The distance between the two limiting plates 24 can be adjusted, which is suitable for cardboard of different specifications.
[0046] Example 3
[0047] Die-cutting component 3 includes:
[0048] Support frame 2 31 is fixedly connected to the top of the operating table 1 near the right side of the conveyor belt 231. A hydraulic rod 311 is fixedly connected to the top of support frame 2 31.
[0049] Connecting block 312 is fixedly connected to the bottom output end of hydraulic rod 311;

When the die-cutting plate 32 comes into contact with the cardboard, the sponge pad 322 provides cushioning to prevent the blade 321 from being damaged due to excessive impact force.
[0054] A specific application of this embodiment is as follows: In use, firstly, adjust the spacing of the baffles 21 according to the cardboard specifications, push the connecting rod 212 to slide inside the support block 211, then rotate the threaded knob 213 to make the outer surface of the bottom connecting rod 212 contact and fix the baffle 21. Then, similarly, use the connecting rod 242 and the threaded knob 243 to adjust and lock the spacing of the two limiting plates 24, stack the cardboard between the four baffles 21, start the motor 222, and drive the two conveyor wheels 221 to rotate through the coupling, conveying the cardboard through the gap at the bottom of the right baffle 21 to the surface of the conveyor belt 231. Start the motor 232 to drive the drive shaft in the conveyor belt 231 to rotate, thereby causing the conveyor belt 231 to move the cardboard to the die-cutting assembly 3. During the movement of the cardboard... Two limiting plates 24 limit the cardboard to keep it in the center position. The roller 252 is pressed against the cardboard surface by the elastic force of the spring 253 to prevent the cardboard from moving axially. The die-cutting plate 32 is fixed to the bottom of the connecting block 312 by bolts, which facilitates the replacement of the die-cutting plate 32. When the cardboard is conveyed to the bottom of the die-cutting plate 32, the hydraulic rod 311 is activated to push the connecting block 312 and the die-cutting plate 32 down. The blade 321 at the bottom of the die-cutting plate 32 cuts the cardboard to complete the die-cutting operation. At the same time as the die-cutting plate 32 descends, the limiting rod 313 slides on the top of the support frame 31 to provide a stable movement trajectory for the movement of the die-cutting plate 32 and avoid deviation or jamming. When the die-cutting plate 32 comes into contact with the cardboard, the sponge pad 322 provides cushioning to prevent the blade 321 from being damaged by excessive impact.
