Abstract
The invention relates to static steel plate plastic coating equipment and discloses color steel plate plastic coating equipment with a transverse high-voltage static bar. The color steel plate plastic coating equipment comprises static bars (1) and spray guns (2), wherein the spray guns (2) are located above a steel plate (4); and the static bars (1) are parallel to the plane of the steel plate (4). According to the invention, a plurality of guns are separated from one another; the static bars are located at the lower side of the spray guns, and perpendicular to the longitudinal direction in which the steel plate moves; the electrostatic field above the steel plate tends to be consistent so that spray coating is prevented from accumulation; and therefore, the thickness of the coating on the surface of the steel plate is balanced.
Description
Technical field
The present invention relates to steel plate static plastic-coated equipment, related in particular to a kind of horizontal high voltage electrostatic rod color steel plastic-coated equipment.
Background technology
At present, tradition plastic-coated steel plate, adopt multiple gun head plastic-blasting mode, as shown in Figure 1, because the electrostatic rod of each spray gun is positioned at spray gun center, when many operations of multiple gun, the electric field of each rifle is interlaced, and static generation interference phenomenon is piled up phenomenon thereby produce powder, make to be partial to a certain side thickness and increase, the rolling in later stage, die mould etc. are all brought to the bad phenomenon such as wrinkle.
Summary of the invention
When the present invention is directed to the above static electrification rod spray gun of one of available technology adopting and dusting, because electrostatic rod is positioned at spray gun center, cause, between the electrostatic field of each rifle, interference phenomenon occurs, thereby produce powder and the shortcoming such as pile up, provide a kind of multiple gun that utilizes separated, employing spray gun dusts, electrostatic rod is positioned at spray gun downside, and move longitudinally perpendicular to steel plate, the electrostatic field of steel plate top reaches unanimity, make spraying no longer pile up phenomenon, the horizontal high voltage electrostatic rod color steel plastic-coated equipment of the coating layer thickness equilibrium of surface of steel plate.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Laterally high voltage electrostatic rod color steel plastic-coated equipment, comprises electrostatic rod and spray gun, and spray gun is positioned at steel plate top, described electrostatic rod and steel plate place plane parallel.The roughness of surface of steel plate is 0-1000 μ m, by the larger roughness of surface of steel plate setting, is conducive to the absorption of powder coating.The roughness of surface of steel plate can be 10 μ m, 20 μ m, 30 μ m, 60 μ m, 100 μ m, 300 μ m, 600 μ m, 1000 μ m.
As preferably, described electrostatic rod is arranged on the top of steel plate, and in electrostatic rod, sense of current and steel plate moving direction have angle.
As preferably, between described spray gun and steel plate, screen cloth is set.After the long-time spraying of spray gun, on spray gun, can produce unavoidably the long-pending piece of powder, can stop that the long-pending piece of powder on spray gun directly drops on steel plate after screen cloth is set, thereby affect the spraying effect of steel plate.In like manner, electrostatic rod is also arranged on screen cloth top.
As preferably, described screen mesh size is 5-50 orders.
As preferably, described screen cloth is connected with vibrating device.By screen cloth is connected with vibrating device, when the long-pending piece of powder producing in spray gun or electrostatic rod drops on screen cloth, screen cloth, by ceaselessly vibrating, is shaken off the long-pending piece of powder uniformly, and is covered on steel plate.
As preferably, described electrostatic rod is more than two, is arranged in parallel, and spray gun is arranged between adjacent electrostatic rod.Because spray gun is arranged between adjacent electrostatic rod, and electric field between adjacent electrostatic rod is uniformity, avoided in prior art, between charged gun, electric field is mixed and disorderly, mutually, produce and disturb, cause producing powder and pile up phenomenon, make to be partial to a certain side thickness and increase, be unfavorable for the rolling in steel plate later stage and the defect of die mould.
As preferably, described spray gun is arranged on electrostatic rod top.Therefore, the powder of spray gun ejection, after electrostatic rod, is with electric charge uniformly, is conducive to produce Electrostatic Absorption effect with steel plate.
As preferably, the high-pressure electrostatic voltage in described electrostatic rod is 3-10 ten thousand volts.
As preferably, described electrostatic rod is connected with vibrating device.Avoid electrostatic rod due to standing for a long time, caused gathering in electrostatic rod too much powder.
As preferably, in described electrostatic rod, sense of current and steel plate moving direction are orthogonal.
The present invention is owing to having adopted above technical scheme, there is significant technique effect: the present invention adopts multiple gun separated, electrostatic rod is positioned at spray gun downside, and move longitudinally perpendicular to steel plate, the electrostatic field of steel plate top reaches unanimity, make spraying no longer pile up phenomenon, the coating layer thickness of surface of steel plate is balanced.

The toponym that in above accompanying drawing, each number designation refers to is as follows: wherein 1-electrostatic rod, 2-spray gun, 3-screen cloth, 4-steel plate, 5-electric field.
The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 4 and embodiment, the present invention is described in further detail:
Laterally high voltage electrostatic rod color steel plastic-coated equipment, as shown in Figures 1 to 4, comprises electrostatic rod 1 and spray gun 2, and spray gun 2 is positioned at steel plate 4 tops, described electrostatic rod 1 and steel plate 4 place plane parallel.The interior sense of current of electrostatic rod 1 and steel plate 4 moving directions are orthogonal.Electrostatic rod 1 is arranged on the top of steel plate 4.
Between spray gun 2 and steel plate 4, screen cloth 3 is set.After the long-time spraying of spray gun 2, on spray gun 2, can produce unavoidably the long-pending piece of powder, can stop that the long-pending piece of powder on spray gun 2 directly drops on steel plate 4 after screen cloth 3 is set, thereby affect the spraying effect of steel plate 4.In like manner, electrostatic rod 1 is also arranged on screen cloth 3 tops.
The difference of the present embodiment and embodiment 1 is, electrostatic rod 1 is arranged between screen cloth 3 and steel plate 4.Electrostatic rod 1 is for tiltedly establishing, and the interior sense of current of electrostatic rod 1 and steel plate 4 moving directions have angle.Be that the interior sense of current of electrostatic rod 1 and steel plate 4 moving directions are antarafacial, electrostatic rod 1 is four, four electrostatic rod 1 be arranged in parallel at same plane, powder powder after screen cloth 3 of spray gun 2 ejections evenly enters the static electric field of electrostatic rod 1, thereby make powder with electric charge, when powder contacts with steel plate, there is Electrostatic Absorption, thereby complete electrostatic spraying.
