Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber production equipment, and in particular to an anti-friction carbon fiber yarn frame with obliquely arranged guide holes. Background Technology

[0002] In the carbon fiber textile processing, the yarn frame is a key piece of equipment for the stable guidance of carbon fiber filaments. In existing technologies, the yarn guide structure of carbon fiber yarn frames generally has design flaws: the guide holes on the side of the yarn frame are arranged in multiple horizontal layers, and the guide holes are simple cylindrical hollow structures.

[0003] This design leads to two core problems: First, the multi-layered horizontally arranged guide holes result in extremely small lateral spacing between the preceding and following carbon fiber bundles when they pass through the holes, making them prone to contact, scraping, or even entanglement, causing damage to the bundle surface and directly affecting the strength and quality of subsequent products. Second, the cylindrical hollow structure of the guide holes has a straight inner wall, resulting in hard friction with the carbon fiber bundles. When the bundles enter and exit the holes, the edges are prone to scraping against the hole walls, further aggravating bundle wear, leading to more lint buildup in the guide holes, increasing material loss during production, and reducing production efficiency.

[0004] Therefore, it is of great significance to study a friction-resistant carbon fiber yarn frame with obliquely arranged guide holes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a friction-resistant carbon fiber yarn frame with obliquely arranged guide holes, thereby solving one or more of the aforementioned problems in the prior art.

[0006] This utility model provides an anti-friction carbon fiber yarn frame with obliquely arranged guide holes, comprising:

[0007] Main body of the yarn frame;

[0008] A rectangular support plate is fixed to the side of the yarn frame body. Guide holes are opened on the rectangular support plate from top to bottom along its own diagonal direction.

[0009] Each of the aforementioned guide wire holes can be detachably installed with a guide wire unit.

[0010] In some implementations, the guide wire holes are distributed in a "higher inside, lower outside" pattern, with the guide wire holes closer to the inner side of the yarn frame body being at a higher position and the guide wire holes further away from the inner side of the yarn frame body being at a lower position.

[0011] In some implementations, the tilt angle θ of the guide wire hole position on the rectangular support plate, which is "higher inside and lower outside", is 15° to 40°.

[0012] Wherein: the tilt angle is measured by the angle between the guide wire hole axis and the horizontal plane.

[0013] In some implementations, the guidewire unit is composed of two symmetrical halves joined together, forming a structure with trumpet-shaped ends and an arc-shaped channel in the middle; each half has a radially protruding locking block on its outer side.

[0014] In some implementations, after the guidewire unit is engaged, the outer edges of its two flared structures are provided with anti-slip texture.

[0015] In some embodiments, the guide wire hole on the rectangular support plate is an irregularly shaped hole, and an L-shaped groove is provided on the hole wall corresponding to the position of the locking block. After the locking block is inserted into the L-shaped groove and rotated 90°, the guide wire unit can be locked in the guide wire hole.

[0016] In some embodiments, the guide wire unit is made of ceramic, zirconium oxide, or a wear-resistant polymer material.

[0017] In some embodiments, the rectangular support plate is detachably mounted to the side of the yarn frame body by bolts.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) By arranging the guide holes obliquely, a stable spacing is formed between the carbon fiber bundles, which completely solves the problem of bundle contact and entanglement caused by the traditional horizontal arrangement and reduces the surface damage rate of the bundles.

[0020] (2) Through the design of special guide channels, the carbon fibers can enter and exit smoothly in the guide holes, and the hard friction is reduced. The dual effect reduces the wear of the fiber bundle and reduces the lint.

[0021] (3) The convenient disassembly and assembly improves maintenance efficiency, shortens maintenance time and effectively improves production efficiency compared with traditional fixed structures. Attached Figure Description

[0028] 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.

[0029] 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.

