Electrostatic spraying equipment for metal plates

The invention belongs to the technical field of metal plate electrostatic spraying, and particularly relates to metal plate electrostatic spraying equipment which comprises a spraying chamber, a hoisting plate is fixedly connected to one side of a transfer column, clamping plates are slidably connected to the two sides in a fixing box, and a machining plate is hoisted into the spraying chamber through the two clamping plates to be sprayed. A cleaning plate is slidably connected into the spraying chamber, movable spray heads are slidably connected to the two sides of the cleaning plate, and dismounting plates are fixedly connected to the two sides of the spraying chamber through bolts. A metal plate is clamped and moved through a clamping plate, a transfer column is started to drive a hoisting plate to place the metal plate into a spraying chamber, a movable spray head moves in the spraying chamber to conduct electrostatic spraying on a machining plate, and after spraying is finished, a disassembly plate is di
