DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides an anti-entanglement vortex spinning device, which is mainly used to improve the quality of yarn.

[0025] like Figure 1 and Figure 2 As shown, it includes a vortex tube 1 with openings at both ends, wherein a first end cover 2 and a second end cover 3 are respectively installed at both ends of the vortex tube 1, a yarn feeding seat 21 extending to the inner cavity of the vortex tube 1 is fixedly provided on the first end cover 2, and a stationary spindle 31 extending to the inner cavity of the vortex tube 1 is fixedly provided on the second end cover 3, wherein a yarn feeding channel 211 for yarn to enter is provided on the yarn feeding seat 21, and a yarn outlet channel 312 for yarn to exit is provided on the stationary spindle 31, and a winding roller for winding the yarn is also provided on the outer side of the vortex tube 1, and the yarn is pulled outward by means of the winding roller.

[0026] It is worth noting that the winding roller at this time adopts a conventional roller, which only plays the role of pulling the yarn, which is well known to people in this field, and the structure of the winding roller is not described in detail here.

[0027] In this embodiment, if Figure 2 and Figure 5 As shown, the longitudinal section of the stationary spindle 31 is conical, and the tip of the stationary spindle 31 points to the yarn inlet seat 21.

[0028] In order to form a vortex in the vortex tube 1, in this embodiment, as Figure 3 , Figure 5 and Figure 6As shown, the outer wall of the vortex tube 1 is fixedly provided with an air inlet hole 11 connected to the inner cavity of the vortex tube 1, wherein the air inlet hole 11 is tangent to the inner wall of the vortex tube 1. In order to improve the vortex effect of the gas inside the vortex tube 1, in this embodiment, the air inlet holes 11 are provided in four groups and are evenly distributed along the circumference of the vortex tube 1.

[0029] The outer side of the vortex tube 1 is provided with an annularly distributed air distribution pipe 8, wherein the air distribution pipe 8 is connected to the air inlet 11, wherein the air distribution pipe 8 is also connected with an air supply pipe 100, wherein the air supply pipe 100 is connected to an external air source.

[0030] Through the above-mentioned arrangement, when it is necessary to form a vortex airflow inside the vortex tube 1, the external air source supplies high-pressure air to the inside of the distribution pipe 8 through the air supply pipe 100. At this time, the air inside the distribution pipe 8 enters the inner cavity of the vortex tube 1 through the air inlet hole 11. At this time, the air flow rotates along the inner wall of the inner cavity of the vortex tube 1, wherein the air inlet end and the air outlet end of the air inlet hole 11 are not on the same plane. At this time, the gas will vortex and flow downward along the inner wall of the vortex tube 1.

[0031] In order to discharge the gas inside the vortex tube 1 to the outside, in this embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, a plurality of air outlet holes 22 are provided on the first end cover 2, wherein the air outlet holes 22 are connected to the inner cavity of the vortex tube 1. It is worth noting that the air inlet hole 11 is close to one side of the second end cover 3, and the air flow inside the vortex tube 1 flows from one side of the second end cover 3 to one side of the first end cover 2, and finally discharges the vortex tube 1 from the air outlet holes 22.

[0032] In order to transport the sliver into the inner cavity of the vortex tube 1, in this embodiment, as Figure 3 and Figure 5 As shown, a cotton conveying channel 10 is opened on the side wall of the vortex tube 1. It is worth mentioning that the cotton conveying channel 10 is located below the air inlet 11. At this time, the cotton strips are fed into the inner cavity of the vortex tube 1 through the cotton conveying channel 10. With the flow of the air flow inside the vortex tube 1, the cotton strips are loosened in the inner cavity of the vortex tube 1 and move downward along the outer conical surface of the stationary spindle 31 in a spiral.

[0033] When the cotton strip moves to the yarn outlet channel 312 of the stationary spindle 31, the spirally moving cotton strip will be wound around the yarn. As the yarn gradually moves to the outside of the vortex tube 1 under the action of the winding roller, the cotton strip is driven to move along with the yarn.

[0034] It is worth mentioning here that the cotton strips entering the inner cavity of the vortex tube 1 are opened to form fiber bundles, and as the fiber bundles are spirally wound, they are gradually twisted and condensed, and then the fiber bundles can be wound onto the yarn core.

[0035] Traditionally, the inner cavity of the vortex tube 1 is cylindrical. At this time, the cotton slivers entering the inner cavity of the vortex tube 1 will move vertically along the inner wall of the vortex tube 1, resulting in poor capture effect of the yarn core on the cotton slivers. At this time, the cotton slivers are easily accumulated at the end of the inner cavity of the vortex tube 1, and then the fiber bundles are entangled into knots, affecting the quality of spinning.

[0036] In order to converge the cotton strips to the yarn core position, in this embodiment, as shown in FIG. Figure 2 , Figure 4 and Figure 5 As shown, a conical air guide hood 7 is provided in the inner cavity of the vortex tube 1, wherein the conical air guide hood 7 is located on the outside of the stationary spindle 31, and a gap for the movement of the cotton strips is left between the inner wall of the conical air guide hood 7 and the outer wall of the stationary spindle 31, and a feed port 72 is also provided at the tip of the conical air guide hood 7, wherein the feed port 72 is aligned with the yarn inlet channel 211 and the yarn outlet channel 312, and the yarn enters from the yarn inlet channel 211, and then penetrates into the yarn outlet channel 312 through the feed port 72.

