The invention discloses fast cleaning equipment for stainless steel product machining, and relates to the technical field of stainless steel product production. The fast cleaning equipment comprises acleaning box. The inner wall of the lower side of the cleaning box is fixedly connected with a fixed frame. A first motor is mounted on the fixed frame. The output end of the first motor is fixedly connected with a round part. Through the action of a mixing paddle, the homogenization effect of a cleaning agent is improved, the cleaning agent is prevented from being precipitated, and therefore thecleaning agent can be sprayed out evenly, and finally the cleaning quality is improved; due to the shape and due to the fact that the outer side face of the mixing paddle is in contact with the innerwalls of the upper portion and the lower portion, the homogenization effect is guaranteed, meanwhile, the cleaning agent is prevented from adhering to the inner wall of a cleaning agent mixing tank,and the interior of the cleaning agent mixing tank is kept clean; through the adoption of the mixing paddle, the effects of achieving homogenization and cleaning the inner wall of the cleaning agent mixing tank can be achieved at the same time, and cost is saved; and a plane belt does reciprocating motion, so that brush plates do reciprocating motion, the brush plates can fast clean workpieces, and the cleaning effect is improved.
