Description

Technical Field

[0001] The present application relates to the field of textile methods, and in particular to a siro spinning process. Background Art

[0002] Siro spinning is a spinning process that produces yarn by stretching and lengthening two coarse yarns and then twisting them into a thin yarn. The yarn produced by Siro spinning has less hairiness, is loose inside and stiff outside, has a good hand feel, and is suitable for making light and thin fabrics.

[0003] In the Siro spinning process, the single yarn needs to be held by the rubber roller. In the actual production process, since the rubber roller has no travel, the contact point between the single yarn and the rubber roller is always located in the middle of the rubber roller. In addition, the Siro spinning speed is relatively fast, which causes the middle of the rubber roller to easily sag, causing the pressure of the rubber roller on the single yarn to be out of control. The rubber roller needs to be replaced more frequently, increasing production costs. Summary of the invention

[0039] Reference Figure 5 and Figure 6When the first mounting seat 3 rises, the ratchet 623 limits the rotation of the gear 621, and the driving screw 61 rotates with the cooperation of the rack 622 and the gear 621 to drive the second mounting seat 4 to slide. When the first mounting seat 3 descends, the rotation limit of the gear 621 by the ratchet 623 fails, the gear 621 rotates but the driving screw 61 does not rotate, and the second mounting seat 4 does not reset.

The pressure stop switch 926 is electrically connected to the adjusting motor. The pressure stop switch 926 is used to stop the adjusting motor.

[0042] Reference Figure 2 and Figure 5 When the second mounting seat 4 slides to the extreme position of unilateral sliding, the second mounting seat 4 presses against the pressure start switch 925 on that side, the adjusting motor starts to drive the transmission rod 923 to rotate, the transmission rod 923 drives the worm wheel 922 to rotate through the worm 924, the worm wheel 922 drives the adjusting screw 921 to rotate, the adjusting screw 921 drives the mounting plate 91 to slide and switch the meshing gear 621 rack 622 group, when the switching is completed, the mounting plate 91 presses against the pressure stop switch 926 on one side, and the adjusting motor stops.

[0043] Reference Figure 5The teeth at the lower end of the rack 622 are cut off, so that the gear 621 does not rotate in the initial stage of the first mounting seat 3 rising, avoiding the friction of the working rubber roller 21 on the yarn when the second mounting seat 4 moves synchronously with the first mounting seat 3. At the same time, it is also convenient to switch the meshing gear 621 and rack 622, so that there will be no collision of teeth during switching.

[0044] Reference Figure 1 The positioning mechanism 7 includes four positioning rollers 71 and four positioning rubber rollers 72.

Four positioning rubber rollers 72 are rotatably mounted on the four positioning frames 73 respectively, and the positioning rubber rollers 72 are parallel to the positioning rollers 71 and correspond to each other one by one.

[0046] Before the working rubber roller 21 releases the yarn to adjust its position, first move the four positioning rubber rollers 72 so that the four positioning rubber rollers 72 are respectively in close contact with the four positioning rollers 71 to temporarily position the yarn, and then adjust the working rubber roller 21 so that the yarn will not change position during the adjustment process of the working rubber roller 21.

[0047] Reference Figure 2 and Figure 3 The frame 1 is provided with a third driving mechanism 8, which includes four second springs 81, which are respectively located at four positioning frames 73. The second spring 81 is a tension spring, and both ends of the second spring 81 are respectively fixedly connected to the frame 1 and the positioning frame 73. The second spring 81 is extended and retracted along the sliding direction of the positioning frame 73. In the initial state, the positioning rubber roller 72 is separated from the positioning roller 71 under the action of the second spring 81.

[0048] Reference Figure 2 and Figure 4 The third driving mechanism 8 also includes four second sliders 82, which are slidably mounted on the frame 1. A third inclined surface 821 is integrally provided on one side of the second slider 82, and a fourth inclined surface 731 is integrally provided on one side of the positioning frame 73. The third inclined surface 821 and the fourth inclined surface 731 are parallel to each other.

[0049] Reference Figure 2 and Figure 4The third driving mechanism 8 also includes a third driving member 83, which includes a first connecting rod 831 and four second connecting rods 832.

The two ends of the second connecting rod 832 are respectively fixedly connected to the first connecting rod 831 and the second slider 82.

[0050] In the initial state, the pressure plate 521 fits tightly against the side wall of the first mounting seat 3 facing away from the working roller 22, and the third inclined surface 821 and the fourth inclined surface 731 fit tightly against each other. When the pressure plate 521 slides down driven by the driving cylinder 531 to the state where the first inclined surface 5211 and the second inclined surface 31 fit together, the second slider 82 pushes the positioning frame 73 to slide to the positioning rubber roller 72 and fit against the positioning roller 71 through the cooperation between the third inclined surface 821 and the fourth inclined surface 731. At this time, the bottom wall of the second slider 82 fits tightly against the top wall of the positioning frame 73.

[0051] The implementation principle of a siro spinning manufacturing process in an embodiment of the present application is as follows: through the control center of the spinning frame, the driving cylinder 531 is started at a fixed time every day, and the driving cylinder 531 drives the first slider 522 and the second slider 82 to slide, and the second slider 82 slides through the cooperation of the third inclined surface 821 and the fourth inclined surface 731 to push the positioning frame 73 to slide, so that the positioning rubber roller 72 is pressed against the positioning roller 71 to temporarily hold the yarn, and the first slider 522 slides to the first inclined surface 5211 and the second inclined surface 31 to fit tightly, so that the first mounting seat 3 and the working rubber roller 21 thereon slide in the direction away from the working roller 22 under the action of the first spring 51, and the working rubber roller 21 is separated from the working roller 22. During the rising process of the first mounting seat 3, the rack 622 drives the gear 621 to rotate, the gear 621 drives the driving screw 61 to rotate, and the driving screw 61 drives the second mounting seat 4 to slide to adjust the position.

[0052] When the second mounting seat 4 slides to the extreme position of unilateral sliding, the second mounting seat 4 presses against the pressure starting switch 925 on that side, the adjusting motor starts and drives the transmission rod 923 to rotate, the transmission rod 923 drives the worm wheel 922 to rotate through the worm 924, the worm wheel 922 drives the adjusting screw 921 to rotate, the adjusting screw 921 drives the mounting plate 91 to slide and switch the meshing gear 621 rack 622 group, when the switching is completed, the mounting plate 91 presses against the pressure stop switch 926 on one side, and the adjusting motor stops.

[0053] After the switch, when the first mounting seat 3 rises, the rack 622 drives the gear 621 to rotate, and the gear 621 and the driving screw 61 reverse to reset the second mounting seat 4 and the working rubber roller 21.
