Since the first roller shaft 21 and the second roller shaft 22 are both It is cylindrical, so the diaphragm 400 is prevented from being damaged when the swing rod 20 drives the diaphragm 400 to swing in an arc. When the swing rod 20 drives the diaphragm 400 to swing, the diaphragm 400 can pass through the guide channel 20a to continue discharging, and can also be driven by the swing rod 20 to swing in an arc relative to the stacking table 220, thus realizing the diaphragm 400 back and forth folding. Preferably, the second driving device 50 and the swing rod 20 are respectively arranged on two sides of the frame 10 , and the output end of the second driving device 50 passes through the frame 10 and is connected with the connecting rod 60 .
