The shape of the plate table and the press-cutting mechanism of the automatic flat die-cutting machine are flat. When the plane of the plate table and the platen are in the vertical position, it is a vertical flat-bed die-cutting machine. When the die-cutting machine is working, the pressure plate is pressed to the plate by the transmission to put pressure on the plate table. The different movement trajectories of the pressing plate can be divided into two categories: one is that the pressing plate swings around the fixed hinge, so at the moment of starting molding, there is a certain inclination between the working surface of the pressing plate and the stencil surface, so that the die-cutting plate can be cut into the lower part of the cardboard earlier. , which is easy to cause the phenomenon that the pressure on the lower part of the die plate is too heavy and the upper part is not completely cut through. In addition, the component force of the die-cutting pressure can also cause lateral displacement of the cardboard. When another type of pressing plate motion mechanism is in operation, the pressing plate, driven by the connecting rod, first takes the cylindrical roller as the fulcrum and swings on the flat guide rail of the machine base. When it is in a parallel position, press it parallel to the die-cutting plate in a translational manner.
