 and the steaming inner tube 1 are not assembled from multiple parts, but are manufactured into a complete component through a single injection molding process. This design reduces the connection points between components and improves the integrity and strength of the structure. The steaming piece 2 and the steaming inner tube 1 are usually injection molded with high-temperature and corrosion-resistant plastics or composite materials to adapt to the high-temperature environment during the steaming process. These materials also have good chemical resistance and mechanical properties, which can ensure the stability and reliability of the components during long-term use. When the transmission rod 3 pushes the steaming piece 2 to move outwards, relying on the good mechanical properties of the material, the steaming piece 2 expands outwards through the deformation of the part where the top of the transmission rod 3 is connected to the steaming inner tube 1.

[0053] In one embodiment of the present disclosure, the steaming inner tube 1 and the steaming piece 2 are constructed of polypropylene material.

[0054] Specifically, as Figure 1 shown, polypropylene (PP) is a material with good heat resistance, and its service temperature range is relatively wide, and it can maintain its physical properties at relatively high temperatures. During the steaming process, polypropylene can withstand the high-temperature steam environment to ensure the normal operation of the equipment. Polypropylene has good chemical corrosion resistance and can resist the erosion of various chemical substances, which is suitable for processing different types of yarns. Compared with metal materials, polypropylene has a smaller density, making the steaming piece 2 lighter during movement, reducing the load of the lifting mechanism, and improving the flexibility and stability of movement. Polypropylene also has good processing performance and can manufacture components with complex shapes through processes such as injection molding. This enables the steaming inner tube 1 and the steaming piece 2 to be designed into an integrated structure, simplifying the manufacturing and assembly process of the equipment.

[0055] For the steaming tube provided by the present disclosure, since at least two steaming pieces 2 are arranged around the outside of the steaming inner tube 1, and the steaming pieces 2 can be expanded or reset under the control of the lifting mechanism, the yarn is wound around the steaming pieces 2 in the expanded state, and then the steaming pieces 2 are reset. At this time, the yarn is in a relaxed state. Performing the steaming operation in this state can effectively avoid the problem of damaging the fiber strength of the yarn during the steaming process.
