Description

Technical Field

[0001] The utility model relates to the technical field of oil presses, in particular to an oil press with a spiral pressing shaft. Background Art

[0002] Screw oil press is a widely used oil pressing equipment. The main part of the screw oil press is the pressing chamber, which includes a cylinder and a screw shaft rotating in the cylinder. The working process is to use the continuous rotation of the screw shaft to drive the screw. As the pitch decreases or the root circle diameter gradually increases, the volume of the internal space of the pressing chamber continues to shrink and a pressing effect is produced. The squeezed oil is squeezed out from the gap in the pressing cage, and the residue is pressed into crumb-like cakes, which are continuously discharged from the oil residue discharge port at the end of the pressing chamber.

[0003] The grease is squeezed out from the gap of the pressing cage and flows on the guide plate, and then flows into the collection barrel through the guide plate. Since the freshly squeezed grease contains impurities and foam, impurities and dust in the air will inevitably remain on the guide plate after a period of use. The guide plate needs to be cleaned to ensure that the subsequent grease is not contaminated. If it is cleaned directly on the frame, the space is small and the grease cleaning is difficult. The existing guide plate is usually fixed to the frame with bolts, which is inconvenient to install and disassemble, resulting in low practicality of the device. Utility Model Content
