The utility model discloses at the film at towed in-process, earlier through positive charge dust collector, detach the dust of negative charge ion under faster air flow rate, then through negative charge dust collector, detach the dust of positive charge ion under faster air flow rate, electrically neutral's dust is at the film traction in-process, because electrically neutral's the reason, and is weaker with the film adsorption affinity, gets rid of in the lump under faster air flow speed.
Description
Technical Field
The utility model relates to a film dust removal technical field, especially a non-contact film dust collector.
Background
At present, the film dust removal device is mainly divided into two main types of contact type dust removal and non-contact type dust removal, wherein the contact type dust removal has dust removal modes such as a dust sticking roller, a dust sticking adhesive tape, a brush, a cleaning towel and the like; the non-contact dust removal is to neutralize the electrical property of dust by ionic wind, reduce the adsorptivity of the dust and a film and then remove the dust in a mode of carrying the dust away by the wind. The contact type dust removal not only takes away dust on the surface of the film, but also can cause certain damage to the surface of the film, especially the optical film, and the use of the contact type dust removal can affect the optical performance of the film to a certain extent. The existing non-contact dust removal device is used as a cyclone dust removal device, and the ion wind is used in the dust removal process, and because the ion wind carries a large amount of positive and negative charge ions, the charges on the surface of the film can be removed to a certain extent while the charges of dust are removed, so that the use effect of the film with the static requirement is greatly reduced, and even the film is ineffective.
Disclosure of Invention
To the problem that exists among the prior art, the utility model aims to provide a non-contact film dust collector.
In order to solve the above problems, the utility model adopts the following technical proposal.
The utility model provides a non-contact film dust collector, includes at least two sets of dust removal mechanisms of fan, dust removal mechanism sets up the both sides at the film respectively, dust removal mechanism includes positive charge dust collector and negative charge dust collector, the fan sets up in one side of positive charge dust collector, negative charge dust collector in order to be used for producing the wind pressure, alleviate the adsorption affinity of dust and film, makes electrified dust break away from the film surface under the effect of electric field, removes to positive charge dust collector, negative charge dust collector direction.
As a further improvement, the positive charge dust collector includes first metal sheet and the direct current negative high voltage generator who is connected with first metal sheet, the negative charge dust collector includes second metal sheet and the direct current positive high voltage generator who is connected with the second metal sheet, first metal sheet, second metal sheet are close to the film.
As a further improvement of the utility model, the direct current positive high voltage generator generates a positive voltage of 15Kv-30Kv, and the direct current negative high voltage generator generates a negative voltage of 15Kv-30 Kv.
The beneficial effects of the utility model
Compared with the prior art, the utility model has the advantages of:
the utility model discloses at the film at towed in-process, earlier through positive charge dust collector, detach the dust of negative charge ion under faster air flow rate, then through negative charge dust collector, detach the dust of positive charge ion under faster air flow rate, electrically neutral's dust is at the film traction in-process, because electrically neutral's the reason, and is weaker with the film adsorption affinity, gets rid of in the lump under faster air flow speed. In the positive charge dust removal device and the negative charge dust removal device, positive charges and negative charges do not contact the film, static electricity on the surface of the film is not attenuated, and the surface of the film is not damaged.
