Description

Technical Field

[0001] This application relates to the field of carbon fiber production technology, and more specifically, to carbon fiber winding devices and carbon fiber production systems. Background Technology

[0002] In the carbon fiber production process, a winding device is needed to collect the produced carbon fiber tow. Existing winding devices include multiple guide rollers, through which the carbon fiber tow is wound onto a winding shaft. Because the carbon fiber tow travels a relatively long distance from the previous process to the winding device, it is prone to deviation on the guide rollers due to not maintaining a single vertical plane. This can lead to the carbon fiber tow flipping, and if not controlled, will cause problems such as edge overlap, poor twisting, and poor width development. Twisted carbon fiber tow will cause significant inconvenience and waste in subsequent processes, rendering it unusable. Compared to normal carbon fiber tow, twisted carbon fiber tow exhibits inconsistent width, meaning poor width development. In subsequent applications, whether for prepreg or carbon fiber fabrics, noticeable gaps will appear, rendering it unusable. Utility Model Content

[0003] The purpose of this application is to provide a carbon fiber winding device and a carbon fiber production system to reduce the occurrence of carbon fiber bundle flipping and twisting during the winding process.

[0004] The embodiments of this application are implemented as follows:

[0005] In a first aspect, embodiments of this application provide a carbon fiber winding device, including a frame, a first guide wheel assembly disposed on the frame, and a winding shaft.

[0006] The first guide wheel assembly includes a mounting rod, a bearing, and a first guide wheel; the mounting rod includes a first section and a second section connected to each other, the second section being connected to the frame; in the radial direction, the bearing is disposed between the first section and the first guide wheel to allow the first guide wheel to rotate relative to the first section; the carbon fiber tow is wound onto the take-up shaft after passing through the outer circumferential surface of the first guide wheel.

[0007] The bearing has an inner ring with a cavity, and the first segment is located in the cavity and has a gap with the surface of the cavity perpendicular to the axis of the bearing, so that the bearing can rotate relative to the first segment about a direction perpendicular to the axis of the bearing.

[0008] In the above technical solution, the carbon fiber tow can be wound onto a take-up shaft after passing through the first guide wheel. A bearing is provided between the first guide wheel and the first section of the mounting rod, allowing the first guide wheel to rotate. As the carbon fiber tow passes through the first guide wheel, the first guide wheel can rotate under the action of the carbon fiber tow, thereby reducing the friction between the carbon fiber tow and the first guide wheel.

[0009] Because the inner ring of the bearing has a gap with the first section perpendicular to the bearing axis, the bearing can rotate relative to the first section about a direction perpendicular to the bearing axis. Therefore, if the carbon fiber bundle deviates on the first guide wheel, the first guide wheel will also deviate about a direction perpendicular to the bearing axis under the force of the carbon fiber bundle, thereby improving the deviation of the carbon fiber bundle and reducing the occurrence of carbon fiber bundle flipping and twisting during the winding process.

[0010] In some optional embodiments, the cavity has a first arc surface and a second arc surface disposed opposite to each other, and the first segment has a third arc surface and a fourth arc surface disposed opposite to each other; the third arc surface is disposed toward the first arc surface and the fourth arc surface is disposed toward the second arc surface;

[0011] The gap is located between the first arc surface and the third arc surface, and / or between the second arc surface and the fourth arc surface.

[0012] In the above technical solution, the gap that allows the bearing to rotate relative to the first section about a direction perpendicular to the bearing axis is located between the first arc surface and the third arc surface, and / or between the second arc surface and the fourth arc surface. This makes it easier for the first guide wheel to deflect after the carbon fiber bundle deviates, thereby improving the situation where the carbon fiber bundle may flip or twist.

[0013] In some alternative embodiments, the cavity further has a first plane, and the first segment has a second plane, the second plane being disposed toward the first plane to restrict the inner ring of the bearing from rotating about the axis of the bearing relative to the first segment.

[0014] In some alternative implementations, the first, second, third, and fourth arc surfaces are all cylindrical surfaces, and their axes are all perpendicular to the rotation axis of the bearing.

[0015] In the above technical solution, the first, second, third and fourth arc surfaces are all cylindrical surfaces, which makes it easier for the inner ring of the bearing to deflect relative to the first section of the mounting rod. This makes it easier for the first guide wheel to deflect after the carbon fiber bundle deviates, thereby improving the situation where the carbon fiber bundle may flip or twist.

[0016] In some alternative embodiments, the second segment is further provided with a bearing retainer ring, the bearing being configured to contact the bearing retainer ring during relative rotation in a direction perpendicular to its own axis or during movement in a direction along its own axis.

