In the prior art, when the oil press operates, the processed materials enter the barrel body from the feed hopper, and the materials are continuously pushed inwards by the rotation of a rotary pressing screw arranged in the barrel body to be pressed. Because the materials are carried out in the barrel body of the oil press in a moving state, under the condition of high pressure of the barrel main body, great frictional resistance is generated among the materials, the rotary pressing screw, the materials and the barrel body, and thus, friction can be generated among the materials and the micro materials to cause relative movement. On the other hand, as the diameter of the pressing rod of the rotary pressing screw is gradually increased and the thread pitch is gradually reduced, when the rotary pressing screw rotates, the material is driven by the screw to advance and turn outwards, and meanwhile, the material layer close to the surface of the screw thread of the rotary pressing screw also rotates along with the pressing rod of the rotary pressing screw. Thus, each material particle in the barrel body does not move with equal speed and same direction, but relative movement exists among the particles. The oil in the material is squeezed out through friction and extrusion and flows out from the strip discharge gap.
However, the rotary pressing screw of the oil press adopted in the prior art is a spiral cone structure with a gradually increased pressing rod diameter, when a material enters the oil press and passes through the rotary pressing screw with the shape, oil in the material cannot be sufficiently extruded, the material subjected to once friction and extrusion needs to be returned twice in the oil press to completely press the oil in the material, the operation process is time-consuming and labor-consuming, and the loss degree of the rotary pressing screw in the oil press is also improved.
