DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A flexible yarn feeding mechanism based on a rapier loom comprises a base 1, two conveying assemblies are arranged on the base 1, and an adjustment assembly is also arranged on the base 1. The conveying assembly comprises two symmetrically arranged support columns 2, two support shafts 3 are fixedly connected between the two support columns 2, the two support shafts 3 are symmetrically arranged, and conveying rollers 4 are rotatably connected to the two support shafts 3. The adjustment assembly comprises two support platforms 5 fixedly connected to the base 1, and lifting ports 6 are arranged on one side wall of the two support platforms 5 away from the base 1, and lifting seats 7 are slidably connected in the two lifting ports 6. Limiting grooves 18 are arranged on the inner walls of the two lifting ports 6, and limiting blocks 19 are slidably connected in the two limiting grooves 18. The two limiting blocks 19 are slidably connected. 9 are respectively fixedly connected to the two lifting seats 7, so that the lifting seats 7 can be effectively prevented from being completely separated from the lifting port 6 when the elastic force of the lifting spring 8 is automatically adjusted, which greatly guarantees the integrity of the device and the stability of the work. The two lifting ports 6 are both square, and the two lifting seats 7 are also square. The shapes of the two lifting seats 7 are respectively matched with the two lifting ports 6, so that the lifting seats 7 cannot rotate, and then the rotation of the threaded column 11 can be completed smoothly. The two lifting seats 7 and the inner walls of the two lifting ports 6 are respectively connected by two lifting springs 8. With the help of the setting of the lifting spring 8, the yarn can be effectively lifted and lowered, so that the yarn can be transported more stably and safely;

[0022] One of the conveying components is fixedly connected to the base 1, and the other conveying component is arranged on the adjustment component. A connecting structure is arranged between the adjustment component and the conveying component. The connecting structure includes a threaded groove 9 arranged on the upper end surface of one of the lifting seats 7, and a lifting groove 10 is arranged on the upper end surface of the other lifting seat 7. A threaded column 11 is threadedly connected in the threaded groove 9, and a lifting column 12 is slidably connected in the lifting groove 10. The lifting column 12 is fixedly connected to one of the supporting columns 2, and a rotating port 13 is arranged on the other supporting column 2. A rotating column 14 is rotatably connected in the rotating port 13, and one end of the rotating column 14 is fixedly connected to the threaded column 11. In this way, the height of this conveying component can be conveniently adjusted, and the fixed position of another conveying component can be coordinated to effectively control the initial tension state of the yarn, and then work can be carried out in coordination with the changing range of the yarn in different operations, which greatly meets the different usage needs of the staff. A turntable 15 is fixedly connected to the upper end surface of the rotating column 14, and the turntable 15 facilitates the staff to rotate the rotating column 14. An annular groove 16 is provided on the inner wall of the rotating mouth 13, and an annular block 17 is rotatably connected in the annular groove 16. The annular block 17 is fixedly connected to the rotating column 14, so that the rotation of the rotating column 14 is more stable, and there will be no problems such as falling and sliding.

[0023] During the use of the utility model, after the device is placed in the designated position, the staff can twist the rotating column 14 with the help of the turntable 15, and then drive the threaded column 11 to rotate in the thread groove 9 and lift it, and then drive the support column 2 to rise and fall to a suitable height through the rotating column 14 and the annular groove 16 and the annular block 17, so that the corresponding conveying component can be lifted and lifted to a suitable height, and then the relative height of this conveying component and another conveying component can be changed. In this way, when the yarn is conveying, the initial position of the conveying component can be set according to the needs, and then the corresponding needs, that is, the tension and relaxation range of the yarn can be met, and flexible adjustment work can be performed to meet the different processing needs of the staff. During the working process, the elastic force of the Capricorn lifting spring 8 pushes the lifting seat 7, and then pushes the corresponding conveying component, so that the yarn can be auxiliary tightened, and then the yarn can always remain in a stable state for conveying work. Such flexible yarn feeding work greatly guarantees the safety and stability of production work.
