[0035] In some embodiments, the height of the table surface on the side of the discharging opening b close to the feeding end of the workbench 1 (i.e., the right side of the discharging opening b in this embodiment) is slightly higher than the height of the table surface on the side of the discharging opening b close to the discharging end of the workbench 1 (i.e., the left side of the discharging opening b in this embodiment), so that the cut paperboard passes through the discharging opening b more smoothly to complete discharging. Figure 2 Figure 2 In some embodiments, the height of the table surface on the side of the discharging opening b close to the feeding end of the workbench 1 (i.e., the right side of the discharging opening b in this embodiment) is slightly higher than the height of the table surface on the side of the discharging opening b close to the discharging end of the workbench 1 (i.e., the left side of the discharging opening b in this embodiment), so that the cut paperboard passes through the discharging opening b more smoothly to complete discharging.

[0036] As shown in Figure 1 , Figure 3 , the pressing plate 5 is arranged on the side of the discharging opening b close to the feeding end of the workbench 1.

[0037] ​As a preferred embodiment, the support beam 3 is provided with a support frame 7 which is liftable by the second electric hydraulic push rod 32, and the support frame 7 is arranged at one side of the blanking opening b close to the discharging end of the workbench 1.

[0038] As shown in Figure 4 、 Figure 5 , a positioning baffle 71 is adjustably arranged at one side of the support frame 7 which faces the pressing plate 5. Specifically, two threaded holes are formed at two ends of the support frame 7 respectively, and two driving screws 72 are screwed into the two threaded holes respectively. One end of the driving screw 72 is rotatably connected to the positioning baffle 71. By rotating the driving screw 72, the distance between the support frame 7 and the positioning baffle 71 can be adjusted.

[0039] As shown in Figure 5 , in some embodiments, a support 732 is formed at one side of the support frame 7 which faces away from the positioning baffle 71, and the support 732 is provided with a threaded hole, and a screw 731 is screwed into the threaded hole.
