Description

Technical Field

[0001] This invention relates to the field of carbon fiber processing technology, and more specifically, to a carbon fiber cutting device. Background Technology

[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of over 95%. Due to its high strength and lightweight properties, it has wide applications in new energy, automotive, aerospace, high-end equipment manufacturing, and medical devices. During carbon fiber processing, pre-oxidized carbon fibers undergo low-temperature and high-temperature carbonization to transform into disordered-layer graphite structure fibers. As the carbonization process proceeds, non-carbon atoms are gradually removed at high temperatures, resulting in the generation of a large amount of waste gas. To effectively discharge this waste gas from the exhaust port and reduce its impact on carbon fiber quality, it is necessary to determine the weight loss zone within the carbonization furnace using the carbon fiber thermogravimetric curve. Therefore, carbon fiber samples of the designed dimensions need to be cut and tested to calculate the carbon fiber thermogravimetric curve.

[0003] Currently, carbon fiber test samples are typically measured and cut to a predetermined length manually, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0023] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of over 95%. Due to its high strength and lightweight properties, it has wide applications in new energy, automotive, aerospace, high-end equipment manufacturing, and medical devices. During carbon fiber processing, after pre-oxidation, the carbon fiber undergoes low-temperature and high-temperature carbonization to transform into disordered-layer graphite structure fibers. As the carbonization process proceeds, non-carbon atoms are gradually removed at high temperatures, accompanied by the generation of a large amount of waste gas. To effectively discharge this waste gas from the exhaust port and reduce its impact on carbon fiber quality, it is necessary to determine the weight loss zone within the carbonization furnace using the carbon fiber thermogravimetric curve.

[0024] Currently, carbon fiber test samples are typically measured and cut to a predetermined length manually using scissors and a ruler. This measurement and cutting process is time-consuming, labor-intensive, and inefficient.

[0025] The following detailed description of the overall structure, working principle, and technical effects of the carbon fiber cutting device provided by the present invention, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0026] Please refer to Figures 1-3 This invention provides a carbon fiber cutting device, applied to the carbon fiber production process, specifically used to cut carbon fiber samples of designed dimensions to facilitate testing and obtain the carbon fiber thermogravimetric curve, thereby determining the weight loss zone of the carbon fiber in the carbonization furnace.

[0027] Please refer to Figure 1 and Figure 2 The carbon fiber cutting device provided by this invention includes a base 100, guide rods 200, and cutting components 300. The base 100 has a horizontal surface, and the surface of the base 100 has a first direction a and a second direction b that are perpendicular to each other. Several guide rods 200 are provided at both ends of the base 100, and the guide rods 200 are located at both ends of the base 100 surface along the first direction a. The guide rods 200 at both ends of the base 100 are spaced apart along the second direction b. Carbon fibers are alternately wound around the several guide rods 200 along the first direction a. The cutting components 300 are provided on the base 100, and several cutting components 300 are spaced apart along the first direction a. The several cutting components 300 can simultaneously cut the carbon fibers wound between the several guide rods 200 along the second direction b.

[0028] Understandably, when carbon fibers are alternately wound between several guide rods 200, a portion of the carbon fibers are connected along the first direction a to the guide rods 200 at opposite ends of the base 100, and a portion of the carbon fibers are connected along the second direction b to the guide rods 200 at the same end of the base 100. This makes the overall shape of the carbon fibers wound on the base 100 similar to the waveform of a square wave. Furthermore, when the carbon fibers are cut by the cutting assembly 300, multiple points are cut simultaneously to cut them into segments of the same size.

[0029] Carbon fibers are alternately wound between several guide rods 200, and then cut simultaneously along the second direction b by several cutting components 300, thereby cutting the carbon fibers into several carbon fiber sample segments of fixed length. This eliminates the need for operators to manually measure and cut, saving time and effort, improving production efficiency, ensuring uniform length of carbon fiber samples, improving the accuracy of subsequent tests, and ultimately improving the quality of carbon fiber products.

[0030] Please refer to Figure 1 and Figure 2 In some alternative embodiments, the cutting assembly 300 includes a connector 310 and a cutter 320. The connector 310 is disposed on the side of the base 100, and multiple connectors 310 are spaced apart along the second direction b. Each connector 310 is rotatably mounted with a cutter 320, the end of which extends along the second direction b. It is understood that the length of the cutter 320 needs to be greater than the coverage area of ​​the guide rod 200. The cutter 320 can be driven to rotate to approach or move away from the surface of the base 100, thereby cutting the carbon fiber bundles located on the surface of the base 100.

