Packaging box forming device {FORMING DEVICE FOR PACKAGIN BOX}

The present invention relates to a packaging box forming device.

The packaging box forming device includes a wrap-around packaging device for packaging objects to be packaged in a single box, and a sliding packaging box forming device for packaging objects to be packaged in a packaging box and an outer box.

The wrap-around packaging device folds and joins cardboard to form a box body with upper and lower flaps, folds and joins the lower flap of the box body to close the lower part of the box body, and then wraps the packaging material in the box. After being accommodated inside, the upper part of the box body is closed by folding and joining the upper flap of the box body to complete the packaging of the packing material.

The sliding packing box molding device loads the packing material on cardboard, folds and joins the cardboard to form a packing box, which is the final molding form, and then inserts the packing box into the outer box to complete the packaging of the packing material.

However, in the conventional sliding packaging box forming apparatus, only the outer circumference of the cardboard is fixed with a guide and molded into a packaging box shape. Therefore, the prior art has a problem in that the molding defect rate of the packaging box, which is the final molded product, increases as symptoms occur in which both sides of the cardboard in the left and right directions or both sides in the front and rear directions are bent inward.

In addition, in the prior art, after the to-be-packaged material is loaded on a cardboard, the cardboard is molded into a packaging box shape. Therefore, in the prior art, in the process of forming the cardboard into a packaging box shape, both the cardboard and the packaging material were damaged.
