[ detailed description ] embodiments
Please refer to fig. 1 to 5 of the specification, which show an automatic knot shearing device for high-strength yarn according to the present invention, comprising a frame 1, a tensioner 2, a mounting plate 3, a knot device 4, a scissors 5, a fixed lead screw 6, a movable lead screw 7, a rotary base 8, an adjusting knob 9, and a torsion spring 10.
Wherein, tensioner 2 and mounting panel 3 are installed respectively in frame 1, and tensioner 2 is located the top of mounting panel 3, and it is used for adjusting the tension of yarn 11.
The yarn knot device 4 is mounted on the mounting plate 3, and the yarn knot device 4 is the yarn knot device 4 mentioned in the background art, so the details are not described herein.
Further, said knotting device 4 comprises a fixed plate 41 and a movable plate 42; a yarn passing channel 43 is formed between the fixed plate 41 and the movable plate 42, and the size of the yarn passing channel 43 can be adjusted by the movable plate 42 so as to meet the production of yarns with different diameters.
The scissors 5 are mounted on the knotting device 4 above the thread passage 43, which can cut the thread 11.
The fixed lead screw 6 is fixed on the mounting plate 3; the movable lead screw 7 is positioned below the fixed lead screw 6 and is arranged in parallel with the fixed lead screw 6. An arc-shaped limiting groove 31 is formed in the mounting plate 3, and the movable lead screw 7 penetrates through the arc-shaped limiting groove 31 and can move in the arc-shaped limiting groove 31, so that the position of the movable lead screw 7 is changed. After passing through the yarn passing channel 43, the yarn 11 is sequentially abutted against the movable yarn passing rod 7 and the fixed yarn passing rod 6, and the normally passing yarn 11 is not contacted with the scissors 5 (as shown in figures 2 and 3), so that the normally passing yarn 11 is not cut by the scissors 5.
The movable lead screw 7 is vertically installed at one end of the rotary seat 8, the other end of the rotary seat is pivoted on the installation plate 3 through a pin shaft 81 and can rotate around the pin shaft 81, and therefore the rotary seat 8 drives the movable lead screw 7 to rotate around the pin shaft 81.
The adjusting knob 9 is arranged at one end of the pin shaft 81; the torsion spring 10 is sleeved on the pin shaft 81 and is abutted between the adjusting knob 9 and the rotating seat 8. The adjusting knob 9 can extend and retract along the radial direction of the pin shaft 81, so that the pressure of the torsion spring 10 abutting against the rotating seat 8 is adjusted, the twisting force of the movable thread passing rod 7 is adjusted, and the requirements on the tension of different yarns are met. For example, when the yarn strength is low, the adjusting knob 9 makes the pressure generated by the torsion spring 10 small, and the torsion force of the movable lead screw 7 is small; when the yarn strength is high, the adjusting knob 9 makes the pressure generated by the torsion spring 10 large, and the twisting force of the movable lead screw 7 is large.
Further, the bottom of the mounting plate 3 is provided with a wire passing ring 32, and the wire passing ring 32 is positioned below the wire passing channel 43; the yarn 11 passing through normally passes through the yarn passing ring 32, the movable yarn passing rod 7 and the fixed yarn passing rod 6 in sequence and is bent (as shown in figure 3), so that the movable yarn passing rod 7 can be pushed when the yarn 11 becomes tight due to the increased tension.
The invention relates to a method for automatically shearing a yarn knot of high-strength yarn, which comprises the following steps: as shown in the attached drawings 2 and 3 in the specification, the state that the yarn 11 normally passes through the yarn knotting device 4 is that the yarn 11 is unwound from a yarn bobbin, passes through the yarn passing ring 32, the yarn passing channel 43, the movable yarn passing rod 7 and the fixed yarn passing rod 6 in sequence, and then enters the tensioner 2 for tension adjustment. At this time, since the yarn 11 can pass through smoothly and the tension of the yarn 11 is small, the movable yarn passing rod 7 is positioned at the bottom of the arc-shaped limiting groove 31 and stops the yarn 11 to prevent the yarn 11 from contacting the scissors 5 to cut the yarn 11 accidentally.
As shown in fig. 4 and fig. 5 in the specification, when a yarn knot exists on the yarn 11 and cannot pass through the yarn passing channel 43, and the strength of the yarn 11 is strong, the yarn 11 cannot be broken by the yarn knot device 4, which causes the tension of the yarn 11 to be increased and straightened (as shown in fig. 5), the yarn 11 pushes the movable yarn passing rod 7 to rotate along the arc-shaped limiting groove 31 to the top of the arc-shaped limiting groove 31, at this time, the yarn 11 contacts with the scissors 5, and the yarn 11 is cut by the scissors 5. Thereby avoiding damaging the motor, the motor belt and other parts of the equipment, stabilizing the performance of the equipment and being not easy to damage.
The automatic knot shearing method for the high-strength yarns can also adjust the abutting force of the torsion spring 10 by rotating the adjusting knob 9, so that the torsion of the movable lead screw 7 and the rotary seat 8 is adjusted, and the automatic knot shearing method is suitable for the production of yarns with different strengths.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
