Description

Technical Field

[0001] The present invention relates to the field of fiber production equipment, and particularly provides an eddy current spinning draft device. Background Art

[0002] Eddy current spinning is a method of condensing and twisting fibers in a single fiber state by using the action of air eddy currents. Since the eddy currents replace the mechanical twisting and condensing actions and do not require rotating parts, the structure is simple and the spinning speed is relatively high, generally 6-7 times higher than ring spinning.

[0003] In a traditional drafting device, the fiber bundle after being drafted by a roller drafting device is output from the front roller nip, and then enters the spinning nozzle along a spiral fiber guiding channel under the action of the axial air flow at the inlet of the spinning nozzle. However, since eddy current spinning can only twist multiple fibers using the axial air flow after stretching, when the thickness of the fiber bundle is uneven or the diameter of the fiber bundle changes during the stretching process, the winding effect will be extremely unstable and the product quality cannot be guaranteed.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1.

[0017] 2. The installation plate, the gathering component, the heating component, the drafting component and the forming component are used to heat and draw the fibers in a multi-point, uniform and uniform speed manner, effectively improving the drafting performance and uniformity of the fibers, making the molecular arrangement of the fibers more uniform, improving the tensile performance and elongation rate of the fibers, and when stretching to the required thickness, it can also cut the stretched fibers, which is beneficial for subsequent winding and warehousing processes.

[0018] 3. When in the initial stage of stretching, since the fibers are relatively thick and it is necessary to accelerate the stretching efficiency, the meshing controller can be closed, so that the idling of the spiral column ends, and then when the chuck seat moves away from the vortex spinning device to stretch, the sliding seat will pause and not move, thereby reducing the stretching load, enabling the elongation rate of the output shaft of the drafting cylinder to be accelerated in the initial stage, and then accelerating the stretching rate. At the same time, since the inner sides of the two forming heads are concave with inclined guiding grooves, and the cutting surface of the cutting knife head and the bottom surface of the forming groove are located on the same horizontal plane, during the process of stretching the fibers and discharging the fibers after stretching, the cutting knife head will fit against the outer peripheral wall of the fibers, scraping off burrs, fiber knots and protrusions that may occur in the above process, improving the quality of the produced fibers.

An inclined guiding groove 544 is recessed inside the two forming heads 542, and a forming groove 545 is recessed through the outside of the guiding groove 544. One end of the shearing cutter head 543 is fixedly mounted in the middle of the inner side wall of the sliding extrusion block 541 and is located between the two forming heads 542, and the cutting surface of the shearing cutter head 543 and the bottom surface of the forming groove 545 are located on the same horizontal plane.

[0040] For example, in an embodiment: the fibers of the drawn sliver are sent to the gathering assembly 20 through the spinning nozzle. At this time, the gathering drive motor 22 will start, causing the first rotating shaft 231 to rotate, and transmitting the power to the two second rotating shafts 232 through the two first transmission belts 236, and then transmitting it to the two third rotating shafts 241 through the two second transmission belts 247, so that the two third rotating shafts 241 and the two second rotating shafts 232 rotate synchronously. At the same time, the adjusting cylinder 243 will start, causing the sliding wheel 244 to move along the control chute 214 towards the end away from the spinning nozzle, causing the two adjusting rods 245 to follow and rotate inwards around the sliding wheel 244, causing the two third rotating shafts 241 originally located at the ends of the two first arc-shaped chutes 219 to move towards the center of the gathering housing 21 along the two first arc-shaped chutes 219 and the two second arc-shaped chutes 215, and causing the two gathering wheels 242 to follow the movement, so that the two gathering wheels 242 clamp the fibers of the drawn sliver and move them towards the center of the gathering housing 21, causing the fibers of the drawn sliver to be quickly squeezed, compressed and conveyed between the two tightening wheels 233, and conveyed to the first tightening tube 235 and the subsequent working components through the tightening wheels 233. When the fibers of the drawn sliver are conveyed into the first tightening tube 235, due to the rotation of the first rotating shaft 231, the first bevel gear on the first rotating shaft 231 will follow the rotation, causing the second bevel gear to follow the rotation, causing the first tightening tube 235 to follow the rotation. Since the inside of the first tightening tube 235 is recessed with a spiral guiding and forming hole, the fibers of the drawn sliver entering it will be torsionally extruded, causing the fibers to be initially fiber-condensed and formed, ensuring the uniformity and stability of the fibers while increasing the density of the fiber bundle and reducing the voids, making the fibers more compact, so that the device can perform operations such as conveying, regularizing, squeezing and preliminary forming on the fibers of the drawn sliver entering.