[0037] Through the above-mentioned arrangement, the airflow inside the vortex tube 1 will flow toward the inner side of the conical air guide hood 7 while moving, and will flow downward along the inner wall vortex of the conical air guide hood 7, and then will flow out from the feed port 72. At this time, the cotton strips will enter the gap between the conical air guide hood 7 and the outer wall of the stationary spindle 31 under the action of the airflow, guide the cotton strips, and facilitate the capture of the cotton strips by the yarn core.

[0038] In order to smoothly transition the cotton strip to the inner wall of the conical air guide cover 7, in this embodiment, as shown in FIG. Figure 3 As shown, the inner wall of the vortex tube 1 is provided with an inclined guide ring 101, wherein the large diameter end of the conical guide cover 7 is inserted into the gap between the guide ring 101 and the inner wall of the vortex tube 1 to achieve the guidance of the cotton strips and airflow.

[0039] It is worth pointing out here that Figure 2 As shown, at this time, the inner wall of the vortex tube 1, the outer wall of the stationary spindle 31 and the inner wall of the conical guide cover 7 form a vortex chamber 102, wherein the air inlet 11 and the cotton conveying channel 10 are evenly connected to the vortex chamber 102.

[0040] In order to further strengthen the opening of the fiber bundles of the sliver in the vortex chamber 102 to form twists, in this embodiment, as Figure 2 As shown, a support frame 6 is also fixedly provided in the inner cavity of the vortex tube 1, wherein the outer wall of the conical air guide cover 7 is rotatably connected to the support frame 6, and also includes a driving mechanism for driving the conical air guide cover 7 to rotate. Specifically, the rotation direction of the conical air guide cover 7 is consistent with the vortex direction of the airflow.

[0041] Through the above arrangement, when the fiber bundle of the opened cotton strip moves to the inner wall of the conical air guide hood 7, as the driving mechanism drives the conical air guide hood 7 to rotate and the vortex of the fiber bundle moves, the fiber bundle contacts the inner wall of the conical air guide hood 7, and then the fiber bundle is twisted.

[0042] In order to realize the rotation of the conical air guide cover 7, in this embodiment, as shown in FIG. Figure 3 , Figure 5 and Figure 7 As shown, the driving mechanism includes an air blowing pipe 9 tangent to the inner cavity side wall of the vortex tube 1, wherein the air blowing pipe 9 is connected to the air supply pipe 100, and a plurality of circumferentially evenly distributed toggle plates 71 are fixedly provided on the outer wall of the conical air guide cover 7, wherein the air outlet end of the air blowing pipe 9 is aligned with the toggle plate 71.

[0043] Through the above arrangement, the air supply pipe 100 is used to supply air to the air blowing pipe 9 , and the gas in the air blowing pipe 9 is blown toward the shifting plate 71 , thereby driving the conical air guide cover 7 to rotate.

[0044] In order to further enhance the capture of the fiber bundle formed by the yarn core on the cotton strip, in this embodiment, Figure 4 As shown, an eccentric ring 721 eccentric to the axis of the yarn core is fixedly provided on the inner wall of the feed port 72, wherein the yarn core passes through the eccentric ring 721, and the conical air guide cover 7 drives the eccentric ring 721 to rotate while rotating. At this time, the inner wall of the eccentric ring 721 contacts the yarn core, thereby driving the yarn core to swing, thereby improving the yarn core's ability to capture the fiber bundle.

[0045] When the fiber bundle is wound on the yarn core, the fiber bundle is relatively fluffy. In order to increase the tightness of the fiber bundle on the yarn core, in this embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, a slot chamber 311 is provided at the axis position of the stationary spindle 31, wherein the slot chamber 311 is communicated with the yarn outlet channel 312, and a false twist pipe 4 is rotatably connected in the slot chamber 311, wherein one end of the false twist pipe 4 extends out of the second end cover 3 on the vortex tube 1, and a rotating wheel 5 is fixedly connected to the false twist pipe 4, wherein the rotating wheel 5 is connected to an external power source to drive the rotating wheel 5 to rotate;

[0046] It is worth mentioning here that the false twist pipe 4 is a hollow tube for the yarn core to pass through the inside of the false twist pipe 4, and the false twist pipe 4 includes a straight pipe section 41 and an arc section 42, wherein the straight pipe section 41 and the arc section 42 are integrally formed, and the axis of the arc section 42 is offset from the axis of the straight pipe section 41.

[0047] Through the above arrangement, an external power source is used to drive the false twist pipe 4 to rotate. At this time, the arc segment 42 will rotate eccentrically, thereby driving the internal yarn core to twist, strengthening the tightness of the cotton strip wrapped around the yarn core, reducing burrs on the yarn, and improving the quality of spinning.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
