Description

Base structure for molding packaging box Technical Field The utility model relates to a base structure for forming a packaging box. Background The paper packing box is applied to various industries, the paper packing box is a piece of paper board (called as a planar packing box for short) which is unfolded before forming, when the paper packing box is formed by forming equipment, a pushing disc on the forming equipment pushes the planar packing box from the top of a forming frame to the bottom of the forming frame from top to bottom, a space enclosed by the forming frame can drive the planar packing box to be deformed from the planar shape into a box body shape with an open top, and the pushing disc on the forming equipment pushes the packing box with the open top into a bottom support on a production line for the next forming procedure. The size of the existing shaping frame for shaping the packing box is usually fixed, and the packing box of different sizes needs the shaping frame adaptation that corresponds, has not only increased the cost of shaping frame, brings very big trouble for the transfer of the packing box of different sizes moreover, influences production efficiency, and in addition, the shaping frame of present shaping is carried out to the packing box, pushes away the dish and pushes away the planar packing box from the top of shaping frame to the shaping frame when enclosing the space that covers, the inward flange of the opening part of shaping frame scratch planar packing box easily, causes the production of defective products.
