On February 15, 2006, the State Intellectual Property Office published an invention patent applied by General Tobacco Group Co., Ltd. – Equipment for eliminating static electricity during the cigarette packaging production process and methods for eliminating static electricity. The invention discloses a static elimination device and a method thereof in a cigarette packaging production process. The utility model solves the problem that the existing plastic transparent paper material is difficult to eliminate static electricity, has poor adaptability, can not be adjusted at any time according to the static electrode chargeability thereof, and is easy to damage the paper and cause personal injury. The utility model has the advantages of simple structure, convenient installation, and automatic judgment of static electricity. The polarity of the charge, the adjustment of neutralizing charge, and the safe and rapid elimination of static electricity, etc., are structured as follows: it has an electrostatic generator mounted on a conveyor belt, and an electrostatic detector I is installed on the conveyor belt in front of the electrostatic generator, and the static electricity is generated. An electrostatic detector II is installed on the belt behind the device, and the two electrostatic detectors are connected with the electrostatic generator to form a charge detection and feedback loop. They send the detected polarity and voltage of the electrostatic charge into the electrostatic generator, and generate polarity therefrom. The opposite electrostatic charge is then blown onto the transparent paper material by a fan, neutralizing the static electricity on it, and the result of the detection is then fed back to the electrostatic emitter.
