Production method of fully open packaging box

Abstract

The invention provides a production method of a full-open packaging box, step 1), the side panels on the left and right sides of the core surface part are folded, the folding angle is 170°-180°, and after the folding is completed, the side panels of the core surface part are folded The board is opened and restored to its original shape; step 2), glue the glue in the glue storage groove on the rubber roller to the core bottom part; step 3), form the bottom block part; step 4), form the inner box part; use adhesive tape, align the core The intersection of the four side plates of the surface part and the four side plates of the core bottom part is fixed; step 5), the glue in the glue storage groove on the rubber roller sticks to the inner surface of the box surface part; step 6), Complete the paste box; the air press presses the four sides of the packaging box; step 7), perform the first water balance operation on the packaging box; step 8), take out the paste box mold. The production method of the invention can improve the consistency of the dimension of the packaging box, and reduce the degree of depression or protrusion on the box cover and box bottom of the packaging box.

Description

technical field [0001] The invention relates to the technical field of cigarette case packaging, in particular to a production method of a full-open type packaging case. Background technique [0002] China Utility Model Patent "Paper Filled Corner Fully Open Packaging Box" application number: 201520704779.5, the fully open packaging box in this patent includes: box surface, core surface, core bottom and surrounding edge. [0003] The existing full-open packaging boxes are generally produced by hand-gluing. The main production process is as follows: First, fold each part along the indentation line, and apply glue on the four sides of the "core bottom" part. Then, wrap the "shroud" part around the gluer mold and glue it together with the "core bottom" part to form the "bottom block" part. Next, place the "core face" part over the "bottom block" part to form the "inner box" part. Apply glue to the back of the "box surface" part, fold and wrap the glued "box surface" part on t...

Problems solved by technology

The full-open packaging box produced by this process has poor batch forming size consistency, and the bottom and lid of the box are prone to obvious depressions or protrusions. When packaging on an automatic packaging machine, the packaging box often gets stuck on the conveyor belt. , the box cover cannot be opened, the packaging box is skewed, etc., and it is impossible to realize mass packaging production
