Automatic inner edge-wrapping device of packaging box

Abstract

The invention relates to an automatic inner edge-wrapping device of a packaging box. The automatic inner edge-wrapping device comprises an fixed inner die, a bending mechanism, a combined telescopic frame, a moveable inner die and a power mechanism, wherein the fixed inner die is arranged on a big beam, so a box body sleeves the fixed inner die; the bending mechanism is used for bending the inner wrapping edge of an outer paper towel towards the inner side direction of the box body; the combined telescopic frame is arranged on the big beam; one end of the moveable inner die is arranged in the combined telescopic frame; the outline shape of the moveable inner die is matched with the inner cavity shape of the box body; the power mechanism is used for driving the moveable inner die to reciprocate along the route defined by the combined telescopic frame. Due to the fact that the bending mechanism and the moveable inner die are matched ingeniously, and under the driving of the moveable inner die, the bending mechanism bends the inner wrapping edge towards the inside before the moveable inner die is in contact with the inner wrapping edge of the outer paper towel, and the moveable inner die can further conveniently bend the inner wrapping edge towards the interior of the box body, so the inner wrapping edge is finally stuck to the inner surface of the box body, the whole process is automatically operated, the operation on the inner wrapping edge can be finished within seconds, and the efficiency is very high.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to an automatic inner edge wrapping device for a packaging box. Background technique [0002] Most of the existing packaging boxes will be pasted with a layer of outer paper printed with beautifully designed patterns, texts, etc. on the outer surface of the box body made of cardboard or other relatively hard materials. In the existing process of pasting the outer paper, a uniform glue layer is first formed on the inner surface of the outer paper, and then the main body of the box is aligned and placed on the predetermined position on the inner surface of the outer paper, and then the main body of the box can be combined with the The outer paper is fed into the automatic laminating machine, and the outer paper is closely and precisely attached to the box body. In order to facilitate the outer paper to fit better with the box body at the opening of the box body, the end of the oute...

AI Technical Summary

Problems solved by technology

In order to facilitate the outer paper to fit better with the box body at the opening of the box body, the end of the outer paper corresponding to the opening of the box body will be provided with a wrapping edge of appropriate width, and these wrapping edges need to be folded into the inside of the box body and fitted However, the existing automatic laminating machine can only complete the lamination between the outer paper and the outer surface of the box main body, and cannot automatically realize the laminating process of these wrapping edges, but can only be processed through After being processed by the automatic laminating machine, the edge is manually folded into the inside of the box body and pasted on the inner surface of the box body, which makes the efficiency of the entire box assembly and molding relatively low
