[0035] like Figure 1-7As shown, a heald belt mechanism includes a frame 1, and heald belt components are evenly distributed on the outer periphery of the frame 1. Each heald belt component includes two heald belt adjusting seats 2, an upper heald belt 3, a lower heald belt 4, and a plurality of healds 5 connecting the upper heald belt 3 and the lower heald belt 4. The upper heald belt 3 and the lower heald belt 4 are respectively connected and installed on the frame 1 by a heald belt adjusting seat 2.

[0036] The two heald belt adjusting seats 2 are fixedly arranged on the frame 1 in an upper and lower structure. Each heald belt adjusting seat 2 includes a support part 21 for fixing, a mounting part 22 rotatably arranged with the support part 21, and two adjusting screws 24 passed through the mounting part 22. One end of the mounting part 22 is rotatably connected to the support part 21, and the other end of the mounting part 22 is rotatably provided with a roller 23. The two mounting seats 22 rotate in opposite directions according to the connection between their corresponding support parts 21. The upper heald belt 3 and the lower heald belt 4 are respectively covered on the outer circumference of the two rollers 23, so that the upper heald belt 3, the lower heald belt 4 and the heald wire 5 are pulled and tightened at both ends, so that the subsequent upper heald belt 3 and the lower heald belt 4 can move together more accurately through the two rollers 23.

[0037] The two mounting portions 22 are used to mount the ends of the upper heald belt 3 or the lower heald belt 4 toward the outside of the frame 1, and the upper heald belt 3, the lower heald belt 4 and the heald wire 5 are arranged on the outside of the frame 1 to prevent the frame 1 from affecting the subsequent actions of the upper heald belt 3, the lower heald belt 4 and the heald wire 5.

[0038] A hook 27 is provided at one end of the mounting portion 22, and a shaft body is provided on the support portion 21 for the hook 27 to rotatably hook, and an opening is opened on the hook 27 for the shaft body to enter and exit the hook 27. The hook 27 cooperates with the shaft body to realize the rotation of the support portion 21 and the mounting portion 22, and the assembly is simple and convenient. The other end of the mounting portion 22 faces the outside of the frame 1, and its end is rotatably connected to a roller 23 for mounting the upper heald belt 3 or the lower heald belt 4.

[0039] The support portion 21 is provided with a limiting surface for limiting the flipping angle of the mounting portion 22, which is used to limit the rotation angle of the mounting portion 22 to prevent the mounting portion from flipping downward to a snap-fit ​​state when the adjusting screw 24 does not rest on the circular loom. The rotation angle of the mounting portion can be limited by the limiting surface, which facilitates the assembly of the adjusting screw.

[0040] The adjusting screw 24 is threadedly connected to the supporting portion 21 . By rotating the adjusting screw 24 , the distance that the adjusting screw 24 passes through the mounting portion 22 can be adjusted, thereby adjusting the height of one side of the mounting portion 22 .

[0041] After passing through the support portion 21, the adjusting screw 24 always abuts against the end surface of the frame 1 for installing the heald belt adjusting seat 2, and is used to support and limit the distance between the two mounting portions 22. The distance between the adjusting screw 24 passing through the mounting portion 22 is adjusted by rotating to adjust the relative positions of the two rollers 23, and to limit the distance between the upper heald belt 3 and the lower heald belt 4, so that the upper heald belt 3 and the lower heald belt 4 and each heald wire 5 are straightened and tightened, which facilitates the subsequent regulation of the upper and lower heald belts 3 and 4 so as to adjust the position of the heald wire 5.

[0042] The two nuts can be loosened to rotate the adjusting screw 24 to regulate the rotation of the mounting portion 22, thereby adjusting the position of the heald between the two mounting portions.

[0043] Furthermore, a rotating shaft is passed through the roller 23, and a guide groove 25 for the rotating shaft to slide into is opened on the mounting portion 22. The guide groove 25 is inclined from the outside to the inside toward the middle of the frame 1. The upper heald belt 3, the lower heald belt 4 and the heald 5 pull the rollers 23 on both sides toward the heald 5. The guide groove 25 is inclined from the outside to the inside toward the middle of the frame 1 to prevent the roller from falling off the mounting portion 22 when subjected to a pulling force, and the inclined guide groove 25 can change the position of the roller relative to the inside and outside directions of the frame 1 when adjusting its position up and down, and synchronously drive the adjustment of the position of the upper heald belt 3, the lower heald belt 4 and the heald 5.

[0044] like Figure 1 As shown, a circular loom includes a heald belt mechanism and a control device. The heald belt mechanism includes the above-mentioned heald belt mechanism. A rocker rod 6 is provided between the control device and each heald belt assembly to achieve control. Each rocker rod 6 is provided on the upper end surface of the base 12. The middle part of the rocker rod 6 is supported and rotatably connected to the base 12 by a support member. The side of the rocker rod 6 facing the inside of the frame 1 is connected to the control device to control its up and down movement. The other end of the rocker rod 6 is a swinging end facing the outer periphery of the frame 1. The swinging end is connected to the lower heald belt 4 through a connecting member. The control device controls the up and down movement of the lower heald belt 4 by controlling the swing of the rocker rod 6 to adjust the position of the heald 5.

[0045] The frame 1 includes a circular loom top ring 11 and a circular loom chassis 12. The circular loom top ring 11 and the circular loom chassis 12 are generally circular structures. The two heddle belt adjustment seats 2 are respectively arranged on the top end surface of the circular loom top ring 11 and the bottom end surface of the circular loom chassis 12, so that the two heddle belt adjustment seats 2 are arranged one above and one below the frame 1.
