The invention discloses a filtering device for paint production. The filtering device comprises a bottom plate, a motor, a cushion plate, a fixed cylinder and a filter cylinder, and is characterized in that the bottom plate is arranged on a bracket; the motor is arranged on the bottom plate; the cushion plate is arranged on a drive shaft; the air cylinder is arranged on the cushion plate; a positioning ring is arranged on a piston rod; the fixed cylinder is arranged between the piston rods through connecting rods I; each connecting rod I is connected with the corresponding positioning ring; afixed block is arranged at the inner wall of the fixed cylinder; a connecting rod II, a material storage cylinder and screen holes are arranged on the filter cylinder; the connecting rod II is connected with the fixed block. The filtering device has the advantage that by arranging a flow guiding ring at the inner wall of the fixed cylinder, and setting the flow guiding ring into a funnel-shaped structure, the paint tossing out of the screen holes of the filter cylinder can be guided into an adjacent bottom filter cylinder along the inner wall of the fixed cylinder via the flow guide plate, sothat the paint filtering efficiency and filtering quality are improved, and the waste of paint is reduced.
