To be placed in corresponding carton mould after the first U-shaped carton base and the mutual vertical pile of the second U-shaped carton base, hot pressing 6min-8min is carried out under temperature is 65 DEG C of-68 DEG C of conditions, after being cooled to room temperature, by connecting axle through the connecting ring on the second U-shaped carton base and case lid base, obtain carton.
Preferably, in the preparation method of described carton, a described first rectangular long end end is provided with one first sticking part, and the end on another long limit is provided with the second sticking part,
Preferably, in the preparation method of described carton, the length of described first sticking part and described second sticking part equals the height of carton to be produced.
Preferably, in the preparation method of described carton, described second rectangular width is equal with described first rectangle width.
Preferably, in the preparation method of described carton, described case lid portion and described connecting portion overlap and bond together.
The invention provides a kind of preparation method of carton, it comprises paperboard and carton making.Adopt terylene silk thread that this glass fibre plain prepreg, steel wire and elementary corrugated board are stitched into paperboard blank; The elementary corrugated board of another block is adhered to afterwards, obtained cardboard in the one side being provided with steel wire; The cardboard made is carried out being cut into the first rectangle according to preliminary dimension, and puts into corresponding cardboard mould, after carrying out Hot-press cooling to room temperature, obtain the first U-shaped carton base; The cardboard made is cut into the second rectangle according to the size of carton to be produced, puts into corresponding cardboard mould and carry out hot pressing, after being cooled to room temperature, obtain the second U-shaped carton base; The cardboard made is cut into a rectangle box cover body according to the size of carton to be produced, and the cardboard mould putting into correspondence carries out Hot-press cooling to room temperature and obtains case lid base; After being placed on after the first U-shaped carton base and the mutual vertical pile of the second U-shaped carton base and carrying out Hot-press cooling to room temperature in corresponding carton mould, by connecting axle through the connecting ring on the second U-shaped carton base and case lid base, obtain carton.Adopt the carton that method of the present invention makes, with the addition of steel wire and glass fibre in common cardboard, and adopt heat pressing process to obtain, make to connect closely between each several part, and anti-pressure ability is strong, and has very high mechanical property, service life is strong.
Part is embodied by explanation below by other advantage of the present invention, target and feature, part also will by research and practice of the present invention by those skilled in the art is understood.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
