Its function is that through the arrangement of the interlocking gear, the transmission gear, the connecting block, and the driving cylinder, when the driving cylinder pushes the connecting block to perform linear motion, the linear motion of the transmission rack is converted into the circular motion of the rotating shaft where the transmission gear is located around its own axis through the meshing of the transmission rack on the connecting block and the transmission gear, and the opening and closing action of the two clamping arms is realized through the meshing of the two interlocking gears and the fixed connection between the rotating shaft and the corresponding clamping arm.

[0008] Furthermore, the driving cylinder is arranged on the side of the mounting platform facing away from the clamping arm, the connecting block penetrates the mounting platform, and a guide hole for the connecting block to move is arranged on the mounting platform, and the extending direction of the guide hole is parallel to the driving direction of the driving cylinder.

[0012] Furthermore, the vacuum suction cups and the end faces of all the support columns on the same connection frame away from the corresponding connection frame are in the same plane.

At this time, the plane formed by the two rotating shafts 5 is perpendicular to the paper tray. After that, the paper tray is moved down to an appropriate height, and the driving cylinder 404 is started to gradually close the two clamping arms 2 until the two clamping arms 2 clamp the paper tray. At this time, the vacuum suction cups 3 and the support columns 9 are both attached to the surface of the paper tray. After that, the two vacuum suction cups 3 are started to adsorb different paper trays respectively, and then the driving cylinder 404 is started again to gradually open the two clamping arms 2, so that the two vacuum suction cups 3 are gradually separated, thereby achieving the effect of automatically separating the vacuum suction cups 3, and high working efficiency.
