Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of spray gun.
Background technology
Spray gun is a kind of Spray painting tool of commonly using, comes to body surface spray paint or coating with spray gun, and is namely convenient quick again.In the current paint industry, using maximum is air gun, especially to the demanding product of film quality, such as sedan limousine, top-grade furniture etc., all adopts aerial spraying or air electrostatic spraying.
Spray gun in the market can be divided into three kinds basically according to the difference of its feed mode: hydrocone type spray gun, gravity type spray gun and pressure type spray gun.
The air gun that hydrocone type spray gun foot is extensively commonly used.The bottom of spray gun is with paint cup, and compressed air produces parital vacuum on every side in spray tip high velocity stream mistake, with coating inlet nozzle in the paint cup and be atomized into coating cloud and drip.Spray gun nozzle should not be vertically upward or downwards, in order to avoid coating spills from the passage of paint cup.
The gravity type spray gun uses when being miniature workpiece and touch-up paint, and its top attaches paint cup, down transports to spray gun by the deadweight of coating.Press the position of the relative spray gun axis of paint cup, be divided into central type and side type.In spraying application, central type is restricted the spray gun obliquity; Side type can still keep vertical by paint cup with different positions.The colour changing of gravity type spray gun, easy to clean, feed consumption is less, is suitable for colour changing frequently color spray technique and the fast dual-component coating of spraying curing rate.
The pressure type spray gun is by pressure coating to be transported to spray gun.The subsidiary paint cup of spray gun self, but spray gun is lightweight and optional position and angle spray operation.Be fit to use on workpiece gap formula, continuous spray or the finishing line, spray efficiency improves, and film quality is good.
Existing spray gun is because the air-flow cap assembly can not rotate, so that what gush out is that coating all is vertical strip, if need to spray gun be sprayed sidewards with hand during sidewards strip of spray, atomizing effect is poor, easily disperses.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed a kind of simple in structure, atomizing effect good, the spray gun that be difficult for to disperse.
Purpose of the present invention can realize by following technical proposal: a kind of spray gun, comprise the rifle body, batch can, thimble, described rifle body lower end is provided with handle portion, it is characterized in that, described rifle body leading section upper end is provided with for the batch can of placing coating, described rifle body rearward end offers groove and the above-mentioned interior sealing of groove is provided with resetting-mechanism, be formed with cavity between described resetting-mechanism and the groove inwall, described rifle body leading section is provided with the nozzle with discharging opening, described nozzle has inner chamber and above-mentioned inner chamber and batch can conducting, run through in the described rifle body and be provided with a thimble and above-mentioned thimble has centre bore, described thimble front end is arranged in the nozzle, described thimble front end has the gas outlet and above-mentioned gas outlet and discharging opening formation is tightly connected, described thimble rear end is fixed on the resetting-mechanism and by airflow hole and cavity conducting, offer the gas channel one and the gas channel two that are conducted in the described handle portion, described gas channel one and cavity conducting, the trigger component that is provided with control air-flow conducting between described gas channel one and the gas channel two or closes.
This spray gun is under original state, coating in the batch can is by the inner chamber of circulation duct flow nozzle, extraneous air pump station imports gas and flows to gas channel two, open trigger component, gas channel one and gas channel two conductings, air-flow passes gas channel one and flows into cavity, and it is outwards mobile that resetting-mechanism drives thimble, and the gas outlet of thimble moves in the inner chamber, meanwhile, air-flow flows into the centre bore of thimble by airflow hole, arrive at last the gas outlet, and the coating that drives inner chamber ejects via discharging opening, the coating that ejects is spray pattern, atomizing effect is good, and coating only ejects via the discharging opening of nozzle, is difficult for disperseing.
