The utility model relates to a static adsorption apparatus constructs, including pay off rack that is equipped with the drawing drum and the take -up stand who is equipped with the take -up reel, its characterized in that: pay off rack and take -up stand between be equipped with two insulation support, two independent insulating coating pipes are installed on each self -corresponding insulation support, and the insulating coating is intraductal is equipped with sleeve pipe in inflexible, the sleeve pipe is equipped with the hole that quiet electric wire freely passes through in and, the interior terminal surface of two insulating coatings pipe lies in the terminal surface of casting the piece roller and does not meet with the terminal surface of casting the piece roller, the outer end face that two insulating coatings were managed is corresponding to one side of drawing drum and one side of take -up reel. The utility model is simple and reasonable in structure, quiet electric wire to not casting the regional department of piece roller protects, can solve quiet electric wire and split the problem at removal process interrupt.
