Technical Field

[0001] The present application relates to the field of spraying technology, and more specifically, to a device for spraying a surface of a building material. Background Art

[0002] For the purpose of aesthetics or corrosion protection, the surface of building materials needs to be sprayed. At present, spraying devices are usually manually sprayed with a spray gun when spraying the surface of building materials.

[0003] The document with prior art publication number CN213762396U provides a spray gun. In the related technology of the device, a cross guide hole is opened, and each cross guide hole is distributed in a circle with the central axis of the discharge valve, which can effectively improve the spraying area of ​​the spray gun and the uniformity of the coating spraying.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the gun body is spraying on the surface of building materials, it is unable to block the sprayed paint, which easily causes the splashed paint to adhere to the operator's hands and the surface of his clothes, making it difficult to clean.

[0005] In view of this, we propose a surface spraying device for building materials. Utility Model Content

[0046] The support rod 9 is hingedly mounted outside the stretch sleeve 8 and is hingedly connected to the flip rod 6 .

[0047] The device for spraying the surface of building materials utilizes a spray gun frame 1 to spray a mixture of paint and gas, and drives a stretching sleeve 8 to move in a limited position through a connected pull rope, so that a support rod 9 opens a flip rod 6, so that a plurality of umbrella cloths 7 form a barrier, thereby protecting the operator's hands from being stained with paint, and achieving a good protective effect.

[0048] Reference Figure 3-5 The negative pressure component 2 in the building material surface spraying device recorded in the embodiment of the present application includes a turbine barrel 21 fixedly connected to one side of the spray gun frame 1, and the air supply pipeline fixedly installed outside the turbine barrel 21 is fixedly connected to the air supply pipeline inside the spray gun frame 1, and the turbine barrel 21 is fixedly connected to a negative pressure pipe 22, and the other end of the negative pressure pipe 22 is fixedly connected to an isolation filter frame 23, and one side of the isolation filter frame 23 is fixedly connected to a double-way pipe 24, and the outside of the double-way pipe 24 is fixedly connected to multiple spring air pipes, and the other end of the spring air pipe is fixedly connected to a mist suction pipe 25, and the mist suction pipe 25 is fixedly connected to the flip rod 6.

[0049] The surface spraying device for building materials utilizes the spray gun frame 1 for spraying operation. The circulation of gas drives the turbine in the turbine barrel 21 to rotate, so that the rotating turbine barrel 21 generates a negative pressure suction effect under the centrifugal action. The turbine barrel 21 generates negative pressure suction under the centrifugal action, and forms an air suction port at the end of the connected mist suction pipe 25, which is convenient for adsorbing the paint mist sprayed and dispersed by the device, thereby improving the safety and protection of the device during spraying.
