Abstract

The invention discloses a powder covering and sweeping device during electrostatic powder spraying. The powder covering and sweeping device comprises a powder room provided with an inlet and an outlet, wherein an end part blowing device is arranged at the outlet in the powder room; a side part air screen device is arranged on each of two sides of the width of a sprayed base material in a traveling direction; the end part blowing device and the side part air screening devices are mounted and connected to corresponding connecting and fixing structures on a side wall of the powder chamber or a ground surface of the powder chamber. The device is used for sweeping and removing powder attached to a plate surface not required to be sprayed with the powder; compressed air screens are formed for covering excess powder floating from the two sides of the sprayed base material and sweeping and removing the powder attached to a side part of the surface, so that the plate surface not required to be sprayed with the powder on the side can be guaranteed to be clean, the requirement on a condition that the surface is subjected to a next working procedure or process can be met, the efficiency is high, and the effect is good; flow, a position far away from the plate surface and an angle for each spray nozzle can be all adjusted, the spray nozzle also can be closed to meet an actual working condition, and the device is simple and convenient to operate.

Description

technical field

[0001] The invention relates to the field of powder electrostatic spraying, in particular to a powder cleaning and shielding device for continuous electrostatic powder high-speed spraying of flat intermittent steel plates, aluminum plates, or steel coils and aluminum coils. Background technique

[0002] At present, electrostatic powder spraying is used in the world to carry out electrostatic spraying on the surface of metal structural parts, cold-rolled steel plates, galvanized steel plates and aluminum plates.

[0003] Among them, for the spraying of the board, when spraying two different colors of powder on both sides of the board, one color should be sprayed on one side first, and the other side does not need to be sprayed for the time being. It is inevitable that the excess powder sprayed on one side will fall and adhere to the other side, so the side that does not need to be sprayed with powder should be protected.

[0004] Generally, when one side of t...

Embodiment Construction

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the multi-layer invention of the present invention will now be described with reference to the accompanying drawings.

[0031] see figure 1 , the powder shielding and cleaning device in the electrostatic powder spraying of the present invention, comprises the powder room 1 with inlet and outlet, the end purge device 3 that is positioned at the outlet 2 places in the powder room, and is sprayed along the base material 4 Side air curtain devices 6 are respectively arranged on both sides of the width of the running direction 5 . figure 1 The designed structure is as follows: powder coating is carried out on the bottom of the board surface, powder shielding and cleaning devices are installed on the top of the board surface for purging, and the direction of the compressed air nozzle 7 is directed downward. In the same way,...
