The utility model discloses a non-contact type film dust removal device, which comprises at least two groups of dust removal mechanisms of a fan. The fan is arranged on one side of the positive charge dust removal device and the negative charge dust removal device to generate wind pressure, reduce the adsorption force of the dust and the film, so that the charged dust can be separated from the surface of the film under the action of the electric field, and move toward the positive charge dust removal device and the film. The negative charge dust removal device moves in the direction. During the pulling process of the film, the utility model firstly removes the dust with negatively charged ions through a positive charge dust removal device at a relatively fast air flow rate, and then removes the positively charged dust through a negative charge dust removal device at a relatively fast air flow rate The ionic dust and the electrically neutral dust are removed together with the film due to the weak adsorption force due to the electrical neutrality during the film pulling process under the 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.

Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1, a non-contact type film dust removing device includes at least two sets of dust removing mechanisms of a fan 2, the dust removing mechanisms are respectively disposed at two sides of a film 1, the dust removing mechanisms include a positive charge dust removing device 3 and a negative charge dust removing device 4, the fan 2 is disposed at one side of the positive charge dust removing device 3 and one side of the negative charge dust removing device 4 for generating wind pressure and reducing an adsorption force between dust and the film 1, so that charged dust is separated from the surface of the film 1 under the action of an electric field and moves towards the positive charge dust removing device 3 and the negative charge dust removing device 4. The utility model discloses at film 1 at towed in-process, earlier through positive charge dust collector 3, detach the dust of the negative charge ion under faster air flow rate, then through negative charge dust collector 4, detach the dust of the positive charge ion under faster air flow rate, electrically neutral's dust is at film 1 traction in-process, because electrically neutral's the reason, and is weaker with 1 adsorption affinity of film, gets rid of in the lump under faster air flow rate. In the positive charge dust removal device 3 and the negative charge dust removal device 4, the positive charges and the negative charges do not contact the film 1, the static electricity on the surface of the film 1 is not attenuated, and the surface of the film 1 is not damaged.
Specifically, the positive charge dust collector 3 includes a first metal plate 31 and a direct current negative high voltage generator 32 connected to the first metal plate 31, the negative charge dust collector 4 includes a second metal plate 41 and a direct current positive high voltage generator 42 connected to the second metal plate 41, and the first metal plate 31 and the second metal plate 41 are close to the membrane 1.
Preferably, the DC positive high voltage generator 42 generates a positive voltage of 15Kv-30Kv, and the DC negative high voltage generator 32 generates a negative voltage of 15Kv-30 Kv.
