Embodiment Construction

[0016] Such as figure 1 , 2 , 3, in the inner hole of the tubular outer roller body 2, the inner roller body 4 is matched, the inner and outer roller bodies can rotate relatively, and the outer roller body is provided with a long slot hole 9, and the dotted line knife 3 passes through the fixed The elongated fixing plate on the inner roller body is fixedly installed on the inner roller body, and stretches out the outer roller body through the slotted hole, and the cutting knife 11 is fixedly installed on the outer roller body by the U-shaped strip fixed on the outer roller body. When it is necessary to adjust the distance between the cutting knife and the dotted line knife, loosen the fixing screw 5 used as a positioning device, rotate the inner roller body, and make the arc length between the cutting knife and the dotted line knife reach the required length, and then go up Tighten the screws to make the relative positioning of the outer roller body and the inner roller body....

Abstract

The invention relates to a packaging film cutting device in a packaging machine. A film cutting roll of the packaging film cutting device comprises a roll, a cut-off knife and a dotted-line knife, and the cut-off knife and the dotted-line knife are fixedly mounted on the roll. The packaging film cutting device is characterized in that the roll comprises a tubular outer roll and an inner roll fittingly nested inside the outer roll, the inner roll and the outer roll are fixed relatively by a positioning device, a slotted hole is arranged on the outer roll, the dotted-line knife or the cut-off knife can extend out of the slotted hole, and the dotted-line knife and the cut-off knife are respectively fixedly mounted on the inner roll and the outer roll via knife holders. The packaging film cutting device has the advantages that the roll is multipurpose, a packaging film can be continuously cut off and conveyed, and the like. Besides, distances can be adjusted conveniently, so that the requirement on variation of the length of the packaging film within a certain range can be met, and an existing intermittent packaging production line can be changed into a continuous packaging production line.

Description

Technical field [0001] The invention relates to a film cutting device for a packaging film in a packaging machine. Background technique [0002] On the household paper packaging line, it is necessary to cut the packaging plastic film and cut out a dotted tear opening. At the same time, the length of the packaging plastic film and the position of the tear opening must be adjusted according to different specifications. The existing plastic film cutting device for packaging is equipped with a fixed knife on the frame. During the process, the color mark sensor on the plastic film is used to control the movement and stop of the plastic film. When cutting and cutting out the dotted tear opening, the plastic film must stop moving. At present, this intermittent cutting method limits the packaging speed and efficiency of the entire packaging equipment. At the same time, it is necessary to print color codes on the packaging plastic film according to the packaging length, which increa...