[0030] like Figure 1 , Figure 2 As shown, this is an anti-friction carbon fiber yarn frame with obliquely arranged guide holes, mainly comprising a yarn frame body 1, a rectangular support plate 2, and a guide unit 3. The yarn frame body 1 is made of welded steel to ensure overall structural stability. The rectangular support plate 2 is made of aluminum alloy or high-strength engineering plastic and is fixed to the side of the yarn frame body 1 by bolts 4. The guide holes on the rectangular support plate 2 are sequentially opened from top to bottom along its diagonal, and the angle between the axis of the holes and the horizontal is preferably 15°-40°, so as to prevent the front and rear carbon fibers from contacting and rubbing against each other during operation.

[0031] like Figure 3 , Figure 4 , Figure 5 As shown, the guide wire unit 3 is preferably made of ceramic or zirconium oxide, which helps to keep the inner wall of the guide wire channel smooth for a long time and avoids scratching the carbon fiber bundle. The mating surfaces of the two halves 31 of the guide wire unit 3 are precision machined to ensure that there is no misalignment or burr on the inner wall of the guide wire channel 32 after mating. The diameter of the flared structure at both ends gradually narrows from the outside to the inside to guide the carbon fiber bundle to be smoothly introduced. Each half 31 has a locking block 33 on its outer side. The size of the locking block 33 matches the size of the L-shaped slot 21 of the support plate to ensure that the locking block 33 can rotate without jamming after insertion and can be locked without loosening.

[0032] Installation of guide wire unit 3: First, place the two halves 31 on both sides of the support plate 2, align the locking blocks 33 on the outer side of the half 31 with the longitudinal entrance of the L-shaped slot 21 on the support plate 2, and slowly push the half 31 on both sides into place until the locking blocks 33 are completely inserted into the bottom of the longitudinal section of the L-shaped slot 21, so that the two halves 31 form a complete guide wire unit 3. Pinch the anti-slip texture 34 on the outer side of both ends of the guide wire unit 3 and rotate it 90° clockwise, so that the locking blocks 33 slide into the transverse section of the L-shaped slot 21. At this time, the guide wire unit 3 is completely locked and there is no looseness. The installation is complete.

[0033] Disassembly of guide wire unit 3: Pinch the anti-slip texture 34 on the outer side of both ends of guide wire unit 3, rotate 90° counterclockwise, so that the locking block 33 returns to the longitudinal entrance position of the L-shaped locking slot 21, and pull out the guide wire unit 3 to complete the disassembly. No tools are required throughout the process.

[0034] In practical production applications, carbon fiber bundles farther from the support plate 2 pass through the higher guide unit 3 on the support plate 2, while carbon fiber bundles closer to the support plate 2 pass through the lower guide unit 3 on the support plate 2. The bundles travel smoothly along an oblique path, avoiding mutual friction and minimizing damage through the special guide channel. Furthermore, the easy disassembly and assembly of the guide unit allows for quick maintenance, improving overall production quality and efficiency. This carbon fiber yarn frame uses obliquely arranged guide holes to create spatial spacing between the front and rear carbon fiber bundles. Combined with the special guide channel, friction is reduced, and the guide unit is easy to disassemble, effectively reducing carbon fiber bundle damage and improving both product quality and maintenance efficiency.

[0035] In summary, the anti-friction carbon fiber yarn frame with obliquely arranged guide holes provided by this utility model has the following advantages:

[0036] (1) By arranging the guide holes obliquely, a stable spacing is formed between the carbon fiber bundles, which completely solves the problem of bundle contact and entanglement caused by the traditional horizontal arrangement and reduces the surface damage rate of the bundles.

[0037] (2) Through the design of special guide channels, the carbon fibers can enter and exit smoothly in the guide holes, and the hard friction is reduced. The dual effect reduces the wear of the fiber bundle and reduces the lint.

[0038] (3) The convenient disassembly and assembly improves maintenance efficiency, shortens maintenance time and effectively improves production efficiency compared with traditional fixed structures.

[0039] 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.
