Electrostatic powder spraying trolley for multi-branch-path electrostatic external arrangement

Abstract

The invention relates to an electrostatic powder spraying trolley which comprises a base with wheels and a frame fixedly mounted on the base, wherein the frame is inversely U-shaped; sliding brackets capable of moving up and down along the frame are arranged on two vertical columns in a sleeving manner; cantilever beams are mounted on the two sides of each sliding bracket; sprayers are mounted on the cantilever beams; a spiral screw rod lifter is arranged between the two vertical columns of the frame on the base; transmission rods mounted in a sliding pair supporting seat are arranged between the spiral screw rod lifter and the cantilever beams; the sliding pair supporting seat is mounted on the inner side of one vertical column of the U-shaped frame. The trolley is used for mounting a terminal sprayer in a multi-branch-path external arranged electrostatic powder spraying device onto mobile machinery capable of respectively swinging in the vertical direction or swinging in the transverse direction and is large in electrostatic powder spraying amount; therefore, sprayers can be tidily and tightly arrayed and moved integrally.

Description

technical field [0001] The invention relates to the field of powder electrostatic spraying, in particular to a continuous electrostatic powder spraying device for flat intermittent steel plates, aluminum plates, or steel coils and aluminum coils, in particular, to an electrostatic powder spraying device for multi-channel electrostatic external placement trolley. Background technique [0002] At present, the electrostatic powder spraying method is used to spray the surface of metal structural parts, cold-rolled steel sheets, galvanized steel sheets and aluminum sheets in the world. The electrostatic generator requires a small amount of electrostatic powder per unit time. [0003] Because the size of the metal structure to be sprayed is small or the surface area is small, the running speed on the continuous spraying line is small, and the amount of sprayed powder required per unit time is small, so the charge of each powder electrostatic sprayer on its sprayed powder The cap...

AI Technical Summary

Problems solved by technology

However, the high-power high-voltage electrostatic generator has a large structural size and cannot be installed inside a separate powder electrostatic sprayer, but must be installed outside the sprayer.

[0006] In addition, the above-mentioned electrostatic powder sprayer with built-in electrostatic generator is used in occasions where the demand for electrostatic powder is not large, so generally there are not many sprayers on the traversing trolley carrying the spray gun, and because the objects to be sprayed are all small special-shaped parts, Therefore, the sprayers need to be evenly arranged and the spacing is relatively large, so it is difficult to arrange the cables, powder pipes, and compressed air pipes input by each sprayer together.
