Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber technology, specifically, it relates to a carbon fiber take-up guide roller device. Background Technology

[0002] Carbon fiber is a novel, high-performance organic fiber characterized by high strength, high modulus, high electrical conductivity, chemical resistance, and high temperature resistance. As an advanced structural and functional material, it is widely used in aerospace, wind turbine blades, sporting goods, and building materials. Due to its numerous excellent properties, carbon fiber has become a research hotspot, and in recent years, it has experienced widespread and rapid development.

[0003] Carbon fiber winding is the final step in carbon fiber processing. It involves guiding the prepared carbon fibers onto a drum via guide rollers for winding, thus achieving the purpose of winding. Existing technology has the following drawbacks: During carbon fiber winding, as production demands increase, the number of carbon fiber bundles increases, leading to insufficient length of individual guide rollers. This causes the carbon fiber bundles to overlap and fall off the rollers, affecting product quality and production efficiency.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] like Figure 1As shown, this utility model provides a take-up guide roller device, including a frame 1, and further including:

[0053] The first guide roller 2 is mounted on the frame 1;

[0054] At least one second guide roller 3 is disposed above or below the first guide roller 2;

[0055] The second guide roller 3 extends along the axial direction of the first guide roller 2 and is arranged at a distance from the first guide roller 2 in the radial direction.

[0056] In this embodiment of the invention, by increasing the number of guide rollers and setting the upper and lower guide rollers with a radial gap, multiple carbon fiber bundles 8 can run separately on different guide rollers to the take-up machine for take-up. This separate running method effectively avoids bundle overlap and roller drop, improves the stability of bundle running, and increases product quality and production efficiency.

[0057] The second guide roller 3 and the first guide roller 2 are arranged with a radial gap between them, which allows the multiple carbon fiber bundles 8 to be separated more thoroughly when they are directed to different guide rollers, thus preventing the multiple carbon fiber bundles 8 from tangling together. For example, as Figure 1 As shown, when the second guide roller 3 is located below the first guide roller 2, the axial direction of the first guide roller 2 is left-right, and the radial direction of the first guide roller 2 is front-back. The first guide roller 2 can be in front of the second guide roller 3, or the second guide roller 3 can be in front of the first guide roller 2.

[0058] In an embodiment of this utility model, two second guide rollers 3 are arranged at intervals along the axial direction of the first guide roller 2 below the first guide roller 2.

[0059] In the embodiments of this utility model, the two second guide rollers 3 are arranged at intervals to make full use of the space on the frame 1;

[0060] When guiding the filament, the filament moves from bottom to top and is divided into three columns. One column of filament runs on the first guide roller 2, and the other two columns run on the two guide rollers respectively.

[0061] The first guide roller 2 is horizontally fixed in the middle of the frame 1. The length of the first guide roller 2 is greater than that of the second guide roller 3. As the main guide roller of the filament, it bears the main tension transmission. The two second guide rollers 3 are uniformly located below the first guide roller 2. They are shorter in length and serve as auxiliary guide rollers of the filament, forming a three-roller structure of "one on top and two on the bottom".

[0062] The second guide roller 3 is set at one end not exceeding the axial direction of the first guide roller 2. Specifically, the two second guide rollers 3 are guide roller one and guide roller two. The two second guide rollers 3 have the same shape and size. Guide roller one and guide roller two are arranged left and right. Guide roller one is to the left of guide roller two. The left end of guide roller one does not exceed the left end of the first guide roller 2. The right end of guide roller one and the left end of guide roller two are spaced apart. The right end of guide roller two does not exceed the right end of the first guide roller 2.

[0063] like Figure 1 and 2 As shown in the embodiment of this utility model, the second guide roller 3 can rotate on the horizontal plane so that the second guide roller 3 can switch between the initial position and the rotating position;

[0064] When the second guide roller 3 is in the initial position, the second guide roller 3 is parallel to the first guide roller 2;

[0065] When the second guide roller 3 is in the rotating position, the second guide roller 3 is no longer parallel to the first guide roller 2.