[0017] In the above technical solution, by setting a bearing retaining ring, the angle of deflection of the bearing relative to the first mounting rod can be limited, thereby limiting the angle of deflection of the first guide wheel to avoid the first guide wheel deflecting too much.

[0018] In some alternative embodiments, the frame is further connected to a mounting bracket, the mounting bracket including a base plate; the second section is threaded, one end of the second section is located on one side of the base plate and threaded with a nut, and the other end of the second section is located on the other side of the base plate and threaded with a nut.

[0019] In the above technical solution, the second threaded connection has two nuts, which clamp the base plate to fix the mounting rod to the base plate. Because the second section is threaded, the position of the nuts on the second section can be adjusted, thereby adjusting the distance the first section extends relative to the base plate, and thus adjusting the position of the first guide wheel.

[0020] In some alternative implementations, the base plate is connected to a plurality of the first guide wheel assemblies.

[0021] The above technical solution has multiple first guide roller assemblies, so it can be used to simultaneously wind up multiple carbon fiber bundles.

[0022] In some alternative embodiments, the mounting bracket includes a support plate connected to the frame, the support plate being connected to a base, a main rod being connected between the base and the bottom plate, a first end of the main rod being fixedly connected to the bottom plate, and a second end being rotatable relative to the base, the base being optionally fixedly connected to the second end of the main rod.

[0023] In the above technical solution, since the first end of the main rod is fixedly connected to the base plate and the second end can rotate relative to the base plate, the tilt angle of the base plate can be changed, that is, the angle between the arrangement direction of the multiple first guide wheel assemblies and the horizontal plane can be changed. Since the base can be fixedly connected to the second end of the main rod, the main rod can be fixed by the base after the tilt angle of the base plate is adjusted.

[0024] In some optional embodiments, a second guide wheel and a third guide wheel are further provided between the first guide wheel and the take-up shaft, and the carbon fiber bundle is wound onto the take-up shaft after passing through the first guide wheel, the second guide wheel and the third guide wheel in sequence.

[0025] Secondly, embodiments of this application provide a carbon fiber production system, including a spinning device, a pre-oxidation device, a carbonization device, and a carbon fiber winding device provided in the first aspect, wherein the carbon fiber bundle obtained by the carbonization device enters the carbon fiber winding device from the first guide wheel.

[0026] In the above technical solution, the carbon fiber bundle enters the carbon fiber winding device through the first guide wheel. The first guide wheel can deflect relative to the first section of the mounting rod. When the carbon fiber bundle deviates on the first guide wheel, the first guide wheel will spontaneously flip under the action of the carbon fiber bundle, thereby causing the carbon fiber bundle to shift towards the middle of the first guide wheel, so as to improve the problem of carbon fiber bundle deviating, and thus improve the situation of carbon fiber bundle flipping and twisting.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] The inventors of this application have discovered that in the carbon fiber production process, there is a considerable distance between the winding device used in the winding process and the device used in the previous process. Therefore, it is easy for the carbon fiber bundles to deviate from their intended path on the guide rollers due to not moving in the same vertical plane. Figure 1 As shown, the guide wheel includes a peripheral surface for contacting the carbon fiber bundle and upright plates 231 at both ends of the peripheral surface. In the event of the carbon fiber bundle deviating, the carbon fiber bundle may move to contact the upright plates 231, which may cause the carbon fiber bundle to flip or twist.

[0041] Based on this, the inventors of this application provide a carbon fiber production system, including a spinning device, a pre-oxidation device, a carbonization device, a graphitization device, and a carbon fiber winding device. The carbon fiber tow obtained by the carbonization device enters the carbon fiber winding device from the first guide wheel 230. The spinning device is used to form polyacrylonitrile fibers, the pre-oxidation device is used to pre-oxidize the polyacrylonitrile fibers, and the carbonization and graphitization devices are used to heat the fibers to finally obtain carbon fiber tows. The carbon fiber winding device also includes a winding shaft for collecting the obtained carbon fiber tows on the winding shaft.

[0042] The carbon fiber winding device also includes a first guide wheel assembly 200, such as... Figure 2 and Figure 3 As shown, the first guide wheel assembly 200 includes a mounting rod 210, a bearing 220, and the aforementioned first guide wheel 230. The first guide wheel 230 supports and guides the carbon fiber tow 500. The bearing 220 is disposed between the first guide wheel 230 and the mounting rod 210, allowing the first guide wheel 230 to rotate on the mounting rod 210. During the movement of the carbon fiber tow 500, the bearing drives the first guide wheel 230 to rotate together, thereby reducing the friction between the first guide wheel 230 and the carbon fiber tow 500.

