The invention discloses multifunctional coating equipment which comprises a box body, wherein a fan is arranged on the top of the box body; a mechanical arm is arranged on the outer wall of the box body; an electric push rod is arranged at one end of the mechanical arm; a clamping groove is formed in the bottom of the mechanical arm; an electromagnet is arranged inside the clamping groove; a fixing plate is arranged on the outer side of the box body; and a storage bin is formed inside the box body. The equipment disclosed by the invention works by a fan, the blown air blows outside an air nozzle via a connecting hose and an air outlet tube, the sprayed coating is blown dry and dust at an un-coated position is removed, and surrounding objects can be simultaneously sprayed by virtue of fourdischarge pipes on the outer side of the box body. In addition, the coated objects can be clamped on the fixing plate, and the fixing plate and the coated objects are pushed to the outer side of the box body. The lug and the clamping groove are matched to electrify the electromagnet, the fixing plate is firmly fixed, the surrounding coated objects are sprayed, and a closed space is formed with thefixing plate, so that the coating is prevented from being coated onto other objects, and the spraying environment is good.
