in this embodiment, unloading exhaust apparatus 5 is including being used for inhaling the unloading module 51 of blowing board 7, being used for placing the useless die block 52 of wasting discharge of flitch 7 and being used for blowing off the structure 54 of blowing of waste material, be provided with the terrace die 522 corresponding with the waste material of flitch 7 on the useless die block 52 of wasting discharge, work as the second is got and is put subassembly 512 and absorb and drive flitch 7 and relative when wasting discharge die block 52 downstream, terrace die 522 upwards ejecting the removal of waste material on with the flitch 7, the structure 54 of blowing is located the side of wasting discharge die block 52 is in order to be used for blowing off the waste material that is ejected. Therefore, by utilizing the pushing force generated when the second taking and placing component 512 presses down to take materials, the material plate 7 is pushed to move downwards, and the male die 522 on the waste discharge bottom die 52 is matched to eject and remove waste materials on the material plate 7 upwards, so that waste discharge of the material plate 7 after transverse cutting is realized, the structure is simpler and simpler, the waste discharge upper die 53 is not needed, and the overall weight of the second taking and placing component 512 is reduced; meanwhile, when the flitch 7 of different specifications needs to be produced, only the waste bottom die 52 needs to be replaced, so that the labor cost and the die opening cost are saved.

Wherein, in order to facilitate the upward ejection of the scraps, the size of the male die 522 is smaller than that of the scraps on the flitch 7.

Preferably, the number of the punches 522 corresponds to the number of the scraps on the flitch, and each of the punches 522 corresponds to one of the scraps.

In this embodiment, the structure of the blanking module 51 is the same as that in embodiment 1, and the blanking module also includes a first pick-and-place assembly 511 and a second pick-and-place assembly 512, and the second pick-and-place assembly 512 is also connected to the main structure of the blanking module 51 through a hold-down cylinder 513, which is not described herein again.

In this embodiment, when the first picking and placing component 511 presses down at the position of the die device 4 to suck the material plate 7, the second picking and placing component 512 pushes the material plate to press down, during the pressing process, the male die 522 ejects and removes the waste material on the material plate 7 upwards, the air blowing structure 54 starts to work, blows away the ejected waste material, and after the second picking and placing component 512 presses down to the limit position, the suction cups on the second picking and placing component 512 suck the material plate 7 after the waste discharge is completed.

In conclusion, the automatic positioning and die cutting production line for the packing box flitches combines front end conveying, automatic positioning, feeding, stamping, waste discharging and blanking and rear end conveying, positions the flitches 7 through the automatic positioning device 2, and performs waste material clearing and blanking on the flitches 7 subjected to stamping by the blanking and waste discharging device 5, so that full-automatic assembly line operation of the loading and stamping of the packing box flitches is realized, stamping accuracy is improved, and production efficiency is improved.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
