During the composite production process, the prepreg 4 passes through the device to evenly eliminate the static ions on the surface of the prepreg 4. At the same time, the plasma static elimination gun 2 can generate a large number of air masses with positive and negative charges, which are blown away by the ion wind. The air blown out can neutralize the charge on the object. When the charge on the surface of the object is positive, it will attract the negative charge in the airflow, so that the static electricity on the surface of the object is neutralized, achieving the purpose of eliminating static electricity. The high-speed compressed air can also blow away the stubborn dust on the object. Therefore, the utility model has a simple structure, small size, light weight, easy installation and maintenance, and does not produce harmful rays and does not pollute the environment.
