Pressing plate mechanism for metal heat insulation laminboard cutting machine

The utility model relates to a pressing plate mechanism for a metal heat insulation laminboard cutting machine. The pressing plate mechanism comprises a cylinder with a cylinder rod telescopic vertically downwards. The pressing plate mechanism is characterized in that a plate frame is installed on the cylinder rod of the cylinder through a screw and is internally provided with a cavity, the lower portion of the plate frame is provided with an opening, the cross section of the plate frame is in a C shape, a core board is arranged in the cavity of the plate frame, the lower portion of the core board is connected with a rubber pressing plate, the shape of the rubber pressing plate is matched with the opening, the rubber pressing plate extends out of the opening, and a plurality of springs are arranged between the core board and the plate frame. According to the pressing plate mechanism, through the arrangement of the springs, pressure of the cylinder indirectly acts on a metal heat insulation laminboard, the pro
