Abstract

The utility model discloses a static elimination device of a paper web, comprising a transmission roller for guiding the paper web, at least one static export brush and an export circuit, wherein the static export brush is located at one side of the transmission paper web and in contact with the circumferential side surface of the transmission roller; and one end of the export circuit is connected in series with the static export brush while the other end thereof is grounded. After the static elimination device of the paper web is arranged on the papermaking equipment, the static on the surface of the paper web is effectively released, thereby reducing the interference and the loss of the electronic circuit and the paper machine electric equipment, improving the production efficiency and the product quality, and achieving the purpose of safe production.

Description

The paper web static eraser

Technical field

The utility model discloses a kind of paper web static eraser, divides by International Patent Classification (IPC) (IPC) to belong to paper making equipment class manufacturing technology field, especially relates to its surface electrostatic cancellation element when paper web transmits in the paper-making process.

Background technology

In paper-making process, last group drying cylinder is to existing stronger static between the reeling end, and static produces electronic circuit easily and disturbs, and causes the instantaneous change of current potential; Static discharge can cause the fault of electronic equipment, punctures integrated circuit and accurate electronic component, causes component ageing; Static can influence operating personnel's physical and mental health simultaneously, causes operating personnel's psychological pressure, and operating efficiency descends.And mainboard and circuit that serious static can burning apparatus cause damage to the paper machine electrical equipment; It also influences paper quality, and can adsorb dust, paper is cohered, collection causes obstacle, can't autofeed during paper or frequently two opening occur in finished product workshop section cut paper and reason, empty opening, the collection disorder, adverse consequences such as loss increase, not only reduce production efficiency but also influence product quality, if the static that production process produces is not eliminated, static discharge phenomenon generation electric spark to a certain degree will take place when running up to, villus fiber, dust-free paper belongs to inflammable thing the danger that causes fire, safety and production in serious threat, increases cost certainly and influences existing paper technology equipment and professional static abatement apparatus is installed, inconvenient operation.

The generation of static is that fiber is because surface ratio resistance is big in paper-making process, poorly conductive, between fiber and the equipment, fiber can not scatter because of friction generation static is accumulated in fiber surface between the fiber, form certain electrostatic pressure thereby produce papermaking static, the inventor creates the elimination electrostatic equipment of simple and easy practicality, so proposition of the present utility model is just arranged.

Summary of the invention

At the harm of existing papermaking static, the utility model provides a kind of paper web static eraser of rational in infrastructure, simple and easy practicality.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of paper web static eraser comprises transfer roller, the static derivation brush that guides paper web and derives circuit, wherein,

Static is derived brush, at least one, its be positioned at the transmission paper web a side and with all contacts side surfaces of transfer roller;

Derive circuit, the one end is series at static and derives brush, derives circuit and holds ground connection in addition.

Further, it is two graphite carbon brush that described static is derived brush, and above-mentioned two graphite carbon brush are individually fixed on the carbon brush holder, and carbon brush holder is connected and fixed on angle steel, and angle steel end in addition is fixed on the papermaking frame, and the papermaking frame is by conductor wire ground connection.

Further, described derivation circuit is to be composed in series by carbon brush holder, angle steel, papermaking frame and conductor wire.

Carbon brush holder in the utility model and papermaking frame all are that materials such as metal material such as iron and steel are made, and have conducting function, and above-mentioned derivation circuit also can be by direct ground connection behind the conductor wire connection carbon brush.Ground connection is the way of the simplest elimination static, promptly metallic conductor is connected with the earth, makes it and the earth equipotential, and electric charge just discharges through the earth.

After the utility model paper web static eraser is installed on the paper making equipment, paper surface static is effectively discharged, interference and damage have been reduced to electronic circuit and paper machine electrical equipment, production efficiency and product quality have been improved, reach safety in production, also saved the expense of purchasing professional static eraser simultaneously.

Description of drawings

Fig. 1 is the utility model structural representation;

Each component names among the figure:

1, transfer roller,

2, paper web,

3, graphite carbon brush,

4, carbon brush holder,

5, angle steel fixed mount,

6, papermaking frame,

7, spring bearing.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: see also Fig. 1, a kind of paper web static eraser comprises that the transfer roller 1 that guides paper web, static derives brush and derive circuit, and static is derived at least one on brush, its be positioned at the side that transmits paper web 2 and with all contacts side surfaces of transfer roller 1;

See also Fig. 1, it is two graphite carbon brush 3 that static is derived brush, and above-mentioned two graphite carbon brush 3 are individually fixed on the carbon brush holder 4, and carbon brush holder 4 is connected and fixed on angle steel or angle steel fixed mount 5, angle steel or angle steel fixed mount bottom are fixed on papermaking frame 6, and papermaking frame 6 is by conductor wire ground connection.

Derive circuit and be made up of carbon brush holder 4, angle steel fixed mount 5, papermaking frame 6 and conductor wire, above-mentioned derivation circuit also can be by direct ground connection behind the conductor wire connection carbon brush.

In the normal paper production process, last group drying cylinder almost is to insulate to the camber roller between the reeling end or spring paper carrying roll roll body and rack earth after tested, resistance reaches 20 megaohms, main cause is that ball surface formation one deck oil film in the title bearing 7 is propped up at camber roller or spring paper carrying roll two ends when rotating at a high speed, and oil film insulate, therefore just form insulation between roll body and the rack earth, paper surface static can't discharge.

The concrete way of the utility model be with two carbon brush holders be fixed on the angle steel, angle steel is fixed on the frame again, 2 graphite carbon brush are installed in the carbon brush holder, carbon brush and transmission roll surface edge joint touch, roll body just forms one with frame and links to each other with the earth like this, paper web 2 during through roll surfaces the electric charge on surface discharge through carbon brush-carbon brush holder-angle steel-frame-the earth.

The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
