The electromagnet 29 on the left side of the slide acts on the magnetic force on the magnet column 28 to make the rotating plate 27 rotate leftward around the axis, so that the outer end of the rotating plate 27 contacts the upper inclined surface of the left inclined slide groove on the slide groove cylinder 22, so that the channel at point C on the slide groove is opened, and the cylinder 24 is extended during operation, and the cylinder 24 drives the cylindrical shaft 25 to rise. Due to the cooperation between the positioning column 26 and the left vertical slide groove on the slide groove cylinder 22, the cylindrical shaft 25 first rises vertically, and the cylindrical shaft 25 drives the transposition frame 21 to rise and disengage from the cross groove on the support plate 13, so that the laminated board door is separated from the support plate 13, and then the positioning column 26 enters the inclined slide groove on the left side of the slide groove cylinder 22. Due to the action of the inclined slide groove, The cylindrical shaft 25 rotates in the chute cylinder 22.
