Description

Technical Field

[0001] This utility model relates to the field of color-coated steel sheet processing technology, specifically to an electrostatic spraying device for high-gloss powder coating for color-coated steel sheets. Background Technology

[0002] Color-coated steel sheet is a type of steel sheet with an organic coating. It boasts advantages such as good corrosion resistance, vibrant colors, attractive appearance, easy processing and forming, and the retention of the original strength of steel. It is widely used in industries such as construction, home appliances, and transportation. During the production process of color-coated steel sheets, electrostatic spraying of high-gloss powder coatings is often used to further enhance their decorative and protective properties.

[0003] However, existing electrostatic spraying equipment lacks the function of quickly recycling and reusing excess powder during actual use. This results in some powder not coming into contact with the board during the spraying process, leading to powder waste. To address this, we propose an electrostatic spraying device for high-gloss powder coatings on color-coated steel sheets. Utility Model Content

[0004] The purpose of this invention is to provide an electrostatic spraying device for high-gloss powder coatings for color-coated steel sheets, so as to solve the problems mentioned in the background art.

[0009] Preferably, a baffle is fixedly connected to the outer side of the connecting rod, and a suction hole is provided on the inner side of the baffle.

[0010] Preferably, one side of the baffle is connected to the inner cavity of the reserved hole through a pipe, and a vacuum cleaner is fixedly connected to one side of the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a sliding plate to engage with the inner cavity of the slide groove and pushes the sealing plate downward to seal the bottom of the sealing plate with the top of the collection box. The filter box filters the powder and air, retaining the powder in the inner cavity of the filter box and expelling the air. By rotating the limiting screw, the limiting screw enters the inner cavity of the first limiting hole on both sides of the filter box to limit and fix the filter box.

[0013] 2. In this utility model, a first motor drives a rotating rod to rotate, which in turn drives a rotating cylinder to rotate. The rotating cylinder then drives a transmission belt to rotate, moving the sheet material. The material pump is started to deliver the material to the inner cavity of the electrostatic spray gun for spraying. A second motor drives a threaded rod to rotate, causing the threaded sleeve to move the connecting rod and baffle downwards to seal both sides of the spray box. The vacuum cleaner generates negative pressure suction to adsorb the powder that has not been in contact with the sheet material, causing it to enter the inner cavity of the filter box.
