Description
Technical field
The invention belongs to field of coating, and in particular to it is a kind of can quickly colour changing and carry out multicolor spraying four color spray guns dress
Put.
Background technology
In paint industry now, monochrome spraying can not meet the production requirement of product, therefore need to be in spraying process
In as needed, in time carry out color switching, with meet spray production requirement.
The spray gun and color replacing system commonly used in current market are by pipeline, and color changing valve is connected into spray gun, controls colour changing
Valve, spray gun colour changing is realized, also needed to clean pipeline after colour changing in order to avoid colour mixture.Colour changing main flow is：Colour changing need to carried out
When, primary colors coating is cut off by color changing valve and entered；Connectivity trachea, the useless coating of native color in color changing valve to lance pipe is sprayed；
Cleaning solvent is connected, pipeline is cleaned；Switch color changing valve, new color coating is reached spray gun by pipeline.
Be present many defects in conventional lance and colour changing valve system, be mainly manifested in：
When the 1st, carrying out colour changing, the coating in color changing valve to one section of pipeline of spray gun need to be sprayed, cause paint waste, environment dirt
Dye；
When the 2nd, carrying out colour changing, after spraying primary colors coating, cleaning solvent need to be consumed pipeline is cleaned, reduce spraying effect
Rate, increase cost.If not cleaned to pipeline, direct colour changing, it may appear that mixed color phenomenon, reduce coating quality；
3rd, the pipeline of color changing valve to spray gun is long, makes decline of pressure, and spray pressure is unstable, influences coating quality；
4th, structure is numerous and diverse, and dismounting assembling is inconvenient；
5th, spray gun spraying is restricted big.
The content of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of four color spray gun devices, will be commonly used in multicolor spraying
Color changing valve rationally integrated with spray gun, be applicable to the shower nozzle of the multiple standards specifications such as fan-shaped and circle, ensureing to spray
While quality, quick colour changing is realized, improves spray efficiency, and reduces the waste of coating and cleaning agent, it is more environmentally friendly, it is more economical,
Suitable for high pressure and low pressure spray.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Four color spray gun devices mainly include spray gun
Base, fixing nut and No. 4 feed valve group, fixing nut is installed in the spray gun base lower end, for stationary nozzle；The spray gun
Base top installs No. 4 feed valve group.
Furtherly, the spray gun base includes base body and extension rod for spray gun, and extension rod for spray gun is consolidated with base body
Connect or be integrally formed calmly.
Furtherly, oil duct is provided with inside the spray gun base center base main body and extension rod for spray gun, under extension rod for spray gun
Side end is provided with spray material port.
Furtherly, side, cylinder, piston rod and spring in Guan Fang, gas and oil, the gas are included per the feed valve group all the way
Side is fixedly connected with spray gun base in oil；The Guan Fang and cylinder in gas and oil respectively with being just fixedly connected；The spring is placed on
Cylinder interior, spring upper end face withstand on cylinder inner top surface, and lower spring end withstands on piston rod upper surface；The piston rod runs through gas
Side and base body in cylinder, gas and oil, upper surface contact with lower spring end face, and because spring is compressed, in the active force of spring
Under, the oil duct entrance plane of piston-rod lower end face and base body is in close contact, reaches sealing effectiveness, piston rod can be in power
In the presence of, move up and down.
Furtherly, the Guan Fang offers liquid passage inlet, oil duct import and oil passage outlet；Side in the Guan Fang, gas and oil
Inside is provided with oil duct.
Furtherly, the liquid passage inlet connects tracheae by joint；The oil duct import passes through joint with oil passage outlet
Connected pipes.
Furtherly, square internal galleries and base body inside trapped fuel are under sealing ring effect in the Guan Fang, gas and oil
A closed space is formed, in off working state, coating enters from oil duct import, is discharged from oil duct import, forms one
Circulating reflux；In spraying operation, coordinated by the shower nozzle installed at extension rod for spray gun spray material port and carry out spraying operation.
Furtherly, increase is fed valve group according to demand, can realize 4 color above colour changings.
When inlet valve group is closed all the way for certain, liquid passage inlet stuffiness, piston rod under the pressure of the spring, its
The oil duct entrance plane of bottom end face and base body is in close contact, and piston seat internal holes do not connect with base body internal galleries
Logical, coating enters from oil duct import, is excluded from oil passage outlet, side and oil duct closed inside base body in Guan Fang, gas and oil
In space, interior circulation is carried out, avoids coating from depositing, it is ensured that paint stability, so as to ensure coating quality.
When certain road, feed valve group need to be operated, compressed air enters from Guan Fang liquid passage inlet, enters gas along gas circuit
Side in oil, and upwarded pressure to piston rod, piston rod is raised above, and spring is compressed, and the air in cylinder is arranged from exhaust outlet
Go out, while piston rod rises, the oil duct entrance planar separation of its bottom end face and base body, make oil duct connection spray gun bottom
The oil duct of seat, coating enters oil duct, and is sprayed at spray material port.
When that need to carry out colour changing, switching feed valve group, original work valve group liquid passage inlet stops supply, in the work of spring force
Under, piston rod is quickly pressed down against, and the bottom end face of piston rod 5 contacts simultaneously again with the oil duct entrance plane of base body
It is closely sealed under stress, make to reformulate confined space inside side and base body in Guan Fang, gas and oil, coating is carried out in its space
Interior circulation, this road feed valve group stop feed；New feed valve group compressed air enters from liquid passage inlet, opens the valve and is supplied
Material.
Compared with prior art, positive beneficial effect of the invention：
1st, color changing valve and spray gun being integrated, maximizes and shorten length of pipe therebetween, paint waste amount is few during colour changing,
Less than 3ml, environmental protection and economy；
2nd, spray efficiency is improved without carrying out cleaning to pipeline during colour changing, different colours coating switching cycle is 4-6S；
3rd, after integrating, the pipeline of color changing valve to spray gun greatly shortens, and spray pressure is stable, ensures coating quality；
4th, surface structure advantages of simple after integrating, small volume, saves space；
5th, extension rod for spray gun is provided with spray gun base, stronger adaptability can be coated with to polymorphic structure；
6th, oil duct sets interior circulation, avoids coating from depositing, it is ensured that paint stability, so as to ensure coating quality；
7th, mounting hole is threaded outside four color spray guns, makes its installing/dismounting simple, strong applicability.
8th, it present invention can be suitably applied to the shower nozzle for including the first-class standard specification of Fan spray head, circular jetting.Coordinate and carry out Special Graphs
The spraying operation of case.
