Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to a spinning device for producing false-twist yarn by air vortex spinning. Background Art

[0002] Air vortex spinning is a non-traditional spinning method. When using a jet air flow to twist the fiber sliver after drafting, some free fibers at the head ends on the fiber sliver are wrapped around the periphery of the fiber sliver for spinning. There are two types: single-nozzle type and double-nozzle type. The latter has good and stable spinning quality. The fiber sliver is thinned by the drafting device, and false twisting is to fix both ends of a rope and apply twist in the middle. One side becomes tighter and tighter when twisted, while although the other side also becomes tighter and tighter when twisted, the twist direction is opposite. Therefore, the total twist number on the rope does not change.

[0003] However, in the existing spinning device during the winding process, since false twisting needs to be carried out by fixing both ends and applying twist in the middle, it may cause the yarn to become tighter and tighter during the twisting process. If there is no device for adjusting the yarn tension, the yarn tightened by the false-twist cylinder will break. Therefore, a spinning device for producing false-twist yarn by air vortex spinning is proposed. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1-4, A jet vortex spinning false twist yarn spinning device, including an installation housing 1. A vertical electric push rod 2 is fixedly arranged at the top of the installation housing 1. The output end of the vertical electric push rod 2 is fixedly provided with a moving frame 3. A mounting box 4 is fixedly arranged in the middle of the moving frame 3. A pressure sensor 5 is fixedly arranged on the lower side wall of the mounting box 4. The detection end of the pressure sensor 5 is lapped with a movable plate 6. The movable plate 6 is of a rectangular structure and is made of metal. The metal-made movable plate 6 can withstand greater pressure, so that the movable plate 6 is not easily deformed during use, avoiding the situation that the movable plate 6 is deformed and cannot squeeze the pressure sensor 5. A fixing plate 7 is fixedly arranged at the top of the movable plate 6. A tension adjusting wheel 8 is rotatably arranged inside the fixing plate 7. A limiting box cover 9 is lapped on the top of the mounting box 4. Metal blocks 10 are fixedly arranged on both the front and rear sides of the limiting box cover 9. The surface of the metal block 10 is lapped with a metal buckle 11. The number of the metal blocks 10 and the metal buckles 11 is two each, and the two metal blocks 10 and the two metal buckles 11 are symmetrically distributed. The inclined surface of the limiting box cover 9 drives the metal block 10 to squeeze the inclined surface of the metal buckle 11, causing the metal buckle 11 to deform. When the bottom of the limiting box cover 9 contacts the top of the mounting box 4, the metal buckle 11 rebounds through deformation and inserts into the top of the metal block 10. Pulling the metal buckle 11 to deform makes the metal buckle 11 and the metal block 10 separate, and then the limiting box cover 9 can be removed, which is convenient for the movable plate 6 to contact the pressure sensor 5 and is convenient for maintaining the pressure sensor 5. The metal buckle 11 is fixedly installed on the surface of the mounting box 4. The limiting box cover 9 is of a rectangular structure. A rectangular connection groove for the fixing plate 7 to slide through is provided through the top of the limiting box cover 9. The limiting box cover 9 is made of metal. Through the setting of the connection groove, the movable plate 6 pushes the fixing plate 7 through the connection groove, making the movable plate 6 contact the bottom of the limiting box cover 9 and placing the limiting box cover 9 on the top of the mounting box 4, so that the metal buckle 11 is inserted on the surface of the metal block 10, thus making the top of the movable plate 6 contact the pressure sensor 5, which is convenient for installing the movable plate 6 inside the mounting box 4 and is convenient for connecting the limiting box cover 9 with the fixing plate 7 and the mounting box 4. An inlet yarn tube 12 is fixedly arranged on the left side of the installation housing 1. An outlet yarn tube 13 is rotatably arranged on the right side of the installation housing 1. A jetting component is arranged on the inlet yarn tube 12. A fixing component is arranged on the installation housing 1. A driving component is arranged inside the installation housing 1. By driving the output end of the vertical electric push rod 2 to extend or shorten, the mounting box 4 drives the pressure sensor 5 to move downward or upward. At the same time, the mounting box 4 drives the limiting box cover 9 to move downward or upward through the metal block 10 and the metal buckle 11, so that the movable plate 6 drives the tension adjusting wheel 8 to move downward or upward through the fixing plate 7. The false twist yarn is pushed upward by the tension adjusting wheel 8, or the false twist yarn is relaxed. At the same time, the tension of the false twist yarn will push the tension adjusting wheel 8 to apply pressure downward, making the fixing plate 7 push the movable plate 6 to push the pressure sensor 5 to apply pressure.The tension of the yarn is detected by the pressure sensor 5, thus avoiding the situation that the tension of the false-twisted yarn is too small or too large. It avoids the false-twisted yarn from being too loose due to too small tension, and also avoids the situation that the false-twisted yarn breaks due to too large tension.

[0021] Specifically, the jet component includes an annular air pipe 14. Inside the annular air pipe 14, a jet pipe 15 is fixedly arranged. The jet pipe 15 is fixedly installed inside the yarn inlet pipe 12. At the top of the jet pipe 15, an air inlet pipe 16 is fixedly arranged. The external air supply device transports gas to the annular air pipe 14 through the air inlet pipe 16 for shunting. The shunted gas enters the jet pipe 15 and is ejected, thus facilitating the adsorption of the yarn together.

