Bubble extrusion treatment device during prepressing of laminated glass

The utility model discloses a bubble extrusion processing device during laminated glass prepressing, which comprises a bottom plate and side plates arranged on two transverse sides of the bottom plate, a heating plate is arranged on the bottom plate, a cross beam plate is arranged between the two side plates, and a sliding mechanism is arranged between the cross beam plate and the two side plates. The sliding mechanism is used for enabling the cross beam plate to longitudinally slide along the bottom plate, a mounting frame is arranged below the cross beam plate, two rolling shafts are transversely arranged on the mounting frame, height differences exist between the axes of the two rolling shafts and the surface of the heating plate, and a lifting mechanism is arranged between the cross beam plate and the mounting frame; and the lifting mechanism is used for vertically lifting the mounting frame. The two rolling shafts with the vertical height difference are matched to extrude the upper glass, so that bubbles
