[0025] A guiding device 2, the guiding device 2 is fixedly arranged on the upper end surface of the support card board 4, and two groups of die-cutting devices 3 for die-cutting are threadedly connected to the inner end surface of the guiding device 2.

[0026] The guiding device 2 includes a die-cutting cylinder 27, the output end of the die-cutting cylinder 27 is fixedly provided with a guiding die base 22, and a reduction motor 26 is fixedly arranged at the rear part of the inner end surface of the guiding die base 22. A transmission card shaft 23 is fixedly arranged at the output end of the reduction motor 26. An active bevel gear 25 is arranged at the outer end surface of the transmission card shaft 23 near the middle, and two groups of driven bevel gears 24 are arranged at the inner end surface of the guiding die base 22 near the active bevel gear 25. Guiding lead screws 21 are fixedly arranged at the inner end surfaces of the two groups of driven bevel gears 24.

[0027] The die-cutting device 3 includes a ball slide 31, two groups of guiding card seats 32 are arranged on the lower end surface of the ball slide 31, a connecting handle 33 is elastically and slidably clamped in the inner end surface of the guiding card seat 32 through a return spring 37, and two groups of plug-in card shafts 36 are arranged at the inner end surface of the connecting handle 33. A positioning card seat 35 is fixedly clamped on the lower end surface of the ball slide 31, and a die-cutting block 34 is fixedly arranged at the center of the lower end surface of the positioning card seat 35.

[0028] The guiding die base 22 is in fitting connection with the inner walls of the two groups of fixed bases 5, which can effectively improve the stability of the subsequent vertical displacement of the guiding die base 22 between the two groups of fixed bases 5.

[0029] The active bevel gear 25 is meshed and connected with the two groups of driven bevel gears 24.

The driving bevel gear 25 can drive the two driven bevel gears 24 to drive the two guiding lead screws 21 to rotate synchronously. The two guiding lead screws 21 can drive the two ball slides 31 and the alignment card seats 35 to perform centripetal and centrifugal displacements through the ball slides 31 synchronously, thereby adjusting the die-cutting width of the die-cutting block 34 on the raw material. If it is necessary to quickly replace different models of die-cutting blocks 34, at this time, the user can hold the connecting handle 33, and then pull the connecting handle 33 outwards, so that the connecting handle 33 can drive the inserting card shaft 36 to separate from the alignment card seat 35, thereby facilitating the subsequent quick and convenient replacement operation of the die-cutting block 34.
