A fixing rod 18 is installed in the inner cavity of the movable groove 16. A spring 19 is wound around the outer wall of the fixing rod 18 and is movably connected to the movable groove 16. Inside the cavity, handles 17 are symmetrically installed at both ends of the spring 19. The handles 17 are movably connected to the inner cavity of the movable groove 16. The handles 17 are connected to the adjusting block 15. The other end of the adjusting block 15 is movably connected to the inner cavity of the movable groove 16. The adjusting block 15 and the handles 17 are both sleeved on the outer wall of the fixed rod 18. The first mounting grooves 3 are symmetrically opened on both sides of the inner cavity of the connecting block 2. The size of the first mounting grooves 3 and the adjusting block 15 are matched. The adjusting block 15 fits against the inner wall of the positioning groove 4. The first mounting groove 3 is opened on the outer wall of the connecting block 2. By setting the connecting block 2, when installing the second pulling shaft 21 and the first pulling shaft 20, the connecting block 2 can be inserted into the table. With the adjustable height adjustment component 1, the distance between the first pulling shaft 20 and the second pulling shaft 21 and the table can be adjusted. In actual use, it can be freely adjusted according to the work requirements, so that the first pulling shaft 20 and the second pulling shaft 21 can better perform the material pulling work. The spring 19 can constantly push the adjusting blocks 15 at both ends outward, so that the adjusting blocks 15 can fit tightly in the inner cavity of the positioning groove 4, which can complete the initial positioning of the adjusting component 1. When the connecting block 2 needs to be installed, the adjusting component 1 can fit against the bottom of the table and connect it to the table through the second mounting groove 13. At the same time, the connecting block 2 can also be directly installed on the top of the table through the adjusting component 1 and the second mounting groove 13, which can increase the pulling height of the first pulling shaft 20 and the second pulling shaft 21.

[0019] Example 2: like Figure 1 , Figure 2 , Figure 4 As shown, a material pulling shaft mechanism for a cutting machine includes two connecting blocks 2 rotatably connected to opposite sides of a first material pulling shaft 20. A drive assembly 5 is mounted on the outer wall of one connecting block 2. A fine-tuning assembly 9 is mounted on the top of the connecting block 2. A second material pulling shaft 21 is movably connected to the side of the fine-tuning assembly 9. A lead screw 11 is rotatably connected to one side of the inner cavity of the fine-tuning assembly 9. A rotating handle 10 is rotatably connected to the top of the fine-tuning assembly 9 and is connected to the lead screw 11. A movable block 12 is movably connected to the inner cavity of the fine-tuning assembly 9. One end of the movable block 12 is threadedly connected to the lead screw 11. The second material pulling shaft 21 is rotatably connected to the movable block 12. A servo motor 6 is mounted on the outer wall of the drive assembly 5. A synchronous belt 7 is mounted in the inner cavity of the drive assembly 5. Synchronous pulleys 8 are mounted at both ends of the inner cavity of the synchronous belt 7. The servo motor 6 is connected to the bottom synchronous pulley 8 through a first rotating shaft. The bottom synchronous pulley 8 is connected to the first material pulling shaft 20. The top synchronous pulley 8 is connected to the second material pulling shaft 21 through the movable block 12. The servo motor 6 can drive the first pulling shaft 20 and the second pulling shaft 21 simultaneously via the synchronous belt 7 and the synchronous pulley 8. The first pulling shaft 20 and the second pulling shaft 21 are detachable and can be easily replaced. By rotating the handle 10, the lead screw 11 can be rotated, so that the movable block 12 can be threadedly connected to it. Based on this, the distance between the second pulling shaft 21 and the first pulling shaft 20 can be adjusted, so it can be adapted to pull materials of various thicknesses.

[0020] It should be noted that this utility model is a material pulling shaft mechanism for a cutting machine. During use, the height of the first material pulling shaft 20 and the second material pulling shaft 21 is selected according to the installation requirements. When the first material pulling shaft 20 and the second material pulling shaft 21 need to be close to the table surface, the table surface is opened with a slot so that the bottom of the connecting block 2 can be inserted into the slot. Press the handle 17 to drive the adjusting block 15 to retract into the inner cavity of the movable groove 16. Insert the connecting seats 14 on both sides of the adjusting component 1 into the inner cavity of the bottom of the connecting block 2. Release the handle 17 so that the adjusting block 15 can fit in the inner cavity of the positioning groove 4. Move the connecting block 2 according to the required height of the first material pulling shaft 20 and the second material pulling shaft 21. After the movement is completed, lift the adjusting component 1 upward and connect it to the table surface with the second mounting groove 13 and the matching bolts. When it is necessary to directly install the first pull shaft 20 and the second pull shaft 21, simply place the adjustment component 1 on the table for installation. Rotate the handle 10 to drive the lead screw 11 to rotate, so that the movable block 12 can drive the second pulling shaft 21 to move. Based on this, the gap between the first pulling shaft 20 and the second pulling shaft 21 is adjusted. After the adjustment is completed, install the timing belt 7 and timing wheel 8 of appropriate size. After starting the servo motor 6, the first pulling shaft 20 and the second pulling shaft 21 can be driven to pull materials.
