A crank 17 is rotatably connected between the slide 10 and the corresponding flywheel 16. A discharge tray 18 is fixedly installed on one side of the top of the second frame 3;

[0027] like Figure 2-Figure 6As shown, the fixing seat 12 is a U-shaped structure, with a top block 19 inserted and installed on the top of the fixing seat 12, and a fixing bolt 20 is threadedly connected between the top block 19 and the fixing seat 12, and an axle seat 21 is movably installed in the fixing seat 12, and a transverse axle hole 22 is opened in the center position of the axle seat 21. The axle seat 21 is inserted and installed in the fixing seat 12, and the fixing bolt 20 also passes through the through hole on one side of the axle seat 21, and the fixing bolt 20 located between the axle seat 21 and the top block 19 is provided with a first compression spring 23. Based on this, through the arrangement of the axle seat 21 and the fixing bolt 20, installation conditions can be provided for the pressure roller 13, and a force can be applied to the pressure roller 13 in the direction of the support platform 2. One end of the second rotating shaft 24 passes through the corresponding axle seat 21 and is fixedly installed with an end block 25. A slot 27 is opened at one end of the gear 26. The gear 26 is inserted and installed on the end block 25 through the slot 27 and fixed by screws.

[0028] It should be noted that the present invention is a length-adjustable CNC fiber cutting machine. When cutting a fiber bundle, the fiber bundle is first placed on the supporting platform 2, and one end of the fiber bundle is placed on the bottom side of the pressure roller 13. Then, the motor 7 is started, and the motor 7 drives the second synchronous wheel 8 to rotate, and the second synchronous wheel 8 rotates the first synchronous wheel 6 synchronously through the synchronous belt. As a result, the first synchronous wheel 6 drives the first rotating shaft 5 to rotate in the third frame 4 and drives the flywheels 16 at both ends to rotate, so that the two flywheels 16 can respectively drive the slide 10 to reciprocate vertically on the guide column 9 through the crank 17, and then the two slides 10 drive the cutter 11 to reciprocate up and down. Synchronously, the slide 10 drives the side plate 14 to move up and down, that is, the side plate 14 The downward movement causes the side plate 14 to drive the tooth plate 15 to move downward synchronously, so that the tooth plate 15 drives the multiple active tooth blocks 31 on one side to move downward synchronously, and uses the inclined surface on one side of the bottom of the active tooth block 31 to be limited by the gear 26 and move toward the side plate 14 to compress the second compression spring 32, so that when the cutter 11 cuts the fiber bundle, the pressure roller 13 is not transmitted, and when the slide 10 drives the cutter 11 to move upward, it drives the tooth plate 15 upward synchronously through the side plate 14, so that the tooth plate 15 can be meshed with the gear 26 through the multiple active tooth blocks 31 on one side, and then the gear 26 drives the second rotating shaft 24 and the pressure roller 13 to rotate a certain angle, so that the fiber bundle continues to be transported to a certain length below the cutter 11, and the automatic transportation and cutting process can be completed.

[0029] When it is necessary to adjust the single conveying length of the fiber bundle, the installation position of the tooth plate 15 can be adjusted through the two sliders 33, and then by adjusting the number of active tooth blocks 31 meshing with the gear 26, the rotation amplitude of the gear 26 can be adjusted, and then the single rotation amplitude of the shaft seat 21 and the pressure roller 13 can be adjusted, thereby adjusting the single conveying length of the fiber bundle by the pressure roller 13.
