Description

Technical Field

[0001] The present invention relates to the technical field of spinning equipment, and in particular to a spinning device and a spinning method for improving yarn quality. Background Art

[0002] Spinning equipment processes fiber raw materials into yarn. Through a series of processes, including opening, carding, drafting, and twisting, loose fibers are combed into neatly arranged strands. Drafting further thins the strands, and finally, twisting imparts strength and elasticity to the yarn. Spinning equipment primarily includes ring spinning, air-jet spinning, air-jet spinning, and friction spinning. Ring spinning is a traditional spinning method, offering high quality. Air-jet spinning boasts high spinning speeds and is suitable for producing medium and low count yarns. Air-jet spinning utilizes airflow to twist the fibers, resulting in high production efficiency and unique yarn properties.

[0003] For example, the patent with application number CN202410487278.X discloses a vortex spinning device for improving the quality of low-count yarn, including several vortex spinning machines connected in sequence, the vortex spinning machine including a spinning body, a traction mechanism, a tensioning mechanism, a moisturizing mechanism, a processing mechanism and a winding mechanism. A yarn outlet is installed on the top of one side wall of the spinning body, the traction mechanism is installed on one side wall of the spinning body, and the traction mechanism is located below the yarn outlet, and the tensioning mechanism is fixedly installed in the middle of one side wall of the spinning body. The intermittent tightening and relaxation of the tensioning mechanism can improve the elasticity of the low-count yarn, increase the softness and comfort of the yarn, reduce the distortion and unevenness of the low-count yarn, and improve the quality and appearance of the textile. The moisturizing mechanism increases the humidity of the low-count yarn to avoid the low-count yarn from breaking due to insufficient humidity when tightened, and the impurities or excess fibers on the surface of the low-count yarn are removed by the surface treatment component. However, since the positions of the guide roller and the winding roller on the winding mechanism are relatively fixed and the two are horizontal, during the winding process, if the yarn is guided too fast, the guide connecting rod and the guide roller often cannot effectively support the yarn, causing the tension on the yarn to fluctuate during transportation, resulting in inconsistent tightness during winding, resulting in yarn overlap, dislocation and other phenomena, affecting the quality of the finished product.

[0050] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0051] According to Figure 1 、 2, as shown in Figures 3, 4, 5, 6, and 7, in this embodiment, a spinning device and a spinning method for improving yarn quality are proposed, including a cabinet 1, a drafting mechanism, a yarn guiding mechanism 8, and a winding assembly 9;

[0052] An upper support platform 10 and a lower support platform 11 are fixedly arranged inside the cabinet 1, and the upper support platform 10 is placed below the drafting mechanism;

[0053] The drafting mechanism is arranged on the top of the cabinet 1 and is used for stretching the carded fibers;

[0054] The yarn guiding mechanism 8 includes two rotating cylinders A81. The rotating cylinders A81 are rotatably arranged at the upper end of the upper support platform 10. A bracket 82 is fixedly arranged on the outer side of the rotating cylinder A81. A wire loop 83 is arranged at the top of the bracket 82. A kneading and waxing assembly 5 is arranged between the wire loop 83 and the drafting mechanism;

[0055] The winding assembly 9 includes two rotating cylinders B91 and a polygonal winding shaft 92 for hanging the yarn. The rotating cylinders B91 are rotatably arranged at the upper end of the lower support platform 11. The upper end of the rotating cylinder B91 passes through the rotating cylinder A81 and is rotatably connected to the rotating cylinder A81. The polygonal winding shaft 92 is sleeved on the outer side of the rotating cylinder B91 and is slidably connected to the rotating cylinder B91. A polygonal through groove slidably matched with the polygonal winding shaft 92 is formed in the center of the rotating cylinder B91;

[0056] When the yarn tension changes during the winding process, the wire loop 83 fine-tunes the yarn tension by rotating, so that the yarn tension remains relatively stable, which helps to improve the winding quality. When the rotating cylinder B91 rotates, the polygonal winding shaft 92 will also rotate. During the rotation of the rotating cylinder B91, it does not affect the sliding of the polygonal winding shaft 92 along the inner wall of the rotating cylinder B91.

