Description

Technical Field

[0001] This utility model relates to the technical field of bundled carbon fiber production equipment, and in particular to a low-friction, anti-snagging U-shaped guide device for carbon fiber yarn frames. Background Technology

[0002] Carbon fiber is a high-performance material widely used in aerospace, automotive, and sporting goods industries. In the production of bundled chopped carbon fiber, a yarn frame is used to support and guide the carbon fiber bundle. However, most existing guide devices are hollow circular hole type, which has several problems after long-term operation: the friction between the hollow circular hole guide device and the carbon fiber bundle is relatively large due to the difficulty in adjusting the angle, easily leading to lint, pilling, and even breakage of the carbon fiber, affecting product quality and production efficiency. Severe lint requires continuous manual cleaning, and if not cleaned in time, a vicious cycle occurs, leading to more and more lint or the lint being carried away by the carbon fiber bundle, resulting in excessive lint in downstream processes and affecting production. Furthermore, the existing guide devices have fixed positions and cannot be flexibly adjusted, making it difficult to adapt to the guiding requirements of different bundle directions.

[0003] Therefore, it is of great significance to study a low-friction, anti-snagging U-shaped guide device for carbon fiber yarn frames to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-friction, anti-snagging U-shaped guide device for carbon fiber yarn frames, thereby solving one or more of the aforementioned problems in the prior art.

[0005] This utility model provides a low-friction, anti-lint U-shaped yarn guide device for carbon fiber yarn frames, comprising:

[0006] A yarn frame, wherein one side of the yarn frame has a crossbeam fixed to the yarn frame;

[0007] The guide wire unit includes a slot, a U-shaped guide wire head, a round vertical rod, and a base. Two screw holes are provided on each side of the slot, and the slot is fixed to the crossbeam by screws. The base is adapted to fit into the slot and can slide left and right along the length of the slot. The bottom end of the round vertical rod is fixedly connected to the base, and the top end is fixedly connected to the U-shaped guide wire head. The inner sidewall of the U-shaped guide wire head is a smooth arc surface, and the two edges of the open end are rounded.

[0008] In some implementations, the slot is an inverted T-shaped groove structure with an internal hollowed-out design. The base and the round vertical rod form an inverted T-shaped structure that matches the size of the slot. The base and the round vertical rod are connected by threads.

[0009] In some embodiments, the U-shaped guide wire tip is made of zirconia ceramic, and the base is made of high-strength nylon.

[0010] In some implementations, the number of guide wire units in the slot is 4-8, which is adjusted according to the number of carbon fiber bundles.

[0011] In some embodiments, the crossbeam is made of steel and has a chrome-plated surface.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) The smooth arc surface and rounded corner design of the U-shaped guide head effectively reduces the friction and lint on the carbon fiber bundle;

[0014] (2) By sliding the base in the slot, the position of the guide wire can be flexibly adjusted. It can be adjusted left and right according to the direction of the carbon fiber bundle to avoid the carbon fiber bundle running angle being too large.

[0015] (3) The slot is fixed by screws, which makes it easy to install and modify existing yarn frames. The overall structure is simple and practical. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0023] like Figure 1-2 As shown, a low-friction, anti-snagging U-shaped yarn guide device for carbon fiber yarn frames includes a yarn frame 1 and a crossbeam 11 fixed to the yarn frame 1. The crossbeam 11 is made of steel with a chrome-plated surface to enhance wear resistance and corrosion resistance. The yarn guide unit 2 is fixed to the crossbeam 11 via a slot 21.

[0024] like Figure 3 As shown, the guide wire unit 2 includes a slot 21, a U-shaped guide wire head 22, a round vertical rod 23, and a base 24. Two screw holes 25 are provided on each side of the slot 21, and the slot 21 is fixed to the crossbeam 11 by screws. The slot 21 is an inverted T-shaped groove structure with an internal hollowed-out design. The base 24 and the round vertical rod 23 form an inverted T-shaped structure, and their dimensions match those of the slot 21, allowing the base 24 to engage within the slot 21 and slide left and right along its length. The base 24 and the round vertical rod 23 are connected by threads for easy disassembly and replacement.

[0025] The U-shaped guide wire head 22 is fixed to the top of the round vertical rod 23. Its inner sidewall is a smooth arc surface, and the two sides of the opening end are rounded (e.g., Figure 4 (As shown), to reduce the risk of friction and lint on the carbon fiber bundles. The U-shaped guide head 22 is made of zirconia ceramic, which has high hardness, low coefficient of friction and wear resistance; the base 24 is made of high-strength nylon, which is lightweight and wear-resistant.

[0026] In practical applications, 4-8 guide units 2 are installed in the slot 21, depending on the number of carbon fiber bundles. The position of the U-shaped guide head 22 can be flexibly adjusted via the sliding base 24 to adapt to different carbon fiber bundle guide paths, reducing the angle of the carbon fiber bundle's movement and thus reducing friction between the carbon fiber and the guide unit 2. During installation, the slot 21 is simply fixed to the crossbeam 11 with screws to complete the modification, making it suitable for existing yarn frames.

[0027] In summary, the low-friction, anti-lint U-shaped guide device for carbon fiber yarn frames provided by this utility model has the following advantages:

[0028] (1) The smooth arc surface and rounded corner design of the U-shaped guide head effectively reduces the friction and lint on the carbon fiber bundle;

[0029] (2) By sliding the base in the slot, the position of the guide wire can be flexibly adjusted. It can be adjusted left and right according to the direction of the carbon fiber bundle to avoid the carbon fiber bundle running angle being too large.

[0030] (3) The slot is fixed by screws, which makes it easy to install and modify existing yarn frames. The overall structure is simple and practical.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
