Description

Technical Field

[0001] The utility model belongs to the technical field of film static elimination, and in particular relates to a tool for eliminating static electricity on the surface of a film. Background Art

[0002] When the film is rolled up at high speed, the friction between the film surface and the rubber roller surface generates static electricity, which causes many problems such as uneven film rolling and inconsistent film surface rolling hardness. During the slitting process, a lot of film width is wasted at the edge during slitting, resulting in low product yield.

[0003] On the original equipment, static electricity is eliminated by installing electrostatic carbon brushes on both sides. However, the carbon brushes have poor conductivity and as the years of use increase, the conductivity of the carbon brushes decreases, and the static electricity problem on the membrane surface becomes more and more serious.