[0066] In this embodiment of the present invention, the first guide roller 2 is located in the middle of the frame 1 and serves as the main guide roller, ensuring that the direction of the filament bundle is aligned with the take-up machine. The two second guide rollers 3 are not located in the middle of the frame 1 relative to the first guide roller 2. During guidance, the direction of the carbon fiber filament bundle 8 may not be aligned with the take-up machine, resulting in the inability to take up the filaments normally. In order to achieve flexible control over the direction of the carbon fiber filament bundle 8 and ensure that the direction of the carbon fiber filament bundle 8 is aligned with the take-up machine, the rotation angle of the second guide roller 3 on the horizontal plane can be adjusted to improve the adaptability of the production process.

[0067] When the second guide roller 3 is in the initial position, it is parallel to the first guide roller 2 and can guide the carbon fiber bundle 8 in an orderly manner. When the second guide roller 3 is in the rotating position, it is no longer parallel to the first guide roller 2 and can change the direction of the carbon fiber bundle 8 passing through the second guide roller 3.

[0068] like Figure 3 and 4 As shown in the embodiment of this utility model, the second guide roller 3 is supported on the frame 1 by the rotating frame 4;

[0069] The two ends of the second guide roller 3 are fixedly supported on the rotating frame 4, and rotate around its own axis on the rotating frame 4;

[0070] The rotating frame 4 can rotate on the horizontal plane.

[0071] In this embodiment of the present invention, by setting the rotating frame 4, on the one hand, the second guide roller 3 is supported and fixed, so that the second guide roller 3 can rotate around its own axis first to guide the carbon fiber bundle 8; on the other hand, it can drive the second guide roller 3 to rotate on the horizontal plane to change the direction of the carbon fiber bundle 8.

[0072] Specifically, the frame 1 has a first support portion 11 extending axially along the first guide roller 2;

[0073] The rotating frame 4 includes:

[0074] The rotating part 41 extends along the axial direction of the first guide roller 2, fits against the top surface of the first support part 11, and rotates on the first support part 11;

[0075] The second support part 42 is formed by bending one side of the rotating part 41 upwards, and is used to fix and support the second guide roller 3.

[0076] The first support portion 11 extends horizontally, and its top surface is a horizontal plane. The rotating portion 41 extends horizontally and is flat, with its bottom surface being a horizontal plane. The bottom surface of the rotating portion 41 is completely in contact with the top surface of the first support portion 11, so that the rotating portion 41 can rotate stably on the first support portion 11 while rotating on the horizontal plane. The rotating portion 41 can rotate on the first support portion 11 via a rotating shaft, or it can rotate directly in contact with the first support portion 11 without a rotating shaft.

[0077] The second support part 42 is a plate-shaped structure. The two ends of the second guide roller 3 are fixed to the second support part 42 and can rotate around its own axis on the second support part 42.

[0078] Furthermore, when the rotating part 41 rotates into position on the first support part 11, the rotating part 41 is fixed to the first support part 11 by the fixing member 5;

[0079] The fastener 5 can be a screw-type fastener 5, a snap-fit ​​fastener 5, etc.;

[0080] When the fastener 5 is a screw-type fastener 5, the rotating part 41 is provided with a first fixing hole and the first support part 11 is provided with a second fixing hole.

[0081] The fastener 5 includes a bolt and a nut 51; the bolt passes through the first fixing hole and the second fixing hole from top to bottom to the bottom of the first support part 11 and is screwed to the nut 51.

[0082] The centerlines of the first fixing hole and the second fixing hole extend vertically and are coaxially arranged to achieve a stable connection between the rotating part 41 and the first support part 11. The bolt can act as a rotating shaft, allowing the rotating part 41 to rotate around its centerline. When the second guide roller 3 rotates, the bolt and nut 51 are loosened, and the rotating part 41 rotates around the bolt. Alternatively, the bolt can not act as a rotating shaft; when the second guide roller 3 rotates, the bolt and nut 51 are removed from the rotating part 41 and the first support part 11, and the rotating part 41 rotates directly on the first support part 11. Multiple first and second fixing holes can be provided to improve the fixing strength between the first support part 11 and the rotating part 41.

