[0024] Please refer to Figure 1 , Figure 2 , Figure 3, the edge cutting mechanism 5 includes a slider 51. The lower end of the hanging plate 4 is slidably connected with the slider 51. The upper end of the slider 51 is of a dovetail block structure. A bidirectional screw 52 is connected to the inside of the slider 51 through threads. A chute 53 is provided inside the frame 2, and the chute 53 is movably connected with the bidirectional screw 52. By providing the chute 53, the bidirectional screw 52 can move up and down. A knob 54 is fixedly connected to the outer side of the middle part of the bidirectional screw 52. A limiting plate 55 is fixedly connected to the lower end of the hanging plate 4, and the limiting plate 55 is slidably connected with the knob 54. By providing the limiting plate 55, the knob 54 is limited. A cutting machine 56 is fixedly connected to the lower end of the slider 51. By rotating the bidirectional screw 52, the slider 51 makes a threaded movement, so that the distance between the two sliders 51 is convenient to adjust, and then the distance between the two cutting machines 56 changes, so that when the device is in use, the edge of the para-aramid cloth with different widths can be trimmed.

[0025] Please refer to Figure 1 , Figure 2 , Figure 4 , a guide cylinder 57 is fixedly connected to the lower end of the slider 51. A guide rod 58 is slidably connected to the inside of the guide cylinder 57. A spring 59 is arranged inside the guide cylinder 57.

[0026] The specific implementation process of the utility model is as follows: when in use, the pressing plate 510 is manually moved up, so that the pressing plate 510 drives the guide rod 58 to slide in the guide cylinder 57, so that the spring 59 is compressed, and then the cloth 9 passes between the pressing plate 510 and the supporting plate 512, and one end of the cloth 9 is wound around the winding roller 7, and the pressing plate 510 is released. The spring 59 resets the guide rod 58, so that the pressing plate 510 elastically presses the cloth 9 on the supporting plate 512, and then the motor 8 is started. The motor 8 starts to drive the winding roller 7 to rotate to wind the cloth 9, and the driving device of the cutting machine 56 is started to drive the cutting machine 56 to work, and then according to the cloth 9 width adjustment device, the bidirectional screw 52 and the slider 51 are manually rotated to make a threaded motion, and the cloth 9 is adjusted. This makes it easy to adjust the distance between the two sliders 51, and further changes the distance between the two cutters 56, so that when the device is in use, it can cut the edges of the para-aramid cloths of different widths. The cylinder 3 is started, and the cylinder 3 drives the cylinder rod to extend, so that the hanging plate 4 moves down, and then the slider 51 moves down, so that the cutting wheel of the cutter 56 moves down and enters the knife groove 511 to cut the edges of the cloth 9. At the same time, the guide cylinder 57 moves down so that the spring 59 acts on the guide rod 58, so that the pressing plate 510 elastically presses the cloth 9 on the supporting plate 512, so that the cloth 9 is limited during the cutting process to prevent wrinkles. At the same time, the cloth 9 is tightened during the winding process of the winding roller 7 to prevent the cloth 9 from being loosened during winding.
