[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0029] Please refer to Figures 1-4 The above technical solutions will be described in detail through the following embodiments.

[0030] The sliver guiding roller of the drawing frame comprises a mounting frame 1. In order to better support and convey the sliver and avoid accidental drafting and winding of the sliver during the guiding process, as shown in Figure 1 and Figure 2 , a water platform frame 3 is mounted on the side of the pressing and guiding part 2 where the sliver is fed, and vertical rollers 4 are detachably mounted on the water platform frame 3. Gaps are left between the adjacent vertical rollers 4, and the feeding path of the sliver can be limited through the gaps.

[0031] The pressing and guiding part 2 has the structure as shown in Figure 3 and Figure 4 . In the embodiment, the pressing and guiding part 2 comprises a U-shaped bracket 21 horizontally mounted on the mounting frame 1, and a supporting roller 29 coaxially mounted on the U-shaped bracket 21 through a driving motor 27. In order to keep the sliver compact during the drawing process, a pressing roller 28 is mounted above the supporting roller 29. The pressing roller 28 in the embodiment can adjust the distance between the pressing roller 28 and the supporting roller 29 to be suitable for slivers of different specifications.

[0032] Specifically, a gas cylinder 23 is fixedly mounted below the U-shaped bracket 21 through a mounting seat 22, and a connecting head 24 is mounted on the output shaft of the gas cylinder 23. A connecting plate 25 is arranged between the connecting head 24 and the pressing roller 28. As shown in Figure 3 and Figure 4 , a rotating shaft 26 is fixedly mounted on the connecting plate 25 between the pressing roller 28 and the connecting head 24 in the embodiment. The connecting plate 25 can be deflected and installed in the mounting hole 211 of the U-shaped bracket 21 through the rotating shaft 26. In order to conveniently adjust the distance between the pressing roller 28 and the supporting roller 29, one end of the connecting plate 25 is rotatably mounted on the connecting head 24, and the other end is rotatably mounted on the pressing roller 28. The height of the pressing roller 28 can be adjusted through the extension and retraction of the output shaft of the gas cylinder 23.
