The fourth driving member 42 is a motor, and the fourth driving member 42 drives the driving sprocket 41 to rotate, so as to drive the driving chain 40 to rotate.
After the conveyer transports the paper board to the lower template 7, the driving chain 40 rotates until the driving plate 59 on the driving chain 40 abuts against the paper board, and the paper board is pushed to a preset position in front of each other. Thereby ensuring that the paperboard can be ready for die cutting. After the die cutting is finished, the driving chain 40 continues to rotate, and the driving plate 59 continues to push the paper board forwards, so that the paper board is pushed down from the lower template 7, and the discharging is finished.
Referring to fig. 7 and 8, the material receiving assembly 39 includes a material receiving frame 43, a material receiving plate 44 for placing the cardboard, and a fourth driving mechanism for driving the material receiving plate 44 to move in the vertical direction. The material receiving plate 44 is provided with a baffle plate 62 at an end remote from the drive chain assembly 38. The cardboard discharged from the lower template 7 falls onto the material collecting plate 44, and the fourth driving mechanism drives the material collecting plate 44 to move downwards, so that the uppermost cardboard placed on the material collecting plate 44 is always at the same height. The paperboard pushed from the lower template 7 can be stably stacked on the material receiving plate 44.
The fourth drive mechanism also comprises four drive chain sets 21. The four transmission chain groups 21 respectively correspond to four corners of the blanking plate. The drive chain set 21 includes a drive chain 26, a drive sprocket 27 and a motor.
