Abstract
The utility model discloses a single-nozzle spray gun for a multicolor spray coating machine, aiming at solving the technical problem that changed color residues exist in the existing multicolor spray coating device based on a color changing valve. The technical scheme is that a plurality of paint control modules (22) are arranged on a spray gun body (14). By arranging bidirectional intersected spiral groove paint passages on nozzle joint inner cores in cylindrical paint passages on the paint control modules to reduce the residues of paint and by the bidirectional intersected spiral groove paint passages to realize color mixing of residual paint and paint to be painted in a flow passage not only can the residues of the paint be reduced, but also the residual paint and the paint to be spray-coated are mixed through the shape of the flow passage to reduce the influence of the color of the residual paint, and the goal of preventing paint residues during color changing is achieved. By designing paint chambers in the paint control modules, the fluctuation of paint flow during spay coating is also reduced. Since the spray gun body is utilized to directly realize color changing and the structure of the spray gun can be extended according to the color changing amount by adopting a modularized design, the utilization efficiency of the spray gun is improved and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of spray gun, particularly relates to a kind of multicolor spraying machine single spray gun.
Background technology
Adopt multicolor spraying equipment can realize the fast spraying problem of complex pattern, especially can provide solution for the digital camouflage color spraying problem that proposes in recent years.For engineering spraying problem, monochrome spraying problem for body of a motor car, parts outward appearance, building wall is very ripe at present, yet the engineering problem that requires like this to realize the spraying of multiple color intersection in the spraying process for similar digital camouflage color does not also have good solution, and the main scheme of hand spray or employing spray gun+colour changing valve that adopts is realized at present.
With reference to Fig. 1, document 2 " publication number is the Chinese patent of CN201552087U " discloses a kind of modularization pneumatic control valve and has used spray equipment and the spray robot of this colour changing valve, what fills in Douglas Rodr, and ABB T ﹠ D Technology Ltd. adopts the colour changing valve to realize multicolor spraying in the document.This gun body+colour changing valve multicolor spraying scheme comprises colour changing valve 15 and gun body 18, and gas source connector 6,16 is installed on the colour changing valve 15, lacquer pipeline connector 9,14, and spray gun jointing 13.Gas enters gas circuit 7 by gas source connector 6 or gas source connector 16 during spraying, arrive gas cavity 5, be sealed in the gas cavity 5 by piston ring packing 4, form air pressure, promote piston 3 and overcome holddown spring 2 compressions that withstand between end cap 1 and the piston 3, thereby make piston 3 drive 8 motions of paint control push rod, open paint channel 12, paint is by lacquer pipeline connector 9 and lacquer paths 10, enter paint cavity 11, enter paint channel 12 and spray gun jointing 13 through the buffering back with stable flow velocity, and then arrive gun body 18 ejections.Determine to open air inlet 6,16 by the color that judge to need spraying in the spraying process and can select the color that will spray.
Above-mentioned existing multicolor spraying scheme has the following disadvantages:
First, when realizing multicolor spraying, the passage of paint is oversize, spray behind passage, spray gun jointing, spray gun inner flow passage and the nozzle via the colour changing valve, cause after the colour changing paint of previous color residual too many, cause the colour changing border accurately to control, the colour changing border is had the digital camouflage color spraying problem of requirement, have a strong impact on spraying effect, can't satisfy the spraying requirement.
Second, each can only realize double-colored input existing colour changing valve, for the colour changing problem more than the dichromatism (digital camouflage color generally requires more than four looks), can only be by several colour changing valves be linked together by the joint that is similar to the spray gun connecting joint, connect spray gun endways again and nozzle is realized, cause the paint channel far away apart from spray gun further to lengthen, increased the residual quantity of paint, cause it can't use and the spraying that the colour changing precision is had requirement.
