Paperboard incoming material pre-folding method, paperboard box pre-folding process and paperboard box pre-folding device

Abstract

The invention discloses a paperboard incoming material pre-folding method, a paperboard box pre-folding process and a paperboard box pre-folding device. The paperboard incoming material pre-folding method comprises the following steps of: providing a solid body with edges and corners, aligning to-be-folded lines of the paperboard incoming material with the edges of the solid body and pressing, andfolding the paperboard incoming material along the edges to obtain folding marks; and enabling two adjacent surfaces of an indentation line to be attached to the surface where the edges and corners of the solid body are located, taking out the solid body, and flattening and folding the two adjacent surfaces along the indentation line. The paperboard incoming material pre-folding method, the paperboard box pre-folding process and the paperboard box pre-folding device are aimed at solving the problems that in the prior art, after a product is loaded into a manually-manufactured packaging box, the structure is loose, certain packaging boxes can even be automatically opened, and inconvenience is brought to product use.

Description

technical field [0001] The invention relates to the technical field of card box production, in particular to a prefolding method for cardboard incoming materials, a prefolding process for card boxes and a prefolding device for card boxes. Background technique [0002] The stiffness of the jammed paper is relatively large. If the size of the folded surface is small, the structure of the adjacent surface associated with the folded surface will be loose due to the tension of the paper after the paper is formed. The card box is formed from cardboard and glued between overlapping sides. No glue is applied to the two folded sides of the card box. After the packing box is filled with articles, the storage cavity is closed by the joint action of the plug and the jack: the folding surface is folded to cover the opening of the storage cavity, the two adjacent surfaces are overlapped, and the plug and socket are inserted. At present, the means of packaging products with this package ...
