The output shaft of the first servo motor 4 is connected to the first threaded rod 5, which is located between the front and rear sides of the mounting frame 3. The movable seat 6 is threadedly connected to the outer side of the first threaded rod 5. A limiting rod is provided between the mounting frames 3, passing through the movable seat 6, allowing the movable seat 6 to slide back and forth on the limiting rod. A connecting plate 7 is located at the bottom of the movable seat 6, and a groove is opened at the right end of the connecting plate 7. A connecting rod 10 is slidably connected in the groove. An eccentric pin 11 is provided at the left end of the connecting rod 10. A cutting blade 12 is provided at the bottom of the connecting rod 10. A first turntable 8 is rotatably connected to the right side of the movable seat 6. A rotary motor is provided on the left side of the movable seat 6. A rotating shaft is connected to the output shaft of the rotary motor. The rotating shaft passes through the movable seat 6 and is fixedly connected to the center point of the first turntable 8. A fixed seat 81 is fixedly connected to the right side of the first turntable 8. A second servo motor 83 is provided at the top of the fixed seat 81. A third threaded rod is connected to the output shaft of the second servo motor 83. A groove 82 is opened on the fixed seat 81. The third threaded rod is located in the groove 82. A protrusion 92 is provided in the groove 82. The protrusion 92 is threadedly connected to the third threaded rod. A second turntable 9 is provided to the right side of the protrusion 92. An arc-shaped groove 91 is opened on the right side of the second turntable 9. The arc-shaped groove 91 fits with the eccentric pin 11.

[0023] like Figure 7 As shown, it also includes a mounting block 18, a second threaded rod 19, a guide rod 20, an electric push rod 21, a fixing plate 22, and a knob. Mounting blocks 18 are provided on both the front and rear sides of the worktable 1. The mounting block 18 is provided with a second threaded rod 19 and a guide rod 20. A knob is provided on the top of the second threaded rod 19. The outer side of the second threaded rod 19 is threadedly connected to the mounting plate 24. The guide rod 20 passes through the mounting plate 24. An electric push rod 21 is provided at the bottom of the mounting plate 24. A fixing plate 22 is provided at the bottom of the telescopic rod of the electric push rod 21. The two electric push rods 21 operate synchronously.

[0024] like Figure 7 As shown, it also includes electric guide rails 16, push plates 17 and scale lines. Electric guide rails 16 are provided on both the front and rear sides of the worktable 1. Push plates 17 are provided between the moving parts of the two electric guide rails 16. Scale lines are provided on the top of the worktable 1.

[0025] like Figure 7 As shown, it also includes a fan 14. The support frame 2 has a fan 14 at the bottom, and the fan 14 can clean up debris on the surface of the workbench 1.

[0026] like Figure 7As shown, it also includes a collection box 15. The collection box 15 is slidably connected to the bottom of the workbench 1. The collection box 15 is located directly below the cutting channel of the workbench 1. The collection box 15 can collect waste and debris generated during the cutting process and keep the work area clean.

[0027] like Figure 6 and Figure 7 As shown, it also includes a ranging sensor 23 and a control panel 13. The ranging sensor 23 is located on the top of the mounting block 18, and the control panel 13 is located on the front side of the support frame 2. The ranging sensor 23, the first servo motor 4, the second servo motor 83, the rotary motor, the electric push rod 21, and the electric guide rail 16 are all electrically connected to the control panel 13.

[0028] Power is turned on, and the knob is rotated according to the stack height of the cardboard to be cut. The knob drives the second threaded rod 19 to rotate to adjust the height of the mounting plate 24. Then, according to the required cutting length, the position of the push plate 17 is adjusted by controlling the electric guide rail 16 through the control panel 13 and the scale lines. Then, the electric guide rail 16 is turned off, and the operator pushes the cardboard until it contacts the push plate 17. Then, the electric push rod 21 is activated. The telescopic rod of the electric push rod 21 drives the fixing plate 22 to move downward to fix the cardboard. After the cardboard is fixed, the distance sensor 23 feeds back the cardboard thickness to the control panel 13. The operator uses the cardboard thickness data fed back by the control panel 13 to control the rotation of the third threaded rod through the second servo motor 83, which drives the protrusion 92 to move up and down to change the rotational eccentricity of the second turntable 9. The second servo motor 83 is turned off, and the first servo motor 4 and the rotary motor are started. The first servo motor 4 drives the first threaded rod 5 to rotate, thereby driving the cutting blade 12 to move horizontally via the moving seat 6. The rotary motor drives the first turntable 8 to rotate, and the first turntable 8 drives the second turntable 9 to rotate. As the second turntable 9 rotates, the position of the eccentric pin 11 changes continuously within the arc groove 91, causing one end of the connecting rod 10 to move along a circular trajectory, while the other end of the connecting rod 10 is restricted in the slide groove. Therefore, the connecting rod 10 will move up and down reciprocatingly following the movement of the eccentric pin 11, thereby driving the cutting blade 12 to move up and down reciprocally. After completing one cut, the control panel 13 controls the cutting blade 12 to return to its original position via the first servo motor 4, then controls the extension rod of the electric push rod 21 to lift to release the cardboard from its fixation, and then controls the push plate 17 to move by one cutting length via the electric guide rail 16. The above steps are repeated to complete multiple cuts.