[0083] In this embodiment of the present invention, one end of the second guide roller 3 is fixedly supported on the second support part 42 by the fixing frame 6;

[0084] The second guide roller 3 rotates around its own axis on the fixed frame 6.

[0085] In this embodiment of the present invention, the second guide roller 3 is fixedly supported on the second support part 42 by two fixed frames 6. One end of the second guide roller 3 is fixed on the fixed frame 6 and rotates around its own axis. By fixing the second guide roller 3 on the second support part 42 by the fixed frame 6, the swaying of the second guide roller 3 can be reduced when the rotating part 41 rotates, and the stability of the second guide roller 3 on the frame 1 can be improved.

[0086] Specifically, the mounting bracket 6 includes:

[0087] The third support part 61 is attached and fixed to the side of the second support part 42 that is opposite to the rotating part 41;

[0088] The fixing part 62 is formed by bending one end of the third support part 61 upward, and the fixing part 62 is provided with a third fixing hole 63 for fixing one end of the second guide roller 3.

[0089] The third support part 61 is located on the side of the second support part 42 facing away from the rotating part 41, avoiding the installation of the third support part 61 on the second support part 42 in the area between the rotating part 41 and the second support part 42, thus reducing the installation difficulty of the third support part 61; the third support part 61 and the fixing part 62 are plate-shaped structures, and the third support part 61 is fitted to the second support part 42, which can improve the stability of the fixing frame 6 on the rotating frame; the third support part 61 and the second support part 42 are fixedly connected by bolts and nuts 51; preferably, the fixing part 62 and the third support part 61 are arranged vertically.

[0090] The fixing part 62 is provided with a plurality of third fixing holes 63 arranged in the vertical direction, which can adjust the height of the second guide roller 3. The fixing holes are coaxial with the second guide roller 3. Specifically, when the second guide roller 3 is installed, one end of the second guide roller 3 is passed through one side of the fixing hole of one fixing part 62 to the other side and fixedly connected to the fixing part 62. The other end of the second guide roller 3 is passed through one side of the fixing hole of another fixing part 62 to the other side and fixedly connected to the fixing part 62, so that the second guide roller 3 is located between the two fixing parts 62.

[0091] Furthermore, the second support portion 42 gradually tilts from bottom to top toward one side of the rotating portion 41 and one side of the first support portion 11;

[0092] The fixing part 62 gradually tilts from bottom to top toward the other side of the first support part 11, and tilts until it protrudes from the first support part 11;

[0093] Multiple fixing holes are provided on the fixing part 62 that protrudes from the first support part 11.

[0094] With the above arrangement, a clearance area can be formed between the fixing part 62 and the first support part 11 to prevent the carbon fiber bundle 8 moving from bottom to top from hitting the first support part 11 and rubbing against the first support part 11, so that there is a gap between the carbon fiber bundle 8 and the first support part 11 during the movement.

[0095] Furthermore, the second support portion 42 includes two first sections 421 distributed along the axial direction of the first guide roller 2 and a second section 422 located between the two first sections 421;

[0096] The first segment 421 is tilted relative to the second segment 422, closer to the rotating part 41, so that a gap 423 is formed between the first segment 421 and the second segment 422;

[0097] The third support part 61 is fitted and fixed to the first section 421;

[0098] The first support part 11 and the rotating part 41 are bound together by the binding member 7 through the through-slit 423.

[0099] Two slits 423 are formed on the second support part 42. One first section 421 is used to fix one end of the second guide roller 3, and the other first section 421 is used to fix the other end of the second guide roller 3.

[0100] The binding element 7 can be a steel wire 71, a binding rope, etc. When the binding element 7 is a steel wire 71, the steel wire 71 passes through the slit 423 and is inserted into the bottom of the slit 423. The two ends of the steel wire 71 extend to both sides of the slit 423 and extend downward to wrap around the rotating part 41 and the first support part 11 respectively. At the bottom of the first support part 11, the two ends of the steel wire 71 rope converge and are tied together to bind the first support part 11 and the rotating part 41 tightly, thereby further improving the stability of the second guide roller 3 on the frame 1.

[0101] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
