A cutting mechanism 5 is provided above the processing table 1 near the limiting component 4. The cutting mechanism 5 includes a cutting frame 501 provided above the processing table 1 near the limiting frame 401. The inner wall of the cutting frame 501 is provided with multiple electric telescopic rods 502. There are two electric telescopic rods 502. One end of the electric telescopic rod 502 is provided with a cutting mounting seat 503. A cutting knife 504 is installed below the cutting mounting seat 503. Multiple mounting screws 505 are threadedly connected to the cutting knife 504 and the cutting mounting seat 503. There are three mounting screws 505. A cutting seat 506 is in contact below the cutting knife 504. The cutting seat 506 is fixedly connected to the processing table 1. Electric telescopic pole 2 502, electric telescopic pole 1 402, conveyor 305, and servo motor 202 are electrically connected to a controller during actual use, and electric telescopic pole 2 502, electric telescopic pole 1 402, conveyor 305, and servo motor 202 are electrically connected to an external power supply. The cutting seat 506 has multiple chip discharge ports 6, and there are three chip discharge ports 6, which are used to drop chips. A collection rack 7 is installed below the processing table 1, and a collection box 8 is installed on the collection rack 7, which is used to collect the chips generated when the rubber airbag curtain is cut. The collection box 8 is opposite to the chip discharge ports 6 and the conveyor 305. Multiple auxiliary plates 9 are fixed on both sides of the cutting mounting base 503. There are two auxiliary plates 9 in total, and four in total. A spring-loaded telescopic rod 10 is provided below the auxiliary plates 9 and the placement frame 201. There are four spring-loaded telescopic rods 10 on the auxiliary plates 9 and two spring-loaded telescopic rods 10 on the placement frame 201. A pressing plate 11 is provided at one end of the spring-loaded telescopic rod 10. One of the pressing plates 11 has an arc-shaped structure for better fitting of the curtain fabric. The spring-loaded telescopic rod 2 10 and the spring-loaded telescopic rod 1 302 consist of telescopic rod 1, telescopic rod 2 and their springs. One end of telescopic rod 1 is nested and connected to the inner wall of telescopic rod 2 through a sealing block or sealing gasket. The spring is fitted on the outside of telescopic rod 1 and telescopic rod 2.

[0023] The working principle of the overall technical solution formed by the above embodiments is as follows: During processing, the worker places the curtain fabric (the roller with the curtain fabric wound around it) into the placement cylinder 204. At the same time, the spring-loaded telescopic rod 10 set in the placement frame 201 drives the pressing plate 11 to press the placed curtain fabric. Then, the servo motor 202 is started, which drives the placement cylinder 204 to release the wound curtain fabric and the rotating rod 203 to rotate. At the same time, the spring-loaded telescopic rod 302 set in the mounting frame 301 pushes the pressing frame 303, so that the pressing roller 304 presses tightly against the surface of the curtain fabric. The elasticity of the spring adaptively adjusts the pressure to ensure that the fabric surface is flat and without deviation during the conveying process. Then, the conveyor belt of the curtain fabric conveyor 305 conveys it forward. After being conveyed by the conveyor 305, the electric telescopic rods 402 on both sides of the limiting frame 401 extend synchronously, pushing the limiting plate 403 to clamp the edges of the curtain fabric on both sides to prevent lateral displacement. At the same time, the electric telescopic rod 402 above the limiting frame 401 pushes the limiting frame 404 down. The limiting roller 405 connected by bearing 3 inside the limiting frame 404 rolls in contact with the surface of the curtain fabric, which can both limit longitudinal sliding and maintain uniform tension through rolling friction. After the curtain fabric is conveyed to the preset length by the conveyor 305, the conveyor 305 stops, and the system enters the cutting preparation stage. Then, the electric telescopic rod 502 set on the cutting frame 501 is activated, pushing the cutting mounting seat 503 to move vertically downward, causing the cutting blade 504 to contact the cutting seat 506. The auxiliary plates 9 on both sides of the cutting mounting seat 503 are linked with the spring-loaded telescopic rod 10, and the pressing plate 11 presses the two sides of the curtain fabric at the moment of cutting to prevent the fabric from rebounding or sliding, ensuring a straight cut. The cutting blade 504 completes the cutting under the strong pressure of the electric telescopic rod 502. The hard surface of the cutting seat 506 provides supporting reaction force to ensure cutting efficiency. After cutting, the electric telescopic rod 502 resets, the cutting blade 504 rises, and the pressing plate 11 rebounds synchronously with the spring-loaded telescopic rod 10 to release the pressure. The conveyor 305 restarts after cutting, and the curtain cloth automatically slides out through the guide groove and inclined guide plate 12 on the side of the processing table 1 to enter the next process. The chip discharge port 6 on the cutting seat 506 automatically aligns with the collection box 8 below the processing table 1 to ensure that the chips generated by subsequent cutting fall directly into the collection box 8 through the chip discharge port 6, avoiding chip accumulation that interferes with cutting accuracy. Then, the placement mechanism 2 continuously releases the curtain cloth, and the above process is repeated to achieve continuous operation.
