Disclosed is a cutting device for a plastic bag manufacturing device. According to the present invention, the cutting device for a plastic bag manufacturing device comprises: a heat treatment cutting board (10) to which a high temperature is applied and heat is given to a plastic film; and a cutting unit (14) installed on the heat treatment cutting board (10) to be vertically elevated and lowered by an elevation driving unit (12). The cutting unit (14) comprises: a cutting knife (140) whose blade (1400) heads toward the floor and which has a pair of first guide rods (1402) protruding outside while being spaced at a first interval on the side surfaces of the front and back and has a bearing (1404) which is inserted into an end of the first guide rods (1402); a frame body (142) which has a staple shape that the opened bottom surface heads toward the floor and which accommodates the cutting knife (140) in an open space; and a film guide unit (144) which comprises a guide plate (1444) for connecting the end units of the second guide rods (1440) on both sides to be combined to be able to be elevated and lowered along the second guide rods (1440). According to the present invention, the cutting device for a plastic bag manufacturing device is realized to simultaneously conduct vertical cutting and horizontal slicing, and when manufacturing a plastic bag, quality defect due to a defect in cutting is prevented, and the cutting is easily performed. |