[0022] Specifically, the fixing component includes a U-shaped mounting plate 17. The U-shaped mounting plate 17 is fixedly installed at the rear side of the mounting housing 1. At the rear side of the U-shaped mounting plate 17, a horizontal electric push rod 18 is fixedly arranged. At the output end of the horizontal electric push rod 18, a pushing plate 19 is fixedly arranged. At the front side of the pushing plate 19, a pushing rod 20 is fixedly arranged. A clamping magnet 21 is lapped on the surface of the pushing rod 20. At one side of the clamping magnet 21, a limiting rod 22 is fixedly arranged. A connecting plate 23 is slidably arranged on the surface of the limiting rod 22. The number of the connecting plates 23 is four. The four connecting plates 23 are respectively fixedly installed on the yarn inlet pipe 12 and the yarn outlet pipe 13. The horizontal electric push rod 18 drives the pushing rod 20 to move through the pushing plate 19, so that the pushing rod 20 is separated from the clamping magnet 21. The upper and lower clamping magnets 21 are adsorbed together to clamp and fix the yarn, thus facilitating the subsequent false twisting of the yarn.

[0023] Specifically, the driving component includes a driving motor 24. The driving motor 24 is fixedly installed on the right side wall of the mounting housing 1. At the output end of the mounting housing 1, a driving gear 25 is fixedly arranged. A driven gear 26 is meshed on the surface of the driving gear 25. The driven gear 26 is fixedly installed on the surface of the yarn outlet pipe 13. The driving motor 24 drives the driving gear 25 to drive the driven gear 26 to rotate, so that the driven gear 26 drives the yarn outlet pipe 13 to rotate inside the mounting housing 1, thus facilitating the yarn outlet pipe 13 to drive the clamping magnet 21 to move through the connecting plate 23 and the limiting rod 22, thus facilitating the false twisting of the yarn and making the false twisting of the yarn more automated.

[0024] The jet vortex spinning false-twisting yarn spinning device is connected to the 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: Insert the yarn into the installation housing 1 through the yarn inlet tube 12, and make the yarn pass through the top of the tension adjusting wheel 8 and pass out of the yarn outlet tube 13. Among them, gas is supplied to the intake pipe 16 by an external gas supply device. After the gas is split by the annular gas pipe 14, it enters the inside of the jet pipe 15 to blow the yarns together. Drive the output end of the horizontal electric push rod 18 to drive the push plate 19 to slide backward in the horizontal electric push rod 18, so that the push plate 19 drives the push rod 20 to separate from the clamping magnet 21. The upper and lower clamping magnets 21 are adsorbed together by magnetic force, and the clamping magnet 21 is guided by the limit rod 22 and the connecting plate 23, so that the upper and lower clamping magnets 21 fix the yarn. Then, drive the output end of the drive motor 24 to drive the driving gear 25 to rotate. The driving gear 25 drives the driven gear 26 meshed with it to rotate, and drives the yarn outlet tube 13 to rotate through the driven gear 26, so that the yarn outlet tube 13 drives the clamping magnet 21 to move through the connecting plate 23 and the limit rod 22, and false twist the yarn through the clamping magnet 21. During the false twisting process, drive the output end of the vertical electric push rod 2 to drive the moving frame 3 to move upward, so that the moving frame 3 drives the installation box 4 to move upward, so that the installation box 4 pushes the pressure sensor 5 and the limit box cover 9 to move upward, and drives the metal block 10 and the metal buckle 11 to move upward through the installation box 4 and the limit box cover 9, so that the pressure sensor 5 pushes the movable plate 6 to move upward, so that the movable plate 6 drives the tension adjusting wheel 8 to drive the false-twisted yarn to move through the fixing plate 7, so that the false-twisted yarn will push the tension adjusting wheel 8 to apply pressure downward after being tensioned, so that the tension adjusting wheel 8 squeezes the pressure sensor 5 through the fixing plate 7 and the movable plate 6. Detect the applied pressure through the pressure sensor 5. If the pressure is too small, control the tension adjusting wheel 8 to push the yarn to move upward. If the tension of the false-twisted yarn is too large, control the tension adjusting wheel 8 to move downward to relax the tensioned yarn.

[0026] In summary, for this air-jet vortex spinning false-twist yarn spinning device, by driving the output end of the vertical electric push rod 2 to extend or shorten, the installation box 4 drives the pressure sensor 5 to move downward or upward. At the same time, the installation box 4 drives the limit box cover 9 to move downward or upward through the metal block 10 and the metal buckle 11, so that the movable plate 6 drives the tension adjusting wheel 8 to move downward or upward through the fixing plate 7. Push the false-twisted yarn to move upward, or relax the false-twisted yarn. At the same time, the tension of the false-twisted yarn will push the tension adjusting wheel 8 to apply pressure downward, so that the fixing plate 7 pushes the movable plate 6 to push the pressure sensor 5 to apply pressure. Detect the tension of the yarn through the pressure sensor 5, thus avoiding the situation that the tension of the false-twisted yarn is too small or too large, avoiding the situation that the false-twisted yarn is too loose due to too small tension, and avoiding the situation that the false-twisted yarn breaks due to too large tension, which is used to solve the problems raised in the above background technology.
