[0011] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific embodiments, structures, features and their effects according to the present utility model as follows.
[0012] Embodiment 1:
[0013] Such as Figures 1-4As shown in the figure, the utility model discloses a yarn tension compensation device for a rapier loom, which includes a vertical plate 1. A first guide roller 2 is provided on the vertical plate 1, and a second guide roller 3 is provided on the vertical plate 1. The first guide roller 2 and the second guide roller 3 are in the same horizontal position. A chute 4 is vertically provided on the vertical plate 1. The chute 4 is located between the first guide roller 2 and the second guide roller 3. The bottom end of the chute 4 is lower than the first guide roller 2 and the second guide roller 3. A first slider 5 is slidably provided in the chute 4. The first slider 5 can be displaced vertically along the chute 4. A rotating shaft 11 is rotatably provided on the first slider 5 in a direction perpendicular to the surface of the vertical plate 1. The rotating shaft 11 penetrates through the first slider 5. A tensioning roller 6 is rotatably provided at one end of the rotating shaft 11 on the same side as the first guide roller 2. The tensioning roller 6 includes a rotating roller 61. Baffles 62 are provided at both ends of the rotating roller 61. The baffles 62 and the rotating roller 61 are connected by a rotating ring 63. An annular air cavity is formed between the baffles 62 on both sides of the rotating ring 63 and the two ends of the rotating roller 61. The rotating ring 63 is coaxially arranged with the rotating roller 61. A plurality of through holes 65 are radially provided on the side surface of the rotating ring 63. A main air pipe 14 is axially provided in the rotating shaft 11. A plurality of air outlet pipes 12 are radially provided on the rotating shaft 11 corresponding to the rotating ring 63, so that the air cavities outside and inside the rotating ring 63 can communicate. The air outlet pipes 12 are communicated with the main air pipe 14. One end of the main air pipe 14 away from the tensioning roller 6 is connected with a flexible pipe 13. One end of the flexible pipe 13 is fixed on one side of the vertical plate 1. The outer edge of the baffle 62 is bent towards the center to form a wind guiding groove 64. One end of the flexible pipe 13 is connected with a blower to convey air flow to the main air pipe 14. The air flow enters the air cavity inside the rotating ring 63 through the air outlet pipes 12, enters the air cavity outside the rotating ring 63 through the through holes 65 of the rotating ring 63, and the air flow entering the air cavity outside the rotating ring 63 moves outwards. The outward moving air flow is guided by the wind guiding groove 64 to the rotating roller 61, and an air flow is formed on the outer surface of the rotating roller 61. The air flow plays an auxiliary supporting role for the yarn wound around the rotating roller 61, reduces the friction between the yarn and the rotating roller 61, and reduces the wear of the yarn. A second slider 7 is slidably provided above the first slider 5. The first slider 5 and the second slider 7 are connected by a spring 8. A screw rod 9 is vertically provided on the vertical plate 1 above the chute 4. The screw rod 9 is threadedly connected with the vertical plate 1. The lower end of the screw rod 9 is rotatably connected with the second slider 7. During normal operation, the yarn is wound in the order of the first guide roller 2 - the tensioning roller 6 - the second guide roller 3. When the yarn is pulled, the yarn tension will drive the tensioning roller 6 and the first slider 5 to move upwards. The spring 8 plays a role in applying pressure to keep the first slider 5 stable. By adjusting the distance between the first slider 5 and the second slider 7 through the screw rod 9, the tightness of the spring 8 can be adjusted to adapt to the tension of yarns of different specifications.
[0014] An axial rotating wheel 10 is provided at the upper end of the screw rod 9 to assist in rotating the screw rod 9.
[0015] The screw rod 9 and the second slider 7 are rotatably connected and are integrated, that is, the gravity of the second slider 7 acts on the screw rod and does not act on the first slider.
