The bottom of the vibrating frame 22 close to the feeding device 3 is rotatably connected to the base frame 21. The side of the vibrating frame 22 away from the feeding device 3 is connected to the base frame 21 through elastic members (e.g. springs). The bottom of the vibrating frame 22 is connected to a vibrator 222. Of course, in other embodiments, the vibrating frame 22 can be connected to the base frame 21 only through elastic members.
[0051] Further, the screen 221 is connected to a partial position of the bottom of the vibrating frame 22 and is located in the middle of the flow direction of the blank 200 inside the vibrating frame 22.
