Problems solved by technology

The device is used to clean and remove the powder attached to the surface of the board that does not need powder spraying, and form a compressed air air curtain to block the excess powder floating from both sides of the substrate to be sprayed and clean and remove the powder attached to the edge of the surface, but The isolation effect of its actual use is not obvious, but it will cause the powder to fly everywhere, and the powder will still adhere to the surface of the board that does not need powder spraying

Embodiment 1

[0022] refer to figure 1 , Figure 5 , figure 1 , Figure 5 It is a structural schematic diagram of the first specific embodiment of the present invention. As shown in the figure, a non-contact isolation anti-mixing color pollution device for plate powder coating includes an isolated air-flow layer injection device and a negative pressure adsorption device. The isolated air-flow layer injection The device is installed on the side position of the non-spraying surface of the plate, and the negative pressure adsorption device is arranged in the advancing direction of the isolation air flow injection of the isolation air flow layer injection device or near the edge of the plate, so that the isolation air flow layer injection device and the negative pressure adsorption device An isolated airflow layer is formed between them. When the overspray powder floats and moves to the side of the non-sprayed board surface, it will be isolated by the isolated airflow layer, lifted and spraye...

Embodiment 2

[0033] In the specific implementation process of the present invention, it is also possible to select the scheme of using a negative pressure adsorption device alone to form an isolated airflow layer, such as Figure 6 as shown, Figure 6 It is a schematic structural diagram of the second specific embodiment of the present invention. In this embodiment, a separate negative pressure adsorption device is used to form an isolated airflow layer, which can also achieve the effect of powder isolation and anti-pollution and color mixing. work efficiency.

[0034] The negative pressure adsorption device can be composed of one or more negative pressure adsorption ports 6, and the angle b between the direction of the adsorption airflow of the negative pressure adsorption ports 6 and the end surface of the plate can be 0° to 270°, all of which can form a negative pressure on the plate. The isolation airflow layer isolated from the non-sprayed surface can all achieve the isolation effect...

Abstract

The invention discloses a plate powder spraying non-contact isolating and color mixing pollution preventing device. The plate powder spraying non-contact isolating and color mixing pollution preventing device comprises a negative pressure adsorption device, wherein the negative pressure adsorption device is positioned on the back surface of a spraying surface of a plate or positioned at the edge of the plate; an isolating air flow layer which can isolate a non-spraying surface is formed on the non-spraying surface of the plate by the negative pressure adsorption device; and when escaping and moving to one side with the non-spraying surface, over-spraying powder can be isolated by the isolating air flow layer, and is lifted up and adsorbed to the negative pressure adsorption device, movement of the over-spraying powder to space of the side with the non-spraying surface can be restrained and controlled effectively, effects of powder isolating and color mixing pollution preventing are achieved, films are not required to be adhered, a non-contact mode is implemented, and therefore, work efficiency is guaranteed.

Description

technical field [0001] The invention relates to the field of powder electrostatic spraying, in particular to a powder isolation and anti-pollution color mixing device for electrostatic powder spraying of steel plates, aluminum plates, or steel coils and aluminum coils. Background technique [0002] At present, in the field of electrostatic powder spraying, it is very difficult to spray two different colors of powder on the board. Generally, one side is first sprayed with powder of one color. Adopt contact isolation protection measures. Generally, the method of coating is used to protect and shield the surface. The above method is low in efficiency and high in cost. It needs to be coated and removed, and is suitable for spraying of low-speed flat plates. [0003] Chinese patent CN201510080409.3 discloses a powder shielding and cleaning device in electrostatic powder spraying, including a powder room with an inlet and an outlet, and an end purge device is arranged at the outl...
