The existing box gluing process is to fold a die-cut box original cardboard into two layers without a hollow in a carton folding and gluing machine to apply glue. After the glue is applied, the glue is pressed dry on a press at the rear end. The existing carton folding and gluing machine puts pressure on the glued part after the box is glued, but the three-dimensional box cannot be stressed during the whole box glue production process, otherwise the box will be deformed, so the existing carton folding and gluing machine can only be suitable for installation The above process produces flat boxes and cannot be used for glued three-dimensional boxes. The current three-dimensional boxes are all made by hand, using a special mold to manually fold the original cardboard to form a three-dimensional shape, and then use a hot melt glue gun to manually glue for production. This kind of production method is inefficient and cannot meet the customer’s delivery date, and the quality of manual paste box is unstable, which is prone to quality problems such as open glue, overflow glue, and low glue.

In view of the shortcomings of the existing technology, the technical problem to be solved by the present utility model is to provide a three-dimensional carton folding and gluing machine that is efficient and guarantees product quality. In order to overcome the shortcomings of the existing technology, the technical scheme adopted by the utility model is a three-dimensional carton folding and gluing machine, which is used to fold the pre pressed paperboard with creases into a three-dimensional box shape and paste tightly. The stereo carton folding and gluing machine comprises a flowing water feeding belt for transferring workpieces, a shaper arranged upstream of the flowing water feeding belt, and a box pressing device arranged downstream of the flowing water feeding belt. The shaper comprises a flanging part arranged on the side of the flowing water feeding belt, and a hanging core plate arranged parallel to the upper side of the flowing water feeding belt A part of the suspension core plate is embedded in the forming end with clearance, and another part of the suspension core plate is embedded in the turnover part with clearance.