[0041] For example, in one embodiment: When the fiber is fed into the heating assembly 30, the drive motor 33 will start, causing the driving gear 37 to rotate, and then causing the driven gear 36 to rotate accordingly, causing the heating roller 35 to rotate accordingly, and then heating and conveying the fiber in multiple directions evenly. Subsequently, the heated fiber is sent to the forming assembly 50, passes through the clamping holes 515 and the wire holes 422 in sequence, and the fiber is clamped therein by the second clip and the first clip in the clamping holes 515 and the wire holes 422. Subsequently, the stretching cylinder 41 is started, causing the chuck seat 42 to move away from one end of the vortex spinning device. Subsequently, the sorting cylinder 531 is started, causing the output shaft of the sorting cylinder 531 to extend, causing the first lever 532 to rotate around its middle, causing the lever rotating shaft 534 to move towards one end of the vortex spinning device, causing the second lever 533 to rotate accordingly, so that the first driven lever 535 and the second driven lever 536 rotate inward, and then causing the two sliding extrusion blocks 541 to slide inward along the second slide rail 522 until the forming grooves 545 in the two forming heads 542 clamp the outer wall of the heated fiber. Subsequently, the stretching process is performed on the heated fiber. Since one end of the spiral column 46 is installed in the first spiral hole 432 of the fixed seat 43, the other end of the spiral column 46 is rotatably installed at the bottom of the end wall of the chuck seat 42, and the inner side wall of the fixed seat 43 is fixedly installed at the middle of the outer side wall of the mounting plate 10. At the same time, the meshing controller 443 is started, so that when the spiral column 46 rotates, it will idle in the meshing controller 443, that is, when the chuck seat 42 moves away from one end of the vortex spinning device, the spiral column 46 will rotate, and then the sliding seat 44 will move away from one end of the vortex spinning device along the sliding column 45. At the same time, the stretching cylinder 513 is started, causing the stretching cylinder 513 to extend, causing the connecting column 521 to move away from one end of the vortex spinning device, causing the forming mounting plate 52 to move away from one end of the vortex spinning device synchronously along the first slide rail 511, causing the two forming heads 542 to move following the clamping of the heated fiber, and then stretching the fiber in multiple points, evenly, and at a constant speed, effectively improving the drafting performance and uniformity of the fiber, making the molecular arrangement of the fiber more uniform, and improving the stretching performance and elongation of the fiber. Until the required thickness is stretched, the second clip and the first clip will open, the sorting cylinder 531 will retract, and the stretching cylinder 41 will retract, causing the inner forming head 542 to abut against the outer side wall of the chuck transition plate 421, and the stretched fiber will be discharged from the wire hole 422. Subsequently, the output shaft of the sorting cylinder 531 will quickly extend, causing the two forming elements 54 to quickly move inward along the two second slide rails 522, and using the cutting tool head 543 therein to cut the stretched fiber, which is beneficial for subsequent winding and warehousing processing.

[0042] For example, in one embodiment: When, at the initial stage of stretching, since the fibers themselves are relatively thick and it is necessary to increase the stretching efficiency, the engagement controller 443 can be turned off, so that the idling of the spiral column 46 ends, and then when the chuck seat 42 moves away from one end of the vortex spinning device for stretching, the sliding seat 44 will pause and remain stationary, thereby reducing the stretching load, enabling the rate of elongation of the output shaft of the drafting cylinder 41 to be increased at the initial stage, and thus increasing the stretching rate. At the same time, since inclined guiding grooves 544 are recessed on the inner sides of the two forming heads 542, and the cutting surface of the cutting knife head 543 and the bottom surface of the forming groove 545 are located on the same horizontal plane, during the process of stretching the fibers and during the process of discharging the fibers after stretching is completed, the cutting knife head 543 will fit against the outer peripheral wall of the fibers, scraping off burrs, fiber knots, protrusions, and other situations that may occur to the fibers during the above processes, improving the quality of the produced fibers.
