The video acquisition mechanism 5 is fixed at the outlet side wall of the darkroom 4 and is used for acquiring light images in the darkroom 4.

The air exhaust mechanism 6 is communicated with the outlet of the darkroom 4. Through the action of the air exhaust mechanism 6, air is extracted from the surface of the BOPP film 100, and dust particles adsorbed on the surface of the film body sequentially enter the dust hood and the darkroom along with the air flow. The outlet end of the air exhaust mechanism 6 is provided with a filter screen for collecting dust particles.

The visual terminal 7 is in communication connection with the video acquisition mechanism 5 and is used for displaying images acquired by the video acquisition mechanism 5.

The shell 8 is provided with an opening at the bottom for integrating and fixing the static electricity removing mechanism 1 and the dust hood 2, and the top box body 81 is internally provided with the light source 3, the darkroom 4, the video acquisition mechanism 5 and the air exhaust mechanism 6.

After the static removing mechanism removes the static electricity on the surface of the BOPP film, the adsorption force of the film surface on dust particles is reduced. After the film surface enters the lower part of the dust collection cover, dust at the film surface can enter the dark room along with the airflow formed by the air pumping mechanism. The dust particles in the airflow form colloid, so that the light projected into the darkroom by the light source generates the Tyndall effect to form a light column. The video acquisition mechanism acquires the light beam image and transmits the light beam image to a visual terminal arranged outside. The operator can judge the amount of the sucked dust particles according to the size of the light beam.