[0031] Please refer to Figure 1 and Figure 2In some optional embodiments, a slide rail 110 is provided on the side of the base 100 along the first direction a, and the connector 310 is adapted to the slide rail 110 and slidably disposed within the slide rail 110. The specific cross-sectional shape of the connector 310 and the slide rail 110 is not limited in this embodiment, as long as the connector 310 is adapted to the slide rail 110 and can move along the slide rail 110. By driving the connector 310 to move along the slide rail 110 to the designed position, the position and spacing of several cutting components 300 can be adjusted to cut carbon fiber bundles of different lengths, suitable for test samples with different requirements, thus improving the applicability and compatibility of the carbon fiber cutting device. Furthermore, the carbon fiber cutting device also includes a fixing member 330, which is disposed on the connector 310 and used to fix the connector 310 to the slide rail 110. The fastener 330 can be a pin, bolt, buckle, or other structure used to abut and fix the connector 310 to the base 100. The specific structural form of the fastener 330 is not limited in this embodiment.

[0032] Please refer to Figure 1 and Figure 2 Furthermore, to facilitate the adjustment of the spacing between the cutting components 300 and the guide rods 200, and to precisely control the cutting length of the carbon fiber, in some optional embodiments, a first scale line 120 is provided on the surface of the base 100 along a first direction a, and a second scale line 130 is provided on the surface of the base 100 along a second direction b. By providing the first scale line 120 on the base 100 along the first direction a, the length of the carbon fiber bundle in the first direction a can be displayed intuitively. When moving the cutting components 300 along the first direction a, the moving distance of the cutting components 300 and the spacing between adjacent cutting components 300 can be precisely controlled. Therefore, when cutting carbon fiber samples, there is no need to use external measuring tools such as rulers; simply controlling the spacing of the cutting components 300 is sufficient to accurately cut carbon fiber samples that meet the design requirements.

[0033] In some optional embodiments, a V-shaped groove is formed on the surface of the base 100, extending along the second direction b. The V-shaped groove is used to accommodate the cutting scissors 320, allowing the cutting scissors 320 to cut into the carbon fiber during cutting, so that the cutting scissors 320 can completely cut the carbon fiber. Furthermore, the V-shaped groove coincides with the second scale line 130, that is, several equally spaced V-shaped grooves on the surface of the base 100 simultaneously serve as multiple second scale lines 130, thereby facilitating the cutting scissors 320 to cut along the points on the second scale line 130, and thus facilitating the cutting of carbon fiber samples that meet the length requirements.

[0034] Please refer to Figure 1 and Figure 2In some optional embodiments, the carbon fiber cutting device also includes a connecting rod 400, with a through hole 321 at the end of the cutter 320 away from the connector 310. The connecting rod 400 is adapted to the size of the through hole 321, so that the connecting rod 400 can pass through the through hole 321 simultaneously through several cutters 320, connecting several cutters 320 into a whole, thereby driving several cutters 320 to move synchronously, achieving the effect of cutting multiple points of carbon fiber at the same time, and improving cutting efficiency.

[0035] Further, please refer to Figure 1 and Figure 3 The spacing between adjacent guide rods 200 at both ends of the base 100 is adjustable. By adjusting the distance between adjacent guide rods 200, the distance at which the carbon fiber is wound along the second direction b between adjacent guide rods 200 is adjusted. This, combined with the adjustment of the spacing of several cutting components 300, ensures that the length of the carbon fiber at both ends of the base 100 is equal to the designed cutting length. Figure 3 L is the designed cutting length, d is the distance between adjacent guide rods 200, and c is the distance between the cutting component 300 located at the edge of the base 100 and the edge of the base 100. By adjusting the distance between the guide rods 200 and adjusting the position of the cutting component 300, L = d + 2c is made so that the length of the carbon fiber located at the edge of the base 100 is equal to the designed cutting length, thus avoiding waste of carbon fiber.

[0036] In summary, the carbon fiber cutting device provided by this invention operates on the following principle: carbon fibers are alternately wound between several guide rods 200, and several cutting components 300 simultaneously cut the carbon fibers along the second direction b, thereby cutting the carbon fibers into several carbon fiber sample segments of fixed length. This eliminates the need for manual measurement and cutting by operators, saving time and effort, improving production efficiency, ensuring uniform length of carbon fiber samples, improving the accuracy of subsequent tests, and ultimately improving the quality of carbon fiber products.
