Automatic packaging carton
Technical field
The utility model relates to technical field of automation in industry, particularly relates to a kind of automatic packaging carton.
Background technology
In automation or semi-automatic packing of product workshop, packing joint sealing carries out glue by automation compress to have brought.Normal packet vanning, often because four distinct faces of its upper surface easily extrude dislocation under pressure, causes sealing after joint sealing completes irregular, thus the overall appearance of impact packaging.In addition, because packing chest material therefor is generally fluting board, easily turned down when packing work or torn, not only causing packaging rework rate higher, reduce work efficiency, also damaged packing chest, added packing cost to a certain extent.
Summary of the invention
The utility model overcomes prior art problem Problems existing, provides a kind of automatic packaging carton, not only reduces packaging and to do over again phenomenon, also reduce damage and the waste of packing chest, thus ensure that the overall appearance degree of packaging.
The utility model is achieved through the following technical solutions:
Automatic packaging carton, comprise a paper box body, described casing is cuboid, comprise four sides and a bottom surface, also comprise novel upper surface, described upper surface is by the first upper surface, the second upper surface, and the integrative-structure that two identical joint faces are formed jointly, is provided with breach and turn-line at described joint face.
Described breach is inverted trapezoidal or semicircle.
After described joint face is folding along described turn-line, the first upper surface and the second upper surface are closed up.
Described joint face is symmetrical structure.
Compared with prior art, a kind of automatic packaging carton of the utility model solves problems of the prior art.Automatic packaging carton, described upper surface is that upper surface is by the first upper surface, the second upper surface, and the integrative-structure that two identical joint faces are formed jointly, the extruding inconsistent phenomenon caused because of the effect of wrapping machine pressure when effectively can be reduced in automatic packaging joint sealing; And be provided with breach and turn-line at described two identical joint faces, by turnover, described two identical joint faces serve fixation to the first and second upper surfaces, thus not only reduce packaging and to do over again phenomenon, improve packing work efficiency, also reduce damage and the waste of packing chest, ensure that the overall appearance degree of packaging.

Detailed description of the invention
Below in conjunction with specific embodiment, a kind of automatic packaging carton of the utility model is elaborated further, refers to Fig. 1.
As a kind of detailed description of the invention, automatic packaging carton, comprise a casing, described casing is cuboid, comprise four sides 1 and a bottom surface 2, also comprise a novel upper surface 3, the integrative-structure that described upper surface 3 is made up of the first upper surface 31, second upper surface 32 and two identical joint faces 4, be provided with breach 5 and turn-line 6 at described joint face 4.
As preferably, described breach 5 is in inverted trapezoidal or semicircle.Described inverted trapezoidal breach is symmetrical structure, turns down joint sealing when being convenient to packaging.
After described joint face 4 is folding along described turn-line 6, first upper surface 31 and the second upper surface 32 are closed up, use tape-stripping joint sealing, form the rear upper surface of packaging, namely seen upper surface.
Described joint face 4 is symmetrical structure.
Described two joint faces 4 can fold along described turn-line 6.After folding, the first upper surface 31 and the second upper surface 32 are fixed, even if be also not easily extruded under the effect of wrapping machine pressure and misplace.
As another kind of embodiment, described breach 5 is set to rectangle or other shapes.All the other implementation contents are identical with last embodiment, do not repeat them here.
Compared with prior art, a kind of automatic packaging carton of the utility model solves problems of the prior art.Automatic packaging carton is the first upper surface, the second upper surface by described upper surface, and the integrative-structure design of two identical joint faces, the extruding inconsistent phenomenon caused because of the effect of wrapping machine pressure when effectively can be reduced in automatic packaging joint sealing.And be provided with breach and turn-line at described joint face, by turning down along described turn-line, described two joint faces serve fixation to the first and second upper surfaces jointly, thus not only reduce packaging and to do over again phenomenon, improve packing work efficiency, also reduce damage and the waste of packing chest, ensure that the overall appearance degree of packaging.
More than describe and be only specific embodiment of the utility model, forgive and can understand, under the prerequisite not departing from the utility model design, all should be included within technical conceive of the present utility model simple modification of the present utility model and replacement.
