Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the above-mentioned spraying gun is spraying, the compressed air enters the gun body from the air inlet joint, enters the amplitude adjustment device through the air valve, and divides the air flow into main, Secondary two-way airflow, the main airflow is sprayed from the gap between the nozzle and the flow cap and sucks the paint out of the paint pot, and the secondary airflow is sprayed from the two corners to atomize the paint to form a uniform spray width to achieve Spraying on the surface of the object to be coated, but when this spray gun sucks the paint out of the paint pot and sprays it, the paint will disperse around when it is sprayed from the nozzle. During the dispersion process, it is easy to make the paint Sprayed to the extent that the object to be coated does not need to be sprayed, resulting in waste of paint

Embodiment 1

[0042] refer to figure 1 , figure 2 , is an air curtain spray head disclosed by the present invention, including a main spray head 1 for spraying paint, an air flow piece 2 surrounding the main spray head 1 is arranged on the outer wall of the main spray head 1, and the air flow piece 2 is used to spray air flow to form a restriction The main spray head 1 sprays the air curtain space 5 of the paint range.

[0043] The airflow part 2 includes several airflow nozzles 3 fixedly connected to the outer wall of the main nozzle 1. In this embodiment, the number of the airflow nozzles 3 is preferably six, and the six airflow nozzles 3 are evenly arranged along the circumferential direction of the main nozzle 1. ; The air jet direction of each air nozzle 3 is the same as the direction in which the main spray nozzle 1 sprays paint.

[0044] The main nozzle 1 comprises a nozzle 11 and a nozzle opening 12 arranged at one end of the nozzle 11, and the nozzle 11 is provided with an air p...

Embodiment 2

[0048] refer to image 3 , Figure 4 , based on a further improvement of Embodiment 1, an air curtain spray head, including a main spray head 1 for spraying paint, the outer wall of the main spray head 1 is provided with an air flow piece 2 surrounding the main spray head 1, and the air flow piece 2 includes several along the main spray head. The airflow nozzles 3 uniformly arranged in the circumferential direction of the nozzle 1, the airflow injection direction of each airflow nozzle 3 is the same as the direction in which the main nozzle 1 sprays paint.

[0049] On the outer wall of the main nozzle 1, the position corresponding to each air flow nozzle 3 is fixedly connected with a connecting rod 13, and the end of the connecting rod 13 away from the main nozzle 1 is fixedly connected to the outer wall of the corresponding air flow nozzle 3, and the air flow nozzle 3 Including the pipe body 31, the two ends of the pipe body 31 are provided with an air inlet 32 ​​and an air ...

Embodiment 3

[0051] refer to Figure 5 , Image 6 , based on a further improvement of Embodiment 1, an air curtain spray head, including a main spray head 1 for spraying paint, an air flow member 2 surrounding the main spray head 1 is arranged on the outer wall of the main spray head 1, and the air flow member 2 is used for spraying air And form the air curtain space 5 that limits the scope of spraying paint by the main spray head 1.

[0052] The main nozzle 1 includes a nozzle 11 and a nozzle opening 12 disposed at one end of the nozzle 11 , and a connecting air passage 42 communicated with the nozzle opening 12 is opened in the nozzle 11 along the axial direction.

[0053] The airflow part 2 includes an airflow ring 4 sleeved on the outer wall of the main nozzle 1. The airflow injection direction of the airflow ring 4 is the same as the direction in which the main nozzle 1 sprays paint, and the end surface of the airflow ring 4 is provided with a ring along the circumferential direction...

Abstract

The invention relates to an air curtain sprayer and a spraying gun applying the same. The air curtain sprayer comprises a main sprayer for spraying paint, wherein an airflow piece around the main sprayer is arranged on the outer side wall of the main sprayer and is used for spraying airflow to form an air curtain space for limiting the paint spraying range of the main sprayer. The airflow piece isarranged to form an air curtain space range, so that the paint sprayed out by the main sprayer is sprayed within the air curtain space range to reduce the situation that the paint is sprayed to the surface, needing no spraying, of a to-be-sprayed article, paint waste is further reduced, and volatilization of the wasted paint is reduced to reduce pollution to the environment and facilitate environmental protection.

Description

technical field [0001] The invention relates to the technical field of spray guns, in particular to an air curtain spray head and a spray gun using the air curtain spray head. Background technique [0002] The spraying gun is mainly composed of a spray cap, a nozzle port, a needle valve and a gun body. At the same time, it is connected to a compressed air source such as a pressure tank. During operation, the compressed air is used to atomize the paint into fine paint droplets, which are sprayed to the surface of the object to be coated by the airflow. Surface, at present, when carrying out range painting to the object to be coated such as wall surface, adopt spraying gun to carry out spraying usually. [0003] Existing spraying gun such as authorized announcement number is a kind of multifunctional spraying gun disclosed by CN201558765U, along the air flow channel in the gun body, is provided with material needle adjusting device, air valve, amplitude adjusting device, feedi...
