Abstract
Description
Technical Field
[0001] The utility model relates to a card packaging machine and a folding device used therein. Background Art
[0002] The card packing machine is a packaging device that packs a group of cans or bottles with cardboard. The formed cardboard package will form folded corners at the four upper corners to strengthen the position fixation of the cans or bottles in the cardboard package. For this, easy folding lines will be pre-made on the cardboard blank sheet, which include an oblique folding line corresponding to the top of the cardboard package to form a downward folding of the corner, a vertical folding line corresponding to the side of the cardboard package to form an inward folding of the upper part of the side, and a middle folding line located between the oblique folding line and the vertical folding line. In production, the first folding mechanism first folds the corresponding part of the cardboard blank sheet downward according to the oblique folding line, and then the second folding mechanism folds the corresponding part of the cardboard blank sheet inward according to the vertical folding line and the middle folding line to form the above-mentioned folded corners. The cardboard package can be regarded as a square three-dimensional shape, so there are four upper corners that need to be folded as above, so the second folding mechanism will have 4 second folding parts. At present, in cardboard packaging machines, the second folding mechanism in the folding device can only adapt to one cardboard package size. If the size of the cardboard package changes (for example, cans are replaced with bottles, or cans of different sizes are replaced, or bottles of different sizes are replaced), even if the first folding mechanism can adapt to different length changes, the folding device needs to be removed and replaced with a new second folding mechanism.
