The invention discloses polishing and spraying integrated paint spraying equipment. The polishing and spraying integrated paint spraying equipment structurally comprises a body, a paint box, a polishing and spraying transmission device, a pump, a material pipe, a reverse motor, a column, a paint spraying controller, a lifting rod, a paint spraying head, a transfer platform, a limiting plate, a support frame and a dryer, wherein the column is welded to the left side of the body; the paint box is mounted on the left side of the body and is arranged on the bottom of the column; the polishing andspraying transmission device is arranged on the right side of the paint box and is movably connected with the body; the pump is mounted in the column and is connected with the material pipe; and the material pipe is connected with the paint box and the pump at the position of the paint spraying head. The polishing and spraying integrated paint spraying equipment has the beneficial effects that while polishing of a polisher through the reverse motor, dust is blown out of a box and is treated, the purpose of uniformly spraying paint is achieved by rotation of a rotary rack connecting rod with different lengths, baffles are arranged at two ends of a treatment box to prevent paint molecules from scattering in all directions, paint pollution of a working environment is relieved, the equipment is simple in framework and easy to operate, the working efficiency is improved, and the equipment is convenient to use.
