AUTOMATIC PACKAGING MACHINE

PROBLEM TO BE SOLVED: To provide an automatic packaging machine which can easily correct a cutting angle of a cutter device to a packaging material in a simple constitution so that an occurrence of an oblique deviation of a cut surface and a perforation in a package is prevented to get the high quality package.SOLUTION: An automatic packaging machine 1 comprises: a molding chute 3 in which a long packaging material 2 is folded into two in a longer direction; a vertical seal device 4 and a lateral seal device 5 in which an object to be packed supplied from the molding chute 3 is hermetically sealed within the packaging material 2 folded into two; and a cutter device 6 in which the packaging material 2 having the object to be packed hermetically sealed is cut at every predetermined isolation distance by a rotary blade body 61 so that one or more continuous packages are obtained. The cutter device 6 is swung around an engagement part E between a rotary blade body drive gear 66 connected to a rotary drive shaft 63 of the rotary blade body 61 and a power transmission gear 16 which is disposed in the machine body and to which power of a drive motor 12 is transmitted, and is mounted to be capable of adjusting a cutting angle to the packaging material 2.
