Specifically, the yarn feeding mechanism is used for outputting yarns, the textile mechanism 4 weaves the yarns into the tubular fabric, and the winding mechanism winds the tubular fabric.

In the present embodiment, the thread feeding mechanism includes a thread feeding table 21 fixed to the tip end of the textile frame 12 and an adjusting device 3 provided on the thread feeding table 21. Send line platform 21 to be equipped with interior fixing base 22, well fixing base 23 and outer fixing base 24, interior fixing base 22, well fixing base 23 and outer fixing base 24 are the ring structure, and the same centre of a circle of three sharing, and outer fixing base 24 is located the outside, and well fixing base 23 is located outer fixing base 24, and interior fixing base 22 is located well fixing base 23. The outer fixing seat 24 is provided with a plurality of bobbin rods 25, the bobbin rods 25 are arranged on the upper surface of the outer fixing seat 24 at equal intervals, and the bobbin rods 25 are used for placing bobbins wound with yarns. The inner fixed seat 22 is fixed with tension wheels 26 which are arranged with equal distance and number corresponding to the number of the yarn cylinder rods 25, the middle fixed seat 23 is provided with adjusting devices 3 with number corresponding to the number of the yarn cylinder rods 25, and each adjusting device 3 is positioned between the corresponding yarn cylinder rod 25 and the tension wheel 26. The adjusting device 3 includes an extending plate 31 vertically fixed on the upper surface of the middle fixing seat 23, a groove is formed in the extending plate 31, a rotating shaft 32 with two ends fixed with the inner side surface of the groove is arranged in the groove, an adjusting wheel 33 is sleeved on the rotating shaft 32, and the adjusting wheel 33 can rotate on the rotating shaft 32 under the action of external force, as shown in fig. 4. The regulating wheel 33 is provided with an integrally formed thread groove 34, and the thread groove 34 is used for passing through yarns. The rotating shaft 32 is further sleeved with a spring 35, the spring 35 is located between the adjusting wheel 33 and the extension plate 31, one end of the spring 35 abuts against the adjusting wheel 33, and the other end of the spring 35 abuts against the extension plate 31. Specifically, the yarn on the yarn drum sequentially passes through the adjusting wheel 33, the tension wheel 26 and the circular hole in the middle of the inner fixing seat 22 to enter the spinning mechanism 4, and the yarn passes through the wire slot 34 in the process. The yarn is in a tight state under a normal state, the yarn between the yarn cylinder and the tension wheel 26 is in a tight state at the moment, namely the distance between the adjusting wheel 33 and the extension plate 31 reaches the nearest distance, and the stress contraction of the spring 35 reaches a critical point; when the yarn on one yarn drum is in an untightened state, the stress of the adjusting wheel 33 is reduced, and the spring 35 begins to rebound until the stress is balanced; when all the bobbins are in a state of not tight yarn, the stress of the bobbins is reduced to cause the yarn outlet speed to be reduced, all the regulating wheels 33 simultaneously approach the extension plate 31 until the distance between at least one regulating wheel 33 and the extension plate 31 reaches the nearest, and then the working state is circulated as described above.
