Pressing device for presser

Abstract

The invention discloses a pressing device for a presser. The pressing device is characterized in that a base is provided with two upper brackets, main and auxiliary hydraulic cylinders are arranged on each upper support, two guide rods are positioned between the two upper brackets and fixed on the upper brackets respectively, pressing plates and accommodating plates are placed between the two upper brackets, outer convex edges are arranged on two radial sides of each pressing plate, outer rod holes are formed in the radial outer convex edges, inner rod holes are formed in the inner sides of the two outer rod holes, guide rods are placed in the outer rod holes, and ejector rods are placed in the inner rod holes. Piston rods of the two auxiliary hydraulic cylinders correspond to the ejector rods respectively. An accommodating cavity is formed in each accommodating plate, a feeding hole is formed in the upper edge of each accommodating plate, axial protrusions for pressing disks are arranged at the center of the same side of the pressing plates, and the pressing disks correspond to the accommodating cavities in the accommodating plates. Axial through holes are formed in the pressing disk, radial holes are formed in the lower side surface of the pressing plates and communicated with the axial through holes, and strainers are arranged outside the axial protrusions and the pressing disks. According to the pressing device, the pressing force is large, the oil / juice yield is high, the production efficiency is high, and the pressing device is suitable for pressing grease or moisture in materials.

Description

technical field [0001] The present invention relates to a press. Specifically, it is a pressing device on the press used to squeeze out the grease or water in the material. Background technique [0002] At present, in the edible oil production industry and the fruit and vegetable processing industry, most of the squeezers are used to squeeze out the oil in plants and the juice in fruits and vegetables. The squeezer is a double-screw squeezer, which uses the conveying spiral pusher mechanism to push the material entering the material box into the squeeze screw mechanism, and then reduces the pitch of the squeeze screw mechanism and increases the shaft diameter, and then Under the action of the screen wall and cone resistance, the liquid (grease or juice) contained in the material is squeezed out. Because this kind of press is a screw press, the pressing force is small, and the amount of single pressing is small. Not only is it difficult to squeeze out the oil or juice in th...

AI Technical Summary

Problems solved by technology

Because this kind of press is a screw press, the pressing force is small, and the amount of single pressing is small. Not only is it difficult to squeeze the oil or juice in the material, the oil / juice yield is low, and the production efficiency is low.
