Description

Technical Field

[0001] The utility model relates to the technical field of cigarette-making equipment, in particular to a transparent paper drawstring cutting device. Background Technique

[0002] The FOCKE401 transparent paper packaging machine is mainly used to complete the supply, cutting, folding, heat sealing, and forming of the transparent paper and drawstring for small box cigarette packs, and finally convey the qualified cigarette packs to the next process. Among them, the transparent paper and drawstring are respectively supplied by coils. The drawstring is adhered to the corresponding position of the transparent paper and enters the cutting device together after being bonded. First, a pair of traction rollers pull the transparent paper and drawstring into the drawstring cutting device, and a U-shaped opening is cut out by the cutting device to facilitate the subsequent folding of the transparent paper drawstring. Then, the traction rollers continue to convey the transparent paper and drawstring with the U-shaped opening cut out downward. During the conveyance, the transparent paper and drawstring are cut off by a transparent paper cutter to become single sheets of transparent paper of a fixed length. Finally, it is conveyed to the reciprocating sleeve opening of the cigarette pack under the adsorption of a vacuum belt. The single sheet of transparent paper merges with the cigarette pack and is brought into the folding turret by the cigarette pack to complete the subsequent folding, heat sealing, and forming actions.

[0003] At present, the drawstring cutting device of the FOCKE401 transparent paper packaging machine mainly obtains power from a cutting tool box. Through the cutting tool pad roller on the pad roller shaft and the U-shaped cutting tool on the cutting tool shaft located below, the U-shaped cutting tool contacts and presses against the cutting tool pad roller driven by the rotation of the cutting tool shaft to complete the cutting of the U-shaped opening of the transparent paper drawstring. However, both the pad roller shaft and the cutting tool shaft are single-arm shafts led out from the tool box. The inner side of the shaft is supported by the box body, while the outer side of the shaft is a suspended design without support. In actual use, the suspended structures of the cutting tool shaft and the pad roller shaft have the problem of large vibration frequency, resulting in jitter during the rotation of the cutting tool shaft, causing serious unilateral wear of the U-shaped cutting tool and easy wear of the cutting tool pad roller, affecting the cutting and conveyance of the transparent paper drawstring, resulting in poor forming of the transparent paper cigarette pack and generating quality defects.