[0057] It further includes:

[0058] A power assembly for controlling the reverse rotation of the rotating cylinders A81 and B91 and driving the two polygonal winding shafts 92 to make reciprocating lifting motions.

[0059] The carded sliver is introduced into cabinet 1 from above the cabinet 1 and stretched by a drafting mechanism to make the fibers reach the required fineness. After stretching, the yarn passes through the kneading and waxing assembly 5, and the kneading and waxing assembly 5 waxes the yarn to improve the smoothness of the yarn. After the yarn passes through the wire loop 83, it is wound around the polygonal winding shaft 92. The power assembly controls the rotation of the drum A81 and the drum B91. During the rotation of the drum A81, the bracket 82 is driven to rotate, and the yarn is wound around the rotating polygonal winding shaft 92 along a specific trajectory. During the process that the power assembly controls the rotation of the drum A81 and the drum B91, two polygonal winding shafts 92 are driven to do reciprocating lifting movements. The yarn is evenly distributed along the central axis direction of the polygonal winding shaft 92 during the winding process, so that the yarn is wound around the winding mechanism evenly and tightly, avoiding problems such as yarn slack, overlap or uneven winding, and improving the quality of the spun yarn.

[0060] Regarding the drafting mechanism:

[0061] The drafting mechanism includes rollers 2, a pressure regulator 3 and a driving member 4. The rollers 2 are rotatably arranged inside the cabinet 1;

[0062] The pressure regulator 3 includes a top roller 31 and a cylinder 33. Pressing plates 32 are provided at both ends of the top roller 31. One end of the pressing plate 32 away from the roller 2 is rotatably connected to the cabinet 1. The cylinder 33 is rotatably arranged at the upper end of the cabinet 1, and the output end of the cylinder 33 is rotatably connected to the pressing plate 32;

[0063] The driving member 4 includes a motor A43 and two pulley A41. The motor A43 is rotatably arranged outside the cabinet 1 and fixed inside the cabinet 1. The output end of the motor A43 and the roller 2 are respectively fixedly connected to the two pulley A41, and the two pulley A41 are connected by a transmission belt A42.

[0064] The carded sliver passes between the roller 2 and the top roller 31. The motor A43 controls the rotation of the pulley A41, and the pulley A41 drives the roller 2 to rotate through belt drive to realize the stretching of the sliver. The top roller 31 cooperates with the roller 2 to further draw out and thin the carded sliver, so that the fibers reach the required fineness and improve the straightness and parallelism of the fibers. By pushing the pressing plate 32 through the cylinder 33, the top roller 31 applies appropriate pressure to the sliver to ensure the smooth progress of the drafting process.

[0065] Regarding the power assembly:

[0066] The power assembly includes:

[0067] The first power member is arranged at the upper end of the upper support platform 10 and is used to control the rotation of the drum A81;

[0068] The second power member is arranged at the upper end of the lower support platform 11 and is used to control the rotation of the drum B91;

[0069] The vertical reciprocating mechanism 7 is arranged below the lower support platform 11 and is used to drive the two polygonal shafts 92 to perform reciprocating lifting movements when the rotating cylinder B91 rotates.

[0070] The first power component and the second power component work independently. The rotation of the support 82 and the rotation of the polygonal shaft 92 can be adjusted separately, and the winding tension and speed control of the yarn are more accurate. When the rotation speed of the support 82 is precisely matched with the rotation speed of the polygonal shaft 92, the yarn can be wound evenly and tightly on the winding mechanism.

[0071] The second power component works in coordination with the vertical reciprocating mechanism 7, enabling the winding mechanism to perform stable reciprocating lifting while rotating, ensuring that the yarn is evenly distributed along the winding axis direction during the winding process, and further improving the winding quality and the regularity of the package.

[0072] Specifically, the first power component includes a pulley B84 sleeved outside the rotating cylinder A81. The rotating cylinder A81 is fixedly connected to the pulley B84. The two pulleys B84 are connected by a transmission belt B85. A motor B86 is provided at the lower end of the upper support platform 10, and two pulleys C88 are provided at the upper end of the upper support platform 10. The output end of the motor B86 is fixedly connected to one of the pulleys C88. The two pulleys C88 are connected by a transmission belt C87. The other pulley C88 is sleeved outside the rotating cylinder A81, and the rotating cylinder A81 is fixedly connected to the pulley C88.

