The direction of the left and right material toward the two sides of the track is a horizontal direction perpendicular to the conveying direction of the tape material 200, for example, when the X axis is the conveying direction of the tape material 200 and the Z axis is the direction toward the ground where the discharge conveying mechanism 10 is installed, the Y axis is the direction of the left and right material toward the two sides of the track. In this embodiment, generally, the tape material conveyed by the discharge conveying mechanism 10 is a waste tape that has been subjected to blanking, the finished tape that has been subjected to blister forming and is guided by the feed guiding mechanism 20 is punched between the discharge conveying mechanism 10 and the feed guiding mechanism 20 to separate the blister finished product from the mold at the middle bottom, and then the separated blister finished product is taken out by the adsorbing device.
