[0003] The winding machine of the prior art is shown in the utility model patent of the People's Republic of China No. 201920065286.X. After the yarn is unwound by the active unwinding device, it passes through the conveying of the overfeed device, the tension is adjusted by the tension adjusting device, the yarn is moved left and right by the yarn guiding device, and the yarn bobbin is driven by the yarn guiding roller device, and finally wound and formed by the winding device. However, the above winding machine often has the following defects in actual use:

[0004] 1. The surface of the unwound yarn is relatively rough and has poor smoothness, which is not conducive to subsequent weaving use.

[0005] 2. The winding device is arranged horizontally, and the clamping and removal of the yarn rack both have limited operating space, and the horizontal dimension of the equipment becomes larger.

[0012] The winder with drafting rollers of the present utility model is also configured as follows: A friction roller is pivotally connected to the yarn guiding device, and the friction roller can be in contact with the active winding device.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. By arranging two drafting rollers in the winder of the present utility model, with one drafting roller running faster and the other slower, the yarn is cold-drafted between the two drafting rollers, making the surface of the yarn smooth and compliant, improving the quality of the yarn, and facilitating subsequent weaving use.

DETAILED DESCRIPTION

[0019] Please refer to the attached drawings Figure 1 to Figure 3 As shown, the present utility model is a winder with drafting rollers, which is composed of a frame 1, a yarn rack 2, a first drafting roller 3, a second drafting roller 4, a tension sensor 5, a yarn guiding device 6, an active winding device 7, etc.

[0020] Among them, the yarn rack 2, the first drafting roller 3, the second drafting roller 4, the tension sensor 5, the yarn guiding device 6, and the active winding device 7 are sequentially installed on the frame 1 from bottom to top.

[0021] The yarn rack 2 is located at the bottom of the frame 1 and is vertically arranged. The raw yarn 91 is placed on the yarn rack 2 and unwound.

[0022] A driving motor 10 is respectively installed on the first drafting roller 3 and the second drafting roller 4, and the first drafting roller 3 and the second drafting roller 4 are independently driven by the driving motor 10. Moreover, the rotational speed of the driving motor 10 for driving the second drafting roller 4 is greater than the rotational speed of the driving motor 10 for driving the first drafting roller 3, so that the yarn 92 is cold-drafted between the two drafting rollers 3 and 4, making the surface of the yarn smooth and compliant, improving the quality of the yarn, and facilitating subsequent weaving use. Of course, when the winder of the present utility model is actually used, the rotational speeds of the first drafting roller 3 and the second drafting roller 4 can be arbitrarily adjusted to achieve different drafting ratios. Even the rotational speed of the first drafting roller 3 is greater than that of the second drafting roller 4 to meet different requirements.

[0023] In this embodiment, the first drafting roller 3 and the second drafting roller 4 have the same structure, and both include a roller 31 and a yarn splitting roller 32. The driving motor 10 drives the roller 31 to rotate actively, thereby realizing the conveying of the yarn 92. There is an included angle between the axis of the yarn splitting roller 32 and the axis of the roller 31, so that the yarn 92 can be wound around the roller 31 dispersedly, avoiding the stacking of the yarn.

[0024] Furthermore, a tensioner 11 is provided between the yarn creel 1 and the first drafting roller 3. The tension of the yarn is adjusted by the tensioner 11, and the tension of the yarn is detected by the tension sensor 5, and the two cooperate with each other to meet the requirements of the production process.

[0025] The yarn guiding device 6 is used to guide the yarn 92 onto the yarn bobbin 93, so that the yarn covers the yarn bobbin 93. A friction roller 61 is pivotally connected to the yarn guiding device 6, and the friction roller 61 can abut against the active winding device 7 and can press against the yarn.

[0026] The active winding device 7 is pivotally connected to the frame 1. When winding, it rotates to one side of the yarn guiding device 6. It includes a winding main shaft 71 and a winding motor 72. The winding main shaft 71 is arranged in the front-rear direction and is driven by the winding motor 72 to rotate. The yarn bobbin 93 is installed on the winding main shaft 71 and is driven by the winding main shaft 71.

[0027] The working principle of the winder with drafting rollers of the present utility model is as follows: The raw yarn 91 is placed on the yarn creel 2. The yarn 92 is unwound from the raw yarn 91 and enters the tensioner 11, and the tension of the yarn 92 is adjusted by the tensioner 11. Then the yarn 92 passes through the first drafting roller 3 and the second drafting roller 4 in sequence. Since the rotational speed of the second drafting roller 4 is greater than that of the first drafting roller 3, the yarn 92 is cold-drafted between the two drafting rollers 3 and 4, making the surface of the yarn smooth and compliant. Then the tension of the yarn 92 is detected by the tension sensor 5 to meet the requirements of the production process. Finally, the yarn is guided by the yarn guiding device 6 and wound by the active winding device 7, and finally wound into a yarn bobbin 93.

[0028] The above specific embodiments are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present creation shall be included within the protection scope of the present creation.
