[0002] The yarn guiding structure of a doubling machine (or also called a parallel winding machine) is one of its key components, mainly used to guide the yarn to a suitable position for doubling operation. The yarn guiding structure of a doubling machine mainly includes parts such as a yarn guiding device, a doubler, and a traversing yarn guide. These parts work together to ensure that the yarn can be accurately and stably guided to the doubler, and then the merging and processing of the yarn are realized.

[0003] Upon inquiry, the publication number: CN206902329U discloses a new type of yarn guiding structure for core-spun yarn. This technology discloses that "it includes a guide screw rod support foot, a filament yarn frame support foot, and a mounting bracket. The guide screw rod support foot and the filament yarn frame support foot are both installed at the bottom of the mounting bracket of the core-spun yarn spinning machine. The guide screw rod support foot is located outside the filament yarn frame support foot; the guide screw rod support foot is a right-angled L-shaped structure, and the opening of the guide screw rod support foot faces inward. The filament yarn frame support foot is an L-shaped structure with an included angle of 60 - 80 degrees, and the opening of the filament yarn frame support foot faces outward. There are two groups of filament yarn frames and they are installed on the filament yarn frame support feet. The mounting plate of the filament yarn frame is fixedly connected to the filament yarn frame support foot, and the screw rod of the filament yarn frame is perpendicularly arranged downward on the side where the filament yarn frame support foot faces downward; the structure of the present utility model is reasonably designed, the installation structure is simple, it is convenient to use and easy to maintain, and it reduces the production cost of the enterprise under the condition of ensuring normal production".

[0004] Regarding the above related technologies, the inventor believes that when the existing yarn guiding structures of doubling machines guide the yarn, most of the yarn guiding structures of doubling machines cannot make the yarn bobbin rotate smoothly, resulting in the situation that the yarn bobbin is easily stuck when the yarn guiding structure of the doubling machine guides the yarn. Moreover, when the yarn guiding structure of the doubling machine guides the yarn, most of the yarn guiding structures of doubling machines cannot adjust the yarn guiding distance, resulting in insufficient tension of the yarn, prone to forming loops, and causing the yarn to knot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is combined with the attached Figure 1 - attachedFigure 3 , the present application will be further described in detail.

[0031] Embodiment

[0032] A yarn guiding structure for a yarn doubling machine, referring to Figure 1 and Figure 2 , includes a chassis 1, a rotating mechanism 2, and a yarn guiding mechanism 3. Two rotating mechanisms 2 are provided at the upper end of the chassis 1. The rotating mechanism 2 is used to place the yarn bobbin and rotate smoothly. The yarn guiding mechanism 3 is installed at the lower end of the chassis 1, and the yarn guiding mechanism 3 can adjust the tension of the yarn.

[0033] Referring to Figure 2 , the rotating mechanism 2 includes a base 20, a bearing 21, a rotating rod 22, a limiting plate 25, and a support rod 23. A bearing 21 is provided inside the base 20. The bearing 21 can ensure that the structure rotates smoothly. The inner surface of the bearing 21 is fixedly welded with a rotating rod 22. The upper end of the rotating rod 22 is fixedly welded with a limiting plate 25. The limiting plate 25 is a conical structure and can limit yarn bobbins with different inner diameters. The support rod 23 is fixedly welded to the limiting plate 25, and the support rod 23 can prevent the yarn bobbin from detaching from the rotating mechanism 2.

[0034] Referring to Figure 2 , three fixing holes 4 are opened on one side of the chassis 1. The fixing holes 4 are equally spaced, which can make the chassis 1 more stable when fixed. Six mounting holes 27 are opened on both sides of the upper end of the chassis 1 and the upper ends of the two bases 20. The mounting holes 27 are annularly distributed, which can stably fix the base 20 to the chassis 1.

[0035] Referring to Figure 2 , a plurality of limiting grooves 24 are opened on the outer surfaces of the two limiting plates 25. The limiting grooves 24 are annularly distributed, which can increase the friction coefficient of the lower end of the yarn bobbin, and thus better limit it.

[0036] Referring to Figure 2 , rotating grooves 26 are opened on the upper ends of the two bases 20. The base 20 can be fixed to the outer surface of the bearing 21 through the rotating grooves 26.

[0037] Referring to Figure 3 , the yarn guiding mechanism 3 includes a primary yarn guiding frame 30, a threaded rod 31, a nut 33, a secondary yarn guiding frame 34, a yarn guiding rod 35, and a yarn guiding hole 36. Two threaded rods 31 are rotatably arranged on the upper inner wall of the primary yarn guiding frame 30. The lower ends of the two threaded rods 31 are fixedly welded with nuts 33. The nuts 33 can facilitate the rotation of the threaded rods 31. A secondary yarn guiding frame 34 is jointly arranged on the outer surfaces of the two threaded rods 31. Two yarn guiding rods 35 are fixedly welded to one side of the primary yarn guiding frame 30 and the secondary yarn guiding frame 34. Yarn guiding holes 36 are opened at the upper ends of the four yarn guiding rods 35, and the yarn guiding holes 36 can guide the yarn through.

[0038] Reference Figure 3 , two yarn guide grooves 5 are opened at the upper end of the chassis 1, so that the yarn guide holes 36 can pass through the yarn guide grooves 5 for yarn guiding after guiding the yarn.

[0039] Reference Figure 3 , two threaded grooves 32 are opened at the upper end of the secondary yarn guide frame 34, so that the threaded rod 31 can drive the secondary yarn guide frame 34 to move up and down through the threaded grooves 32.

[0040] The implementation principle of the embodiment of the present application is as follows: By the rotating mechanism 2, the yarn bobbin is sleeved outside the support rod 23, so that the lower end of the yarn bobbin can contact the limiting groove 24 on the limiting plate 25, thereby limiting the yarn bobbin. When yarn guiding starts, the yarn bobbin will drive the rotating rod 22 and the bearing 21 under the limiting plate 25 to rotate in the rotating groove 26 of the base 20. The bearing 21 can maintain smooth rotation through the internal balls. The base 20 can be fixed to the chassis 1 through the mounting holes 27, and the chassis 1 can be installed through the fixing holes 4, so as to achieve the purpose that the yarn guiding structure of the doubling machine can make the yarn bobbin rotate smoothly.

[0041] Through the yarn guiding mechanism 3, the nut 33 can drive the threaded rod 31 at the lower end of the primary yarn guide frame 30 to rotate, so that the secondary yarn guide frame 34 can move up and down on the outer surface of the threaded rod 31 through the threaded grooves 32, thereby adjusting the distance between the primary yarn guide frame 30 and the secondary yarn guide frame 34. When the yarn passes through the yarn guide holes 36 on the yarn guide rod 35, the tension of the yarn can be adjusted to avoid the situation of yarn knotting. After the yarn passes through the yarn guide holes 36, it can be used in cooperation with the yarn guide grooves 5 and the rotating mechanism 2, so as to achieve the purpose that the yarn guiding structure of the doubling machine can adjust the yarn guiding distance.

The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
