[0035] Working principle: When the flattening device 2 is used for a long time, powder will remain inside it. At this time, the powerful fan 9 can be started. The powerful fan 9 draws air into the recovery box 4 through the negative pressure pipe 10, thereby generating negative pressure inside the recovery box 4, and then draws air into the recovery pipe 6 through the conveying pipe 8. The recovery pipe 6 draws air into the air collecting hood 5 through the connecting pipe 7, thereby absorbing the powder remaining on the surface of the flattening device 2, so that it enters the recovery box 4, is filtered by the coarse screen 13 and the fine screen 14, and then falls to the bottom of the drop port 28 for collection, and then opens the second box door 29 for collection. At the same time, when the coarse screen 13 and the fine screen 14 need to be cleaned, it is only necessary to pull the two synchronous plates 20. The synchronous plate 20 pulls the plug rod 18 to move through the pull rod 19 to disengage it from the fastening groove 15, and then the fixed plate 11 can be removed. After the cleaning is completed, the reverse operation can be performed.
