The rack 17, the longitudinal bevel gear 16 and the transverse bevel gear 15 are such that the relative height between the sink 3 and the counter knife 1 is unchanged. Specifically, in the implementation process, the lifting distance of the converging groove 3 is always the same as the lifting distance of the auxiliary knife 1 by using the transmission ratio among the rack 17, the longitudinal bevel gear 16, the transverse bevel gear 15, the adjusting screw rod 9 and the adjusting screw sleeve 10, and of course, the lifting distance of the converging groove 3 and the lifting distance of the auxiliary knife 1 can be set to be in other fixed proportion forms.

Wherein, a slide bar 18 is fixed on the rack 17, the slide bar 18 penetrates through the cantilever 8, and a pressing spring 19 is arranged between the slide bar 18 and the cantilever 8. The pressing spring 19 maintains a state of pressing down the rack 17, and in turn, transmits a pressing force to the adjusting screw 9 through the longitudinal bevel gear 16 and the transverse bevel gear 15, and finally, the pressing force is transmitted to the sub-head through the adjusting screw 9 and the adjusting screw sleeve 10. The pressing force is opposite to the supporting force of the laminated prepreg to the confluence groove 3, and the stability of the auxiliary knife 1 is sequentially improved. Meanwhile, the auxiliary knife 1 is prevented from jumping or fluctuating up and down when the precut groove is cut under the action of gravity, so that the cutting stability is improved.
In another aspect, the present application also provides a cutting device for laminated prepregs, which includes the above laminated prepreg cutting tool assembly, a cutting platform 20, and clamping plates 21 disposed on two sides of the cutting platform 20 and having tops flush with the laminated prepregs.
The cutting platform 20 and the clamping plate 21 form a fixture for supporting and fixing the cut laminated prepreg. The clamping plates 21 clamp the laminated prepreg from both sides thereof.
The clamping plate 21 is provided with grooves for the main knife 2 and the auxiliary knife 1 to pass through, the end face of the clamping plate 21 is of a right trapezoid structure, the outer side face of the clamping plate is an inclined waist face, and the auxiliary knife 1 is driven to automatically lift when the confluence groove 3 slides on the waist face.
Specifically, before cutting, when the main blade 2 and the sub blade 1 move onto the laminated prepreg on the cutting deck 20, the confluence groove 3 slides on the cutting deck 20 to the inclined waist surface of the upper clamping plate 21, slides on the top of the upper clamping plate 21 through the waist surface, and then moves to the top of the laminated prepreg.
In the process, the confluence groove 3 is lifted, the adjusting screw rod 9 acts through the cooperation of the rack 17, the longitudinal bevel gear 16 and the transverse bevel gear 15, and the adjusting screw rod 9 enables the auxiliary knife 1 to automatically rise to a certain height according to a preset transmission ratio through the adjusting screw sleeve 10 and the auxiliary knife rest.
For example, when the preset gear ratio is: height of the sink 3 rises: when the auxiliary knife 1 is lifted to a certain height=3:1, the auxiliary knife 1 can be lifted to one third of the height when the confluence groove 3 is lifted to a certain height, and then the depth of the precut groove cut by the auxiliary knife 1 is one third of the thickness of the laminated prepreg.
Accordingly, since the top of the clamping plate 21 is arranged at the same height as the laminated prepreg, the confluence groove 3 slides from the cutting platform 20 to the waist surface of the clamping plate 21, and the upper surface of the cutting platform 20 is at the same height as the bottom of the laminated prepreg.
Therefore, before cutting laminated prepregs with different thicknesses, only the height of the clamping plate 21 is required to be adjusted so that the top height of the clamping plate 21 is flush with the top surface of the laminated prepreg, and the laminated prepreg cutting device can automatically adjust the height of the auxiliary knife 1 according to the thickness of the laminated prepreg and the preset transmission ratio to realize that the depths of precuts cut by the auxiliary knife 1 are the same proportion of the thickness of the laminated prepreg for the laminated prepregs with different thicknesses.
