Abstract
The utility model provides an electrostatic fluidized powder plastic-coated device. The utility model is characterized in that the lower side of the micropore plate of a fluidized bed is provided with a copper screen, a copper coil, a copper rod, a poriform polythene net and an air dividing pipe; a perforated plate is arranged in an aspirator. Thevoltage and the contact time of workpieces and powders are adjusted, the coat with the uniform thickness can be obtained, and the operation is safe; the utility model is suitable for continuously coating anticorrosive, insulating and ornamental plastic coats on the metal surfaces of wires, nets, belts, pipes, pipe catchers, springs, electric products, etc.
Description
The utility model relates to a kind of continuously on material surface, and particularly the continuous electrostatic fluidized powder of coating powder plastics is coated with molding apparatus on the workpiece such as various wires, net, band, pipe, spring, pipe catcher, electric product.
It is to place an electrode that connects the negative high voltage electricity in fluid bed in the powder above the microwell plate that existing electrostatic fluidised power is coated with molding apparatus, electrode is embedded in the powder, near trapped electrons when powder flows electrode and charged relies on electronegative powder to be adsorbed onto on the workpiece of ground connection.The shortcoming of this method: the one, powder is charged insufficient, counter ion stream takes place when coating reaches certain thickness impact, and coating produces pockmark and corner avalanche; Two layers of electrode directly contact with powder, and are dangerous.Thereby influence coating quality, and bring Danger Electric shock risk to the operator.
The purpose of this utility model is to provide a kind of improved continuous electrostatic fluidized powder to be coated with molding apparatus, and it can obtain uniform powder coating, makes handling safety reliable again.
The purpose of this utility model is achieved in that following copper mesh, copper coil, copper rod and the poroid polythene net installed of the microwell plate in fluid bed, they contact with each other, and copper rod is connected with high-voltage DC power supply, at the bottom of polythene net dress air isocon, when coating (horizontal) or below above fluid bed when coating (vertical) adorns draught hood.When compressed air is air ion from following just being ionized during through copper mesh, copper coil of polythene net, Ionized air suspends flow of powder in the fluid bed by microwell plate and is electronegative, forms the powder particle cloud.When the metal works of ground connection passed through from formed electrostatic field, powder will automatically be adsorbed onto on the metal surface, forms uniform coating.
Different with the static fluidizer that electrode is set in powder, the utility model can not only make powder fully charged owing to take air ionization, and fool proof, allows the operator to contact with powder with workpiece.Coating layer thickness is by decision time of contact of the voltage of giving the charging of copper mesh and copper coil and workpiece and powder.Adjust voltage and just can obtain desired coating layer thickness time of contact.
Fig. 1 is the three-dimensional icon of horizontal applying device of the present utility model.
Fig. 2 is the three-dimensional icon of vertical applying device of the present utility model.
Fig. 3 is the profile that the utility model electrostatic fluidised power is coated with molding apparatus.
Describe the structure and the working condition of this device in detail below in conjunction with Fig. 3.
This device comprises one when coating (horizontal) or two when coating (vertical) fluid bed main body (1), the microwell plate (2) that usefulness of each main body (1) center fixed 4～10 metafiltration cloth are made.Bottom is equipped with three layers of copper mesh (3) at microwell plate (2), two-layer copper coil (9) is housed between them, side at the intermediate layer copper mesh is equipped with copper rod (10), and copper rod (10) is connected with high-voltage DC power supply (6), in the bottom of bottom copper mesh poroid polythene net (11) is housed also.In the bottom of polythene net (11) the polyvinyl chloride air isocon (4) that both sides have Φ 5～10mm pore is housed, isocon (4) is connected with air feed machine (7).Draught hood (5) is equipped with in when coating (horizontal) or below above fluid bed when coating (vertical), and porous plate (12) is housed in the draught hood (5), and draught hood is connected with Powder Recovery dust collect plant (not drawing among the figure).
During work, clean compressed air is sent into from the fluid bed bottom by isocon (4), just be ionized to Ionized air when passing through polythene net (11) with the copper rod that is connected with high-voltage DC power supply (10), copper mesh (3), copper coil (9), Ionized air suspends powdered plastic by microwell plate (2) and is with electric charge, when the metal works (8) of ground connection passed through coating chamber continuously, charged powder particle just was adsorbed onto the powder coating that acquisition needs on the surface of the work under the effect of electrostatic field.Immediately workpiece is sent to levelling curing in the plasticizing stove then, just forms and film uniformly.The exhausting dust collect plant has prevented that powder is excessive in the coating process, has improved operating environment, and has further improved the uniformity of powder coating.
