Description

Technical Field

[0001] The utility model relates to the technical field of vortex spinning, in particular to a special spinning tube structure for vortex spinning yarns. Background Technique

[0002] Vortex spinning is a new spinning method that uses a stationary vortex spinning tube to replace the high-speed rotating spinning cup for spinning. During the vortex spinning process, the transfer, cohesion, twisting, and yarn formation of fibers are all completed by means of air flow. The structure of the vortex spinning device is simple, eliminating the high-speed rotating parts, and twisting the moving yarn strip by means of the high-speed rotating air flow.

[0003] At present, the vortex air flow used in vortex spinning yarns is formed by the tangential air intake along the spinning tube. However, the quality of the vortex air flow formed by this method is poor, reducing the transfer, cohesion, twisting, and yarn formation of fibers, thus reducing the quality of the finished yarn. Therefore, we propose a special spinning tube structure for vortex spinning yarns. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a special spinning tube structure for vortex spinning yarns, which has the advantages of being able to improve the quality of the vortex air flow formed inside the spinning tube during the vortex spinning process, thus facilitating the transfer, cohesion, twisting, and yarn formation of fibers, and then improving the quality of the finished yarn. It solves the problem that the vortex air flow used in current vortex spinning yarns is formed by the tangential air intake along the spinning tube, and the quality of the vortex air flow formed by this method is poor, reducing the transfer, cohesion, twisting, and yarn formation of fibers, thus reducing the quality of the finished yarn.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A special spinning tube structure for vortex spinning yarns, including a lower tube body and an upper tube body. The upper tube body is fixedly installed on the upper surface of the lower tube body. A central column is fixedly installed at the top of the inner wall of the upper tube body. A number of spiral blades are welded at equal intervals in a circular array between the outer surface of the central column and the inner wall of the upper tube body. An air inlet pipe is fixedly connected to one side of the upper surface of the upper tube body. A number of exhaust ports are equally spaced in a circular array on the outer surface of the lower tube body. A hollow spindle is fixedly installed at the bottom of the inner wall of the lower tube body. An adjusting nut is welded on the upper surface of the upper tube body. An adjusting screw rod is movably inserted into the adjusting nut. The end of the adjusting screw rod is fixedly connected to a yarn guiding needle. A fiber inlet is arranged at a position close to the adjusting nut on the upper surface of the upper tube body.

[0006] Preferably, the upper tube body and the lower tube body are fixedly connected by bolts and flange plates.

[0007] Preferably, a locking nut is welded on the outer surface of the adjusting nut, and a locking screw rod is movably inserted into the locking nut.

[0008] Preferably, a porous flow equalizing ring is fixedly installed at a position on the inner wall of the upper tube body above the spiral blade.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. By providing an upper tube body, a lower tube body, a hollow spindle, a yarn guide needle, a fiber inlet, a central column, and a spiral blade, the present utility model achieves the effect of improving the quality of the vortex air flow formed inside the spinning tube during the vortex spinning process, thereby facilitating the transfer, aggregation, twisting, and yarn formation of fibers, and then improving the quality of the finished yarn. The air flow enters between the central column and the upper tube body through the air inlet pipe, and the spiral blades distributed in an annular array form multiple spiral air flow channels between the central column and the upper tube body. Then, during the process of the air flow flowing along the multiple spiral air flow channels, a vortex air flow is formed and enters below the central column. Fibers enter the inside of the upper tube body from the fiber inlet, and are transferred, aggregated, twisted, and formed into yarn under the action of the vortex air flow. The finished yarn is led out from the hollow spindle.

[0011] 2. By providing an adjusting screw and an adjusting nut, the present utility model achieves the effect of facilitating the adjustment of the distance between the yarn guide needle and the hollow spindle according to production requirements. Turning the adjusting screw inside the adjusting nut can adjust the distance between the yarn guide needle and the hollow spindle to meet different production requirements.

[0012] 3. By providing a locking nut and a locking screw, the present utility model achieves the effect of preventing the yarn guide needle from loosening. Turning the locking screw inside the locking nut makes the end of the locking screw contact the outer surface of the adjusting screw, thereby locking and fixing the adjusting screw to achieve the purpose of fixing the yarn guide needle and preventing the yarn guide needle from loosening.

[0013] 4. By providing a porous flow equalizing ring, the present utility model can make the gas above the spiral blade enter each spiral gas flow channel evenly, thereby further improving the quality of the vortex air flow. Description of the Drawings

[0020] Embodiment 1

[0021] As Figures 1 - 4 shown, a special spinning tube structure for vortex spinning yarn proposed by the present utility model includes a lower tube body 2 and an upper tube body 3. The upper tube body 3 is fixedly installed on the upper surface of the lower tube body 2. The upper tube body 3 and the lower tube body 2 are fixedly connected by bolts and flange plates to facilitate the disassembly and internal maintenance of the two. The top of the inner wall of the upper tube body 3 is fixedly installed with a central column 12. A plurality of spiral blades 13 are welded at equal intervals in a circular array between the outer surface of the central column 12 and the inner wall of the upper tube body 3. The spiral blades 13 distributed in a circular array form a plurality of spiral air channels between the central column 12 and the upper tube body 3. One side of the upper surface of the upper tube body 3 is fixedly connected with an intake pipe 4. A plurality of exhaust ports 1 are equidistantly arranged in a circular array on the outer surface of the lower tube body 2. The bottom of the inner wall of the lower tube body 2 is fixedly installed with a hollow spindle 10. The hollow spindle 10 penetrates the lower tube body 2, and its two ends are respectively located inside and outside the lower tube body 2. An adjusting nut 9 is welded on the upper surface of the upper tube body 3. An adjusting screw 5 is movably inserted into the adjusting nut 9. The end of the adjusting screw 5 is fixedly connected with a yarn guide needle 11. The yarn guide needle 11 and the adjusting screw 5 penetrate the upper tube body 3 and the central column 12. A fiber inlet 6 is arranged at a position close to the adjusting nut 9 on the upper surface of the upper tube body 3. The fiber inlet 6 extends from the upper surface of the upper tube body 3 to the lower surface of the central column 12.

[0022] When the present utility model is in use, turning the adjusting screw 5 inside the adjusting nut 9 can adjust the distance between the yarn guide needle 11 and the hollow spindle 10 to meet different production requirements. The air flow enters between the central column 12 and the upper tube body 3 through the intake pipe 4. The spiral blades 13 distributed in a circular array form a plurality of spiral air channels between the central column 12 and the upper tube body 3. Then, during the process of the air flow flowing along the plurality of spiral air channels, a vortex air flow is formed and enters below the central column 12. The fibers enter the upper tube body 3 from the fiber inlet 6 and are transferred, condensed, twisted and formed into yarn under the action of the vortex air flow. The finished yarn is led out from the hollow spindle 10.
