1. A method for manufacturing and packaging a special-shaped cigarette, comprising the following steps:
1) designing inner packaging case paper capable of being folded into a special-shaped cigarette accommodating cavity;
2) folding the inner packaging case paper to form the special-shaped cigarette accommodating cavity;
3) filling an interior of the special-shaped cigarette accommodating cavity with an ordinary cigarette; and
4) shelving for a certain period of time, so that a cross section of the ordinary cigarette changes from a circle to a special shape under fixing and extruding effects of the special-shaped cigarette accommodating cavity and the ordinary cigarette is accommodated in the special-shaped cigarette accommodating cavity, wherein
a diameter of an inscribed circle of the special-shaped cigarette accommodating cavity is less than a diameter of the ordinary cigarette, and a material of the inner packaging case paper is a paperboard or a food grade polyvinyl chloride (PVC) sheet;
the special-shaped cigarette is a square cigarette with a cross section being a square;
wherein inner packaging case paper of the square cigarette comprises a square-cigarette filling and compressing positioning sleeve, a square-cigarette middle layer spacing sleeve, and a square-cigarette partition board;
the square-cigarette filling and compressing positioning sleeve comprises a square-cigarette first folding baffle, a square-cigarette second folding baffle, a square-cigarette third folding baffle, a square-cigarette fourth folding baffle, a square-cigarette fifth folding baffle, and a square-cigarette sixth folding baffle, and the square-cigarette filling and compressing positioning sleeve is capable of being folded into a first cuboid; and the square-cigarette second folding baffle, the square-cigarette third folding baffle, the square-cigarette fourth folding baffle, and the square-cigarette sixth folding baffle are sequentially connected with four edges of the square-cigarette first folding baffle to serve as four side surfaces of the first cuboid, the square-cigarette first folding baffle serves as a bottom surface of the first cuboid, and the square-cigarette fifth folding baffle serves as a top surface of the first cuboid;
the square-cigarette third folding baffle and the square-cigarette second folding baffle have the same size and shape, and located on left and right sides of the square-cigarette first folding baffle respectively, two square-cigarette first folding lug are connected to one end of the square-cigarette second folding baffle far away from the square-cigarette first folding baffle and one end of the square-cigarette third folding baffle far away from the square-cigarette first folding baffle respectively, and one end of each square-cigarette first folding lug far away from the square-cigarette first folding baffle has a square-cigarette first pin;
the square-cigarette fourth folding baffle and the square-cigarette sixth folding baffle are located on an upper side and a lower side of the square-cigarette first folding baffle respectively, one end of the square-cigarette fourth folding baffle far away from the square-cigarette first folding baffle is connected with the square-cigarette fifth folding baffle, and the square-cigarette fifth folding baffle is provided with a square-cigarette first pre-notch corresponding to the square-cigarette first pins;
a square-cigarette second folding lug and a square-cigarette third folding lug are sequentially connected to one end of the square-cigarette sixth folding baffle far away from the square-cigarette first folding baffle, a connection part of the square-cigarette sixth folding baffle and the square-cigarette second folding lug is provided with a square-cigarette pull buckle, and the square-cigarette second folding lug and the square-cigarette third folding lug are capable of being inserted into the first cuboid from the top surface of the first cuboid;
the square-cigarette second folding lug and the square-cigarette third folding lug are capable of being pulled out of the first cuboid by pulling the square-cigarette pull buckle by hand;
the square-cigarette middle layer spacing sleeve comprises a square-cigarette seventh folding baffle, a square-cigarette eighth folding baffle, and a square-cigarette ninth folding baffle, and the square-cigarette middle layer spacing sleeve is capable of being folded into a second cuboid with an opening in a side surface; and the square-cigarette seventh folding baffle serves as a top surface of the second cuboid, the square-cigarette eighth folding baffle serves as a bottom surface of the second cuboid, and the square-cigarette seventh folding baffle is connected with the square-cigarette eighth folding baffle through the square-cigarette ninth folding baffle;
the square-cigarette eighth folding baffle has a square second pre-notch, left and right sides of the square-cigarette eighth folding baffle extend outwards to have a square tenth folding baffle, one end of the square tenth folding baffle far away from the square-cigarette eighth folding baffle has a square second pin, the square tenth folding baffle is provided with a crease line, by overturning and folding along the crease line, the square second pin is capable of being inserted into the square second pre-notch, and the square tenth folding baffle forms a third cuboid with a cavity structure on the left and right sides of the square eighth folding baffle;
the second cuboid is inserted into the first cuboid, a top and bottom of the second cuboid form a fourth cuboid cavity with a top and bottom of the first cuboid respectively, and an inner cavity of the second cuboid and the fourth cuboid cavity limit shapes and sizes of the cigarettes so as to generate fixing and extruding effects on the cigarettes;
the square-cigarette partition board comprises a square plate main body and a plurality of square-cigarette vertical spacers perpendicular to the square plate main body and erected on the square plate main body, and each square-cigarette vertical spacer is inserted into a gap between the adjacent cigarettes so as to generate the fixing and extruding effects on the cigarettes on two sides of the square-cigarette vertical spacer; and
circular cigarettes in the second cuboid and the fourth cuboid are changed into square cigarettes under three kinds of fixing and extruding of the square-cigarette filling and compressing positioning sleeve, the square-cigarette middle layer spacing sleeve, and the square-cigarette partition board.