[0073] When the motor B86 is started, it controls the rotation of the pulley C88. The pulley C88 drives the rotation of the rotating cylinder A81 through belt transmission. The rotating cylinder A81 then drives another rotating cylinder A81 to rotate in coordination through belt transmission. The rotating cylinder A81 guides the yarn through the support 82 and the wire loop 83 during rotation.

[0074] Specifically, the second power component includes a pulley D93 sleeved outside the rotating cylinder B91. The pulley D93 is fixedly connected to the rotating cylinder B91. The two pulleys D93 are connected by a transmission belt D94. A motor E97 is provided at the lower end of the lower support platform 11, and two pulleys E95 are provided at the upper end of the lower support platform 11. The output end of the motor E97 is fixedly connected to one of the pulleys E95. The two pulleys E95 are connected by a transmission belt E96. The other pulley E95 is sleeved outside the rotating cylinder B91, and the rotating cylinder B91 is fixedly connected to the pulley E95.

[0075] When the motor E97 is started, it controls the rotation of the pulley D93. The pulley D93 drives the rotation of the rotating cylinder B91 through belt transmission. The rotating cylinder B91 then drives another rotating cylinder B91 to rotate in coordination through belt transmission. The rotating cylinder B91 winds the yarn on the reel on the polygonal shaft 92 through the polygonal shaft 92 during rotation.

[0076] Specifically, the vertical reciprocating mechanism 7 includes a movable plate 71 and a reciprocating lead screw B72. The movable plate 71 is slidably arranged inside the cabinet 1. The movable plate 71 is placed below the lower support platform 11. The reciprocating lead screw B72 is rotatably arranged at the lower end of the lower support platform 11. A nut seat B73 is sleeved outside the reciprocating lead screw B72. The nut seat B73 is threadedly connected to the reciprocating lead screw B72. The nut seat B73 is fixedly connected to the movable plate 71. The movable plate 71 is rotatably connected to two polygonal rotating shafts 92. The upper end of the reciprocating lead screw B72 is fixedly connected to a pulley E95.

[0077] When the second power component drives the rotating cylinder B91 to rotate, the rotating cylinder B91 will drive the reciprocating lead screw B72 to rotate through belt drive. The reciprocating lead screw B72 cooperates with the nut seat B73 during rotation. The nut seat B73 will perform a vertical reciprocating motion along the rod body of the reciprocating lead screw B72. The movable plate 71 is fixed to the nut seat B73. Therefore, the polygonal rotating shaft 92 will also be lifted and lowered synchronously under the push of the movable plate 71. The movable plate 71 is rotatably connected to the polygonal rotating shaft 92. When the movable plate 71 is lifted and lowered, it will not affect the rotation of the polygonal rotating shaft 92.

[0078] Regarding the kneading and waxing assembly 5:

[0079] The kneading and waxing assembly 5 includes an eccentric wheel A51 and an eccentric wheel B52. The eccentric wheel A51 is rotatably arranged inside the cabinet 1. A motor C55 for controlling the rotation of the eccentric wheel A51 is provided on the back of the cabinet 1. A cover plate 54 is provided on the front of the cabinet 1. The eccentric wheel B52 is rotatably arranged inside the cover plate 54. A motor B53 for controlling the rotation of the eccentric wheel B52 is provided outside the cover plate 54. A wax disk 56 is provided on the facing side of the eccentric wheel A51 and the eccentric wheel B52. Guide wheel mechanisms 6 are provided above and below the eccentric wheel A51. The guide wheel mechanisms 6 include a fixed guide wheel frame and a movable guide wheel frame.

[0080] During winding, the yarn discharged from the drafting mechanism passes between the eccentric wheel A51 and the eccentric wheel B52 under the guidance of the fixed guide wheel frame. The motor C55 controls the rotation of the eccentric wheel A51, and the motor B53 controls the rotation of the eccentric wheel B52. When the eccentric wheel A51 and the eccentric wheel B52 rotate, they will produce a kneading effect on the yarn, causing the sliver to rotate around its own axis, so that the fibers twist and hold each other. During the holding process, the wax disks 56 on the eccentric wheel A51 and the eccentric wheel B52 will evenly apply wax to the surface of the yarn bundle through friction with the fibers, improving the smoothness of the yarn. The yarn after kneading will be led to the yarn guiding mechanism 8 through the movable guide wheel frame and finally wound up.

