Abstract

A dust removing device used in film production comprises two tangent compression rolling wheels opposite in rolling direction and one recovery rolling wheel. The two compression rolling wheels enable two films to be combined and compressed together. Interlamination paper is wound on the recovery rolling wheel, located between the two films and drawn out of the position between the two films under the driving of the recovery rolling wheel. Static eliminating fans are arranged at the positions of the two films before the two compression rolling wheels perform compression, and only one static eliminating fan is arranged at the compressed positions of the two films after the two compression rolling wheels perform the compression. The dust removing device enables the films not to easily suck dust by removing static on the films and further achieves the dust removing purpose.

Description

Dust cleaning apparatus in a kind of film production

Technical field

The utility model relates to the membrane switch technology field, especially relates to a kind of dust cleaning apparatus in the thin-film process of producing thin film switch.

Background technology

Thin film switch claims the soft-touch type keyboard again, the integral sealing structure that adopts the plane multiple layer combination to form, be light harvesting, the mechanical, electrical integrated a kind of new electronic component that key switch, panel, mark, symbol demonstration and liner plate are sealed, it is the change of electronic product surface structure essence, it can replace the button of conventional discrete component, more reliably the task of executive operating system.

Have thin film switch excellent waterproof, dustproof, grease proofing, anti-pernicious gas corrode, stable and reliable for performance, in light weight, volume is little, the life-span is long, the dress connection conveniently, panel can wash and character is injury-free, rich color, advantage such as elegant in appearance.The thin film switch panel is matrix with rigidity or flexible circuit board, has installed feel or has not had the feel button, constitutes coated with the plastics that are printed with the polychromy pattern (polycarbonate, polyester PET etc.) film face-plate again.

Because films such as PET have static, the work in-process friction can produce small static, and the tiny dust in the absorbed air impacts product quality easily, therefore needs to solve the easily problem of sticking dust of film.

The utility model content

At the problems referred to above that prior art exists, the applicant provides a kind of dust cleaning apparatus of film production.This device is by removing the static on the film, thereby makes film be not easy to attract dust, and then reaches the dedusting purpose.

The technical solution of the utility model is as follows:

Dust cleaning apparatus in a kind of film production comprises two pinch rollers tangent, that rotating direction is opposite and an independent recovery roller; Described two pinch rollers with two kinds of film combined pressures together; Paper between winding layer on the described recovery roller; Described interlayer paper is extracted out between two kinds of films under the drive of reclaiming roller between two kinds of films;

Described two positions of pinch rollers before two kinds of film combined pressures respectively arrange one respectively and destatic blower fan, and described two positions of pinch rollers after two kinds of film combined pressures only arrange one and destatic blower fan.

The utility model beneficial technical effects is:

This device is by destaticing ion blower, in and the static on PET material surface, thereby stop the Electrostatic Absorption of tiny dust, reduce the intrusion of dust, improve product quality.

Description of drawings

Fig. 1 is the schematic diagram that arranges of this dust cleaning apparatus.

Embodiment

Below in conjunction with accompanying drawing, the utility model is specifically described.

This dust cleaning apparatus is to remove in the step of interlayer paper to come into operation in film production.Its concrete setting as shown in Figure 1.Two kinds of films 1 forwards move by two pinch rollers 2 and pinch rollers 3 respectively, and combined pressure together; Interlayer paper is rolled into volume from extracting out between two kinds of films 1 by reclaiming roller 4 drives.

Reclaiming roller 4 is autorotation rollers, and its power resources are that automatic tension is adjusted motor 7, and the model that can select FUJISHOKO company in the enforcement for use is the motor of MTB-200 95444.Automatic tension is adjusted motor 7 can adjust the rotating speed that reclaims roller 4 automatically, makes the interlayer paper roll build up the volume that has certain tightness, is applicable to suitability for industrialized production.

Before the interlayer paper roll is adjusted motor 7 to automatic tension; reverse side binding dust roller 5 is set below interlayer paper; front binding dust roller 6 is set above interlayer paper; these two binding dust rollers can siphon away the dust on the interlayer paper; make the interlayer paper cleaning that is rolled into volume clean, can be directly used in alternative diaphragm.

In the front and back of two pinch rollers Destaticizing device 8 is set, wherein the place ahead of pinch rollers 2 and pinch rollers 3 arranges a Destaticizing device 8 respectively, its effect is static and the dust of removing respectively before two kinds of film combined pressures separately, pinch rollers 2 and pinch rollers 3 rears only arrange a Destaticizing device 8, are to becoming as a whole film to carry out dedusting after the combined pressure.Destaticizing device 8 can be selected the product of the quiet Electricity mood of シ シ De Co., Ltd. for use, and model is BICS type 150.

After two kinds of film combined pressures, through after the Destaticizing device 8, its surperficial static is removed, and the probability that therefore adsorbs dust reduces greatly.In order to guarantee the definitely pure of film, before film was about to come into operation, the below arranged a film binding dust roller 9 respectively thereon, the dust of only a few on the film is removed, thereby guaranteed the high-quality of film.

Claims (1)

1. the dust cleaning apparatus in the film production is characterized in that comprising two pinch rollers tangent, that rotating direction is opposite and an independent recovery roller; Described two pinch rollers with two kinds of film combined pressures together; Paper between winding layer on the described recovery roller; Described interlayer paper is extracted out between two kinds of films under the drive of reclaiming roller between two kinds of films;

Described two positions of pinch rollers before two kinds of film combined pressures respectively arrange one respectively and destatic blower fan, and described two positions of pinch rollers after two kinds of film combined pressures only arrange one and destatic blower fan.
