Electrostatic powder spraying trolley for multi-shunt electrostatic external

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 device for continuous electrostatic powder spraying of flat intermittent steel plates, aluminum plates, or steel coils and aluminum coils, and in particular to an electrostatic powder spraying device for multi-branch electrostatic external Trolley. Background technique [0002] At present, the spray guns carried on the spray trolleys that use electrostatic powder spraying to spray the surface of metal structural parts, cold-rolled steel plates, galvanized steel plates and aluminum plates have electrostatic generators inside each spray gun and are built in separately The electrostatic generator requires a small amount of electrostatic powder per unit time. [0003] Because the metal structure size or surface area to be sprayed is small, the running speed on the continuous spraying line is small, and the amount of spraying powder required per unit time is small, so each ele...

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.