[0081] Specifically, the fixed guide wheel frame includes a fixed rod 61. The fixed rod 61 is fixedly arranged inside the cabinet 1. A plurality of guide wheel groups A62 are fixedly arranged outside the fixed rod 61. The guide wheel groups A62 are placed above the eccentric wheel A51.

[0082] Specifically, the movable idler wheel frame includes a reciprocating lead screw A63 and a rotating shaft 66. The reciprocating lead screw A63 is rotatably arranged inside the cabinet 1. A nut seat A64 is sleeved outside the reciprocating lead screw A63. The nut seat A64 is threadedly connected to the reciprocating lead screw A63. Two idler wheel groups B65 are fixedly arranged outside the nut seat A64. The idler wheel groups B65 are placed below the eccentric wheel A51.

[0083] The rotating shaft 66 is rotatably arranged at the upper end of the upper support platform 10. The lower end of the rotating shaft 66 is fixedly connected to a pulley C88. Two bevel gears 67 are arranged on the rotating shaft 66. The two bevel gears 67 mesh with each other. One of the bevel gears 67 is fixedly arranged at the upper end of the rotating shaft 66, and the other bevel gear 67 is fixedly arranged outside the reciprocating lead screw A63.

[0084] Similarly, the movable idler wheel frame also adopts a collaborative design. When the first power component drives the rotating cylinder A81 to rotate, the rotating cylinder A81 will drive the rotating shaft 66 to rotate through belt drive. During the rotation of the rotating shaft 66, it will drive the reciprocating lead screw A63 to rotate through bevel gear drive. During the rotation of the reciprocating lead screw A63, it cooperates with the nut seat A64 to make the idler wheel groups B65 do horizontal reciprocating motion along the rod body of the reciprocating lead screw A63. The yarn led out between the eccentric wheel A51 and the eccentric wheel B52 will swing between the eccentric wheel A51 and the eccentric wheel B52 under the guidance of the idler wheel groups B65, further improving the waxing uniformity.

[0085] Working principle:

[0086] The carded sliver passes between the roller 2 and the top roller 31. The motor A43 controls the rotation of the pulley A41. The pulley A41 drives the roller 2 to rotate through belt drive to realize the stretching of the sliver. The top roller 31 cooperates with the roller 2 to further draw out and thin the carded sliver, making the fibers reach the required fineness and improving the straightening and parallelism of the fibers. By pushing the pressing plate 32 through the cylinder 33, the top roller 31 will apply appropriate pressure to the sliver to ensure the smooth progress of the drafting process.

[0087] During winding, the yarn discharged from the drafting mechanism passes between the eccentric wheel A51 and the eccentric wheel B52 under the guidance of the fixed idler wheel frame. The motor C55 controls the rotation of the eccentric wheel A51, and the motor B53 controls the rotation of the eccentric wheel B52. During the rotation of the eccentric wheel A51 and the eccentric wheel B52, they will produce a kneading effect on the yarn, making the sliver rotate around its own axis, so that the fibers twist and hold each other. During the holding process, the wax disks 56 on the eccentric wheel A51 and the eccentric wheel B52 will evenly apply wax to the surface of the yarn bundle through friction with the fibers to improve the smoothness of the yarn. The yarn after kneading will be led to the yarn guiding mechanism 8 through the movable idler wheel frame and finally be wound up.

[0088] The first power component and the second power component work independently. The rotation of the bracket 82 and the rotation of the polygon around the axis 92 can be adjusted separately, and the winding tension and speed control of the yarn are more accurate. When the rotation speed of the bracket 82 is precisely matched with the rotation speed of the polygon around the axis 92, the yarn can be wound evenly and tightly on the winding mechanism. The second power component works in cooperation with the vertical reciprocating mechanism 7, enabling the winding mechanism to perform smooth reciprocating lifting while rotating, ensuring that the yarn is evenly distributed along the winding axis direction during the winding process, and further improving the winding quality and the regularity of the package.