[0043] The carbon fiber winding device also includes a frame 100. The mounting rod 210 includes a first section 211 and a second section 212. The first section 211 is connected to a bearing 220, which is located between the first section 211 and the first guide wheel 230. During the movement of the carbon fiber bundle 500, the first guide wheel 230 rotates circumferentially. The second section 212 of the mounting rod 210 is connected to the frame 100, serving to connect the first guide wheel assembly 200 to the frame 100.

[0044] Furthermore, the inner ring of bearing 220 is provided with a cavity, and the first segment 211 is located within the cavity, with a gap 240 between the first segment 211 and the surface of the cavity perpendicular to the axis of bearing 220, so that bearing 220 can rotate relative to the first segment 211 about a direction perpendicular to the axis of bearing 220. It is easy to understand that bearing 220 includes an inner ring and an outer ring, with the outer ring fixedly connected to the first guide wheel 230. When bearing 220 can rotate relative to the first segment 211 about a direction perpendicular to the axis of bearing 220, the first guide wheel 230 can also rotate relative to the first segment 211 about an axis perpendicular to the axis of bearing 220.

[0045] That is, in the above embodiment, the first guide wheel 230 can rotate in two directions. Its rotation around the axis of the bearing 220 is called circumferential rotation, and its rotation relative to the first segment 211 around an axis perpendicular to the bearing 220 is called deflection.

[0046] When using the carbon fiber production system provided in the above embodiment for production, during the winding process, the carbon fiber bundle 500 enters the carbon fiber winding device via the first guide wheel 230. The first guide wheel 230 rotates circumferentially under the action of the carbon fiber bundle 500. If the carbon fiber bundle 500 deviates from its original direction, the first guide wheel 230 and the bearing 220 will deflect relative to the first section 211 of the mounting rod 210 under the action of the carbon fiber bundle 500 (i.e., from...). Figure 2 The state shown deflects to Figure 3 (as shown in the figure), thereby improving the deviation of the carbon fiber bundle 500, and further improving the situation of the carbon fiber bundle 500 flipping and twisting during the winding process.

[0047] In some embodiments, the cavity has a first arcuate surface 221 and a second arcuate surface 222 disposed opposite to each other. The first segment 211 has a third arcuate surface and a fourth arcuate surface disposed opposite to each other. The third arcuate surface is disposed facing the first arcuate surface 221, and the fourth arcuate surface is disposed facing the second arcuate surface 222. The gap 240 is located between the first arcuate surface 221 and the third arcuate surface, and / or between the second arcuate surface 222 and the fourth arcuate surface. In this embodiment, the first arc surface 221, the third arc surface, the second arc surface 222, and the fourth arc surface are all arc surfaces. This allows the bearing 220 to rotate relative to the first segment 211 about a direction perpendicular to the axis of the bearing 220. The gap 240 is located between the first arc surface 221 and the third arc surface, or between the second arc surface 222 and the fourth arc surface. Therefore, the first segment 211 and the inner ring of the bearing 220 are in contact through the first arc surface 221 and the third arc surface, with a gap 240 between the second arc surface 222 and the fourth arc surface; or the first segment 211 and the inner ring of the bearing 220 are in contact through the second arc surface 222 and the fourth arc surface, with a gap 240 between the first arc surface 221 and the third arc surface. Because the first segment 211 and the bearing 220 are in arc surface contact, it is relatively easy to achieve deflection of the inner ring of the bearing 220 and the first guide wheel 230 relative to the first segment 211, thereby improving the deviation of the carbon fiber tow 500.

[0048] In some embodiments, the cavity further has a first plane, the first segment 211 has a second plane, and the second plane is oriented toward the first plane to restrict the inner ring of the bearing 220 from rotating about the axis of the bearing 220 relative to the first segment 211; for example, the first plane is a plane parallel to the axis of the bearing 220. By setting the first plane and the second plane, the rotation of the inner ring of the bearing 220 about the axis of the bearing 220 relative to the first segment 211 can be restricted. That is, the inner ring of the bearing 220 does not rotate circumferentially relative to the first segment 211 of the mounting rod 210, and the first guide wheel 230 rotates circumferentially with the outer ring of the bearing 220 relative to the mounting rod 210 or the inner ring of the bearing 220, so that the bearing 220 can reduce the resistance that the first guide wheel 230 needs to overcome during circumferential rotation.

