DETAILED DESCRIPTION

[0016] The present application will be further described in detail below with reference to the accompanying drawings and examples. It can be understood that the specific examples described herein are only used to explain the related invention, and not to limit the invention. In addition, it should be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0017] It should be noted that the examples in the present application and the features in the examples can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and examples.

[0018] Yarn twist winding mechanism, such as Figure 1 And Figure 2 As shown in the drawings, the front end of the rack 1 is provided with a feeding wheel 2, a yarn tension adjusting device 3, a yarn guide 4 and a twist winding device 5 from top to bottom, the yarn tension adjusting device 3 includes an eccentric disc 31 and two adjusting wheels 32 fixed at different edges of the eccentric disc 31, and the eccentric disc 31 is rotated by a rotating motor fixed on the rear side of the rack 1, the rotating shaft of the eccentric disc 31 is located on the same vertical line with the feeding wheel 2 and the yarn guide 4,

[0019] The yarn guide hook 4 is in the shape of a number 9 and has an oblique opening for facilitating the insertion and removal of the yarn;

[0020] As shown in Figure 1 , Figure 2 and Figure 3 , the twisting and winding device 5 located below the yarn guide hook 4 on the frame 1 comprises a bobbin placing table 51 driven up and down by a pneumatic cylinder, a vertical bobbin placing column 511 fixed on the upper end surface of the bobbin placing table 51, the bobbin placing column 511 movably penetrating through a twisting table 52, an annular slide table 6 fixed on the upper end surface of the twisting table 52, the bobbin placing column 511 penetrating through the twisting table 52 at the same time movably penetrating through the pattern slide table 6, a sliding block 531 slidingly arranged on the upper end surface of the annular slide table 6, and a twisting ring 532 vertically arranged on the upper end surface of the sliding block 531, the sliding block 531 being an electric sliding block.

[0021] Before use, the bobbin is fixedly placed on the bobbin placing column 511, and then the yarn A is wound around the feeding wheel 2, the two adjusting wheels 32 on the yarn tension adjusting device 3, the yarn guide hook 4, the twisting ring 532 on the twisting device 53, and then fixed on the bobbin in parallel with the twisting ring 532. Figure 2 After fixing, the sliding block 531 is first started to make the twisting ring 532 slide on the annular slide table 6, so that the yarn A is twisted, and then the pneumatic cylinder fixedly connected with the bobbin placing table 51 is started.

[0022] At the same time when the yarn A is twisted, the twisted yarn A can be uniformly wound on the up and down moving bobbin through the twisting ring 532.

[0023] During the winding of the yarn A, since the yarn A is wound around the adjusting wheel 32, and a tension sensor is arranged on the adjusting wheel 32, when the tension sensor tests that the tension of the yarn A is too small, the eccentric disc 31 is counterclockwise rotated according to the above steps, at this time, the distance between the adjusting wheel 32 at the left end of the eccentric disc 31 and the feeding wheel 2 is increased, and the distance between the adjusting wheel 32 at the right end of the eccentric disc 31 and the yarn guide hook 4 is also increased, so that the winding distance between the feeding wheel 2 and the yarn guide hook 4 is increased, that is, the yarn A is stretched, so that the tension of the yarn A is increased, and the tension of the yarn A can be decreased according to the reverse process of the above steps, so that the adjustment is very convenient and fast.
