[0002] The function of a yarn drawing machine is to evenly wind different raw materials onto a spinning head for use on the machine. According to the spinning process, combing is an important step in the yarn drawing machine and is the foundation of its processing. It requires combing multiple groups of raw material fibers.

[0003] Chinese Patent CN207276813U discloses a combing mechanism on a combing machine. The combing mechanism is disposed inside a combing frame, which includes a lower base and an upper base hinged to the lower base. The combing mechanism includes a combing process component disposed in the lower base, a combing reset component disposed in the upper base, multiple combs circulating between the combing process component and the combing reset component, a first upper component connecting the end of the combing process component to the beginning of the combing reset component, and a second upper component connecting the end of the combing reset component to the beginning of the combing process component. Through the cooperation between the combing process component, the combing reset component, the first upper component, and the second upper component, the combs can be rapidly circulated, enabling efficient and rapid combing of fibers, thereby greatly improving combing efficiency.

[0004] However, in the above technical solution, during the yarn drawing process, the yarn also needs to pass through the yarn guide plate and the yarn guide roller.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a yarn combing device for a yarn drawing machine, the yarn combing device of the yarn drawing machine includes: a yarn drawing machine body 1, an electric push rod 2 is provided at the bottom of the yarn drawing machine body 1, a lifting plate 3 is provided at the lifting end of the electric push rod 2, a positioning plate 4 is provided on the side of the lifting plate 3; a guide plate 5, a lifting groove 6 is opened on the surface of the guide plate 5, a positioning frame 7 is provided in the lifting groove 6, a first bearing 8 is provided on the inner surface of the positioning frame 7, a rotating rod 9 is provided on the inner ring surface of the first bearing 8, and a guide wheel 10 is provided on the end face of the rotating rod 9;

[0022] When it is necessary to guide the yarn, the yarn can first be passed through the positioning frame 7 so that the yarn is located between the two sets of guide wheels 10. The yarn is then guided by the two sets of guide wheels 10. In addition, the rotation of the two sets of guide wheels 10 reduces the friction between the surface of the guide wheels 10 and the yarn, thereby reducing the problem of damage during yarn guidance.

[0023] Example 2: Based on Example 1, guide wheels 10 are provided to facilitate the guidance of yarn. Lifting plate 3 is fixedly connected to the lifting end of electric push rod 2. Guide plate 5 is fixedly connected to the surface of positioning plate 4 with bolts. A third bearing 16 is sleeved on the outer surface of guide wheel 10.

Multiple sets of lifting grooves 6 are provided. The multiple sets of lifting grooves 6 are linearly arranged at equal intervals about the surface of guide plate 5. Threaded holes are provided on the surface of lifting groove 6. Lifting screws 11 are screwed into the threaded holes.

[0024] In use, the height of the guide plate 5 can be adjusted by the electric push rod 2 to facilitate the adjustment of the yarn height. Then, the yarn is passed between the two sets of guide wheels 10, so that the yarn is guided by the two sets of guide wheels 10 in conjunction with the positioning frame 7. The two sets of guide wheels 10, in conjunction with the third bearing 16, can make the outer surfaces of the two sets of guide wheels 10 in contact without affecting the rotation of the two sets of guide wheels 10. In addition, the rotation of the guide wheels 10 can reduce the friction on the yarn.

This allows for height adjustment to accommodate different yarns. Additionally, the positioning frame 7 can be moved along the guide rod 14, and the positioning spring 15 can provide tension to the positioning frame 7. Furthermore, when the yarn is taut, the positioning frame 7 can be moved along the guide rod 14 to reduce hard contact with the yarn, thus providing protection for the yarn.
