(a) Field of Industrial Application This invention relates to a self-discharge type static eliminator that prevents static eliminator fibers from falling off from a metal plate of the static eliminator. (b) Prior art As shown in Fig. 1, a conventional self-discharge type static eliminator has a static eliminating fiber group (a collection of two or more fibers having a static eliminating effect) between a metal plate 1 and a metal plate 2. Since it is made by putting static eliminating fiber group (3) and adhesive 4, applying pressure from the outside of the metal plate and drying it, there is a gap between metal plate 1 and metal plate 2 equal to the thickness of the static eliminating fiber group. Since this gap is a space, it is easy for the adhesive 4 to enter there, so most of the adhesive gathers here, and it is difficult to seep into the inside of the important group of static-eliminating fibers, so it is possible to bond up to the static-eliminating fibers that are inside the static-eliminating fibers. First, the static eliminating fibers may fall out and enter the high-voltage application section in the electronic copying machine, causing a short circuit and causing the electronic copying machine to lose its functionality. Also, when the flat part of the static eliminator is curved and attached to the outer periphery of the pipe outlet, the bonded positions of the inner metal plate and the outer metal plate shift, and the bond between the static eliminator fibers separates and the metal plate More detached. (C) Problems to be Solved by the Invention The purpose of the present invention is to prevent a group of static eliminating fibers and some of the static eliminating fibers in the group of static eliminating fibers from falling off from a metal plate. (d) Means for Solving Problems This invention, as shown in FIG.
Cloths, leather, etc. are written as flexible boards on the statement)
A group of static eliminating fibers 3 and an adhesive 4 are placed between the flexible plate 5 and the flexible plate 5, and pressure is applied from the outer surface of the flexible plate 5 to bond them. (E) Function Since pressure is applied from the outer surface of the flexible plate 5, there is no gap between the flexible plate 5 and the metal plate 1 as shown in FIG. As this happens, the adhesive 4 is strongly permeated from the periphery to the inside of the static eliminating fiber group 3, so that the portion of the static eliminating fiber group 3 between the flexible plate 5 and the metal plate 1 is fixed as one piece, so that the static eliminating fiber group 3 is fixed. Since the static eliminating fibers in the static eliminating fiber group do not come off or fall out, short circuit accidents such as those described above do not occur. 50 mm, length 50 to 1000 mm, etc. were used. Flexible board 5 Thin metal plate made of aluminum foil, copper foil, etc. with a thickness of 30~
150 μm, width 9 to 49 mm, length 50 to 1000 mm, etc. were used. Synthetic resin with a thickness of 100 to 1000 μm, width and length the same as a thin metal plate Rubber plate, 20 to 1000 μm in thickness Paper, 50 to 500 μm in thickness Cloth, cotton, linen, silk, synthetic fiber, etc. in thickness 50 to 500 μm Leather/snail skin thickness 50 to 500 μm Carbon fiber as a static neutralizing fiber group Stainless steel fiber (1 bundle of 6,000 fibers 7 μm thick) Nicalon fiber (1 bundle of 100 fibers 12 μm thick) Amorphous fiber (1 bundle of 500 fibers 9 μm thick) Thickness One bundle or more of 20 μm x 49 wires are attached to metal plate 1 at intervals of 1 to 20 mm. The mounting shape was designed to match the flat surface and the outer surface of a pipe with an outer diameter of 50 mm. (g) Effects of the Invention As explained above, this invention provides that when the outer surface of the flexible plate 5 is pressed by a rubber roller or an iron roller, the flexible plate 5 is separated from the flexible plate 5 of the static elimination fiber group and the metal plate 1.
Adhesive 4 is press-fitted into the static eliminating fiber group 5 and hardens at the same time as surrounding the portion between the two. Since the flexible plate 5 and the metal plate 1 are closely bonded to each other by the adhesive 4 in the areas where there are no static eliminating fibers, the static eliminating fiber group 3 and some of the static eliminating fibers in the static eliminating fiber group do not fall out from the metal plate 1. Further, even if the flat part of the metal plate of the static eliminator of the present invention is bent and fixed to the outer periphery of the pipe outlet, the static eliminator fiber group remains in close contact with the metal plate without change. In the areas where there is no static eliminating fiber group, the flexible plates are in close contact with each other, with a slight expansion and contraction (H) Experimental results: When this static eliminator is used on a flat surface, 200,000 sheets of B4 copy paper are passed through as the object to be neutralized. This static eliminator was bent and fixed to fit the outer circumference of 50 mm, and water was passed through the pipe for 100 hours, and then inspected, but no single static eliminator fiber fell out. There was no drop.
