NOVELTY - The utility model graphene a lubricating oil producing device, comprising a barrel body, the top of the barrel body is fixedly connected with a cover plate, the middle part of the top end of the cover plate is fixedly connected with a motor, the driving end of the bottom of the motor passes through the cover plate and is fixedly connected with the top end of the rotating rod, one side of the outer wall of the rotating rod is provided with a plurality of lifting grooves, the inner part of the lifting groove is slidingly connected with a limiting piece. In the utility model, firstly starting the motor to make the rotating rod to rotate, under the action of limiting piece the rotating ring drives the sliding block to move in the sliding groove through the electric heating rod, because the sliding groove is inclined, and matched with the limiting piece in the lifting groove to slide, the electric heating rod in the barrel body to rotate while moving up and down; so as to improve the uniformity of the stirring; at the same time, starting the fan of the top plate to improve the fluidity of the air around the motor, so as to radiate the heat around the motor, improving the service life of the motor; at the same time, protecting the frame to a certain protection effect.