[0049] Furthermore, in some embodiments, the cavity further includes a third plane parallel to the first plane. The first plane, the first arc surface 221, the third plane, and the second arc surface 222 are connected end to end to form a first segment 211 cavity for accommodating the mounting rod 210. The first segment 211 of the mounting rod 210 also includes a fourth plane parallel to the second plane. The first plane, the third arc surface, the fourth plane, and the fourth arc surface form the side surface of the first segment 211.

[0050] In some embodiments, the first arc surface 221, the second arc surface 222, the third arc surface, and the fourth arc surface are all cylindrical surfaces, and their axes are all perpendicular to the rotation axis of the bearing 220. In other embodiments, the first arc surface 221, the second arc surface 222, the third arc surface, and the fourth arc surface may also be curved surfaces with a parabolic or other curved cross-sectional shape.

[0051] In some embodiments, the second segment 212 is further provided with a bearing retainer ring, and the bearing 220 can contact the bearing retainer ring during relative rotation in a direction perpendicular to its own axis or during movement along its own axis. That is, during the deflection of the first guide wheel 230 and the bearing 220 together, the bearing 220 can contact the bearing retainer ring. Therefore, the bearing retainer ring can limit the deflection angle of the first guide wheel 230 and the bearing 220, preventing the deflection angle of the first guide wheel 230 from being too large; and the bearing retainer ring can also limit the axial displacement of the bearing 220, thereby preventing the bearing 220 and the first guide wheel 230 from undergoing large displacement together, which would cause the carbon fiber bundle 500 to deviate relative to the first guide wheel 230.

[0052] In some embodiments, the frame 100 is further provided with a mounting bracket 300 for mounting the first guide wheel assembly 200. The mounting bracket 300 includes a base plate 310, and a second segment 212 of the mounting rod 210 is threaded. One end of the second segment 212 is located on one side of the base plate 310 and threaded with a nut, while the other end of the second segment 212 is located on the other side of the base plate 310 and threaded with a nut. It is easy to understand that in this embodiment, the two nuts threaded on the second segment 212 can clamp the base plate 310, thereby fixing the mounting rod 210 to the base plate 310, so that the first guide wheel assembly 200 is mounted on the base plate 310. Furthermore, since the second segment 212 of the mounting rod 210 is threaded to connect with the two nuts, the position of the two nuts on the second segment 212 can be changed, thereby changing the distance between the first segment 211 of the mounting rod 210 and the base plate 310, and thus changing the mounting position of the first guide wheel assembly 200.

[0053] In some embodiments, the carbon fiber winding device includes multiple first guide roller assemblies 200 to simultaneously feed multiple carbon fiber bundles 500 into the carbon fiber winding device for winding, and the multiple guide roller assemblies are all connected to the base plate 310.

[0054] Furthermore, such as Figure 4As shown, the mounting frame 300 also includes a support plate 340 connected to the frame 100. A base 330 is connected to the support plate 340, and a main rod 320 is connected between the base 330 and the base plate 310. The first end of the main rod 320 is fixedly connected to the base plate 310, and the second end is rotatable relative to the base 330. It is easy to understand that as the main rod 320 rotates relative to the base 330, the base plate 310 also rotates, thereby changing the angle between the arrangement direction of the multiple first guide roller assemblies 200 on the base plate 310 and the horizontal direction. The base 330 can also be optionally fixedly connected to the second end of the main rod 320 to fix the main rod 320 when it rotates to a suitable position.

[0055] In some embodiments, the base 330 may include an upper seat and a lower seat, each of which has a notch. After the upper seat and the lower seat are connected to form the base 330, the notches of the upper seat and the lower seat are joined to form a hole-like structure. This hole-like structure is used to accommodate the second end of the main rod 320, and the hole-like structure and the main rod 320 are interference fit so that the connection between the upper seat and the lower seat can clamp the main rod 320, thereby restricting the rotation of the main rod 320.

[0056] In some embodiments of this application, such as Figure 5 As shown, the carbon fiber winding device also includes a second guide wheel 410 and a third guide wheel 420, which are located between the first guide wheel 230 and the winding shaft. The carbon fiber bundle 500 passes through the first guide wheel 230, the second guide wheel 410, and the third guide wheel 420 in sequence before being wound onto the winding shaft. In this embodiment, since the first guide wheel 230, the second guide wheel 410, and the third guide wheel 420 are all part of the carbon fiber winding device and are relatively close to each other, the carbon fiber bundle 500 entering through the first guide wheel 230 is less likely to deviate when passing through the second guide wheel 410 and the third guide wheel 420. Therefore, the installation method of the second guide wheel 410 and the third guide wheel 420 can be the existing installation method, or it can be installed on the base plate 310 using the bearing 220 structure and mounting rod 210 structure provided in this application.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
