The braiding machine body 1 comprises a table 101, a rail 102 and a feeding mechanism. The track 102 is arranged on the workbench 101, and the running mode of the track 102 can be realized by adopting the prior art; thus, the present embodiment does not show a description of the specific structure of the track 102. The feeding mechanism comprises a plurality of rotor assemblies 103 which are arranged at intervals, the rotor assemblies 103 are arranged on the guide rail, and the rotor assemblies 103 move along with the rotation of the track 102 in an S-shaped track. The rotor assembly 103 is used for mounting and fixing the bobbin 6, and a length of wire is wound around the bobbin 6. The rotor assemblies 103 rotate with the bobbins 6 to weave the yarns 7 into the webbing 8.

The guide mechanism 3 includes a mounting rod 31, a guide rod 32, and a stopper 33. One end of the mounting rod 31 is fixed on the mounting frame 2, one end of the mounting rod 31 far away from the mounting frame 2 is fixedly connected with the limiting piece 33, and a limiting hole 34 penetrated by the yarn 7 is formed in the limiting piece 33; so that a plurality of yarns 7 are woven into the webbing 8 at the position of the limiting holes 34. The guide rod 32 is arranged above the limiting piece 33, and the guide rod 32 is rotationally connected with the mounting rod 31; after the guide bar 32 and the mounting bar 31 are rotated relatively, the worker can fix the positions of the guide bar 32 and the mounting bar 31 relatively by providing a friction plate between the guide bar 32 and the mounting bar 31, or fixing by the bolts 27, or the like. The tension of the webbing 8 can be adjusted by a worker by adjusting the distance between the guide rod 32 and the limiting hole 34, so that the webbing 8 can be collected by the collection mechanism.

In this embodiment, the winding mechanism 5 includes a winding frame 51, two winding rollers 52 disposed in parallel, and a driving member 53. The wind-up rolls 52 are rotatably connected with the wind-up frame 51, and adjacent wind-up rolls 52 are connected through gears, and a gap for the webbing 8 to penetrate is formed between the two wind-up rolls 52. The driving member 53 is connected to one of the wind-up rolls 52 to drive the rotation of both wind-up rolls 52, thereby collecting the webbing 8 into the collecting frame outside the table 101.

Referring to fig. 3, the rotor assembly 103 includes a base 9 and a fixing frame 10, and the fixing frame 10 is mounted on the base 9 for mounting and fixing the bobbin 6. The base 9 of the rotor assembly 103 is clamped on the rail 102, so that the rail 102 can drive the rotor assembly 103 to move along an S-shaped track. The fixing frame 10 includes a lower cover plate 11, an upper cover plate 12, and a supporting member 13 disposed between the upper cover plate 12 and the lower cover plate 11. The lower cover plate 11 is fixedly connected with the supporting piece 13, the upper cover plate 12 is hinged with the supporting piece 13, and the winding reel 6 is arranged between the upper cover plate 12 and the lower cover plate 11. The support 13 comprises two parallel vertical rods 14, a mounting plate 15 sleeved on the periphery of the vertical rods 14, and the mounting plate 15 is arranged on the upper part of the vertical rods 14. So that the fixing frame 10 can mount and fix the bobbin 6.

As the spindle assembly moves along the track 102, the distance from the spindle assembly to the limiting aperture 34 changes, causing a slight slack in the tight yarn 7, affecting the tension of the yarn 7. When the size of the woven webbing 8 is required to be high, the webbing 8 woven by the partially relaxed yarn 7 has a certain influence on the uniformity of the diameter of the finished product. Accordingly, the present embodiment further improves the rotor assembly 103 to solve the above technical problems.

Referring to fig. 3, the spindle assembly further includes a sliding block 16 slidably connected to the vertical rod 14 of the support 13, and a first stopper ring 17 provided on a side wall of the sliding block 16. In addition, the spindle assembly includes a second stop collar 18 and a third stop collar 21. The second limiting ring 18 is arranged in the middle of the side wall of the mounting plate 15, and the third limiting ring 21 is arranged at the top of the mounting plate 15.

The yarn 7 on the bobbin 6 is woven into the webbing 8 after passing through the second limiting ring 18, the first limiting ring 17, the third limiting ring 21 and the limiting hole 34 on the limiting piece 33 in sequence. During the knitting of the yarn 7 into the webbing 8, the yarn 7 exerts an upward action on the slider 16, so that the slider 16 is suspended. And when the distance between the rotor assembly 103 and the limiting hole 34 changes, the yarn 7 loosens; the sliding block 16 applies a downward acting force to the yarn 7 under the action of gravity, so that the tension of the yarn 7 is improved. In the process of rotating the rotor assembly 103 carrying the winding reel 6, the sliding block 16 always has downward acting force on the yarn 7, so as to maintain the tension of the yarn 7 and improve the uniformity of the diameter of the braid 8.

Referring to fig. 3 and 4, the tension of the yarn 7 is further increased in order to automatically adjust the tension of the yarn 7 by the rotor assembly 103. This embodiment further limits the rotor assembly 103.

The rotor assembly 103 further comprises a sliding rod 22 and a spring 23, and correspondingly, the mounting plate 15 is provided with a sliding groove 24 which is inserted and slides by the sliding rod 22. One end of the sliding rod 22 slides and penetrates through the sliding groove 24, and the other end of the sliding rod 22 is fixedly connected with the sliding block 16. So that the slide bar 22 moves up and down together with the slide block 16. The spring 23 is disposed between the sliding rod 22 and the bottom of the sliding groove 24. So that when the yarn 7 pulls the slider 16 upwards, the slider 16 will press the spring 23 with the slider 22; when the yarn 7 is loosened, the spring 23 also applies a downward acting force to the sliding block 16, so that the yarn 7 is tensioned more timely, and the tension of the yarn 7 is improved timely.

Referring to fig. 3 and 4, the sidewall of the sliding groove 24 is further provided with ventilation holes 25, so that resistance of the sliding rod 22 when sliding in the sliding groove 24 is reduced.

Referring to fig. 3 to 5, an insertion rod 26 is further disposed at one end of the sliding rod 22 adjacent to the spring 23, and the diameter of the insertion rod 26 is smaller than the inner diameter of the spring 23, so that the insertion rod 26 is inserted into the spring 23. When the sliding rod 22 presses the spring 23, the plugging rod 26 plays a role in restraining the deformation direction of the spring 23; thereby enabling the spring 23 to be vertically compressed and deformed and reducing the lateral deformation of the spring 23; improving the stability of operation of the rotor assembly 103.

In addition, the present embodiment provides further improvements to the rotor assembly 103 in order to accommodate the tension requirements of the yarns 7 from the different webbing 8.

The bottom of the sliding groove 24 is provided with a threaded hole 28 for the bolt 27 to pass through. After the bolt 27 is screwed to the mounting plate 15, one end of the bolt 27 abuts against the spring 23. So that the operator can change the amount of downward force of the spring 23 on the slider 16 by inserting the bolt 27 into the length of the slider groove 24. When the yarn 7 pulls the slider 16 to shift the same distance, the longer the bolt 27 is screwed into the slider groove 24, the greater the compression of the spring 23, and the greater the force of the spring 23 on the slider 16.

referring to fig. 6, a flexible member 29 is provided inside the first stop collar 17 to reduce wear between the webbing 8 and the first stop collar 17. The flexible member 29 may be rubber, silicone, or the like.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
