The processing quality of aerospace fabrics directly affects the overall performance, reliability, and service life of spacecraft; therefore, efficient and precise aerospace fabric processing technology has become a research hotspot in the aerospace manufacturing field.

[0003] To meet diverse application requirements, aerospace fabrics often need to be cut into circular or other shapes. For example, sealing gaskets at engine compartments and wing seams require high-strength, high-temperature-resistant aerospace fabrics with circular outlines that precisely match curved surfaces to prevent pressure leaks caused by gaps. Electromagnetic shielding fabric linings of radomes and radomes require circular cutting to achieve seamless coverage and prevent signal interference. However, existing cutting devices typically only achieve simple cutting of aerospace fabrics and cannot quickly cut them into circles. Therefore, a cutting device for aerospace fabric processing is proposed to address these issues. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-3This embodiment of a cutting device for aerospace fabric processing includes a mounting frame 1, a workbench 11 on the top of the mounting frame 1, a receiving roller 12 for conveying aerospace fabric on one side of the workbench 11, and a cutting assembly 2 for cutting aerospace fabric on the top of the workbench 11. The mounting frame 1 also has a transmission component 13 for transmission, and a transmission belt 14 is connected to the output end of the transmission component 13. The transmission belt 14 is connected to the cutting assembly 2. The workbench 11 also has a receiving port 17 for collecting the cut aerospace fabric. The receiving port 17 has a guide channel 18 for guiding the cut aerospace fabric. A first support roller 15 for supporting the aerospace fabric and a guide wheel 16 for guiding the aerospace fabric are also provided between the cutting assembly 2 and the receiving roller 12. In practical use, when it is necessary to cut the aviation fabric, the operator first places the fabric to be cut on the receiving roller 12 and passes it through the first support roller 15 so that the first support roller 15 supports the aviation fabric and the two sides of the aviation fabric are located in the grooves on the guide wheel 16, so as to achieve the guiding effect of the aviation fabric. Then it is connected to the cutting component 2. At this time, the operator can control the transmission belt 14 to start, so that the transmission component 13 drives the transmission belt 14 to achieve the effect of power output to the cutting component 2, thereby achieving the cutting effect of the aviation fabric. The cut aviation fabric will fall into the receiving port 17 under the action of gravity, and finally be discharged through the guide channel 18, thus achieving the effect of collecting the cut aviation fabric and ensuring the stability of the device during use.

[0025] It is worth noting that the preferred transmission component is a combination of a drive motor and a reducer, with a corresponding drive wheel at its output end.

[0026] The technical effects of the above embodiments are as follows: by setting the cutting component 2, it can effectively achieve a good cutting effect on the aviation fabric during use, thereby meeting different usage requirements and increasing the applicability of the device during use. By setting the first support roller 15 and guide wheel 16, the stability during the conveying of the aviation fabric is ensured, the accuracy of the cutting component 2 in the cutting process of the aviation fabric is increased, and the situation of poor cutting effect caused by wrinkles is avoided.

[0027] As a preferred technical solution in this embodiment:

[0028] The cutting assembly 2 includes a first support frame 201 for mounting the cutting component and a second support frame 202 for mounting the winding component. The first support frame 201 is provided with a drive shaft 204 for cutting the aviation fabric. The drive shaft 204 is provided with a plurality of cutting blades 205 for cutting the aviation fabric. The first support frame 201 is also provided with a second support roller 206 for supporting the aviation fabric. The second support roller 206 is installed directly below the drive shaft 204. Both ends of the connector 203 are provided with connecting blocks 2031 connected to the driven wheel 210. The connector 203 is rotatably connected to the connecting blocks 2031 through a mounting shaft. Both ends of its shaft extend to the outside of the connecting blocks 2031 and are provided with linkage wheels 207 for linkage. One of the linkage wheels 207 is kept taut and connected to the transmission belt 14. In actual use, the operator can place the aviation fabric to be cut between the drive shaft 204 and the second support roller 206. Then, when the operator controls the transmission component 13 to drive the transmission belt 14 to rotate, the transmission belt 14 can effectively drive the linkage wheel 207 to rotate, thereby enabling the linkage wheel 207 to drive the drive shaft 204 and the cutting blade 205 to rotate. At this time, the cutting blade 205 can effectively cut the aviation fabric during rotation, and the rotation of the drive shaft 204 can achieve faster work efficiency.

[0029] The technical effects of the above embodiments are as follows: by setting the drive shaft 204 and the cutting blade 205, the aviation fabric can be effectively cut quickly during use. This method can effectively improve work efficiency and enable more aviation fabric to be cut in the same amount of time.

[0030] As a preferred technical solution in this embodiment:

[0031] The top of the first support frame 201 is equipped with a mounting bracket 2021. Two connecting blocks 2031 are also equipped with adjusting screws 2032 for adjustment. One end of each adjusting screw 2032 passes through 2021 and is fitted with an adjusting nut 2033. In actual use, the operator can adjust the adjusting nut 2033 to rotate it, thereby causing the adjusting screw 2032 to move. This displacement of the adjusting screw 2032 causes displacement of the connecting piece 203 and the drive shaft 204, thus adjusting the distance between the drive shaft 204 and the second support roller 206. This ensures that it can adapt to aviation fabrics of different thicknesses during use.

[0032] As a preferred technical solution in this embodiment:

[0033] The second support frame 202 is equipped with a take-up roller 211 for winding up the aviation fabric, and a third support roller 212 for support is provided at the bottom of the take-up roller 211. The take-up roller 211 is mounted on the second support frame 202 via a shaft, and a driven wheel 210 is provided at one end of the shaft. A linkage belt 208 is tensioned between the driven wheel 210 and the linkage wheel 207. In actual use, the operator can connect one end of the aviation fabric to be cut to the take-up roller 211. Then, when the operator controls the transmission component 13 to drive the linkage wheel 207 to rotate, the linkage wheel 207 can drive the driven wheel 210 to rotate the take-up roller 211. This satisfies the requirement of using only one drive source to ensure the cutting and winding of the aviation fabric, further simplifying the structure of the device and reducing its operating cost.

[0034] As a preferred technical solution in this embodiment:

[0035] A tensioning wheel 209 is provided between the first support frame 201 and the second support frame 202 to support the linkage belt 208. The tensioning wheel 209 effectively ensures the tension of the linkage belt 208 during use, thus preventing the linkage belt 208 from becoming too slack or too taut when the position of the connecting piece 203 and the drive shaft 204 is adjusted. This increases the safety of the device during use.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
