Abstract
The invention relates to a coating spraying control system, which comprises a coating distribution valve, wherein the coating distribution valve is connected with a spray gun through a pneumatic pressure regulating valve; a flow regulator is connected between the pneumatic pressure regulating valve and the spray gun, and is connected with a return pressure controller through a coating return pipe; the pneumatic pressure regulating valve is communicated with an air source through an electric proportional pressure valve; the air source is communicated with the spray gun through at least two electric proportional flow valves connected in parallel. The coating spraying control system also comprises a control device connected with a main engine, wherein the control device is respectively connected with the electric proportional pressure valve and the electric proportional flow valves. The coating spraying control system is simple in structure and convenient to use, and not only can adjust coating spraying, but also can realize efficient and reliable control on coating spraying.
Description
Technical field
The present invention relates to coating-spraying apparatus field, be specially a kind of coating spray control system.
Background technology
Japanning is the key step of coating application.For obtaining desirable film, the conditions such as the japanning efficiency that must reach according to the character of coating, Workpiece structure and requirement, accurately select method of lacquering.Except traditional brushing method, now current method has spraying, electrodeposition coating, autodeposition application, dip-coating, roller coat and curtain painting etc.
Spraying comprises aerial spraying, high pressure airless spray, electrostatic spraying, double-headed spray gun spraying and aerosol spray etc.Various spraying is described below:
Aerial spraying sprays from the nozzle of spray gun with the compressed air of 0.15 ~ 0.5MPa pressure, the air-flow that flow velocity is very high, make to form parital vacuum around nozzle, paint liquid is sucked this vacuum space (or delivering to nozzle with pressure feeding manner), and paint liquid is atomized immediately, spray to surface of the work, after levelling, form the film of uniform ground.The japanning efficiency of this method is comparatively brushed high, and paint film is more smooth, but coating cloud flies upward, contaminated air.Paint liquid utilization rate is only 30% ~ 50%, and waste is comparatively large, only constructs for general scale.
High pressure airless spray is the high pressure formed through the piston that area is different with air, sprayed from superfine nozzle (0.2 ~ 1.0mm) by coating, paint liquid expands immediately in an atmosphere and is atomized, and becomes very thin particulate, be ejected into surface of the work, form film.The japanning efficiency of this method is high, is applicable to the spraying of mastic, applies wider in the large-area construction such as shipping industry, science of bridge building.
Electrostatic spraying is under the effect of high voltage electric field, makes, from the coating cloud of spray gun ejection, to bring electric charge.This charged coating cloud, to the surface of the work absorption of the different electric charge of band, is deposited as uniform film.The paint liquid utilization rate of this method can reach 80% ~ 90%.Be mainly used in the industries such as automobile, machinery, household electrical appliance, bicycle.
Double-headed spray gun spraying is applicable to the construction of two-component coating.The coating of two components, once mixing, just starts crosslinking curing.With double-headed spray gun, two components are sprayed by the ratio of the required respectively from two nozzles, form aerosol and mix, being sprayed on the surface of workpiece, form film.Aerosol spray be with fluoro trichloromethane or dichlorodifluoromethane or other liquescent gas as cast charge, mix with coating in the metal can loading and seal, tank be equipped with hand push type minor valve.During japanning, the paint liquid in tank is fully shaken up, then presses the button, open minor valve, the pressure that paint liquid generates after namely borrowing cast charge gasification, from valve ejection, be sprayed at and be coated with on the surface, form film, be mainly used in family's small size application and car repair aspect.
Summary of the invention
Technical problem solved by the invention is to provide a kind of coating spray control system, to solve the problem proposed in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Coating spray control system, comprise coating configuration valve, described coating configuration valve is connected with spray gun by air vent valve, flow regulator is connected with between air vent valve and spray gun, described flow regulator is connected with back pressure controller by paint return pipe, air vent valve is communicated with source of the gas by electro-pneumatic proportional pressure valve, described source of the gas is communicated with spray gun by least two electric proportional flow control valves in parallel, also comprise the control device be connected with main frame, described control device is connected with electro-pneumatic proportional pressure valve, electrically proportional flow control valve respectively.
Further, be connected with flow sensor between described coating configuration valve and air vent valve, described flow sensor is connected with control device.
