Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil presses, in particular to a hydraulic oil press. Background Art

[0002] With the improvement of living standards, more people begin to pay attention to healthy diet. Edible oil, as an indispensable necessity in daily life, is more valued by people. High-quality edible oil is favored by more and more people. The production of edible oil is inseparable from the hydraulic oil press. The hydraulic oil press is a common equipment for processing and producing oil from oil crops such as peanuts, soybeans, rapeseed, and walnuts. When the existing hydraulic oil press is working, the material is first put into the oil pressing chamber, and then the pressure plate is driven by the hydraulic device to squeeze the material so that the oil contained in the crop is squeezed out. The squeezed oil flows into the oil receiving tray along the oil groove and is collected. Then the residue in the oil pressing chamber is taken out for the next oil pressing work. The traditional hydraulic oil press has only one oil pressing groove. It takes a lot of time to take out the residue after each oil pressing, and the production efficiency is low. After working for a long time, the residue will slowly accumulate and adhere to the inner wall of the oil groove. For a long time, it will block the oil groove and pollute the oil, affecting the product quality. For this reason, we propose a hydraulic oil press. Utility Model Content

At this time, the oil pressing chamber is located directly below the hydraulic cylinder, and the single-chip microcomputer controls the hydraulic station to work. The oil pump inside the hydraulic station runs, and the hydraulic oil is sent into the hydraulic cylinder through the oil pipe. The hydraulic oil drives the telescopic end of the hydraulic cylinder to move downward, and the pressure plate moves downward synchronously. The material inside the oil pressing chamber is compressed, and the oil in the compressed material is squeezed out. The oil slowly flows into the oil receiving plate along the oil groove, and then is collected through the oil outlet pipe until the oil in the material is completely squeezed out, forming a material slag block at the lower end of the oil pressing chamber to complete the oil pressing work.

[0028] The working principle of a hydraulic oil press provided by the utility model is as follows: when performing oil pressing, first pour the material into the oil pressing chamber 63, and then push one side, such as the right side of the oil pressing chamber 63, to the left until the guide wheel group 61 brings the limiting column 8 at the lower end of the oil pressing chamber 63 to contact the outer edge of the load-bearing seat 7. At this time, the oil pressing chamber 63 is located directly below the hydraulic cylinder 51, and the single-chip microcomputer 9 controls the hydraulic station 53 to work. The oil pressure pump inside the hydraulic station 53 runs to send the hydraulic oil into the hydraulic cylinder 51 through the oil pipe. The hydraulic oil drives the telescopic end of the hydraulic cylinder 51 to move downward, and the pressure plate 52 moves downward synchronously. The lower end of the pressure plate 52 contacts the upper end of the scraper 64, and the scraper 64 is forced to move downward, and the spring 66 is compressed. As the telescopic end of the hydraulic cylinder 51 continues to move downward, the oil pressing chamber The material inside 63 is compressed, and the pressure of the hydraulic cylinder 51 on the oil pressing chamber 63 is getting greater and greater. The force on the damper 62 reaches the limit, and the telescopic end of the damper 62 contracts downward, and the oil pressing chamber 63 moves downward accordingly, until the bottom end of the discharge door 69 contacts the upper surface of the load-bearing seat 7. At this time, the pressure on the oil pressing chamber 63 acts on the load-bearing seat 7, and the load-bearing seat 7 forms a supporting effect on the oil pressing chamber 63, effectively avoiding damage to the support frame 1 during the oil pressing process. As the telescopic end of the hydraulic cylinder 51 continues to move downward, the scraper 64 moves downward synchronously, and the scraper 64 scrapes off all the residue and grease attached to the inside of the oil tank, and the oil in the compressed material is squeezed out, and the oil slowly flows along the oil tank into the inside of the oil receiving pan 67, and then is collected through the oil outlet pipe 68 until the material The oil is completely squeezed out, and a slag block is formed at the lower end of the oil pressing chamber 63, completing the oil pressing work. The single chip microcomputer 9 controls the hydraulic station 53 to work, and the telescopic end of the hydraulic cylinder 51 moves up until it returns to its original position. The pressure plate 52 leaves the upper end of the scraper 64, and the spring 66 rebounds without being stressed, and the scraper 64 also moves up with it, and the oil tank is scraped and cleaned again. The damper 62 is also not stressed, and the telescopic end of the damper 62 extends upward, lifting the oil pressing chamber 63 back to its original position, and then pushing the oil pressing chamber 63 to the right. The guide wheel group 61 brings the right oil pressing chamber 63 back to its original position, and then pushes the left oil pressing chamber 63 to the right, until the left oil pressing chamber 63 is located directly below the hydraulic cylinder 51. The single chip microcomputer 9 controls the hydraulic station 53 to work, and the hydraulic cylinder 51 pushes the inside of the left oil pressing chamber 63 again The material is squeezed out, and at the same time, the handle on the discharge door 69 at the lower end of the right oil press chamber 63 is grabbed and pulled hard, and the discharge door 69 is pulled out through the avoidance port 3, and the slag blocks inside the right oil press chamber 63 fall out without restriction and are taken out through the slag port 4, completing the slag discharge work, and then the right oil press chamber 63 is filled with materials again.
