Description
Technical Field
The utility model relates to a tobacco storage facilities especially relates to a circulated piece cigarette honeycomb case of high strength.
Background
The whole box of the tobacco lamina is a packaging box for containing the tobacco lamina, the existing carton of 200kg redried tobacco lamina is generally formed by sheathing an inner box and an outer box, has the advantages of environmental protection, easy folding, convenient transportation and the like, basically replaces a plywood packaging box, and mainly comprises a corrugated carton and a honeycomb carton.
In the prior art, the inner box and the outer box of the corrugated case both adopt seven layers of corrugated boards to ensure that the corrugated case meets the compressive strength not lower than 2.65 multiplied by 10 specified in tobacco industry standard YC/T137.1-2004 corrugated case package of redried strip tobacco package of China4N, but a large amount of base paper is needed for producing seven-layer corrugated boards, so that the weight of the carton is large, the cost is high, and the shipping cost and the labor cost are increased due to large volume and weight.
At present, the indentation of corrugated container board turns over a structure and mainly has brokenly the paper indentation and bumps two kinds of paper indentation among the prior art, bump the paper indentation and realize through adopting the line ball wheelset, have among the prior art to improve the structure of line ball wheelset and can positive and negative folding explosion-proof line ball wheelset on a rip cutting line press like CN205130481U, and then prevent the phenomenon that the cardboard explodes the line in the indentation in-process, but because the sandwich structure and the thickness of honeycomb cardboard all are different with corrugated container board, it is natural, the indentation that is used for corrugated container board among the prior art turns over a structure and is not suitable for the honeycomb cardboard.
Because the stable hexagonal structure of the honeycomb core has excellent capability of bearing axial load, the honeycomb paperboard has the outstanding characteristics of high rigidity, high flat-pressing strength and strong bending resistance, and meanwhile, the bending resistance of the honeycomb core has the characteristics of anisotropy and nonuniformity, and folds are usually formed along the edges of the honeycomb core instead of straight lines when the honeycomb paperboard is bent; the indentation of the honeycomb paperboard in the prior art is easily damaged due to strength damage when in use.
Although the inner box and the outer box of the existing honeycomb carton utilize the honeycomb structures thereof, the compression strength of the carton is improved, for example, in the sheet tobacco inner box, the sheet tobacco whole box and the sheet tobacco whole box processing method disclosed in CN107323864A, because the side wall and the folding page at the bottom of the folding structure are formed by flat pressing, the strength of the connecting structure between the folding page at the bottom and the side wall is easily damaged due to slotting by slitting pressing lines, and further the honeycomb carton for containing the sheet tobacco cannot meet the requirement of the carrying capacity of the carton in the sheet tobacco storage process; and above-mentioned whole case of piece cigarette is easy to be because of the impaired unable because of the structure when recycling, satisfies the compressive strength requirement of smoke box, leads to unable recycling once more.

The utility model relates to a high strength circulated slice cigarette honeycomb case's theory of operation and application method:
the utility model discloses a high strength circulated piece cigarette honeycomb case, its curb plate and shake a turnover structure of lid by at least 2 enstrophe indentation, at least 1 enstrophe indentation constitute, when folding into honeycomb piece cigarette case by the honeycomb cardboard after the creasing of fabric wheel, the shake lid of honeycomb piece cigarette case turns over to the curb plate medial surface, until the shake lid becomes 90 with the curb plate medial surface, adopt the packing of gluey sealing tape to form semi-closed square open structure; when the honeycomb piece smoke box is used, tobacco leaves are generally put into the inner smoke box, and after the inner smoke box is packaged by wearing the tobacco leaves, the outer smoke box is sleeved outside the inner smoke box; after the honeycomb piece smoke box is used, the rocking cover is usually turned over towards the turning-over outer side face, in the embodiment 1, a first inward-turning indentation between the rocking cover and the side plate is slightly deformed, and a second inward-turning indentation and an outward-turning indentation are greatly deformed, so that the rocking cover can be conveniently turned over from a position which is 90 degrees away from the inner side face of the side plate to any angle between the rocking cover and the outer side face of the side plate (such as the rocking cover is turned over to be flat with the outer side face of the side plate) to be attached to the outer side face of the side plate, and the honeycomb piece smoke box can; when the folded honeycomb paperboard is reused to form the cigarette box, the rocking cover is turned over until the rocking cover and the inner side surface of the side plate form an angle of 90 degrees (in embodiment 1, the second inward-turning indentation 202 between the rocking cover and the side plate is deformed slightly, and the first inward-turning indentation 201 is deformed greatly, so that when the rocking cover is turned over inward, the honeycomb paperboard is turned over but the structural strength of the honeycomb paperboard is not affected), and the honeycomb paperboard is packaged by using an adhesive tape to form a semi-closed square opening structure, so that the cigarette box can be reused.
After the high-strength recyclable tobacco lamina honeycomb box is used up, the side plates of the side walls are folded along the inward bending indentation 302 and the outward bending indentation, if the side walls are continuously folded along the bending direction along the inward bending indentation 302 and the first outward bending indentation 303 in the embodiment 1, the side walls which are enclosed to form a square structure can be folded to form a straight line shape, and then the storage space is saved. When the high-strength recyclable cigarette carton honeycomb box is reused, the side plates are bent by 90 degrees by utilizing the second outer bending indentation 304 and the inner bending indentation 302 to form a square structure again, and the requirements on the compressive strength of the high-strength recyclable cigarette carton honeycomb box in the using process can be met due to the fact that the depths of the first outer bending indentation 304 and the second outer bending indentation 304 are different.
The utility model relates to a high strength circulated piece cigarette honeycomb case, along with the change of high strength circulated piece cigarette honeycomb case thickness for the preparation, the angle that the enstrophe indentation of inner box 100 and outer container 400 and the degree of depth of the indentation of turning up need turn over according to the use shakes the lid and rolls over carries out the adaptability adjustment in 1/3~2/3 within range of honeycomb piece cigarette case cardboard thickness, and the degree of depth of the introversion indentation 302 of inner box 100 and outer container 400 and the indentation of bending outward also can carry out the adaptability adjustment according to the angle of buckling of the cardboard for the honeycomb case in the recovery process, the enstrophe indentation of inner box and outer container, turn up, introversion indentation and the indentation of bending outward can also press the shaping of honeycomb cardboard through a line pair, perhaps meet the line shaping.
