Abstract
A coating spray control system comprises a coating preparation valve, the coating preparation valve is connected to a spray gun through a pneumatic pressure regulating valve, the pneumatic pressure regulating valve is communicated with a gas source through an electric proportion pressure valve, and the gas source is communicated with the spray gun through a pair of electric proportional flow valves in parallel connection. The coating spray control system further comprises a control unit connected with a computer, the control unit is connected with each electric proportional flow valve, a flow sensor is arranged between the coating preparation valve and the pneumatic pressure regulating valve, and the flow sensor is connected with the control unit. The control circuit of the control system, as well as coating and gas pipelines, is simple in structure, and the spray control to the coating is efficient and reliable.
Description
Technical field
The utility model relates to a kind of coating spraying control system.
Background technology
Japanning is the key step of coating application.For obtaining desirable filming, the conditions such as japanning efficient that must reach according to character, Workpiece structure and the requirement of coating are accurately selected method of lacquering.Except that traditional brushing method, now current method has spraying, electrodeposition coating, deposit application, dip-coating, roller coat and curtain automatically is coated with etc.
Spraying comprises that aerial spraying, high pressure airless spray, electrostatic spraying, double-headed spray gun spray gentle spray painting and be coated with etc.Aerial spraying is that the compressed air with 0.15～0.5MPa pressure sprays from the nozzle of spray gun; The air-flow that flow velocity is very high; Make nozzle form parital vacuum, will coat with lacquer liquid and suck this vacuum space (or deliver to nozzle with the pressure feeding manner), and make and coat with lacquer liquid and atomize immediately; Spray to surface of the work, form evenly smooth filming behind the levelling.The japanning efficient of this method is brushed high, and paint film is more smooth, but coating cloud flies upward contaminated air; Lacquer liquid utilization rate is merely 30%～50%, waste greatlyyer, only is used for general scale and constructs.High pressure airless spray is the high pressure that forms through the different piston of big small size with air, and (spray 0.2～1.0mm), lacquer liquid expands immediately in atmosphere and atomizes, and becomes very thin particulate, is ejected into surface of the work, and formation is filmed from superfine nozzle with coating.The japanning efficient of this method is high, is applicable to the spraying of mastic, in large-area construction such as shipping industry, science of bridge building, uses wider.Electrostatic spraying is under the effect of high voltage electric field, makes the coating cloud from the spray gun ejection, is with electric charge.This charged coating cloud, the surface of the work absorption to different electric charge is deposited as uniformly and films.The lacquer liquid utilization rate of this method can reach 80%～90%.Be mainly used in industries such as automobile, machinery, household electrical appliance, bicycle.The double-headed spray gun spraying is applicable to the construction of two-component coating.The coating of two components is in case mixing just begins crosslinking curing.With double-headed spray gun two components ratio is on request sprayed respectively from two nozzles, form aerosol and mix, be sprayed on the surface of workpiece, formation is filmed.Aerosol spraying be with fluoro trichloromethane or dichlorodifluoromethane or other liquescent gas as cast charge, mixes in the metal can of the sealing of packing into coating, on the jar hand push type minor valve is housed.During japanning, the lacquer liquid in the jar is fully shaken up, press the button then, the unlatching minor valve coats with lacquer the pressure that liquid is promptly borrowed cast charge gasification back generation, sprays from valve, is sprayed to be coated with on the surface, and formation is filmed, and is mainly used in family's small size application and car repair aspect.
The utility model content
The purpose of the utility model provides a kind of coating spraying control system.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
The coating spraying control system; Include coating configuration valve; Coating configuration valve is connected in spray gun through air vent valve, and air vent valve is communicated with source of the gas through electric proportional pressure valve, and source of the gas is communicated with spray gun through the electric proportional flow control valve of a pair of parallel connection; Also include the control module that is connected in computer, control module is connected respectively with each electric proportional flow control valve.
Be provided with flow sensor between said coating configuration valve and the air vent valve, flow sensor is connected in control module.
The beneficial effect of the utility model is, the control circuit of this control system and coating, gas piping structure are simple, and is efficient to the spraying control of coating, reliably.
