[0002] Ring spinning technology is the most widely used spinning technology at home and abroad, and twisting is an important link in short-fiber spinning. In this process, the yarn output by the front roller passes through the yarn guide hook, passes through the steel wire ring riding on the edge of the steel collar, and is tightly wrapped around the bobbin of the spindle. When the spindle rotates, the steel wire ring rotates along the steel collar due to the tension of the yarn, and the yarn thus gains twist.

[0003] According to the patent number: CN216514321U, the utility model patent application with the publication date of 2022-05-13 discloses a single-wheel twisting spinning device, including gear I, gear II, a guide wheel assembly support plate, a positioning sleeve, a guide belt drum and a yarn guide wheel, characterized in that: the positioning sleeve is fixedly connected to the guide wheel assembly support plate, the positioning sleeve can be fixed on the supporting crossbar, the guide wheel assembly support plate is provided with gear I, gear II, a guide belt drum and a yarn guide wheel, the guide belt drum and gear II are fixedly connected and coaxially rotated, the yarn guide wheel and gear I are fixedly connected and coaxially rotated, the gear I and gear II are meshed and driven, and the rotation of the guide belt drum can be driven by gear I and gear II to drive the yarn guide wheel to rotate. Its main technical effect is: adding a twister at the yarn guide hook improves the structure of the yarn guide twisting zone, reduces the yarn torque, and spins soft yarn or ply (siro) with low twist.

[0023] Specifically, the specific structure of the protective shell 1 is the prior art and will not be described in detail here. A yarn guide transmission mechanism 2 is arranged inside the protective shell 1, a yarn wheel mounting seat 11 is arranged on the protective shell 1, a mounting groove 31 is opened on the circumferential outer wall of the yarn guide wheel 3, and the dustproof rubber ring 4 includes a connecting portion 41 and a dustproof portion 42, such as Figure 4 As shown, specifically, a limiting groove 43 is opened inside the connecting part 41, and the inner diameter of the connecting part 41 is matched with the inner diameter of the mounting groove 31, so that the connecting part 41 of the dustproof rubber ring 4 can be sleeved on the mounting groove 31, and the bottom of the yarn guide wheel 3 is embedded in the limiting groove 43, which can ensure that the dustproof rubber ring 4 can be firmly installed on the yarn guide wheel 3. Furthermore, the inner diameter of the dustproof part 42 of the dustproof rubber ring 4 is matched with the outer diameter of the yarn wheel mounting seat 11, so that the dustproof part 42 can fit on the outer wall of the yarn wheel mounting seat 11, thereby blocking the gap between the yarn guide wheel 3 and the yarn wheel mounting seat 11, and preventing the floating yarn from entering the yarn wheel mounting seat 11.

[0024] In the utility model, the yarn guide wheel 3 is rotatably connected to the yarn wheel mounting seat 11, and the dustproof rubber ring 4 is installed on the yarn guide wheel 3. The connecting part 41 of the dustproof rubber ring 4 abuts against the yarn guide wheel 3 through the limiting groove 43. The dustproof part 42 of the dustproof rubber ring 4 can be attached to the outer wall of the yarn wheel mounting seat 11, so that the gap between the yarn guide wheel 3 and the yarn wheel mounting seat 11 can be blocked, and the floating yarn on the yarn can be prevented from entering the inside of the yarn guide wheel 3. The spinning efficiency can be guaranteed during the spinning process, and the floating yarn can be prevented from reducing the transmission efficiency, thereby extending the service life of the false twist spinning device and reducing the production cost.

[0025] As an embodiment provided by the utility model, Figure 2 and Figure 3 As shown, the yarn guide transmission mechanism 2 includes a first gear 21 and an orthogonal connecting screw 22. The first gear 21 is fixedly mounted on the circumferential outer wall of the orthogonal connecting screw 22. A connecting bearing 23 is arranged on the outer wall of the orthogonal connecting screw 22. The orthogonal connecting screw 22 is rotatably connected to the yarn wheel mounting seat 11 through the connecting bearing 23. A nut groove is provided on the top of the yarn guide wheel 3.
