Description

All-round aluminum alloy polyurethane spray gun Technical Field The utility model relates to the technical field of spraying, in particular to a universal aluminum alloy polyurethane spray gun. Background The spraying method includes dispersing the spraying into uniform and fine mist drops by means of pressure or centrifugal force through a spray gun or a disc atomizer, and applying the mist drops on the surface of the coated object, wherein the spraying method can be divided into air spraying, airless spraying, electrostatic spraying and various derivative modes of the basic spraying modes, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying and the like, and the spray gun is required to be used when spraying operation is carried out, and the spray gun can be directly applied to the coating in the industry, namely, a simple spray gun, and can be installed in automatic equipment, such as an automatic glue sprayer, an automatic glue coater, an automatic paint sprayer, a coater and the like. In the common spray gun equipment in the market, a double-discharging pipeline design is generally adopted, namely, two discharging pipelines are arranged, a valve is respectively arranged on each pipeline, then, a thinner and narrower mixed spray pipeline is connected in a welding mode, the structure exposes obvious problems in the actual use process, when two liquids flow in the pipeline too fast or an operator tries to increase the flow speed to improve the working efficiency, the wind pressure of the equipment cannot synchronously follow the change of the flow speed, under the condition, the situation that materials are accumulated easily occurs in the spray gun, the spray gun is blocked, the whole spray work cannot be well and normally carried out, the continuity and fluency of the production operation are seriously influenced, the used pipeline wall material is an iron pipe, however, the smoothness of the inner wall of the pipe is poor, the polyurethane material has higher viscosity, when the polyurethane material contacts with the iron pipe with the unsmooth inner wall, strong cohesiveness is generated between the iron pipe and the iron pipe, polyurethane materials are gradually attached and accumulated on the inner wall of the pipe along with the continuous production operation, especially on the gun head and the gun barrel, the accumulation phenomenon is more serious, the gun head and the gun barrel are finally blocked, once the gun head and the gun barrel are blocked, the working difficulty of cleaning materials is extremely large, a large amount of manpower and material resources are required, a long time is also occupied, the normal use efficiency and the production progress of equipment are seriously influenced, in addition, serious defects exist in a material mixing link, the mixing proportion cannot be precisely controlled, the problem directly leads to the reduction of the foaming quantity, the product quality is difficult to reach the standard requirement, more importantly, the requirements cannot be well met for application scenes with high requirements on the mixed materials, because the accurate compatible use of various materials in different proportions cannot be realized, the application range of the equipment is greatly limited, the equipment cannot adapt to diversified and high-precision production requirements, and the equipment is in a disadvantage in market competition. In view of the above, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a universal aluminum alloy polyurethane spray gun that solves the problems and improves the practical value. Disclosure of utility model The utility model aims to provide a universal aluminum alloy polyurethane spray gun, which solves the problems and the defects of inconvenient equipment cleaning and lower mixing proportion control precision in the prior art. In order to achieve the purpose, the utility model provides a universal aluminum alloy polyurethane spray gun, which is achieved by the following specific technical means: The all-purpose aluminum alloy polyurethane spray gun comprises a gun body, a gun handle power supply switch wire, a white material conveying mechanism, a white material cleaning gun air pipe, a white material connector, a white material pipe valve, an air valve switch, a feeding switch, a gun head, a black material conveying mechanism, a black material cleaning gun air pipe, a black material connector and a black material pipe valve, wherein the gun body is of an approximately English L-shaped structure, one end of the gun body is fixedly connected with the gun head and communicated with the gun head, the air valve switch is arranged below one side of the gun body and communicated with the air valve switch, one side of the gun body is provided with the white material conveying mechanism, the white mate
